Description

Technical Field

[0001] This invention relates to the field of storage container technology, and more particularly to a lubricating oil storage device with smooth discharge. Background Technology

[0002] In mechanical equipment, lubricating oil is required to ensure that the friction between relatively moving parts is small. At the end of production, the lubricating oil needs to be stored in a storage tank to prevent it from being contaminated with dirt or absorbing water.

[0003] A search revealed Chinese patent publication number CN218113754U, which discloses a constant-temperature storage device for lubricating oil, comprising a movable frame, a body, and a pump. The device is characterized by: the body being bolted to the outer wall of its top end; the pump being bolted to one side of the outer wall of the body; a liquid chamber being formed inside the body; a constant-temperature plate being provided on the outer wall of the liquid chamber; an insulation layer being provided on the outer wall of the constant-temperature plate; a nozzle being rotatably connected to the outer wall of the body; the nozzle being pipe-connected to the liquid chamber; and an air cooler being provided on the outer wall of the top end of the body, which is pipe-connected to the constant-temperature plate.

[0004] The above-mentioned patent has the following shortcomings: it uses gravity to drain the oil, but since the lubricating oil has a relatively low temperature and a certain viscosity when it is not in use, relying solely on gravity to drain the oil will result in a low draining rate and make it impossible to accurately control the amount of oil drained.

[0005] Therefore, the present invention proposes a lubricating oil storage device with smooth discharge. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a lubricating oil storage device with smooth discharge.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A lubricating oil storage device with smooth discharge includes a tank body and a tank cover fixedly installed on the top of the tank body.

[0009] The bottom of the tank is connected to an outlet valve via a discharge pipe, the top of the tank cover is connected to an inlet valve via a feed pipe, and a valve-type piston is threadedly connected inside the tank. An electric motor is fixedly installed on the top outer wall of the tank cover, and the output shaft of the electric motor is connected to the valve-type piston via a telescopic shaft.

[0010] The valve-type piston includes a piston plate, a main material inlet longitudinally opened inside the piston plate, and a main material baffle that slides on the inner wall of the piston plate and cooperates with the main material inlet. The outer wall of the piston plate is connected to the inner wall of the tank through a Luwen convex ring.

[0011] Preferably: a rotating cylinder is rotatably connected inside the piston plate, the telescopic shaft is rotatably connected to the piston plate and fixedly connected to the rotating cylinder, and a drive rod is rotatably connected to the inner side wall of the rotating cylinder through a hinge rod, and the other end of the drive rod is rotatably connected to the inner wall of the main material-permeable baffle through a hinge rod.

[0012] Throughout the entire stroke of the drive rod, the extension line of the drive rod never intersects the axis of the rotating drum.

[0013] Furthermore: the inner wall of the piston plate is longitudinally provided with a plurality of auxiliary material passages corresponding to the number of main material passages, and the inner wall of the piston plate is slidably connected with an auxiliary material passage baffle that cooperates with the auxiliary material passages. The outer wall of the auxiliary material passage is rotatably connected with a connecting rod, and the other end of the connecting rod is rotatably connected to the side wall of the main material passage baffle.

[0014] Based on the aforementioned scheme: the top of the piston plate is provided with a locking assembly corresponding to the number of main material through baffles. The locking assembly includes a bracket fixedly installed on the top of the piston plate and a friction block slidably connected to the outside of the bracket via a guide slide rod. The other end of the guide slide rod is rotatably connected to a second connecting rod, and the other end of the second connecting rod is rotatably connected to a second driving rod. The second driving rod is slidably connected to the bracket longitudinally, and a driving assembly is provided at the bottom of the second driving rod.

[0015] A limiting plate is fixedly installed on the outer wall of the guide slide rod, and the limiting plate is fastened to the same spring on the opposite side of the bracket.

[0016] A preferred embodiment of the aforementioned scheme is that the driving assembly includes a roller rotatably connected to the bottom of the second driving rod and two limiting grooves formed on the top of the main material-permeable baffle.

