Catalyst feeding equipment for producing polypropylene

Abstract

The invention discloses a catalyst feeding device for producing polypropylene. Its structure is provided with a feeding cylinder, a driving machine, a preparation barrel, a driving machine, a transmission wheel, and a support seat. The driving machine is installed at the partial top of the feeding cylinder and matched , the preparation barrel is located on one side of the feeding barrel, and the driving wheel is connected to the transmission wheel under the drive and is movable. , the telescopic nature of the variable rod matches its lifting displacement, the spherical structure of the auxiliary ball, the auxiliary variable rod has different telescopic inclinations, which is conducive to the small hinge rotation of the moving block, and reduces the jamming with the catalyst Force, there is a certain heavy pressure through the inner heavy ring, and under the elastic cooperation of the spring through rod, it is connected with the displacement of the outer contact ring, which further assists the flexible change of the changing rod, and facilitates the displacement of the moving block with the cooperation of the mobilization device. , Flexible adjustment of the bore width.

Description

technical field [0001] The invention belongs to the field of polypropylene, and more specifically relates to a catalyst feeding device for producing polypropylene. Background technique [0002] Polypropylene is an excellent thermoplastic synthetic resin with heat resistance, insulation, plasticity and other properties. It is a polymer synthesized after chemical addition polymerization using propylene as raw material. The excellent properties of polypropylene make it widely used in many fields Development and application, people often need to use catalyst feeding equipment in the production of polypropylene, so that the catalyst can improve the chemical reaction efficiency of polypropylene, which is beneficial to accelerate the production speed of polypropylene. [0003] Based on above-mentioned inventor's discovery, existing production polypropylene catalyst feeding equipment has the following deficiencies: [0004] Since the reaction of the catalyst in the reactant is carr...

AI Technical Summary

Problems solved by technology

[0004] Since the reaction of the catalyst in the reactant is carried out on the surface of the catalyst, its surface area plays an important role in dispersing the active components of the catalyst. During the process of being fed, the catalyst needs to be conveyed in a separate spiral, controlled by the opening of the catalyst storage tank. Spherical catalysts fall into the upper barrel by grading, usually with a fixed caliber, but the catalyst will have carbon deposits during use, and its volume will expand, and it is easy to get stuck at the drop port, resulting in longer intervals in catalytic feeding and carbon deposits At the same time, it also reduces the effective catalytic surface of the catalyst, resulting in lower catalytic efficiency
