Description

Technical Field

[0001] This utility model belongs to the technical field of atomization equipment, specifically relating to a lubricating oil atomization device. Background Technology

[0002] In reducers, engines, or high-precision machine tools, oil mist lubrication is generally used as the primary method for lubricating components. Besides supplying lubricating oil to the lubrication points, the oil mist also provides heat exchange for the components. In production workshops, the compressed air used to deliver lubricating oil is usually generated by an air compressor, and the temperature of the compressed air produced by the air compressor is relatively low. Before reaching the atomizing nozzle, the lubricating oil mixes with the compressed air in the atomization chamber. The low temperature of the compressed air is conducted to the lubricating oil, lowering its temperature and increasing its viscosity. This results in poor atomization when passing through the atomizing nozzle, leading to larger particles sprayed from the nozzle. Consequently, the oil mist sprayed onto the components is not uniform, resulting in poor lubrication.

[0003] Existing technology discloses a lubricating oil supply device (publication number: CN 212805194 U). This device uses a first heating device installed along the path of a second pipeline to neutralize the low temperature of the compressed air generated by the air compressor, thereby maintaining the temperature of the lubricating oil in the atomizing device within a suitable range. However, the newly added first heating device requires additional energy consumption and does not effectively utilize the heat generated during lubrication and heat exchange of the components themselves, resulting in high energy consumption and poor energy-saving effect. Therefore, it is necessary to improve the lubricating oil atomizing device. Utility Model Content

[0008] Furthermore, a honeycomb mesh and a funnel are installed at intervals inside the liquid-gas generator.

[0009] Furthermore, the inner wall of the liquid-gas generator is provided with at least two gas outlets in the vapor flow space, and the gas outlets are connected to the delivery pipeline and the atomizing nozzle.

[0010] Furthermore, the delivery pipeline includes at least two output pipelines and an output main pipe connected to the output pipelines, and each output pipeline is equipped with a control valve.

[0011] Different output pipes can output vapor mist of different particle sizes, and each output pipe can be used individually or in combination, improving the flexibility of vapor mist spraying.

[0012] Furthermore, the delivery pipeline is connected to one end of the return gas pipeline, and the other end of the return gas pipeline is connected to the gas supply pipeline.

[0013] Furthermore, a driver is installed on the top of the liquid-gas generator, and the output end of the driver extends into the liquid-gas generator and is equipped with turbine blades. By driving the turbine blades to rotate, the vapor in the vapor flow space can be pressurized and output.

[0014] Furthermore, the bottom wall of the liquid-gas generator is designed as a slope that is higher in the middle and lower at the outer edge, which helps to settle impurities.

[0015] Furthermore, the bottom wall of the liquid-gas generator is provided with a waste discharge port.

[0016] Furthermore, the bottom wall of the liquid-gas generator is embedded with a magnet.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0028] like Figures 1 to 5 As shown, in one embodiment, a lubricating oil atomizing device includes a liquid-gas generator 101, a delivery pipeline, and an atomizing nozzle 117. The liquid-gas generator 101 has, from bottom to top, a lubricating oil containing space D, a vaporization space C, and a vapor flow space B. The wall of the liquid-gas generator 101 is provided with an air supply port 122, an oil supply port 121, and an oil return port 125. The air supply port 122 connects to the bottom of the vaporization space C and the air supply pipeline. The air supply pipeline includes a compressed air pipeline (not shown) and a T-connector 105. The first port of the tee pipe 105 is installed at the air supply port 122. The second port of the tee pipe 105 serves as the air supply interface 104, connecting to the compressed air pipeline for supplying compressed air. The third port of the tee pipe 105 is a spare and can be sealed with a plug. The oil supply port 121 connects to the middle of the vaporization space C and the oil supply pipeline 102. The oil supply pipeline 102 includes a lubricating oil tank, an oil pump, and an oil supply pipe. The oil pump is located inside the lubricating oil tank and connects to the oil supply port 121 and the middle of the vaporization space C via the oil supply pipe, thereby delivering lubricating oil to the vaporization space C. The vapor flow space B is connected to the atomizing nozzle 117 via a delivery pipeline, and the return oil port 125 connects to the lubricating oil receiving space D and the return oil pipeline 107.

