[0001] The utility model relates to the technical field of material conveying belt conveyors, in particular to a frozen layer removing device for a belt conveyor. Background Art

[0002] Belt conveyors are the main equipment for transporting coal mine materials. Due to the cold weather in the northern region and the fact that coal contains more water after being mined, when the coal is placed on the belt during transportation, the water accumulates and easily freezes into a layer of ice containing coal powder on the working surface of the belt. The ice layer easily causes the belt and roller to slip, making it impossible to transport the coal normally. Utility Model Content

DETAILED DESCRIPTION

[0020] See also Figure 1-14A frozen layer removal device for a belt conveyor, comprising an ice-breaking mechanism 10, an ice-removing mechanism 20, and a cleaning mechanism 30; the ice-breaking mechanism 10 comprises an upper roller 11 and a lower roller 12, the upper part of the upper roller 11 is movably connected to a belt conveyor frame, the upper roller 11 moves up and down relative to the frame, the lower part of the lower roller 12 is movably connected to an external foundation, the lower roller 12 moves up and down relative to the foundation, the upper roller 11 is arranged above the belt and contacts the back of the belt, the lower roller 12 is arranged below the belt and contacts the working surface of the belt, a plurality of blade teeth 121 are arranged on the surface of the lower roller 12, and the blade teeth 121 protrude from the surface of the lower roller 12; the ice-removing mechanism 20 is arranged at the rear end of the ice-breaking mechanism 10, and ... 0 includes a scraper 21, one end of which is arranged on an external frame, and the other end is in contact with a working surface of the adhesive tape 100. The cleaning mechanism 30 includes an upper pressure roller 31 and a roller brush 32. The upper pressure roller 31 is pressed on the back of the adhesive tape and is in close contact with the back of the adhesive tape. A connecting component (for example, a chain, through which the movement of the upper pressure roller 31 is transmitted to the roller brush 32, which drives the roller brush 32 to rotate, and the roller brush 32 is suspended on the frame) is arranged between the upper pressure roller 31 and the roller brush 32. The adhesive tape is driven to move by the driving roller, and the high-speed running adhesive tape drives the upper pressure roller 31 to rotate at a high speed, drives the chain to move, and the moving chain drives the roller brush 32 to rotate, and the rotating roller brush 32 cleans the crushed ice on the surface of the adhesive tape.

[0021] Furthermore, an adjustment seat 13 is provided between the upper roller 11 and the frame, and a plurality of upper rollers 11 are connected to the adjustment seat 13, and the upper end of the adjustment seat 13 is connected to the frame. This structure realizes that a plurality of upper rollers 11 are connected into a module by the adjustment seat 13, and then the module is installed under the frame, so that the upper roller 11 is modularly connected to the frame, which is convenient for installation and replacement. A collection box 14 is also provided under the lower roller 12, and a plurality of lower rollers 12 are installed on the box 14. The box 14 is used to receive the broken and fallen ice layer, and a plurality of lower rollers 12 are arranged on the box 14 at intervals, so that the upper roller 11 forms a module, which is convenient for installation and replacement.

[0022] The upper roller 11 is movably connected to the frame, and the lower roller 12 is also movably connected to the base. For example, bolts are arranged between the upper roller 11 and the frame, and between the lower roller 12 and the base, and the height of the upper roller 11 is adjusted by adjusting nuts to achieve pressing down to the tape, or lifting away from the tape.

[0023] Furthermore, the blade teeth 121 are in the shape of thin plates, which are annular structures 122 surrounding the surface of the lower roller 12. The radial direction of the thin plates is the same as the radial direction of the lower roller 12, and adjacent thin plates are arranged at intervals. In this manner, the radial thin plates cut the ice layer into thin strips along the length direction of the tape. Since the tape is long, the ice layer formed by cutting also presents a thin strip shape L1.

[0024] See also Figure 11-14Furthermore, the blade teeth 121 are in the shape of thin plates, which are long strips 123 arranged along the axial direction of the lower roller 12, and adjacent thin plates are arranged at intervals. In this way, the thin plates arranged axially cut the ice layer into thin strips along the width direction of the tape, and the length L2 of the strip is much smaller than the length L1 in the original scheme. The short-length single ice layer has a smaller bonding surface with the tape, and the bonding strength is also reduced, making it easier to separate from the working surface of the tape and fall off from the working surface of the tape.

[0025] Furthermore, the blade teeth 121 are in the shape of elongated columns 124, which are arranged radially along the lower roller 12, and adjacent blade teeth 121 are arranged at intervals. In this manner, after the irregularly arranged columns 124 come into contact with the ice layer on the tape, the ice layer is broken into irregular small pieces, and the contact area of ​​the irregular small pieces with the tape is reduced, and the ice layer is already fallen off.

[0026] Furthermore, a plug 125 is disposed at the end of the slender column 124 , and the diameter or width of the plug 125 is greater than the diameter of the column 124 .

[0027] Further, the plug 125 is movably connected to the end of the column 124. The column 124 made of metal has high hardness and directly contacts the tape, which is easy to cause mechanical scratches or damage to the tape. If the column 124 is bent or broken, it needs to be replaced. The lower end of the column 124 is connected to the roller body by welding to have a stable connection structure. If it is frequently replaced, the damaged column 124 needs to be cut off, and then the new column 124 is welded and fixed on the surface of the lower roller 12. Since multiple main columns 124 are arranged on the surface of the lower roller 12, multiple welding will reduce the surface strength of the lower roller 12 and the connection strength. Therefore, a replaceable plug 125 is provided. The plug 125 can be screwed or welded or clamped on the upper end of the column 124. The plug 125 with a larger diameter is not easy to scratch the tape, and multiple frictions will cause the plug 125 to wear. When replacing, only the plug 125 needs to be replaced, and the column 124 does not need to be replaced, and the connection between the column 124 and the lower roller 12 will not be damaged.

[0028] Furthermore, the upper roller 11 is a flat roller. The lower roller 12 is in contact with the working surface of the belt, and the working surface receives coal, which contains a large amount of water, etc., and is easily frozen on the working surface to form an ice layer. The ice layer on the working surface needs to be removed, and the back of the belt does not directly contact the coal, and there is almost no ice formation, so there is no need to set the same structure as the lower roller 12. Therefore, in this solution, the upper roller 11 is set as an ordinary flat roller, which only provides downward pressure. The upper roller 11 presses the belt tightly, so that the belt is in close contact with the lower roller 12, and then the blade teeth 121 on the lower roller 12 break the ice layer.

[0029] Furthermore, in a preferred embodiment, there are multiple upper rollers 11 and lower rollers 12, and the upper rollers 11 and lower rollers 12 are shoulder-stitched, and adjacent lower rollers 12 are respectively provided with blade teeth 121, wherein the blade teeth 121 of one lower roller 12 are long strip plates 123 arranged along the axial direction of the lower roller 12, and the blade teeth 121 of another adjacent lower roller 12 are circular ring structures 122 arranged along the radial direction of the lower roller 12 and surrounding the surface of the lower roller 12. In this solution, by simultaneously providing the axial blade teeth 121 and the radial blade teeth 121, the ice layer on the belt is cut and broken to form radial and axial small blocks, which are easy to fall off from the working surface of the belt.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of this patent.
