Description

Technical field:

[0001] The utility model relates to the field of lubrication systems, in particular to an air pump type atomizing oil spraying device. Background technology:

[0002] The atomizing oil spray device is a commonly used component in the equipment lubrication system. Its main function is to spray the lubricating oil into the corresponding working mechanism in atomized form to reduce friction during operation of the mechanism and extend the service life of the equipment.

[0003] Traditional atomizing oil sprayers, which operate on the principle of negative pressure spraying, require the oil tank to be filled with a mixture of compressed air and grease at a certain pressure before normal oil spraying can be achieved. For example, a typical tank capacity is 2L. Therefore, 2L of compressed air is lost each time the machine is shut down and started. For example, in the oil sprayer for a knitting machine disclosed in Chinese Patent Publication No. CN 208857447 ​​U, during operation, an air compressor 25 introduces air into the oil tank 1 via a pressurized air pipe 26. The pressurized lubricating oil in the oil tank 1 enters the second hose 51 and then, through the adapter 34, into the third hose 33. It is then accelerated and sprayed out of the nozzle 35 of the nozzle head 32, thereby supplying the lubricating oil. However, this method requires the introduction of air into the oil tank 1 to increase its pressure, which not only results in significant gas consumption but also requires high airtightness for the oil tank 1, making it difficult to manufacture and process, increasing production costs, and posing the risk of explosion due to excessive air pressure during atomization.

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] See Figures 1 to 9 The figure shows an air pump type atomizing oil spray device, comprising: an oil nozzle 11, an atomizing chamber 7 connected to the oil nozzle 11, an atomizer 2 installed in the atomizing chamber 7 and connected to a first air inlet pipe 31, and an oil suction chamber 12 for supplying oil to the atomizer 2, the atomizer 2 and the oil suction chamber 12 are connected by an oil suction pipe 32, the oil suction chamber 12 has an oil supply pump 4 for supplying oil thereto through an oil supply pipe 33, the oil supply pump 4 includes a piston seat 41, a piston 42 slidingly arranged in the piston seat 41, an air intake joint 43 arranged at one end of the piston seat 41 and used to push the piston 42 to move, a pump cylinder 44 arranged at the other end of the piston seat 41 and connected to the oil supply pipe 33, and a return spring 45 for pushing the piston 42 back, wherein an oil inlet port 441 is provided at one end of the pump cylinder 44, and the oil inlet port 441 is immersed in oil. The oil supply pump 4 is used to directly pump oil into the oil suction chamber 12, replacing the traditional method of pressurizing the oil into the oil tank 10. This not only greatly reduces the consumption of compressed air and saves costs, but also significantly reduces the sealing requirements of the oil tank 10, facilitates the processing and production of the oil tank 10, and further reduces production costs. Secondly, the oil supply pump 4 adopts a needle-type cylinder structure. By connecting the air intake connector 43 to the air supply source, no additional power device is required, which greatly saves costs. The use of the return spring 45 as the return power of the piston 42 not only simplifies the structure of the oil supply pump 4 and facilitates the rapid return of the piston 42, but also makes it easy to process, produce and assemble, significantly reducing production costs.

[0028] The oil inlet 441 is located at the interface between the pump cylinder 44 and the piston seat 41. The piston 32 continuously enters the oil inlet 441 during its reciprocating motion. The piston 42 is positioned between a return spring 45 and an air inlet connector 43. Furthermore, the return spring 45 is positioned between the pump cylinder 44 and the piston 42. Gas introduced into the piston seat 41 from the air inlet connector 43 pushes the piston 42 into the pump cylinder 44, and the return spring 45 pushes the piston 42 out of the pump cylinder 44. The oil inlet 441 of the pump cylinder 44 is immersed in lubricating oil. Using the principle of communicating vessels, the lubricating oil 441 will automatically flow into the pump cylinder 44. When the piston 42 is pushed into the pump cylinder 44 by air pressure, the lubricating oil is squeezed and pushed into the oil supply pipe 33. When the piston 42 loses the air pressure thrust, the piston 42 exits the pump cylinder 44 under the push of the return spring 45, and the lubricating oil will enter the pump cylinder 44 again from the oil inlet 441. During the rapid reciprocating motion of the piston 42, the lubricating oil will be quickly pushed into the oil supply pipe 33 little by little, thereby achieving oil pumping.

