Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a dosing device for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of removing pollutants (such as suspended solids, organic matter, heavy metals, pathogens, etc.) from wastewater through physical, chemical, or biological methods to meet discharge standards or recycling requirements. In the wastewater treatment process, dosing devices achieve water purification goals by accurately metering and adding chemical agents (such as coagulants, disinfectants, pH adjusters, etc.). Its core functions include pollutant removal, disinfection and sterilization, and water quality regulation.

[0003] When using the dosing device, the chemicals are stirred and mixed by a stirring paddle, and then sprayed into the sewage tank by a nozzle. However, the garbage and impurities floating on the surface of the sewage block the chemicals, making it difficult for the chemicals to mix fully with the sewage, resulting in poor sewage treatment effect. In addition, the height of the storage tank is fixed and not easy to adjust. Therefore, we propose a dosing device for sewage treatment. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Reference Figure 1-5 A dosing device for sewage treatment includes a storage tank 2. Support legs 3 are fixedly installed at the four corners of the lower surface of the storage tank 2. There are four sets of support legs 3. A stirring structure 1 is embedded in the upper surface of the storage tank 2. A liquid level sensor 4 is embedded in the upper part of the storage tank 2. A conveying structure 5 is embedded in the lower part of the storage tank 2.

[0025] Specifically, the stirring structure 1 stirs the liquid medicine inside the storage tank 2 to prevent sedimentation. The support leg 3 supports the storage tank 2, and the conveying structure 5 conveys the liquid medicine to ensure that it is fully integrated into the wastewater. The liquid level inside the storage tank 2 is monitored by the liquid level sensor 4, model TLW-136, which can monitor the liquid level inside the tank 204. When the liquid level inside the tank 204 is too low, a signal is transmitted to the control center to remind people to add liquid medicine. The entire device is controlled by external equipment and powered by an external power supply.

[0026] The stirring structure 1 includes a stirring motor 101, a first stirring rod 102, a rotating shaft 103, a second stirring rod 104, a third stirring rod 105, a liquid inlet 106, a through groove 107, and a liquid outlet 108. The output end of the stirring motor 101 is fixedly connected to the rotating shaft 103. The first stirring rod 102 is fixedly installed on the surface of the rotating shaft 103 at the top. The second stirring rod 104 is fixedly installed on the surface of the rotating shaft 103 at the middle. There are two sets of second stirring rods 104. The third stirring rod 105 is embedded and installed on the surface of the rotating shaft 103 at the bottom. The surface of the third stirring rod 105 has liquid outlet holes 108. There are multiple sets of liquid outlet holes 108. The interior of the rotating shaft 103 has a through groove 107 at the bottom. The surface of the rotating shaft 103 has a liquid inlet 106 above the through groove 107. There are four sets of liquid inlet holes 106.

[0027] Specifically, the stirring motor 101 drives the first stirring rod 102 and the second stirring rod 104 to rotate, thereby stirring the liquid medicine inside the tank 204 to prevent the liquid medicine from settling. When the rotating shaft 103 rotates, it can drive the third stirring rod 105 to rotate. The liquid medicine enters the interior of the through-channel 107 through the liquid inlet 106 and is discharged through the liquid outlet 108. The liquid medicine and sewage are fully mixed, which helps to improve the sewage treatment efficiency. The stirring motor 101 is model JB / T6449, which can drive the rotating shaft 103 to rotate, thereby driving the first stirring rod 102, the second stirring rod 104, and the third stirring rod 105 to rotate and stir.

[0028] In a preferred embodiment, the medicine storage box 2 includes a medicine inlet 201, a drain outlet 202, a filter screen 203, and a box body 204. The medicine inlet 201 is embedded and installed on one side surface of the box body 204 at the top, and the drain outlet 202 is embedded and installed on one side surface of the box body 204 below the medicine inlet 201. The filter screen 203 is embedded and installed inside the box body 204.

[0029] Specifically, the medicine is delivered to the inside of the box 204 through the medicine inlet 201 and filtered by the filter screen 203. The filtered impurities are discharged through the drain outlet 202. The surface of the drain outlet 202 is equipped with a valve, which is normally closed. The filter screen 203 can intercept particulate matter in the medicine to prevent particulate matter from entering the water pump 501 and causing blockage. When impurities on the surface of the filter screen 203 need to be discharged, the valve on the drain outlet 202 can be opened.

[0030] In a preferred embodiment, the conveying structure 5 includes a water pump 501 and a conveying box 502, with the output end of the water pump 501 embedded inside the conveying box 502;

[0031] Specifically, the liquid medicine is transported into the delivery box 502 by the water pump 501. The water pump 501 is a metering pump, model APG600, which can transport a certain amount of liquid medicine into the delivery box 502.

[0032] In a preferred embodiment, the stirring motor 101 is embedded in the upper surface of the housing 204, the conveying box 502 is embedded in the lower surface of the housing 204 and sleeved on the surface of the rotating shaft 103, and the liquid level sensor 4 is embedded in the upper surface of the housing 204.

[0033] Specifically, by driving the stirring motor 101, the first stirring rod 102 and the rotating shaft 103 can stir the medicine solution, and the third stirring rod 105 can stir the medicine solution and sewage. When the water pump 501 is driven, a certain amount of medicine solution can enter the interior of the delivery box 502, and enter the through channel 107 through the liquid inlet 106, and be discharged through the liquid outlet 108. The third stirring rod 105 stirs and mixes the sewage. A sealing gasket is provided between the delivery box 502 and the rotating shaft 103. Water inside the box 204 can only enter the interior of the delivery box 502 through the medicine inlet 201. Even if a small amount of medicine solution seeps in when the rotating shaft 103 is rotating, it is a small amount and will not have a significant impact on the sewage treatment.

[0034] In a preferred embodiment, the support leg 3 includes a first support rod 301, a second support rod 302, a fixing bolt 303, and a base plate 304. The second support rod 302 is embedded in the lower surface of the first support rod 301 and fixed to the first support rod 301 by the fixing bolt 303. The base plate 304 is fixedly installed on the lower surface of the second support rod 302.
