Abstract
The utility model discloses a material balanced feeding mechanism for a belt conveyor, which is mainly applied to configuration for a conveying equipment system for powdery materials and sandy materials. The feeding mechanism is composed of two components, namely, a suspended homogenizer and a pneumatic chute, wherein after starting and running, a cyclonic air stream always exists in the suspended homogenizer, the powdery materials and the sandy materials at the bottom of an unloading bin are mixed and stirred with the cyclonic air stream, and in a suspended state, the materials on the lower part of the unloading bin and air can only pass through a suspended discharge pore plate and uniformly flow in the pneumatic chute through a gate valve under the impact action of the cyclonic air stream and the gravity action of the materials, and in the closed state of the sandy materials at the top of the bin; and after the sandy materials flow in the pneumatic chute, the materials generate an effect of secondary uniform distribution by virtue of a wind power top-blowing action in a wind pressure groove in the bottom of the pneumatic chute and constant-speed inclined suspended slide, thus guaranteeing that the powdery materials in the unloading bin can incompactly and uniformly into the belt conveyer.
Description
technical field:the balanced feeder of Air-cushion Type Belt Conveyer of the present invention is mainly used in the configuration of powdery and sand-like material transfer equipment system.
background technology:powdery and sand-like material from discharge bin toward make land used be rewinding point conveying now the Air-cushion Type Belt Conveyer that adopt more carry, adopt from discharge bin to belt feeder charging process more and directly by the mode of tremie pipe feed, undertaken, with the flow of shutoff valve control material.Feed is balanced, and load is evenly the key of band conveyor smooth running.
But affect the harmony of material from discharge bin to belt feeder material feeding point feed, the harmony of feed flow is subject to various factors, not discharge bin bottom tremie pipe is that a flow control on belt feeder supply pipe cuts valve and can lock.As self physical property of sand shape material, in discharge bin material number, degree of firmness etc. all may affect reinforced harmony.
Existing general powdery and sand-like material are from discharge bin toward band conveyor feed-type, earthquake feeder is not suitable in the situation of conveying of granular material, the tremie pipes that adopt add the feed mode of movement of stream material control cock more, and this kind of feed-type has following two shortcomings:
The one, in discharge bin, during granular material poor fluidity, easily in the upper end of feed bin inner bottom part tremie pipe, form crust, cause and arrhea fracture phenomenon, cause band conveyor idle running, carry logistics to interrupt, easily to continuous production processes, cause stopping production accident.
The 2nd, granular material good fluidity in discharge bin, material is more, while being subject to load fusion, easily cause characteristic of concentration to impact reinforced, destroy band conveyor harmonious, cause local overload, cause belt wearing and tearing aggravation, often so can cause the generation of the accident of belt fracture, impact is normally produced.
summary of the invention:summary is described feeds in raw material uniformly in discharge bin toward belt feeder, not only can guarantee the band conveyor running of equilibrium continuously, reduce the generation of band conveyor transmission failure, can also guarantee to produce the carrying out of continous-stable, reinforced from discharge bin toward band conveyor in order to overcome existing powdery and sand-like material, employing is directly carried out feed with tremie pipe to band conveyor from discharge bin, with shutoff valve, control the defect that this feeder of flow of material brings, guarantee the equilibrium operating of band conveyor.The invention provides and a kind ofly can guarantee that powdery and sand-like material can add materials to band conveyor uniformly from discharge bin, guarantee the charging gear of the balanced convey materials of band conveyor.
Band conveyor material balance feeder of the present invention, be arranged between discharging Hatch Opening and band conveyor, its technical characterictic is: between discharge bin and band conveyor, be provided with balanced charging system device, this equilibrium charging system device is by floated harmonious material device and air-driven chute and formed to supply air system.
According to technique scheme: the bottom discharge openings place at discharge bin, is provided with floated harmonious material device.
This floated harmonious material device is by blanking sleeve pipe, and suspension homocline orifice plate, flow-controlling gate, appendix joint, butt flange structure form, and this flow-controlling gate adopts gate valve conventionally, and during work operation, the outer end of appendix is connected with pressure airduct by valve.
According to technique scheme: the lower end at the floated harmonious material device of discharge bin bottom is provided with mass transport air-driven chute, the feed end of its air-driven chute is connected with the blanking sleeve pipe of floated harmonious material device lower end, the discharge end of air-driven chute is a little connected with connecting material of band conveyor through blanking conduit, the bottom of air-driven chute with to wind pipeline, be connected.
According to technique scheme: be arranged on discharge bin bottom and be comprised of two large parts with balanced charging system device between band conveyor is actual, one is floated harmonious material device, a formula air-driven chute.After starting operation, in floated harmonious material device, there is all the time the existence of cyclonic current, together with the flour sand shape material of discharge bin bottom can mix stirring with cyclonic current, in suspended state, under the closed state of feed bin top sand shape material, under the impact effect of its cyclonic current and the Action of Gravity Field of material, the material of discharge bin bottom and general mood can only, by suspension blanking orifice plate, flow in air-driven chute through gate valve uniformly; When sand shape material flow into after air-driven chute, material slips through effect and the suspension of inclination at the uniform velocity of wind-force top blast in the blast groove of air-driven chute bottom, can make material produce the uniform effect of secondary, so just complete balanced blanking system, i.e. a band conveyor material balance feeder between discharging Hatch Opening and band conveyor, have been formed being arranged on.
Floated harmonious material device is set in discharge bin bottom not only can make the flour sand material in feed bin reinforced to band conveyor uniformly, and under the impact effect of cyclonic current, the granular material that can prevent discharge bin bottom produces crust phenomenon, guarantees that granular material in discharge bin can loosely flow in band conveyor material balance feeder uniformly to go.
In flour sand shape material-transporting system device, adopt band conveyor material balance feeder of the present invention, can prevent due to can not evenly the feed in raw material generation of unbalanced phenomena of the band conveyor convey materials that causes of charging system, thereby reduce the generation of the belt feeder transmission failure therefore causing, to guarantee the continual and steady operation of whole production system.
Accompanying drawing explanation:
The technical scheme of band conveyor material balance feeder of the present invention and feature are more clear with specific embodiment by reading accompanying drawing explanation.
Fig. 1 is the elevational schematic view of band conveyor material balance feeder of the present invention.
Fig. 2 is the plan sketch of the cyclone homocline orifice plate in floated harmonious material device.
Shown in its figure: 1) wind pipeline system, (8) suspension blanking orifice plate, (9) appendix joint are given in discharge bin, (2) floated harmonious material device, (3) flow-controlling gate, (4) air-driven chute, (5) tremie pipe conduit, (6) Air-cushion Type Belt Conveyer, (7).
