Description
Technical Field
[0001] This utility model relates to a plate puller, specifically a plate puller for a filter press. Background Technology
[0002] In the unloading process of a semi-automatic filter press, an automatic plate pulling mechanism combined with manual plate removal is typically used. Existing filter press plate pullers mainly consist of a plate puller base, a plate pulling hook, a plate removal hook, and a round-headed pin. When the round-headed pin is inserted, the plate removal hook is in the lowered position; when the round-headed pin is pulled out, the plate removal hook rises, thus working with the plate pulling hook to pull the filter plate into place.
[0003] However, this technology has significant drawbacks in practical use. After prolonged use, the round-headed pin is prone to loosening. During the plate removal process, the collision between the plate removal hook and the filter plate can cause the round-headed pin to press against the tail of the plate puller, preventing the plate removal hook from being properly pressed down as it passes the filter plate, resulting in plate removal jamming. If the round-headed pin is reinserted, the plate removal hook will fall, leading to the removal of an empty filter plate. This not only inconveniences the plate removal process but also poses operational risks.
[0004] Meanwhile, when the plate-retrieving hook is pressed down by the filter plate, it may not spring back in time, causing it to fail to properly retrieve a plate even after passing through multiple filter plates. In this case, the operator needs to manually assist in lifting the plate-retrieving device. During the process of lifting and pressing down the plate-retrieving hook, there is a high risk of hand pinching, posing a safety hazard to the operator. These problems seriously affect the efficiency and safety of the filter press's unloading process. Utility Model Content
[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a filter press plate puller, which effectively solves the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a pull plate base, a pull plate hook, and a plate retrieval hook, wherein a handle one and an operating handle two are respectively fixedly provided on the side of the plate retrieval hook and the pull plate hook near the operating platform; The base of the puller is provided with an extension bolt, which is located in the vertical position of the operating handle when the plate-removing hook falls. A hook is rotatably connected to the extension bolt; The arc-shaped end of the hook can be operably hooked onto the operating handle of the plate-retrieving hook to lock the plate-retrieving hook in its lowered state.
[0007] Preferably, the bottom end of the hook has a ring structure, and anti-loosening nuts are welded to both sides of the contact surface between the operating handle and the arc-shaped hook.
[0008] Preferably, the first operating handle and the second operating handle are welded to the middle of the side of the plate-retrieving hook and the plate-pulling hook.
[0009] Preferably, the inner side of the arc-shaped hook portion of the hook is provided with a rubber pad to increase the frictional resistance with the operating handle.
[0010] Preferably, when the pick-up hook is horizontal, the rotation path of the hook intersects with the operating handle.
[0011] Preferably, the hook is attached to an operating handle, and the operating handle extends beyond the hook.
[0012] Beneficial effects: Improved operational safety. By replacing the direct manual pressing of the pick-up and pull-up hooks with operating handle one and operating handle two, the risk of pinching hands during manual operation is eliminated, and safe unloading is achieved. The hook's anti-loosening nut and rubber pad design ensure reliable locking of the plate removal hook, avoiding operational risks caused by mechanical failure.
[0013] Overcoming the shortcomings of traditional technologies: By replacing the easily loose round-headed pin with a hook, the problems of plate removal jamming and empty filter plates caused by the movement of the round-headed pin are completely solved. Once the round-headed top pin is fixed, it no longer participates in the control of the plate-removing hook status, avoiding the phenomenon of "plate-carrying" or "empty removal" and improving the stability of unloading.
[0014] Equipment efficiency and reliability optimization: It reduced the failure rate of the plate puller during unloading, shortened the unloading time, and improved work efficiency.
[0015] The anti-detachment and friction-enhancing design ensures the reliability of the hook switching state and reduces equipment maintenance costs. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.
[0018] Example 1, by Figure 1-4 The present invention provides a filter press plate puller, including a plate puller base 1, a plate puller hook 2 and a plate take-up hook 4. The plate take-up hook 4 and the plate puller hook 2 are respectively fixedly provided with an operating handle 5 and an operating handle 6 on the side near the operating platform. The base 1 of the puller is provided with an extension bolt 7, which is located at the vertical position of the operating handle 5 when the plate hook 4 falls. A hook 8 is rotatably connected to the extension bolt 7; The arc-shaped end of the hook 8 can be operably hooked onto the operating handle 5 of the board-retrieving hook to lock the board-retrieving hook 4 in its lowered state.
[0019] Setting of operating handle 1 5 and operating handle 2 6: The lifting hook 4 and the pulling hook 2 are respectively fixedly welded to the middle of the side of the operating platform. When unloading, the method of lifting the lifting hook 4 or pressing the pulling hook 2 by hand is replaced by lifting the lifting hook 4 or pressing the pulling hook 2 by raising the operating handle 1 5 or pressing the operating handle 2 6.
