[0002] A filter press is a general-purpose mechanical device used for solid-liquid separation, employing physical methods to separate solid-liquid mixtures. Based on the method of filter cake formation, it can be divided into box-type filter presses and plate-and-frame filter presses. A plate-and-frame filter press consists of a filter plate and a filter frame as its filtration unit; a single filter press comprises multiple filtration units arranged sequentially, with the filter cake forming within the filter frame. When filtering high-viscosity liquids, pressure filtration is required, but existing filter plates have relatively low strength and are prone to deformation and damage. Summary of the Invention

[0009] Preferably, the pressure frame is made of a corrosion-resistant material.
[0010] The beneficial effects of this utility model are: 1. This utility model has an outer frame made of high-strength aluminum alloy and a filter plate made of aluminum alloy honeycomb panel. The filter plate has high strength and is not easily deformed when supporting the filter cloth under high pressure filtration conditions, thus meeting the requirements of high pressure filtration.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.
[0016] like Figs. 1 to 4 As shown, this embodiment provides a high-strength, deformation-resistant filter press structure, including an outer frame 1 made of high-strength aluminum alloy, the surface of which is coated with a corrosion-resistant layer, and a filter plate 2 made of aluminum alloy honeycomb panel. The outer frame 1 is provided with an installation port 3 for installing the filter plate 2, and the filter plate 2 and the outer frame 1 are fully welded together. Rubber plates 4 are installed on both sides of the filter plate 2, and the rubber plates 4 are provided with inwardly recessed drainage grooves 5. The rubber plates are provided with water guiding grooves 6 communicating with the drainage grooves. The outer frame 1 is provided with a drain pipe 7 connected to the water guiding grooves 6. Filter cloth 8 is fixed on the surface of the rubber plates 4, and the outer frame 1 is provided with a liquid inlet pipe 9 located outside the filter cloth 8.
[0017] The outer frame 1 is made of high-strength aluminum alloy, and the filter plate 2 is made of aluminum alloy honeycomb panel. The filter plate 2 has high strength and is not easily deformed when supporting the filter cloth 8 under high pressure filtration working environment, which meets the working conditions of high pressure filtration. Rubber plates 4 are installed on both sides of the filter plate 2 to avoid contact with the filter plate 2 and easy corrosion of the filter plate 2.
[0018] The filter plate 2 has multiple threaded posts 10 installed on its peripheral edge. The rubber plate 4 has through holes 11 corresponding to the threaded posts 10. The filter cloth 8 also has through holes 12 corresponding to the threaded posts 10 on its peripheral edge. The rubber plate 4 is fitted with a pressure frame 13 to press the peripheral edge of the filter cloth. The pressure frame 13 has mounting holes corresponding to the threaded posts 10. The threaded posts 10 pass through the through holes 11, through holes 12, and mounting holes to be fitted with locking nuts 15. This utility model uses the pressure frame 13 for pressing and fixing, which provides a good positioning effect for the filter cloth 8. Rubber sealing rings 16 are provided between the filter cloth 8 and the rubber plate 4, and between the filter cloth 8 and the pressure frame 13, which provides a good sealing effect during fixing. In the high-pressure filtration working environment, leakage is not likely to occur, and it is convenient to replace the worn rubber plate 4. Furthermore, the rubber plate and the pressure frame are fixed by the threaded posts 10 and locking nuts 15, which facilitates assembly and disassembly.
[0019] Rubber sealing rings 16 are provided between the filter cloth 8 and the rubber plate 4, and between the filter cloth 8 and the pressure frame 13. Each rubber sealing ring 16 also has a limiting hole 17 for the threaded post 10 to pass through. After fixing, it provides a good sealing effect and is less prone to leakage under high-pressure filtration conditions. It also facilitates the replacement of worn rubber plates 4. The top of the threaded post 10 does not protrude beyond the mounting opening, thus avoiding any adverse interference with the connection of the filter press plates. The pressure frame 13 is made of corrosion-resistant material and has strong corrosion resistance.
[0020] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0021] The working principle is as follows: the outer frame 1 is made of high-strength aluminum alloy and the surface of the outer frame 1 is coated with a corrosion-resistant layer. The filter plate 2 is made of aluminum alloy honeycomb panel, so the filter plate 2 has high strength. When supporting the filter cloth 8, the filter plate 2 is not easily deformed under the working environment of high pressure filtration, which meets the working conditions of high pressure filtration. Rubber plates 4 are installed on both sides of the filter plate 2 to avoid contact with the filter plate 2 and easy corrosion of the filter plate 2.
[0022] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
