Abstract
The utility model provides a technical scheme of an environmental protection screen. The scheme mainly comprises a riddling exit, a plus mesh exit, a screen box which comprises screen surfaces, and a feeder, characterized in that a dust absorption flue which comprises a dust absorption flue upper plate and a dust absorption flue lower plate is arranged below the feeder and the screen box, the bottom portion of the dust absorption flue is communicated with a space below the inner screen surface of the screen box, the upper portion of the dust absorption flue upper plate is provided with a dust absorption port which is communicated with a space below the upper screen surface of the screen box, a dust-exhausting port is equipped on the dust absorption flue lower plate, and the dust-exhausting port is equipped on the upper portion of the dust absorption flue lower plate. Further, an athodyd combustion chamber is equipped outside of the dust absorption flue lower plate, and the dust-exhausting port is arranged in the athodyd combustion chamber. The wind suction in the athodyd combustion chamber is connected with the dust absorption flue through the dust-exhausting port, and then the dust absorption flue can have suction, thereby the dust absorption flue can absorb dust on the main dust-produced positions when a vibrating screen works. Further, the wind suction sucks below the sifting materials, thereby greatly reducing flying dust resulting from sifting materials, and improving the dust collection effect.
Description
Affiliated technical field:
The utility model relates to the vibratory sieve that is used to sieve material industrial, especially a kind of Environmentally friendly screen that alleviates the screening dust.
Background technology:
In the prior art, in order to alleviate the dust that vibratory sieve is produced when working, general employing is installed a dust flue additional at the end face of screen box, utilizes the suction of dust flue, and the dust in the screen box is siphoned away, and reaches the purpose of dedusting.Though this structure can play certain dust removing effects, the airborne dust that the screening material can be caused siphons away, but the dust that vibratory sieve caused mainly is to be created in below the compass screen surface, the dust that the dust flue on screening material top is difficult to screening material bottom to be produced siphons away, so the effect of this measure dedusting is undesirable.
Summary of the invention:
The utility model is at the existing in prior technology deficiency, and a kind of Environmentally friendly screen technical scheme that produces the key link increase dust collection capacity of dust at vibratory sieve is provided.
This programme is realized by following technical measures: mainly include screen box and the dispenser be made up of screening outlet, oversize outlet and compass screen surface, the characteristics of this programme are below described dispenser and screen box, the dust-absorbing flue that is made of dust-absorbing flue upper plate and dust-absorbing flue lower plate is arranged, space in the bottom of this dust-absorbing flue and the screen box under the compass screen surface communicates, there is suction port to communicate on the top of dust-absorbing flue upper plate, on the dust-absorbing flue lower plate, dust-exhausting port arranged with space under the compass screen surface of screen box top.The concrete characteristics of this programme also have, and described dust-exhausting port is the top in the dust-absorbing flue lower plate.Also have wind sucting chamber outside described dust-absorbing flue lower plate, described dust-exhausting port is just in wind sucting chamber.
According to as can be known to the narration of such scheme, since in this scheme below dispenser and screen box, the dust-absorbing flue that is made of dust-absorbing flue upper plate and dust-absorbing flue lower plate is arranged, space in the bottom of this dust-absorbing flue and the screen box under the compass screen surface communicates, there is suction port to communicate with space under the compass screen surface of screen box top on the top of dust-absorbing flue upper plate, dust-exhausting port also is housed on the dust-absorbing flue lower plate, also has wind sucting chamber outside the dust-absorbing flue lower plate, described dust-exhausting port is just in wind sucting chamber.This structure, air draught in the wind sucting chamber, link to each other with dust-absorbing flue by dust-exhausting port and to make dust-absorbing flue have suction, and dust-absorbing flue communicates with compass screen surface lower space in the screen box, dust-absorbing flue communicates with space under the compass screen surface of screen box top by suction port again simultaneously, when this just can work vibratory sieve, the dust that cause at the main position that produces dust siphons away, and the efficient of dedusting is improved, again because air draught is suction below the screening material, this can alleviate the screening airborne dust that material caused greatly, in addition, the dust that dust-absorbing flue sucks enters wind sucting chamber through dust-exhausting port, and dust can sedimentation in wind sucting chamber, and accumulate in the wind sucting chamber, also be convenient to remove.This shows that dust removing effects of the present utility model is splendid, so compared with prior art, have substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure schematic diagram of the utility model specific embodiment.
1 is screening outlet among the figure, and 2 are the oversize outlet, and 3 is screen box, and 4 is compass screen surface, and 5 is the dust-absorbing flue upper plate, and 6 is the dust-absorbing flue lower plate, and 7 is suction port, and 8 is dispenser, and 9 is dust-exhausting port, and 10 is wind sucting chamber, and 11 is dust-absorbing flue.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the Environmentally friendly screen of this programme, mainly include by screening outlet (1), screen box (3) and dispenser (8) that oversize outlet (2) and compass screen surface (4) are formed, the characteristics of this programme are below described dispenser (8) and screen box (3), the dust-absorbing flue (11) that is made of dust-absorbing flue upper plate (5) and dust-absorbing flue lower plate (6) is arranged, the bottom of this dust-absorbing flue (11) communicates with space under the interior compass screen surface of screen box (3) (4), there is suction port (7) to communicate with space under screen box (3) the top compass screen surface (4) on the top of dust-absorbing flue upper plate (5), dust-exhausting port (9) is arranged on dust-absorbing flue lower plate (6), and this dust-exhausting port (9) is the top in dust-absorbing flue lower plate (6).Also have wind sucting chamber (10) outside described dust-absorbing flue lower plate (6), described dust-exhausting port (9) is just in wind sucting chamber (10).
Claims (3)
1. Environmentally friendly screen, mainly include screen box and the dispenser formed by screening outlet, oversize outlet and compass screen surface, it is characterized in that: below described dispenser and screen box, the dust-absorbing flue that is made of dust-absorbing flue upper plate and dust-absorbing flue lower plate is arranged, space in the bottom of this dust-absorbing flue and the screen box under the compass screen surface communicates, there is suction port to communicate on the top of dust-absorbing flue upper plate, on the dust-absorbing flue lower plate, dust-exhausting port arranged with space under the compass screen surface of screen box top.
