It includes the main body of the device, an internal drying and sterilization chamber equipped with a microwave emission source or hot air circulation system, and a stepped conveyor belt. Items are placed on the conveyor belt, and as the belt moves, the items rise or fall step by step within the drying and sterilization chamber, achieving comprehensive and thorough drying and sterilization. During operation, this device can not only dry items using microwaves or hot air, but also sterilize them using microwaves or high temperatures. During the drying or sterilization process, the internal space of the drying and sterilization chamber can be ventilated by forced draft or exhaust, providing a circulating airflow environment for a more efficient drying process.
[0003] In the prior art, a stepped transfer method is usually used to extend the drying time and improve the drying and sterilization effect during the drying and sterilization process. However, during the transfer of materials inside the device, there is often an accumulation phenomenon, which can easily lead to a decrease in the drying and sterilization effect. Therefore, those skilled in the art have provided a stepped drying and sterilization device to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stepped drying and sterilization device. This device achieves pre-treatment drying and sterilization through a pre-treatment mechanism, thereby improving the sterilization effect. Furthermore, once the material enters the drying mechanism, the conveyor belt prevents material accumulation, further enhancing the drying and sterilization effect.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A stepped drying and sterilization device includes a drying mechanism, a hot air blower fixedly installed at the rear end of the drying mechanism, upper connecting frames fixedly installed on both sides of the drying mechanism near the upper end, a pretreatment mechanism installed between the two upper connecting frames, a sealing frame fixedly installed between the pretreatment mechanism and the drying mechanism, the pretreatment mechanism including two rotating frames, a hollow shaft rotatably installed at the internal center of one of the two rotating frames, and a treatment tank rotatably installed at the internal center of the other of the two rotating frames;
[0007] The drying mechanism includes a lower support frame, a wobbling motor fixedly mounted on one side of the lower support frame, and two power shafts rotatably mounted between the two sides inside the lower support frame. One of the two power shafts, the one closer to the wobbling motor, is connected to the output end of the wobbling motor. An eccentric disc is fixedly mounted on the opposite side between the two power shafts, and an inner support frame is fixedly mounted between the two eccentric discs. Four conveyor belts are staggered inside the inner support frame, and a feeding plate is inserted through the lower front end of the lower support frame.
[0008] Furthermore, a central columnar protrusion on one side of the treatment tank is rotatably disposed at the inner center of one of the two rotating frames, and a hollow cover is threaded onto the other side of the treatment tank. A perforated mesh is snapped onto the inner side of the hollow cover. The hollow shaft is rotatably disposed through the hollow cover and the center of the perforated mesh at the other position of the two rotating frames, and one end of the hollow shaft is rotatably disposed inside the cylindrical groove at the center of the inner wall on one side of the treatment tank.
[0009] Furthermore, the hollow shaft body is uniformly rotated and sleeved with three rotating rings in sequence. The outer ring surfaces of the three rotating rings are each centrally symmetrically fixed with three hammer rods. The outer ends of the nine hammer rods are all fixedly set to the inner wall of the treatment tank. Multiple liquid outlet holes are centrally symmetrically opened on both sides of the hollow shaft body near the middle position.

[0015] 1. The present invention proposes a stepped drying and sterilization device. When the material enters the drying mechanism, the device first drives the power shaft to rotate by a shaking motor. Then, the power shaft drives the inner support frame and the conveyor belt to rotate eccentrically through the eccentric disc. At this time, the material falling on the conveyor belt will be moved and turned over by the conveyor belt, thus avoiding the accumulation of material and improving the drying and sterilization effect.
[0016] 2. This utility model proposes a stepped drying and sterilization device. Through multiple liquid outlet holes in the hollow shaft, the device not only achieves pre-treatment drying and sterilization, improving the sterilization effect, but also allows for the addition of auxiliary materials during the process, facilitating subsequent cleaning and maintenance.

Detailed Implementation
[0024] 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.
[0025] Reference Figure 1 and 2 An embodiment of this utility model is provided: a stepped drying and sterilization device, including a drying mechanism 4, a hot air blower 5 fixedly installed at the rear end of the drying mechanism 4, upper connecting frames 2 fixedly installed on both sides of the drying mechanism 4 near the upper end, a pretreatment mechanism 1 installed between the two upper connecting frames 2, a sealing frame 3 fixedly installed between the pretreatment mechanism 1 and the drying mechanism 4, the pretreatment mechanism 1 including two rotating frames 109, a hollow shaft 101 rotatably installed at the internal center of one of the two rotating frames 109, and a treatment tank 108 rotatably installed at the internal center of the other of the two rotating frames 109;
[0026] Specifically, the output end of the hot air blower 5 is connected to the air pipe structure on the pretreatment mechanism 1 through a pipe, which can deliver hot air into the device to achieve the function of hot air drying and sterilization. By setting the pretreatment mechanism 1, not only is pretreatment drying and sterilization achieved, improving the sterilization effect, but auxiliary materials can also be added during the process, which is also convenient for later cleaning and maintenance.
