Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an automatic stirring and precise dosing device for seawater desalination. Background Technology

[0002] Seawater desalination is a technology that removes salt, minerals, and other impurities from seawater to obtain fresh water. Due to the uneven distribution of freshwater resources globally and the scarcity of freshwater in some areas, while seawater resources are abundant, seawater desalination technology is particularly important to meet the needs of drinking water and industrial water use. Seawater desalination is mainly achieved through methods such as distillation (using heat energy to evaporate seawater and then condense it) and reverse osmosis (forcing water through a semi-permeable membrane under pressure, while retaining salt and other impurities). Seawater desalination stirring and dosing equipment is mainly used in the seawater pretreatment stage to thoroughly mix the added agents (such as flocculants and disinfectants) with the seawater through stirring, thereby removing suspended solids, microorganisms, and other impurities from the seawater, ensuring the efficient operation of subsequent desalination processes, and improving the quality of desalinated water.

[0003] Seawater desalination dosing equipment typically includes a stirring motor, stirring shaft, stirring blades, reagent storage tank, metering pump, and piping. Its working principle is as follows: the required reagents are first stored in the storage tank. The metering pump precisely extracts the reagents according to the set dosage and delivers them to the stirring area through the piping. Then, the stirring motor drives the stirring shaft to rotate, causing the stirring blades to rotate at high speed, thoroughly stirring the seawater with the added reagents. This ensures the reagents are evenly dispersed in the seawater, allowing them to better react with impurities and facilitating the smooth progress of subsequent seawater desalination processes.

[0004] In existing technologies, metering pumps experience wear and aging over long-term use, leading to decreased accuracy and deviations in the extracted dosage. This makes it difficult for some devices to accurately control the dosage and timing of dosing, resulting in poor seawater pretreatment effects, impacting subsequent desalination efficiency and desalinated water quality, and increasing operating costs and equipment maintenance difficulty. Therefore, an automatic stirring and precise dosing device for seawater desalination is proposed to solve the above problems. Utility Model Content

When the piston moves upward, the feed valve opens, and the reagent enters the lower part of the piston from the top of the piston through the feed valve. When the piston moves downward, the feed valve closes, and the reagent enters the upper space of the piston from the stirring drum through the pressure difference. The piston then drives the sealing plug to open, allowing the reagent below the piston to be pushed out into the dosing cylinder. By controlling the operation of the air pump, the dosage and time of the reagent can be precisely controlled, so that the equipment can accurately dosing reagent according to the actual needs of seawater desalination, ensuring stable desalination effect, improving water quality, making the desalination process more scientific and efficient, avoiding reagent waste, and reducing costs.

[0029] 2. In this utility model, the agent is added into the feed cylinder by opening the sealing cover, thereby allowing the agent to enter the mixing drum. Then, the rotating column is driven by the motor to rotate, which makes the elevator and the stirring paddle work. The stirring paddle mixes the agent, and the elevator realizes the exchange of agents between the bottom and top layers to improve the mixing efficiency. This achieves efficient mixing of the agents required for seawater desalination, thereby accelerating the chemical reaction process related to seawater desalination, improving the efficiency of seawater desalination, shortening the overall processing time, and ensuring that the desalination effect is uniform throughout the seawater, thus improving the stability and reliability of the desalinated water quality.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figures 1 to 3 This utility model provides an embodiment of an automatic stirring and precise dosing device for seawater desalination, comprising a stirring drum 1, a stirring mechanism 2 fixedly connected to the top of the stirring drum 1, the stirring mechanism 2 being used to fully stir different agents. A transport component is provided on the outside of the stirring mechanism 2, used to transport the stirred mixed agents to subsequent mechanisms. A feeding mechanism 3 is fixedly connected to the top of the stirring drum 1, used to add the required agents to the stirring mechanism 2. A support mechanism 4 is fixedly connected to the bottom of the stirring drum 1, used to stabilize the entire dosing device. A dosing cylinder 5 is fixedly connected to the inner wall of the support mechanism 4, used to precisely control the dosage. A drive mechanism 6 is fixedly connected to the top of the dosing cylinder 5, used to control the dosage of the dosing cylinder 5 and subsequent mechanisms. A metering mechanism 7 is fixedly connected to the bottom of the drive mechanism 6, used to precisely meter the dosing agent. A display bar 8 is provided on the outside of the dosing cylinder 5, used to visually indicate the dosage.

