Description

Technical Field

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

[0002] Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people. Among them, wastewater sedimentation is a more important part of wastewater treatment. There are various existing sedimentation methods, among which inclined plate sedimentation is a commonly used physical sedimentation method. It uses a set of inclined plates to settle wastewater. Its sedimentation effect is related to the number of inclined plates. Moreover, the sedimentation efficiency can be improved by having multiple sets of inclined plates with different inclination directions. However, when rinsing the inclined plates, high-pressure water pipes are usually used to rinse the top of the inclined plate set, which cannot directly impact the surface of multiple inclined plates, resulting in poor cleaning effect. Utility Model Content

[0003] The purpose of this invention is to provide a wastewater sedimentation device to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A wastewater sedimentation device includes a lower annular cavity shell and an upper annular cavity shell. An assembly ring is fixedly fitted onto the top outer side of the upper annular cavity shell. The bottom of the upper annular cavity shell is inserted into the annular cavity of the assembly ring and pressed against the top annular edge of the lower annular cavity shell. A first inclined plate assembly is fixedly installed inside the lower annular cavity shell. A second inclined plate assembly, symmetrical to the first inclined plate assembly, is installed inside the upper annular cavity shell. A bottom hopper shell wall is installed at the bottom annular edge of the lower annular cavity shell. An upper shell lug is fixedly installed on the outer side of the upper annular cavity shell. A splitting and merging cylinder is installed at the bottom of the upper shell lug. The cylinder body of the splitting and merging cylinder is fixedly installed inside the lower annular cavity shell by a cylinder body frame.

[0006] Furthermore, a drain valve is installed at the bottom opening of the hopper shell.

[0007] Furthermore, the bottom of the outer wall of the upper annular cavity shell is provided with a sealing ring groove, a sealing ring is installed in the sealing ring groove, and a downward pressing cone ring surface is provided on the outer bottom of the sealing ring.

[0008] Furthermore, a filter layer is installed inside the upper annular cavity shell above the first inclined plate group.

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figure 1-3 As shown, a wastewater sedimentation device consists of a lower annular cavity shell 1 and an upper annular cavity shell 2;

[0019] An assembly ring 8 is fixedly fitted on the top of the outer side of the upper annular cavity shell 1. The bottom of the upper annular cavity 2 is inserted into the annular cavity of the assembly ring 8 and pressed onto the top ring edge of the lower annular cavity shell 1, so as to realize the quick assembly and separation of the two and facilitate separate rinsing.

[0020] The lower annular cavity shell 1 is fixedly installed with a first inclined plate group 4, and the upper annular cavity 2 is installed with a second inclined plate group 5 that is symmetrical to the first inclined plate group 4. Both the first inclined plate group 4 and the second inclined plate group 5 are composed of several parallel inclined plates. The adjacent inclined plates are in a side V shape to improve the filtration effect of the inclined plates.

[0021] A bottom hopper shell wall 3 is installed at the bottom ring edge of the lower annular cavity shell 1 to collect sediment. An upper shell lug 6 is fixedly installed on the outside of the upper annular cavity shell 2. A split-and-combination cylinder 7 is installed at the bottom of the upper shell lug 6. The cylinder body of the split-and-combination cylinder 7 is fixedly installed inside the lower annular cavity shell 1 through the cylinder body frame 10. By extending and retracting the split-and-combination cylinder 7, the lower annular cavity shell 1 and the upper annular cavity shell 2 can be separated and assembled, which facilitates the direct rinsing of the internal V-shaped inclined plate.

[0022] like Figure 1-3 As shown, this utility model also discloses the following more optimized specific structures:

[0023] A drain valve 15 is installed at the bottom opening of the hopper shell 3 for cleaning and discharging sediment.

[0024] The bottom of the outer wall of the upper annular cavity shell 2 is provided with a sealing ring groove, and a sealing ring 18 is installed in the sealing ring groove. The bottom of the outer side of the sealing ring 18 is provided with a downward pressure cone ring surface 17, which facilitates the bottom of the lower annular cavity shell 1 and the upper annular cavity shell 2 to enter the assembly ring 8 when they are assembled.

[0025] A filter layer 16 is installed inside the upper annular cavity shell 2 above the first inclined plate group 4.

[0026] The bottom of the bucket shell wall 3 is supported by a support leg 9, and the bottom of the split cylinder 7 is supported by a cylinder bearing seat 11, which is fixed to the support leg 9.

[0027] An inlet pipe 12 is installed on the upper annular shell 1, and a drain pipe 14 is installed on the top side of the upper annular shell 2. Flanges 13 are installed on the ends of the drain pipe 14 and the inlet pipe 12.

[0028] like Figure 1-3 The wastewater sedimentation device shown enters the wastewater through the inlet pipe 12. After passing through two sets of first inclined plate group 4 and second inclined plate group 5 with different directions, the wastewater is discharged from the outlet pipe 14 through the filter layer 16, resulting in a better sedimentation effect.

[0029] When cleaning is required, the drain valve 15 is opened to drain the sewage, and then the first inclined plate group 4 is directly rinsed from the top of the upper annular cavity shell 2. However, the impact force cannot impact the second inclined plate group 5. Therefore, the split cylinder 7 is activated so that the lower annular cavity shell 1 and the upper annular cavity shell 2 can be directly cleaned by the rinsing device. The cleaning is convenient and clean. After cleaning, the two are put back together for use.

[0030] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
