Abstract

The invention discloses a device for cleaning frozen coal on the surface of a belt, which comprises a stripping mechanism and a cleaning mechanism, wherein the cleaning mechanism is positioned at the rear of the stripping mechanism, and the stripping mechanism consists of a spiral roller (2), a spiral roller support (1), a spiral roller bearing (5), a supporting roller (3), a supporting roller support (12), a supporting roller bearing (4), a compaction adjusting mechanism support (6), a screw rod (7), a nut sliding block (8), a limiting shaft sleeve (10) and a spiral roller support connecting bearing (9). The cleaning mechanism consists of a scraper (17), a scraper bracket (14), a bracket connecting rod mechanism (15), an electrohydraulic push rod (16) and a scraper supporting idler (18). According to the invention, when the belt (11) runs, the spiral roller (2) and the supporting roller (3) are driven to passively rotate, so that frozen coal dust attached to the surface of the belt can be effectively stripped off and transferred to the ground on two sides of the belt through the cleaning mechanism, and the belt is prevented from being bulged or even damaged due to adhesion to the steering guide roller.

Description

Device for cleaning frozen and adhered coal on surface of belt
Technical Field
The invention relates to a device for cleaning frozen and adhered coal on the surface of a belt.
Background
In winter in the north, normally, the outdoor air temperature is between minus 10 ℃ and 30 ℃, when warm coal discharged by the dumper enters a dry coal shed, a section of coal conveying belt positioned outdoors is required to pass, when the warm coal is transported, a part of coal dust is always remained and frozen and stuck on a belt working surface, the part of frozen and stuck coal dust enters a belt conveyor roller, a carrier roller or a belt deflection-adjusting bracket revolving bearing, the damage of equipment is accelerated, and particularly, the belt bulge is caused when the guide roller is accumulated, and the belt is damaged seriously. The existing commonly used belt cleaner is of a scraping plate type or a threaded roller type, the installation positions are all on the return path of the belt, and the disadvantage is that the problem that the rollers in front of the cleaning device are stuck with coal cannot be solved between the rollers at the two ends of the belt conveyor, and the cleaned coal dust is difficult to clean. In addition, the conventional scraper type belt cleaner at present uses a spring tensioning mechanism, the tensioning force can not clean frozen and adhered coal on the surface of the belt, and the scraper made of high polymer materials is easy to wear and has short service life.
In summary, how to improve the structure and the installation position of the belt cleaning device is an urgent issue for solving the problem of frozen coal on the surface of the northern belt conveyor.

The apex angle of the scraper bracket (14) is 90-135 degrees.
The central point of the axial direction of the spiral roller (2) is taken as a demarcation point, one side of the spiral roller (2) is provided with a left-handed spiral belt, the other side of the spiral roller (2) is provided with a right-handed spiral belt, and the helix angle of the spiral roller (2) is larger than 30 degrees and smaller than 70 degrees.
The working principle of the invention is as follows:
the invention designs the stripping mechanism with the thread roller, the distance between the thread roller and the belt can be adjusted through the compaction adjusting mechanism, the supporting roller is arranged below the belt to support the belt, the position is parallel to the thread roller, the thread roller can be effectively pressed on the surface of the belt by the structure, the coal dust frozen and stuck on the surface of the belt is stripped and loosened through the transverse displacement of the thread blade on the thread roller in the process of the belt operation, and the belt is removed when the belt passes through the later cleaning mechanism.
The invention has the technical effects that:
in order to enable the thread roller to be effectively pressed on the surface of the belt, the invention designs a pressing adjustment mechanism, the mechanism consists of a screw rod, a nut sliding block and a line position shaft sleeve, the belt can be conveniently pressed by rotating a handle, so that coal dust frozen and stuck on the surface of the belt can be thoroughly removed, and the traditional scraper type belt cleaner uses a spring tensioning mechanism to adjust the pressing force and distance between a scraper and the surface of the belt, and basically does not work corresponding to the frozen and stuck coal.
When the spiral roller 2 is dragged by the belt to rotate, the frozen and stuck coal dust is stripped by the screw blades and pushed to two sides, and when the coal dust stripped from the surface of the belt hits the scraping plate 17 on the scraping plate support 14 along with the forward running of the belt, the coal dust can slide to the ground on two sides of the belt along with the scraping plate, so that cleaning work is realized. The helix angle of the spiral roller 2 is selected to be in the range of 30-70 degrees, and the transverse scraping thrust generated by the thread blades is beneficial to stripping of frozen and stuck coal dust and reducing abrasion to a belt. The apex angle of the scraper 17 is selected to be in the range of 90-135 degrees, which is favorable for the turning conveying of the stripped pulverized coal and reduces the friction resistance.
