High-speed centrifuging spray dryer

Abstract

The invention discloses a high-speed centrifuging spray dryer. The high-speed centrifuging spray dryer comprises a high-temperature purifying chamber and a drying tower located at one side of the high-temperature purifying chamber, an air mixing chamber is arranged at one side of the high-temperature purifying chamber, an air supply tube is fixedly mounted at the top of the air mixing chamber, thetop end of the air mixing chamber is fixedly connected to one end of a spiral tube, the other end of the spiral tube is located in the drying tower, a coal-fired machine is arranged at one side, awayfrom the drying tower, of the high-temperature purifying chamber, a residue discharging machine, a combustion fan and a fire grate speed reducer are arranged at one side, away from the high-temperature purifying chamber, of the coal-fired machine, the combustion fan is located between the residue discharging machine and the fire grate speed reducer, the top inner wall of the drying tower is provided with an atomizer, and a fixing seat is fixedly mounted at the top of the drying tower. The high-speed centrifuging spray dryer has the advantages of realization of filtering out impurities in a material through a filter plate, convenience in increasing the filtering effect by continuous reciprocating movement of the filter plate, convenience in moving the filter plate out of a filtering box, convenience in removal of the impurities on the filter plate, simple structure, and easiness in use.

Description

Technical field [0001] The invention relates to the technical field of spray dryers, in particular to a high-speed centrifugal spray dryer. 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 size of the nozzle hole of the feed liquid pump can be adjusted to obtain the required spherical particles in a certain size ratio. The spray dryer is a type of continuous atmospheric pressure dryer. Sprayed into a mist to make it contact with hot air to be dried. It is used to dry some heat-sensitive liquids, suspensions and viscous liquids. It is also used to dry fuels, intermediates, soap powder and inorganic salts, etc., generally including electric heating drums. Air drying box, vacuum drying box, high-speed centrifugal spray dryer, aseptic spray dryer, the air is filtered and heated, and enters the air distributor at the top of the dryer. The hot air ente...
