The rapid moisture removal drying device of CABLE MATERIALS
Technical field
The present invention relates to the rapid moisture removal drying device in a kind of cable production, specifically a kind of cable rubber materials that suction is made moist carries out the device of rapid moisture removal drying.
Background technology
When carrying out cable plastic extrusion, if the CABLE MATERIALS suction is made moist, can cause the apparent bad and hydraulic performance decline of cable.And CABLE MATERIALS wherein can contain some polar material compositions usually because of performance need; this constituents so that CABLE MATERIALS easily suction make moist; especially every multiple time of summer high temperature rainwater of south China area; air humidity is high; cause the CABLE MATERIALS suction to make moist serious, cable manufacturer can produce after CABLE MATERIALS is carried out removal moisture drying.Existing drying equipment is directly will to be blown into by fan inleting pipe without the air of any processing, and then the air that is blown into discharges from the napex steam vent of hopper via being heated CABLE MATERIALS, with this CABLE MATERIALS is carried out drying dehumidification, and there is following deficiency in it:
1, be blown into air without dehumidifying, when air humidity hour, generally need process at least the moisture that could remove more than 3 hours in the material, drying time is long, power consumption is large, production efficiency is low.
2, be blown into without the air that dehumidifies, when air themperature is larger, material do not had the effect of dehumidifying at all, make on the contrary the material water sucting degree more serious, cause dry illusion, cause to produce and interrupt.
Therefore, should provide a kind of new technical scheme to address the above problem.
Summary of the invention
The objective of the invention is: for above deficiency, provide the rapid moisture removal drying device of a kind of easy to use, saves energy, CABLE MATERIALS that production efficiency is high.
For achieving the above object, the technical solution used in the present invention is: the rapid moisture removal drying device of CABLE MATERIALS, comprise hopper, air dehumidifier and air extractor, described hopper comprises casing, be located at the charge door of casing top and the feed opening of being located at the casing below, described charge door is provided with the charge door seal cover, described feed opening is provided with the feed opening seal cover, described box house is provided with electrical heating wire, described air dehumidifier comprises housing, be located at filter and the humidity detecting alarm of enclosure interior, described air dehumidifier is fixedly connected with hopper, described air extractor comprises vavuum pump and connecting hose, and described air extractor is fixedly connected with hopper by connecting hose.
The present invention at first adds material in the material bin in use, locks afterwards charge door seal cover and feed opening seal cover, starts whole device and carries out removal moisture drying.During work, air dehumidifier can filtering enter the airborne moisture in the hopper, makes the air humidity that enters in the hopper less than 30%, and exceeding top limit of humidity humidity detecting alarm will report to the police, carries out dehumidifying work after changing the filter in the dehumidifier at this moment again; During work, the vavuum pump of bleeding is constantly extracted the heated gas in the hopper out, and the air pressure in the hopper is descended, in the situation that air pressure descends, the boiling point of water can reduce, and the moisture in the CABLE MATERIALS easily becomes steam and is drawn out of; Air dewetting and vacuum suction act on simultaneously, can make the serious CABLE MATERIALS of suction can finish dehumidifying in very short time, reach dry effect, can make the general CABLE MATERIALS that absorbs water carry out online drying and use continuously.
Advantage of the present invention is: device is simplified easily capable, easy to use, saves energy, and production efficiency improves.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, hopper, 2, air dehumidifier, 3, air extractor, 4, casing, 5, charge door, 6, feed opening, 7, the charge door seal cover, 8, the feed opening seal cover, 9, electrical heating wire, 10, housing, 11, filter, 12, the humidity detecting alarm, 13, vavuum pump 14, connecting hose.
The specific embodiment
As shown in Figure 1, the rapid moisture removal drying device of CABLE MATERIALS of the present invention, comprise hopper 1, air dehumidifier 2 and air extractor 3, hopper 1 comprises casing 4, the feed opening 6 of being located at the charge door 5 of casing 4 tops and being located at casing 4 belows, charge door 5 is provided with charge door seal cover 7, feed opening 6 is provided with feed opening seal cover 8, casing 4 inside are provided with electrical heating wire 9, air dehumidifier 2 comprises housing 10, be located at filter 11 and the humidity detecting alarm 12 of housing 10 inside, air dehumidifier 2 is fixedly connected with hopper 1, air extractor 3 comprises vavuum pump with 13 and connecting hose 14, and air extractor 3 is fixedly connected with hopper 1 by connecting hose 14.
The present invention at first adds material in the material bin 1 in use, locks afterwards charge door seal cover 7 and feed opening seal cover 8, starts whole device and carries out removal moisture drying.During work, air dehumidifier 2 meeting filterings enter the airborne moisture in the hopper 1, make the air humidity that enters in the hopper 1 less than 30%, exceeding top limit of humidity humidity detecting alarm 12 will report to the police, carry out dehumidifying work after changing the filter 11 in the dehumidifier at this moment again; During work, the vavuum pump 13 of bleeding is constantly extracted the heated gas in the hopper 1 out, and the air pressure in the hopper 1 is descended, in the situation that air pressure descends, the boiling point of water can reduce, and the moisture in the CABLE MATERIALS easily becomes steam and is drawn out of; Air dewetting and vacuum suction act on simultaneously, can make the serious CABLE MATERIALS of suction can finish dehumidifying in very short time, reach dry effect, can make the general CABLE MATERIALS that absorbs water carry out online drying and use continuously.
