DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figures 1 to 8As shown, an MBR membrane integrated sewage treatment device includes a bracket 1, a reaction tank 2, a water production pipe 3, an installation component 6, an MBR membrane group 5 and a cleaning component 4, the cleaning component 4 includes a back pressure pump 41, a rotor group 42, a transport rope and a shovel 44, the bracket 1 is installed on both sides of the reaction tank 2, the water production pipe 3 is installed above the reaction tank 2 and connected to the ground, the installation component 6 is arranged on the bracket 1, the cleaning component 4 is installed at the bottom of the reaction tank 2, the back pressure pump 41 is installed on the ground and connected to the water production pipe 3, the rotor group 42 is installed on the pool wall of the reaction tank 2, the transport rope is arranged on the rotor group 42, and the shovel 44 is arranged at the bottom of the reaction tank 2 and connected to the transport rope.

[0028] The sewage treatment device sinks the MBR membrane group 5 into the sewage of the reaction tank 2 through the installation component 6, and the MBR membrane group 5 purifies the sewage and sends it to the water production pipe 3. Finally, the cleaning component 4 cleans and maintains the MBR membrane group 5 and the reaction tank 2. The function of the back pressure pump 41 is to reversely pressurize the water production pipe 3, so as to reversely clean the MBR membrane group 5. The shovel 44 is used to shovel the sludge settled at the bottom of the reaction tank 2 out of the reaction tank 2. The wheel group 42 and the transport rope provide the power source and movement direction for the shovel 44.

[0029] See also Figure 1-2 As shown, the back pressure pump 41 includes a first water valve 411, a second water valve 412 and a dosing box 413. The dosing box 413 is installed on the top of the back pressure pump 41. The first water valve 411 is installed on the side of the water production pipe 3 close to the back pressure pump 41, and the second water valve 412 is installed on the side of the water production pipe 3 away from the back pressure pump 41.

[0030] The dosing box 413 provides an inlet for the medicine required for cleaning the MBR membrane group 5. The first water valve 411 is used to control the connection between the back pressure pump 41 and the water production pipe 3. The second water valve 412 controls whether the water production pipe 3 can discharge clean water. When the MBR membrane group 5 is working, the first water valve 411 is closed and the second water valve 412 is opened to make the water pressure in the reaction tank 2 higher than that in the water production pipe 3, so that the clean water can flow out of the water production pipe 3. When cleaning the MBR membrane group 5, the first water valve 411 is opened, the second water valve 412 is closed, and the back pressure pump 41 presses the medicine into the MBR membrane group 5.

[0031] See also Figure 1 to Figure 3 As shown, the rotating wheel group 42 includes a first rotating wheel 421, a second rotating wheel 422, a positioning frame 423 and a rope puller 424. The first rotating wheel 421 is arranged on the pool wall at the bottom of the reaction pool 2, the positioning frame 423 is installed on the pool wall at the top of the reaction pool 2, the second rotating wheel 422 is installed on the positioning frame 423, and the rope puller 424 is placed on the ground and is outside the reaction pool 2.

[0032] The positioning frame 423 is used to embed and install the second rotating wheel 422 on the wall of the reaction tank 2, and the rope pullers 424 on both sides of the reaction tank 2 interact with each other to pull the transport rope 43, thereby pushing the shovel 44 to shovel the sludge at the bottom of the reaction tank 2, and finally pulling the shovel 44 out of the reaction tank 2 to centrally process the sludge.

[0033] See also Figure 3 to Figure 5 As shown, the mud shovel 44 includes a fixing ring 441 and a decompression groove 442 . The fixing ring 441 is arranged on both sides of the mud shovel 44 and is fixedly connected to the mud shovel 44 , and the decompression groove 442 is arranged on the mud shovel 44 .

[0034] The size of the fixing ring 441 is the same as that of the transport rope 43, which prevents the shovel 44 from getting stuck when passing through the rotating wheel group 42. The cavity of the shovel 44 is subject to water resistance at the bottom of the reaction tank 2, which makes it difficult for the shovel 44 to move forward. The decompression groove 442 is used to reduce the resistance encountered by the shovel 44.

[0035] See also Figure 1 to Figure 6 As shown, the MBR membrane group 5 includes an aeration pipe 51, a delivery pipe 52, a biofilm 53, a connecting pipe 54, a top cover 55, a bottom cover 56 and a pulley 57. One end of the aeration pipe 51 is installed on the side wall of the reaction tank 2, and the other end is installed on the bracket 1. The bottom cover 56 is installed on the mounting assembly 6. The delivery pipe 52 is installed on the bottom cover 56. The biofilm 53 is surrounded by the outside of the delivery pipe 52. The top cover 55 covers the top of the delivery pipe 52. One end of the connecting pipe 54 is connected to the top cover 55, and the other end is connected to the water production pipe 3. The pulley 57 is installed below the bottom cover 56.

[0036] The aeration pipe 51 provides a large amount of oxygen for the biofilm 53 to speed up the purification process. The bottom cover 56 and the top cover 55 combine the single delivery pipes 52 into groups to improve purification. When the MBR membrane group 5 is working, a negative pressure difference is formed between the water production pipe 3 and the delivery pipe 52. The sewage flows into the delivery pipe 52 and contacts with the biofilm 53. The biofilm 53 purifies the impurities in the sewage and sends the clean water into the delivery pipe 52. The clean water is then sent into the water production pipe 3 through the connecting pipe 54 after being gathered by the top cover 55. The connecting pipe 54 can be quickly removed from the top cover 55 and the water production pipe 3 to facilitate the installation of the MBR membrane group 5. The pulley 57 is used to quickly remove the delivery pipes 52 in rows from the MBR membrane group 5.

[0037] See also Figure 4 As shown, the aeration pipe 51 includes a fan 511 , a pressurizing pipe 512 and an air nozzle 513 . The fan 511 is installed on the bracket 1 , the pressurizing pipe 512 is installed on the side wall of the reaction tank 2 , and the air nozzle 513 is arranged on the pressurizing pipe 512 .

[0038] The fan 511 presses a large amount of external gas into the pressure pipe 512 and then sprays it out from the air nozzle 513, so as to increase the oxygen content in the sewage. The MBR membrane in the MBR membrane group 5 is extremely active in a high-oxygen environment and can effectively increase the sewage purification speed.

[0039] See also Figures 1 to 8 As shown, the mounting assembly 6 includes a slider 61 and a frame 62 . The slider 61 is mounted on the top of the bracket 1 , and the frame 62 is arranged directly below the slider 61 and connected to the slider 61 .

[0040] The frame 62 is used to fix the entire MBR membrane group 5 , and the slider 61 is used to control the displacement of the frame 62 so as to control the installation and removal of the MBR membrane group 5 .

[0041] See also Figure 8 As shown, the slider 61 includes a rotating shaft 611 and a steel wire 612 . The rotating shaft 611 is installed on the top of the slider 61 , and the steel wire 612 passes through the slider 61 and is connected to the frame 62 .

[0042] The rotating shaft 611 rotates to pull up and lower the steel wire 612 to control the rise and fall of the frame 62. When installing the MBR membrane group 5, a person stands on the bracket 1 to assemble the frame 62, and then the slider 61 slides and the rotating shaft 611 rotates to sink the MBR membrane group 5 into the reaction tank 2. When maintaining or replacing components, the frame 62 is first pulled up by the rotating shaft 611, and then the slider 61 drags the frame 62 to the side of the bracket 1, and the MBR membrane group 5 is manually maintained.

[0043] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
