Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an automatic lubrication device for a crusher. Background Technology
[0002] The automatic lubrication device for crushers is a device specifically designed for the automated lubrication of crusher equipment. It completes the grease supply operation to each lubrication point of the crusher in a single process.
[0003] The basic structure of the automatic lubrication device for the crusher includes an oil storage device, an oil pump, a controller, and pipelines. The working principle is that the controller sends a command to start the oil pump at a preset time interval or the duration of equipment operation. The oil pump draws out the lubricating oil from the oil storage device at a specific flow rate, pressurizes it, and sends it to the corresponding parts to complete a full lubrication, ensuring the stable operation of the crusher.
[0004] Traditional automatic lubrication devices for crushers mostly use hydrocarbon organic compounds as lubricating oil, which are flammable. Inside the device, the high-speed operation of the oil pump, the rapid flow of lubricating oil in the pipeline, and the frequent opening and closing of the distributor all cause strong friction between the lubricating oil and the inner wall of the pipeline and mechanical parts. The automatic lubrication devices are mostly made of metal and plastic. Metal parts are prone to generating static electricity due to friction, while plastic materials are usually poor conductors of electricity and cannot effectively conduct static electricity. As the static charge continues to accumulate, when it reaches a certain level, an electrostatic discharge phenomenon will occur. The electric spark generated by this discharge can easily cause combustion or even explosion accidents in an environment filled with flammable lubricating oil vapor. Therefore, an automatic lubrication device for crushers is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 and Figure 2An embodiment of this utility model provides an automatic lubrication device for a pulverizer, comprising a base 1 and a pulverizer body 5. An oil storage tank 2 is fixedly connected to the top of the base 1. An oil pump 3 is installed at the end of the oil storage tank 2 away from the base 1. An oil delivery pipe 4 is fixedly connected to the output end of the oil pump 3. An oil injection pipe 6 is fixedly connected to the top of the pulverizer body 5. An oil filling pipe 8 is installed on the side of the oil storage tank 2 away from the pulverizer body 5. A quick-release filter assembly 13 is provided inside the oil filling pipe 8. A controller 7 is installed inside the oil storage tank 2. A collector 9 is fixedly connected inside the oil storage tank 2. A grounding wire 10 is fixedly connected to the side of the collector 9 away from the oil storage tank 2. The end of the oil delivery pipe 4 away from the oil pump 3 is located in the middle of the oil injection pipe 6. The oil pump 3 is electrically connected to the controller 7. A connecting post 11 is fixedly connected between the base 1 and the oil storage tank 2. An electrostatic spring 12 is sleeved on the outside of the connecting post 11. The oil storage tank 2 is made of galvanized steel. The grounding wire 10 and the electrostatic spring 12 are electrically connected through the oil storage tank 2.
[0032] Specifically, the controller 7 issues a start command according to a preset time interval or the operating time of the lubrication device, thus starting the oil pump 3. After starting, the oil pump 3 draws lubricating oil from the oil storage tank 2 using its own power and steadily delivers the lubricating oil to the oil injection pipe 6 at the top of the crusher body 5 through the oil delivery pipe 4. This completes the lubrication operation of the lubrication points of the crusher body 5, ensuring that the crusher body 5 can operate continuously and efficiently under good lubrication conditions, extending the overall service life of the equipment. During the operation of the lubrication device, static electricity is inevitably generated due to frequent friction between internal metal parts. At this time, the collector 9 can effectively collect some of the static electricity. The static electricity generated by friction is collected by the collector 9 and quickly and stably conducted to the ground through the grounding wire 10 connected to it, thus preventing the static electricity from accumulating inside the device. At the same time, another part of the static electricity is conducted to the static spring 12 sleeved on its outside through the connecting post 11. The static spring 12 is electrically connected to the grounding wire 10 and can also conduct the conducted static electricity to the ground. Through the coordinated operation of the collector 9, the grounding wire 10, the connecting post 11 and the static spring 12, the risk of safety accidents such as fire or explosion caused by static electricity accumulation is reduced, and the safety of the automatic lubrication device in flammable and explosive environments is improved.
[0033] Reference Figure 1 and Figure 3 The quick-release filter assembly 13 includes a filter plate 16, which is installed inside the filler pipe 8. A bolt 14 is installed between the filler pipe 8 and the filter plate 16. A bolt hole 17 is provided on the side of the filter plate 16 near the bolt 14. A slot 18 is provided on the top of the filler pipe 8. The filter plate 16 is slidably connected to the middle of the slot 18. The bolt 14 is threadedly connected to the middle of the bolt hole 17. A bolt hole 15 is provided in the middle of the filler pipe 8. The filler pipe 8 and the filter plate 16 are connected by the bolt 14.
[0034] Specifically, the oil can be conveniently added to the oil tank 2 via the oil filling pipe 8. During the filling process, the filter plate 16 inside the quick-release filter assembly 13 can filter the injected lubricating oil, effectively intercepting impurity particles in the oil and ensuring that the lubricating oil entering the oil tank 2 has good cleanliness, thereby ensuring the stability and reliability of subsequent lubrication operations. After the filter plate 16 has been used for a period of time, it needs to be replaced to maintain its filtering efficiency. At this time, by unscrewing the bolt 14 from the bolt hole 15 and bolt hole 17 in the middle of the oil filling pipe 8, the filter plate 16 can be smoothly removed from the oil filling pipe 8 by using the sliding connection structure between the slot 18 opened at the top of the oil filling pipe 8 and the filter plate 16, completing the replacement process. This method simplifies the replacement operation of the filter plate 16, reduces the time and labor costs required for maintenance, and improves the maintenance efficiency of the automatic lubrication device.
[0035] Working principle: The controller 7 issues a command to start the oil pump 3 according to the preset time interval or the running time of the equipment. After the oil pump 3 starts, it draws lubricating oil from the oil storage tank 2 and delivers it to the oil injection pipe 6 of the crusher body 5 through the oil delivery pipe 4 to complete the lubrication of the crusher body 5. During the operation of the device, the static electricity generated by the friction of the metal parts is collected by the collector 9. The collector 9 conducts the static electricity to the ground through the grounding wire 10. The other part of the static electricity is conducted to the static spring 12 through the connecting post 11. The static spring 12 is electrically connected to the grounding wire 10, and the static electricity is also conducted to the ground, thereby effectively preventing the accumulation of static electricity.
[0036] When adding oil to the oil reservoir 2, the operation can be carried out through the oil filling pipe 8. The filter plate 16 in the quick-release filter assembly 13 effectively filters the added lubricating oil to ensure the cleanliness of the lubricating oil. If the filter plate 16 needs to be replaced, it can be removed from the slot 18 of the oil filling pipe 8 by the cooperation of the bolt 14 with the bolt hole 15 and the bolt hole 2 17.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
