Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Examples
A novel welding smoke dust suction hood comprises a first main suction cylinder 1, an apron board 2, a wind catching cover 3, a second main suction cylinder 4 and a main dust removal wind catching plate 5 from top to bottom in sequence; the first main air suction cylinder 1 is a hollow circular tube and is used for being connected with a dust removal pipeline through a hoop; the apron plate 2 is a rectangular plate, a circular through hole A is formed in the center of the apron plate 2, the diameter of the circular through hole A is equal to the outer diameter of the first main air suction cylinder 1, the circular through hole A of the apron plate 2 is coaxial with the first main air suction cylinder 1, and the lower end of the first main air suction cylinder 1 is welded with the apron plate 2 in a sealing mode; the wind catching cover 3 is a ladder platform shell with a cavity without a top, the shape size of the upper end of the wind catching cover 3 is larger than that of the lower end of the wind catching cover 3, the top end of the wind catching cover 3 is hermetically welded with the lower plate surface of the apron plate 2, a circular through hole B is formed in the center of the bottom surface of the wind catching cover 3 and is coaxial with the circular through hole A of the apron plate 2, a plurality of wind catching through holes B are densely formed in the bottom surface and the side wall of the wind catching cover 3, and the diameter of each wind catching through hole B is far smaller than that of; the second main air suction cylinder 4 is a cavity circular truncated cone shell without a top and a bottom, the diameter of the upper opening end of the second main air suction cylinder 4 is larger than that of the lower opening end, the diameter of the top of the second main air suction cylinder 4 is equivalent to that of the circular through hole B of the air catching cover 3, the second main air suction cylinder 4 is coaxial with the circular through hole B of the air catching cover 3, and the top of the second main air suction cylinder 4 is hermetically welded with the lower plate surface of the air catching cover 3; the main dust-removing wind-catching plate 5 is welded at the bottom end of the second main air suction barrel 4, and a plurality of wind-catching through holes A are densely arranged on the main dust-removing wind-catching plate 5.
Due to the combined arrangement of the apron board 2 and the wind catching cover 3, the capture range of welding smoke dust is enlarged, but the wind pressure at the main dust removal wind catching plate 5 is not greatly reduced; the arrangement of the second main air suction cylinder 4 ensures that the dust removal air pressure at the welding point is not greatly weakened; the second main air suction cylinder 4 in the shape of a circular truncated cone enables a higher-pressure air flow to be kept at a welding point; the arrangement of the plurality of wind catching holes on the main dust removing wind catching plate 5 ensures that the wind flow with higher pressure can be kept while the larger dust removing area of the welding point is ensured.
Use of this example: the main dust removal wind-catching plate 5 is placed above the welding point, and a plurality of wind-catching through holes A in the main dust removal wind-catching plate 5 are close to the welding point, and the wind pressure at the wind-catching through holes A is large, so that most of welding smoke dust can be captured; the cutting smoke dust overflowing from the wind catching through holes A rises along with the airflow and spreads to the lower part or the side part of the wind catching hood 3, and the wind catching through holes B on the bottom surface and the side wall of the wind catching hood 3 can catch most of the overflowing cutting smoke dust, so that the aim of further purification is fulfilled.
