Filter press mechanism and filter press

Abstract

This utility model relates to a filter press mechanism and a filter press, including a support arm and filter plates. A connecting seat is fixed to one side of the filter plate, and a guide wheel is movably connected to one end of the connecting seat. A guide groove is formed on the surface of the support arm, and the guide wheel is embedded in the guide groove and can slide along its length. A support frame is fixed to the surface of the support arm, and a limiting member is provided on the surface of the support frame. The limiting member fixes the position of the guide wheel relative to the guide groove. Through the design of the support arm and the limiting member, during the process of pushing multiple filter plates against the surface of the support arm to make them fit together, the guide wheel can roll within the corresponding guide groove. This facilitates the sliding of the filter plates. Simultaneously, because the center of gravity of the filter plates is designed to face downwards, tilting will not occur, maintaining the fit during subsequent pressing.

Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to the filter pressing mechanism and filter press. Background Technology

[0002] The filter press consists of three parts: the frame, which is the basic component of the filter press; the thrust plates and pressing heads at both ends; and the main beams on both sides connecting the two ends. The main beams support the filter plates, filter frames, and pressing plates. 1. Thrust Plate: It connects to the support, allowing one end of the filter press to rest on the foundation. In a chamber filter press, the thrust plate has a feed hole in the middle and four holes at the four corners. The holes at the top two corners are for the washing liquid or pressing gas inlet, and the holes at the bottom two corners are for the filtrate outlet (or filtrate outlet in a concealed flow structure). 2. Pressing Plate: Used to press the filter plates and filter frames together. Rollers on both sides support the pressing plate as it rolls along the tracks on the main beams. 3. Main Beams: These are load-bearing components. Depending on the corrosion requirements of the operating environment, they can be coated with rigid PVC, polypropylene, stainless steel, or new anti-corrosion coatings.

[0003] Currently, when using a filter press, filter plates need to be assembled sequentially and cooperate with each other. Finally, they are squeezed together by a hydraulic structure to form a cavity for filtration. However, in actual application, it has been found that there are a lot of particles on the filter plates after filtration. Therefore, the conventional method is to remove them for cleaning. However, because the particles are easy to fall off during the removal process, they cause dirt to accumulate in the surrounding area. Since the filter plates are vertical, it is not possible to clean them effectively without removing them. Therefore, a filter pressing mechanism and a filter press are proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In order to solve the above-mentioned problems of the prior art, the present invention provides a filter press mechanism and a filter press, which solves the problem that the filter plates are not easy to clean after filtration.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solution adopted by this utility model is as follows:

[0008] The filter press mechanism of the filter press includes a support arm and a filter plate. A connecting seat is fixed on one side of the filter plate, and a guide wheel is movably connected to one end of the connecting seat. A guide groove is opened on the surface of the support arm, and the guide wheel is embedded in the guide groove and can slide along its length.

[0009] A support frame is fixed to the surface of the support arm, and a limiting member is provided on the surface of the support frame. The limiting member can fix the position of the guide wheel relative to the guide groove.

[0010] The support arm is two in number, and the two support arms are distributed in parallel on both sides of the filter press plate.

[0011] The filter plate is connected to a filter tube on the other side, and a collection box is provided at the bottom of multiple filter tubes.

[0012] The limiting component includes a sliding groove formed on the surface of the support frame and a slider slidably disposed in the sliding groove;

[0013] The top of the slider is provided with a positioning pin, and the surface of the guide wheel is provided with a positioning groove that matches the positioning pin.

[0014] The limiting component also includes an abutment bolt threaded through the surface of the slider. Rotating the abutment bolt allows one end of it to abut against the surface of the support frame for positioning.

[0015] A filter press includes a filter pressing mechanism and a filter press body. The support arm and the collection box are both fixed to the surface of the filter press body. A hydraulic structure is installed on one side of the filter press body and an input structure is installed on the other side.

[0016] A collection tray is fixed at the bottom of the filter press body, corresponding to the position of the filter plate above.

[0017] The hydraulic structure includes a first side plate fixed to one side of the filter press body and a hydraulic telescopic rod fixed to the outside of the first side plate;

[0018] The output end of the hydraulic telescopic rod is fixed with a pressure plate for contacting the corresponding filter press plate.

[0019] The input structure includes a second side plate fixed to the other side of the press body. An input end is fixed on the surface of the second side plate. The press liquid can be input into the cavity formed between multiple filter plates by the action of the input end.

[0020] The top of the filter press body is fixed with a top frame.

[0021] Three beneficial effects

[0022] The beneficial effects of this utility model are: through the design of the support arm and the limiting part, when multiple filter plates are pushed to move on the surface of the support arm so that they fit together, the guide wheel can roll in the corresponding guide groove, which is conducive to the sliding of the filter plates. At the same time, since the center of gravity of the filter plates is designed to face downward, it will not tilt, thus maintaining the fit in the subsequent extrusion process.

