[0033] By setting a fixing assembly and utilizing the rotation of the bidirectional screw rod 8 to make the fixing plate 4 move relatively, the device is fixed to the outer wall of the blast rod drying box, which facilitates the installation of the device.

[0034] Example 2

[0035] A drying exhaust device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 4As shown, the activated carbon plate 25 is connected to the filter chamber 24 via a limiting assembly, and the limiting assembly includes a slot 26, and the slot 26 is relatively opened on the inner walls on both sides of the filter chamber 24, and the inner wall on one side of the slot 26 is connected to the limiting plate 28 through a fixing spring 29, and a sealing gasket 27 is fixed to the inner wall on the opposite side of the slot 26 and the limiting plate 28, and the limiting plate 28 is slidably matched with the activated carbon plate 25.

[0036] When installing the activated carbon plate 25, the activated carbon plate 25 is inserted into the slot 26. The pressure of the activated carbon plate 25 on the limit plate 28 compresses the fixing spring 29. The elasticity of the fixing spring 29 is used to press the activated carbon plate 25 tightly against the surface of the sealing gasket 27, thereby fixing the activated carbon plate 25.

[0037] By providing a limit assembly and utilizing the elasticity of the fixing spring 29 to press the activated carbon plate 25 tightly against the surface of the sealing gasket 27 , the activated carbon plate 25 is fixed, making it easier to replace and clean the activated carbon plate 25 .

[0038] Working principle: When in use, start the motor 12 to drive the bidirectional screw 8 to rotate, so that the moving block 9 moves relatively along the bidirectional screw 8, and the telescopic rod 3 is driven to slide inside the mounting frame 2 through the connecting rod 10, and the fixing plate 4 moves accordingly. The device is fixed to the outer wall of the blast drying box through the fixing plate 4, and then the air inlet pipe 5 is connected to the exhaust pipe of the blast drying box. The high-temperature gas generated by the blast drying box when working enters the condensation chamber 14 along the air inlet pipe 5, and the water filter plate 15 in the condensation chamber 14 collects the water vapor mixed in the gas and condenses it into water droplets. The water droplets fall along the water filter plate 15 to the bottom of the condensation chamber 14 and fall into the water storage chamber 17 through the water collecting pipe 16. The gas after dehydration enters the cooling chamber 30, and the circulating pump 22 is started at the same time to cool the condensation chamber 14. The coolant in the cooling tank 21 circulates along the spiral cooling pipe 23 to cool the gas. The cooled gas enters the filter chamber 24 through the connecting pipe 20. The activated carbon plate 25 filters the gas to remove impurities mixed in the gas. At the same time, the exhaust fan 7 is started to extract the air in the filter chamber 24 to form a negative pressure to accelerate the flow of gas. When a certain amount of water is stored in the water storage chamber 17, the sealing plug 19 is pulled out to drain the water. When installing the activated carbon plate 25, the activated carbon plate 25 is inserted into the slot 26. The pressure of the activated carbon plate 25 on the limit plate 28 compresses the fixed spring 29. The elasticity of the fixed spring 29 is used to press the activated carbon plate 25 against the surface of the sealing pad 27 to fix the activated carbon plate 25.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
