Description

Technical Field

[0001] This utility model relates to the technical field of plate and frame filter press equipment, and in particular to a plate pulling trolley for a plate and frame filter press. Background Technology

[0002] In the operation of a plate and frame filter press, the plate-pulling trolley is one of the key components. Its main function is to open and close the filter plates to complete the solid-liquid separation process. Traditional plate-pulling trolleys have a relatively simple structure, typically only possessing basic movement and plate-pulling functions. The plate-pulling trolley directly contacts the sides of the filter plates through a corresponding prying mechanism, achieving separation by prying or pulling the filter plates.

[0003] When manual intervention of the toggle switch position is required, operators sometimes have to directly touch the switch or toggle switch itself located below the equipment with their feet, which poses a safety hazard and is inconvenient to operate. In addition, the toggle switch may become stuck due to the accumulation of dirt or wear during long-term use, resulting in poor toggle switch release effect, which can affect the reliability of the pull-out action, leading to equipment downtime for maintenance and reduced work efficiency.

[0004] To address the aforementioned problems, this utility model document proposes a plate-pulling trolley for a plate and frame filter press. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as inconvenience and safety hazards when manually intervening in the position of the deflector, difficulty in quickly and safely handling when the deflector is stuck, and easy to affect the reliability of the plate pulling and the working efficiency. Therefore, a plate pulling trolley for a plate and frame filter press is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A plate-pulling trolley for a plate and frame filter press includes:

[0008] The movable seat has a C-shaped cross-section and slides with an external sliding rail. A fixing plate is fixedly installed on the top of the movable seat by bolts, and a mounting base is fixedly installed on the top of the fixing plate.

[0009] A first dial plate and a second dial plate are rotatably mounted on the mounting base. One side of the first dial plate is provided with an inclined surface, and one side of the second dial plate is provided with an arc surface.

[0010] Two torsion springs are provided inside the first and second levers. One end of each torsion spring is connected to the corresponding first and second levers, and the other end is connected to the mounting base.

[0011] Two fixing rods are respectively fixedly installed on one side of the first and second dial plates;

[0012] The inclined surface of the first lever is used to contact and pull the filter plate, the arc surface of the second lever is used to avoid the filter plate, and the two fixed rods allow the operator to manually press the corresponding first lever and second lever to rotate them.

[0013] In one possible design, a traction frame is fixedly mounted on the bottom of the mobile seat, the traction frame being used to cooperate with an external traction chain to drive the mobile seat to move.

[0014] One possible design also includes:

[0015] Multiple mounting brackets are fixedly installed on the top inner wall of the mounting base;

[0016] A movable rod slides through multiple fixed frames, and both ends of the movable rod are fixedly installed with abutment frames, one end of which is provided with an inclined surface;

[0017] Two lifting rods slide through the top of the mounting base. The two lifting rods cooperate with the first and second levers respectively. Each lifting rod has a fixed abutment rod. The abutment rod located above cooperates with the corresponding first or second lever, and the abutment rod located below cooperates with the inclined surface of the corresponding abutment frame.

[0018] When one of the dial plates is stuck, pressing the other dial plate will lift the stuck dial plate up through the lifting rod and the moving rod.

[0019] In one possible design, the middle section of the moving rod is threaded and connected to two limiting nuts. The outer wall of the moving rod is fitted with two springs, which are located on both sides of the fixed frame. One end of each spring abuts against the adjacent fixed frame, and the other end abuts against the adjacent limiting nut, so as to center and reset the moving rod.

[0020] In one possible design, anti-collision plates are fixedly installed near both ends of the movable seat, and both anti-collision plates are L-shaped to protect the movable seat.

[0021] In one possible design, a limiting plane is provided at the ends of the first and second levers that are far apart from each other to limit the rotation direction of the first and second levers.

[0022] In one possible design, two mounting brackets are fixedly mounted on the top of the mounting base, and the first and second dial plates are rotatably mounted inside the respective mounting brackets.

