Description

Technical Field

[0001] This utility model relates to the field of building material testing technology, and in particular to a device for testing the fire resistance performance of building materials. Background Technology

[0002] Fire performance testing of building materials is a process of assessing the combustion characteristics and fire resistance of materials under fire conditions. This testing is crucial for ensuring the fire safety of buildings because it can help select appropriate building materials, slow the spread of fire, buy valuable time for evacuation and firefighting, and thus reduce casualties and property losses caused by fire.

[0003] Traditional fire performance testing devices for building materials mostly lack filtration structures, making it difficult to effectively handle the smoke and harmful gases generated during combustion testing. If these gases are directly released into the air, they will impact the environment and affect the health of workers. Therefore, we propose a fire performance testing device for building materials. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fire resistance performance testing device for building materials.

[0005] This utility model is achieved using the following technical solution: a fire resistance performance testing device for building materials, comprising a testing box, a door hinged to the front end of the testing box, an observation window fixedly connected to the inner wall of the door, an electric push rod fixedly connected to the top of the testing box, the output end of the electric push rod penetrating the testing box and fixedly connected to a flame gun, a connecting pipe connected to the rear end of the flame gun, a gas cylinder provided at the rear end of the testing box, a filter assembly provided at the left end of the testing box, a placement plate fixedly connected to the inner wall of the testing box, and a collection box slidably connected to the inner wall of the testing box;

[0006] The filtration assembly includes a filter box, an installation bracket fixedly connected to the inner wall of the filter box, an exhaust fan fixedly connected to one end of the installation bracket, a filter screen slidably connected to the inner wall of the filter box, an activated carbon filter screen slidably connected to the inner wall of the filter box, a fixing plate provided on the top of the filter box, a handle fixedly connected to the top of the fixing plate, and a filter box opening at the left end of the filter box.

[0007] The above technical solution uses an exhaust fan to draw harmful gases from the testing chamber into the filter chamber. Larger particles in the smoke are removed by the filter screen, and then the harmful gases and odors are adsorbed by the activated carbon filter. Finally, the gases are discharged through the vent, protecting the environment and the health of the staff. When cleaning the filter screen and activated carbon filter is required, the handle is pulled to move the fixing plate upwards, allowing the filter screen and activated carbon filter to be removed from the filter chamber, facilitating subsequent cleaning and maintenance and improving practicality.

[0008] As a further improvement to the above solution, the right end of the filter box is fixedly connected to the left end of the detection box, and the filter box and the detection box are in communication with each other.

[0009] Through the above technical solution, since the filter box is connected to the detection box, the harmful gases and smoke generated during combustion can enter the interior of the filter box.

[0010] As a further improvement to the above solution, the exhaust fan is located between the filter screen and the activated carbon filter screen.

[0011] As a further improvement to the above solution, the bottom of the fixing plate is fixedly connected to the top of the filter screen and the activated carbon filter screen.

[0012] With the above technical solution, when the fixing plate moves upward, it will drive the filter screen and activated carbon filter screen to move upward simultaneously, which facilitates subsequent disassembly.

[0013] As a further improvement to the above solution, the end of the connecting pipe away from the flame gun is connected to the gas cylinder, and the placement plate is located at the upper end of the collection box.

[0014] The above technical solution allows the gas inside the gas tank to be transported to the inside of the flame gun via a connecting pipe.

[0015] As a further improvement to the above solution, the inner wall of the placement plate is provided with a through groove, and a hydraulic rod is fixedly connected to the rear end of the detection box.

[0016] The above technical solution allows the combustion residue to fall into the collection box through the through-channel, and the collection box collects the residue for subsequent unified treatment.

[0017] As a further improvement to the above solution, the output end of the hydraulic rod passes through the detection box and is fixedly connected to a scraper, the lower surface of which contacts the upper surface of the placement plate.

[0018] The above technical solution involves activating a hydraulic rod, whose output end drives a scraper to move, thereby scraping away the residue from the upper surface of the plate after combustion.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention incorporates a filtration system. Specifically, a fan draws harmful gases from inside the detection chamber into the filter chamber. Larger particles in the smoke are removed by a filter screen, and then activated carbon absorbs the harmful gases and odors before they are expelled through an outlet. This protects the environment and the health of workers. When cleaning the filter screen and activated carbon filter is required, the handle is pulled to move the fixing plate upwards, allowing the filter screen and activated carbon filter to be removed from the filter chamber. This facilitates subsequent cleaning and maintenance, improving practicality.

