Abstract
Description
Technical Field
[0001] This utility model relates to slurry pressure filtration, and more particularly to a pressure filtration anti-splash liquid collection mechanism. Background Technology
[0002] A filter press consists of multiple rows of vertically placed filter plates. After these multiple filter plates are pressed together, they are used to feed slurry and filtrate to achieve solid-liquid separation of the slurry.
[0003] In practice, due to filter plate damage, slag inclusions between filter plates, etc., slurry or filtrate can easily spray (fly) from both sides of the filter plates onto the workshop floor, affecting the production environment and increasing the labor intensity of employees. When slag is trapped between filter plates, some slurry overflows from the bottom of the filter plate; if this part of the slurry cannot be recovered, it will result in material loss. Utility Model Content
[0004] The present invention aims to solve at least one of the technical problems mentioned above, and provides a pressure filter anti-splash liquid collection mechanism to effectively prevent slurry from splashing from the sides and bottom of the filter plate onto the floor, and facilitate the recovery of slurry overflowing from the bottom of the filter plate.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A pressure filter anti-splash liquid collection mechanism includes a frame, cantilever flaps, and a collection tank. The frame has multiple filter plates arranged axially. Two cantilever flaps are positioned below the filter plates, receiving filtrate and slurry discharged from below the filter plates. The mounting ends of the two cantilever flaps are hinged to both sides of the frame. The suspended ends of the two cantilever flaps are flipped relative to their mounting ends to form an upright V-shape or an inverted figure-eight shape. Two collection tanks receive filtrate and / or slurry flowing from both ends of the upright V-shape. A baffle extends upward from one side wall of the collection tank away from the filter plates, blocking filtrate flying out from the side of the filter plates. The cantilever flaps and / or the collection tank receive filtrate flowing from the drain nozzles of the filter plates.
[0007] Compared with the prior art, the beneficial effects of this application include: effectively preventing filtrate and slurry from spraying from the sides and bottom of the filter press to the floor, maintaining a clean production environment, and reducing material loss and cleaning costs.
[0008] As an improvement to the above technical solution, it also includes an opening and closing cylinder body. The cantilever flap is provided with a swing arm for driving it to flip. The two ends of each opening and closing cylinder body are respectively hinged to the swing arms of the two cantilever flaps. The opening and closing cylinder body is provided with two limiting parts that are respectively stopped by the two sides of the frame, so that the opening and closing cylinder body moves laterally in the vertical direction when driving the two cantilever flaps to flip.
[0009] As an improvement to the above technical solution, the limiting part includes a limiting shaft connected to the opening and closing cylinder and a pulley rotatably connected to the limiting shaft, the pulley being stopped by the frame.
[0010] As an improvement to the above technical solution, the two ends of the mounting end of the cantilever flap are connected to bearing seats by rolling bearings. The bearing seats at both ends of the mounting end of the cantilever flap together limit the movement of the cantilever flap. The bearing seats are used to connect the frame with screws.
[0011] As an improvement to the above technical solution, it also includes a flow-guiding sheet. The cantilever flap and the liquid collection tank on the same side are stacked on the same flow-guiding sheet. The flow-guiding sheet is used to bend and deform as the cantilever flap rotates. The cantilever flap is used to receive the filtrate and slurry of the filter plate through the flow-guiding sheet, and also to guide the filtrate and slurry to the liquid collection tank through the flow-guiding sheet.
[0012] As an improvement to the above technical solution, a pressure frame is also included, which is used to press the drainage soft sheet in the liquid collection tank so that the drainage soft sheet adheres to the inner wall and inner bottom of the liquid collection tank.
[0013] As an improvement to the above technical solution, the pressure frame includes multiple pressure strips extending axially along the liquid collection tank. The pressure strips are used to press the drainage soft sheet. The pressure frame is provided with multiple reinforcing rings spaced apart axially. The reinforcing rings are attached to the drainage soft sheet and are used to obstruct the flow of sediment in the liquid collection tank.
[0014] As an improvement to the above technical solution, a filter screen is provided at the end of the pressure frame. The filter screen is used to cover the discharge port of the liquid collection tank and to allow the filtrate and slurry to pass through.
[0015] As an improvement to the above technical solution, end-sealing plates are provided at both ends of the liquid collection tank, and at least one end-sealing plate is provided with a discharge port.

[0028] 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.
