The factory directly supplies Customizable small industrial filtration equipment, manual jack boxes and box-type filter presses.
1. No external power supply required: It is particularly suitable for use in situations without electricity, with insufficient electricity supply, or in environments with strict explosion-proof requirements, such as mines, outdoor operations, laboratories, etc.
2. Low investment cost: Without the need for complex electrical and power systems such as motors and hydraulic stations, the manufacturing cost and maintenance cost are significantly lower than those of automatic filter presses.
3. Simple operation, easy maintenance: The structure is clear and intuitive, with few fault points. Ordinary workers can operate and maintain it after receiving simple training.
4. High compression force and excellent sealing performance: The manual hydraulic jack can provide a high compression force, ensuring that the filter plate assembly does not leak during high-pressure filtration.
5. Durable and reliable: The mechanical structure is simple, with a low failure rate and a long service life.
1. Frame section:
Tail plate: Fixed in place, opposite to the pressing plate.
Main beam: Usually consists of two solid or hollow steel beams, used to support the filter plates and the pressing plates, and to bear the pressing force.
Compression plate: Pushed by the jack, it is used for compressing and releasing the filter plate assembly.
2. Filtering Section:
Filter plate: The core component, usually made of reinforced polypropylene (PP), it is corrosion-resistant and lightweight. The middle of the filter plate is a cavity, and both sides have grooves, which are used to support the filter cloth and guide the filtrate flow, jointly forming the filter chamber.
Filter cloth: The main filtering medium. Different materials and pore sizes are selected based on the characteristics of the filtered materials (such as particle size, acidity and alkalinity).
3. Pressing device:
Manual hydraulic jack: The core power unit. By manually reciprocating the jack handle, high-pressure oil is generated, pushing the piston rod out and providing a huge clamping force. This is the most fundamental difference between this model and the electric hydraulic filter press.
4. Auxiliary Components:
Collection tray: Used to collect any leaked filtrate.
Filter liquid tank: Collects the clear liquid flowing out from each filter plate.
1. Pressing the filter plate: The operator manually pumps pressure to the hydraulic jack. The piston rod of the jack pushes the pressing plate, causing multiple hollow filter plates and solid filter plates (or all filter plates with membranes) to be tightly pressed together, forming a sealed filter chamber.
2. Feed filtration: The suspended liquid (slurry) to be filtered is sent into the filter press through the feed pump (which can be an external electric or pneumatic pump). Under a certain pressure, the slurry enters each filter chamber formed by the filter plates and the filter cloth.
3. Solid-liquid separation: Under the pressure, the liquid (filtrate) penetrates through the filter cloth and gathers along the grooves on the filter plate, eventually being discharged from the filtrate outlet; while the solid particles are retained on the filter cloth surface, gradually accumulating in the filter chamber and forming a filter cake.
4. Release of discharge: Once the filtration process is completed (as indicated by the increase in feed pressure reaching the set value or a significant decrease in the liquid output), stop the feed. By releasing the pressure of the jack, the piston rod retracts, and the compression plate releases. Then, pull each filter plate one by one. The filter cake will fall off from the filter cloth due to its own weight, achieving the discharge.
5. Once a working cycle is completed: After cleaning the filter cloth and filter plates, re-press them and then the next filtration cycle can begin.
