Description

Bottom self-flushing integrated pump station

technical field

The utility model relates to the field of urban and rural sewage treatment equipment, in particular to a cylinder bottom self-flushing integrated pump station.

Background technique

With the development and progress of society, the requirements for environmental governance are getting higher and higher, and industrial and agricultural production and urban and rural sewage treatment are increasingly diversified. At present, my country's small and medium-sized sewage treatment pumping stations have a large volume and a wide range. During the sewage treatment process, the bottom of the pumping station tends to accumulate sediment in the sewage, which rots and stinks, affecting the normal operation of the pumping station. It requires a lot of manpower to deal with it, which is laborious and time-consuming. The concrete bottom of traditional pumping stations generally adopts a flat bottom structure, usually with serious sludge accumulation, and manual dredging is required periodically to ensure the normal use of the pump. This work is not only cumbersome, but also poses certain dangers to dredgers.

Contents of the invention

In view of the above existing problems, the technical problem to be solved by this utility model is to provide a self-flushing integrated pump station at the bottom of the cylinder that can automatically remove the sediment at the bottom of the pump station. ,low cost.

For achieving the above object, the technical scheme that the utility model adopts is:

A cylinder bottom self-flushing integrated pumping station, comprising: a cylinder body, a submersible sewage pump is arranged in the cylinder body, a submersible sewage pump lifting pressure pipe is connected to the outlet of the submersible sewage pump, and a submersible sewage pump is installed on the cylinder wall There is a water inlet pipe, and a basket grille is connected to the water inlet pipe. The basket grille includes a box body, a filter screen or a grid bar is arranged at the bottom of the box body, and a water connection pipe is connected to the bottom of the box body. The outlet of the water connection pipe faces bottom of the cylinder.

Compared with the prior art, the utility model has the following advantages:

The utility model utilizes the water receiving pipe connected to the lower end of the basket grille to draw part of the water to flush the bottom of the cylinder of the pump station, so that the sediment in the sewage that is easy to accumulate at the bottom of the cylinder is washed away in time, realizing the sedimentation at the bottom of the pump station Automatic removal of objects.

The technical measures at the bottom of the V-shaped cylinder usually concentrate the sediment in the sewage in the V-shaped low-lying part of the cylinder, and the technical measures at the top of the V-shaped bottom of the cylinder make the water flush to the V-shaped bottom of the cylinder. The upper part of the V-shaped bottom is then washed along the V-shaped bottom to the bottom of the V-shaped bottom where the dirt is deposited, so as to form a strong scouring of the sediment concentration area and take away the sediment.

When the submersible sewage pump stops running, a small amount of sewage will stay at the V-shaped bottom. When the pump is started again, the water pouring down from the water inlet will wash the bottom of the cylinder, and the high flow rate formed by the pump’s starting operation will strengthen the self-cleaning effect. The effect is to eliminate the peculiar smell inside the pump station and ensure the cleanliness inside the pump station.

detailed description

A cylinder bottom self-flushing integrated pumping station, comprising: a cylinder body 1, a submersible sewage pump 2 is arranged inside the cylinder body 1, a submersible sewage pump lifting pressure pipe 3 is connected to the outlet of the submersible sewage pump 2, and a submersible sewage pump lifting pressure pipe 3 is connected to the outlet of the cylinder body 1. A water inlet pipe 6 is provided on the cylinder wall of the body 1, and a basket grid 5 is connected to the water inlet pipe 6. The basket grid 5 includes a box body, and a filter screen or a grid is provided at the bottom of the box body. It is characterized in that A water receiving pipe 7 is connected to the bottom of the box body, and the outlet of the water receiving pipe 7 faces the bottom of the cylinder body 1 . The utility model can further take optimization technical measures:

The bottom of the cylinder body 1 is a V-shaped bottom; the outlet of the water pipe 7 faces the upper part of the V-shaped bottom of the cylinder body 1, so that the water rushes to the upper part of the V-shaped bottom and then flushes along the V-shaped bottom to the bottom of the V-shaped bottom where the dirt accumulates. .

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the pump station includes a cylinder body 1, a submersible sewage pump 2, a submersible sewage pump lifting pressure pipe 3, a water outlet pipe 4, a basket grille 5, a water inlet pipe 6, a water connection pipe 7 and a grouting port 8. The bottom of the cylinder has a specially designed anti-silting V-shaped structure. A platform is designed to support the coupling base at the bottom of the cylinder. The platform is 20~30cm higher than the bottom of the cylinder, and the bottom of the cylinder at the lower end of the water inlet has a slope. Make the bottom of the barrel form a V shape.

As shown in Figure 1, the basket grille is installed at the water inlet. The basket grille can be cylindrical or square. The upper part of the basket grille has a movable top cover for cleaning garbage. The lower part of the basket grille is Filter screen or grating, the basket grille is surrounded by thin walls, and a circular hole is opened on one side to connect with the water inlet. match. The outlet of the water connection pipe is directly facing the bottom of the cylinder body. When water enters, the water flow will have an impact effect on the bottom of the cylinder body, effectively preventing dirt from settling and accumulating.

When the submersible sewage pump stops running, the specially designed bottom only allows a small amount of sewage to stay in the pump pit. When the pump starts up again, the water pouring down from the water inlet scours the bottom of the cylinder, and the large flow rate formed by the pump starting operation It can achieve the effect of self-cleaning, solve the problem of manual dredging, eliminate the peculiar smell inside the pump station, and ensure the cleanliness of the pump station. The concrete bottom of traditional pumping stations generally adopts a flat bottom structure, usually with serious sludge accumulation, and manual dredging is required periodically to ensure the normal use of the pump. This work is not only cumbersome, but also poses certain dangers to dredgers. Compared with the concrete flat bottom of the traditional pumping station, the V-shaped structure of the bottom of the integrated pumping station with water impact V-shaped structure solves the problem that the traditional pumping station cannot solve, greatly saving time and manpower.

It should be noted that the above are only preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Equivalent transformations made on the basis of the above examples all belong to the protection scope of this example.