[0029] Reference Figures 1 to 4This utility model provides a filter press anti-splash liquid collection mechanism, which is essentially part of a corresponding filter press. It includes a frame 100, cantilever flaps 300, and a collection tank 400. Multiple filter plates 200 are axially arranged on the frame 100. Two cantilever flaps 300 are positioned below the filter plates 200, and are used to collect the filtrate and slurry discharged below the filter plates 200. The mounting ends 310 of the two cantilever flaps 300 are respectively hinged to both sides of the frame 100, meaning the cantilever flaps 300 are installed using a hinged method. The suspended ends 320 of the two cantilever flaps 300 are used to flip relative to the mounting ends 310 to form an upright A-shape or an inverted shape. The figure-eight shaped structure has two collection tanks 400, which are used to receive the filtrate and / or slurry flowing down from both ends of the upright V-shaped structure, i.e., the filtrate flowing down / cascading from the mounting end 310 of the cantilever flap 300. The collection tank 400 extends upward from one side wall of the filter plate 200 to form a baffle 410, which is used to block the filtrate flying out from the side of the filter plate 200. The cantilever flap 300 plays the role of receiving and guiding the material. The inverted figure-eight shape is used to center the filter cake falling from the filter plate 200 to the central axis of the discharge belt, so as to prevent the filter cake from being lost along the side of the discharge belt. The cantilever flap 300 and / or collection tank 400 are used to receive the filtrate flowing out from the drain nozzle 210 of the filter plate 200.
[0030] Understandably, a filter press includes a discharge belt located below the multiple filter plates.
[0031] Reference Figures 1 to 4 The operation process of this utility model can be as follows:
[0032] When the filter plate 200 is pre-filled with slurry, the suspended ends 320 of the two cantilever flaps 300 are raised, so that the two cantilever flaps 300 form an upright V-shape, that is, the two suspended ends 320 form a V-shape. At this time, the suspended ends 320 of the cantilever flaps 300 are higher, while the installation end 310 is lower. At this time, the multiple filter plates 200 of the filter press are squeezed together. That is, because the multiple filter plates 200 are arranged in a row, the adjacent two filter plates 200 are pressed together back and forth during the squeezing.
[0033] When the slurry is fed, the two cantilever flaps 300 maintain a V-shape and the filter plate 200 is fed. If there is slag between the filter plates 200, the slurry will overflow between the filter plates 200. The slurry drips from the bottom of the filter plate 200 to the cantilever flap 300 and is guided to the collection tank 400 by the cantilever flap 300. The on-site workers open the pipes and valves between the collection tank 400 and the slurry tank. If the slurry is sprayed out from the left or right side of the filter plate 200, the splashed slurry can be blocked and collected by the baffle 410. The slurry flows into the inner chamber of the collection tank 400 through the baffle 410.
[0034] During filter pressing, the two cantilever flaps 300 remain upright in a V-shape, and the filter plate 200 continuously feeds slurry. The water in the slurry seeps out through the filter cloth of the filter plate 200, and the discharge nozzle 210 of the filter plate 200 flows the water (filtrate) to the cantilever flaps 300 and / or the collection tank 400. If filtrate is sprayed out from the left or right side of the filter plate 200, the splashed filtrate can be blocked and collected by the baffle 410, and the filtrate flows into the inner chamber of the collection tank 400 through the baffle 410.
[0035] During the cake discharge process, the suspended ends 320 of the two cantilever flaps 300 tilt downwards, causing the two cantilever flaps 300 to form an inverted figure-eight shape, that is, the two cantilever flaps 300 form a central funnel. At this time, the multiple filter plates 200 of the filter press are far apart, and the filter cake on the filter plate 200 is released. The filter cake gradually collapses due to its own weight and / or the back-blowing air sprayed by the filter plate.
[0036] Reference Figure 4 The drain nozzle 210 is located directly below the collection tank 400. The drain nozzle 210 of the filter plate 200 will allow the filtrate to flow into the collection tank 400.
[0037] Compared with the prior art, the beneficial effects of this application include: effectively preventing filtrate and slurry from spraying from the sides and bottom of the filter press to the floor, maintaining a clean production environment, and reducing material loss and cleaning costs.
[0038] In some configurations, the hinge shaft of each cantilever flap 300 is connected to the rotating shaft of the corresponding motor, and the motor directly drives the cantilever flap 300 to flip, i.e., pitch and swing.
[0039] In some configurations, each cantilever flap 300 is driven by a corresponding cylinder, one end of which is hinged to the frame 100, and the other end is hinged to the middle or suspended end 320 of the cantilever flap 300.
[0040] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments of this utility model, it also includes an opening and closing cylinder 500, and a cantilever flap 300 is provided with a swing arm 330 for driving it to flip. The two ends of each opening and closing cylinder 500 are respectively hinged to the swing arms 330 of the two cantilever flaps 300. (Refer to...) Figures 1 to 3This invention features two opening / closing cylinders 500, one at the front and one at the rear. The front cylinder 500 is hinged to the front ends of the two cantilever flaps 300, and the rear cylinder 500 is hinged to the rear ends of the two cantilever flaps 300. Each cylinder 500 has two limiting parts 510 that are stopped by the sides of the frame 100, allowing the cylinder 500 to move laterally in the vertical direction when driving the two cantilever flaps 300 to flip. In this invention, the cylinder 500 moves laterally in the vertical direction when driving the cantilever flaps 300 to flip. With only one cylinder 500, the synchronous flipping of the two cantilever flaps 300 can be achieved, saving power and providing a convenient and stable control process. In this embodiment, the opening and closing cylinder 500 is used as the opening and closing power component. The front and rear ends of the cantilever flap 300 are connected to the opening and closing power component. The setting of the opening and closing power component does not hinder the filter cake from falling. The frame 100 is cleverly used to limit the movement of the opening and closing cylinder 500. The opening and closing cylinder 500 is limited to a stable vertical lateral movement, so that the cantilever flap 300 can be stably flipped.
