DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figures 1 to 5 A combustion performance testing device for building thermal insulation materials includes a combustion chamber 1. A clamping device 5 and an ignition device 7 are provided inside the combustion chamber 1. The clamping device 5 can clamp the thermal insulation material test block to be tested, thereby facilitating the combustion performance test. The ignition device 7 can ignite the thermal insulation material test block, thereby facilitating the combustion performance test.

[0028] A rotating shaft 8 is rotatably mounted on the combustion chamber 1, and a door body 2 is fixedly mounted on the rotating shaft 8. When the door body 2 is closed, the interior of the combustion chamber 1 becomes a closed space. When the door body 2 rotates, the rotating shaft 8 rotates synchronously.

[0029] A receiving plate 4 is slidably mounted inside the combustion chamber 1, and a lower slag trough 13 is provided on the receiving plate 4;

[0030] A slag trough 11 is provided at the bottom of the combustion chamber 1, and a slag discharge chamber 12 is fixedly installed at the bottom of the slag trough 11;

[0031] A mounting plate 9 is fixedly mounted inside the combustion chamber 1 , and a cleaning blade 10 is fixedly mounted on a side of the mounting plate 9 facing the receiving plate 4 . The cleaning blade 10 is in direct contact with the receiving plate 4 .

[0032] When the receiving plate 4 is moved, since the cleaning scraper 10 is in direct contact with the receiving plate 4, the cleaning scraper 10 can intercept the debris and residue on the receiving plate 4 so that it will not move synchronously with the movement of the receiving plate 4 until the debris and residue fall directly into the lower slag trough 13.

[0033] It is worth noting that the cleaning scraper 10 is located directly above the slag trough 11 , so when the lower slag trough 13 is aligned with the slag trough 11 , debris and residue can smoothly fall into the slag trough 11 and be discharged through the slag discharge chamber 12 .

[0034] When the residue still needs to be inspected, a receiving structure such as a tray can be placed at the bottom of the residue discharge chamber 12; when the residue is not needed, a trash can can be placed directly at the bottom of the residue discharge chamber 12.

[0035] It is worth noting that when filter paper is used during testing, the sizes of the slag trough 11, the slag discharge chamber 12 and the lower slag trough 13 can be adjusted according to actual needs.

[0036] A tooth plate 16 is fixedly mounted on the bottom of the receiving plate 4 , and a gear 15 meshing with the tooth plate 16 is rotatably mounted at a corresponding position of the combustion chamber 1 .

[0037] When the gear 15 is rotated, the tooth plate 16 is moved due to the meshing relationship, and then the receiving plate 4 is moved out, which facilitates the automatic cleaning of debris and residues.

[0038] A reversing speed increaser 14 is provided inside the combustion chamber 1. The input shaft of the reversing speed increaser 14 is connected to the rotating shaft 8, and the output shaft of the reversing speed increaser 14 is fixedly connected to the center of the gear 15. It is worth noting that the output shaft of the reversing speed increaser 14 rotates in the opposite direction to the input shaft.

[0039] When the door body 2 is rotated, the rotating shaft 8 will rotate. By reversing the speed increaser 14, the gear 15 can rotate more circles, driving the tooth plate 16 and the receiving plate 4 to move, so that when the door body 2 is opened, the receiving plate 4 can be automatically moved out for cleaning.

[0040] A cleaning brush 17 is fixedly mounted on the bottom of the receiving plate 4 . The cleaning brush 17 is located inside the lower slag trough 13 and is in direct contact with the inner bottom of the combustion chamber 1 .

[0041] When the receiving plate 4 moves, the cleaning brush 17 can move the debris that accidentally falls into the lower slag trough 13, thereby ensuring the cleanliness of the bottom of the combustion chamber 1 and facilitating use.

[0042] A fixed plate 6 is fixedly mounted inside the combustion chamber 1, and an ignition device 7 is slidably mounted on the fixed plate 6. It is worth noting that the movement of the ignition device 7 can be controlled from outside the combustion chamber 1, so that after the angle and height of the flame are adjusted and the door body 2 is closed, the ignition device 7 can be moved so that the ignition device 7 contacts the insulation material test block on the clamping device 5 to perform the ignition activity, which is safer and more efficient.

[0043] An observation window 3 is inlaid on the door body 2, through which the internal combustion situation can be observed in real time, facilitating timely control.

[0044] The working process of the present utility model is as follows: when operating, first open the door body 2, then fix the insulation material test block to be tested inside through the clamping device 5, then adjust the angle and height of the flame on the ignition device 7, and then close the door body 2 to move the ignition device 7, so that the ignition device 7 contacts the insulation material test block on the clamping device 5 to perform the ignition activity.

[0045] When the activity is completed, the door body 2 is opened. When the door body 2 is rotated, the rotating shaft 8 will rotate. By reversing the speed increaser 14, the gear 15 can rotate more circles. The tooth plate 16 will move through the meshing relationship, and then the receiving plate 4 will move out.

[0046] When the receiving plate 4 moves, since the cleaning scraper 10 is in direct contact with the receiving plate 4, the cleaning scraper 10 can intercept the debris and residue on the receiving plate 4 so that it will not move synchronously with the movement of the receiving plate 4 until the debris and residue fall directly into the lower slag trough 13, and then smoothly fall into the slag trough 11 and are discharged through the slag discharge chamber 12.

[0047] When the residue still needs to be inspected, a receiving structure such as a tray can be placed at the bottom of the residue discharge chamber 12; when the residue is not needed, a trash can can be placed directly at the bottom of the residue discharge chamber 12.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
