Description

Technical Field

[0001] The present invention relates to the technical field of vacuum pumps, and in particular to a self-lubricating vertical vacuum pump. Background Art

[0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical, or physical-chemical methods to evacuate a container to obtain a vacuum. A vacuum pump is a device that improves, generates, and maintains a vacuum in a closed space by various methods. According to the working principle of the vacuum pump, the vacuum pump can basically be divided into two types, namely, gas capture pumps and gas transfer pumps, which are widely used in industries such as metallurgy, chemical industry, food, and electronic coating.

[0003] When using a vertical vacuum pump, the drive shaft installed thereon is a key component. Through the cooperation of the motor, the rotating shaft can drive components such as the impeller inside the vertical vacuum pump to work in cooperation, enabling the vertical vacuum pump to operate normally. However, the part where the drive shaft contacts the pump body shell often undergoes friction, resulting in resistance when the drive shaft rotates, making the rotation less smooth and affecting the normal operation of the vertical vacuum pump. Moreover, it is usually necessary to manually lubricate the contact part between the rotating shaft and the pump body shell, which is rather troublesome. Summary of the Invention

The end of the collecting pipe away from the diverging pipe is arranged inside the annular chamber. A one-way valve is arranged on the outer side wall of the collecting pipe near one end of the annular chamber.

[0010] In the above-mentioned self-lubricating vertical vacuum pump, a movable ring is sleeved inside the annular chamber. A plurality of rotating blades are fixedly connected to the outer side wall of the movable ring. A ring groove is penetrated and opened on the inner side wall of the annular chamber.

One end of the connecting plate is fixedly connected to the outer side wall of the transmission shaft, and the other end is fixedly connected to the inner side wall of the movable ring. A plurality of spray pipes are fixedly connected to the outer side wall of the annular chamber.

[0011] In the above-mentioned self-lubricating vertical vacuum pump, the overheat lubrication mechanism includes a processing box and an arc-shaped heat conduction chamber. The processing box is arranged above the motor. The arc-shaped heat conduction chamber is fixedly connected to the outer wall of the motor. Support frames are fixedly connected to both side walls of the processing box near the bottom end, and the bottom ends of the two support frames are fixedly connected to the bottom plate.

[0012] In the above-mentioned self-lubricating vertical vacuum pump, a storage box is inserted into the bottom end inside the processing box. Both the storage box and the arc-shaped heat conduction chamber are filled with mercury. A square connecting short pipe is fixedly connected to the outer wall of the top of the arc-shaped heat conduction chamber. The arc-shaped heat conduction chamber is communicated with the storage box through the square connecting short pipe.

[0013] In the above-mentioned self-lubricating vertical vacuum pump, on both inner side walls of the treatment box near the middle position, there are fixed mounting plates. Inside the treatment box and at the upper surface position of the two sets of mounting plates, there is inserted a push plate. Between the upper surface of the push plate near the four corners and the inner top of the treatment box, there are connected second springs. Between the upper surface of the push plate and the inner top of the treatment box, there is a rubber oil storage bin. On the outer wall of the top of the treatment box, there is fixedly connected a connecting pipe and an oil injection pipe. One end of the connecting pipe is fixedly connected to the rubber oil storage bin, and the other end is arranged inside the annular bin. On the outer wall of the connecting pipe near one end of the annular bin, there is a check valve II. On the outer wall of the oil injection pipe, there is a check valve III.

[0014] In the above-mentioned self-lubricating vertical vacuum pump, on the outer wall of the top of the storage box, there is fixedly connected a square connecting long pipe. On both inner side walls of the square connecting long pipe near the bottom end position, there are fixedly connected bearing plates. Between the top outer wall of the bearing plate and the inner top of the square connecting long pipe, there is fixedly connected a limiting rod. Outside the limiting rod, there is sleeved a movable plate. On the top outer wall of the movable plate, there is fixedly connected a push rod. The upper end of the push rod is fixedly connected to the push plate. On the outer wall of the push rod near the upper end position, there is fixedly connected a support plate. And the end of the support plate far away from the push rod is fixedly connected to the bottom surface of the push plate.

