Description

Metal does not have pipe hot-air furnace pressing equipment

Technical field

The present invention relates to a kind of flatiron machinery, especially a kind of metal does not have pipe hot-air furnace pressing equipment.

Background technology

Domestic existing pressing equipment all feeds drying cylinder inside with steam, is converted to the heat on surface, coverlet etc. is adhered to dryer surface roll, and it is dry that cloth is plated.Such drying machinery has following shortcoming: 1. investment is big, is example with half ton of boiler, about 40,000 yuan of every purchase commodity, press in addition, gross investment is wanted about 7～80,000 yuan, and boiler year maintenance cost big, the kettleman must carry out special training.2. use the conversion of vapour seasoning heat unstable.When steam pressure was low, surface temperature of drier was not high, needed the boiling hot whole ability of secondary dry qualified.3. floor space is big, because it adopts the bilateral turnover of dried wet cloth, therefore, the whole machine installation area is wanted 12 square metres at least, if the twin-tub of import or three cylinder cloth press, floor space is just bigger.4. burnup is big, oven dry cost height.Advance in the heat conversion because use steam to feed oven dry, cooled hot soup does not reclaim, the waste waste heat.

Summary of the invention

Technical problem to be solved by this invention provides a kind of metal does not have pipe hot-air furnace pressing equipment, to overcome the deficiencies in the prior art part.

The technical solution adopted for the present invention to solve the technical problems is: adopt square all-metal not have pipe hot-air furnace as heat power supply device, be equipped with the new hot air circulation pipe-line system of scalding whole structure and Controllable Temperature.Now that each partial structure form division is as follows: 1. square all-metal does not have pipe hot-air furnace: wherein include body of heater, negative pressure smoke exhaust fan.2. scald whole structure partly: by the medium current limiter, fixedly iron drying cylinder, axle, steam wet-emitting blower, hydrofuge suction pipe, steam cover, frame, frame fixedly rod, bearing, buncher, gearbox, driving-chain, cloth input shaft, flat belt, cloth pressure zone, cloth pressure zone power transmission shaft, woven belt, woven belt power transmission shaft, play other parts such as cloth device, a cloth device axle, pressure zone tensioning shaft, dried, wet cloth storagetank, electric control panel and form.The centre be cylinder, two ends be the medium current limiter of cone by fixing iron, be welded in the drying cylinder, both center lines coincide.The outside of drying cylinder is equipped with semicircle steam cover, and an end of hydrofuge suction pipe passes frame and stretches into space under the steam cover, and the air inlet of the other end and wet-emitting blower joins, and the air outlet of wet-emitting blower is connected to the steam dehumidification tube.The two ends of drying cylinder are connected to tubular shafts, respectively as drying cylinder into and out of the air port.Axle is enclosed within respectively in the bearing, plays to support and rotary action.Bearing is fixed on the frame by bearing block.Two frames then by upper and lower two fixedly rod live with fixed by nut.The lateral surface of frame gets up with the sheet metal inclusion.Buncher, gearbox all are fixed on and lean on bottom position in the frame, and electric control panel is positioned on the upper right side of frame front end face.The cloth input shaft, cloth pressure zone power transmission shaft, woven belt power transmission shaft, a cloth device axle and tensioning shaft are contained in the outside of oven dry respectively, and their two ends are fixed on two frames by bearing, bearing block.Flat belt, woven belt are contained on cloth input shaft, the woven belt power transmission shaft, and the cloth pressure zone then is stretched on the cloth pressure zone power transmission shaft by tensioning shaft, and the top of cloth presser tape spool is provided with hold-down mechanism.Playing the cloth device has been fixed on the cloth device axle.3. thermal medium circulating pipe system: comprise into and out of airduct, thermal medium driving blower fan, blower fan frame, circulation airduct, circulated air horn mouth, temperature controller, temperature-control senser etc.Above-mentioned pipe-line system and body of heater, drying cylinder and two end axles are promptly formed a closed circuit.The thermal medium driving blower fan sunlight air inlet and the discharge pipe that are positioned on the blower fan frame join, and air outlet is connected with the air inlet of circulation airduct, and the circulation airduct is by circulated air horn mouth and body of heater closure.In order to reach temperature automatically controlled, be equipped with the temperature regulating device that temperature controller and temperature controller sensor etc. are formed at the blast pipe place

The invention has the beneficial effects as follows: 1. carry out the heat conversion owing to use hot blast, make xeothermic medium in machine, be closed state and circulate, progressively heat, and be provided with the thermal medium automatic temp controller, therefore can make heat medium temperature constant relatively, thermal efficiency height, drying property is reliable, burnup is economized.2. adopt to do, wet cloth with the limit into and out of frame mode, machine volume is dwindled, reduce floor space, reduce operating personnel.3. in transmission system, except adopting light and handy worm gear speed changer, and to select buncher be power, therefore, can do, wet degree the speed of regulated at will drying according to cloth.4. it is easy to make that square all-metal does not have pipe hot-air furnace, and materials are economized, and can save gross investment.
