Description

Technical Field

[0001] The utility model relates to the technical field of grinding roller repair, in particular to a grinding roller oil grinding repair device. Background Art

[0002] Roller press is a high-pressure equipment, with a fixed roller and a movable roller, the two rollers rotate in opposite directions, the hydraulic system presses the movable roller to the fixed roller through 4 sets of hydraulic cylinders, the extrusion force F formed between the two rollers will squeeze the material between them into a dense flat cake, the mechanical strength of this cake is very low, it will break when twisted by hand, the cake contains a large amount of fine powder, of which the finished fine particles less than 90mm account for about 20-30%, the internal structure of the coarse particles has been destroyed, many microcracks are generated, and the wear resistance is very high, that is, in the extruded cake, the material particles less than 2mm account for about 60-70%, and there are many microcracks. This is because the material passing through the two rollers is subjected to a roller pressure of up to 120MPa in the pressure zone. During operation, the hydraulic device will continuously provide a huge pressure, and the roller press will also experience large vibration when the material is unstable. If the buffering capacity is poor, long-term operation will cause damage to the frame and roller bearings, resulting in damage to the equipment and even safety accidents.

[0003] Existing patent application announcement number CN210172763U The utility model discloses a roller oil wear repair device, a roller oil wear repair device, including a shell and a repair device, the inner wall of the shell is fixedly connected with a fixing hole on both sides, and the outer side of the fixing hole is fixedly connected with a heater, and the outer surface of the shell is provided with a movable groove on both sides. In the utility model, when the damaged roller needs to be repaired, it is only necessary to fix the two sides of the roller inside the fixing hole and rotate it, and the heating device connected to the outer side thereof increases the temperature of the roller, so as to facilitate the electric welding gun to repair the cracks on the surface of the roller, and by rotating the rotating shaft and lifting the lifting plate, the observation plate is moved to the position directly above the roller, and then the roller below is observed by the camera to detect the degree of wear and position of its surface, and then the telescopic column above the repair device moves and lifts in the slide slot to drive the electric welding gun to reach the specified repair position to repair the roller, thereby achieving the effect of repairing the worn roller.

[0004] In the existing technology, since the roller surface of the roller press is in direct contact with the material, the high-pressure extrusion stress is extremely large, and a fatigue layer of a certain thickness will be produced on the roller surface. Therefore, wear and tear will inevitably occur on the roller surface of the roller. After a period of operation, the roller with a worn surface must be replaced with a new roller. Since the new roller is expensive, the production cost is greatly increased. The existing technology requires the staff to move the grinding roller to the repair equipment when repairing the roller surface, which not only increases the labor intensity of the staff, but also has certain risks. The existing technology is not convenient for repairing grinding rollers of different models, which makes the equipment have certain limitations. Utility Model Content
