Description

Anti-backflow deodorization device for sewer pipe

Technical Field

The utility model belongs to the technical field of drainage equipment, and particularly relates to a backflow-preventing and deodorizing sewer pipe device.

Background

In the drainage system of the building, water devices of each household, such as a water tank, a flush toilet and the like, are connected into a sewer branch pipe, and then the sewer branch pipe is connected into a sewer main pipe of the building. When the main pipe is blocked, sewage discharged by upper-layer households can flow backward along the branch pipe to enter lower-layer households, so that household pollution, furniture damage and the like of the lower-layer households are caused. And present anti-backflow device is only one removable cover, and the slag charge in the offal can block on removable cover from time to time, leads to removable cover can not closed totally to can not block the water and flow backward, simultaneously in the offal that has the dross, the dross often can come the water level at removable cover and bond, thereby influence removable cover's closure, so simultaneously, even if water does not flow backward, but also can escape in the downcomer unpleasant smell, influence sanitation.

Therefore, the key point for solving the problems is to design the anti-backflow device for the sewer pipe, which has a simple structure, can prevent sewage and odor from flowing backwards and is deodorant. The utility model discloses a backflow-preventing sewer pipe, which comprises a core pipe and a plurality of side pipes connected with the core pipe, wherein the utility model has the Chinese patent application number of CN 201822209711.6, the application publication number of CN207226868U, the application publication number of 2018.12.27 and the application publication number of 2019.10.15; the side pipe comprises a deodorization backflow prevention device, a deodorization sewage drainage drainer and a plurality of water pipe pipelines which connect the deodorization backflow prevention device, the deodorization sewage drainage drainer and the core pipe together; an overflow head is arranged above the core pipe; the deodorizing and backflow preventing device comprises a deodorizing core, a turning plate and a deodorizing rubber pad, wherein the turning plate can prevent water of a water pipe from flowing backward, the deodorizing rubber pad can prevent odor between the turning plate and a water hole of the deodorizing core, the deodorizing rubber pad is arranged on the turning plate, and the turning plate is rotatably connected to the deodorizing core. Through install additional on the side pipe and prevent flowing backward and put, can effectively avoid pouring into other side pipes after certain side pipe intakes when nuclear core tube blocks up. When water flows backwards from the lower part, the water flows backwards and overflows from the overflow head, and the dredging function can be effectively realized.

However, the deodorization and backflow prevention effect is limited, and the situation that the backflow prevention device is not sealed can occur in use, so that further improvement is still needed.
