This scheme sets a tin foil paper on the inner wall of the top of the machine shell. The tin foil paper has good heat absorption and heat retention functions. When the hot air converges at the top inside the machine shell, the tin foil paper absorbs the heat energy and, according to its own arc-shaped setting, radiates the heat to the center part, that is, the position where the wire cage is located, so as to bake the tea in the wire cage, improving the utilization rate of hot air and the efficiency of tea drying.

[0003] When drying tea in the prior art, the waste heat generated often directly discharges into the air, which means that the energy consumed in the drying process is not fully utilized, resulting in waste of energy. Since tea often needs to be preheated before drying, a tea rapid drying device that recovers waste heat and uses it to preheat tea is now proposed, aiming to save energy, reduce emissions and lower production costs. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tea rapid drying device.

[0005] The technical problem solved by the utility model is to recover waste heat and use it to preheat tea, thereby reducing energy waste and promoting energy conservation and emission reduction.

[0006] The utility model can be realized by the following technical solutions: including a conveyor belt installed at the bottom of the inner cavity of a drying box, dehumidifying boxes are fixedly installed on both sides of the drying box, an exhaust pipe is fixedly communicated between the front side of the drying box and the dehumidifying box, an air extraction pipe is fixedly communicated between the rear side of the drying box and the dehumidifying box, a plurality of first mesh plates are fixedly installed in the inner cavity of the dehumidifying box, a sliding rod is slidably installed through between the plurality of first mesh plates, second mesh plates are fixedly installed on one side of the outer peripheral wall of the sliding rod adjacent to the plurality of first mesh plates, and water-absorbing sponges are fixedly installed between a plurality of second mesh plates and the corresponding first mesh plates. A transmission component is installed on the dehumidifying box to intermittently urge the plurality of second mesh plates to simultaneously squeeze the plurality of water-absorbing sponges.

[0007] A further technical improvement of the present utility model lies in that: a rotating bracket is rotatably installed at a position between the front conveying area and the rear conveying area of the inner cavity of the drying box. The rotating bracket is driven by a belt pulley with the roller of the conveyor belt, and a plurality of evenly distributed tea stirring rods are rotatably installed on the rotating bracket.

[0008] Further, a plurality of springs abutting between the first mesh plate and the second mesh plate are embedded in each of the plurality of water-absorbing sponges.

[0009] Further, water leakage holes are formed at positions of the bottom plate of the dehumidifying box adjacent to the plurality of water-absorbing sponges. A waste water tank is fixedly communicated with the bottom of the dehumidifying box, and a drain pipe is fixedly communicated with the bottom of the waste water tank.

[0010] Further, the transmission assembly includes a rotating rod rotatably installed through a position of the waste heat recovery box adjacent to one of the second mesh plates, and a plurality of equidistantly distributed cams are fixedly installed on the outer peripheral wall of the rotating rod.

Specific embodiments

[0021] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific embodiments, structures, features and their effects of the present utility model as follows.

[0022] Please refer to Figures 1-4 As shown, this embodiment provides a tea rapid drying device, including a drying box 1. A conveyor belt 2 is arranged at the bottom of the inner cavity of the drying box 1. A rotating bracket 3 is rotatably installed above the conveyor belt 2 in the inner cavity of the drying box 1 adjacent to the conveyor belt 2. The rotating bracket 3 and the roller of the conveyor belt 2 are driven by pulleys (not shown in the figure). A plurality of evenly distributed tea stirring rods 4 are rotatably installed on the rotating bracket 3. The conveyor belt 2 is divided into a front conveying area and a rear conveying area from front to back with the rotating bracket 3 as the boundary. A feeding port 5 is installed at the position corresponding to the front conveying area of the conveyor belt 2 at the top of the drying box 1. A discharge port 6 is arranged at the position adjacent to the end of the conveyor belt 2 at the bottom of the drying box 1. Solenoid valves (not shown in the figure) are arranged on both the feeding port 5 and the discharge port 6. A hot air blower 7 is fixedly installed at the position corresponding to the rear conveying area of the conveyor belt 2 at the top of the inner cavity of the drying box 1;

[0023] Pour the tea to be dried into the front conveying area of the conveyor belt 2 in the drying box 1 through the feeding port 5. When the tea is conveyed from the front conveying area of the conveyor belt 2 to the rear conveying area by the conveyor belt 2, the rotating rotating bracket 3 will drive a plurality of tea stirring rods 4 to level the piled-up tea on the conveyor belt 2, and then blow hot air to the surface of the tea through the hot air blower 7 to dry the moisture in the tea;

[0024] On both sides of the drying oven 1, dehumidifying boxes 8 are fixedly installed. An exhaust pipe 9 is fixedly connected between the dehumidifying box 8 and the drying oven 1 at the position corresponding to the front conveying area of the conveyor belt 2. A suction pipe 10 is fixedly connected between the dehumidifying box 8 and the drying oven 1 at the position corresponding to the rear conveying area of the conveyor belt 2. An air extraction pump (not shown in the figure) for pumping the gas in the drying oven 1 into the dehumidifying box 8 is installed on the suction pipe 10. A plurality of first mesh plates 11 are fixedly installed in the inner cavity of the dehumidifying box 8. A sliding rod 12 is slidably installed through between the plurality of first mesh plates 11. On one side of the outer peripheral wall of the sliding rod 12 adjacent to the plurality of first mesh plates 11, a second mesh plate 13 is fixedly installed. A water-absorbing sponge 14 is fixedly installed between each of the several second mesh plates 13 and the corresponding first mesh plate 11.

