Abstract
The utility model provides a furan resin sand gas collection device, the sand outlet of roller mill aircraft nose is fixed with harmful gas through the flange and purifies filtering mechanism, and harmful gas purifies filtering mechanism including collecting cover, observation window, filler opening, ventilative mesh board, active carbon, and collects the outside processing of cover and have observation window and filler opening, and collects the cover inside and placed ventilative mesh board, and the active carbon is put on ventilative mesh board, it is provided with the exhaust hole and is connected with hose one end to collect cover head, and the hose other end is connected with the dust remover and constitutes the negative pressure suction. This technical scheme passes through harmful gas purification filtering mechanism, improves the purifying effect to harmful gas, and the gas after the purification can directly discharge to the air in, and difficult polluted environment can not cause the injury to the human body.
Description
Technical Field
The utility model relates to a gas collecting device, specially adapted furan resin sand casting technology.
Background
In the casting process, sand mixing of core sand is basically carried out by a sand mixer, binders used in the sand mixing process are furan resin and benzenesulfonic acid curing agents, in the sand mixing process, pungent odor of formaldehyde can be generated, the gas can cause physical injury to field workers, the original treatment mode is air suction emission, the mode cannot achieve purification of the gas, and the discharged gas cannot meet the requirement of environmental protection.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a harmful gaseous pollutants just can discharge after purifying, and the gaseous furan resin sand gas collection device that can reach the environmental protection requirement of emission.
The utility model discloses a task is accomplished like this, its characterized in that: the sand outlet of sand mixer head is fixed with harmful gas purification and filtration mechanism through the flange, and harmful gas purification and filtration mechanism has observation window and filler opening, ventilative mesh board, active carbon including collecting cover, observation window, filler opening, just collects the outside processing of cover, and collects the inside ventilative mesh board of having placed of cover, and active carbon is put on ventilative mesh board, it is provided with the exhaust hole and is connected with hose one end to collect the cover head, and the hose other end is connected with the dust remover and constitutes the negative pressure suction. The filler opening processed outside the collecting cover is butt-jointed with a filler hopper and hinged with the collecting cover through a hinge, and the active carbon is filled through the filler hopper. The air-permeable mesh plate is of a drawing type. The hose is fixed on a rotating arm of the sand mixer head.
The utility model discloses has following effect: this technical scheme passes through harmful gas purification filtering mechanism, improves the purifying effect to harmful gas, and the gas after the purification can directly discharge to the air in, and difficult polluted environment can not cause the injury to the human body.
Drawings
Fig. 1 is a schematic structural diagram of the present invention; FIG. 2 is a side view of FIG. 1; fig. 3 is a sectional view of the internal structure of the collecting cover.
Description of the drawings: 1. the device comprises a collecting cover, 2, an observation window, 3, a sand mixer head 4, a hinge key, 5, a filling opening, 6, a breathable mesh plate, 7, activated carbon, 8, a hose, 9 and a dust remover.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
As shown in the specific embodiment, in order to ensure that the adopted binder furan resin does not pollute the working environment when the sand mixer works, the gas collecting device related to the technical scheme does not occupy space when being installed.
The sand outlet of the sand mixer head 3 is fixed with a harmful gas purification filter through a flange and winds, the harmful gas purification filter mechanism comprises a collection cover 1, an observation window 2, a filling opening 5, a breathable mesh plate 6 and active carbon 7, the collection cover is externally processed with the observation window 2 and the filling opening 5, the collection cover is internally provided with the breathable mesh plate 6, the active carbon 7 is placed on the breathable mesh plate, the head of the collection cover is provided with an exhaust hole and is connected with one end of a hose 8, and the other end of the hose 8 is connected with a dust remover 9 to form negative pressure suction.
The filler opening processed outside the collecting cover is butt-jointed with a filler hopper and hinged with the collecting cover through a hinge 4, and the active carbon is filled through the filler hopper.
The air-permeable mesh plate 6 is of a drawing type, and is convenient to clean.
The hose 8 is fixed on a rotating arm of the sand mixer head, and does not occupy space.
During operation, this device has collection cover 1, observation window 2, hinge 4, filler opening 5, ventilative mesh board 6, activated carbon 7 several parts are constituteed, it is connected with dust remover 9 through coupling hose 8 to collect cover 1 top, in sand mixer work sand outlet process, form the negative pressure suction in collecting cover 1 through coupling hose 8 by dust remover 9, the sucking is by the pungent nature gas that produces in sand outlet department furan resin reaction process, after gas passes through ventilative mesh board 6, there is activated carbon 7 of this top to adsorb in the activated carbon to harmful gas, thereby reduce harmful gas's diffusion, ensure safety. The using condition of the activated carbon is observed through the observation window 2 and the filling port 5 periodically, and the activated carbon 7 is replaced to ensure normal work. Improve the working environment of workers.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