[0023] In one possible design, the rotation center of the torsion spring is coaxial with the rotation centers of the corresponding first and second levers.

[0024] In this application, during use, the plate-pulling trolley is connected to an external traction chain via a traction frame and moves along a sliding track under the drive of the chain. When the trolley moves towards the filter plate stack, the first deflector plate will first contact the side of the filter plate to be pulled apart. After the first deflector plate contacts the filter plate, the side of the filter plate acts on the inclined surface of the first deflector plate, which can push the first deflector plate to rotate against the elastic force of its internal torsion spring. After the first deflector plate moves to the other side of the filter plate, it will immediately return to its original position under the action of the torsion spring. Then, one end of the first deflector plate will abut against one side of the filter plate, and then the trolley continues to move, and the filter plate can be pulled by the first deflector plate.

[0025] After the filter plate is moved into place, the second push plate can make way for the already moved filter plate on the other side. Then the trolley can be pulled out from under the filter plate for the next push-pull operation.

[0026] When the first and second dial plates need to be rotated, if one side lacks a corresponding abutment, the user can press and rotate the corresponding dial plate by pressing the fixing rod. The fixing rod is set on one side of the two dial plates, which can ensure a high level of safety when pressing and rotating the corresponding dial plates.

[0027] After prolonged use, the first and second levers may become jammed during rotation. If either the first or second lever becomes jammed after rotation, the user can press the corresponding lever on the other side. This will cause the corresponding lifting rod to move downwards. As the lifting rod moves downwards, its bottom abutment rod contacts and pushes the inclined surface of the abutment frame at one end of the moving rod, allowing the moving rod to slide to the other side. This, in turn, allows the abutment frame at the other end to lift the other lifting rod, thus lifting the jammed lever under the action of the corresponding abutment rod.

[0028] When both the first and second levers are in the upright position, the two springs drive the moving rod to remain in the middle position, ensuring stable transmission. The fixed lever allows for manual operation or adjustment by pressing the levers when necessary. The anti-collision plates at both ends of the moving seat provide protection during movement, preventing damage from hard collisions with the track ends.

[0029] Beneficial effects: In this utility model, the plate-pulling trolley of a plate and frame filter press provides the operator with a clear and remote force application point away from moving parts by setting a fixing rod on the side of the plate. When manual rotation of the plate is required, the operator can directly press the fixing rod to complete the operation, effectively avoiding the need for the feet to directly contact the narrow or potentially dangerous area under the equipment, and significantly reducing the operational risk.

[0030] In this invention, the plate-pulling trolley of a plate and frame filter press features a unique plate reset and interlocking mechanism (composed of a lifting rod, a moving rod, a contact frame, and springs) that provides auxiliary reset when a single plate becomes stuck. When one plate becomes stuck and cannot reset itself, the operator can press the other working plate (using its fixing rod) to drive the lifting rod downwards, which in turn pushes the moving rod to slide through the inclined surface of the contact frame. The sliding of the moving rod will lift the lifting rod connected to the stuck plate, forcibly resetting the stuck plate. This design allows for quick handling of common jamming problems without disassembling the equipment, reducing maintenance time and improving the overall operational reliability and continuous operation capability of the equipment.

[0031] In this utility model, the spring and limit nut structure on the moving rod of the plate-pulling trolley of the plate and frame filter press can ensure that the moving rod automatically maintains the centered position when it is not subjected to external force, providing a stable and reliable transmission basis for the interlocking lifting action;

[0032] In this utility model, the plate pulling trolley of the plate and frame filter press has L-shaped anti-collision plates installed at both ends of the moving seat. These plates can buffer the trolley when it reaches the limit position of the track, preventing rigid collision between the moving seat and the end of the track, and protecting the main structure of the trolley from damage.

