Abstract
The air film adjusting device for air cushion belt-type conveyer comprises an adjusting sliding bush, a distance sleeve, a spring sealing gasket and adjusting bolts. The height of the sliding bush extended outside a panel is regulated to obtain the optimum thickness of the air film so that the air consumption of the complete appliance is lowered, with energy saving. When the conveying belt appears bulge because of no load or light load, the slit produced between the conveying belt and the upper end face of the adjusting sliding bush is used to deflate the air and relive the pressure so that the bulge is eliminated to keep a stable and homogeneous working air film. The utility model has the advantages of simple structure, easy fabrication, low cost, convenient adjustment, air and energy saving, etc.
Description
The utility model is a kind of air cushion-belt conveyer air film setting device.
Air cushion-belt conveyer is that China develops a kind of faster novel band conveyer over past ten years, is widely used in occasions such as station, port and pier, factory, mine, can carry out the conveying of material high-speed smooth.The load-transfer device of air cushion-belt conveyer is worked by the support that the film of calming the anger is arranged of its underpart, and therefore how forming and keep the stabilized uniform air film is the steadily key of normal operation of air cushion-belt conveyer.Now use air cushion-belt conveyer in material conveying process, because feed is inhomogeneous, when zero load or underloading occurring, under gas pressure, load-transfer device local projection occurs and influences the normal operation of conveyer.The air film pressure relief device that Britain Simou company makes is as Fig. 1. shown in, be that the thin plate that employing is fixed on the panel 4 is the thickness that fixed limit plate 1 is controlled air film 5, and by fixedly unloading air-casing 2 releases, but owing to can not in time adjust to air film 5, the installation and processing precision of fixed limit plate 1 is difficult to again guarantee, the realization of processing technology is also comparatively difficult, simultaneously because air cushion-belt conveyer air chamber 3 adopts the method for central gas supply usually, one linear loss is arranged as shown in Figure 3 from air feed top, air-film thickness is away from the attenuation gradually of source of the gas position, its minimum is Smin, and this air film pressure relief device that Britain Simou company makes adopts the fixed limit plate 1 that is fixed on the panel to limit air-film thickness S
o, can not adjust air-film thickness along the journey each point, so for keeping the normal operation of load-transfer device 6, required work air-film thickness should be greater than Smin, so just force that will to improve the complete machine air-film thickness in design be h
o, h wherein
oWith s
oBetween difference be △
o, cause very big strength loss V.
The purpose of this utility model is to solve the deficiency that prior art exists, and a kind of adjustable air film venting pressure relief device is provided, and can in time eliminate load-transfer device because the projection that zero load or underloading occur keeps stable air film, the problem that the solution strength is lost.
The utility model is to take following technical scheme to realize: the utility model is made up of adjustment sliding sleeve 7, distance sleeve 8, spring sealed rubber cushion 9, adjusting bolt 10 as shown in Figure 2.Adjust sliding sleeve 7 and have identical following hole, aperture 11 and following hole 12 with the bottom of distance sleeve 8, adjusting sliding sleeve 7 is inserted in the distance sleeve 8, can go up by distance sleeve 8 guiding, move down, distance sleeve 8 bottoms are fixedly mounted in the air chamber 3 by regulating bolt 10, regulate the upper end of bolt 10 and withstand the lower end of regulating sliding sleeve 7, can carry out the adjustment location of lifting according to the thickness Smin of minimum air film layer to adjustment sliding sleeve 7, regulate bolt 10 in around the hole 11 under the adjustment sliding sleeve and the following hole 12 of distance sleeve on every side and be fixed with spring sealed rubber cushion 9, in order to the space between sealing adjustment sliding sleeve 7 and the distance sleeve 8.
When the conveyer normal operation, load-transfer device 6 is by the support of stablizing air film 5, is close to adjust sliding sleeve 7 upper surfaces and slide, and covers to adjust sliding sleeve endoporus 13 and make it not produce leakage, and the work air-film thickness of this moment is S, through regulating the adjustment of bolt 10, this moment S
oCan be roughly near in addition can equal Smin, when load conveyor alleviates suddenly, the pressure relief of air film 5, and the air pressure in the air chamber 3 that communicates with it is constant voltage, thereby pore 14 inside and outside pressure reduction are strengthened, the gas that enters air film 5 from air chamber increases, the elevated thickness that makes air film 5 is to h, form the projection of load-transfer device 6, produce slit △ this moment between the upper surface of load-transfer device 6 and adjustment sliding 7, the gas that makes air film 5 overflows simultaneously from two of load-transfer device 6, also via the endoporus 13 of adjusting sliding sleeve, flow out in the following hole 12 of following hole 11 and distance sleeve and the venting release reduces air film 5 thickness, and when reducing to thickness when being S, load-transfer device 6 covers the endoporus 13 of adjusting sliding sleeve again, keep stable work gas film pressure thereby reach, realize the purpose of steady convey materials.Move owing to adjustment sliding sleeve 7 liftables of the present utility model simultaneously, only need regulate the height S that adjusts sliding sleeve 7 extending panels 4 along the journey each point just can to make the work air-film thickness be that S is unlimited approaching or equal the minimum Smin that air-film thickness requires with regulating bolt 10, so just can obtain most economical air film height and eliminate the strength loss, and because of airshed is the variation that cube is directly proportional with the air film layer height, thereby stablize under the prerequisite of air film layer height guaranteeing, air-film thickness is more little, and energy-saving effect is remarkable more.
Advantage of the present utility model is: simple in structure, easy to manufacture, easy to adjust, and be a kind of wider energy-saving safe setting device of face that uses.
