Description

Microwave disinfection and sterilization device for securities

Technical field

The invention relates to a microwave disinfection and sterilization device for valuable securities, belonging to the technical field of disinfection.

Background technique

A large number of bacteria, viruses and parasites are attached to the securities in circulation. Once these bacteria, viruses and parasites are spread, infected or parasitic in the human body, the adverse effects on human health are very large. Therefore, it is very necessary to disinfect and sterilize the securities. Especially for some viruses that are extremely contagious and cause great harm to the body, it is of positive significance to prevent the spread of viruses and bacteria through disinfection and sterilization devices.

At present, there are mainly three methods for disinfection and sterilization of securities: first, disinfection by ultraviolet light; second, disinfection by heating; and third, disinfection by microwave. Among them, microwave disinfection and sterilization has strong penetrating power, and has a good antivirus and sterilization effect on viruses and bacteria attached to securities.

In the Chinese patent document with the publication number CN 2241545Y, a low-temperature-rise microwave sterilization and sterilization device is disclosed, which includes a microwave source and a microwave sterilization box. Among them, the microwave source is a microwave source that radiates microwaves intermittently, and the microwave radiation frequency is 640 MHz to 2160 MHz; the microwave sterilization box is surrounded by copper or aluminum plates.

However, the above-mentioned microwave is an electromagnetic wave. Metal conductors will produce electromagnetic induction in microwaves, and the electric charges will be redistributed on the surface of the conductors, thereby generating a potential difference. If the potential difference is large enough, it may break down the air and ionize the air to produce sharp discharges, sparks or even arcs. In order to enhance its anti-counterfeiting performance, securities will add optical characteristic materials, magnetic characteristic materials and electrical characteristic materials. The direct use of microwave technology to sterilize these securities will damage their face printing features and machine-readable anti-counterfeiting performance, and in severe cases will cause the securities to be carbonized or burned.

The bottom plate 82 of the box 8 serves as the second baffle 5. The top plate 81 and the bottom plate 82 are respectively made of microwave non-permeable materials, and are fixedly arranged in the frame of the containing box 8.

In order to achieve non-mixed mode electromagnetic waves, the height of the space in the single containing box 8 (ie, the length in the direction of the smaller size) can meet specific conditions, such as not greater than half the microwave wavelength, or less than 0.3 times the microwave wavelength.

Of course, it is also possible to make the height of the single receiving box 8 (that is, the length in the smaller size direction) larger, and by providing one or more partitions 9 between the top plate 81 and the bottom plate 82, the partition 9 will hold the box The internal space of 8 is divided into a plurality of small chambers whose height h meets the above-mentioned conditions. The partition 9 is made of microwave non-permeable material. The partition 9 serves as the first baffle 4 and the second baffle 5 at the same time, so that the height of the multiple small chambers is not greater than half the microwave wavelength or less than 0.3 times the microwave. Under the condition of the wavelength, the electromagnetic wave of the non-mixed mode is realized. Each small chamber constitutes a security holding area 10.

As shown in Figure 5, the frame and side panels of the receiving box 8 can be made of plastic, and multiple holes can be provided on at least one side panel. On the one hand, the weight of the receiving box 8 can be reduced. Each hole is used as a vent hole for the emission of moisture during the microwave disinfection and sterilization process.

In the above embodiment, taking the horizontal placement of the securities 2 as an example, various implementations of the securities holding area 10, the first baffle 4, and the second baffle 5 are illustrated. It can be understood that in other embodiments not shown in the figure, the securities 2 can be placed vertically inside the microwave working cavity 1. At this time, the first baffle 4 and the second baffle 5 are perpendicular to the bottom plate of the microwave working cavity 1. 12 setting, the first baffle 4 and the second baffle 5 can also be wall plates of the microwave working cavity 1, or a baffle arranged inside the microwave working cavity 1, or independently arranged inside the microwave working cavity 1. Of the bezel. In the same way, for the case where the containing box 8 is provided inside the microwave working cavity 1, the containing box 8 can also be rotated 90 degrees and placed inside the microwave working cavity 1, so that the securities 2 are vertically placed in the microwave working cavity 1. internal.

In order to determine what conditions the distance between the first baffle 4 and the second baffle 5 meets, the non-mixed mode microwave can be obtained in the securities holding area 10 between the two baffles. The applicant uses common The microwave sterilization parameters of the experiment were conducted for different wavelengths and different baffle spacing. Get the conclusion shown in Table 1.

Table 1 Summary of experimental results where wavelength and baffle spacing meet different conditions

Experiments have proved that for the different wavelengths used in the experiment (for example, f=2450MHz, λ=122mm; f=915MHz, λ=328mm), when the distance h between the two baffles is not greater than the microwave half-wavelength, it is 180 seconds During the test period of, none of the securities were carbonized or burned. When the distance h between the two baffles is greater than the half-wavelength of the microwave, even if it is heated for a short time, the securities will be carbonized and burnt, and the shortest ignition time is no more than 3 seconds. Experiments with different wavelengths can get the same experimental results. The above experimental results not only verify the effectiveness of arranging the first baffle and the second baffle on both sides of the securities holding area, but also verify the effectiveness of arranging the first baffle and the second baffle in the microwave working cavity. Necessity, the use of the first baffle and the second baffle can fundamentally change the microwave environment of the securities holding area and avoid the phenomenon of carbonization and burning of the securities.

In addition, the applicant uses the securities microwave disinfection and sterilization equipment provided by the embodiment of the present invention to sterilize and sterilize different securities, and use the ATP fluorescent bacteria monitor to perform the disinfection and sterilization of the securities before and after the treatment. Bacteria detection.

Table 2 Summary of bacterial detection results of different securities after microwave treatment

It can be seen from Table 2 that the use of microwave for disinfection and sterilization of securities, as the microwave treatment time increases, the sterilization effect gradually increases. When the microwave treatment time reaches 60 seconds, there is little difference in the sterilization effect, that is, It is said that a sterilization time of 60 seconds can already achieve a good sterilization effect, while the improvement of the sterilization effect by a longer time of sterilization is limited. It can be seen from Table 1 that the use of the first baffle 4 and the second baffle 5 to protect the securities holding area 10 can ensure that the securities 2 will not be carbonized or burnt during the entire sterilization time.

In summary, the microwave sterilization and sterilization device for securities provided by the embodiment of the present invention is configured to provide baffles made of microwave non-permeable materials on both sides of each securities storage area, and set them at The distance between the two layers of baffles on both sides of the same securities holding area and the microwave wavelength meet the predetermined proportional relationship, which can realize non-mixed mode electromagnetic waves, and can avoid the optical characteristic materials, magnetic characteristic materials and electrics in the securities.