[0041] The opening and closing cylinder 500 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.
[0042] Reference Figures 2 to 4 In some embodiments of this utility model, the limiting part 510 includes a limiting rotating shaft 511 connected to the opening and closing cylinder 500, and a pulley 512 rotatably connected to the limiting rotating shaft 511. The pulley 512 is suitable to be stopped by the frame 100. When the opening and closing cylinder 500 drives the cantilever flap 300 to flip, the opening and closing cylinder 500 smoothly moves laterally in the vertical direction, that is, to ensure the stable flipping of the cantilever flap 300.
[0043] Reference Figure 1 , Figure 2 In some embodiments of this utility model, the two ends of the mounting end 310 of the cantilever flap 300 are connected to bearing seats 350 through rolling bearings 340. The bearing seats 350 at both ends of the mounting end 310 of the cantilever flap 300 together limit the movement of the cantilever flap 300, and the rotation of the cantilever flap 300 is relatively stable. The bearing seats 350 are used to connect the frame 100 with screws. By disassembling the bearing seats 350, the bearing seats 350, rolling bearings 340 and cantilever flap 300 can be completely removed from the filter press. Then, the bearing seats 350 and rolling bearings 340 are disassembled in sequence.
[0044] In practice, the cantilever flap 300 is required to rotate, while the collection tank 400 remains fixed. There is a substantial gap between the mounting end 310 of the cantilever flap 300 and the collection tank 400, or even a significant height difference / distance / gap between them. A small amount of filtrate may flow along the lower arc of the mounting end 310 of the cantilever flap 300 and deviate from the collection tank 400, especially common when the cantilever flap 300 is rapidly extending the flow of liquid. (Refer to...) Figures 2 to 4In some embodiments of this utility model, a flow guiding sheet 610 is also included. The cantilever flap 300 and the liquid collection tank 400 on the same side are stacked on the same flow guiding sheet 610. The flow guiding sheet 610 is used to bend and deform as the cantilever flap 300 rotates. The cantilever flap 300 is used to receive the filtrate and slurry of the filter plate 200 through the flow guiding sheet 610, and is also used to guide the filtrate and slurry to the liquid collection tank 400 through the flow guiding sheet 610.
[0045] Furthermore, the connection between the drainage film 610 and the cantilever flap 300 can be adhesive, snap-fit, snap-fit, screw, etc.
[0046] When the drainage sheet 610 bends and deforms as the cantilever flap 300 rotates, the drainage sheet 610 tends to shift / be pulled towards the suspended end 320 of the cantilever flap 300. To solve this technical problem, while ensuring that the liquid receiving and draining of the collection tank 400 are not affected, refer to... Figures 1 to 4 In some embodiments of this utility model, a pressure frame 620 is also included. The pressure frame 620 is used to press the drainage soft sheet 610 in the liquid collection tank 400 so that the drainage soft sheet 610 is attached to the inner wall and inner bottom of the liquid collection tank 400.
[0047] Reference Figure 2 , Figure 3 The pressure frame 620 includes multiple pressure strips 621 extending axially along the collection tank 400. The pressure strips 621 are used to press down the drainage sheet 610. Multiple reinforcing rings 622 are spaced apart axially along the pressure frame 620. Each reinforcing ring 622 is synchronously connected to the multiple pressure strips 621. The reinforcing rings 622 abut against the drainage sheet 610 and are used to impede the flow of sediment in the collection tank 400, while also reinforcing the rigidity of the pressure frame 620. When there is minimal leakage between the filter plates 200, the collection tank 400 mainly collects filtrate, and a small amount of sediment flows at the bottom of the tank. The reinforcing rings 622 impede the flow of this sediment, and very little of the possible leakage flows into the filtrate storage tank.
[0048] Reference Figures 1 to 4 The end of the pressure frame 620 is provided with a filter screen 623. The filter screen 623 is used to cover the discharge port 421 of the collection tank 400. The filter screen 623 is used to allow the filtrate and slurry to pass through, and to prevent screws, nuts and other debris that may fall into the collection tank 400 from being discharged into the filtrate storage tank / slurry tank.
[0049] In some configurations, the liquid collection tank 400 is grounded via its own support; in other configurations, the liquid collection tank 400 is connected to the frame 100.
[0050] Reference Figure 1In some embodiments of this utility model, end-sealing plates 420 are provided at both ends of the liquid collection tank 400, that is, to seal the ends of the liquid collection tank 400. At least one end-sealing plate 420 is provided with a discharge port 421. The two ends of the liquid collection tank 400 are connected to the frame 100 through the end-sealing plates 420. The end-sealing plates 420 are used both to shield the front and rear ends of the filter plate cluster from splashing water and to install and fix the liquid collection tank 400.
[0051] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
