Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of overlength distance embolism formula air-transport system, as shown in the figure, it comprises storage tank 1, feed bin 5 and N(N >=1) the main feed pipe 4 of bar, N(N >=2) the main feed pipe 4 of bar is arranged in parallel, the main feed pipe 4 of every bar is connected with ceramic elbow 19, the mouth of the main feed pipe 4 of every bar is connected with feed bin 5, and the service direction along material on the main feed pipe 4 of every bar has been arranged in parallel at least two pieces points of feed pipes 20, and every root divides feed pipe 20 to be connected with one group of feed arrangement 7.
Wherein, feed arrangement comprises hopper 6 and transmission pump 14, described hopper 6 is connected by feed pipe with transmission pump 14, the top of described transmission pump 14 is provided with inlet valve 16, bleeder valve 9 and level-sensing device 15, described inlet valve 16 is connected with feed pipe, the upper end of inlet valve 16 is from up to down connected with hand operated gate valve 18 and expansion joint 17 in turn, by feed pipe, hopper 6 is communicated with transmission pump 14, described bleeder valve 9 is connected with a point feed pipe 20, and the material in transmission pump 14 enters main feed pipe 4 by a point feed pipe 20.The lower end of described transmission pump 14 is connected with air intake assembly 8, and this air intake assembly 8 comprises air inlet pipe 12 and the gas control shutoff valve 10 be successively set on air inlet pipe 12 and non-return valve 11.The lower end of transmission pump 14 is provided with gasification installation 13, and this gasification installation 13 adopts gasification board, and this gasification installation 13 is positioned at the top of air inlet pipe 12 and transmission pump 14 coupling end.
Described storage tank 1 is connected with horizontal compression gas pipe 2 and air feed pipe 21, multiple air conveyor 3 is evenly provided with between described compression gas pipe 2 and main feed pipe 4, the structure of this air conveyor 3 adopts the structure that application number is a kind of air conveyor disclosed in the utility model patent of 201320013741.4, distance between adjacent air conveyor 3 is 4m, described air feed pipe 21 is connected with air intake assembly 8, and storage tank 1 is air inlet pipe 12 air feed in air intake assembly 8 by air feed pipe 21.
During use, horizontal compression gas pipe 2 is connected with storage tank 1, preferably between compression gas pipe 2 and main feed pipe 4, fills a set of air conveyor 3 every four meter amperes.Material in hopper 6 enters after transmission pump 14 through inlet valve 16, air inlet pipe 12 in air intake assembly 8 is to transporting compressed gas body in transmission pump 14, make supercharging in transmission pump 14, material enters point feed pipe 20 through bleeder valve 9, enters main feed pipe 4, be full of the pipeline of main feed pipe 4 at material after by a point feed pipe 20, now, have material place to start boosting in main feed pipe 4, air conveyor 3 is opened and is started by-carriage pressure gas 2 in main feed pipe 4, carries out mass transport.Because air conveyor 3 fills every four meter amperes, so, when can ensure to carry out extra long distance or even infinity from conveying, mainly send materials in the tube 4 to block.
Spacing between adjacent two air conveyors 3 can according to the caliber of main feed pipe 4, pumped (conveying) medium, fed distance and ceramic elbow 19 the factor such as layout determine.Transmission pump 14 air inlet adopts bottom static pressure air inlet, and transmission pump 14 admission port adopts reducing valve, keeps certain constant voltage lower than bleed pressure during conveying in transmission pump 14, the operational throughput of total bleed pressure and requirement is depended in the height design of pressure, pressure is high, then ash discharge speed is fast, and transport efficiency is just high.Full packages conveyings in the exit of transmission pump 14, when there is plugging situation to certain distance in medium transport, pressure in main feed pipe 4 can raise, if the pressure in main feed pipe 4 reaches the response pressure of air conveyor 3, air conveyor 3 can open air inlet in main feed pipe 4, medium in main feed pipe 4 is subject to the disturbance of air inlet, can be automatically loose, the plugging phenomenon of this point is eliminated, now air conveyor 3 is closed, medium in main feed pipe 4 moves forward, achieve the mode of operation of the some air inlet of plugging place, not stifled place not air inlet, plugging phenomenon stops air inlet after eliminating, so save compressed-air actuated consumption to the full extent, and fed distance can realize the conveying of infinity, fed distance is far away, solar term effect is more obvious.
Novel embolizing formula carry maximum advantage be exactly stable, gas consumption is few, pipe wear is low and transport efficiency is high.When fed distance is far away, adopt this delivery system more can save compressed-air actuated consumption.This delivery system can realize pipeline uninterrupted duty, when the medium in transmission pump 14 enters the air inlet that just can stop this transmission pump after main feed pipe 4 completely, other transmission pump 14 relay be arranged in parallel with this transmission pump is carried, realize the uninterrupted duty of main feed pipe 4, this kind of mode of operation not only can save a large amount of purging gas, can also reduce the wearing and tearing of main feed pipe 4 and ceramic elbow 19.
Material enters transmission pump 14 from hopper 6 through expansion joint 17 and inlet valve 16, measured in real time by level-sensing device 15 and show the position of material, when material reaches desired location, open gas control shutoff valve 10, compressed gas starts to pressurize to transmission pump 14 through non-return valve 11, when pressure is increased to desirable value, open bleeder valve 9, the material in transmission pump 14 enters main feed pipe 4 from bleeder valve 9 after gasification installation 13 fluidisation.After being full of material in main feed pipe 4, inside starts boosting, when pressure is elevated to the unlatching value of air conveyor 3, open air conveyor 3, because air conveyor 3 is connected with compression gas pipe 2 and main feed pipe 4, after air conveyor 3 is opened, compressed gas starts tonifying Qi in main feed pipe 4 by air conveyor 3, material in main feed pipe 4 can move to feed bin 5 direction, where material moves to, air conveyor where 3 will be opened, compression gas pipe 2 starts tonifying Qi in main feed pipe 4 by air conveyor 3, until material is all transported to feed bin 5 through ceramic elbow 19.
Can existing techniques in realizing be passed through without the technical characteristic described in the utility model, not repeat them here.The foregoing is only preferred embodiment of the present utility model; the utility model is not limited in above-mentioned detailed description of the invention; the change that those of ordinary skill in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
