A potassium iodide aerosol generator

Abstract

This invention belongs to the field of potassium iodide aerosol preparation technology, specifically relating to a potassium iodide aerosol generating device. It includes a generating chamber, a recovery tank, and a vortex disk. The generating chamber houses a liquid supply assembly and a collection assembly. The liquid supply assembly includes a feed pipe with a spray assembly mounted on it. A long pipe is attached to the feed pipe, passing through a sleeve and a corrugated pipe before being inserted into a storage tank. The spray assembly includes a ball head, a spray pipe, and an inner cylinder. A small-diameter inlet is formed on the side wall of the spray pipe, and a large-diameter inlet is formed on the side wall of the inner cylinder. This invention uses a cylinder to move the feed pipe upwards, causing the spray nozzles on the spray pipe to rotate from the center of the vortex disk towards its edge, thus impacting the crystals within the grooves of the vortex disk. As the spray pipe rotates, the inner cylinder slides into the spray pipe, and the small-diameter inlet on the spray pipe and the large-diameter inlet on the inner cylinder gradually overlap, increasing the solution spray volume and enhancing the impact intensity.

Description

Technical Field

[0001] This invention belongs to the field of potassium iodide aerosol preparation technology, and specifically relates to a potassium iodide aerosol generating device. Background Technology

[0002] Potassium iodide aerosol is prepared by suspending potassium iodide solution as tiny particles in a gaseous atmosphere. It is a dispersion system with unique physicochemical properties and has wide applications in medicine, industry, and scientific research. Physically, potassium iodide aerosol appears as a white or pale yellow cloud, visible to the naked eye but opaque.

[0003] Existing methods for preparing potassium iodide aerosols involve spraying a potassium iodide solution through a nozzle onto a vortex disk, with the vortex disk rotating to generate the aerosol. For example, there is a potassium iodide aerosol generating apparatus disclosed in CN222305739U.

[0004] However, the following technical problems exist in the preparation of potassium iodide aerosol. First, the preparation of potassium iodide aerosol requires applying centrifugal force to the potassium iodide solution through a high-speed rotating vortex disk, so that the potassium iodide solution is sheared through the vortex-shaped grooves on the vortex disk, tearing the liquid into tiny droplets. However, in this process, potassium iodide is prone to crystallize in the grooves of the vortex disk, which leads to a decrease in the shearing performance of the vortex disk and a decrease in the preparation efficiency of potassium iodide aerosol.

[0005] Secondly, when potassium iodide solution passes through the nozzle, potassium iodide crystals or impurities can easily clog the nozzle, causing obstruction and affecting the solution spraying speed. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by providing a potassium iodide aerosol generating device to solve the technical problems in the prior art.

[0007] The objective of this invention can be achieved through the following technical solution: a potassium iodide aerosol generating device, comprising a generating chamber, a recovery tank installed inside the generating chamber, a rotatable vortex disk installed on the recovery tank, an end cap installed on the top of the generating chamber, and a liquid supply assembly and a collection assembly installed inside the generating chamber; the liquid supply assembly includes a storage tank, the storage tank is connected to a sleeve through a corrugated pipe, the sleeve is connected to a liftable material pipe through a corrugated hose, a spraying assembly is installed on the material pipe, the spraying assembly faces the vortex disk, a long pipe is installed on the material pipe, the long pipe passes through the sleeve and the corrugated pipe and is inserted into the storage tank; the spraying assembly includes a ball head and a spray pipe, the spray pipe is fixedly installed inside the ball head, an inner cylinder is slidably installed inside the spray pipe, an inlet ring is fixedly installed inside the sleeve, the inlet ring is connected to a base plate through a longitudinal rod, the inner cylinder is rotatably installed with the base plate, a small-diameter inlet is opened on the side wall of the spray pipe, and a large-diameter inlet is opened on the side wall of the inner cylinder.

