Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a quick-assembly and disassembly structure suitable for filter elements. Background Technology

[0002] Chinese patent CN220834366U discloses a multi-bag filter. The technical solution includes a filter tank and connecting pipes. A drain pipe is fixedly connected to the bottom surface of the filter tank. A filter device is movably connected inside the filter tank. A locking device is movably connected to the top of the filter tank. A connecting cover plate is movably connected to the top surface of the filter tank. The connecting pipe is fixedly connected to the lower surface of the filter tank. This multi-bag filter, by incorporating bag filter elements, connecting devices, a metal block, and a limiting arc plate, allows the limiting arc plate to move downwards and slide downwards on the surface of a metal insert, connecting the limiting arc plate and the top surface of the connecting device. This limits the height of the bag filter elements, making replacement quick and convenient, shortening the replacement time, and increasing the service life of the device.

[0003] This technical solution also has the following shortcomings: When installing the filter device, one end of the metal block must first be fixed in place with screws and nuts, and then the other end of the insert plate must be placed in place and fixed by tightening bolts. During this fixing process, attention must also be paid to whether the insert rod plays a limiting role. This installation process involves many steps and is relatively cumbersome. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a quick disassembly and assembly structure suitable for filter elements, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model discloses a quick-assembly and disassembly structure suitable for filter elements. The technical solution includes a filter tank, with a partition inside the filter tank. The partition has multiple fixing devices, each including a frame. The frame and the partition are detachably connected. The frame and the partition are threaded with lifting eye bolts. There are multiple lifting eye bolts arranged in a ring on the partition. The frame contains filter media, and a pressure cap is located above the filter media. The edge of the pressure cap has multiple hanging ears arranged in a ring on the edge of the pressure cap. The lifting eye bolts and the hanging ears cooperate and press against each other.

[0006] As a preferred technical solution of this utility model, the upper end of the frame has an end plate, and the surface of the end plate has a countersunk hole, and the countersunk hole contains a countersunk screw.

[0007] As a preferred technical solution of this utility model, a plurality of first threaded holes are opened on the surface of the partition plate, and the positions of the threaded holes correspond to the countersunk screws. The countersunk screws detachably fix the end plate to the surface of the partition plate, and there is a sealing gasket between the end plate and the partition plate.

[0008] As a preferred technical solution of this utility model, the end plate is also provided with a through hole, and the partition plate is also provided with a second threaded hole, and the positions of the through hole and the second threaded hole are corresponding. The eye bolt passes through the through hole and the second threaded hole and is threadedly connected to the partition plate.

[0009] As a preferred technical solution of this utility model, the number of hanging ears is the same as that of the eye bolts, the hanging ears are L-shaped, and the screw of the eye bolts contacts the inside of the hanging ears.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the pressure cap can be rotated in one direction to separate the hanging ear from the lifting eye bolt. By holding the handle, the pressure cap can be removed to replace the old filter material inside the frame with the new filter material. Then the pressure cap is put back on and the lifting eye bolt is tightened to press the hanging ear with the pressing end, thus completing the replacement of the filter material. This technical solution has a simple structure, is quick to replace, and reduces the difficulty of replacement operation. Attached Figure Description

[0016] 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. Example 1

[0017] like Figures 1 to 4As shown, this utility model discloses a quick-assembly and disassembly structure suitable for filter elements. The technical solution includes a filter tank 1, with a partition 2 inside the filter tank 1. Multiple fixing devices are provided on the partition 2, each including a frame 3. An end plate 301 is located at the upper end of the frame 3. A countersunk hole is formed on the surface of the end plate 301, and a countersunk screw 7 is placed inside the countersunk hole. Multiple first threaded holes are formed on the surface of the partition 2, and the positions of the threaded holes correspond to the countersunk screws 7. The countersunk screws 7 detachably fix the end plate 301 to the surface of the partition 2. A sealing gasket 9 is provided between the end plate 301 and the partition 2. The end plate 301 also has a through hole, and the partition 2 also has a first threaded hole. Two threaded holes are provided, with the through hole and the second threaded hole corresponding to each other. The eye bolt 6 passes through the through hole and the second threaded hole and is threaded to the partition plate 2. There are multiple eye bolts 6 arranged in a ring on the partition plate 2. The frame 3 contains filter media 8. The end of the filter media 8 has a clamping edge 801. There is a pressure cap 4 above the filter media 8. The edge of the pressure cap 4 is provided with a hanging ear 5. The number of hanging ears 5 is the same as that of the eye bolts 6 and they are arranged in a ring to the edge of the pressure cap 4. The hanging ear 5 has an L-shaped structure. The threaded part of the eye bolt 6 contacts the inside of the hanging ear 5. The clamping edge 801 is pressed between the pressure cap 4 and the end plate 301. The eye bolts 6 and the hanging ears 5 cooperate and press against each other to fix the filter media 8.

[0018] The working principle of this utility model is as follows: This utility model is mainly used for the quick disassembly and replacement of filter media 8. When it is necessary to replace filter media 8, first loosen the lifting eye bolt 6. At this time, the cover 4 can be rotated in one direction. When rotating, the hanging ear 5 moves away from the lifting eye bolt 6. Then, hold the handle 401 to remove the cover 4. After that, take out the old filter media 8 from the inside of the frame 3 and place the new filter media 8 inside the frame 3. Then put the cover 4 back on and rotate the cover 4 in the opposite direction so that the hanging ear 5 contacts the lifting eye bolt 6. Then tighten the lifting eye bolt 6 so that the pressing end 601 presses the hanging ear 5, thus completing the replacement of filter media 8. The structure is simple and the replacement is quick.

[0019] The mechanical connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It is common knowledge.

[0020] Components not described in detail in this article are existing technologies.
