Description
Technical Field
The invention relates to a structure of a dry spraying machine, which is invented aiming at the internal structure of the dry spraying machine.
Background
The principle of the drying sprayer is that external air is heated and purified by a hot air supply device and then pumped into the drying sprayer, then the liquid or thick viscous liquid is sprayed into the drying sprayer in an atomizing or extremely small liquid droplet mode by a high-pressure nozzle (or a centrifugal atomizing device), at the moment, the atomized or extremely small liquid droplets and hot air generated by the hot air supply device are combined with each other, the hot air enables the moisture of the liquid to be evaporated, the liquid is rapidly dried in the hot air to form spherical solid powder, then the rapidly dried coarse-particle solid powder is discharged from an outlet, and the fine solid powder and the air in the drying sprayer are pumped to the outside together, and a next-stage process is carried out.
The general dry spraying machine comprises a feeding system, a spraying system, an air supply system and a product transportation system, wherein the feeding system is connected with the spraying system, the air supply system supplies hot air to the dry spraying machine, then the feeding system conveys spraying liquid to the spraying system of the spraying system through a high-pressure pump, the spraying system changes the spraying liquid into a spraying shape to be dispersed, the spraying liquid is combined with the hot air in the dry spraying machine and evaporates moisture to form solid powder, then an air blower of the product transportation system extracts air and the solid powder in the dry spraying machine, a cyclone separator screens the particle size of the solid powder, and finally the screened powder is discharged through a rotary valve below the cyclone separator to obtain finished powder. The above-mentioned dry spraying machine is an important machine in the current industry, and has the advantages of short drying time, capability of drying highly heat-sensitive substances, rapid drying of solid powder by liquid through the design and control of drying conditions, automatic control of liquid spraying operation, rotary spraying and the like, and drying spraying in a single step from a liquid, slurry or thin paste by spraying into the dry spraying machine for drying, which can obtain solid powder, and the dry spraying machine can be combined with the functions of other evaporators, pulverizers and grain selecting crystallizers to simplify the manufacturing process, so the dry spraying machine has become an important drying system in the chemical industry at present.
However, when the drying sprayer evaporates the liquid to form solid powder, many solid powder often sticks to the inner barrel wall of the drying sprayer, generally, if the liquid is milk powder formed by evaporation, the solid powder is not easy to stick to the barrel wall, but if the liquid is clay or liquid containing saccharide, the solid powder easily sticks to the barrel wall of the drying sprayer, because the spraying system sprays the liquid into the drying sprayer and the hot air supply device also sends hot air into the drying sprayer, at this time, the temperature of the barrel wall of the drying sprayer is lower than the temperature of the internal air, when the liquid touches the barrel wall of the drying sprayer, the liquid sticks to the barrel wall, the powder after liquid evaporation cannot be discharged along with the internal air and still sticks to the barrel wall, when the liquid sticks too much, the powder falls into hard blocks and does not affect the quality, if the surface of the barrel wall in the conventional drying and spraying machine is polished, the evaporated solid powder is more easily adhered to the surface when the liquid touches the surface, and the powder preparation efficiency of the drying and spraying machine is further influenced.
In summary, the present inventors have conducted extensive research and development to provide a dry spraying machine structure, in which a gap is formed between an outer housing and an inner housing, when a hot air supply device delivers hot air from the outside to the dry spraying machine, the hot air enters the gap to increase the temperature of the inner housing, and then the hot air enters the inner housing to combine with the liquid and evaporate the liquid, wherein when the liquid touches the bucket wall, a vapor film is generated between the liquid and the bucket wall due to the temperature of the bucket wall being higher than the temperature of the air inside, so that the powder of the liquid will not stick to the bucket wall after the moisture of the liquid evaporates, thereby increasing the usage efficiency of the dry spraying machine.
