Problems solved by technology

[0003] At present, there are certain problems in the process of using sewage treatment equipment to treat sewage. Nowadays, for the filtration of impurities in sludge, filter screens are required for filtration treatment. The filter screens used gradually accumulate during the filtration, resulting in filter screen damage. The filtration effect is poor, and the service life is short, which affects the filtration treatment of impurities. When the sewage is aerated, the aeration tube is required for aeration treatment. During the long-term use of the aeration tube for aeration, the flocculation in the water The dust may adhere to the surface of the aeration pipe, which will affect the effect of aeration, and it is very inconvenient to clean the aeration pipe. At the same time, the airtightness of the aeration pipe may be poor during the installation and disassembly process, which may easily generate sewage Leakage, in the final filtration of sewage treatment, the pump body cannot be used to change the flow rate of sewage filtration, so that the treatment efficiency when there is too much sewage cannot be solved, so that a large amount of sewage accumulates in the treatment equipment, resulting in equipment failure damage, for which we propose a small-scale domestic sewage treatment equipment based on

Embodiment 1

[0027] see Figure 1-5, a small-scale domestic sewage treatment equipment, including a first box 1, a second box 6 and a third box 14, the side wall of the first box 1 is fixedly connected with a sewage input pipe 2, the first box The top of 1 is fixedly installed with the first pump body 5, and the output end of the first pump body 5 is connected to the side wall of the second box body 6 through pipelines, and the second box body 6 is rotatably connected with two rotating wheels 7, and the two rotating wheels 7 The side wall is equipped with a transmission belt 8, and the transmission belt 8 is set at a forty-five angle with the horizontal plane, the outer wall of the transmission belt 8 is fixedly connected with a fixed frame 9, and the front and rear ends of the fixed frame 9 are provided with the first filter screen 11, and the fixed frame 9 The right side is provided with a second filter screen 12, the bottom end of the second box body 6 is fixedly connected with a partit...

Embodiment 2

[0030] see Figure 1-5 On the basis of Example 1, a further improvement is made: the bottom end of the first box 1 is provided with a sedimentation layer 3, the top of the sedimentation layer 3 is provided with a sewage layer 4, and the input pipeline of the first pump body 5 is connected to the second The inside of a box body 1, and the pipeline is located in the sewage layer 4; the upper side of one end of the fixed frame 9 is fixedly connected with the connecting rod 10, and the upper side of the first filter screen 11 is fixedly connected with the lower end of the connecting rod 10.

[0031] In this embodiment, by using the first tank 1 to divide the sewage into the sediment layer 3 and the sewage layer 4, the first pump body 5 can be used to extract the water in the sewage layer 3, and the connecting rod 10 can be used to ensure the first filtration. The installation strength of the net 11.

Embodiment 3

[0033] see Figure 1-5 , on the basis of Embodiment 1, a further improvement has been made: the first support spring 20 is fixedly installed on both sides of the top of the aeration pipe 18, and the top of the first support spring 20 is supported on the bottom end of the connecting plate 16; the second box 6. An installation pipe is fixedly installed on one side of the bottom end, and the installation pipe is connected to the side wall of the first box body 1; the partition plate 13 is located at one-third of the horizontal distance between the two rotating wheels 7; the top of the third box body 14 is fixedly connected to There is an installation pipe, and a medicine injector 30 is fixedly installed on the side wall of the installation pipe.

[0034] In this embodiment, the first support spring 20 can be used to support the aeration pipe 18 to ensure that the aeration pipe 18 shakes after installation, and the sludge and sundries can be transported to the first box 1 through ...

Abstract

The invention relates to the technical field of domestic sewage treatment, and discloses small-scale domestic sewage treatment equipment. The equipment comprises a first box body, a second box body and a third box body, wherein the side wall of the first box body is fixedly connected with a sewage input pipe; a first pump body is fixedly mounted at the top end of the first box body; the output endof the first pump body is connected to the side wall of the second box body through a pipeline; and two rotating wheels are rotatably arranged in and connected with the second box body, a transmission belt is installed on the side walls of the two rotating wheels, an angle of 45 degrees is formed between the transmission belt and a horizontal plane, a fixed frame is fixedly connected to the outerwall of the transmission belt, and first filter screens are arranged at the front end and the rear end of the fixed frame. According to the small-scale domestic sewage treatment equipment, impuritiesand sludge can be well filtered, the situation that the filtering effect of the filter screens is poor due to gradual accumulation of filtered impurities is avoided, the using period of a filtering device is guaranteed to be long, and the size of a sewage filtering flow can be changed through the pump body.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a small-scale domestic sewage treatment equipment. Background technique [0002] With the rapid development of my country's social economy, the construction of new countryside and the continuous advancement of urbanization, the urban population continues to concentrate, and the excrement and miscellaneous drainage that must be discharged in daily life are the main reasons for the pollution of urban rivers and small river ditches. . At present, large-scale industrial plants and urban sewage treatment plants will treat sewage, but most, especially small towns, rural areas, urban villages, fishing villages, etc. that do not have sewers and sewage treatment facilities, seldom process sewage, resulting in sanitary conditions. The situation continued to deteriorate. In order to prevent the water body from being further polluted, some small sewage treatment stations u...
