[0029] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. 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.

[0030] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0031] The feed port of the filter plate of a traditional filter press is usually set at the top, and then the feed pipe needs to be installed on the top of the filter plate. The handle of the filter plate is often also set at the top, resulting in the feed pipe often having to pass through the handle and then connect to the feed port. In this process, the feed pipe has many elbows. The setting of the elbows undoubtedly increases the probability of pipe blockage, thereby affecting the performance of the filter plate, which is not conducive to the promotion and application of the above-mentioned filter plate in the market.

[0032] Embodiment: In order to solve the above technical problems, Figures 1 to 6As shown, a filter plate combination includes a mold partition plate 1 with a feed port 2. In order to reduce the number of elbows of the feed pipe 6, the feed port 2 is opened on the side of the mold partition plate 1 in this embodiment. The feed port 2 is used to connect the feed pipe 6, so that the feed pipe 6 can be directly bent downward to connect to a feeding device such as a feed bucket. The front and rear end surfaces of the mold partition plate 1 are respectively covered with a water-permeable layer. The water-permeable layer can be one layer or multiple layers, which is not limited here. It is mainly for filtering. The water-permeable layer located at the front and rear end surfaces of the mold partition plate 1 in this embodiment is a single layer, namely, mold water-permeable layer 1 3 and mold water-permeable layer 2 4. A material storage chamber is formed between the water-permeable layer and the front and rear end surfaces of the mold partition plate 1. The material mold water-permeable layer 1 3 and the material mold water-permeable layer 2 4 in this embodiment are both stainless steel water-permeable layers, which have a certain rigidity and can reduce the probability of deformation of the material mold water-permeable layer 1 3 due to pressure. At the same time, they have a certain supporting force to ensure that the material chamber has enough space to accommodate the material to be filtered.

[0033] In order to ensure the structural strength of the filter plate assembly as a whole and facilitate its installation on the filter press, a partition frame 5 is provided at the edge of the mold partition 1, and the mold water-permeable layer 1 3 and the mold water-permeable layer 2 4 are fixed to the mold partition 1 through the partition frame 5. Specifically, in order to facilitate disassembly and assembly, so as to inspect and maintain the filter plate assembly and thus reduce the user's use cost, the partition frame 5 in this embodiment is surrounded by a pair of opposite and spaced side frames 5-1, a pair of opposite and spaced main frames 5-2, and four mold corners 5-3, and the mold corners 5-3 are installed at the connection between the side frame 5-1 and the main frame 5-2. The connection between the mold partition 1 and the side frame 5-1, and the connection between the mold partition 1 and the main frame 5-2 are smoothly transitioned to form a drainage slope, and a drainage groove 10 is opened on the drainage slope. The drainage groove 10 in this embodiment is located below the mold partition 1. The gently transitioning drainage slope can improve the drainage efficiency. Through the gradual transition of the slope, the water flow can flow more smoothly, reducing the possibility of water accumulation and stagnation. The drainage groove 10 can effectively collect and guide the water flow, thereby accelerating the drainage speed.

[0034] In order to control the feeding speed of the material and ensure the uniformity of the feeding, in this embodiment, a feed block 7 is installed at the feed port 2 of the material mold partition. In order to ensure the sealing and prevent the device from entering the above-mentioned material storage chamber, the edge of the above-mentioned feed block 7 and the above-mentioned material mold partition 1 are sealed and connected by welding or glue. The feed block 7 can also prevent the material in the feed pipe 6 from directly entering the material storage chamber, thereby reducing the probability of blockage at the opening of the material storage chamber. A through hole 7-1 is provided on the surface of the above-mentioned feed block 7, and a feed hole 7-2 is provided on the side of the above-mentioned feed block 7. The above-mentioned feed hole 7-2 is perpendicular to the above-mentioned through hole 7-1 and is connected. The above-mentioned through hole 7-1 can be used to detect whether the feed port is blocked, which is convenient for users to inspect and maintain it.

