Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to a dosing device for sewage treatment. Background Art

[0002] Wastewater treatment refers to the process of purifying wastewater so that it meets the water quality requirements for discharge into a certain water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. When carrying out sewage treatment operations, flocculants are generally added to the sewage to flocculate various substances in the sewage in order to achieve the purpose of purifying the sewage.

[0003] After searching, the existing patent (Announcement No.: CN219279531U) discloses a dosing device for sewage treatment. During use, the drug liquid is added into the drug liquid tank, and the agitator rotates to make the opening of the second through hole face the opening of the first through hole, so that the drug liquid in the drug liquid tank enters the pipe groove, and the drug entering the pipe groove is sprayed into the sewage through the nozzle. The sewage sprayed with the drug liquid is stirred by the agitator, so that the drug liquid can penetrate into the sewage, so that the drug liquid and the sewage are fully integrated, and the treatment effect of the drug liquid on the sewage is improved. However, the inventor found that the prior art has the following problems in the process of realizing the utility model: the above-mentioned dosing device lacks the function of cleaning the flocculants precipitated in the sewage. When the agent is added into the sewage to make the substances in the sewage flocculate and precipitate, if the flocculants are not discharged in time, it will affect the subsequent contact and reaction between the agent and the substances in the sewage, thereby reducing the efficiency of sewage treatment.

[0004] In view of this, the utility model proposes a sewage treatment dosing device with a cleaning function. Utility Model Content

[0024] During use, the sewage collected from the outside is discharged into the sewage treatment tank 1 through the water inlet pipe 16, and after being treated to be qualified, the water is discharged through the drain pipe 17.

[0025] A controller 26 is fixedly installed on the side of the sewage treatment tank 1, and the controller 26 is electrically connected to an external power control system.

[0026] Two mounting frames 2 are arranged across the top of the sewage treatment tank 1, a reciprocating screw 3 is rotatably connected between the two mounting frames 2, and a first servo motor 4 for driving the reciprocating screw 3 to rotate is fixedly mounted on the surface of the right mounting frame 2, and a transverse seat 5 is threadedly connected to the surface of the reciprocating screw 3.

[0027] Two limiting slide bars 18 are fixedly installed between the two mounting frames 2 , and the transverse seat 5 is slidably connected to the surfaces of the limiting slide bars 18 .

[0028] By providing the limiting slide bar 18 , the moving path of the transverse seat 5 can be limited to prevent the transverse seat 5 from flipping over.

[0029] An extension rod 6 is provided at the bottom end of the transverse seat 5, and a collecting rack 7 is fixedly installed at the bottom end of the extension rod 6. The collecting rack 7 is adapted to the inner cavity shape of the sewage treatment tank 1, and a movable gap is reserved between the bottom side of the collecting rack 7 and the inner bottom wall of the sewage treatment tank 1. A dosing tube 8 is embedded in the surface of the collecting rack 7, and the liquid inlet end of the dosing tube 8 is connected to the external drug input pipe. The left and right ends of the collecting rack 7 are interconnected, and two filter mesh plates 9 are symmetrically embedded in the inner wall of the collecting rack 7. The drug outlet end of the dosing tube 8 is located between the two filter mesh plates 9, and the left and right ends of the collecting rack 7 are provided with slag collecting chambers 10 through the filter mesh plates 9.

[0030] During use of the utility model, sewage treatment agents are added into the sewage treatment pool 1 through the dosing pipe 8. After the sewage contacts with the agents, floccules are generated. The reciprocating screw 3 is driven to rotate by the first servo motor 4, which can drive the collecting frame 7 to move left and right. The sewage is filtered by the filter screen 9, and a large amount of floccules can be collected in the slag collecting chamber 10.

[0031] The transverse seat 5 is movably connected to the extension rod 6, and a turnover and fluff-clearing component is arranged between the transverse seat 5 and the extension rod 6.

[0032] The flipping and deflocculating assembly includes a flipping shaft 11 rotatably connected to the bottom side of the transverse seat 5, the extension rod 6 is fixedly mounted on the surface of the flipping shaft 11, and a flip box 12 is fixedly mounted on the bottom side of the transverse seat 5, the flipping shaft 11 is rotatably connected to the flip box 12, a second servo motor 13 is fixedly mounted on the surface of the flip box 12, the output shaft of the second servo motor 13 extends to the interior of the flip box 12 and is fixedly mounted with a worm 14, a worm wheel 15 is fixedly mounted on the surface of the flipping shaft 11, and the worm 14 is meshed with the worm wheel 15.

Since the influence of the flocculants on the diffusion of the agent is reduced during the medication process, the efficiency of sewage treatment can be improved.

[0034] It is worth noting that, since there is a movable gap between the bottom side of the collecting rack 7 and the inner bottom wall of the sewage treatment tank 1, the flocculants in the sewage cannot be fully collected and can only collect the flocculants precipitated from the upper layer of the sewage during the dosing process.

[0035] A residual material discharge port 19 is provided between the two filter screen plates 9 at the bottom end of the collecting frame 7 .

[0036] During the sewage treatment process, part of the floccules are generated between the two filter screen plates 9 . These floccules can be cleaned through the residual material discharge port 19 to maintain the permeability of the filter screen plates 9 .

[0037] Two side plates 20 are symmetrically fixedly installed on the inner wall of the collecting frame 7. The two side plates 20 are located between the two filter screens 9. The surfaces of the two side plates 20 are rotatably connected to a delivery pipe 21. The surface of the delivery pipe 21 is rotatably connected to a jacket 22 through a sealed bearing.

The liquid outlet 25 is connected to the liquid inlet 23 through the inner cavity of the delivery pipe 21 .

[0039] There are a plurality of spiral blades 24 , which are arranged in a circular array at the end of the delivery pipe 21 .

[0040] Furthermore, during the dosing process, by providing a delivery pipe 21, a jacket 22 and a spiral blade 24, during the movement of the collecting rack 7, the contact between the sewage and the spiral blade 24 can drive the delivery pipe 21 to rotate, and the medicine enters the jacket 22 and the inner wall of the delivery pipe 21 from the liquid inlet 23, and then is discharged from the liquid outlet 25. Since the spiral blade 24 continues to rotate, the position of the liquid outlet 25 and the medicine discharge can be continuously adjusted, thereby improving the uniformity of the medicine delivery and ensuring the efficiency of sewage treatment.

[0041] Finally, it should be noted that the drawings of the embodiments disclosed in the present invention only involve structures related to the embodiments disclosed in the present invention, and other structures may refer to the usual design. In the absence of conflict, the same embodiment and different embodiments of the present invention may be combined with each other.
