Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration membrane technology, and in particular to an ultrafiltration membrane housing with ultrafiltration membrane cleaning function. Background Technology

[0002] In today's era of widespread filtration technology, ultrafiltration membranes play a crucial role as key filtration elements in various fields, including drinking water purification, material separation in industrial production, and wastewater treatment. Ultrafiltration membranes can efficiently intercept impurities in water, such as bacteria, colloids, and large organic molecules, providing pure liquids that meet standards for various industries. However, during long-term use, ultrafiltration membranes inevitably become contaminated with various pollutants, such as suspended solids, viscous substances secreted by microorganisms, and persistent organic matter. These pollutants gradually clog the membrane pores, reducing the membrane's filtration performance, leading to a significant decrease in water production and a deterioration in filtration efficiency. Therefore, regular cleaning is essential to restore the performance of ultrafiltration membranes.

[0003] Currently, most ultrafiltration membrane housings use a built-in filter cartridge structure. When cleaning the ultrafiltration membrane is required, the filter cartridge must be removed from the housing. This removal process is often extremely complex, involving the disassembly of multiple components, and requires operators with specialized skills and extensive experience. Moreover, due to the relatively fragile structure of the ultrafiltration membrane itself, the filter cartridge is easily damaged due to careless operation, improper tool use, or external impact during disassembly. Once the filter cartridge is damaged, it not only directly affects its filtration efficiency and shortens its service life, but also requires additional investment for replacement, significantly increasing operating costs and maintenance difficulty.

[0004] The purpose of this invention is to provide an ultrafiltration membrane housing with an ultrafiltration membrane cleaning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution, which includes a shell tank body, a pair of mounting brackets symmetrically arranged on the top of the shell tank body, a drain port at the bottom of the shell tank body, a detachable sealing cap on the drain port, a water inlet at the lower part of one side of the outer wall of the shell tank body, an external pressure ultrafiltration membrane body movably arranged inside the shell tank body, a transmission assembly on one side of the shell tank body, the transmission assembly being drively connected to the external pressure ultrafiltration membrane body, and a cleaning assembly also being arranged inside the shell tank body, the cleaning assembly being covered on the outside of the external pressure ultrafiltration membrane body.

[0006] As a preferred embodiment of this utility model, a water outlet pipe is provided at the top of the external pressure ultrafiltration membrane body. The water outlet pipe is mounted on the top of the shell tank body via a first sealing bearing.

Several delivery pipes are disposed at the bottom of the distribution plate, and several nozzles are disposed on each delivery pipe, with the nozzles aligned with the external pressure ultrafiltration membrane body. A ring-shaped base plate is disposed at the bottom of the several delivery pipes, and several support feet are disposed at the bottom of the ring-shaped base plate. A water inlet pipe is disposed at the top of the distribution plate, and a pump body is disposed at the top of another mounting bracket.

[0010] As a preferred embodiment of this utility model, a support block is provided on the top of the shell tank body, an L-shaped tube is provided on the top of the support block, the top of the water outlet pipe is located inside the L-shaped tube, a sealing ring is provided on the inner wall of the L-shaped tube, and a flange is provided on the port of the L-shaped tube away from the water outlet pipe.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] 1. This utility model uses a cleaning component and a transmission component in combination. The pump body sprays the cleaning liquid through the distribution plate, delivery pipe and nozzle onto the external pressure ultrafiltration membrane body.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figures 1-9 As shown, the present invention proposes an ultrafiltration membrane housing with ultrafiltration membrane cleaning function, which includes a housing body 1 and various internal and external components. These components cooperate with each other to realize the normal operation and efficient cleaning and maintenance of the ultrafiltration membrane.

[0026] An outlet pipe 20 is provided at the top of the external pressure ultrafiltration membrane body 2. The outlet pipe 20 is installed at the top of the shell tank body 1 through a first sealing bearing 21. This connection method ensures that the outlet pipe 20 can rotate freely relative to the shell tank body 1, and also achieves good sealing through the first sealing bearing 21 to prevent liquid leakage inside the shell tank body 1. A transmission gear 22 is provided on a section of the wall outside the shell tank body 1 of the outlet pipe 20, which is used to cooperate with other transmission components to realize the rotation of the external pressure ultrafiltration membrane body 2. A rotating shaft 23 is provided at the bottom of the external pressure ultrafiltration membrane body 2. The rotating shaft 23 is movably mounted on the bottom plate of the shell tank body 1 through a second sealing bearing 25. Similarly, the second sealing bearing 25 ensures that the rotating shaft 23 can rotate and is sealed to prevent liquid leakage from the bottom. A transmission gear 3 24 is provided on a section of the wall outside the shell tank body 1 of the rotating shaft 23, which is used to work in conjunction with other transmission components.

