Description

Technical Field

[0001] The utility model relates to the field of casting processing, in particular to a side suction cover structure used for casting processing. Background Art

[0002] The main casting process includes: metal smelting, model making, pouring solidification and demoulding cleaning, etc. The main materials used for casting are cast steel, cast iron, cast non-ferrous alloys (copper, aluminum, zinc, lead, etc.), etc. The metal casting process is to pour the molten metal into the pouring port of the casting mold, and then cool it to get the formed workpiece. The pouring process often requires the use of a gas collection hood to collect the fume and oil pollution generated by the pouring.

[0003] When the oily flue gas generated in the pouring process is collected by an air collecting hood, it is impossible to set a top suction air collecting hood directly above the equipment to collect the high-temperature flue gas due to working conditions. At the same time, the existing air collecting hood cannot cool the inhaled high-temperature flue gas, which causes the high-temperature flue gas to enter the pipeline and easily cause damage to the pipeline. For this reason, the present application proposes a side suction hood structure for pouring processing to solve the above problems. Utility Model Content

[0006] Preferably, the side suction cover body is an annular structure, and the cross-section of each guide plate is an arc-shaped structure.

[0007] Preferably, the heat exchange assembly comprises two connection blocks with one end fixedly mounted to the pipeline via a connection flange, and an intermediate cylinder is fixedly connected between the two connection blocks.

[0008] Preferably, a through groove communicating with the interior of the intermediate tube is formed at the center of each of the connecting blocks, and a plurality of heat exchange plates are penetrated and fixedly connected to the side wall of the intermediate tube.

[0010] Preferably, one end of each of the heat exchange plates is fixedly penetrated by the side wall of the intermediate tube and extends into the interior of the intermediate tube, and the other end of each of the heat exchange plates extends to the outside of the intermediate tube.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model arranges a side suction hood body on the top of the workbench, so as to collect the high-temperature smoke generated in the pouring process through multiple side suction ports opened on the inner side of the side suction hood body. Therefore, when the working conditions are limited and it is impossible to arrange a top suction type air collecting hood directly above the workbench, the high-temperature smoke is collected through the side suction hood body, and the high-temperature smoke sucked in the side suction hood body is discharged through the pipeline through the negative pressure environment generated by the negative pressure fan, and the multiple arc-shaped guide plates arranged in the side suction hood body are used for guiding the high-temperature smoke during the high-temperature smoke collection process. In order to avoid the high-temperature smoke In order to prevent the high-temperature flue gas from entering the pipeline and causing damage to the pipeline, a heat exchange component is arranged on one side of the pipeline, and one end of each connecting block is fixedly installed with one end of the pipeline on one side through a connecting flange, which is also convenient for disassembly and installation. An intermediate cylinder is arranged between the two connecting blocks, and multiple heat exchange plates are plugged and fixed through the inner wall of the intermediate cylinder. Therefore, the high-temperature flue gas enters the intermediate cylinder from the pipeline and exchanges heat with the heat exchange plate after contacting it, thereby realizing the cooling process of the high-temperature flue gas. The multiple heat exchange plates are staggered so that the high-temperature flue gas can contact the heat exchange plate more fully, thereby improving the cooling effect.
