[0002] A filter press is an important device widely used in industries such as chemical engineering, petroleum, ore dressing, pharmacy, and food to achieve the separation of solid and liquid phases. The main components of a filter press mainly include filter plates for realizing solid-liquid separation, a frame for supporting the filter plates, a pressing device, and a discharging device. During the working process of the filter press, first, the filter plates in the frame are pressed by the pressing device, and then the solid-liquid mixture is conveyed into the filter plates and pressurized to separate the solid and liquid phases. After the solid-liquid separation is completed, the tightly pressed filter plates are separated one by one by the discharging device, and the separated solid materials are discharged from between the filter plates, thereby realizing the separation of solid and liquid phases. Before processing, the existing filter presses need to wrap filter cloth around the filter plates. Currently, when wrapping the filter cloth, the filter cloth is hung on the positioning pins above the filter plates, and it is rather troublesome to level the filter cloth, which will wrinkle during work, resulting in incomplete filtering work, and the service life of the wrinkled part of the filter cloth is greatly reduced in the high-pressure environment inside.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 As shown, the present invention provides a filter cloth flatness adjustable filter plate press structure, including a filter press main beam unit 1. A thrust plate and a pressing plate 2 that approaches or moves away from the thrust plate are arranged in the filter press main beam unit 1. The filter plate press structure has a power unit for driving the pressing plate 2 to approach or move away from the thrust plate. The thrust plate is fixedly installed on the filter press main beam unit 1, and a plurality of filter plates 3 are arranged between the pressing plate 2 and the thrust plate. The filter plates 3 are slidably installed on the filter press main beam unit 1.

[0023] Filter cloths 4 are arranged on both sides of the filter plate 3. Of course, according to actual needs, there can be one filter cloth 4. In this case, one filter cloth 4 completely wraps the filter plate 3, and screws 5 are inserted at the four corners of the upper and lower ends of the filter plate 3 and the filter cloth 4. A tooth sleeve 6 is sleeved outside the middle part of the screw 5, and the tooth sleeve 6 is placed inside the four corners of the filter cloth 4. The inner side of the tooth sleeve 6 engages with a tooth part 7, and the tooth part 7 is placed inside the four corners of the filter cloth 4.

[0024] Please refer to Figure 1 And Figure 3 , in this embodiment, upper groove parts 31 are opened at both ends of the top and bottom of the filter plate 3, and a lower screw hole part 32 is opened at the bottom of the upper groove part 31. At the same time, a thread is provided on the inner wall of the lower screw hole part 32 for one week.

[0025] Further, there are a total of eight upper groove parts 31 and lower screw hole parts 32 at the top and bottom of the filter plate 3, and four in a group are respectively placed at the four corners of the top and bottom of the filter plate 3.

[0026] After the upper groove part 31 and the lower screw hole part 32 are provided on the filter plate 3, the screw 5 is inserted into the lower screw hole part 32, and the screw 5 is used to hang the filter cloth 4.

[0027] Further, the lower threaded end of the screw 5 is rotatably connected and inserted into the lower screw hole part 32, and the other ends of the screws 5 extend beyond the upper and lower ends of the filter plate 3.

[0028] Further, a tooth sleeve 6 is fixedly connected and sleeved outside the screw 5, and the tooth sleeve 6 is placed inside the upper groove part 31 below. At the same time, there is a distance between the outer wall of the tooth sleeve 6 and the inner wall of the upper groove part 31.

[0029] Among them, a gear sleeve 6 is sleeved above the screw 5. When the screw 5 is rotated, the gear sleeve 6 will also rotate accordingly, so as to adjust the filter cloth 4 by using the rotation of the gear sleeve 6.

[0030] Please refer to Figure 2 and Figure 4 , through the hanging hole parts 41 are provided at the four corners of the filter cloth 4, and the hanging hole parts 41 correspond to the upper groove parts 31.

[0031] Furthermore, a metal edging 8 is fixedly connected to the inner wall of the hanging hole part 41, and a tooth part 7 is fixedly connected to one side of the metal edging 8.

[0032] Furthermore, the other side of the metal edging 8 is tightly pressed against the gear sleeve 6.

[0033] A metal edging 8 is provided in the hanging hole part 41 on the filter cloth 4. When hanging the filter cloth 4, first, the metal edging 8 is sleeved outside the screw 5. At this time, the tooth part 7 inside the metal edging 8 will bite the gear sleeve 6. After rotating the screw 5, the gear sleeve 6 bites the tooth part 7 for adjustment.

[0034] Working principle:

[0035] Upper groove parts 31 are provided at the four corners of the upper and lower end faces of the filter plate 3, and lower screw holes 32 are provided at the bottoms of the upper groove parts 31. A screw 5 is inserted into the lower screw holes 32. In this way, the screw 5 can rotate in the lower screw holes 32 and the upper groove parts 31. A gear sleeve 6 is sleeved above the screw 5. At this time, the hanging hole parts 41 provided at the four corners of the filter cloth 4 are sleeved outside the screw 5 and the gear sleeve 6, and a metal edging 8 is provided in the hanging hole parts 41. At the same time, a tooth part 7 is provided on one side of the metal edging 8. In this way, the tooth part 7 will bite the gear sleeve 6. When the filter cloth 4 needs to be leveled, rotating the screw 5 drives the gear sleeve 6 to rotate. Since the rotation of the screw 5 will insert into or pull out of the filter plate 3, at this time, the upper groove parts 31 play a role in making the gear sleeve 6 also descend or ascend along with the screw 5, so that the gear sleeve 6 always bites the tooth part 7, and the four corners of the filter cloth 4 can be adjusted respectively to obtain a flat side.

[0036] In the description of this specification, the descriptions referring to the terms "one embodiment", "example", "specific example", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.
