Description

Technical Field

[0001] This utility model relates to the field of drying equipment, specifically a hot air circulating drying equipment. Background Technology

[0002] Hot air circulation drying equipment is a device that uses the principle of hot air circulation to dry materials. It is widely used in food, medicine, chemical, agricultural products and other fields. Its main function is to distribute hot air evenly to the surface of materials through the hot air circulation system, accelerate the evaporation of moisture, and thus achieve the drying of materials.

[0003] However, current hot air circulating drying equipment still has some shortcomings. For example, the hot air in existing hot air circulating drying equipment is mostly unidirectional, which requires the staff to turn the materials over regularly during the drying process. This increases the workload of the staff and reduces the drying efficiency of the equipment, thus resulting in certain defects in use.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structure to provide a hot air circulation drying device. Utility Model Content

[0005] The purpose of this invention is to provide a hot air circulating drying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot air circulating drying device, comprising a drying chamber and an auxiliary drying mechanism. A sealing door is rotatably connected to the outside of the drying chamber via a hinge. A heater is installed on the inner surface of the bottom of the drying chamber. A bearing assembly is movably connected to the inner surface of the drying chamber, and a limiting net is movably connected to the inner surface of the bearing assembly. T-shaped sliders are symmetrically installed on the front and rear sides of the limiting net, and locking components are symmetrically installed on the top of the limiting net. The auxiliary drying mechanism is fixedly installed on the inner surface of the drying chamber. A dehumidification chamber is fixedly installed on the right side of the drying chamber, and an air supply mechanism is installed on the back of the dehumidification chamber. An exhaust pipe is fixedly connected to the top of the dehumidification chamber.

[0007] Furthermore, the supporting component includes a material carrying box, a breathable mesh, a T-shaped slide bar, a handle, and a limiting groove. The bottom of the material carrying box is embedded with a breathable mesh, and T-shaped slide bars are symmetrically installed on both sides of the material carrying box. A handle is embedded on the outer side of the material carrying box, and a limiting groove is formed on the inner surface of the material carrying box.

[0008] Furthermore, the side of the material carrier box is fixedly connected to the inner side of the T-shaped slide bar, and the material carrier box forms a sliding structure with the drying box through the T-shaped slide bar.

[0009] Furthermore, the outer side of the limiting net is fixedly connected to the inner side of the T-shaped slider, and the limiting net forms a sliding structure with the material carrier box through the T-shaped slider.

[0010] Furthermore, the locking assembly includes a fixed plate, a locking rod, a connecting plate, a pull ring, and a return spring. The locking rod is movably connected inside the fixed plate, and the end of the locking rod is fixedly connected to the connecting plate. The other end of the connecting plate is fixedly installed with a pull ring, and the inner side of the connecting plate is fixedly connected with a return spring.

[0011] Furthermore, the external dimensions of the locking rod end are perfectly matched with the internal dimensions of the limiting groove, and the locking rod forms a locking structure with the material carrier box through the limiting groove.

[0012] Furthermore, the end of the reset spring is fixedly connected to the side of the fixed plate, and the other end of the reset spring is fixedly connected to the end of the connecting plate, and the connecting plate and the fixed plate form an elastic structure through the reset spring.

[0013] Furthermore, the auxiliary drying mechanism includes a hollow support plate, a diversion air pipe and an air supply pipe. The diversion air pipe is fixedly installed at equal intervals on the inner surface of the hollow support plate, and the air supply pipe is fixedly connected to the outer side of the hollow support plate. The other end of the air supply pipe is fixedly connected to the bottom of the dehumidification box.

[0014] This utility model provides a hot air circulating drying device, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of the air supply pipe, allows the dehumidified hot air to be automatically transported into the interior of the hollow support plate. Then, through the connection of the hollow support plate, it is transported at equal distances into the interior of the diversion air guide pipe and blown evenly onto the upper surface of the support component through the air outlet at the bottom of the diversion air guide pipe. At the same time, through another air supply pipe at the bottom of the dehumidification box, the dehumidified hot air can also be transported into the lower end of the drying box. This achieves multi-faceted drying of the material carried in the support component, thereby avoiding the need for operators to turn the material over regularly during the drying process, which would interfere with the drying efficiency of the drying equipment.

[0016] 2. This utility model, through the design of a T-shaped slider, allows the limiting net to be quickly installed and removed by workers along the inner surface of the material carrier box. Then, with the cooperation of the locking component, the limiting net can be quickly locked when installed inside the material carrier box. Thus, the carrier component and the limiting net work together to firmly restrict the material to be dried inside the carrier component, thereby preventing the material from flying out of the carrier component when the circulating hot air blows and dries the material. Furthermore, because the locking component is elastically designed, it makes it more convenient for workers to install and remove the limiting net. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figure 1 and Figure 2 As shown, a hot air circulating drying device includes a drying chamber 1 and an auxiliary drying mechanism 8. A sealing door 2 is rotatably connected to the outside of the drying chamber 1 via a hinge. A heater 3 is installed on the inner surface of the bottom of the drying chamber 1, and a support assembly 4 is movably connected to the inner surface of the drying chamber 1. The auxiliary drying mechanism 8 is fixedly installed on the inner surface of the drying chamber 1. The auxiliary drying mechanism 8 includes a hollow support plate 81, a diversion air guide pipe 82, and an air supply pipe 83. The diversion air guide pipe 82 is fixedly installed at equal intervals on the inner surface of the hollow support plate 81, and the air supply pipe 83 is fixedly connected to the outside of the hollow support plate 81. The other end of the air supply pipe 83 is fixedly connected to the bottom of a dehumidification chamber 9. The dehumidification chamber 9 is fixedly installed on the right side of the drying chamber 1, and an air supply mechanism 10 is installed on the back of the dehumidification chamber 9. An exhaust pipe 11 is fixedly connected to the top of the dehumidification chamber 9.

