Description

Technical Field

[0001] The utility model relates to the field of material guide troughs, in particular to a material guide trough capable of suppressing dust. Background Art

[0002] The guide trough is mainly used in DT2 series belt conveyors and YM96 series belt conveyors. Installing the guide trough at the receiving part of the belt conveyor can make the materials falling from the hopper concentrate in the middle of the conveyor belt before reaching the belt speed, so as to prevent the materials from being scattered. When transporting powder materials, since the powder materials are fine in particle size, the powder materials will fly during transportation, which will cause a large concentration of dust to spread.

[0003] The Chinese utility model patent with the public document number: CN206871931U discloses a double-sealed anti-dust material guide trough. In this document, the conveyor belt is sealed by a sealing cover in conjunction with an anti-overflow skirt and a wear-resistant liner to prevent dust from leaking out, reduce material losses, and improve the working environment. However, a large amount of powder dust generated during belt conveying will gradually diffuse and accumulate in the internal position of the sealing cover. There is no dust suppression structure in the sealing cover. As the dust concentration gradually increases, it is easy to leak from the outlet and entrance, causing a large concentration of dust pollution at the outlet and entrance, damaging the health of surrounding workers, so improvement is needed.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, a dust suppression assembly 6 is movably installed on the sealing cover 1, and the dust suppression assembly 6 includes a water spray pipe 601, a water collection bin 603, a drainage pipe 604, a water collection box 607, a dirt collection box 608, a water pump 612 and a water outlet pipe 613. The water spray pipe 601 is fixedly connected to the top position of the sealing cover 1, and both ends of the water spray pipe 601 penetrate the sealing cover 1 and extend to the outside position. The water collection bin 603 is fixedly connected to the side walls of the sealing cover 1 on both sides, and the water collection bin 603 is located at the sealing cover. 1, the dust suppression component 6 also includes a water outlet 602, the water outlet 602 is fixedly connected to the two sides of the water spray pipe 601, the drainage pipe 604 is fixedly connected to the sealing cover 1, and the water collecting box 607 is fixedly connected to the two sides of the bracket 3. The dust suppression component 6 also includes a No. 1 flange 606 and a partition plate 605, the No. 1 flange 606 is fixedly connected to the two ends of the water spray pipe 601, and the No. 1 flange 606 is located at the outer side of the sealing cover 1, and the partition plate 605 is fixedly connected to the middle position of the water spray pipe 601. The dust suppression component 6 also includes a No. 2 flange 614. The No. 2 flange 614 is fixedly connected to one end of the outlet pipe 613. The No. 1 flange 606 and the No. 2 flange 614 are fixedly connected by bolts and nuts. The water spray pipe 601 forms a pipe body structure that is not connected to the front and back through the partition plate 605. The front and rear pipe bodies of the water spray pipe 601 respectively receive the liquid in the water collecting tank 607 on both sides and spray it out through the water outlet 602. The water outlet 602 sprays the clean water obliquely and receives the clean water through the water collecting bin 603. The clean water sprayed out in multiple channels forms a dense water curtain structure, which contaminates the lighter powder particles floating in the previous position and drives the particles to move together into the water collecting bin 603. As the drainage pipe 604 is led out, the outer surfaces of the pipe bodies of the drainage pipe 604 and the water spray pipe 601 are fixed to each other with the sealing cover 1 by welding, and the dust inside is treated by dust reduction through the water curtain to reduce the dust concentration.

[0024] like Figure 1 , Figure 2 and Figure 4As shown, the dirt collecting box 608 is movably installed in the water collecting box 607, the water pump 612 is fixedly connected to the side position of the water collecting box 607, and the water pump 612 is fixedly connected to the water spray pipe 601 through the outlet pipe 613. The dust suppression component 6 also includes a filter hole 609, a hanging ear 610 and a water pumping pipe 611. The filter hole 609 is opened at the bottom of the dirt collecting box 608, the hanging ear 610 is fixedly connected to the two sides of the dirt collecting box 608, and the hanging ear 610 is movably installed with the water collecting box 607, and the water pump 611 is fixedly connected to the side position of the water collecting box 607. The dirt collecting box 608 is fixedly connected with the water collecting box 607 through the water extraction pipe 611, and the dirt collecting box 608 is movably installed in the water collecting box 607 through the hanging ear 610. The water extraction pipe 611 is located below the dirt collecting box 608, so as to facilitate the extraction of liquid in the dirt collecting box 608, and intercept and collect the granular powder in the dirt collecting box 608 through the filtering hole 609. When the dirt collecting box 608 needs to be cleaned, the dirt collecting box 608 is lifted out through the hanging ear 610, and the powder particles in the dirt collecting box 608 are directly cleaned, and the clean water is processed by the dirt collecting box 608 to remove the powder particles, and the liquid will not block the subsequent pipelines.

[0025] It should be noted that the utility model is a guide trough for suppressing dust. Water outlets 602 are densely connected on both sides of the water spray pipe 601. The water outlets 602 are inclined downward and point to the water collection bin 603. Both ends of the water spray pipe 601 are connected to the water pump 612 and the water collection tank 607 at both sides through the water outlet pipe 613. The water pump 612 pumps clean water out of the water collection tank 607 and injects it into the water spray pipe 601 through the water outlet pipe 613. The water outlets 602 on both sides of the water spray pipe 601 spray clean water, and the clean water falls into the water collection bin 603. Through the sealed water outlets 602, a water curtain structure is formed at the upper position of the sealing cover 1. When the powder is diffused, the heavier particles will fly to the lower position under the action of gravity, and the lighter particles will diffuse at the upper position. The lighter particles are not easy to fall naturally. When they come into contact with the water curtain, they enter the water collection bin 603 along the water curtain and pass through the connected The drainage pipe 604 flows outward, thereby reducing the dust concentration in the sealing cover 1, and suppressing the dust in the sealing cover 1 to prevent the dust concentration in the sealing cover 1 from being too high and expanding and leaking from the inlet, outlet or weak connection of the belt. The outer end of the drainage pipe 604 points to the dirt collecting box 608 in the water collecting box 607. The clean water enters the water collecting box 607 after passing through the dirt collecting box 608 and is pumped out again by the water pump 612, so that the water body is recycled and a large amount of water resources can be saved. A large number of filtering holes 609 are provided on the bottom surface of the dirt collecting box 608 to filter the clean water flowing out of the drainage pipe 604, so that the powder particles contaminated in the clean water are filtered out and intercepted and collected in the dirt collecting box 608, so that the powder particles are easy to collect. After the clean water flowing out of the drainage pipe 604 is filtered, the powder particles are not easy to block the water pumping pipe 611, the water outlet pipe 613 and other pipes, so that the water body is recycled more smoothly.
