Description

Technical Field

[0001] This utility model relates to the field of hydraulic disc filter technology, and specifically to a hydraulic disc filter. Background Technology

[0002] A hydraulic disc filter is a device that relies on liquid pressure to achieve automatic cleaning and high-efficiency filtration. During operation, the liquid to be filtered enters the filter under pressure, flowing from the outside to the inside of the disc assembly. The grooves and raised structures on the disc surface interweave to form numerous tiny filtration channels. Impurities in the liquid are trapped on the disc surface and within the filtration channels, and the filtered clean liquid flows out from the filter outlet, completing the filtration process.

[0003] Existing hydraulic disc filters typically consist of a chassis, filter discs, and a mounting cover. The filter discs are fixed inside the mounting cover by a frame, and the mounting cover is installed on the chassis by a threaded connection. However, during the use of hydraulic disc filters, the mounting cover is frequently subjected to the impact of water flow, which can easily cause the threaded connection between the mounting cover and the chassis to loosen, thus affecting the installation stability of the mounting cover. Utility Model Content

[0004] This invention proposes a hydraulic disc filter to solve the problem of low installation stability between the chassis and the mounting cover installed by threaded connection in the prior art.

[0005] The technical solution of this utility model is as follows: A hydraulic disc filter includes a chassis and a mounting cover. The mounting cover is disposed on one side of the chassis and also includes a mounting disc, filter elements, and a cylindrical frame. The mounting disc is fixedly disposed on the chassis, and the cylindrical frame is fixedly disposed on the mounting disc. Multiple filter elements are fitted on the cylindrical frame. A mounting ring is fixedly disposed at the bottom end of the side wall of the mounting cover. The mounting ring is fitted on the mounting disc and slidably connected to the side wall of the mounting disc. The chassis has an inlet and an outlet. The inlet communicates with the mounting cover, and the outlet communicates with the cylindrical frame. A positioning mechanism is provided between the mounting ring and the mounting disc for positioning the mounting ring and the mounting disc.

[0006] Preferably, a sealing ring is fixedly provided on the bottom side wall of the mounting cover, and the sealing ring is in contact with the mounting plate.

[0007] Furthermore, a limiting ring is fitted on the cylinder frame, a limiting plate is fixedly provided on the side wall of the limiting ring, and a support spring is fitted on the limiting ring. The two ends of the support spring are in contact with the mounting cover and the limiting plate, respectively.

[0008] Furthermore, the positioning mechanism includes an annular groove, a positioning groove, a positioning block, and a positioning post. The annular groove is formed on the outer wall of the mounting plate, and multiple positioning grooves are formed on one side of the inner wall of the mounting ring located on the annular groove. A positioning block is slidably disposed in the positioning groove, and an adjustment groove is formed on the top side wall of the positioning groove. A positioning post is fixedly disposed on the top side wall of the positioning block, and the positioning post extends into the adjustment groove. An adjustment mechanism is provided in the mounting ring for adjusting the position of the positioning post.

[0009] Furthermore, the adjustment mechanism includes a first cavity, an adjustment column, and an adjustment frame. The first cavity is provided inside the mounting ring on one side of the adjustment groove. The first cavity is connected to the adjustment groove. An adjustment column is rotatably disposed inside the first cavity. The adjustment frame is fixedly disposed on the side wall of the adjustment column. The positioning column extends into the adjustment frame. A driving mechanism is provided on the mounting ring for driving multiple adjustment columns to rotate synchronously.

[0010] Based on the above scheme, the driving mechanism includes a first gear, a driving ring, and a first toothed ring. The mounting ring has a second cavity on one side of the first cavity. The first gear is rotatably arranged in the second cavity. The first gear is fixedly connected to the adjusting column. A torsion spring is fitted on the adjusting column. The two ends of the torsion spring are fixedly connected to the adjusting frame and the side wall of the first cavity, respectively. An annular driving groove is formed on the outer wall of the mounting ring. The driving groove communicates with the second cavity. The driving ring is rotatably arranged in the driving groove. The first toothed ring is fixedly arranged on the inner wall of the driving ring. The first toothed ring meshes with the first gear.

[0011] The working principle and beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, by setting up an adjustment mechanism, the positioning column and positioning block can be moved by the operation of the adjustment mechanism. Then, the positioning block can be positioned between the mounting ring and the mounting plate by cooperating with the positioning groove and the annular groove respectively, thereby facilitating the improvement of the installation stability between the mounting cover and the chassis.

