Description

Technical Field

[0001] This utility model relates to the field of tea drying technology, specifically to a circulating hot air energy-saving device for tea drying. Background Technology

[0002] The circulating hot air energy-saving device for tea drying is a piece of equipment specifically designed for tea drying. Its core principle is to achieve efficient heat utilization and energy saving through a hot air circulation system. Its main function is to transfer heat to the tea leaves, promoting moisture evaporation, while simultaneously recovering waste heat through a closed or semi-closed circulation system, reducing energy waste. Existing hot air circulating drying boxes, by adding a heat exchanger, utilize the high-temperature exhaust gas from the dryer to preheat the external cold air intake, reducing the energy burden of heating the cold air to the required drying temperature after it enters the dryer. In use, a tea tray containing tea leaves is placed on a support frame inside the drying box. The support frame is rotated by a motor, ensuring that the tea leaves on the tray are heated evenly.

[0003] The static placement of the tea tray on the support frame creates localized low-temperature zones between the tea leaves and the contact surface. The rate of moisture evaporation is much lower than that of the surface area, resulting in prolonged drying cycles and uneven product quality. Although some equipment incorporates dynamic rotation mechanisms to improve surface heating uniformity, the lack of design for dynamic disturbance within the tea layer makes it difficult to overcome the heat conduction barrier between the contact surface and the internal air. Therefore, a circulating hot air energy-saving device for tea drying is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving circulating hot air device for drying tea leaves, thereby solving the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is an energy-saving circulating hot air device for drying tea leaves, comprising:

[0006] A hot air circulating drying box and a support frame, wherein the support frame is rotatably connected inside the hot air circulating drying box;

[0007] The actuating assembly includes a rotating shaft, a support plate, a silicone toothed plate, a fixed frame, a connecting shaft, a torsion spring, and a baffle. The upper end of the rotating shaft is rotatably connected to the lower middle of the inclined tie rod in the middle of the support frame. The support plate is fixed to the lower end of the rotating shaft. The silicone toothed plate is fixed to the lower end of the support plate. The fixed frame is fixed inside one side of the hot air circulating drying box. The connecting shaft is fixed inside the fixed frame. One end of the baffle is sleeved on the middle of the connecting shaft. The torsion spring is sleeved on both ends of the connecting shaft, with one end fixed to the side of the baffle and the other end fixed to the side of the fixed frame.

[0008] Furthermore, one end of the support plate extends out of the support frame and is movably connected to the side of the baffle.

[0009] Furthermore, the support frame is evenly distributed with placement trays, and each placement tray corresponds to a diagonal tie rod.

[0010] Furthermore, the silicone toothed plate is located inside the placement tray and is movably connected to the placement tray.

[0011] Furthermore, the support plate is longer than the silicone toothed plate, and one end of the support plate and the silicone toothed plate are aligned, while the other end extends out of the placement tray.

[0012] Furthermore, it also includes a connecting component, which includes a connecting tube, an opening, and a telescopic locking block. The lower end of the connecting tube is fixed to the upper end of the support plate, and the upper end is sleeved on the outside of the rotating shaft. There are two openings, which are opened on the side of the connecting tube. One end of the telescopic locking block is connected to the rotating shaft by a spring, and the other end is inserted into the opening.

[0013] Furthermore, when the telescopic block is inserted into the opening at the lower end of the connecting pipe, the support plate and the silicone toothed plate are higher than the top of the placement plate.

[0014] This utility model has the following beneficial effects:

[0015] This invention, through a specially designed actuating component, allows the rotating shaft, support plate, and silicone toothed plate to rotate simultaneously when the motor drives the support frame to rotate. When the support plate rotates to the baffle, it is blocked by the baffle, causing the support frame to continue rotating while the support plate remains in its current position, allowing the rotating shaft to rotate around the support frame. When the vertical rod of the support frame rotates to the support plate, it increases the thrust on the support plate, causing the support plate to push the baffle, which in turn causes the baffle to rotate around the connecting shaft on the fixed frame. The baffle is gradually pushed away from the support plate. After the support plate moves past the baffle, the baffle returns to its original position under the action of a torsion spring. During this process, the silicone toothed plate at the lower end of the support plate rotates on the placement tray, affecting the placement tray. The tea leaves inside are stirred. After the support frame rotates once, the motor drives the support frame to rotate in the opposite direction, repeating the above steps. The silicone toothed plate rotates in the opposite direction on the placement tray, stirring the tea leaves again. This setting, through the dynamic stirring design of the stirring component, causes the silicone toothed plate to periodically stir the tea leaf layer inside the placement tray, breaking the static heat conduction barrier between the tea leaves and the contact surface, allowing the internal hot and humid air to be quickly replaced, effectively eliminating local low temperature zones and shortening the drying cycle. When the support frame rotates forward and backward, the silicone toothed plate simultaneously produces forward / reverse stirring action, forcing a turbulent effect to form within the tea leaf layer, accelerating the moisture evaporation rate, and avoiding the problem of dead corner residue caused by unidirectional stirring.

