Problems solved by technology

[0002] At present, there are many problems in the drainage system, such as leakage, back odor, noise, etc., especially the problems of leakage, pipe blockage, sewage overflowing into the room, and back odor pollution. In order to solve the above problems, many technicians have focused on the above problems Different solutions are proposed: 1. In the special single riser system, a hollow water flow is formed by setting a water channel at the junction of the horizontal pipe and the standpipe, so as to improve the ventilation capacity of the drainage standpipe and reduce the odor return of the floor drain; 2. Adopt Double standpipe method, set up a special ventilation pipe to reduce the problem of floor drain odor return; 3. Adopt double standpipe self-circulation mode to improve the exhaust capacity of the standpipe and reduce the problem of floor drain odor return; 4. In the special long joint single standpipe system, Because the riser pipe is partially enlarged, it has a certain impact on interior decoration and occupies indoor space; the above technologies have solved the problem of floor drains to varying degrees, but none of them can solve the problems of blocked sewage overflow and silt deposition

Embodiment 1

[0023] Such as figure 1 As shown, a kind of anti-backflow and anti-silt pipeline access device, it comprises standpipe connection pipe 4, has the sewage discharge pipe 9 of water-sealed sewage discharge inlet 10, has the waste water discharge pipe 7 of waste water discharge inlet 8, air pressure adjustment Box 11, water-sealed box 1 and the water-sealed split hanging plate 6 arranged in the water-sealed box 1, wherein the top of the water-sealed split hanging plate 6 is hinged to the inner side of the top box wall of the water-sealed box 1, and the The riser connecting pipe 4 is arranged through the water seal box 1, and the riser connecting pipe 4 is provided with a drain port 5; When it is on the wall, the water-sealed partition hanging plate 6 divides the water-sealed box into two boxes that are not connected to each other, and the drain port 5 is located in one of the boxes, and the other box is provided There is a water inlet 2; the bottom of the water-sealed box 1 is pr...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that one end of the sewage drainage pipe passes through the top wall of the water-sealed tank and communicates with the riser connecting pipe, so as to adapt to different drainage methods or structures.

Embodiment 3

[0032] The main difference between this embodiment and Embodiment 1 is that the sewage drainage pipe is arranged above the water-sealed box, that is, one end of the sewage drainage pipe is directly connected with the riser connecting pipe, so as to adapt to different drainage methods or drainage structure.

Abstract

The invention provides a pipeline connection device for preventing overflow return and sludge. The device comprises a riser connecting pipe, a water sealing tank and a water sealing and dividing hanging plate, wherein the top end of the water sealing and dividing hanging plate is hinged with the inner side of the tank wall at the top of the water sealing tank; the riser connecting pipe penetrates through the water sealing tank and is provided with a draining port; when the bottom end of the water sealing and dividing hanging plate supports against the tank wall of the water sealing tank, the water sealing tank is divided into two tank bodies which are not mutually communicated by using the water sealing and dividing hanging plate; the draining port is arranged in one tank body; a water feeding port is arranged on the tank wall of the other tank body; a tank body separating board is arranged at the bottom of the water sealing tank and is positioned between the riser connecting pipe and the water sealing and dividing hanging plate; the top of the tank body separating board is lower than the tank wall at the top of the water sealing tank and is not lower than the bottom end of the water sealing and dividing hanging plate; and the lowest part of the draining port is level with the bottom of the water sealing tank. The device has the advantages of scientific design, reliable performance and capabilities of automatically sealing and preventing overflow return and sludge.
