Abstract
The utility model discloses a tail-gas-preheated drum drying device for chemical fiber production. The device comprises a drum drier, wherein a preheating tank is arranged above the drum drier; a material outlet tube of the preheating tank is connected to a material inlet of the drum drier; the preheating tank is provided with a clamping sleeve; a gas inlet is formed below the clamping sleeve, and is connected with a tail gas outlet of the drum drier; and a gas outlet is formed above the clamping sleeve. By the tail-gas-preheated drum drying device for the chemical fiber production, bottles are preheated by tail gas generated by the drum drier, so that drying time is shortened, daily yield is increased, the tail gas is recycled, and energy conservation and emission reduction are realized; and due to the preheating, the bottles can be fully dried, so that the product quality of chemical fiber is improved.
Description
Technical field
The utility model relates to the chemical fibre production technical field, be specifically related to use in a kind of production of chemical fibres, utilize tail gas to carry out the drum dried device of preheating.
Background technology
Chemical fibre has very important effect at life, industrial circle, utilizes the returnable bottle sheet to spin and not only can solve polyester to the pollution of environment, and can realize the recycling of resource, thereby reduce energy resource consumption, alleviates chemical fibre industry to the dependence of crude oil.The more important thing is that utilize the bottle sheet that reclaims to weave terylene short fiber, cost is very low, product price is with the obvious advantage.
In process of production, the drying of bottle sheet is the operation of one key.The bottle sheet drum dried that adopts at present is raw material directly to be sent into rotary drum carry out drying, the material temperature that enters like this rotary drum is exactly room temperature, be about 30 ℃ summer, just only has 0～10 ℃ winter, bottle sheet in the rotary drum to be heated to more than 150 ℃, reach its dry purpose through vacuumizing discharge moisture.A dry drum bottle sheet needs 12 hours, namely consuming timely requires great effort again, takes resource, and to spin output also be bottleneck to improving feed back; And because drying is insufficient, can cause the Quality Down of fiber product.
The utility model content
Technical problem to be solved in the utility model provides the chemical fibre production pre-heated drum dried device of tail gas, and it can utilize tail gas that the bottle sheet is carried out preheating, then carries out drying, thereby eliminates defective in the above-mentioned background technology.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The chemical fibre production pre-heated drum dried device of tail gas, comprise rotary drum drier, it is characterized in that, the top of described rotary drum drier is provided with preheating can, the material outlet pipe of described preheating can is connected to the charging aperture of described rotary drum drier, and described preheating can has chuck, and the below of described chuck is provided with air inlet, described air inlet connects the tail gas outlet of described rotary drum drier, and the top of described chuck is provided with the gas outlet.
As a kind of improvement, be provided with push-pull valve on the material outlet pipe of described preheating can, in order to control the discharging break-make of material.
As a kind of improvement, the volume of described preheating can is identical with the rotary drum volume of described rotary drum drier.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
The drum dried device that the utility model provides, above rotary drum drier, be provided with preheating can, the bottle sheet is carried out preheating, and preheating can has chuck, the air inlet of chuck below connects the tail gas outlet of rotary drum drier, based on this structure, the tail gas that the utility model can utilize rotary drum drier self to produce carries out preheating to the bottle sheet, makes a bottle sheet temperature that enters rotary drum 20～30 degree that raise, and has reduced the drum dried time, make reduce to 10.5 hours by original 12 hours the drying time of transferring shares, improve the daily output, solved the bottleneck problem of the spinning threadling daily output, recycled tail gas, energy-saving and emission-reduction have been realized, for low-carbon economy has been made contribution; And owing to carried out preheating, the bottle sheet can be carried out sufficient drying, improved the product quality of chemical fibre.
The utility model is provided with push-pull valve at the material outlet pipe of preheating can, and is in order to control the discharging break-make of material, more convenient to operate.
Description of drawings
Accompanying drawing is the utility model structural representation;
Among the figure: 1. rotary drum drier, 11. charging apertures, the outlet of 12. tail gas; 2. preheating can, 21. material outlet pipes, 22. chucks, 23. air inlets, 24. gas outlets, 25. push-pull valves.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in drawings, the chemical fibre production pre-heated drum dried device of tail gas, comprise rotary drum drier 1, it is characterized in that the top of described rotary drum drier 1 is provided with preheating can 2, the material outlet pipe 21 of described preheating can 2 is connected to the charging aperture 11 of described rotary drum drier 1, described preheating can 2 has chuck 22, the below of described chuck 22 is provided with air inlet 23, and described air inlet 23 connects the tail gas outlet 12 of described rotary drum drier 1, and the top of described chuck 22 is provided with gas outlet 24.
In the present embodiment, be provided with push-pull valve 25 on the material outlet pipe 21 of described preheating can 2, in order to control the discharging break-make of material.
In the present embodiment, the volume of described preheating can 2 is identical with the rotary drum volume of described rotary drum drier 1, and this structure is beneficial to effectively to be controlled bottle sheet inlet amount.
Operation principle of the present utility model is as follows:
When charging, first the bottle sheet is sent in the preheating can 2, the chuck 22 of preheating can 2 exports the higher tail gas of 12 recovered temperatures from the tail gas of rotary drum drier 1, the tail gas that reclaims is through in the process of chuck 22, heat can be passed to the bottle sheet in the preheating can 2, make a bottle sheet temperature that enters rotary drum drier 1 20～30 degree that raise.
The utility model is not limited to the above-mentioned specific embodiment, and all are based on technical conceive of the present utility model, and the structural improvement of having done all falls among the protection domain of the present utility model.
