Description

Technical Field

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

[0002] During operation, the positioning wheel, as a key component of the filter plate handle assembly, plays a crucial role in ensuring stable handle positioning and smooth operation. However, in practical applications, due to mechanical movement or improper operation, the positioning wheel frequently collides with the filter plate. This frequent impact not only accelerates the wear of the positioning wheel but may also lead to loosening or deformation of its internal structure, resulting in a series of malfunctions such as inaccurate positioning, operational jamming, or even complete failure. These malfunctions not only affect the normal operating efficiency of the equipment but also increase maintenance costs and downtime, adversely impacting the production process.

[0003] However, traditional filter plate handle designs often employ a highly integrated structure. When disassembling the positioning wheel for maintenance, repair personnel must first remove the connected mounting plates, bearings, and shafts one by one before they can access and replace the damaged positioning wheel. This process is not only time-consuming and labor-intensive, increasing the difficulty of maintenance, but may also damage other intact components due to improper operation during disassembly, further increasing maintenance costs. Utility Model Content

[0004] To address the aforementioned shortcomings, this utility model proposes a filter plate handle for a filter press. When disassembling the positioning wheel, the plug is rotated to separate it from the first mounting groove. Then, the rotating shaft is pulled out backward to separate it from the positioning wheel, thus completing the disassembly process of the positioning wheel. This solves the problem that traditional filter plate handles require complete disassembly before the positioning wheel can be replaced, which involves complex steps.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A filter plate handle for a filter press includes a pull plate, a positioning wheel, a bearing, a rotating shaft, and a plug.

[0007] The bottom of the pull plate has a downward-facing receiving groove, which horizontally extends through the left and right sides of the pull plate, and the positioning wheel is disposed in the receiving groove;

[0008] The rear side of the receiving groove is provided with a first mounting groove extending to the outer side of the pull plate, and the front side of the receiving groove is provided with a second mounting groove perpendicular to the inner side of the pull plate. The front end of the rotating shaft passes through the first mounting groove and is connected to the positioning wheel, and is located in the second mounting groove. The rear end of the rotating shaft is located in the first mounting groove.

[0009] The positioning wheel is slidably sleeved on the outer circumference of the rotating shaft via the bearing;

[0010] The plug is located at the rear end of the rotating shaft and is threadedly connected to the first mounting groove.

[0011] The outer periphery of the rotating shaft is provided with a first fastener and a second fastener, and the positioning wheel is located between the first fastener and the second fastener.

[0012] The first fastener is movably sleeved on the rotating shaft, and the front and rear sides of the first fastener abut against the inner wall of the receiving groove and the front side of the positioning wheel, respectively.

[0013] The second fastener is disposed at the rear end of the rotating shaft, the outer wall of the second fastener abuts against the inner wall of the second mounting groove, and the side wall of the second fastener abuts against the rear side of the positioning wheel.

[0014] The bearing is a tapered roller bearing.

[0015] A butterfly spring is provided between the plug and the rotating shaft, and the front and rear sides of the butterfly spring abut against the rotating shaft and the plug, respectively.

[0016] The front end of the pull plate is provided with a mounting part at the top and bottom. The mounting part is threadedly connected to a mounting component. The end of the mounting component is threaded through the mounting part and extends into the filter plate.

[0017] The pull plate has a handle at its rear end. The top of the handle is inclined from front to back to the bottom, and the bottom of the handle is located above the plug.

[0018] The outer surface of the positioning wheel is provided with an inwardly recessed movable groove, which is located in the middle section of the positioning wheel, and the cross-section of the movable groove is semi-circular.

[0019] The technical solution of this utility model can include the following beneficial effects:

[0020] 1. When disassembling the positioning wheel, rotate the plug to separate it from the first mounting groove, then pull the shaft out backward to separate it from the positioning wheel. This completes the disassembly process of the positioning wheel, solving the problem that the traditional filter plate handle requires complete disassembly before the positioning wheel can be replaced, which is a complicated process.

