High cost-performance solution for sludge dewatering - Factory customized 630 type dark flow chamber filter press - Automatic hydraulic/manual plate pulling

1. Automatic hydraulic system
Function: It is used to compress all the filter plates, forming a sealed filter chamber and providing continuous pressure during the filtration process. 
Feature:

Automated operation: Through the hydraulic station and the electronic control system, the filter plates can be automatically compressed and released, significantly reducing the labor intensity of workers and improving the efficiency of the filtration process. 
Pressure stability: The hydraulic system can provide a strong and uniform clamping force, ensuring that the filter chamber does not leak under high pressure and guaranteeing the filtering effect. 
Safe and reliable: Equipped with an electric contact pressure gauge and an overflow valve, it can set and automatically control the clamping pressure. In case of overpressure, it will automatically release the pressure to protect the equipment and the operators' safety. 

2. Manual lifting of the panel
Function: After the filtration process is completed, slowly pull out each filter plate one by one to remove the filter cake. 
Feature:

Simple structure, low cost: Compared with the automatic plate-lifting system, it eliminates the complex transmission and control systems, resulting in lower equipment manufacturing costs and subsequent maintenance costs. 
Maintenance convenience: The mechanical structure is simple, with a low failure rate. Even if there are minor issues, they can be easily identified and repaired. 
High flexibility: Operators can adjust the force and speed of the pull plate according to the adhesion condition of the filter cake. This feature is particularly advantageous for certain special materials (such as filter cakes that are easily broken or highly viscous). 
Disadvantage: Requires manual operation, and the labor intensity is slightly higher compared to the automatic plate pulling method. 

3. Secreted fluid in the dark
Function: The method for discharging the filtrate (the separated liquid). 
Feature:

High environmental friendliness: All the filtrate flows through the internal channels of the filter plate and is collected at the total outlet pipe at the tail of the filter press for unified discharge. The entire process is in a closed state, effectively preventing toxic, harmful, odorous or volatile filtrate from leaking out, thus protecting the working environment. 
Clean and attractive: It avoids the problem of liquid leakage in the open flow method, keeping the equipment and the surrounding area clean and tidy. 
For subsequent processing: The centralized liquid outlet is convenient for connecting pipes and enables the unified collection or subsequent treatment of the filtrate. 

4. PP Polypropylene Filter Plate
Function: The core component that constitutes the filtering unit. 
Feature:

Excellent corrosion resistance: It has outstanding resistance to various chemical substances such as acids, alkalis, and salts, and has a wide range of applications. 
Light weight: Compared to cast iron filter plates, PP filter plates are much lighter in weight, making them easy to be transported and installed manually. They are particularly suitable for manual pulling plate types. 
Non-toxic and odorless: Meets the hygiene standards for industries such as food and medicine. 
Good resilience: Possesses certain resistance to impact and deformation. 
High cost-effectiveness: Excellent comprehensive performance, moderate price, and it is one of the most widely used filter plate materials.
