Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration membrane technology, and in particular to an ultrafiltration membrane module for wastewater filtration. Background Technology

[0002] Ultrafiltration membrane modules for wastewater filtration are usually an important component of wastewater treatment systems. They utilize the high-efficiency filtration performance of ultrafiltration membranes to remove suspended solids, colloids, bacteria, viruses, and some macromolecular substances from water, thereby purifying the water.

[0003] In existing wastewater filtration ultrafiltration membrane modules, the ultrafiltration membrane is usually placed inside a cylindrical tank, and the tank lid is used to seal the tank and fix the ultrafiltration membrane inside the tank. In order to ensure the airtightness during the filtration process and prevent wastewater leakage or external pollutants from entering, a sealing gasket is usually set inside the tank lid. This sealing gasket is usually fixed to the inner surface of the tank lid by adhesion or other means, and forms a tight sealing structure in contact with the tank body.

[0004] However, this design has a problem: with long-term use of the ultrafiltration membrane module, the sealing gasket may age, wear, or crack due to factors such as water pressure, chemicals, and repeated disassembly and assembly. In such cases, the sealing gasket needs to be replaced to ensure continued good sealing performance. However, since existing sealing gaskets are usually directly adhered to or fixed inside the lid, it is difficult for users to easily replace them after damage. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, the sealing gasket is usually directly adhered to or fixed inside the bucket lid, which makes it difficult for users to easily replace the sealing gasket after it is damaged.

[0015] The technical effect of adopting the above-mentioned further solution is that the second bolt can be embedded into the inside of the second threaded groove to fix the bucket lid 101 to the bucket body.

[0016] In a preferred embodiment, positioning grooves are provided on both sides of the inner wall of the barrel, and positioning columns are fixedly installed on both sides of the ultrafiltration membrane body.

[0017] The technical effect of adopting the above-mentioned further solution is that it allows the positioning post to be embedded into the positioning groove.

[0018] In a preferred embodiment, both positioning posts are matched with the positioning grooves, and push plates are movably embedded inside both positioning grooves.

[0019] The technical effect of adopting the above-mentioned further solution is that the positioning column can be pushed to slide inside the positioning groove by the push plate.

[0021] The technical effect of adopting the above-mentioned further solution is that the slider can be driven by the push plate to slide on the inner surface of the groove.

[0022] In a preferred embodiment: all four sliders are slidably connected to the inner surface of the groove, and a return spring is fixedly installed on the right side of each of the two push plates, with the other end of each return spring located inside the barrel.

[0023] The technical effect of adopting the above-mentioned further solution is that the return spring can be extended by pushing the push plate.

[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0025] This invention, through the design of the sealing gasket and cover plate structure, not only allows personnel to easily disassemble and replace the sealing gasket, greatly simplifying the gasket replacement process, but also enables operators to perform maintenance quickly and conveniently, saving time and labor costs. At the same time, the sealing gasket can cover the outer surface of the barrel to ensure that the liquid does not leak, greatly improving the sealing performance of the component. This solves the problem in the prior art that the sealing gasket is usually directly adhered to or fixed inside the barrel lid, which makes it difficult for users to easily replace the gasket after it is damaged.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0037] Example 1, please refer to Figure 1-8 This utility model provides a technical solution: an ultrafiltration membrane assembly for wastewater filtration, including a barrel body 1, an ultrafiltration membrane body 102 disposed inside the barrel body 1, a barrel cover 101 movably fitted on the left outer surface of the barrel body 1, and further including: a sealing gasket 103 disposed on the inner wall of the barrel cover 101, the sealing gasket 103 being movably fitted on the left outer surface of the barrel body 1; two hinges 104, both fixedly installed on the outer surface of the barrel cover 101, each hinge 104 being movably connected to a connecting post 105, and a cover plate 106 being fixedly installed on the opposite side of each connecting post 105; Both cover plates 106 are movably connected to the bottom of the bucket lid 101, and the bottom of the sealing gasket 103 is movably connected to the top of the two cover plates 106. Both sides of the inside of the two cover plates 106 are threaded with first bolts 108. Both sides of the bottom of the bucket lid 101 have two first threaded grooves 107. All four first bolts 108 are matched with the first threaded grooves 107. Both sides of the inside of the bucket lid 101 are threaded with second bolts 109. Both sides of the inside of the bucket body 1 have second threaded grooves 110. Both second threaded grooves 110 are matched with the second bolts 109.

[0038] In this embodiment, the operator first places the ultrafiltration membrane body 102 into the inside of the container 1, picks up the lid 101, places it on the left side of the container 1, and pushes the lid 101 to the right so that it fits onto the left outer surface of the container 1, while simultaneously allowing the sealing gasket 103 to cover the left outer surface of the container 1. Then, the operator can rotate the second bolt 109 to embed it into the second threaded groove 110 inside the container 1, thereby fixing the lid 101 to the container 1. When it is necessary to replace the sealing gasket 103, the operator can reverse the second bolt 109 to disengage it from the second threaded groove 110, and simultaneously pull the second bolt 109 out of the lid 101. Then, the operator pulls the lid 101 to the left so that it can move the sealing gasket 103 away from the container 1. Finally, the operator can reverse the first bolt. 108, allowing it to disengage from the first threaded groove 107, and by pulling the connecting column 105 outward, it can be flipped via the hinge 104. Simultaneously, the connecting column 105 flips, causing the cover plate 106 to move synchronously, thereby allowing the top of the cover plate 106 to detach from the bottom of the bucket lid 101 and the sealing gasket 103. Then, personnel can remove the sealing gasket 103 for replacement. The structure of the sealing gasket 103 and the cover plate 106 not only makes it easy for personnel to disassemble and replace the sealing gasket 103, greatly simplifying the replacement process, but also allows operators to perform maintenance quickly and conveniently, saving time and labor costs. At the same time, the sealing gasket 103 can cover the outer surface of the bucket body 1 to ensure that the liquid does not leak, greatly improving the sealing performance of the component.

