Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment with sewage treatment agents, and in particular relates to a sewage treatment device. Background Art

[0002] Sewage is wastewater generated by urban life and industrial production. Sewage contains a large amount of pollutants. If it is directly discharged into the natural ecological environment, it will not only seriously pollute the ecological environment, but also easily cause pollution of drinking water resources.

[0003] Therefore, sewage needs to be treated for environmental reasons before it can be discharged without causing pollution. Environmental treatment methods mainly include physical treatment such as adsorption and filtration, chemical treatment such as treatment with degradation agents and sedimentation agents, and ecological treatment such as microbial degradation.

[0004] Among them, degradation treatment in chemical treatment is one of the most important steps in sewage treatment. The specific method is to pump the sewage into a sewage pool and add flocculants for static sedimentation treatment. However, because flocculation and sedimentation are static sedimentation treatment processes, the existing technology directly pumps the flocculants into the sewage pool. Due to static flocculation and sedimentation, the flocculants cannot be quickly dispersed into the sewage system. This causes the flocculation and sedimentation process to take too long. Moreover, since flocculants and other sedimentation agents cannot be quickly dispersed into the sewage, it is very easy to cause the local concentration of flocculants in the sewage pool to be too high after the material is pumped into the sewage pool, further resulting in a poor flocculation and sedimentation effect.

[0005] Therefore, for static flocculation and sedimentation, how to quickly and efficiently disperse the flocculant into the static sewage is very important for improving the sedimentation effect of sewage and shortening the sedimentation time. Utility Model Content

[0006] Based on the above background, the purpose of the present invention is to provide a sewage treatment device.

[0007] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0008] A sewage treatment device includes an annular rolling mechanism that rolls on an outlet of a sewage treatment tank, wherein the annular rolling mechanism includes a cross beam that spans across two sides of the outlet of the sewage treatment tank;

[0009] Driving roller assemblies are respectively installed at both ends of the cross beam;

[0010] Both sides of the cross beam are respectively equipped with a spraying mechanism, the spraying mechanism includes a pumping pipe, the bottom of the pumping pipe is connected to a plurality of spraying pipes, the side wall of the spraying pipe is connected to a plurality of spraying and dispersing pipes, and the spraying and dispersing pipes are provided with a plurality of spraying holes;

[0011] The discharge end of the spray pipe is fixedly connected to a dispersion plate, and a plurality of spray holes are opened on the dispersion plate;

[0012] The dispersion plate is fixedly connected to a diverter plate;

[0013] When the annular rolling mechanism rolls on the outlet of the sewage treatment pool, the spraying mechanism sprays the sewage treatment agent into the sewage pool, and the diverter plate stirs and disperses the sewage treatment agent.

[0014] Preferably, a central mounting hole is provided in the central portion of the cross beam;

[0015] The sewage treatment device is fixedly connected to a central limiting column which is rotatably connected to the central mounting hole. During the rolling process of the driving roller assembly, the roller assembly rolls in a circular shape with the central limiting column as the center point.

[0016] Preferably, the spray dispersion pipe is U-shaped.

[0017] Preferably, an oblique connecting rod is fixedly connected to the top of the diverter plate, and the oblique connecting rod is fixedly connected to the diverter plate.

[0018] Preferably, the spraying pipe is arranged at an angle.

[0024] The utility model has the following beneficial effects:

[0025] 1 During the working process, the roller assembly is first driven to roll on the pool mouth of the sewage pool. During the rolling process, since the center part of the cross beam is limited on the center limit column, the rolling method can only be circular rolling with the center limit column as the center point.

[0026] As the drive roller assembly and crossbeam rotate, the spray pipe sprays the sedimentation agent from the spray dispersion pipe. Because the spray dispersion pipe has multiple spray holes, a large amount of chemical sedimentation agent is dispersed and sprayed from the spray dispersion pipe during the spraying process and distributed into the sewage treatment tank. The continuous circular movement of the crossbeam and spray dispersion pipe causes a large amount of treatment agent to be dispersed and sprayed around the circumference of the sewage tank, thus achieving uniform dispersion of the chemical during the sedimentation process.

[0027] 2. During the working process, when the entire device moves in a circular motion, the diverter plate continuously stirs the flocculant just sprayed into the sewage pool (the flocculant is not fully dispersed at this time), and further improves the dispersion of the sedimentation agent during the stirring process.

[0037] Example 1

[0038] like Figure 1-4 As shown, a sewage treatment device includes an annular rolling mechanism that rolls on the outlet of the sewage treatment pool. By rolling around the outlet of the sewage treatment pool, flocculants and other sedimentation agents are continuously pumped into the static sewage pool, thereby achieving full dispersion of the sedimentation agents to increase the flocculation and sedimentation effect.

