Description
Technical field
This utility model belongs to cement manufacture plant technical field, and specifically, this utility model relates to a kind of cement packing
With the combination type air exhausting device unloading fortune area applications.
Background technology
At present, in cement packing operation process, owing to finished cement powder is thin, bagged cement it is difficult to ensure that do not reveal,
Therefore in unloading bag and course of conveying, the mobile of bagged cement can produce substantial amounts of airborne dust so that operator's building ring of upper bag
Border and neighbouring air ambient are heavily contaminated, affect personnel healthy, contaminated air.
The dustproof facilities in existing cement packing workshop includes unloading chartered plane exhaust hood A, bottom air draft point B and packer periphery
Enclosing C(is shown in accompanying drawing 1).Controlling of dust is main by unloading the local exhaust of air draft point B bottom chartered plane exhaust hood A and packer
Realize, control the dust produced in bag loading and unloading packet procedures.But owing to on-the-spot dust generating capacity is relatively big, fill in external wind and technique
Put on-the-spot dust-contained airflow tissue turbulence under thermolysis, and packer periphery enclosing C is the most relatively low, is only only capable of stopping packer material
The dust stream of mouth ejection, it is impossible to dust-contained airflow plays stronger effect of contraction, ultimately results in cement packing Work places and ventilates
Dust removing effects is the best.
Prior art has compared with the present invention that following some is not enough:
(1) considering that exhaust gas region operating distance is shorter, enclosing does not has the effect strengthening degassing function simultaneously, makes limited
Extraction flow can not play efficient dust and carry effect.
(2) although packaging area and the external world are isolation, but it is similar to a tunnel owing to unloading bag transporter, packed in transport
While cement, also form the connected channel of inside and outside air-flow, cause when extraneous blast is bigger, external air flow can be by unloading bag
Conveyer and the space that on it, exhaust hood is formed, directly charge into packer peripheral region, increase distributing of dust.
(3) owing to there is the phenomenon that dust inorganization distributes, and aerofluxus can not form unified effective air-flow, although existing
Needed for having technology, exhaust air rate is relatively big, but ventilating dust-removing effect is very poor, and package handling place dust exceeding is serious.
The Chinese utility model patent of Application No. CN201520402977.6, discloses a kind of bagged cement entrucking conveying
Machine dust collecting system, including fixing airduct, Telescopic air pipe, supports airduct, dust collection cover, dustproof shade；Described fixing airduct is arranged on
Above the framework of conveyer standing part；Described Telescopic air pipe is sleeved on fixing airduct and with the telescopic section of conveyer even
Connect, it is possible to move relative to fixing airduct；Described support airduct is arranged on dust collection cover, and its inner chamber is with dust collection cover inner chamber even
Logical, the other end of support airduct is connected with fixing airduct and inner chamber communicates；Described dust collection cover is arranged on support airduct, in it
Chamber is more than the bagged cement outlet of conveyer；Described dustproof shade is arranged on the lower section of dust collection cover and removes the another of conveyor outlet one side
Outer three sides；But this utility model only address only the dust emission problem at entrucking position, can not be to packaging position
Dust and air-flow play effect of contraction.