[0033] In this invention, the pull plate trolley significantly improves operational safety. The fixed rod provides a force application point away from dangerous areas, avoiding direct contact between the feet and the working surface. The unique interlocking mechanism of the dial plate can force the stuck dial plate to be reset by pressing the normal dial plate to drive the relevant rods when one side is stuck, quickly handling the fault, reducing downtime for maintenance, and enhancing the reliability of the equipment.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0042] In one embodiment: Refer to Figure 1-6 A pull-plate trolley includes components such as a movable seat 1, a fixed plate 2, a mounting seat 3, a first lever 4, a second lever 5, and a fixed rod 6, which work together to achieve the pull-plate function.

[0043] In this embodiment, the movable seat 1 is the basic support component of the entire pull-plate trolley. Its cross-section is C-shaped, which allows it to achieve a good sliding fit with the external sliding track. The sliding fit between the movable seat 1 and the external sliding track ensures that the movable seat 1 can move smoothly along the sliding track.

[0044] In this embodiment, a fixing plate 2 is bolted to the top of the movable base 1, serving as both a connector and a support. A mounting base 3 is fixedly mounted on the top of the fixing plate 2, providing a foundation platform for the installation of other components.

[0045] In this embodiment, two mounting brackets 7 are fixedly installed on the top of the mounting base 3. The first deflector plate 4 and the second deflector plate 5 are rotatably installed inside the corresponding mounting bracket 7. Specifically, a rotating shaft is fixedly provided inside the mounting bracket 7. The first deflector plate 4 and the second deflector plate 5 are respectively sleeved on the rotating shaft through corresponding bearings to achieve rotatable installation. One side of the first deflector plate 4 is provided with a slope, and one side of the second deflector plate 5 is provided with an arc surface. The design of the slope and the arc surface allows the first deflector plate 4 and the second deflector plate 5 to better avoid contact with corresponding objects.

[0046] In this embodiment, a limiting plane is provided at the ends of the first lever 4 and the second lever 5 that are far apart from each other. The setting of the limiting plane can restrict the rotation direction of the corresponding first lever 4 and the second lever 5, and prevent the first lever 4 and the second lever 5 from rotating excessively.

[0047] In this embodiment, both the first shift plate 4 and the second shift plate 5 are equipped with torsion springs 10 inside, and the rotation centers of the first shift plate 4 and the second shift plate 5 are on the same straight line as the corresponding torsion springs 10. One end of each torsion spring 10 is fixedly connected to the inner wall of the corresponding first shift plate 4 and second shift plate 5 through a spring seat 15, and the other end of each torsion spring 10 is fixedly connected to the top of the mounting base 3 through a spring seat 15. When the first shift plate 4 and the second shift plate 5 are rotated under the action of an external force, the torsion springs 10 will undergo elastic deformation. When the external force disappears, the torsion springs 10 can restore the first shift plate 4 and the second shift plate 5 to their initial positions.

[0048] In this embodiment, two fixing rods 6 are welded to one side of the first dial plate 4 and the second dial plate 5, respectively. The fixing rods 6 provide convenient operating positions for the operator, who can press the fixing rods 6 to rotate the first dial plate 4 and the second dial plate 5, ensuring good operational safety.

[0049] In this embodiment, multiple fixing brackets 11 are fixedly installed on the top inner wall of the mounting base 3, and a common moving rod 12 slides through the multiple fixing brackets 11. Abutment brackets 13 are fixedly installed at both ends of the moving rod 12, and one end of each abutment bracket 13 is provided with an inclined surface. Two lifting rods 16 slide through the top of the mounting base 3, and both lifting rods 16 are located between the first deflector plate 4 and the second deflector plate 5 and respectively cooperate with the first deflector plate 4 and the second deflector plate 5. Abutment rods 17 are fixedly installed near both ends of the two lifting rods 16. The two upper abutment rods 17 cooperate with the adjacent first deflector plate 4 and the second deflector plate 5 respectively, and the two lower abutment rods 17 are located inside the mounting base 3 and respectively cooperate with the inclined surface of the corresponding abutment bracket 13. When the moving rod 12 moves, it will drive the abutment frame 13 to move. The inclined surface of the abutment frame 13 contacts the lower abutment rod 17, causing the lifting rod 16 to rise or fall. The movement of the lifting rod 16 will then drive the upper abutment rod 17 to move, thereby affecting the first lever 4 and the second lever 5.