[0020] Extension bolt 7 and hook 8 structure: An extension bolt 7 is provided on the base 1 of the puller. The extension bolt 7 is located in the vertical position of the operating handle 5 when the plate-retrieving hook 4 is lowered. A hook 8 is rotatably connected to the extension bolt 7. The bottom end of the hook 8 is a ring structure, and its arc end can be operably hooked onto the operating handle 5 of the plate-retrieving hook to lock the lowered state of the plate-retrieving hook 4.
[0021] Anti-slip and friction-increasing design: The contact surface between the operating handle 5 and the arc-shaped hook of the hook 8 is welded with an anti-slip nut. At the same time, the inner side of the arc-shaped hook of the hook 8 is provided with a rubber pad to increase the frictional resistance with the operating handle 5 and ensure reliable locking.
[0022] Positional relationship: When the hook 8 is hooked on the operating handle 5, the operating handle 5 extends beyond the hook 8, and when the pick-up hook 4 is horizontal, the rotation path of the hook 8 intersects with the operating handle 5, ensuring that when the hook 8 is hooked on the operating handle 5, the operating handle 5 still has an operating area extending beyond the hook 8.
[0023] Working principle: When using this utility model, the existing operation method is as follows: After the filter press finishes filtering, the filter plate is loosened, the original round head pin has been pulled out and welded to the base 1, and the plate hook 4 is initially in a raised state (e.g., Figure 1 At this time, hook 8 is not hooked onto operating handle 5, and hook 4 can move freely.
[0024] Filter plate pulling process Plate-taking hook pressing down and plate pulling: The plate puller moves along the guide rail driven by the sprocket and chain. When the plate-taking hook 4 contacts the filter plate to be pulled, it is pressed down. After passing through the filter plate, it moves to the left side and cooperates with the plate-pulling hook 2 to pull the filter plate to the right.
[0025] Pulling plate hook action: The operator presses the operating handle 26 of the pulling plate hook 2 to move the pulling plate hook 2 through the already positioned filter plate to the next filter plate to be pulled, and repeats the pulling plate action.
[0026] The operation method of this utility model is as follows: the hook is locked and released in state 4. Locking in the lowered state: When it is necessary to keep the plate-retrieving hook 4 in the lowered state, rotate the hook 8 so that its arc-shaped end hooks onto the operating handle 5. At this time, the anti-disengagement nut prevents the hook from moving laterally, and the rubber pad increases friction, ensuring that the plate-retrieving hook 4 is firmly locked and preventing it from lifting due to collision (e.g., Figure 4 , Figure 5 ).
[0027] Release the tilted state: When the plate hook 4 needs to be tilted, rotate the hook 8 to disengage it from the operating handle 5, and the plate hook 4 will return to the free tilted state, making it easier to be pressed down when contacting the next filter plate.
[0028] Safe operation alternative mechanism In the traditional method, operators need to press the pick-up hook 4 or pull the hook 2 directly with their hands, which poses a risk of pinching hands. After the modification, the pick-up hook 4 is raised / lowered by lifting the operating handle 1 5, and the pull hook 2 is pulled by pressing the operating handle 2 6, which realizes non-contact operation and eliminates safety hazards.
[0029] Hooks replace round-headed pins: The original round-headed pin 3 was prone to loosening, causing the plate removal to get stuck or the filter plate to be removed empty. Now, by hooking the operating handle 5 with hook 8, the plate removal hook 4 is locked in place, which completely solves the mechanical failure caused by the movement of the round-headed pin.
[0030] Anti-detachment and friction-enhancing design: The anti-detachment nut and rubber gasket ensure that the hook 8 and the operating handle 5 are stably hooked, preventing the plate hook 4 from accidentally lifting or falling during the unloading process, and ensuring the reliability of the operation.
[0031] Beneficial effects: Improved operational safety. By replacing the direct hand-pressing of the plate hook 4 and the pull hook 2 with the operation handle 5 and operation handle 6, the risk of pinching hands during manual operation is eliminated, and safe unloading is achieved.
[0032] The anti-loosening nut and rubber pad design of hook 8 ensures that the state of the plate removal hook 4 is reliably locked, avoiding operational risks caused by mechanical failure.
[0033] Overcoming the shortcomings of traditional technologies: Replacing the easily loose round-headed pin 3 with hook 8 completely solves the problems of plate removal jamming and empty filter plate removal caused by the movement of the round-headed pin.
[0034] Once the round-headed top pin is fixed, it no longer participates in the control of the plate-removing hook status, avoiding the phenomenon of "plate-carrying" or "empty removal" and improving the stability of unloading.
[0035] Equipment efficiency and reliability optimization: It reduced the failure rate of the plate puller during unloading, shortened the unloading time, and improved work efficiency.
[0036] The anti-detachment and friction-enhancing design ensures the reliability of the four-state switching of the plate-removing hook and reduces equipment maintenance costs.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
