Referring to fig. 1 to 4, the utility model relates to a formaldehyde content rapid determination system for fabrics of embodiment, including the main tank body 100 and all set up in the main tank body 100: the device comprises a pretreatment box 200, a circulating heating device 300, a detection box 400, a flow detection assembly 600, a liquid supply device 500 and a main control unit 700.

A pretreatment tank 200 provided with a first water inlet, a first operation window 210; a second water inlet is formed at one side of the main tank 100; the first water inlet is connected with the second water inlet;

a circulation heating device 300 for heating the liquid in the pretreatment tank 200;

a liquid dropping device 410 is arranged on the outer side of the top of the detection box 400, and a liquid dropping port of the liquid dropping device 410 extends into the detection box 400; a first visual window 110 is arranged on the cabinet door of the main box body 100, and a second visual window 420 is arranged on one side of the detection box 400 corresponding to the first visual window 110;

a liquid supply device 500 for transferring the liquid in the pretreatment tank 200 to the detection tank 400;

a flow rate detecting assembly 600 for detecting the flow rate of the second water inlet and the flow rate of the liquid transferred from the pretreatment tank 200 to the detection tank 400;

the main control unit 700 is electrically connected to the circulation heating device 300, the liquid supply device 500, and the flow rate detection assembly 600.

The pretreatment tank 200 is mainly used for separating out formaldehyde in textiles. When the textile needs to be quickly checked, a textile sample with a specific weight can be firstly cut, and the determination of the specific weight can be directly completed by using a weighing tool. The obtained sample of the textile, i.e., the textile to be detected, is placed into the bottom of the pretreatment tank 200 through the first manipulation window 210. One side of the main tank 100 is provided with a second water inlet through which purified water or other liquid that is easily dissolved by formaldehyde can be injected into the pretreatment tank 200, and the flow rate detection assembly 600 can detect the flow rate of the second water inlet, thereby ensuring that the volume of the injected liquid into the pretreatment tank 200 is known. It should be noted that, usually, a certain mass of textile corresponds to a certain volume of liquid, so that the variables can be effectively controlled to ensure that the detection result has sufficient reference value, for example: when the same type of textiles are detected, ng samples are selected every time, and Mg purified water is correspondingly injected, so that the low formaldehyde content of products in the same type of textiles can be better determined. The circulation heating device 300 can heat the liquid in the pretreatment tank 200, and the diffusion speed and the dissolution speed of formaldehyde in the textile can be effectively improved by properly raising the temperature, so that the whole formaldehyde determination process is accelerated.

After the formaldehyde is fully dissolved, the liquid is transferred to the detection box 400 from the pretreatment box 200 through the liquid supply device 500, and the flow detection assembly 600 is used for detecting the transferred flow in the transfer process, so that the volume of the formaldehyde solution which enters the detection box 400 and is dissolved with the formaldehyde can be determined. At this time, the volume of the formaldehyde solution in the detection box 400 is known, and the formaldehyde solution is a colorless solution, then the colored detection solution can be dropped into the detection box 400 by the dropping device 410 until the liquid in the detection box 400 begins to change color and does not return to colorless. It should be noted that, in the verification process, the oxidation-reduction property of the formaldehyde solution is used, and when the liquid in the detection box 400 does not change color any more, it indicates that the liquid in the detection box 400 does not contain formaldehyde any more, and at this time, the concentration of formaldehyde in the liquid can be estimated approximately by only checking the volume of the liquid dripped by the dripping device 410, and further, the concentration of formaldehyde in a textile to be detected can be estimated. In short, if the concentration of formaldehyde in the textile is high, the concentration of formaldehyde in the solution in the pretreatment tank 200 is high, and the concentration of formaldehyde in the detection tank 400 is high, so that more detection liquid in the dripping device 410 is consumed for the same volume of formaldehyde solution.

It should be noted that the first visual window 110 and the second visual window 420 are respectively disposed on the main body 100 and the detection box 400, and the color change of the liquid can be directly checked through the visual windows, so as to stop the dripping device 410 in time. The utility model discloses a formaldehyde content spot test system compares in artifical mode that detects for in fabrics, has reduced measurement personnel and formaldehyde direct contact's chance, has reduced measurement personnel's manual operation's procedure, has reduced the requirement to measurement personnel professional skill level, can improve detection efficiency to a certain extent to reduce the health injury to measurement personnel.
