Description

Technical Field

[0001] This invention relates to the field of storage equipment technology, and in particular to a lubricating oil storage device. Background Technology

[0002] Lubricating oil is a common lubricant. A lubricant is typically used between two relatively moving objects to reduce friction caused by contact. Storage tanks are used to store refined chemical substances such as acids, alkalis, alcohols, gases, and liquids. The storage of lubricating oil relies on these tanks. However, lubricating oil has a certain viscosity and tends to adhere to the inner wall of the tank. This can lead to incomplete drainage or require waiting longer for the oil adhering to the tank wall to slowly flow down, thus affecting efficiency.

[0003] To address this issue, a lubricating oil storage tank, such as the one with patent number CN221893736U, was developed. However, this equipment has several drawbacks. When the magnet is removed, the liquid level in the tank drops, and the scraper moves downwards under its own weight to scrape off the lubricating oil adhering to the inner wall of the tank. After the lubricating oil in the tank is drained, the cover needs to be opened and the scraper manually moved. Then, the scraper is suspended above the tank by magnetic connection between the magnet and the adsorption platform. Only then can new lubricating oil be injected into the tank below the scraper for storage. This method increases the difficulty of operation and can also cause workers' limbs to get covered in lubricating oil, making it difficult to clean later. Furthermore, it is difficult to scrape off and clean the lubricating oil adhering to the inner wall of the tank simply by moving the scraper downwards, so as to facilitate its drainage. Summary of the Invention

[0004] The purpose of this invention is to provide a lubricating oil storage device.

[0005] The technical problem of this invention is mainly solved by the following technical solution: A lubricating oil storage device includes a tank with a discharge pipe at the bottom, a jacket covering the outside of the tank, a connecting pipe between the upper and lower ends of the jacket, a counterweight mechanism inside the jacket, and a traction mechanism at the top of the tank with one end connected to the counterweight mechanism and the other end connected to a cleaning mechanism inside the tank. The inner wall of the jacket is provided with a slot for accommodating the heating tube; The traction mechanism includes a frame located at the top edge of the tank for mounting a pulley block, a traction rope being provided on the pulley block, and the two ends of the traction rope being connected to a counterweight mechanism and a cleaning mechanism, respectively. The cleaning mechanism includes a circular seat located inside the tank. A ring of mounting slopes is arranged around the bottom corners of the circular seat. Multiple sets of annular scrapers are arranged on the mounting slopes, wherein the diameter of the upper annular scraper is larger than that of the lower annular scraper. A conical groove is provided at the top of the circular seat. An installation groove is provided at the middle of the bottom of the circular seat. A material discharge port communicating with the installation groove is provided at the middle of the bottom of the groove. A cover plate is provided in the installation groove to seal the material discharge port. One end of the cover plate is hinged and fixed to the side wall of the installation groove. A spring I connected to the top of the cover plate is also provided on the top wall of the installation groove. The top of the tank is also equipped with a feeding mechanism that passes through a circular seat and a squeezing mechanism that is directly opposite the discharge port.

[0006] Preferably, the feeding mechanism includes a feeding pipe that passes through a circular seat, a solenoid valve is provided on the feeding pipe, a metal telescopic tube is provided at the top of the feeding pipe, the top end of the telescopic tube passes through the top wall of the tank, a box is provided at the top of the tank to cover the top end of the telescopic tube, and a feeding pipe connected to the top end of the telescopic tube is provided on the outside of the box.

[0007] Preferably, the extrusion mechanism includes a box located at the top of the tank, a metal plate suspended at the top of the box, a vertical rod passing through the top wall of the tank and facing the material discharge port at the bottom of the metal plate, a spring II sleeve on the vertical rod at the top of the tank, and an annular electromagnet located below the metal plate at the top of the tank.

[0008] Preferably, a solenoid valve is provided on the connecting pipe.

[0009] Preferably, a liquid storage chamber is formed between the jacket and the outer wall of the tank body, the counterweight mechanism is a ring-shaped mechanism and is sleeved on the tank body, the size of the counterweight mechanism is adapted to the size of the liquid storage chamber, the counterweight mechanism is located at the bottom of the liquid storage chamber, the connection between the bottom end of the connecting pipe and the side wall of the jacket is directly opposite the counterweight mechanism, the circular seat is located at the top of the tank body, and the size of the circular seat is adapted to the size of the opening inside the tank body.

[0010] Preferably, both the top wall of the jacket and the top wall of the tank are provided with through holes for the traction rope to pass through, and the size of the traction rope is adapted to the size of the through hole.

