Description

Technical Field

[0001] The invention belongs to the technical field of chlorine dioxide preparation, and in particular relates to an activation device for preparing a disinfectant based on stable chlorine dioxide. Background Art

[0002] Chlorine dioxide is an inorganic compound that is a yellow-green to orange-yellow gas at room temperature and pressure. Chlorine dioxide has strong oxidizing and bactericidal properties and is primarily used for bleaching pulp and paper, fiber, wheat flour, and starch, as well as for disinfecting drinking water, food, and healthcare applications.

[0003] There are several methods for preparing stabilized chlorine dioxide, one of which is acid activation. During acid activation, the addition rate and temperature control of the stabilized chlorine dioxide are crucial. This is because, under acidic conditions, the activation process of stabilized chlorine dioxide occurs through the reaction of chloride ions in the acidic medium with chlorine dioxide. Generally speaking, the addition rate of stabilized chlorine dioxide should be within an appropriate range, neither too fast nor too slow. Too fast an addition rate can lead to unstable product quality and difficulty in control; too slow an addition rate can slow the reaction rate, affecting production efficiency.

[0004] Ultrasonic technology can enhance mass transfer, diffusion, and conduction in the reaction system, thereby accelerating the activation of stabilized chlorine dioxide. Furthermore, ultrasound can destroy the surface layer of bubbles and particles, increasing their contact area with the reactants and promoting the reaction.

[0005] However, in acidic activation, the ultrasonic frequency is not adjusted synchronously with the dripping speed, which will cause a reaction deviation between the two adjustments, affect the efficiency of activation, and increase the complexity of the work.

[0006] For example, Chinese patent publication No. CN107509742B discloses a method and apparatus for producing an active chlorine dioxide disinfectant, which uses tap water as an absorption liquid to maximize the absorption and dissolution of chlorine dioxide gas. However, the method does not synchronously adjust the ultrasonic frequency while adjusting the dripping speed during acidification activation, which will cause a reaction deviation between the two adjustments, affect the activation efficiency, and increase the complexity of the work. Summary of the Invention

[0007] The purpose of the present invention is to provide an activation device for preparing disinfectants based on stable chlorine dioxide, which can synchronously adjust the ultrasonic frequency while adjusting the dripping speed, thereby improving the efficiency of the adjustment, avoiding reaction instability caused by excessive deviation between the two due to adjustment, ensuring the efficiency of activation, and reducing the tediousness of the work.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive of other embodiments.

[0045] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0046] Please see the attached Figures 1 to 4 As shown, an activation device for preparing a disinfectant based on stable chlorine dioxide is provided, comprising a reaction tank 1, an ultrasonic unit 10, a liquid storage unit 20, a dripping unit 40 and a frequency modulation unit 50. The ultrasonic unit 10 is installed on the reaction tank 1 and is used to generate ultrasonic waves inside the reaction tank 1. The liquid storage unit 20 is installed on the reaction tank 1 and is used to drip liquid into the reaction tank 1. The dripping unit 40 is installed at the lower part of the liquid storage unit 20 and is used to adjust the speed of liquid dripping. The frequency modulation unit 50 is installed on a side of the liquid storage unit 20 close to the dripping unit 40. One end of the frequency modulation unit 50 is connected to one end of the dripping unit 40. The frequency modulation unit 50 is used to adjust the speed of liquid dripping and the frequency of ultrasonic waves at the same time. When the dripping unit 40 adjusts the liquid dripping speed inside the liquid storage unit 20, it will drive the frequency modulation unit 50 to follow the movement, so that the frequency modulation unit 50 synchronously adjusts the ultrasonic frequency generated by the ultrasonic unit 10.

[0047] Specifically, raw materials for preparing chlorine dioxide disinfectant are added to the inside of the reaction tank 1, and the liquid required for activation is added to the liquid storage part 20. When adjusting the activation reaction, the dripping part 40 is adjusted, and then the liquid dripping speed inside the liquid storage part 20 is adjusted, and at the same time, the frequency modulation part 50 is driven to follow the movement, so that the frequency modulation part 50 synchronously adjusts the ultrasonic frequency generated by the ultrasonic part 10, which can avoid reaction instability caused by excessive deviation in adjustment between the two, thereby ensuring the efficiency of activation.

[0048] In a preferred embodiment, see Figure 2 and Figure 3 The ultrasonic part 10 includes a motor 11, a stirring rod 12, a bevel gear a13, a bevel gear b14, an ultrasonic vibrator 15, an electric slip ring 16 and an ultrasonic generator 17. The motor 11 is fixed at the upper end of the reaction tank 1, and the stirring rod 12 is rotatably connected to the inside of the reaction tank 1. The bevel gear a13 is fixed to the output end of the motor 11, and the bevel gear b14 is fixed to the outside of the upper end of the stirring rod 12, and the bevel gear a13 is meshed with the bevel gear b14. The ultrasonic vibrator 15 is fixed to the end of the stirring rod 12 located inside the reaction tank 1, the electric slip ring 16 is installed at the upper end of the stirring rod 12, and the ultrasonic generator 17 is fixed to the upper end of the reaction tank 1. The ultrasonic vibrator 15 is electrically connected to the ultrasonic generator 17 through the electric slip ring 16, and the frequency modulation part 50 is electrically connected to the ultrasonic generator 17.

