Description

Technical Field

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

[0002] Isoprene is an organic compound, a colorless, volatile liquid, insoluble in water, soluble in most organic solvents such as ethanol and ether. It can be prepared by propylene dimerization and is used for synthetic rubber monomers, etc. The existing internal packing of the refining tower is fixed in blocks inside the refining tower, resulting in a reduction in the contact area between some inert solids and reactants or even an inability to contact with the reactants, thereby reducing the rate of preparing isoprene and increasing production costs. Patent documents have now been issued to improve this.

[0003] For example, Chinese patent CN215823089U discloses a refining tower for preparing isoprene, comprising a tower body, wherein a distributor is provided through the upper end of the tower body, a conical filler is provided at the inner upper end of the tower body, a plurality of evenly distributed rings are provided on the side wall of the conical filler, a stepped filler is provided inside the conical filler, a funnel-shaped filler is provided inside the tower body and at the lower end of the conical filler, a plate-shaped filler is provided between the funnel-shaped fillers, and a monitoring device is provided at the inner lower end of the tower body to increase the contact area between inert solids and reactants, thereby avoiding a reduction in the rate of preparing isoprene due to a reduction in the contact area between some inert solids and reactants or even a failure to contact the reactants, thereby improving the efficiency of isoprene and reducing production costs.

[0004] Although the above patent increases the contact area between inert solids and reactants to avoid the reduction of the contact area between some inert solids and reactants or even the inability to contact with the reactants, the conical fillers, stepped fillers, funnel-shaped fillers and plate-shaped fillers are complexly arranged, and the operation is too cumbersome when replacing the solid fillers. In addition, the distributor is fixed, resulting in the nozzle only distributing the liquid raw materials to fixed positions, and the distribution of the liquid raw materials is not uniform enough. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a refining tower for isoprene rubber production, which solves the problems that when replacing solid fillers, the operation is too complicated and the distributor is fixed, resulting in the nozzle only distributing liquid raw materials to fixed positions and the distribution of liquid raw materials is not uniform enough.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a refining tower for isoprene rubber production, comprising a refining tower body and a tower cover located on the top of the refining tower body, a mounting ring is fixedly connected to the upper part of the outer surface of the refining tower body and the outer surface of the tower cover, the tops of the two mounting rings are threadedly connected with a plurality of bolts through openings, connecting rods are fixedly connected to both sides of the top of the inner cavity of the tower cover, one end of the two connecting rods is fixedly connected to a connecting plate, the bottom of the connecting plate is fixedly connected to a fixing rod, the outer surface of the fixing rod is fixedly connected to a plurality of filling plates, the two sides of the top of the filling plate are fixedly connected to support plates, and the tops of the two support plates are fixedly connected to conical fillers.

[0007] Preferably, the top of the tower cover is fixedly connected with a fixing cylinder, the interior of the fixing cylinder is fixedly connected with a motor, the output shaft of the motor is fixedly connected with a rotating rod through a coupling, one end of the rotating rod passes through the tower cover and extends to the interior of the tower cover, and a distribution pipe is arranged inside the tower cover.

[0008] Preferably, a plurality of nozzles are connected below the outer surface of the distribution pipe, and a liquid delivery pipe is connected to the outer surface of the distribution pipe. One end of the liquid delivery pipe passes through the tower cover and extends to the outside of the tower cover.

[0009] Preferably, a rotating plate is fixedly connected to the inner surface of the distribution pipe, and one end of the rotating rod is fixedly connected to the top of the rotating plate.

[0010] Preferably, one end of the fixing rod is fixedly connected to a limiting plate, and both sides of the limiting plate are fixedly connected to supporting rings.

[0011] Preferably, a support block adapted to the support ring is fixedly connected below the inner surface of the refining tower body.

[0012] Preferably, the bottom of the refining tower body is connected to a drain pipe.
