The described air-heater that send comprises motor, casing and impeller, impeller is located in casing, impeller comprises plectane and the Circular Plate of parallel and coaxial setting, between plectane and Circular Plate, edge is circumferentially evenly provided with a circle blade, the center of plectane is provided with the mount pad being connected with electric machine main shaft, casing is provided with air intake tube coupling and air-out tube coupling, the center line of air intake tube coupling overlaps with the center line of impeller, the center line of air-out tube coupling is vertical with the center line of impeller, air intake tube coupling is connected with Circular Plate inside edge, and the import of air-out tube coupling is towards blade.
In described casing, level is provided with the carrying roller that a row moves for holding up goods, and carrying roller is positioned at tuyere below.
Described a set of baking oven is combined by least two unit baking ovens, each unit baking oven length is 3 meters, 4 meters or 5 meters, each baking oven top, unit is all connected with a blast pipe, the outlet of all blast pipes is all connected on an exhaust supervisor, exhaust supervisor is provided with exhaust blower, the front end face top of previous element baking oven is provided with charging aperture, the rear end face top of last unit baking oven is provided with discharging opening, and the top of charging aperture is equipped with the top of discharging opening the gather qi together cover being connected with contiguous blast pipe.
Adopt technique scheme, the goods difference of the utility model because producing, the technological process of production line is not identical yet, the length of the baking oven quantity configuring in production line and single cover baking oven is also different, as rolling process PVC artificial leather, PVC floor, painting is scraped the production lines such as method latex foam and is all adopted the long single cover baking oven of a 30m～50m, and cladding process PU/PVC synthetic leather, cladding process PVC floor, cladding process split leather production line adopts single cover baking oven that many precision coating machines mate a plurality of different lengths to form, be called for short " several bakings of several paintings " production line, cladding process PU/PVC synthetic leather or the PVC floor production line forming as the single cover baking oven by four precision coating machine coupling quadruplet different lengths is called for short " four are coated with four dries " production line, list by three precision coating machine coupling three cover different lengths overlaps cladding process split leather production line abbreviation " three-coat three-baking " production line that baking oven forms.Single cover baking oven is comprised of the unit baking oven of different quantity.
Single cover baking oven length can be set as 8 m, 12m, 16m, 20m or 24m ... etc.; Single cover baking oven of different length is comprised of a plurality of unit baking oven again.
The framework of casing of the present utility model adopts section steel manufacture, fills compressing alumina silicate fibre piece in warming plate, not yielding, high insulating effect; Heat insulation effect is better, more energy efficient.The regulation and control that " volume adjusting apparatus " (disclosed technology of utility model that the patent No. is ZL200920258077.3), deflector and tens of " tuyere " (patent No. is the disclosed technology of the utility model of ZL 200920091398.9) are realized the horizontal hot blast of baking oven is housed on the horizontal blast pipe of each unit baking oven, makes baking oven transverse temperature uniformity.The heat exchanger that each unit baking oven mates, send air-heater, air channel, air compensation device and air draft pipeline to form hot-air system, make to form micro-negative pressure in baking oven, with protection from fumes, leak.The temperature of each single cover baking oven all can be set arbitrarily and temperature-constant operation by subregion.All baking ovens adopt loose mail shipping, Assembling; Be conducive to transportation and maintenance, especially for products for export, be conducive to container shipping.Unit baking oven has formed modular designs sizing, is conducive to the promotion and implementation of standardization, seriation, generalization three chemical industry works, and has improved operating efficiency, has reduced manufacturing cost.
Single cover baking oven length is relevant with line speed; The linear velocity of goods in baking oven requires higher, and single cover baking oven length is longer, and baking oven breadth width is wider, and the goods breadth of producing is wider; More wide being more difficult to of baking oven breadth manufactures, and requires whole technology content higher.Be specially: line speed is directly proportional to baking oven length: products thickness and line speed are inversely proportional to; Oven temperature is directly proportional to line speed: the uniformity of goods transverse gage error and baking oven transverse temperature is inversely proportional to.
160 ℃～180 ℃ of PU/PVC artificial leathers, PVC floor, the theoretic blowing temperature of PVC slipmat goods, and restricted by the regular hour, foamed time as theoretical in the artificial leather of products thickness 1mm is one minute (time of staying in baking oven), if 20 meters of baking oven length, line speed is in 20m/min left and right; 30 meters of blowing oven length, line speed is in about 30m/min, (line speed and industrial chemicals select with fill a prescription relevant).More long production efficiency is higher for blowing oven, and production line overall technology content requirement is also higher, manufactures also more difficult.
Heat exchanger of the present utility model is to adopt roll extrusion technology to manufacture the radiating fin of heat exchanger, is about to aluminium pipe sleeve and on seamless steel pipe, relies on mould to carry out roll extrusion, and aluminum pipe is rolled into interval fin uniformly and equidistantly.Aluminum pipe is closely as one with seamless steel pipe surface in rolling process, can eliminate like this gap of fin and radiating tube, has improved heat-conducting effect.Heat exchanger is also needed to carry out pressure test: heat exchanger is placed on pressure test bench, heat exchanger is carried out to inspection for leakage, heat exchanger continues 10min under 0.5MPa pressure, must not have Seepage (deep fat on-line operation pressure≤0.3MPa).
Heat in heat exchanger relies on and send air-heater to be sent into air channel, through sending " volume adjusting apparatus ", " deflector " and " tuyere " that hot blast is sent into baking oven.
Send air-heater to adopt low blast Wind Volume blower fan, motor adopts variable-frequency motor coupling Frequency Converter Control, has replaced traditional axial flow blower and common centrifugal fan.The air-heater that send in the utility model has all overcome the disadvantage existing with fan, and it adopts centrifugal blower pattern, and Multi-vane type impeller lengthens shaft type motor, and the air quantity producing is large, and the little noise of blast is also little.
On each unit box, all connect a blast pipe, it is upper that the outlet of the blast pipe of all blast pipes is all connected to an exhaust supervisor, and exhaust supervisor is provided with exhaust blower, like this blower fan on existing each unit baking oven blast pipe is removed, and has reduced cost.And gather qi together cover is set, and to absorb by charging aperture and discharging opening, be discharged to the waste gas outside casing, so just can avoid waste gas to the pollution in workshop, improve people's physical and mental health.Exhaust blower employing variable-frequency motor on exhaust supervisor is controlled, and gas flow rate in pipeline is accelerated, and makes the micro-negative pressure of formation in casing, exhaust is unimpeded, each blast pipe overlapping on baking oven need not be joined air exhauster again, and it is unimpeded that the exhaust blower that only needs exhaust to be responsible for can be realized exhaust, saves the energy.
