Referring to fig. 1 to 3, an embodiment of the present invention provides a sealing structure of a material guiding chute of a coal belt conveyor, including a supporting frame 11, a material guiding chute body 12, a dust-blocking curtain 13, a partition plate 14, a dry fog nozzle 15, a clamper 16 and an anti-overflow apron 17; wherein the content of the first and second substances,
the guide chute body 12 is fixedly arranged on the support frame 11, is positioned above the conveying belt 18, and comprises grid lining plates 22 arranged on two sides above the conveying belt 18 and a pointed top 21 arranged at the top of the two grid lining plates 22;
the dust blocking curtains 13 are arranged in multiple ways, and the multiple dust blocking curtains 13 are arranged between the two grating lining plates 22 along the transmission direction of the conveying belt 18;
the partition plates 14 are arranged in the sharp tops 21, and a plurality of partition plates 14 are arranged between the adjacent dust blocking curtains 13 in a one-to-one correspondence manner;
the dry fog nozzles 15 are symmetrically arranged at two sides in the pointed top 21 and are positioned at one side of the partition plate 14 close to the transmission tail end of the conveying belt 18;
the clamp 16 is fixedly arranged on the outer side of the grating lining plate 22;
the anti-overflow skirtboard 17 is arranged at the bottom end of the material guide groove body 12 and comprises an inner side skirtboard 71 arranged at the bottom end of the grating lining board 22 and an outer side skirtboard 17 fixedly arranged on the clamper 16.
In this embodiment, the moment the coal flow falls on the conveyor belt 18 creates a significant air flow, creating induced wind, which entrains a significant amount of soot.
A plurality of dust-blocking curtains 13 are arranged between grid lining plates 22 of the material guide groove body 12, a plurality of partition plates 14 are arranged in the sharp top 21, the dust-blocking curtains 13 and the partition plates 14 are arranged in a staggered mode to form a labyrinth type flow guide channel shown as a curve in fig. 2, the linear motion of air flow is avoided, the path of the air flow along the coal flow direction is increased, the air flow running speed is reduced, and smoke dust is separated from air gradually and is precipitated in the material guide groove body 12. Adopt labyrinth's water conservancy diversion structure, prolonged the smoke and dust route, realized suppressing dirt through the mode that the smoke and dust congeals the dirt passively, initiatively fall the dust at the flow in-process, cooperate dry fog dust fall again, can prevent effectively that the smoke and dust from spilling over from the export of guiding gutter body 12, it is splendid to suppress dirt effect.
The larger the instantaneous flow rate of the coal flow falling on the conveyor belt 18 is, the larger the induced air volume entering the baffle box body 12 is, and the larger the cross section occupied by the coal flow in the baffle box body 12 is, and the smaller the cross section through which the dust-containing air flow can pass is, the larger the air pressure formed by the induced air in the baffle box body 12 is. In order to ensure that the induced wind has enough passing section, the top plate of the guide chute body 12 is changed from the original flat top to the sharp top 21, the height is increased, and the section area of the guide chute body 12 is increased by 50 percent compared with the original area. After the improvement, the air pressure in the material guide groove body 12 is obviously reduced, and the dust suppression effect is further improved.
In some embodiments, the partition plates 14 are provided with vent holes, and the vent holes of the adjacent partition plates 14 are arranged on different sides, that is, the vent hole of one partition plate 14 is arranged on the left side, and the vent hole of the partition plate 14 adjacent to the vent hole is arranged on the right side. An S-shaped airflow channel is formed in the tip 21 along the horizontal direction and is matched with the S-shaped airflow channel formed by the partition plate 14 and the dust blocking curtain 13 in the vertical direction to form flow division and pressure reduction, and the dust suppression effect is improved. Meanwhile, a small amount of smoke dust passes through the airflow channel at the top, and the dust falling effect of the dry fog nozzle 15 on the smoke dust is better.
In a preferred embodiment, as shown in fig. 1 and 3, the distance between the inner skirt plate 71 and the conveyor belt 18 is 1-2mm, and the small gap of the inner skirt plate 71 is arranged, so that impact of coal particles on the outer skirt plate 72 in the blanking process can be avoided, and the phenomena of coal sprinkling and dust overflow can not be caused; the outboard skirt 72 is a double Y-shaped spill skirt, the outboard skirt 72 being in close contact with the top surface of the conveyor belt 18. The three-layer anti-overflow structure is formed, the sealing effect is good, and the smoke dust can be effectively prevented from overflowing.
In a preferred embodiment, the outboard skirt 72 is made of a material having a lower wear resistance than the conveyor belt 18. The wear-resisting property of the outer skirt board 72 made of the novel wear-resisting material is lower than that of the conveying belt 18 made of the rubber material, so that the process of contacting with the conveying belt 18 can be ensured, the surface wear of the conveying belt 18 can not be caused, the anti-dust-overflow board can be tightly attached to the conveying belt 18, and the functions of dust suppression and anti-spilling can be ensured.
In a preferred embodiment, the tip 21 is formed with a viewing hole, and an openable sealing cover is installed on the viewing hole, and the interior of the dry mist sprayer 15 and the material guide chute body 12 can be checked by opening the sealing cover.