[0049] It should be noted that the common method for adjusting the frequency of ultrasound is to adjust the capacitance value or the resistance value, and the adjustment of the resistance value is more convenient. Different adjustment methods are adapted according to the design of the ultrasonic generating circuit. For example, in the NE555 time base circuit, the frequency is changed by adjusting the resistance value of the resistor. Different circuits can be used for the ultrasonic frequencies required in the activation reaction of chlorine dioxide with different stability. Among them, the ultrasonic generator 17 changes the ultrasonic frequency of the ultrasonic vibrator 15 by changing the resistance value. This is an existing mature technology known to those skilled in the art and will not be elaborated on here.

[0050] In this embodiment, during the activation reaction, the motor 11 is started to drive the bevel gear a13 to rotate, so that the bevel gear b14 follows the movement, which will drive the stirring rod 12 to rotate inside the reaction tank 1, thereby changing the position of the ultrasonic vibrator 15 inside the reaction tank 1. At the same time, the raw materials inside the reaction tank 1 can be stirred to accelerate the efficiency of the activation. Through the operation of the ultrasonic generator 17, the ultrasonic vibrator 15 emits ultrasonic waves, causing the liquid inside the reaction tank 1 to produce a cavitation effect, thereby promoting the reaction.

[0051] Second, see Figure 4 and Figure 5The liquid storage part 20 includes a tank body 21, an outer cover 22, a connecting tube 23, a transparent tube 24 and a pressurizing part 30. The transparent tube 24 is fixed to the upper end of the reaction tank 1, the connecting tube 23 is fixed to the upper end of the transparent tube 24, the dripping part 40 is installed on the connecting tube 23, the tank body 21 is fixed to the upper end of the connecting tube 23, the outer cover 22 is installed at the upper end of the tank body 21, and the pressurizing part 30 is installed at the lower end of the outer cover 22. The pressurizing part 30 is used to pressurize the liquid inside the liquid storage part 20.

[0052] It should be noted that the material of the transparent tube 24 is quartz glass. Through its stable corrosion resistance and transparency, the dripping speed of the liquid can be easily observed. At the same time, a photoelectric sensor is installed on the surface of the transparent tube 24 to increase the accuracy of monitoring the dripping speed of the liquid.

[0053] As described above, the outer cover 22 is separated from the tank body 21, liquid is added to the interior of the tank body 21, the pressurizing portion 30 is placed above the liquid inside the tank body 21, and then the outer cover 22 is installed on the tank body 21. Pressure is applied to the liquid through the pressurizing portion 30, so that the liquid passes through the connecting tube 23 and the transparent tube 24 and drips into the interior of the reaction tank 1, ensuring the stability of the dripping acceleration.

[0054] Secondly, please also refer to Figure 4 and Figure 5 The pressurizing part 30 includes a fixing rod 31, a compensation block 32, a compression spring 33 and a tension spring 34. The fixing rod 31 is fixed to the lower end of the outer cover 22, the compensation block 32 is slidably connected to the outside of the fixing rod 31, and the compensation block 32 is slidably connected to the tank body 21. The compression spring 33 is arranged on the outside of the fixing rod 31 and is located between the outer cover 22 and the compensation block 32. The tension spring 34 is arranged on the outside of the fixing rod 31 and is located below the compensation block 32. The upper end of the tension spring 34 is fixedly connected to the compensation block 32, and the lower end of the tension spring 34 is fixedly connected to the lower end of the fixing rod 31.

[0055] It is worth mentioning that a sealing ring is provided on the outside of the compensation block 32 to improve the sealing between the compensation block 32 and the tank body 21, to prevent the liquid from seeping out from the gap between the tank body 21 and the compensation block 32 when the compensation block 32 applies pressure to the liquid, and to ensure the stability of the pressure.

[0056] As mentioned above, during the process of liquid dripping inside the reaction tank 1, the compression spring 33 is in a compressed state, which will generate a downward thrust on the compensation block 32, and the tension spring 34 is in a stretched state, which will generate a downward pulling force on the compensation block 32, thereby causing the compensation block 32 to generate continuous pressure on the liquid inside the tank body 21, avoiding the reduction in the dripping speed due to the reduction in the weight of the liquid inside the liquid storage part 20, and ensuring the stability of the activation reaction.