[0027] A pair of mounting plates 11 are symmetrically arranged on one side of the outer wall of the shell tank body 1. The transmission shaft 31 in the transmission assembly 3 is movably arranged between the two mounting plates 11 through a pair of second bearing seats 30, so as to realize the rotatable installation of the transmission shaft 31. A pair of transmission gears 32 are arranged on the transmission shaft 31. The two transmission gears 32 are respectively meshed with the transmission gears 17 at the top and bottom of the shell tank body 1. The top and bottom of the shell tank body 1 are symmetrically arranged with rotating shafts 16. Both rotating shafts 16 are movably arranged on the shell tank body 1 through the first bearing seat 15. The rotating shafts 16 are equipped with transmission gears 17. The top transmission gear 17 is meshed with the transmission gear 22 on the water outlet pipe 20 at the top of the external pressure ultrafiltration membrane body 2. The bottom transmission gear 17 is meshed with the transmission gear 24 on the rotating shaft 23 at the bottom of the external pressure ultrafiltration membrane body 2. When the motor 34 starts and drives the transmission shaft 31 to rotate, the external pressure ultrafiltration membrane body 2 is finally driven to rotate through a series of meshing transmissions between gears. One of the mounting brackets 10 has a motor 34 mounted on its top. The drive end of the motor 34 is connected to the top of the drive shaft 31 via a coupling 33, ensuring that the power of the motor 34 is stably transmitted to the drive shaft 31.

[0028] The cleaning component 4 includes a distribution plate 40 disposed inside the shell tank body 1. Several delivery pipes 41 are disposed at the bottom of the distribution plate 40. Several nozzles 42 are disposed on each delivery pipe 41 and are aligned with the external pressure ultrafiltration membrane body 2 for spraying cleaning liquid to rinse the external pressure ultrafiltration membrane body 2. A ring base plate 46 is disposed at the bottom of the several delivery pipes 41. Several support feet 44 are disposed at the bottom of the ring base plate 46, which support the cleaning component 4 inside the shell tank body 1 to ensure stable installation. A water inlet pipe 43 is disposed at the top of the distribution plate 40. A pump body 45 is disposed at the top of another mounting bracket 10. The output end of the pump body 45 is connected to the port of the water inlet pipe 43. When the pump body 45 is started, the cleaning liquid can be delivered to the distribution plate 40 through the water inlet pipe 43 and then sprayed out through the delivery pipes 41 and nozzles 42.

[0029] A support block 5 is installed on the top of the shell tank body 1, and an L-shaped tube 50 is installed on the top of the support block 5. The top of the outlet pipe 20 of the external pressure ultrafiltration membrane body 2 is located inside the L-shaped tube 50. A sealing ring 52 is installed on the inner wall of the L-shaped tube 50 to further enhance the sealing effect and prevent liquid from leaking from the connection between the outlet pipe 20 and the L-shaped tube 50. A flange 51 is installed on the port of the L-shaped tube 50 away from the outlet pipe 20 to facilitate connection with the subsequent pipeline system and realize the transportation of ultrafiltration water.

[0030] A drain port 12 is provided at the bottom of the shell body 1, and a detachable sealing cover 13 is provided on the drain port 12. When cleaning the ultrafiltration membrane, the sealing cover 13 is opened to facilitate the discharge of the cleaned dirt from the drain port 12. After cleaning, the sealing cover 13 can be reinstalled to ensure the airtightness of the shell body 1 and meet the normal working requirements of the ultrafiltration membrane. A water inlet 14 is provided on the lower side of one outer wall of the shell body 1 to introduce the liquid to be ultrafiltered, so that it enters the shell body 1 and contacts the external pressure ultrafiltration membrane body 2 for filtration. Through the tight connection and coordinated work of the above components, this ultrafiltration membrane shell achieves efficient ultrafiltration and convenient cleaning functions.

[0031] When the equipment needs cleaning and maintenance, the operating procedure is as follows: First, start the motor 34. After the motor 34 starts working, it drives the transmission shaft 31 to rotate at high speed. The transmission shaft 31 drives the two transmission gears 32 connected to it to rotate synchronously. Due to the meshing transmission principle between gears, the two transmission gears 32 drive the two transmission gears 17 that mesh with them to rotate. When the two transmission gears 17 start to rotate, they play a transmission role. One transmission gear 17 drives the transmission gear 22 to rotate, and the other transmission gear 17 drives the transmission gear 24 to rotate synchronously. The rotation of the transmission gears 22 and 24 ultimately drives the external pressure ultrafiltration membrane body 2 to start rotating. The rotation of the external pressure ultrafiltration membrane body 2 provides a dynamic basis for the subsequent cleaning work.

[0032] After the motor 34 is started to rotate the external pressure ultrafiltration membrane body 2, the input end of the pump body 45 is placed in the cleaning solution, and then the pump body 45 is started. When the pump body 45 starts to operate, it generates suction, which continuously draws in the cleaning solution and guides it into the distribution plate 40 through the pipeline. The distribution plate 40 evenly distributes the cleaning solution into several delivery pipes 41. Finally, the cleaning solution is sprayed out at high speed from the nozzle 42 at the end of the delivery pipe 41, forming a fine water flow, which continuously rinses the membrane surface of the external pressure ultrafiltration membrane body 2.

[0033] During the continuous rotation of the external pressure ultrafiltration membrane body 2, the centrifugal force generated by the rotation of several membrane tubes, combined with the rinsing of the cleaning solution and the centrifugal force, allows the dirt adhering to the surface of the membrane tubes to be more easily removed. It should be noted that during the rinsing process, the sealing cover 13 should be opened so that the cleaned dirt can be smoothly discharged from the equipment, avoiding the accumulation of dirt inside the equipment, which would affect the cleaning effect and the normal operation of the equipment. Through this cleaning method, the dirt on the membrane tubes of the external pressure ultrafiltration membrane body 2 can be efficiently removed, ensuring its filtration performance and working efficiency.

[0034] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
