Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, in particular to a multi-station semi-automatic filtration device for dissolving fiber content in textiles. Background Art

[0002] Textile fiber composition and content are key indicators for quality control of textiles and their products. Currently, many countries have incorporated fiber content labeling into mandatory standards, making it a mandatory labeling requirement for all textiles and their products when they are marketed and a key component of various market supervision and inspections.

[0003] Accurately labeling fiber composition and content requires accurate measurement. To this end, textile manufacturers, testing agencies, and national regulatory authorities expend significant manpower and resources on testing and regulating fiber composition and content. The most commonly used method for quantitative fiber content testing is the chemical dissolution method. This method works as follows: Based on the test requirements, a certain amount of sample is taken from the textile (a certain mass, a cycle, or based on yarn type, etc.), dried and weighed. Different reagents, such as 75% sulfuric acid or 20% hydrochloric acid solution, are then selected based on the fiber composition of the sample to dissolve the corresponding components under specific conditions (for example, for a polyester and cotton blend, 75% sulfuric acid at 50°C can be used to dissolve the cotton fibers). The remaining sample is removed, filtered, dried, and weighed. The remaining weight is then calculated based on the official moisture regain to determine the specific cotton and polyester fiber content.

[0004] Existing chemical dissolution quantitative analysis methods require manual operation throughout the entire process. Operators must manually collect water to rinse the dissolved sample during filtration, which is labor-intensive. Because the reagent solutions used in this method are typically strong acids or bases, even the slightest operator error can cause personal injury. Therefore, replacing the post-dissolution sample cleaning process with a machine can effectively reduce labor intensity and safety risks. Summary of the Invention

[0005] The purpose of the present invention is to reduce the labor intensity of dissolving personnel and alleviate potential safety hazards, and to provide a multi-station semi-automatic filtration device for the dissolution process of textile fiber content.

[0006] The technical solution of the present invention is as follows: a multi-station semi-automatic filtration device for dissolving textile fiber content comprises: a main unit, a water storage tank, a neutralizing liquid storage tank, a liquid conduit, a filter crucible, a vacuum pump, and a waste liquid tank. The water storage tank is connected to a faucet; the water storage tank and the neutralizing liquid storage tank are each connected to the filter crucible via a liquid conduit; the filter crucible has several stations, which are connected to the vacuum pump and the waste liquid tank via the liquid conduit.

[0007] Furthermore, all accessories of the filtration device are made of corrosion-resistant materials.

[0008] Furthermore, the liquid inlet pump contained in the main body of the filtration device adopts a peristaltic pump, and the liquid discharge pump adopts a peristaltic pump or a diaphragm pump; the main body is connected to the liquid inlet pump with an anti-corrosion three-way solenoid valve, and the type of washing liquid (water / neutralizing liquid) each time can be controlled by setting the program; the main body can set the cleaning program, including the amount of liquid aspirated each time and the interval time of liquid aspiration; there are three buttons in the main body, the start button controls the water inlet / neutralizing liquid, the liquid discharge button controls the liquid discharge, and the stop button can interrupt the liquid inlet and liquid discharge process.

[0009] Furthermore, the water storage tank and the neutralizing liquid storage tank of the filtration device should have covers.

[0010] Furthermore, the filtering crucible of the filtration device is made of corrosion-resistant material, and the pore size can effectively prevent the fibers from falling.

[0011] Furthermore, the filtering crucible of the filtration device should be fixed on a rack to ensure stability.

[0012] Furthermore, the vacuum pump of the filtration device is a drainage pump, and the other end of the drainage pump is connected to a waste liquid collection device.

[0013] Furthermore, the filtration device can increase or decrease the number of filtration crucibles to meet test requirements.

[0014] Furthermore, the power of the liquid inlet pump of the main body of the filtration device, the number of working positions of the filtering crucible, and the power of the liquid discharge vacuum pump must match each other.

[0015] Furthermore, the control system of the filtration device includes: a main control circuit arranged in the main body of the tester, a PLC control system arranged in the outer cover of the filtration device, and an operation panel to complete the control of the entire filtration process.

[0016] By adopting the above scheme, the present invention realizes the operation of simultaneously cleaning and dissolving test samples at multiple stations through the host control system. The independent pipeline of each station prevents cross-influence between samples, which can effectively improve the test efficiency, reduce test operations, reduce the labor intensity of test personnel, ensure the safety of operators, and meet the use needs of the laboratory.
