They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0029] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0030] Example: Figures 1 to 8As shown, an ultra-high pressure filter press is mainly composed of a frame 1, a filter assembly 2, a pull plate assembly 3, a hydraulic system 5 and a control system 6. In order to make the overall structure of the filter press compact, thereby reducing the space occupied and allowing users to maximize the space utilization, in this embodiment, the filter assembly 2, the pull plate assembly 3, the hydraulic system 5 and the control system 6 are all integrated in the frame 1. The pull plate assembly 3 includes a thrust plate 3-1 and a clamping plate 3-2, and the filter assembly 2 includes a filter plate 2-1, a feed main pipe 2-2 and a feed branch pipe 2-3. A material holding cavity is formed between two adjacent filter plates 2-1. Under the action of the feed pump, the slurry enters the feed branch pipe 2-3 from the feed main pipe 2-2, and then is injected into the material holding cavity from the feed branch pipe 2-3 and the feed liquid is filtered by the pressure generated by the feed pump. Specifically, the filter plate 2-1 is disposed between the thrust plate 3-1 and the pressing plate 3-2, and the filter plate 2-1 is pressed by pressing the pressing plate 3-2 toward the thrust plate 3-1, thereby filtering the filtrate. The control system 6 is used to control the hydraulic system 5, and the hydraulic system 5 is used to drive the thrust plate 3-1 or the pressing plate 3-2.

[0031] In the existing filter press, during the filtration process, the filtrate will be filtered out through the filter cloth and drip onto the ground, causing environmental pollution and affecting the user experience, which is not conducive to the promotion and application of the above filter press in the market. In order to solve this technical problem, in this embodiment, by installing a water receiving plate assembly 4 below the above filter assembly 2, during the filtration process, the filtrate can directly drip into the water receiving plate assembly 4, which is convenient for collecting the filtrate, thereby ensuring the cleanliness and sanitation of the equipment, reducing the probability of environmental pollution, enhancing the user experience, and being conducive to the promotion and application of the above ultra-high pressure filter press in the market.

[0032] In order to ensure the stability of the water receiving plate assembly 4 during use, the water receiving plate assembly 4 in this embodiment is composed of a water receiving base 4-1 and a water receiving tank body 4-2 for storing filtrate, wherein the water receiving base 4-1 includes a flat water receiving installation plate 4-1-1, and a mounting groove 4-1-2 is formed at the center of the water receiving installation plate 4-1-1. The shape of the mounting groove 4-1-2 is adapted to the bottom shape of the water receiving tank body 4-2, and the water receiving tank body 4-2 is embedded in the mounting groove 4-1-2. The mounting groove 4-1-2 and the water receiving tank body 4-2 are usually rectangular in shape and are arranged along the length direction of the filter assembly 2, thereby reducing the probability of filtrate leakage and ensuring the cleanliness of the environment. The water receiving trough body 4-2 is funnel-shaped, that is, the upper cross-sectional area of ​​the water receiving trough body 4-2 is larger than the lower cross-sectional area, so that the water receiving trough body 4-2 can be clamped in the above-mentioned installation groove 4-1-2, so that the above-mentioned water receiving installation plate 4-1-1 can be clamped in the middle position of the height of the above-mentioned water receiving trough body 4-2, so that the distance between the opening of the above-mentioned water receiving trough body 4-2 and the above-mentioned filter assembly 2 is small, thereby reducing the probability of filtrate splashing. In order to further ensure the stability of the above-mentioned water receiving plate assembly 4 during use, and to facilitate the subsequent installation of components such as the water receiving cover plate 4-3, a limited seat 4-1-3 is formed at both ends of the above-mentioned installation groove 4-1-2, and the height of the limited seat 4-1-3 is slightly higher than the height of the water receiving cover plate 4-3. The water receiving plate assembly 4 also includes a water receiving cover plate 4-3, a cover plate bracket 4-4 and a driving unit 4-5 for driving the water receiving cover plate 4-3 to extend and retract. The water receiving cover plate 4-3 is assembled from a plurality of translation plates 4-3-1, and the water receiving cover plate 4-3 is located above the cover plate bracket 4-4. The translation plates 4-3-1 and 4-3-1 can be stacked, so that the size of the opening of the water receiving trough body 4-2 can be controlled by controlling the number of translation plates 4-3-1 opened. Specifically, the driving unit 4-5 includes a hydraulic motor, a transmission shaft, a driving sprocket and a driving chain 4-5-1. The transmission shaft is installed at the output end of the hydraulic motor, the driving sprocket is installed at the transmission shaft, and the driving chain 4-5-1 is meshed with the driving sprocket. The driving chain 4-5-1 drives the water receiving cover plate 4-3 to open and close. When the hydraulic motor rotates forward, the above-mentioned translation plate 4-3-1 can be opened; when the hydraulic motor rotates reversely, the above-mentioned translation plate 4-3-1 can be closed, or the size of the opening of the translation plate 4-3-1 can be controlled by controlling the hydraulic motor. It is specifically set according to the number of filter plates 2-1 in the above-mentioned filter assembly 2, and the main purpose is to make the size of the opening of the water receiving trough body 4-2 match the bottom area of ​​the filter plate 2-1.

