The Masterbatch drying device
Technical field
The utility model relates to the Masterbatch drying equipment, particularly relates to a kind of drying device that is used for the dry dispersion step of small lot Masterbatch.
Background technology
In coloured production process; The dry screening process of Masterbatch is a critical process, and main task is after Masterbatch carries out drying, disperses screening evenly; Quantitatively be injected in the screw rod through syringe again, be spun into colored terylene filament through the heating extrusion molten with section.If Masterbatch dry mass and disperse irregular etc. not reach production requirement will cause great influence to coloured production so, have the typical products in mass production aberration under the serious situation and scrap or break end and produce little curled hair, cause to consume increase.
In order to reach this requirement, general look Silk Mill all adopts the interior logical hot-air of Masterbatch bucket regularly to heat, and emits master batch from discharging opening then, carries out manual work again and disperses the use of screening back.This method drawback: 1, be prone to cause in the bucket up and down the Masterbatch uneven drying that is heated even, moisture content is unstable.2, non-uniform temperature up and down causes the Masterbatch caking easily.3, drying back Masterbatch will carry out manual work grinding screening; Increase employee's workload greatly, therefore can cause the not high employee's abuse of indivedual quality, reduce grinding screening process without authorization; Masterbatch measures incorrect phenomenon when causing spinning, produces influences such as shade deviation.
Summary of the invention
The utility model has overcome the deficiency that exists in the above-mentioned prior art; A kind of Masterbatch uniform drying that makes is provided; Eliminated the caking phenomenon that produces in the Masterbatch dry run; Cancelled artificial grinding screening process, shortened the dry heat time, reduced the drying device of the irregular and Masterbatch injection precision of Masterbatch moisture content the influence of coloured production.
The technical scheme of the utility model is achieved in that
A kind of Masterbatch drying device comprises dry bucket, in dry bucket, vertically is provided with paddle; Dry bucket top is provided with bung, on dry bucket bung, is fixed with motor, and motor connects paddle through decelerator; Dry bucket bottom is connected with the taper screen pack, and taper screen pack lower sides connects the air channel, and heating tube is housed in the air channel; On bung, be provided with exhaust outlet; The screening net is equipped with at the discharging opening place of taper screen pack bottom, and paddle extends in the taper screen pack, and on paddle, is distributed with the multilayer stirring vane.
As preferably, be provided with one deck stirring vane on the paddle in dry bucket, be provided with two-layer stirring vane on the paddle in the taper screen pack.
As preferably; In the taper screen pack; The stirring vane on upper strata connects paddle through connecting rod, and the stirring vane of lower floor directly links to each other with paddle, in the taper screen pack, also is provided with in order to strike off the scraping blade of the Masterbatch that bonds on the screen pack; One end of scraping blade connects the stirring vane on upper strata in the taper screen pack; The other end of scraping blade connects the stirring vane of lower floor in the taper screen pack, and described scraping blade is parallel to taper screen pack sidewall, and the spacing between scraping blade and the taper screen pack sidewall is 2~4mm.Can eliminate the phenomenon of cohering of producing of possibly causing behind the Masterbatch contact thermal air like this at taper screen pack place.
As preferably, the stirring vane in dry bucket is to link to each other with paddle through connecting rod.Can enlarge the stirring scope thus.
Adopted the beneficial effect of the utility model of technique scheme to be:
The characteristics of the utility model are in dry bucket and taper screen pack, paddle to be installed; And descend three groups during the branch of the stirring vane on the paddle is last; Two-layer stirring vane in the cone screen pack can be strengthened Masterbatch and in screen pack, reach lateral flow up and down; And the two-layer stirring vane in the cone screen pack connects scraping blade again, to eliminate the issuable phenomenon of cohering at the screen pack place that possibly cause behind the Masterbatch contact thermal air; Selecting for use of taper screen pack and screening net will have been cut into slices the improper section automatic screening of particle diameter above normal Masterbatch, guarantee quality and Masterbatch screening particle size uniformity that Masterbatch is dry.

The specific embodiment
The specific embodiment of the utility model is following:
Embodiment: a kind of Masterbatch drying device, as shown in Figure 1, comprise dry bucket 1; In dry bucket 1, vertically be provided with paddle 2, dry bucket 1 top is provided with bung 3, on bung 3, is fixed with motor 4; Motor 4 connects paddle 2 through decelerator, and dry bucket 1 bottom is connected with taper screen pack 5, and taper screen pack 5 lower sides connect air channel 6; In the air channel 6 heating tube is housed, on bung 3, is provided with exhaust outlet 7, the internal diameter of taper screen pack 5 diminishes from top to bottom gradually; Screening net 8 is equipped with at the discharging opening place of taper screen pack 5 bottoms, and paddle 2 extends in the taper screen pack 5, and on paddle 2, is distributed with multilayer stirring vane 9.
Be provided with one deck stirring vane 9 on the paddle in dry bucket 1, the stirring vane 9 in dry bucket is to link to each other with paddle 2 through connecting rod 10.
Be provided with two-layer stirring vane 9 up and down on the paddle in taper screen pack 5; In taper screen pack 5; The stirring vane 9 on upper strata connects paddle 2 through connecting rod 10, and the stirring vane 9 of lower floor directly links to each other with paddle 2, in taper screen pack 5, also is provided with the scraping blade 11 in order to strike off the Masterbatch that bonds on the screen pack; One end of scraping blade 11 connects the stirring vane on upper strata in the taper screen pack; The other end of scraping blade 11 connects the stirring vane of lower floor in the taper screen pack, and described scraping blade 11 is parallel to taper screen pack sidewall, and the spacing between scraping blade 11 and the taper screen pack sidewall is 3mm.
