[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.
[0015] like Figure 1 , Figure 2 As shown, a dust suction fire extinguishing device provided in this embodiment includes an air outlet joint 1, a spherical sleeve 2, an air inlet joint 3 for connecting compressed air, and a dust suction port joint 4 for sucking aluminum oxide dust.
[0016] The air outlet connector 1 comprises a first port 11 and a second port 12 which are arranged opposite to each other. The first port 11 is a bell mouth.
[0017] The spherical sleeve 2 is a purchased part, which is selected as a common spare part for aluminum ladle. The spherical sleeve 2 is provided with a first interface 21, a second interface 22 and a third interface 23, and a cavity 24 is provided inside the spherical sleeve 2. The cavity 24 is a spherical cavity. The first interface 21, the second interface 22 and the third interface 23 are connected with the cavity 24. The first interface 21, the second interface 22 and the third interface 23 are all threaded ports. The first interface 21 and the second interface 22 are located on the same horizontal line, and the third interface 23 is perpendicular to the line connecting the first interface 21 and the second interface 22.
[0018] The gas outlet joint 1 is threadedly connected to the first interface 21, and the first port 11 is located in the cavity 24 and communicates with the cavity 24, and the second port 12 is placed outside the spherical sleeve 2. When the gas outlet joint 1 is in use, the second port 12 thereon can discharge the aluminum oxide powder in the cavity 24 to achieve fire extinguishing.
[0019] The air inlet joint 3 is threadedly connected to the second interface 22, one end of the air inlet joint 3 extends into the cavity 24, and the other end is located outside the spherical sleeve 2, and a buckle 31 for fixing the air pipe is provided on the outside. The buckle 31 is a buckle structure, which can firmly fix the compressed air pipe on the air inlet joint 3. When the air inlet joint 3 is used, the compressed air is connected to provide power for dust collection through negative pressure. The first port 11 is arranged directly opposite the air inlet joint 3.
[0020] The dust suction port connector 4 is threadedly connected to the third interface 23. When the dust suction port connector 4 is used, the connecting pipe is used to absorb aluminum oxide dust to achieve limited dust removal.
[0021] The connection between the air outlet joint 1 and the spherical sleeve 2, between the air inlet joint 3 and the spherical sleeve 2, and between the dust suction port joint 4 and the spherical sleeve 2 needs to be sealed, and a sealing ring or other sealing structure can be used.
[0022] When in use, connect the dust suction port connector 4 to the dust suction pipe, and connect the air inlet connector 3 to the compressed air through the air pipe. Start the air compressor to generate negative pressure in the cavity 24, then align the dust suction pipe with the equipment that needs to be dusted, and suck the aluminum oxide dust on the equipment into the cavity 24 for collection, so as to achieve limited cleaning of the dust. In addition, the flow rate of compressed air can be increased or decreased by adjusting the opening size of the compressed air valve to achieve accelerated or decelerated dust suction function. When fire extinguishing is required, open the valve on the air outlet connector 1, start the air compressor to generate positive pressure, and quickly spray out the aluminum oxide dust collected in the cavity 24 to achieve fire extinguishing. The air compressor is selected as a single or two compressors with positive and negative pressure. If fire extinguishing is not required, directly disassemble the spherical sleeve 2 and dump the dust in the cavity 24 to a centralized treatment point.
