Description

Technical Field

[0001] This utility model relates to the field of Chinese medicinal material production technology, and in particular to a device for eliminating Aspergillus flavus based on nano-far-infrared film thermal radiation. Background Technology

[0002] During the production and processing of Chinese medicinal materials, these materials are rich in active ingredients such as polysaccharides, proteins, and alkaloids, making them susceptible to microbial contamination. The growth of harmful microorganisms such as Aspergillus flavus can not only cause the medicinal materials to become moldy and rotten, but the toxins they produce can also seriously threaten the safety of medication. Currently, the mainstream sterilization technologies for Chinese medicinal materials include high-temperature dry heat sterilization and ultraviolet radiation sterilization, but all of them have obvious limitations. High-temperature sterilization can easily destroy the effective components of medicinal materials, chemical sterilization can easily leave harmful substances, and ultraviolet sterilization has weak penetration and is not thorough. Against this background, nano-infrared membrane radiation uses a nano-scale infrared radiation membrane as the core functional layer. By releasing far-infrared electromagnetic waves, it acts on the inside of cells and achieves excellent sterilization through thermal and non-thermal effects. Furthermore, most existing heating elements adopt a fixed installation structure, which is directly embedded in the inner wall of the casing or fixed to a non-movable support frame. During long-term use, they are prone to the adhesion of Chinese medicinal material fragments, dust and volatile organic residues, resulting in a decrease in sterilization efficiency and thus affecting the stability of sterilization effect. Because the heating element is installed in a concealed and fixed location, operators often need to disassemble multiple parts of the casing when cleaning and maintaining it. The operation process is cumbersome, time-consuming and labor-intensive, which not only increases the labor intensity of maintenance personnel, but also leads to excessive downtime for equipment maintenance, affecting production efficiency.

[0003] Therefore, it is necessary to design a nano-far-infrared film radiation sterilization device with convenient heating element cleaning and high maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of cleaning heating elements, and to propose a device for eliminating Aspergillus flavus based on nano-far-infrared film thermal radiation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for eliminating Aspergillus flavus based on nano-far-infrared film thermal radiation includes a frame, and a conveying mechanism is installed inside the frame; A housing, which is mounted on the top of the frame and hinged to the frame on one side; The frame is rotatably connected to the bottom of the housing; Multiple sets of carbon fiber heating tubes are arranged at equal intervals along the length of the conveying mechanism and fixed to the bottom of the frame. Each set of carbon fiber heating tubes has multiple tubes. A locking mechanism is used to lock the frame and housing, and the housing and frame. The locking mechanism includes two slides. Connecting seats are fixedly connected to the outer walls of both sides of the housing. The slide slides through the connecting seats on the same side, and a compression spring is sleeved on the outer wall of the slide. The two ends of the compression spring are fixedly connected to the connecting seats and the protrusions on the outer wall of the slide, respectively. Fixed seats II are fixedly connected to the outer walls of both sides of the housing. The bottom of the fixed seat II has a slot II. Fixed seats I are fixedly connected to the top two sides of the frame. The fixed seat I has a slot I. A rotating cylinder is rotatably sleeved on the outer wall of the slide. A locking plate is fixedly connected to the outer wall of the rotating cylinder. The locking plate can cooperate with slot I and slot II to lock or unlock.

[0006] In one possible design, the top of the card plate is set as a slope, which can guide the card plate to snap into card slot I or card slot II.

[0007] In one possible design, a handle is fixedly connected to the outer wall of the drum, and the operator can drive the drum to rotate and the carriage to slide up and down by holding the handle.

[0008] In one possible design, the locking mechanism further includes two L-shaped sliding plates, which are slidably connected to the inner sides of the frame. The frame surface has sliding holes for the L-shaped sliding plates to extend to the outside. The inner walls on both sides of the housing are fixedly connected to the card seats. The horizontal segments of the L-shaped sliding plates overlap the top of the card seats on the same side to achieve locking between the frame and the housing.