[0035] In order to prevent impurities from entering the material storage chamber, a feed flap 8 is installed at the opening of the through hole 7-1. The feed flap 8 can be connected to the feed block 7 through a rotating shaft, that is, a shaft sleeve is provided on the feed block 7, and a rotating shaft adapted to the shaft sleeve is provided on the feed flap 8. The feed flap 8 can be opened and closed by inserting the rotating shaft into the shaft sleeve. A filter cloth pressure cover 9 is installed below the feed flap 8. The filter cloth pressure cover 9 is used to fix the filter cloth and keep it tightly fitted below the feed flap 8. By installing the filter cloth pressure cover 9, the filter cloth can be effectively prevented from shifting or loosening during use, ensuring that the filter cloth can completely cover the through hole 7-1, preventing impurities and particles from entering the interior. The filter cloth pressure cover 9 can also provide a certain pressure to form a tight seal between the filter cloth and the feed flap 8, preventing the material from leaking out from the middle or leaking, thereby ensuring that the material is effectively filtered and separated by the filter cloth during the feeding process, and improving the purity and quality of the product. In order to install and fix the filter cloth gland 9, the feed block 7 is formed with a filter cloth gland groove 7-3, which can ensure that the filter cloth can be firmly covered on the feed block 7. The filter cloth gland groove 7-3 provides a specific position and structure, so that the filter cloth can be easily installed on the feed block 7 and maintain close contact with the feed block 7. By correctly installing the filter cloth gland groove 7-3, the filter cloth can be prevented from loosening or shifting, ensuring that the filter cloth can effectively filter the material and prevent impurities and particles from entering the interior. In addition, the filter cloth gland groove 7-3 can also provide certain protection to prevent the filter cloth from being damaged or worn, thereby extending the service life of the filter cloth. The depth of the filter cloth gland groove 7-3 is compatible with the thickness of the filter cloth gland 9, and the central axis of the filter cloth gland groove 7-3 is located on the same straight line as the central axis of the through hole 7-1. The filter cloth gland 9 is a hollow structure and a reinforcing rib 9-1 is formed in the hollow part. The reinforcing rib 9-1 is multiple and arranged in a star-shaped structure, i.e., equidistantly distributed along the central axis of the filter cloth gland 9, which can effectively prevent the diaphragm from being siphoned during squeezing, thereby ensuring the filtering effect. In order to facilitate the installation of the filter cloth gland 9, a mounting hole 9-2 is provided, and the mounting hole 9-2 is a countersunk hole. A connecting hole 7-4 matching the mounting hole 9-2 is formed in the filter cloth gland groove 7-3.

[0036] A plurality of filter plate bosses 11 are provided on both sides of the mold partition 1, and the filter plate bosses 11 are evenly distributed on both sides of the mold partition 1. In terms of structure, the filter plate bosses 11 are protruded outward from both sides of the mold partition 1, and the height of the filter plate bosses 11 is slightly lower than the partition frame 5. The arrangement of the filter plate bosses 11 allows the force load of part of the partition frame 5 to be shared during the filtration pressure, so that the overall force of the filter plate is more even.

[0037] A filter plate combination in the present embodiment has an ingenious structure. The feed port 2 is set on the side of the material mold partition plate 1, and the feed pipe 6 is connected to the feed port 2, so that the feed pipe 6 does not need to pass through the handle when installed, that is, it can be directly bent downward. While reducing the elbows of the feed pipe 6, it also reduces the probability of pipe blockage, ensures the performance and service life of the filter plate, enhances the user experience, and is conducive to the promotion and application of the above-mentioned filter plate combination in the market.

[0038] A filter plate combination in this embodiment can be applied to, including but not limited to, a filter press, so that the filter press also has the advantages of improving the original problems of many elbows in the feed pipe and filter plate blockage, thereby ensuring the performance and service life of the filter plate.
