Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a multi-stage circulating hot air loading drying device. Background Art

[0002] Loading and drying equipment is a widely used device in numerous industries. It removes moisture from materials through heating and air circulation, thereby achieving drying. Loading and drying equipment plays a key role in modern industrial production and agricultural product processing. Its significant advantages can effectively extend the storage life of materials and reduce problems such as mold and rot caused by excessive moisture.

[0003] Existing loading and drying devices are usually composed of main mechanical structures such as a drying box, heating elements, fans, and material racks. During operation, the heating elements convert electrical energy or other energy sources into thermal energy, increasing the temperature of the air inside the box. The fans are responsible for circulating the hot air within the box, promoting full contact between the hot air and the material to achieve moisture evaporation. The material is placed on a fixed material rack and gradually loses moisture under the action of continuous hot air, completing the drying process. This traditional structure and workflow meet basic drying needs to a certain extent, and has been continuously improved and optimized in long-term practice. It is still widely used in the drying process of many common materials.

[0004] However, the existing loading and drying devices have certain shortcomings. Their internal drying effects are relatively simple and difficult to flexibly optimize according to the characteristics of the materials at different drying stages. Due to the inability to accurately control the drying conditions at different stages, relatively fixed parameters such as temperature and wind speed can often only be used during the entire drying process. This not only leads to low overall efficiency of the drying process and consumes a lot of energy and time, but also easily causes uneven heating of the materials during the drying process. Especially for some materials with more stringent requirements for drying conditions, the surface will be over-dried while the internal moisture will remain, which seriously affects the quality of the items and limits the application and development of loading and drying devices in fields with high drying quality requirements. Therefore, a multi-stage circulating hot air loading and drying device is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a multi-stage circulating hot air loading and drying device, which aims to improve the problem that the drying effect inside the equipment is relatively single and cannot be optimized according to the characteristics of the material in different drying stages, resulting in low overall efficiency of the drying process and even damage to the quality of the items.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 2-Figure 4 The utility model provides an embodiment: a multi-stage circulating hot air loading drying device, comprising a drying box 1, a plurality of fixed blocks 3 are fixedly connected to the inside of the drying box 1, each fixed block 3 is fixedly connected to a drying fan 4, and a drying component and a fixed component are provided inside the drying box 1;

[0033] The drying assembly includes multiple turntables 6, which are located on both sides of the interior of the drying box 1. Support frames 7 are fixedly connected to both sides of the inner wall of the drying box 1. The support frames 7 play a supporting role in stabilizing the turntable 6 and enabling it to rotate smoothly, ensuring that the turntable 6 does not deviate or shake during the rotation process. The support frame 7 on one side is rotatably connected to the outer wall of the turntable 6 on one side, and the top of the support frame 7 on the other side is fixedly connected to the outer wall of the turntable 6 on the other side. The inner wall of the drying box 1 is fixedly connected to a motor 5, and the output end of the motor 5 is fixedly connected to the outer wall of the turntable 6 on one side. The outer wall of the turntable 6 on one side is fixedly connected to multiple connecting strips 8, and one end of each connecting strip 8 is rotatably connected to a fixing frame 10. The fixing frame 10 is The bearing component for placing the material to be dried is connected to the connecting bar 8 through rotation. It can move in a specific trajectory under the drive of the turntable 6, so that the material can flow between different drying areas. The outer walls of the connecting bars 8 on the adjacent two sides are rotatably connected to the connecting plate 9. A plurality of slides 12 are provided inside the turntable 6 on the other side. A plurality of slides 11 are fixedly connected to one side of each fixed frame 10. The outer wall of the slide 11 is slidably connected to the inner wall of the slide 12. The slide 12 provides a sliding track for the slide 11 on one side of the fixed frame 10, which plays a guiding and limiting role, ensuring that the fixed frame 10 will not rotate during the revolution, so that the material can be cyclically dried according to the predetermined path and method;

[0034] Specifically, when the drying fans 4 are started, the heat and wind speed generated by the drying fans 4 show obvious differences due to their layout design at different heights. This difference naturally forms a plurality of different drying areas inside the drying box 1, each area having a unique thermal environment and wind field conditions. Then, the motor 15 is started. The motor 15 drives the turntable 16 connected to it to slide within the internal space defined by the support frame 7 by virtue of its stable power output characteristics. During the dynamic process of continuous rotation of the turntable 16, the connection constructed by the connecting strip 18 is used to connect the turntable 16 to the drying box 1. The connecting link acts as a link, driving the connecting plate 9 connected thereto to rotate and move synchronously, further prompting the fixed frame 10 to carry out an orbital motion with the position of the turntable 6 as the center of the circle. While the fixed frame 10 is rotating, its accompanying slide 11 will smoothly slide along the inner wall of the corresponding slide groove 12, effectively ensuring that the fixed frame 10 will not rotate during the orbital stroke, thereby maintaining the stability and accuracy of the movement. Through the orderly orbital motion of the fixed frame 10, the items placed on it can be accurately moved step by step to different drying areas. In this way, according to the different state characteristics of the items during the drying process, such as initial moisture content, material structural characteristics, and real-time drying degree, targeted drying processing operations can be carried out on them, thereby achieving the intended purpose of multi-stage cycle drying and improving the overall drying quality and processing effect of the equipment.

