Abstract

The utility model discloses an air return filter device for a dry spinning path. The air return filter device for the dry spinning path comprises an upper filter screen with one side fixed on the upper end of a path air return opening, a lower filter screen with one side installed at the lower end of the path air return opening and an oil collecting box installed on the lower face of the lower filter screen. The air return filter device is arranged on an air return inlet. The air return filter device for the dry spinning path has the advantages that vaporized oil agent contained in the air of a workshop is effectively prevented from entering a fan circulating system, oil agent sucked in the path is prevented from being heated, decomposing and depositing in an upper air inlet, and the recovery effect and the normal operation of a fan are guaranteed to the maximum degree.

Description

A kind of dry spinning path return air filtering

Technical field

The utility model relates to a kind of spinning shaft parts, relates in particular to the return air filtering in a kind of spinning shaft.

Background technology

Development along with PU Fiber Industry, the production output of spandex is also increasing, price is also more and more lower, and for saving cost, most of corridor for spinning of urethane elastic fiber only has one to pack into air return system, generally that the spinning shaft outlet is negative pressure state, the workshop portion of air is sucked, do not leak in the workshop with the assurance solvent, but often contain the finish droplet in workshop air, this drop enters and can resolve into SiO2 in hot air circulating system in upper air inlet screen pack deposition, affects blower fan and runs well.

China Patent Publication No. is: CN201660721U, announced a kind of air return system in 2012, has the second cover air return system, this system can be for the preparation of the occasion of the high speed spinning of spandex heavy denier yarn or spandex, effectively prevented doubling phenomena, and the content that has guaranteed organic solvent in the finished fiber is less than 0.8% storage that enables the long period, we think this patent except having above-mentioned benefit also because it is autonomous system, do not participate in the blower fan circulatory system, so the finish that can avoid sucking adds the thermal decomposition sedimentation problem, but this patent is for realizing second circulatory system, a lot of energy consumption equipments have been increased, cause the power consumption of ton silk significantly to increase, so it can not significantly be promoted in spandex enterprise and come.

The utility model content

Technical problem: technical problem to be solved in the utility model is to provide a kind of a kind of dry spinning path return air filtering of avoiding finish in workshop air to be sucked into decomposing precipitation in hot air circulating system.

Technical scheme: for addressing the above problem, the utility model provides a kind of dry spinning path return air filtering: the lower filter screen of this device comprises the upper filter screen that is fixed on return air inlet upper end, bottom, path, be arranged on the path lower side return air inlet lower end and be arranged on oil collection box below lower filter screen; Wherein, described upper filter screen becomes 60 degree angles downwards with the path wall, and its horizontal width is the 1/4-1/6 of path width; Lower filter screen upwards with the path wall in angle of 45 degrees, its horizontal width is the 1/4-1/6 of path width.

Described upper filter screen is 3-10 purpose metal screen.

Described lower filter screen is comprised of oil resistance ventilation screen pack and the 3-10 purpose metal screen of corrugated plating and the combination of dull and stereotyped screen pack.

Described oil collection box is stainless steel, and 1 aperture is arranged at the bottom.

Described upper filter screen links together into as a whole with lower filter screen.

Beneficial effect: owing to adopting technique scheme, the beneficial effects of the utility model are:

1. avoid the finely ground particle substance of finish in workshop air to suck hot air circulation, improve blower fan duration of runs, improve the recovered solvent quality, reduce refining difficulty.

2. the utility model device is simple, strong operability, and cost is low, can significantly promote.

Description of drawings

Fig. 1 is a kind of structural representation of the utility model practicality.Comprising: path 1, upper filter screen 2, lower filter screen 3, oil collection box 4, return air inlet 5, horizontal width 6, path width 7.

The specific embodiment

Dry spinning of the present utility model path return air filtering, Yi Bian comprise the upper filter screen that is fixed on return air inlet upper end, path, Yi Bian be arranged on the lower filter screen of return air inlet lower end, path and be arranged on oil collection box below lower filter screen.Described upper filter screen is 3-10 purpose metal screen, becomes 60 degree angles downwards with the path wall, and its horizontal width is the 1/4-1/6 in path, preferred 1/5.Described lower filter screen is the oil resistance ventilation screen pack of corrugated plating and dull and stereotyped screen pack combination, upwards with the path wall in angle of 45 degrees, its horizontal width is the 1/4-1/6 in path, preferred 1/5.

Described oil collection box is stainless steel, and 1 aperture is arranged at the bottom, the finish that filters directly can be discharged the path.Described upper filter screen and lower filter screen are together with bolts.

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described.

as shown in Figure 1, return air filtering in a kind of spinning equipment, a double pass system that is arranged on the return air inlet place: upper filter screen 2 and lower filter screen 3, its horizontal length is and is 1/5 of path width, upper filter screen 2 is arranged on return air inlet upper end, path on one side and becomes downward 60 to spend the angle with the path wall, lower filter screen 3 is arranged on return air inlet lower end, path on one side and becomes upwards miter angle with the path wall, upper filter screen 2 and lower filter screen 3 adopt screw to be interconnected and fixed, what upper filter screen 2 was installed is 10 order metal filter screens, can tackle the silk that wafts, air-flow is passed through smoothly, lower filter screen 3 is comprised of oil resistance ventilation screen pack and the 10 purpose metal screens of corrugated plating and the combination of dull and stereotyped screen pack, oil droplet that can air in the workshop is contained filters by aperture discharge path, oil collection box lower end, but not affecting gas sucks, upper filter screen connects by screw with lower filter screen and is arranged on the wall of path, dismounting is simple, can periodic cleaning.

Should understand, this practicality example only is used for explanation the utility model and is not used in restriction scope of the present utility model, should understand in addition, after the content of having read the utility model instruction, those skilled in the art can do various changes and modification to the utility model, and these equivalent form of values fall within the application's appended claims limited range equally.
