Sealing rings are fitted into the through holes of the infeed and outlet plates, located on both sides of the sliding plate and sealingly contacting its surface. The purpose of this utility model is to provide a plate-type silicone filter: the main structure of this filter is made of stainless steel, the sealing structure uses PTFE sealing, the outlet plate has added slide rails, the filter sliding plate moves on the slide rails, the silicone entering from the infeed plate exerts pressure on the sliding plate, the slide rails reduce frictional resistance during screen changing, and a hydraulic or motor reducer system can easily push and pull the sliding plate.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-7 .

[0032] To address the problems of slow filtration speed and low filtration efficiency of silicone raw materials in existing technologies, the inconvenience of disassembling and cleaning the filter screen after use, and the tendency of the filter screen to clog during long-term use, this solution provides a silicone compound filter. The filter comprises a filter cylinder 1 and a filter box 9 inserted into the lower end of the filter cylinder 1. A pressing assembly is located at the upper end of the filter cylinder 1 and includes an electric telescopic rod 3 fixedly installed at the upper end of the filter cylinder 1, a movable pressure plate 4 fixedly connected to the output end of the electric telescopic rod 3, and a vertical rod 5 for limiting movement. The pressing assembly extrudes the silicone raw material downwards for filtration. Fixing mechanisms are provided at both ends of the front side of the filter box 9, which enable the filter box 9 to be disassembled within the filter cylinder 1.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the filter cylinder 1 is placed on the ground by the support frame 2. The upper end of the filter cylinder 1 is equipped with a pressing component, and the front side of the movable pressing plate 4 is equipped with a feeding component. The silica raw material to be filtered is added into the filter cylinder 1 through the feeding hopper 6 and the through hole on the front side of the movable pressing plate 4. After feeding, the cover plate 7 is locked onto the upper end of the feeding hopper 6, and then the fixing bolt 8 is rotated to limit the distance between the cover plate 7 and the feeding hopper 6. The silica raw material in the filter cylinder 1 is filtered through the filter box 9. After filtration, it can be discharged outward and collected at the bottom of the filter cylinder 1. During the filtration process, the electric telescopic rod 3 installed on the upper end of the filter cylinder 1 is activated. The electric telescopic rod 3 pushes the movable pressing plate 4 to move slowly downward. The movable pressing plate 4 drives the vertical rod 5 to slide between the filter cylinder 1, thereby improving the stability of the movable pressing plate 4 moving inside the filter cylinder 1. By moving the movable pressing plate 4 downward, pressure is increased in the filter cylinder 1. At this time, the silica raw material in the filter cylinder 1 can be quickly filtered through the filter box 9, improving the filtration efficiency of the silica raw material.

[0034] After the filtering is complete, such as Figure 5 , Figure 6 and Figure 7As shown, a sealing gasket 10 is fitted between the front side of the filter box 9 and the filter cylinder 1. Fixing mechanisms are provided at both ends of the front side of the filter box 9. Each fixing mechanism includes a hinged movable stop post 12 connected to the front side of the filter cylinder 1, a spring 13 inside the movable stop post 12, a fixing pin 14 connected to the movable end of the spring 13, a fixing rod 15 fixed to the front end of the fixing pin 14, and a fixing post 16 fixed to the lower front side of the filter cylinder 1. By pulling the fixing rod 15 upwards, the fixing rod 15 causes the fixing pin 14 to slide within the movable stop post 12. 4. The spring 13 is compressed, causing it to deform elastically. At this time, the lower end of the fixing pin 14 moves out of the fixing post 16, thereby releasing the limit on the movable stop post 12. Then, the movable stop post 12 is flipped and rotates in front of the filter cylinder 1, disengaging from the filter box 9 and releasing the limit between the filter box 9 and the filter cylinder 1. Then, the fixing handle 11 at the front end of the filter box 9 is pulled to remove the filter box 9 from the filter cylinder 1, thus facilitating the disassembly and cleaning of the filter box 9 and preventing the filter box 9 from becoming clogged during long-term use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
