Embodiment Construction

[0014] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the present invention provides a full mold casting flue gas treatment device, which is used for flue gas treatment in the full mold casting process. The device comprises an air extraction cover box 1, and the shape of the air extraction cover box 1 is not limited. Here, a cube is used as an example to describe in detail. The bottom of the air extraction cover box 1 is open, and the four sides and the top are integrated. During use, the air extraction cover box 1 is covered on the solidified mold, mainly covering the open riser and the air outlet.

[0016] The top of the air extraction cover box 1 is connected with at least one air extraction pipe 2, preferably two, and here are two air extraction pipes 2 as an example for specific description, the air extraction pipe 2 is connected with the exhaust fan 3 respectivel...

Abstract

The invention relates to the technical field of full mold casting, in particular to a full mold casting smoke treatment device. The device comprises an exhaust cover box; the top of the exhaust cover box is connected with at least one exhaust pipe; the exhaust pipes are respectively connected with an exhaust fan; and a first metal filter screen, a refractory cotton layer, a refractory ceramic filter layer and a second metal filter screen are arranged in the exhaust cover box in sequence from top to bottom. The exhaust pipes are respectively provided with exhaust filter cylinders; and first refractory cotton layers, active carbon layers, second refractory cotton layers and third refractory cotton layers are arranged in the exhaust filter cylinder in an exhaust flowing direction. The first metal filter screen, the refractory cotton layer, the refractory ceramic filter layer and the second metal filter screen are arranged in the exhaust cover box in sequence from top to bottom for absorbing smoke and dust generated in the full mold casting process to optimize the workshop environment, so that the health of operators is effectively guaranteed, and meanwhile, the environment is protected.

Description

technical field [0001] The invention relates to the technical field of full mold casting, in particular to a full mold casting flue gas treatment device, which includes a suction cover box. Background technique [0002] The full mold casting adopts the polystyrene foamed plastic pattern instead of the ordinary wooden mold. After the mold is made, the mold is not taken out, and the molten metal is directly poured into it. Under the action of ordinary molten metal, the plastic pattern burns, vaporizes, and disappears. The molten metal replaces the space occupied by the original plastic film, and the required casting is obtained after cooling and solidification. Full mold casting has obvious advantages, simplifies the production process, reduces the cost of castings, shortens the production cycle, and improves the precision of castings. However, during the pouring process, the full mold casting produces a large amount of black smoke with high temperature and high concentration...
