污水箱

Abstract

本实用新型属于清洁设备技术领域，公开了一种污水箱，包括箱体，箱体内设置有隔板，隔板被配置为分隔箱体的内部空间以形成第一污水腔和第二污水腔，第一污水腔用于存储污液，第二污水腔用于储存气液分离后的污液，第一污水腔和第二污水腔相连通，箱体内设置有与第一污水腔连通的抽污管，箱体内还设置有与第二污水腔连通的抽气管，抽气管的端部连接有抽吸装置，抽吸装置用于对第一污水腔形成负压以将外部污水通过抽污管抽入箱体内。污水箱通过在箱体内设置隔板，能够将箱体的内部空间分隔为第一污水腔和第二污水腔，在隔板的隔挡下，污液则被隔挡在第一污水腔中，避免污液进入第一污水腔后通过抽气管进入到抽吸装置内，降低了抽吸装置故障率。

Claims

1. A sump tank comprising a tank body, characterised in that, The box is equipped with a partition (11) configured to separate the internal space of the box to form a first sewage chamber (111) and a second sewage chamber (112). The first sewage chamber (111) is used to store sewage, and the second sewage chamber (112) is used to store sewage after gas-liquid separation. The first sewage chamber (111) and the second sewage chamber (112) are connected. The box is equipped with a sewage suction pipe (12) connected to the first sewage chamber (111). The box is also equipped with an air suction pipe (13) connected to the second sewage chamber (112). The end of the air suction pipe (13) is connected to a suction device. The suction device is used to draw the gas in the first sewage chamber (111) into the second sewage chamber (112) so that the first sewage chamber (111) forms a negative pressure, and the external sewage is drawn into the first sewage chamber (111) through the sewage suction pipe (12).

2. The sump tank of claim 1, wherein, The top of the partition (11) has a gap with the inner top wall of the box so that the first sewage chamber (111) and the second sewage chamber (112) can communicate with each other.

3. The sump tank of claim 1, wherein, The sewage tank also includes a liquid-blocking component (3), which is located at the end of the air extraction pipe (13) in the second sewage chamber (112). The liquid-blocking component (3) is used to prevent sewage from entering the second sewage chamber (112).

4. The sump tank of claim 3, wherein, The liquid-blocking component (3) includes: A sleeve (31), one end of which is fitted onto the end of the suction pipe (13); A first baffle (32) is disposed on the outer periphery of the sleeve (31), the first baffle (32) extends toward the first sewage chamber (111), the first baffle (32) rests on the top of the partition (11), and there is a gap between the first baffle (32) and the inner top wall of the box.

5. The sump tank of claim 4, wherein, The two ends of the first baffle (32) are bent vertically toward the inner bottom wall of the box to form side baffles (321).

6. The sump tank of claim 4, wherein, The other end of the sleeve (31) abuts against the inner top wall of the box body. A second baffle (33) is also provided on the outer periphery of the sleeve (31). The second baffle (33) is spaced apart from the first baffle (32). The top end of the second baffle (33) abuts against the inner top wall of the box body. The end of the second baffle (33) is connected to the first baffle (32). A first channel (34) connecting the first sewage chamber (111) and the second sewage chamber (112) is formed between the first baffle (32) and the second baffle (33). The end edge of the sleeve (31) that abuts against the box body has a second channel (35) that communicates with the second sewage chamber (112).

7. The sump tank according to any one of claims 1-6, characterized in that, The second sewage chamber (112) is equipped with a detection probe, which is used to detect the amount of sewage in the chamber.

8. The sump tank according to any one of claims 1-6, characterized in that, The second sewage chamber (112) is provided with a filter element, which is located on the outer periphery of the sewage suction pipe (12) and is used to isolate impurities from external sewage.

9. The sump tank of claim 8, wherein, The filter element includes: The filter screen (4) has an open top and an installation hole on the bottom wall that matches the diameter of the suction pipe (12). The filter screen (4) is fitted onto the outer periphery of the suction pipe (12) through the installation hole and is snapped onto the inner bottom wall of the box.

10. The sump tank according to any one of claims 1-6, wherein, The enclosure includes: The main body (1) has an opening at its top and the partition (11) is disposed inside the main body (1). The cover (2) is rotatably connected to the body (1) and the cover (2) is sealed over the opening of the body (1).
