Turning ore with disc filter
I hope it will be helpful to you. It's all information collected on the Internet. Please accept it. thank you
Working principle
the disc vacuum filter is composed of discs with indivial sector plates. Each fan-shaped piece is a separate filter unit, which is made of filter cloth and covered on the fan-shaped piece to form a filter chamber. The filter disc is driven by the motor through the recer and open gear drive. The filter disc rotates clockwise. The pulp in the filter chamber adheres to the filter disc in the adsorption area with the help of the pressure difference formed by the vacuum pump on both sides of the filter medium. After the filter cake is formed, the agitator rotates to prevent solid precipitation. After the filter cake leaves the liquid level, it continues to dehydrate under the action of vacuum. The filtrate passes through the filter cloth, passes through the filtrate pipe and is discharged from the distribution head. The filter cake is discharged by reverse blow in the discharge area and falls into the discharge tank, and the whole operation process is continuous circulation
working conditions
(1) the particle size of solid in pulp is - 100 mesh to - 400 mesh
(2) the pulp temperature is 10 ℃ - 50 ℃, non corrosive
(3) the optimum slurry concentration is 35% - 65% (metal minerals) or 20% - 40% (coal or other light materials)< (1) the fan-shaped filter plate is made of high-strength engineering plastics, and its service life is increased by 1-1.5 times
(2) the filtration number of filtrate pipe is large, and the abdominal cavity volume of distributor is large, which improves the pumping rate and filtrate discharge effect
(3) the wear-resistant nylon, single or multi filament filter cloth has the advantages of high cake removal rate, less blockage and long service life
(4) multi point dry oil pump centralized multi-point automatic lubrication
(5) the filter cloth automatic cleaning device maintains its good dehydration effect
(6) horizontal forced high-speed mixing, rubber and graphite packing at the shaft end and triple sealing with water pressure difference are adopted to prevent slurry leakage
(7) the main drive is continuously variable, which can be adjusted according to the concentration and flow of materials (AC speed regulating motor or frequency converter) in order to achieve the ideal working effect
(8) each plate is composed of 20 fan-shaped plates, which strengthens the control of filtration process and makes the cake thickness uniform
(9) the friction plate is made of special wear-resistant boron cast iron, which combines hardness with softness and has good sealing, and its service life is more than ten years
(10) the filtrate pipe is made of high-strength wear-resistant ceramic composite steel pipe, which can increase the service life by more than 10 times
(11) the lower flange of the interface between filtrate pipe and filter fan is removed, and the mold positioning is adopted for direct welding, which reces the possible air leakage points by 90%
when the pulp concentration is 30%, the processing coefficient is 50% - 55%. Hope to help you! You can have a private chat< br />QQ 2082214
the effect of disc filter is poor, but the price is cheap. It mainly depends on the working condition to decide which filtering method to choose.
