Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically a filter device. Background Technology

[0002] Bag filters are multi-purpose filtration devices characterized by their novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed-loop operation, and wide applicability. Bag filters are a new type of filtration system. Inside the bag filter, a metal mesh basket supports the filter bag. Liquid flows in through the inlet, is filtered by the filter bag, and flows out through the outlet, while impurities are trapped within the filter bag.

[0003] CN202411741815.5 discloses a bag-type quick-opening filter. A filter cartridge is installed in the mounting hole, and a filter bag is fitted onto the filter cartridge. A first sealing structure is provided between the limiting groove and the outer side of the sealing ring. A pressure ring is provided on the sealing ring, and a filter layer is provided between the pressure ring and the sealing ring. A guide rod is provided on the sealing ring, and a first guide hole is provided on the pressure ring for the guide rod to pass through. A spring is fitted onto the guide rod, with the top of the spring abutting against the bottom of the limiting rod and the bottom of the spring abutting against the pressure ring. Rotation limiting devices are provided on both sides of the mounting opening of the filter plate. These rotation limiting devices cooperate with the two ends of the limiting rod along its length to restrict the rotation and lifting of the limiting rod. A second sealing structure is formed between the outer circumferential surface of the sealing ring and the mounting hole, through which the limiting rod rotates and seals.

[0004] In the above technical solution, the spring is first compressed and rotated by pressing the limiting rod, so that the limiting rod is locked into the column, and then the pressure ring presses and fixes the filter bag. However, when the filter bag needs to be removed, after the limiting rod is rotated and disengaged from the column, the worker needs to pick up the pressure ring with one hand and remove the filter bag with the other hand. It is impossible to remove the pressure ring and the filter bag together, which increases the cumbersomeness of manual operation. Utility Model Content

[0031] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] refer to Figures 1-6 A filtration device includes a filter barrel 1, a filter bag 7, a fixing assembly 2, an elastic clamping assembly 3, and a cover 4 for covering the top of the filter barrel 1. The filter barrel 1 is provided with an inlet pipe 11 and an outlet pipe 12. The interior of the filter barrel 1 is provided with an mounting plate 14. The mounting plate 14 is provided with a through hole 141. An annular assembly 15 is provided on the wall of the through hole 141. The filter bag 7 has a handle 71. The upper edge of the filter bag 7 overlaps the annular assembly 15.

[0034] The fixing component 2 is located on the top of the mounting plate 14. The fixing component 2 is provided with a bayonet 22. The elastic pressing component 3 can be pressed and rotated to make the elastic pressing component 3 snap into the bayonet 22, thereby pressing and fixing the filter bag 7 onto the annular component 15.

[0035] The bottom of the elastic clamping component 3 is provided with a barb 35 for hooking the handle 71, and the barb 35 corresponds one-to-one with the handle 71; when the elastic clamping component 3 is disengaged from the latch 22, the barb 35 can be positioned below the handle 71 by rotating the elastic clamping component 3.

[0036] In this design, the worker first overlaps the upper edge of the filter bag 7 onto the annular assembly 15, then places the elastic clamping assembly 3 on the upper edge of the filter bag 7, and then presses and rotates the elastic clamping assembly 3 so that it can be engaged into the slot 22 of the fixing block 21. In this way, the elastic clamping assembly 3 can fix the filter bag 7 in place. Then, the cover 4 is placed on top of the filter tank 1. Next, the liquid to be filtered is introduced through the liquid inlet pipe 11, filtered by the filter bag 7, and discharged from the liquid outlet pipe 12. When the filter bag 7 needs to be disassembled and replaced, open the cover 4 and then press and rotate the elastic clamping component 3 to disengage it from the latch 22, thereby loosening the fixation on the filter bag 7. Then continue to rotate the elastic clamping component 3 so that the barb 35 is below the handle 71, lift the elastic clamping component 3, and let the barb 35 hook the handle 71, thereby lifting the filter bag 7 together and taking it out. In this way, it is more convenient and faster for workers to take out the filter bag 7.

