Description
Technical Field
The invention belongs to the technical field of drying equipment, and particularly relates to hot air double-circulation drying equipment.
Background
The hot air drying equipment is one of necessary equipment in the field of material drying, and mainly transfers heat from a high-temperature heat source to wet materials in various modes, so that moisture on the surfaces of the materials is vaporized and dissipated to an external space, the difference of moisture content appears on the surfaces and the inside of the materials, the moisture in the inside is diffused and vaporized towards the surfaces, the moisture content of the materials is continuously reduced, and the drying of the whole materials is gradually completed.
The existing hot air drying equipment has the defects that due to the limitation of the structure, the heat source circulation mode of the existing hot air drying equipment is an upper circulation mode, a lower circulation mode or other modes, in the drying process, materials are gradually dried from the upper part to the lower part or gradually dried from the lower part to the upper part in the transfer process of heat generated by a heat source in the device, the materials are not integrally dehydrated and dried, and heat energy cannot be fully utilized, so that waste is caused. If the amount of the dried materials is increased, the materials can not be uniformly dehydrated and even mildewed.
Disclosure of Invention
Aiming at the problems, the invention provides hot air double-circulation drying equipment which is suitable for uniformly drying large-batch materials at the same time and avoiding unnecessary energy loss.
The technical scheme of the invention is realized as follows: a hot air double-circulation drying device comprises a heat supply chamber and a material drying chamber, wherein the heat supply chamber is arranged in the heat supply chamber, a material rack and a moisture exhaust window are arranged in the material drying chamber, an air inlet chamber is arranged between the heat supply chamber and the material drying chamber, an upper channel and a lower channel which are communicated with the heat supply chamber and the material drying chamber are respectively arranged above the top and below the bottom of the air inlet chamber, one side wall of the air inlet chamber is communicated with the material drying chamber through the hot air window, the other side wall of the air inlet chamber is communicated with the heat supply chamber through an air guide fan, and the air inlet chamber is provided with an air inlet window which can be communicated with the outside.
Preferably, the side wall of the air inlet chamber close to one side of the material drying chamber is provided with an observation window, so that the drying condition of the material can be observed conveniently.
According to the invention, the drying time of the material is effectively shortened and the uniformity and quality of material drying are improved by an internal-heat up-down double-circulation airflow combined drying mode.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a view from a-a in fig. 1.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The hot air dual-circulation drying device shown in fig. 1 and 2 comprises a heat supply chamber 1 and a material drying chamber 2, wherein a heat supply device 11 is arranged in the heat supply chamber 1, a material rack 21 and a moisture exhaust window (not shown) are arranged in the material drying chamber 2, an air inlet chamber 3 is arranged between the heat supply chamber 1 and the material drying chamber 2, an upper channel 4 and a lower channel 5 which are used for communicating the heat supply chamber 1 and the material drying chamber 2 are respectively arranged above the top and below the bottom of the air inlet chamber 3, one side wall of the air inlet chamber 3 is communicated with the material drying chamber 2 through a hot air window 31, the other side wall of the air inlet chamber 3 is communicated with the heat supply chamber 1 through an air guide fan 12, the air inlet chamber 3 is provided with an air inlet window 32 which can be communicated with the outside, and an observation window 33 is arranged on one side wall.
The working principle and the working process are as follows: the material to be dried is placed on the material frame 21, a certain gap is formed between the upper portion and the lower portion of the material drying chamber 2, the heating device 11 and the air guide fan 12 are started, the air guide fan 12 sucks external air and air in the material drying chamber 2 into the heating chamber 1, the external air and the air are heated by the heating device 11 and then enter the material drying chamber 2 through the upper channel 4 and the lower channel 5, and the hot air moves 6 to dry the material from top to bottom and from bottom to top simultaneously, so that a drying mode with simultaneous up-and-down double circulation of air flow is formed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
