Description

Technical Field

[0001] This utility model relates to the field of fiber composition detection technology, and specifically to a fiber composition detection device based on dual-path flow control. Background Technology

[0002] Currently, the main methods for detecting the composition of fiber materials are manual separation (time-consuming), microscopy (requires professional experience), infrared spectroscopy (expensive equipment), and traditional methods.

[0003] Traditional chemical dissolution methods utilize the selective dissolution property of concentrated sulfuric acid on cotton fibers (cellulose) while preserving polyester fibers (polyester fibers). This involves diluting concentrated sulfuric acid with water to create a specific concentration of sulfuric acid solution, adding a quantitative amount of fiber sample for dissolution, and then collecting and weighing the undissolved residue (i.e., the fiber component). The fiber percentage is determined by calculating the ratio of the residue's weight to the original fiber sample weight. However, this method has several drawbacks: First, manual dilution of the sulfuric acid can introduce errors in flow rate, leading to incomplete dissolution and affecting the accuracy of fiber percentage detection. Second, manual stirring is required, which is labor-intensive, time-consuming, and inefficient. Third, concentrated sulfuric acid is highly corrosive, posing significant safety risks during operation.

[0004] In order to improve the safety and ease of operation of the chemical dissolution method for detecting fiber composition, the applicant has innovatively designed the method described in this application. Utility Model Content

[0005] The purpose of this invention is to provide a fiber composition detection device based on dual-channel flow control, which has the characteristics of simple structure, convenient operation, good safety and strong practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fiber composition detection device based on dual-path flow control includes a cabinet and a cabinet door. The cabinet contains a sulfuric acid tank and a pure water tank. A reaction tank is located below the sulfuric acid tank and the pure water tank. A first liquid addition pipe is located at the bottom of the sulfuric acid tank, and a second liquid addition pipe is located at the bottom of the pure water tank. Both the first and second liquid addition pipes extend into the reaction tank. A support platform is located at the bottom of the cabinet. A waste liquid tank is located on one side of the support platform. The reaction tank is located on the support platform and connected to the waste liquid tank through an outlet pipe. Control valves are installed on the first liquid addition pipe, the second liquid addition pipe, and the outlet pipe. Flow meters are also installed on the first and second liquid addition pipes.

[0008] Preferably, a stirring device is provided above the reaction tank.

[0009] The stirring device includes a stirring motor and a stirring shaft, with the lower end of the stirring shaft extending into the reaction tank and equipped with a stirring paddle.

[0010] The top surface of the cabinet is equipped with filling ports and covers corresponding to the sulfuric acid tank and the pure water tank, respectively.

[0011] The cabinet is equipped with a control display panel.

[0012] The support platform has a hollow structure, and a rechargeable battery and controller are installed inside.

[0013] The support platform contains a wire harness tube that extends out of the support platform and into the upper part of the cabinet.

[0014] This utility model effectively achieves dual-path flow control by installing a sulfuric acid tank, a pure water tank, a reaction tank, and a waste liquid tank inside the cabinet, and by installing flow meters and control valves on the first liquid addition pipe of the sulfuric acid tank and the second liquid addition pipe of the pure water tank. By controlling and measuring the addition of sulfuric acid and water, the addition is more accurate and convenient, and the operation inside the cabinet is safer.

[0015] Preferably, by installing a stirring device inside the cabinet, stirring and dissolving become more convenient. A control display panel is installed on the cabinet, and a power supply and controller are located inside the support platform. The connection lines between the power supply and controller, the flow meter, the control valve, and the control display panel are constrained by a cable harness to prevent tangling. The control display panel allows for convenient control of the addition rate and amount of sulfuric acid and water, as well as the stirring speed and time. The entire process from dilution to stirring and dissolving is completed automatically, reducing manual intervention. Furthermore, the order of adding sulfuric acid and water can be controlled logically to avoid incorrect addition, further improving the safety of the testing operation.

[0016] This utility model has the characteristics of simple structure, convenient operation, good safety, strong practicality, and good use effect, and is worth promoting and using widely. Attached Figure Description
