[0002] It is usually necessary to set up a sewage pipe at the bottom of sewage treatment facilities such as flocculation tanks, sedimentation tanks, and filtration tanks to discharge the sludge settled in the sewage. During the long-term operation of the sewage treatment system, the connection between the equipment and the sewage pipe is particularly easy to be blocked, especially when the sludge is severely scaled and the poor fluidity easily causes sludge blockage. After the blockage, it is particularly troublesome to clean up, which will consume a lot of manpower and material resources, increase the operating cost and is not conducive to the long-term stable operation of the wastewater system. During the installation of the sludge pipe, the connection between the equipment and the sewage pipe is generally a flange connection, and the connection is the part where the sludge is most likely to accumulate and clog. When cleaning, it is necessary to first clean the sewage inside the equipment, then disassemble the flange connection, and clean the sludge inside the pipe. Sewage often splashes during the cleaning process, and it is difficult for the cleaning personnel to repair and the sanitary environment is also difficult to clean. Utility Model Content

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] The sewage discharge system of the utility model is as follows: Figure 2 As shown, it includes a sewage treatment device 11, a sewage connection device and a sewage pipe 12, and a sewage pump 13 is arranged on the sewage pipe 12, wherein the sewage treatment device 11 is used to treat sewage. Specifically, the sewage treatment device 11 can be one or more of a sedimentation tank, a flocculation tank, and a filtration tank. As long as it is a treatment device that produces sludge, it is applicable to the utility model. The sewage pipe 12 is used to transport the sludge to the sludge treatment device, and the sludge treatment device can be a sludge filter press and concentration device. The sewage pump 13 provides power for the transportation of the sludge, and the existing technology can be used.

[0018] The sewage connection device is used to connect the sewage treatment equipment 11 and the sewage pipe 12. The traditional sewage connection device is a flange. When the connection is blocked by sludge, the flange needs to be removed for dredging, which is troublesome to operate, and sludge and sewage will splash everywhere when the flange is removed.

[0019] In order to solve this problem, the sewage connection device of the utility model is as follows Figure 1 As shown, it includes a connector 1 with an inner cavity, the connector 1 is provided with a sewage inlet side wall 2 and a sewage outlet side wall 3, the sewage inlet side wall 2 and the sewage outlet side wall 3 are parallel to each other, and a sewage inlet port 4 is provided at the upper part of the sewage inlet side wall 2, a lower sewage cleaning port 5 is provided at the lower part of the sewage inlet side wall 2, an upper sewage cleaning port 6 is provided at the upper part of the sewage outlet side wall 3, and a sewage outlet 7 is provided at the lower part of the sewage outlet side wall 3, the sewage inlet port 4 is coaxial with the upper sewage cleaning port 6, and the sewage outlet 7 is coaxial with the lower sewage cleaning port 5; both the upper sewage cleaning port 6 and the lower sewage cleaning port 5 are provided with an openable and closable sewage cleaning door 8; a sewage outlet 9 is provided at the bottom of the connector 1, and an openable and closable switch member 10 is provided at the sewage outlet 9; the sewage inlet 4 is connected to a sewage treatment device 11, and the sewage outlet 7 is connected to a sewage discharge pipe 12.

[0020] The connector 1 has a certain cavity, which can play the role of transferring sludge. Specifically, the shape of the connector 1 can be cylindrical, preferably a rectangular parallelepiped. The connector 1 can be welded with corrosion-resistant metal plates, for example, made of stainless steel plates. The sewage inlet 4 is used to connect the sewage treatment equipment 11, and the sewage outlet 7 is used to connect the sewage pipe 12. Specifically, the sewage inlet 4 is connected to the sewage treatment equipment 11 through the first flange 14, and the sewage outlet 7 is connected to the sewage pipe 12 through the second flange 15. The sewage outlet 7 is arranged below the sewage inlet 4, which is conducive to the sludge entering the sewage pipe 12. After the sewage inlet 4 is connected to the sewage treatment equipment 11 and the sewage outlet 7 is connected to the sewage pipe 12, the sludge at the bottom of the sewage treatment equipment 11 can enter the sewage pipe 12 through the connector 1. The upper sewage cleaning port 6 is used to desilt the sewage inlet 4, and the lower sewage cleaning port 5 is used to desilt the sewage outlet 7. Since the sewage inlet 4 is coaxial with the upper sewage cleaning port 6, and the sewage outlet 7 is coaxial with the lower sewage cleaning port 5, after the dredging tool is inserted into the connector 1 through the upper sewage cleaning port 6, it can be directly inserted into the sewage inlet 4, thereby cleaning the sludge in the sewage inlet 4. Similarly, after the dredging tool is inserted into the connector 1 through the lower sewage cleaning port 5, it can be directly inserted into the sewage outlet 7, thereby cleaning the sludge in the sewage outlet 7. During normal operation, the sewage cleaning door 8 closes the upper sewage cleaning port 6 and the lower sewage cleaning port 5 to prevent the sludge from being discharged through the upper sewage cleaning port 6 and the lower sewage cleaning port 5.

[0021] Since sludge will accumulate in the connector 1, the sludge in the connector 1 must be discharged first during dredging. When dredging, the switch 10 is opened so that the drain outlet 9 is opened, and the sludge in the connector 1 can be discharged downward through the drain outlet 9. At the same time, the sludge in the drain inlet 4 and the drain outlet 7 can be discharged through the drain outlet 9 after being cleaned to the connector 1.

[0022] The specific desilting process of the utility model is as follows: when the sewage inlet 4 and the sewage outlet 7 are blocked by sludge, the switch 10 is first opened to open the sewage outlet 9, and the sewage and sludge inside the connector 1 are automatically discharged through the sewage outlet 9, so as to facilitate the subsequent desilting operation. After all the sewage and sludge inside the connector 1 are discharged, the sewage cleaning door 8 at the upper sewage cleaning port 6 and the lower sewage cleaning port 5 is opened. Since the sewage inlet 4 is coaxial with the upper sewage cleaning port 6, and the sewage outlet 7 is coaxial with the lower sewage cleaning port 5, the desilting tool can be inserted from the upper sewage cleaning port 6 and the lower sewage cleaning port 5, so that the desilting tool passes through the inner cavity of the connector 1 and extends into the sewage inlet 4 and the sewage outlet 7, so that the sludge blocked in the sewage inlet 4 and the sewage outlet 7 can be scraped into the connector 1, and the sludge is then discharged from the sewage outlet 9. After the desilting is completed, the switch 10 is closed, and the sewage cleaning door 8 at the upper sewage cleaning port 6 and the lower sewage cleaning port 5 is re-closed. Before desilting, the utility model can set a collecting device below the sewage outlet 9 to collect sludge and sewage to prevent sewage from splashing. During desilting, there is no need to remove connectors such as flanges, which makes the operation more convenient and labor-saving.

[0023] The sewage cleaning door 8 can be connected to the connecting body 1 by various existing connection methods. For example, the top of the sewage cleaning door 8 is connected to the connecting body 1 by a hinge, and the lower part is connected to the connecting body 1 by a lock. Preferably, the sewage cleaning door 8 is connected to the connecting body 1 by a plurality of bolts. In order to improve the sealing performance and prevent sewage leakage, a sealing gasket is provided between the sewage cleaning door 8 and the connecting body 1. The sealing gasket can be an elastic gasket such as a rubber gasket.

[0024] The switch member 10 may also adopt the structure of a switch door. For the convenience of operation, the switch member 10 may adopt a drain valve.

[0025] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
