Description

A filter device for urban sewage

technical field

The invention relates to a filter device for urban sewage treatment, belonging to the technical field of sewage treatment.

Background technique

At present, China's water resources are extremely scarce, and people's awareness of water saving still needs to be improved. It is difficult to achieve the goal by people's own water saving, and it is not feasible to increase the water price because of the people's economic level. It is necessary to improve domestic water waste. At present, the discharged wastewater shows a rapid growth trend, which not only causes a great waste of water resources, but also increases the workload of sewage treatment units. Among them, the treatment and filtration of sludge are not thorough enough, resulting in poor sewage filtration effect.

Industrial production and residents' daily life will produce a large amount of sewage. If these sewage are directly discharged into creeks and rivers without treatment, the water quality and environmental landscape will be seriously affected. Therefore, sewage needs to be collected into sewage pools. A series of procedures such as alum, chlorination, etc., are finally discharged into the river.

Urban sewage includes domestic sewage and industrial sewage. For the treatment of domestic sewage, the traditional method is to directly discharge domestic sewage into the environment, which will seriously pollute the environment, and some domestic sewage has a great odor, which makes the sewage with odor. After being directly discharged into the environment, it has brought great trouble to people's lives, affecting people's lives and the environment. For the treatment of domestic sewage, in addition, in the existing sewage treatment, the treatment device is easy to be polluted by the sewage. The residues and impurities contained will block the treatment equipment, which will affect the discharge of sewage, thereby reducing the effect of sewage treatment, which is not conducive to the timely discharge of sewage and affects people's lives.

The width of the filter layer is the same, and the size of the scraper is the same as the size of the sewage chamber. The scraper pushes out the sludge and other impurities on the filter layer and discharges it from the sewage discharge chamber, so that the filter layer will not accumulate sludge and improve the filtration efficiency. When the device is filtering water, the scraper moves into the sewage cavity to block the sewage cavity to prevent the water from flowing out of the sewage cavity and play a sealing role. A positioning hole is opened on the outer wall of the water inlet cavity, and a sealing ring is arranged in the positioning hole. The piston rod of the telescopic hydraulic pump is connected with the scraper through the sealing ring, and the sealing ring plays a sealing role to prevent water from flowing out.

Preferably, a drainage pipe that communicates with the outside is provided in the sewage cavity. The sludge is discharged from the sewage cavity and flows out from the drainage pipe to the outside world. When filtering is required, the scraper blocks the drainage tube or moves to the left side of the drainage tube to prevent water from flowing out of the drainage tube.

Further, the filter layer includes a support frame, a filter element, a sealing plate and a handle, a mounting hole is provided on one side of the inner wall of the water collection tank, the support frame is fixedly arranged in the water collection tank, and the position of the support frame is Corresponding to the position of the installation hole, the filter element is movably arranged in the support frame, the filter element is fixedly arranged on the sealing plate, a handle is fixedly arranged on the sealing plate, and the sealing plate is connected to the sealing plate. Mounting holes are fitted with seals. The filter element in the filter layer can be extracted for cleaning, which is convenient for subsequent use and improves the filtration efficiency.

Preferably, the support frame is formed by four guide pillars enclosed with the inner wall of the water collecting tank, and the four guiding pillars are fixedly arranged on the inner wall of the water collecting tank. The support frame structure is adopted, so that the area of water passing through the filter layer is larger, and the filtering efficiency is improved.

Beneficial effects: the present invention drives the turntable to rotate under the action of the motor, and the stirring rod stirs the sewage, so that the sludge dewatering efficiency in the sewage is improved, and the sewage treatment effect is better. Under the action of the hydraulic pump, the piston rod is driven to move, so that the scraper under the scraper scrapes the sludge on the filter layer, scrapes it out from the sewage chamber, and flows out along the drainage pipe, so that the filter device is not easy to be blocked, and the filtering effect is improved. The invented filter layer makes the filtering effect better and the quality of the sewage effluent better.
