Description

Technical Field

[0001] This utility model relates to the field of combustion testing, and in particular to a multifunctional combustion performance tester. Background Technology

[0002] An existing patent (publication number: CN207851009U) discloses a combustion performance tester, including a combustion reaction chamber and a cabinet door. The cabinet door is rotatably connected to the combustion reaction chamber via a hinge. The end of the cabinet door away from the hinge is connected to the combustion reaction chamber via an electromagnetic lock. A base is fixedly connected to the bottom of the combustion reaction chamber. A gas supply pipe is provided above the base. A flame nozzle is connected to the output end of the gas supply pipe. The flame nozzle is located above the base. A fixing block is fixedly connected to the bottom of the flame nozzle. A fixing rod is fixedly connected to the top of the base. A slot corresponding to the fixing rod is provided in the fixing block. The fixing rod is rotatably connected to the inner wall of the slot via a first rotating shaft. A second rotating shaft is provided in the base. One end of the second rotating shaft is rotatably connected to the inner wall of the base. However, the distance between the "flame nozzle" and the "mounting frame" in this device is fixed. It cannot adjust the distance between the nozzle and the sample according to different test standards such as the material and thickness of the sample to be tested. This makes it impossible to ensure that the flame can fully act on the sample surface, affecting the accuracy of the test results and presenting a drawback. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a multifunctional combustion performance tester that offers convenient sample fixing and installation, easy ash collection tray cleaning, and improved efficiency in combustion performance testing. Furthermore, it allows for adjustments to the sample's fixing height and testing distance from the burner based on actual testing standards such as sample material, length, and thickness, ensuring sufficient flame contact with the sample surface and increasing the accuracy of test results.

[0004] The objective of this utility model is achieved through the following technical solution: A multifunctional combustion performance tester includes a combustion reaction chamber, a control panel, a chamber door, an ash collection tray, a sample rack, fixing strips, clamps, and threaded rods. The control panel is located on the right side of the combustion reaction chamber. A burner is located inside the combustion reaction chamber. The chamber door connects to the outside of the combustion reaction chamber, and an observation window is located in the center of the door. The sample rack is fitted inside the combustion reaction chamber. A control block is connected to the upper part of the sample rack. The combustion reaction chamber has a slide rail, and the control block is adapted to the slide rail and slides within the slide rail. A control rod is sequentially connected to the combustion reaction chamber and the control block, and is threaded to the control block. A motor is connected to the outer end of the control rod, and the motor is connected to the combustion reaction chamber. The ash collection tray is connected to the lower part of the sample rack, and the bottom of the ash collection tray is fitted to the combustion reaction chamber. The ash collection tray has slots on both sides, and a locking strip is located inside the sample rack, adapting to the slots and connecting to them.

[0005] The sample holder of this utility model has multiple brackets on both sides, the brackets are connected to fixing strips, the fixing strips have insert rods at the bottom, the brackets have insertion holes, the insert rods are adapted to the insertion holes, the insert rods pass through the insertion holes, and the fixing strips have baffles on both sides, the baffles are attached to the brackets. Beneficial effects

[0006] In the fabric combustion performance test of this utility model, the upper end of the sample to be tested is first passed through the through hole of the fixing strip, and the clamp is clamped by rotating the knob. The clamp and the fixing strip are respectively provided with interlocking serrations on opposite sides to enhance the fixing effect of the upper end of the fabric and prevent it from falling off during the test. Then, according to the length of the sample to be tested, the fixing strip is placed in the bracket at a suitable height. The bracket is increased with the baffle and the insertion rod to increase the lateral and longitudinal limiting support of the fixing strip, ensuring its support stability and preventing the sample from slipping during the test. Then, according to the actual test standards such as the sample material and thickness, the test distance between the sample holder and the burner is adjusted to a reasonable position by starting the motor. Finally, the chamber door is closed, and the burner is started through the control panel to conduct the combustion performance test. During the test, the combustion of the sample can be observed through the observation window, and the ash and debris after the sample burns fall into the ash collection tray for easy cleaning.

[0007] This utility model features a separate design for the sample holder, ash collection tray, and fixing strip, making it convenient to pick up and put in. It facilitates sample fixing and quick cleaning of the ash collection tray. Through embedded engagement, it provides a force support point for the synchronous displacement of the ash collection tray and fixing strip by the sample holder, thus fixing the relative positions of the ash collection tray, burner, and sample holder. When the position of the sample holder moves, there is no need to readjust the position of the ash collection tray and fixing strip, simplifying the operation steps and improving the efficiency of combustion performance testing.

[0008] The control block of this utility model is positioned by a threaded connection between the control rod and the control block. When the control rod is rotated by the motor, the control block, the sample holder and the fixing bar move in a synchronous lateral linear displacement. This allows the test distance between the nozzle and the sample to be adjusted according to different test standards such as the material and thickness of the sample to be tested, ensuring that the flame fully acts on the sample surface and increasing the accuracy of the test results.

[0009] This utility model offers convenient sample fixing and installation, easy ash collection tray cleaning, and improved efficiency in combustion performance testing. Furthermore, it allows for adjustments to the fixing height and testing distance between the sample and the burner nozzle based on actual testing standards such as sample material, length, and thickness, ensuring sufficient flame contact with the sample surface and increasing the accuracy of test results.

