In order to overcome the defects of the background technology, the utility model provides a flocculation sedimentation tank for sewage treatment, which mainly solves the problem that a filter tube assembly of the existing flocculation sedimentation tank is blocked.

The technical scheme adopted by the utility model is as follows:

a flocculation sedimentation tank for sewage treatment, which comprises a housin, the casing is equipped with inlet tube, pond and outlet pipe, inlet tube and outlet pipe all communicate with the pond, be equipped with a plurality of filter tube subassemblies in the pond, filter tube subassembly includes if parallel arrangement's filter tube, filter tube subassembly below is equipped with stores up mud chamber, the casing is equipped with the jet-propelled pipe of being connected with the air supply, filter tube one end with jet-propelled pipe sets up relatively, the other end with store up mud chamber and set up relatively.

The shell is internally provided with a total air pipe, and a plurality of air ejector pipes are communicated with the total air pipe.

The shell is internally provided with a water inlet cavity and a water filtering cavity, the water inlet cavity and the water filtering cavity are separated by a partition board, and the bottom of the partition board is provided with a through groove for communicating the water inlet cavity and the water filtering cavity.

The water inlet cavity is connected with the water inlet pipe.

The bottom of the shell is provided with a valve communicated with the mud storage cavity.

The bottom of casing is the funnel-shaped structure, store up mud chamber and locate the bottom of casing inner chamber.

And a sedimentation cavity is further arranged in the shell, and the water outlet pipe is communicated with the sedimentation cavity.

The beneficial effects of the utility model are as follows: the utility model provides a flocculation sedimentation tank for sewage treatment, which can blow off dust at the upper end of a filter tube assembly by using high-pressure gas, thereby reducing the possibility of blockage.

Detailed Description

The utility model is further described below with reference to the accompanying drawings: as shown in the figure, a flocculation sedimentation tank for sewage treatment comprises a shell 1, the shell is equipped with inlet tube 2, pond 3 and outlet pipe 4, inlet tube and outlet pipe all communicate with the pond, be equipped with a plurality of filter tube assemblies 5 in the pond, filter tube assemblies include if parallel arrangement's filter tube 51, filter tube assembly below is equipped with stores up mud chamber 52, the shell is equipped with the jet tube 6 of being connected with the air supply, filter tube one end with the jet tube sets up relatively, the other end with store up mud chamber and set up relatively. The high-pressure gas can be utilized to blow off dust at the upper end of the filter tube assembly, dust in the pipeline is blown off, the possibility of blockage is reduced, and the air injection tube is connected with the air pump.

In this embodiment, as shown in the figure, a main air pipe 60 is disposed in the housing, and a plurality of air injection pipes are communicated with the main air pipe. The shell is provided with a main air pipe interface 601 communicated with a main air pipe to realize ventilation.

In this embodiment, as shown in the figure, the housing is provided with a water inlet chamber 11 and a water filtering chamber 12, the water inlet chamber and the water filtering chamber 12 are separated by a partition plate 13, and a through groove 131 for communicating the water inlet chamber and the water filtering chamber is formed at the bottom of the partition plate. After entering, water enters the water tank through the through groove and then enters the water filtering cavity, then enters the water tank through the water inlet pipe, and water vapor rises along with the filter pipe, and soil descends to the mud storage cavity.

In this embodiment, as shown in the figure, the water inlet chamber is connected to the water inlet pipe.

In this embodiment, as shown, the bottom of the housing is provided with a valve 14 in communication with the mud storage cavity. The muddy water flow can be controlled.

In this embodiment, as shown in the figure, the bottom of the housing is in a funnel-shaped structure, and the mud storage cavity is disposed at the bottom of the inner cavity of the housing. The mud water is more beneficial to aggregation and is convenient to discharge.

In this embodiment, as shown in the figure, a sedimentation chamber 15 is further disposed in the housing, and the water outlet pipe is communicated with the sedimentation chamber. The water is discharged after precipitation, so that the impurities in the water are further reduced.
