Description

Technical Field

[0001] This utility model relates to the field of fire-retardant coating technology, and more specifically, to a flame-retardant performance testing device for decorative fire-retardant coatings. Background Technology

[0002] Fire-retardant coatings are special coatings that delay the spread of fire through mechanisms such as flame retardancy, heat insulation, and carbonization expansion. They are widely used in construction, power, transportation and other fields. Their core components include flame retardants, film-forming resins and fire-resistant fillers. When exposed to fire, they can form a dense char layer that isolates oxygen and heat. Based on their characteristics, they can be divided into intumescent and non-intumescent types (high-temperature resistant inorganic coatings). They have both decorative and protective functions. Modern fire-retardant coatings have developed towards environmental protection, with low-VOC and water-based products becoming the trend.

[0003] During performance testing of decorative fire-retardant coatings, operators often use corresponding flame-retardant testing devices to conduct flame-retardant tests. However, while existing testing devices have basic testing functions, a significant amount of combustion residue tends to accumulate at the bottom of the device after testing, making it difficult to clean. Furthermore, the accumulation of residue can affect subsequent test results. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a flame retardant performance testing device for decorative fireproof coatings, which has the advantage of being easy to clean up combustion residues.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a flame retardant performance testing device for decorative fireproof coatings, including a housing 1. A first motor 2 is fixedly connected to the back of the housing 1. A first rotating shaft 3 is fixedly sleeved at the other end of the output shaft of the first motor 2. A rotating plate 4 is fixedly sleeved at the other end of the first rotating shaft 3. Sleeve rods 5 are movably connected to both the left and right sides of the outer surface of the rotating plate 4. A connecting rod 6 is fixedly connected to the outer side of the sleeve rod 5. The other end of the connecting rod 6 passes through the housing 1 and extends into the interior of the housing 1 and is fixedly connected to a push plate 7. The outer surface of the push plate 7 is movably connected to the inner surface of the housing 1.

[0023] When the first motor 2 is turned on, the first rotating shaft 3 will drive the rotating plate 4 to rotate, which will cause the sleeve rod 5 to squeeze and push the two connecting rods 6. The two connecting rods 6 will drive the two push plates 7 to move horizontally towards each other under the limiting action of the outer shell 1, and finally realize the function of collecting the combustion residue scattered at the bottom of the inner cavity of the outer shell 1.

[0024] The outer casing 1 has a hinged sealing plate 8 on its front side, and an observation window 9 is fixedly connected to the front side of the sealing plate 8. An igniter 12 is fixedly sleeved inside the left side of the outer casing 1.

[0025] This design allows operators to observe the flame-retardant properties of the fire-retardant coating through the observation window 9 and decide when to activate or deactivate the igniter 12.

[0026] The outer shell 1 has a fixed rod 10 fixedly connected to both the left and right sides of the inner cavity, and a placement platform 11 fixedly connected to the other end of the fixed rod 10. A collection box 25 is movably connected to the bottom of the outer shell 1, and a second filter screen 26 is threadedly connected to the left side of the outer shell 1.

[0027] The decorative fire-retardant coating will be placed on top of the placement platform 11. When the igniter 12 is turned on, the decorative fire-retardant coating will be ignited.

[0028] The outer casing 1 has a connecting tube 13 fixedly sleeved inside the right side, and a filter box 14 is fixedly connected to the other end of the connecting tube 13. A first filter screen 15 is movably connected inside the filter box 14, and a second clamping plate 24 is movably connected to the right side of the first filter screen 15. The second clamping plate 24 is fixedly installed inside the filter box 14.

[0029] When the decorative fire-retardant coating starts to burn, the harmful gases produced by the combustion will enter the interior of the filter box 14 through the connecting pipe 13, and will be discharged after being filtered by the first filter screen 15.

[0030] The filter box 14 has a fixed tube 16 inside the left side, and a fan 17 is fixedly connected to the left side of the fixed tube 16. The fan 17 is fixedly installed on the right side of the outer casing 1, and an installation tube 18 is fixedly connected to the left side of the fan 17.

[0031] When the fan 17 starts running, it will draw air from the inner cavity of the outer casing 1 through the fixed pipe 16 and finally discharge the filtered air through the installation pipe 18.

[0032] The filter box 14 has a second motor 19 fixedly installed on its right side, and the other end of the output shaft of the second motor 19 is fixedly connected to a second rotating shaft 20.

[0033] When the second motor 19 starts running, it will cause the second rotating shaft 20 to rotate.

[0034] The other end of the second rotating shaft 20 passes through the filter box 14 and extends into the interior of the filter box 14, and is fixedly sleeved with a rotating plate 21. The other end of the rotating plate 21 is hinged with a diagonal rod 22, and the other end of the diagonal rod 22 is hinged with a first clamping plate 23. The outer surface of the first clamping plate 23 is movably connected to the left side of the first filter screen 15 and the inner surface of the filter box 14, respectively.

[0035] When the second rotating shaft 20 rotates, the rotating plate 21 will start to rotate as well, and the inclined rod 22 will move, eventually causing the first clamping plate 23 to move to the left, thereby releasing the fixing effect on the first filter screen 15.

[0036] Working principle and usage process of this utility model:

[0037] First, rotate and open the sealing plate 8, and put in the decorative fire-retardant coating to be tested. Then, turn on the igniter 12 to ignite it and observe and record the relevant data. At this time, start the fan 17, which will draw out the harmful gases produced by combustion in the inner cavity of the outer shell 1 through the connecting pipe 13. After being filtered by the connecting pipe 13 and the first filter screen 15, the gases are discharged from the device through the installation pipe 18. After the test is completed, start the first motor 2, which will cause the first rotating shaft 3 to drive the rotating plate 4 to rotate. This will cause the sleeve rod 5 to squeeze and push the two connecting rods 6, so that the two connecting rods 6 will drive the two push plates 7 to move horizontally in opposite directions under the limiting action of the outer shell 1. Finally, the combustion residue at the bottom of the inner cavity of the outer shell 1 will be pushed into the collection box 25, realizing the centralized collection function of combustion residue and avoiding the accumulation of residue that will affect subsequent test operations.

[0038] When filter screen 15 needs to be replaced after long-term use, starting the second motor 19 will cause the second rotating shaft 20 to drive the rotating plate 21 to rotate, thereby causing the inclined rod 22 to move. At this time, under the limiting action of the filter box 14, the first clamping plate 23 will move horizontally to the left, thereby releasing the fixing effect on filter screen 15, realizing the function of easy replacement of filter screen 15, improving the efficiency of operators in replacing filter screen 15, and reducing the labor intensity of operators.
