Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a membrane treatment device for industrial wastewater treatment. Background Technology

[0002] As industrial production continues to expand, wastewater discharge increases significantly. The wastewater contains complex pollutants such as organic matter and heavy metals. Environmental regulations are becoming increasingly stringent on wastewater discharge standards, while the demand for water resource recycling is constantly increasing. Therefore, membrane treatment devices for industrial wastewater treatment are being established to efficiently remove various pollutants from wastewater by utilizing the selective separation function of membranes, thereby achieving deep water purification and helping industrial wastewater meet discharge standards.

[0003] A search revealed Chinese patent publication number CN217498805U, which discloses a membrane treatment device for industrial wastewater treatment. The device includes a wastewater treatment tank and a drain pipe located at the top right side of the tank. An installation frame is movably installed inside the wastewater treatment tank, and a membrane module is fixedly installed at the bottom of the frame. Lifting seats are slidably installed on the inner walls of both sides of the wastewater treatment tank. A transverse sleeve is fixedly connected to the side of each lifting seat that is close to the other. A movable connecting rod is movably connected to the inner end of the transverse sleeve, and both ends of the installation frame are fixedly connected to one end of the movable connecting rod. This membrane treatment device for industrial wastewater treatment not only allows for height adjustment of the membrane module but also left and right position adjustment. This avoids the drawbacks of previous fixed membrane modules, which made it difficult to adjust the height and position according to actual needs. It significantly improves and adjusts the range of membrane treatment, and its simple structure makes it easy to adjust and use.

[0004] The aforementioned patent has the following shortcomings: Since the filter membrane of the existing device is mostly located inside the device, maintenance and replacement require entering the interior through the manhole. This not only restricts the work activities of maintenance personnel and increases the difficulty of operation, but also may pose a safety risk due to contact with residual pollutants, causing many inconveniences for the regular maintenance and replacement of the filter membrane.

[0005] Therefore, a membrane treatment device for industrial wastewater treatment is proposed. Utility Model Content

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example 1: As Figures 1 to 5 As shown, a membrane treatment device for industrial wastewater treatment includes a water tank 1, and further includes: Sedimentation hopper 10 is fixed to the bottom of water tank 1, and a support frame 2 is fixed to the bottom of sedimentation hopper 10; A partition 11 is fixed to the bottom of the water tank 1. A filter membrane 8 is installed above the partition 11, and a mounting bracket 6 is installed above the filter membrane 8. The lifting structure 7 is set on one side of the water tank 1. The lifting structure 7 includes a fixed frame 701 fixed on one side of the water tank 1. A guide rod 702 is slidably connected to the top of the fixed frame 701. A movable frame 707 connected to the mounting frame 6 is fixed to the top of the guide rod 702. A power component is set at the bottom of the movable frame 707. The mounting structure 9 for mounting the filter membrane 8 is provided at both ends of the filter membrane 8; The slag discharge structure 3, used for centralized separation of wastewater sediments, is located at the bottom of the sedimentation hopper 10.

[0026] A sewage pipe 4 is fixed to one side of the sedimentation tank 10, a clean water pipe 5 is fixed to one side of the water tank 1, a pressure relief pipe 12 is fixed to one side of the top of the partition 11, and a pressure relief valve 13 is installed on one side of the pressure relief pipe 12.

[0027] In this embodiment, wastewater is introduced into the water tank 1 through the sewage pipe 4. Large particles of sediment in the wastewater settle to the bottom of the sedimentation hopper 10 and are filtered through the filter membrane 8. The filtered clean water is discharged through the clean water pipe 5. If the pressure inside the water tank 1 is too high during the wastewater treatment process, the pressure relief valve 13 can be opened to allow the excess wastewater to be discharged through the pressure relief pipe 12, preventing the filter membrane 8 from bursting.

