[0002] Industrial microwave equipment combined with steam sterilization is an efficient sterilization method, usually referred to as a microwave-steam combined sterilization system.

[0025] Please refer to Figures 1 to 3 A low-cost sensing structure for microwave equipment includes an outer barrel 11, an isolation inner sleeve 12 fixedly arranged in the outer barrel 11, at least one communication sensor 30, and at least one microwave generator 13 installed on the outer side wall of the outer barrel 11. The outer barrel 11 can form a closed space. The bottom of the isolation inner sleeve 12 extends downward to the inside of the outer barrel 11 to isolate the bottom space between the isolation inner sleeve 12 and the outer barrel 11. The inner side of the isolation inner sleeve 12 is used to place the object to be microwave treated. The outer barrel 11 is provided with a one-to-one connection sensor 30 and a microwave generator 13. The corresponding openings are used for microwaves to pass through, so that the microwaves radiate toward the isolation inner sleeve 12; the material of the isolation inner sleeve 12 in the area where the microwaves are radiated is high borosilicate; the connecting sensor 30 includes a liquid heat-conducting part 31 and a temperature sensor 32 connected to each other, and the liquid heat-conducting part 31 contains a heat-conducting liquid that contacts the sensing part of the temperature sensor 32, and the liquid heat-conducting part 31 is arranged in the space between the isolation inner sleeve 12 and the outer barrel 11 to realize that the microwaves pass through the isolation inner sleeve 12 to heat the heat-conducting liquid, and the temperature sensor 32 is arranged outside the outer barrel 11.
[0026] The closed outer barrel 11 is divided into an inner and outer space by setting an isolating inner sleeve 12 made of high borosilicate material. On the one hand, the liquid heat-conducting part 31 connected to the sensor 30 is set between the isolating inner sleeve 12 and the inner wall of the outer barrel 11, so as to utilize the microwave-transmissive, high heat-resistant and high mechanical strength properties of high borosilicate to heat the heat-conducting liquid in the liquid heat-conducting part 31 with microwaves; on the other hand, the temperature sensor 32 is set outside the outer barrel 11, and the metal material properties of the outer barrel 11 are utilized for heat insulation and microwave insulation to ensure that the temperature sensor 32 is not interfered with, so as to realize the temperature collection of the heat-conducting liquid through the temperature sensor 32, and cleverly realize the detection of the temperature in the barrel, so as to accurately adjust and control the relevant parameters of the microwave treatment based on the temperature, and ensure the microwave treatment effect.
[0027] Please refer to Figure 2 and Figure 3 The connecting sensor 30 is U-shaped, and the liquid heat conducting part 31 includes a connecting piece 311 and a heat conducting liquid storage piece 312. The connecting piece 311 is arranged across the outer barrel 11. The U-shaped shape can effectively set the temperature sensor 32 and the heat conducting liquid storage piece 312 on both sides of the side wall of the outer barrel 11 respectively. At the same time, the principle of the U-shaped communicating vessel is utilized to realize the temperature transfer from the inside of the barrel to the outside of the barrel through the setting of the connecting piece 311, thereby cleverly realizing temperature collection.
[0028] For further information, please refer to Figure 3The connecting member 311 includes a horizontal fixed tube and connecting elbows respectively connected to both ends of the horizontal fixed tube. One of the connecting elbows is connected to the thermal liquid storage member 312 through a first adapter; the other connecting elbow is connected to the temperature sensor 32 through a second adapter. By fixing the horizontal fixed tube on the side wall of the outer barrel 11 in advance, the subsequent installation of the two connecting elbows and the adapter is facilitated.
[0029] Furthermore, the thermal liquid storage component 312 is tubular, used to pour the thermal liquid from the outside, and at the same time guide the thermal liquid along the adapter, the connecting elbow, the horizontal fixed tube, etc. to contact the sensing part of the temperature sensor 32. The first adapter is hollow and convex, and both ends are provided with internal threads for detachable connection with the connecting elbow and the thermal liquid storage component 312 respectively; the second adapter is in the middle and convex, and both ends are provided with internal threads for detachable connection with another connecting elbow and the temperature sensor 32 respectively; the multi-component detachable structure can effectively achieve the subsequent use in high temperature and microwave environments. Once any component is damaged, it can be quickly replaced. The overall structural design is simple and easy to replace, which can effectively reduce the subsequent use cost.
[0030] In addition, the heat transfer fluid is oil (such as diesel, kerosene, rapeseed oil, gasoline, etc.). Since the temperature inside the microwave equipment is often higher than 100 degrees, if water is used, the heat transfer fluid will be insufficient due to evaporation. The high boiling point of oil can effectively adapt to this application scenario. Other conventional high-boiling point heat transfer fluids can also be used.
[0031] Please refer to Figure 1 and Figure 2 The isolation inner sleeve 12 is tubular and made of high borosilicate. The tubular sleeve can effectively adapt to the shape of the outer barrel 11 and the scene of re-crushing the processed materials in the barrel, which is convenient for the rotation of the crushing blade and ensures that enough processed materials can be stored in the sleeve. The whole is made of high borosilicate material, which can also make the whole internal heating more uniform and the heat transfer effect better.
[0032] Furthermore, the distance from the top of the isolation inner sleeve 12 to the top of the outer barrel 11 ranges from 3cm to 10cm; preferably, the distance is 5cm. At the same time, a reasonable distance setting ensures that it will not be too close to the top to affect the opening and closing of the cover of the outer barrel 11, and the height of the isolation inner sleeve 12 ensures that the microwave can be completely transparent; the distance from the side wall of the isolation inner sleeve 12 to the side wall of the outer barrel 11 ranges from 4cm to 8cm, and preferably, the distance is 4cm. Through appropriate spacing, it is avoided that the spacing is too large to accommodate insufficient space for the processed material, and it is also avoided that the spacing is too small to limit the setting position of the connecting sensor 30; the ratio of the distance from the bottom of the isolation inner sleeve 12 to the bottom of the outer barrel 11 to the height of the outer barrel 11 is 0.2 to 0.4, and preferably, the ratio is 0.3. Through the setting of this ratio, the amount and area of high borosilicate can be effectively controlled, which not only ensures the use requirements of microwave transparency, but also reduces costs as much as possible and avoids direct contact with the crushing blade and damage.
[0033] Please refer to Figure 1 The number of the microwave generators 13 is at least four. By using a plurality of evenly arranged microwave generators 13 in conjunction with an isolating inner sleeve 12 made of high borosilicate material at a corresponding position, the barrel can be effectively heated evenly. The number of the communication sensors 30 is at least four. Preferably, the number of the communication sensors 30 is eight. The microwave generators 13 are distributed on the outer wall of the outer barrel 11 and are all located within the height range of the isolating inner sleeve 12. The communication sensors 30 are distributed on the side wall of the outer barrel 11, generally divided into two groups, each with four evenly distributed, and staggered between each group to detect the temperature of each part of the barrel as a whole and ensure the microwave heating effect.
[0034] The microwave generator 13 is a prior art, which is composed of multiple microwave heating components, including a microwave switching power supply, a magnetron, a rectangular waveguide, etc. It can be directly purchased on platforms such as 1688 by searching for keywords such as related industrial microwave drying equipment components or industrial microwave heating equipment components, and will not be elaborated here.
[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
