Description

Technical Field

[0001] The present invention relates to the technical field of material drying, and more specifically, to an all-round drying system for preventing local material from being overheated, sticking and remaining. Background Art

[0002] Drying refers to the process of removing solvents and retaining solid content in some way; it usually refers to the process of introducing hot air to evaporate and remove the moisture in the material; according to the three ways of heat transfer: heat conduction, heat convection, and heat radiation, there are also three corresponding drying methods: drum drying, hot air drying, and far-infrared drying; material drying refers to the process of removing moisture from the material through heating, ventilation or other methods to make it reach a predetermined moisture content; this process is widely used in agriculture, industry, food processing and other fields to extend the storage period of materials, improve the quality of materials or prepare for subsequent processing.

[0003] Common material drying methods include hot air drying, microwave drying, vacuum drying, freeze drying, and solar drying; each drying method has its own applicable material types and specific advantages and disadvantages. Choosing a suitable drying method requires considering the characteristics of the material, the requirements of the final product, and the production cost. The drying process should be roughly divided into three stages for control: the first stage is the temperature rise preheating stage, the second stage is the high temperature heating and large amount of water evaporation stage, and the third stage is the furnace cooling stage.

[0004] However, in the second stage of high-temperature heating to evaporate a large amount of water, if the heat conduction is uneven, it is easy for a large amount of water to evaporate locally and concentrate on other parts of the material, causing the problem of local material overheating and adhesion residue, and also causing uneven drying; for example, in the prior art, "a multi-size granular material drying device" is a Chinese patent, and the authorization announcement number is CN116428828B; the space between the "inner cylinder" and the "outer cylinder" recorded therein is certain, and the heat conduction range is fixed. After the material enters the interior, if the material has a certain humidity and viscosity, there is a risk of adhesion between the "inner cylinder" and the "outer cylinder", causing partial accumulation of the material and uneven heat conduction. Therefore, in order to solve the above problems, a full-range drying system that prevents local material overheating and adhesion residue is proposed. Summary of the invention

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] The material is added into the inner drying cylinder, and the power provided by the power device is used to rotate inside and relative to the outer cylinder to dry the material inside the inner drying cylinder; during the synchronous rotation of the main drying and mixing rack and the inner drying cylinder, a driving member is used to drive and drive multiple smoothing rings to move back and forth periodically along the column direction of the inner drying cylinder; during the movement, the multiple smoothing rings scoop up the material on the inner surface of the inner drying cylinder and throw it into the air to mix the material, and the scattered material is conducive to heat conduction and also conducive to the evaporation of a large amount of water; the material thrown into the air uses multiple dehumidification holes to absorb the water vapor inside the material thrown into the air; the problem of overheating and adhesion residue of local materials is avoided, which is conducive to improving the uniformity of drying;

[0024] During the process of the inner drying drum rotating to dry the material, the through cavity is used to periodically inflate and deflate the stirring airbag, so that the stirring airbag expands periodically. After the stirring airbag expands, the material inside the inner drying drum will be pushed to the inner wall of the inner drying drum and spread flat, which promotes the movement of the material, promotes the release of moisture, and is conducive to the full contact between the material and the inner wall of the inner drying drum, thereby increasing the contact area with the heat source.

[0025] During the periodic forward and backward movement of multiple smoothing rings, the materials on the inner surface of the inner drying cylinder are scooped up and thrown into the air to mix the materials. The stirring airbags periodically expand to push the materials toward the inner wall of the inner drying cylinder and multiple smoothing rings. The smoothing rings push the materials toward the center of the inner drying cylinder and the stirring airbags push the materials outward to collide and mix the materials, and fully adjust the materials to achieve full heat conduction and full moisture release. It avoids the accumulation of some materials with a certain humidity and viscosity, which causes uneven heat conduction and causes local overheating and adhesion residue of materials.

[0027] During the macroscopic material drying process of the inner drying cylinder, the secondary drying tank is used to dispatch the material locally, so as to further promote the mixing, stirring and drying of the material; during this process, the material enters the secondary drying tank body, and the auger on the secondary drying material transfer assembly is used to transfer the material, and the material moves along the spiral material transfer and drying channel. At the same time, multiple heating columns are used, and hot air is periodically introduced into the heating airbag to achieve accurate all-round drying of the material inside the material transfer and drying channel; in the process of the heating airbag being periodically filled with hot air and expanding, on the one hand, it can squeeze the material inside the material transfer and drying channel, promote the lateral mixing of the material under the auger transmission state, and improve the uniformity of drying; on the other hand, the expansion of the heating airbag can clean the heating column that is inserted into the material for heating through the storage hole, so as to ensure the heating effect of the heating column, and also avoid the accumulation and overheating of the material sticking to the heating column.
