Description
Technical field
The utility model relates to a kind of supporting adjusting device of chemical fibre spinning pump.
Background technology
In polyacrylonitrile (PAN) the precursor wet spinning process, the accurate control of precursor line density is the basis of the high-quality precursor of preparation, and control line density key is the accurate measurement of measuring pump.In the practice, tend to occur precise decreasing after measuring pump operation a period of time (2-2.5), the phenomenon that measurement deviation increases makes the precursor line density be difficult to control.
Spin in the spinning production more, respectively spin a measuring pump and provide transmission by a common driving shaft, operation is synchronous, and rotating speed is identical.The big main cause of line density deviation occurs, it is inconsistent to be that difference is spun a measuring pump dnockout positive and negative deviation, causes the dnockout speed difference, can't finely tune solution in subsequent handling.
Spinning pump dnockout deviation mainly is subjected to the device fabrication precision and uses effect of attrition, and the result that deviation causes is that the precursor line density is difficult to control.Particularly with in batch spinning process, when the positive and negative deviation of each measuring pump is inconsistent, adopts conventional drawing-off control method not satisfy and spin a spinning to the control requirement of line density more, need be at spinning the position separately, adopt specific process to finely tune, make and respectively spin a dnockout and be consistent as far as possible.
In order to reach this target, the method that can adopt mainly contains two kinds.
Method one: change the measuring pump transmission into separate transmission by spinning bit synchronization more, press to adjust this before the position is spun and spin a transmission frequency according to respectively spinning, reach the purpose of adjusting the dnockout amount by the rotating speed that changes pump.
Method two: increase a loop regulating system before and after measuring pump, in parallel with measuring pump, the loop caliber is determined by line density deviation size, gate valve is set on the loop regulates.
As the key equipment in the spinning production, the accuracy of manufacture of domestic part measuring pump is difficult to satisfy the requirement that high-quality precursor is produced, so the most dependence on import of this equipment.If with reference to second method, adopt the accurate adjusting device of measuring pump, then can easily revise measuring pump dnockout deviation, widen the range of application of common spinning pump greatly.
Summary of the invention
The purpose of this utility model is the measuring pump accurate adjustment corollary apparatus in a kind of wet method chemical fibre spinning process of design, spins under the identical condition of speed in control, finely tunes respectively spinning a dnockout speed, and dnockout speed is consistent, and reaches the purpose of adjusting the precursor line density.
Realize that the technical scheme that the utility model purpose is taked is: it connects mouth, charging control valve, conveying pipeline, discharging control valve by the silk head and forms, there is conveying pipeline to connect between the input and output material control valve, two silk heads connect mouth one end and are connected on the input and output material control valve, and the other end is connected on the feed pipe and discharge nozzle of measuring pump.
Good effect of the present utility model is: simple in structure, to install easy to adjustly, and maintenance cost is low, and operability is good, and daily adjusting, dismounting are very convenient; Simultaneously, part easily stifled, easily worn part is designed to articulation, can change at any time as required; Have good adaptability, can be used for the various process environments of wet spinning, can both bring into play good regulating action to various measuring pumps dissimilar, that precision is different, not only can improve the quality of products, reduce line density CV value, can also save equipment investment, increase economic efficiency.

The specific embodiment
As shown in Figure 1, it connects mouth 3, charging control valve 4, conveying pipeline 6, discharging control valve 5 by the silk head and forms, be arranged on measuring pump holddown groove 7 the insides, there is the conveying pipeline 6 of band loose joint to connect between the input and output material control valve 4,5, conveying pipeline 6 is 316 stainless steel metal pipes, be " U " font structure, the pipe two ends are respectively equipped with articulation, are connected with the outer pitch thread pairing of control valve; Two silk heads connect mouth 3 and are connected on the input and output material control valve 4,5; Input and output material control valve 4,5 is 316 stainless steel ball valves, and two ends are external screw thread, and the articulation pairing that connects on the mouth 3 with the silk head is connected; The silk head connects mouth 3 and is the silk header structure of band loose joint, and material is 316 stainless steels, size Φ 4*1.2-Φ 15*3; The charging and discharging pipe 1 of measuring pump 9,2 on respectively be provided with a circular hole, interior external threading, two silk heads connect on the feed pipe 1 and discharge nozzle 2 that mouth 3 is connected to measuring pump 9, feed and exhaust tube 1,2 is stainless steel bulb pipe, size Φ 25*8-Φ 40*8, the outer pitch thread of pipe surface cover, the inner surface of pipeline polishing.Conveying pipeline 6 and silk head connect mouth 3 sizes and are determined by measuring pump 9 deviates size, are that basic calculation is determined with bulb discharge nozzle internal diameter.Whole device is provided with 6 sealing surfaces, inner liner polytetrafluoroethylene pad, silk mouthful connection.
During normal the use, earlier with bulb charging and discharging pipe 1 and 2 with measuring pump 9 assemblings, fixing, then the silk head is connect mouth 3 and joins pad and be installed on charging and discharging pipe 1 and 2, connect input and output material control valve 4,5 successively, conveying pipeline 6 in the series connection at last.When adjusting device comes into operation in the production, charging control valve 4 standard-sized sheets, discharging control valve 5 keeps suitable aperture, measuring pump 9 outlet materials are suitably refluxed, reduce this and spin the position to the feed amount of spinning head, debugging repeatedly is according to precursor line density detected value, final definite suitable valve aperture keeps respectively spinning a feed unanimity.
