Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically to a filter press mechanism. Background Technology

[0002] Plate and frame filter presses were the first machines used in chemical dewatering. Although plate and frame filter presses are generally operated intermittently, require large investments in infrastructure and equipment, and have relatively low filtration capacity, they are still widely used in some small wastewater treatment plants due to their advantages such as high filtration driving force, high solids content in the filter cake, clear filtrate, high solids recovery rate, and low consumption of conditioning chemicals.

[0003] Current plate filters require separating several filter plates after the material is pressed and filtered. The mud cake between adjacent filter plates can fall downwards in large quantities due to its own gravity; however, a small amount of mud cake will still stick to the filter plates, requiring manual scraping of the mud cake on the filter plates repeatedly, which makes the workload of the workers relatively large.

[0004] Therefore, we propose a filter press mechanism to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a filter press mechanism for a filter press, comprising two parallel crossbeams, each crossbeam having a support leg fixed at both ends, and a parallel fixing plate fixed between the two crossbeams. A first drive source is mounted on the outer side of one of the fixing plates, and a pressure plate is mounted on one end of the first drive source through the fixing plate. A plurality of filter press plates are arranged between the pressure plate and the other fixing plate. The top of the crossbeam has a sliding groove along its length, and a plurality of oscillating moving components are installed inside the sliding groove. The top of the oscillating moving components passes through the sliding groove and is connected to a mounting seat fixed to the side of the filter press plate. A first mounting plate is mounted below the crossbeam and fixed between the two support legs. A plurality of second drive sources are mounted below the first mounting plate, and the tops of the plurality of second drive sources pass through the first mounting plate and are fixed to the same lifting plate. A plurality of oscillating protrusions that cooperate with the oscillating moving components are mounted on the lifting plate.

[0007] Furthermore: the oscillating moving component includes a moving part slidably installed in a sliding groove, a through hole is provided at the center of the moving part, and an oscillating element is slidably installed inside the through hole. The bottom of the oscillating element is provided with a slope surface that cooperates with the oscillating protrusion. The top of the oscillating element is fixed with a second mounting plate passing through the through hole and the sliding groove in sequence.

[0008] Furthermore, the top of the movable component is fixed with a support ring that corresponds to the through hole, and the top of the support ring passes through the sliding groove and abuts against the bottom of the second mounting plate.

[0009] Furthermore, each of the two sides of the movable component is symmetrically fixed with a rotating shaft, and a movable wheel is rotatably mounted on each rotating shaft, with the movable wheel slidably mounted on the side of the sliding groove.

[0010] Furthermore: a limiting groove is formed on the side of the oscillating element in the vertical direction, and a limiting block is slidably installed inside the limiting groove, and the limiting block is fixed to the inner wall of the through hole.

[0011] Furthermore: the mounting base has a mounting hole at the corner, and the second mounting plate has a threaded hole at the corner; the mounting hole and the threaded hole are connected by fixing bolts.

[0012] The beneficial effects of this utility model are: This invention, through the cooperation of a first mounting plate, a second drive source, and a lifting plate, extends the vibrating protrusion into the interior of the crossbeam. When the filter press plate moves via the mounting base, the cooperation between the vibrating protrusion and the vibrating filter press assembly causes the filter press plate to vibrate during movement. The mud cake adhering to the filter press plate can fall off due to the vibration, eliminating the need for manual cleaning and thus providing convenience for workers. Attached Figure Description

[0015] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] A filter press mechanism includes two parallel crossbeams 1, with support legs 2 fixed at both ends of the crossbeams 1. The support legs 2 provide support for the crossbeams 1. It should be noted that a reinforcing rod 13 is fixed between every two support legs 1. The reinforcing rod 13 strengthens the support legs 2 and prevents the crossbeams 1 from deforming during use, thereby improving the stability of the filter press.

[0017] Two parallel fixing plates 3 are installed between the two crossbeams 1. In detail, each fixing plate 3 has a mounting bracket 14 fixed on both sides, and the mounting bracket 14 is fixed to the end of the crossbeam 1. The mounting bracket 14 serves to reinforce the fixing plate 3. One of the fixed plates 3 has a first drive source 4 fixed on its outer side. The first drive source 4 is an electric push rod. One end of the first drive source 4 passes through the fixed plate 3 and is fixedly connected to the pressure plate 5. When the first drive source 4 is driven, it can drive the pressure plate 5 to move towards the middle of the crossbeam 1 and squeeze several filter plates 6. A plurality of filter plates 6 are arranged between another fixing plate 3 and a pressure plate 5 (the filter plate is a well-known prior art, and will not be described in detail herein in this application). When the pressure plate 5 moves toward the middle of the cross beam 1, it can extrude the plurality of filter plates 6, and solid-liquid separation of materials can be performed through the plurality of filter plates 6. It should be noted that: mounting seats 8 are respectively fixed on two sides of the filter plates 6, and an oscillating moving assembly 7 is mounted below each mounting seat 8; it should be noted that: a sliding groove 101 with a "convex"-shaped cross-section is provided along the length direction at the top of the cross beam 1, and the oscillating moving assembly 7 is slidably mounted inside the sliding groove 101; after the filter press completes solid-liquid separation of materials, adjacent filter plates 6 are opened, a large amount of extruded mud cakes can fall downward under the action of their own gravity, and a small amount of mud cakes adhered to the filter plates 6 can also fall downward along with the oscillating force, which reduces the cleaning work of staff, thereby providing convenience for staff.