[0015] Compared with the existing technology, the advantages of this self-lubricating vertical vacuum pump are as follows:

[0016] 1. During the operation of the vertical vacuum pump, the vibration generated causes the oil storage tank and the transverse pipe in the vibration lubrication mechanism to vibrate, and the pipe plug arranged inside vibrates. When it moves to the inside of the flow cavity, the lower end of the oil outlet pipe loses blockage. The lubricating oil inside the oil storage tank flows through the oil outlet pipe to the inside of the transverse pipe under the action of gravity, and then flows through the two shunt pipes and the collecting pipe to the inside of the annular bin, and is sprayed onto the bearing surface through the spray pipe to lubricate it. Through the above operations, it can be made that when the vertical vacuum pump operates and generates vibration, the bearing is continuously and automatically lubricated, making the transmission shaft rotate more smoothly and avoiding affecting the normal operation of the vertical vacuum pump.

[0017] 2. When heat is generated on the surface of the motor, part of the heat is absorbed and dissipated by each arc-shaped heat conduction bin in the overheat lubrication mechanism, and the absorbed heat causes the mercury inside the arc-shaped heat conduction bin to heat up, and gradually transfers the heat to the inside of the storage box, making the mercury inside the storage box heat up and expand, causing it to flow into the inside of the square connecting long pipe, making the movable plate move upward along the limiting rod, the push rod follows the movable plate to move upward, driving the push plate to move upward, squeezing the rubber oil storage bin, making the lubricating oil inside it flow out through the connecting pipe to the inside of the annular bin, and similarly, it is then sprayed onto the bearing through the spray pipe to lubricate the bearing. Through the above operations, it can be made that when the motor works for a long time and generates heat, the bearing is automatically lubricated, increasing the lubrication effect on the bearing.

[0018] 3. The connecting plate rotates following the transmission shaft, which can drive the movable ring to rotate. The rotating blades rotate following the movable ring to stir the lubricating oil entering the interior of the annular bin, enabling the lubricating oil to continuously rotate and flow within the annular bin. This can prevent the lubricating oil from depositing at the bottom of the annular bin under the action of gravity, causing uneven oil output and affecting the lubrication effect on the bearings.

[0019] In summary, by setting up the vibration lubrication mechanism, the present invention can continuously and automatically lubricate the bearings when using this vertical vacuum pump without manual lubrication, making the rotation of the transmission shaft smoother. And by setting up the overheat lubrication mechanism, when the motor heats up, it can automatically lubricate the bearings, increasing the lubricating oil amount for the bearings and making the lubrication effect on the bearings better, thus making the operation of this vertical vacuum pump smoother.

Detailed implementation mode

[0030] 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.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0032] Refer to Figures 1 - 9 , a self-lubricating vertical vacuum pump, including a bottom plate 1, a first pump body 2 is fixedly installed on the outer wall of the top of the bottom plate 1 near one side, a motor 5 is fixedly installed on the outer wall of the top of the bottom plate 1 near the other side, a plurality of heat sinks 49 are fixedly connected to the outer wall of the motor 5, a second pump body 3 is fixedly installed on the outer wall of the top of the first pump body 2, two interfaces 4 are fixedly installed on the outer wall of the second pump body 3, an output shaft 7 is installed on one side of the motor 5, a connecting ring 6 is fixedly connected to the outer wall of the output shaft 7, a transmission shaft 8 is rotatably connected to the outer wall of the first pump body 2, a transmission wheel 9 is fixedly connected to the outer wall of the transmission shaft 8, a bearing 47 is fixedly connected to the outer wall of the transmission shaft 8 away from the transmission wheel 9, a plurality of belts 10 are sleeved between the transmission wheel 9 and the outside of the connecting ring 6, a protective housing 11 is fixedly connected to the outer wall of the bottom plate 1, a vibration lubrication mechanism 42 for spraying oil to lubricate the bearing 47 is arranged on the outer wall of the first pump body 2, and an overheat lubrication mechanism 43 for triggering oil injection lubrication at high temperature is arranged on the outer wall of the top of the motor 5.

[0033] The motor 5 drives the connecting ring 6 to rotate through the output shaft 7, so that the belt 10 is cooperated to drive the transmission wheel 9 to rotate, and then drives the transmission shaft 8 to rotate. The other end of the transmission shaft rotates in the pump body 1 through the bearing 47, so that the vacuum pump can be started to work, and air and other media can enter the vertical vacuum pump through the interface 4.