[0008] As a further optimization or improvement of this solution, a cylinder is installed inside the generating chamber, a side plate is installed on the side wall of the material pipe, and the output end of the cylinder is connected to the side plate.

[0009] As a further optimization or improvement to this solution, a motor is fixedly installed on the recycling pool, and the output end of the motor is connected to a vortex disk.

[0010] As a further optimization or improvement of this solution, the collection component includes a collection box, which is installed inside the generating box. The collection box is connected to a collection port, which draws potassium iodide aerosol into the collection box for storage.

[0011] As a further optimization or improvement of this solution, a recovery tank is installed inside the generating tank. The pump inside the recovery tank draws the potassium iodide solution that does not meet the requirements from the recovery pool into the recovery tank through a recovery pipe. After being processed by the recovery tank, the potassium iodide solution is transported to the storage tank.

[0012] As a further optimization or improvement of this solution, a spray nozzle and a sliding nozzle are respectively opened in the spray pipe. The inner cylinder is slidably installed inside the sliding nozzle. A baffle is slidably installed inside the small-diameter inlet. The baffle is connected to the inner wall of the sliding nozzle by a wave spring. A push plate is installed on the side of the large-diameter inlet. The push plate pushes the baffle to move.

[0013] As a further optimization or improvement to this solution, a pusher is installed on the inner cylinder, and the pusher is connected to the bottom plate via a connecting rod.

[0014] As a further optimization or improvement of this solution, a strong magnetic ring is installed inside the sleeve, and a strong magnet is installed on the outer edge of the liquid inlet ring, with the strong magnetic ring and the strong magnet attracting each other.

[0015] The beneficial effects of this invention are:

[0016] (1) In this invention, the cylinder drives the feed pipe to move upward. Since the inlet ring and the bottom plate are fixed, under the action of the ball head, the feed pipe drives the spray nozzle on the spray pipe to rotate from the center of the vortex plate towards the edge of the vortex plate, so that the solution can impact the crystals inside the groove of the vortex plate and flush the crystals into the recovery tank. As the spray pipe rotates, the inner cylinder slides into the spray pipe, and the small diameter inlet on the spray pipe and the large diameter inlet on the inner cylinder gradually overlap, that is, the solution spray volume increases, and the impact intensity is improved.

[0017] Specifically, during the upward movement of the feed pipe, the feed pipe drives the long pipe to move towards the top of the storage tank, and sprays the low-concentration potassium iodide solution at the top of the storage tank into the vortex disk through the spraying component. The low-concentration potassium iodide solution is beneficial for dissolving potassium iodide crystals and for eradicating crystals in the trench.

[0018] (2) In this invention, the cylinder continuously pushes the material pipe downward. Under the action of the ball head, the spray pipe rotates continuously, causing the spray nozzle on the spray pipe to rotate away from the vortex disk. At the same time, the inner cylinder slides into the spray pipe, and the push plate pushes the baffle to move and compress the wave spring. At this time, the diameter of the small-diameter inlet gradually increases. Impurities and crystals blocked on the small-diameter inlet enter the inner cylinder through the large-diameter inlet and are discharged from the spray nozzle. Since the spray pipe is away from the vortex disk, it can effectively avoid the phenomenon of impurities and crystals discharged from the spray assembly embedding into the groove of the vortex disk, causing groove blockage.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] See Figures 1-8 A potassium iodide aerosol generator includes a generating chamber 1, a recovery tank 10 installed inside the generating chamber 1, a rotatable vortex disk 8 installed on the recovery tank 10, an end cap 2 installed on the top of the generating chamber 1, and a liquid supply assembly 6 and a collection assembly 4 installed inside the generating chamber 1. The liquid supply assembly 6 includes a storage tank 601, which is connected to a sleeve 602 via a corrugated pipe. The sleeve 602 is connected to a liftable feed pipe 604 via a corrugated flexible hose 605. A spray assembly 9 is installed on the feed pipe 604, which faces the vortex disk 8. A long pipe 6 is installed on the feed pipe 604. 10. The long tube 610 passes through the sleeve 602 and the corrugated tube and is inserted into the liquid storage tank 601; the spray assembly 9 includes a ball head 901 and a spray pipe 902. The spray pipe 902 is fixedly installed inside the ball head 901. An inner cylinder 908 is slidably installed inside the spray pipe 902. An inlet ring 608 is fixedly installed inside the sleeve 602. The inlet ring 608 is connected to the base plate 609 through a longitudinal rod 607. The inner cylinder 908 is rotatably installed with the base plate 609. A small-diameter inlet 906 is opened on the side wall of the spray pipe 902, and a large-diameter inlet 911 is opened on the side wall of the inner cylinder 908.