[0029] The intake connector 43 and pump cylinder 44 are threadedly mounted on either end of the piston seat 41. The intake connector 43 is connected to the source via an air supply pipe 46. The air supply pipe 46 is equipped with a solenoid valve 47 and a pressure regulating valve 48, which are controlled by a controller. A check valve 49 is located within the pump cylinder 44, located between the oil inlet 411 and the oil supply pipe 33. The controller controls the opening and closing of the solenoid valve 47, which in turn controls the push and retraction of the needle cylinder. The piston 42 within the needle cylinder reciprocates within the pump cylinder 44, pressurizing oil through the oil supply pipe 33 into the oil suction chamber 12. Simultaneously, compressed air within the first intake pipe 31 flows into the atomizer 2, creating a vacuum in the oil suction pipe 32. The oil suction pipe 32 is connected to the interior of the oil suction chamber 12. Liquid flows through the oil suction pipe 32 to the atomizer 2, where it mixes with the air in the first intake pipe 31 and is sprayed out as a mist.

[0030] See Figure 4 In the first embodiment, the atomizer 2 includes a manifold 21 for connecting the first air inlet pipe 31 and the oil suction pipe 32, and an atomizer block 22 disposed on the manifold 21. The atomizer block 22 is located directly in front of the air outlet 211 of the manifold 21. A high-speed airflow is injected into the atomizer 2 through the first air inlet pipe 31, creating a negative pressure within the manifold 21. Oil is drawn from the oil suction chamber 12 into the atomizer 2. The oil is then struck by the atomizer block 22 with the high-speed airflow, forming an oil mist. The oil mist then flows out of the nozzle 11 with the airflow and is sprayed onto the working mechanism for lubrication, reducing friction between parts and increasing the service life of the equipment.

[0031] The atomizing block 22 is formed with a first atomizing groove 221 and a second atomizing groove 222 facing different directions, and a first connecting hole 223 is formed between the first atomizing groove 221 and the second atomizing groove 222. The first connecting hole 223 is directly opposite to the air outlet 211, and the diameter of the first connecting hole 223 is smaller than that of the air outlet 211. By forming the atomizing block 22 into two double-layer atomizing grooves, the first atomizing groove 221 and the second atomizing groove 222 are connected by the first connecting hole 223, and the first connecting hole 223 is directly opposite to the air outlet 211. The air outlet 211 is located at the first connecting hole 223, which is smaller than the air outlet 211. This allows the high-speed airflow ejected from the air outlet 211 to carry a portion of the oil and hit the first atomizing groove 211 to generate oil mist. The remaining portion of the oil follows the airflow through the first connecting hole 223 and hits the second atomizing groove 222 to generate oil mist. This increases the atomization volume and allows all the oil to be atomized. This eliminates the need for a reserved oil return channel in the atomizer 2 and allows for the generation of even finer oil mist particles. This is then sprayed with the airflow and adheres to the lubrication points, allowing it to enter smaller gaps for lubrication, resulting in a better lubrication effect. Conventional oil spray head atomizers, on the other hand, cannot completely convert oil into oil mist and require a channel on the atomizer for the oil to return to the oil tank.

[0032] The manifold 21 is provided with a first channel 212 linearly connected to the air outlet 211 and connected to the first air intake pipe 31, and a second channel 213 perpendicular to the first channel 212 and connected to the oil suction pipe 32. The first air intake pipe 31 is connected to the first channel 212 via a first connecting nozzle 311, and the oil suction pipe 32 is connected to the second channel 213 via a second connecting nozzle 321. The second channel 213 is perpendicular to the first channel 212, so that airflow passing through the first channel 212 generates negative pressure in the second channel 213, thereby drawing oil from the oil suction chamber 12 through the oil suction pipe 32 and into the first channel 212, where it flows with the airflow.