[0034] The vibration lubrication mechanism 42 includes an oil storage tank 44 and an annular chamber 21. The oil storage tank 44 is fixedly connected to the outer side wall of the pump body 1. The annular chamber 21 is sleeved outside the transmission shaft 8. Three connecting plates 25 are fixedly connected to the side of the annular chamber 21 close to the pump body 1, and the ends of the three connecting plates 25 far from the annular chamber 21 are all fixedly connected to the outer side wall of the pump body 1.

[0035] The connecting plate 25 serves to fixedly connect the annular chamber 21 and the pump body 1.

[0036] An L-shaped oil filling pipe 45 is fixedly connected to the outer side wall of the oil storage tank 44 near the upper end. An oil outlet pipe 12 is fixedly connected to the bottom surface of the oil storage tank 44. The bottom end of the oil outlet pipe 12 is fixedly connected to a transverse pipe 13. A pipe plug 14 is inserted near the middle of the transverse pipe 13. Conical connecting plugs 15 are fixedly connected to both ends of the pipe plug 14.

[0037] The lubricating oil can be added into the oil storage tank 44 through the L-shaped oil filling pipe 45.

[0038] Two flow cavities 16 are opened on the inner side wall of the transverse pipe 13. Fixed plates 18 are fixedly connected to both ends of the transverse pipe 13 near the inner side wall. A first spring 17 is fixedly connected between the fixed plate 18 and the conical connecting plug 15. Diverging pipes 19 are fixedly connected to both ends of the transverse pipe 13. A collecting pipe 20 is fixedly connected between the ends of the two diverging pipes 19 far from the transverse pipe 13. The end of the collecting pipe 20 far from the diverging pipe 19 is arranged inside the annular chamber 21. A one-way valve 1 is arranged on the outer side wall of the collecting pipe 20 near the annular chamber 21.

[0039] The one-way valve 1 can prevent the lubricating oil inside the annular chamber 21 from flowing back into the collecting pipe 20.

[0040] An activity ring 23 is sleeved inside the annular chamber 21. A number of rotating blades 24 are fixedly connected to the outer side wall of the activity ring 23. A ring groove is penetrated on the inner side wall of the annular chamber 21. A number of connecting plates 25 are inserted into the ring groove. One end of the connecting plate 25 is fixedly connected to the outer side wall of the transmission shaft 8, and the other end is fixedly connected to the inner side wall of the activity ring 23. A number of spray pipes 22 are fixedly connected to the outer side wall of the annular chamber 21.

[0041] When using this vertical vacuum pump, the motor 5 drives the connecting ring 6 to rotate through the output shaft 7, which drives the driving wheel 9 to rotate through the belt 10, and then drives the transmission shaft 8 to rotate. The other end of the transmission shaft rotates in the pump body 1 through the bearing 47, so that the vacuum pump works. During operation, the pump body 1 and the pump body 2 vibrate. The oil storage tank 44 and the transverse pipe 13 in the vibration lubrication mechanism 42 follow the vibration, and the pipe plug 14 arranged inside vibrates. It moves left and right inside the transverse pipe 13 in cooperation with the first spring 17, and repeatedly moves from inside the transverse pipe 13 to inside the two flow cavities 16. When the pipe plug 14 and the conical connecting plugs 15 installed at both ends thereof move into the flow cavity 16, the lower end of the oil outlet pipe 12 is no longer blocked. The lubricating oil inside the oil storage tank 44 flows into the transverse pipe 13 through the oil outlet pipe 12 under the action of gravity, and flows into the two shunt pipes 19 through the position between the pipe plug 14 and the flow cavity 16, and then flows into the annular bin 21 through the collecting pipe 20. At the same time, the connecting plate 25 rotates with the transmission shaft 8, so as to drive the movable ring 23 to rotate, and the rotating blade 24 rotates with the movable ring 23, which can stir the lubricating oil entering the annular bin 21, avoid the lubricating oil from depositing at the bottom of the annular bin 21 under the action of gravity, resulting in uneven oil output. The lubricating oil entering the annular bin 21 can be continuously sprayed onto the surface of the bearing 47 through the spray pipe 22 for lubrication. Through the above operations, when the vertical vacuum pump works and generates vibration, the bearing 47 is continuously lubricated, so that the transmission shaft 8 rotates more smoothly, avoiding affecting the normal operation of the vertical vacuum pump.

