Description

Technical Field

[0001] The utility model relates to the technical field of domestic sewage from coal-fired power plants, in particular to a domestic sewage treatment device from coal-fired power plants. Background Art

[0002] The domestic sewage treatment device of a coal-fired power plant is a key facility to ensure that the domestic sewage of the power plant meets the discharge standards and realizes the rational reuse of water resources.

[0003] Since the submersible pump is directly submerged in domestic sewage, it is easy to cause blockage of the water inlet of the submersible pump, resulting in poor lifting effect. Garbage or pollutants may also cause impact or collision on various parts of the submersible pump, causing damage to the submersible pump. On the one hand, the maintenance workload is increased. On the other hand, when repairing the submersible pump, the submersible pump must be taken out of the sewage pool, which is extremely labor-intensive. The domestic sewage in the sewage pool is often accompanied by a foul odor, which affects the health of the maintenance personnel and makes maintenance work inconvenient.

[0004] The existing patent (publication number: CN214461080U) is a domestic sewage lifting device for a power plant, including a lifting pump, a water inlet of the lifting pump is connected to an inlet pipe, a water outlet of the lifting pump is connected to an outlet pipe, the inlet pipe extends into the sewage pool, the outlet pipe extends into the domestic sewage regulating tank, and a filter is installed in the inlet pipe. By adopting the technical solution of the utility model, a horizontal self-priming pump installed on the ground is used to replace the submersible pump to lift domestic sewage. The domestic sewage does not submerge the horizontal self-priming pump, will not cause blockage to the horizontal self-priming pump, will not cause damage to the horizontal self-priming pump, and reduces the maintenance workload. When the horizontal self-priming pump needs to be repaired, the personnel only need to perform maintenance on the ground, which reduces the labor intensity and has a larger space for maintenance work. By adding a stainless steel filter to pre-filter the domestic sewage, it can prevent garbage or other pollutants from damaging the horizontal self-priming pump, and at the same time reduce the maintenance workload.

[0005] In response to the above problems, existing patents have provided solutions. However, the above solutions have certain limitations during use. A grille is usually provided at the entrance of the domestic sewage treatment system. Most of the hair and other larger debris in the domestic sewage are blocked by the grille in front of the sewage inlet, which makes the grille more seriously blocked and inconvenient to clean.

[0006] Therefore, a domestic sewage treatment device for a coal-fired power plant is proposed. Utility Model Content
