Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device for living areas. Background Technique

[0002] Domestic sewage is the wastewater discharged in the daily life of residents, mainly from residential buildings and public buildings, such as residences, government agencies, schools, hospitals, stores, public places, and the toilets of industrial enterprises. The pollutants contained in domestic sewage are mainly organic matters. The organic matters existing in domestic sewage are extremely unstable and easily rot to produce malodors. Bacteria and pathogens multiply in large numbers with the organic matters in domestic sewage, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before being discharged; in the treatment of sewage, it needs to be preliminarily filtered, but if the filter residue is not cleaned in time during the filtration, it will affect the subsequent filtration work.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A sewage treatment device for living areas includes a base and a fixed cylinder located thereon. A filtering drum is arranged inside the fixed cylinder. One end of the filtering drum is supported by an annular support seat connected to the inner wall of the fixed cylinder, and the other end is connected to the output end of a driving unit. The driving unit is fixed to the end of the fixed cylinder through a connecting seat. The end of the filtering drum away from the driving unit is of an open structure. A slag discharge port and a filtering port are respectively arranged at the bottom of the fixed cylinder. The slag discharge port is located below the open structure, and the filtering port is located below the filtering drum. A liquid inlet pipe is arranged at the end of the fixed cylinder, and the end of the liquid inlet pipe extends into the filtering drum. A material guiding mechanism is arranged on the inner wall of the filtering drum.

[0006] Preferably, the material guiding mechanism includes spiral guiding vanes installed on the inner wall of the filtering drum.

[0007] Preferably, one end of the liquid inlet pipe located inside the filtering drum is connected with a bottom plate through a connecting plate. The bottom plate is inclined, and a plurality of V-shaped plates are arranged on the top of the bottom plate, and the tips of the V-shaped plates are arranged towards the high point of the bottom plate.

[0008] Preferably, the base is connected to the fixed cylinder through connecting bolts, and buffer washers are arranged on the connecting bolts, and the buffer washers are located between the fixed cylinder and the base.

[0009] Preferably, a maintenance door is arranged on the outer wall of the fixed cylinder.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the present utility model, sewage is discharged from the liquid inlet pipe, impacts on the bottom plate, and is dispersed under the action of the V-shaped plate, then falls into the filtering drum for filtration. The filtered liquid enters the filtering port and is discharged, while the filter residue is driven by the spiral guiding piece to move to the end of the filtering drum and falls into the slag discharge port for discharge, completing the solid-liquid separation. This process can be carried out continuously, improving the filtration efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Refer to Figures 1-4, A domestic sewage treatment device, including a base 1 and a fixed cylinder 2 located thereon. A filter drum 10 is arranged inside the fixed cylinder 2. One end of the filter drum 10 is supported by an annular support seat 7 connected to the inner wall of the fixed cylinder 2, and the other end is connected to the output end of a driving unit 5. The driving unit 5 is fixed to the end of the fixed cylinder 2 through a connecting seat 12. The end of the filter drum 10 away from the driving unit 5 is of an open structure. The bottom of the fixed cylinder 2 is respectively provided with a slag discharge port 8 and a filter port 9. The slag discharge port 8 is located below the open structure, and the filter port 9 is located below the filter drum 10. An inlet pipe 4 is arranged at the end of the fixed cylinder 2, and the end of the inlet pipe 4 extends into the interior of the filter drum 10. A material guiding mechanism is arranged on the inner wall of the filter drum 10.

[0019] Sewage is discharged from the inlet pipe 4, impacts on the bottom plate 13, and is dispersed under the action of the V-shaped plate 14, then falls into the filter drum 10 for filtration. The filtered liquid enters the filter port 9 and is discharged, while the filter residue is driven by the spiral guiding sheet 11 to move to the end of the filter drum 10 and falls into the slag discharge port 8 for discharge, completing solid-liquid separation. This process can be carried out continuously to improve the filtration efficiency.

[0020] In this implementation scheme, the material guiding mechanism includes a spiral guiding sheet 11 installed on the inner wall of the filter drum 10, which aggregates the filter residue and continuously discharges it from the filter drum 10.

[0021] In this implementation scheme, one end of the inlet pipe 4 located inside the filter drum 10 is connected with a bottom plate 13 through a connecting plate 15. The bottom plate 13 is inclined, and several V-shaped plates 14 are arranged on the top of the bottom plate 13, and the tips of the V-shaped plates 14 are oriented towards the high point of the bottom plate 13 to disperse the sewage and prevent the sewage from gathering in one place, affecting the filtration efficiency.

[0022] In this implementation scheme, the base 1 is connected to the fixed cylinder 2 through connecting bolts, and buffer washers 3 are arranged on the connecting bolts. The buffer washers 3 are located between the fixed cylinder 2 and the base 1, playing a buffering role and also preventing hard contact between the two, generating noise.

[0023] In this implementation scheme, a maintenance door 6 is arranged on the outer wall of the fixed cylinder 2, which is convenient to open for maintaining its interior.

[0024] The above is only a preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