[0017] As a further aspect of the present invention: when the main material outlet is completely blocked by the main material outlet or when the main material outlet is completely opened by the main material outlet, the rollers roll and engage with the tops of the two limiting grooves respectively.

[0018] Meanwhile, the telescopic shaft is composed of multiple shaft cores and bushings. The shaft cores and bushings are slidably fitted by a gap through a flat key protrusion, and the shaft cores and bushings can only slide axially.

[0019] As a preferred embodiment of the present invention: an installation frame is fixedly installed on the inner wall of the bottom discharge port of the tank, a scraper assembly is rotatably connected to the inner wall of the installation frame, and multiple scrapers are fixedly installed on the outer wall of the scraper assembly, with the scrapers contacting and cooperating with the discharge pipe.

[0020] Meanwhile, the scraper assembly consists of an outer shaft and an inner shaft. The outer shaft is rotatably connected to the inner wall of the mounting bracket, and the inner shaft is fitted to the inner wall of the outer shaft through a key with two clearances. The bottom of the inner shaft is connected to the outer shaft through two springs.

[0021] As a preferred embodiment of the present invention: a clamp is fixedly installed on the top of the inner shaft, and a groove matching the clamp is provided at the bottom of the telescopic shaft.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The present invention, by setting a valve-type piston, utilizing the threaded connection between the valve-type piston and the tank body, and controlling the opening and closing of the main material outlet through the main material outlet baffle, allows the lubricating oil to be discharged more smoothly by using the valve-type piston as a whole to press down during oil discharge, and by using the height of the valve-type piston to accurately control the amount of oil discharged.

[0024] 2. This invention, by setting a drive rod and a rotating cylinder as driving transmission components, and in conjunction with the actual resistance of the sliding of the main material-through baffle relative to the piston plate and the sliding of the Luwen convex ring relative to the tank body, combined with the initial rotational inertia, cleverly achieves the integrated driving of the main material-through baffle and the main material-through port, as well as the rotational driving of the piston plate. This achieves the desired effect of the main material-through baffle first blocking and then the piston plate rotating and descending, and the main material-through baffle first opening and then the piston plate rotating and rising. It increases the tightness and synchronization of the connection between the movement of the device, while also reducing the power source layout, reducing costs, and facilitating volume optimization.

[0025] 3. In this invention, by setting an auxiliary material inlet and an auxiliary material inlet baffle, the cross-sectional area of ​​the flow channel for lubricating oil to flow from the top to the bottom of the valve piston during its ascent is increased, thereby reducing motion resistance and achieving energy saving. Furthermore, the auxiliary material inlet baffle is connected to the main material inlet baffle by a connecting rod, and its opening and closing are completely synchronized with the main material inlet baffle, further increasing the tightness and synchronization of the connection between the movement of the device, while also reducing the power source layout, lowering costs, and facilitating volume optimization.

[0026] 4. This invention, by setting a locking component, can achieve relative locking of the piston plate rotation when the main material through baffle changes state, ensuring the reliability of the main material through baffle state switching motion. It can also release the lock after the main material through baffle is at two position limits, ensuring that the resistance of the piston plate movement is small. Furthermore, for the relatively double-free open transmission when the telescopic shaft drives the main material through baffle state switching and piston plate rotation, this device cleverly utilizes the characteristic that the rotational resistance of the threaded pair is greater than the sliding resistance, combined with the large size and inertia of the piston plate itself, to achieve automatic control.

[0027] 5. The present invention, on the one hand, by setting a scraper, can prevent lubricating oil from sticking to the inner wall of the discharge pipe at the end of the oil discharge process. On the other hand, the rotational power of the scraper comes from the rotation of the telescopic shaft, which realizes transmission through the cooperation of the clamp and the groove. Thus, it can realize both the comprehensive power function and the requirement of scraping oil only at the end, saving the load in the first and middle stages of oil discharge and achieving energy saving effect.