[0013] 2.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-6As shown, this embodiment proposes a hydraulic disc filter, including a chassis 1 and a mounting cover 2. The mounting cover 2 is disposed on one side of the chassis 1, and also includes a mounting disc 3, filter elements 4, and a cylindrical frame 5. The mounting disc 3 is fixedly disposed on the chassis 1, and the cylindrical frame 5 is fixedly disposed on the mounting disc 3. Multiple filter elements 4 are fitted on the cylindrical frame 5. A mounting ring 6 is fixedly disposed at the bottom end of the side wall of the mounting cover 2. The mounting ring 6 is fitted onto the mounting disc 3 and slidably connected to the side wall of the mounting disc 3. The chassis 1 has an inlet 7 and an outlet 8. The inlet 7 communicates with the mounting cover 2, and the outlet 8 communicates with the cylindrical frame 5. A positioning mechanism is provided between the mounting ring 6 and the mounting disc 3 for positioning the mounting ring 6. Positioning is achieved between the mounting cover 2 and the mounting plate 3. A sealing ring is fixedly installed on the bottom side wall of the mounting cover 2, and the sealing ring contacts the mounting plate 3. A limiting ring is fitted on the cylinder frame 5, and a limiting plate 9 is fixedly installed on the side wall of the limiting ring. A support spring 10 is fitted on the limiting ring, and the two ends of the support spring 10 contact the mounting cover 2 and the limiting plate 9 respectively. Specifically, liquid can be introduced into the mounting cover 2 through the inlet 7. Then, the liquid passes through the gap between the filter plates 4 to filter the liquid. After that, the filtered liquid is discharged through the cylinder frame 5 and the outlet 8. At the same time, the support spring 10 presses the filter plates 4 to prevent the gap between the filter plates 4 from changing and affecting the filtration effect.

[0025] Reference Figures 2-4 The positioning mechanism includes an annular groove 11, a positioning groove 12, a positioning block 13, and a positioning post 14. The outer wall of the mounting plate 3 has an annular groove 11, and the inner wall of the mounting ring 6 has multiple positioning grooves 12 on one side of the annular groove 11. The positioning block 13 is slidably arranged in the positioning groove 12. The top side wall of the positioning groove 12 has an adjustment groove 15, and the top side wall of the positioning block 13 is fixedly arranged with a positioning post 14. The positioning post 14 extends into the adjustment groove 15. The mounting ring 6 is provided with an adjustment mechanism for adjusting the position of the positioning post 14. Specifically, after the mounting ring 6 is fitted onto the mounting plate 3, the positioning post 14 and the positioning block 13 can be moved by the operation of the adjustment mechanism, so that one end of the positioning block 13 extends into the annular groove 11. Then, the positioning of the mounting ring 6 and the mounting plate 3 is achieved by the cooperation of the positioning block 13 with the positioning groove 12 and the annular groove 11, which facilitates the improvement of the installation stability between the mounting cover 2 and the chassis 1.

[0026] Reference Figures 2-6The adjustment mechanism includes a first cavity 16, an adjustment column 17, and an adjustment frame 18. The first cavity 16 is located on one side of the adjustment groove 15 within the mounting ring 6, and is connected to the adjustment groove 15. An adjustment column 17 is rotatably mounted within the first cavity 16. An adjustment frame 18 is fixedly mounted on the side wall of the adjustment column 17. A positioning column 14 extends into the adjustment frame 18. A drive mechanism is provided on the mounting ring 6 to drive multiple adjustment columns 17 to rotate synchronously. The drive mechanism includes a first gear 19, a drive ring 20, and a first gear ring. A second cavity is located on one side of the first cavity 16 within the mounting ring 6. The first gear 19 is rotatably mounted within the second cavity and is fixedly connected to the adjustment column 17. An adjustment column 17 is fitted with... Torsion spring 21, with its two ends fixedly connected to the adjusting frame 18 and the side wall of the first cavity 16 respectively. The outer wall of the mounting ring 6 is provided with an annular drive groove, which communicates with the second cavity. A drive ring 20 is rotatably arranged in the drive groove. A first toothed ring is fixedly arranged on the inner wall of the drive ring 20. The first toothed ring meshes with the first gear 19. Specifically, the rotation of the drive ring 20 can drive the first toothed ring to rotate. At the same time, the meshing of the first toothed ring with the first gear 19 drives the first gear 19, the adjusting column 17, and the adjusting frame 18 to rotate. Simultaneously, the adjusting frame 18 can push the positioning column 14 to adjust the position of the positioning column 14 and the positioning block 13, thereby facilitating the installation and removal of the mounting cover 2.

[0027] In this embodiment, during use, the operator rotates the drive disc, and the rotation of the drive ring 20 drives the first gear ring to rotate. At the same time, the meshing of the first gear ring with the first gear 19 drives the first gear 19 and the adjusting column 17. Thus, the rotation of the adjusting column 17 drives the adjusting frame 18 to move around the adjusting column 17. Simultaneously, the limiting of the positioning column 14 by the adjusting frame 18 pushes the positioning column 14 and the positioning block 13 to move. The movement of the positioning block 13 allows one end of the positioning block 13 to retract into the positioning groove 12. Then, the operator puts the mounting ring 6 on the mounting plate 3 and releases the drive ring 20. At this time, under the action of the torsion spring 21, the adjusting column 17 can be reset. Thus, the cooperation between the adjusting frame 18 and the positioning column 14 drives one end of the positioning block 13 to extend into the annular groove 11. In this way, the positioning block 13 cooperates with the positioning groove 12 and the annular groove 11 respectively to achieve positioning between the mounting ring 6 and the mounting plate 3, thereby improving the installation stability between the mounting cover 2 and the chassis 1.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