[0024] like Figures 2-4As shown, a sealing door 2 is rotatably connected to the outside of the drying oven 1 via a hinge, and a heater 3 is installed on the inner surface of the bottom of the drying oven 1. A support assembly 4 is movably connected to the inner surface of the drying oven 1. The support assembly 4 includes a material support box 41, a breathable mesh 42, T-shaped slide bars 43, a handle 44, and a limiting groove 45. A breathable mesh 42 is embedded in the bottom of the material support box 41, and T-shaped slide bars 43 are symmetrically installed on both sides of the material support box 41. The sides of the material support box 41 are fixedly connected to the inner sides of the T-shaped slide bars 43, and the material support box 41 forms a sliding structure with the drying oven 1 through the T-shaped slide bars 43. The material carrier box 41 and the drying chamber 1 allow the material carrier box 41 to move back and forth more smoothly and stably along the inner surface of the drying chamber 1. A handle 44 is embedded on the outer side of the material carrier box 41, and a limiting groove 45 is formed on the inner surface of the material carrier box 41. A limiting mesh 5 is movably connected to the inner surface of the bearing assembly 4, and T-shaped sliders 6 are symmetrically installed on the front and rear sides of the limiting mesh 5. The outer side of the limiting mesh 5 is fixedly connected to the inner side of the T-shaped sliders 6, and the limiting mesh 5 forms a sliding structure with the material carrier box 41 through the T-shaped sliders 6. Through the sliding structure of the limiting mesh 5 and the material carrier box 41, the limiting mesh 5 moves smoothly and stably along the inner surface of the material carrier box 41. The inner surface of 41 moves more smoothly and stably during lifting and lowering. A locking assembly 7 is symmetrically installed on the top of the limiting mesh 5. The locking assembly 7 includes a fixing plate 71, a locking rod 72, a connecting plate 73, a pull ring 74, and a return spring 75. The fixing plate 71 is internally connected to the locking rod 72. The external dimensions of the end of the locking rod 72 perfectly match the internal dimensions of the limiting groove 45. The locking rod 72 forms a locking structure with the material carrier box 41 through the limiting groove 45. This locking structure between the locking rod 72 and the material carrier box 41 allows the locking rod 72 to be easily inserted into the material carrier box 41 to achieve automatic locking. A connecting plate 73 is fixedly connected to one end of the 2, and a pull ring 74 is fixedly installed on the other end of the connecting plate 73. A return spring 75 is fixedly connected to the inner side of the connecting plate 73. The end of the return spring 75 is fixedly connected to the side of the fixed plate 71, and the other end of the return spring 75 is fixedly connected to the end of the connecting plate 73. The connecting plate 73 and the fixed plate 71 form an elastic structure through the return spring 75. By setting the connecting plate 73 and the fixed plate 71 into an elastic structure, when the operator releases the pull ring 74, the connecting plate 73 can drive the locking rod 72 through the rebound force to pass through the fixed plate 71 and insert into the interior of the material carrier box 41 to complete the locking work.

[0025] In summary, this hot air circulating drying equipment is first based on Figures 1 to 4As shown in the diagram, the operator evenly spreads the material to be dried inside the material carrier box 41, then grasps the pull rings 74 on both sides and pulls them inward. Next, the limiting net 5 is installed into the material carrier box 41 by sliding the T-shaped slider 6. After the limiting net 5 is in place, the pull rings 74 are released, allowing the connecting plate 73 to be pushed by the return spring 75 to drive the locking rod 72 through the fixing plate 71 and into the limiting groove 45, thus locking the locking rod 72. The operator then grasps the lever 44 and slides the connecting plate 73 to install the material carrier box 41 into the drying chamber 1. After all the carrier components 4 are installed, the sealing door 2 is closed, and the heater 3 and air supply mechanism 10 are turned on by the controller. When the heater 3 starts running, it automatically raises the temperature inside the drying chamber 1. When the air supply mechanism 10 starts running, it draws air from the outside... Air is drawn into the dehumidification chamber 9 and dehumidified by the dehumidification mechanism inside. The dehumidified air is then transported through the air supply pipe 83 and the air delivery pipe into the hollow support plate 81 and the drying chamber 1, respectively. The hollow support plate 81 ensures that the air injected into it is evenly distributed into the diversion air guide pipe 82. The hot air is then evenly blown out through the air outlet at the bottom of the diversion air guide pipe 82, allowing the hot air to be more comprehensively blown to the support component 4 for thorough and uniform drying, thereby increasing the drying speed of the material in the support component 4. The hot air, carrying moisture, is then re-entered into the dehumidification chamber 9 for dehumidification through the exhaust pipe 11. The dehumidified hot air is then recirculated back into the diversion air guide pipe 82 and the drying chamber 1 for further drying.