[0018] A first mounting plate 9 is arranged below the cross beam 1, and a plurality of second driving sources 10 are mounted at equal intervals at the bottom of the first mounting plate 9, the second driving sources 10 are also electric telescopic rods, the driving ends of the plurality of second driving sources 10 pass through the first mounting plate 9 and are fixedly connected with the bottom of the same lifting plate 11. It should be noted that: an accommodation groove 102 is provided along the length direction at the bottom of the cross beam 1, when the plurality of second driving sources 10 drive the lifting plate 11 to rise, the lifting plate 11 can move into the accommodation groove 102, and a plurality of oscillating protrusions 12 are mounted at equal intervals at the top of the lifting plate 11. It should be noted that: a plurality of insertion holes 103 are provided at equal intervals at the top of the accommodation groove 102, and the top of the insertion holes 103 communicate with the inside of the sliding groove 101; the top of the oscillating protrusions 12 can extend into the sliding groove 101 through the insertion holes 103, so that when the filter plate 6 moves inside the sliding groove 101 through the oscillating moving assembly 7, the filter plate 6 can oscillate repeatedly, and the mud cakes adhered to the filter plate 6 can fall off.

[0019] In detail: the oscillating moving component 7 includes a moving part 701, which is slidably installed inside the sliding groove 101; a through hole 702 is provided at the center of the top of the moving part 701, and an oscillating element 703 is slidably installed inside the through hole 702; the bottom end of the oscillating element 703 passes through the through hole 702 and is provided with a slope surface adapted to the oscillating protrusion 12. When the moving part 701 moves the oscillating element 703, the oscillating protrusion 12 can repeatedly lift and drop the oscillating element 703, thereby achieving the oscillation effect; a second mounting plate 704 is fixed to the top of the moving part 701 through the through hole 702 and the sliding groove 101 in sequence. It should be noted that a support ring 705 is fixed to the top of the moving part 701. Furthermore, the top of the support ring 705 passes through the sliding groove 101 and abuts against the bottom of the second mounting plate 704. The support ring 705 serves to support the second mounting plate 704, preventing the second mounting plate 704 from contacting the crossbeam 1. When the second mounting plate 704 moves, it can reduce friction and reduce the workload of the workers. It should be noted that the side of the vibrating element 703 has a limit groove 708 in a vertical direction. The inner wall of the through hole 702 is fixed with a limit block 709, and the limit block 709 is slidably installed inside the limit groove 708. Through the cooperation of the limit groove 708 and the limit block 709, the vibrating element 703 is limited, preventing the vibrating element 703 from detaching from the inside of the through hole 702. The movable component 701 has symmetrically fixed rotating shafts 706 on both sides, and each rotating shaft 706 has a movable wheel 707 rotatably mounted on it. Furthermore, the movable wheel 707 is rotatably mounted on the side of the sliding groove 101. It should be noted that there is a small area between the top of the movable wheel 707 and the inner top wall of the sliding groove 101 to prevent the upper part of the movable wheel 707 from contacting the top of the sliding groove 101, which would affect the sliding of the movable wheel 707. Through the cooperation of the rotating shaft 706 and the movable wheel 707, when the filter plate 6 is moved, the friction can be further reduced, thereby providing convenience for the staff. It should be noted that threaded holes are provided at the corners of the second mounting plate 704 and mounting holes are provided at the corners of the mounting base 8. When the mounting base 8 and the second mounting plate 704 are aligned with each other, the corresponding mounting holes and threaded holes are connected by fixing bolts. If the filter press plate 6 is used for a long time, it can also be removed from the crossbeam 1 for cleaning or maintenance.

[0020] After the material has been filtered using a filter press (filter press filtration is a well-known existing technology, and will not be described in detail here), the filtered cake can be removed from between the adjacent filter plates 6. When removing the sludge cake between adjacent filter press plates 6, firstly, several second drive sources 10 are activated. The drive ends of these second drive sources 10 can move the same lifting plate 11, allowing the lifting plate 11 to rise into the receiving groove 102. This allows the vibrating protrusion 12 on the lifting plate 101 to extend through the insertion hole 103 into the sliding groove 101. At this time, one end of the first drive source 4 can retract and move the pressure plate 5, so that the filter press plates 6 are in a non-compressed state. Then, the filter press plates 6 can be slid towards the pressure plate 5. When the filter press plates 6 move the second mounting plate 704 via the mounting seats 8 on both sides, the second mounting plate 704 can drive the moving part 701 through the vibrating element 703. The moving part 701 moves through the rotating shafts 706 on both sides, driving the moving wheels 707 to move within the sliding groove 101. When the bottom of the vibrating part 703 moves to the vibrating protrusion 12, the vibrating protrusion 12 provides support for the vibrating part 703, allowing the vibrating part 703 to drive the second mounting plate 704 upward, which in turn drives the filter press plate 6 upward. When one side of the vibrating part 703 detaches from the vibrating protrusion 12, the filter press plate 6 falls downward due to its own weight, thus achieving a vibrating effect. The mud cake adhering to the filter press plate 6 can fall off without manual cleaning, reducing the workload of the workers and providing them with convenience.

[0021] If the filter press plate 6 is used for a long time, it can be disassembled from the two crossbeams 1 for maintenance or cleaning.

[0022] When disassembling the filter press plate 6: first loosen the fixing bolts so that they can be removed from the threaded holes and mounting holes in sequence, thereby allowing the filter press plate 6 to be removed from the two vibrating moving components 7 and then cleaned.
