Description

Technical Field

[0001] The utility model belongs to the field of sewage lifting devices, and in particular relates to a sewage lifting device for separating foreign matter. Background Art

[0002] At present, underground stations, tunnels and other underground places have tried to use sewage lifting devices to collect, lift and discharge sewage into the sewage network. The sewage lifting device mainly includes a water tank and a sewage pump. Due to the large amount of domestic sewage, there are often many solid impurities in the sewage, which can easily cause the solid impurities to settle at the bottom of the water tank, making it difficult to clean and even blocking the water outlet and water inlet pipes. In addition, there is a lot of odor in the sewage. If the sewage cannot be treated in time, the odor will be greatly aggravated, causing trouble to users.

The sewage lift includes an odor removal device, an impurity crushing device, a sewage filter and a lifting pump. A deodorizer is installed on the outer wall of the odor removal device. The air intake pipe of the deodorizer passes through the top of the odor removal device and extends into the odor removal device. The water inlet of the odor removal device is connected to the external sewage discharge device, the water outlet of the odor removal device is connected to the water inlet of the impurity crushing device, the water outlet of the impurity crushing device is connected to the water inlet of the sewage filter, the water outlet of the sewage filter is connected to the lifting pipe, and the lifting pump is arranged on the lifting pipe. The present application solves the technical problems that the pipeline is blocked by solid impurities in the sewage lift and the odor generated by the sewage is difficult to remove. However, when the sewage of the sewage lift in the application passes through the first liquid seal part, the heavier objects such as gravel and metal in the sewage are easy to stay in the first liquid seal part, resulting in the blockage of the first liquid seal part.

[0004] In view of this, the present utility model is proposed. Utility Model Content