[0037] In this embodiment, there are two handles 71, and the elastic pressing assembly 3 includes a connecting plate 32, a pressing member 36, a spring 34, and two vertically arranged movable rods 33;

[0038] Two movable rods 33 are movably inserted through the connecting plate 32, and the two movable rods 33 are spaced apart along the length of the connecting plate 32; a pressing plate 31 is provided at the top of each movable rod 33; a barb 35 is provided at the bottom of the two movable rods 33; a spring 34 is sleeved on the movable rods 33 and located between the pressing plate 31 and the connecting plate 32; a clamping member 36 is connected to the bottom of the connecting plate 32, and the clamping member 36 is used to press and fix the filter bag 7 onto the annular assembly 15; when the clamping member 36 presses and fixes the filter bag 7 onto the annular assembly 15, the height of the barb 35 is lower than the height of the handle 71;

[0039] The fixing component 2 includes two fixing blocks 21, and the bayonet 22 is provided on the two fixing blocks 21. The two fixing blocks 21 are rotationally symmetrical about the center of the through hole 141.

[0040] The pressing plate 31 can be pressed and rotated so that its two ends are respectively engaged in the two slots 22, thereby pressing and fixing the filter bag 7 onto the annular assembly 15 by the pressing member 36.

[0041] Specifically, after placing the upper edge of the filter bag 7 on the annular assembly 15, the clamping member 36 is placed on the upper edge of the filter bag 7, and then the pressing plate 31 is pressed. While the spring 34 is compressed, the pressing plate 31 is rotated so that the two ends of the pressing plate 31 enter the two slots 22 respectively. Then the worker releases his hand, using the slots 22 to prevent the pressing plate 31 from springing up, thereby allowing the clamping member 36 to press and fix the filter bag 7 on the annular assembly 15.

[0042] When it is necessary to remove the filter bag 7, press the pressing plate 31 again and rotate it in the opposite direction to when it was screwed into the latch 22. This way, the two ends of the pressing plate 31 can be disengaged from the latch 22. After the filter bag 7 is released, continue to rotate the pressing plate 31 so that the barb 35 is below the handle 71 of the filter bag 7. Then lift the pressing plate 31 to drive the barb 35 upward. This way, the barb 35 can hook the handle 71 and remove the filter bag 7 together.

[0043] Generally, when a worker presses the pressing plate 31, the palm of the worker contacts the top of the pressing plate 31, and then the worker applies downward force to press the pressing plate 31 to compress the spring 34. The pressing plate 31 is a plate, which can increase the contact area with the palm, thereby improving the comfort of pressing.

[0044] In this embodiment, the upper end of the movable rod 33 is rotatably connected to the bottom of the pressing plate 31. Rotating the upper end of the movable rod 33 to the bottom of the pressing plate 31 makes it easier for the worker to adjust the position of the hook 35 so that it can better hook the handle 71 when the pressing plate 31 is lifted.

[0045] Preferably, the annular component 15 includes an annular block 151, which is connected to the wall of the through hole 141;

[0046] The annular assembly 15 also includes a sealing ring (not shown in the figure), which is disposed on the annular block 151;

[0047] The through hole 141 is circular, and the clamping member 36 is annular.

[0048] Generally, the sealing ring is placed on the annular block 151. After the upper edge of the filter bag 7 is placed on the sealing ring, the filter bag 7 is pressed and fixed by the annular clamping member 36, and the sealing performance is improved by the sealing ring.

[0049] Preferably, it also includes an L-shaped rod 5, an installation block 13 is provided on the outside of the filter barrel 1, the vertical section of the L-shaped rod is rotatably connected to the installation block 13, the horizontal section of the L-shaped rod 5 is provided with a nut sleeve 51, a threaded rod 52 is installed in the nut sleeve 51, the upper end of the threaded rod 52 is provided with a manual turntable 53, and the lower end of the threaded rod 52 is connected to the cover body 4.

[0050] Specifically, when the cover 4 is to be placed on top of the filter barrel 1, the cover 4 is moved downward by rotating the manual turntable 53, so that the cover 4 presses on the top of the filter barrel 1. When the cover 4 needs to be opened, the cover 4 is moved upward by rotating the manual turntable 53, and then the vertical section of the L-shaped rod 5 is rotated to move the cover 4 away from the top of the filter barrel 1. This makes it easier for workers to install and remove the filter bag 7.

[0051] Preferably, it also includes a lifting eye bolt 6, and a plurality of first connecting blocks 41 are provided on the edge of the cover 4, and a second connecting block 16 corresponding to the first connecting blocks 41 is provided on the upper edge of the filter bucket 1;

[0052] The first connecting block 41 has a vertically penetrating first bolt hole (not shown in the figure), and the second connecting block 16 has a vertically penetrating second bolt hole (not shown in the figure). The eye bolt 6 corresponds one-to-one with the first connecting block 41, and the eye bolt 6 is used to pass through the first bolt hole and the second bolt hole. The cover 4 is fixed by passing the eye bolt 6 through the first bolt hole and the second bolt hole.

[0053] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
