Description

A sewage treatment device

Technical Field

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

Background Art

With the continuous acceleration of urban development and the continuous improvement of people's living standards, more and more waste is produced by humans. Among them, municipal sludge, which has the most direct impact on humans and is the most difficult to dispose of, has become the focus of attention of environmental scholars. Municipal sludge is a by-product of the sewage treatment process in urban sewage treatment plants. It contains scum and flocs and sediments coagulated in different ways. The composition of sludge is related to the treatment process of urban sewage treatment plants and the properties of sewage. It is a relatively stubborn waste.

When applying for the present invention, the applicant found through searching that a Chinese patent disclosed a "municipal sewage treatment device" with the application number "202121850390.3". This patent mainly uses a sewage treatment mechanism to effectively clean sewage, thereby achieving efficient cleaning of sewage and avoiding the blockage of the inlet and outlet of the treatment box due to the presence of larger particles and garbage in the sewage, thereby effectively reducing the workload of the staff. At the same time, the larger particles and garbage are processed by the reciprocating push block, thereby improving the treatment efficiency of the sewage treatment mechanism, and effectively solving the problem of easy blockage inside the treatment box through the sewage treatment mechanism, while reducing the investment of manpower and material resources. However, the device directly pushes impurities in the sewage out of the device, which will cause the entire outlet surface of the device to be soiled by sewage, which will greatly increase the cleaning work of the operator on the device and increase the workload of the operator.

Utility Model Content

To achieve the above-mentioned purpose, a sewage treatment device is provided, comprising a device shell, a feed port is fixedly connected to the top of the device shell, a protective door is rotatably connected to the front of the device shell, a first connecting plate is fixedly connected to the lower surface of the device shell, a first roller is rotatably connected to the inner wall of the first connecting plate, a sewage tank is fixedly connected to the inner wall of the device shell, a cleaning plate is fixedly connected to the inner wall of the device shell, a cleaning mechanism is arranged above the cleaning plate, a discharge pipe is fixedly connected to the left side of the sewage tank and near the bottom edge, a sealing cover is movably connected to the end of the discharge pipe away from the sewage tank, a sieve plate is fixedly connected to the inner wall of the sewage tank, and a filter is fixedly installed on the inner wall of the sewage tank and below the sieve plate. The cleaning mechanism prevents solid matter in the sewage from clogging the holes on the sieve plate. The rate at which sewage passes through the sieve plate is accelerated, thereby improving the speed of sewage treatment. At the same time, it has the effect of refining some solid matter, increasing the number of solid matter passing through the sieve plate, thereby reducing the number of cleaning times for the sieve plate and the workload of operators. Larger solid matter is blocked on the sieve plate, reducing the probability of filter damage and extending the service life of the filter.

According to the sewage treatment device, the cleaning mechanism includes a track, the track is fixedly connected to the upper surface of the cleaning plate, and the lower surface of the inner wall of the track is meshed with a gear. The track and the gear cooperate with each other, so that the moving block and the soft bristles can move longitudinally to increase the cleaning area.

According to the sewage treatment device, a hydraulic rod is fixedly connected to the side of the gear close to the sewage tank, and a moving block is rotatably connected to the end of the hydraulic rod away from the gear. The hydraulic rod enables the moving block and the soft bristles to move laterally to increase the cleaning area.

According to the sewage treatment device, the lower surface of the moving block is fixedly connected with soft bristles, and the side of the gear away from the sewage tank is fixedly connected with a motor. The moving block cooperates with the inner wall of the sewage tank to crush some of the larger materials that should have stayed on the sieve plate, so that they pass through the sieve plate and fall into the filter net for centralized cleaning, thereby reducing the frequency of the operator's cleaning of the sieve plate and reducing the operator's workload.

According to the sewage treatment device, a square plate is fixedly connected to the lower surface of the motor, and a slide bar is fixedly connected to the lower surface of the square plate. The slide bar slides inside the cleaning plate and limits the relative movement up and down, thereby increasing the stability of the structure.

According to the sewage treatment device, the slide bar is slidably connected to the inner wall of the cleaning plate, and the lower surface of the slide bar is fixedly connected to a second connecting plate. The second connecting plate provides support for the second roller, thereby increasing the stability of the device.

According to the sewage treatment device, the inner wall of the second connecting plate is rotatably connected to a second roller, and the second roller is movably connected to the inner wall of the cleaning plate. The second roller avoids sliding friction between the slide rod and the cleaning plate, reduces wear between components, and prolongs the service life of the device.

The beneficial effects of the utility model are as follows: the cleaning mechanism is used to prevent solid matter in the sewage from clogging the holes on the sieve plate, and the rate at which sewage passes through the sieve plate is accelerated by pushing, thereby improving the speed of sewage treatment, and at the same time has the effect of refining some solid matter, increasing the amount of solid matter passing through the sieve plate, thereby reducing the number of cleaning times for the sieve plate and reducing the workload of operators. Larger solid matter is blocked on the sieve plate, reducing the probability of filter damage and extending the service life of the filter.