[0021] This utility model incorporates a collection box, a scraper, and a hydraulic rod. Specifically, by activating the hydraulic rod, the output end of the hydraulic rod pushes the scraper to move, scraping away the residue from the surface of the plate after combustion. The residue then falls through a channel into the collection box, avoiding manual cleaning and improving ease of use. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5This embodiment of a fire resistance performance testing device for building materials includes a testing box 1. A door 2 is hinged to the front end of the testing box 1. An observation window 3 is fixedly connected to the inner wall of the door 2. An electric push rod 4 is fixedly connected to the top of the testing box 1. The output end of the electric push rod 4 passes through the testing box 1 and is fixedly connected to a flame gun 5. A connecting pipe 6 is connected to the rear end of the flame gun 5. A gas tank 7 is provided at the rear end of the testing box 1. A filter assembly 8 is provided at the left end of the testing box 1. A placement plate 9 is fixedly connected to the inner wall of the testing box 1. A collection box 11 is slidably connected to the inner wall of the testing box 1.

[0032] The filter assembly 8 includes a filter box 801. A mounting bracket 802 is fixedly connected to the inner wall of the filter box 801. An exhaust fan 803 is fixedly connected to one end of the mounting bracket 802. A filter screen 804 and an activated carbon filter screen 805 are slidably connected to the inner wall of the filter box 801. A fixing plate 806 is provided on the top of the filter box 801, and a handle 807 is fixedly connected to the top of the fixing plate 806. The filter box 801 is located on the left end. During combustion, the building materials will produce harmful gases and smoke, triggering the exhaust fan. 803 allows harmful gases inside the detection chamber 1 to enter the filter chamber 801. Larger particles in the smoke are removed by the filter screen 804, and then harmful gases and odors are adsorbed by the activated carbon filter screen 805. Finally, the gases are discharged outward through the air outlet 808, protecting the environment and the health of the staff. When it is necessary to clean the filter screen 804 and the activated carbon filter screen 805, pull the handle 807 to move the fixing plate 806 upward, and remove the filter screen 804 and the activated carbon filter screen 805 from the inside of the filter chamber 801 for easy subsequent cleaning and maintenance, thus improving practicality.

[0033] The right end of the filter box 801 is fixedly connected to the left end of the detection box 1, and the filter box 801 and the detection box 1 are interconnected.

[0034] The exhaust fan 803 is located between the filter screen 804 and the activated carbon filter screen 805.

[0035] The bottom of the fixing plate 806 is fixedly connected to the top of the filter screen 804 and the activated carbon filter screen 805.

[0036] The end of the connecting pipe 6 away from the flame gun 5 is connected to the gas canister 7, and the placement plate 9 is located at the top of the collection box 11.

[0037] The inner wall of the placement plate 9 is provided with a through groove 10, and the rear end of the detection box 1 is fixedly connected with a hydraulic rod 13.

[0038] The output end of the hydraulic rod 13 passes through the detection box 1 and is fixedly connected to a scraper 12. The lower surface of the scraper 12 contacts the upper surface of the placement plate 9. When the hydraulic rod 13 is activated, the output end of the hydraulic rod 13 pushes the scraper 12 to move. The scraper 12 scrapes off the residue after combustion on the upper surface of the placement plate 9 and drops it into the collection box 11 through the through groove 10, avoiding manual cleaning and improving the convenience of use.

[0039] The implementation principle of the fire resistance performance testing device for building materials in this embodiment is as follows: During use, the door 2 is opened, and the building materials are placed on the placement plate 9. Gas from the gas cylinder 7 is supplied to the flame gun 5 via the connecting pipe 6, igniting the flame gun 5. The flame gun 5 then performs a combustion test on the building materials. The electric push rod 4 is activated, and its output pushes the flame gun 5 downwards. The distance between the flame gun 5 and the building materials can be adjusted as needed. During combustion, the building materials produce harmful gases and smoke. The exhaust fan 803 is activated, allowing the harmful gases inside the testing chamber 1 to enter the filter chamber 801. Larger particles in the smoke are removed through the filter screen 804. Harmful gases and odors are then adsorbed by the activated carbon filter 805 and discharged through the air outlet 808, protecting the environment and the health of the staff. After the test is completed, the hydraulic rod 13 is activated, and the output end of the hydraulic rod 13 pushes the scraper 12 to move. The scraper 12 scrapes off the residue after combustion on the upper surface of the placement plate 9 and drops it into the collection box 11 through the through groove 10, avoiding manual cleaning and improving the convenience of use. When it is necessary to clean the filter 804 and the activated carbon filter 805, the handle 807 is pulled to move the fixing plate 806 upward, and the filter 804 and the activated carbon filter 805 are removed from the inside of the filter box 801, which is convenient for subsequent cleaning and maintenance and improves practicality.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
