Description

Sweeper capable of improving sweeping effect of conveying belt

Technical Field

The utility model relates to a sweeper capable of improving sweeping effect of a conveying belt.

Background

In a thermal power plant, a belt conveyor sweeper is an indispensable working part of a belt conveyor in the working process, and can timely sweep materials attached to the surface of a belt. The conventional 2 66-ten thousand thermal generator sets of the elm transverse power plant of the elm transverse coal electric finite duty company of Shaanxi Hua adopt belt conveyors to convey all the coal in the process of coal transportation. The belt conveyor belt is worn and aged seriously after the unit of the elm transverse power plant is put into production for a long time, a plurality of belts are bonded by using the repairing strips, the bonded repairing strips are scraped by a sweeper hard scraper in the operation process to influence the operation of the belts, and the clearance between the sweeper scraper and the bonding surface of the working surface of the belt is adjusted greatly, so that part of sweepers lose the effect. In addition, in the transverse electric power plant of elm, the coal humidity and viscosity are high in recent years, so that the coal is easily adhered to a belt in the conveying process, accumulated coal adhered to the working surface of the belt cannot be completely cleaned up through a cleaner installed at present, and under the condition of double-machine heavy-load operation, the accumulated coal below a roller is seriously increased in diameter to aggravate the abrasion of the roller to the belt, so that the belt is deviated, the coal is scattered, and the field environment is polluted. Due to the fact that the coal feeding task is heavy during a large load period, the belt runs for a long time, too much coal deposit below the roller cannot be timely cleaned, the belt and the coal deposit generate heat due to long-time friction, great fire hazard is caused, and safe and stable running of a coal conveying area is seriously affected. In the double-machine operation process, the accumulated coal at the head of the belt roller needs to be cleaned two times or three times a day, so that the working strength of the operation cleaning personnel is greatly increased, and the labor cost is increased. Therefore, the originally designed belt sweeper has certain defects and shortcomings in the use process of the unit in the later production period, and the optimization and the modification of the sweeper are not slow in time.

Disclosure of Invention

The utility model aims to provide a sweeper capable of improving the sweeping effect of a conveying belt.

The above purpose is realized by the following technical scheme:

the utility model provides an improve sweeper that conveyor belt cleaned effect which constitutes includes: sweeper scraper blade and anti-overflow skirtboard, the sweeper scraper blade with anti-overflow skirtboard fixed connection, the sweeper scraper blade with anti-overflow skirtboard on equidistant four jacks that the diameter is the same of diameter of having seted up respectively, and the diameter of jack is 8mm, the interval that the jack was seted up to sweeper scraper blade and anti-overflow skirtboard is the same, and the jack on the sweeper scraper blade and the jack on the anti-overflow skirtboard insert wear screw, fix the one side in sweeper scraper blade and belt working face contact through wear screw anti-overflow skirtboard.

The sweeper capable of improving the sweeping effect of the conveying belt is characterized in that the sweeper scraper and the anti-overflow apron plate are of rectangular structures with the same length and different widths, and the anti-overflow apron plate is made of polyurethane.

The sweeper for improving the sweeping effect of the conveying belt is characterized in that a sweeper scraping plate is fixed on a shaft body, two ends of the shaft body are connected with supports on two sides of the belt conveyor, the belt is connected with a roller, and the roller is connected with a bearing seat through a rotating shaft.

The utility model has the beneficial effects that:

1. the utility model optimizes the use effect of the sweeper at the head of the conveying belt under the working conditions that the combination surface of the sweeper and the belt cannot be adjusted too tightly after the belt is adhered by the repairing strip and the water content of coal is large. The coal belt has the advantages that the fire hazard caused by excessive coal accumulated under the roller at the head of the coal conveying belt is prevented, the service life of the belt is shortened, the frequency of manually cleaning the accumulated coal is reduced, and the labor cost is reduced.

The utility model solves the technical problem that the sweeper cannot meet the field use requirement under the working conditions of more aged and repaired coal conveying belts of the elm transverse power plant and more coal moisture. The method mainly comprises the steps of punching four holes with the diameter of 8mm on the existing sweeper scraper at equal intervals, selecting a polyurethane anti-overflow apron plate with the same length as the sweeper scraper and punching four holes with the diameter of 8mm at equal intervals, wherein the hole spacing distances of the sweeper scraper and the anti-overflow apron plate are the same. And (3) fixing the anti-overflow apron board on the side of the sweeper scraper contacting with the working surface of the belt by using wear-resistant screws. Due to the characteristics of wear resistance and strong flexibility of the anti-overflow apron board, the phenomenon that the repair strip used for bonding the belt is scraped up can not be caused after the additionally arranged anti-overflow apron board is in close contact with the working surface of the belt by adjusting the adjusting device of the cleaner. When the sweeper scraper blade after reforming transform contacted with the belt working face, the anti-overflow skirtboard played the cushioning effect, made the inseparable laminating of scraper blade on the belt working face, improved by a wide margin the effect that the coal adhered to the working face cleaned under the great operating mode of coming coal moisture to ingenious solution the above-mentioned problem that exists.

According to the utility model, the anti-overflow apron board is additionally arranged on the original sweeper scraper, so that the sweeping effect of the sweeper is obviously improved, the coal accumulation rate of the roller under the working condition of double-machine heavy load operation is reduced, the labor intensity of workers is reduced, and the labor cost is saved. The problem that the cleaning effect of the sweeper is not influenced and the belt repairing strip is not scraped by a hard scraper of the sweeper is solved, and a better guarantee is provided for the safe and stable operation of the coal conveying belt.

The utility model can efficiently and quickly complete the transformation work in a short time, does not influence the operation of equipment, reduces the cost of replacing the novel sweeper and reduces the maintenance cost. Meanwhile, the possibility of fire hazard of the belt is reduced, the belt deviation phenomenon is reduced, the belt operation efficiency is improved, and the enterprise production benefit is indirectly improved. After long-time observation after transformation, the sweeper has obvious sweeping effect, is widely used, can be applied to a plurality of fields, and is easy to popularize.
