Abstract
The utility model relates to a rib type air chamber device for an air-cushion belt type conveyer. Conveyer belts are respectively arranged on four and two circular arc-shaped ribs of an upper and a lower branch air chambers. Air is sent to the interior of an air passage of the air chambers by a blower during working time, and is sent under the conveyer belt through air holes on a top plate of the air passage; the conveyer belt and the material on the conveyer belt are supported by pressure air and air cushions formed by the air leakage at rib positions, and the running frictional property of the conveyer belt is improved. As the contact area of the device and the conveyer belt is small, the device has the advantages of tight closure, high utilization rate of the wind energy, good air cushion forming, simple structure, easy manufacture and low manufacture cost; the utility model is suitable for conveying various bulk materials under general conditions.
Description
The utility model relates to a kind of air cushion-belt conveyer, belongs to the gas cell device with the air cushion supporting belt.
The air chamber structure of domestic and international existing air cushion-belt conveyer mostly adopts steel plate to be welded into the case structure of circular arc dish rooved face, places the load-transfer device on the dish groove to be supported by pressure air film (air cushion) during work.Its shortcoming is that the air chamber welding deformation is big, dish flute profile position tolerance is difficult to reach, be not easy to form the planar air cushion of satisfactory even circular arc, always there is local friction with load-transfer device, and the material end that unavoidably enters under the load-transfer device in the work, earth etc. also block pore easily, running resistance is increased, and the advantage of air cushioning machine can not finely embody.
The purpose of this utility model provides a kind of air chamber structure device of air film conveyer.This device adopts " case structure of circular arc fin top board ", is welded into a solar term chamber unit body jointly by top board 6, casing 8, gusset 7 and connecting panel 9, the middle osed top air flue 4 that forms.Have air gate 5 on the top board 6, the air inlet pipe 11 on the casing 8 is with blower fan 12 and air flue 4 UNICOMs.Air chamber is connected into an integral body by connecting panel 9 usefulness bolts 10 each other by support 14 and crossbeam 13 supportings.Supporting to top set's load-transfer device 1 and material 2 only is four vertical circular arc fins that are on the same circle, supporting to inferior division load-transfer device 1 only is two circular arc fins that are on the same horizontal surface, the rigidity that mainly has by load-transfer device self from sky of other parts.Such air chamber structure is to the good airproof performance of air, and pressure is set up easily, and is big to the application force of load-transfer device 1, pressure air from the supporting fin to continuously outflow formed wire air cushion 3 effective, conveyer operation friction drag is little.
Principle of work of the present utility model is:
Before the work, load-transfer device 1 is under deadweight and material 2 effect heavily, overlay respectively on four of upper and lower branch air chamber top board 6 and two circular arc fins, owing to have sealing to guarantee along the conveyer at both ends between air chamber top and the load-transfer device, thereby below load-transfer device 1, just form leak free folder cavity space (air cavity).During work, high pressure centrifugal ventilator 12 is delivered to air in the air flue 4 of air chamber middle part by air inlet pipe 11, enters in the above-mentioned air cavity by the pore 5 on air flue 4 top boards 6.Along with constantly entering of air, the air cavity inner air pressure improves constantly.When the pressure on acting on load-transfer device 1 payload space equaled the total force of load-transfer device 1 and material 2, pressure air was about to load-transfer device 1 and floats together with the material on it 2, and air is overflowed between load-transfer device 1 and air chamber circular arc fin, formed air cushion 3.When air leakage amount and suction quantity are close to when equating, load-transfer device 1 (and material 2) float the state that is in relative equilibrium.Because the continuous inflow of pressure air just forms one deck pressure stable air film (air cushion 3) between load-transfer device 1 and air chamber circular arc fin, head roll drives load-transfer device 1 operation that floats on air cushion and the pressure air, realizes material 3 conveyings.
The utility model has the advantages that:
1, rational in infrastructure, top board circular arc fin time processing is shaped, and interchangeability is good, and manufacturing process is simple, and cost is low, and rigidity is big, and weld seam is few, and welding deformation is little.
2, connecting panel adopts the monoblock steel plate structure, and air chamber connection place leak tightness is improved.
3, load-transfer device and air chamber top board area of contact are few, tight-closed, the load-transfer device that has certain rigidity during work under the pressure air effect, float lose heart in, the fin place of the air chamber top board of carrying in original supporting 6 just forms respond well air cushion 3.
4, load-transfer device 1 width is greater than air chamber two-side supporting fin width, and material 2 is difficult for entering pore 5, not plug-hole, not laying dust, not the grinding belt limit, pollution is little, noise is low.
5, load-transfer device 1 directly is not pressed on the air gate 5 of air chamber top board 6, and intake air restriction is little, is easy to pressure and sets up and form air cushion 3 supportings, and load starting is easy.
Accompanying drawing 1 is the transversal surface cutaway view of this this utility model.
Embodiment:
As shown in Figure 1, load-transfer device 1 (and go up material 2) places respectively on four of upper and lower branch air chamber and the two circular arc fins, welding forms osed top air flue 4 in the middle of the air chamber, have air gate 5 in the middle of the air flue 4 top top boards 6, upper and lower branch air chamber is welded into a solar term chamber unit body by top board 6, casing 8, connecting panel 9 and gusset 7, air chamber links up by connecting panel 9 with bolt 10 each other, between accompany packing seal, 13 supportings are connected the empty device of whole gas with crossbeam by support 14.
During work, the air that comes out from blower fan 12 enters the air flue 4 by air inlet pipe 11, enter load-transfer device 1 below by the air gate on the top board 65, after being obstructed load-transfer device 1 and material 2 are floated, formation air cushion 3 loses heart at air chamber top board 6 fin places, head roll drives load-transfer device 1 operation that floats on pressure air and the air cushion 3, realizes material 2 conveyings.
