Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a magnesium sulfate spray granulation device. Background Art

[0002] As an important raw material, magnesium sulfate is widely used in many fields such as medicine, agriculture and chemical industry. There are two main methods for producing magnesium sulfate: wet method and dry method. The wet method of producing magnesium sulfate requires chemical reaction, the reaction process is relatively complicated, and a large amount of wastewater and waste will be generated, causing great pollution to the environment. In contrast, the dry method of producing magnesium sulfate is simpler and more environmentally friendly. Therefore, more and more manufacturers are currently using the dry method to produce magnesium sulfate. In the process of dry method of producing magnesium sulfate, spray granulation technology is an important process link. Through spray granulation technology, liquid magnesium sulfate can be evenly atomized and sprayed in high-temperature hot air, so that it can be quickly dried to obtain a finished product.

[0003] According to the application number "CN202321971439.X", uniform spraying can be achieved by evenly distributing atomizing nozzles, and the angle of inclination can realize the upward spraying of liquid, increase the travel of droplets, thereby extending the contact time with hot air and improving drying efficiency. In addition, the vertical setting of the hot air duct also achieves the effect of long contact time with hot air, thereby improving the efficiency of spray granulation; the fixed screen inside the box can directly and effectively screen the magnesium sulfate particles, so as to obtain products that meet the requirements, saving additional screening procedures and improving processing efficiency.

[0004] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: although the position of the nozzle is set upward to increase the falling time, so that the liquid material can better contact with the hot air and react, the increased time is approximately equal to the time required for the nozzle to spray the liquid material to the top of the box body. Since the nozzle is close to the top of the box, the extended time is shorter and the delay effect is poor. Utility Model Content
