Abstract
The inventions belong to the field of material transfer operations, in particular to a dust suppression device of a blanking tube for a bulk material station. The dust suppression device of the blanking tube for the bulk material station is characterized in that a dust collection cover is communicated with an energy dissipation separator, the energy dissipation separator is communicated with a dust collection draught fan, the dust collection draught fan is communicated with the middle portion of the blanking tube, and an opening of the dust collection cover is correspondingly arranged above the dust raising position. Compared with the existing dust removal technology, the dust suppression device of the blanking tube for the bulk material station has the advantages of active dust suppression and prevention and being capable of completely treat dust pollution in operations effectively, accelerating the elimination of dust and haze and protecting the environment effectively.
Description
Technical field
The invention belongs to material transfer operation field, relates to material dust collector, specifically a kind of bulk cargo transfer point material blanking tube dust-arrest device.
Background technology
The positions such as transfer point at bulk conveying systems such as raw coal, breeze, owing to being mingled with the bulk cargo of air, when dropping to bottom, piles up transfer point material blanking tube, formed dirt pits, the air of wherein carrying secretly is by violent shear extrusion, and the tiny grit carrying in bulk cargo is diffused into surrounding space from the separation of bulk cargo high speed, cause serious dust pollution.
Administer various cargo handling operations, the dust pollution to air, to alleviate dust haze to the having a strong impact on of weather, is when the environmental protection subject of forward swing in face of people.
Summary of the invention
Contriver is in being engaged in for many years the transhipment operation process of relevant bulk material; observe bulk cargo when dropping to bottom; can produce dirt pits; the dust of kicking up causes gross pollution to surrounding space, also there is no to find the effectively technical measures of improvement at present, through exploring; object is to develop a kind of bulk cargo transfer point material blanking tube dust-arrest device; can apply, effectively solve the dirt that bulk drop material produces, better protection of the environment.
The technical scheme that the invention is taked is a kind of bulk cargo transfer point material blanking tube dust-arrest device of design, its structure comprises: frame, bulk cargo material blanking tube, in frame, be provided with dust shield, energy dissipating disconnector, dust absorption fan, wherein dust shield is communicated with the dust inlet of energy dissipating disconnector by sweep-up pipe, the entrance of dust absorption fan is communicated with the air outlet of energy dissipating disconnector, in dust absorption fan outlet, be provided with backwind tube, dust shield cover mouth correspondence is arranged on rising above dirt pits of bulk cargo material blanking tube bottom side, and the outlet of dust absorption fan is communicated with the middle part of bulk cargo material blanking tube by backwind tube.
This bulk cargo transfer point material blanking tube dust-arrest device of the invention, adopt abovementioned technology, according to bulk material dynamically, bulk cargo is in the process of the inner whereabouts of transfer point material blanking tube, be mingled with part air and carrying it and accelerate, when bulk cargo is being mingled with air, drop to material blanking tube when bottom, bulk cargo has formed dirt pits owing to piling up shear action, forces its air being mingled with carrying fine particle in bulk cargo space high speed diffusion towards periphery.Under the effect of dust absorption fan, the dust shield that is arranged in a dirt pits top, material blanking tube bottom aspirates dusty gas to enter sweep-up pipe fast, and sends into energy dissipating disconnector and carry out kinetic energy energy dissipating and travel fatigue separation to playing dirt.
Energy dissipating disconnector is improved existing cyclone, cavity volume by cylindric change into round table-like, or other shape.
Dust laden air is at a high speed collected into after energy dissipating disconnector, laterally dilatation in energy dissipating disconnector, thereby and form eddy current and effectively consume its kinetic energy, make it no longer have an energy of oriented space diffusion, under the centrifugation of disconnector, larger particles reaches effective separated recovery, isolated dust is collected in energy dissipating disconnector dust mouth and adds bulk cargo transporting groove to carry, dust laden air after energy dissipating enters dust absorption fan from energy dissipating disconnector air outlet, and supplement and enter in material blanking tube by backwind tube, form closed loop.
The closed loop that this device forms, because the dust absorption fan in device has made to form enough negative pressure near dirt pits, can fast this part kinetic energy gas collection be entered to energy dissipating disconnector, thereby avoid near the excessive of the high velocity air of dirt pits, this device plays negative pressure dust suppression effect.
Because the dust laden air in closed loop contains larger particles and fine particle two parts, wherein larger dust is forced to energy dissipating separation in energy dissipating disconnector, falls into energy dissipating disconnector bottom and reclaims, and this device plays energy dissipating dust suppression effect.
Because in closed loop, compared with fine particle, the separation efficiency in energy dissipating disconnector is very low, still continuation circulation under the carrying of air of major part.But fine particle can reach capacity very soon in the air of C/LOOP state, the cycle air energy after saturated effectively stops material blanking tube bottom to play further dissolving in of the newborn dust of dirt pits, thereby plays saturated dust suppression effect.
Model machine, through trial-production and at thread test, shows safe in operation, reliable and stable, functional, and dust suppression dust-proof effect is desirable.
This bulk cargo transfer point material blanking tube dust-arrest device of the present invention; compare with existing dedusting technology; changed traditional passive dedusting; by negative pressure dust suppression, energy dissipating dust suppression, saturated dust suppression, combine; there is initiatively dust suppression dustproof; can effectively effect a radical cure the dust pollution that cargo handling operation brings, accelerate to eliminate dust haze weather, the remarkable advantage of strong protection of the environment.
Accompanying drawing explanation
Fig. 1 represents the overall structure schematic diagram of the invention bulk cargo transfer point material blanking tube dust-arrest device.
The specific embodiment
In conjunction with the accompanying drawings and embodiments, further illustrate concrete structure and the mounting means of the invention.
The embodiment of the invention bulk cargo transfer point material blanking tube dust-arrest device, referring to Fig. 1, its structure comprises: frame 1, bulk cargo material blanking tube 8, in frame 1, be provided with dust shield 2, energy dissipating disconnector 6, dust absorption fan 5, wherein dust shield 2 is communicated with the dust inlet of energy dissipating disconnector 6 by sweep-up pipe 3, the entrance of dust absorption fan 5 is communicated with the air outlet of energy dissipating disconnector 6, in dust absorption fan 5 outlets, be provided with return air bend pipe 4, a dust shield 2 covers mouthful corresponding dirt pits top that is arranged on bulk cargo material blanking tube 8 bottom sides, the outlet of dust absorption fan 5 is communicated with the middle part of bulk cargo material blanking tube 8 by return air bend pipe 4, while installing and using, the taper dust mouth correspondence of energy dissipating disconnector 6 is in bulk cargo transporting groove 7, when user is when bulk cargo transfer point is provided with material blanking tube, can save bulk cargo material blanking tube 8, with user's bulk cargo material blanking tube adapted.
Model machine is through Installation and trial run on the loose coal delivery system of local coal transfer point, dependable performance, good dustproof effect, and test personnel expect that this bulk cargo transfer point material blanking tube dust-arrest device applies at each greatly loose coal transfer point early.
