Description

Technical Field

[0001] The utility model relates to a sewage treatment device, in particular to a high-efficiency and environmentally friendly sewage sedimentation tank. Background Art

[0002] Sedimentation tanks are commonly used to treat sewage or wastewater where suspended solids are removed by gravity settling.

[0003] Before discharging sewage, it is necessary to close the water inlet valve to stop the wastewater from flowing into the sedimentation tank and open the sewage valve at the bottom of the sedimentation tank to discharge the sludge and wastewater deposited at the bottom. The opening of the sewage valve can be adjusted as needed to control the sewage discharge speed.

[0004] However, during the sewage discharge process, the bottom sedimentation is prone to cause blockage, and more water flow is needed to mix the sediment at the bottom to make it flow, which in turn reduces the sewage discharge efficiency. Utility Model Content

[0005] The utility model provides a high-efficiency and environmentally friendly sewage sedimentation tank, which can effectively solve the problem.

[0006] The utility model is achieved in this way:

[0007] A high-efficiency and environmentally friendly sewage sedimentation tank, whose structure includes: a dosing bin, a stirrer is provided on the top of the dosing bin, the dosing bin is connected to a diversion tank through a sedimentation tank, a sedimentation seat is installed at the bottom of the sedimentation tank, the sedimentation seat includes a protective outer cavity installed at the bottom of the sedimentation tank, a support seat is provided at the bottom of the protective outer cavity, and the support seat and the turntable are nested with each other, a support partition is also installed on the top of the protective outer cavity, a through hole is provided in the middle of the support partition and is nested with a turntable, the support seat is communicated with a sewage pipe, and the driver of the sedimentation seat 1 drives the turntable to rotate through a gear box.

[0008] As a further improvement, the turntable includes a bucket body, a toothed disc is mounted on the top of the bucket body, and the bucket body is meshed with the outer teeth of the gear box through the toothed disc, and a raised socket is provided at the bottom of the bucket body.

[0009] As a further improvement, the bucket body is a bucket-shaped structure, the side with a larger opening is welded and fixed to the toothed disc, and the side with a smaller opening is connected to the sleeve.

[0010] As a further improvement, a cross-arranged partition plate is also provided in the middle of the sleeve.

[0011] As a further improvement, the inner wall of the bucket body is provided with two or more guide plates, and the guide plates are evenly distributed along the circumference.

[0012] As a further improvement, the bottom of the sedimentation tank is provided with a protrusion which is nested with the inner wall of the bucket.

[0013] As a further improvement, the sedimentation seat is provided with two fixed at the bottom of the sedimentation tank.

[0014] The beneficial effects of the utility model are as follows: the improved device drives the turntable at the bottom to rotate through the gear box. The rotation of the turntable will cause the sediment falling on the surface to separate from the inner wall of the turntable. At the same time, compared with the direct stirring method using a scraper, the resistance is smaller. During the rotation, the sediment is gradually mixed with the liquid. During the discharge, the pores generated at the bottom increase the collapse speed of the sediment when it flows out, thereby reducing the blockage in the sewage pipe. In addition, a partition plate is arranged at the bottom opening of the bucket body to stir the liquid to further increase the liquid flow rate, which is more efficient when discharging sewage.

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0025] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] However, during the existing sewage discharge process, the bottom sedimentation is prone to cause blockage, and more water flow is needed to mix the sediment at the bottom to make it flow, which leads to a decrease in sewage discharge efficiency. Therefore, in order to solve the above problems, this case proposes the following technical solutions:

[0027] Reference Figure 1 to Figure 4 As shown, a high-efficiency and environmentally friendly sewage sedimentation tank comprises: a dosing bin 2, a stirrer 3 is provided on the top of the dosing bin 2, the dosing bin 2 is connected to the diversion tank 5 through the sedimentation tank 4, a sedimentation seat 1 is installed at the bottom of the sedimentation tank 4, the sedimentation seat 1 comprises a protective outer cavity 15 installed at the bottom of the sedimentation tank 4, a support seat 14 is provided at the bottom of the protective outer cavity 15, and the support seat 14 and the turntable 13 are nested with each other, and a support baffle 17 is also installed on the top of the protective outer cavity 15, a through hole is provided in the middle of the support baffle 17 and is nested with the turntable 13, the support seat 14 is communicated with the sewage pipe 16, and the driver 11 of the sedimentation seat 1 drives the turntable 13 to rotate through the gear box 12.

[0028] The main structure of the device includes a dosing bin 2, which is used to add flocculants and is stirred by a stirrer 3 on the top. After the sewage enters the dosing bin 2, it combines with the flocculant and then flows into the sedimentation tank 4 for sedimentation treatment. The clear water after sedimentation flows from the top into the diversion tank 5 and is discharged through a pipeline for secondary treatment.

[0029] A sedimentation seat 1 is installed at the bottom of the sedimentation tank 4, and the sedimentation seat 1 is used for carrying and stirring the sediment. After the sediment is precipitated in the inner cavity of the sedimentation tank 4, it falls into the bucket 132 of the turntable 13 and gradually accumulates. The support partition 17 and the protruding interface at the bottom of the sedimentation tank 4 are provided with a seal, and the connecting part of the turntable 13 and the support seat 14 is also provided with a sealing ring, so that when the driver 11 drives the gear box 12 to drive the turntable 13 to rotate, there will be no water leakage. In order to avoid sewage leakage caused by aging of the sealing ring, the device is provided with a protective outer cavity 15 on the outside of the turntable 13 for further isolation. The protective outer cavity 15 is provided with a sewage pipe to the outside. When water leakage occurs, liquid will appear in the pipe leading out of the protective outer cavity 15 and it can be replaced in time. At the same time, it can also continue to work while waiting for maintenance.

[0030] The support seat 14 at the bottom is connected to the sewage pipe 16. When sewage needs to be discharged, the turntable 13 is driven to rotate, and the sediment is mixed with the liquid and flows into the sewage pipe 16 through the sedimentation tank 4. When the pipe valve connected to the sewage pipe 16 is opened, the mixed liquid will be discharged from the sewage pipe 16 to realize sewage discharge.

[0031] The turntable 13 is nested in the surface of the supporting partition 17, and the bucket body 132 is meshed with the outer teeth of the gear box 12 through the toothed disc 131. During the rotation, the guide plate 133 inside the bucket body 132 will push the sediment that has been attached to the surface of the bucket body 132 to recombine with the liquid, and a partition plate 135 is set at the sleeve 134 at the bottom of the bucket body 132. During the rotation, the partition plate 135 guides the liquid to speed up the flow rate, thereby making the sediment at the bottom discharge more smoothly.

[0032] The improved device drives the turntable 13 at the bottom to rotate through the gear box 12. The rotation of the turntable 13 will cause the sediment falling on the surface to separate from the inner wall of the turntable 13. At the same time, compared with the direct stirring method using a scraper, the resistance is smaller. During the rotation process, the sediment is gradually mixed with the liquid. During the discharge, the pores generated at the bottom increase the collapse speed of the sediment when flowing out, thereby reducing the blockage in the sewage pipe 16. In addition, a partition plate 135 is set at the bottom opening of the bucket body 132 to stir the liquid to further increase the liquid flow rate, which is more efficient when discharging sewage.

[0033] The above only describes the basic principles and preferred implementations of the present utility model. Those skilled in the art can make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of the present utility model.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
