[0010] Advantageous Effects

[0011] Compared with the prior art, the advantages of the multi-layer big honey pill cooler conveyor of the present utility model are as follows:

[0012] 1. When cooling the big honey pills, the big honey pills with higher temperature move along the conveyor belt and fall from the throwing end of the upper conveyor belt to the lower conveyor belt to continue to move horizontally. During this process, the cold air of the central air conditioner enters the second cavity from the cold air inlet pipe, is further cooled by the condenser, and is blown into the first cavity by the cooling fan to contact the big honey pills to cool them. Since the cold air is used to cool the big honey pills and the cold air is cooled twice, not only the air supply temperature is stable, but also the cooling efficiency of the big honey pills is high.

[0013] 2. The condenser adopts a bent pipe with multiple bends, and the bent pipe is located in front of the air inlet of the cooling fan to ensure that the cold air blown out from the cooling fan is further cooled by the bent pipe of the condenser.

[0014] 3. Both the condenser and the cooling fan are at least two groups, and each cooling fan is arranged in sequence along the length direction of the conveyor belt to ensure the uniformity of the cold air distribution.

[0015] 4. The cold air blown into the first inner cavity can be discharged from the air dispersion holes, the inlet and the outlet of the box body, and the heat is dissipated from multiple directions to realize the rapid cooling of the big honey pills.

[0022] Embodiment

[0023] The specific implementation manner of the present utility model is as follows Figures 1 to 3 As shown, a multi-layer cooling pill conveyor includes a box body 1 and a plurality of conveyor belts 2. A first inner cavity 11 and a second inner cavity 12 which are separated from each other are arranged in the box body 1. Each conveyor belt 2 is arranged in sequence from top to bottom. The input end of the lower conveyor belt 2 is directly below the throwing end of the upper conveyor belt 2. At least the middle sections of each conveyor belt 2 are located in the first inner cavity 11. A cold air inlet pipe 4 is connected to the second inner cavity 12. A condenser 6 is arranged in the second inner cavity 12. The first inner cavity 11 and the second inner cavity 12 are communicated through a cooling fan 5. In this embodiment, there are five conveyor belts 2. The conveyor belts adopt a driving mode of a pulley driving a belt. The pulley is rotatably connected to a bracket (not shown in the figure) fixed inside or outside the box body 1. The pulley is also linked with a driving motor.

[0024] An inlet 15 and an outlet 16 are arranged on the side wall of the box body 1. The input end of the conveyor belt 2 at the topmost layer passes through the inlet 15 and extends out of the box body 1. An incoming pill guiding groove 3 is arranged above the input end of this conveyor belt 2. The output end of the conveyor belt 2 at the bottommost layer passes through the outlet 16 and extends out of the box body 1.

[0025] The condenser 6 includes a bent pipe 63 with a plurality of bending parts. The bent pipe 63 is located in front of the air inlet of the cooling fan 5. A cold water input end 61 and a cold water output end 62 are respectively arranged at both ends of the bent pipe 63. For the bent pipe 63 of each condenser 6, the overall width and height thereof are both adapted to the effective ventilation cross-section size of the cooling fan 5 to ensure that the cold air passing through the cooling fan 5 is cooled by passing through the bent pipe 63.

[0026] Both the condenser 6 and the cooling fan 5 are at least two groups. Each cooling fan 5 is arranged in sequence along the length direction of the conveyor belt 2. The number of groups of the condenser 6 and the cooling fan 5 is selected according to the length of the box body 1 to ensure that the big honey pills in the box body 1 can be blown by cold air for a long time. In addition, the number of cold air inlet pipes 4 is also at least two, and their arrangement direction is parallel to the length direction of the conveyor belt 2. The input end of the cold air inlet pipe 4 is communicated with the air outlet of the central air conditioner. The lower end of the cold air inlet pipe 4 is communicated with the top of the second inner cavity 12.

[0027] The first inner cavity 11 and the second inner cavity 12 are arranged horizontally, and are separated by a partition plate 14. The cooling fan 5 is installed on the partition plate 14. The side wall of the first inner cavity 11 is provided with air dispersion holes 13 for communicating it with the outside. The air dispersion holes 13 and the second inner cavity 12 are respectively located on both sides of the first inner cavity 11. In this embodiment, the air dispersion holes 13 are distributed on one side of each conveyor belt 2, which is beneficial to accelerating the discharge of heat.

[0028] In use, the big honeyed pills with a relatively high temperature after pill making roll along the pill inlet guiding groove 3 and fall on the topmost conveyor belt 2, and enter the box body 1 through the inlet 15 along the topmost conveyor belt 2. The big honeyed pills fall from the throwing end of the upper conveyor belt to the lower conveyor belt and continue to move horizontally. During this process, the cold air of the central air conditioner enters the second cavity 12 through the cold air inlet duct 4, is further cooled by the condenser 6, and is blown into the first cavity 11 by the cooling fan 5 to contact the big honeyed pills and cool them down. The big honeyed pills on the bottommost conveyor belt 2 are removed from the box body 1 through the outlet 16 of the box body 1.
