Technical Field

[0001] The utility model application relates to the technical field of recovery towers, in particular to a solvent recovery tower for isoprene rubber production. Background Art

[0002] Isoprene rubber is a high-performance rubber used in tire production. It is widely used in the tire manufacturing industry for its stable chemical properties. It has good elasticity, cold resistance (glass transition temperature -68°C) and high tensile strength. Its resistance to cuts and tears under oxidation and multiple deformation conditions is higher than that of natural rubber. It is a general-purpose synthetic rubber with excellent performance. It is mainly used in tire production. Except for aviation and heavy-duty tires, it can replace natural rubber.

[0003] A large amount of organic solvents are used in the production of isoprene rubber. These solvents are generally recovered by distillation through recovery towers. However, when the current recovery towers recover the solutions, the impurities in the solutions are often retained inside the recovery towers. The presence of these impurities will reduce the subsequent distillation recovery efficiency of the solution. At the same time, the closed design of the recovery tower makes it inconvenient to recover these impurities. Summary of the invention

[0004] In order to solve the problem that when the current recovery tower recovers the solution, impurities in the solution are often retained in the recovery tower, the presence of these impurities will reduce the subsequent solution distillation recovery efficiency, and the closed design of the recovery tower makes it inconvenient to recover these impurities, the utility model provides a solvent recovery tower for isoprene rubber production to solve the above problems.

The sealing rods extend out of the top end of the recovery tower body, and a transmission plate is fixed to the top end of the two sealing rods. A cylinder is fixed to the top end of the recovery tower body, and the output end of the cylinder is fixedly connected to the top end of the transmission plate.

[0008] Furthermore, a spring is provided at the bottom end of the inner recycling bucket, one end of the spring is fixedly connected to the bottom end of the inner recycling bucket, and the other end of the spring is fixedly connected to the bottom end of the outer recycling bucket.

[0010] Furthermore, a slide plate is fixed on one side of the transmission plate, a limit plate is fixed on the bottom end of the slide plate, and a slide groove matching the shape of the limit plate is fixed on one end of the outer side of the recovery tower body close to the limit plate.

[0011] Furthermore, the inner radius of the limit plate is the same as the outer radius of the recovery tower body, and the side of the limit plate close to the recovery tower body is in contact with the outer side of the recovery tower body.

[0012] Furthermore, the limiting plate is fan-shaped, and a base is fixed directly below the recovery tower body.

[0014] 1. In the utility model, a driving motor is arranged on the side of the recovery tower body, and the driving motor drives three outer recovery barrels to enter the recovery tower body in turn for distillation recovery, so that the staff can clean the impurities in another inner recovery barrel while the solution in the inner recovery barrel of the recovery tower body is distilled, and the new solution to be processed is placed in the other inner recovery barrel, which solves the problem that when the current recovery tower recycles the solution, the impurities in the solution are often retained in the recovery tower, and the presence of these impurities will reduce the subsequent solution distillation recovery efficiency.

A cylinder 12 is fixed at the top end of the recovery tower body 1, and the output end of the cylinder 12 is fixedly connected to the top end of the transmission plate 13, so that the recovery tower body 1 and the outer recovery barrel 5 are sealed.

[0026] Specifically, a sealing ring is provided on the top of the sealing rod 14, a groove with the same shape as the sealing ring is provided on the top surface of the recovery tower body 1, and a sealing rubber is provided inside the groove, a slide plate 15 is fixed on one side of the transmission plate 13, a limiting plate 16 is fixed on the bottom end of the slide plate 15, and a slide groove 17 matching the shape of the limiting plate 16 is fixed on one end of the outer side of the recovery tower body 1 close to the limiting plate 16.
