Description

Technical Field

[0001] This utility model relates to the field of polyvinylpyrrolidone production technology, and in particular to a sterilization device for polyvinylpyrrolidone production. Background Technology

[0002] Povidone, chemically known as polyvinylpyrrolidone (PVP), is a water-soluble polymer synthesized from N-vinylpyrrolidone (NVP) monomers via free radical polymerization. Since its first commercialization by BASF in Germany in 1939, it has become an indispensable key material in the pharmaceutical, cosmetic, food, industrial, and scientific research fields due to its excellent solubility, biocompatibility, film-forming properties, and chemical stability.

[0003] In the current production of povidone, chemical bactericides are generally used to sterilize the povidone. However, this may leave chemical residues, resulting in some harmful chemicals inside the povidone, which may affect human health. Utility Model Content

[0004] This invention provides a sterilization device for povidone production, which solves the structural technical problem mentioned above, where chemical bactericides are generally used to sterilize povidone, resulting in some harmful chemicals inside the povidone that may affect human health.

[0005] The present invention provides the following solution to the above-mentioned technical problems: A sterilization device for povidone production includes a sterilization tank. A driving stirring assembly is provided on the top of the sterilization tank. An air supply pipe is provided on the top of the sterilization tank. One end of the air supply pipe is connected to an ozone generator. A pipe support is provided on the outer wall of the air supply pipe. One side of the pipe support is connected to one side of the sterilization tank. A filter cylinder is provided near one side of the top of the sterilization tank. An absorption pipe is provided at the bottom of the filter cylinder. A first exhaust pipe is connected to the top of the filter cylinder. An air pump is installed at one end of the first exhaust pipe. A second exhaust pipe is provided at the discharge end of the air pump. An ozone catalytic decomposition device is provided at one end of the second exhaust pipe.

[0006] The beneficial effects of this invention are as follows: The sterilization tank mainly serves to facilitate the storage of povidone. The driving stirring component continuously stirs the povidone. The ozone generator ionizes oxygen molecules through a 5-20kV high-voltage electric field, decomposing them into oxygen atoms. These oxygen atoms combine with oxygen molecules to generate ozone, which destroys the cell wall / membrane structure of microorganisms through strong oxidation, killing bacteria, viruses, molds, yeasts, etc. This sterilizes the povidone. The gas supply pipe transmits ozone into the interior of the sterilization tank, and the pipe support facilitates the support of the gas supply pipe. The suction pipe allows the ozone inside the sterilization tank to be transported to the filter cartridge. The filter element inside the filter cartridge adsorbs ozone and also filters dust particles. The air pump can draw gas through the first exhaust pipe, and the second exhaust pipe can transport ozone to the ozone catalytic decomposition device. The ozone catalytic decomposition device efficiently decomposes ozone into oxygen through a catalyst-driven oxidation-reduction reaction.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the driving stirring assembly includes a speed-regulating motor, which is located at the top of the sterilization tank, and the output shaft of the speed-regulating motor is connected to an external permanent magnet.

[0009] The beneficial effects of adopting the above-mentioned further solution are: the speed-regulating motor can easily rotate the outer magnetic steel body permanent magnet. When the outer magnetic steel body rotates, its strong magnetic field will penetrate the sterilization tank and attract and drive the inner magnetic steel body permanent magnet inside the sterilization tank to rotate synchronously.

[0010] Furthermore, the sterilization tank is provided with an inner magnetic permanent magnet on its inner top surface, and a rotating column is connected to the bottom of the inner magnetic permanent magnet.

[0011] The beneficial effect of adopting the above-mentioned further scheme is that after the inner magnetic steel permanent magnet is rotated, it can carry the rotating column to rotate, and the rotating column can carry multiple stirring plates to rotate.

[0012] Furthermore, multiple stirring plates are arranged in a linear equidistant array on both sides of the rotating column, and two flow ports are provided on one side of each stirring plate.

[0013] The beneficial effects of adopting the above-mentioned further solution are: multiple stirring plates can agitate the polyvinyl chloride inside the sterilization tank, the flow port can reduce the flow resistance of agitation, and also facilitate the reduction of material adhesion on the surface of the stirring plates.

[0014] Furthermore, the top of the sterilization tank is provided with a feed inlet, and the bottom of the sterilization tank is provided with a discharge outlet.

[0015] The advantages of adopting the above-mentioned further solution are: the inlet allows povidone to be poured into the sterilization tank, and the discharge port allows the sterilized povidone to be discharged easily.

[0016] Furthermore, a mounting plate is connected to one side of the air pump, and one side of the mounting plate is connected to the other side of the sterilization tank.

[0017] The advantage of adopting the above-mentioned further solution is that the mounting plate can easily support one side of the air pump, which can improve the stability of the connection.

[0018] Beneficial effects: The ozone generator allows ozone to enter the sterilization tank through the gas supply pipe. The driving stirring component inside continuously stirs the ozone, ensuring that the povidone is fully exposed to the ozone. This replaces the process of using chemical disinfectants, eliminating chemical residues. The ozone can be processed by the ozone catalytic decomposition device, preventing harmful chemicals from affecting human health within the povidone.

