Factory-made 630 manual hydraulic cylinder box-type filter press We can provide customized liquid filtration solutions.
Core structure composition:
1. Rack section: The main framework composed of thrust plates, compression plates and main beams (made of steel), which bears all the filter plates and compression forces.
2. Manual hydraulic system: This is the distinctive feature of this equipment. It includes:
- Manual hydraulic pump: The operator provides pressure oil to the system by turning the handle.
- Hydraulic cylinder: Receives hydraulic pressure, generates a powerful thrust, and pushes the clamping plate to tightly compress all the filter plates.
- Pressure gauge: Displays the current clamping pressure to prevent overpressure or insufficient clamping.
- Overflow valve (safety valve): Sets the maximum pressure to ensure the safety of the equipment.
3. Filtering Section:
Filter plate: Made of reinforced polypropylene (PP) or rubber, cast iron, etc., with an empty center, used to hold the filter cake. The two sides of the filter plate are wrapped with:
Filter cloth: As the filtering medium, different materials and pore sizes are selected based on the characteristics of the materials to be filtered, which is the key to achieving solid-liquid separation.
1. Compression:
The operator rotates the handle of the manual hydraulic pump to press the hydraulic oil into the cylinder, causing the compression plate to move forward and compress all the filter plates between the thrust plate and the compression plate, thus forming a sealed filter chamber.
2. Feed filtration:
The material is pumped into each filter chamber through the feed port on the thrust plate. Under the action of the feed pressure, the liquid (filtrate) penetrates through the filter cloth and flows out of the machine along the grooves on the filter plate (open flow) or collects in the main pipe and flows out (closed flow); the solid particles are retained in the filter chamber and gradually form a filter cake.
3. Discharge:
When the filtration pressure reaches the set value or the filter chamber is filled, stop the feeding. The operator manually releases the hydraulic valve to relieve the pressure, and then manually pulls out each filter plate one by one. The filter cake falls off due to its own weight, completing one working cycle.
1. Economical and practical: No need to install expensive electric pumping stations or PLC control systems. The equipment purchase cost and long-term maintenance cost are extremely low.
2. Simple operation: No complex training is required. Operators can easily complete the pressing and releasing actions by using the manual pump.
3. Strong adaptability: Particularly suitable for scenarios without power supply or with unstable power (such as remote mining areas, temporary work sites). Also applicable to the filtration of small quantities and multiple types of materials.
4. Energy conservation and environmental protection: The pressing process is entirely carried out manually and does not consume electricity.
5. Stable structure: As the basic model, the mechanical structure is mature and reliable, with a low failure rate.
This model is suitable for scenarios where the requirement for automation is not high, but reliable solid-liquid separation performance is needed, such as:
1. Chemical industry
Filtration of dyes, pigments, intermediates, titanium dioxide, ceramic glazes, etc.
2. Environmental protection industry
Small-scale sewage treatment stations, sludge dewatering in laboratories.
3. Mining
Concentration of ore slurries in small-scale mineral processing plants, and dewatering of tailings.
4. Food industry
Filtration of edible oil, fruit juice, and sugar solutions.
