Description

Technical Field

[0001] This utility model relates to the field of steel wire rope fiber core quality testing technology, specifically a device for measuring the moisture regain and oil content of steel wire rope fiber core. Background Technology

[0002] The fiber core of steel wire rope is a natural fiber core, mainly made of sisal and jute twisted together. The fiber core of steel wire rope mainly plays the role of support and oil storage in steel wire rope. Its moisture regain rate and oil content are very important to the performance of the fiber core of steel wire rope.

[0003] Moisture regain test: Cut a sample representing the entire cross-sectional area from the center of a steel wire rope fiber core with a mass of at least 100 grams. The mass of the sample m2 is approximately 50 grams. Add xylene or an appropriate amount of benzene to the sample. After fractional distillation, distill the water contained in the sample and condense it in a graduated receiver to obtain the mass of water contained in the sample m4. Calculate the moisture regain using the formula: M(%) = (m2-m4) / m4*100. The moisture regain M of the steel wire rope fiber core can be obtained.

[0004] Oil content detection: A sample representing the entire cross-sectional area is cut from the center of a steel wire rope fiber core with a mass of at least 100 grams. The mass m1 of a sample used to determine the oil content is between 20-30 grams, and the mass m2 of a sample used to determine the water content is approximately 50 grams. Xylene or a suitable amount of benzene is added to the m2 sample. After fractional distillation, the water contained in the sample is distilled and condensed in a graduated receiver to obtain the mass m4 of water contained in the sample. The mass m5 of water present in the m1 sample is calculated using the formula m5 = m1 / m2 * m4. The first sample m1 is dispersed, weighed, and then placed into a new extraction bottle of known mass. The extraction bottle is then dried in a drying oven. Dry for at least 2 hours at 105°C. Cool the extraction flask in a desiccator for 2 hours and determine its mass. Pour 150 ml of dichloromethane into the flask and extract the contents of the flask using a Soxhlet extraction apparatus until the extraction medium flows out in a colorless form or, if a colorless impregnating agent is present, until the sample extracted from the extract evaporates without residue. After extraction, evaporate the solvent, leaving a small amount. Evaporate the residual extractant in a drying oven at 105°C until a constant mass is obtained. Cool the flask in a desiccator for 2 hours and weigh the extracted portion to obtain the mass m3 (excluding water). Then, use the formula: M(%) = m3 / (m1-m3-m5)*100 to calculate the oil content.

[0005] In the process of measuring oil content, drying and cooling are required before and after extraction, and this process takes a long time, which affects the efficiency of oil content measurement. Furthermore, the oil content measurement data includes the mass of water in the sample being tested. Measuring moisture regain and oil content separately would result in repeated operations and waste of testing resources. Utility Model Content

The housing 1 is fixed on the base 2, the sample weighing box 3 is fixed on the top of the housing 1, the controller 4 is fixed on the inner wall of the housing 1, the heating seat A5 and the heating seat B8 are fixed on the base 2, the distillation device 6 is fixed above the heating seat A5, the Soxhlet extractor 9 is fixed above the heating seat B8, the condenser 7 is fixed on the top of the housing 1, the dryer 10 is fixed on the upper right of the housing 1, and the cooler 11 is fixed below the dryer 10. The controller 4 is electrically connected to the sample weighing box 3, the heating seat A5, the condenser 7, and the heating seat B8.

[0023] refer to Figure 2 and Figure 3 Distillation tube 601 is fixed inside housing 1. Distillation tube 601 is connected to condenser tube 602. A moisture collector 603 is connected below condenser tube 602. Moisture collector 603 is fixed on base 2. A scale bar 604 is engraved on moisture collector 603.

[0024] By electrically connecting the controller 4 to heating base A5, heating base B8, and condenser 7, the moisture regain is measured. The controller 4 controls the heating base A5 to heat the distillation device 6 and controls the condenser 7 to condense the water into the water collector 604. The volume of water contained is sensed and measured by the photosensitive sensor 605 and input into the controller. The controller 4 converts this into a mass m4 and calculates the moisture regain according to the formula. To measure the oil content, the controller controls the heating base A5 and heating base B8 to heat simultaneously. The water content m5 is determined by the formula based on the above steps.

After extraction is completed, the flasks are dried again in the dryer 10 and then placed in the cooler 11 for cooling and weighing to obtain the weight of the flask containing the extract, thereby obtaining the extract mass m3. The flasks to be used for extraction are prepared in the cooler 11 before the oil content measurement work begins, saving the preparation time of the extraction flasks during the extraction process. In the case of multiple extractions, the empty flasks and the flasks containing the extract can be dried, cooled and weighed at the same time, saving a lot of time. At the same time, the weight sensor 1102 is electrically connected to the controller 4, which can reflect the extract mass m3 on the control display 12. According to the oil content calculation formula, the controller completes the calculation and determination of the oil content, which is convenient and fast.

[0027] How to use

[0028] The working principle and usage process of this utility model are as follows: To determine the moisture regain, a sample section is placed in the sample weighing box 3 and weighed (m2). Then, it is placed in a distillation flask, and xylene or a suitable amount of benzene is added. The controller 4 controls the heating seat A5 to heat the distillation device 6 and controls the condensing device 7 to condense the water, causing it to condense in the water collector 603. Xylene is immiscible with water and floats on the water surface. The volume of water contained is sensed and measured by the photosensitive sensor 605 and input into the controller 4. The controller 4 converts this into a mass (m4). According to the formula M(%) = (m2 - m4) / m4 * 100, the moisture regain M of the steel wire rope fiber core can be obtained. To determine the oil content, two samples are taken and placed in the sample weighing box 3, weighed (m1 and m2 respectively). The mass of water contained in m2 is measured according to the above steps (m4). According to the formula m5 = m1 / The mass of water (m5) in the sample with mass m1 is calculated using m2*m4. Then, sample m2 is placed in Soxhlet extractor 9. The pre-treated beaker placed in cooler 11 is removed and its weight is recorded. 150ml of dichloromethane is poured into a flask and connected to the bottom of Soxhlet extractor 9. Controller 4 controls heating seat B8 to heat and extract the extract. Then, the beaker containing the extract is placed in dryer 10 to dry it. It is then removed and placed in cooler 11 to cool. The weight is detected by weight sensor 1102 in cooler 11. The weight of the extract is subtracted from the weight of the beaker to calculate the mass m3 of the extract. The oil content is then calculated using the formula: M(%) = m3 / (m1-m3-m5)*100. The entire calculation process is completed by the control program in controller 4 and the results are output to control display 12, which is convenient and fast.
