Problems solved by technology

However, there are many kinds of impurities in the sewage, especially a large amount of sludge contained in the sewage, which settles under the action of its own gravity. If the sewage enters the water treatment device, a large amount of sludge will settle to the bottom of the water treatment device, and the liquid medicine is difficult to Purify the settled sludge, thereby reducing the purification effect of the sewage; at the same time, the sedimentation of the sludge in the water treatment device will also affect the performance of the water treatment device, part of the liquid medicine enters the sludge layer, not only cannot purify the sludge, It cannot be fully mixed with sewage to achieve the purification effect, resulting in low efficiency and waste of liquid medicine in the process of sewage treatment

Embodiment 1

[0029] In view of the phenomena of serious sludge settlement, insufficient mixing of liquid medicine and serious waste of liquid medicine in the existing sewage purification treatment, this embodiment is optimized to solve the problems in the prior art.

[0030] Specifically, such as figure 1 and figure 2 As shown, the present embodiment provides a sewage purification device for preventing sludge from settling, including a box body 1, and a water inlet 2 is vertically arranged above the box body 1; a dosing device is provided in the box body 1, and the dosing device includes Vertical rigid dosing pipe 5, the upper end of the rigid dosing pipe 5 extends from the water inlet 2 to the outside of the box body 1, and the lower end of the rigid dosing pipe 5 extends to the lower part of the box body 1; the upper end of the rigid dosing pipe 5 Connected with a stirring device, the stirring device includes a passive vane 3 that rotates relative to the rigid dosing tube 5, and the pa...

Embodiment 2

[0045] This embodiment discloses a sewage purification device that prevents sludge from settling. Compared with Embodiment 1, the structure of the rigid dosing pipe is improved, as follows:

[0046] Such as Figure 4 As shown, the present embodiment optimizes the drug discharge structure of the rigid drug feeding tube 5, and adopts another feasible option: the lower tube wall of the rigid drug feeding tube 5 is provided with several drug outlets 10, and the drug outlet The mouth 10 is towards the periphery of the rigid dosing tube 5 . When such a solution is adopted, the drug outlet 10 at the lower part of the rigid drug feeding tube 5 is arranged on the tube wall in a 360° direction.

[0047] Preferably, when such a solution is adopted, the lower port of the rigid drug feeding tube 5 is closed. It can be closed with end caps, plugs, etc., or directly welded and closed at the port.

[0048] Other components and structures in this embodiment are the same as those in Embodime...

Abstract

The invention relates to the technical field of sewage treatment, and especially relates to a sewage purification device capable of preventing sludge sedimentation. The sewage purification device comprises a box body, and a water inlet is vertically formed in the upper part of the box body; a chemical feeding device is arranged in the box body and comprises a vertical rigid chemical feeding pipe, the upper end of the rigid chemical feeding pipe extends out of the box body from the water inlet, and the lower end of the rigid chemical feeding pipe extends to the lower part of the box body; the rigid dosing pipe is sleeved with a stirring device, the stirring device comprises a driven blade rotating relative to the rigid dosing pipe, and the driven blade is located below the water inlet; and the stirring device further comprises a disturbance blade connected to the lower portion of the rigid dosing pipe in a sleeving mode, and the disturbance blade and the driven blade rotate synchronously and push liquid at the bottom of the box body upwards. Stirring can be realized by using the falling kinetic energy of sewage, so that the sewage in the box body is kept in a turbid liquid state, the sedimentation of sludge is avoided, the mixing degree of liquid medicine and the sewage is improved, the waste of the liquid medicine is also reduced, and the sewage purification effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a sewage purification device for preventing sludge settlement. Background technique [0002] At present, when municipal sewage is treated, it is often carried out by adding liquid medicine to the interior of the sewage to purify the sewage. However, there are many kinds of impurities in the sewage, especially a large amount of sludge contained in the sewage, which settles under the action of its own gravity. If the sewage enters the water treatment device, a large amount of sludge will settle to the bottom of the water treatment device, and the liquid medicine is difficult to Purify the settled sludge, thereby reducing the purification effect of the sewage; at the same time, the sedimentation of the sludge in the water treatment device will also affect the performance of the water treatment device, part of the liquid medicine enters the sludge layer, not only cannot...
