DETAILED DESCRIPTION

[0017] Refer to the following Figures 1 to 7 The lubrication cooling system and lubricating oil cooling method for a cone crusher according to an embodiment of the present invention will be described.

[0018] Figure 1 Schematic diagram of the lubrication and cooling system for a cone crusher according to an embodiment of the present invention. Figure 1 As shown, and refer to Figures 2 to 7 An embodiment of the present invention provides a lubrication and cooling system for a cone crusher, which includes a temperature sensor, an oil pump 10 and an oil tank 20 for containing lubricating oil.

[0019] A plurality of first oil chambers 21 and a plurality of second oil chambers 22 are provided in the oil tank 20. The plurality of first oil chambers 21 are arranged in sequence along a straight line, and the plurality of second oil chambers 22 are arranged on one side of the plurality of first oil chambers 21. Each adjacent two first oil chambers 21 are connected through a first opening. A first opening and closing device for adjusting the size of the first opening is provided at each first opening. Each adjacent two second oil chambers 22 are connected through a second opening. A second opening and closing device for adjusting the size of the second opening is provided at each second opening. Each first oil chamber 21 is connected to a second oil chamber 22 on one side thereof through a third opening. A third opening and closing device for adjusting the size of the third opening is provided at each third opening. One of the first oil chambers 21 is an oil return chamber 24, and the second oil chamber 22 on one side of the first oil chamber 21 is an oil outlet chamber 25. The temperature sensor is used to detect the oil temperature of the lubricating oil entering the oil return chamber 24, so as to control the first opening and closing device, the second opening and closing device and the third opening and closing device according to the oil temperature. The oil return chamber 24 is used to receive the lubricating oil returned from the lubricating point 12 on the cone crusher, and the lubricating oil in the oil outlet chamber 25 is supplied to the lubricating point 12 on the cone crusher through the oil pump 10.

[0020] When the lubrication and cooling system for the cone crusher of the embodiment of the present invention is in operation, the oil pump 10 is in operation, and the lubricating oil in the oil outlet chamber 25 enters the lubrication point 12 on the cone crusher through the oil pump 10, and the lubricating oil at the lubrication point 12 returns to the oil tank 20 to be cooled. The oil temperature of the return oil obtained by the temperature sensor controls the openings of the first opening, the second opening, and the third opening, so that the lubricating oil in the return oil chamber 24 has different cooling paths. When the oil temperature is relatively high, the openings of the first opening and the second opening can be the largest. At this time, the lubricating oil in the return oil chamber 24 will mainly pass through the multiple first oil chambers 21 and the multiple second oil chambers 22 in sequence, and then reach the oil outlet chamber 25. The travel route and cooling route of the lubricating oil are both relatively long, which is conducive to the cooling of high-temperature lubricating oil. When the oil temperature is relatively low, the opening of the third opening can be maximum, and the lubricating oil in the return oil chamber 24 can mainly enter the second oil chamber 22 through the first oil chamber 21. The moving path and the cooling path are relatively short, meeting the cooling requirements. In this way, part of the lubricating oil does not participate in the lubrication work, or participates in the lubrication for a relatively short time, that is, part of the lubricating oil is naturally used for lubrication, so that the remaining part of the lubricating oil basically does not participate in the lubrication, and there is less temperature change, which is beneficial to protect the overall quality of the lubricating oil and increase the service life of the lubricating oil.

[0021] In the embodiment of the present invention, the return oil temperature of the lubricating oil may be different for different crushing objects, and the return oil temperature of the lubricating oil can be automatically detected, thereby automatically switching the openings of the first opening, the second opening and the third opening, and automatically determining the amount of lubricating oil involved in lubrication according to the movement of the liquid itself, which is conducive to the rational use of the lubricating oil, the protection of the lubricating oil, and the increase of the service life of the lubricating oil.

[0022] In some embodiments of the present invention, Figure 3 As shown, a connecting oil chamber 23 is further provided in the oil tank 20. The connecting oil chamber 23 is provided at one end of the first oil chamber 21 and the second oil chamber 22, and the connecting oil chamber 23 is connected to the first oil chamber 21 through the first opening, and is connected to the second oil chamber 22 through the second opening. The connecting oil chamber 23 is provided to facilitate the rapid connection between the first oil chamber 21 and the second oil chamber 22, and to prevent a large amount of lubricating oil from accumulating in the first oil chamber 21 and lacking oil in the second oil chamber 22 due to the third opening.

[0023] In some embodiments of the present invention, the first oil chamber 21, the second oil chamber 22 and the connecting oil chamber 23 are arranged in two groups and are symmetrically arranged. The two return oil chambers 24 are arranged adjacent to each other and are connected, and the two oil outlet chambers 25 are arranged adjacent to each other and are connected. By arranging two groups, the cooling efficiency of the lubricating oil can be further improved.