[0009] In one possible design, the locking mechanism further includes a connecting strip, which is fixedly connected to the side wall of the L-shaped slide and located inside the frame. One end of the slide is slidably inserted into a hole on the surface of the connecting strip to achieve linkage control of the locking mechanism.

[0010] In one possible design, a cylinder is rotatably connected to the side wall of the frame, and the end of the piston rod of the cylinder is rotatably connected to the side wall of the housing. After unlocking, the cylinder can drive the housing to flip upward, making it easier for the operator to access the frame.

[0011] In one possible design, the conveying mechanism is a conveyor belt.

[0012] In this application, when the Chinese medicinal materials are used, they are evenly spread on the conveying mechanism and conveyed to the tunnel cavity under the machine casing. After the device is powered on, the carbon fiber heating tube is turned on at the same time. The current passes through the nano carbon fiber membrane, the membrane heats up rapidly, and at the same time, far-infrared electromagnetic waves are released. The far-infrared rays penetrate the surface of the Chinese medicinal materials and are absorbed by the Aspergillus flavus on the surface and in the shallow layer of the medicinal materials, thereby killing the Aspergillus flavus. When cleaning the surface of the carbon fiber heating tube, the worker holds the holder and presses it downwards, which moves the slide downwards via the rotating cylinder. One end of the slide will disengage from the connector's insertion hole, and the retaining plate on the outer wall of the rotating cylinder will disengage from the retaining groove I. The rotating cylinder is then rotated so that the retaining plate rotates to below the fixing seat II. Then, the compression spring returns it upwards a certain distance, so that the retaining plate is locked inside the retaining groove II, thereby releasing the fixed connection between the frame and the housing. After releasing the fixed structures on both sides in the above steps, the cylinder can be driven so that its piston end drives the housing to flip open. After opening, the worker manually slides the L-shaped sliding plates on both sides so that the horizontal section disengages from the top of the holder, releasing the fixation between the frame and the housing. At this point, the frame can be held and rotated downwards to fall, thus exposing the multiple carbon fiber heating tubes on the surface for easy wiping and cleaning.

[0013] In this utility model, the device for eliminating Aspergillus flavus based on nano-far-infrared film thermal radiation can limit and fix the flip-open casing and the frame with carbon fiber heating tube installed through a locking mechanism, thereby ensuring the stability of the device during normal use. In this invention, the device for eliminating Aspergillus flavus based on the thermal radiation of a nano-far-infrared film uses a carbon fiber heating tube to allow current to pass through the nano-carbon fiber film, causing the film to heat up rapidly and release far-infrared electromagnetic waves. After the far-infrared radiation is absorbed by Aspergillus flavus, most of the energy is converted into heat energy, which raises the temperature of the mold cells and spores, thereby killing Aspergillus flavus on the surface of the Chinese medicinal materials. In this invention, when in use, the frame on which the heating element is installed can be flipped to one side of the device after the casing is opened, so that it is in an upright state. This makes it convenient for staff to wipe and perform other maintenance work, reducing the labor intensity during maintenance and improving maintenance efficiency. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In one embodiment: a sterilization device includes: a frame 1, a housing 2, a conveying mechanism 3, a carbon fiber heating tube 17, and a locking mechanism.

[0018] refer to Figure 1 The frame 1 is the main body of the device, and the conveying mechanism 3 is installed inside, preferably a conveying mesh belt, which is used to carry the materials to be sterilized, such as Chinese medicinal materials, and transport them to the sterilization area. The housing 2 is installed on the top of the frame 1, and one side is rotatably connected to the frame 1 through a hinge shaft. It can be flipped upward around the hinge shaft to expose the internal carbon fiber heating tube 17.

[0019] The casing 2 adopts a double-layer shell structure, with an interlayer between the inner and outer layers. The interlayer is filled with heat insulation material (such as aluminum silicate fiber, rock wool or aerogel felt) to reduce the heat loss of the carbon fiber heating tube 17 during operation and keep the temperature of the sterilization area inside the casing 2 within the set range.

