Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a cleaning device for membrane recovery in industrial wastewater treatment. Background Technique

[0002] The ultrafiltration device disclosed in the publication number CN214141833U for industrial wastewater treatment and recovery includes an ultrafiltration membrane module. The bottom and top of the ultrafiltration membrane module are respectively communicated with one end of a connecting pipe and a return water pipe facing the ultrafiltration membrane module. The right side of the ultrafiltration membrane module is communicated with the left end of a purified water pipe. In this ultrafiltration device, water flows through a jet injector and the ultrafiltration membrane module. Under the drive of pressure, substances with small sizes such as water, organic low-molecules, and inorganic ions in the sewage can pass through the micropores on the fiber wall to reach the other side of the membrane, while large-sized substances such as bacteria, colloids, particulate matters, and organic macromolecules in the solution are intercepted, so that the device has a good filtering effect on sewage. By setting a coarse filtration device, the coarse filtration device can pre-treat the sewage in advance to reduce the entry of larger particulate matters into the ultrafiltration membrane module. However, the following problems still exist in the actual use of this patent:

[0003] The cleaning methods of ultrafiltration membranes can be generally divided into two categories: physical cleaning methods and chemical cleaning methods. Reverse flushing is to flush the impurities inside the membrane and the inlet end face with raw water. The filtered impurities of ultrafiltration membranes are basically millimeter-sized particulate matters. Existing ultrafiltration membranes are basically installed by bolts. When the ultrafiltration membrane needs to be disassembled due to idleness, it is not convenient to operate, nor is it convenient for the regular replacement of the ultrafiltration membrane.

[0004] A cleaning device for membrane recovery in industrial wastewater treatment is proposed to solve the problems mentioned above. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A cleaning device for membrane recovery in industrial wastewater treatment includes a cleaning chamber. The cleaning chamber includes a chamber shell. The top of the chamber shell is threadedly connected with a water inlet cover, and the bottom of the chamber shell is provided with a water outlet;

[0007] Inside the bin housing, a placement component is provided. The placement component includes a placement frame inserted inside the bin housing. Inside the placement frame, a membrane body is fixedly installed, with the filtering surface of the membrane body facing outward. Outside the top of the placement frame, a carrying handle is fixed.

[0008] Among them, a cleaning mechanism is provided below the inside of the bin housing.

[0009] Preferably, on both sides inside the mechanical bin, sliding rails are symmetrically installed. Inside the mechanical bin, there is a lifting block slidably connected to the sliding rails. On the front of the lifting block, an annular groove is formed. The lifting block overlaps with the fixed clamping block.

[0010] Preferably, the annular groove is an annular groove with a special shape. Between the bottom of the mechanical bin and the inside of the lifting block, a number of return springs are fixedly connected. The elasticity of the return springs is relatively strong. A sliding column is slidably connected to the annular groove. The sliding column is rotatably connected to a rocker. The bottom end of the rocker is rotatably connected to the lower part inside the mechanical bin.

[0011] Preferably, on both sides of the lifting block, slope blocks are symmetrically fixed. On both sides of the top of the mechanical bin, rotary hook rods are symmetrically installed.

The top end of the rotary hook rod is snap-fitted with the fixed clamping block.

[0012] Preferably, the cleaning mechanism includes a reciprocating lead screw rotatably installed on one side inside the bin housing. A threaded sleeve is threadedly slidably sleeved on the reciprocating lead screw. The bottom end of the reciprocating lead screw is fixedly connected to a first gear.

[0014] Preferably, a transmission shaft is rotatably penetrated through the middle of the transmission bin. The other end of the transmission shaft is located below the reciprocating lead screw and is rotatably connected to the transmission bin.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: For a cleaning device for membrane recovery in industrial wastewater treatment, the placement frame and the membrane body can be quickly disassembled and assembled, facilitating the rapid replacement of the ultrafiltration membrane, avoiding the problems of increased disassembly and assembly time caused by the use of screws and bolts and possible thread slipping, thereby enabling the device to stably and quickly clean the ultrafiltration membrane to be recovered. The specific content is as follows:

[0016] 1. By pressing the placement frame, the fixed clamping block descends, causing the lifting block to descend and compress the return spring. Subsequently, the sliding column slides along the annular groove and engages with the other end of the annular groove. At the same time, as the ramp block presses the roller, the rotating hook rod rotates, and finally the top end of the rotating hook rod engages with the fixed clamping block. Through the fixed clamping block and the rotating hook rod, the placement frame can be stably and quickly installed, enabling the placement frame and the membrane body to be quickly disassembled and assembled, facilitating the rapid replacement of the ultrafiltration membrane, avoiding the problems of increased disassembly and assembly time caused by the use of screws and bolts and possible thread slipping, and thereby enabling the device to stably and quickly clean the ultrafiltration membrane to be recovered.

[0017] 2. Clean water enters from the water inlet cover, passes through the inside of the placement frame, flows into the impurity-free surface of the membrane body, and flows out from the impurity surface of the membrane body. As a result, the impurities on the impurity surface are washed away. The water flow passes through the spiral blade, causing the spiral blade to rotate. Then, through the drive shaft, the second gear rotates. Subsequently, through the transmission shaft and two transmission gears, the first gear drives the reciprocating lead screw to rotate. Thereby, through the threaded sleeve, the fixed ring moves up and down, ultimately promoting the circular brush to quickly brush away the impurities on the outside of the ultrafiltration membrane, accelerating the cleaning of the ultrafiltration membrane.

[0033] Working principle: Before using this cleaning device for membrane recovery in industrial wastewater treatment, it is necessary to first check the overall condition of the device to ensure that it can work normally. According to Figure 1 - Figure 5 As shown in the figure, first hold the carrying handle 203 and place the placement frame 201 into the inner part of the bin housing 101 from the water inlet cover 102. At this time, press down the placement frame 201 to make the fixed clamping block 204 descend, so that the lifting block 207 descends and compresses the return spring 209. Furthermore, the sliding column slides along the annular groove 208 and engages with the other end of the annular groove 208. At the same time, as the ramp block 211 presses the roller 213, the rotating hook rod 212 rotates. Finally, the top end of the rotating hook rod 212 engages with the fixed clamping block 204. Through the fixed clamping block 204 and the rotating hook rod 212, the placement frame 201 can be stably and quickly installed and fixed, so that the placement frame 201 and the membrane body 202 can be quickly disassembled and assembled, facilitating the rapid replacement of the ultrafiltration membrane, avoiding the problems of increased disassembly and assembly time caused by the use of screws and bolts and possible thread slipping problems, and further enabling the device to stably and quickly clean the ultrafiltration membrane that needs to be recovered.

[0034] When the device cleans the filter membrane, clean water enters from the water inlet cover 102, flows through the inside of the placement frame 201 and into the impurity-free surface of the membrane body 202, and flows out from the impurity outlet of the membrane body 202. Thus, the impurities on the impurities are washed. And the water flow passes through the spiral blade 308, causing the spiral blade 308 to rotate. Then, through the drive shaft 307, the second gear 309 rotates. Further, through the transmission shaft 310 and the two transmission gears 311, the first gear 303 drives the reciprocating lead screw 301 to rotate. Thus, through the thread sleeve 302, the fixed ring 312 moves up and down, and finally promotes the circular brush 313 to quickly brush away the impurities on the outside of the ultrafiltration membrane, accelerating the cleaning of the ultrafiltration membrane.

[0035] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
