Embodiment 1

[0031] combined with figure 1 As shown, a kind of anti-backflow drainage system includes drainage branch pipe 5, water collection pipe 2 and discharge pipe 3 connected in sequence, and a rectangular anti-backflow box 1 is arranged between the water collection pipe 2 and discharge pipe 3. The top of the anti-backfill box 1 is provided with a water inlet 11 connected to the water collection pipe 2, and the bottom part is provided with a water outlet 12 connected to the discharge pipe 3. The anti-backfill box 1 is provided with a size larger than the water inlet 11 and cannot The floating block 4 passing through the water outlet 12.

[0032] Implementation principle:

[0033] The density of the floating block 4 is less than that of water, and it is in a floating state in the water.

[0034] Under normal drainage conditions, the water is collected into the water collection pipe 2 through the drainage branch pipe 5, and then flows through the anti-backflow tank 1 and the discharg...

Embodiment 2

[0038] On the basis of Example 1, in conjunction with the attached image 3 As shown, the water inlet 11 and the water outlet 12 are arranged on the opposite side elevation of the anti-pouring tank 1, and the water stop block 41 included in the floating block 4 is fixed on the water stop block 41 The connecting column 42 and the hollow plate 43 fixed at the end of the connecting column 42 , the connecting column 42 is perpendicular to the hollow plate 43 , and the size of the hollow plate 43 is larger than the water outlet 12 .

[0039] Implementation principle:

[0040] It is worth noting that the shape and structure of the hollow plate 43 are not limited, as long as it cannot pass through and will not block the water outlet 12; 1 on the same side elevation, that is, on the adjacent or opposite side elevation, the water stop block 41 faces the water inlet 11, the hollow plate 43 faces the water outlet 12, and the connecting column 42 can be L-shaped or linear. In this embo...

Embodiment 3

[0044] On the basis of Embodiment 2, further, the overall maximum length and width of the water stop block 41 , the connecting column 42 and the hollow plate 43 are adapted to the length and width of the anti-backflow box 1 .

[0045] Implementation principle:

[0046] The overall maximum length and width of the water stop block 41, the connecting column 42 and the hollow plate 43 are adapted to the length and width of the anti-inverting box 1, that is, the length and width of the floating block 4 and the anti-inverting box 1 Correspondingly, the floating block 4 cannot move arbitrarily in the anti-inverting box 1, but can only move up and down in the height direction of the anti-inverting box 1 with the water level, and the water-stopping block 41 is always attached to the inflowing box 1. On the side elevation where the water inlet 11 is located, when the sewage flows back, the water stop block 41 can rise straight up to block the water inlet 11, so that the speed of prevent...

Abstract

The invention discloses an anti-backflow drainage system. The system includes a drainage branch pipe, a water collecting pipe and a discharge pipe, wherein the drainage branch pipe, the water collecting pipe and the discharge pipe are connected in sequence, a rectangular-block-shaped anti-backflow box is arranged between the water collecting pipe and the discharge pipe, the upper portion of the anti-backflow box is provided with a water inlet connected with the water collecting pipe, the lower portion of the anti-backflow box is provided with a water outlet connected with the discharge pipe, and the anti-backflow box is internally provided with a floating block which is larger than the water inlet in size and can not pass through the water outlet. Through the arrangement of the anti-backflow box, when backflow of sewage occurs, water flow and characteristics of buoyancy are made use of, the floating block automatically blocks the water inlet of the anti-backflow box, further backflow of sewage is prevented, without affecting free drainage of the drainage system, the problem that backflow is easy to occur in a drainage system in the prior art is solved, the structure is simple, the system is easy to maintain, and no additional energy is consumed.

Description

technical field [0001] The invention relates to the field of drainage systems, in particular to an anti-backwash drainage system. Background technique [0002] Drainage system is an important part of modern architecture, and whether the drainage system is smooth or not is related to the quality of people's life. The drainage system generally adopts artesian drainage. Artesian drainage has the advantages of relatively low construction cost, simple maintenance, energy saving and environmental protection. Sewage flooding occurs. Sewage backflow will cause damage to buildings, pollute the environment, breed germs, not only destroy the living environment, but also cause economic losses, and even cause personal casualties in severe cases. Contents of the invention [0003] The object of the present invention is to provide an anti-backflow drainage system, which is used to solve the problem that the drainage system in the prior art is prone to backflow. [0004] The present in...
