[0002] Today, with the rapid development of technology, efficient, energy-saving and environmentally friendly solid-liquid separation technology has become an essential and important process in various industries.
[0003] To meet the increasingly severe filtration tasks required by the market, it is necessary to continuously shorten the filtration time and improve the filtration effect. Therefore, increasing the pressure during the filtration process has become a key factor to quickly achieve these requirements. Although increasing the filtration pressure can greatly improve the filtration efficiency, filtration effect, processing capacity and reduce energy consumption, etc., the disadvantages are also very obvious. The basic cost of the equipment and the difficulty of later maintenance also increase accordingly. High pressure will also make the equipment run unstably, resulting in damage to the filtration medium, shortening the service life and increasing the replacement cost.
[0004] Therefore, in view of the above existing problems, this technical solution proposes a filter plate suitable for high-pressure filtration. Content of the Utility Model

[0020] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.
[0021] Please refer to Figures 1-3 , a high-pressure filtration filter plate, including a filter plate 2 and a filter cloth; the filter plate 2 is set as a rectangular structure and the filter cloth is installed in the middle of the filter plate 2. Four groups of pressure-bearing columns 3 are detachably installed at the four corners of the filter plate 2. The pressure-bearing columns 3 mainly play a role in supporting and bearing the filter plate 2. An inlet port is opened at the center of the filter plate 2, and a filter cloth clip 5 with a flow splitting groove is detachably arranged at the inlet port. One end of the filter cloth clip 5 with a flow splitting groove is connected to the edge part of the filter cloth, and the other end is connected to the inlet port area of the filter plate 2. The filter cloth clip 5 with a flow splitting groove splits the inlet liquid into each area of the filter cloth, ensuring uniform filtration process, improving the filtration efficiency, and reducing the fluid concentration in a certain part of the filter cloth through splitting, thereby reducing the risk of blockage. At the same time, the uniform fluid distribution can improve the filtration effect of the entire filter plate and ensure a higher solid particle removal rate.
[0022] In an example of the present invention, a plurality of filter cloth piles 1 are uniformly arranged at the peripheral edge of the filter plate 2. Under the action of the filter cloth piles 1, the filter cloth is stably supported and fixed on the filter plate 2 to prevent it from sliding or shifting due to fluid pressure during the filtration process;
[0023] Among them, the filter cloth pile 1 is usually fixed to the filter plate 2 by mechanical connection, generally using bolt fasteners or other fixing structures, which can ensure that the filter cloth remains stable under high pressure or high temperature environments;
[0024] While tightly fitting and fixing the filter cloth, the filter cloth pile 1 helps to improve the filtration efficiency and effect, reduce the leakage of filtrate. Good fixing can reduce the wear of the filter cloth, extend its service life, and reduce the replacement cost;
[0025] In the embodiment of the present invention, the detachable connection between the pressure-bearing column 3 and the filter plate 2 can be achieved in various ways. For example: Bolt connection: By inserting bolts into the reserved holes of the filter plate 2 and the pressure-bearing column 3 and using washers and nuts for fixation. This method has good stability and detachability, facilitating later maintenance and replacement.
[0026] Snap or clamp: Using the method of snap or clamp to quickly fix the pressure-bearing column 3 and the filter plate 2. This method is convenient for installation and disassembly and is suitable for occasions that require frequent replacement;
[0027] Among them, the pressure-bearing column 3 can help evenly distribute the pressure on the filter plate 2, preventing the filter plate 2 from deforming or being damaged due to excessive pressure during operation. At the same time, they can also provide stable structural support to ensure that the filter plate 2 maintains good sealing and filtration effect during the filtration process. In addition, the pressure-bearing column 3 can also enhance the overall strength of the filter plate, improving the operation efficiency and service life of the equipment.
[0028] As a preferred embodiment of the present invention, the filter cloth clamp 5 with a flow dividing groove includes a circular main body structure and a filter cloth fixing ring. The filter cloth fixing ring is fixed on the filter cloth by a plurality of groups of double-headed threaded pins 4 evenly distributed thereon, tightly clamping the filter cloth. At the same time, a plurality of flow dividing grooves are annularly and equally spaced on the main body structure for guiding the feed liquid to flow into different areas of the filter cloth. A plurality of internal hexagonal screw holes are annularly opened on the main body structure, and internal hexagonal countersunk head screws 6 are rotatably arranged in the internal hexagonal screw holes. Under the connection and fastening of the internal hexagonal countersunk head screws 6, the main body structure is installed outside the filter cloth fixing ring, thus forming a complete filter cloth clamp 5 with a flow dividing groove installed at the feed port.
[0029] As a preferred embodiment of the present invention, the material of the filter plate 2 is a common material such as PPH, which can be used as a substitute for the original steel filter plate 2, thereby reducing the use cost to a certain extent.
[0030] As a preferred embodiment of the present invention, multi-functional holes are opened at the four corners of the filter plate 2. Through these holes, liquid can be discharged from the four corners, and at the same time, process requirements such as filter cake washing and filtrate purging can be met.
[0031] The above describes in detail the preferred embodiments of this patent. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of this patent.
