Description

Technical Field

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

[0002] Fire resistance testing is mainly used to determine the fire resistance rating and fire-resistant structure of fire-resistant building materials, so as to better understand and differentiate the fire resistance performance of fire-resistant building materials.

[0003] Chinese patent document CN217033795U discloses a fire resistance testing device for fire-resistant building materials, belonging to the field of fire-resistant building testing. The device includes a mounting frame with an insulated box fixed to the top. Air inlet slots are formed on the left and right sides of the insulated box. Limiting blocks are fixed at the four corners of the inner wall of the insulated box. A mesh is installed inside the insulated box, with two handles fixed to the top of the mesh in a symmetrical arrangement. Exhaust slots are formed on the left and right sides of the insulated box. An igniter is fixed to the bottom of the inner wall of the insulated box, with an air inlet pipe fixed to the bottom of the igniter. A suction fan is fixed to the back of the insulated box, with two suction pipes fixed to the front of the suction fan in a symmetrical arrangement. By installing the suction fan, it can absorb smoke and dust inside the insulated box through the suction pipes, preventing smoke and dust from spreading to the outside of the insulated box and causing harm to the body.

[0004] The aforementioned existing technology has the following problems:

[0005] The detection device directly uses an air pump to extract gas from the insulated box. However, this method may cause smoke, flames, etc. to affect the air pump, leading to problems such as the air pump getting stuck due to dust or the high temperature gas affecting the lifespan of the air pump. Utility Model Content

[0006] This invention provides a fire resistance testing device for fire-resistant materials to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A fire resistance testing device for fireproof materials includes a base, a mechanism box connected to the upper side of the base by screws, ventilation holes opened on the left and right sides of the mechanism box near the bottom, a cover movably fitted on the inner side of the mechanism box near the upper side, an exhaust mechanism fixed with screws on the outer side of the mechanism box near the upper side, and an ignition mechanism movably installed on the inner side of the upper wall of the base.

[0009] The exhaust mechanism includes an air pump, and a vent pipe is detachably installed on the rear side of the air pump. Two air blowing pipes are fixed to the left and right sides of the mechanism box near the upper side by screws. The rear side of the vent pipe is snapped together with the front side of the air blowing pipe.

[0010] Preferably, both of the air-blowing pipes are threaded with guide tubes on their outer sides near the rear side.

[0011] Preferably, both air-blowing pipes are provided with heat insulation sleeves on their inner sides.

[0012] Preferably, a cooling tube is fixedly sleeved on the inner side of each of the two guide tubes, and the outer side of the cooling tube is welded to the inner side wall of the guide tube near both ends.

[0013] Preferably, a first filter screen is fixed to the front side of the air pump by screws, and a second filter screen is threaded to the rear side of both guide tubes.

[0014] Preferably, two filter plates distributed on the left and right sides are movably sleeved in the inclined grooves on the front and rear sides of the inner side of the mechanism box, close to the left and right sides.

[0015] Preferably, both cooling tubes have spacers movably fitted onto their inner sides.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This utility model utilizes the cooperation of an air pump, a ventilation pipe, a blowing pipe, a guide pipe, and a cooling pipe. By blowing air through the air pump, the air pressure at the opening on the side of the blowing pipe decreases as the gas passes through it. This causes the smoke and dust generated by the mechanism box to be automatically drawn in, avoiding the direct extraction method that would cause heat and smoke to affect the air pump.

[0018] At the same time, the first and second filters isolate the smoke and dust from the inside and outside, and the septum adsorbs the smoke and dust that enters the blowing pipe, thus avoiding the impact of the emitted gas. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1:

[0027] like Figures 1-5 As shown, this embodiment provides a fire resistance testing device for fireproof materials, including a base 1. A mechanism box 2 is connected to the upper side of the base 1 by screws. Ventilation holes 3 are opened on the left and right sides of the mechanism box 2 near the bottom. A cover 4 is movably sleeved on the inner side of the mechanism box 2 near the upper side. An exhaust mechanism 5 is fixed with screws on the outer side of the mechanism box 2 near the upper side. An ignition mechanism 6 is movably installed on the inner side of the upper wall of the base 1.

[0028] The exhaust mechanism 5 includes an air pump 51, and an air pipe 52 is detachably installed on the rear side of the air pump 51. Two air blowing pipes 53 are fixed to the left and right sides of the mechanism box 2 near the upper side by screws. The rear side of the air pipe 52 is snapped together with the front side of the air blowing pipe 53.

