Abstract
The invention discloses a sealed conveyer for conveying blocky and granular materials in mines or other industries, which is formed by fixing a helical blade (3) arranged in a conveying pipeline (2) on a helical shaft (4) and connecting the helical blade with a power source (19), wherein each segment of helical shaft (4) and each segment of helical shaft (10) are connected together through a roller (6), and the roller (6) is supported on a supporting roller (11) arranged outside the roller. When the screw (3) is driven by the power source (19) to rotate in the conveying pipeline (2), the material is pushed to be conveyed in a certain direction. Because the conveying pipeline is internally provided with no bearing support, the phenomena of wedge clamping and blockage are eliminated, and the energy consumption is greatly reduced.
Description
The present invention relates to a kind of sealing conveyer that is used for mine or other industry conveying bulk and bulk granular material.
Convey materials in mine, generally adopt travelling apron, mine car, scrape load transfer devices such as receiving conveyer, particularly carry coal, because these equipment are open conveying, easily produce coal dust, gas, coal slime distribution down-hole everywhere, pollute the environment and the air of mine, the infringement health also may cause coal dust, gas explosion.These load transfer device volumes are also very big, taken the big quantity space of roadway, and shaft sinking and drifting and investment are all increased greatly.
At present at the conveyor screw of sector applications such as cement, have characteristics such as closed conveying, volume be little, simple in structure.But conveyor screw is because of only depending on the spiral rotation progradation convey materials in its delivery duct, and transport efficiency is very low, and traffic capacity is also very little, generally below 100t/h.The bearing of this conveyer and bearing seat are located in the delivery duct, and easily by card wedge, obstruction, transporting resistance is very big when carrying for material, and the conveyer energy consumption is big; Because material produces friction with conveying pipeline inner wall when carrying, make that the equipment component wear is serious again, also make the energy consumption increase of conveyer.These problems of conveyor screw have limited its field of application, do not adopt substantially in mine.
The purpose of this invention is to provide a kind of sealing conveyer, it can solve material effectively when carrying, because of card wedge, obstruction takes place and because of parts such as wearing and tearing delivery ducts in material in delivery duct, and cause that the conveyer energy consumption is big, motor easily overload problem such as burn.
The object of the present invention is achieved like this: mine sealing conveyer is made up of delivery duct, helicallobe, screw shaft and propulsion source, helicallobe and screw shaft are fixed as one, between each section screw shaft, connect by cylinder, idler is in being located on its exterior idler pulley, can be around the rotational of screw shaft, cylinder inside can straightway passage for material.The drive power source spiral rotates in delivery duct, promotes material and carries to certain orientation along delivery duct, through cylinder in-to-in passage, enters in next joint delivery duct.
Mine sealing conveyer can also be, form by delivery duct, helicallobe, screw shaft and propulsion source, helicallobe and screw shaft are fixed as one, be subjected to drive power source, in delivery duct, rotate, be provided with air cushion in the bottom of delivery duct and form the chamber, be communicated with delivery duct, pressurized air forms the chamber from air cushion and enters delivery duct, forms air cushion and overcomes material to machine members such as pipelines, thereby reduce the conveyer energy consumption.
The above realizes that the object of the invention dual mode can also be an one comprehensively, better effects if.
Because mine sealing conveyer is the duct type structure, stenosis such as the interior no bearing seat of delivery duct are provided with air cushion formation chamber generation air cushion and can overcome material to machine members such as delivery ducts.Therefore this conveyer has characteristics such as sealed type is carried, volume is little, energy consumption is low, also have dependable performance, easy to maintenance, traffic capacity can satisfy different requirements, advantages such as laying length is flexible, as in many industries, particularly in the colliery, using, will produce the enormous benefits of environmental protection, safety, economic dispatch aspect.
Below in conjunction with drawings and Examples the concrete conveyer that the present invention proposes is described in further detail.
Fig. 1 is the lateral plan of the embodiment of mine sealing conveyer of proposition according to the present invention, and delivery duct is by partly cut-away among the figure.
Fig. 2 is the cross sectional drawing of another embodiment of mine sealing conveyer of proposition according to the present invention.
A kind of embodiment of mine sealing conveyer of the present invention as shown in Figure 1, form by delivery duct (2), helicallobe (3), screw shaft (4) and propulsion source parts such as (19), methods such as helicallobe (3) and screw shaft (4) employing welding are fixed as one, in rotation in delivery duct (2) under the driving of propulsion source (19).Connect by cylinder (6) between each section screw shaft (4), (10), cylinder (6) is supported on the idler pulley (11) and can rotates.Between cylinder (6) and delivery duct (2), be provided with sealing arrangement (5).The section form of delivery duct (2) preferably adopts circle.
Cylinder (6) is made up of circular cylinder body (7), helicallobe (8) and screw shaft (9); Helicallobe (8) is fixed on the screw shaft (9), and its periphery is fixed with the inwall of circular cylinder body (7) again, and forming a material can straightway helical duct.Link together by the screw shaft (9) in the cylinder between screw shaft (4) in the delivery duct (2), (10).
Sealing arrangement (5) can adopt the seal ring of calming the anger, and an end keeps minim gap to be enclosed on the cylinder (6), and the other end and delivery duct (2) are fixing.The calm the anger inside of seal ring is the flute profile passage, the input pipe of calming the anger (12) and this channel connection.After charging into pressurized air in the seal ring, can play sealing function.Certainly, sealing arrangement (5) also can adopt existing various packing technique.
In order to improve the transport efficiency of material, reduce the conveyer energy consumption, be provided with pressure input pipe (17) at the material input end of conveyer and be communicated with delivery duct (2); The pressure input pipe is partial to the axis one side installation of screw shaft (4), makes the flow direction of calming the anger (16) of input opposite with the hand of rotation (15) of spiral, resist material (14) and rotate with spiral, and it is mobile to direction shown in (13) to promote material.
The another kind of embodiment of mine sealing conveyer of the present invention as shown in Figure 2, form by delivery duct (21), helicallobe (20), screw shaft (22) and propulsion source (in Fig. 2, not drawing), helicallobe (20), screw shaft (22) are fixed as one, drive rotation in delivery duct (21) by propulsion source; The bottom of delivery duct (21) is provided with air cushion formation chamber (25) and is communicated with the bottom of delivery duct (21).It is the flute profile air chamber that air cushion forms the chamber, adopts methods such as welding or bolted connection to be fixed on the bottom of delivery duct (21), can pass through eyelet (24) to be communicated with delivery duct (21), and the input pipe of calming the anger (27) forms chamber (25) with air cushion and is communicated with.When pressurized air (26) enters delivery duct (21) by eyelet (24), just form one deck air cushion, the material supporting is got up, and under the promotion of spiral (20), carry to certain orientation.
More than the propulsions source that adopt of two kinds of embodiment, both can adopt electrical motor, also can adopt pneumatic motor.Electrical motor should adopt fire proof motor in highly gassy mine.
The conveyor construction of above-mentioned two kinds of embodiment can comprehensively be an one also, carries better effects if.
