Description

Technical Field

[0001] This utility model relates to the field of UV disinfection equipment technology, and more specifically to a food-grade UV disinfection equipment. Background Technology

[0002] UV disinfection equipment primarily utilizes specific wavelengths of ultraviolet light, especially the UVC band (wavelength 200-280nm), to destroy the genetic material of microorganisms. When UVC ultraviolet light irradiates bacteria, viruses, and other microorganisms, its high energy can penetrate the cell wall and directly act on the molecular structure of DNA or RNA, causing nucleic acid chains to break or cross-link, preventing the microorganisms from replicating and surviving, thus achieving highly efficient inactivation. Among these, ultraviolet light with a wavelength around 253.7nm has the highest sterilization efficiency.

[0003] For example, a UV disinfection device with prior art publication number CN221286374U is fixed to the side wall of a cabinet without an ultraviolet lamp by a hook. The UV disinfection box is placed on the hook. After pressing the power button, the items in the cabinet can be disinfected. The relative position of the UV disinfection box and the hook can be rotated to change the direction of the ultraviolet lamp on the UV disinfection box. The installation process is convenient and quick, without consuming a lot of manpower and time.

[0004] However, the aforementioned existing technologies still have the following problems in use: In the current market, many UV equipment chambers are made of 304 stainless steel, with substandard internal surface treatment, resulting in many unsanitary corners. Furthermore, the chambers have not undergone computer-aided fluid dynamics simulation, leading to uneven UV irradiation dosage and compromising the disinfection effect. Additionally, traditional UV equipment uses flange connections for inlet and outlet, which is unsuitable for the installation and rapid disassembly requirements of small-volume water treatment pipelines in the food and beverage industry. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a food-grade UV sterilization device that uses a clamp fixing method. Both clamps are composed of a ring-shaped metal clamp and a rubber sealing gasket to achieve connection. This connection method not only achieves the convenience of being weld-free and thread-free, but also allows installation to be completed in minutes without the use of any tools, ensuring a safe and smooth connection between the two parts, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a food-grade UV sterilization device, comprising a UV sterilizer body, a connecting pipe fixedly provided at one end of the UV sterilizer body, a detection pipe fixedly passing through the center of the front end of the UV sterilizer body, clamps fitted on the outer walls of both the connecting pipe and the detection pipe, the clamps comprising annular metal clamps, a rubber sealing gasket fixedly provided on the inner wall of the annular metal clamps, a first protective sleeve and a second protective sleeve respectively fitted on the outer wall of one end of the UV sterilizer body and the front end of the UV sterilizer body, two first sealing plates hinged to the side of the first protective sleeve away from the UV sterilizer body, and a second sealing plate hinged to the front end of the second protective sleeve.

[0007] In a preferred embodiment, rubber sealing strips are fixedly provided on the inner walls of both first sealing plates. The surface of the rubber sealing strips is in contact with the outer wall of the external pipe, which can effectively improve the sealing performance between the first sealing plates and the external pipe.

[0008] In a preferred embodiment, both the UV sterilizer body and the detection tube are made of stainless steel. Since stainless steel has the characteristics of corrosion resistance and easy cleaning, it can maintain hygiene. Therefore, as the material of the UV sterilizer body, it can effectively improve the cleanliness of the UV sterilizer body.

[0009] In a preferred embodiment, a strength sensor is inserted through the inside of the detection tube. The strength sensor is detachably fixed to the detection tube by a clamp and is located inside the second protective sleeve.

[0010] In a preferred embodiment, an annular groove is provided at the end of the connecting pipe away from the UV sterilizer body, and a rubber sealing ring is fixedly provided inside the annular groove. By providing a rubber sealing ring on the connecting surface of the connecting pipe, the rubber sealing ring can effectively improve the sealing performance of the two when the connecting pipe is connected to an external pipe.

[0011] In a preferred embodiment, an indicator arrow is fixedly provided at the front end of the UV sterilizer body. The indicator arrow is located on one side of the second protective cover, and the indicator arrow can help the staff to determine the direction of use.

[0012] In a preferred embodiment, the UV sterilizer body is provided with a quartz sleeve, which has a light transmittance of up to 87% or more, ensuring effective penetration of ultraviolet light and stable and effective sterilization.

[0013] The technical effects and advantages of this utility model are as follows: This utility model adopts a clamp fixing method to connect the connecting pipe and the external connecting pipe, the strength sensor and the detection pipe respectively. Both clamps are composed of annular metal clamps and rubber sealing gaskets to achieve connection. This connection method not only achieves the convenience of no welding and no threads, but also can be installed in a few minutes. Moreover, the overall structure is simple, and the installation and disassembly process is extremely simple. No tools are required to ensure a safe and smooth connection between the two parts.

