Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a shaftless stirring agent dissolution device. Background Technology

[0002] In wastewater treatment, the dissolution of solid chemicals in clean water is a core pretreatment step. If the dissolution is uneven or the concentration is not properly controlled, it will directly lead to waste of chemicals, reduced treatment effect (such as insufficient coagulation and flocculation), and even equipment blockage (such as pipes and pumps). The core objective of the mixing device is to convert solid chemicals into a uniform, stable, and lumpy liquid to ensure that it can be quickly mixed with wastewater and play its role when added later.

[0003] As wastewater treatment volumes increase, the demand for chemical dissolution also rises. Conventional mixing equipment is expensive, and simple PE tanks require separate mixing equipment. However, for large-scale treatment sites, the capacity of PE tanks is relatively large, typically reaching 10 tons of chemicals. Mixing equipment struggles to achieve effective mixing, resulting in incomplete chemical dissolution. Furthermore, since multiple PE tanks are individually configured, the dissolved solvent varies, making it difficult to achieve uniformity. Therefore, this paper aims to optimize existing technologies to improve the dissolution of solid chemicals and the consistency of chemical concentration. Utility Model Content

A dosing pipeline is installed on the main tank. An auxiliary tank is installed on one side of the main tank. The clean water pipeline is connected to the main tank and the auxiliary tank. The bottom of the main tank and the auxiliary tank are respectively connected to liquid pump a and liquid pump b. The output end of liquid pump a is connected to the input end of the auxiliary tank through a circulation pipeline. The output end of liquid pump b is connected to the input end of the main tank through a return pipeline.

[0006] As a further embodiment of this utility model: the return pipeline is connected to an output branch pipe a via a three-way valve, and the circulation pipeline is connected to an output branch pipe b via a three-way valve. Both output branch pipe a and output branch pipe b are connected to the pharmaceutical pipeline.

[0007] As a further improvement of this utility model: the main tank and the auxiliary tank have the same structure; The main tank includes a tank body, a dissolving cage, a drain hole, and a flushing pipe. The dissolving cage, which intercepts solid agents, is installed on the inner top of the tank body via a flange. The bottom of the dissolving cage is provided with a drain hole for the dissolving liquid to flow out. A flushing pipe, which extends into the dissolving cage, is installed on the outer side of the tank body to flush out solid agents.

[0008] As a further improvement of this utility model: the interior of the dissolving cage is provided with a flow divider seat that can separate the liquid phase output from the flushing pipe, and a flow guide plate is provided on the top of the flow divider seat.

[0009] As a further improvement of this utility model: the flow divider is cone-shaped, with the middle protrusion facing the bottom of the flushing pipe. The liquid phase output from the flushing pipe is cut at the bottom of the flow channel by the flow divider and the guide plate and discharged from the drain hole.

The reagent solution mixed in this way has a uniform concentration. Furthermore, when demand is high, other auxiliary tanks can be added, making it more adaptable and allowing for flexible adjustment and expansion to meet industrial needs, all at a low cost.

[0015] Please see Figures 1-3 In this embodiment of the invention, a shaftless stirring agent dissolving device includes a water pipeline 1 and a main tank 2. A dosing pipeline is installed on the main tank 2, and a secondary tank 3 is located on one side of the main tank 2. The water pipeline 1 connects to both the main tank 2 and the secondary tank 3. The bottoms of the main tank 2 and the secondary tank 3 are connected to a liquid pump a6 and a liquid pump b7, respectively. The output end of liquid pump a6 is connected to the input end of the secondary tank 3 via a circulation pipeline 9, and the output end of liquid pump b7 is connected to the input end of the main tank 2 via a return pipeline 13. A solid agent, such as a powdered or granular agent, is added to the main tank 2 or the secondary tank 3, and a measured amount of water is injected, such as a solid agent to water mass ratio of 1:4. The liquid pump is started, and the liquid in the main tank 2 enters the secondary tank 3 from the lower outlet. The liquid is pressurized by the pump and sent to the top of the auxiliary tank 3 through the circulation pipeline 9. The liquid flows downward to the bottom of the auxiliary tank 3 and returns to the inlet of the pump through the bottom outlet of the auxiliary tank 3. It is then pumped into the main tank 2 and mixed with the liquid in the main tank 2 before circulating again. During the circulation process, the solid agent gradually dissolves and diffuses throughout the system, eventually forming a uniform agent solution in the main tank 2 and the auxiliary tank 3. Once the solution concentration meets the standard, such as a dissolution rate of ≥98%, the circulation pump is stopped, and the dissolution of the solid agent is completed. The agent solution mixed in this way has a uniform concentration. When the demand is large, other auxiliary tanks 3 can be added in this way, which has higher adaptability and can be freely adjusted and increased according to industrial needs, and the cost is low.

