The full-automatic filter press detects the working pressure of the main oil passage of the current pull plate hydraulic transmission system according to the intelligent transmitter, and converts the working pressure data signal of its cognitive ability into analog input that PLC can distinguish, thus controlling the pull plate forward and backward. The set proximity switch allows the pull board system software to be immediately interrupted/repaired during the entire process of pulling the board or the entire process of all system operations, making the operation steps more user-friendly.
The components of the automatic filter press are:
1. lifting polypropylene pp board
1. The polypropylene pp board is improved by improving the polypropylene pp formula and improving the composition of glass fiber. It has stable analytical chemical characteristics, high-quality corrosion resistance, no toxicity, no smell, light net weight, high tensile strength, good plasticity, low labor productivity and durability when feeding human resources. The design of the filter plate concave mold of the filter press is reasonable, the patch cone mold seat is adopted, the design of the flow channel scheme is unusual, the protruding point specification, the arrangement is thin and dense, the angle and so on are carried out for precision processing scientific research, which does great harm to the total flow of filtration and dedrying, ensures fast water output, short filtration cycle, and further improves the working efficiency of the belt filter press.
2. Intensifying the stainless steel drain tank of the filter plate of the filter press, making the raw materials easy to block, handling and loading the filter cloth of the filter press convenient and quick, increasing the filtering speed, reducing the production cycle, increasing the number of production and processing times, and expanding the filtering volume, increasing the thickness of the filter cake to 30mm, and significantly increasing the total output.
3. The water content of the filtered sludge is low. Once the filter plate of the filter press is opened, the anaerobic granular sludge will automatically solve the filter cloth of the filter press by virtue of its own net weight without external force.
2. hydraulic transmission system
The hydraulic transmission system is of vertical structure. The hydraulic transmission system can automatically test the pressure in two most postures of hydraulic cylinder tightening and loosening, which improves the safety performance and reliability of all hydraulic transmission systems. In addition, it is convenient for customers to repair and maintain. The main electronic components of all hydraulic transmission systems: the hydraulic cylinder adopts the products of Wuxi Hydraulic Transmission System Factory, a Sino-Russian Sino-foreign joint venture, thus making all hydraulic transmission systems more trustworthy, ensure the smooth completion of all filtering processes for customers.
1. The hydraulic cylinder is tightened and loosened. The hydraulic transmission system: it is composed of three parts: power system, control system, and implementation electronic devices. The control system is composed of high-pressure overflow valve, pressure gauge, this product, electro-hydraulic reversing valve, hydraulic check valve, high-pressure overflow valve, electric contact pressure gauge, etc. The clamping working pressure of hydraulic cylinder is controlled by high pressure relief valve accuracy, the working pressure of pull plate is controlled by bottom pressure relief valve accuracy, the pressure test system is controlled by this equipment and stop valve, and the hydraulic cylinder is tightened and loosened according to electro-hydraulic reversing valve. The electric contact pressure gauge automatically pressurizes the working pressure of the rear cavity of the hydraulic cylinder to stabilize the working pressure within a range and ensure the smooth completion of the whole filtration process.
