Description

Technical Field

[0001] The present application relates to the technical field of water treatment equipment, and in particular to a self-circulating dosing system. Background Art

[0002] In water treatment, mixing chemicals and water is a critical step in ensuring effective water treatment. Traditional mixing systems typically rely on at least two independent pumps to perform water inlet and outlet functions. One pump is responsible for pumping the water to be treated or clean water into the mixing tank to mix with the chemicals; the other pump is responsible for extracting the mixed liquid from the mixing tank and transporting it to subsequent treatment units or storage facilities.

[0003] While a dual-pump configuration effectively mixes and delivers the reagent and water, it also brings with it issues like increased costs, increased energy consumption, and increased system complexity. Both pumps consume electricity during operation, resulting in high overall energy consumption for water treatment and hindering the achievement of energy conservation and emission reduction goals. Furthermore, dual-pump configurations are more complex to maintain and manage, requiring regular checks on both pumps and timely replacement of worn parts, increasing both operational costs and workload.

[0004] Based on this, the present application proposes a self-circulating dosing system to solve the above technical problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] This application provides a self-circulating dosing system for reducing the number of pumps used in the water treatment process and lowering the energy consumption of water treatment. The specific implementation process of this application is described as follows.

[0033] See also Figures 1 to 4 , the present application provides a self-circulating dosing system comprising:

[0034] A stirring tank 01, a stirring nozzle 02, a circulation pump 03, a return pipe 04, a water inlet pipe 05 and a medicine outlet pipe 06. The stirring nozzle 02 is fixed in the stirring tank 01, and the circulation pump 03 is arranged on the water inlet pipe 05. The water inlet pipe 05 runs through the stirring tank 01 and is connected with the stirring nozzle 02. The water inlet pipe 05 is used to transport liquid into the stirring nozzle 02, and the stirring nozzle 02 is used to stir the mixed liquid in the stirring tank 01; one end of the return pipe 04 is connected to the bottom of the stirring tank 01, and the other end is connected to the circulation pump 03. The medicine outlet pipe 06 is connected to the water inlet pipe 05. The return pipe 04 is used to transport the mixed liquid in the stirring tank 01 to the circulation pump 03, so that the circulation pump 03 transports the mixed liquid to the medicine outlet pipe 06 through the water inlet pipe 05.

[0035] Mixing Tank 01 is used to hold liquids to be mixed, and can also accommodate solid components (such as solid pharmaceuticals). It can be used to mix liquids and solids. Made of corrosion-resistant materials such as stainless steel, Mixing Tank 01 accommodates the mixing needs of various chemicals. The tank is designed with suitable openings and seals for easy addition of raw materials and maintenance.

[0036] The agitating nozzle 02 is installed inside the mixing tank 01. It sprays liquid at high speed, creating strong shear forces and turbulence, effectively mixing the materials within the tank. In actual operation, when the water inlet pipe 05 delivers liquid to the agitating nozzle 02, the nozzle sprays the liquid in a fine, high-speed jet. The jet forms a vortex within the tank, promoting sufficient contact and mixing between the materials.

[0037] Circulation pump 03 is used to drive the circulation of the mixed liquid and provide power to the liquid in water inlet pipe 05. In actual operation, circulation pump 03 is responsible for both extracting the mixed liquid from the bottom of mixing tank 01 and returning it to mixing nozzle 02 through water inlet pipe 05 to form a cycle. It is also responsible for pumping external liquid into water inlet pipe 05, so that it flows into mixing nozzle 02 through water inlet pipe 05. Circulation pump 03 is installed on water inlet pipe 05, with one end connected to return pipe 04 and the other end connected to water inlet pipe 05, ensuring that the mixed liquid can be continuously extracted and re-injected into mixing tank 01. Return pipe 04 is responsible for guiding the mixed liquid at the bottom of mixing tank 01 to circulation pump 03.

[0038] The water inlet pipe 05 is not only used to deliver fresh liquid (such as water or solvent) to the mixing nozzle 02, but also serves as a channel for the mixed liquid to circulate. The water inlet pipe 05 works closely with the circulation pump 03 and the mixing nozzle 02 to ensure that the liquid can be supplied evenly and stably.

[0039] The drug outlet pipe 06 is the channel for the mixed liquid to be discharged after mixing. It is connected to the equipment or system that needs to add drugs. The drug outlet pipe 06 is connected to the water inlet pipe 05 downstream of the circulation pump 03 to ensure that only the fully mixed liquid can flow out.

