Spray drying machine used for solid dye production

Abstract

The invention provides a spray drying machine used for solid dye production. The spray drying machine used for solid dye production comprises a supporting pedestal plate, a drying tank, supporting columns, an atomizer, a dye liquid inlet pipe, a nozzle, a hot air conduit, a discharge valve, a blower fan, a cold air purifying filtering tank structure, an anti-blocking hand-operated material overturning sheet structure, a discharging airborne-dust-prevention cyclone separator structure, an ultrasonic vibration particle shaking-off ring structure, an air heating tank structure, a gas guiding connecting pipe, a secondary separation conduit, a collecting tank, an induced draught fan, and an exhaust gas discharge connecting pipe. According to the spray drying machine, a purifying tank, a sealingtank bovver, an air inlet pipe, a stainless steel pipe filter screen, a nylon filter screen, and a HEPA filter layer are adopted, so that it is beneficial for filtering impurity removing of dried air, and filtering purifying of particles or harmful gas in the air is realized; a hand-operated rocking bar, a material overturning sheet, a ball bearing, a hand-operated wheel, and a handle are adopted, so that it is beneficial for dredging and blocking prevention in discharge process of dried solid dye particles.

Description

technical field [0001] The invention belongs to the technical field of dye processing equipment, in particular to a spray dryer for solid dye production Background technique [0002] Drying equipment is also called dryer and dryer. The equipment used for drying operation, the moisture in the material (generally refers to water or other volatile liquid components) is vaporized and escaped by heating to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. For example, drying wood before making wooden molds and woodware can prevent product deformation, and drying ceramic blanks before calcination can prevent cracking of finished products. In addition, the dried materials are also convenient for transportation and storage, such as drying the harvested grains below a certain moisture content to prevent mildew. Since natural drying is far from meeting the needs of production development, var...