[0039] The dispensing mechanism 7 includes a piston 701. The top of the piston 701 is fixedly connected to the bottom of the drive mechanism 6, and the outer wall of the piston 701 is slidably connected to the inner wall of the dosing cylinder 5. The movement of the piston 701 controls the feeding and dispensing of the drug. A rubber ring 702 is fitted on the outer side of the piston 701 to prevent direct friction damage between the piston 701 and the dosing cylinder 5, and also to maintain good sealing. A feed valve 704 is slidably connected to the inner wall of the piston 701. The feed valve 704 controls the drug to be squeezed under the piston 701 and then dispensed. Multiple sliding columns 705 are fixedly connected to the outer wall of the feed valve 704. Multiple sliding grooves 703 are opened on the inner side of the piston 701. The outer wall of the sliding column 705 is slidably connected to the inside of the sliding groove 703. The sliding of the sliding column 705 in the sliding groove 703 allows the feed valve 704 to slide stably inside the piston 701, thereby accurately controlling the amount of drug dispensed. The feed valve 704 has multiple outlet holes 706 on its exterior. These outlet holes 706 allow for the flow of the medicine. The upward movement of the piston 701 increases the pressure at its top, causing the feed valve 704 to move downwards relative to the piston 701. This allows for airflow between the outlet holes 706 and the bottom of the piston 701, enabling the medicine to enter from the top of the piston 701 to the bottom. A medicine dispensing assembly is fixedly connected to the bottom of the piston 701.

[0040] The dispensing assembly includes multiple follower columns 707, the tops of which are fixedly connected to the bottom of the piston 701, allowing the follower columns 707 to move synchronously with the piston 701. A sealing plug 708 is fixedly connected to the bottom of each follower column 707. The bottom of the mixing cylinder 1 has multiple dosing holes, and the shape of the sealing plug 708 matches the shape of the dosing holes. When the piston 701 moves upward, it drives the follower columns 707 upward, which in turn drives the sealing plug 708 upward to seal the dosing holes, preventing drug leakage during dispensing. Conversely, when the piston 701 moves downward, it drives the follower columns 707 downward, causing the sealing plug 708 to separate from the dosing holes, thus pushing the drug at the bottom of the piston 701 out of the dosing cylinder 5. Two sealing rings 709 are fixedly connected to the outer wall of the sealing plug 708. The sealing rings 709 ensure overall sealing when the piston 701 contacts the dosing holes, preventing drug leakage.

[0041] The drive mechanism 6 includes a gantry frame 601, the bottom of which is fixedly connected to the top of the dosing cylinder 5. The gantry frame 601 supports the entire drive mechanism 6. An air pump 602 is fixedly connected to the top of the gantry frame 601. The air pump 602 is the power source for the entire drive mechanism 6, driving the subsequent mechanisms to move vertically. A connecting plate 603 is fixedly connected to the output end of the air pump 602. Multiple transmission columns 604 are fixedly connected to the bottom of the connecting plate 603. The top of the piston 701 is fixedly connected to the bottom of the multiple transmission columns 604. The connecting plate 603 and the transmission columns 604 transmit the vertical power of the air pump 602, thereby driving the piston 701 to move vertically through the connecting plate 603 and the transmission columns 604.

[0042] Reference Figure 2 , Figure 4 , Figure 5The stirring mechanism 2 includes a motor 201, whose outer wall is fixedly connected to the top of the stirring drum 1. The motor 201 provides power to the entire stirring mechanism 2. A rotating column 202 is fixedly connected to the output end of the motor 201. The outer wall of the rotating column 202 is rotatably connected to the top of the stirring drum 1. The rotating column 202 transmits the rotational power of the motor 201 to the subsequent stirring components and stabilizes the rotation of the rotating column 202 through the stirring drum 1. A lifter 203 is fixedly connected to the outer wall of the rotating column 202. During operation, the lifter 203 rotates at high speed, and the mechanical structure of the spiral blades of the lifter 203 transports the lower layer of medicine to the upper layer, thereby increasing the stirring effect and making the stirring more thorough. Two stirring paddles 204 are fixedly connected to the outer wall of the rotating column 202. The outer wall of the stirring paddles 204 contacts the inner wall of the stirring drum 1. The gap between the stirring paddles 204 and the inner wall of the stirring drum 1 is precisely controlled within a very small range to ensure that the drum wall is thoroughly scraped during operation, preventing the adhesion and accumulation of medicine and impurities. The transport components are located inside the mixing drum 1.

