Granulation device for 4-tert-butylcatechol

Abstract

The invention discloses a granulation device for 4-tert-butylcatechol. The granulation device comprises a cabinet, an adhesion assembly, a pre-pressing assembly, a granulation assembly, a throttle assembly, a pushing assembly and a vibration assembly, wherein the adhesion assembly is mounted on one side of the cabinet; the pre-pressing assembly is mounted at the top of the cabinet; the granulationassembly is mounted on the other side of the cabinet; the pushing assembly and the vibration assembly are mounted in the cabinet; the adhesion assembly comprises a water tank, a water pump and an atomizer, the water tank is arranged on one side of the cabinet, and one side of the water tank is connected with one end of the water pump through a connecting pipe. The granulation device has the advantages that material extrusion is facilitated, and material scattering is prevented; materials are extruded repeatedly into blocks, and granule forming is facilitated; material pushing is facilitated;the materials are prevented from adhering to a fixed plate and are convenient to push; granulation is facilitated; flow rate of a liquid can be reduced, and the quantity of sprayed adhesive is reduced.

Description

technical field [0001] The invention relates to the technical field of granulation equipment, in particular to a p-tert-butylcatechol granulation device. Background technique [0002] P-tert-butylcatechol is a white or light yellow powder with the molecular formula C 10 h 14 o 2 , Soluble in methanol, carbon tetrachloride, benzene, ether, ethanol and acetone. It is derived from the reaction of tert-butanol and catechol or from the reaction of catechol and isobutene. It can be used as heat sensitive polymerization inhibitor. [0003] In the production process, from the perspective of facilitating firing and solid-state reaction, it is hoped to obtain ultra-fine raw material particles, but the finer the powder, the larger the specific surface area, the worse the fluidity, and it is not easy to be filled uniformly during dry pressing Molds often have the problems of voids, non-dense corners, lamellar cracks, and elastic failures in molded parts. Granulation processes are o...

AI Technical Summary

Problems solved by technology

[0004] However, the existing p-tert-butylcatechol granulation device has the following defects: it is not conducive to the extrusion of the material, and it cannot prevent the material from scattering; the material cannot be squeezed multiple times, which is not convenient for particle formation; It is easy to stick and not easy to push; it is not conducive to granulation; it is not conducive to reducing the flow rate of the liquid, and at the same time it cannot reduce the amount of sprayed adhesive; in view of this defect, it is very important for us to design a p-tert-butylcatechol granulation device Necessary
