Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ultrafiltration water treatment equipment, and in particular to an ultrafiltration water treatment device. Background Technology
[0002] Ultrafiltration water treatment equipment is a membrane separation process driven by pressure. Through the micropores on the membrane surface, particles and impurities with a diameter between 0.002-0.1μm can be retained. It can effectively remove colloids, silicon, proteins, microorganisms and macromolecular organic matter from water. When a liquid mixture flows through the membrane surface under a certain pressure, the solvent and small molecules permeate through the membrane, while large molecules are retained, thereby achieving the purpose of separation and purification based on size and intermolecular distance.
[0003] Chinese utility model patent CN214327334U discloses an ultrafiltration water treatment device, comprising a frame, a control box, and support feet. The control box is fixedly connected to the right side of the frame, the support feet are fixedly connected to the lower end of the frame, the motor box is fixedly connected to the left side of the frame, a filter is fixedly connected to the middle of the frame, an outlet pipe is fixedly connected to the upper end of the filter, a valve is fixedly connected to the left side of the outlet pipe, and an inlet pipe is fixedly connected to the lower end of the filter. This utility model, by setting up a filter screen, activated carbon, and a filter layer, allows the filter to absorb impurities in the water through the filter screen in actual use, preventing impurities in the water from clogging the filter and enabling the filter to function normally.
[0004] However, the filter screen inside the filter needs to be replaced regularly. Since it is located inside the filter, it is time-consuming, labor-intensive, and inconvenient for personnel to replace. At the same time, the entire filtration process needs to be stopped during the replacement process, which increases the overall maintenance time and affects the overall filtration efficiency. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an ultrafiltration water treatment device.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an ultrafiltration water treatment device, comprising a frame and filters disposed therein, wherein the filters are arranged in several groups, the lower end of each group of filters is connected to an inlet pipe, the upper end of each group of filters is connected to an outlet pipe, a flow pipe is disposed on the frame opposite to the inlet pipe, a transfer pipe is disposed between the inlet pipe and the flow pipe, a filter screen is disposed inside the transfer pipe, and branch pipes are respectively connected to the opposite ends of the inlet pipe and the flow pipe through a reversing valve, and two groups of branch pipes are disposed opposite to each other, and a transfer pipe with a filter screen is also disposed between the two groups of branch pipes.
[0007] Preferably, a limiting ring is provided on the inner wall of the opposite end of the water inlet pipe and the flow pipe, and the opposite end of the two sets of branch pipes, and a connecting pipe is slidably provided inside the limiting ring along the length direction of the water inlet pipe.
[0008] Preferably, a drive motor is provided on the outer wall of the flow pipe, and a drive motor is provided on the outer wall of a group of branch pipes. The output shafts of the drive motor and the drive motor are respectively connected to a bidirectional screw and a bidirectional screw. Connecting blocks are slidably provided at both ends of the bidirectional screw and the bidirectional screw.

[0011] Preferably, an observation window is embedded in the outer wall of the transfer tube.
[0012] The beneficial effects of this utility model are as follows: By setting a flow pipe on the frame opposite to the inlet pipe, and setting a limiting ring at the near end of the inlet pipe and the flow pipe, a connecting pipe is slidably set inside the limiting ring. A transfer pipe with a filter screen is placed between the two sets of connecting pipes. A drive motor is connected to a double-acting screw, and a connecting block is slidably set on the double-acting screw. A set of connecting blocks is connected to a set of connecting pipes. Compared with the prior art, this utility model can filter the inlet water by placing a transfer pipe with a filter screen at the inlet pipe, eliminating the need to place each set of filters one by one, reducing the amount of labor required for replacement, and saving costs. At the same time, branch pipes are set on the inlet pipe and the flow pipe respectively through a reversing valve. A limiting ring is also set at the near end of the two sets of branch pipes, and a connecting pipe is slidably set inside the limiting ring. A second drive motor is set on the outer wall of a set of branch pipes, and the second drive motor is connected to a second double-acting screw. A connecting block is also slidably set on the second double-acting screw. Thus, personnel do not need to stop the overall filtration work to replace the filter screen, avoiding the impact on the efficiency of the overall filtration work. Attached Figure Description

[0022] like Figures 1 to 4As shown, an ultrafiltration water treatment device includes a frame 1 and filters 2 disposed inside it. Several groups of filters 2 are arranged, with the lower end of each group connected to an inlet pipe 3 and the upper end connected to an outlet pipe 4. A flow pipe 5 is disposed on the lower left side of the frame 1, opposite to the inlet pipe 3. A transfer pipe 6 is disposed between the flow pipe 5 and the inlet pipe 3, and a filter screen 7 is disposed inside the transfer pipe 6. Branch pipes 9 are connected to the opposite ends of the inlet pipe 3 and the flow pipe 5 via reversing valves 8. Two sets of branch pipes 9 are arranged opposite each other. A transfer pipe 6 with a filter screen 7 is also disposed between the two sets of branch pipes 9. The inner walls of the opposite ends of the inlet pipe 3 and the flow pipe 5, and the opposite ends of the two sets of branch pipes 9, are respectively provided with... A limiting ring 10 has a connecting pipe 11 that slides horizontally along the length of the inlet pipe 3 on its inner wall. In this embodiment, the connecting pipe 11 has an I-shaped cross-section. A sealing ring 17 is embedded on the side of the limiting rings 10 that are far apart from each other. Sealing rings 18 are embedded on the outer walls of the left and right ends of the transfer pipe 6. A drive motor 12 is installed on the outer wall of the flow pipe 5, and a drive motor 13 is installed on the outer wall of the left branch pipe 9. The output shafts of drive motors 12 and 13 are respectively connected to bidirectional screws 14 and 15. The bidirectional screws 14 and 15 are arranged in parallel, and connecting blocks 16 are slidably installed at their left and right ends. Figures 1 to 2 As shown, the four sets of connecting blocks 16 are respectively connected to the front outer walls of the four sets of connecting pipes 11, and an arc-shaped alignment groove 19 is provided at the lower end of the connecting block 16. The purpose of the alignment groove 19 is to place the side end of the transfer pipe 6. An observation window 20 is embedded in the outer wall of the transfer pipe 6 to facilitate personnel to check the condition of the filter screen 7 inside the transfer pipe 6.
[0023] When personnel replace the transfer pipe 6 between the flow pipe 5 and the inlet pipe 3, the two sets of reversing valves 8 are controlled to allow water in the flow pipe 5 to enter the branch pipe 9 and pass through the transfer pipe 6 between the two sets of branch pipes 9. The water is then filtered by the filter screen 7 in the transfer pipe 6 between the two sets of branch pipes 9. Then, the drive motor 12 is controlled to rotate forward, causing the connecting blocks 16 of the two sets of pipes to move away from each other, pushing the two sets of connecting pipes 11 away from the outer wall of the transfer pipe 6 between the flow pipe 5 and the inlet pipe 3. Personnel can then remove and replace the new transfer pipe 6. When too much impurity accumulates in the transfer pipe 6 between the two sets of branch pipes 9, causing a blockage, the two sets of reversing valves 8 are controlled to prevent water in the flow pipe 5 from entering the branch pipe 9 and instead flow into the transfer pipe 6 between the flow pipe 5 and the inlet pipe 3. The drive motor 13 is then started to rotate forward, causing the two sets of connecting pipes 11 on the branch pipe 9 to move away from each other. Personnel can then remove and replace the pipe without stopping the overall filtration process.
[0024] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
