Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment tanks, and in particular relates to a detachable filtering structure of a sewage treatment tank. Background Art

[0002] When sewage is purified, it will be purified through a sewage treatment pool. The sewage flows into the adjustment area in the sewage treatment pool through the water inlet. The water quality and water quantity of the sewage are adjusted in the adjustment area. A filter is generally installed in the adjustment area to perform preliminary filtration of the sewage. The filter intercepts and filters larger impurities.

[0003] In Chinese patent application No. 201921335097.6, a replaceable filter screen for use in a wastewater filtration tank is disclosed, which introduces that the filter screen is installed in an adjustment area to perform preliminary filtration on the sewage entering the sewage treatment tank, thereby filtering out large particles of impurities in the sewage. After impurities are attached to the surface of the installed filter screen, the filter screen can be removed and taken out to clean the impurities attached to the filter screen. However, during the above cleaning process, the filter screen needs to be removed from the adjustment area, which will increase the operation time. In addition, when the filter screen is taken out to clean the impurities, the sewage impurities on one side of the filter screen in the adjustment area will enter the sewage on the other side, so that the sewage after the impurities are filtered out will be mixed with the sewage without filtering the impurities, thereby reducing the filtering effect of the filter screen on impurities in the sewage. For this reason, we propose a detachable filtering structure for a sewage treatment tank. Utility Model Content

[0028] The working principle and use process of this utility model:

[0029] When the utility model is in use, when there are a lot of impurities attached to the surface of the filter screen 103 in the sewage pool, the reduction motor 307 is started, and then the working end of the reduction motor 307 rotates to drive the spiral rod 300 to rotate. At this time, the nut seat 302 outside the spiral rod 300 moves upward, driving the long brush 305 to move, and then the long brush 305 can clean the impurities on the surface of the filter screen 103. During the rotation of the spiral rod 300, the rolling ball 309 is driven to rotate in the rolling hole 308 in the bottom plate 303. During the movement, the long brush 305 drives the L-shaped plate 304 to slide in the limiting groove in the limiting plate 301. When the long brush 305 moves upward to a suitable height position, the reduction motor 307 is reversed, driving the spiral rod 300 to reverse, and the nut seat 302 moves downward to drive the long brush 305 to move. At this time, the long brush 305 cleans the impurities on the surface of the filter screen 103 again, and the filter screen 103 can be cleaned without disassembling the filter screen 103 during the cleaning process;

[0030] During the process of cleaning impurities attached to the surface of the filter 103, the shield 200 serves to block and protect the reduction motor 307, thereby reducing the probability of water splashing onto the reduction motor 307 during the cleaning process. The shield 200 can be removed by unscrewing the screws on the fixing plate 201 on the shield 200, and the shield 200 can be installed by following the reverse principle mentioned above.
