wherein: 1, core box exhaust pipe; 2, core box die joint bleeding point; 3, exhaust gas processing device; 4, workbench; 5, lowering or hoisting gear; 6, core box die joint exhaust pipe; 7, pneumatic air door; 8, equipment screen; 9, air blowing shield; 10, triethylamine catalysis gas air inlet; 11, core; 12, core box.
Detailed description of the invention
below in conjunction with drawings and Examples, the invention will be further described:
the tail gas collecting device of a kind of core making machine as shown in Figure 1, 2, this device comprises core box vacuum elements, core box die joint vacuum elements, exhaust gas processing device 3 and electric-control system, specifically:
core box vacuum elements comprises the first bleeding point be opened on core box dolly, be opened in the second bleeding point on workbench 4 and core box exhaust pipe 1, and the second bleeding point is connected with exhaust gas processing device 3 by core box exhaust pipe 1.Workbench 4 is connected with lowering or hoisting gear 5, lowering or hoisting gear 5 can be oil cylinder, cylinder etc.; When core box vacuum elements is bled, lowering or hoisting gear 5 rises, and the first bleeding point, the second bleeding point fit tightly mutually; When core box dolly moves, lowering or hoisting gear 5 declines, and there is gap between the first bleeding point, the second bleeding point.Lower core box offers bleeding point, core box dolly offers the first bleeding point, in general, lower core box is arranged on core box dolly, and the bleeding point on lower core box and the first bleeding point on core box dolly align.When core box shifting trolley exists movable, just require to there is gap between the first bleeding point, the second bleeding point, otherwise the operation of core box shifting trolley can be affected; When core box vacuum elements is bled, if there is this gap, the seal that core box is bled is just poor, therefore in the present embodiment, by arranging lowering or hoisting gear 5, can meet motion and can ensure seal again, solving the high efficiency that core box is bled.
core box die joint vacuum elements comprises at least one the core box die joint bleeding point 2, the core box die joint exhaust pipe 6 that are arranged on core box die joint place, and core box die joint bleeding point 2 is connected with exhaust gas processing device 3 by core box die joint exhaust pipe 6.Core box die joint vacuum elements effectively can be collected and produce the core box on die joint and the residual gas in core.
consider that core box vacuum elements is different from the time period of core box die joint vacuum elements air-extraction function, this device arranges two exhaust gas processing device interfaces, connect core box exhaust pipe 1 and core box die joint exhaust pipe 6 respectively, by installing pneumatic air door 7 additional on these two independent pipelines, pass through electric-control system, the opening and closing of programme-control two pipeline, when core making machine carries out core box air blowing, core box vacuum elements path; When core box die joint opened by core making machine, core box die joint vacuum elements path.The combination of this pattern, can control the exhausting amount of exhaust gas processing device further, can solve the occupation of land problem of exhaust gas processing device, can solve energy consumption problem again, the most important thing is due to exhaust collection targetedly, and vent gas treatment is efficient, reliable.
for triethylamine cold core process core making machine, what exhaust gas processing device 3 was mainly collected is core solidification triethylamine residual gas, by in conjunction with aerogenerator of triethylamine air-blowing quantity hourly, adjust exhaust gas processing device exhausting amount hourly, in airtight situation, the residual gas in core box and core is remained in when also will consider core box parting, by the data in conjunction with these two aspects, final exhaust gas processing device exhausting amount can be drawn, these exhausting amount data are only 1/7 ~ 1/10 of exhaust gas processing device exhausting amount under prior art, the minimizing of exhaust gas processing device exhausting amount reduces the volume of device on the one hand, decrease energy consumption.
in addition, the face that the second bleeding point place offered by the core box dolly face of offering the first bleeding point place and workbench is that inclined-plane coordinates, i.e. inclined-plane sealing; The face that the first bleeding point place offered by core box dolly is consistent with the direction of motion of the direction that the face that the second bleeding point place offered by workbench is offered and core box dolly, vertical plane coordinates, namely direction of motion sealing realizes the seal of the first bleeding point, the second bleeding point, or employing directly connects exhausting flexible pipe road on core box.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