[0025] After the tea leaves are dried, a large amount of hot gas containing moisture will be generated at the rear side of the inner cavity of the drying oven 1. The hot gas generated after drying the tea leaves is pumped into the dehumidifying box 8 through the suction pipe 10, so that the hot gas passes through the water-absorbing sponge 14 between the plurality of first mesh plates 11 and the second mesh plates 13. After being absorbed by the plurality of water-absorbing sponges 14, the water is discharged to the front conveying area of the conveyor belt 2 through the exhaust pipe 9, thereby preheating the tea leaves in the front conveying area of the conveyor belt 2.

[0026] A plurality of springs 15 abutting between the first mesh plates 11 and the second mesh plates 13 are embedded in each of the plurality of water-absorbing sponges 14. Leakage holes 16 are opened at the positions of the bottom plate of the dehumidifying box 8 adjacent to the plurality of water-absorbing sponges 14. A waste water tank 17 is fixedly connected to the bottom of the dehumidifying box 8. A drain pipe 18 is fixedly connected to the bottom of the waste water tank 17. A valve is installed on the drain pipe 18. A rotating rod 19 is rotatably installed through the dehumidifying box 8 adjacent to one of the second mesh plates 13. A plurality of cams 20 are fixedly installed on the outer peripheral wall of the rotating rod 19 at equal intervals.

[0027] When the rotating rod 19 rotates, it will drive the cam 20 to intermittently press the adjacent second mesh plate 13. When the cam 20 presses the second mesh plate 13, the second mesh plate 13 will drive other second mesh plates 13 to press the spring 15 and the water-absorbing sponge 14 in the direction of the corresponding first mesh plate 11 through the sliding rod 12, so that the spring 15 is in a stressed state, and the water in the water-absorbing sponge 14 is squeezed out. The squeezed water flows from the mesh holes of the first mesh plate 11 and the second mesh plate 13 to the leakage holes 16, and flows into the waste water tank 17 through the leakage holes 16, and finally is discharged to the outside of the waste water tank 17 through the drain pipe 18. When the cam 20 disengages from pressing the second mesh plate 13, the stressed spring 15 will rebound to its natural state, thereby driving the second mesh plate 13 to move back, so that the second mesh plate 13 drives the water-absorbing sponge 14 to return to its natural state.

[0028] When the utility model is in use, the tea leaves to be dried are poured onto the front conveying area of the conveyor belt 2 through the feeding port 5, and then the tea leaves are conveyed by the conveyor belt 2, so that the tea leaves are flattened on the conveyor belt 2 by several tea stirring rods 4 on the rotating support 3 after passing through the rotating support 3, and are conveyed to the rear conveying area of the conveyor belt 2. Then, the tea leaves in the rear conveying area of the conveyor belt 2 are dried by the hot air blower 7, and then the conveyor belt 2 conveys the dried tea leaves to the discharge port 6, and the dried tea leaves are discharged from the discharge port 6 to a designated position outside the drying box 1. The hot air generated during the tea drying process is drawn into the waste gas treatment box through the air extraction pipe 10, and then discharged to the front conveying area of the conveyor belt 2 through the exhaust pipe 9. During this process, the moisture in the hot air is absorbed by a plurality of water-absorbing sponges 14, so that the hot air discharged to the front side of the inner cavity of the drying box 1 is dry hot air. The continuously rotating rotating rod 19 drives several cams 20 to intermittently squeeze a plurality of second net plates 13 fixedly connected together by sliding rods 12, so that the plurality of second net plates 13 intermittently squeeze the springs 15 and the water-absorbing sponges 14 in the direction of the corresponding first net plate 11, thereby squeezing out the moisture absorbed by the water-absorbing sponges 14, and enabling the squeezed water to flow into the waste water tank 17 through the water leakage holes 16, and then discharged through the drain.

[0029] The above is only the preferred embodiment of the utility model, and does not impose any form of limitation on the utility model. Although the utility model has been disclosed above with the preferred embodiment, it is not intended to limit the utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to obtain an equivalent embodiment with equivalent changes within the scope of the technical solution of the utility model. However, as long as it does not depart from the content of the technical solution of the utility model, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model still fall within the scope of the technical solution of the utility model.
