Technical Field

[0001] The utility model relates to the technical field of MBR membrane assembly cleaning, in particular to a waste MBR membrane assembly cleaning device. Background Art

[0002] In the fields of wastewater treatment and water resource reuse, MBR, also known as membrane bioreactor, is a novel water treatment technology that combines activated sludge with membrane separation. There are many types of membranes. Based on the separation mechanism, they include reactive membranes, ion exchange membranes, and osmotic membranes. Based on their properties, they include natural membranes (biofilms) and synthetic membranes (organic and inorganic membranes). Based on their structural type, they include flat plate, tubular, spiral, and hollow fiber membranes.

[0003] Application number CN202120827096.4 discloses a cleaning device for efficiently cleaning MBR membrane modules, including a cleaning tank and other structures. This device provides excellent cleaning effects and high efficiency. However, when cleaning a membrane module covered with mud, the cleaning brush heads arranged in a single direction are difficult to quickly remove the mud, reducing cleaning efficiency. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A device for cleaning an abandoned MBR membrane assembly comprises a cleaning mechanism, wherein the cleaning mechanism comprises a cleaning box, a filter membrane group movably passing through the top of the cleaning box, a support rod transversely passing through the filter membrane group and affixed to the top of the cleaning box, a plate body connected to the top of the cleaning box, two rod sleeves slidably sleeved on the outer ends of the support rods, a spring installed inside the rod sleeves, a pad affixed between the rod sleeves and the springs, a motor connected to the top of the cleaning box, and a cam connected to the output shaft of the motor, wherein the cam is affixed to one side of the support rod, and the rod sleeves are fixed to the plate body.

[0007] By adopting the above technical solution, the filter membrane group is lifted by the support rod, and then the motor is started. Every time the cam rotates one circle, it will collide with one side of the support rod, and then the support rod is translated against the top of the cleaning box. Here, the pad slides under force and then squeezes the spring. The spring reciprocates and expands, which can make the support rod move at a high frequency, thereby shaking the filter membrane group, and then the mud blocks on the filter membrane group are quickly shaken off, effectively improving the cleaning efficiency of the filter membrane group.

[0008] In a preferred example, the present invention can be further configured as follows: a cleaning mechanism is provided on the cleaning box, and the cleaning mechanism includes a horizontal plate fitted with the outer wall of the cleaning box, a water tank installed on the outside of the horizontal plate, a plurality of water pipes passing through the horizontal plate, and a water source pipe connected to and communicated with the water tank, and the water pipe is communicated with the inside of the water tank.

[0009] In a preferred example, the present invention can be further configured as follows: a plurality of water pipes are arranged in a row at equal intervals, and the water pipes extend into the interior of the filter membrane group.

[0010] In a preferred example, the present invention can be further configured as follows: a sewage pipe is installed on the cleaning box, the sewage pipe is located at the bottom of the horizontal plate, and a plug cover is screwed onto the outer end.

[0011] In a preferred example, the present invention can be further configured as follows: a stabilizing sleeve is sleeved on the outer side of the support rod, and the cam movably extends into the interior of the stabilizing sleeve.

[0012] In a preferred example, the present invention can be further configured as follows: two guide rods are installed on the outer wall of the cleaning box, the two guide rods are vertically symmetrical with respect to the water tank, and are plugged into the horizontal plate.

[0013] In a preferred example, the present invention can be further configured as follows: an L-shaped glass is embedded in the cleaning box.

[0014] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0015] 1. In the utility model, the filter membrane group is lifted by the support rod, and then the motor is started. Every time the cam rotates one circle, it will collide with one side of the support rod, and then the support rod moves horizontally against the top of the cleaning box. Here, the pad slides under force, and then squeezes the spring. The spring reciprocates and expands, which can make the support rod move at a high frequency, thereby shaking the filter membrane group, and then the mud blocks on the filter membrane group are quickly shaken off, effectively improving the cleaning efficiency of the filter membrane group.

[0016] 2. In the present invention, when a large area of ​​mud blocks on the filter membrane group fall off, external water is injected into the water tank from the water source pipe, and then diverted from multiple water pipes to achieve cleaning of the inside of the filter membrane group and improve the cleaning effect of the filter membrane group.

[0031] Furthermore, a stabilizing sleeve 300 is sleeved on the outer side of the support rod 130 , and the cam 190 movably extends into the interior of the stabilizing sleeve 300 . The provision of the stabilizing sleeve 300 can ensure that the cam 190 stably collides with the support rod 130 .

[0032] Furthermore, an L-shaped glass is embedded in the cleaning box 110 , and the L-shaped glass is provided to facilitate the staff to check the cleaning progress of the filter membrane group 120 .

[0033] Example 2:

[0034] Combine Figure 1 and Figure 4 As shown, on the basis of embodiment 1, a cleaning mechanism 200 is provided on the cleaning box 110, and the cleaning mechanism 200 includes a horizontal plate 210 fitted with the outer wall of the cleaning box 110, a water tank 220 installed on the outside of the horizontal plate 210, a plurality of water pipes 230 running through the horizontal plate 210, and a water source pipe 240 connected to and communicated with the water tank 220. The water pipe 230 is communicated with the interior of the water tank 220. When a large area of ​​mud blocks on the filter membrane group 120 fall off, the external water source is injected into the water tank 220 from the water source pipe 240, and then diverted from the plurality of water pipes 230 to achieve cleaning of the interior of the filter membrane group 120 and improve the cleaning effect of the filter membrane group 120.

[0035] Furthermore, a plurality of water pipes 230 are arranged in a row at equal intervals, and the water pipes 230 extend into the interior of the filter membrane group 120 . With this layout design, the interior of the filter membrane group 120 can be cleaned evenly.
