preferably, on described workbench, be connected with lowering or hoisting gear, when described core box, bleed assembly while bleeding, described lowering or hoisting gear rises, and described the first bleeding point, the second bleeding point fit tightly mutually; When described core box dolly moves, described lowering or hoisting gear declines, and between the first described bleeding point, the second bleeding point, has gap.
preferably, the face that described core box dolly is offered the first described bleeding point place is that inclined-plane coordinates with the face at the second bleeding point place described in described workbench is offered.
preferably, the face that described core box dolly is offered the first described bleeding point place is that vertical plane coordinates with the face at the second bleeding point place described in described workbench is offered.
preferably, described core box exhaust pipe, core box die joint exhaust pipe are connected with described tail gas collecting device respectively, and are respectively arranged with pneumatic air door.
because technique scheme is used, the utility model compared with prior art has following advantages:
the utility model adopts that core box is bled, core box die joint is bled, and adds the airtight design to core box exhaust pipe, and application program controlling bleed position utilizes the exhausting ability of exhaust gas processing device to greatest extent, makes its exhausting amount little, and energy consumption is low, effective.
Accompanying drawing explanation
accompanying drawing 1 is looked schematic diagram for master of the present utility model;
accompanying drawing 2 is schematic side view of the present utility model.
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
below in conjunction with drawings and Examples, the utility model is 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 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 core box dolly, is opened in the second bleeding point and core box exhaust pipe 1 on workbench 4, and core box exhaust pipe 1 is connected the second bleeding point with exhaust gas processing device 3.On workbench 4, be connected with lowering or hoisting gear 5, lowering or hoisting gear 5 can be oil cylinder, cylinder etc.; When core box is bled assembly while bleeding, 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 between the first bleeding point, the second bleeding point, has gap.On lower core box, offer bleeding point, offer the first bleeding point on core box dolly, 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 existence moves forward and backward, just require to have gap between the first bleeding point, the second bleeding point, otherwise can affect the operation of core box shifting trolley; When core box, bleed assembly while bleeding, 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 meets 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 die joint and the residual gas in 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 install pneumatic air door 7 additional on these two independent pipelines, pass through electric-control system, the switching of programme-control two pipelines, when core making machine carries out core box while blowing, the core box assembly path of bleeding; When core making machine is opened core box die joint, the core box die joint assembly path of bleeding.The combination of this pattern, can further control the exhausting amount of exhaust gas processing device, can solve the occupation of land problem of exhaust gas processing device, can solve energy consumption problem again, the most important thing is that vent gas treatment is efficient, reliable due to exhaust collection targetedly.
for triethylamine cold core process core making machine, what exhaust gas processing device 3 was mainly collected is the curing triethylamine residual gas of using of core, by in conjunction with aerogenerator of triethylamine air-blowing quantity hourly, adjust exhaust gas processing device exhausting amount hourly, in airtight situation, in the time of also will considering core box parting, remain in the residual gas in core box and core, by the data in conjunction with this two aspect, can draw final exhaust gas processing device exhausting amount, these exhausting amount data be only under 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, also reduced energy consumption.
in addition, it is that inclined-plane coordinates that core box dolly is offered the face that the face at the first bleeding point place offers the second bleeding point place with workbench, i.e. inclined-plane sealing; It is consistent that the face that 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 coordinates, be the seal that the direction of motion seals to realize the first bleeding point, the second bleeding point, or employing directly connect exhausting flexible pipe road on core box.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
