Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a circulating wastewater treatment device. Background Art

[0002] A circulating wastewater treatment device is a device used to treat and purify wastewater. Its main purpose is to remove or reduce pollutants in the wastewater to a level that can be safely discharged or reused. This type of device usually uses physical, chemical and biological treatment methods to treat wastewater to remove suspended solids, organic matter, heavy metals, bacteria and other pollutants in the wastewater.

[0003] After searching, the Chinese patent document announcement number: CN213965375U discloses a wastewater circulation treatment device. When the wastewater flows to the filter through the square tube, the wastewater will flow to the filter through the sieve plate. At this time, the floating objects on the wastewater will remain on the sieve plate and flow to the collection box below the sieve plate with the sieve plate, thereby achieving the effect of filtering and collecting the floating objects in the wastewater. After the square tube has been used for a period of time, the cover plate above the square tube is opened, and then the handle is pulled to make the handle drive the sieve plate to slide along the inner wall of the track plate. At this time, the slider will slide along the track plate. When the sieve plate slides to the farthest end from the water pipe, the sieve plate is rotated. At this time, the sieve plate rotates with the help of the slider and the track plate, and then the card block is pressed to make the two card blocks move towards each other. At this time, the card block is disengaged from the slide groove of the baffle plate, and then the collection box is taken out, and the floating objects collected in the collection box are poured out, so as to facilitate the transfer of the floating objects in the collection box, and then the card blocks at both ends of the collection box are slid into the slide groove of the baffle plate. When the card block moves to the circular hole of the slide groove, the card block will extend from the circular hole under the elastic force of the first spring, thereby fixing the collection box on the baffle plate, and then the cover plate is put back on, so as to achieve the effect of repeated physical filtration of the floating objects in the wastewater.

At this time, the movable plate 23 applies an extruding force to the spring 22, and then the filter plate 14 is placed at a position that matches the collection box 13, and the pressing plate 17 is released. The clamping rod 21 is pushed to slide to the inside of the clamping groove 25 through the reaction force of the spring 22 to complete the clamping and fix the filter plate 14 inside the collection box 13. The detachable filter plate 14 can usually be thoroughly cleaned to eliminate any dirt or blockage, thereby improving the efficiency and performance of the filtering equipment. The filtered water is transported to the inside of the sedimentation barrel 2 through the water pump 15, and re-precipitated for further recycling, saving water resources.
