DETAILED DESCRIPTION

[0029] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Example

[0031] The driving mechanism includes a rear small shaft 23 and a rear large shaft 24 which are rotatably connected to the side wall of the rear mounting sleeve 2. The rear large shaft 24 is fixed to the end of the screw rod 6. The side walls of the rear small shaft 23 and the rear large shaft 24 are respectively fixed with a rear small leaflet 25 and a rear large leaflet 26.

[0032] The side wall of the rear mounting sleeve 2 is rotatably connected with a connecting tube 14, and a rear middle tooth 28 is fixed to the end of the connecting tube 14. The side walls of the rear small shaft 23 and the rear large shaft 24 are respectively fixed with rear small teeth 27 and rear large teeth 29, and the rear middle teeth 28 are meshed with the rear small teeth 27 and the rear large teeth 29.

[0033] The dehumidification mechanism includes a front large shaft 15 rotatably connected to the inner wall of the front mounting sleeve 1, and a plurality of drying tubes 19 are fixed to the side wall of the front large shaft 15. Desiccant is placed inside the drying tube 19. The drying tube 19 is a mesh tube. After the drying tube 19 rotates, the desiccant inside the drying tube 19 will continue to shake, so that the desiccant can fully contact with the airflow during the continuous movement, while avoiding the adhesion of the desiccant, which is convenient for the subsequent treatment of the desiccant. A plurality of air inlet holes 20 are opened through the side wall of the front mounting sleeve 1, and the connecting tube 14 passes through the front mounting sleeve 1 and is connected thereto. A transfer hole 21 connected to the interior of the rear mounting sleeve 2 is opened on the side wall of the rear mounting sleeve 2, and an air outlet hole 22 is opened through the side wall of the rear mounting sleeve 2.

[0034] A front small shaft 12 is rotatably connected to the side wall of the front mounting sleeve 1. A front small shaft 16, a front middle tooth 17 and a front large tooth 18 are fixed to the side walls of the front small shaft 12, the connecting tube 14 and the front large shaft 15 respectively. The front middle tooth 17 is meshed with the front small tooth 16 and the front large tooth 18. The meshing of the gears is used to transmit motion, so that the kinetic energy of the airflow can be effectively utilized.

[0035] The side walls of the connecting pipe 14 and the rear main shaft 24 located in the inner section of the rear mounting sleeve 2 are respectively fixed with a front impact rod 30 and a rear impact rod 31. The inner wall of the rear mounting sleeve 2 is connected to the rear filter 32 and the front filter 33 through a shaking spring 37. The rotation of the connecting pipe 14 and the rear main shaft 24 will cause the front impact rod 30 and the rear impact rod 31 to collide with the front filter 33 and the rear filter 32, so that the filter will continuously shake and shake off the intercepted impurities. It only needs to clean the fallen impurities regularly, and the filter can be used for a long time.

[0036] A cooling box 34 is fixedly passed through the side wall of the rear installation sleeve 2, an air intake hopper 35 is inserted through the lower side wall of the cooling box 34, an ice bag is placed inside the cooling box 34, and an exhaust port 36 is passed through the upper side wall of the cooling box 34; the air intake hopper 35 is close to the rear shaft 24, the exhaust port 36 is close to the air outlet 22, the front filter 33 is located between the connecting pipe 14 and the rear shaft 24, and the rear filter 32 is located between the rear shaft 24 and the cooling box 34. The airflow transfer process can achieve multiple interception and cooling treatment, thereby ensuring that the airflow does not affect the workshop environment after being discharged;

[0037] In the present invention, in actual use, the front mounting sleeve 1 and the rear mounting sleeve 2 are stably placed in the drying room. During detection, the average speed hole 10 is used to test the average wind speed of the equipment, and the equal pressure hole 11 is used to test the average pressure of the equipment. The equipment is connected to the external program to calculate and display the results, and the average wind speed and wind pressure before and after the fan of the drying room are tested, and the actual wind resistance of the drying room is calculated. Combined with the required internal swirl wind speed of the drying room, the wind volume and wind pressure of the fan are calculated for selection;

[0038] During the airflow, the rear leaflet 25 and the rear leaflet 26 will be driven to rotate, thereby driving the rear large shaft 24 to rotate, and the rear large shaft 24 will drive the screw rod 6 to rotate, and the screw rod 6 will drive the connected mounting ring 5 to do reciprocating horizontal movement, so that the detection position is constantly changed, thereby improving the accuracy of the detection and reasonably utilizing the kinetic energy of the airflow;

[0039] The airflow will also enter the front installation sleeve 1 through the air inlet 20, and then pass through the drying tube 19. After being dried by the desiccant inside the drying tube 19, the airflow will be transferred to the rear installation sleeve 2 through the connecting tube 14, and finally discharged from the air outlet 22, thereby achieving dehumidification of the high-humidity airflow, thereby avoiding a greater impact on the environment.

[0040] The flow of airflow will also drive the front leaflet 13 to rotate, thereby causing the front small shaft 12 to rotate, and the front small shaft 12 will drive the front small tooth 16 to rotate, and finally drive the front large shaft 15 to rotate, and the front large shaft 15 will drive the drying tube 19 to rotate continuously, so that multiple drying tubes 19 can rotate and evenly contact the airflow, and at the same time, the desiccant will move inside the drying tube 19 due to inversion, thereby avoiding the adhesion of the desiccant, facilitating the cleaning of the desiccant in the later stage, and at the same time, the continuous movement of the desiccant can ensure full contact with the airflow, thereby improving the treatment effect;

[0041] After the airflow is dried, it will be transferred in the rear installation sleeve 2, first passing through the front filter 33, then passing through the rear filter 32, and then entering the cooling box 34 through the air inlet 35, leaving the cooling box 34 through the exhaust port 36, and finally discharged from the air outlet 22. In this process, the airflow is intercepted and filtered twice by the front filter 33 and the rear filter 32, so that the impurities and dust in the airflow are effectively cleaned, thereby ensuring the cleanliness of the interior of the drying room, and when the airflow passes through the cooling box 34, it will generate effective heat transfer with the internal ice bag, so that the temperature of the airflow is reduced after escaping, thereby avoiding the occurrence of high-heat airflow affecting the environment;

[0042] During the rotation of the connection pipe 14 and the rear main shaft 24, the front impact rod 30 and the rear impact rod 31 will be driven to rotate. The front impact rod 30 and the rear impact rod 31 will collide with the front filter 33 alternately during their rotation. At the same time, the rear impact rod 31 will also collide with the rear filter 32. Therefore, during the airflow transfer process, the rear filter 32 and the front filter 33 are constantly shaken with the cooperation of the shaking spring 37, thereby shaking off the dust and impurities intercepted on the surface, thereby maintaining effective filtering capacity, increasing the continuous use time of the equipment, and transforming the equipment from simple detection to continuous monitoring, thereby improving the use effect of the equipment.