[0011] Preferably, the pulley block is provided with a rotating shaft that passes through the side wall of the frame and is driven by a motor.

[0012] Preferably, the vertical cross-section of the sidewall of the annular scraper is triangular.

[0013] Preferably, a receiving groove for installing spring I is provided on the top wall of the mounting groove.

[0014] The beneficial effects of this invention are: 1. This invention uses multiple sets of upper and lower annular scrapers to gradually scrape off and clean the lubricating oil on the inner wall of the tank to reduce its adhesion. Then, a circular seat is used to thoroughly scrape off and clean the remaining lubricating oil on the inner wall of the tank. This prevents the lubricating oil from creating huge resistance and affecting the movement when the circular seat is used to scrape off a large amount of lubricating oil adhering to the inner wall of the tank, and also prevents the scraping from being incomplete when the circular seat is used to scrape off a large amount of lubricating oil adhering to the inner wall of the tank at once.

[0015] 2. In this invention, new lubricating oil is injected into the tank below the circular seat through the feeding mechanism. Under the influence of the buoyancy of the lubricating oil gradually increasing in the tank, the circular seat slowly moves upward. At this time, the upward pulling force on the counterweight mechanism by the traction rope gradually decreases. Then, under the influence of gravity, the counterweight mechanism will slowly move downward in the liquid storage chamber. During the downward movement of the counterweight mechanism, the liquid in the liquid storage chamber below it is squeezed and injected into the liquid storage chamber above it through the connecting pipe. This facilitates the upward reset of the cleaning mechanism while injecting new lubricating oil into the tank below for storage. Attached Figure Description

Detailed Implementation

[0018] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] A lubricating oil storage device includes a tank 1 with a discharge pipe at the bottom, a jacket 2 wrapped around the outside of the tank 1, the upper and lower ends of the jacket 2 being connected by a connecting pipe 3, a solenoid valve being provided on the connecting pipe 3, a counterweight mechanism 4 being provided inside the jacket 2, and a traction mechanism 5 being provided at the top of the tank 1 with one end connected to the counterweight mechanism 4, and the other end of the traction mechanism 5 being connected to a cleaning mechanism 6 inside the tank 1. The inner wall of the jacket 2 is provided with a slot for accommodating the heating tube 7; The traction mechanism 5 includes a frame 51 located at the top edge of the tank 1 for mounting a pulley block 52. The pulley block 52 is provided with a rotating shaft that passes through the side wall of the frame 51 and is driven by a motor. The pulley block 52 is provided with a traction rope 53, and the two ends of the traction rope 53 are respectively connected to the counterweight mechanism 4 and the cleaning mechanism 6. The cleaning mechanism 6 includes a circular seat 61 located inside the tank 1. A ring of inclined mounting surfaces 62 is arranged around the bottom corner of the circular seat 61. Multiple sets of annular scrapers 63 are arranged on the inclined mounting surfaces 62, wherein the diameter of the upper annular scraper 63 is larger than the diameter of the lower annular scraper 63. Figure 2 , 3 As shown, the side wall vertical section of the annular scraper 63 is a triangular structure. The top of the circular seat 61 is provided with a conical groove 64. The bottom middle of the circular seat 61 is provided with an installation groove 65. The bottom middle of the groove 64 is provided with a discharge port 66 communicating with the installation groove 65. The installation groove 65 is provided with a cover plate 67 that seals the discharge port 66. One end of the cover plate 67 is hinged and fixed to the side wall of the installation groove 65. The top wall of the installation groove 65 is also provided with a spring I68 connected to the top of the cover plate 67. The inner top wall of the installation groove 65 is provided with a receiving groove 11 for installing the spring I68. The top of the tank body 1 is also provided with a feeding mechanism 8 that penetrates the circular seat 61 and a squeezing mechanism 9 that is directly opposite the discharge port 66.

[0020] The feeding mechanism 8 includes a feeding pipe 81 that passes through the circular seat 61. A solenoid valve is provided on the feeding pipe 81. A metal telescopic pipe 82 is provided at the top of the feeding pipe 81. The top end of the telescopic pipe 82 passes through the top wall of the tank 1. A box 83 is provided at the top of the tank 1 to cover the top end of the telescopic pipe 82. A feeding pipe 84 connected to the top end of the telescopic pipe 82 is provided on the outside of the box 83.

[0021] The extrusion mechanism 9 includes a box 91 located at the top of the tank 1. A metal plate 92 is suspended at the top inside the box 91. A vertical rod 93 is provided at the bottom of the metal plate 92, passing through the top wall of the tank 1 and facing the material discharge port 66. A spring II 94 is sleeved on the vertical rod 93 at the top of the tank 1. A ring electromagnet 95 is also provided at the top of the tank 1 below the metal plate 92.

