[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

When in use, the humidifying mechanism 3 can be used to humidify the crushed coking coal, and then the crushed coking coal can be humidified, and the humidified coking coal can be quickly air-dried by flowing air, thereby preparing for the subsequent drying of the coking coal. The coking coal is collected and used; by providing an exhaust mechanism 5, the smoke generated by the coking coal after humidity adjustment can be extracted, and by quickly extracting the air, the air can flow quickly, thereby ensuring the rapid drying of the coking coal; by providing a screening mechanism 4, the screening work can be completed after the crushed coking coal is crushed, and the dredging work can be carried out at the same time as the screening work to prevent the crushed coking coal from being blocked, thereby ensuring the continuous progress of the crushing work, and the screening of the coking coal provides convenience for the screening and collection of the staff, thereby greatly reducing the working time.

[0024] The humidity control mechanism 3 includes a first fixed platform 31 fixedly connected to one side of the screening and humidity control box 1, a water pump 32 fixedly connected to the top of the first fixed platform 31, the input end of the water pump 32 is connected to the water tank 33 through a water inlet pipe, the water tank 33 is fixedly connected to the first fixed platform 31, and the output end of the water pump 32 is fixedly connected to a double-headed pipe 34, one side of the double-headed pipe 34 and located in the screening and humidity control box 1 is fixedly connected to a horizontal pipe 35, and one side of the horizontal pipe 35 is equidistantly fixedly connected to a plurality of nozzles 36. When in use, the water pump 32 is controlled to operate to extract water from the water tank 33, and then transported into the double-headed pipe 34 through the output end, and then transported into the horizontal pipe 35 through the double-headed pipe 34, and finally discharged through the multiple nozzles 36 on one side of the horizontal pipe 35, thereby performing humidity control on the crushed coking coal.

[0025] The exhaust mechanism 5 includes a suction fan 51 fixedly connected to both sides of the screening and humidity control box 1, and an air collecting hood 52 is fixedly connected to one side of the two suction fans 51 and located in the screening and humidity control box 1. A filter screen 53 is fixedly connected to the inner side of the air collecting hood 52. When in use, the suction fan 51 is controlled to run through the air collecting hood 52 to absorb flue gas and air, and the flue gas entering the air collecting hood 52 can be filtered through the filter screen 53 to filter smoke dust, so that the flowing air can dry the humidified coking coal.

[0026] The screening mechanism 4 includes a second motor 41 fixedly connected to one side of the screening and humidity control box 1, and the output end of the second motor 41 is fixedly connected to a rotating rod 42. One end of the rotating rod 42 is fixedly connected to a rotating disk 43 located in the screening and humidity control box 1, and four connecting rods 48 are fixedly connected to the outside of the rotating disk 43. Limited slots 44 are provided on both sides of the screening and humidity control box 1. Screening mesh plates 46 are slidably connected to the inner sides of the two limited slots 44. Four springs 45 are fixedly connected to the bottom of the four springs 45. The bottoms of the four springs 45 are fixedly connected to the bottom of the inner side of the limited slots 44. Guide plates 47 are fixedly connected to both sides of the screening mesh plates 46. When in use, the second motor 41 is controlled to move The rotating rod 42 is rotated so that the rotating rod 42 drives the rotating disk 43 to rotate. When the connecting rod 48 on the outside of the rotating disk 43 contacts the screening mesh plate 46, it will be pushed downward in the limiting slot 44, thereby causing the screening mesh plate 46 to compress the spring 45. When the rotating disk 43 no longer applies force to the screening mesh plate 46, the compressed spring 45 resets the screening mesh plate 46. This reciprocating process causes the screening mesh plate 46 to vibrate up and down, thereby screening the coking coal. After that, the screened coking coal can be collected on both sides and the bottom of the screening and humidity control box 1. When the rotating disk 43 rotates, the crushed coking coal can be dredged to prevent blockage. Example 2

A control panel 6 is fixedly connected to one side of the screening and humidity control box 1. The control panel 6 is electrically connected to the first motor 21, the water pump 32, the second motor 41 and the suction fan 51. The operation and use of the electrical appliances inside the device can be controlled through the control panel 6, thereby providing convenience for the staff.
