сушки линия туннеля

Introduction: Line drying tunnel applicable to all types of objects through the hot air to dry after wet work. Line body with stainless steel mesh or PVC belt running straight up and down cycle of closed-end way. Electric heating temperature control air circulation, drying power operation for the object. Use of a wide range of drying tunnel line, drying line for the metal, electroplating, chemical, packaging, electronics, leather, painting, screen printing, plastics, food and other industries. Drying tunnel line features: drying tunnel line is warming rapidly, the product even heat, drying line can be sustainable with the continuous production of dried plant product line, drying line may also need to adjust the baking temperature by the production, transmission speed and time, can greatly increase production efficiency, using simple and convenient. Drying tunnel line of the transmission mode: chain mesh, mesh belt, string rod, Teflon-type, belt type. Heating method: heating pipe + transport wind, quartz tube heating, diesel burner heating, far infrared radiation heating. Technical parameters: (1) Dimensions: length 20 meters, outside the width of 0.8 m, 0.65 m in width, 1.3 meters high, 5 meters long feed section, drying section 12 meters long, a material part of a long 3 m; rack with 40 × 80 mm welded square pass, the line beam with 2 mm thick body made cold plate, spray (non-P injection) corrosion-resistant, easy to clean. (2) drying parts: 6 section of the furnace liner, furnace ceiling height 0.28 meters, drying area 12 meters in length, liner made by 1.2mm galvanized plate, 60 mm high-temperature insulation to prevent rust oxidation; bottom with insulation. (3) electrical parts: power supply 380V, 30A, three-phase five-wire system, power 40KW, using 2P benefit Taiwan's Love Frequency inverter 1.5KW, transmission speed of 0.5-8 m / min Adjustable; by Japan RKC Smart thermostat, the temperature from room temperature to 250 °C adjustable, self-tuning PID function, automatic constant temperature, over-temperature power failure, over temperature settings, dual thermostat control, leakage protection function, the internal temperature difference of ± 3 degrees; other Control circuit devices are controlled by Mitsubishi Electric; each piece of the furnace chamber air motor with 2 sets of transport, for a total of 12 units with 10-inch wheels shipped air damper, each loaded nine stainless steel heating pipes, each uniformly distributed in the furnace chamber 500KW inside, each furnace temperature can be controlled separately, each piece easy to set different temperatures; (4) Transmission parts: the use of imported stainless steel mesh chain belt, head tail with active-passive conditioning drum, the middle has no power-dragging roller bearing to prevent the belt run edge.
