Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to a sewage treatment device. Background Art

[0002] Wastewater treatment is a method of separating pollutants contained in wastewater or converting them into harmless substances, thereby purifying wastewater. Wastewater chemical treatment is a wastewater treatment method that separates and removes pollutants in dissolved or colloidal states in wastewater or converts them into harmless substances through chemical reactions and mass transfer. Treatment units based on adding chemicals to produce chemical reactions include coagulation, neutralization, oxidation-reduction, etc.; treatment units based on mass transfer include extraction, stripping, air stripping, adsorption, ion exchange, electroosmosis and reverse osmosis, etc. There are wastewater neutralization treatment methods, wastewater coagulation treatment methods, wastewater chemical precipitation treatment methods, wastewater oxidation treatment methods, wastewater extraction treatment methods, etc.

[0003] After massive searches, it was found that the prior art publication number is: CN219314790U. This patent uses a layered treatment method to precipitate and sterilize sewage. When the first cavity is precipitating, the third cavity can be sterilized. The two can be carried out simultaneously without interfering with each other, which improves the sewage treatment efficiency, enhances the practicability of the equipment, and at the same time improves the use effect of the equipment.

[0004] However, the patent can only add the coagulant by manually adjusting the valve, which may cause inaccurate addition due to improper operation or too little stock, and the centralized addition of flocculants may also cause insufficient mixing of the flocculants and sewage, which will cause the tiny particles in the sewage to fail to be fully mixed with the coagulant, resulting in waste of coagulants, reduced treatment efficiency, increased costs and negative impact on the environment. Therefore, we propose a sewage treatment device. Utility Model Content

According to the setting of the reducer, after the hollow rotating tube rotates the set number of circles to fully mix the flocculant and the sewage for the first time, the brush contacts the annular electrode again, and the water pump is turned on again to continue adding the flocculant. The heating patch attached to the outer surface of the sewage treatment barrel can heat the sewage to achieve convection of the liquid in the barrel. The device can not only make the sewage and the flocculant mix more fully, but also avoid the waste of coagulant and solve the background problem.

[0026] When in use, the sewage to be treated is slowly injected into the sewage treatment barrel 14, the motor 3 is turned on, and the rotating component is started. The motor 3 will start the forward and reverse rotation of the hollow rotating tube 17 and the stirring frame 23 through gear transmission, which will ensure that the sewage and the coagulant are fully mixed. At the same time, the coagulant is injected intermittently and slowly during the injection process to avoid concentrated injection. The forward and reverse rotation of the hollow rotating tube 17 and the stirring frame 23 can improve the mixing efficiency.

[0027] The rotating assembly includes a motor 3, the output end of the motor 3 is fixedly connected to the second bevel gear 2, a rotating sleeve 10 is installed on the upper surface of the sewage treatment cylinder 14, an annular inner gear ring 28 is installed inside the rotating sleeve 10, a first bevel gear 15 is fixedly connected above the annular inner gear ring 28, the first bevel gear 15 is meshed with the second bevel gear 2, the first bevel gear 15 is meshed with the third bevel gear 4, a rotating tube 8 is rotatably installed inside the rotating sleeve 10, a first gear 22 is fixedly sleeved on the outer surface of the rotating tube 8, a second gear 29 and a third gear 27 are rotatably installed inside the rotating sleeve 10, the second gear 29 is meshed with the annular inner gear ring 28, the third gear 27 is meshed with the annular inner gear ring 28, a first gear 22 is sleeved and fixed on the outer side of the rotating tube 8, the second gear 29 is meshed with the first gear 22, and the third gear 27 is meshed with the first gear 22.

[0028] The outer annular inner gear ring 28 drives the first gear 22 to rotate in the opposite direction through the second gear 29 and the third gear 27, thereby driving the rotating tube 8 to rotate. The rotating tube 8 is fixedly connected to the hollow rotating tube 17, the hollow liquid spraying pipe 18 is fixedly connected to the hollow rotating tube 17, and the stirring frame 23 is fixedly connected to the annular inner gear ring 28, thereby achieving the effect of the hollow liquid spraying pipe 18 and the stirring frame 23 rotating in the opposite direction.

[0029] An annular electrode 26 is installed on the pump housing 7, and a rotating arm 24 is fixedly connected to the output end of the reducer 6, and a brush 25 is fixedly connected to one end of the rotating arm 24. When the device is just started, the annular electrode 26 and the brush 25 are in contact, but as the device runs, the output end of the reducer 6 drives the rotating arm 24 and the brush 25 connected thereto to rotate. After rotating a certain angle, the brush 25 is separated from the protrusion on the annular electrode 26, and the pump housing 7 is disconnected and stops working. After the output end of the reducer 6 rotates one circle, the brush 25 contacts the protrusion on the annular electrode 26 again. At this time, the circuit is connected, and the pump housing 7 continues to work, and the flocculant is added into the hollow rotating tube 17, and sprayed into the sewage treatment cylinder 14 through the hollow liquid injection pipe 18 connected thereto, thereby achieving the effect of intermittently adding flocculants.

[0031] A drain pipe 12 is installed at the inner bottom of the sewage treatment barrel 14, a filter screen 20 is installed on the top of the drain pipe 12, and an arc scraper 21 is rotatably sleeved on the outer surface of the drain pipe 12. The arc scraper 21 is fixedly connected to the stirring frame 23 through a connecting rod. The arc scraper 21 contacts the bottom of the inner surface of the sewage treatment barrel 14. When the sediment in the sewage completes sedimentation, the valve of the drain pipe 12 is opened to discharge the treated sewage from the sewage treatment barrel 14. After the sewage is discharged, the valve at the bottom of the sewage treatment barrel 14 is opened, and the motor 3 is turned on. The arc scraper 21 discharges the sediment at the bottom of the barrel from the sewage treatment barrel 14 through centrifugal force and stores it in the sewage collecting box 11.

[0032] Working principle: When in use, slowly inject the sewage to be treated into the sewage treatment barrel 14, turn on the motor 3, and start the rotating assembly. The motor 3 will start the forward and reverse rotation of the hollow rotating tube 17 and the stirring frame 23 through gear transmission. This will ensure that the sewage and the coagulant are fully mixed. At the beginning of the treatment, as needed, open the valve of the infusion pipe 5 of the pump housing 7 and start adding coagulant to the sewage. The coagulant will be sprayed into the sewage through the hollow spray pipe 18. The rotation of the stirring frame 23 will ensure that the sewage and the coagulant are fully mixed and promote the reaction. At the same time, the heating patch 19 attached to the outer surface of the sewage treatment barrel 14 heats the sewage and causes convection of the internal sewage, thereby increasing the reaction rate. The coagulated precipitate will gradually gather at the bottom of the sewage treatment barrel 14. You can regularly open the valve of the sewage collection box 11 and discharge the precipitated sewage into the sewage collection box 11 through the rotating arc scraper 21.