[0023] 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.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is an energy-saving circulating hot air device for drying tea leaves, comprising:

[0026] Hot air circulating drying box 10 and support frame 11, the support frame 11 is rotatably connected to the inside of hot air circulating drying box 10;

[0027] Placement trays 12 are evenly placed on the support frame 11, and each placement tray 12 corresponds to a diagonal tie rod;

[0028] The hot air circulating drying oven 10 uses a fan to circulate air, ensuring uniform air circulation. The air source is driven by a circulating fan motor with a contactless switch, which drives the impeller through the heater to deliver hot air. The hot air then travels through the air duct to the inner chamber of the oven. The used air is then drawn back into the air duct to become the air source for recirculation and heating, ensuring uniform indoor temperature. When the temperature fluctuates due to the opening and closing of the door, the air circulation system quickly returns to operation until the set temperature is reached. The support frame 11 provides support, and the upper and lower shafts of the support frame 11 are rotated by a motor. The placement tray 12 is used to place tea leaves.

[0029] The actuating assembly includes a rotating shaft 20, a support plate 21, a silicone toothed plate 22, a fixing frame 23, a connecting shaft 24, a torsion spring 25, and a baffle 26. The upper end of the rotating shaft 20 is rotatably connected to the middle of the lower end of the inclined tie rod in the middle of the support frame 11. The support plate 21 is fixed to the lower end of the rotating shaft 20. The silicone toothed plate 22 is fixed to the lower end of the support plate 21. The fixing frame 23 is fixed to one side inside the hot air circulating drying box 10. The connecting shaft 24 is fixed to the inner side of the fixing frame 23. One end of the baffle 26 is sleeved on the middle of the connecting shaft 24. The torsion spring 25 is sleeved on both ends of the connecting shaft 24, with one end fixed to the side of the baffle 26 and the other end fixed to the side of the fixing frame 23.

[0030] One end of the support plate 21 extends out of the support frame 11 and is movably connected to the side of the baffle 26;

[0031] The silicone toothed plate 22 is located inside the placement tray 12 and is movably connected to the placement tray 12;

[0032] The support plate 21 is longer than the silicone toothed plate 22, and one end of the support plate 21 and the silicone toothed plate 22 are aligned, while the other end extends out of the placement plate 12.

[0033] The rotating shaft 20 facilitates the rotation of the support plate 21, which serves as both support and connection. The silicone toothed plate 22 is used to stir the tea leaves. The fixing frame 23 provides support. The connecting shaft 24 facilitates the rotation of the baffle 26. The torsion spring 25 has a reset function. When the support plate 21 drives the silicone toothed plate 22 to rotate and stir the tea leaves, the resistance it experiences is less than the torque of the torsion spring 25. The baffle 26 serves as a limit.

[0034] Working principle:

[0035] When the motor drives the support frame 11 to rotate, the rotating shaft 20, support plate 21, and silicone toothed plate 22 rotate accordingly. When the support plate 21 rotates to the baffle 26, it is blocked by the baffle 26. While the support frame 11 continues to rotate, the support plate 21 remains at its current position, causing the rotating shaft 20 to rotate around the support frame 11. When the vertical rod of the support frame 11 rotates to the support plate 21, it increases the thrust on the support plate 21, causing the support plate 21 to push the baffle 26, which in turn drives the baffle 26 to rotate around the fixed frame 23. As the connecting shaft 24 rotates, the baffle 26 is gradually pushed away from the support plate 21. After the support plate 21 moves past the baffle 26, the baffle 26 returns to its original position under the action of the torsion spring 25. During this process, the silicone toothed plate 22 at the lower end of the support plate 21 rotates on the placement tray 12, stirring the tea leaves in the placement tray 12. After the support frame 11 rotates once, the motor drives the support frame 11 to rotate in the opposite direction. The above steps are repeated, and the silicone toothed plate 22 rotates in the opposite direction on the placement tray 12, stirring the tea leaves again.

[0036] In this step, through the dynamic tossing design of the tossing component, the silicone toothed plate 22 periodically stirs the tea layer inside the placement tray 12, breaking the static heat conduction barrier between the tea and the contact surface, allowing the internal hot and humid air to be quickly replaced, effectively eliminating local low temperature zones, shortening the drying cycle. When the support frame 11 rotates forward and backward, the silicone toothed plate 22 simultaneously generates forward / reverse tossing action, forcing a turbulent effect to form inside the tea layer, accelerating the moisture evaporation rate, while avoiding the problem of dead corner residue caused by unidirectional tossing.

[0037] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The connecting assembly includes a connecting pipe 30, an opening 31, and a telescopic locking block 32. The lower end of the connecting pipe 30 is fixed to the upper end of the support plate 21, and the upper end is sleeved on the outside of the rotating shaft 20. There are two openings 31, which are opened on the side of the connecting pipe 30. One end of the telescopic locking block 32 is connected to the rotating shaft 20 by a spring, and the other end is inserted into the opening 31.

[0039] When the telescopic block 32 is inserted into the opening 31 at the lower end of the connecting pipe 30, the support plate 21 and the silicone toothed plate 22 are higher than the uppermost end of the placement plate 12.

[0040] The connecting pipe 30 serves as a connection, the opening 31 and the telescopic block 32 serve as limiting devices, and a spring is installed inside the rotating shaft 20 to control the movement of the telescopic block 32.

[0041] Working principle:

[0042] Place the tea leaves on the placement tray 12. At this time, the opening 31 at the lower end of the connecting tube 30 is locked in the telescopic block 32. After placing the placement tray 12 on the support frame 11, press the telescopic block 32 and pull the connecting tube 30 down, which will cause the support plate 21 and the silicone toothed plate 22 to move down. The telescopic block 32 moves into the opening 31 at the upper end of the connecting tube 30.

[0043] This step facilitates the movement of the support plate 21 and the silicone toothed plate 22 without affecting the removal of the placement tray 12.
