Technical field

The present invention relates to a kind of textile machine, is a necessary servicing unit of whole pulp grinder, the drying unit in the whole pulp grinder of especially a kind of glass fibre.

Background technology

Drying unit in the whole pulp grinder of existing glass fiber, yarn sheet when getting into baking oven be through guide roller by yarn sheet oven interior divide three layers folding and on, the fin through every interlayer carries out the heating that repeats repeatedly to the glass fibre yarn sheet; Its advantage is to occupy little space, and cost is low, and shortcoming is to control temperature of oven accurately; Complex structure, and yarn sheet directly contacts guide roller, and it is excessive to form amount of localized heat easily; Influence the heats of yarn sheet, the inhomogeneous yarn sheet that also makes easily of guide roller tractive force ruptures, and can not satisfy the high technology requirement of yarn sheet; Simultaneously, the single outside factors that receives easily of mode of heating.

Summary of the invention

The object of the present invention is to provide a kind of wind closed circuit that utilizes that the yarn sheet that moves in the baking oven is heated, will realize that not only resource utilization is high, and the high a kind of glass fibre of the efficiency of heating surface is put in order the drying unit in the pulp grinder;

For realizing above-mentioned purpose; The technical scheme that the present invention adopted is: this device comprises frame; Be located at the baking oven on the machine, on baking oven, be provided with baking oven loam cake, handgrip, be provided with heat-insulation layer at the baking oven inwall; It is characterized in that: the left and right two at baking oven is respectively equipped with yarn import, yarn outlet, is respectively equipped with baking oven air inlet, return air inlet at left and right two of baking oven bottom; On the frame below the baking oven bottom, be provided with the combustion chamber; The combustion chamber air inlet of combustion chamber is connected with return air inlet; The hot blast output of combustion chamber is connected with the blower inlet of power by driven by motor through wind conveying pipe, and the output of air blast is connected with the baking oven air inlet through the air blast exhaust duct; In frame, also be furnished with the exhaust blower of power by the exhaust blower driven by motor, the exhaust blower air inlet of exhaust blower is connected with return air inlet, and the exhaust blower exhaust outlet of exhaust blower is uncovered to be stretched out outside the frame;

Drying unit in the whole pulp grinder of described a kind of glass fibre is characterized in that: in the hot blast wind conveying pipe of combustion chamber, be provided with sensor;

Drying unit in the whole pulp grinder of described a kind of glass fibre, it is characterized in that: baking oven is a cuboid.

The present invention's beneficial effect compared with prior art:

Advantage of the present invention is that hot blast circulates in oven interior, and the efficiency of heating surface is high, energy savings, and the yarn sheet uniform drying, temperature automatically controlled, temperature constant, convenient for installation and maintenance.

Fig. 1 is a structure chart of the present invention.

Among the figure:

1. baking oven air inlet, 2. frame, 3. baking oven, 4. baking oven loam cake, 5. handgrip, 6. combustion chamber air inlet; 7. return air inlet, 8. exhaust blower air inlet, 9. exhaust blower exhaust outlet, 10. exhaust blower, 11. exhaust blower motors; 12. the combustion chamber, 15. motors, 16. air blasts, 17. air blast exhaust ducts, 18. heat-insulation layers; 19. sensor, 20. yarn imports, 21. yarn outlets, 22. yarn sheets, 23. wind conveying pipes.

The specific embodiment:

Describe the present invention in detail below in conjunction with accompanying drawing:

As shown in Figure 1, this drying unit comprises frame 2, is located at the baking oven 3 on the frame 2, on baking oven 3, is provided with baking oven loam cake 4, handgrip 5, is provided with heat-insulation layer 18 at baking oven 3 inwalls; Baking oven 3 adopts cuboids, and feasible yarn path is a rectangle, and baking oven 3 is made up of angle steel and cold-rolled steel sheet, and heat-insulation layer 18 adopts high density silicic acid aluminum wools to fill, and high density silicic acid aluminum wool had both guaranteed that the heat-insulating property of baking oven 3 also guaranteed user's security; Be respectively equipped with yarn import 20, yarn outlet 21 at left and right two of baking oven 3, be respectively equipped with baking oven air inlet 1, return air inlet 7 at left and right two of the bottom of baking oven 3; On the frame 2 below baking oven 3 bottoms, be provided with combustion chamber 12, in the hot blast wind conveying pipe 23 of combustion chamber 12, be provided with sensor 19; The combustion chamber air inlet 6 of combustion chamber 12 is connected with return air inlet 7; The hot blast output of combustion chamber 12 is connected by air blast 16 air inlets that motor 15 drives with power through wind conveying pipe 23, and the output of air blast 16 is connected with baking oven air inlet 1 through air blast exhaust duct 17; In frame 2, also be furnished with the exhaust blower 10 that power is driven by exhaust blower motor 11, the exhaust blower air inlet 8 of exhaust blower 10 is connected with return air inlet 7, exhaust blower exhaust outlet 9 uncovered the stretching out outside the frame 2 of exhaust blower 10;

The course of work:

At first open baking oven loam cake 4 with handgrip 5; Yarn sheet 22 is allocated in the yarn path the baking oven 3 from yarn import 20 to yarn outlet 21; Fasten baking oven loam cake 4 after preparing; When temperature reached predetermined temperature in the baking oven 3, under the acting in conjunction of the yarn-feeding roller on the warp sizing machine, carry-over pinch rolls, yarn sheet 22 was by the speed operation of setting;

The air of the 12 li heating in combustion chamber, after air blast 16 air inlet sucking-offs, hot-air gets into baking oven 3 inner chambers by the exhaust outlet of air blast 16 through air blast exhaust duct 17, baking oven air inlet 1, to yarn sheet 22 even heating, dryings; Under the suction of air blast 16; Hot-air after baking oven 3 inner chambers use is by the set return air inlet 7 of baking oven 3; Get into once more that combustion chamber 12 is heated after air blast 16, air blast exhaust duct 17, baking oven air inlet 1 get into baking oven 3 inner chambers again; Thereby realized the circulation heating utilization of hot air source, improved the uniformity of temperature effectively; Because in wind conveying pipe 23 the insides; The temperaturecontrol sensor 19 that is connected with electrical apparatus control system is housed; Can control the temperature of baking oven 3 inner chambers automatically; In case the temperature of baking oven 3 inner chambers exceeds setting value, electric control system starts 11 energisings of exhaust blower motor makes exhaust blower 10 work, and motor 15 dead electricity air blasts 16 are quit work; Because the air inlet 8 of exhaust blower 10 is connected with return air inlet 7, the hot blast in can mandatory sucking-off baking oven 3 after exhaust blower 10 runnings outside the casing through exhaust outlet 19 discharge baking ovens 3, can reduce the temperature of baking oven 3 inner chambers rapidly; When the temperature of baking oven 3 inner chambers is reduced to setting value; Owing to fit over the temperaturecontrol sensor 19 and baking oven 3 intracavity inter-connections of wind conveying pipe 23 the insides; Electrical apparatus control system quits work exhaust blower motor 11 dead electricity exhaust blowers 10; Make motor 15 get electric air blast 16 work simultaneously, recover former operation cycle state;

Described electrical apparatus control system is a prior art, is not described in detail in this.
