Electromagnetic drying heating equipment

Abstract

The invention discloses electromagnetic drying heating equipment, which comprises a frame. Both ends of the frame are respectively provided with left and right gears. The left and right gears are sleeved with transmission belts which carry out circulating transmission. Heaters which are arrayed in lines are arranged on the frame. The heater are all positioned above the transmission belts. Each heater comprises a bottom plate and an upper cover covered on the bottom plate. An air duct is formed between the upper cover and the bottom plate in a surrounding mode. The bottom plate is fixedly provided with glass ceramics. A plurality of coil panels which are connected in series or in parallel are arrayed on the glass ceramics. A magnetic block is respectively adhered on the upper surface of each coil panel. The electromagnetic drying heating equipment has the advantages of high working efficiency, good drying effect, long service life and the like.

Description

Technical field: [0001] The invention mainly relates to an electromagnetic drying and heating device. Background technique: [0002] Electromagnetic heating drying equipment is mainly used to recoat and dry the weld seams of various tanks. The welded seam on the tank body after repainting is not easy to be corroded, which is conducive to the preservation of the items in the can for a longer period of time. The traditional drying methods are gas drying line and electric heating drying line, but these two drying lines have certain defects: the gas drying line mainly burns liquefied gas, and the length of the drying line is generally 6 meters, 9 meters, 13 meters, 18 meters, can meet 120 cans / min, 150 cans / min, 160 cans / min, 180 cans / min, 200 cans / min, etc. The main disadvantages are high economic cost and easy aging of the drying line. Low thermal efficiency, combustion residue, waste discharge, poor drying effect, potential safety hazards of open flames, liquefaction tanks ...

Problems solved by technology

The traditional drying methods are gas drying line and electric heating drying line, but these two drying lines have certain defects: the gas drying line mainly burns liquefied gas, and the length of the drying line is generally 6 meters, 9 meters, 13 meters, 18 meters, can meet 120 cans / min, 150 cans / min, 160 cans / min, 180 cans / min, 200 cans / min, etc. The main disadvantages are high economic cost and easy aging of the drying line. Low thermal efficiency, combustion residue, waste discharge, poor drying effect, open flame safety hazards, liquefaction tanks need to be preheated in winter and many other shortcomings; the electric heating drying line is mainly heated by resistance wire, and the length of the drying line is the same as that of gas drying. The main disadvantages are high economic cost, easy aging of resistance wire, low thermal efficiency, poor drying effect, and large external heat radiation.
