Stirring device with built-in pins in desulfurization machine

Abstract

The invention discloses a stirring device with built-in pins in a desulfurization machine. The stirring device is provided with a machine barrel (1), double-transmission screws (2), built-in pins (3), a feeding port (4) and a discharging port (5), and is characterized in that a sizing material enters the machine barrel (1) from the feeding port (4) and is conveyed to the discharging port (5) step by step through the double-transmission screws (2), five rows of the built-in pins (3) are arranged at the tail ends of the second-layer double-transmission screws (2) and the fourth-layer double-transmission screws (2) respectively, four built-in pins are arranged in each row, the rubber powder is continuously scattered and rearranged in the flowing direction after passing through the built-in pins (3), the secondary stirring process of the rubber powder is achieved, and under the conveying action of the double-transmission transmission screws (2), the scattered rubber powder is pushed to enter the next section of transmission screws to be continuously heated and desulfurized. Therefore, the rubber powder is secondarily stirred in the desulfurization machine, the desulfurization uniformity is improved, and the product quality is stabilized.

Description

technical field [0001] The invention relates to a desulfurization process of a desulfurizer in the reclaimed rubber industry. Background technique [0002] In the process of desulfurization and regeneration of waste rubber using a desulfurizer, since the desulfurizer relies on two relatively rotating screw conveying equipment, the desulfurization regeneration is completed under heating conditions. In this process, since the rotation of the screw blade mainly plays the role of screw conveying, the desulfurized rubber powder is added into the barrel of the desulfurizer after batching and stirring, and is transported forward along the direction of screw blade rotation. During the transmission process, according to the fluid theory, The flow velocity of rubber powder near the top, middle, and bottom of the screw blades will be different. The top flow velocity is the fastest, resulting in laminar flow, short heating time, and incomplete desulfurization, resulting in unstable qual...

In this process, since the rotation of the screw blade mainly plays the role of screw conveying, the desulfurized rubber powder is added into the barrel of the desulfurizer after batching and stirring, and is transported forward along the direction of screw blade rotation. During the transmission process, according to the fluid theory, The flow velocity of rubber powder near the top, middle and bottom of the screw blades will be different. The flow velocity at the top is the fastest, resulting in laminar flow, short heating time, and incomplete desulfurization, resulting in unstable quality of the final product.
