Abstract
The invention relates to fiber drying devices, in particular to a sea-island fiber drying device which comprises a drying tower for placing fibers to be dried, wherein the drying tower is connected with a drying heater, and the drying heater is connected with a compression air dehumidifier for supplying dried air. The sea-island fiber drying device performs once dehumidification and compression on the air through the compressed air, then the air is dried through the drying heater and then enters the drying tower, the dried air proper in temperature is supplied to the drying tower, after four hours of drying, the moisture content of a section is lower than 25*10-6, the moisture content of the dried section is low, and accordingly, normal production of sea-island fiber is ensured.
Description
Technical field
The present invention relates to a kind of fiber drying equipment, especially a kind of sea-island fibre drying device.
Background technology
At present, sea-island fibre is progressively accepted by weaving and non-woven enterprise, synthetic leather enterprise with its good performance, and the products such as the imitative musk deer skin suede that it is made, clean-cloth are subject to domestic and international consumer's favor.Because oil goes up in recent years, chemical chemical fibre raw material cost increases, and the profit margin of traditional chemical fiber is diminished, and sea-island fibre has the characteristics of high added value, high profit because of it, impels domestic large quantities of enterprise then the production and processing field of trend of purchasing sea-island fibre.
In the process of sea-island fibre, owing to adopting the traditional drying device, in actual mechanical process, not only easily produce dried section moisture content higher, sea-island fibre is the polyesters product, its heat endurance is relatively poor, moisture is that the form with hydrogen is present between the large molecule, and the chip drying effect is bad, causes the polyester macromolecule hydrolysis to make the ester linkage breaking aggravation, all cause the melt elasticity factor to increase, be unfavorable for spinning; Perhaps cause affecting the bad phenomenon such as intrinsic viscosity because section excessively of a specified duration, bake out temperature of the time of staying in drier is too high.
Summary of the invention
The invention provides a kind of chip drying better effects if, be beneficial to a kind of sea-island fibre drying unit of spinning.
To achieve these goals, the present invention adopts following technical scheme:
This drying unit comprises that one places the drying tower of fiber to be dried, and described drying tower connects a drying heater, and drying heater connection one provides the compressed air dehumidifier of dry air.
Preferably, be provided with the flow decompressor between described drying heater and the compressed air dehumidifier.
Preferably, described drying tower is vertically placed.
Preferably, fiber entry is located at the drying tower top, and the drying tower bottom is located in outlet.
Preferably, described drying heater is connected on the drying tower sidewall.
Preferably, be provided with a surge tank below the described drying tower.
Preferably, described compressed air dehumidifier is a bipolar aerial cooler.
Preferably, comprise in the described drying heater that one arranges the Programmable Logic Controller of drying heater power.
Preferably, described drying tower exit is inverted cone-shaped structure.
Preferably, described surge tank is inverted cone-shaped structure.
Owing to having adopted said structure, a kind of sea-island fibre drying unit of the present invention by the compressed air dehumidifier air is once dehumidified first and compress after again through entering drying tower after the redrying of drying heater, the dry air of suitable temperature is provided for drying tower, can makes section moisture content＜25 * 10 in dry 4 hours
-6, the moisture content of dry rear section is lower, thereby has guaranteed the normal production of sea-island fibre.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Among the figure: drying tower 1, drying heater 2, compressed air dehumidifier 3, flow decompressor 4, surge tank 5.
The specific embodiment
As shown in Figure 1, a kind of sea-island fibre drying unit of the present embodiment comprises that one places the drying tower 1 of fiber to be dried, and described drying tower 1 connects a drying heater 2, and drying heater 2 connections one provide the compressed air dehumidifier 3 of dry air.
Because compressed air dehumidifier 3 provides compressed air among this city embodiment; gas pressure is larger; in order to reduce the impact to drying heater; the normal operation of protection drying heater; in the present embodiment; between described drying heater 2 and compressed air dehumidifier 3, be provided with flow decompressor 4, such as pressure-reducing valve etc.
In order to be beneficial to the discrepancy of sea-island fibre section, in the present embodiment, described drying tower 1 is vertically placed, and fiber entry is located at drying tower 1 top, and drying tower 1 bottom is located in outlet.
Because drying tower 1 is vertically to place, so that drying is carried out in the section of sea-island fibre wherein, in the present embodiment, described drying heater 2 is connected on drying tower 1 sidewall for fully.
In order to be beneficial to the steady output of dried sea-island fibre section, in the present embodiment, described drying tower 1 below is provided with a surge tank 5.
Particularly, in the present embodiment, described compressed air dehumidifier is a bipolar aerial cooler, at first with the pressure-air cooling by wherein to dew point-140 ℃, remove moisture wherein, then be input to drying heater 2.
Because the heating power of drying heater is too high, disadvantageous changes can occur in the performance of section; Cross the low drying effect that affects, in order reasonably to control the operating temperature of drying heater, comprise in the drying heater 1 described in the present embodiment that one arranges the Programmable Logic Controller of drying heater power.
In addition, the drying tower exit described in the present embodiment is inverted cone-shaped structure; Described surge tank is inverted cone-shaped structure.
The above only is the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
