Vibrating trough vibrating sieve device and screening method

Abstract

The invention discloses a groove-vibrating and sieve-vibrating device and a screening method. After dicumyl peroxide is crystallized and centrifuged, solid semi-wet powdery dicumyl peroxide is conveyed to a laboratory fluid bed dryer by the groove-vibrating and sieve-vibrating device for drying, and the dried high-purity dicumyl peroxide containing different particles and powder is conveyed to the next process to play a screening role in a conveying process.

Description

technical field [0001] The invention relates to a vibrating tank and sieve device, in particular to a dicumyl peroxide (dry) vibrating tank and sieve device. Background technique [0002] In chemical production, many kinds of raw materials, semi-finished products or finished products are in a solid state and need to be transported from one place to another. The transportation of solid materials must ensure efficiency and maintain the quality of materials. There are basically the following types of equipment: [0003] Belt conveying equipment can be conveying tools driven by belt rollers or chains. [0004] Bucket conveying equipment, using a circulating hopper to lift bulk solid materials upwards. [0005] Pneumatic conveying equipment directly uses airtight pipelines to convey solid materials with gas as power; because this conveying method has become a technical difficulty in dust treatment, it is not used in the device. [0006] Gravity conveying equipment directly reli...

AI Technical Summary

Problems solved by technology

However, the corrugated sidewall belt conveying only involves conveying, so the device needs to add equipment such as screening, so the equipment is many and complicated, and there are the following disadvantages: (1) Since dicumyl peroxide is a rubber crosslinking agent, Long-term transportation will cause the rubber to age easily and affect the service life of the equipment. The service life of the conveyor belt is only 3 months, and the belt must be replaced. The cost of a belt is about 60,000 yuan

During use, dicumyl peroxide powder will enter into the roller bearings of the guide conveyor wheel, causing damage to the bearings. Generally, the guide conveyor wheel bearings are replaced every 3 months, and the roller bearings are replaced every 6 months.

(2) Due to the aging of rubber, the fallen rubber particles are mixed into the finished product, which ultimately affects the product quality

(3) Due to uneven material delivery during the process of transporting dicumyl peroxide, there will be an instantaneous increase, resulting in equipment failure

(4) Small particles of dicumyl peroxide are prone to dust during the transportation process, which will affect the production environment

(5) Supporting sieving equipment, due to the layout of the equipment, the sieving machine cannot be selected to occupy a particularly large area, and its effective area often does not meet the full and complete sieving requirements, and the sieving efficiency is low

Bucket conveying also only involves conveying, so the device still needs to add equipment such as screening, and there are disadvantages: (1) The overload sensitivity is high, the material must be supplied evenly, and the bucket and chain are easily damaged

(2) The contact between the material and the mechanical transmission parts will cause friction between the material and the transmission parts, making the material black, which will not only seriously affect the product quality, but also cause damage to bearings and other components
