Description

Technical Field

[0001] This utility model relates to the field of environmental protection, specifically to a sampling device in the process of domestic sewage treatment. Background Technology

[0002] Sampling raw sewage and analyzing data such as COD, BOD, ammonium, and nitrogen is an important task of wastewater treatment plants. Raw water sampling has gradually evolved from early manual sampling to automatic sampling. Automatic sampling relies on sampling pumps installed in the raw water inlet tank. The sampling pumps work in conjunction with a controller to deliver raw water to the plant's laboratory at regular intervals and in measured quantities.

[0003] In addition to organic matter, domestic sewage contains a large amount of solid impurities, such as silt, paper, hair, and household garbage. High levels of these solid impurities can easily clog sampling pumps, affecting automatic sampling. To avoid this problem, some factories choose to upgrade their pipe networks, using flushing and backwashing to unclog the sampling pumps and pipelines. However, for factories with limited space, accommodating and arranging such pipe networks can be quite difficult. Utility Model Content

[0004] This utility model provides a protective device for removing larger solid impurities from domestic sewage through filtration. The main technical solution adopted is as follows:

[0005] A protective device for a domestic sewage sampling pump includes a raw water inlet tank, on which a floor is laid. An inspection port is provided on the floor, located above and connected to the raw water inlet tank. The key feature is:

[0006] A support is provided at the inspection port. The top of the support is fixedly connected to the floor around the inspection port. A water intake filter is provided on the support. The lower part of the water intake filter extends downward into the raw water inlet tank. The lower part of the water intake filter has several filter holes. The interior of the water intake filter forms a water intake area, and a sampling pump is placed in the water intake area.

[0007] The size of the filter holes can be set according to the actual situation. The filter holes on the water intake filter can isolate larger solid impurities in the raw water and prevent the sampling pump from getting clogged. Attached Figure Description

[0013] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0014] like Figures 1-5 As shown, a protective device for a domestic sewage sampling pump includes a foundation, on which a raw water inlet trough 1 is provided. A concrete floor 2 is laid above the raw water inlet trough 1. An inspection port is provided on the floor 2. The inspection port is located above and connected to the raw water inlet trough 1. A protective grille is laid on the inspection port.

[0015] A bracket 3 is provided at the inspection port. The top of the bracket 3 is fixedly connected to the floor 2 around the inspection port (i.e., the wall of the inspection port). A water intake filter 4 is provided on the bracket 3. The lower part of the water intake filter 4 extends downward into the raw water inlet tank 1. The lower part of the water intake filter 4 is provided with several filter holes. The size of the filter holes is adjusted according to the actual situation and needs of the plant area. Preferably, the diameter of the filter holes is relatively large (e.g., 10mm) to filter large solid impurities in the raw water. The interior of the water intake filter 4 forms a water intake area. A sampling pump is placed in the water intake area. The outlet of the sampling pump is connected to a water intake hose.

[0016] The support 3 includes two vertically arranged T-shaped steels 31, two vertically arranged angle steels 32, and two horizontally arranged flat steels 33. The two flat steels 33 are distributed vertically, and their two ends are fixedly connected to the two angle steels 32 respectively. The upper part of the angle steels 32 is fixedly connected to the floor 2 around the inspection port by expansion bolts. The web of the T-shaped steels 31 is welded to the two flat steels 33. The support 3, made of T-shaped steels 31, angle steels 32, and flat steels 33, has a simple and sturdy structure.

[0017] Two sliders 6 are provided on the water intake filter bucket 4, and each slider 6 corresponds to a T-shaped steel 31. Each slider 6 has a T-shaped groove that matches the cross-section of the T-shaped steel 31. The slider 6 slides and moves up and down with the T-shaped steel 31 through the T-shaped groove. This facilitates the assembly and removal of the water intake filter bucket 4 during maintenance and cleaning.

[0018] The water intake filter 4 includes a back plate 41, an arc-shaped plate 42, and a bottom plate 43. The back plate 41 is a flat plate and is vertically arranged. Both sliders 6 are fixed to the back plate 41. The two straight edges of the arc-shaped plate 42 are fixedly connected to the two vertical edges of the back plate 41. The bottom plate 43 is horizontally arranged and connected to the bottom of the back plate 41 and the arc-shaped plate 42. The lower part of the back plate 41 and the arc-shaped plate 42 has several filter holes. The back plate 41, the arc-shaped plate 42, and the bottom plate 43 are made of stainless steel. The water intake filter 4 has a simple structure and is easy to quickly mold.

[0019] The top of the back plate 41 and the arc plate 42 are respectively fixed with handles 5 for easy operation.

[0020] Beneficial effects: By adopting the technical solution of this utility model, a water intake filter can be installed outside the sampling pump to isolate larger solid impurities in domestic sewage outside the water intake filter, thereby delaying and avoiding blockage of the water intake pump / water intake pipeline, and ensuring continuous and stable sampling of incoming water from the sewage treatment plant.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
