Description
Technical Field
[0001] This utility model relates to the field of membrane separation technology, and in particular to an ultrafiltration membrane separation device. Background Technology
[0002] Ultrafiltration membrane separation devices are widely used in water treatment, chemical industry, food processing, and other fields. Their technological development is closely related to the upgrading of separation requirements. Early separation technologies suffered from low efficiency, high energy consumption, and insufficient precision. With advancements in membrane material science and preparation processes, ultrafiltration membranes, with their pore size range between microfiltration and nanofiltration, can achieve highly efficient retention of macromolecules, colloids, proteins, and microorganisms in solutions, while maintaining the permeability of solvents and small-molecule solutes. Current research on ultrafiltration membrane separation devices focuses on optimizing membrane module structure, improving antifouling performance, optimizing operating parameters, and integrating with other processes. This aims to address issues such as membrane fouling, rapid flux decline, and unstable separation efficiency that traditional devices often encounter when processing high-concentration and complex systems, thereby meeting the higher requirements of various industries for separation precision, processing efficiency, and economy. In existing ultrafiltration membrane separation devices, the vertically installed filter cartridge is difficult to fix. Generally, a simple bracket is set up to support the filter cartridge by connecting the pipes at the upper and lower ends. However, in actual use, the filter cartridge will fill with water during filtration, which increases its weight. This puts pressure on the lower pipe and also puts downward tension on the upper pipe. Over time, this can lead to leakage at the pipe connection and even damage to the pipe. Therefore, we propose an ultrafiltration membrane separation device. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an ultrafiltration membrane separation device, which provides support for each filter cartridge by setting a bracket corresponding to and matching the filter cartridge, so that it is not easy to compress and stretch the pipeline during use, thereby improving the service life of the pipeline.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An ultrafiltration membrane separation device includes a control mechanism, wherein the inner middle portion of the control mechanism is fixedly mounted. It is equipped with a filter mechanism, which is fixedly nested on the inner end side of the support mechanism; The support mechanism includes a bracket, a support surface is installed on the upper end of the bracket, and a slot is provided on the upper side of the support surface. The filter cartridge is fixed and supported by the bracket and the slot, making it more stable during filtration and improving the stability of the device during use. The filtration mechanism includes a filter cylinder, a lower connecting pipe at the lower end of the filter cylinder, a lower tube fixedly connected to the lower end of the lower connecting pipe, and an upper connecting pipe at the upper end of the filter cylinder. The upper end of the connecting tube is fixedly connected to the upper tube, the front end of the lower tube is provided with a liquid inlet, and the outer end of the filter cylinder is fixedly installed with an installation pad. By setting the installation pad, a fixing point is provided for the originally smooth filter cylinder, making the filter cylinder easier to fix and install, and improving the convenience of using the device. The filter cartridge passes through the slot, and the mounting pad is fixedly nested inside the slot.
[0005] Furthermore, the control mechanism includes a support plate, with support columns at the four lower corners of the support plate, and casters installed at the lower ends of the support columns. A support frame is fixedly installed at the upper end of the support plate, and a control box is fixedly installed on the inner side of the support frame. The casters facilitate the movement and transfer of the device, improving its ease of use.
[0006] Furthermore, the bracket is fixedly installed in the upper middle part of the support plate and the connection method is welding. By setting the bracket to be fixedly installed in the upper middle part of the support plate and the connection method is welding, the bracket is more stably installed on the support plate, so that it supports the filter cylinder and is not easy to shift, thereby improving the overall strength of the device and making the device more stable during use.
[0007] Furthermore, the number of the card slots and the mounting pads are the same and there are several of each, and several mounting pads are connected to the card slots respectively.
[0008] Furthermore, the mounting pad is made of rubber and has a frustum-shaped structure with its lower outer diameter smaller than the inner diameter of the slot and its upper outer diameter larger than the inner diameter of the slot.
[0009] Furthermore, there are two lower tubes, which intersect and are connected to the liquid inlet.
[0010] In summary, this utility model has the following beneficial effects: 1. By setting brackets and slots to fix and support the filter cartridge, it is made more stable during filtration, which improves the stability of the device during use. By setting mounting pads to provide fixing points for the originally smooth filter cartridge, the filter cartridge is easier to fix and install, which improves the convenience of the device during use. 2. The installation of casters facilitates movement and transportation of the device, improving its ease of use. The bracket is fixedly installed on the upper middle part of the support plate by welding, making the bracket more stable on the support plate and supporting the filter cylinder to prevent displacement. This improves the overall strength of the device and makes it more stable during use. Attached Figure Description

Detailed Implementation
[0013] The present invention will be further described in detail below with reference to the accompanying drawings.
