Description
The present invention relates to the strength pipeline conveyer.
In branch of industry, with powder and granule shape material a lot of as raw material or product, in order to improve the operating rate of loading and unloading, transportation, the saving labour power is improved working conditions, and adopts strength ducting form in recent years both at home and abroad widely.But existing Pneumatic conveyer only is to be applied to the conveying than the material of rule of lightweight, fine and shape, as cereal, beans, cement, pulverized limestone, chemical fertilizer, plastic grain goods etc. (seeing that (day) hunting is wild military outstanding: " powder and granule shape material feedway ").Pneumatic conveyer for the stone grain of heavy, corase particles and the non-rule of shape and ore etc. does not appear in the newspapers as yet.
As everyone knows, the weight of heavy particles such as stone grain and ore is much bigger far beyond beans, chemical fertilizer etc., and its shape is very irregular, and its big or small difference is also very greatly different, so general Pneumatic conveyer is inefficient.The purpose of the stone collector that negative pressure strength of the present invention is carried is the transportation problem for stone grain that solves heavy, corase particles and the non-rule of shape and ore etc., make the raw material conveying in infrastructure project, harbour, water transport and the mine construction can realize mechanization, improve working conditions, improve operating rate and economic benefit.
In the stone collector that negative pressure strength of the present invention is carried, can do upward movement and conveying in order to make heavy corase particles (stone grain, ore etc.), key is that the suction of shape reasonable in design chews and control the pressure of air-flow, inlet air flow is fully quickened, cause the stone grain under kinetic pressure and barometric pressure (suction is negative pressure in chewing) effect, to chew upward movement and enter conveying pipeline from suction.And in the design of horizontal material separator, can separate by by gravity for making the heavy corase particles in the two phase flow (air and stone grain), and, in horizontal material separator, be provided with vertical plate washer in order to collect less stone grain and chicken girt.For reduce stone collector in operation process the stone grain to the frequent collision of conveying pipeline wall and the wearing and tearing of the conveying pipeline wall that is caused, the particularly wearing and tearing of the bent tube section of conveying pipeline, the bent tube section of conveying pipeline is designed to the rectangular tube of large-size in stone collector of the present invention, reduce the ascending velocity of stone grain, reduce its wearing and tearing; And except adopting the abrasion resistant material, also makes the form that can change in part easy to wear to tube wall.Be provided with two flashboards up and down in the discharger of stone collector, rely on control system that two flashboard cyclic periodicity ground are opened and the sealing action, thereby realized carrying out under the vacuum source condition discharging, not only discharging is convenient, and has guaranteed the stable of whole stone collector vacuum work state.Because of whole stone collector is to be in work under negative pressure (vacuum) state, so the each several part of machine all must be carried out vacuum seal.
Each parts of the stone collector that the negative pressure strength is carried describe with reference to the accompanying drawings.
Figure one is the integral structure scheme drawing of the stone collector of negative pressure strength conveying.The stone collector that the negative pressure strength is carried is chewed (2) by rotating to inhale, and conveying pipeline (3), horizontal material separator (4), discharger (5), proliferation cyclone (6), freeing pipe (7), roots blower (8), silencing unit (9), the movable supporting body of stone collector (13) are formed.Wherein telescoping mechanism (1), luffing mechanism (10), rotating mechanism (11) are made the regulating mechanism that the three degree of freedom of top to bottom, left and right, front and rear moves for controlling conveying pipeline (3); Open and the usefulness of sealing by cyclic periodicity for the last lower flashboard in the control discharger (5) is done for control system (12); Silencing unit (9) for the noise design-calculated parts proliferation cyclones (6) that reduce stone collector and produce in the running by air inlet pipe, cylinder, the body of falling Cone, formed by dirt bucket, radiation shield and freeing pipe, when containing grit, powder and enter dust exhaustor at a high speed in company with gas, thrown to wall at centrifugal action and to stand dirt bucket degeneration and discharge, stone collector is placed on the movable supporting body (13), makes stone collector can adapt to variation and (14) coordination of stone grain heap of material position.The movable supporting body of stone collector can be made movable hull in harbour, uses on land such as mines and can make movable massive plate car.(15) be band conveyor.