[0021] 2. The first and second fasteners can restrict the axial movement of the positioning wheel on the rotating shaft, prevent the positioning wheel from colliding with the inner wall of the receiving groove during operation, and ensure that the filter plate can be pulled smoothly and accurately, thereby enhancing the stability of the entire filter plate handle.

[0030] The following is combined Figures 1 to 3 This invention describes a filter plate handle for a filter press according to an embodiment of the present invention.

[0031] A filter plate handle for a filter press includes a pull plate 1, a positioning wheel 2, a bearing 3, a rotating shaft 4, and a plug head 7;

[0032] The bottom of the pull plate 1 is provided with a downward-facing receiving groove 11, which horizontally extends through the left and right sides of the pull plate 1, and the positioning wheel 2 is disposed in the receiving groove 11.

[0033] The rear side of the receiving groove 11 is provided with a first mounting groove that extends to the outer side of the pull plate 1, and the front side of the receiving groove 11 is provided with a second mounting groove that is perpendicular to the inner side of the pull plate 1. The front end of the rotating shaft 4 passes through the first mounting groove and is connected to the positioning wheel 2, and is located in the second mounting groove. The rear end of the rotating shaft 4 is located in the first mounting groove.

[0034] The positioning wheel 2 is slidably sleeved on the outer periphery of the rotating shaft 4 via the bearing 3;

[0035] The plug 7 is located at the rear end of the rotating shaft 4 and is threadedly connected to the first mounting groove.

[0036] When disassembling the positioning wheel 2, rotate the plug 7 to separate the plug 7 from the first mounting groove, and then pull out the rotating shaft 4 to separate the rotating shaft 4 from the positioning wheel 2. This completes the disassembly process of the positioning wheel 2, solving the problem that the traditional filter plate handle requires complete disassembly before the positioning wheel 2 can be replaced, which is a complicated process.

[0037] When installing or replacing a new positioning wheel 2, insert the front end of the rotating shaft 4 into the first mounting groove, then sequentially mount the mounting bearing 3 and the positioning wheel 2 onto the receiving groove 11. Next, continue pushing the rotating shaft 4 forward so that the front end of the rotating shaft 4 is in the second mounting groove and the rear end of the rotating shaft 4 is in the first mounting groove. Then rotate the plug 7 so that the rotating shaft 4 is completely located on the inner wall of the pull plate 1, preventing the rotating shaft 4 from loosening or falling off during operation, and ensuring that the handle can work normally and safely.

[0038] The outer periphery of the rotating shaft 4 is provided with a first fastener 62 and a second fastener 63, and the positioning wheel 2 is located between the first fastener 62 and the second fastener 63.

[0039] The first fastener 62 and the second fastener 63 can restrict the axial movement of the positioning wheel 2 on the rotating shaft 4, prevent the positioning wheel 2 from colliding with the inner wall of the receiving groove 11 during operation, ensure that the filter plate can be pulled smoothly and accurately, thereby enhancing the stability of the entire filter plate handle.

[0040] The first fastener 62 is movably sleeved on the rotating shaft 4, and the front and rear sides of the first fastener 62 abut against the inner wall of the receiving groove 11 and the front side of the positioning wheel 2, respectively.

[0041] The second fastener 63 is arranged around the rear end of the rotating shaft 4. The outer wall of the second fastener 63 abuts against the inner wall of the second mounting groove, and the side wall of the second fastener 63 abuts against the rear side of the positioning wheel 2.

[0042] The first fastener 62 can prevent the positioning wheel 2 from moving axially during operation and colliding with the inner wall of the receiving groove 11, thus preventing damage and extending the service life of the positioning wheel 2.

[0043] The second fastener 63 is ring-shaped at the rear end of the rotating shaft 4, with its outer wall abutting against the inner wall of the second mounting groove and its side wall abutting against the rear side of the positioning wheel 2. This all-around clamping method not only enhances the stability of the positioning wheel 2 but also reduces the relative movement between the positioning wheel and the rotating shaft, extending its service life.