[0024] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the oil tank 20 includes a box body 26, a box cover 27 and a partition 28. The partition 28 is arranged in the box body 26 to divide the space in the box body 26 into a plurality of first oil chambers 21 and a plurality of second oil chambers 22. The box cover 27 closes the upper opening of the box body 26. The partition 28 has a plurality of first openings, a plurality of second openings and a plurality of third openings. A lifting space is arranged inside the partition 28 at positions corresponding to the first openings, the second openings and the third openings. The first opening and closing device, the second opening and closing device and the third opening and closing device all include a baffle 31 and a lifting device 30. The baffle 31 is arranged in the corresponding lifting space on the baffle 28 so as to be movable up and down. The lifting device 30 is configured to drive the baffle 31 to rise or fall. The opening of each opening is adjusted by driving the baffle 31 by the lifting device 30.

[0025] In some embodiments of the present invention, Figure 2 and Figure 7 As shown, the lifting device 30 includes an electromagnet 32 ​​and a magnet 33 disposed at the upper end of the baffle 31. The electromagnet 32 ​​is disposed on the upper side of the box 26 and is configured to change the magnetic pole in a controlled manner to drive the magnet 33 to move upward or downward. The lifting space can protect the magnet 33 and prevent the magnet 33 from being covered and wrapped by the lubricating oil. The baffle 31 is driven up and down by the magnet 33 by changing the magnetic pole of the electromagnet 32, so that there is no need to set a connecting hole on the box 26 for the lifting device 30 to give way, thereby ensuring the sealing performance of the box 26 and preventing the leakage of lubricating oil as much as possible. The control using the electromagnet 32 ​​is simple, easy to use, and has a compact structure.

[0026] In some embodiments of the present invention, Figure 3As shown, a first lubricating oil cooling device 40 is provided in each first oil chamber 21, and a second lubricating oil cooling device 50 is provided in each second oil chamber 22. In particular, the power of the first lubricating oil cooling device 40 can be adjusted to control the power of the first lubricating oil cooling device 40 according to the oil temperature. For example, the first lubricating oil cooling device 40 corresponding to the first oil chamber 21 that is farther away from the oil return chamber 24 has a greater power, that is, more cooling capacity is provided. For example, when the oil temperature of the returned lubricating oil is high, the cooling capacity provided by the first lubricating oil cooling device 40 becomes larger and larger. For the oil return chamber 24, the oil temperature is high, the cooling capacity is small, and the cooling amplitude of the lubricating oil is the first amplitude. For the first oil chamber 21 that is farthest from the oil return chamber 24, the oil temperature is low, the cooling capacity is large, and the cooling amplitude of the lubricating oil is the second amplitude. Such a setting can make the first amplitude and the second amplitude equal, and can make full use of energy. That is, the oil temperature is getting lower and lower, and the cooling device is getting colder and colder, so that the temperature difference in each first oil chamber 21 changes basically the same, and is basically reduced according to a fixed temperature difference.

[0027] If the oil temperature of the return oil chamber 24 is high, the cooling capacity is the same, and the cooling amplitude of the lubricating oil is the third amplitude, and the oil temperature of the first oil chamber 21 farthest from the return oil chamber 24 is low, the cooling capacity is the same, and the cooling amplitude of the lubricating oil is the fourth amplitude, it is obvious that the third amplitude is greater than the fourth amplitude, so that the cooling capacity cannot be reasonably utilized, and the third amplitude causes the lubricating oil to be rapidly cooled, and the amplitude of each change in oil temperature is not consistent, which is not conducive to protecting the quality of the lubricating oil. The present invention can make the heat released by each first oil chamber 21 as consistent as possible, that is, the cooling amplitude of the lubricating oil is basically consistent, the lubricating oil will not be rapidly cooled, and the heat of the lubricating oil can be fully used, so that the lubricating oil dissipates heat evenly during a long distance trip, which is conducive to protecting the lubricating oil and making full use of the structure of the oil tank 20 to prevent a large heat dissipation at one end and a small heat dissipation at the other end.