Figure two inhales the scheme drawing of chewing for rotating.Rotate inhaling the design of chewing is the key of stone collector, because of the stone grain is inhaled into conveying pipeline with air by rotating to inhale to chew, inhales comparatively speaking therefore that to chew be the loader of aspiration-type feeding device.For making the conveying of in conveying pipeline, rising of stone grain, the air-flow that suction is chewed should maintain certain speed, air from air volume regulator (21) by inner suction pipe (22) and outside slit annular region between the rotating casing (23) enter, the size of air inlet air quantity is regulated by the inlet flow resistance that changes air volume regulator (21), and the small part air-flow enters around the bottom that suction is chewed.For being mixed with air-flow, the stone grain forms dual-phase jet bundle with certain flow rate, the stone grain obtains the momentum setting in motion from jet beam, fully mixing formation stone grain stream with air-flow is transferred, so should selecting the bottom of appropriate And and inner suction pipe to make the loudspeaker with certain angle, the gap between inner suction pipe (22) and the outer rotating casing (23) dehisces, the bottom of inner suction pipe and the bottom of outer rotating casing are mounted to and maintain certain height difference d(and be generally 10～30 centimetres) to attract efficient and air-flow is evenly entered in order to improve, stone collector of the present invention adopts rotary type to inhale and chews, promptly make outer rotating casing (23) make circular movement with respect to inner suction pipe (22) (fixing) by Worm wheel transmission mechanism (24), the rotating speed of outer rotating casing is 45～90 rev/mins.Two above well-distributed loose metal cuttves (25) are equipped with in the bottom of outer rotating casing, and constantly entad loosening with the stone grain that outer rotating casing rotates around making at the loose metal cutter (25) of stone collector work, auxiliary stone grain enters conveying pipeline.
Figure three is the scheme drawing of conveying pipeline.The conveying pipeline of the stone collector that the negative pressure strength is carried with rotate suction and chew (2), horizontal material separator (4) be connected (seeing figure one).Conveying pipeline is by straight tube (31), with straight tube horn interface (32), crooked rectangular tube (33), form with the horn interface (34) of horizontal material separator.Because the dual-phase jet of stone grain and air is inhaled the straight-tube portion rising conveying of chewing along conveying pipeline from rotating, to become horizontal motion then and enter horizontal material separator, stone grain and air-flow are to move along a curved path, this will make the stone grain often and duct wall bump and rub, thereby cause tube wall very easily to wear and tear.Its flow velocity the two phase flow of stone grain and air is slowed down lower degree of wear, but the too low stone grain that can not drive again of the flow velocity of two phase flow enters horizontal material separator, so will be controlled appropriately to tube wall.Therefore, do squarely at the curve of conveying pipeline, And enlarges its size, and in its part easy to wear except adopting the abrasion resistant material makes, also make disconnectable cover plate (35).
Figure four is the scheme drawing of horizontal material separator.Horizontal material separator is made up of with vertical plate washer (45) induction pipe (41), airflow outlet pipe (42), casing (43), building stones outlets (44).For the flow velocity that makes two phase flow and air-flow more reduces, to import and export pipe (41) and (42) and be designed to the increaser form, the casing of disconnector is made the big rectangular box (43) of convergent.The two phase flow that air-flow mixes with the stone grain enters from airflow inlet pipe (41) horizontal direction, because the long-pending sudden enlargement of container section, the flow velocity of two phase flow reduces suddenly, stone grain separated and vertical sedimentation under gravity, air-flow kinetic pressure and fluid resistance effect.Can vertically be deposited to building stones and export (44) in order to make less stone grain be difficult for leaping outlet and medium stone grain with air-flow, minimizing is to the bump of casing rear wall, vertical plate washer (45) is set in horizontal material separator, plate washer is installed in the place of the close a little air stream outlet of casing, and the width that its height should be able to shield be lived air stream outlet just can reach and make light gravelstone grain and air separation sedimentation effectively, and the top of plate washer is made up of double layer material, to strengthen its impact resistant capability.
Figure five is the scheme drawing of discharger.The effect of discharger is the building stones in the horizontal glassware to be discharged by band conveyor carry and transhipment.Because the top of discharger is connected and interior logical negative pressure source of the gas with horizontal material separator, bottom discharger mouth (54) is again a barometric pressure, thereby can occur can't sedimentation discharging the phenomenon of being detained owing to draught head causes the stone grain by its deadweight.Therefore, in the discharger of stone collector of the present invention, adopt the design of double-deck gate.The control system of forming by electronic time programming controller, two position four-way solenoid valves and discharger (53), tail gates (51) and (52) can be opened and sealing on repetition period ground, promptly when upper lock gate (51) is opened, tail gates (52) sealing makes the stone grain drop in the dumper body (55) by deadweight; When upper lock gate (51) sealed, tail gates (52) were opened, and building stones drop on the belt of band conveyor (15), have so both made the sedimentation successfully of stone grain, keep the vacuum state of stone collector again, reduced the living load of stone collector.
