Stirring device for fully stirring catalyst and degraded plastic organisms

Abstract

The invention relates to the technical field of bio-based materials, and discloses a stirring device for fully stirring a catalyst and degraded plastic organisms. The stirring device comprises a stirring mechanism, a funnel is movably mounted above the stirring mechanism, and a main rod is movably mounted below the funnel. By using the catalyst of a lower grinding disc, the weight is reduced, the gravity is reduced, the elastic force of a spring pushes a piston rod to move upwards in an air cylinder and drives the lower grinding disc and the catalyst to move upwards. Friction force between an upper grinding disc and the lower grinding disc is kept, the fineness of the catalyst is improved, and then powder of the catalyst falls into the periphery of a stirring box through vent holes by means of wind power of a fan. The sufficient stirring rate between the catalyst and the biological plastic is improved. A threaded rod rotates to drive a connecting block to move upwards, so that a support shaft pulls a supporting rod to be folded. At the moment, the stirring mechanism is shrunk, the bioplastics are prevented from being stacked above the stirring mechanism when being fed, the stirring time is shortened, and the stirring efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bio-based materials, in particular to a stirring device for fully stirring catalysts and degrading plastic organisms. Background technique [0002] Bio-based materials refer to biopolymer materials or monomers obtained from renewable raw materials through biotransformation, and then further polymerized to form polymer materials. Bio-based materials include bio-based platform compounds, bioplastics, etc. [0003] After a large number of bioplastics are produced, it is necessary to accelerate the decomposition rate of this type of garbage. After the bioplastics are crushed, catalysts are evenly added to them, and photocatalysis, a non-polluting catalytic approach, is used to accelerate the decomposition rate of bioplastics. The existing photocatalytic degradation device cannot achieve uniform mixing of plastics and catalysts, and at the same time, with the grinding and use of the catalyst, the dosage is de...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a stirring device for fully stirring the catalyst and degrading plastic organisms. The stirring device can be contracted, which is convenient for putting the bioplastics into the bottom of the stirring box in the early stage, and fully grinds the catalyst. The advantage of fully stirring the catalyst with bioplastics solves the problem that the existing photocatalytic degradation device cannot realize the uniform mixing of plastics and catalysts, and at the same time, as the catalyst is ground and used, its dose is reduced, and the grinding devices on both sides are fixed, which may Insufficient grinding in the middle of use, insufficient catalyst grinding, resulting in reduced catalyst utilization and reduced catalytic efficiency

The position of the stirring roller is fixed, which will cause bioplastics to accumulate on the top of the stirring device for a long time when they are put in, which increases the stirring time and reduces the stirring efficiency.
