Description
Technical Field
The invention relates to the technical field of discharging devices, in particular to a gravity type negative pressure discharging device with a buffer cylinder assembly.
Background
Drying equipment is also known as dryers and dryers. The apparatus for carrying out the drying operation vaporizes the moisture (generally referred to as moisture or other volatile liquid components) in the material by heating to escape so as to obtain a solid material having a prescribed moisture content. The purpose of drying is for material use or further processing requirements. For example, the wood can be dried before making wood mould and woodware to prevent the product from deforming, and the ceramic blank can be dried before calcining to prevent the cracking of the finished product. In addition, the dried material is also convenient to transport and store, such as drying the harvested grain below a certain moisture content to prevent mildew. Because natural drying far cannot meet the requirements of production development, various mechanical dryers are more and more widely applied, the spray dryer belongs to one of drying devices, and the spray dryer still has wide application in chemical industry, light industry, food industry and other industries due to the special advantage that the spray dryer can directly prepare powdery products with uniform components from solution or suspension, and the application in the dye industry is the most common in the chemical industry.

The atomizers used are still of the three types pressure, centrifugal and air flow, but in recent years the use of centrifugal spray dryers has been on the rise. For true solution spray drying, it is worth noting that different hydrophilic solutes require different drying medium temperatures. For example, the water solution of inorganic salts such as strongly hydrophilic substances is evaporated and dehydrated mainly at the boiling point of the solution, and the gas leaving the tower at a temperature lower than 130 ℃ is difficult to operate. Although China has obvious gap compared with foreign countries, the manufacturing and operating levels of the spray dryer device are greatly improved.
