Characteristics of filter plate：
(a) Enhanced polypropylene board with improved polypropylene formula and increased glass fiber content has stable chemical properties, excellent corrosion resistance, non-toxic, odorless, lightweight, strong, good toughness, and low labor intensity during manual unloading. The design of the filter plate cavity is reasonable, using a point shaped conical convex platform and a unique flow channel design. The size, arrangement, and angle of the convex points are precisely studied, which has a great impact on the filtration and dewatering volume. It achieves fast flow rate, short filtration cycle, greatly improves the working efficiency of the filter press, and increases the output by 20% compared to the old model. Keywords: service life of more than 3 years. (b) Deepen the drainage channel of the filter plate to ensure smooth flow of materials without blockage, facilitate loading and unloading of filter cloth, increase filtration speed, shorten production cycle, increase production frequency, and increase filtration volume, resulting in a significant increase in filter cake thickness to 30-35mm and yield. (c) The moisture content of the filtered mud cake is low (around 30%). Once the filter plate is opened, the filter cake will automatically detach from the filter cloth by its own weight without the need for external force. (d) The plastic elastomer diaphragm filter plate is composed of a core plate and a membrane plate, each made of different materials. The core plate is made of modified polypropylene, and the membrane plate is made of polymer PTE material. The composite of the core plate and the membrane plate is formed by one-time molding with auxiliary adhesive and grinding tools. It has the characteristics of good elasticity, good sealing performance, no water leakage, and high strength. The sealing performance between the filter plates is good. After filtration, the solid moisture content is reduced by about 5-8% compared to ordinary filter machines through air pressure pressing. The lifespan of the diaphragm is over 80000 cycles. (This diaphragm filter plate is suitable for materials that have an impact on rubber and iron)
Hydraulic system:
The hydraulic station has an open structure, and the hydraulic system completes two basic actions: the compression and opening of the oil cylinder and the pulling and removal of the oil motor, which improves the safety and reliability of the entire hydraulic system and facilitates user maintenance. The key components of the entire hydraulic station, including the oil cylinder, are products from the Sino German joint venture Wuxi Hydraulic Component Factory, while the one-way valve, directional valve, overflow valve and other hydraulic components are products from Taiwan and Shanghai Huadao Hydraulic Component Factory, making the entire hydraulic system safer and more reliable, ensuring the smooth completion of the entire filtration process for users.
(a) Hydraulic system for oil cylinder compression and release: It consists of three parts: power system, control system, and actuator. The control system consists of high-pressure relief valve, pressure gauge, one-way valve, electromagnetic directional valve, hydraulic control one-way valve, low-pressure relief valve, electric contact pressure gauge, etc. The compression pressure of the oil cylinder is adjusted by the high-pressure relief valve, and the pulling plate pressure is adjusted by the low-pressure relief valve. The pressure holding system is controlled by a one-way valve and a shut-off valve, and the oil cylinder pressure is achieved through an electromagnetic directional valve
Tightly loosen two basic actions; The electric contact pressure gauge automatically compensates for the pressure in the rear chamber (high-pressure chamber) of the oil cylinder, stabilizing the pressure within a certain range and ensuring the smooth completion of the filtration process.
(b) Hydraulic system for oil motor pulling plate and taking plate: It consists of three parts: power system (low flow plunger pump 10r/min), control system (hydraulic components), and actuator (oil motor). The control system consists of low-pressure relief valve, throttle valve, and electromagnetic directional valve. The pressure of the oil motor pulling plate is adjusted by the overflow valve (3-4Mpa); The throttle valve sets the pulling speed of the plate to maintain it within a suitable range, and the electromagnetic directional valve is used to achieve the two basic actions of the oil motor pulling and removing the plate.
electric control system：
The electronic control system adopts two types of designs: relay circuit and PLC programming, which have the characteristics of reliable performance, safety and stability. The PLC program control is operated through a human-machine interface, which is easy to learn and understand. As this system uses Siemens PLC and Mitsubishi PLC control modules, as well as low-voltage components from ABB in Sweden.
PLC has small size, strong functions, fast speed, high reliability, and due to its great flexibility and scalability, the control program can be changed according to the process, making it easy to interface with computers for remote control.

Automatic plate pulling device for filter press：
Adopting the current domestic pull plate system, the chain adopts a fully enclosed device, and the upper and lower tracks are made of stainless steel square tubes, ensuring that the chain does not rust and that there is no mud residue on the track during unloading, ensuring the normal use of the equipment.
Hydraulic opening and closing mud storage hopper for filter press——Made of 8mm thick Q235 steel plate welded together, the fan-shaped door is closed and opened by the piston rod of the hydraulic cylinder (single-sided double cylinder). The fan-shaped door is closed during unloading, and it is stored centrally for easy truck transportation. The overall mechanical strength is high, and there is no jamming during unloading and no leakage during mud storage. Good working environment and low labor intensity after use.
Control methodThe hydraulic automatic pressure holding system is used for control, and the opening and closing of the sector door is achieved through the direction change of the electromagnetic directional valve. The electronic control system adopts relay circuit control, which has the characteristics of reliable and stable performance.Product Parameters：

Automatic flipping system for filter press：
It is a liquid collection device installed under the filter plate. When the filter press is feeding, some liquid leaks under the filter plate and flows into the flip plate (automatic water collection tray) downstream to both sides of the filter press. It then flows into the centralized pool through the liquid collection tank. The main advantage is that the liquid cannot flow into the filtered solid material. For the filtration of saltwater, it saves saltwater, reduces costs, and improves efficiency. It is more advantageous for the washing solution to concentrate and flow out when washing the filter cloth, reducing the labor intensity of workers and better protecting the operating environment.
Principle of Automatic Control for Filter Press：
It is driven by a low-speed motor to flip the plate (automatic water collection tray), which is automatically opened and closed by some electrical appliances and induction switches.
