Description

A kind of air cushion-belt conveyer air chamber connection structure

Technical field

The utility model relates to a kind of conveyer, relates in particular to a kind of air cushion-belt conveyer air chamber connection structure, belongs to the mechanical transport field.

Background technology

In the mechanical transport field, the band conveyor tool is that one of equipment that arrives commonly used is gone up in industry, and especially industry and place all can be used at building materials, chemical industry, mine, harbour, warehouse, station, goods yard, grain distribution station etc., and it is a kind of extensive general-duty conveying machinery.

Air cushion-belt conveyer is the international and domestic new continuous load transfer device that grows up of the eighties; Be mainly used in the transportation of bulk material such as sand, stone, coal, iron sand, cement, clay etc., also can be used for the conveying of member such as article such as bagged cement, grain.Its principle of work is: the pressure air from blowing engine gets into gas tank, gets between panel and the load-transfer device together with material through the pore on the gas tank panel.Select under the air cushion parameter condition correct, this place can form air cushion, holds up load-transfer device and material.When load-transfer device moves with certain speed, between gas tank panel and load-transfer device lower surface, just form gas friction, the resistance of pull-over gear load-transfer device is greatly reduced, power draw greatly reduces, and energy-saving effect is remarkable.With the carrying roller machine mutually this, energy-conservation more than 25%.Secondly, because of resistance is little, and air cushion is continuous along throughput direction, and load-transfer device is stable and do not jolt, so delivery speed can greatly improve, conveying efficiency can be enhanced about more than once.When deviation phenomenon occurs because the air-cushion pressure self-regulation effect, be limited in the belt deflection amount very among a small circle in, general running deviation value only be half of carrying roller machine.Because carrying roller quantity reduces about 90%, maintenance load and corresponding expense reduce more than 60%.

Present Air-cushion Type Belt Conveyer both domestic and external is owing to can't solve air chamber and be connected with dish the reasonable of groove reasonable the connection with air chamber of air chamber; Basically all adopt the type of attachment of welding, cause on-site installation inconvenient, installation strength is bigger, and setting accuracy is difficult to guarantee, can not be fit to the production and the installation of air chamber in enormous quantities, need destroy soldered when safeguarding and pull down damage air chamber and dish groove, and is maintainable relatively poor.

At present, both at home and abroad for realizing that the air cushion-belt conveyer air chamber structure connects the following method that adopts:

Fig. 1 is an air cushion-belt conveyer air chamber connection structure scheme drawing in the prior art.As shown in Figure 1; Said air cushion-belt conveyer air chamber structure comprise load-transfer device 1, air chamber 2 and with the support 6 of dish groove 4, carrier groove and the air chamber of air chamber 2 welding; Connect between the air chamber that said air chamber 2 is adjacent and adopt welding, the dish groove connection that dish groove 4 is adjacent is adopted welding or is pegged graft.Said load-transfer device 2 forms air film by effluent air in the cutoff port on the dish groove 4 and carries, and material 7 is arranged at the upper surface of said load-transfer device 2.Fig. 2 is the dish groove connection mode of said welding or grafting, all can cause the distortion of dish groove, and it is stable to destroy air film; Cause dish groove 2 bigger, not only increased the operation total drag of equipment, increased energy consumption with the friction coefficient of load-transfer device 2; And whole erection employing welding technique, the on-site installation work amount is big, and the equipment progress is difficult to guarantee; But maintenance interchangeability is relatively poor, has seriously restricted the extensive popularization and the production in enormous quantities of air film conveyer.
