Accompanying drawing 2 is schematic side view of the present invention.
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.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
The tail gas collecting device of a kind of core making machine as shown in Figure 1, 2, this device comprise core box bleed assembly, core box die joint bleed assembly, exhaust gas processing device 3 and electric-control system, specifically:
The core box assembly of bleeding comprises the first bleeding point of being opened on the core box dolly, is opened in the second bleeding point and core box exhaust pipe 1 on the workbench 4, and core box exhaust pipe 1 is connected the second bleeding point with exhaust gas processing device 3.Be connected with lowering or hoisting gear 5 on the workbench 4, lowering or hoisting gear 5 can be oil cylinder, cylinder etc.; When core box is bled assembly when bleeding, lowering or hoisting gear 5 rises, and the first bleeding point, the second bleeding point fit tightly mutually; When the core box dolly moved, lowering or hoisting gear 5 descended, and has the gap between the first bleeding point, the second bleeding point.Offer bleeding point on the lower core box, offer the first bleeding point on the core box dolly, in general, lower core box is installed on the core box dolly, and the bleeding point on the lower core box and the first bleeding point on the core box dolly align.When the core box shifting trolley existence moves forward and backward, just require to have the gap between the first bleeding point, the second bleeding point, otherwise can affect the operation of core box shifting trolley; Bleed assembly when bleeding when core box, if there is this gap, the seal that core box is bled is just poor, therefore in the present embodiment, by lowering or hoisting gear 5 is set, can satisfies motion and can guarantee seal again, has solved the high efficiency that core box is bled.
The core box die joint assembly of bleeding comprises at least one core box die joint bleeding point 2, the core box die joint exhaust pipe 6 that is arranged on core box die joint place, and core box die joint exhaust pipe 6 is connected core box die joint bleeding point 2 with exhaust gas processing device 3.The core box die joint assembly of bleeding can effectively be collected the core box that is created on the die joint and the residual gas in the core.
Consider that core box bleed time period of assembly air-extraction function of assembly and core box die joint of bleeding is different, this device arranges two exhaust gas processing device interfaces, connect respectively core box exhaust pipe 1 and core box die joint exhaust pipe 6, by installing pneumatic air door 7 additional at these two independent pipelines, pass through electric-control system, the switching of programme-control two pipelines, when core making machine carries out core box when blowing, the core box assembly path of bleeding; When core making machine is opened the core box die joint, the core box die joint assembly path of bleeding.The exhausting amount of exhaust gas processing device can be further controlled in the combination of this pattern, can solve the occupation of land problem of exhaust gas processing device, can solve energy consumption problem again, the most important thing is that because exhaust collection targetedly, 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 curing 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, also to consider to remain in when core box divides mould the residual gas in core box and the core, by the data in conjunction with this two aspect, can draw final exhaust gas processing device exhausting amount, these exhausting amount data only be under the prior art exhaust gas processing device exhausting amount 1/7～1/10, the minimizing of exhaust gas processing device exhausting amount has reduced the volume of device on the one hand, has also reduced energy consumption.
In addition, the face that the core box dolly is offered the first bleeding point place is that the inclined-plane cooperates with the face that workbench is offered the second bleeding point place, i.e. inclined-plane sealing; It is consistent that the face that the core box dolly is offered the first bleeding point place and workbench are offered the direction of motion of direction that the face at the second bleeding point place offers and core box dolly, vertical plane cooperates, be the seal that the direction of motion seals to realize the first bleeding point, the second bleeding point, perhaps adopt directly to connect exhausting flexible pipe road at core box.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
