Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment equipment, and in particular to a treatment equipment for recycling painting wastewater. Background Art

[0002] It should be noted that when treating sewage, the sewage is aerated through the aeration head, and then the sewage is filtered through the membrane bioreactor and flows out through the outlet pipe to complete the filtration of the coating sewage. In the treatment process of coating sewage, the components in the sewage are complex. Therefore, when filtering in the membrane bioreactor, it is easy to cause blockage of the membrane bioreactor, and the aeration head is directly soaked in water for a long time without any protective measures. Therefore, it is easy to cause accumulation of impurities, and then cause blockage. The membrane bioreactor treatment tank is generally large in size and is installed in multiple groups. Therefore, when it is blocked, the specific location of the blockage cannot be known in time; in addition, the treatment tank is full of pollutants, so during maintenance, it is easy to cause harm to the body of the staff. If it is vacant for a long time and then treated, it is easy to affect the continuous treatment of sewage, so it cannot meet the needs of sewage treatment. Summary of the invention

[0062] In summary, the working principle of a treatment device for recycling painting wastewater provided by an embodiment of the present invention is:

[0063] When the coating wastewater is treated in the treatment pool 1, the wastewater is filtered through the membrane bioreactor 3 and then output through the outlet pipe 4. At the same time, the fan conveys gas to the gas pipe rack 7 through the air inlet pipe 11, so that the multiple aeration heads 8 can be continuously aerated to ensure the treatment effect of the wastewater. It should be noted that when the membrane bioreactor 3 is blocked, the water output of the membrane bioreactor 3 is reduced. At this time, the water level in the adapter box 601 drops, and under the gravity of the counterweight block 604, the adapter rack 603 is driven downward by the alarm light 613, and then the upper floating plate 602 is driven downward. At the same time, the alarm light 613 drives the switch 614 to move downward, so that the switch 614 is squeezed by the adapter box 601 and is triggered, and then The alarm light 613 is turned on, so that the staff can accurately know which membrane bioreactor 3 is blocked, thereby improving the maintenance efficiency of the membrane bioreactor 3 and ensuring the continuous treatment of sewage; in addition, when the adapter frame 603 moves down, the transfer shaft 611 drives the rotating rod 606 to rotate, and the transfer shaft 611 slides in the transfer chute 610, so that the rotating rod 606 drives the two linkage rods 605 to approach each other through the two linkage shafts 609, and then the two linkage rods 605 drive the two flushing covers 501 to close the membrane bioreactor 3, and the rotating shaft 608 rotates in the rotating seat 607, so that the torsion spring 612 is stressed;

[0064] Furthermore, when the two flushing covers 501 are closed, the membrane bioreactor 3 can be effectively isolated from the external sewage. The flushing covers 501 slide horizontally in the moving groove 508 through the moving rod 509, so that the squeezing rods 507 on the two flushing covers 501 are squeezed and retracted. The movement of the squeezing rod 507 drives the blocking frame 504 to move, and the return spring 505 is forced to shrink. At this time, the water in the flushing pipe 503 is injected into the flushing cover 501 and sprayed out through multiple flushing heads 502 to actively clean the outside of the membrane bioreactor 3. During flushing, it is not affected by external sewage, and the flushing effect can be effectively guaranteed, thereby achieving the purpose of automatically cleaning the membrane bioreactor 3 when the membrane bioreactor 3 is closed, and effectively ensuring the treatment effect of coating sewage.

[0065] Furthermore, when the fan 10 blows air, the air inlet pipe 11 blows the air into the air inlet box 903, and the follower plate 906 is blown and then rotates. When the follower plate 906 rotates, it rotates on the connecting shaft 907, and the rebound torsion spring 908 is stressed. When the follower plate 906 rotates, it pushes the driving frame 904 to move, and the multiple return springs 905 are stressed. When the driving frame 904 moves, the lifting frame 901 drives the multiple sealing covers 902 to move, so that the multiple aeration heads 8 are exposed, so that Aeration is achieved; similarly, when the air intake is stopped, the follower plate 906 is closed under the rebound force of the rebound torsion spring 908, and the driving frame 904 is reset under the rebound force of multiple return springs 905, so that the multiple closing covers 902 close the aeration head 8, so as to avoid the aeration head 8 being exposed to accumulate impurities and cause blockage and damage; in addition, when the closing cover 902 moves down, the cleaning circle 909 moves synchronously to clean the outside of the aeration head 8, thereby further ensuring the normal use of the aeration head 8.