[0035] Reference Figure 1 、 Figure 3 and Figure 5 The fixing assembly includes a plurality of clamping plates 19, which are located inside the drying box 1. The main function of the clamping plates 19 is to firmly clamp the items to be dried placed on the fixing frame 10 to prevent the items from being displaced due to shaking, rolling, etc. during the drying process, thereby ensuring the smooth progress of the drying operation and the consistency and stability of the drying effect. Each fixing frame 10 is fixedly connected to a motor 2 13 at the bottom, and a door panel 2 is rotatably connected to one side of the drying box 1. The output end of each motor 2 13 is fixedly connected to a turntable 2 14, and both sides of each turntable 2 14 are fixedly connected to a connecting bar 2 15, and the outer wall of each connecting bar 2 15 is rotatably connected to Connecting plate 20, each connecting plate 20 is fixedly connected to a connecting strip 3 16 inside, each connecting strip 3 16 is rotatably connected to the inside of the splint 19, and the inner wall of each fixing frame 10 is fixedly connected to a plurality of limit strips 18, and the limit strips 18 play a precise guiding and limiting role on the movement of the splint 19, so that the splint 19 can only move along the direction specified by the limit strip 18 during the opening and closing process, avoiding the splint 19 from deflecting, shaking and other unstable conditions, thereby ensuring the accuracy and reliability of the clamping of the article, the limit strip 18 is slidably connected to the inside of the splint 19, and the inner wall of each fixing frame 10 is fixedly connected to a fixing frame 2 17;

[0036] Specifically, when securing the items to be dried, the items must first be placed steadily on top of the second fixing frame 17. Then, motor 13 is activated. Motor 13 acts as a power source, and its output end steadily transmits power to turntable 14, driving turntable 14 in rotation. During this rotation, turntable 14, through the linkage mechanism between connecting bar 15 and connecting plate 20, drives connecting plate 20 in rotation. Connecting bar 15 acts as a force transmission medium, effectively converting the rotational force of turntable 14 into linear movement force for connecting plate 20. As connecting plate 20 moves, it further drives the clamping plates 19 located on both sides via connecting bar 3 16. The splint 19 moves to the opposite side along the outer wall of the limit bar 18. The limit bar 18 accurately limits and guides the moving path of the splint 19, ensuring that the splint 19 can move stably in the predetermined direction until the splint 19 moves closely to the outer wall of the object, thereby successfully achieving a firm clamping and fixation of the dried object, enhancing the stability of the dried object during the drying process, and effectively avoiding problems such as poor drying effect caused by shaking or displacement of the object.

[0037] Working principle: In the process of fixing the items to be dried, the items are placed on the top of the fixing frame 2 17, and then the motor 2 13 is started. The output end of the motor 2 13 drives the turntable 2 14 to rotate, thereby driving the connecting plate 2 20 to rotate and move through the connecting bar 2 15, and then the clamping plates 19 on both sides are driven to move to the opposite side on the outer wall of the limit bar 18 through the connecting bar 3 16 until they move to the outer wall of the items, thereby clamping and fixing the items to be dried, and enhancing the stability of the items to be dried. Next, the drying fan 4 is started. The heat and wind speed of the drying fans 4 at different heights are different, so that different drying areas are formed inside the drying box 1. Then start the motor 5, and the output end of the motor 5 drives the turntable 6 on one side to slide inside the support frame 7. When the turntable 6 rotates, it drives the connecting plate 9 to rotate and move through the connecting bar 8, thereby driving the fixed frame 10 to revolve around the turntable 6 as the center of the circle. When the fixed frame 10 rotates, it drives the sliding bar 11 to slide on the inner wall of the sliding groove 12, so that the fixed frame 10 will not rotate during the revolution. The objects are moved to different drying areas through the revolution of the fixed frame 10, so that they can be dried in a targeted manner according to their different states, thereby achieving the purpose of multi-stage cycle drying and improving the drying quality of the equipment.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
