Abstract
The utility model relates to a back flow type steam drafting device, which consists of branch pipe lower opening holes (1), back flow screens (2), a steam branch pipe (3), a water discharge pipeline (4) and a steam groove seam plate (5), wherein the back flow screens (2) are added under the steam groove seam plate (5) and above a steam pipeline, the steam branch pipe (3) is provided with the branch pipe lower opening holes (1), the steam is discharged out from the branch pipe lower opening holes (1) together with generated condensed water after entering the steam branch pipe (3), the discharged steam ascends around the pipe from the lower part, passes through the steam groove seam plate (5) after the back flow dispersion via the back flow screens (2) and is in contact with drafting wires to complete the uniform heating on the wires, and meanwhile, condensed water gathered through passing the steam through the back flow screens (2) and condensed water discharged from the branch pipe lower opening holes (1) are gathered to the funnel-shaped bottom part of the drafting device and are discharged through the water discharge pipeline (4). In the whole process, the steam is uniformly in contact with the wires after the back flow, the condensed water can be discharged in time, the required steam quality is ensured, and the production efficiency is improved.
Description
Affiliated field:
The utility model belongs to the chemical fibre equipment field, is specifically related to the steam drafting device in the chemical fibre post processing equipment.
Technical background:
The as-spun fibre that spinning obtains generally needs the process post processing to improve its structure, increases its mechanical property, satisfies application requirements.Postprocessing working procedures mainly contains drawing-off and HEAT SETTING.The drawing-off mode has multiple, and in the steam bath drawing-off mode, steam directly contacts the chemical fibre silk, uniformity that steam and wire connection are touched and steam do wet degree, affect that can production be carried out smoothly and the quality of finished silk quality.
In order to increase the uniformity that steam and wire connection are touched, generally be to adopt to allow steam cross porous plate, directly contact with silk again, to increase the dispersiveness of steam, silk is heated evenly.In order to keep the suitable mass dryness fraction of steam, often select for use on drafting system, installing additional steam-water separator and Automatic steam trap Trap.In order further to optimize above solution, this patent provides a kind of improved steam drafting device.
The utility model content:
The utility model purpose provides a kind of deflector type steam drafting device.
The technical solution of the utility model is: respectively add one deck baffling net below original steam drafting line of rabbet joint plate and above the whole steam pipework, in addition, a plurality of steam on steam branch pipe road are gone out the aperture, change to the below by the top.Deflector type steam drafting device mainly comprises perforate under the arm, baffling net, steam branch pipe, discharge pipe line and steam line of rabbet joint plate, and perforate under a plurality of arms is arranged at the bottom of steam branch pipe.The hole count of perforate under steam branch pipe number, arrangement mode and the arm, need decision by draft process, the baffling net is equipped with in steam line of rabbet joint plate bottom and steam branch pipe top, the order number of baffling net needs decision by draft process, discharge pipe line is equipped with in drafting system funnel-form bottom, and the device material is a metal material.
The utility model compared with prior art has following advantage:
1, the steam (vapor) outlet of steam pipework is opened below pipeline, and the water that can make small amount of steam be condensate in the pipeline below is in time got rid of, and has guaranteed required steam humidity.With advancing, steam has also been played the effect of baffling.
2, the baffling net arrangement of steam pipework top and line of rabbet joint plate below, can play the effect of baffling steam, improve the steam dispersiveness, when being touched, the final and wire connection of steam becomes even, heating is mild, avoided because of steam directly impact the silk shake that causes and heat inhomogeneous, simultaneously, the funnel-form design of baffling net and drafting system bottom also can make the easier drippage that compiles of condensed water of generation, and in time gets rid of.
3, transform simply, with low cost.
Description of drawings:
Accompanying drawing 1 is a kind of deflector type steam drafting of the utility model schematic representation of apparatus.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing 1:
Among Fig. 1: 1, perforate 2 under the arm, baffling net 3, steam branch pipe 4, discharge pipe line 5, steam line of rabbet joint plate/
As shown in Figure 1: steam enters steam branch pipe 3 by steam pipe, discharge by perforate under a plurality of arms of steam branch pipe 31 again, the condensed water that is condensate in steam branch pipe 3 bottoms is simultaneously also discharged by perforate under the arm 1, the steam of discharging is risen around pipe by steam branch pipe 3 bottoms, after the dispersion of baffling net 2 bafflings, rise again and pass steam line of rabbet joint plate 5, contact, finish even heating silk with drafted fibre.Simultaneously, the condensed water of crossing baffling net 2 bafflings rising generation reaches the condensed water of being discharged by perforate under the arm 1, compiles to drop onto drafting system funnel-form bottom, through discharge pipe line 4 discharges.
Claims (2)
1. deflector type steam drafting device, comprise: perforate under the arm (1), baffling net (2), steam branch pipe (3), discharge pipe line (4) and steam line of rabbet joint plate (5), it is characterized in that: perforate under a plurality of arms (1) is arranged at the bottom of steam branch pipe (3), baffling net (2) is equipped with in steam line of rabbet joint plate (5) bottom and steam branch pipe (3) top, and discharge pipe line (4) is equipped with in drafting system funnel-form bottom.
2. require 1 described deflector type steam drafting device according to claim, it is characterized in that: material is a metal material.
