Description

Technical Field

[0001] This utility model relates to the field of flame retardant testing technology, specifically to a fabric flame retardant testing device. Background Technology

[0002] With the increasing demand for specialized wearable and daily necessities, the demand for flame-retardant fabrics is also gradually increasing. The flame-retardant properties of these fabrics need to be tested using flame-retardant testing equipment.

[0003] The flame retardant testing device involves spraying a flame onto the fabric and then observing indicators such as the spread rate, burning time, and length of damage.

[0004] Because the fabric used in flame retardant testing is relatively small, people focus more on the testing process and results, but neglect the treatment of exhaust gas and waste generated during the testing process. Exhaust gas will cause air pollution, and combustion waste will fall onto the test platform, making it difficult for personnel to clean up. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a fabric flame retardant testing device. It collects waste gas through a gas collection box and treats it through an activated carbon adsorption system to reduce air pollution. The combustion residue falls into the collection box for unified collection, facilitating subsequent processing and reducing the labor intensity of personnel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric flame retardant testing device, comprising a test chamber, a combustion nozzle, a fuel supply system, a collection box, an activated carbon adsorption system, an air supply system, and a pair of clamps. The combustion nozzle is disposed at the top center of the test chamber, with one outer end connected to the fuel supply system. The pair of clamps are disposed at the center height of the lower part of the test chamber for horizontally clamping the fabric. A collection box is provided at the bottom of the test chamber, and the collection box can be pulled out of the test chamber. An exhaust port is provided at the top of the side wall of the test chamber, and the exhaust port is connected to the collection box through a connecting pipe. The collection box is connected to the activated carbon adsorption system through a connecting pipe. An air inlet is provided at the top of the test chamber, and the air inlet is connected to the air supply system through a connecting pipe. A door is rotatably provided on the front side wall of the test chamber, and a high-temperature resistant viewing window is provided on the door.

[0007] Temperature and pressure monitors are installed on the top.

[0008] Preferably, the bottom of the collection box and the bottom of the test chamber are connected by a sliding member.

[0009] Preferably, the collection box contains clean water.

[0010] Preferably, a filter screen is provided on the exhaust port.

[0011] Preferably, the test chamber is provided with a sleeve at the top, the combustion nozzle passes through the sleeve and is fixed by screws.

[0012] This utility model provides a fabric flame retardancy testing device, which has the following beneficial effects:

[0013] 1. This utility model collects waste gas through a gas collection box and treats it through an activated carbon adsorption system, thereby reducing air pollution. The combustion residue falls into the collection box for unified collection, which facilitates subsequent treatment and reduces the labor intensity of personnel.

[0014] 2. The collection box of this utility model contains clean water. After the fabric burns, it falls into the clean water and extinguishes immediately, reducing the emission of smoke. The fabric residue that falls into the water is not completely burned and can be collected later and used as fuel. A filter screen is installed at the exhaust port to prevent large fabric waste from entering the exhaust gas treatment system and affecting the exhaust gas treatment effect.

[0015] 3. The combustion nozzle of this utility model can move vertically within the sleeve, thereby adjusting the distance between the fabric and the nozzle, enabling the testing of results at different distances, thus improving applicability and practicality. Attached Figure Description

[0019] These are some examples, not all examples. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] like Figure 1As shown, a fabric flame retardant testing device includes a test chamber 4, a combustion nozzle 15, a fuel supply system 12, a collection box 2, an activated carbon adsorption system 1, an air supply system 10, and a pair of clamps 3. The combustion nozzle 15 is disposed at the top center of the test chamber 4, with one outer end connected to the fuel supply system 12. The pair of clamps 3 are disposed at the center height of the lower part of the test chamber 4 for horizontally clamping the fabric. A collection box 5 is provided at the bottom of the test chamber 4, and the collection box 5 can be pulled out of the test chamber 4. An exhaust port 16 is provided on the top side wall of the test chamber 4, and the exhaust port 16 is connected to the collection box 2 through a connecting pipe. The collection box 2 is connected to the collection box 2 through a connecting pipe. The connecting pipe is connected to the activated carbon adsorption system 1. The test chamber 4 has an air inlet 9 on the top, which is connected to the air supply system 10 via the connecting pipe. The test chamber 4 has a rotating door 7 on the front side wall, and a high-temperature resistant viewing window 8 on the door 7. The test chamber 4 has a temperature monitor 13 and a pressure monitor 14 on the top. The bottom of the collection box 5 is connected to the bottom of the test chamber 4 via a sliding member 6. The collection box 5 contains clean water. The exhaust port 16 has a filter screen 17. The test chamber 4 has a sleeve 11 on the top, and the combustion nozzle 15 passes through the sleeve 11 and is fixed by screws.

[0021] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0022] According to the instruction manual Figure 1 As can be seen, when using this utility model, the chamber door 7 is opened, the fabric to be tested is installed on a pair of clamps 3, and the chamber door 7 is closed. The clamps 3 can be made using existing technology. With the chamber door 7 closed, the air inlet 9 and air outlet are opened, and the combustion nozzle 15 and fuel supply system 12 are turned on. The combustion nozzle 15 sprays flames onto the fabric. The combustion nozzle 15 and fuel supply system 12 are existing technologies, and the flame size and temperature are controllable. During combustion, air can be supplied to the chamber through the air supply system 10 to prevent oxygen deficiency in the test chamber 4. The exhaust port 16 discharges the exhaust gas generated by the fabric combustion into the collection box 2. The exhaust gas in the collection box 2 enters the activated carbon adsorption system 1 for exhaust gas treatment, and is finally discharged into the air, reducing...

[0023] The combustion of the fabric produces waste residue that falls into the collection box 5. After the test, the collection box 5 is removed and disposed of uniformly. During the flame retardant test, the internal workings of the test chamber 4 are monitored by pressure monitor 14 and temperature monitor 13, and personnel can also observe through the viewing window 8 on the chamber door 7. Solenoid valves are installed on the connecting pipes of the air inlet 9 and the exhaust pipe, respectively, and are connected to the pressure monitor 14 and temperature monitor 13 in a uniform external control system. This automatically controls the air intake and exhaust volume, ensuring the stability of the internal workings of the test chamber 4, which can be achieved using existing technology. This invention collects the waste gas through the gas collection box 2 and treats it through the activated carbon adsorption system 1, reducing air pollution. The combustion waste residue falls into the collection box 5 for unified collection, facilitating subsequent processing and reducing the labor intensity of personnel.

[0024] The bottom of the collection box 5 is connected to the bottom of the test box 4 by a sliding part 6, which facilitates the placement and removal of the collection box 5. The collection box 5 is filled with clean water. When the fabric burns and falls into the clean water, it is immediately extinguished, reducing the emission of smoke. The fabric residue that falls into the water is not completely burned and can be collected later as fuel.

[0025] The exhaust port 16 is equipped with a filter screen 17 to prevent large fabric waste from entering the exhaust gas treatment system and affecting the exhaust gas treatment effect.

[0026] The test chamber 4 is equipped with a sleeve 11 on top, and the combustion nozzle 15 passes through the sleeve 11 and is fixed by screws. The combustion nozzle 15 can move vertically within the sleeve 11, thereby adjusting the distance between the fabrics and testing the results at different distances, thus improving applicability and practicality.
