Problems solved by technology

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a hot air recycling heating and drying equipment that alternately heats up and down. The drying equipment can realize the drying of hot air alternately up and down, effectively avoiding the uneven drying effect caused by drying in one direction. The drying is more uniform, and the efficiency of drying is also improved accordingly.

[0051] A hot air recovery method for heating and drying alternately up and down, the steps are as follows:

[0052] 1) Provide the above-mentioned a kind of hot air recycling heating and drying equipment alternately up and down;

[0053] 2) The second valve blocks the fourth pipeline, and at the same time, the first valve blocks the side of the hot air intersection, the hot air enters the hot air intersection from the air inlet pipeline, and enters from the bottom of the drying box through the second pipeline Dry the product to be dried, then flow out through the second pipeline, and then enter the air inlet pipeline through the third pipeline after flowing out;

[0054] 3) The second valve blocks one side of the hot air intersection, and at the same time, the first valve blocks the third pipeline, the hot air enters from the air inlet pipeline to the hot air intersection, and enters from the top of the drying box through the first pipeline Dry the product to be dried, then f...

Abstract

The invention discloses hot air recovery up-down alternative heating-drying equipment and a method. The problems that in the prior art, to-be-dried materials are low in drying speed and heat energy iswasted are solved, and the equipment and the method have the advantages of good drying uniformity and high drying speed. According to the scheme of the equipment, the hot air recovery up-down alternative heating-drying equipment comprises a drying cabinet, at least one drying layer is arranged in the drying cabinet, and to-be-dried materials are arranged on the drying layer; and a first pipelineis arranged at the bottom of the drying cabinet, a second pipeline is arranged at the top of the drying cabinet, the first pipeline and the second pipeline are crossed to form a hot air intersection,the hot air intersection is connected with an air inlet pipeline, a third pipeline is arranged between the second pipeline and the air inlet pipeline, a fourth pipeline is arranged between the first pipeline and the air inlet pipeline, a first valve is movably arranged between the hot air intersection and the second pipeline, and a second valve is movably arranged between the hot air intersectionand the first pipeline.

Description

technical field [0001] The invention relates to the field of drying and drying, in particular to a hot air recycling equipment and method for alternately heating and drying up and down. Background technique [0002] In the existing drying equipment, because the hot air is usually in a single direction, for the stacked objects to be dried, the hot air enters from a single direction, especially from the bottom to the top, and the temperature of the hot air is gradually reduced. The dried objects and the upper layer of dried objects are not easy to be dried, resulting in slow drying speed, and it is easy to waste more heat energy for the drying of the upper layer to be dried, and although the temperature of the hot air after drying decreases, it still has a certain The existing technology does not recycle this part of heat energy, resulting in low drying efficiency. [0003] Therefore, improving the drying efficiency of the drying equipment is an urgent problem to be solved at...