[0040] In actual operation, the present application first turns on the circulation pump 03 and simultaneously injects liquid (such as water or solvent) into the water inlet pipe 05; the liquid enters the stirring nozzle 02 through the water inlet pipe 05, is ejected at high speed to form a vortex, and is mixed with the material in the stirring tank 01; the mixed liquid is extracted by the circulation pump 03 through the return pipe 04, and is again sent to the stirring nozzle 02 through the water inlet pipe 05, and so on and so forth until the required mixing uniformity is achieved; when the mixed liquid meets the predetermined requirements, it can be output to the target device or system through the medicine outlet pipe 06. In this way, the process of stirring, mixing and discharging medicine can be achieved by using only one circulation pump 03, which reduces the number of pumps involved in the work compared to the prior art, thereby reducing the energy consumption of water treatment; and the stirring in the stirring tank 01 is stirred by the stirring nozzle 02, and the stirring process is driven by the water inlet, without the need for additional power to control the stirring, thereby further reducing the power consumption required for mixing.

[0041] In an optional embodiment, a regulating pipe 07 is provided on the water inlet pipe 05, and a regulating valve 08 is installed on the regulating pipe 07. The two ends of the regulating pipe 07 are respectively connected to the water inlet pipe 05. In this embodiment, the regulating pipe 07 is a branch of the water inlet pipe 05, providing an additional fluid channel, allowing for fine-tuning of the flow rate of liquid entering the agitation nozzle 02 without interrupting the main circulation. The two ends of the regulating pipe 07 are respectively connected to different positions of the water inlet pipe 05, forming a water inlet bypass.

[0042] Regulating valve 08 is mounted on regulating tube 07 and is used to control the flow of liquid through regulating tube 07. By adjusting the opening of valve 20, the amount of liquid entering mixing nozzle 02 can be precisely adjusted, thereby optimizing the mixing process. Regulating valve 08 can be manually controlled or automatically controlled (for example, via an electric actuator or a pneumatic actuator). Automatically controlled regulating valve 08 can automatically adjust its opening according to preset parameters (such as flow rate, pressure, or liquid level), achieving more advanced flow control.

[0043] By setting the regulating pipe 07 and the regulating valve 08, the flow rate entering the stirring nozzle 02 can be adjusted, and the flow rate of the mixed liquid in the medicine outlet pipe 06 can also be adjusted.

[0044] In this optional embodiment, a first flow meter 09 and a second flow meter 10 are provided on the water inlet pipe 05, and the first flow meter 09 and the second flow meter 10 are respectively located at the two ends of the regulating pipe 07. In this embodiment, the first flow meter 09 and the second flow meter 10 respectively measure the flow of the water inlet pipe 05 at the two ends of the regulating pipe 07, and can reflect the real-time data on the flow of the main circulation path and the bypass path (i.e., the regulating pipe 07). The first flow meter 09 is usually located on the water inlet pipe 05 upstream of the regulating pipe 07, and is used to measure the total flow entering the entire system (including the main circulation and the bypass), and the second flow meter 10 is located on the water inlet pipe 05 downstream of the regulating pipe 07, and is used to measure the flow that continues to enter the stirring nozzle 02 after adjustment by the regulating valve 08. The flow meter can be of various types, such as an electromagnetic flow meter, an ultrasonic flow meter or a turbine flow meter. The specific selection is not limited here, and is subject to actual achievable results.

[0045] In an optional embodiment, a liquid level gauge 11 is provided in the mixing tank 01, and the liquid level gauge 11 is used to measure the remaining amount of liquid in the mixing tank 01. In this embodiment, by installing the liquid level gauge 11 on the side wall or top of the mixing tank 01, the actual height of the liquid in the tank can be accurately measured. The liquid level gauge 11 can be one of various types, such as a float-type liquid level gauge 11, an ultrasonic liquid level gauge 11, a radar liquid level gauge 11, a pressure liquid level gauge 11, and a capacitive liquid level gauge 11. The specific selection is not limited here, and is subject to actual achievable implementation.

[0046] In an optional embodiment, the stirring nozzle 02 includes a shell 12, a cover plate 13 and a swirl booster blade 14; the cover plate 13 is connected to the shell 12, and a flow space is formed between the cover plate 13 and the shell 12. The swirl booster blade 14 is arranged in the flow space, and the two ends of the swirl booster blade 14 are movably connected to the shell 12 and the cover plate 13 respectively; a nozzle 15 is provided on the cover plate 13, and the water outlet end of the nozzle 15 faces the swirl booster blade 14. The water inlet pipe 05 is connected to the nozzle 15, and the nozzle 15 is used to spray the liquid in the water inlet pipe 05 toward the swirl booster blade 14 to promote the swirl booster blade 14 to rotate; a penetrating swirl water spray port 16 is provided on the side of the shell 12, and the swirl water spray port 16 is used to spray the water flow in the flow space into the stirring tank 01.

