Description

Technical Field

[0001] This invention relates to the field of filter press flushing technology, specifically to a high-pressure online flushing device and control system for a filter press. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device. In the production of polyvinyl chloride (PVC), plate and frame filter presses are often used to dewater carbide slag. However, during the operation of the filter press, due to the high viscosity of carbide slag, some filter cake remains stubbornly adhered to the filter cloth after the filter cake is unloaded. Manual intervention is required to clean the filter cloth. At the same time, the filter pores can become clogged by fine particles during the filtration process, resulting in decreased filtration efficiency and increased moisture content in the filter cake. Therefore, it is necessary to remove the filter press regularly for manual cleaning, which is not only time-consuming and labor-intensive but also affects the continuity of production. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention separates the filter plates by using a trolley for unloading. Water is then pumped from the storage tank and transported through a telescopic pipe to the spray pipe. The water is then sprayed onto the surface of the filter cloth by a rinsing head, reducing the need for manual cleaning. Furthermore, as the trolley moves with the mobile vehicle, each filter plate can be rinsed individually after the trolley reaches it.

[0015] During the movement of the unloading trolley, the present invention will also drive the spray pipe to slowly deflect through the pulling component, so that the flushing head can flush the filter cloth from top to bottom, which can increase the flushing range of the filter cloth and thus improve the flushing effect of the filter cloth.

[0016] When the spray pipe rotates, the present invention also applies force to the reciprocating component and drives the moving plate to move up and down, thereby driving the striking rod to move together. This allows the striking rod to strike the top of a single filter plate, thereby improving the filter cake unloading effect and facilitating better subsequent rinsing. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-9 As shown, a high-pressure online flushing device for a filter press includes a filter press body 110, guide rails 120 mounted on both sides of the filter press body 110, and a discharge trolley 130 slidably connected to the guide rails 120. A flushing section 200 is fixed on the discharge trolley 130. The flushing section 200 includes a moving carriage 210 slidably connected to the guide rails 120. The discharge trolley 130 is located between the moving carriages 210. Fixing frames 220 are fixed on both sides of the outer end of the discharge trolley 130. A spray pipe 230 is rotatably connected to the top of the inner cavity of the fixing frame 220. Several flushing heads 240 are connected to the bottom of the filter press 230. A telescopic pipe 250 is rotatably connected to the rear end of the spray pipe 230. A water storage tank 260 and a water pump 270 are fixed at the rear of the filter press body 110. The suction end of the water pump 270 is connected to the top of the water storage tank 260, and the discharge end of the water pump 270 is connected to the telescopic pipe 250. A striking element 280 for striking and vibrating the filter plate is provided on the fixed frame 220. A pulling element 290 is provided in front of the fixed frame 220, which can pull and rotate the spray pipe 230 by moving the unloading trolley 130.

[0021] The striking component 280 includes a fixed plate 281 fixed to the left side of the fixed frame 220. Several striking rods 282 slide through the interior of the fixed plate 281. A movable plate 283 is fixed to the other end of each striking rod 282. A reciprocating assembly 284 is provided at the front of the fixed frame 220 to move the movable plate 283. When the spray pipe 230 rotates, the reciprocating assembly 284 moves the movable plate 283, which in turn moves the striking rods 282, thereby striking and vibrating the filter plate to facilitate... The subsequent rinsing reciprocating assembly 284 includes a movable disc 2841 fixedly connected to the front end of the spray pipe 230. A push plate 2842 is rotatably connected to the surface of the movable disc 2841, and the other end of the push plate 2842 is rotatably connected to the surface of the other end of the moving plate 283. When the spray pipe 230 rotates, it will drive the movable disc 2841 to rotate and drive the push plate 2842 to deflect. When deflected, the push plate 2842 will be pulled or pushed to facilitate the moving plate 283 to move up and down reciprocally.

