Problems solved by technology

It has the following disadvantages: it only salvages the scum on the liquid surface of the water body, and cannot handle the suspended solid particles in the water body, resulting in low sedimentation efficiency and poor sedimentation effect, and its salvage structure is a rotating shaft parallel to the water surface. The drum type fishing plate may push the scum away during the rotation process and affect the fishing efficiency, and the fishing and transportation mechanism is relatively complicated

Embodiment 1

[0033] Such as figure 1 A kind of domestic sewage sedimentation device shown comprises a sedimentation box body, a water inlet pipe 30 and a water outlet pipe 40, and the sedimentation box body includes a primary sedimentation tank 10 and a secondary sedimentation tank 20 connected by an intermediate connecting pipe 50. The upper end of the primary sedimentation tank 10 is open, the upper end of the secondary sedimentation tank 20 is provided with a feeding port 1, the water inlet pipe 30 is arranged on the primary sedimentation tank 10 and is opposite to the intermediate connecting pipe 50, and the water outlet pipe 40 Set on the secondary settling tank 20 and opposite to the intermediate connecting pipe 50, the part below the outlet pipe 40 in the secondary settling tank 20 is a sludge sedimentation area, and the inlet pipe 30 and the intermediate connecting pipe 50 are provided with There is a solenoid valve 2, an on-off valve 3 is provided on the outlet pipe 40, a surface ...

Embodiment 2

[0039] The difference between this embodiment and embodiment 1 is:

[0040] Such as Figure 7 As shown, the transmission assembly 21 includes a rotating shaft 1 214 and a rotating shaft 2 215 respectively connected to the center of the driven pulley 7 and the driven pulley 19, and the first rotating shaft 214 and the second rotating shaft 215 are respectively provided with a gear 1 216 and Gear two 217, said gear one 216 and gear two 217 are positioned at the side opposite to conveyor belt one 4 of dividing plate 22, as Figure 8 As shown, the corresponding positions on the partition 22 are respectively provided with perforations 222 for the first rotating shaft 214 and the second rotating shaft 215 to pass through; between the first gear 216 and the second gear 217, there is a simultaneous meshing gear one 216 and gear two The transmission gear 218 of 217.

[0041] Others are the same as embodiment 1.

[0042] During application, rotating shaft 1 214 rotates with the rotat...

Embodiment 3

[0044] The difference between this embodiment and embodiment 2 is:

[0045] Such as Figure 9 As shown, the first gear 216 and the second gear 217 directly mesh with each other.

[0046] Others are the same as embodiment 2.

[0047] As mentioned above, after gear one rotates with rotating shaft one 214, driving gear two rotates, and gear two drives rotating shaft two 215 to rotate, and rotating shaft two 215 drives driven wheel three 19 to rotate, thereby can drive conveyor belt two 13 to run smoothly; At this moment, driven wheel three The rotation direction of 19 is opposite to the rotation direction of the driven pulley 7, and the adsorption plate 14 moves against the direction of water flow, which can better realize the adsorption of solid particles in the water body.

[0048] The specific application process of the above domestic sewage sedimentation device is as follows:

[0049] (1) Water intake: the domestic sewage to be treated is passed into the primary sedimentat...

Abstract

The invention discloses a domestic wastewater sedimentation device, and belongs to the field of water processing devices. The domestic wastewater sedimentation device comprises a first-stage sedimentation tank, a second-stage sedimentation tank, a water inlet pipe, a middle connecting pipe and a water outlet pipe. An above-water salvage mechanism and an underwater salvage mechanism are arranged inthe first-stage sedimentation tank. The above-water salvage mechanism comprises a longitudinally-inclining first conveying belt and a scooping plate arranged on the surface the first conveying belt.The first conveying belt and the scooping plate are each provided with mesh. A first torsional spring is arranged on the side, connected with the first conveying belt, of the scooping plate. A floating slag collecting plate is arranged at the upper end of the side, connected with the water inlet pipe, of the first-stage sedimentation tank. The underwater salvage mechanism comprises a transversely-horizontal second conveying belt and an adsorption plate arranged on the surface of the second conveying belt. The adsorption plate is provided with adsorption holes with aperture smaller than that ofthe mesh in the scooping plate. The aperture of the adsorption holes is gradually decreased from the sides, facing the water inlet pipe, of the adsorption holes to the opposite side. The above-waterfloating slag and underwater suspended solid particles can be removed first, sedimentation is then conducted, the sedimentation efficiency is high, the sedimentation effect is good, and the application value is improved.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to a domestic sewage sedimentation device. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for drainage or reuse. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses, etc.). The organic matter present in domestic sewage is...
