Abstract
The utility model discloses a kind of circular arc type air-suction cover, comprise top flap, side board and coaming plate, described top flap and side board are mutually vertical to be arranged, top flap and side board both sides are surrounded the air-suction cover of a square by described coaming plate, and described top flap and side board junction are provided with the pore for being communicated with negative pressure system; The inner side air inlet face of described air-suction cover is the arc surface of indent, and overlap is provided with arc-shaped orifice plate and the steel wire of coupling on described arc surface.The utility model adopts circular arc type air-suction cover, under the prerequisite not affecting working space, that can try one's best produces dirt pits by air-suction cover near work, make the scope close to producing dirt pits minimum, and effectively can stop that the spark produced in the course of work is splashed in air-suction cover by steel wire and enter dust pelletizing system, avoid deduster on fire.
Description
Technical field
The utility model belongs to technical field of industrial dust removal, is specifically related to a kind of circular arc type air-suction cover for collecting flue dust.
Background technology
Current industrial dedusting air-suction cover aspirating atmospheric type used is broadly divided into: top is inhaled, side draught, top suction+side draught.Common top draft hood hangs on above workpiece, because be subject to the impact of operating space, top draft hood is wanted to stay enough required distance between workpiece, if the air quantity surplus of design is large not, a part of flue dust can be run away outside air-suction cover, causes efficiency of dust collection to reduce.On the other hand, common side-draught hood inhales with top+and side-draught hood considers that air quantity is balanced, capital adds one deck perforate web plate in air-breathing plane, although it is near relative to top draft hood that this air-suction cover distance produces dirt pits, but for some workpiece in irregular shape, also need to reserve enough working spaces, to prevent the spark splashed in flue dust from entering dust pelletizing system, cause potential safety hazard.It is infeasible that the air-suction cover of obvious use routine can produce pyrophoric place in grinding etc.
Utility model content
The technical problem that the utility model solves is: the collection existed for existing dedusting air-suction cover is with the flue dust poor effect of spark, cause the defect that working space is narrow and small, a kind of spark that can effectively stop with flue dust generation in the course of work is provided, the circular arc type air-suction cover of larger working space can be provided again to workman.
The utility model adopts following technical scheme to realize: a kind of circular arc type air-suction cover, comprise top flap 1, side board 2 and coaming plate 3, described top flap 1 and side board 2 vertical setting mutually, top flap 1 and side board 2 both sides are surrounded the air-suction cover of a square by described coaming plate 3, and described top flap 1 and side board 2 junction are provided with the pore 6 for being communicated with negative pressure system; The inner side air inlet face of described air-suction cover is the arc surface of indent, and overlap is provided with arc-shaped orifice plate 5 and the steel wire 4 of coupling on described arc surface.
Further, the mesh size of described steel wire 4 is less than the plate hole size that orifice plate 5 is offered.
Further, described top flap 1 is provided with knuckle with side board 2 end and is connected with orifice plate 5 and steel wire 4.
Further, described steel wire 4 is arranged on the outside of orifice plate 5.
Further, described orifice plate 5 and steel wire 4 for cross section be the circular arc camber of quadrant.
Be different from the method that existing air-suction cover collects flue dust, the utility model adopts circular arc type air-suction cover, under the prerequisite not affecting working space, that can try one's best produces dirt pits by air-suction cover near work, make the scope close to producing dirt pits minimum, and effectively can stop that the spark produced in the course of work is splashed in air-suction cover by steel wire and enter dust pelletizing system further, avoid deduster on fire.
From the above mentioned, a kind of circular arc type air-suction cover that the utility model provides, little and can effectively isolate the spark produced in the course of work close to producing the distance of dirt pits, to reach the object of effectively collecting flue dust, and safety coefficient is high.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.

Detailed description of the invention
Embodiment
In conjunction with the three-view diagram see circular arc type air-suction cover in Fig. 1, Fig. 2 and Fig. 4, comprise top flap 1, side board 2 and coaming plate 3, top flap 1 and side board 2 vertical setting mutually, top flap 1 and side board 2 both sides are surrounded the air-suction cover of a square by coaming plate 3, and top flap 1 and side board 2 junction are provided with the pore 6 for being communicated with negative pressure system; The inner side air inlet face of air-suction cover is the arc surface of indent, and overlap is provided with arc-shaped orifice plate 5 and the steel wire 4 of coupling on arc surface, as shown in Figures 2 and 3, the mesh size of steel wire 4 should be less than the plate hole size that orifice plate 5 is offered, and effectively interception is by the spark of orifice plate.Top flap 1 is provided with knuckle with side board 2 end and is connected with orifice plate 5 and steel wire 4.
Preferably, orifice plate 5 and steel wire 4 for cross section be the circular arc camber of quadrant, steel wire 4 should be stacked in the outside of orifice plate 5.
See Fig. 5, air-suction cover air inlet face is arranged to the arc surface of indent, in concrete production, under not affecting the prerequisite of operating space, can by the product dirt pits 7 near production of air-suction cover maximum magnitude, shorten the distance of flue dust collecting, adopt vertical top flap and side board to realize pushing up suction+side draught simultaneously simultaneously, improve flue dust collecting efficiency, simultaneously, before web plate, increase layer of steel wire net stop with the sudden spark of flue dust, realize air-suction cover minimum and effectively prevent spark close to the scope of producing dirt pits, avoid deduster on fire.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The utility model can not be restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
