Abstract

The invention discloses a spray dryer. The spray dryer comprises a discharging opening, an air inducing system, a feeding system, an air supply system, a drying chamber and a machine body. The upper part of the machine body is a cylinder; the lower part of the machine body is a conical cylinder; the discharging opening is formed in the bottom of the machine body; the air inducing system is provided with a water cooling device, and an exhaust fan is arranged at the top of the machine body and provided with a frequency converter; and the feeding system is provided with a material pumping pump and a purifying barrel, the purifying barrel is in threaded connection with a material liquid tank, an electric heating pipe is electrically connected with an electric heater, an air blower is providedwith an air volume controller, and an air filter screen is arranged between the electric heating pipe and the air blower. The spray dryer has the beneficial effects of being simple in structure, convenient to operate and high in drying efficiency; the adaptability to materials is high, and a cold drying mode and a hot air drying mode can be switched; the strong cyclone in the conical cylinder ensures the drying uniformity of a feed liquid in the drying process; and the design of the frequency converter and the air volume controller ensures the stability of negative pressure in the machine body.

Description

technical field [0001] The invention relates to a spray dryer, which belongs to the technical field of dryers. Background technique [0002] The spray dryer is a device that can complete drying and granulation at the same time. According to the process requirements, the pressure, flow rate and nozzle size of the liquid pump can be adjusted to obtain spherical particles of a certain proportion. It is a kind of continuous atmospheric pressure dryer. Use special equipment to spray the material liquid into mist and make it dry in contact with hot air. A common term for drying heat-sensitive liquids, suspensions and viscous liquids. [0003] Due to the large gap between the development of materials in my country and foreign countries, the cost of high-quality synthetic steel used in the production of spray drying equipment in my country is relatively high, which is unacceptable to manufacturers, so manufacturers use relatively cheap carbon steel as raw materials for production...