[0042] The overheat lubrication mechanism 43 includes a processing box 26 and an arc-shaped heat conduction bin 40. The processing box 26 is arranged above the motor 5, and the arc-shaped heat conduction bin 40 is fixedly connected to the outer side wall of the motor 5. At the positions near the bottom ends of the two side walls of the processing box 26, support frames 48 are fixedly connected, and the bottom ends of the two support frames 48 are fixedly connected to the bottom plate 1.

[0043] A storage box 34 is inserted at the bottom end inside the processing box 26, and both the storage box 34 and the inside of the arc-shaped heat conduction bin 40 are filled with mercury 46. A square connecting short pipe 41 is fixedly connected to the outer wall of the top of the arc-shaped heat conduction bin 40, and the arc-shaped heat conduction bin 40 is communicated with the storage box 34 through the square connecting short pipe 41.

[0044] The arc-shaped heat conduction bin 40 is closely attached to the motor 5 and can absorb the heat generated when the motor 5 works, and the mercury 46 can expand when heated, so as to cooperate with the subsequent work of extruding the rubber oil storage bin 32.

[0045] On both inner walls of the processing box 26, at positions close to the middle, there are fixed mounting plates 29. Inside the processing box 26 and at the upper surface positions of the two groups of mounting plates 29, there is inserted a push plate 30. Between the upper surface of the push plate 30 near the four corners and the inner top of the processing box 26, there are connected second springs 31. Between the upper surface of the push plate 30 and the inner top of the processing box 26, there is arranged a rubber oil storage bin 32. On the outer wall of the top of the processing box 26, there is fixedly connected a communicating pipe 28 and an oil injection pipe 27. One end of the communicating pipe 28 is fixedly connected to the rubber oil storage bin 32, and the other end is arranged inside the annular bin 21. On the outer wall of the communicating pipe 28 near one end of the annular bin 21, there is arranged a second one-way valve. On the outer wall of the oil injection pipe 27, there is arranged a third one-way valve.

[0046] Among them, the oil injection pipe 27 can not only be used to add lubricating oil to the rubber oil storage bin 32, but also supplement the air required when the rubber oil storage bin 32 is squeezed and then rebounds. The third one-way valve can prevent the oil inside the rubber oil storage bin 32 from flowing out from the inside of the oil injection pipe 27. Similarly, the second one-way valve can prevent the lubricating oil inside the annular bin 21 from flowing back into the rubber oil storage bin 32 through the communicating pipe 28.

[0047] On the outer wall of the top of the storage box 34, there is fixedly connected a square connecting long pipe 33. On both inner walls of the square connecting long pipe 33, at positions close to the bottom end, there are fixedly connected bearing plates 37. Between the top outer wall of the bearing plate 37 and the inner top of the square connecting long pipe 33, there is fixedly connected a limiting rod 36. Outside the limiting rod 36, there is sleeved a movable plate 38. On the top outer wall of the movable plate 38, there is fixedly connected a push rod 35. The upper end of the push rod 35 is fixedly connected to the push plate 30. On the outer wall of the push rod 35, at a position close to the upper end, there is fixedly connected a support plate 39. And one end of the support plate 39 away from the push rod 35 is fixedly connected to the bottom surface of the push plate 30.

[0048] Among them, the bearing plate 37 plays a role in supporting and connecting the limiting rod 36. The support plate 39 can reinforce the position between the push rod 35 and the push plate 30, so that when the push rod 35 pushes the push plate 30 upward, it can be more stable.

[0049] Specifically, when the motor 5 works for a long time and heat is generated on its surface, the heat is dissipated through the heat sink 49. Part of the heat is absorbed and dissipated by each arc-shaped heat conducting bin 40. The absorbed heat makes the mercury 46 inside the arc-shaped heat conducting bin 40 heat up, and gradually transmits the heat to the inside of the storage box 34 through the square connecting short pipe 41, so that the mercury 46 inside the storage box 34 heats up and expands, and flows into the square connecting long pipe 33, thereby making the movable plate 38 move upward along the limiting rod 36. The push rod 35 follows the movable plate 38 to move upward, thereby driving the push plate 30 to move upward, squeezing the rubber oil storage bin 32. The second spring 31 is compressed, and the lubricating oil inside it flows out through the communicating pipe 28 into the annular bin 21, and then is sprayed out from the spray pipe 22 onto the bearing 47 through the same principle to lubricate the bearing 47.

[0050] Further explanation: For the above-mentioned fixed connection, unless otherwise clearly specified and limited, it should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are conventional means well-known to those skilled in the art.

[0051] As mentioned above, it is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