[0022] The pulling component 290 includes a rack plate 291 slidably connected to the right side of the front end of the fixed frame 220. A gear 292 is fixedly connected to the surface of the front spray pipe 230. The right side of the gear 292 meshes with the left side of the rack plate 291. A pull rope 293 is fixed to the bottom of the folded end of the rack plate 291. The other end of the pull rope 293 is fixed to the surface of the front unloading trolley 130. When the unloading trolley 130 moves to the left, it pulls the pull rope 293, causing the rack plate 291 to move downward, thereby causing the gear 292 to rotate and the spray pipe 230 to rotate, facilitating subsequent rinsing. 90 also includes a support plate 294, which is fixed to the front end of the fixing frame 220. A movable rod 295 slides through the inside of the support plate 294. The other end of the movable rod 295 is fixed to the top of the folded end of the rack plate 291. A tension spring 296 is sleeved on the surface of the movable rod 295. The two ends of the tension spring 296 are fixed between the support plate 294 and one end of the rack plate 291. When the rack plate 291 is not under force, the tension force of the tension spring 296 will drive the rack plate 291 to move upward, thereby driving the spray pipe 230 to deflect to the starting position through the gear 292.

[0023] It also includes a shielding component 300, which includes a movable ring 320 rotatably connected to both sides of the spray pipe 230. A shielding plate 310 for shielding the flushing head 240 is fixed at the bottom of the spray pipe 230. A pull rod 330 is hinged to the top of the movable ring 320. Through the rotatable connection between the movable ring 320 and the surface of the spray pipe 230, the shielding plate 310 can be rotated so that when the flushing head 240 is not in use, the shielding plate 310 can shield and protect the tension member 340.

[0024] The shielding component 300 also includes a tensioning component 340, which includes a movable rod 341 that slides through the folded end of the telescopic tube 250. One end of the movable rod 341 is fixedly connected to a sealing disc 342, and a compression spring 344 is sleeved on the surface of the movable rod 341. The two ends of the compression spring 344 are fixed to one side of the sealing disc 342 and the inner wall of the telescopic tube 250. The other end of the movable rod 341 is fixed to a pull plate 343, and the other end of the pull plate 343 is hinged to the other end of the pull rod 330. When water enters the telescopic tube 250, it will push and impact the sealing disc 342, and drive the movable rod 341 to move together, thereby driving the pull plate 343 to move as well, and pulling the pull rod 330, causing the movable ring 320 to deflect at an angle, thereby canceling the shielding protection of the flushing head 240.

[0025] A sliding groove 500 is provided on the front of the inner side of the fixed frame 220. A sliding plate 400 is fixed on one side of the rack plate 291. The sliding plate 400 is slidably connected to the inside of the sliding groove 500. Through the sliding connection between the sliding plate 400 and the inside of the sliding groove 500, the rack plate 291 can be auxiliaryly supported and its stability can be maintained when it moves up and down.

[0026] A guide wheel 600 is rotatably connected to the surface of the fixed frame 220. The pull rope 293 is in contact with the inner side of the guide wheel 600. The guide wheel 600 can guide the pull rope 293, making it convenient to pull the rack plate 291.

[0027] A high-pressure online flushing control system for a filter press includes a main processor, a control module, and a transmission module. The output of the main processor is electrically connected to the input of the control module, and the output of the control module is electrically connected to the input of the transmission module. After the filter press body 110 performs filtration, the signal output of the main processor is transmitted through the control module, and the transmission module controls the unloading trolley 130 and the water pump 270 respectively, so that the unloading trolley 130 can pull and separate the filter plates, and the water pump 270 can extract water.

[0028] Working principle: After the filter press body 110 completes filtration, the unloading trolley 130 moves to the left. During this movement, it pushes the moving trolley 210 and the fixed frame 220 to move as well. When the unloading trolley 130 reaches the filter plate, it moves the filter plate back to its starting position, separating adjacent filter plates. While the unloading trolley 130 is moving, water is pumped in by the water pump 270, which applies force to the tensioning member 340 through the telescopic pipe 250, causing the baffle plate 310 to deflect at an angle. The water then enters the spray pipe. In section 230, the material is sprayed through the flushing head 240. When the unloading trolley 130 moves back, the tension of the tension spring 296 drives the rack plate 291 to move upward and rotates the gear 292. At the same time, the spray pipe 230 rotates, allowing the flushing head 240 to deflect and flush, thereby expanding the flushing range. When the spray pipe 230 rotates, the reciprocating assembly 284 moves the moving plate 283 up and down, thereby driving the striking rod 282 to strike the filter plate, thus improving the subsequent flushing effect.
