Abstract

The utility model relates to the technical field of sewage treatment, and discloses an integrated sewage treatment device, including a sewage treatment box, wherein a filtering mechanism and a cleaning mechanism are arranged inside the sewage treatment box, wherein the cleaning mechanism is located below the filtering mechanism; the filtering mechanism includes a filter screen fixedly mounted on the inner wall of the sewage treatment box. The utility model arranges a cleaning mechanism below the filtering mechanism, and when the threaded rod in the cleaning mechanism rotates, it drives the cross bar to move, and when the cross bar moves, the sleeve rotates on the cross bar with the cooperation of the rack and the gear ring, and when the sleeve rotates, it drives the flapping plate to rotate. Since a plurality of convex angles with the filter screen are arranged on the outer side of the flapping plate, when the flapping plate rotates, the convex angles will repeatedly flap the filter screen, causing the sludge adhered to the filter screen to fall out, thereby preventing the sludge from accumulating and clogging the filter screen, and affecting the sludge filtering effect.

Description

An integrated sewage treatment device

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to an integrated sewage treatment device.

Background Art

Wastewater treatment refers to the treatment of water containing pollutants such as domestic sewage, industrial wastewater and farmland drainage to make it harmless to the environment and human health. The usual sewage treatment process includes pretreatment, primary treatment, intermediate treatment and advanced treatment. Pretreatment includes solid removal and sedimentation, and primary treatment mainly removes solids and large particle pollutants in water through physical methods such as sedimentation, screening and suspended matter removal.

The utility model with announcement number CN219186071U discloses an integrated sewage treatment device with sludge treatment, including a sewage treatment box, the inner wall of the sewage treatment box is symmetrically fixedly connected with a U-shaped mounting bar, the inside of the symmetrically arranged U-shaped mounting bar is slidably connected with a filtering mechanism, the interior of the sewage treatment box is provided with a cleaning mechanism, the top of the cleaning mechanism is abutted with the lower surface of the filtering mechanism, the interior of the sewage treatment box is provided with an adjusting mechanism, the outer wall of the adjusting mechanism is threadedly connected with a scraper, the lower surface of the scraper is abutted with the bottom of the inner wall of the sewage treatment box, the upper surface of the scraper is fixedly connected with an L-shaped protective cover, and one side of the sewage treatment box is fixedly connected with a bucket-shaped sewage outlet that penetrates the sewage treatment box. It uses a scraper to push the sludge accumulated at the bottom of the sewage treatment tank out of the tank to minimize the frequency of the filter mechanism being blocked again. However, its cleaning mechanism uses a plate brush to clean the filter plate, but the plate brush can only brush the sludge adhered to the bottom of the filter plate. It has poor cleaning power for the sludge adhered to the mesh of the filter plate. Long-term use will cause the filter plate to be blocked, affecting the sludge filtration efficiency.

Therefore, we proposed an integrated sewage treatment device to solve the above problems.

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

Please refer to Figures 1-6, the utility model provides an integrated sewage treatment device, including a sewage treatment tank 1 with a water inlet pipe 11 and a water outlet pipe 12 on one side, a filtering mechanism 2 and a cleaning mechanism 3 are arranged inside the sewage treatment tank 1, the cleaning mechanism 3 is located below the filtering mechanism 2 and parallel to the filtering mechanism 2, the water inlet pipe 11 is located above the filtering mechanism 2, and the water outlet pipe 12 is located below the filtering mechanism 2;

The filtering mechanism 2 includes a filter screen fixedly mounted on the inner walls of the left and right sides of the sewage treatment tank 1;

The cleaning mechanism 3 includes a threaded rod 31 rotatably mounted on the inner walls of the left and right sides of the sewage treatment tank 1 and a driving motor 36 fixed on the outside of the sewage treatment tank 1. One end of the threaded rod 31 passes through the outer wall of the sewage treatment tank 1 and is fixed to the rotating shaft of the driving motor 36. The threaded rod 31 is threadedly connected with a ring 32, and a cross bar 33 is fixed on the ring 32. The cross bar 33 is arranged along the front and rear direction of the sewage treatment tank 1, and a sleeve 34 is rotatably mounted on the outside of the cross bar 33. Specifically, a rack 37 parallel to the threaded rod 31 is arranged between the left and right inner walls of the sewage treatment tank 1, and a gear ring 38 meshing with the rack 37 is coaxially fixed on the sleeve 34. A plurality of flapping plates 35 with convex angles are fixed to the outer wall of the sleeve 34. The plurality of flapping plates 35 are equidistantly arranged along the axial direction of the sleeve 34, and the flapping plates 35 are in contact with the bottom of the filtering mechanism 2.

The sewage entering from the water inlet pipe 11 is filtered through the filter to separate the sludge from the water. After the driving motor 36 is started, it drives the threaded rod 31 to rotate. When the threaded rod 31 rotates, it drives the cross bar 33 to move along the left and right directions of the sewage treatment tank 1 through the ring 32. With the cooperation of the rack 37 and the gear ring 38, the sleeve 34 rotates on the cross bar 33, driving the flapping piece 35 to rotate. When the flapping piece 35 rotates, the convex corners on the outer side of the flapping piece 35 have a flapping effect on the filter, so that the sludge adhered to the mesh of the filter falls out, thereby improving the cleaning effect and preventing the filter from being blocked.

As a preferred technical solution of the utility model: a slip ring 30 is fixed to one end of the cross bar 33 away from the threaded rod 31, and a guide rod 39 parallel to the threaded rod 31 is slidably installed in the slip ring 30, and the two ends of the guide rod 39 are respectively fixed to the left and right inner walls of the sewage treatment tank 1, and the guide rod 39 cooperates with the slip ring 30 to guide the movement of the cross bar 33.