[0029] It should be noted that the structural design of the ignition mechanism 6 and the mechanism box 2 is consistent with that of the components with the same function in the reference case. The cover 4 and the mechanism box 2 are directly fixed together by quick-release buckles. The air pump 51 blows air into the air pipe 53, so that the airflow passes through the inside of the air pipe 53 from front to back, so that the air pipe 53 is in a negative pressure state relative to the mechanism box 2. This allows the smoke and dust generated in the mechanism box 2 to be automatically sucked into the air pipe 53, avoiding the impact of smoke and heat on the air pump 51 caused by the air extraction method.

[0030] like Figure 3 As shown, guide tubes 54 are threadedly connected to the outer sides of both air blowing pipes 53 near the rear. The guide tubes 54 guide the gas blown from the rear of the air blowing pipes 53, preventing it from blowing directly backward and affecting surrounding personnel. The threaded connection also allows for quick separation of the guide tubes 54 and air blowing pipes 53, facilitating maintenance of both.

[0031] like Figure 3 As shown, both air blowing pipes 53 are equipped with heat insulation sleeves on their inner sides. This heat insulation sleeves prevent the heat of the gas entering the air blowing pipe 53 from the mechanism box 2 from being conducted to the outer wall of the air blowing pipe 53, which would cause the air blowing pipe 53 to heat up and affect the operator's operation.

[0032] Example 2:

[0033] The only difference between this embodiment and Embodiment 1 is that, Figure 5 As shown, cooling tubes 55 are fixedly sleeved on the inner side of both guide tubes 54, and the outer side of the cooling tubes 55 is welded to the inner side of the side wall of the guide tubes 54 near both ends.

[0034] Therefore, the portion of the cooling pipe 55 located inside the air blowing pipe 53 is in the shape of a spiral tube. Cold water is injected from one end of the cooling pipe 55 and, after passing through the interior of the cooling pipe 55, cools the gas inside the air blowing pipe 53, thus preventing the directly ejected gas from affecting the surrounding working environment.

[0035] Furthermore, such as Figure 3 , Figure 4 As shown, the front side of the air pump 51 is fixed with a first filter screen 56 by screws, and the rear side of the two guide tubes 54 is fixed with a second filter screen 57 by threads.

[0036] The first filter 56 is used to prevent external dust from entering the air pump 51 and affecting its operation, while the second filter 57 is used to prevent the smoke and dust in the ejected gas from being directly discharged into the surrounding environment.

[0037] Meanwhile, two filter plates 58 are movably sleeved in the inclined grooves on the front and rear sides of the inner side of the mechanism box 2, which are close to the left and right sides. The filter plates 58 are used to protect the air blowing pipe 53 and prevent flames from entering the air blowing pipe 53. At the same time, the inclined groove shape allows the filter plates 58 to be quickly disassembled and assembled, which is convenient for maintenance of the filter plates 58.

[0038] Example 3:

[0039] The only difference between this embodiment and embodiment 1 or 2 is that, Figure 5 As shown, spacers 59 are movably sleeved on the inner side of both cooling tubes 55.

[0040] The spacer 59 is made of porous material and its two ends are sealed, so that the spacer 59 can adsorb the smoke and dust entering the air pipe 53 as much as possible, avoiding the problem that it is difficult to filter the smoke and dust for a long time if only the second filter screen 57 is used to block the smoke and dust.

[0041] The working principle of this utility model is as follows:

[0042] First, the air pump 51 blows air into the air blowing pipe 53, causing the airflow to pass through the inside of the air blowing pipe 53 from front to back. This creates a negative pressure state inside the air blowing pipe 53 relative to the mechanism housing 2, automatically drawing the smoke and dust generated inside the mechanism housing 2 into the air blowing pipe 53. This avoids the smoke and heat from the extraction method affecting the air pump 51. The guide pipe 54 guides the air blown out from the rear of the air blowing pipe 53, preventing it from blowing directly backward and affecting surrounding personnel. The threaded connection allows for quick separation of the guide pipe 54 and the air blowing pipe 53 for easy maintenance. The air pump 51 blows air, causing a pressure drop at the opening on the side of the air blowing pipe 53 as the air passes through it, thus reducing the pressure inside the mechanism housing. The generated smoke and dust are automatically sucked in, avoiding direct extraction which would affect the air pump 51 due to heat and smoke. Finally, the first filter 56 is used to prevent external dust from entering the air pump 51 and affecting its operation. The second filter 57 is used to prevent the smoke and dust in the ejected gas from being directly discharged into the surrounding environment. The septum 59 is made of porous material and its two ends are sealed, so that the septum 59 can adsorb the smoke and dust entering the blowing pipe 53 as much as possible. This avoids the problem that it is difficult to filter the smoke and dust for a long time if only the second filter 57 is used to block the smoke and dust. By isolating the smoke and dust inside and outside through the first filter 56 and the second filter 57, and then relying on the septum 59 to adsorb the smoke and dust entering the blowing pipe 53, the problem of the emitted gas affecting the air pump 51 is avoided.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
