Description

Technical Field

[0001] The utility model belongs to the technical field of sewage flocculation treatment, in particular to a sewage flocculation sedimentation device. Background Art

[0002] Sewage, especially wastewater generated by industrial production, contains a large amount of highly polluting substances, including organic matter.

[0003] Organic matter in wastewater is flocculated and settled to produce organic sludge. This organic sludge undergoes subsequent environmentally friendly treatment, such as heat treatment, to produce recycled activated carbon for industrial production. Flocculation and sedimentation significantly reduce the organic matter content in wastewater, improving its cleanliness and clarity.

[0004] During the flocculation and sedimentation process, flocculants are added to the sewage. The more conventional way of adding materials is to add materials from the pool mouth. However, after adding materials from the pool mouth, a large amount of settled materials are easily suspended in the sewage (it takes a long time for the flocculant to fully react with the sewage at the bottom of the sewage pool, that is, the sewage pool is severely stratified, and the upper part of the sewage settles to produce a sedimentation suspended layer, resulting in the lower sewage being unable to fully settle), resulting in the flocculant being unable to effectively act on the lower sewage.

[0005] Therefore, in the actual working process, a pipe for pumping flocculants is installed at the bottom of the sewage pool. However, as the flocculated sediment increases, the pipe for pumping flocculants is easily buried and blocked, which makes it impossible for the flocculants to be discharged from the blocked pipe position.

[0006] Although filters are installed at the discharge port of the pipeline, the flocculated sedimentation materials, especially the mud with high viscosity, are very likely to clog the filters, which still makes it impossible to effectively pump the flocculant. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a sewage flocculation and sedimentation device.

[0008] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0028] The utility model has the following beneficial effects:

[0029] 1. During operation, the flocculant is pumped from the flexible connecting pipe into the pump flocculant pipe, and then diverted to each annular diversion pipe, and then diverted to each annular spray pipe. After that, it is diverted from the annular spray pipe position and sprayed from each nozzle. This method sprays the sedimentation agent into the sewage in different directions, thereby increasing the dispersion speed of the flocculant in the sewage, thereby accelerating the flocculation sedimentation time and the flocculation effect.

[0030] 2. During operation, the air inlet nozzle is connected to the air pump via a flexible hose. When the air pump is turned on, the volume of the float increases, and so does the buoyancy. This increased buoyancy allows the entire device to move upward and free itself from the buried sludge, resolving the technical issue of severe blockage in the pumping line when pumping settlers from the bottom of the sewage pool. This increased buoyancy also shifts the flocculant spray position, allowing the device to be sprayed at varying heights within the sewage. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Example 1

[0042] like Figure 1-5 As shown, a sewage flocculation and sedimentation device includes a flocculant discharge mechanism, which includes a plurality of flocculant discharge components spaced apart from each other. The flocculant discharge components each include an annular diverter pipe 31, and the annular diverter pipe 31 is connected to a plurality of spraying components 33 for spraying flocculants.

[0043] Specifically, the spraying component 33 includes a straight diversion pipe 331 connected to the annular diversion pipe 31. The straight diversion pipe 331 is connected to a plurality of annular spraying pipes 332. (The annular spraying pipes 332 are connected to the straight diversion pipe 331 via a diameter pipe 334 at a diameter position, i.e., the ends of the diameter pipe 344 are connected to the annular spraying pipe 332 and the straight diversion pipe 331, respectively.) The annular spraying pipe 332 is connected to a plurality of nozzles 333. The nozzles 333 are conventional nozzles 333 disclosed in the prior art.

[0044] The annular diverter pipes 31 are connected to each other via a plurality of connecting pipe structures. Specifically, the connecting pipe structure includes a connecting pipe 35 , which is connected to the annular diverter pipe 31 via a plurality of side pipes. The connecting pipe 35 is connected to a pump flocculant pipe 351 .

[0045] According to the conventional method disclosed in the prior art, the pump flocculant tube is connected to the external pump flocculant pipeline through the soft connecting tube, so that during the working process, the flocculant is pumped into the pump flocculant tube 351 from the soft connecting tube, and is diverted to each annular diversion tube 31, and then diverted to each annular spraying pipe 332, and then diverted from the position of the annular spraying pipe 332 to be sprayed from each nozzle 333.

[0046] The purpose of this method is to spray the sedimentation agent in the sewage in different directions, thereby increasing the dispersion speed of the flocculant in the sewage and accelerating the flocculation sedimentation time and flocculation effect.

[0047] Under the above structure, the flocculant is sprayed in a radial form and a large amount of sedimentation materials can be settled in a short time.

[0048] Example 2

[0049] like Figure 1-5 As shown, this embodiment builds on the structure of Example 1. To prevent settled sludge from burying the flocculant discharge mechanism and potentially clogging spray points, such as nozzle 333, on the flocculant discharge mechanism, the sewage flocculation and sedimentation device further includes a float mechanism for raising and lowering the flocculant discharge mechanism. This float mechanism allows the entire device to be raised after a period of flocculation, freeing it from the sludge. Specifically, the float mechanism includes an adjustable float 21, with a pull rod 22 fixedly connected to its bottom.

[0050] Specifically, the diameter portion of the annular diverter pipe 31 is fixedly connected to the inner connecting seat 32, and a through connecting rod is fixedly connected between the inner connecting seats 32. The through connecting rod connects all the annular diverter pipes 31 into one.

[0051] At the same time, the top of the inner connecting seat 32 is fixedly connected to two pulling rods 22 spaced apart on the left and right sides, and fixedly connected to the top position of the inner connecting seat 32.

[0052] According to the existing method, the top of the float 21 (the float 21 is limited to rubber material) is connected to the air inlet nozzle 211, and the air inlet nozzle 211 is connected to the air pump.

[0053] During operation, according to the existing method, the air inlet nozzle 211 is connected to the air pump through a hose. When the air pump is turned on, the volume of the float 21 increases, and the buoyancy increases. At this time, after the buoyancy increases, the entire device moves upward and breaks free from the shackles of the buried mud.

[0054] As the buoyancy increases, the spraying position of the flocculant also changes, and this method can further achieve the pump spraying of the sedimentation agent at different heights in the sewage.

[0055] Example 3

[0056] like Figure 1-5 As shown, based on the structure of Example 2, this embodiment further includes a retaining cage mechanism to prevent the settled sludge from burying the sewage flocculation and sedimentation device.

[0057] Specifically, the flocculant discharging mechanism is located in the retaining cage mechanism, and the retaining cage mechanism is used to isolate the flocculated and settled dirt.

[0058] The cage mechanism includes a base 1 fixedly mounted at the bottom of the flocculation tank. A mesh cage 11 is fixedly connected to the top of the base 1. Mesh cage 11 is a cylindrical metal mesh cage known in the prior art. Mesh cage 11 is of a certain height and covers the flocculant discharge mechanism to prevent it from being covered or buried by settled sludge.

[0059] At the same time, a central guide rail rod 34 is slidably connected to the central portion of the inner connecting seat 32 , and the central guide rail rod 34 is fixedly connected to the base 1 .

[0060] The pulling rod 22 passes through the top of the mesh cage 11 cover, and the pulling rod 22 is slidably connected to the mesh cage 11 cover (a through hole is opened on the top of the mesh cage 11 cover. Similarly, the flexible connecting pipe connected to the pump flocculant pipe passes through the top of the mesh cage 11 cover).

[0061] During the lifting process, the vertical rise is achieved by the guidance of the central guide rail rod 34, and the clogging caused by the silt is avoided. Moreover, the defect of silt clogging is further reduced due to the ability to move up and down.

[0062] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
