Abstract
The utility model relates to components of production equipment for plastic monofilaments such as plastic flat filaments and round filaments, in particular to a circulating hot-air oven. The circulating hot-air oven is provided with two fans, two airflow regulators and two lower channels, heaters are respectively arranged at air outlets of the fans, the two fans are respectively arranged on the left and right sides of an inner case, a screen plate is arranged above an air suction hole, and the airflow regulators are arranged in the lower channels. The circulating hot-air oven utilizes dual fans to work simultaneously, two streams of circulating air are generated in an upper channel, and each stream of circulating air enters each lower channel via the screen plate after flowing through half section of the upper channel, thereby minimizing heat loss of circulating air in the upper channel, keeping temperature in the upper channel constant +-1 degrees and then guaranteeing thermal shrinkage among filaments to reach +-0.2%.
Description
Technical field
The utility model relates to plastic monofilament production equipment component technology fields such as a kind of plastic flat fiber, circle silk, the circulating hot-air oven that especially a kind of monofilament that stretches or finalize the design is used.
Background technology
Produce both at home and abroad at present, the production plastic flat fiber of selling and using, used circulating hot-air oven in the equipment of plastic monofilaments such as circle silk, general structure is: by casing and blower fan, blower fan is fixed on the casing, the spiral case of blower fan is arranged in the casing, be provided with upper runner and lower flow channel in the casing, upper runner is the work runner, monofilament passes upper runner, owing in the upper runner hot blast is arranged, monofilament is stretched in upper runner or finalize the design, this structure, since the wind that blower fan blows out, the air quantity maldistribution, and wind-force is bigger all around, it is slower that wind-force less cold wind in center will absorb the heat of heater surfaces, the temperature of the hot blast after the heater heating can not be balanced everywhere, and upper runner is longer, and hot blast passes upper runner must have thermal loss, therefore the temperature in the upper runner is unbalanced, therefore just can not guarantee that also the monofilament shrinkage factor is consistent.
The utility model content
The technical problems to be solved in the utility model is: for overcoming the deficiency of existing circulating hot-air oven, provide the balanced circulating hot-air oven of temperature in a kind of upper runner everywhere.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of circulating hot-air oven, has long and narrow outer case, internal box and blower fan, fill insulant material between outer case and internal box, blower fan and internal box, outer case is fixedly connected, blower fan has spiral case, spiral case has inlet scoop and air outlet, spiral case is arranged in the internal box, also be provided with heater in the internal box, web plate, upper runner, lower flow channel, blast regulator and two air deflectors, air deflector and lower flow channel are wrapped with insulation material, two air deflectors are separately positioned on the internal box two ends, two air deflector outlet tops are upper runner, the outlet of air deflector communicates with upper runner, heater is arranged on the air outlet place of blower fan, blower fan, blast regulator and lower flow channel respectively have two, and two blower fans are separately positioned on the left and right sides of internal box, web plate is arranged on the top, inlet scoop, and blast regulator is arranged in the lower flow channel.
The beneficial effects of the utility model are, circulating hot-air oven of the present utility model, adopt the hot blast output type, so temperature equalization of the hot blast in the upper runner, and, circulating hot-air oven of the present utility model adopts two blower fans to work simultaneously, have two strands of circulated airs in the upper runner, per share circulated air is only just entered in the lower flow channel by web plate through more than half sections upper runners, therefore the thermal loss of circulated air in upper runner is extremely low, can guarantee that temperature in the upper runner remains constant temperature ± 1 ℃, thereby can guarantee that percent thermal shrinkage reaches between silk ± 0.2%.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. outer case, 2. internal box, 3. blower fan, 4. insulation material, 5. heater, 6. web plate, 7. upper runner, 8. lower flow channel, 9. blast regulator, 10. air deflector, 11. spiral cases, 12. inlet scoops, 13. air outlets.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Of the present utility model circulating hot-air oven as shown in Figure 1, has long and narrow outer case 1, internal box 2 and blower fan 3,2 fill insulant materials 4 of outer case 1 and internal box, blower fan 3 and internal box 2, outer case 1 is fixedly connected, blower fan 3 has spiral case 11, spiral case 11 has inlet scoop 12 and air outlet 13, spiral case 11 is arranged in the internal box 2, also be provided with heater 5 in the internal box 2, web plate 6, upper runner 7, lower flow channel 8, blast regulator 9 and two air deflectors 10, air deflector 10 and lower flow channel 8 are wrapped with insulation material 4, two air deflectors 10 are separately positioned on internal box 2 two ends, two air deflector 10 outlet tops are upper runner 7, the outlet of air deflector 10 communicates with upper runner 7, heater 5 is arranged on air outlet 13 places of blower fan 3, blower fan 3, blast regulator 9 and lower flow channel 8 respectively have two, and two blower fans 3 are separately positioned on the left and right sides of internal box 2, web plate 6 is arranged on 12 tops, inlet scoop, and blast regulator 9 is arranged in the lower flow channel 8.
The back air outlet 13 by spiral case 11 of heater 5 heating is blown into and enters upper runner 7 in the air deflector 10, through upper runner 7 by web plate 6 lower flow channel 8, enter the inlet scoop 12 of spiral case 11 again through lower flow channel 8, form circulation, the amount that sucks the circulated air of blower fan 3 is regulated control by blast regulator 9, because circulating hot-air oven adopts the hot blast output type, adopt two blower fans to work simultaneously, have two strands of circulated airs in the upper runner 7, per share circulated air only just enters lower flow channel 8 by web plate 6 through more than half sections upper runners 7, therefore the thermal loss of circulated air in upper runner 7 is extremely low, can guarantee that temperature equilibrium everywhere in the upper runner 7 remains constant temperature ± 1 ℃, thereby can guarantee that percent thermal shrinkage reaches between silk ± 0.2%.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.