[0050] In this embodiment, the middle section of the moving rod 12 is threaded and fitted with two limiting nuts 14. Two springs 15 are fitted onto the outer wall of the moving rod 12. The two limiting nuts 14 and the two springs 15 are located on either side of the centrally located fixed frame 11. One end of each spring 15 abuts against one side of the adjacent fixed frame 11 via a spring 15 seat, and the other end of each spring 15 abuts against one side of the adjacent limiting nut 14 via a spring 15 seat. When the moving rod 12 is moved by an external force, the springs 15 are compressed or stretched. When the external force disappears, the elastic force of the springs 15 causes the moving rod 12 to return to its central position, achieving the centering and resetting of the moving rod 12.

[0051] This application can be used in the field of plate and frame filter press equipment technology, as well as in other fields applicable to this application.

[0052] In another embodiment: Reference Figure 2 , 3 A plate-pulling trolley for a plate and frame filter press, which is applied to the technical field of plate and frame filter press equipment;

[0053] In this embodiment, anti-collision plates 9 are fixedly installed near both ends of the movable base 1, and both anti-collision plates 9 are L-shaped. The anti-collision plates 9 are fixed to the movable base 1 with bolts, and their function is to protect the two ends of the movable base 1 and prevent the movable base 1 from colliding with other objects and being damaged during movement.

[0054] In this embodiment, a traction frame 8 is fixedly installed on the bottom inner wall of the movable seat 1. The traction frame 8 cooperates with the external traction chain. When the external traction chain moves, the traction frame 8 moves accordingly, thereby driving the movable seat 1 to move.

[0055] The working principle and usage process of this technical solution are as follows: During use, the trolley is connected to the external traction chain via the traction frame 8, and moves along the sliding track under the drive of the chain. When the trolley moves towards the filter plate stack, the first lever 4 will first contact the side of the filter plate to be pulled apart. After the first lever 4 contacts the filter plate, the side of the filter plate acts on the inclined surface of the first lever 4, which can push the first lever 4 to rotate against the elastic force of its internal torsion spring 10. After the first lever 4 moves to the other side of the filter plate, it will immediately return to its original position under the action of the torsion spring 10. Then, one end of the first lever 4 will abut against one side of the filter plate, and then the trolley continues to move, and the filter plate can be moved by pulling it through the first lever 4.

[0056] After the filter plate is moved into place, the second push plate 5 can make way under the action of the filter plate that has been moved on the other side. Then the trolley can be pulled out from under the filter plate for the next push-pull operation.

[0057] When the first dial 4 and the second dial 5 need to be rotated, if there is no corresponding abutment on one side, the user can press and rotate the corresponding dial by pressing the fixing rod 6. The fixing rod 6 is set on one side of the two dials, which can ensure a high level of safety when pressing and rotating the corresponding dial.

[0058] After prolonged use, the first dial 4 and the second dial 5 may become stuck during rotation. When one of the dials becomes stuck after rotation, the user can press the other dial accordingly. At this time, the lifting rod 16 that cooperates with it will move downward. When the lifting rod 16 moves downward, the abutment rod at its bottom contacts and pushes the inclined surface of the abutment frame 13 at one end of the moving rod 12, allowing the moving rod 12 to slide to the other side. This allows the abutment frame 13 at the other end to lift the other lifting rod 16, and then the corresponding abutment rod 17 can lift the stuck dial.

[0059] When both the first lever 4 and the second lever 5 are in the upright position, the two springs 15 drive the moving rod 12 to remain in the middle position, ensuring stable transmission of the moving rod 12. The fixed rod 6 facilitates manual pressing of the levers for operation or adjustment when necessary. The anti-collision plates 9 at both ends of the moving seat 1 provide protection during movement, preventing damage from hard collisions between the moving seat 1 and the end of the track.

[0060] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0061] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
