Multifunctional Blast Dryer

Abstract

The invention discloses a multifunctional blast drier which is of a cylindrical casing. The casing comprises a heating blast area, a material changing area and a drying area, wherein the heating blast area is of a cylindrical cabin body; the material changing area and the drying area are combined into a cylindrical cabin boy; the outer side of the smaller cylindrical cabin body is coated with the larger cylindrical cabin body; the drying area is of a sealed cabin body; the material changing area is of an opened cabin body; heat-insulating sealing doors are arranged between the material changing area and the drying area; an air current distribution channel is formed in the top of the casing; the middle of the air current distribution channel communicates with the heating blast area; the air current distribution channel communicates with the drying area through air current distributing boards; and the material changing area and the drying area on the cylindrical cabin body are of multiplayer structures. According to the multifunctional blast drier disclosed by the invention, by adopting an internal heat and circulating air current combined drying mode, heat sources and heat energy are prevented from directly contacting with an external casing, and the heat energy is recycled in the casing, so that the loss is avoided; the device is of a multilayer structure and can be used for simultaneously drying large-batch materials; an operator can accurately grab materials at various positions in the casing while performing drying operation, so the convenience and the quickness are realized.

Description

technical field [0001] The invention relates to the field of drying equipment for chemical production, in particular to a multifunctional blast dryer. Background technique [0002] Drying equipment is one of the necessary production equipment in the field of chemical production. It mainly transfers heat from high-temperature heat sources to wet materials in various ways, so that the moisture on the surface of the materials is vaporized and dissipated to the external space, so that moisture appears on the surface and inside of the materials. The difference in content; the internal moisture diffuses to the surface and vaporizes, so that the moisture content of the material is continuously reduced, and the overall drying of the material is gradually completed. [0003] Due to the limitations of its own structure, the drying equipment currently on the market has its heat source set outside or around the equipment. During the drying process, part of the heat energy generated by t...

Problems solved by technology

[0003] Due to the limitations of its own structure, the drying equipment currently on the market has its heat source set outside or around the equipment. During the drying process, part of the heat energy generated by the heat source in the device has not been in contact with the material during the transfer process. , it directly spreads to the outside of the drying equipment, and the heat energy cannot be fully utilized; the overall energy utilization rate of the device is low

[0004] At the same time, for daily chemical production, it may be necessary to dry a large number of groups of materials at one time at the same time. The drying time of different materials is different. During the drying process, materials need to be continuously added or taken out. Or during the removal operation, it is necessary to open the airtight door of the drying device many times, resulting in a large amount of energy loss

At the same time, because a variety of materials are stored in the large drying device, when taking the materials placed inside the shell, the operator cannot directly open and take them out. It is necessary to find and adjust the position of the materials in the drying box, which is time-consuming and laborious, and the operation is very inconvenient.
