Heat cycle type energy-saving drying equipment

Abstract

The invention provides heat cycle type energy-saving drying equipment and belongs to the field of drying. The heat cycle type energy-saving drying equipment comprises an outer box, a plurality of inner boxes arranged on the upper portion of the interior of the outer box and an electromagnetic heating part arranged on the lower portion of the interior of the outer box; the outer box is provided with a plurality of through holes; grooves corresponding to the through holes are formed in the inner boxes; the side surface of each groove is provided with a plurality of air outlets; air delivery pipes communicating with the air outlets are disposed in the corresponding inner boxes; the electromagnetic heating part is arranged at the other end of the air delivery pipes; the electromagnetic heatingpart comprises a heating iron pipe arranged outside the air delivery pipes in a sleeving mode and a conducting wire which is arranged outside the heating iron pipe in a surrounding mode and connectedwith a high-frequency power supply; the air delivery pipes are connected with the blowing end of a high-pressure fan; and the outer box is provided with air suction boxes used for dividing the innerboxes and sucking air in the inner boxes, and the air suction boxes are connected with the air suction end of the high-pressure fan through an air suction pipe. The heat cycle type energy-saving drying equipment can achieve fast drying of wet materials, moreover heat cycle utilization is achieved, the energy loss is reduced, a dry-wet contact interface of the equipment is coated with an anti-corrosion coating, the service life of the equipment is prolonged, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a thermal cycle energy-saving drying equipment. Background technique [0002] Since ancient times, humans have been accustomed to using natural heat sources and natural ventilation to dry materials, which is completely restricted by natural conditions and the production capacity is low. With the development of production, they are gradually replaced by artificial controllable heat sources and mechanical ventilation and dehumidification methods. Drying equipment is also called dryer and dryer. The equipment used for drying operation, the moisture in the material (generally refers to water or other volatile liquid components) is vaporized and escaped by heating to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. For example, the drying of wood before making wooden molds and wooden utensils...

Problems solved by technology

[0004] Prior art, such as the patent document of Chinese invention authorization, the authorized announcement number CN 104848666 B, the invention discloses a dryer based on electromagnetic heating, the invention uses electromagnetic heating elements to heat the surrounding air, and then the hot air is blown by a high-pressure fan Pumped into the inner box, the wet material is heated and dried in the inner box, and the humid low-temperature air is pumped to the electromagnetic heating element for circular heating, which realizes heat recovery and reuse, reduces heat loss, and saves resources. However, the inner box in this invention Long-term contact with hot and humid air will cause oxidation and corrosion of the inner box, and then aging and deformation will affect the use, and even need to replace parts