[0028] In some embodiments of the present invention, Figures 2 to 6As shown, the lubrication and cooling system for the cone crusher also includes a coolant tank 51 and a coolant pump 52. The first lubricating oil cooling device 40 includes a first cooling pipeline 41, a heat sink fin 42 and a semiconductor cooling fin 43. The first cooling pipeline 41 is arranged in the first oil cavity 21. Coolant is arranged in the first cooling pipeline 41. The inlet of each first cooling pipeline 41 is connected to the outlet of the coolant pump 52, and the outlet of each first cooling pipeline 41 is connected to the coolant tank 51. The heat sink fin 42 is arranged in the first oil cavity 21, and the heat sink fin 42 is connected to the bottom wall of the first oil cavity 21. The semiconductor cooling fin 43 is arranged on the lower side of the bottom wall of the first oil cavity 21, the cold end of the semiconductor cooling fin 43 is in contact with the bottom wall of the first oil cavity 21, and the hot end of the semiconductor cooling fin 43 is connected to the fin heat sink 44. By arranging the semiconductor cooling fin 43, the power of the first lubricating oil cooling device 40 can be adjusted. The heat dissipation of the semiconductor cooling fin 43 is easy to adjust, and it is also easier to provide heat when heating is needed in winter. The first cooling pipeline 41 is provided to ensure sufficient basic cooling capacity, and the semiconductor cooling plate 43 is provided to provide more efficient, quick and convenient cooling, thereby ensuring the cooling effect of the lubrication cooling system for the cone crusher.

[0029] Preferably, in some embodiments of the present invention, in each first oil chamber 21, the first cooling pipeline 41 is arranged on the upstream side of the heat dissipation fins 42. That is, during cooling, the lubricating oil first passes through the first cooling pipeline 41 and then passes through the heat dissipation fins 42, so as to prevent the basic cooling capacity of the first cooling pipeline 41 from being fully utilized when the lubricating oil first passes through the heat dissipation fins 42.

[0030] In some embodiments of the present invention, the second lubricating oil cooling device 50 includes a second cooling pipeline 55, and the second cooling pipeline 55 is arranged in the second oil chamber 22. Coolant is arranged in the second cooling pipeline 55. The inlet of each second cooling pipeline 55 is connected to the outlet of the coolant pump 52, and the outlet of each second cooling pipeline 55 is connected to the coolant tank 51. In the embodiment of the present invention, the first lubricating oil cooling device 40 is mainly used for cooling the lubricating oil, and the second lubricating oil cooling device 50 is mainly used for auxiliary cooling.

[0031] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the lubrication and cooling system for the cone crusher also includes a high-pressure pump 61, a first high-pressure oil chamber 62 and a second high-pressure oil chamber 63. The high-pressure pump 61 is configured to pump the lubricating oil 10 in the oil outlet chamber 25 into the first high-pressure oil chamber 62 and the second high-pressure oil chamber 63. The first high-pressure oil chamber 62 is arranged on the upper side of the plurality of first oil chambers 21. When the pressure oil in the first high-pressure oil chamber 62 reaches a certain value, the high-pressure oil is sprayed into the plurality of first oil chambers 21. When the pressure oil in the second high-pressure oil chamber 63 reaches a certain value, the high-pressure oil is sprayed into the plurality of second oil chambers 22. Specifically, the first high-pressure oil chamber 62 is connected to a plurality of first nozzles 64 and a first valve, and each first nozzle 64 is installed in a first oil chamber 21. The first valve is used to control the on-off between the first high-pressure oil chamber 62 and the first nozzle 64. The second high-pressure oil chamber 63 is connected to a plurality of second nozzles 65 and a second valve, and each second nozzle 65 is installed in a second oil chamber 22. The second valve is used to control the on-off between the second high-pressure oil chamber 63 and the second nozzle 65. The outlet of the high-pressure pump 61 is connected to the first high-pressure oil chamber 62 and the second high-pressure oil chamber 63 through the switching valve. The high-pressure pump 61 is used to pump lubricating oil into the first high-pressure oil chamber 62 and the second high-pressure oil chamber 63 through the switching valve. The lubricating oil is stirred in the first oil chamber 21 or the second oil chamber 22 by spraying the high-pressure oil, thereby improving the cooling efficiency of the lubricating oil.

[0032] In particular, the lubrication and cooling system for the cone crusher also includes a first pipeline 66 and a second pipeline 67. The inlet of the first pipeline 66 is connected to the first high-pressure oil chamber 62, and the outlet of the first pipeline 66 leads to the lubrication point 12. The inlet of the second pipeline 67 is connected to the second high-pressure oil chamber 63, and the outlet of the second pipeline 67 leads to the lubrication point 12. Normally closed valves are provided on the first pipeline 66 and the second pipeline 67, and the normally closed valves are opened when the cone crusher is powered off, so that the lubricating oil in the first high-pressure oil chamber 62 and the second high-pressure oil chamber 63 enter the lubrication point 12 to continue lubrication. When the cone crusher is powered off, it will continue to work due to inertia. At this time, the oil pump 10 cannot work due to power failure and cannot provide lubricating oil, which will cause the cone crusher to be damaged due to poor lubrication. In the embodiment of the present invention, because there are the first high-pressure oil chamber 62 and the second high-pressure oil chamber 63, lubricating oil can continue to be provided to prevent the cone crusher from being damaged due to power failure.

