thirdly, closing the third electromagnetic valve (7) and opening the first electromagnetic valve (44), thereby effectively opening the air outlet (1b) on the tank body (1) and closing the air inlet (1 c); then, the vacuum pump (42) is started, and the vacuum pump (42) is utilized to vacuumize the tank body (1); after a certain vacuum degree is obtained, closing the first electromagnetic valve (44) to ensure that the tank body (1) keeps a certain vacuum degree, and simultaneously closing the vacuum pump (42); then the electric heating plate (8) is opened, and high temperature is formed in the tank body (1) to crack the rubber; when the rubber is cracked, the servo motor (61) is started, the stirring paddle (63) is driven to rotate by the servo motor (61), and the stirring paddle (63) with an irregular shape is used for continuously cutting the stirred rubber, so that the cracking of the rubber is accelerated, and the cracking time is saved;
fourthly, after the cracking is finished and the temperature of the tank body (1) is cooled to a certain degree, opening a third electromagnetic valve (7) to enable the air in the tank body (1) to enter and remove the vacuum state of the inner cavity of the tank body (1); then, opening a second electromagnetic valve (52), and arranging a collecting device at the bottom of the discharge pipe (51) to collect a product;
the top end of the tank body (1) is provided with a sealing opening and closing mechanism (3), the side wall of the tank body (1) is provided with a vacuumizing mechanism (4), the tank body (1) can be pumped to a certain vacuum degree, and the melting point of rubber is reduced; meanwhile, the heating temperature can be reduced, and the potential safety hazard is reduced; the sealing cover (31) is connected with a stirring mechanism (6) which penetrates into the tank body (1), so that the cracking speed can be increased and the cracking time can be shortened in the process of heating and melting rubber; the top end of the tank body (1) is provided with a sealing opening and closing mechanism (3), and the side wall of the tank body (1) is connected with a climbing support mechanism (2), so that a worker can climb and feed conveniently; and the support of the whole tank body (1) is more stable and firmer, and the tank body is prevented from toppling over.