[0014] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0015] Referring to Figures 1-4, a preferred embodiment of the present invention provides an ultrafiltration membrane separation device, including a control mechanism 1. A filter mechanism 2 is fixedly installed in the middle of the inner end of the control mechanism 1. It is nested on the inner end side of the support mechanism 3; The support mechanism 3 includes a bracket 301. A support surface 302 is mounted on the upper end of the bracket 301. A slot 303 is provided on the upper side of the support surface 302. The number of slots 303 and mounting pads 207 is the same, and there are several of each. Several mounting pads 207 are connected to the slots 303 respectively. The mounting pads 207 are made of rubber and have a frustum-shaped structure. The outer diameter of the lower end of the mounting pad is smaller than the inner diameter of the slot 303, and the outer diameter of the upper end is larger than the inner diameter of the slot 303. By setting the material of the mounting pads 207 to rubber and the frustum-shaped structure, the outer diameter of the lower end is smaller than the inner diameter of the slot 303, and the outer diameter of the upper end is larger than the inner diameter of the slot 303, it is easier for the mounting pads 207 to be nested with the slots 303, and they are less likely to shift after nesting, thus improving the stability of the device during use. By setting the bracket 301 and the slots 303, the mounting pads 207 are more likely to be nested with the slots 303, and they are less likely to shift after nesting, thus improving the stability of the device during use. The filter cartridge 201 is fixed and supported to make it more stable during filtration, thereby improving the stability of the device during use.
[0016] Referring to Figures 1-5, the filter mechanism 2 includes a filter cylinder 201. A lower connecting pipe 202 is provided at the lower end of the filter cylinder 201, and a lower pipe 203 is fixedly connected to the lower end of the lower connecting pipe 202. An upper connecting pipe 204 is provided at the upper end of the filter cylinder 201, and an upper pipe 205 is fixedly connected to the upper end of the upper connecting pipe 204. A liquid inlet 206 is provided at the front end of the lower pipe 203. A mounting pad 207 is fixedly installed on the outer end of the filter cylinder 201. The filter cylinder 201 passes through a slot 303, and the mounting pad 207 is fixedly nested inside the slot 303. There are two lower pipes 203, which intersect and connect to the liquid inlet 206. By setting two lower pipes 203 to intersect and connect to the liquid inlet 206, the device is easier to insert into the liquid inlet, improving the convenience of use. The mounting pad 207 makes the originally smooth filter cylinder 201... Providing a fixed mounting point makes it easier to fix and install the filter cartridge 201, improving the convenience of using the device.
[0017] Referring to Figures 1-2, the control mechanism 1 includes a support plate 101. Support columns 102 are provided at the four corners of the lower end of the support plate 101. Casters 103 are installed at the lower ends of the support columns 102. A support frame 104 is fixedly installed at the upper end of the support plate 101. A control box 105 is fixedly installed on the inner side of the support frame 104. The casters 103 facilitate the movement and transfer of the device, improving the convenience of using the device.
[0018] Referring to Figures 2-4, the bracket 301 is fixedly installed at the upper middle part of the support plate 101 by welding. Welding ensures that the bracket 301 is more securely mounted on the support plate 101, making it less likely to shift when supporting the filter cartridge 201, thus improving the overall strength of the device and making it more stable during use.
[0019] Specific implementation process: Align the mounting pad 207 at the outer end of the filter cartridge 201 with the groove on the support surface 302. 303. Because the mounting pad 207 is a frustum-shaped rubber structure, it can be tightly fixed by the elastic deformation of the rubber after nesting, preventing the filter cartridge 201 from shifting. The bracket 301 is fixed to the middle of the support plate 101 by welding, providing stable support for the filter assembly. The lower connecting pipe 202 is connected to the lower pipe 203. The two lower pipes 203 converge and connect to the liquid inlet 206 for introducing the liquid to be filtered. The upper connecting pipe 204 is connected to the upper pipe 205 for discharging the filtered liquid. The device is moved to the designated position by the moving wheels 103 at the lower end of the support plate 101. After positioning, the moving wheels 103 can be fixed as needed. The liquid to be filtered enters from the liquid inlet 206, is diverted by the two lower pipes 203 and then flows into the lower connecting pipe 202, entering the filter cartridge 201. The device is equipped with an ultrafiltration membrane. Under pressure, the liquid passes through the ultrafiltration membrane. Large molecules are trapped inside the membrane, forming a concentrate, while small molecules permeate through the membrane and are discharged from the lower tube 203 via the upper connecting pipe 204, becoming the filtrate. The filtrate is collected through the upper tube 205 and can be used directly or sent to subsequent processing stages. The concentrate can be discharged from the bottom of the filter cartridge 201 for recycling or further processing. The power system is shut off by controlling the control box 105 to stop the liquid input and disconnect the power supply to the device. If the ultrafiltration membrane needs to be replaced or cleaned, the filter cartridge 201 can be disassembled. Since the mounting pad 207 and the slot 303 are nested, maintenance is convenient. The rubber mounting pad 207 can withstand a certain amount of cleaning liquid, so frequent replacement is not required during maintenance. The control box 105 stabilizes the liquid flow and pressure to ensure that the filter cartridge 201 remains stable under the support of the bracket 301, preventing the device from shaking or leaking due to pressure fluctuations.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