[0033] In the embodiment of the present invention, only when the first high-pressure oil chamber 62 is filled with lubricating oil can the second high-pressure oil chamber 63 release lubricating oil through the second nozzle 65. Only when the second high-pressure oil chamber 63 is filled with lubricating oil can the first high-pressure oil chamber 62 release lubricating oil through the first nozzle 64. To prevent the first high-pressure oil chamber 62 and the second high-pressure oil chamber 63 from being unable to continue to provide lubricating oil to the lubrication point 12 due to lack of lubricating oil in the event of a sudden power outage. Moreover, in the embodiment of the present invention, only when the oil temperature is higher than a preset value can the first high-pressure oil chamber 62 release lubricating oil through the first nozzle 64 and / or the second high-pressure oil chamber 63 release lubricating oil through the second nozzle 65 to improve the cooling effect.

[0034] The embodiment of the present invention further provides a cooling method for the lubrication cooling system of the cone crusher in any of the above embodiments, comprising: The oil temperature of the lubricating oil entering the oil return chamber 24 is obtained.

[0035] When the oil temperature is lower than the first temperature value, the third opening and closing device is controlled to make the third opening at the ninth opening, the first opening and closing device is controlled to make the first opening at the first opening, and the second opening and closing device is controlled to make the second opening at the fourth opening. The first opening has a first opening, a second opening, and a third opening that increase in sequence. The second opening has a fourth opening, a fifth opening, and a sixth opening that increase in sequence. The third opening has a seventh opening, an eighth opening, and a ninth opening that increase in sequence.

[0036] When the oil temperature is higher than or equal to the second temperature value, the first opening and closing device is controlled to make the first opening at the third opening, the second opening and closing device is controlled to make the second opening at the sixth opening, and the third opening and closing device is controlled to make the third opening at the seventh opening. The first temperature value is less than the second temperature value.

[0037] When the oil temperature is higher than or equal to the first temperature value and lower than the second temperature value, the first opening and closing device is controlled to make the first opening at the second opening degree, the second opening and closing device is controlled to make the second opening at the fifth opening degree, and the third opening and closing device is controlled to make the third opening at the eighth opening degree.

[0038] In the embodiment of the present invention, the return oil temperature of the lubricating oil may be different for different crushing objects, and the return oil temperature of the lubricating oil can be automatically detected, thereby automatically switching the openings of the first opening, the second opening and the third opening, and automatically determining the amount of lubricating oil involved in lubrication according to the movement of the liquid itself, which is conducive to the rational use of the lubricating oil, the protection of the lubricating oil, and the increase of the service life of the lubricating oil.

[0039] In some embodiments of the present invention, the cooling method of the lubrication cooling system for a cone crusher further comprises: When the oil temperature is lower than the first temperature value, a preset number of first lubricating oil cooling devices 40 and second lubricating oil cooling devices 50 are turned on. When the preset number of first lubricating oil cooling devices 40 are turned on, the first lubricating oil cooling devices 40 corresponding to the first oil chamber 21 farther from the oil return chamber 24 are not turned on, and the first lubricating oil cooling devices 40 closer to the oil return chamber 24 are turned on until the preset number of first lubricating oil cooling devices 40 are turned on. When the preset number of second lubricating oil cooling devices 50 are turned on, the first lubricating oil cooling devices 40 corresponding to the second oil chamber 22 farther from the oil outlet chamber 25 are not turned on, and the second lubricating oil cooling devices 50 closer to the oil return chamber 24 are turned on until the preset number of first lubricating oil cooling devices 40 are turned on.

[0040] When the oil temperature is equal to the third temperature value, all the first lubricating oil cooling devices 40 and the second lubricating oil cooling devices 50 are turned on. The third temperature value is less than the second temperature value and greater than the first temperature value.

[0041] When the oil temperature is greater than the fourth temperature value, the power of the first lubricating oil cooling device 40 is increased, and the power of the first lubricating oil cooling device 40 corresponding to the first oil cavity 21 farther from the oil return cavity 24 increases more. The fourth temperature value is greater than the second temperature value.

[0043] In some embodiments of the present invention, the cooling method of the lubrication cooling system for a cone crusher further comprises: When the oil temperature is greater than the fifth temperature value, the first high-pressure oil chamber 62 is controlled to release lubricating oil through the first nozzle 64; After the first high-pressure oil chamber 62 can release the lubricating oil through the first nozzle 64 for a preset number of times, the second high-pressure oil chamber 63 is controlled to release the lubricating oil through the second nozzle 65, and then the first high-pressure oil chamber 62 is returned to be controlled to release the lubricating oil through the first nozzle 64. The fifth temperature value is greater than the fourth temperature value.