[0027] Reference Figure 4 and 5The drying mechanism 4 includes a lower support frame 404. A vibrating motor 410 is fixedly installed on one side of the lower support frame 404. Two power shafts 405 are rotatably installed between the two sides inside the lower support frame 404. One of the two power shafts 405, closer to the vibrating motor 410, is connected to the output end of the vibrating motor 410. An eccentric disc 406 is fixedly installed on opposite sides between the two power shafts 405. An inner support frame 401 is fixedly installed between the two eccentric discs 406. Four conveyor belts 407 are staggered inside the inner support frame 401. A feeding plate 411 is installed through the lower front end of the lower support frame 404. The side of the inner support frame 401 furthest from the vibrating motor 410 is fixedly installed... Two power motors 402 are fixedly installed. Two transmission discs 409 are rotatably installed on the side of the inner support frame 401 away from the shaking motor 410. The two transmission discs 409 and the two power motors 402 are connected to the transmission belts 403 through pulleys. The four pulleys are respectively fixedly connected to the internal shafts of the four transmission belts 407. Stable slide rods 408 are fixedly installed between the two sides inside the inner support frame 401. Stable slide grooves 412 are opened on the upper part of both sides of the inner support frame 401. The two stable slide rods 408 are slidably installed inside the two stable slide grooves 412. The output end of the shaking motor 410 is connected to the hollow shaft 101 through pulleys and belts.
[0028] Specifically, when the material enters the drying mechanism 4, the sterilization device first drives the power shaft 405 to rotate via a shaking motor 410. Subsequently, the power shaft 405, through the mechanical action of an eccentric disc 406, further drives the inner support frame 401 and the conveyor belt 407 to rotate eccentrically. During this process, the material falling onto the conveyor belt 407 is simultaneously moved and tumbled by the conveyor belt. This design effectively avoids material accumulation during the drying process, thereby significantly improving the drying and sterilization effect.
[0029] Reference Figure 1-3A cylindrical protrusion at the center of one side of the treatment tank 108 is rotatably mounted to the center of one of the two rotating frames 109. A hollow cover 102 is threaded onto the other side of the treatment tank 108, and a perforated mesh is snapped into the inner side of the hollow cover 102. A hollow shaft 101 is rotatably mounted near the other position of the two rotating frames 109, penetrating and rotating to the center of the hollow cover 102 and the perforated mesh. One end of the hollow shaft 101 is rotatably mounted inside a cylindrical groove at the center of the inner wall of one side of the treatment tank 108. Three rotating rings are sequentially and evenly mounted on the shaft of the hollow shaft 101. 105. Three hammer rods 104 are fixedly and centrally symmetrically installed on the outer ring surface of the three rotating rings 105. The outer ends of the nine hammer rods 104 are fixedly installed to the inner wall of the treatment tank 108. Multiple liquid outlet holes 106 are centrally and symmetrically opened on both sides of the hollow shaft 101 near the middle position. A threaded joint is fixedly installed at one end of the hollow shaft 101 opening. A feed inlet 107 is fixedly installed through the middle position of the upper and lower ends of the treatment tank 108. Four air pipe interfaces 103 are centrally and symmetrically fixedly installed through the outer side of the hollow cover 102.
[0030] Specifically, the design of multiple liquid outlet holes 106 in the hollow shaft 101 and the hammer rod 104 not only achieves pretreatment, drying, and sterilization of materials, thus significantly improving the sterilization effect, but also allows for the convenient addition of various auxiliary materials during the process. This design also greatly facilitates subsequent cleaning and maintenance. After use, the user can easily connect a high-pressure water source to the hollow shaft 101 and then start the second motor to drive the processing tank 108. By using these liquid outlet holes 106 for spraying, the inside of the shaft and the tank can be thoroughly cleaned, greatly improving cleaning efficiency. In addition, the perforated mesh design effectively prevents material from splashing during processing and avoids material entering the air pipe interface 103 and causing blockage. This not only reduces the difficulty and frequency of maintenance but also makes the maintenance of the entire device simpler. These advantages work together to help extend the service life of the equipment.
[0031] Working principle: During use, materials are fed into the tank through the inlet 107 according to actual needs. The air inside the tank is effectively extracted through the perforated mesh by one or more of the four air pipe interfaces 103 on the outside of the hollow cover 102 using an external vacuum device. The perforated mesh effectively prevents materials from splashing into the air pipe interfaces 103 and causing blockage. Then, the shaking motor 410 is started, which drives the central columnar protrusion on one side of the treatment tank 108 to rotate. One end of the hollow shaft 101 is rotatably set inside the cylindrical groove in the center of the inner wall of one side of the treatment tank 108, and the other end of the shaft is rotatably set inside the center of one of the two rotating frames 109 without rotating. The three rotating rings 105 and nine hammers 104, which are rotatably connected to the hollow shaft 101, rotate with the treatment tank 108, which fully and evenly pound and impact the materials in the tank. During the rotation of the treatment tank 108, other required agents can be added into the tank at any time through the opening end of the hollow shaft 101 through multiple liquid outlet holes 106.
[0032] Secondly, the feed inlet 107 at the lower end of the processing tank 108 is opened, and the pre-treated material enters the drying mechanism 4 from the upper opening of the drying chamber. When the material enters the drying mechanism 4, the power shaft 405 is first driven to rotate by the shaking motor 410. Then, the power shaft 405 drives the inner support frame 401 and the conveyor belt 407 to start to rotate eccentrically through the eccentric disc 406. At this time, the material falling on the conveyor belt 407 will be moved and turned over by the conveyor belt 407, which ultimately avoids the accumulation of material and improves the drying and sterilization effect. Finally, it can be removed from the inside of the device through the discharge plate 411.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