[0029] For example, the delivery pipeline includes a first output pipe 108, a second output pipe 110, and a third output pipe 112 connected in parallel, and an output main pipe 115. The first output pipe 108, the second output pipe 110, and the third output pipe 112 are all connected to the output main pipe 115. Control valves are installed on the first output pipe 108, the second output pipe 110, and the third output pipe 112, namely: a first control valve 109, a second control valve 111, and a third control valve 113, to realize the control of the on / off state, flow rate, and flow velocity of the first output pipe 108, the second output pipe 110, and the third output pipe 112.

[0030] Alternatively, a control valve can be installed at the first output pipe 108, the junction of the first output pipe 108 and the second output pipe 110, and the front end of the main output pipe 115 to control each pipe.

[0031] For example, the bottom wall of the liquid-gas generator 101 is provided with a waste discharge port 123, and a waste discharge pipe 103 is installed at the waste discharge port 123 for discharging waste oil in the liquid-gas generator 101.

[0032] In this embodiment, compressed air from the factory workshop is supplied through an air supply pipeline. The compressed air enters the vaporization space C via the air supply interface 1074, the three-way pipe 105, and the air supply port 122. The oil supply pipeline 102 is connected to a lubricating oil tank or lubricating oil container. The atomizing nozzle 117 is located in the area where the target workpiece is located, and atomizes and sprays the lubricating oil onto the target workpiece. In the vaporization space C, the compressed air supplied by the air supply pipeline vaporizes the lubricating oil supplied by the oil supply pipeline 102 and flows to the vapor flow space B, and is then transported to the atomizing nozzle 117 via the delivery pipeline. The end of the return oil pipeline 107 is located in the area where the target workpiece is located, and it recovers the excess lubricating oil generated and can carry away some heat, returning it to the lubricating oil holding space. This heat can be utilized by evaporating the lubricating oil, which can improve the energy efficiency of this device and reduce energy waste.

[0033] For example, an oil supply bypass pipe can be connected between the oil supply pipe 102 and the lubricating oil containing space D, so that the lubricating oil in the lubricating oil containing space D can be utilized.

[0034] For example, the end of the oil return pipe 107 can be configured as follows: an oil receiving tank is provided in the area where the target workpiece is located, and a recovery oil pump 118 is provided in the oil receiving tank. The recovery oil pump 118 is connected to the end of the oil return pipe 107; in this way, the lubricating oil can be recovered and reused.

[0035] like Figure 1 , Figure 4As shown, in this embodiment, three gas outlets 124 are provided on the inner wall of the liquid-gas generator 101 in the vapor flow space B. The gas outlets 124 are connected to the delivery pipeline and the atomizing nozzle 117.

[0036] Among them, the three gas outlets 124 are connected to different heights of the vapor flow space B. The air pressure will change at different heights, and the floating height of the vapor in the vapor flow space B will also be different, resulting in different particle sizes of the vapor output from the gas outlets.

[0037] For example, multiple atomizing nozzles 117 are provided. In fact, multiple atomizing nozzles 117 can be mounted in a linear array through an integrated housing to form an atomizing nozzle assembly 116.

[0038] In fact, the gas outlet 124 in this embodiment can also be selected as one or two as needed; when set to one, the structure of this device is the simplest, but it can still realize the utilization of the heat generated by lubricating the workpiece, which is energy-saving and environmentally friendly.

[0039] Correspondingly, the delivery pipeline includes three lines: the first output pipeline 108, the second output pipeline 110, and the third output pipeline 112, as well as the main output pipeline connected to the output pipelines. Each of the output pipelines is equipped with a control valve.

[0040] In fact, the delivery pipeline includes one or two output pipelines, as well as a main output pipe connected to the output pipelines, and each of the output pipelines is equipped with a control valve.

[0041] For example, the delivery pipeline is connected to one end of the return gas pipeline 114, and the other end of the return gas pipeline 114 is connected to the gas supply pipeline.

[0042] Specifically, the other end of the return gas pipeline 114 is connected to one end of the return gas switch valve 106, and the other end of the return gas switch valve 106 is connected to the third port of the three-way pipe 105.

