Description

Hot air double-circulation drying equipment

Technical Field

The utility model belongs to the technical field of drying equipment, concretely relates to heated air dual cycle 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.

SUMMERY OF THE UTILITY MODEL

To the problem that exists, the utility model provides a hot-blast dual cycle drying equipment is evenly dry when being applicable to big batch material, avoids unnecessary energy loss.

The technical scheme of the utility model is realized like this: 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.

The utility model discloses a drying time of material has effectively been shortened to the dry mode of inner heat upper and lower dual cycle air current combination, has promoted dry homogeneity and quality of material.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to 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 a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