[0014] The UV sterilizer body is made of food-grade stainless steel, which is corrosion-resistant and easy to clean, making it easy to maintain hygiene. The first and second protective sleeves protect the two clamps respectively, which can prevent the clamps from being hit and affecting the connection between the connecting pipe and the external pipe, and the connection between the detection pipe and the strength sensor, and can also improve the sealing performance to a certain extent.

[0017] 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.

[0018] Refer to the instruction manual appendix Figures 1-7 This utility model provides a food-grade UV disinfection device, including a UV disinfection body 1. A connecting pipe 2 is fixedly provided at one end of the UV disinfection body 1. A detection pipe 3 is fixedly passed through the center of the front end of the UV disinfection body 1. Both the connecting pipe 2 and the detection pipe 3 are fitted with clamps 4 on their outer walls. The clamps 4 include annular metal clamps 41. A rubber sealing gasket 42 is fixedly provided on the inner wall of the annular metal clamps 41.

[0019] An intensity sensor 10 is inserted inside the detection tube 3. The intensity sensor 10 works based on the photoelectric conversion principle. When ultraviolet light shines on the photosensitive element of the sensor, the photosensitive material absorbs the energy of ultraviolet photons and generates photocurrent or voltage changes. The sensor converts this physical signal into a quantifiable electrical signal (such as voltage, current or digital signal) through a circuit, which ultimately corresponds to the ultraviolet radiation intensity value. The intensity sensor 10 is detachably fixed to the detection tube 3 by a clamp 4. The intensity sensor 10 is located inside the second protective sleeve 6.

[0020] Both the main body 1 and the detection tube 3 of the UV sterilizer are made of stainless steel, such as 316L stainless steel. 316L stainless steel has strong corrosion resistance, good processing performance, balanced mechanical properties, and is hygienic and safe, so it is suitable for use in this device.

[0021] The main body 1 of the UV sterilizer is equipped with a quartz sleeve 14. The light transmittance of the quartz sleeve 14 is as high as 87% or above. Compared with the inferior traditional quartz sleeves 14 on the market, the light transmittance of the quartz sleeve 14 is high, which ensures that the ultraviolet rays can effectively penetrate and the sterilization is stable and effective.

[0022] In practical use, 316L stainless steel, which meets hygiene requirements and is food-grade, is used. Due to its corrosion resistance and easy cleaning properties, it maintains hygiene. Electrolytic polishing achieves an inner wall Ra≤0.8µm, and the inner and outer welds are ground cleanly without any dead corners. At the same time, clamps 4 are set on the main body 1 of the UV sterilizer to fix the external connecting pipe 2 and the strength sensor 10 connected to the connecting pipe 2. The two clamps 4 are connected by a combination of annular metal clamps 41 and rubber sealing gaskets 42, which can achieve the convenience of no welding and no threads. During installation, simply put the clamps 4 on the interface between the external pipe and the connecting pipe 2 and the outer wall of the detection pipe 3, and apply mechanical clamping force through the buckle on the annular metal clamp 41. The connection can be completed in a few minutes. The structure is simple, and the installation and disassembly are very simple. No tools are required to ensure a safe, smooth and uniform connection between the two parts.

[0023] Refer to the instruction manual appendix Figures 2-5The outer wall of one end of the UV sterilizer body 1 and the front end of the UV sterilizer body 1 are respectively fitted with a first protective sleeve 5 and a second protective sleeve 6. Two first sealing plates 7 are hinged to the side of the first protective sleeve 5 away from the UV sterilizer body 1. A second sealing plate 8 is hinged to the front end of the second protective sleeve 6. Rubber sealing strips 9 are fixedly provided on the inner walls of the two first sealing plates 7. The surface of the rubber sealing strips 9 is in contact with the outer wall of the external pipe.

[0024] By setting a first protective sleeve 5 and a second protective sleeve 6 at the two clamp positions 4 respectively, the first protective sleeve 5 and the two first sealing plates 7 cover the connection between the connecting pipe 2 and the external pipe, which can prevent the clamp 4 from being hit and affecting the connection between the connecting pipe 2 and the external pipe. The rubber sealing strips 9 on the inner wall of the two first sealing plates 7 are in contact with the surface of the external pipe, which can improve the sealing performance to a certain extent.

[0025] like Figure 7 As shown, the end of the connecting pipe 2 furthest from the UV sterilizer body 1 has an annular groove 11, and a rubber sealing ring 12 is fixedly installed inside the annular groove 11. By setting the rubber sealing ring 12 on the connecting surface of the connecting pipe 2, the rubber sealing ring 12 can effectively improve the sealing performance of the two when the connecting pipe 2 is connected to an external pipe.

[0026] Furthermore, an indicator arrow 13 is fixedly provided at the front end of the UV sterilizer body 1. The indicator arrow 13 is located on one side of the second protective sleeve 6. The indicator arrow 13 can help staff to determine the direction of use.

[0027] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
