[0002] Silica gel is a type of amorphous silicon dioxide that is widely used at this stage. It is generally obtained by processing silicon dioxide solution. In order to ensure the quality of the final product, it needs to be filtered.

[0003] Conventional plate-type melt filters are used in silica gel filtration, accommodating high pressures, increasing production output, and enabling rapid screen changes. However, their metal-to-metal seal structure causes friction, squeezing, and carbonization of the silica gel between the metals. This can then enter the system during screen changes, resulting in substandard product. Summary of the Invention

[0019] The present invention is further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0020] like Figure 1-3As shown, a silica gel filtering device includes a fixed feed plate 1, a fixed discharge plate 2 and a telescopic tube 3 located between the fixed feed plate and the fixed discharge plate; a filtering structure 4 is provided between the fixed feed plate, the fixed discharge plate and the telescopic tube, and the fixed feed plate and the fixed discharge plate are respectively provided with a feed port and a discharge port facing the telescopic tube; and also includes two movable structures for driving the filter frame to move.

[0021] In this way, the fixed feed plate, the fixed discharge plate and the movable structure are fixedly installed on the frame, the fixed feed plate is connected to the feed pipe, and the fixed discharge plate is connected to the feed port of the equipment. After the raw materials pass through the feed port of the fixed feed plate, they pass through the filtering structure and the telescopic tube, and finally reach the equipment through the discharge port of the fixed discharge plate. The equipment heats and pressurizes the raw materials to obtain the finished product.

[0022] The two filter structures can achieve two-stage filtration, and when the filter structure needs to be disassembled for cleaning, the telescopic tube can be used for quick disassembly.

[0023] During implementation, the filtering structure includes a filter frame 5 and a filter screen 6. A sink is provided at one end of the filter frame close to the telescopic tube. A reinforcement frame is fixed to the periphery of the filter screen. The reinforcement frame is fixed in the sink by screws.

[0024] In this way, the mesh size of the filter is selected according to the required filtering accuracy, and the installation of the filter is made more stable by setting the reinforcement frame.

[0025] During implementation, the telescopic tube includes an outer tube 11 and an inner tube 12. One end of the outer tube is provided with a lower convex edge 13, and one end of the inner tube is fixed with an upper convex edge 14, the upper convex edge and the lower convex edge overlap, the end of the outer tube not provided with the lower convex edge protrudes outward and is provided with an outer convex edge 15, and the end of the inner tube not provided with the upper convex edge protrudes outward and is provided with an inner convex edge 16;

[0026] It also includes two columns 17, on both sides of which an outer hydraulic cylinder 18 and an inner hydraulic cylinder 19 are fixedly installed. The end of the cylinder rod of the outer hydraulic cylinder is fixedly connected to the outer convex edge, and the end of the cylinder rod of the inner hydraulic cylinder is fixedly connected to the inner convex edge.

[0027] In this way, the telescopic tube arrangement enables relative sliding of the outer and inner tubes, with the upper and lower convex edges providing a limit position to prevent the telescopic tubes from disengaging. During use, the outer and inner hydraulic cylinders respectively drive the outer and inner tubes to slide outward and away from each other, with the outer and inner convex edges pressing the filter frame against the fixed feed and discharge plates, securing the filter structure. When disassembly is required, the outer and inner hydraulic cylinders drive the outer and inner tubes toward each other, releasing the pressure on the filter structure. The movable structure then drives the filter structure to move and remove it.

[0028] During implementation, rubber pads are fixed on both sides of the filter frame to improve the sealing effect.

[0029] During implementation, a rubber pad is fixed to the sinking platform facing the reinforcement frame to improve the sealing effect.

[0030] During implementation, the upper convex edge is fixedly connected to the inner tube by screws, which is convenient for installation.

[0031] During implementation, the mobile structure includes a mobile hydraulic cylinder 21, the cylinder rod of the mobile hydraulic cylinder is fixedly installed with a mobile frame 22, the mobile frame is U-shaped, and brackets 23 are fixedly installed on both sides of the opening of the mobile frame. The bracket is U-shaped, and a sliding rod 24 is fixed in the bracket. Sliders 25 are fixed at both ends of the filter frame, and the slider is provided with a sliding hole that slides with the sliding rod. A compression spring 26 is sleeved on the sliding rod, and the compression spring is located on the side of the slider away from the telescopic tube.

[0032] During disassembly, the compression spring pushes the filter frame to slide when the telescopic tube contracts, disengaging it from the fixed feed and discharge plates. The hydraulic cylinder then retracts, driving the movable frame and bracket to move, allowing the filter frame to move outward. This prevents wear and tear between the filter frame and the fixed feed and discharge plates when the filter frame is removed, significantly extending its service life.

[0033] Specifically, during installation, the fixed feed plate and the fixed discharge plate are fixedly connected to the equipment respectively, and the column and the mobile hydraulic cylinder are fixedly installed on the equipment to provide an installation foundation.

[0034] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
