[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5 , a small oil mist lubrication and recovery integrated machine in this embodiment includes a box body 1 and a box door 2 installed on the front. The inner bottom wall of the box body 1 is fixed with a fuel tank 4. The top of the fuel tank 4 is fixed with a partition plate fixed to the inner top of the box body 1, and the bottom is fixed with a liquid outlet pipe two 28. The box body 1 is divided into a front chamber and a rear chamber by the partition plate. An oil mist recovery mechanism and a power mechanism connected to the oil mist recovery mechanism are installed in the rear chamber. The motive mechanism is also connected to the fuel tank 4. The top of the fuel tank 4 is provided with an oil mist output mechanism in the front chamber, and an explosion-proof electrical box is installed. The front of the fuel tank 4 is fixed with an oil injection pipe 10, and the oil injection pipe 10 is inclined upward.

[0022] In the above structure, by opening the box door, the oil mist output mechanism or the explosion-proof electrical box can be adjusted. At the same time, under the operation of the power mechanism, the oil mist recovery mechanism can operate to absorb the oil mist, and then the oil mist is introduced into the fuel tank for storage. At the same time, the oil mist can also be introduced inward through the oil injection pipe, and at the same time, in cooperation with the operation of the power mechanism, it can drive the oil mist output mechanism to operate, and the oil mist collected in the fuel tank can be exported for reuse. Therefore, the oil mist generation and recovery can be compacted on one device, reducing the floor area of the device and facilitating use and maintenance.

[0023] Such as Figure 3 and 4, The power mechanism includes a vacuum equipment chamber 14 formed at the rear chamber in the box body 1. A vacuum generator 15 is installed inside the vacuum equipment chamber 14. A negative pressure pipe 16 extending into the oil mist recovery mechanism and a compressed air inlet pipe 19 extending to the top of the box body 1 are installed on the vacuum generator 15. A valve is installed on the compressed air inlet pipe 19. One end of the compressed air inlet pipe 19 is connected to the oil mist output mechanism. An air discharge pipe 21 extending to the top of the box body 1 is fixed on the vacuum equipment chamber 14. Compressed air enters the vacuum generator through the compressed air inlet pipe, and can generate negative pressure in the oil mist recovery mechanism through the negative pressure pipe, so that external residual mist can be recovered into the fuel tank for collection. By closing the pipeline with the valve, compressed air enters the interior of the oil mist output mechanism to form negative pressure, and the oil liquid in the fuel tank is exported to complete the output operation.

[0024] Among them, taking Figure 4 as the indicated direction, the oil mist recovery mechanism includes an oil-gas separation chamber 11, a second confluence chamber 12 and a first confluence chamber 17 formed in the box body 1. The second confluence chamber 12 is located below the vacuum equipment chamber 14, and the second confluence chamber 12 is connected to the oil-gas separation chamber 11. Two filter elements 13 both connected to the first confluence chamber 17 are installed inside the oil-gas separation chamber 11. Two filter element orifice plates 22 corresponding to the filter elements 13 one by one are installed on the top of the box body 1. A residual mist recovery pipe 18 extending into the second confluence chamber 12 is fixed on the top of the box body 1. The residual mist recovery pipe 18 adopts a design of axially cutting part of the pipeline, which is beneficial to the uniformity of oil mist dispersion. The negative pressure pipe 16 extends into the first confluence chamber 17, and the pipe orifice of the negative pressure pipe 16 faces upward. Two liquid discharge pipes 27 and a second liquid level gauge 26 respectively connected to the second confluence chamber 12 and the first confluence chamber 17 are fixed on the front of the box body 1. When the vacuum generator operates, negative pressure is formed in the first confluence chamber through the negative pressure pipe. The oil mist is introduced through the residual mist recovery pipe. After introduction, the oil mist can be separated into oil and gas through the filter element. The air directly passes through the vacuum equipment chamber and is discharged to the atmosphere through the air discharge pipe. The oil liquid will be concentrated in the second confluence chamber. During long-term use, some will also fall into the first confluence chamber. Therefore, the internal accumulation situation can be observed through the second liquid level gauge. When the accumulation reaches a certain amount, it can be directly discharged through the liquid discharge pipe 27, or a pipeline can be connected to the liquid discharge pipe 27 to communicate with the fuel tank to complete the collection of the oil liquid.

