Embodiment 1

[0020] First, add 100 grams of spinning solution into the sample delivery barrel, and put a 250-mesh circular filter cloth into the filter. After installation, the glue outlet of the filter is placed in the small hole of the sample table, the glue outlet passes through the small hole, and the upper part of the sample delivery barrel is fitted with the pressure table to ensure that the sample delivery barrel is vertically fixed. Set the control base, the first recording time is 60 seconds, and the second recording time is 300 seconds. After zeroing, place the weight on the pressure table. The weight of the weight pushes the push rod in the sample feeding barrel to release the spinning hydraulic pressure. The filter element in the filter will filter the impurities in the spinning solution. Since the impurities in the spinning solution are continuously accumulated on the filter cloth, its filtration resistance increases with the increase of the filtration time. When the resistan...

Abstract

The invention provides a spinning solution filtering value semi-automatic detector, which consists of a pressure platform, a sample platform, a weighing platform, a control base, a fixed frame, a fixed weight counterweight, a sample transfer barrel, a pressure sensor, and a filter. Firstly a spinning solution is added into the sample transfer barrel, the filter is sheathed, and the filter is internally provided with a filter core. The counterweight above the pressure platform presses the spinning solution in the sample transfer barrel and enables the spinning solution to pass through the filter, then filtered spinning solution flows into a beaker on the weighing platform, the control base is equipped with buttons and a display screen, and the sample platform is equipped with the pressure sensor. Through the setting, the control base can record the filtered liquid flowing into the beaker within a fixed period of time, and supports recording of 1-3 groups of data. And after filtering, the spinning solution filtering value can be obtained by observing the recorded data. The semi-automatic detector provided by the invention has weighing, automatic timing and other functions, has simplicity and visualization characteristics beneficial to improvement of inspection efficiency and precision, and is of important significance for improvement of the production process and product stability.

Description

technical field [0001] The invention belongs to the field of spinning inspection devices, in particular to a semi-automatic device for detecting the filtration value of spinning liquid. Background technique [0002] Solvent spinning is an important spinning method for chemical fibers, which mainly refers to dissolving spinning raw materials into spinning liquid, and spinning after pre-spinning treatments such as filtration and degassing. Throughout the process, the quality of the spinning solution is the main factor affecting the filtration, degassing and spinning processes. The quality of the spinning solution also determines the production cost. Spinning liquid with many impurities (insoluble matter, gel, etc.) leads to slow filtration speed and frequent replacement of filter cloth, which also affects the quality of fiber products. Therefore, the inspection of spinning solution is an essential link in the chemical fiber industry. There are various methods to test the qu...
