Description

Belt conveyor tail redirection roller cleaning device

technical field

The utility model relates to a cleaning device, in particular to a cleaning device for a reversing roller at the tail of a belt conveyor.

Background technique

Coal, coke, ore and other raw materials used in ironworks are transferred to coke ovens or blast furnaces through belt conveyors. During the transportation process, the tail of the belt is often diverted to the drum to wrap the material, resulting in belt deviation and scratches Belt and other problems, so it is necessary to remove the material attached to the surface of the rear redirecting roller at any time during the conveying process.

At present, the conventional method of removing material on the surface of the rear reversing drum is to install an empty segment cleaner on the return belt of the belt conveyor close to the rear reversing drum. Due to the large vibration of the belt during operation and the distance between the return belt and the ground Small, the remaining material after cleaning needs to be removed manually in time, otherwise it will cause material accumulation, and the accumulated material will be brought into the tail drum after exceeding the height of the return belt from the ground. At the same time, because the empty section cleaner used is a V-shaped cleaner, it is very easy to scratch the belt when hard materials or sundries are stuck on the tip of the V-shaped cleaner.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figures 1 to 3, the belt conveyor tail redirecting roller cleaning device of the present invention includes a scraper plate 1 and a herringbone guide groove 2; Below the lower end of the plate 1, the upper end of the scraper 1 is in contact with the tail redirection drum 3 of the belt conveyor, and the material scraped by the scraper 1 from the tail redirection drum 3 of the belt conveyor goes along The scraper 1 falls into the herringbone guide groove 2; the length of the scraper 1 is greater than or equal to the length of the redirection drum 3 at the tail of the belt conveyor, and the projection of the herringbone guide groove 2 on the horizontal plane Length>the projected length of the redirection drum 3 at the tail of the belt conveyor on the horizontal plane. The upper end of the scraper 1 is in contact with the reversing drum 3 at the tail of the belt conveyor, and the material scraped off by the scraper 1 from the reversing drum 3 at the tail of the belt conveyor falls into the place along the scraper 1 In the herringbone guide trough 2, when the belt conveyor tail redirection drum 3 rotates clockwise, the scraper 1 is arranged on the right side of the belt conveyor tail redirection drum 3, as shown in Figure 3; The reversing drum 3 at the tail of the belt conveyor rotates counterclockwise, and the scraper 1 is arranged on the left side of the reversing drum 3 at the tail of the belt conveyor. The length of the scraper 1 ≥ the length of the belt conveyor tail redirecting drum 3 makes the scraper 1 contact any position on the surface of the belt conveyor tail redirecting drum 3, so that the belt conveyor tail can be All the materials on the reversing drum 3 are removed. The projected length of the herringbone trough 2 on the horizontal plane>the projected length of the belt conveyor tail redirecting roller 3 on the horizontal plane, so that the material falling into the herringbone chute 2 flows along the chevron trough 2 Flow to both sides of the belt rack, so that the material is accumulated on both sides of the belt rack, the accumulated material will not be brought into the tail drum by the return belt, and the material is accumulated on both sides of the belt rack, on the belt It can be cleaned without stopping the machine, which is convenient for removing materials and can prevent safety accidents.

During the conveying process, due to factors such as belt deviation or excessive material flow, some materials are spilled onto the non-working surface of the return belt, and after arriving at the tail, they are wrapped on the surface of the rear redirection drum 3 of the belt conveyor. The belt of the utility model is adopted. When the cleaning device at the tail of the belt conveyor is used to clean the material on the surface of the drum 3 at the tail of the belt conveyor, it rotates with the drum 3 at the tail of the belt conveyor. The upper end of the plate 1 touches, and the material attached to the surface of the reversing drum 3 at the tail of the belt conveyor is scraped off by the scraper 1, and the material scraped off by the scraper 1 flows into the lower herringbone guide along the inclined direction of the scraper 1. In the material trough 2, the material flows to the safety zone on both sides of the belt frame through the herringbone guide trough 2, and the material can be cleaned without stopping the belt conveyor, which is convenient for removing the material, and if it is not cleared in time, it will accumulate on the belt conveyor The materials on both sides of the rack will not be brought into the tail drum by the return belt.

As a preferred embodiment, the upper end of the scraper 1 is in contact with the upper half of the redirection drum 3 at the tail of the belt conveyor. In this way, it is possible to prevent the material attached to the surface of the reversing drum 3 at the tail of the belt conveyor from being thrown off under the action of centrifugal force when it has not rotated to the position of the upper end of the scraper 1, which is not conducive to the collection of materials.

In order to reduce the friction between the scraper 1 and the reversing drum 3 at the tail of the belt conveyor, and reduce the wear of the scraper 1 on the surface of the reversing drum 3 at the tail of the belt conveyor, as a preferred embodiment, the scraper The upper end of the material plate 1 is tangent to the reversing drum 3 at the tail end of the belt conveyor.

In order to facilitate the scraped material to fall into the herringbone guide groove 2 along the scraper 1 , as a preferred embodiment, the angle B between the scraper 1 and the horizontal plane 4 is 45°.

As one of the implementation manners, the apex angle A of the herringbone trough 2 is 120°.

As a preferred embodiment, the scraper 1 and the herringbone guide groove 2 are made of iron plates. The iron plate is low in cost, easy to process, not easy to deform, and durable.

If the scraper is too thick, it is not conducive to scraping the material clean, and if it is too thin, it will be easily deformed and not durable. As a preferred embodiment, the thickness of the scraper 1 is 3 mm.
