Abstract
The utility model relates to the technical field of a chemical fiber auxiliary production device, in particular to a chemical fiber slice drying system. A vacuum drying system is connected with a Roots pump through a vacuum valve, the Roots pump is connected with a pneumatic boosting valve, the pneumatic boosting valve is connected with an air injection pump, the air injection pump is also provided with a differential pressure valve, the air injection pump is connected with a water level meter, the water level meter is connected with a water ring pump, and the water ring pump is connected with a steam and liquid separator. The chemical fiber slice drying system has the advantages that by adopting the vacuum valve, when the vacuum valve is closed, a machine unit stops running, so certain vacuum degree of the drying system is maintained; by adopting the automatic pneumatic boosting valve, so water in a water ring pump system is prevented from backfilling into the Roots pump and the vacuum drying system when the machine unit suddenly stops; by adopting the differential pressure valve, the pre-pumping time before the normal operation of an air pump is shortened; and by adopting the water level meter, the function of a check valve is realized, and the backflow of the water in the water ring pump is prevented.
Description
Technical field
The utility model relates to chemical fibre and produces servicing unit technical field, specifically a kind of chemical fibre chips drying system.
Background technology
The production process of fiber product is: low molecule-macromolecule-make band shape-section-drying-reel off raw silk from cocoons-drawing-off, heating-weaving-finished product, one of them important operation is that drying is carried out in the section of 5 * 5 * 5 sizes, in order to reel off raw silk from cocoons, desirable situation is that to make water content be zero in the drawing process, in fact owing to can not reach this purpose, so require water content to be not more than 0.02%, if moisture content surpasses this requirement, want to reel off raw silk from cocoons under the HTHP, macromolecule is decomposed, affect the intensity of product, to the requirement of moisture, will have a strong impact on like this intensity of product when present drying system is difficult to satisfy section.
Therefore, design a simple in structurely, easy to use for the deficiency that overcomes above-mentioned technology, slicing process is carried out drying, guarantee a kind of chemical fibre chips drying system of the intensity of product, just inventor's problem to be solved.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model provides a kind of chemical fibre chips drying system, and it is simple in structure, and is easy to use, and slicing process is carried out drying, guarantees the intensity of product, and extraordinary practical value is arranged.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of chemical fibre chips drying system, comprise vacuum drying system, lobe pump, vacuum valve, valve for pressure difference, the Pneumatic Pressure valve, vapour liquid separator, atmospheric jet pump, water-level gauge, water ring pump, it is characterized in that: described vacuum drying system is connected with lobe pump by vacuum valve, lobe pump is connected with the Pneumatic Pressure valve, the Pneumatic Pressure valve is connected with atmospheric jet pump, also be provided with valve for pressure difference on the atmospheric jet pump, atmospheric jet pump is connected with water-level gauge, water-level gauge is connected with water ring pump, and water ring pump is connected with vapour liquid separator.
Further, described lobe pump quantity is two, and two lobe pumps are connected in parallel.
The beneficial effects of the utility model are:
1, the utility model adopts the vacuum valve design, closes vacuum valve, and unit is out of service, the vacuum that the system that can keep dry is certain.2, the utility model adopts the design of automatic pneumatic pressurizing valve, and the water when preventing that unit from stopping suddenly in the water ring pump system pours in down a chimney in lobe pump and vacuum drying system.3, the utility model adopts the valve for pressure difference design, when unit brings into operation, start first water ring pump, produce gradually pressure reduction at the valve for pressure difference two ends, when reaching certain value, valve is opened automatically, make that most of gas flows to water ring pump through this valve in the system, when atmosphere flows to water ring pump by atmospheric pump gradually, the valve for pressure difference pressure at two ends reduces again gradually, atmospheric pump begins normal operation immediately, and the effect of valve for pressure difference is in order to shorten front the finding time in advance of atmospheric pump normal operation.4, the utility model adopts the water-level gauge design, plays check (non-return) valve, prevents the aqueous reflux of water ring pump.
