Abstract
The invention discloses a screen device. The screen device comprises a shell adapted with the shape of a sand core, wherein the shell is provided with a plurality of tail gas treatment interfaces. When the screen device is used, the sand core is sealed in the shell, then triethylamine is introduced into the shell to harden the sand core, the triethylamine for hardening the sand core can be discharged outwards through the tail gas treatment interfaces on the shell, and corresponding gas collecting devices are arranged on the tail gas treatment interfaces to collect the triethylamine; therefore, the triethylamine can be effectively prevented from being directly discharged to the atmosphere to pollute the air.
Description
Technical field
The present invention relates to the casting and molding technical field, particularly a kind of screen device that in the core hardening process, uses.
Background technology
At present in foundry production, in order to improve the efficient of casting, cold-box core blower manufacturing is adopted in the moulding of core more, after the core manufacturing is finished, in order to prevent the core distortion, usually need harden to core, at present be to use triethylamine to make the core sclerosis to the core method commonly used of hardening, generally be to feed triethylamine to make the core sclerosis on core.But in this process, often having a large amount of triethylamine tail gas reveals, triethylamine is a kind of toxic gas of alkalescence, can pollute environment on every side if directly be discharged in the air, therefore triethylamine need be put together and handle, could discharge in air after waiting to reach the discharging national standard, therefore just needing a special device like this can fence up core, triethylamine can not disperseed very much, so that the collection of triethylamine.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provides a kind of screen device that uses that is specifically designed in the core hardening process.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of screen device, it comprises a housing that adapts with the core shape, described housing is provided with several vent gas treatment interfaces.
Preferably, described vent gas treatment interface is positioned at the top of described housing.
Preferably, being provided with installation in the described housing supports.
Preferably, described housing is provided with observation window.
Technique scheme has following beneficial effect: this screen device in use, core is sealed in the housing, feeding triethylamine then in housing hardens to core, triethylamine after core hardened can discharge by the vent gas treatment interface on housing, corresponding gas collector is installed on the vent gas treatment interface to be collected triethylamine, so just can effectively avoid triethylamine directly to be discharged in the atmosphere, avoid the triethylamine contaminated air.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. describe in detail as after.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, this screen device comprises a housing 1 that adapts with the core shape, and the top of housing 1 is provided with several vent gas treatment interfaces 2.In housing 1, be provided with to install and support 3, on housing 1, also be provided with observation window 4.
This screen device in use, core is sealed in the housing 1, install to support 3 with core to contacting, make core 3 fixed-site, feeding triethylamine then in housing 1 hardens to core, triethylamine after core hardened can discharge by vent gas treatment interface 2 on housing, and vent gas treatment interface 2 is positioned at the top of housing, and triethylamine is fully contacted with core.Corresponding gas collector is installed on the vent gas treatment interface triethylamine is collected, so just can effectively avoid triethylamine directly to be discharged in the atmosphere, avoid the triethylamine contaminated air.
More than a kind of screen device that the embodiment of the invention provided is described in detail; for one of ordinary skill in the art; thought according to the embodiment of the invention; part in specific embodiments and applications all can change; in sum; this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
