Description

Technical Field

[0001] This utility model relates to the field of filter presses, and in particular to a continuous plate pulling mechanism for a filter press. Background Technology

[0002] According to the patent document with publication number CN219662967U, the patent document describes a chain drive system that drives a plate-pulling trolley to move and pull filter plates. When the plate-pulling trolley's picking claw touches the filter plate handle, it stops moving forward, the hydraulic motor reverses, and the chain drive system drives the plate-pulling trolley to retract. During the retraction, the picking claw pushes the filter plate handle to retract the filter plate. When the filter plate touches the pressure plate, it stops retracting, and the pressure plate presses down on the rear end of the picking claw. The front end of the picking claw disengages from the filter plate handle that has just been pulled back, and the plate-pulling trolley continues to pull the plate. This action is repeated until all the filter plates are pulled.

[0003] The patent document states that after the chain drive system pulls the filter plates apart one by one, the filter cake cannot be completely removed from the filter plate due to its stickiness. Some of the filter cake remains stuck on the filter cloth and needs to be manually removed, which is troublesome and slow. Utility Model Content

[0004] The purpose of this invention is to provide a continuous plate pulling mechanism for a filter press in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A continuous plate pulling mechanism for a filter press includes filter plates, a pulling mechanism, and a cleaning mechanism, wherein the cleaning mechanism is located on one side of the pulling mechanism;

[0007] The pulling mechanism includes two sliding seats, which are symmetrically distributed on the front and rear sides of the filter plate. A support plate is fixed on the top of each sliding seat, and a hydraulic cylinder is fixed on the top of each support plate. A limit frame is fixed on the extension and retraction end of each hydraulic cylinder, and a spring is fixed on the side of each limit frame away from the filter plate.

[0008] The cleaning mechanism includes two rotating shafts, which are rotatably connected to the top of two sliding seats. A scraper is provided between the two rotating shafts, and slide rods are fixed at both ends of the scraper. A cam is fixed at the top of the rotating shaft located in front of the filter plate.

[0009] Preferred configuration: Both sliding seats are threaded with lead screws at their bottoms, and slide rails are provided on both the front and rear sides of the bottom of the filter plate. The two sliding seats are slidably connected to the top of the two slide rails respectively, and handles are fixed on both the front and rear sides of the filter plate.

[0010] Preferably, both limiting frames have limiting grooves at their top for fitting the filter plate.

[0011] Preferably, a motor is fixedly installed at the input end of both rotating shafts, the lowest end of the two rotating shafts is lower than the lowest end of the filter plate, and the distance between the lowest end of the two rotating shafts and the lowest end of the filter plate is greater than the height of the scraper.

[0012] Preferably, the two slide rods are slidably connected to the two rotating shafts respectively, and the outer side of each of the two rotating shafts is provided with a helical groove for cooperating with the slide rods.

[0013] Preferably, the scraper is located on one side of the filter plate, and the side of the scraper closest to the filter plate is triangular.

[0014] Preferably, limiting plates are provided on both sides of both ends of the scraper, and the four limiting plates are respectively fixed to the top of the corresponding sliding seat.

[0015] The beneficial effects compared with the existing technology are as follows: by pulling the two limiting frames in the mechanism upward, the handles on the front and rear sides of the filter plate enter the limiting grooves of the two limiting frames and are located between the two springs. The rotating shaft in the cleaning mechanism drives the cam to rotate, and the cam intermittently hits the front side of the filter plate, causing the large filter cake on the filter plate to vibrate and fall off. The two rotating shafts rotate synchronously, driving the scraper to slide upward, thereby scraping off the fine filter cake residue on one side of the filter plate, further enhancing the cleaning effect of the filter cake.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8 As shown, a continuous plate pulling mechanism for a filter press includes a filter plate 1, a pulling mechanism 2, and a cleaning mechanism 3, with the cleaning mechanism 3 located on one side of the pulling mechanism 2.

