The filter press utilizes a special filter medium to apply certain pressure to the object, which makes the liquid dialysis out of a kind of mechanical equipment, is a commonly used solid-liquid separation equipment.
Applied to chemical industry in the early 18th century, it is still widely used in chemical industry, pharmacy, metallurgy, dyestuff, food, brewing, ceramics and environmental protection.
Function: to extract the solids in the mixture to realize the function of solid and liquid separation.
A. Classification of filtering methods: chamber pressure filter and belt pressure filter, diaphragm filter press and plate frame filter press.
B. Structure classification: beam filter press and belt filter press.
C. Pressure classification: hydraulic pressure, manual jack pressure, mechanical pressure.
The science used: physical and liquid physical properties.
Subject: coal technology (level I);
Mining mechanical engineering (second-level discipline);
Coal preparation machinery (level 3)
History: the first filter device appeared in the early 18th century and was used in chemical industry.
Scope of filter press:
Pharmaceutical, chemical, standard parts, pharmaceutical, metallurgy, non-standard screws, dyes, food, brewing, ceramics, oil refining, sewage treatment and other environmental protection industries.
Structural characteristics of
1. Using advanced Australian technology, the appearance is beautiful and generous.
2. Large structure rigidity, stable operation and low noise.
3. Equipped with advanced pretreatment equipment, low operating cost (good for sludge flocculation).
4. The gravity dewatering zone is equipped with advanced cloth material, so that the material can be distributed evenly, and the life of filter belt can be extended.
5. With super long gravity dehydration zone and wedge dehydration zone, the material is dehydrated to ensure that the material will not overflow in the crush area.
6. The roller is arranged in a scientific and orderly way, and the gravity dehydration, wedge dehydration, squeezing and dehydration are respectively discharged, without interference, and the diameter ratio of the dehydration roller is large and the dehydration effect is good.
Therefore, the production capacity is large, energy-saving and efficient.
7. High degree of automation of continuous operation from feeding to discharging mud cake. PLC interface can be set according to the need, which is convenient for centralized control of microcomputer.
8. The power transmission mechanism adopts mechanical or variable frequency stepless speed regulation, which has a large range and wide adaptability.
9. The filter belt has a reliable backwashing device to ensure the dehydration effect of the filter belt.
10. Adopt pneumatic tensioning and pneumatic automatic rectifying device to ensure the safe and normal operation of the filter belt.
11. Safe and reliable operation, adopting infrared safety protection and all-around emergency safety stop device.
12. According to different materials, different structures can be configured with high filtration accuracy.
L. The normal pressure filter can be used for feeding, and the whole machine should be checked thoroughly before each shift.
Mechanical compression drive parts and gearbox must be lubricated;
Hydraulic pressure oil storage tank and review of the working pressure of the hydraulic pressure station and hydraulic oil generally replaced once a year, to replace the hydraulic system should be - a comprehensive cleaning, the working pressure of the hydraulic pressure station is less than the oil cylinder maximum working pressure, but they should not be below minimum filtration pressure value, a large leakage caused by the moment, meeting attaint parts.
2. It is forbidden to start the operation of the filter plate less than the specified number, so as not to damage the machine parts.
Check the arrangement of filter plate before adding material, the filter cloth cannot have folding phenomenon, preventing the occurrence of large leakage;
The filter plate must be tightly packed tightly.
3, after all normal rear can pressure filter plate pressure filtration, the filter pressure and temperature must be within the prescribed scope, high filtration pressure will cause leakage, filtering the high temperature plastic filter plate deformation, when feeding slurry concentration is uniform.
There shall be no mixture;
After discharge cake filter cloth and filter plate must be rinsed clean, do not allow the residue paste on the sealing surface or feeding channel, otherwise it will affect the sealing of material flow and the filter plate, thus cause phase filter plate on both sides of the pressure imbalance, cause the filter plate deformation damage.
4, the choice of filter cloth must conform to the requirements of the propeller of filtration technology, should be shrunk before new filter cloth production, the hole diameter should be less than the filter plate aperture, the matching filter plate holes and hole of the plate should be relatively concentric, Jane should feed opening cloth tiejin compared.in addition, otherwise it will cause, filter, filter rate is low, cloth tube rupture, short of filtering the expected goal.
5. Filter press in the initial stage of press filter, filtering is more cloudy. When a filter cake is formed on the filter cloth, the filtrate will become clear.
If the filtrate is always cloudy or mixed, it may be the filter cloth damaged or the hole and plate hole deviation. The valve should be closed or the feed replacement filter should be stopped.
A small amount of leakage is allowed between the filters.
6. When moving the filter plate, the force should be evenly and properly. No collision or wrestling shall be allowed, so as not to damage the sealing surface and the filter wrench.
Filter cloth use after a period of time can harden, performance degradation, therefore requires periodic inspection, if found to have affected the phenomenon of filtration rate, change accordingly. You may use low concentration of weak acid weak base, and cleaning the filter cloth to restore function, unable to recover the timely replacement.
7. The slurry, lotions or compressed air valves must be enabled according to the operating procedures and cannot be enabled at the same time. The compressed air pressure should not exceed the filtration pressure when the diaphragm squeezes.
