Problems solved by technology

There are also multi-points to increase dust removal equipment or sprinkler devices to reduce induced wind and dust, which are not very ideal, especially at transfer points with large belt speed and high drop, dust is even more difficult to control

Embodiment 1

[0036] like Figure 1-3 As shown, the embodiment of the present invention discloses a dual-channel dust-suppressing guide chute for air-material separation, including: multiple pairs of pillars 1, and each pair of pillars 1 is symmetrically installed on the middle frame of the belt conveyor on site, To support the entire chute; the top shield 2, the top shield 2 is installed on the pillar 1, the top shield 2 includes two symmetrically arranged side plates 2.1 and a top cover erected above the side plates 2.2; sealing assembly 3, the sealing assembly 3 is used to connect the top shield 2 and the belt conveyor to form a sealed material guide channel between the top shield 2 and the belt upper surface of the belt conveyor 3.1, the sealing assembly 3 includes a holder, an anti-overflow skirt and a liner arranged on the outside of the side plate 2.1, which are used to block and seal the material in the flow passage, and the anti-overflow skirt is made of polyurethane wear-resistant...

Embodiment 2

[0044] The difference between this embodiment and Embodiment 1 is that in each attenuation part, two adjacent baffles 6 are arc-shaped baffles, and the arc-shaped openings of the two baffles are arranged in opposite directions, and the The induced wind performs vortex attenuation movement under the action of the arc-shaped baffle, which avoids dust caused by fine materials brought up by the change of wind direction. After the induced wind passes through multiple vortexes, it reaches the filter dust suppression air curtain 8, and the induced wind after the reduced energy is filtered and discharged through the air primary effect metal filter screen on the filter dust suppression air curtain 8.

Embodiment 3

[0046] The difference between this embodiment and Embodiment 1 is that each baffle 6 is only fixedly connected to one of the two side plates, the top cover and the diverter plate, and a plurality of baffles 6 are in the upper channel 3.11. The radial parts are staggered to form a plurality of communicating attenuation channels.

Abstract

The invention provides a dual-channel dust-suppressing guide chute for air and material separation, comprising: multiple pairs of pillars, top shields arranged on the pillars, seals for connecting the top shields and the belt conveyor assembly and a splitter plate, the splitter plate is arranged on the top shield, used to divide the guide channel into an upper channel and a lower channel, and the lower surface of one end of the feed port of the belt conveyor is provided with a resistance Air curtain, by rationally using the structural space of the material guide trough, the interior of the material guide trough is designed as a double-channel structure, which separates the wind and the material into separate channels, reduces the contact between the induced wind and the material, and reduces dust; the material channel is in high-speed motion Contact with less air in the channel, resulting in less dust, through the blocking and attenuation of the wind blocking curtain, the dust diffusion and generation can be effectively suppressed; the induced air channel is designed with a rotary vane, so that the induced wind rotates in the rotary vane, attenuating the induced wind speed, and at the same time There is no contact between the wind and the material, and the rotation will not stir up dust.

Description

technical field [0001] The invention relates to the technical field of belt conveyor transfer of bulk solid materials such as power stations, ports, and mines, and in particular to a dual-channel dust suppression guide chute used for wind and material separation in bulk material conveying systems. Background technique [0002] Belt conveyor is a commonly used material conveying equipment. It can be widely used in metallurgy, coal, transportation, electric power, building materials, chemical industry, light industry, grain and machinery industries. It is an important tool for conveying coal in electric power enterprises. Transportation Equipment. Among them, the function of the guide trough is to be installed at the material receiving place of the belt conveyor to restrain the material from falling out, and its reliable operation is a necessary condition for the normal operation of the belt conveyor. The guide trough is installed in each part of the belt conveyor. Although t...