[0039] The specific structure of the annular rolling mechanism is as follows:

[0040] The circular rolling mechanism includes a crossbeam 1 that spans across the sewage treatment tank outlet. Drive roller assemblies are installed at the front and rear ends of the crossbeam 1. The drive roller assemblies enable the entire device to roll in a circular motion on the sewage tank outlet.

[0041] At the same time, the two sides of the cross beam 1 are respectively equipped with a spraying mechanism 3 (the specific layout is: the spraying mechanism 3 on both sides of the cross beam 1 is symmetrically arranged front to back with the center point of the cross beam 1 as the symmetrical point), and the spraying mechanism includes a pumping pipe 31, and the bottom of the pumping pipe 31 is connected to a number of spraying pipes 34 (the spraying pipe 34 is arranged tilted downward), and the side wall of the spraying pipe 34 is connected to a number of U-shaped spray dispersion pipes 32 (the two ends of the spray dispersion pipe 32 are fixedly connected to the spray pipe 34 by welding), and a number of spray holes 321 are opened on the spray dispersion pipe 32.

[0042] At the same time, according to the existing pumping method, the feed end of the pumping pipe 31 is connected to a pumping hose (not shown in the figure) through a flange; the pumping hose pumps the sewage treatment agent into the spraying pipe 34.

[0043] A central mounting hole 11 is provided at the center of the cross beam 1. According to the existing circumferential motion method, a central limiting column (not shown in the figure) is fixedly connected to the central mounting hole 11 in the sewage treatment plant. During the rolling process of the driving roller assembly, the central limiting column is used as the center point and the roller assembly rolls in a circular manner.

[0044] During operation, the roller assembly is first driven to roll on the mouth of the sewage pool. During the rolling process, since the center part of the cross-beam 1 is limited on the center limit column, the rolling method can only be circular rolling with the center limit column as the center point.

[0045] As the drive roller assembly and crossbeam 1 rotate, spray pipe 34 sprays the chemical settler from spray dispersion pipe 32. Because spray dispersion pipe 32 has multiple spray holes 321, a large amount of chemical settler is dispersed and sprayed from spray dispersion pipe 32 during the spraying process and distributed into the sewage treatment tank. The continuous circular motion of crossbeam 1 and spray dispersion pipe 32 allows a large amount of treatment agent to be dispersed and sprayed around the circumference of the sewage tank, thus achieving uniform dispersion of the chemical during the sedimentation process.

[0046] Example 2

[0047] like Figure 1-4 As shown, in this embodiment, based on the structure of embodiment 1, the discharge end of the spray pipe 34 is fixedly connected to a dispersion plate 35, and a plurality of spray holes 351 are opened on the dispersion plate 35; the chemical agent is further sprayed in a spraying manner through the dispersion plate 35-spray holes 351.

[0048] At the same time, the dispersing plate 35 is fixedly connected to the diverter plate 33 ; specifically, the top of the diverter plate 33 is fixedly connected to an oblique connecting rod, which is fixedly connected to the diverter plate 33 .

[0049] During operation, when the entire device moves in a circular motion, the diverter plate 33 continuously stirs the flocculant just sprayed into the sewage pool (the flocculant is not fully dispersed at this time), and further improves the dispersion of the sedimentation agent during the stirring process.

[0050] Example 3

[0051] like Figure 1-4 As shown, in this embodiment, based on the structure of embodiment 2, the above-mentioned driving roller assembly (the rolling forward direction of the driving roller assembly on one side is opposite to that of the driving roller assembly on the other side) includes a roller frame 21, and a roller 23 is rotatably connected inside the roller frame 21 (the axle on the roller 23 is rotatably connected to the roller 23 frame 21 in the same manner as in the existing method), and a roller motor 22 for driving the roller 23 to rotate is installed on the roller 23 frame 21 (the motor is fixedly installed on the roller 23 frame 21 in the same manner as in the existing method).

[0052] The ends of the cross beam 1 at both ends are integrally formed with mounting portions vertically arranged upward, and the mounting portions are fastened to the roller 23 frame 21 by bolts.

[0053] During operation, driven by the motor, the roller 23 rotates and rolls at the pool mouth. Since the center position of the crossbeam 1 is limited by the limit column, with the cooperation of the driving roller 23 components on both sides, it can achieve circumferential rolling on the pool mouth of the sewage pool, and continuously spray chemicals during the circumferential rolling process.

[0054] 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.