[0032] Specifically, a cylinder 603 is installed inside the generating box 1, a side plate 606 is installed on the side wall of the material pipe 604, and the output end of the cylinder 603 is connected to the side plate 606.

[0033] Specifically, a motor 7 is fixedly installed on the recycling pool 10, and the output end of the motor 7 is connected to the vortex disk 8.

[0034] It should be noted that, initially, each group of spray pipes 902 faces the center of the vortex disk 8, increasing the distance the potassium iodide solution travels through the vortex-shaped grooves on the vortex disk 8, thus increasing the shearing force of the grooves on the liquid droplets and improving the efficiency of potassium iodide aerosol formation. A convection hole 12 is provided at the bottom of the generating chamber 1, primarily for heat dissipation of the motor 7. A handle 3 is installed on the end cover 2.

[0035] It should be noted that in the preparation of potassium iodide aerosol, high-purity potassium iodide powder and distilled water are first mixed to form a potassium iodide solution. This solution is then introduced into a storage tank 601. Next, by pressurizing the storage tank 601, the potassium iodide solution inside is transported through a long pipe 610 to a feed pipe 604. (See [reference]). Figure 6 , Figure 7 and Figure 4 The solution inside the feed pipe 604 enters the inner cylinder 908 through the small-diameter inlet 906 and the large-diameter inlet 911. The solution inside the inner cylinder 908 is sprayed through the spray nozzle 903 on the spray pipe 902, spraying the solution onto the central area of ​​the vortex disk 8. Simultaneously, the motor 7 operates, driving the vortex disk 8 to rotate at high speed. As the vortex disk 8 rotates, the centrifugal force on the solution causes it to be sheared into tiny droplets through the grooves on the vortex disk 8. (See [link to other documentation]). Figure 2 The liquid droplets are thrown out of the vortex disk 8 by the centrifugal force and mix with the air. The collection port 402 operates at a fixed power to draw qualified potassium iodide aerosol into the collection box 401 (the potassium iodide particles in the potassium iodide aerosol have a particle size between 1-5 μm). Unqualified potassium iodide aerosol falls into the recovery pool 10 under the action of gravity (the potassium iodide particles in the potassium iodide aerosol have a particle size greater than 6 μm).

[0036] If the potassium iodide solution crystallizes in the grooves on the vortex plate 8, cylinder 603 is activated. Cylinder 603 drives the feed pipe 604 and the injection assembly 9 to move upwards. See below. Figure 7 and Figure 6 During the upward movement of the feed pipe 604, since the sleeve 602, the inlet ring 608, and the base plate 609 are fixed, under the action of the ball head 901, the feed pipe 604 drives the spray nozzle 903 on the spray pipe 902 to rotate from the center of the vortex disk 8 towards the edge of the vortex disk 8, so that the solution can impact the crystals inside the groove of the vortex disk 8 and flush the crystals into the recovery tank 10. As the spray pipe 902 rotates, the inner cylinder 908 slides into the spray pipe 902, and the small-diameter inlet 906 on the spray pipe 902 and the large-diameter inlet 911 on the inner cylinder 908 gradually overlap, that is, the solution spray volume increases, and the impact intensity is enhanced.

