As people pay more and more attention to environmental protection, in oil and gas drilling projects, various Drilling Waste Management equipment is applied, such as High-G Dryer Shaker, Two Phase High-Speed Decanter Centrifuges, Three phase High-Speed Decanter Centrifuge, Vertical Cuttings Dryer, Vacuum Shaker Screen, etc. For different drilling wastes, many companies have given their own solutions. Among them, the filter press is more and more popular and widely used by people because of its excellent separation effect. The filter press uses a special filter medium to exert a certain pressure on the object to make the liquid dialyze out of a kind of mechanical equipment, which is a commonly used solid-liquid separation equipment.
Working Principle of ZH Filter Press for Drilling Waste Management
The filter press is generally composed of a head plate, a tail plate, a filter plate, a hydraulic cylinder, a main beam, a transmission and a pulling device. The hydraulic cylinder piston pushes the head plate, so that the filter plate is pressed against the adjacent filter plate to form a filter chamber; the mud pump is sent into the filter chamber, the water permeates the filter cloth and is discharged through the liquid outlet, and the solid mud forms a filter cake in the filter chamber. When the mud is full of the filter chamber, the high pressure pump is used to continue the pressure filtration of the mud, so that the solid and liquid are separated in the filter chamber.
Advantage of ZH Filter Press for Drilling Waste Management
- Adopt advanced technology, beautiful appearance.
- High structural rigidity, stable operation and low noise.
- Equipped with advanced concentration pretreatment equipment (good for sludge flocculation), low operating cost.
- The gravity dewatering area is equipped with advanced distributors to make the material evenly distributed and prolong the life of the filter belt.
- With super-long gravity dehydration area and wedge-shaped dehydration area, the material is fully dehydrated to ensure that the material will not overflow in the pressing area.
- The rollers are arranged scientifically and orderly. Gravity dehydration, wedge dehydration and pressing dehydration are discharged separately without interfering with each other. Therefore, the production capacity is large, energy saving and high efficiency.
- The continuous operation from feeding to discharging mud cake has a high degree of automation, and a PLC interface can be set up according to needs, which is convenient for centralized control by microcomputer.
- The power transmission mechanism adopts mechanical or frequency conversion stepless speed regulation, which has a large speed regulation range and wide adaptability.
- The filter belt is equipped with a reliable backwashing device to ensure the dehydration effect of the filter belt.
- Adopt pneumatic tensioning and pneumatic automatic deviation correction device to ensure the safe and normal operation of the filter belt.
- The operation is safe and reliable, using infrared safety protection and a full range of emergency safety parking devices. Filter belts with different structures can be configured according to different materials with high filtration accuracy.