[0033] See Figure 9 In the second embodiment, the atomizer 2 includes a communicating vessel 21 for connecting the first air inlet pipe 31 and the oil suction pipe 32, a sealing plate 23 provided at one end of the communicating vessel 21 and mounted on the bottom of the atomizing chamber 7, a third atomizing groove 24 provided on the communicating vessel 21, and a plurality of communicating holes 25 provided on the sealing plate 23 for supplying oil mist into the atomizing chamber 7, wherein the communicating vessel 21 is provided with a first channel 212 that is linearly connected to the air outlet 211 and connected to the first air inlet pipe 31, and a second channel 213 that is perpendicular to the first channel 212 and connected to the oil suction pipe 32, the third atomizing groove 24 intercepts the first channel 212 between the second channel 213 and the sealing plate 23, and is located outside the atomizing chamber 7. The first air inlet pipe 31 is installed and connected to the first channel 212 through a first connecting nozzle 311, the oil suction pipe 32 is installed and connected to the second channel 213 through a second connecting nozzle 321, and the communicating holes 25 are circumferentially located on the periphery of the communicating vessel 21. A high-speed airflow is sprayed into the atomizer 2 through the first air inlet pipe 31, so that a negative pressure is generated in the communicating vessel 21, and the oil is drawn from the oil suction chamber 12 into the atomizer 2. After the oil is mixed with the high-speed airflow, a small part of the oil-gas mixture directly flows into the oil mist in the atomizing chamber 7 through the first channel 212 along with the high-speed air flow. Most of the oil-gas mixture will hit the groove wall to form oil mist after passing through the third atomizing groove 24, and diffuse outward from the third atomizing groove 24. After the oil mist is dispersed and diffused in the oil tank 10, the oil mist in the oil tank 10 will flow into the atomizing chamber 7 from the communicating hole 25 due to the negative pressure generated after the high-speed airflow enters the atomizing chamber 7, and flow out from the nozzle 11 along with the high-speed airflow to be sprayed on the working mechanism for lubrication, reducing the friction between parts and increasing the service life of the equipment.

[0034] The oil injection nozzle 11, the oil suction chamber 12, and the atomizing chamber 7 are all mounted on the oil cup head 1. The oil suction pipe 32 is connected to the bottom of the oil suction chamber 12 via a third connecting nozzle 322, and is connected to the upper end of the oil suction chamber 12. An oil sight cap 121 is mounted on the upper end of the oil suction chamber 12. By opening the oil sight cap 121, the oil level in the oil suction chamber 12 can be observed to determine whether the oil injection nozzle is functioning properly. It can also be used to check whether the oil supply of the oil pump 4 is stable and whether it meets the current lubrication needs.

[0035] The oil cup head 1 is also provided with an oil filling port 13 located next to the oil sight cap 121. The oil cup head 1 is mounted on the fuel tank 10. A plurality of oil spray nozzles 11 are mounted on the oil cup head 1, and the oil spray nozzles 11 are evenly distributed around the oil cup head 1 in a circumferential pattern. The oil cup head 1 is also provided with two hanging ears 14.

[0036] An air filter 6 is provided on one side of the oil cup head 1 to provide high-speed airflow to the first air intake pipe 31. A third channel is formed on one side of the oil cup head 1 to connect to the air filter 6. The first air intake pipe 31 is connected to the third channel via a fourth connecting nozzle 312. The air filter 6 is connected to the air intake connector 43 via a pipe. The air filter 6 filters the high-speed airflow generated by the air compressor, ensuring that it is free of impurities and maintaining the quality of the high-speed airflow.

[0037] To sum up, the working principle of the utility model is as follows: first, a sufficient amount of oil is added to the oil tank to submerge the oil inlet 441 of the oil supply pump 4 in the oil; further, the oil supply pump 4 pumps the oil into the oil suction chamber 12 through the oil supply pipe 33, so that a certain amount of oil is stored in the oil suction chamber 12; further, a high-speed airflow is sprayed into the atomizer 2 by the first air inlet pipe 31, and under the action of the high-speed airflow, the atomizer 2 generates a negative pressure to draw the oil from the oil suction chamber 12 through the oil suction pipe 32. After mixing with the airflow, the oil flows into the atomization chamber 7 with the airflow, thereby generating a tiny oil mist; further, after a large amount of oil mist is formed in the atomization chamber 7, it flows out through the oil nozzle 11 with the airflow, and is finally sprayed and attached to the lubrication point.

[0038] In the present invention, there is no need to inflate the oil tank 10 to pressurize the oil into the oil suction chamber 12. Only the 0.02L volume of the atomizing chamber 7 requires gas. Under the same shutdown and start-up conditions, the present invention can save 90% of compressed gas waste compared to existing products. The number of shutdowns and starts per day for different materials varies greatly, with more frequent shutdowns exceeding 100 times per day. Based on this calculation, assuming a company has 100 knitting machines * 100 shutdowns * 2L * 0.9 = 18,000m2 of compressed gas can be saved per day. 3 Compressed gas.

[0039] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