[0022] The following is in conjunction with the appendix Figure 1-3 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. Example

[0023] like Figure 1-3 As shown, this utility model discloses a sterilization device for povidone production, comprising a sterilization tank 1, a driving stirring assembly 2 at the top of the sterilization tank 1, a gas supply pipe 3 at the top of the sterilization tank 1, an ozone generator 4 connected to one end of the gas supply pipe 3, a pipe support 5 on the outer wall of the gas supply pipe 3, one side of the pipe support 5 connected to one side of the sterilization tank 1, a filter cylinder 6 near one side of the top of the sterilization tank 1, a suction pipe 7 at the bottom of the filter cylinder 6, a first exhaust pipe 8 connected to the top of the filter cylinder 6, an air pump 9 installed at one end of the first exhaust pipe 8, a second exhaust pipe 10 at the discharge end of the air pump 9, and an ozone catalytic decomposition device 11 at one end of the second exhaust pipe 10. Example

[0024] like Figure 1-3 As shown, the driving stirring assembly 2 includes a speed-regulating motor 21, which is located at the top of the sterilization tank 1. The output shaft of the speed-regulating motor 21 is connected to an outer permanent magnet 22. An inner permanent magnet 221 is provided on the inner top surface of the sterilization tank 1. A rotating column 23 is connected to the bottom of the inner permanent magnet 221. Multiple stirring plates 24 are arranged linearly and equidistantly on both sides of the rotating column 23. Two flow ports 25 are provided on one side of each stirring plate 24.

[0025] In this embodiment, the speed-regulating motor 21 can easily rotate the outer permanent magnet 22. When the outer permanent magnet rotates, its strong magnetic field will penetrate the sterilization tank 1, attracting and driving the inner permanent magnet 221 inside the sterilization tank 1 to rotate synchronously. After being rotated, the inner permanent magnet 221 can rotate the rotating column 23. The rotating column 23 can rotate multiple stirring plates 24. The multiple stirring plates 24 can agitate the polyvinyl chloride inside the sterilization tank 1. The flow port 25 can reduce the flow resistance of the agitation and also help reduce the adhesion of materials on the surface of the stirring plates 24. Example

[0026] like Figure 1-3As shown, the top of the sterilization tank 1 is provided with a feed inlet 12, the bottom of the sterilization tank 1 is provided with a discharge outlet 13, and one side of the air pump 9 is connected to a mounting plate 14, and one side of the mounting plate 14 is connected to the other side of the sterilization tank 1.

[0027] In this embodiment, the feed port 12 facilitates the pouring of povidone into the sterilization tank 1, the discharge port 13 facilitates the discharge of sterilized povidone, and the mounting plate 14 facilitates the support of one side of the air pump 9, thereby improving the stability of the connection.

[0028] Working principle: When povidone needs to be sterilized, first open the inlet 12 on the sterilization tank 1 to allow povidone to enter the tank. After closing the inlet 12, start the ozone generator 4. The ozone generator 4 uses a 5-20kV high-voltage electric field to ionize oxygen molecules, breaking them down into oxygen atoms. These oxygen atoms combine with oxygen molecules to generate ozone, which can then enter the sterilization tank 1 through the gas delivery pipe 3. This causes the speed-regulating motor 21 to rotate the outer permanent magnet 22. As the outer permanent magnet 22 rotates, its strong magnetic field penetrates the sterilization tank 1, attracting and driving the inner permanent magnet 221 to rotate synchronously. The inner permanent magnet 221 then rotates the rotating column 23 and the stirring plate 24. The stirring plate 24 facilitates the agitation of the povidone, and the flow port 25 helps reduce flow resistance and minimizes residue buildup on the surface of the stirring plate 24. The material adheres, allowing povidone to move through and be fully contacted by ozone, thus replacing the process of using chemical disinfectants for sterilization. This eliminates chemical residues. The ozone can be treated by the ozone catalytic decomposition device 11, preventing harmful chemicals from affecting human health inside the povidone. After sterilization, the suction of the air pump 9 allows the suction tube 7 to pass the ozone inside the sterilization tank 1 through the filter cartridge 6. The filter element inside the filter cartridge 6 can sieve dust particles in the ozone and also adsorb some ozone. The first exhaust pipe 8 on the filter cartridge 6 can be connected to the air pump 9, and the second exhaust pipe 10 can transport the ozone into the ozone catalytic decomposition device 11. The ozone catalytic decomposition device 11 efficiently decomposes ozone into oxygen through a catalyst-driven oxidation-reduction reaction. The catalyst surface has highly active sites, which change the electron cloud distribution of ozone molecules by adsorbing them, causing bond breaking and recombination in the ozone. For example, the porous structure of activated carbon can enrich ozone, and the electron transfer triggered by surface functional groups can decompose O3 into O2; metal oxides can activate ozone through lattice oxygen migration, reduce the reaction activation energy, and achieve efficient decomposition at room temperature.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
