The utility model content
Problem to be solved in the utility model provides a kind of material conveyor negative pressure dust control device.Use this material conveyor negative pressure dust control device, can avoid environmental pollution, help operator's health.
For addressing the above problem, the utility model is taked following scheme:
Material conveyor negative pressure dust control device of the present utility model comprises belt conveyor, and there is deflector chute the belt conveyor top, and two through holes are arranged on the deflector chute, and this two through hole place is equipped with feeder hopper and dust-contained airflow disconnector respectively; It is characterized in that said deflector chute is made of two baffle plates under loam cake and the loam cake; Wherein, the top of two baffle plates is the sealing shape and is connected on the lower surface both sides of loam cake, two of the load-transfer devices that their bottom is in belt conveyor go up in the alices and and two of load-transfer devices go up between alices and leave the gap.Covered horizontal groove in contiguous discharging opening place, covered support in the horizontal groove place, the support below has dust board, the top of dust board to be suspended on the support and horizontal groove passes near the load-transfer device top in its bottom; In the gap between the inside face of two last alices of the bottom of two baffle plates and load-transfer device interpolation eversion type double-layer seal bar is arranged.
Take such scheme, have the following advantages:
Because material conveyor negative pressure dust control device of the present utility model, its deflector chute is made of two baffle plates under loam cake and the loam cake.The top of two baffle plates is the sealing shape and is connected on the lower surface both sides of loam cake, two of the load-transfer devices that their bottom is in belt conveyor go up in the alices and and two of load-transfer devices go up between alices and leave the gap.And on two of the bottom of two baffle plates and load-transfer devices, be provided with the two-layer sealing band of interpolation eversion type in the gap between the inside face of alice.Make in material conveying process, a large amount of dust be blocked on belt carry put in, dust can outwards not spray.Not only avoided environmental pollution, also to operator's healthy and beneficial.In addition, covered horizontal groove in contiguous discharging opening place, covered support in the horizontal groove place, there is dust board the support below, the top of dust board is suspended on the support and horizontal groove passes near the load-transfer device top in its bottom, has increased again to prevent the defence line that dust overflows together.Again on the one hand, owing to be provided with spraying mechanism at the discharging opening place of loam cake, the nozzle of this spraying mechanism is towards the below and aim at discharging opening, and by spraying mechanism, the dust that produces owing to the drop reason during with blanking is eliminated in bud.This shows that adopt material conveyor negative pressure dust control device of the present utility model, dust can outwards not spray, and not only can not bring pollution to environment, also to operator's healthy and beneficial.
Description of drawings
