[0020] A method for using a cyanate prepolymer product drying device comprises the following steps:

[0021] S1: First, the flip cover is opened to add the cyanate prepolymer product into the drying barrel, and then the flip cover is closed and locked, and then the heating rod and the driving motor are started. The driving motor drives the heating rod to rotate, so as to achieve stirring while heating the cyanate prepolymer product, thereby ensuring the drying effect of the cyanate prepolymer product;

[0022] S2: With the progress of the cyanate prepolymer product, the solvent and water attached to the cyanate prepolymer product will evaporate into gas, so that high pressure is formed inside the drying barrel, and the high-pressure steam inside the drying barrel will enter the rectangular groove in the second groove block through the U-shaped tube, and the steam inside the rectangular groove will enter the left side of the cylindrical groove through the connecting tube connected thereto, which will further form high pressure inside the cylindrical groove to push the piston plate to move, and at the same time, the gas on the other side of the cylindrical groove will be discharged to the inside of the L-shaped tube through the connecting tube connected to the air outlet. The movement of the piston plate drives the movement of the first connecting rod, and the movement of the first connecting rod drives the movement of the lever and the movable rod, and the movement of the movable rod drives the flywheel to rotate. When the lever moves to contact the right lever plate, The paddle plate is rotated by the shaft rod, and the rotation of the paddle plate will drive the sliding column to move left, and the sliding column moves left to drive the second connecting rod to move left, and the movement of the second connecting rod drives the reversing valve to move left, so as to change the direction of the steam in the rectangular groove to enter the cylindrical groove from the right. At this time, the connecting pipe on the left side of the cylindrical groove is connected with the air outlet, and the steam will enter the right side of the cylindrical groove through the rectangular groove, so that the piston plate moves left and discharges the steam on the left side to the inside of the L-shaped tube through the air outlet. In addition, according to the inertia of the flywheel, the flywheel will rotate counterclockwise when the second connecting rod moves left. When the paddle rod moves left to contact with the paddle plate on the left, the paddle plate on the left will rotate. In summary, the reversing valve can be moved to the right by the same reasoning.

[0023] S3: The flywheel can be rotated by reciprocating in sequence, and the rotation of the flywheel drives the rotation of the rotating shaft, the rotation of the rotating shaft drives the rotation of the small pulley, the rotation of the small pulley drives the belt, the rotation of the belt drives the large pulley to rotate slowly, the slow rotation of the large pulley drives the turntable to rotate slowly, the rotation of the turntable drives the hinged rod to move, the movement of the hinged rod drives the vertical plate to move, the movement of the vertical plate drives the sliding plate to move up and down, the up and down movement of the sliding plate can make the coolant inside the cooling cylinder circulate from the cooling jacket through the two pipe bodies, and the coolant before and after use is separated by the sliding plate, which ensures the condensation effect of the coolant on the steam, and finally the condensed steam will be converted into liquid and enter the collection barrel to be collected. In summary, the steam of the dry cyanate prepolymer product can be collected by reciprocating in sequence.

[0024] The beneficial effects of the present invention are:

[0025] The present invention, through the arrangement of a steam utilization component, a collection component and a cooling component, can utilize the generated steam when the cyanate prepolymer product is dried to eliminate the solvent and moisture, automatically drive the coolant circulation to condense the steam, avoid directly discharging the steam to the outside, resulting in the waste of steam, solvent and moisture, so as to improve the utilization rate of resources, and can also monitor the drying process of the cyanate prepolymer product. When the flywheel stops rotating, it indicates that the drying of the cyanate prepolymer product is completed, thereby improving the use effect of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The driving motor (19) drives the heating rod (18) to rotate, so as to achieve stirring while heating the cyanate prepolymer product, thereby ensuring the drying effect of the cyanate prepolymer product; S2: As the cyanate prepolymer product progresses, the solvent and water attached to the cyanate prepolymer product will evaporate into a gaseous state, causing high pressure to be formed inside the drying barrel (1). The high-pressure steam inside the drying barrel (1) will enter the rectangular groove in the second groove block (4) through the U-shaped tube (5). The steam inside the rectangular groove will enter the left side of the cylindrical groove through the connecting tube (17) connected thereto, further causing high pressure to be formed inside the cylindrical groove to push the piston plate (28) to move, and at the same time, the gas on the other side of the cylindrical groove is discharged to the inside of the L-shaped tube (22) through the connecting tube (17) connected to the gas outlet (30). The movement of the piston plate (28) drives the first connecting rod (14) to move, and the movement of the first connecting rod (14) drives the lever (13) and the movable rod (12) to move. The movement of the movable rod (12) drives the flywheel (6) to rotate. When the lever (13) moves to contact the right lever plate (16), the lever plate (16) will move. 16) When the shaft (33) rotates, the shift plate (16) rotates, which drives the sliding column (35) to move leftward. The sliding column (35) moves leftward, which drives the second connecting rod (15) to move leftward. The movement of the second connecting rod (15) drives the reversing valve (29) to move leftward, so as to change the direction of the steam in the rectangular groove to enter the cylindrical groove from the right. At this time, the connecting pipe (17) on the left side of the cylindrical groove is connected to the air outlet (30), and the steam will enter the right side of the cylindrical groove through the rectangular groove, so that the piston plate (28) moves leftward and discharges the steam on the left side through the air outlet (30) to the inside of the L-shaped tube (22). In addition, due to the inertia of the flywheel (6), the flywheel (6) rotates counterclockwise when the second connecting rod moves leftward. When the shift rod (13) moves leftward and contacts the shift plate (16) on the left, the shift plate (16) on the left rotates. In the same way, the reversing valve (29) can be moved rightward. S3: The flywheel (6) can be rotated by reciprocating in sequence, and the rotation of the flywheel (6) drives the rotating shaft (10) to rotate, and the rotation of the rotating shaft (10) drives the small pulley (8) to rotate, and the rotation of the small pulley (8) drives the belt (7) to rotate, and the rotation of the belt (7) drives the large pulley (9) to rotate slowly, and the slow rotation of the large pulley (9) drives the turntable (24) to rotate slowly, and the rotation of the turntable (24) drives the hinged rod (25) to move, and the movement of the hinged rod (25) drives the vertical plate (26) to move, and the movement of the vertical plate (26) drives the sliding plate (31) to move up and down, and the sliding plate (31) moves up and down to allow the coolant inside the cooling cylinder (20) to circulate from the cooling jacket (23) through the two pipe bodies, and the coolant before and after is separated by the sliding plate (31), so as to ensure the condensation effect of the coolant on the steam, and finally the condensed steam will be converted into liquid and enter the collection bucket (21) to be collected. In summary, the steam of the dried cyanate prepolymer product can be collected by reciprocating in sequence.