[0022] In this embodiment, a liquid storage chamber is formed between the jacket 2 and the outer wall of the tank 1. The counterweight mechanism 4 is a ring-shaped mechanism and is sleeved on the tank 1. The size of the counterweight mechanism 4 is adapted to the size of the liquid storage chamber. The counterweight mechanism 4 is located at the bottom of the liquid storage chamber. The connection between the bottom end of the connecting pipe 3 and the side wall of the jacket 2 is directly opposite the counterweight mechanism 4. The circular seat 61 is located at the top of the tank 1. The size of the circular seat 61 is adapted to the size of the opening inside the tank 1.

[0023] In this embodiment, both the top wall of the jacket 2 and the top wall of the tank 1 are provided with through holes for the traction rope 53 to pass through, and the size of the traction rope 53 is adapted to the size of the through hole.

[0024] The method of using this invention is as follows: When the liquid storage chamber above the counterweight mechanism 4 is filled with liquid, the circular seat 61 floats on the surface of the lubricating oil level under the influence of the buoyancy of the liquid in the tank 1. The liquid in the storage chamber exerts a certain downward squeezing force on the counterweight mechanism 4. At the same time, under the influence of the weight of the counterweight mechanism 4 itself, the counterweight mechanism 4 is finally located at the bottom of the storage chamber. The counterweight mechanism 4 exerts an upward pulling force on the circular seat 61 through the traction rope 53. Finally, under the influence of the pulling force of the traction rope 53 and the buoyancy of the lubricating oil inside the tank 1, the circular seat 61 will float on the liquid surface at the top of the tank 1. At this time, the spring 168 pulls the cover plate 67, causing the cover plate 67 to rotate upward with the hinge between it and the side wall of the mounting groove 65 as the center, so that the cover plate 67 finally slides into the mounting groove 65 and seals the discharge port 66.

[0025] When it is necessary to drain the lubricating oil from tank 1, the bottom discharge pipe is opened to slowly drain the lubricating oil. As the liquid level in tank 1 slowly decreases, the circular seat 61 will also slowly move downwards within tank 1. At the same time, the solenoid valve on the connecting pipe 3 is opened, allowing the liquid at the top of the storage chamber to flow into the bottom of the storage chamber through the connecting pipe 3, reducing the squeezing pressure of the liquid in the storage chamber on the counterweight mechanism 4. Simultaneously, as the circular seat 61 moves downwards, the traction rope 53 exerts an upward pulling force on the counterweight mechanism 4, causing it to slowly move upwards. When it moves to the position above the bottom of the connecting pipe 3, the liquid at the top of the storage chamber is pressurized and flows into the storage chamber below the counterweight mechanism 4 through the connecting pipe 3. At this time, the liquid in the storage chamber below the counterweight mechanism 4 can exert an upward pushing force on the upward-moving counterweight mechanism 4, while the squeezing pressure of the liquid in the storage chamber at the top on the counterweight mechanism 4 gradually decreases. Ultimately, this makes it easier for the counterweight mechanism 4 to move upwards while reducing the indirect resistance it causes to the circular seat 61 during the downward movement.

[0026] As the circular seat 61 moves downward, it drives multiple sets of annular scrapers 63 to scrape off and clean the lubricating oil that may adhere to the inner wall of the tank 1. At this time, the multiple sets of annular scrapers 63 of different diameters at the top and bottom achieve the purpose of scraping off and cleaning the adhering lubricating oil in a multi-stage and gradual manner, so that the amount of lubricating oil adhering to the inner wall of the tank 1 gradually decreases. Finally, the circular seat 61 completely scrapes off and cleans the remaining lubricating oil on the inner wall of the tank 1. This achieves the purpose of gradually scraping off and cleaning the lubricating oil on the inner wall of the tank 1 by multiple sets of annular scrapers 63 at the top and bottom to reduce its adhesion, and then completely scraping off and cleaning the remaining lubricating oil on the inner wall of the tank by the circular seat 61. This prevents the lubricating oil from creating huge resistance and affecting its movement when only the circular seat 61 is used to scrape off and clean a large amount of lubricating oil adhering to the inner wall of the tank 1, and also prevents the circular seat 61 from scraping off a large amount of lubricating oil adhering to the inner wall of the tank at one time, which would result in incomplete scraping.