[0039] Example 2, as Figure 1-8 As shown, positioning grooves 2 are provided on both sides of the inner wall of the barrel 1. Positioning posts 201 are fixedly installed on both sides of the ultrafiltration membrane body 102. The two positioning posts 201 are matched with the positioning grooves 2. Push plates 202 are movably embedded in the interior of the two positioning grooves 2. The right side of the two positioning posts 201 is movably connected to the left side of the push plates 202. Slider blocks 203 are fixedly installed on both sides of the two push plates 202. Four sliding grooves 204 are provided inside the barrel 1. The four sliders 203 are slidably connected to the inner surface of the sliding grooves 204. Reset springs 205 are fixedly installed on the right side of the two push plates 202. The other end of the two reset springs 205 is located inside the barrel 1.

[0040] In this embodiment, the operator can first place the ultrafiltration membrane body 102 into the inside of the container 1, so that the positioning post 201 can be embedded in the positioning groove 2, and the positioning post 201 can fit against the left side of the push plate 202. When it is necessary to disassemble the ultrafiltration membrane body 102, the operator can push the push plate 202 to the left, so that the push plate 202 can push the positioning post 201 to slide to the left on the inner surface of the positioning groove 2, thereby pushing one end of the ultrafiltration membrane body 102 out of the container 1. When the push plate 202 moves, it can drive the slider 203 to slide on the inner surface of the slide groove 204, and at the same time pull... The resetting spring 205 extends, allowing personnel to pull one end of the ultrafiltration membrane body 102 and remove it from the inside of the container 1 to complete the disassembly of the ultrafiltration membrane body 102. The positioning groove 2 and the push plate 202 structure not only allow personnel to easily push one end of the ultrafiltration membrane body 102 out of the container 1, but also make the disassembly process very intuitive and simple. Personnel only need to push the push plate 202 without complicated tools or operating steps, further reducing the difficulty of manual operation. At the same time, the cooperative design of the positioning column 201 and the positioning groove 2 ensures the stable placement and precise alignment of the ultrafiltration membrane body 102 inside the container 1.

[0041] Working principle: In use, the operator first places the ultrafiltration membrane body 102 into the container 1, picks up the lid 101, places it on the left side of the container 1, and pushes the lid 101 to the right so that it fits onto the left outer surface of the container 1, while simultaneously allowing the sealing gasket 103 to cover the left outer surface of the container 1. Then, the operator can rotate the second bolt 109 to embed it into the second threaded groove 110 inside the container 1, thereby fixing the lid 101 to the container 1. When it is necessary to replace the sealing gasket 103, the operator can reverse the second bolt 109 to disengage it from the second threaded groove 110, and simultaneously pull the second bolt 109 out of the lid 101. Then, pull the lid 101 to the left to move the sealing gasket 103 away from the container 1. Then, the operator can reverse the first bolt 109 to replace the sealing gasket 103. Bolt 108 is used to disengage it from the first threaded groove 107. Pulling the connecting column 105 outward allows it to flip via hinge 104. As the connecting column 105 flips, it drives the cover plate 106 to move synchronously, allowing the top of the cover plate 106 to detach from the bottom of the lid 101 and the sealing gasket 103. Then, personnel can remove the sealing gasket 103 for replacement. The structure of the sealing gasket 103 and the cover plate 106 not only makes it easy for personnel to disassemble and replace the sealing gasket 103, greatly simplifying the replacement process, but also allows operators to perform maintenance quickly and conveniently, saving time and labor costs. At the same time, the sealing gasket 103 can cover the outer surface of the barrel 1 to ensure that the liquid does not leak, greatly improving the sealing performance of the component. In use, the operator first places the ultrafiltration membrane body 102 into the container 1, ensuring that the positioning post 201 is embedded in the positioning groove 2 and that it fits against the left side of the push plate 202. When disassembly of the ultrafiltration membrane body 102 is required, the operator pushes the push plate 202 to the left, causing it to slide the positioning post 201 to the left on the inner surface of the positioning groove 2. This pushes one end of the ultrafiltration membrane body 102 out of the container 1. As the push plate 202 moves, it causes the slider 203 to slide on the inner surface of the groove 204, simultaneously pulling... The resetting spring 205 extends, allowing personnel to pull one end of the ultrafiltration membrane body 102 and remove it from the inside of the container 1 to complete the disassembly of the ultrafiltration membrane body 102. The positioning groove 2 and the push plate 202 structure not only allow personnel to easily push one end of the ultrafiltration membrane body 102 out of the container 1, but also make the disassembly process very intuitive and simple. Personnel only need to push the push plate 202 without complicated tools or operating steps, further reducing the difficulty of manual operation. At the same time, the cooperative design of the positioning column 201 and the positioning groove 2 ensures the stable placement and precise alignment of the ultrafiltration membrane body 102 inside the container 1.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
