 1. Process layout diagram of vertical filter press system    
       

The process system of the vertical filter press mainly includes several parts, including the feeding system, pneumatic control system, filter cloth cleaning system, pipeline system, extrusion water system, host and electro-hydraulic control system. In order to focus on operation and maintenance of the workshop environment, the system equipment is usually arranged in two layers: the upper layer houses the vertical filter press host, hydraulic system, and electrical control system, while the lower layer houses the feeding system, pneumatic control system, filter cloth cleaning system, extrusion water system, and pipeline system, achieving dry and wet separation of the equipment and effectively extending its service life.

2.working principle
        BLZG series vertical filter press is controlled by PLC. The filtration method adopts single-side filtration, single-side extrusion and double-side discharge. It mainly realizes 6 processes: static pressure filtration, primary diaphragm extrusion, filter cake washing, Secondary diaphragm extrusion, filter cake drying, filter cake discharge and filter cloth washing.

(1) Working principles
         Filter stage: when the filter plate frame closed and sealed,the slurry enter into each filter cavity visa slurry piping. Under the effect of static pressure of feed pump, filtrate enters into filtrate pipe visa filter cloth. The solid body is held back in filter cavity by filter cloth.
(2)Diaphragm extruding 1
         Once extruding: high pressure water(high pressureair) enter into the diaphragm above visa hosepipe, diaphragm extruding filtercake to  the surface orientation of filter cloth, the filter cloth changes is thinner and extrude the remained filtrate out of filter cake.

 

(3)Filter cake washing
        Washing(option stage): use the same method with slurry, the  washing liquid is transmitted to filter cavity by pump, due to that  washing liquid filled in filter cavity, diaphragm is raised, washing liquid inflow into filtrate pipe visa filter cake and filter cloth under the pressure of pump.
(4)Diaphragm extruding II
    Twice extruding(optional stage): after washing stage, the washing liquid left in filter cavity will be extruded from filter cake by the method in the second
stage, and realize displacement washing function.

(5)High press air passes filter cake for drying
Air drying: The compressed air entered into filter cavity takes away the moisture left in the filter cake particles, reduces the moisture content of filter cake       
to the optimum degree, at the same time, to empty the filtrate in filter cavity.
(6)Automatically filter cake unloading and automatically filter cloth washing
       Discharge of filter cake: When the drying process is completed,the plate and frame components are opened, the filter cloth driving mechanism starts to run,
and the filter cake on the filter cloth is automatically discharged from both sides of  the filter press, while the washing water strongly wash the filter cloth through the high-pressure nozzle.

3.Vertical filter press technical features
    (1)Each filter chamber grouting separately ensures that all the filters are fed synchronously. The pressure of the filter plate is uniform, the time of filling the filter chamber with slurry is short, and the filtering speed is much better than that of the fast-opening filter with central feeding (single-end or double-end).
     (2)Up to 1.6MPa diaphragm extrusion force and advanced filter cake section high pressure blow drying dehydration drying technology,  more suitable for the filtration of fine particulate materials and viscous materials, which can greatly reduce the moisture content of filter cake, thus shorten the thermal drying time of filter cake, reduce energy consumption and transportation costs.
    (3)The horizontal placement of the filter plate and the filter cake replacement washing can minimize the consumption of washing water and effectively improve the washing efficiency, product recovery rate and product quality.
   (4)It can realize 100% automatic continuous operation, greatly reduce the number of employees, ensure the best production process effect, and provide users with a healthy, safe, environmentally friendly and civilized production environment.
   (5)All the filter plates are pulled open at one time, the filter cloth drives walking, and the two ends of the filter cloth are automatically unloaded. At the same time, the filter cloth is cleaned by double-sided and multi-point high pressure. The regeneration effect of the filter cloth is good, the maintenance and replacement are convenient, and the operation cost is low.
    (6)Using PLC + touch screen automatic control technology, it can display valve switch status, inquire history record, fault alarm and modify process parameters online. It has high sensitivity, safety, reliability and easy operation.
    (7)Vertical structure, single station treatment capacity is large and reduces the needed quantities and the covered area of equipments.
4.BLZG series vertical filter press technology innovation
      Luzhong companyBLZG series vertical filter press has a number of independent intellectual property rights, and has the following innovation point compared with domestic and foreign products:
    (1)The world's first four-cylindrical beam frame structure (protected by patent), the cylindrical beam is forged as a whole, which is more rigid than the plate beam frame structure. Especially in the overall sealing effect and stability of vertical filter press, the cylindrical beam frame structure is far superior to the plate beam structure.
     (2)The cylindrical beam has synchronous guiding effect on the fast oil cylinder, which avoids the lateral shearing force of the fast oil cylinder piston rod.Compared with other structures, the force on the oil cylinder is more reasonable and the service life is longer.
    (3)The filter plate seal adopts hydraulic pressure plate automatic compensation seal (protected by patent), and the cylinder pressure (sealing force) is automatically adjusted with the feed pressure, which effectively improves the service life of the filter cloth and the seal ring.
    (4)The upper platen lock adopts the automatic card key device (protected by patent), which is larger than the force contact surface of the pin device, and does not cause the pin shaft indentation, the bending, the insertion and removal of the pin shaft, etc., and the service life is long, safe and reliable.
   (5)The photoelectric double cylinder automatic correcting device (protected by patent) detects the deviation of the filter cloth by the photoelectric switch, and the double cylinder drives the correcting roller to swing, and realizes the automatic correction of the filter cloth; the deviation correction control is independent from the hydraulic system, and is not subject to the pressure of the hydraulic system, the effects of flow and temperature. stable operation, accurate control and easy maintenance.
     (6)Optimize the filter cloth cleaning method, use double-sided multi-point high-pressure cleaning filter cloth, filter cloth regeneration effect is good
     (7)Using pulse sensing technology, intelligently find the seam position of the filter cloth, realize the accurate positioning of the filter cloth joints and stop the joints from stopping in the frame.
    (8)In order to meet the requirements of materials and process, our company can provide various materials and models of filter plates and diaphragms.
