Description

Technical Field

[0002] Thickener is a solid-liquid separation equipment based on gravity sedimentation, which is widely used in many fields such as mineral processing, hydrometallurgy, sewage treatment, paste filling and tailings dry stacking. The thickener can use the rake running at a low speed to discharge the thickened bottom flow through the motor or pump through the bottom flow outlet. It is mainly used for clarifying and concentrating coal slime water or ore slurry in mines to achieve the purpose of dehydration. It has the characteristics of large processing capacity and high bottom flow concentration.

[0003] The slewing bearing is a large bearing that can withstand comprehensive loads. It is often used as a force transmission component between the drive reducer and the center shaft in the thickener. The slewing bearing needs to be lubricated before use. At present, manual grease filling is generally used. When the filling amount is insufficient or uneven, it will lead to insufficient lubrication and a long filling time, which increases the labor intensity of workers. At the same time, after long-term operation, the grease gradually ages and does not meet the lubrication needs. When the old grease needs to be replaced, there is a common problem that the grease in the bearing cannot be discharged smoothly. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0021] Depend on Figure 1 Combination Figure 2-3 As shown, a slewing bearing lubrication structure for a steel thickener includes a driving element 1, a first supporting plate 2, a second supporting plate 3 and a driving short circuit 4. The first supporting plate 2, the second supporting plate 3 and the driving short circuit 4 cooperate with each other to form a lubricating oil tank 5. A slewing bearing 6 is arranged in the lubricating oil tank 5. A lubricating mechanism 7 is arranged on the first supporting plate 2. The lubricating mechanism 7 includes a lubricating power source 71 and an oil filling pipe 72. The lubricating power source 71 is connected to the lubricating oil tank 5 through the oil filling pipe 72 and injects lubricating oil into the lubricating oil tank 5. The beneficial effect of the utility model is that the first supporting plate, the second supporting plate and the driving short circuit cooperate with each other to form a lubricating oil tank, which can store lubricating oil and supply oil through the lubricating mechanism, so that the slewing bearing can be reliably lubricated, and the parts can be lubricated in an oil bath, avoiding manual grease filling. The utility model also has the advantages of simple structure, convenient assembly, reliable operation and long service life. Specifically, the driving element is a reducer, and the first support plate, the second support plate and the driving short circuit cooperate with each other to form a closed cavity structure. Lubricating oil is added to the cavity through the lubrication power source (oil pump) of the lubrication mechanism, so that when the reducer rotates, the driving pinion (driving gear) and the slewing bearing and the inside of the slewing bearing can be lubricated by oil bath. The beneficial effects of the utility model are: the structure is simple and practical, and it solves the problem of manual grease filling. When the filling amount is insufficient or uneven, it will lead to insufficient lubrication, and the filling time is long, which increases the labor intensity of the workers. At the same time, it solves the problem that the grease gradually ages after long-term operation and does not meet the lubrication needs. When the old grease needs to be replaced, the grease in the bearing cannot be discharged smoothly.

[0022] The slewing bearing 6 includes an inner ring 61 and an outer ring 62 sleeved outside the inner ring 61. The driving element 1 includes a driving gear 11. The driving gear 11 is meshed with the outer ring 62 of the slewing bearing 6. The outer ring 62 is linked to the driving short circuit 4. Such a structure enables the driving gear to reliably drive the outer ring to rotate. Usually, the inner ring is fixed on the second support plate, and the outer ring rotates relative to the inner ring. The outer ring, the inner ring, and the driving gear are all soaked in lubricating oil.

[0023] There are multiple driving elements 1, and the driving gears 11 of the multiple driving elements are all meshed with the outer ring 62 of the slewing bearing 6 and rotate synchronously. Specifically, the second support plate 3 is provided with a groove portion 31, the groove portion 31 is connected to the lubricating oil tank 5, and the driving gear 11 is inserted into the groove portion 31. The provision of the groove portion can facilitate the installation of multiple driving elements, especially a position is reserved for accommodating the driving gear, so that the product volume is small.

[0024] The second support plate 3 is provided with a baffle 32, and the baffle 32 is arranged on the inner side of the inner ring 61 of the slewing bearing 6. Such a structure enables the closed cavity formed by the second support plate and the first support plate to contain replaceable lubricating oil, and the structure is simple.

[0025] The first support plate 2 is provided with a through hole 21, and the inner wall of the through hole 21 is provided with a mounting plate 22 for fixing the driving element 1. Such a structure is convenient for installing and fixing the driving element, has a simple structure, and a small gap between the housing of the driving element and the first support plate, and the product is relatively stable.

[0026] The driving short circuit 4 is provided with a plurality of partitions 41, and a reinforcement groove 42 is formed between adjacent partitions 41. Such a structure increases the strength of the driving short circuit and reduces the material, making the product structure simple, while reducing the friction between the driving short circuit and the baffle.

[0027] The oil drain pipe 73 on the second support plate 3 is inserted into the second support plate 3 and connected to the lubricating oil tank 5. The oil drain pipe 73 is provided with a control valve for opening and closing the oil drain pipe 73. Generally speaking, the control valve can be a ball valve, or a gate valve. Specifically, the oil filling pipe 72 is provided on the side of the first support plate 2 away from the oil drain pipe 73. Generally speaking, the oil drain pipe is provided below the second support plate. The waste oil can be conveniently discharged through the oil drain pipe below the lubricating oil tank, avoiding the situation where the old grease is not completely discharged and contaminates the new grease.

[0028] The first support plate 2 is provided with a hollow groove 23, and the horizontal height of the driving short circuit 4 is lower than the horizontal height of the second support plate 3. Such a structure reduces the material and enhances the strength of the first support plate.
