Abstract

The invention relates to a feeding and dispensing device, mainly comprising shell of storage house, middle shell, bottom flange, rotary brush, filter screen, agitator, floating disk module, rotary metering disk, fixed disk, carrying segment module and power driving part. Motor and reducer of power driving part are connected with driving shaft with each other and on the driving shaft the rotary brush, the agitator and the rotary metering disk are connected. The filter screen is fixed on the middle shell and the floating disk module is set between the agitator and the rotary metering disk. The fixed disk is set under the rotary metering disk and the carrying segment module is set under the bottom flange. The invention realizes the continuous accurate feeding and dispensing of catalyzer in polymerization reaction and it can be used in petrochemical industry, food and medicine industry. The invention is provided with compact structure, easy utilization and maintenance.

Description

technical field [0001] The invention relates to a dosing device, especially a device capable of continuously and accurately dosing catalysts in a polymerization reaction. Background technique [0002] In the polymerization reaction of petrochemical equipment, in the production process of food, pharmaceutical and other industries, the catalyst and additive dosing device are indispensable equipment. Taking the petrochemical polyethylene equipment as an example, the types of catalysts and the amount of additives are different. The type and quality of products produced vary widely. At present, my country's continuous polymerization ethylene plant, process and key equipment are all monopolized by foreign countries, the reason is that the process and equipment are relatively complicated. [0003] At present, most of the catalysts used online in my country are fed by screw conveying method, and the amount of catalyst to be added is calculated according to the production time; in o...
