Abstract
The utility model discloses a pulverized coal transfer dust suppression device which comprises a hopper. A feeding port and a discharge port are arranged on the hopper, a feed guide mechanism of more than two layers is arranged between the feeding port and the discharge port from up to down in the hopper, each layer of feed guide mechanism comprises a plurality of feed guide pieces arranged at intervals, one end along the length direction of each feed guide piece is connected with one side of the inner wall of the hopper, and the other end along the length direction of each feed guide piece is connected with the other side of the inner wall of the hopper, each feed guide piece comprises two side parts, the two side parts are connected at the top and form an angle larger than zero degree, and the outer walls of the two side parts are planes. In each two adjacent layers of feed guide mechanism, the top end of each feed guide piece on the lower layer are located below the area between each two feed guide pieces on the upper layer. When the pulverized coal transfer dust suppression device is used, pulverized coal transferred from upper reach equipment enters into the hopper, passes through each layer of feed guide mechanism, naturally forms a layer of feed curtain to fall down between each two layers and is sent to lower reach equipment through the discharge port. The raised dust can be reduced, and less dust transfer of the pulverized coal is achieved.
Description
Technical field
The utility model relates to Coal dressing accessory equipment technical field, and particularly a kind of coal dust is reprinted dust-arrest device.
Background technology
Brown coal need to be reprinted an other equipment from an equipment at production process, for example broken after after belt feeder, the screening to belt feeder, belt feeder to belt feeder, belt feeder to screening or disintegrating apparatus etc.In loading chute, owing to there being diff-H, when falling, coal dust can produce a large amount of airborne dusts, and one causes waste, and two cause environmental pollution, so that whole work under bad environment, affect the health of operating personal.
This shows how a kind of dust-arrest device is provided, can be applied to prevent airborne dust in the brown coal loading chute, avoid contaminated environment, this is the present technical issues that need to address in this area.
The utility model content
The purpose of this utility model is, provides a kind of coal dust to reprint dust-arrest device, can suppress the airborne dust problem in the coal dust loading chute.
For solving above technical matters, the technical solution of the utility model is:
A kind of coal dust is reprinted dust-arrest device, comprise hopper, described hopper is provided with inlet point and discharging opening, between the inlet point of hopper inside and discharging opening, from top to bottom be provided with two-layer above material guide mechanism, seek material mechanism for every layer and comprise the material guiding parts that a plurality of intervals arrange, described material guiding parts is connected with inwall one side of hopper along its length direction one end, the other end is connected with the inwall opposite side of hopper, described material guiding parts comprises two sidepieces, two sidepieces connect at the top and become angle greater than zero degree, the outer wall of two sidepieces is the plane, and in the adjacent two layers material guide mechanism, the top of material guiding parts is in the upper strata below the zone between two material guiding parts in the lower floor.
Preferably, be positioned at the identical distance setting in each material guiding parts interval of same layer.
Preferably, each material guiding parts that is positioned at same layer be arranged in parallel.
Preferably, two of described material guiding parts sidepieces are straight plate body.
Preferably, two sidepieces are 60 degree～120 degree at the angle of top one-tenth.
Preferably, two sidepieces are 80 degree～100 degree at the angle of top one-tenth.
Preferably, each layer material guide mechanism interval evenly arranges.
Preferably, the base portion of described hopper is enclosed to connect by four plate bodys that are inverted trapezoidal and is formed.
Compared with prior art, coal dust of the present utility model is reprinted dust-arrest device, comprise hopper, described hopper is provided with inlet point and discharging opening, between the inlet point of hopper inside and discharging opening, from top to bottom be provided with two-layer above material guide mechanism, every layer of material guide mechanism comprises the material guiding parts that a plurality of intervals arrange, described material guiding parts is connected with inwall one side of hopper along its length direction one end, the other end is connected with the opposite side of the inwall of hopper, described material guiding parts comprises two sidepieces, two sidepieces connect at the top and become angle greater than zero degree, the outer wall of two sidepieces is the plane, in the adjacent two layers material guide mechanism, the top of the material guiding parts of lower floor is in the upper strata below the zone between two material guiding parts, thereby when being arranged between two equipment, the coal dust that transfers from upstream equipment enters into hopper, through every layer of material guide mechanism, between each layer, coal dust can fall by self-assembling formation one layered material curtain, finally by delivering to upstream device by discharging opening, thereby can reduce airborne dust, realize that few dirt of coal dust is reprinted, reduce the pollution of environment and the loss of coal dust.
