[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Reference Figures 1 to 3A tunnel cooling unit is shown, which includes a tunnel body, a first cooling component and a second cooling component. The tunnel body includes a frame 11, a transmission steel belt 12 arranged on the frame 11, and a cover 13 covered on the top of the frame 11. The first cooling component is arranged in the tunnel body and close to the transmission steel belt 12. The first cooling component includes a water storage tank 21 and a plurality of spray heads 22 vertically upwardly arranged on the water storage tank 21. The plurality of spray heads 22 are connected to a water pump. The input end of the water pump is connected to the water storage tank 21. When the water pump is started, water in the water storage tank 21 is extracted and sprayed to the lower surface of the transmission steel belt 12 through the spray heads 22 to cool the lower surface of the transmission steel belt 12 and the material particles. For cooling, a second cooling component is arranged on the cover body 13, and the second cooling component includes a fan 31 arranged vertically downward at the upper end of the cover body 13 and a first cold air outlet 32 ​​arranged on the opposite sides of the cover body 13, the first cold air outlet 32 ​​is connected to an external cold air generating device, the first cold air outlet 32 ​​is aligned with the upper surface of the transmission steel belt 12, and the fan 31 also blows toward the upper surface of the transmission steel belt 12 / material particles when it is started, so as to increase the gas flow rate in the tunnel body and speed up the cooling of the material particles. The tunnel cooling unit of the utility model can make the upper and lower surfaces of the material particles cool more evenly and quickly, avoid the problem of material particles nodules and blocks, and improve the quality of the product.

[0018] In some possible embodiments, reference Figure 2 As shown, a scraper 23 is provided at the rear end of the water tank 21. The scraper 23 is tilted upward and abuts against the lower surface of the transmission steel belt 12. After the spray head 22 is aimed at the lower surface of the transmission steel belt 12 and sprays water mist to cool the transmission steel belt 12, the water mist is easily condensed into water droplets and adheres to the lower surface of the transmission steel belt 12. The scraper 23 is used to scrape off the condensed and adhered water droplets to prevent the water droplets from splashing out as the transmission steel belt 12 rotates to pollute the workshop environment.

[0019] In some possible embodiments, the spray head 22 and the first cold air outlet 32 ​​are staggered so that each position of the conveying steel belt 12 can be cooled to achieve a more uniform cooling effect.

[0020] In some possible embodiments, there are several fans 31 and they are arranged corresponding to the first cold air outlet 32. The fan 31 can blow the cold air blown out from the first cold air outlet toward the upper surface of the material particles / transmission steel belt 12, so that the cold air quickly contacts the surface of the material particles and takes away the heat of the material particles, thereby achieving a rapid cooling effect.

[0021] In some possible embodiments, two cold air delivery pipes 33 arranged up and down are provided on opposite sides of the cover body 13, a first cold air outlet 32 ​​is provided on the lower cold air delivery pipe 33, and a second cold air outlet 34 is provided on the upper cold air delivery pipe 33. In this embodiment, adding the second cold air outlet 34 can further enhance the cooling efficiency in the tunnel body; further, the first cold air outlet 32 ​​and the second cold air outlet 34 are staggered, and the first cold air outlet 32 ​​is aligned with the edge position of the transmission steel belt 12, and the second cold air outlet 34 is aligned with the center position of the transmission steel belt 12, so that the cold air can be blown more evenly to the upper surface of the transmission steel belt 12 / material particles.

[0022] In some possible embodiments, the cross-sectional opening size of the water tank 21 gradually increases from bottom to top, and the maximum opening size of the water tank 21 is larger than the width size of the transmission steel belt 12. The purpose is to ensure that water droplets attached to the lower surface of the transmission steel belt 12 can flow back into the water tank 21 to avoid polluting the workshop environment.

[0023] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
