Description
Technical Field
The invention relates to the technical field of belt cleaning, in particular to a belt bonding layer stripping machine.
Background
The belt conveyer is widely applied to material conveying of metallurgical mines. When the belt runs, a small amount of materials are often brought out in the return stroke and are scattered along the way, the scattered materials are accumulated to cause environmental pollution on the one hand, and if the belt is not cleaned timely, installation accidents can be caused due to long-time accumulation. Therefore, the belt blanking and cleaning operation of factory and mining enterprises is large in workload, and occupies a lot of post human resources.
A common method for solving the problem of belt adhesion is to arrange a belt cleaning device, typically a roller brush or a belt scraper, at a position close to the discharge roller on the belt return stroke. Roller brush and scraper often respond well at new belt initial stage, and along with the lapse of time, the effect is more and more poor, even loses the effect. The reason is that after the belt is unloaded, a layer of adhesive formed by mixing ultrafine powder and water is left on the surface of the belt, the layer of adhesive is in a slurry state at the initial stage, the thickness of the layer of adhesive is very thin and is usually between 1 mm and 3mm, and the existing roller brush and the existing scraping device cannot remove the layer of adhesive. As time goes by, the water in the adhesive layer evaporates, the adhesive layer becomes hard and thick, the bonding strength between the adhesive layer and the belt is enhanced, and the removal becomes more and more difficult, and fig. 1 is a schematic diagram of the formation process of the bonding layer. Because the adhesive layer is composed of the powder of the raw material body, the adhesive layer has strong affinity with the raw material, once the adhesive layer is completely covered, the adhesive of the belt is rapidly deteriorated, the difficulty of removing the adhesive is rapidly improved, and even the adhesive cannot be removed. The phenomenon of material sticking is serious after the belt runs for a period of time, and the cleaning effect of the belt cleaner is poor or even cannot be eliminated.

As shown in fig. 4 and 5, the bonding layer on the surface of the return belt 3 is subjected to high-pressure impact generated by the pumping of the stripping whip 2 at the pumping point, so as to form collapse, after the stripping whip 2 leaves, the bonding layer at the pumping point is rapidly decompressed, and the pumping point is exploded and falls off under the action of internal high pressure. Through constantly taking out the hit, the consolidation layer appears droing in a large number, and when return belt 3 accepted the material once more, its surface is because no longer be adhered with the consolidation layer, and the affinity greatly reduced of belt surface and material, viscidity greatly reduced has reduced the degree of adhesion of belt, has effectively improved clear material effect and efficiency.
In the running process of the belt conveyor, a belt for bearing materials is discharged through the discharging roller 4 and then enters a return stroke. The belt bonding layer stripping machine in the embodiment is arranged below the return belt 3 at the discharging roller 4, and the return belt 3 is cleaned at the first time after the discharging of the return belt 3 is completed, so that the formation, growth and hardening of the bonding layer are further avoided. In other embodiments, the belt bonding layer stripping machine may be disposed at other positions according to circumstances, which is not described herein.
In this embodiment, the length of the stripping whip 2 along the axial direction of the stripping roller 1 is not less than the width of the return belt 3, and when the stripping whip 2 is arranged, the symmetry axis of the stripping roller 1 coincides with the symmetry axis of the belt width direction, so that the stripping whip 2 can cover the return belt 3 along the width direction of the return belt 3, and the bonding layer on the return belt 3 is completely removed.
In this embodiment, as shown in fig. 2, the peeling whip 2 is a sheet-shaped member extending outward in the radial direction of the peeling roller 1, and the sheet-shaped peeling whip 2 continuously mounted on the peeling roller 1 can completely peel in the width direction of the return belt 3, thereby greatly improving the peeling effect.
In this embodiment, the length from the fixed end of the peeling whip 2 and the peeling roller 1 to the contact end of the peeling whip 2 and the return belt 3 is greater than the distance from the surface of the peeling roller 1 to the surface of the return belt 3, so as to ensure that the peeling whip 2 can contact the return belt 3, and thus the stripping and the stripping of the bonding layer are performed.
In this embodiment, the peeling whip 2 is made of a material with good toughness, and the peeling whip 2 with good toughness can achieve a good tapping effect. When the contact end of the stripper whip is contacted with the return belt 3, the contact end of the stripper whip 2 and the surface of the return belt 3 form a joint area with the maximum joint width L, and L is more than or equal to 10mm and less than or equal to 20 mm. As shown in fig. 4 and 5, the bonding region is the coverage of the suction point, and the bonding layer in the coverage can be peeled off by the suction of the peeling whip 2.
In this embodiment, the peeling whip 2 is provided with four groups, and each group of peeling whip 2 is uniformly arranged around the axis of the peeling roller 1. In order to ensure that each bonding layer of the return belt 3 along the length direction can be stripped by suction impact, the rotating speed of the stripping roller 1 and the running speed of the return belt 3 must satisfy a certain relation.

The speed measuring press roller 5 is tightly attached to the inner side surface of the return belt 3, so that the return belt 3 is positioned between the speed measuring press roller 5 and the stripping roller 1, and the speed measuring press roller 5 can control the position of the return belt 3 in such a way that the return belt 3 cannot be changed in position under the pumping action of the stripping whip 2; the belt speed detector 6 detects the running speed of the return belt 3 by detecting the rotating speed of the speed-detecting pressure roller 5, the peeling roller rotating speed detector 7 detects the rotating speed of the peeling roller 1, and the driver 8 drives the peeling roller 1 to rotate; the control system determines whether ω is S/(4L) based on the running speed of the return belt 3 measured by the belt speed detector 6 and the rotation speed of the peeling roller 1 measured by the peeling roller rotation speed detector 7, and controls the driving speed of the driving machine 8 based on the determination result.
For example, when the rotation speed of the peeling roller 1 is slow and ω ═ S/(4L) cannot be satisfied, the control system controls the driving machine 8 to increase the driving speed so that the rotation speed of the peeling roller 1 is increased until ω ═ S/(4L) is satisfied. In this embodiment, the output shaft of the driving machine 8 is in transmission connection with the peeling roller 1 through a belt, and in other embodiments, other transmission connection modes can be adopted, which are not described herein.