[0037] During the upward movement of the feed pipe 604, the feed pipe 604 drives the long pipe 610 to move upward synchronously, so that the long pipe 610 moves toward the top layer of the storage tank 601, and sprays the low-concentration potassium iodide solution at the top layer of the storage tank 601 through the spray component 9 onto the vortex disk 8. The low-concentration potassium iodide solution is beneficial to dissolving potassium iodide crystals and to eradicating crystals on top of crystals in the trench.

[0038] It should be noted that after the potassium iodide solution is introduced into the storage tank 601 for a period of time, the high-concentration potassium iodide solution and undissolved potassium iodide particles settle to the bottom of the tank, while the low-concentration potassium iodide solution is placed on the top of the storage tank 601.

[0039] See Figure 9 A strong magnetic ring 611 is installed inside the sleeve 602, and a strong magnet 612 is installed on the outer edge of the liquid inlet ring 608. The strong magnetic ring 611 and the strong magnet 612 are attracted to each other.

[0040] It should be noted that, since the long tube 610 is located between the sleeve 602 and the inlet ring 608, and the sleeve 602 and the inlet ring 608 are fixedly connected by the attraction between the strong magnetic ring 611 and the strong magnet 612, in order to avoid the long tube 610 moving up and down and increasing the friction between the strong magnetic ring 611 and the strong magnet 612, needle rollers are provided on the strong magnet 612 and the strong magnetic ring 611 to reduce the interference of the long tube 610 movement on the strong magnetic ring 611 and the strong magnet 612.

[0041] See Figures 1-4 The generating tank 1 is equipped with a recycling tank 5. The recycling tank 5 has a built-in pump that draws the potassium iodide solution that does not meet the requirements from the recycling pool 10 into the recycling tank 5 through the recycling pipe 11. After being processed by the recycling tank 5, the potassium iodide solution is transported to the storage tank 601.

[0042] Specifically, the collection component 4 includes a collection box 401, which is installed inside the generating box 1. The collection box 401 is connected to a collection port 402, which draws potassium iodide aerosol into the collection box 401 for storage.

[0043] It should be noted that the built-in pump in the recovery tank 5 draws unsuitable potassium iodide from the recovery pool 10 into the recovery tank 5 and then delivers it to the liquid supply assembly 6. This invention utilizes the recovery tank 5 for the secondary use of potassium iodide.

[0044] See Figures 4-8 The spray pipe 902 has a spray nozzle 903 and a sliding nozzle 904 respectively. The inner cylinder 908 is slidably installed inside the sliding nozzle 904. A baffle 907 is slidably installed inside the small-diameter inlet 906. The baffle 907 is connected to the inner wall of the sliding nozzle 904 by a wave spring 905. A push plate 912 is installed on the side of the large-diameter inlet 911. The push plate 912 pushes the baffle 907 to move.

[0045] Specifically, a pusher 909 is installed on the inner cylinder 908, and the pusher 909 is connected to the base plate 609 via a connecting rod 910.

[0046] It should be noted that during use, the solution inside the feed tube 604 enters the inner cylinder 908 through the small-diameter inlet 906 and the large-diameter inlet 911 and is then discharged. Therefore, solution crystals and impurities can easily clog the small-diameter inlet 906.

[0047] Based on this, the present invention continuously pushes the material pipe 604 downward by the cylinder 603, and under the action of the ball head 901, the spray pipe 902 continuously rotates, causing the spray nozzle 903 on the spray pipe 902 to rotate away from the vortex disk 8. At the same time, the inner cylinder 908 slides into the spray pipe 902. See [reference needed] Figure 8 and Figure 4 During this process, the pusher plate 912 pushes the baffle 907 to move and compresses the wave spring 905. At this time, the diameter of the small-diameter inlet 906 gradually increases. Impurities and crystals blocked on the small-diameter inlet 906 enter the inner cylinder 908 through the large-diameter inlet 911 and are discharged from the spray port 903. Since the spray pipe 902 is far away from the vortex disk 8, it can effectively prevent impurities and crystals discharged from the spray assembly 9 from embedding into the grooves of the vortex disk 8, thus avoiding groove blockage.