[0047] The cover plate 13 is connected to the housing 12, forming a closed flow space. A nozzle 15 is mounted on the cover plate 13, extending vertically through the cover plate 13. The outlet of the nozzle 15 faces the swirl booster blades 14. One end of the nozzle 15, located outside the cover plate 13, is connected to the water inlet pipe 05. When liquid in the water inlet pipe 05 flows into this flow space through the nozzle 15, the liquid ejected from the nozzle 15 impacts the swirl booster blades 14.

[0048] The swirl booster blade 14 is located in the flow space formed by the cover plate 13 and the shell 12. Both ends of the swirl booster blade 14 are movably connected to the shell 12 and the cover plate 13 respectively, allowing the swirl booster blade 14 to rotate freely under the push of the liquid.

[0049] The nozzle 15 is responsible for spraying the liquid in the water inlet pipe 05 toward the swirl booster blades 14 at a certain speed and pressure. The water outlet end of the nozzle 15 is oriented toward the swirl booster blades 14, ensuring that the liquid can directly impact and drive the swirl booster blades 14 to rotate. When the liquid is sprayed toward the swirl booster blades 14 through the nozzle 15, the swirl booster blades 14 are impacted by the liquid and begin to rotate. A swirl water spray port 16 is provided through the side of the housing 12. The water flow in the flow space has a certain flow rate under the rotation of the swirl booster blades 14. The water is sprayed into the mixing tank 01 in the form of a swirl through the swirl water spray port 16. The swirl water spray method not only enhances the stirring effect, but also helps to evenly mix the liquid in the mixing tank 01.

[0050] In an optional embodiment, a guide plate 17 is provided on the swirl water jet 16. The guide plate 17 is controllably rotatable within the swirl water jet 16 and serves to guide the direction of the water jet. In this embodiment, the guide plate 17 is mounted within the swirl water jet 16 and is typically connected to the housing 12 via a bearing or similar rotating mechanism, allowing the guide plate 17 to rotate freely within a certain range. The guide plate 17 vertically divides the water jet into two parts. The function of the guide plate 17 is to guide the direction of the water jet. By adjusting the angle of the guide plate 17, the water jet trajectory and the location of vortex generation can be changed, thereby affecting the flow pattern and mixing effect of the fluid in the mixing container.

[0051] In an optional embodiment, a dosing hopper 18 is located on the top of the mixing tank 01, and a removable filter is installed inside the dosing hopper 18. In this embodiment, the dosing hopper 18 is located on the top of the mixing tank 01 and can be designed in a funnel shape to facilitate the addition of solid or liquid medications. The dosing hopper 18 is made of corrosion-resistant, easy-to-clean materials such as stainless steel or food-grade plastic to ensure compatibility with the liquid and medication in the mixing tank 01, while also being easy to maintain and clean.

[0052] The filter is located inside the dosing hopper 18 and is used to filter out impurities and large solids from the medication, preventing them from entering the mixing tank 01 and affecting the mixing effect or damaging the mixing equipment. The filter edge is designed with easy-to-remove and easy-to-install connectors, such as snaps, threads, or quick-release clips, allowing for easy removal for cleaning or replacement when needed.

[0053] In an optional embodiment, the circulation pump 03 is one of a centrifugal circulation pump 03, an axial flow circulation pump 03, and a magnetic circulation pump 03.

[0054] In an optional embodiment, the return pipe 04 is connected to the mixing tank 01 via a flange 19. In this embodiment, a water outlet is provided at the bottom of the mixing tank 01, and a flange 19 is provided on the water outlet. A flange 19 is also provided on the return pipe 04. The flanges 19 of the two are aligned and then connected via bolts. In addition, a sealing ring can be provided between the two flanges 19 to improve the airtightness of the connection.

[0055] In an optional embodiment, a valve 20 is provided on the reflux pipe 04. In this embodiment, the valve 20 can be a manual valve 20 or an electric valve 20. By providing the valve 20, the reflux pipe 04 can be opened at any time, providing convenience for the outflow of the mixed liquid.

[0056] It should be noted that the above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of the present application.