[0043] The transport assembly includes a discharge pipe 205, the outer wall of which is fixedly connected to the inner wall of the mixing drum 1. The discharge pipe 205 is used to transport the stirred bottom layer of reagent to the dosing cylinder 5. When the piston 701 in the dosing cylinder 5 moves downward, the pressure in the space above the piston 701 decreases, thereby causing the reagent at the bottom of the mixing drum 1 to enter the dosing cylinder 5 through the discharge pipe 205 due to the pressure difference. A filter plate 206 is fixedly connected to the inner wall of the discharge pipe 205. The filter plate 206 is used to ensure the purity of the reagent entering the mixing drum 1 and to prevent impurities from participating in the reaction and interfering with the seawater desalination chemical reaction process.

[0044] The feeding mechanism 3 includes multiple feeding cylinders 301, the bottom of which is fixedly connected to the top of the mixing tank 1. The feeding cylinders 301 are used for adding reagents. A rotating shaft 302 is fixedly connected to the outside of each feeding cylinder 301, allowing subsequent structures to rotate along it. A sealing cover 303 is rotatably connected to the outer wall of the rotating shaft 302. A sealing ring 304 is fixedly connected to the bottom of the sealing cover 303. The outer wall of the sealing ring 304 is detachably connected to the top of the feeding cylinder 301. After adding reagents, the sealing cover 303 is closed, and the pressure between the sealing cover 303 and the feeding cylinder 301 causes the sealing ring 304 to deform, filling the gap between the sealing cover 303 and the feeding cylinder 301. This ensures the entire feeding mechanism 3 maintains good sealing, preventing external interference and impurities from entering the entire dosing device. The bottom of the feed cylinder 301 is fixedly connected to the feed pipe 305, and the other end of the feed pipe 305 is fixedly connected to the inside of the dosing cylinder 5. The feed pipe 305 is used for the medicine to enter the mixing cylinder 1.

[0045] The support mechanism 4 includes a support base 401, the top of which is fixedly connected to the bottom of the mixing drum 1. The support base 401 is used to stabilize the operation of the entire mixing drum 1. A connecting rod 402 is fixedly connected to the outer wall of the support base 401, providing an installation position for the support base 401. A fixing ring 403 is fixedly connected to the other end of the connecting rod 402. The outer wall of the dosing cylinder 5 is fixedly connected to the inner wall of the fixing ring 403, which bears the weight of the mixing drum 1 and the dosing cylinder 5. Multiple support columns 404 are fixedly connected to the bottom of the fixing ring 403, providing support and a foundation for the operation of the entire dosing equipment.

[0046] Working principle: In use, the desalination agent is added by opening the sealing cover 303. After closing the cover, the motor 201 is turned on. The motor 201 drives the rotating column 202 to rotate, which in turn drives the elevator 203 and the stirring paddle 204 to rotate. The rotation of the stirring paddle 204 mixes the agent in the mixing drum 1, while the rotation of the elevator 203 transports the agent at the bottom of the mixing drum 1 to the top of the mixing drum 1, thereby realizing the continuous exchange of the bottom and top agents and improving the mixing efficiency.

[0047] Turn on the air pump 602 again. The air pump 602 drives the connecting plate 603 to move vertically, which in turn drives the piston 701 to move vertically through the transmission column 604. When the piston 701 moves downward, the pressure in the space above the piston 701 decreases. This pressure difference causes the agent at the bottom of the mixing drum 1 to enter the dosing cylinder 5 through the transport action of the discharge pipe 205 and the filtration action of the filter plate 206. At the same time, the feed valve 704 in the piston 701 moves upward relative to the piston 701, separating the discharge hole 706 on the feed valve 704 from the space below the piston 701. The feed valve 704 closes, and the agent is retained above the piston 701. As the piston 701 moves upward again, the pressure at the top of the piston 701 increases, causing the feed valve 704 to be filled with the agent. Under the influence of gravity and pressure, the material slides downwards until the outlet 706 connects with the space below the piston 701, allowing the medicine above the piston 701 to enter the space below the piston 701. At this time, as the piston 701 moves upwards, the synchronous upward movement of the follower column 707 drives the sealing plug 708 to move upwards, leaving the medicine below the piston 701. This continues until the piston 701 moves downwards again, closing the feed valve 704 and forming a sealed unit with the piston 701. The downward movement of the piston 701 drives the follower column 707 downwards, causing the sealing plug 708 to move downwards and separate from the bottom of the dosing cylinder 5. The pressure of the piston 701 then causes the medicine below the piston 701 to flow out of the dosing cylinder 5. The operation of the control air pump 602 can be observed through the display bar 8 to precisely control the dosage and time of the medicine.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
