Abstract
The utility model relates to a belt conveyor with a gasket seal, comprising rollers, idlers, a conveying belt, an air box and a sealing device. The air box is arranged below the conveying belt and provided with a plurality of air holes. The pressure air extracted upwards in the air box forms a fine air-cushion between the conveying belt and the air box so that the conveying belt almost is lain in a suspended state above the air box during the conveying process to reduce the frictional resistance of the conveying belt and to enhance the conveying speed of the conveyor. The sealing device is provided to reduce the loss of the pressure air and meanwhile to enhance the working performance of the conveyor.
Description
The utility model belongs to a kind of belt conveyer, particularly is provided with the belt conveyer of sealed air cushion.
At present all adopt belt conveyer to carry generally speaking for the conveying of bulk material both at home and abroad, its structure adopts the belt conveyer that is provided with a plurality of carrying rollers below load-transfer device usually, and the conveyer of this structure existing problems at present has:
1, it is more to support the carrying roller quantity of load-transfer device, and the possibility of damaging big, be prone to mechanical breakdown.
2, be in contact with one another between load-transfer device and the carrying roller, in operational process because the action of gravity of material, make the bigger dynamic friction of appearance between load-transfer device and the carrying roller, even because the amount of deflection between carrying roller and carrying roller support belt, in service, material will impact with carrying roller, cause vibration, thereby should not improve the belt speed of conveyer, limited the raising of operational throughput.
3, in operational process,, be unfavorable for the normal operation of conveyer because factors such as the tensile force of distribution of load inequality and load-transfer device and accuracy of manufacture are prone to load-transfer device sometimes and run phenomenon partially.
Provide order of the present utility model a kind of be beneficial to improve conveyor speed, reduce friction drag, sealed air cushion belt conveyer that energy loss is little.
The utility model adopts following organization plan to realize.Existing carrying roller belt conveyer is improved to blanket gas cushion belt conveyer, its structural feature is: below the load-transfer device of conveyer, be provided with gas tank, be provided with a plurality of pores above the gas tank, load-transfer device rides in above the gas tank, with around the sidepiece that gas tank " contacts ", be provided with sealing arrangement (packing seal) at load-transfer device.During work, pressure air upwards flows out by the aperture that gas tank is provided with above, because the sealing arrangement that is provided with around load-transfer device and the gas tank sidepiece, make it between load-transfer device and gas tank, to form an air cushion, load-transfer device is floated, whole air-flow is by exhaust to atmosphere in the moving gap between load-transfer device and the sealing arrangement (packing seal), making load-transfer device so almost is to be in " suspension " state in operational process, thereby reduced the running resistance of load-transfer device greatly, obviously improved the delivery speed and the work efficiency of conveyer.Owing to be provided with sealing arrangement, can make full use of pressure air like this, make to form a good air cushion between load-transfer device and the gas tank, reduced the gas outflow, saved a large amount of energy consumptions, also improved the service life of load-transfer device in addition greatly.And working stability, fault rate is low.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is cross-section cutaway views of the present utility model.
Below in conjunction with accompanying drawing the utility model is elaborated.
Find out with reference to accompanying drawing 1, whole load-transfer device (2) is by head roll (1) gas tank (3), changed course cylinder (7), transition carrying roller (6), return idler (5) is supporting, below load-transfer device (2), be provided with gas tank (3), be provided with a plurality of pores above the gas tank, be arcuation depression shape structure (seeing accompanying drawing 2) above the gas tank (3), and the width of gas tank (3) is less than the width of load-transfer device, sealing arrangement (packing seal) (9) fixedly is housed around the sidepiece of gas phase, when off working state, the bottom surface of load-transfer device (2) contacts with packing seal (9), when work, head roll (1) drives load-transfer device (2) motion, this moment, blowing engine passed through ventilation inlet (4) air draft in gas tank, and the pressure air in the case outwards flows out by top aperture (10), owing to the effect of packing seal, make above the gas tank and load-transfer device (2) below between form good air cushion (8), transmit work thereby load-transfer device (2) almost is in " suspensions " state ground on gas phase.
Claims (3)
1, a kind of sealed air cushion belt conveyer, it is made of cylinder, carrying roller, load-transfer device, it is characterized in that: be provided with gas tank below load-transfer device, be provided with a plurality of pores above the gas tank, load-transfer device rides in above the gas tank, with around the sidepiece that gas tank contacts, is provided with sealing arrangement at load-transfer device.
2, according to the described conveyer of claim 1, it is characterized in that: the top curved depression shape structure of gas tank.
3, according to the described conveyer of claim 2, it is characterized in that: the width of gas tank is less than the width of load-transfer device.