[0044] The structural strength of the entire filter plate handle is significantly improved through the dual clamping action of the first fastener 62 and the second fastener 63. This design allows the filter plate handle to withstand greater tensile force, improving the operating efficiency and safety of the filter press.

[0045] The bearing 3 is a tapered roller bearing.

[0046] Tapered roller bearings are a type of bearing capable of withstanding combined radial and axial loads. Their inner and outer ring raceways are tapered, giving them self-aligning properties, large contact angles, high load-carrying capacity, and good rigidity.

[0047] When the plug 7 presses inward against the rotating shaft 4, a certain preload is generated between the inner and outer rings of the tapered roller bearing. This preload not only enhances the load-bearing capacity of the bearing 3 but also provides a certain damping effect during operation. When a larger pulling force is required, the preload can be increased by increasing the pushing force of the plug 7, thereby increasing the damping and making the filter plate move more stably. Conversely, when a smaller pulling force or a faster moving speed is required, the preload can be appropriately reduced to decrease the damping, making the operation more flexible and controllable.

[0048] A butterfly spring 61 is provided between the plug 7 and the rotating shaft 4, and the front and rear sides of the butterfly spring 61 abut against the rotating shaft 4 and the plug 7 respectively.

[0049] When the shaft 4 is subjected to impact or vibration during operation, the disc spring 61 can quickly absorb and disperse this energy, reduce the amplitude and frequency of the shaft 4's sway, effectively reduce the impact force when the positioning wheel 2 and the receiving groove 11 collide, thereby protecting key components such as the shaft 4, bearing 3 and receiving groove 11 from damage and extending the service life of the entire handle.

[0050] Furthermore, the disc spring 61 provides a constant preload after installation, ensuring stable positioning of the rotating shaft 4 within the circular mounting groove 12. This preload helps reduce the shaking of the rotating shaft 4 during rotation, improving positioning accuracy and stability, and making the filter plate handle smoother and more reliable to operate.

[0051] When maintenance or replacement is required, the disc spring 61 can be easily removed simply by removing the plug 7, without the need for complex disassembly of the entire handle structure, thereby reducing maintenance and time costs.

[0052] The front end of the pull plate 1 is provided with a mounting part 13 at the top and bottom. The mounting part 13 is threadedly connected to a mounting member 5. The end of the mounting member is threaded through the mounting part 13 and extends into the filter plate.

[0053] By providing mounting parts 5 at both the top and bottom of the mounting section 13 and inserting them into the filter plate using a threaded connection, the connection strength between the filter plate handle and the filter plate is enhanced. Compared to the traditional single-point connection, the multi-point connection is more resistant to external forces and vibrations, ensuring the stability of the filter plate handle during long-term use.

[0054] Furthermore, the threaded connection is self-locking, effectively preventing the filter plate handle from detaching from the filter plate even under external impact or vibration. This design improves the safety and reliability of the filter press during operation.

[0055] The pull plate 1 has a handle 14 at its rear end. The top of the handle 14 is inclined from front to back to the bottom, and the bottom of the handle 14 is located above the plug head 7.

[0056] The inclined top of the handle 14 can disperse stress and reduce the occurrence of excessive stress at a single point on the pull plate 1 and the handle 14, thereby enhancing the overall structural stability of the filter plate handle in this solution.

[0057] The bottom of the handle 14 is located above the plug 7, cleverly avoiding the positions of the plug 7 and the shaft 4, reducing interference between the filter plate handle and other components, and ensuring that the plug 7 and the shaft 4 can move and operate freely.

[0058] The outer surface of the positioning wheel 2 is provided with an inwardly recessed movable groove 21, which is located in the middle section of the positioning wheel 2. The cross-section of the movable groove 21 is semi-circular.

[0059] The semi-circular cross-section design of the movable groove 21 allows the positioning wheel 2 to fit more closely to the guide rail or slide of the filter press frame during sliding, preventing the positioning wheel 2 from shifting position during movement.

[0060] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
