Description

TECHNICAL FIELD

[0001] The utility model belongs to metallurgical production field, especially relates to the boiler flame monitoring cooling air filter device. BACKGROUND

[0002] The boiler flame detection camera is a device for monitoring and controlling the internal flame state of the boiler. It monitors the flame condition in real time to ensure the safety and stability of the boiler operation. The boiler flame detection camera can capture images and videos of the flame and determine the state of the flame through intelligent analysis technology, so as to take protective measures when necessary.

[0003] Because the boiler flame detection camera is in a high-temperature working environment, in order to ensure its long-term stable operation, a cooling system needs to be installed at the camera installation position to reduce the temperature of the camera itself and prevent damage or performance degradation due to overheating. The cooling method is usually to use a fan to deliver natural wind from the outside through a pipeline to the camera to continuously cool and cool the camera itself and the surrounding working environment. Although this method is simple, fast and low in cost, the fan is easy to suck impurities carried by the natural wind from the outside and blow them to the camera, causing the camera to accumulate dust seriously after long-term use, which not only affects its normal heat dissipation, thereby causing damage or performance degradation, but also the large particle impurities blown into the camera are easy to damage the camera, causing the interruption of the boiler flame detection system and increasing the risk of safe production.

DETAILED DESCRIPTION

[0015] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation mode of the utility model will be described by referring to the drawings:

[0016] For example, Figures 1 to 2As shown, the boiler flame monitoring cooling air filter device comprises a square air supply pipe 1, a filter box 2 is inserted in a socket formed in the top wall of the square air supply pipe 1, a through opening 3 is formed in each of the two side walls of the filter box 2, a first mounting hole 4 and a second mounting hole 5 are formed in the top wall of the filter box 2, an air filter screen 6 is inserted in the first mounting hole 4, an air filter fiber plate 7 is inserted in the second mounting hole 5, a first handle 8 is installed on the top wall of the filter box 2, a cap 9 is installed on the top end of the filter box 2, a first L-shaped buckle plate 10 matching the shape of the two end edges of the cap 9 is installed on the outer top wall of the square air supply pipe 1, and the two end edges of the cap 9 are inserted in the first L-shaped buckle plate 10; a second handle 16 is installed on the top end of the air filter screen 6 and the air filter fiber plate 7.

[0017] Specifically, the filter box 2 arranged in the square air supply pipe 1 can filter out impurities carried in the natural wind, so that clean natural wind is blown to the boiler flame monitoring camera.

[0018] In actual use, the left end of the square air supply pipe 1 is connected with an outdoor fan, and the right end of the square air supply pipe 1 is connected with the area of the boiler flame monitoring camera. When cooling, the external natural wind is blown from the left side of the square air supply pipe 1 to the filter box 2, and then contacts the air filter screen 6 through the left side through opening 3. At this time, the air filter screen 6 filters out larger particle impurities or dust carried in the natural wind. The initially filtered natural wind then contacts the air filter fiber plate 7. At this time, the air filter fiber plate 7 filters out smaller particle impurities or dust carried in the natural wind. The clean natural wind filtered through multiple layers is blown out from the right side through opening 3 and blown to the remote boiler flame monitoring camera area, so as to cool and lower the temperature of the camera and the surrounding environment. When cleaning the filter device, the protective cap 9 is quickly pulled out of the first L-shaped buckle plate 10, and the filter box 2 is pulled out of the square air supply pipe 1 by pulling the first handle 8. At this time, the air filter screen 6 and the air filter fiber plate 7 are pulled out by pulling the second handle 16, so as to clean or replace the new filter of the dust attached to the surface, thereby ensuring the normal operation of the air filter device.

[0019] As Figures 1 to 2As shown, the boiler flame monitoring cooling air filter device is provided with a sundry storage box 11 on the outer bottom wall of the square air supply pipe 1, a second L-shaped buckle plate 12 matching the shape of the two end edges of the sundry storage box 11 is installed on the outer bottom wall of the square air supply pipe 1, the two end edges of the sundry storage box 11 are inserted into the second L-shaped buckle plate 12, a sundry discharge port 13 is formed on the bottom wall of the square air supply pipe 1, the sundry discharge port 13 is communicated with the inner cavity of the sundry storage box 11, the sundry discharge port 13 is located on the windward side of the filter box 2, the bottom wall of the sundry storage box 11 corresponding to the directly below the sundry discharge port 13 is inclined downward, a first trapezoidal flow guide strip 14 and a second trapezoidal flow guide strip 15 are respectively installed on the inner top wall and the inner bottom wall of the square air supply pipe 1 along the width direction, and the second trapezoidal flow guide strip 15 is located on the outer side of the sundry discharge port 13.

[0020] Specifically, the sundry storage box 11 can temporarily store the large-particle sundries filtered out, so that the normal air supply volume of the square air supply pipe 1 is ensured.

[0021] In actual use, the large-particle sundries carried in the natural wind are filtered out by the air filter screen 6 and then fall into the sundry storage box 11 through the sundry discharge port 13 for temporary storage, when the sundries are cleaned, the sundry storage box 11 is pulled out from the second L-shaped buckle plate 12, the sundries are poured out, and then the sundry storage box 11 is inserted into the second L-shaped buckle plate 12 again, so that the quick installation and disassembly of the sundry storage box 11 are completed; the bottom wall of the sundry storage box 11 is inclined downward, so that the falling sundries can converge to the bottom end of the box, thereby further avoiding the blockage of the sundry discharge port 13 and maximizing the temporary storage of the sundries; the first trapezoidal flow guide strip 14 and the second trapezoidal flow guide strip 15 installed on the inner top wall and the inner bottom wall of the square air supply pipe 1 can further guide and converge the natural wind to the through port 3 of the filter box 2, thereby improving the air flow.
