Description

Technical Field

[0001] This utility model relates to the technical field of combustion performance testing, specifically a device for testing the combustion performance of thermal insulation building materials. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that meet people's needs for production, residence, study, and public activities. To ensure the quality of buildings, thermal insulation materials undergo combustion testing to ensure that problems will not occur after construction. Currently, most thermal insulation material combustion performance testing devices use a burner mounted on a cylinder. Depending on the size or thickness of the insulation material, the cylinder pushes the burner close to the material to ignite it. This ignition method suffers from uneven combustion and slow combustion speed, and the ash mostly remains inside the chamber, making cleaning difficult. Therefore, we provide a thermal insulation material combustion performance testing device to solve these problems. Utility Model Content

[0003] To address the aforementioned problems, specifically those raised in the background section, this utility model proposes a device for testing the combustion performance of thermal insulation building materials. The device includes a housing with a perforated plate horizontally arranged within its inner cavity. A detection head is positioned above the perforated plate. A fan is installed on the top of the housing. A flamethrower is mounted on the side wall of the housing. A connecting pipe is fixedly installed at the output end of the flamethrower. Several branch pipes are connected to the other end of the connecting pipe, and nozzles are fixedly installed at the ends of the branch pipes. The nozzles movably penetrate the inner cavity of the perforated plate and are arranged in a circular array around the perforated plate.

[0004] Preferably, a door is installed at the discharge port of the box, and several air inlet pipes are provided through the side wall of the box. The air inlet pipes are distributed at equal intervals, and the exhaust end of the air inlet pipe is located close to the perforated plate.

[0005] Preferably, the top of the orifice plate is provided with a plurality of support blocks, the top of the support blocks is spherical, and a tripod is fixedly provided on the outer wall of the detection head, the tripod being fixedly provided on the inner wall of the housing.

[0006] Preferably, the output end of the blower is connected to a filter tube, which is installed through the top of the housing. The inner cavity of the filter tube is provided with an activated carbon filter plate and a sponge filter pad from the inside to the outside. The input end of the blower is fixedly provided with a gas collection hood.

[0007] Preferably, a push plate is attached to the center of the bottom of the inner cavity of the box, and a cylinder is connected to the side of the push plate away from the material discharge port of the box. The cylinder is fixedly installed in the inner cavity of the box, and an inclined plate is fixedly installed above the cylinder in the inner cavity of the box. The end of the inclined plate near the push plate is lower than the other end, and the cylinder can drive the push plate to retract only below the inclined plate.

[0008] The beneficial technical effects of this utility model are as follows: by setting up connecting pipes and branch pipes, the flame can be set below the thermal insulation building material for ignition, and it presents a multi-point uniform combustion from bottom to top, which makes it have the characteristics of uniform combustion, fast combustion speed, and accurate test results.

[0009] By setting a support block on the top of the perforated plate, a certain cavity can be created at the bottom of the thermal insulation material, ensuring sufficient oxygen supply to the combustion point of the thermal insulation material and preventing the material from going out due to lack of oxygen during combustion.

[0010] The inclined plate at the bottom of the box can completely move the ash between the push plate and the door. Under the action of the cylinder, the push plate can be pushed to move the ash to the bottom of the inner cavity of the box, realizing the collection of ash. This replaces the traditional manual ash removal and has certain practicality.

[0011] By installing a gas collection hood at the inlet of the fan, the absorption area of ​​the flue gas can be increased, and the dust inside the gas can be filtered out by the filter tube, so that the gas can be directly discharged into the atmosphere, reducing air pollution.

[0016] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] This utility model proposes a device for testing the combustion performance of thermal insulation building materials, including a box body 1.