[0030] In this embodiment: the pulling mechanism 2 includes two sliding seats 201, which are symmetrically distributed on the front and rear sides of the filter plate 1. A support plate 202 is fixed on the top of each sliding seat 201, and a hydraulic cylinder 203 is fixed on the top of each support plate 202. A limit frame 204 is fixed on the telescopic end of each hydraulic cylinder 203. A spring 205 is fixed on the side of each limit frame 204 away from the filter plate 1. A limit groove for cooperating with the filter plate 1 is opened on the top of each limit frame 204. The two sliding seats 201 drive the two limit frames 204 to move to the sides of the filter plate 1 respectively. The two hydraulic cylinders 203 push the two limit frames 204 to move upward, so that the handles on the front and rear sides of the filter plate 1 enter the limit grooves of the two limit frames 204 respectively. The two springs 205 cause the filter plate 1 to reset after being knocked and shaken by the cam 306.

[0031] In this embodiment: the cleaning mechanism 3 includes two rotating shafts 301, which are rotatably connected to the tops of two sliding seats 201 respectively. A scraper 303 is provided between the two rotating shafts 301. The scraper 303 is located on one side of the filter plate 1, and the side of the scraper 303 closest to the filter plate 1 is triangular. Limiting plates 305 are provided on both sides of both ends of the scraper 303. The four limiting plates 305 are fixed to the top of the corresponding sliding seats 201 respectively. Slide rods 304 are fixed at both ends of the scraper 303. The two slide rods 304 are slidably connected to the two rotating shafts 301 respectively. The outer side of the two rotating shafts 301 is provided with a spiral groove for cooperating with the slide rods 304. A cam 306 is fixed on the top of the rotating shaft 301 located on the front side of the filter plate 1. The input ends of the two rotating shafts 301 are fixed with... A motor 302 is installed, and the lowest ends of the two rotating shafts 301 are lower than the lowest end of the filter plate 1. The distance between the lowest ends of the two rotating shafts 301 and the lowest end of the filter plate 1 is greater than the height of the scraper 303. The two rotating shafts 301 are driven to rotate synchronously by the two motors 302. In turn, the two rotating shafts 301 drive the two sliding rods 304 to move synchronously upward in the vertical direction, thereby driving the scraper 303 to slide upward and scrape off the filter cake remaining on one side of the filter plate 1. The scraper 303 is limited at both ends by four limiting plates 305, so that the scraper 303 moves in the vertical direction. The rotating shaft 301 located on the front side of the filter plate 1 drives the cam 306 to rotate. In turn, the cam 306 intermittently hits the front side of the filter plate 1 during the rotation, causing the filter plate 1 to sway between the two springs 205.

[0032] In this embodiment: both sliding seats 201 are threaded with lead screws at their bottoms, and slide rails are provided on both the front and rear sides of the bottom of the filter plate 1. The two sliding seats 201 are slidably connected to the top of the two slide rails respectively. Handles are fixed on both the front and rear sides of the filter plate 1. By rotating the two lead screws, the two sliding seats 201 are driven to slide on the two slide rails along both sides, thereby driving the pulling mechanism 2 and the cleaning mechanism 3 to move.

[0033] Working principle: The rotation of two lead screws drives two sliding seats 201 to slide from one side to the other on two slide rails until the two sliding seats 201 drive the two limiting frames 204 to move to both sides of the first filter plate 1 they encounter. The two hydraulic cylinders 203 push the two limiting frames 204 upward, so that the handles on the front and rear sides of the filter plate 1 enter the limiting grooves of the two limiting frames 204 respectively. The rotation of the two lead screws drives the two sliding seats 201 to slide from one side to the other on two slide rails. During the sliding process of the two sliding seats 201, the two... Motor 302 drives two rotating shafts 301 to rotate synchronously. The rotating shaft 301 located in front of the filter plate 1 drives the cam 306 to rotate. As a result, the cam 306 intermittently hits the front of the filter plate 1 during rotation, causing the filter plate 1 to sway between the two springs 205. Large pieces of filter cake on the filter plate 1 fall off. During this process, the two rotating shafts 301 respectively drive the two sliding rods 304 to slide in the spiral groove and move upward in the vertical direction synchronously, thereby driving the scraper 303 to slide upward from the bottom of the filter plate 1. The scraper 303 scrapes off the fine filter cake remaining on one side of the filter plate 1.

[0034] After the first filter plate 1 is cleaned, the two rotating shafts 301 rotate in opposite directions, causing the scraper 303 to slide down from the top of the filter plate 1 to the bottom of the filter plate 1. The two hydraulic cylinders 203 pull the two limiting frames 204 downward, so that the handles on the front and rear sides of the filter plate 1 are disengaged from the two limiting frames 204 respectively, and the cleaning of the next filter plate 1 continues, and so on.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