[0048] It should be noted that the small-diameter inlet 906 in the fully open state can completely overlap with the large-diameter inlet 911.

[0049] The working principle of this invention is as follows: First, high-purity potassium iodide powder and distilled water are mixed to form a potassium iodide solution. This solution is then introduced into a storage tank 601. Next, by pressurizing the storage tank 601, the potassium iodide solution inside is transported through a long pipe 610 to a feed pipe 604. (See attached diagram.) Figure 6 , Figure 7 and Figure 4 The solution inside the feed pipe 604 enters the inner cylinder 908 through the small-diameter inlet 906 and the large-diameter inlet 911. The solution inside the inner cylinder 908 is sprayed through the spray nozzle 903 on the spray pipe 902, spraying the solution onto the central area of ​​the vortex disk 8. Simultaneously, the motor 7 operates, driving the vortex disk 8 to rotate at high speed. As the vortex disk 8 rotates, the centrifugal force on the solution causes it to be sheared into tiny droplets through the grooves on the vortex disk 8. (See [link to other documentation]). Figure 2 The liquid droplets are thrown out of the vortex disk 8 by the centrifugal force and mix with the air. The collection port 402 operates at a fixed power to draw qualified potassium iodide aerosol into the collection box 401; unqualified potassium iodide aerosol falls into the recovery pool 10 under the action of gravity.

[0050] If the potassium iodide solution crystallizes in the grooves on the vortex plate 8, cylinder 603 is activated. Cylinder 603 drives the feed pipe 604 and the spray assembly 9 to move upward. During the upward movement of the feed pipe 604, since the sleeve 602, the inlet ring 608, and the base plate 609 are fixed, under the action of the ball head 901, the feed pipe 604 drives the spray nozzle 903 on the spray pipe 902 to rotate from the center of the vortex plate 8 towards the edge of the vortex plate 8, so that the solution can impact the crystals inside the grooves of the vortex plate 8 and flush the crystals into the recovery tank 10. As the spray pipe 902 rotates, the inner cylinder 908 slides into the spray pipe 902, and the small-diameter inlet 906 on the spray pipe 902 and the large-diameter inlet 911 on the inner cylinder 908 gradually overlap, that is, the solution spray volume increases, and the impact intensity is enhanced.

[0051] During the upward movement of the feed pipe 604, the feed pipe 604 drives the long pipe 610 to move upward synchronously, so that the long pipe 610 moves toward the top layer of the storage tank 601, and sprays the low-concentration potassium iodide solution at the top layer of the storage tank 601 through the spray component 9 onto the vortex disk 8. The low-concentration potassium iodide solution is beneficial to dissolving potassium iodide crystals and to eradicating crystals in the trench.

[0052] Specifically, in this invention, the cylinder 603 continuously pushes the feed pipe 604 downward. Under the action of the ball head 901, the spray pipe 902 continuously rotates, causing the spray nozzle 903 on the spray pipe 902 to rotate away from the vortex disk 8. At the same time, the inner cylinder 908 slides into the spray pipe 902. See [link to relevant documentation]. Figure 8 and Figure 4 During this process, the pusher plate 912 pushes the baffle 907 to move and compresses the wave spring 905. At this time, the diameter of the small-diameter inlet 906 gradually increases. Impurities and crystals blocked on the small-diameter inlet 906 enter the inner cylinder 908 through the large-diameter inlet 911 and are discharged from the spray port 903. Since the spray pipe 902 is far away from the vortex disk 8, it can effectively prevent impurities and crystals discharged from the spray assembly 9 from embedding into the grooves of the vortex disk 8, thus avoiding groove blockage.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
