Description

Technical Field

[0001] This application relates to the field of hot air dryer technology, and in particular to a material handling device for a self-preheating hot air dryer. Background Technology

[0002] The hot air dryer first heats the air to a certain temperature through a heater to form hot air. The hot air is sent into the drying chamber through a specific air duct or pipe to exchange heat with the material to be dried. During the heat exchange process, the hot air will take away the moisture on the surface of the material, forming humid air. Finally, the humid air is discharged from the drying chamber through the exhaust port, and the dried material is collected.

[0003] Existing hot air dryers often suffer from uneven hot air distribution when processing materials, resulting in heat not being evenly transferred to every part of the material. This uneven heating method causes localized over-drying or over-wetting of the material during the drying process, thus affecting drying efficiency and product quality. To address this issue, we propose a self-preheating hot air dryer material handling device. Utility Model Content

[0004] The purpose of this application is to provide a self-preheating hot air dryer material processing device, which solves the problem of uneven hot air distribution in existing hot air dryers when processing materials. This results in heat not being evenly transferred to every part of the material. This uneven heating method causes local over-drying or over-wet phenomena in the material during the drying process, thereby affecting drying efficiency and product quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-preheating hot air dryer material handling device includes a drying chamber. A hot air blowing mechanism and a hot air recovery mechanism are provided on the top of the drying chamber. A set of equally spaced rotating rods are rotatably connected to the inner wall of the drying chamber. An air guide plate is fixedly connected to the outer surface of each rotating rod, and a push plate is fixedly connected to the outer surface of each rotating rod. A motor is installed on the inner wall of the drying chamber. A threaded rod is fixedly connected to the output end of the motor. A movable frame is threadedly connected to the outer surface of the threaded rod. Two sets of push frames disposed outside the push plates are fixedly connected to the bottom surface of the movable frame.

[0007] In a further embodiment, two support frames are fixedly connected to the inner wall of the drying chamber, and a carrier plate is provided inside the two support frames.

[0008] In a further embodiment, the inner wall of the drying chamber has two support grooves, and a set of support blocks are slidably connected to the inner wall of each support groove. The ends of the two sets of support blocks that are close to each other are respectively connected to the front and back of the moving frame.

[0009] In a further embodiment, two limiting rings are fixedly connected to the outer surface of the threaded rod, and the two limiting rings are respectively located on the left and right sides of the movable frame.

[0010] In a further embodiment, the inner wall of the drying chamber is fixedly connected with two sets of arc-shaped frames coaxial with the rotating rod. Each arc-shaped frame has a connecting column slidably connected to its inner wall. The ends of each set of connecting columns that are close to each other are respectively connected to the front and back of each air guide plate.

[0011] In a further embodiment, a sealed door is provided on the front of the drying chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This application utilizes a combination of a motor, threaded rod, moving frame, push frame, push plate, rotating rod, and air guide plate. By leveraging the reciprocating motion of the motor, the threaded rod rotates back and forth, the moving frame drives the push frame to push the push plate, and the air guide plate deflects left and right, hot air can be evenly directed to the surface of the material. This protects the drying effect on the material and further improves drying efficiency and product quality.

[0014] The combination of the support groove and the support block provides support for the moving frame, enabling it to move smoothly. The combination of the arc-shaped frame and the connecting column stabilizes the bottom of the air guide plate, ensuring its stability during air guidance. Attached Figure Description

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] 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.

[0021] Please see Figure 1-3 In this utility model, a self-preheating hot air dryer material processing device includes a drying chamber 1. A hot air blowing mechanism 2 and a hot air recovery mechanism 3 are provided on the top of the drying chamber 1. The hot air blowing mechanism 2 can blow hot air into the drying chamber 1 to achieve the drying effect. At the same time, the hot air recovery mechanism 3 can recover the hot air inside the drying chamber 1 and can recover the residual heat of the air inside the hot air blowing mechanism 2 to accelerate its heating speed.

[0022] Two support frames 9 are fixedly connected to the inner wall of the drying chamber 1. The two support frames 9 are equipped with a carrier plate 8 inside. The carrier plate 8 can support the material, and the staff can pull the carrier plate 8 smoothly on the support frame 9.

[0023] The front of the drying chamber 1 is equipped with a sealed door. The sealed door not only makes it convenient for staff to take out materials, but also prevents the leakage of hot air inside the drying chamber 1.

[0024] A set of rotating rods 7 arranged at equal intervals are rotatably connected to the inner wall of the drying chamber 1. Each rotating rod 7 has an air guide plate 10 fixedly connected to its outer surface and a push plate 17 fixedly connected to its outer surface. The push plate 17 is located above the rotating rod 7 and the air guide plate 10 is located below the rotating rod 7.

[0025] A motor 15 is installed on the inner wall of the drying chamber 1. A threaded rod 4 is fixedly connected to the output end of the motor 15. A movable frame 5 is threadedly connected to the outer surface of the threaded rod 4. Two sets of push frames 13 set outside the push plate 17 are fixedly connected to the bottom surface of the movable frame 5. When the motor 15 reciprocates, it drives the threaded rod 4 to reciprocate. When the threaded rod 4 rotates forward, the movable frame 5 drives the push frame 13 to move to the left. The push frame 13 then pushes the push plate 17, and the air guide plate 10 guides the air to the right. Conversely, the air guide plate 10 guides the air to the left. By reciprocating in this way, the air guide plate 10 can evenly guide the hot air to the surface of the material, which can ensure the comprehensive drying of the material, thereby improving the drying efficiency and product quality.

[0026] The inner wall of the drying chamber 1 has two support grooves 11. Each support groove 11 has a set of support blocks 6 slidably connected to its inner wall. The two sets of support blocks 6 are connected to the front and back of the moving frame 5 respectively at their close ends. By using the cooperation of the support grooves 11 and the support blocks 6, the moving frame 5 can be suspended and moved smoothly.

[0027] The inner wall of the drying chamber 1 is fixedly connected with two sets of arc-shaped frames 16 coaxial with the rotating rod 7. Each arc-shaped frame 16 has a connecting column 14 slidably connected to its inner wall. The ends of each set of connecting columns 14 that are close to each other are connected to the front and back of each air guide plate 10, respectively. By using the cooperation between the arc-shaped frame 16 and the connecting column 14, the bottom end of the air guide plate 10 can be stabilized, which can ensure its stability when deflecting and guiding air.

[0028] Two limiting rings 12 are fixedly connected to the outer surface of the threaded rod 4. The two limiting rings 12 are located on the left and right sides of the moving frame 5, respectively. The movement of the moving frame 5 can be restricted by the limiting rings 12, which can prevent the push frame 13 from separating from the push plate 17.

[0029] The working principle of this application is as follows: When in use, the material is placed on the carrier plate 8. When the hot air blowing mechanism 2 blows air into the drying chamber 1, the motor 15 is started to reciprocate. The motor 15 drives the threaded rod 4 to reciprocate. When the threaded rod 4 rotates forward, the moving frame 5 drives the push frame 13 to move to the left. The push frame 13 then pushes the push plate 17, and the air guide plate 10 guides the air to the right. Conversely, the air guide plate 10 guides the air to the left. This reciprocating operation ensures that the hot air is evenly directed to the surface of the material, thus guaranteeing the comprehensive drying of the material and improving drying efficiency and product quality.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