[0027] During the above process, the liquid in the storage chamber is heated by the heating pipe 7, so that the heat passes through the side wall of the tank 1 to give a preliminary heating effect on the lubricating oil adhering to the inner wall. This makes it easier for the downward-moving annular scraper 63 and circular seat 61 to scrape off and clean the lubricating oil on the inner wall of the tank 1. At the same time, under the influence of the movement of the counterweight mechanism 4, it drives the liquid in the storage chamber to flow through the connecting pipe 3. This allows the liquid in the storage chamber to flow so that the counterweight mechanism 4 can move, and also makes it easier for the liquid to fully contact the heating pipe 7 for heating.

[0028] During the aforementioned process, when the circular seat 61 moves downward, the telescopic tube 82 is stretched by the feed pipe 81, ensuring that it does not affect the movement of the circular seat 61. When new lubricating oil needs to be injected after the lubricating oil in the tank 1 has been drained, it is injected into the tank 1 below the circular seat 61 through the feed pipe 84, the telescopic tube 82, and the open feed pipe 81. Under the influence of the gradually increasing buoyancy of the lubricating oil in the tank 1, the circular seat 61 slowly moves upward. At this time, the upward pulling force exerted on the counterweight mechanism 4 by the traction rope 53 gradually decreases. Then, under the influence of gravity, the counterweight mechanism 4 slowly moves downward within the storage chamber. During the downward movement of the counterweight mechanism 4, the liquid in the storage chamber below it is squeezed and injected into the storage chamber above it through the connecting pipe 3. In the liquid chamber, as liquid is injected into the storage chamber above it, the downward squeezing force exerted on the counterweight mechanism 4 increases as the liquid volume gradually increases. This facilitates further driving the counterweight mechanism 4 to move downward within the storage chamber. During the above process, the motor 10 can drive the rotating shaft to rotate the pulley block 52. As the pulley block 52 rotates, it pulls the traction rope 53 to move. This causes the traction rope 53 to pull the circular seat 61 upward while reducing its pulling force on the counterweight mechanism 4, so that the counterweight mechanism 4 can move downward and the circular seat 61 can move upward. Alternatively, the traction rope 53 can pull the counterweight mechanism 4 upward while reducing its pulling force on the circular seat 61, so that the counterweight mechanism 4 can move upward and the circular seat 61 can move downward.

[0029] When the tank 1 is filled with a large amount of lubricating oil, the pulley block 52 can be rotated manually or by the motor 10. This will cause the pulley block 52 to rotate, which in turn moves the traction rope 53. At the same time, the traction rope 53 moves the circular seat 61 to the top of the tank 1, and the counterweight mechanism 4 moves to the bottom of the liquid storage chamber. Simultaneously, the solenoid valve on the connecting pipe 3 is closed. The upward-moving circular seat 61 will squeeze the telescopic pipe 82 to make it contract. At this time, lubricating oil can also be added to the tank 1 below the circular seat 61 through the feeding pipe 84, the telescopic pipe 82 and the feed pipe 81.

[0030] During the process described above, as the circular seat 61 moves upward, a small amount of lubricating oil that may remain on the inner wall of the tank 1 may be scraped onto the top of the circular seat 61. This scraped lubricating oil will flow along the inclined wall of the groove 64 to its bottom center and collect in the discharge port 66. When the circular seat 61 moves to the top of the tank 1, the electromagnet 95 is energized to exert a downward magnetic force on the metal plate 92. This causes the metal plate 92 to move downward while compressing the spring II 94. Simultaneously, the bottom end of the drive rod 93 moves downward and slides into the discharge port 66, pressing down on the cover plate 67. This causes the cover plate 67 to rotate downward with its hinge point with the side wall between it and the mounting groove 65 as the center, while also stretching the spring I 68. Finally, one end of the cover plate 67 moves from the mounting groove 65... As the lubricating oil in the groove 65 rotates downwards, the discharge port 66 opens, allowing the lubricating oil collected in the discharge port 66 to fall into the tank 1 below the circular seat 61 for recycling. After the lubricating oil in the discharge port 66 is drained, the electromagnet 95 is de-energized, and the spring II 94 extends, pushing the metal plate 92 upwards while simultaneously moving the vertical rod 93 upwards. As the cover plate 67 loses the squeezing action of the vertical rod 93, the spring I 68 contracts and pulls the cover plate 67, causing it to rotate upwards with the hinge between it and the side wall of the mounting groove 65 as the center. This allows the cover plate 67 to finally slide into the mounting groove 65 and seal the discharge port 66. Then, the feeding mechanism 8 can continuously inject lubricating oil into the tank 1 at the bottom of the circular seat 61, which then contacts the bottom of the circular seat 1 to provide an upward support.

[0031] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