[0043] The proportion of gas delivered to the air supply port 122 through the three-way pipe 105 can be flexibly controlled by the control valve installed on the compressed air pipeline and the return gas switch valve 106 installed thereon, which is highly flexible and practical.

[0044] For example, the return gas pipe 114 can be connected in both directions.

[0045] like Figure 1 , Figure 5As shown, in this embodiment, a honeycomb mesh 126 and a funnel 130 are installed at intervals inside the liquid-gas generator 101. The honeycomb mesh 126 has honeycomb-shaped through holes 127. An oil leakage cavity 128 is installed at the bottom of the honeycomb mesh 126 and is suspended above the funnel 130. A lubricating oil containing space D is formed between the bottom of the funnel 130 and the bottom wall of the liquid-gas generator 101. A vaporization space C is formed between the oil leakage cavity 128 and the inner wall of the funnel and the inner wall of the liquid-gas generator 101. A vapor flow space B is formed between the top of the honeycomb mesh 126 and the inner wall of the liquid-gas generator 101. The oil leakage cavity 128 is connected to the oil supply port 121 through an oil supply branch pipe 129. The funnel 130 is provided with a jacket 131. A gas distribution port 132 is opened on the inner wall surface of the funnel 130. The jacket 131 is connected to the gas supply port 122.

[0046] When the lubricating oil is vaporized, the compressed air supplied to the jacket 131 through the air supply port 122 is evenly dispersed through the gas distribution port 132. The compressed air is supplied to the oil supply port 121 through the oil supply branch pipe 129 and then to the oil leakage chamber 128. The lubricating oil leaking from the bottom of the oil leakage chamber 128 is vaporized. The vapor mist generated by vaporization enters the vapor mist flow space B through the through hole 127, and then is transported to the atomizing nozzle through the conveying pipeline to spray out, thereby realizing the atomization spraying of the lubricating oil.

[0047] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, a driver 120 is installed on the top of the liquid-gas generating tank 101. The output end of the driver 120 extends into the liquid-gas generating tank 101 and is equipped with turbine blades.

[0048] For example, a cover plate 119 is screwed onto the top of the liquid-gas generator 101, and a servo motor is selected as the driver 120, which is mounted on the cover plate 119. By driving the turbine blades to rotate, the vapor in the vapor flow space B can be pressurized and output. In fact, compressed air has a certain pressure, and this device can also output vapor even when the servo motor is not involved in the delivery, which has high flexibility and practicality.

[0049] like Figure 5 As shown, in this embodiment, the bottom wall of the liquid-gas generator 101 is set as an inclined surface with a high middle and a low outer edge; a magnet is embedded in the bottom wall of the liquid-gas generator 101.

[0050] For example, the inclined surface is set so that the recovered lubricating oil enters the liquid-gas generator 101 in a submerged manner without affecting the pressure of the vapor flow space B and the vaporization space C; the waste discharge port 123 is also set at the bottom of the liquid-gas generator 101; the magnet has a certain magnetic attraction force, which can adsorb impurities in the recovered lubricating oil; the impurities are then discharged through the waste discharge port 123.

[0051] For example, common materials for manufacturing liquid-gas generators include stainless steel, carbon steel, fiberglass, aluminum alloy, and plastics. A liquid-gas generator 101 made of stainless steel or fiberglass can be selected to ensure excellent pressure resistance, corrosion resistance, and lightweight properties. In addition, fiberglass energy storage tanks have excellent heat insulation performance, making them suitable for lubricating oils that require temperature control; they can withstand high temperature and high pressure environments while having good heat insulation performance to reduce heat loss.

[0052] This embodiment provides a lubricating oil atomizing device. Compressed air supplied through an air supply pipeline and lubricating oil supplied through an oil supply pipeline are atomized in a vaporization space and flow into a vapor flow space. The atomized oil then flows through a delivery pipeline and atomizing nozzles to lubricate the target workpiece. A return oil pipeline allows for the recovery and reuse of the lubricating oil. This device can recover and utilize the heat generated during lubrication and heat exchange, resulting in high energy utilization. The pressure and flow rate of each pipeline are controlled by control valves, leading to a high degree of automation, strong practicality, and broad market potential.

[0053] The above provides a detailed description of the lubricating oil atomizing device provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