[0028] like Figures 1 to 5 As shown, the power assembly includes a lifting sleeve 706 fixed inside the bottom of the movable frame 707. A threaded sleeve 703 is fixed inside the bottom of the lifting sleeve 706. A drive motor 704 is installed at the bottom of the fixed frame 701. A lead screw 705 connected to the threaded sleeve 703 is fixed at the end of the output shaft of the drive motor 704. Two sets of guide rods 702 are provided, and the guide rods 702 are symmetrically distributed on the vertical center line of the movable frame 707.

[0029] In this embodiment, when the filter membrane 8 needs to be maintained or replaced, the drive motor 704 is started to drive the lead screw 705 to rotate. Then the screw sleeve 703 moves upward with the rotation of the lead screw 705, which in turn causes the lifting sleeve 706 to push the moving frame 707 to rise vertically. This causes the mounting frame 6 connected to the moving frame 707 to move synchronously, so that the filter membrane 8 gradually leaves the inside of the water tank 1 and is fully exposed in the operating space, providing convenient conditions for the maintenance and replacement of the filter membrane 8.

[0030] Example 2: A membrane treatment device for industrial wastewater treatment. This example is an improvement on Example 1, as follows: Figures 1 to 5As shown, the slag discharge structure 3 includes a slag discharge pipe 307 fixed to the bottom of the sedimentation hopper 10. A reduction motor 308 is fixed to one side of the slag discharge pipe 307. An extrusion shaft 304 connected to the output shaft end of the reduction motor 308 is rotatably connected inside the slag discharge pipe 307. A spiral blade 306 is fixed to the outside of the extrusion shaft 304. A filter cylinder 301 is fixed at the middle section of the slag discharge pipe 307. An outer shell 302 fixedly connected to the slag discharge pipe 307 is sleeved on the outside of the filter cylinder 301. A drain pipe 305 is fixed to one side of the bottom end of the outer shell 302. A cover 303 is fixed to one side of the slag discharge pipe 307 by bolts. The front cross-section of the extrusion shaft 304 is a frustum-shaped structure. The extrusion shaft 304 and the spiral blade 306 are welded together as an integral structure.

[0031] In this embodiment, when the sediment in the sedimentation hopper 10 accumulates to a certain amount, the speed reduction motor 308 is started to drive the extrusion shaft 304 to rotate, so that the spiral blades 306 push the sediment towards the outlet end of the slag discharge pipe 307. At the same time, the extrusion shaft 304, whose diameter gradually increases, extrudes the sediment, so that the water in the sediment is squeezed out through the filter cylinder 301. The cover 303 is opened to discharge the residue after extrusion. To a certain extent, the centralized separation and dehydration treatment of the sediment is achieved, reducing the risk of secondary pollution.

[0032] like Figures 2 to 3 As shown, the installation structure 9 includes a mesh frame shell 901 fixed to the outside of the filter membrane 8. A tube 904 is fixed to the bottom end of the mesh frame shell 901, and a sealing gasket 906 is fixed to the bottom end of the tube 904. A plug-in seat 905 fixedly connected to the partition plate 11 is sleeved on the outside of the tube 904. A mounting shell 903 is fixed to the top of the mesh frame shell 901. A mounting seat 902 fixedly connected to the mounting frame 6 is threaded to the outside of the mounting shell 903. The tube 904 extends through the partition plate 11 into the interior of the plug-in seat 905, and a plug-in connection is formed between the tube 904 and the plug-in seat 905.

[0033] In this embodiment, when the filter membrane 8 needs to be installed, the structure of the filter membrane 8 is reinforced by the mesh frame shell 901. The mounting shell 903 is aligned and inserted into the mounting base 902. Then, the mounting shell 903 is rotated to make the two threadedly connected and fixed. The filter membrane 8 is installed at the bottom of the mounting frame 6. The lifting structure 7 drives the mounting frame 6 to move down so that the insertion tube 904 is aligned and inserted into the insertion base 905, thereby achieving the sealing and fixing of the bottom of the filter membrane 8.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
