Abstract
Description
Technical Field
[0001] This utility model relates to the field of diaphragm filter press technology, specifically to a linkage pressurization structure for a filter press. Background Technology
[0002] A diaphragm filter press is a filter press in which an elastic membrane is installed between the filter plates and the filter cloth. During operation, after feeding is completed, a high-pressure fluid or gas medium can be injected into the diaphragm plate. At this time, the entire diaphragm will bulge and compress the filter cake, thereby achieving further dewatering of the filter cake, which is commonly referred to as press filtration.
[0003] In existing filter presses, when the pressure plate moves along the crossbeam under pressure, it is connected to the crossbeam by rolling rollers. The rollers of the pressure plate are not properly positioned, making it prone to lateral displacement under the hydraulic cylinder's pressure. This compromises the sealing performance of the pressure plate on the filter plates. Furthermore, the existing pressure structure lacks a secondary positioning and fixing mechanism after the pressure plate is pressurized by the hydraulic cylinder. If the hydraulic cylinder malfunctions, the pressure plate cannot be effectively positioned, making it prone to loosening and compromising the clamping effect on the filter plates. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a linkage pressurizing structure for a filter press. By setting H-shaped limiting wheels, when the pressing plate moves along the crossbeam, the raised edges of the limiting wheels can be locked on both sides of the crossbeam, thereby making the pressing plate stably limited on the crossbeam and preventing the pressing plate from shifting to the left or right. This ensures the pressing and sealing performance of the pressing plate on the filter plate, and can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a linkage pressurizing structure for a filter press, comprising a pressing plate, a cross-shaped support rib fixedly connected to one side of the pressing plate, a limiting wheel installed at the center of the two symmetrical sides of the pressing plate, a limiting angle plate fixedly connected to the side of the pressing plate on one side of the limiting wheel, an electric push rod vertically arranged on the limiting angle plate, and an electric pin arranged on the lower side of the electric push rod.
[0006] Furthermore, a sealing plate is provided on the side of the clamping plate away from the supporting rib, and a connecting ear plate is fixedly connected to the circumferential side of the clamping plate.
[0007] Furthermore, a sealing ring is provided on the side of the sealing plate away from the pressing plate, and the sealing ring is embedded in the groove of the sealing plate.
[0008] Furthermore, a limiting sleeve is fixedly provided at the center of one side of the clamping plate where the supporting rib is located, and a hydraulic cylinder is installed inside the limiting sleeve.
[0009] Furthermore, a fixed seat is provided on the outer side of the end of the hydraulic cylinder away from the limiting sleeve, and the fixed seat is fixedly connected to the outer shell of the hydraulic cylinder.
[0010] Furthermore, the support rib is welded to the limiting sleeve, and the limiting wheel is connected to the pressing plate through a bearing seat.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The utility model uses H-shaped limiting wheels to ensure that when the pressing plate moves along the crossbeam, the protruding edge of the limiting wheel can be locked on both sides of the crossbeam, thereby stably limiting the pressing plate on the crossbeam and preventing the pressing plate from shifting to the left or right, thus ensuring the pressing and sealing performance of the pressing plate on the filter plate. 2. This utility model, through the setting of a limiting angle plate, an electric push rod, and an electric pin, allows the pressing plate to move into place under the push of the hydraulic cylinder. The electric push rod can then push the electric pin into the limiting hole of the crossbeam, effectively limiting the pressing plate. In the event of a malfunction of the hydraulic cylinder, the electric pin can be inserted into the limiting hole to limit the pressing plate, preventing it from becoming loose and affecting the pressure filtration effect.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-4 This embodiment provides a technical solution: a linkage pressurizing structure for a filter press, including a pressing plate 1, a cross-shaped support rib 2 fixedly connected to one side of the pressing plate 1, a limiting wheel 3 installed at the center of the two symmetrical sides of the pressing plate 1, a limiting angle plate 11 fixedly connected to the side of the pressing plate 1 on one side of the limiting wheel 3, an electric push rod 12 vertically arranged on the limiting angle plate 11, and an electric pin 10 arranged on the lower side of the electric push rod 12.
[0016] like Figure 1-4 As shown, during use, the hydraulic cylinder 5 pushes the pressing plate 1 and the sealing plate 7 to move, so that the sealing plate 7 presses the filter plate and the filter frame together. When the pressing plate 1 moves along the crossbeam, the limiting wheel 3 can be stuck on both sides of the crossbeam through the protruding edge, thereby limiting the lateral movement of the limiting wheel 3 and the pressing plate 1, preventing the pressing plate 1 from moving laterally during the movement, ensuring the pressing and sealing effect of the pressing plate 1 on the filter plate, and thus ensuring the filtration effect. After the pressing plate 1 moves into place, the electric push rod 12 can insert the electric pin 10 into the limiting pin hole of the crossbeam, so that the pressing plate 1 is stably fixed in a specific position on the crossbeam, preventing the pressing plate 1 from loosening due to damage to the hydraulic cylinder, and ensuring the pressing effect of the pressing plate 1 on the filter plate structure.
[0017] A sealing plate 7 is provided on the side of the clamping plate 1 away from the support rib 2, and a connecting ear plate 9 is fixedly connected to the circumferential side of the clamping plate 1.
[0018] A sealing ring 8 is provided on the side of the sealing plate 7 away from the pressing plate 1, and the sealing ring 8 is embedded in the groove of the sealing plate 7.
[0019] A limiting sleeve 4 is fixedly installed at the center of one side of the clamping plate 1 where the supporting rib 2 is provided, and a hydraulic cylinder 5 is installed inside the limiting sleeve 4.
[0020] A fixed seat 6 is provided on the outer side of the end of the hydraulic cylinder 5 away from the limit sleeve 4, and the fixed seat 6 is fixedly connected to the outer shell of the hydraulic cylinder 5.
[0021] The support rib 2 is welded to the limiting sleeve 4, and the limiting wheel 3 is connected to the pressure plate 1 through the bearing seat.
[0022] The working principle of the linkage pressurization structure for a filter press provided by this utility model is as follows: Figures 1-4As shown, during use, the hydraulic cylinder 5 pushes the pressing plate 1 and the sealing plate 7 to move, so that the sealing plate 7 presses the filter plate and the filter frame together. When the pressing plate 1 moves along the crossbeam, the limiting wheel 3 can be stuck on both sides of the crossbeam through the protruding edge, thereby limiting the lateral movement of the limiting wheel 3 and the pressing plate 1, preventing the pressing plate 1 from moving laterally during the movement, ensuring the pressing and sealing effect of the pressing plate 1 on the filter plate, and thus ensuring the filtration effect. After the pressing plate 1 moves into place, the electric push rod 12 can insert the electric pin 10 into the limiting pin hole of the crossbeam, so that the pressing plate 1 is stably fixed in a specific position on the crossbeam, preventing the pressing plate 1 from loosening due to damage to the hydraulic cylinder, and ensuring the pressing effect of the pressing plate 1 on the filter plate structure.
[0023] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