[0023] By designing the limiting components, after the hydraulic structure contacts the squeezing state after filtration, the filter plates are moved to leave gaps between them. At the same time, the guide wheels can be used to tilt the filter plates at an angle, which facilitates the discharge of particles after pressurization. The positioning pins can also be inserted into the corresponding positioning grooves, which can ensure the positioning of the filter plates when tilting them, preventing them from deviating and making them easier to clean. The cleaned dirt can be collected uniformly in the collection tray below. Attached Figure Description

[0036] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Please refer to Figures 1 to 5As shown, the filter press mechanism of the filter press of this utility model includes a support arm 2 and a filter plate 1. Both sides of the filter plate 1 are fixed with connecting seats 11. A guide wheel 12 is movably connected to one end of the connecting seat 11. A guide groove 21 is opened on the surface of the support arm 2. The guide wheel 12 is embedded in the guide groove 21 and can slide along its length direction. The design of the guide wheel 12, which can roll freely, facilitates the movement of the filter plates 11 when they are close to each other, and also facilitates the separation and removal of multiple filter plates 1 after filtration.

[0038] A support frame 4 is fixed to the surface of the support arm 2, and a limiting member 41 is provided on the surface of the support frame 4. The limiting member 41 can fix the position of the guide wheel 12 relative to the guide groove 21. In actual implementation, after the filter press has finished filtration, the multiple filter plates 1 are separated, leaving gaps between them. Through these gaps, the filter plates 1 can swing at a certain angle, which can promote the falling off of the attached materials. At the same time, the limiting member 41 can also limit the guide wheel 12. This ensures that the position of the filter plates 1 will not shift during the swinging process, thus achieving better fixed-point cleaning.

[0039] Optionally, there are two support arms 2, which are distributed parallel to each other on both sides of the filter press plate 1. In actual implementation, the design of two support arms 2 allows the guide wheels 12 on both sides of the filter press plate 1 to be placed on the corresponding support arms 2, thus ensuring the stability of the filter press plate 1 after it is placed and preventing tilting.

[0040] Optionally, a filter pipe 13 is connected to the other side of the filter press plate 1, and a collection box 3 is provided at the bottom of multiple filter pipes 13. In actual implementation, after multiple filter press plates 1 are pressed together for filtration, the filtered liquid will be discharged to the outside through the filter pipes 13 on the sealed cavity formed between the multiple filter press plates 1, and the liquid discharged from the filter pipes 13 will drip into the collection box 3 for collection, achieving unified treatment.

[0041] Optionally, the limiting member 41 includes a sliding groove 42 formed on the surface of the support frame 4 and a slider 43 slidably disposed in the sliding groove 42;

[0042] The slider 43 has a positioning pin 44 inserted at its top, and the guide wheel 12 has a positioning groove 45 that matches the positioning pin 44. In actual implementation, when cleaning the filter press plate 1 requires fixing it in one spot, the slider 43 is moved to a suitable position so that one end of the positioning pin 44 is inserted into the positioning groove 45 on the corresponding guide wheel 12, thus fixing the position of the guide wheel 12 and ensuring that the filter press plate 1 can be kept in one spot for cleaning during the swinging process.

[0043] Optionally, the limiting member 41 further includes an abutting bolt 46 threaded through the surface of the slider 43. Rotating the abutting bolt 46 allows one end to abut against the surface of the support frame 4 for positioning. In actual implementation, rotating the abutting bolt 46 so that one end abuts against the surface of the support frame 4 can fix the slider 43, further improving the positioning effect of the positioning pin 44.

[0044] A filter press includes a filter pressing mechanism and a filter press body 5. The support arm 2 and the collection box 3 are both fixed to the surface of the filter press body 5. A hydraulic structure 6 is installed on one side of the filter press body 5 and an input structure 7 is installed on the other side.

[0045] Optionally, a collection tray 8 is fixed at the bottom of the filter press body 5, corresponding to the position of the filter press plate 1 above. In actual implementation, the design of the collection tray 8 allows for the collection of any adhering materials that fall during the aforementioned swinging and cleaning process of the filter press plate 1, thus preventing dirt from accumulating around the filter press.

[0046] Optionally, the hydraulic structure 6 includes a first side plate 61 fixed to one side of the filter press body 5 and a hydraulic telescopic rod 62 fixed to the outside of the first side plate 61;

[0047] The output end of the hydraulic telescopic rod 62 is fixed with a pressing plate 63 for contacting the corresponding filter press plate 1. In actual implementation, during filtration, multiple filter press plates 1 are placed on the support arm 2 and arranged at equal intervals. Then, the hydraulic telescopic rod 62 is activated so that its output end abuts against the pressing plate 63, causing the pressing plate 63 to slide towards the filter press plate 1 and eventually abut against the surface of the multiple filter press plates 1, so that the multiple filter press plates 1 are completely fitted together. In this way, the multiple filter press plates 1 form a chamber for filtration.

[0048] The input structure 7 includes a second side plate 71 fixed to the other side of the press body 5. An input end 72 is fixed on the surface of the second side plate 71. The input end 72 allows the press liquid to be input into the cavity formed between multiple filter plates 1. The liquid to be pressed and filtered is input into the cavity formed between multiple filter plates 1 through the input end 72. Filtration is achieved through the membrane of the filter plate 1 itself. The filtered liquid flows out to the outside through the filter pipe 13, while the solids adhere to the inside and are subsequently cleaned.

[0049] The top of the filter press body 5 is fixed with a top frame 9.
