Special filter for gypsum in Luoyang Institute of mining

1. First, enable means to start using. Most of the objects involved in enabling it are objects

Second, detailed explanation:

1. In the Southern Song Dynasty, Liu Yiqing's "new sayings of the world · moral conct" said: "the town of Zhou has been closed, and Linchuan county is still the capital. Before it can reach the upper reaches, it lives in poqingxizhu. Prime Minister Wang looked at it. In summer, the storm came, and the boat was narrow and leaky, so there was almost no place to sit. Wang said, "why did Hu Weiqing get through this?" That is to say, it is Wuxing county. "

2. When did you reset your password? You can only log in with the new password after three days from that time. You can only use the previous password within these three days.

3.

After others use it, it will not be cancelled. After a period of time, the number will continue to be released. This is to reactivate the number

the bracket next to the number says that the number is used by others, but the number has been cancelled and put into the market again. Someone may call the previous owner of the number, and then explain the situation

it should be three months to six months after the number is cancelled, and the mobile company will put the mobile phone number on the market, but it should indicate "this number is the restart number" on the mobile phone number to inform consumers

extended data

after the cancellation of the telephone number, theoretically, it will be put back into the market for sale in three months. Because it may take more than three months for this number to be bought after it is put on the market again

there will be security risks when the number is re enabled, but it is not controlled by the operator. Because the businesses corresponding to those applications have nothing to do with operators, operators can't interfere with the operation of countless other commercial companies just because a certain number is cancelled

how to avoid security risks, after buying a new number, do not cancel the original number, and change the registered things one by one to the mobile phone number; If the bank binding can be changed in online banking, it can be changed in online banking. If you can only go to the counter, you can go to the counter. Any branch of the same bank in the country can change your mobile phone number. This is true of all banks (except some rural banks)

4. I learned that Gansu Jinchuan Group copper nickel concentrator used the foreign LAROX vertical filter press after flotation. Firstly, the equipment purchase is expensive, secondly, the maintenance is expensive, the maintenance is too troublesome, and the equipment is too complex; Later, the ceramic filter was used, but the water content and treatment capacity of the filter cake could not meet the requirements. Now, the intelligent high-efficiency filter press (quick opening diaphragm free automatic filter press) of Luzhou Changjie Filter Equipment Co., Ltd. is used, which is very good, and the water content and treatment capacity are up to the standard.

5. Gypsum powder is one of the five major gel materials. It plays an important role in the national economy. It is widely used in building, building materials, instrial molds and art models, chemical instry and agriculture, food processing and medical beauty, and so on. It is an important instrial raw material. Because it will float in the air in the process of proction and processing, so we need to take collection measures to control the spread of gypsum st, the most simple and effective way is to use the special bag filter for gypsum st
the use of bag st removal equipment can effectively rece the waste of gypsum, rece the harm of st to human body, and better protect the environment. Bag filter is a mature technology, low price, good quality, maintenance for 3 years. After years of scientific research and exploration, the bag filter is designed with large filtration area, high filtration efficiency, small floor area, simple and convenient operation and maintenance by introcing and adopting advanced high-tech technology at home and abroad and combining with the actual needs of gypsum st processing plant workshop in China. It is suitable for waste gas and st pollution control and material recycling in cement, chemical, asphalt mixing station, instrial kiln, electric power, woodworking, friction and brake pad manufacturing, stone processing, metallurgy, rubber, mining, coal mine, grain processing, waste incineration and other instries. It has high material recycling rate, no secondary pollution, and better concentration of economic and environmental benefits
gypsum st removal is an important link in gypsum proction process, and its normal operation is directly related to the normal operation of gypsum workshop. There is a plastic device in the gypsum st collector, and the temperature in the st collector can not exceed 200 degrees. If it exceeds the second network, the plastic device will soften and deform, and the whole system will be paralyzed, and the consequences will be unimaginable. In order to fundamentally solve this problem, we have installed a set of interlock device with temperature control for gypsum st collector. A thermometer with relay is installed on the instrument panel. The upper limit is set at 200 degrees. Below 200 degrees, the interlock is open circuit. The st collector works normally. When the temperature is greater than or equal to 200 degrees, the relay closes, the power supply of inced draft fan is automatically disconnected, and then the whole system stops, This effectively ensures that the st collector plastic device always works below 200 degrees, so as to ensure the smooth proction of gypsum workshop
today, the st remover is running normally. It not only purifies the air, strengthens the surrounding environmental protection, but also saves raw materials, so that part of the wasted raw materials can be reused. What's more, the workers are glad that it filters the st in the gypsum workshop, and the workers don't need to wear masks to go to work, which makes them feel happy and more energetic
there are four advantages of st collector in gypsum plant
1. Advantages of ash cleaning: the internationally advanced off-line three state (filtration, ash cleaning and static) ash cleaning method is adopted to avoid the "re adsorption" phenomenon ring ash cleaning, so that the ash cleaning is complete and reliable
2. Advantages of the pre st collecting mechanism: it not only greatly improves the st concentration at the inlet of the st collector, but also overcomes the disadvantage that the st directly washes the filter cartridge and is easy to wear
3. Advantages of key components: the key components that affect the main performance (such as pulse valve) are imported, and the service life of the vulnerable part diaphragm is more than 1 million times
4. Advantages of separate injection soot cleaning technology: one pulse valve can inject one column at the same time (the maximum number of filter cartridges in each column is 12). This design can greatly rece the number of pulse valves.