[0025] In addition, taking Figure 3 as the indicated direction, the oil mist output mechanism includes an atomizing head 8 fixed on the top of the fuel tank 4 and connected to the compressed air inlet pipe 19. An oil mist output pipe 20 connected to the atomizing head 8 and extending to the top of the box body 1 is also fixed on the fuel tank 4. Through the cooperation of the vacuum generator and the compressed air inlet pipe, negative pressure is generated in the atomizing head, so that the oil liquid in the fuel tank can be pumped out and sprayed, and then exported through the oil mist output pipe for use, thus realizing the oil mist emission operation.

[0026] Still as Figure 4, an oil storage bin one 5 and an oil storage bin two 6 are formed inside the fuel tank 4. The area of the oil storage bin one 5 is larger than that of the oil storage bin two 6. The number of atomizing heads 8 and oil injection pipes 10 is two each, and they are respectively connected to the oil storage bin one 5 and the oil storage bin two 6. A plug is arranged at the pipe orifice of the oil injection pipe 10. The oil mist output pipe 20 is a tee pipe, and two of its branches are respectively connected to the two atomizing heads 8. A valve 23 for controlling the flow rate of the two branches is also installed on the outside of the oil mist output pipe 20. Anti-wave plates 9 are fixed inside both the oil storage bin one 5 and the oil storage bin two 6. A liquid level gauge one 25 corresponding to the anti-wave plate 9 is fixed on the front of the fuel tank 4. The oil storage bin two is an auxiliary oil bin. Usually, the oil in the oil storage bin one is used first. When the liquid level is observed to drop by the corresponding liquid level gauge one, the oil path is changed through the valve of the oil mist output pipe, so that the oil mist output pipe extracts the oil in the oil storage bin two. During this idle time, oil can be introduced through the corresponding oil injection pipe, or the oil in the confluence bin two and the confluence bin one can be exported and then imported, so that the replenishment of oil can be completed without shutting down the machine. At the same time, the anti-wave plate divides the internal space of the fuel tank to prevent the large-scale flow of oil. When the machine vibrates or moves, the fluctuation of the oil is blocked by the anti-wave plate, thereby reducing the fluctuation amplitude of the oil surface, so as to better observe the liquid level situation.

[0027] Among them, two heaters 7 are installed on the fuel tank 4, which are respectively located in the oil storage bin one 5 and the oil storage bin two 6. Oil usually becomes more viscous at lower temperatures, which will affect its fluidity and distribution in the system. By heating the oil with the heater, its viscosity can be reduced, making it easier to form fine oil mist particles, thereby improving the lubrication efficiency.

[0028] The working principle of the above embodiment is as follows:

[0029] Compressed air enters the vacuum generator through the compressed air inlet pipe. The vacuum generator creates negative pressure in the confluence bin one through the negative pressure pipe. Then the residual mist recovery pipe recovers the oil mist and enters the confluence bin two and the oil-gas separation bin. The residual mist is filtered by the filter element to separate the oil and air. The air is directly discharged to the atmosphere through the vacuum equipment bin and the air discharge pipe. The oil drops into the confluence bin one and the confluence bin two respectively before and after the filter element, and then the oil is exported through the liquid outlet pipe one and imported into the fuel tank for storage through the oil injection pipe, while completing the operation of oil mist recovery.

[0030] Meanwhile, by adjusting the valve on the compressed air inlet pipe, under the action of the vacuum generator, it cooperates with the atomizing head to make it in a negative pressure state, so that the oil in the fuel tank can be sucked out and atomized, and then led out through the oil mist output pipe. When the oil in the oil storage bin is almost used up, the valve on the oil mist output pipe can be adjusted to communicate with the second oil storage bin, so as to suck out the oil in the second oil storage bin for use, and at the same time replenish the oil in the first oil storage bin. Therefore, the replenishment can be completed without shutting down the machine, and continuous processing can also be carried out.

[0031] The entire working process is completed, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