The chamber door 03 is connected to the outside of the combustion reaction chamber 01, and an observation window 04 is located in the middle of the chamber door 03. The sample rack 07 is fitted inside the combustion reaction chamber 01, and a control block 09 is connected to the upper part of the sample rack 07. The combustion reaction chamber 01 has a slide rail 1. 1. The control block 09 is adapted to the slide rail 11 and is connected to the slide rail 11. The control block 09 slides within the slide rail 11. The control rod 08 is sequentially connected to the combustion reaction chamber 01 and the control block 09. The control rod 08 is threaded to the control block 09. The outer end of the control rod 08 is connected to the motor 10, and the motor 10 is connected to the combustion reaction chamber 01. The lower part of the sample holder 07 is connected to the ash receiving tray 06. The bottom of the ash receiving tray 06 is attached to the combustion reaction chamber 01. The ash receiving tray 06 has slots 13 on both sides. The inner side of the sample holder 07 has a retaining strip 12. The retaining strip 12 is connected to... The slot 13 is adapted to the material, and the clip 12 connects to the slot 13. During the fabric combustion performance test, the upper end of the sample to be tested is first passed through the through hole 17 of the fixing strip 15, and the clamping plate 16 is driven to clamp it by rotating the knob 20. The clamping plate 16 and the fixing strip 15 are respectively provided with interlocking serrations on opposite sides to enhance the fixing effect on the upper end of the fabric and prevent it from falling off during the test. Then, according to the length of the sample to be tested, the fixing strip 15 is placed in the bracket 14 of a suitable height, and is secured by the baffle 25 and the insertion rod 22. The bracket 14 provides lateral and longitudinal limiting supports for the fixing strips 15, ensuring its support stability and preventing sample slippage during testing. Then, based on the actual testing standards such as sample material and thickness, the test distance between the sample holder 07 and the burner 05 is adjusted to a reasonable position by starting the motor 10. Finally, the chamber door 03 is closed, and the burner 05 is started through the control panel 02 to conduct the combustion performance test. During the test, the combustion of the sample can be observed through the observation window 04, and the ash and debris after the sample combustion falls into the ash collection tray 06 for easy cleaning.

[0017] Example 2: The sample holder 07 of this utility model has multiple brackets 14 on both sides, and the brackets 14 are connected to fixing strips 15. The lower part of the fixing strips 15 has a rod 22, and the brackets 14 have insertion holes 23. The rods 22 are adapted to the insertion holes 23 and pass through the insertion holes 23. The fixing strips 15 have baffles 25 on both sides, and the baffles 25 fit the brackets 14. The sample holder 07, the ash receiving tray 06, and the fixing strips 15 are all designed separately, which is convenient for picking up and putting in. It is convenient for fixing and installing samples and for quickly cleaning the ash receiving tray 06. At the same time, through embedded engagement, it provides a force support point for the sample holder 07 to drive the ash receiving tray 06 and the fixing strips 15 to move synchronously, so that the relative positions of the ash receiving tray 06, the burner 05 and the sample holder 07 are fixed. When the position of the sample holder 07 moves, there is no need to readjust the position of the ash receiving tray 06 and the fixing strips 15, which simplifies the operation steps and improves the efficiency of combustion performance testing.

[0018] Example 3: The fixing strip 15 of this utility model has a through hole 17 and a side through hole 18, which is adapted to the clamping plate 16. The clamping plate 16 passes through the side through hole 18. The clamping plate 16 has positioning support plates 24 at both ends. The fixing strip 15 has mounting support plates 21 on both sides. The control block 09 is positioned and connected to the control rod 08 by a thread, so that when the motor 10 drives the control rod 08 to rotate, the control block 09, the sample holder 07 and the fixing strip 15 will move synchronously in a lateral linear displacement. This allows the test distance between the nozzle 05 and the sample to be adjusted according to different test standards such as the material and thickness of the sample to be tested, ensuring that the flame fully acts on the sample surface and increasing the accuracy of the test results.

[0019] Example 4: The threaded rod 19 of this invention passes sequentially through the mounting plate 21 and the positioning plate 24. The threaded rod 19 is threadedly connected to the positioning plate 24. Both ends of the threaded rod 19 are connected to knobs 20, which fit against the mounting plate 21. This device makes sample fixing and installation convenient, and the ash collection tray 06 is easy to clean. It improves the efficiency of combustion performance testing and allows for adjustments to the fixing height and testing distance between the sample and the nozzle 05 according to the actual testing standards such as sample material, length, and thickness. This ensures that the flame fully acts on the sample surface and increases the accuracy of the test results.

[0020] Example 5: Installation steps: First, assemble the control structure of the sample holder 07. First, place the control block 09 into the slide rail 11. Then, connect the control rod 08 to the combustion reaction chamber 01 and the control block 09 in sequence. The control rod 08 is connected to the control block 09 by a thread. Then, install and fix the motor 10 to the outside of the combustion reaction chamber 01 and drive it to the control rod 08. Next, place the sample holder 07 into the combustion reaction chamber 01 and fix it to the control block 09. The upper surface of the sample holder 07 should be in contact with the top surface of the combustion reaction chamber 01, and the lower surface of the sample holder 07 should be in contact with the bottom surface of the combustion reaction chamber 01. Finally, place the ash collection tray 06 into the sample holder 07 and push it down until its lower surface is in contact with the combustion reaction chamber 01. After the bottom surface of the reaction chamber 01 is in contact with the sample holder 07 and the clip 12 is embedded in the slot 13, the fixing strip 15 is assembled. First, the clamp 16 is inserted into the fixing strip 15 through the side through hole 18 until the positioning support plate 24 corresponds to the position of the mounting support plate 21. Then, the threaded rod 19 is passed through the mounting support plate 21 and the positioning support plate 24 in sequence, and the threaded rod 19 is positioned and connected to the positioning support plate 24 through the thread. Then, the knob 20 is placed outside the mounting support plate 21 and fixedly connected to the threaded rod 19. Finally, the fixing strip 15 is placed on the upper part of the bracket 14, and the inner surface of the baffle 25 is in contact with the bracket 14. The insertion rod 22 passes through the insertion hole 23 to complete the installation.