[0057] Secondly, please refer to Figure 5The dripping part 40 includes an elastic porous part 41, a screw a42, an extrusion block 43 and a spring a44. The elastic porous part 41 is arranged inside the connecting tube 23, the screw a42 is threadedly connected to one side of the connecting tube 23, the extrusion block 43 is rotatably connected to one end of the screw a42 located inside the connecting tube 23, and the extrusion block 43 is slidingly connected to the connecting tube 23. The spring a44 is arranged inside the connecting tube 23 and is located between the elastic porous part 41 and the extrusion block 43.

[0058] It should be noted that the elastic porous member 41 is a sponge, and can also be other porous elastomers. Different materials can be selected according to different usage environments. The liquid can pass through the holes inside the elastic porous member 41 to produce water droplets, ensuring that the liquid drips into the interior of the reaction tank 1.

[0059] As mentioned above, when adjusting the dripping speed of the liquid inside the tank body 21, rotating the screw a42 will drive the extrusion block 43 to move inside the connecting tube 23, thereby changing the extrusion force generated by the extrusion block 43 on the spring a44, and then changing the elastic force generated by the extrusion force on the spring a44. By changing the degree of deformation of the elastic porous part 41 when it is squeezed by the spring a44, the permeability of the liquid inside the tank body 21 to the elastic porous part 41 can be changed, thereby changing the dripping speed of the liquid producing water droplets through the elastic porous part 41.

[0060] Secondly, please also refer to Figure 6 and Figure 7 The frequency modulation part 50 includes a fixing frame 51, an adjusting member 52, a connecting rod 53, a conductive contact 54, a spring b55, a conductive ball 56 and a fine-tuning member. The connecting rod 53 is fixed to the side of the extrusion block 43 away from the screw a42. The connecting rod 53 passes through the connecting tube 23 and the elastic porous member 41. The end of the connecting rod 53 away from the screw a42 is installed with the adjusting member 52. The fixing frame 51 is slidably connected to the outside of the adjusting member 52, and the adjusting member 52 is fixedly connected to the connecting tube 23. The conductive contact 54 is slidably connected to the inside of the fixing frame 51. The spring b55 is arranged inside the fixing frame 51, and the spring b55 is close to the end of the conductive contact 54 away from the adjusting member 52. The conductive ball 56 is ball-connected to the end of the conductive contact 54 close to the adjusting member 52. The fine-tuning member is arranged inside the adjusting member 52 and connected to the connecting rod 53.

[0061] It should be noted that the fine-tuning part is a screw b57, which is threadedly connected to the inside of the adjusting part 52, and the screw b57 is rotatably connected to the connecting rod 53. After the dripping part 40 adjusts the liquid dripping acceleration of the liquid storage part 20, it will drive the adjusting part 52 to move inside the fixed frame 51, change the position of the adjusting part 52, and then change the ultrasonic frequency of the ultrasonic part 10. By rotating the screw b57, the adjusting part 52 is driven to move inside the fixed frame 51, and then the ultrasonic frequency of the ultrasonic part 10 is adjusted again to improve the adjustment accuracy.

[0062] It is worth mentioning that the adjusting part 52 includes a resistance wire and an insulator, and the resistance wire is wound on the surface of the insulator, wherein one end of the resistance wire is electrically connected to the ultrasonic generator 17, and the conductive contact 54 is electrically connected to the ultrasonic generator 17. By changing the position of the conductive ball 56 on the insulator, the length of the resistance wire between the resistance wire at the contact position of the conductive contact 54 and the conductive ball 56 and the resistance wire connected to the ultrasonic generator 17 is changed, and then the resistance value of the resistance wire connected to the ultrasonic generator 17 is changed, thereby changing the ultrasonic frequency generated when the ultrasonic generator 17 controls the ultrasonic vibrator 15 to operate.

[0063] As mentioned above, when adjusting the dripping speed of the liquid, the length of the screw a42 inside the connecting tube 23 changes, which will drive the length of the connecting rod 53 inside the connecting tube 23 to change, so that the position of the adjusting member 52 inside the fixing frame 51 changes. During the movement of the adjusting member 52, the spring b55 always generates a thrust on the conductive contact 54, so that the conductive ball 56 is tightly attached to the surface of the adjusting member 52, ensuring that the conductive ball 56 always maintains electrical connection with the adjusting member 52 during the movement of the adjusting member 52, thereby improving the stability of the electrical connection.

[0064] The working principle of the present invention is as follows: raw materials for preparing chlorine dioxide disinfectant are added to the inside of the reaction tank 1, and liquid required for activation is added to the liquid storage part 20. When adjusting the activation reaction, the dripping part 40 is adjusted, and then the liquid dripping speed inside the liquid storage part 20 is adjusted, and at the same time, the frequency modulation part 50 is driven to follow the movement, so that the frequency modulation part 50 synchronously adjusts the ultrasonic frequency generated by the ultrasonic part 10, and can synchronously adjust the ultrasonic frequency while adjusting the liquid dripping speed, thereby improving the efficiency of the adjustment, avoiding the reaction instability caused by excessive deviation between the two due to adjustment, ensuring the efficiency of the activation, and reducing the tediousness of the work.

[0065] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