A detection head 3 is provided above the perforated plate 2 for testing the thermal insulation building materials after combustion. A fan 5 is provided on the top of the box body 1 to draw smoke out of the box body 1. A flamethrower 4 is installed on the side wall of the box body 1. The flamethrower 4 can ignite the thermal insulation building materials. A connecting pipe 41 is fixedly provided at the output end of the flamethrower 4. The other end of the connecting pipe 41 is connected to several branch pipes 42. A nozzle 43 is fixedly provided at the end of the branch pipe 42. The nozzles 43 are movably inserted through the inner cavity of the perforated plate 2 and arranged in a ring array with the perforated plate 2 as the center. The connection pipe 41 and the branch pipes 42 can be arranged so that the flame is positioned below the thermal insulation building materials for ignition and presents a multi-point uniform combustion from bottom to top, which has the characteristics of uniform combustion, fast combustion speed, and accurate test results.

[0018] Specifically, a door 11 is installed at the discharge port of the box 1, which can close the box 1. Several air inlet pipes 7 are installed through the side wall of the box 1. The air inlet pipes 7 are evenly distributed, and the exhaust end of the air inlet pipes 7 is located close to the perforated plate 2. The air inlet pipes 7 can provide oxygen for the combustion of thermal insulation building materials.

[0019] Specifically, the top of the perforated plate 2 is provided with several support blocks 21, the top of which is spherical. By providing support blocks 21 on the top of the perforated plate 2, the bottom of the insulation material can have a certain cavity, so that the combustion point of the insulation material can have sufficient oxygen supply, avoiding the phenomenon of extinguishing due to lack of oxygen during combustion. The outer wall of the detection head 3 is fixedly provided with a tripod 31, which is fixedly provided on the inner wall of the box 1. Through the design of the tripod 31, the detection head 3 can be placed in the center position when the insulation material is tested, which is convenient for testing.

[0020] Specifically, the output end of the fan 5 is connected to a filter pipe 51, which is installed through the top of the housing 1. The inner cavity of the filter pipe 51 is provided with an activated carbon filter plate and a sponge filter pad from the inside to the outside. The input end of the fan 5 is fixedly provided with a gas collection hood 52. By setting the gas collection hood 52 at the input end of the fan 5, the absorption area of ​​the flue gas can be increased, and under the filtration of the filter pipe 51, the dust inside the gas can be filtered, so that the gas can be directly discharged into the atmosphere, reducing air pollution.

[0021] Specifically, a push plate 8 is attached to the center of the bottom of the inner cavity of the box 1. A cylinder 81 is connected to the side of the push plate 8 away from the discharge port of the box 1. The cylinder 81 is fixedly installed in the inner cavity of the box 1. An inclined plate 6 is fixedly installed above the cylinder 81 in the inner cavity of the box 1. The end of the inclined plate 6 near the push plate 8 is lower than the other end. The cylinder 81 can drive the push plate 8 to retract to the bottom of the inclined plate 6. The inclined plate 6 at the bottom of the box 1 can completely move the ash between the push plate 8 and the door 11. Under the action of the cylinder 81, the push plate 8 can be pushed to move the ash to the bottom of the inner cavity of the box 1, realizing the collection of ash.

[0022] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0023] Working principle: First, open the door 11 and place the insulation material at the center of the top of the support block 21 above the carrier plate. Then, close the door 11 and start the flamethrower 4 and the fan 5. The flamethrower 4 can supply gas and spray flames to several branch pipes 42 through the connecting pipe 41. Several nozzles 43 simultaneously spray flames onto the insulation material, which can achieve uniform combustion at multiple points, increase the combustion speed, and obtain more accurate test results under uniform combustion. During combustion, the fan 5 can absorb the smoke through the gas collection hood 52, while the air inlet pipe 7 can supply gas to the insulation material. Oxygen is supplied inside the chamber 1. The flue gas enters the filter pipe 51 through the fan 5 for filtration. The filtered gas is discharged into the atmosphere. The ash from the combustion of the thermal insulation building materials falls to the bottom of the inner cavity of the chamber 1 through several holes in the perforated plate 2. The inclined plate 6 moves all the ash between the door panel and the push plate 8. After the combustion is completed, the door 11 can be opened. Under the action of the cylinder 81, the push plate 8 can be pushed to push the ash out of the inner cavity of the chamber 1, replacing the traditional manual cleaning method. The operation is simple and convenient.