[0033] The water receiving cover plate 4-3 is made of a polycarbonate sheet, that is, the translation plate 4-3-1 is made of a polycarbonate sheet. Polycarbonate (PC for short) is a thermoplastic plastic with a variety of excellent physical and chemical properties. Polycarbonate has a high degree of transparency, so that the translation plate 4-3-1 can clearly see the filtrate in the water receiving tank body 4-2 below when in use. The impact resistance of PC material is very good, and it can maintain its performance even at low temperatures, and is suitable as a cover plate that needs to withstand a certain impact.

[0034] In order to facilitate assembly, the frame 1 in this embodiment includes an upper frame 1-1 and a lower frame 1-2, both of which are hollow structures, and the filter assembly 2 is installed in the hollow part; a flat guide rail 1-3 and a limit guide rail 1-4 are installed on the top of the upper frame 1-1, and the flat guide rail 1-3 and the limit guide rail 1-4 are arranged in parallel, and the thrust plate 3-1 is installed on the flat guide rail 1-3 and the limit guide rail 1-4. By setting the flat guide rail 1-3 and the limit guide rail 1-4, on the one hand, the movement of the thrust plate 3-1 is facilitated, and the resistance during the movement is reduced; on the other hand, the wear on the frame 1 can be greatly reduced, thereby ensuring the service life of the frame 1. In order to facilitate the hoisting of the frame 1 and ensure the overall structural strength of the frame 1, the upper frame 1-1 and the lower frame 1-2 are welded and fixed.

[0035] The ultra-high pressure filter press in this embodiment adopts a dynamic pressure balance method, that is, the pressure of the oil cylinder does not reach the maximum after the mold is closed, but changes with the pressure in the filter chamber. Since the product adopts ultra-high pressure pressing, in order to reduce the risk of the oil cylinder piston's own weight crushing the oil cylinder sealing component, the filter press adopts a multi-cylinder design. In order to facilitate the installation of multiple oil cylinders and ensure the stability of the oil cylinder during use, oil cylinder mounting positions 1-5 are formed at one end of the upper frame 1-1 and the lower frame 1-2. The above-mentioned oil cylinder mounting positions 1-5 are multiple, so as to accommodate multiple oil cylinders.

[0036] The ultra-high pressure filter press of the present embodiment has an ingenious structure. By arranging a water receiving plate assembly 4 under the filter assembly 2, the filtrate can drip directly into the water receiving plate assembly 4, which is convenient for collecting the filtrate, thereby ensuring the cleanliness and hygiene of the equipment, reducing the probability of environmental pollution, enhancing the user experience, and being conducive to the promotion and application of the above-mentioned ultra-high pressure filter press in the market.
