Drainage and pollution discharge trough

Abstract

The invention provides a drainage and pollution discharge trough, comprising a trough body used for pollution discharge, wherein the section of the trough body is U-shaped, protrusive pollution separation ribs are respectively arranged on the two side walls of the U-shaped trough body, and the pollution separation ribs face downwards to form acute angles with the side walls. The invention adopts the principle that in the drainage and pollution discharge process, solid excrement in common sewage from any direction is prevented from being contacted with the side wall of the trough body through the stopping and guiding effects of the pollution separation ribs when entering the trough body, furthermore, the blockage caused by solid excrement adhered and attached to the side wall is avoided, the solid excrement in the sewage can be easily centralized and guided to the middle part of the trough body, and the drainage of sewage is enabled to be rapider and more thoroughly.

Description

technical field [0001] The invention relates to the field of drainage and sewage systems, in particular to a drainage and sewage tank. Background technique [0002] At present, the existing drainage and sewage tank structure has a simple open-air straight tank in appearance, and the inner surface (bottom surface and side wall) of the drainage tank is a smooth whole plane, and the structure is simple. In the process of drainage and sewage, limited by the side walls of the drainage tank, the discharge flow in the middle of the tank is large, and the discharge flow on both sides near the side walls is small, and the discharge is in the form of staggered and reticulated water patterns. Therefore, the drainage and sewage grooves of this structure can easily cause excrement (especially solid excrement) to drift toward the side wall and lose the driving force for removal, resulting in increased difficulty in removal. In addition, the solid excrement falling from the open upper su...

AI Technical Summary

Problems solved by technology

Therefore, the drainage and sewage grooves of this structure can easily cause excrement (especially solid excrement) to drift toward the side wall and lose the driving force for removal, which increases the difficulty of removal

In addition, the solid excrement falling from the open upper surface is easy to stick or stay on the side wall, which is difficult to remove

Therefore, although the structure of the drainage and sewage tank used in reality is simple in structure, the drainage and sewage discharge effect is not good. During operation, solid excrement tends to be close to the side wall of the drainage tank, resulting in incomplete and thorough drainage.

The excrement stays in the tank for a long time, not only the environment is easy to deteriorate, but also it is easy to produce highly adherent dirt, which will damage the self-lubricating and self-cleaning functions of the PVC tank
