Description

Technical Field

[0001] The utility model relates to the field of human necessities, further to the field of sterilization and disinfection, especially to the field of ultraviolet sterilization, and particularly to a sterilizer for killing molds. Background Art

[0002] In traditional industries such as shoe-making, clothing-making, and toy-making, products are likely to carry various molds during production. If no sterilization treatment is carried out, the molds will multiply rapidly in a humid storage environment, affecting the personal safety of users. Therefore, most manufacturers will use sterilizers to perform sterilization treatment before the products leave the factory.

[0003] In the prior art, direct irradiation sterilization is usually carried out using ultraviolet rays with a wavelength of 253.7 nm. However, the sterilization effect is not good in the shaded areas not irradiated by ultraviolet rays. Therefore, ultraviolet rays with a wavelength of 185 nm are also used to generate ozone for sterilization. Since ozone has a toxic effect on the human nervous system, inhaling excessive ozone may cause adverse reactions such as dizziness and headache, endangering human health. Therefore, an ozone elimination device is also installed in the sterilizer.

[0004] However, there are still some unsolved problems in the prior art: 1. The elimination efficiency of the ozone elimination device is low, the air circulation in the sterilization channel is not smooth, it is difficult for the ultraviolet lamp tube to dissipate heat, and ozone is likely to accumulate and overflow; 2. The surface of the sterilized object in contact with the conveyor belt cannot fully contact ozone or be fully irradiated by ultraviolet rays, resulting in poor sterilization effect; 3. When the ultraviolet lamp tube is damaged, it is necessary to enter the sterilization channel for replacement and repair, which is inconvenient to operate. Summary of the Invention

[0005] The purpose of the utility model is to provide a sterilizer for killing molds, and the sterilizer for killing molds is to solve the technical problems such as low elimination efficiency of the overflowing ozone and easy inhalation of ozone when replacing and repairing the ultraviolet lamp in the prior art.

[0008] Further, the first sterilization device and the second sterilization device are respectively composed of at least two ultraviolet lamps. The ultraviolet lamps include ultraviolet lamps with a wavelength of 185 nm and ultraviolet lamps with a wavelength of 253.7 nm. The ultraviolet lamps with a wavelength of 185 nm and the ultraviolet lamps with a wavelength of 253.7 nm are arranged alternately.

[0009] Further, the conveyor belt is reticular.

[0010] Further, a reflective film is laid on the inner wall of the sterilization channel.

[0011] Further, the ozone elimination device includes a heating box. The air outlet of the second fan is communicated with the inlet of the heating box. The outlet of the heating box is communicated with the outside. At least one heating pipe is arranged in the heating box.

Detailed Embodiments

[0026] The following embodiments will further illustrate the present utility model, but do not limit the present utility model thereby.

[0027] Embodiment 1

[0028] As Figures 1 to 5 shown, this embodiment provides a sterilizer for killing mold, including a frame 1. A sterilization channel 2 is arranged through the front and back of the frame 1. A conveyor belt 3 is arranged in the sterilization channel 2, and the object to be sterilized is sent into the sterilization channel 2 through the conveyor belt 3 for sterilization; Protective curtains 11 are arranged at both the inlet and outlet ends of the sterilization channel 2 to shield ultraviolet light and ozone from overflowing from the sterilization channel 2.

[0029] At the top inside the sterilization channel 2, a first sterilization device 6 is provided. At the bottom inside the sterilization channel 2, a second sterilization device 7 is provided. The second sterilization device 7 is located below the conveyor belt 3. The first sterilization device 6 and the second sterilization device 7 are each composed of six ultraviolet lamps 12. The ultraviolet lamps 12 include ultraviolet lamps with a wavelength of 185 nm and ultraviolet lamps with a wavelength of 253.7 nm. The ultraviolet lamps 12 with different wavelengths are arranged alternately. The ultraviolet lamps with a wavelength of 185 nm can generate ozone. Utilizing the sterilization characteristics of ozone, the sterilization effect is achieved by the contact of ozone with the object to be sterilized. The ultraviolet lamps with a wavelength of 253.7 nm sterilize the object to be sterilized by direct irradiation.

