Description

Technical Field

[0001] The present utility model relates to the field of sewage treatment, and specifically relates to a sewage treatment device. Background Art

[0002] Sewage treatment is an important part of environmental protection and sustainable development. With the rapid development of industrialization and urbanization, the sewage discharge volume is continuously increasing. If it is directly discharged into the environment without treatment, it will cause serious pollution to water bodies, soil and air, and thus affect human health and ecological balance.

[0003] Currently, when a large amount of sewage is treated, the sewage is usually filtered first. However, there are often problems such as unsatisfactory filtering effect, easy blockage of equipment, and high maintenance costs. After the current filtering device operates for a long time, a large amount of dirt is likely to accumulate on the filtering medium, resulting in a decrease in filtering efficiency and even complete blockage. In addition, cleaning and maintaining these devices are usually time-consuming and laborious, and increase the operating costs. Content of the Utility Model

[0004] In order to overcome the above deficiencies, the present utility model provides a sewage treatment device.

[0005] The technical solution adopted by the present utility model is as follows:

[0006] A sewage treatment device includes a bracket. A filter box is fixedly connected to the top of the bracket. The main body of the filter box is a cubic shell, and the bottom of the filter box is a funnel shape that tapers downward. A water outlet pipe is fixedly connected to the lower part of the bottom of the filter box, and a valve is installed on the water outlet pipe. There are two filter plates in the filter box, which are distributed vertically. The filter plates are fixedly connected to the inner wall of the filter box. Two cylinders are fixedly connected to the left side wall of the filter box, and the two cylinders are respectively located at the top of the two filter plates. The piston rod of each cylinder penetrates through the left side wall of the filter box, and the piston rod of each cylinder is slidably matched with the side wall of the filter box. The end of the output shaft of each cylinder is fixedly connected with a cleaning brush, and the two cleaning brushes are respectively located at the top of the two filter plates, and the cleaning brushes are in contact with the top of the filter plates. A collection box one and a collection box two are fixedly connected to the outer right wall of the filter box. The cross-sections of the collection box one and the collection box two are both L-shaped. The collection box two is located outside the bottom of the collection box one. Both the collection box one and the collection box two are communicated with the inside of the filter box. The communication parts between the collection box one and the collection box two and the filter box are respectively located at the top of the two filter plates. The bottom of the collection box one and the bottom of the collection box two are respectively flush with the upper surfaces of the upper and lower filter plates. There are two sewage pumps on the right side of the bracket. The input ends of the two sewage pumps are fixedly connected with extraction pipes, and the two extraction pipes respectively extend to the inner bottoms of the collection box one and the collection box two.

[0007] Sealing gaskets are inlaid at the connection parts between the collection box one and the collection box two and the filter box, and oil seals are fixed at the penetration parts of the output shafts of the cylinders and the filter box.

[0008] Advantages of the utility model:

[0009] The utility model adopts a two-layer filter plate design, which can effectively remove most of the suspended matters and solid particles in the sewage, improve the water quality of the effluent, automatically clean the dirt on the filter plate by a cylinder-driven cleaning brush, reduce manual intervention, improve the work efficiency and the automation degree of the equipment. The design of the first collection box and the second collection box enables the dirt to be effectively separated and collected.

[0016] As Figures 1-5As shown in the figure: A sewage treatment device includes a bracket 1. At the top of the bracket 1, a filter box 2 is fixedly connected. The main body of the filter box 2 is a cubic shell, and the bottom of the filter box 2 is a funnel shape that tapers downward. At the lower part of the bottom of the filter box 2, a water outlet pipe 3 is fixedly connected in communication. A valve is installed on the water outlet pipe 3. Inside the filter box 2, there are two filter plates 4, which are distributed vertically. The filter plates 4 are fixedly connected to the inner wall of the filter box 2. On the left side wall of the filter box 2, two cylinders 5 are fixedly connected. The two cylinders 5 are respectively located at the tops of the two filter plates 4. The piston rod of each cylinder 5 penetrates through the left side wall of the filter box 2, and the piston rod of each cylinder 5 is slidably matched with the side wall of the filter box 2. At the end of the output shaft of each cylinder 5, a cleaning brush 6 is fixedly connected. The two cleaning brushes 6 are respectively located at the tops of the two filter plates 4, and the cleaning brush 6 is in contact with the top of the filter plate 4. On the right outer wall of the filter box 2, a first collection box 7 and a second collection box 8 are fixedly connected. The cross-sections of the first collection box 7 and the second collection box 8 are both L-shaped. The second collection box 8 is located outside the bottom of the first collection box 7. Both the first collection box 7 and the second collection box 8 are in communication with the inside of the filter box 2. The communication points between the first collection box 7 and the second collection box 8 and the filter box 2 are respectively located at the tops of the two filter plates 4. The bottoms of the first collection box 7 and the second collection box 8 are flush with the upper surfaces of the upper and lower filter plates 4 respectively. On the right side of the bracket 1, there are two sewage pumps 9. The input ends of the two sewage pumps 9 are fixedly connected in communication with extraction pipes 10. The two extraction pipes 10 respectively extend to the inner bottoms of the first collection box 7 and the second collection box 8.

[0017] Sealing gaskets are inlaid at the connection points between the first collection box 7 and the second collection box 8 and the filter box 2, and oil seals are fixed at the penetration points of the output shafts of the cylinders 5 and the filter box 2.

[0018] First of all, the sewage is introduced into the filter box 2. Since there are two filter plates 4 distributed vertically in the filter box 2, the sewage will pass through these two filter plates 4 in sequence for primary and further filtration treatment.

[0019] Inside the filter box 2, impurities and particulate matters in the sewage will be intercepted by the filter plates 4, while the relatively clean water will continue to flow downward. This process helps to remove most of the suspended matters and solid particles in the sewage.

[0020] In order to maintain the filtration efficiency of the filter plates 4, the two cylinders 5 will respectively drive the two cleaning brushes 6 to move left and right on the tops of the two filter plates 4. The bottom of the cleaning brush 6 is in close contact with the top of the filter plate 4, and the dirt accumulated on the filter plate 4 is swept off through sliding friction. These swept-off dirt will respectively fall into the first collection box 7 and the second collection box 8.

[0021] The design of the first collection box 7 and the second collection box 8 enables the effective collection of dirt, preventing it from entering the filtration system again. At the same time, the two sewage pumps 9 are respectively connected to the inner bottoms of the first collection box 7 and the second collection box 8 through their respective extraction pipes 10, and the collected dirt can be pumped out for discharge.

[0022] After two - layer filtration, the relatively clean water will be discharged from the bottom of the filtration tank 2 through the water outlet pipe 3. At this time, just open the valve on the water outlet pipe 3 to achieve smooth discharge of the clean water. The present utility model only protects the mechanical part, and the functions realized through the software - controlled part related thereto are not within the protection scope of the present utility model.
