Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sedimentation device for wastewater treatment. Background Technology

[0002] Wastewater treatment can effectively reduce water pollution and protect the ecological balance of aquatic bodies. Untreated wastewater contains a large number of harmful substances, such as heavy metals, pathogenic microorganisms, and organic matter. Direct discharge of such wastewater can damage aquatic ecosystems, leading to eutrophication and affecting the survival of aquatic organisms. However, in existing wastewater treatment sedimentation devices, silt and suspended particles are often mixed together during sedimentation, resulting in unsatisfactory settling of suspended particles. Even after sedimentation, a small amount of suspended particles remain in the water, affecting the overall wastewater treatment effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sedimentation device for sewage treatment.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A sedimentation device for wastewater treatment includes a tank, a first partition, a second partition, a wastewater inlet pipe, a wastewater outlet pipe, an agitator, and an auger. The tank is divided into a first sedimentation zone and a second sedimentation zone by the first partition. The first sedimentation zone and the second sedimentation zone are connected through a first hole. The wastewater inlet pipe is connected to the first sedimentation zone. A baffle assembly is fixedly connected within the first sedimentation zone. The agitator is located on the side closer to the first sedimentation zone. The wastewater outlet pipe is connected to the side farther from the second sedimentation zone. The agitator and the wastewater outlet pipe are separated by the second partition. A second hole is opened in the middle of the second partition. The first sedimentation zone and the second sedimentation zone are connected to the auger through a pipe. A feed pipe is connected to the upper end of the second sedimentation zone.

[0006] Furthermore, the end of the sewage inlet pipe that extends into the first sedimentation zone is a bent pipe with its opening vertically downward.

[0007] Furthermore, the baffle assembly includes several upper baffles and several lower baffles; the upper baffles and lower baffles are arranged obliquely and parallel to each other with the left side higher than the right side.

[0008] Furthermore, the stirring unit includes a motor located on the housing above the second sedimentation zone, a rotating shaft fixedly connected to the output end of the motor and located within the second sedimentation zone, and an inclined stirring rod fixedly connected to the rotating shaft.

[0009] Furthermore, a first hopper is provided at the lower end of the first sedimentation zone; a second hopper is provided at the lower end of the second sedimentation zone.

[0010] Furthermore, the vertical cross-sections of the first and second hoppers are conical.

[0011] Furthermore, the sewage outlet pipe is a vertically downward curved pipe at one end located in the second sedimentation zone; a cap is fixedly connected to the end of the sewage outlet pipe; and six groove-shaped holes for water discharge are opened on the vertical section of the curved pipe.

[0012] The beneficial effects of this utility model are:

[0013] (1) The baffle assembly set in the first sedimentation zone can settle the silt in the sewage flowing in through the sewage inlet pipe; the sewage with silt removed flows into the second sedimentation zone through the first hole; flocculant is added through the feed pipe and the agitator accelerates the agitation so that the suspended particles settle quickly; the second baffle can ensure that the water flow in the outflowing sewage area is not agitated, effectively ensuring that no sediment flows out; the cap body can effectively prevent a small amount of sediment from flowing out; the screw conveyor 7 can facilitate the discharge of sediment in the first hopper and the second hopper.

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Reference Figure 1-2As shown, a sedimentation device for wastewater treatment includes a housing 1, a first partition 2, a second partition 3, a wastewater inlet pipe 4, a wastewater outlet pipe 5, an agitator 6, and an auger 7. The housing 1 is divided into a first sedimentation zone 8 and a second sedimentation zone 9 by the first partition 2. The first sedimentation zone 8 and the second sedimentation zone 9 are connected by a first hole 101. The wastewater inlet pipe 4 is connected to the first sedimentation zone 8. A baffle assembly 81 is fixedly connected inside the first sedimentation zone 8. The agitator 6 is located on the side close to the first sedimentation zone 8. The wastewater outlet pipe 5 is connected to the side away from the second sedimentation zone 9. The agitator 6 and the wastewater outlet pipe 5 are separated by the second partition 3. A second hole 31 is opened in the middle of the second partition 3. The first sedimentation zone 8 and the second sedimentation zone 9 are connected to the auger 7 by a pipe. A feed pipe 10 is connected to the upper end of the second sedimentation zone 9.

[0022] Specifically, in order to facilitate better sedimentation of sewage, the sewage inlet pipe 4 extends into the first sedimentation zone 8 with one end bent and the opening vertically downward, which can facilitate the sediment to settle as quickly as possible.

[0023] Specifically, the baffle assembly 81 includes several upper baffles 811 and several lower baffles 812; the upper baffles 811 and lower baffles 812 are arranged obliquely and parallelly with the left side higher than the right side.

The motor 61 can provide driving force to the rotating shaft 62 to drive the agitator 63 to rotate; the agitator 63 can accelerate the combination and sedimentation of flocculant and suspended particles.

[0025] Specifically, to facilitate the accumulation of sediment, a first hopper 82 is provided at the lower end of the first sedimentation zone 8; a second hopper 91 is provided at the lower end of the second sedimentation zone 9. The first hopper 82 and the second hopper 91 have a conical vertical cross-section.

The cap 51 can effectively prevent a small amount of sediment from flowing out; the groove-shaped holes 52 are used for sewage to enter the sewage outlet pipe 5.