[0020] refer to Figure 3 The bottom of the housing 2 is equipped with a frame 16 that rotates via a bearing. Multiple sets of carbon fiber heating tubes 17 are equidistantly arranged along the length of the conveying mechanism 3 at the bottom of the frame 16. Each set contains multiple parallel heating tubes to ensure uniform radiation to the material. When the carbon fiber heating tubes 17 are powered on, they release far-infrared rays that penetrate the surface of the material and kill microorganisms such as Aspergillus flavus through thermal and non-thermal effects.

[0021] The locking mechanism includes a first locking assembly for securing the housing 2 to the frame 1, and a second locking assembly for securing the frame 16 to the housing 2. refer to Figure 2The first locking component consists of two outer walls of the housing 2 with fixed connecting seats 11, a slide 9 that slides through the connecting seats 11, a compression spring 10 fitted on the outer wall, the two ends of the compression spring 10 being fixed to the protrusions of the connecting seats 11 and the slide 9 respectively, a rotating cylinder 12 being rotatably fitted on one end of the outer wall of the slide 9, a card plate 6 being fixed on the outer wall of the rotating cylinder 12, the top of the card plate 6 being a slope, a card slot 17 being opened at the bottom of the fixed seats I5 fixed on both sides of the top of the frame 1, and a card slot 214 being opened at the bottom of the fixed seats II13 fixed on the outer wall of the housing 2. During normal operation, the card plate 6 is inserted into the inside of the card slot I7 and is locked by the elastic force of the compression spring 10. When unlocking, press down on the slide 9 to disengage the card plate 6 from the inside of the card slot I7, thereby releasing the fixation of the housing 2, which can then be flipped open. After disengaging from the card slot I7, the card plate 6 rotates with the rotating drum 12 and is locked into the card slot II14.

[0022] refer to Figure 4-5 The second locking mechanism consists of an L-shaped sliding plate 20 slidably mounted on both sides inside the frame 16. A sliding hole 19 is provided on the surface of the frame 16 to allow the L-shaped sliding plate 20 to extend to the outside. A retaining bracket 18 is fixed to the inner walls of both sides of the housing 2. The horizontal segment of the L-shaped sliding plate 20 can be engaged with the top of the retaining bracket 18, thus locking the frame 16 to the housing 2. One end of the slide 9 is slidably inserted into the connecting strip 15's insertion hole inside the frame 16. The connecting strip 15 is fixedly mounted to the L-shaped sliding plate 20. When the device is in normal use and the first locking component is in the locked state, one end of the slide 9 will fix the L-shaped sliding plate 20 to ensure its stability. When the housing 2 is unlocked, the frame 16 is released simultaneously.

[0023] A cylinder 4 is rotatably mounted on the side wall of the frame 1. The piston rod end of the cylinder 4 is rotatably connected to the side wall of the housing 2. After unlocking, the cylinder 4 drives the housing 2 to flip upward, making it easier for the operator to access the frame 16.

[0024] The material is laid flat on the conveying mechanism 3 and enters the tunnel cavity below the housing 2. After the device is powered on, the carbon fiber heating tube 17 heats up and releases far-infrared rays, which penetrate the surface of the material to kill microorganisms such as Aspergillus flavus. The conveyor belt moves at a set speed to ensure that the material receives uniform radiation.

[0025] refer to Figure 6 When the carbon fiber heating tube 17 needs to be cleaned, press down on the slide 9 and rotate the drum 12 to disengage the card plate 6 from the slot I 7. After the spring 10 returns to its original position, the card plate 6 is inserted into the slot II 14, releasing the lock between the housing 2 and the frame 1. Then, start the cylinder 4 to flip the housing 2 and manually slide the L-shaped slide plate 20 to disengage it from the card seat 18. The frame 16 can then rotate downwards to expose the surface of the heating tube for easy wiping and cleaning.

[0026] This application can be used in the field of Chinese medicinal herb production, or in other fields applicable to this application.
