Abstract

The invention relates to a multifunctional casting weight capable of achieving dust collection and recovery. The multifunctional casting weight includes a weight body, and a through flue gas channel is formed in the weight body; the side face of the flue gas channel is connected with a side suction channel, and the bottom surface of the flue gas channel is connected to a top suction channel; a gasprocessing chamber is connected to the top of the flue gas channel, and the gas processing chamber is filled with a gas processing medium; a gas collection port is formed in the top of a gas outlet of the gas processing chamber; an air inlet of the top suction channel is formed in the bottom surface of the weight body; and an air inlet of the side suction channel is formed in the side face of theweight body. A casting site flue gas recovery method based on the casting weight is further included and comprises the steps that firstly, the flue gas channel is formed in the weight body; then theweight body is placed on a sand mold sand box in a casting mould closing state, and the air inlet of the flue gas channel corresponds to a pouring cup, a sand mold air hole and a casting riser in position; recovered flue gas is connected to an air inlet of flue gas centralized recovery processing equipment through a pipeline; and the centralized recovery processing equipment is provided with an air extraction device to form negative pressure in the flue gas channel.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, and is mainly aimed at the casting process part. [0002] During the pouring stage of the entire casting process, a large amount of smoke, VOC organic gas, and carbon monoxide will be generated. Especially in view of the increasingly stringent environmental protection requirements at the present stage, it has played a certain role in promoting the development of environmental protection technology in the entire foundry industry. And the invention is created in order to solve the gas collection problems such as smoke and dust produced when pouring in the existing foundry industry. Background technique [0003] At this stage, there is no national standard for the dust treatment in the pouring process in the foundry field, and the industry is also making active efforts to improve the environmental protection of foundry. [0004] At present, when the entire foundry industry handles the colle...