[0030] Above the sterilization channel 2, a first fan 4 is provided. Below the sterilization channel 2, a second fan 8 is provided. The first fan 4 sucks the outside air into the sterilization channel 2, while the second fan 8 discharges the air inside the sterilization channel 2, thereby realizing the up-and-down circulation of air, enhancing the heat dissipation capacity of the ultraviolet lamp tubes, and at the same time discharging the ozone inside the sterilization channel 2 to avoid the accumulation of ozone in the sterilization channel 2.

[0031] At the air outlet of the second fan 8, an ozone elimination device 9 is provided. The ozone elimination device 9 includes a heating box 10. The heating box 10 is fixedly connected to the frame 1. The second fan 8 is connected to the top of the heating box 10. The second fan 8 includes two groups, and each group is composed of two side-by-side fans. Through the two groups of fans, the air inside the sterilization channel 2 can be discharged into the heating box 10. Corresponding to each group of the second fans 8, two side-by-side heating tubes 901 are provided below. After the heating tubes 901 are powered on, they are heated to at least 40 degrees, and the temperature of the air inside the heating box 10 rises. When the air containing ozone inside the sterilization channel 2 is discharged into the heating box 10 through the second fan 8, the ozone in the air is quickly eliminated by utilizing the characteristic that ozone decomposes rapidly when heated, and then is discharged to the outside through the grille at the bottom of the heating box 10, thereby realizing the effect of eliminating ozone.

[0032] At the top of the frame 1, a top cover 5 is provided. One side of the top cover 5 is hinged to the frame 1. The first fan 4 is provided on the top cover 5. By opening the top cover 5, the first fan can be quickly repaired or replaced, thereby improving the efficiency of repair or replacement.

[0033] The conveyor belt 3 is of a grid structure. When the object to be sterilized is placed on the conveyor belt 3, ozone and ultraviolet light can pass through the grid and contact the bottom surface of the object to be sterilized, thereby achieving an all-round sterilization effect.

[0034] The inner wall of the sterilization channel 2 is also lined with a reflective film, which increases the irradiation range through multiple reflections of ultraviolet light and further improves the sterilization effect.

[0035] The working principle of this embodiment:

[0036] During use, place the object to be sterilized on the conveyor belt and send it into the sterilization channel 2 in sequence for sterilization. Inside the sterilization channel 2, the ultraviolet lamps with a wavelength of 185 nm and the ultraviolet lamps with a wavelength of 253.7 nm are lit simultaneously. The ultraviolet lamps with a wavelength of 185 nm react with the air to generate ozone, and the sterilization is carried out by the contact of the ozone with the object to be sterilized. The ultraviolet lamps with a wavelength of 253.7 nm sterilize by direct irradiation. At the same time, the ultraviolet lamps with a wavelength of 253.7 nm are reflected by the reflective film laid on the inner wall of the sterilization channel 2 to sterilize the object to be sterilized from multiple angles, improving the sterilization range.

[0037] The first fan 4 sucks the outside air into the sterilization channel 2, while the second fan 8 discharges the air in the sterilization channel 2, so as to realize the up-and-down circulation of air, improve the heat dissipation ability of the ultraviolet lamp tube, and at the same time discharge the ozone in the sterilization channel 2 to the heating box 10 for decomposition and then discharge it to the outside, avoiding the accumulation of ozone in the sterilization channel 2.

[0038] When the air containing ozone in the sterilization channel 2 is discharged into the heating box 10 through the second fan 8, the ozone in the air is quickly eliminated by using the characteristic that ozone decomposes rapidly when heated, and then is discharged to the outside through the grille at the bottom of the heating box 10, so as to achieve the effect of eliminating ozone.

A blind hole is provided on the inner side wall of one side of the sterilization channel 2, and a through hole is provided on the side wall of the other side of the sterilization channel 2. One end of the ultraviolet lamp 12 passes through the through hole and is inserted and connected to the blind hole. A baffle is provided at the other end of the ultraviolet lamp 12, and the baffle is magnetically connected to the outer wall of the sterilization channel 2 on the side of the through hole. Pulling out the ultraviolet lamp 12 from the blind hole and the through hole can quickly realize replacement, improving the replacement efficiency of the ultraviolet lamp 12. A side cover plate is detachably provided on the frame, and contacts corresponding to the number of ultraviolet lamps 12 are installed on the side cover plate. A connector is provided on the side of the ultraviolet lamp 12 where the baffle 1201 is located. When the side cover plate is installed on the frame, these contacts are respectively electrically connected to the connectors corresponding to each ultraviolet lamp to supply power to the ultraviolet lamp 12.