[0016] In a preferred embodiment, the return line 13 is connected to the output branch a11 via a three-way valve 8, and the circulation line 9 is connected to the output branch b10 via a three-way valve 8. Both the output branch a11 and the output branch b10 are connected to the medicine line 12. By switching the three-way valve 8, the medicine solution in the main tank 2 and the auxiliary tank 3 can be discharged through the medicine line 12.

[0017] In a preferred embodiment, the main tank 2 and the auxiliary tank 3 have the same structure; The main tank 2 includes a tank body 201, a dissolving cage 202, a drain hole 204, and a flushing pipe 207. The dissolving cage 202, which intercepts solid reagents, is installed on the inner top of the tank body 201 via a flange 203. The bottom of the dissolving cage 202 is provided with a drain hole 204 for the dissolving liquid to flow out. The flushing pipe 207, which extends into the dissolving cage 202, is installed on the outer side of the tank body 201 to flush out solid reagents. The function of the dissolving cage 202 inside the main tank 2 is to intercept precipitated solid reagents. Undissolved solid reagents in the auxiliary tank 3 are pumped into the main tank 2 by the liquid pump b7 and intercepted by the dissolving cage 202. The solid reagents intercepted in the dissolving cage 202 are continuously flushed by the solvent output from the flushing pipe 207, thereby accelerating their dissolution rate. This method can effectively reduce the discharge of undissolved solid reagents, thereby achieving uniform mixing.

[0018] In a preferred embodiment, the dissolving cage 202 is provided with a diversion seat 205 that can divert the liquid phase output from the flushing pipe 207. A guide plate 206 is provided on the top of the diversion seat 205. The diversion seat 205 is conical in shape, with the middle protrusion facing the bottom of the flushing pipe 207. The liquid phase output from the flushing pipe 207 is cut off at the bottom of the diversion channel by the diversion seat 205 and the guide plate 206 and discharged from the drain hole 204. The function of the guide plate 206 is to separate the water flow. The solid agent is sent into the dissolving cage 202 by a liquid pump. Therefore, the solution will contain solid agent. In order to avoid uneven distribution of solid agent and blockage of the drain hole 204 on one side, the guide plate 206 is provided not only to distribute the solution, but also to distribute the undissolved solid agent.

[0019] In a preferred embodiment, the clean water pipeline 1 is connected to the flushing pipes 207 of the main tank 2 and the auxiliary tank 3 via the main tank pipeline 4 and the auxiliary tank pipeline 5, respectively. Valves are installed on the main tank pipeline 4 and the auxiliary tank pipeline 5 to control the water path. The return pipeline 13 is connected to the main tank pipeline 4, and a one-way valve is installed at the end of the return pipeline 13 near the main tank pipeline 4. The circulation pipeline 9 is connected to the auxiliary tank pipeline 5, and a one-way valve is installed at the end of the circulation pipeline 9 near the auxiliary tank pipeline 5. Whether it is fresh clean water entering the clean water pipeline 1 or circulating solution entering the return pipeline 13, it needs to be injected into the tank through the flushing pipe 207 to flush the solid agent. Therefore, the pipeline is designed with this connection method, and the one-way valve prevents the circulating solvent pressure from flowing back to the main tank pipeline 4.

[0020] It should be noted that all the above embodiments belong to the same utility model concept, and the descriptions of each embodiment have different focuses. Where the description in a particular embodiment is not detailed, please refer to the description in other embodiments.

[0021] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
