Description

Technical Field

[0001] The utility model relates to the technical field of cone crushers, in particular to an air-oil integrated dustproof and lubrication system for cone crushers. Background Art

[0002] Cone crusher is a material crushing machine, widely used in metal and non-metallic mines, cement plants, sand and stone metallurgy and other industries, suitable for crushing iron ore, granite, limestone, quartzite, sandstone, river pebbles, etc. When the cone crusher is working, the motor drives the eccentric sleeve to rotate through the V-belt, transmission shaft and transmission gear, and the moving cone performs a pendulum motion under the action of the eccentric sleeve, so that the moving cone and the fixed cone are sometimes close and sometimes deviated, and the material is constantly squeezed and impacted in the crushing chamber and crushed, and the crushed material is discharged from the bottom.

[0003] During the crushing process, a large amount of dust will be generated in the crushing chamber of the equipment. The dust entering the moving cone will damage the motion chamber, contaminate the lubricating oil, and affect the normal operation of the equipment. At present, there are two main types of dust seals for cone crushers: labyrinth seals and positive pressure dust seals. The labyrinth seal uses U-shaped sealing rings and T-shaped sealing rings for dust sealing. This sealing method can only prevent a small amount of external dust from entering, and as the crushing part rotates, the sealing ring and the components produce friction, causing wear. The positive pressure dust seal is to process the air path on the frame, send compressed air into the motion chamber, and form a positive pressure system in the chamber, which can effectively prevent a large amount of dust from entering. However, since the frame is a casting with a large thickness, it is complicated to open holes in the frame, and the processing is difficult. In addition, the downward-flowing lubricating oil encounters the upward air flow, causing oil splashing, thereby affecting the lubrication effect. Utility Model Content

[0020] like Figure 1-2 As shown, the embodiment of the present application discloses an integrated gas-oil dust prevention and lubrication system for a cone crusher, including a main shaft 1 arranged in the cone crusher, wherein a lubricating oil main channel 2, a lubricating oil branch channel 3, an air pipe 4 and an air branch pipe 6 are arranged in the main shaft 1, and the air pipe 4 is arranged in the lubricating oil main channel 2, so that the existing holes on the main shaft 1 can be directly used for arrangement, which reduces the workload of hole opening, saves processing costs, and facilitates later maintenance. The lubricating oil enters the lubricating parts of the cone crusher through the lubricating oil main channel 2 and the lubricating oil branch channel 3 for lubrication, and the external compressed air enters through the air pipe 4 and the air branch pipe 6 and fills the moving sub-cavity of the cone crusher, so that a positive pressure state is formed inside the equipment, preventing external dust from entering the interior and contaminating the lubricating oil. Figure 1 As shown, the thick arrows indicate the flow direction of the lubricating oil, and the thin arrows indicate the flow direction of the compressed gas.

[0021] In the specific configuration, a lubricating oil main channel 2 is provided in the main shaft 1 along its length direction, and a plurality of lubricating oil branch channels 3 are radially provided on the main shaft 1 and are connected to the lubricating oil main channel 2. The lubricating oil branch channels 3 extend from the main shaft 1 to the lubricating parts of the cone crusher. An air-oil integrated block 7 is provided at the bottom end of the main shaft 1, and the air-oil integrated block 7 is connected to the main shaft 1 by bolts. An annular groove 12 is provided on the end face of the air-oil integrated block 7 adjacent to the main shaft 1, and a sealing ring is placed in the annular groove 12. The sealing ring can be an O-ring or other forms, so that the connecting surface between the air-oil integrated block 7 and the main shaft 1 can be sealed when the air-oil integrated block 7 is connected to the main shaft 1. An integrated channel 8 is provided downward from the main shaft 1 in the air-oil integrated block 7, and the aperture of the integrated channel 8 is consistent with the diameter of the lubricating oil main channel 2. When the air-oil integrated block 7 is connected to the main shaft 1, the integrated channel 8 is aligned with the lubricating oil main channel 2 so that the integrated channel 8 is connected to the lubricating oil main channel 2. A lubricating oil inlet 9 connected to the integrated channel 8 is provided on the side wall of the gas-oil integrated block 7, so that the lubricating oil can enter the integrated channel 8 through the lubricating oil inlet 9, and then enter the lubricating parts of the cone crusher through the lubricating oil main channel 2 and the lubricating oil branch channel 3.

[0022] An air main pipe 4 is arranged in the lubricating oil main channel 2. The lower end of the air main pipe 4 extends into the integrated channel 8 and passes through the bottom of the integrated channel 8. A connector 10 is arranged at the end of the air main pipe 4 passing through the bottom of the integrated channel 8. The connector 10 is connected to an air inlet pipe 11.

During the setting, the diameter of the through hole in the main shaft 1 is consistent with the outer diameter of the gas branch pipe 6. A sealing ferrule joint is provided on the gas branch pipe 6 near the main shaft 1. The sealing ferrule joint and the gas branch pipe 6 are sealed and connected with the main shaft 1 to prevent lubricating oil leakage. The multi-channel joint 5 and the gas main pipe 4 and the gas branch pipe 6 are all connected by threaded sealing. Other methods such as flanges can also be used for sealing connection, but the sealing of the connection must be guaranteed.

[0023] The operating principle of the integrated air-oil dustproof and lubrication system of a cone crusher in the present embodiment is as follows: the lubricating oil enters the integrated channel 8 from the lubricating oil inlet 9, and then enters the lubricating parts of the cone crusher through the lubricating oil main channel 2 and the lubricating oil branch channel 3 for lubrication; the external compressed gas enters from the air inlet pipe 11, and reaches the moving sub-cavity in the moving cone of the cone crusher through the connector 10, the air main pipe 4, the multi-channel joint 5, and the air branch pipe 6. Since the compressed gas enters the moving sub-cavity of the cone crusher from the upper end of the main shaft 1, a positive pressure state is formed inside the equipment, which can not only better prevent dust from entering and contaminating the lubricating oil, but also avoid splashing of the lubricating oil.