6. Gypsum dehydration to consider its concentration, temperature, particle size, processing capacity to select machinery and equipment. The effect of vacuum filter used in gypsum dehydration is good
principle of vacuum filter: under the action of pressure difference, the liquid (or gas) in the suspension passes through the permeable medium (filter medium), and the solid particles are intercepted by the medium, so as to realize the separation of liquid and solid
at present, Boyun ceramic filter is widely used in metal ore, sulfur, phosphorus, coal, silicon, quartz, mica and other concentrates, tailings dewatering, chemical instry zinc oxide, alumina, zinc sulfide, electrolytic slag, leaching slag, slag dewatering and environmental protection waste cement and waste acid treatment. The fineness of materials ranges from - 200 mesh to - 450 mesh and various ultra-fine materials.

7. There are still more powerful manufacturers of
diatomite filters in China, which are suitable for clarification and filtration of Baijiu, fruit wine, wine, health wine, beverages, syrup, soy sauce, vinegar, and liquid procts such as medicine, biology and chemical instry. Long filtration cycle, high efficiency, stable turbidity, good sealing, compact structure, convenient operation, movable and easy maintenance. Compared with similar procts, it can save 30% electricity, 60% water and 70% time< Baijiu: wine instry: fruit and vegetable juice, tea beverage, beer, yellow wine, fruit wine, liquor, wine,
sugar instry: sugar, fruit syrup, high fructose syrup, glucose syrup, beet sugar, honey and
condiments: vinegar, soy sauce, MSG, cooking wine,
pharmaceutical instry: antibiotics, vitamins, synthetic plasma, Br, etc. Chemical procts: resin, inorganic acid, organic acid, alcohol, benzene, aldehyde, ether, etc.
● others: gelatin, bone glue, seaweed glue, vegetable oil, starch, etc

8. The advantage of vertical filter press is that the moisture content of filter cake is relatively low, but the mechanism of the machine itself is complex, the operation and maintenance cost is high, and problems such as shotcreting and filter cloth damage are easy to occur. The operation and maintenance cost is higher, and the equipment maintenance time is long. Jinchuan Group began to use vertical filter press and ceramic filter for copper nickel concentrate filtration. Later, Luzhou Changjie intelligent high-efficiency filter press was fully used. It has the characteristics of quick opening filter press, full-automatic filter press and non diaphragm filter press. The moisture content can be comparable with vertical filter press, but the operation and maintenance cost is really low.
