Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a quick-opening filter press which is convenient for unloading. Background Art

[0002] The filter press uses a special filter medium to apply a certain pressure to the object to make the liquid seep out. It is a kind of mechanical equipment commonly used for solid-liquid separation equipment. It is mainly used in environmental protection industries such as medicine, chemical industry, standard parts, pharmaceuticals, metallurgy, non-standard screws, dyes, food, brewing, ceramics, oil refining, sewage treatment, etc. The common filter press on the market uses a special filter medium to apply a certain pressure to the object to be filtered, so that the liquid seeps out. It is a kind of mechanical equipment commonly used for solid-liquid separation equipment. Among them, the filter press includes multiple concave parts (cavities) of adjacent filter plates sandwiching filter cloths to form multiple filter chambers. When removing the filter cake, the filter plates need to be pulled apart one by one by using the pulling plate mechanism, which makes the pulling plate unloading time of the filter press account for a large part of the operating cycle time, greatly reducing the working efficiency of the filter press.

[0003] A plate and frame filter press disclosed in the Chinese utility model patent application disclosure specification CN211987279U, although the utility model can improve the adaptability of the filter press, cope with the different temperature requirements of the filtered materials, and make full use of energy, but when the filter plates need to be pulled apart to remove the filter cake, since the filter plates are connected by a connecting chain and pulled apart one by one by a pulling mechanism, this makes the process of pulling the filter plates apart take a long time, which reduces the production efficiency. Therefore, there is a problem that it takes a long time to pull the filter plates apart one by one, and after the filter cake is removed, some residues will stick to the filter plates and cause blockage, which reduces the filtration efficiency. Therefore, there is a problem that the filter cake residues stick to the filter plates. In summary, the utility model has the problems that it takes a long time to pull the filter plates apart one by one and there are filter cake residues sticking to the filter plates.

[0027] A second electric telescopic rod 10 is fixedly connected to the front right side of the frame 7, the outer side surface of the right part of the piston rod of the second electric telescopic rod 10 in the left direction is movably connected to the frame 7, the left end of the piston rod of the second electric telescopic rod 10 in the left direction is fixedly connected to a paddle 14, the left side of the front side of the filter plate 15 is fixedly connected to the paddle 14, the front side of the paddle 14 abuts against a baffle 12, the bottom of the paddle 14 abuts against the frame 7, the front bottoms of the two paddles 14 are connected by a connecting chain 22, the lower inner side surface of the baffle 12 is movably connected to a fixed rod 29, the outer side surface of the fixed rod 29 is sleeved with a torsion spring 28, one end of the torsion spring 28 is fixedly connected to the baffle 12, and the other end of the torsion spring 28 is connected to the fixed rod 29 The fixed connection is that the front side surface of the frame 7 is fixedly connected with the fixed frame 13, and the inner side surface of the fixed frame 13 is movably connected with the blocking column 19, and the upper part of the blocking column 19 abuts against the blocking piece 12. The upper part of the front and rear sides of the inner wall of the fixed frame 13 is provided with a fourth sliding groove 27, and the inner side surface of the fourth sliding groove 27 is slidably connected with the second sliding block 26, and the side surface of the second sliding block 26 close to the blocking piece 12 is fixedly connected with the fixed rod 29, and the front and rear sides of the blocking piece 12 abut against the fixed frame 13. By setting a connecting chain 22, two adjacent paddles 14 are connected, so that the second electric telescopic rod 10 can continue to pull the subsequent paddles 14 after pulling the first paddle 14, and there is no need to waste time by continuously pulling open the filter plates 15 one by one.

[0028] When in use, after the hydraulic cylinder 8 has squeezed the filter plate 15 through the squeezing plate 6, the hydraulic cylinder 8 is started to drive the squeezing plate 6 to move to the right to the far right, and then the second electric telescopic rod 10 is started to pull the first paddle 14 on the right, and the paddle 14 pushes the baffle 12 to rotate around the fixed rod 29. At this time, the torsion spring 28 is deformed. When the paddle 14 continues to move to the right and separates from the baffle 12, the torsion spring 28 is elastically deformed, so that the baffle 12 rotates around the fixed rod 29 to return to its original position. As the paddle 14 is continuously pulled, the connecting chain 22 is gradually straightened. At the same time, the paddle 14 drives the filter plate 15 to move to the right, so that the first slider 25 slides to the right inside the third slide groove 24, so that the two adjacent filter plates 15 are separated, and the filter cake between the two filter plates 15 falls. At the same time, the gradually straightened connecting chain 22 pulls the second paddle 14 moves to the right, and at the same time drives the second filter plate 15 to move to the right, and so on, until all the filter plates 15 are separated and all the filter cakes fall down. When the filter plate 15 is to be squeezed, before squeezing, the blocking column 19 is pulled to the left to make the blocking column 19 leave the fixed frame 13. At this time, the blocking column 19 no longer resists the blocking piece 12, and then the blocking piece 12 moves downward, so that the second slider 26 moves downward in the fourth slide groove 27. When the paddle 14 moves to the left, the blocking piece 12 does not resist the paddle 14. When the filter plates 15 are close to each other through the squeezing plate 6 and the hydraulic cylinder 8, the blocking column 19 is inserted into the fixed frame 13 again. The inclined surface at the right end of the blocking column 19 will prompt the blocking piece 12 to move upward, so that the second slider 26 slides upward in the fourth slide groove 27, so that the blocking piece 12 resists the paddle 14.