Detailed Implementation

[0040] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0041] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0042] Example 1:

[0043] A lubricating oil storage device with smooth discharge, such as Figure 1-11 As shown, the device includes a tank body 1 and a tank cover 2 fixed to the top of the tank body 1 by bolts. The bottom of the tank body 1 is connected to an outlet valve 8 via a discharge pipe 7. The top of the tank cover 2 is connected to an inlet valve 4 via a feed pipe 5. A valve-type piston 9 is threadedly connected inside the tank body 1. An electric motor 3 is fixed to the top outer wall of the tank cover 2 by bolts. The output shaft of the electric motor 3 is driven to the valve-type piston 9 via a telescopic shaft 6.

[0044] The valve piston 9 includes a piston plate 10, a main material inlet 14 longitudinally opened inside the piston plate 10, and a main material baffle 15 that is slidably fitted on the inner wall of the piston plate 10 and cooperates with the main material inlet 14. The outer wall of the piston plate 10 is connected to the inner wall of the tank body 1 through a Luwen convex ring 16.

[0045] When using this device, the inlet valve 4 can be opened to inject lubricating oil into the tank 1 through the feed pipe 5 for storage. When oil needs to be discharged, first determine the discharge volume Q, then start the motor 3 to drive the valve piston 9 to rotate through the telescopic shaft 6, thereby causing the valve piston 9 to move upward by h. During this process, the main material discharge baffle 15 slides into the inside of the piston plate 10. The main material discharge baffle 15 does not cooperate with the main material discharge port 14. The lubricating oil located at the top of the piston plate 10 will pass through the main material discharge port 14 to the bottom of the piston plate 10 until h = Q / S is satisfied, where S is the cross-sectional area of ​​the inner cavity of the tank 1, so that the main material discharge baffle 15 slides towards the main material discharge port 14 until the main material discharge port 14 is blocked. Then, start the motor 3 in reverse to drive the valve piston 9 to move downward, and at the same time open the outlet valve 8, so that the lubricating oil can be discharged from the outlet valve 8.

[0046] This device, by setting a valve-type piston 9, utilizes the threaded connection between the valve-type piston 9 and the tank body 1, and controls the opening and closing of the main material outlet 14 through the main material outlet baffle 15, so that when discharging oil, on the one hand, the valve-type piston 9 is used as a "piston" to press down as a whole, so that the lubricating oil is discharged more smoothly; on the other hand, the height of the valve-type piston 9 can also be used to precisely control the amount of oil discharged.

[0047] To solve the driver problem; such as Figure 3 As shown, a rotating cylinder 18 is rotatably connected inside the piston plate 10. The telescopic shaft 6 is rotatably connected to the piston plate 10 and fixedly connected to the rotating cylinder 18. The inner side wall of the rotating cylinder 18 is rotatably connected to a drive rod 17 via a hinge rod 19. The other end of the drive rod 17 is rotatably connected to the inner wall of the main material-passing baffle 15 via the hinge rod 19.

[0048] Furthermore, throughout the entire stroke of the drive rod 17, the extension line of the drive rod 17 never intersects the axis of the rotating drum 18.

[0049] Because the Luwen convex ring 16 and the tank body 1 are connected by a threaded pair, the resistance is relatively large when the threaded pair rotates relative to each other, while the resistance is relatively small when the main material through baffle 15 slides relative to the piston plate 10. At the same time, because the piston plate 10 is relatively large at the beginning of the start, it has a large moment of inertia. Therefore, when the telescopic shaft 6 drives the piston plate 10, it will first rotate relative to the piston plate 10, thereby driving the main material through baffle 15 to slide through the drive rod 17 until the main material through baffle 15 slides to the limit of its stroke. Only when the telescopic shaft 6 continues to rotate can it drive the piston plate 10 to rotate.

[0050] This device, by setting the drive rod 17 and the rotating drum 18 as the driving transmission components, and in conjunction with the actual resistance of the sliding of the main material through baffle 15 relative to the piston plate 10 and the sliding of the Luwen convex ring 16 relative to the tank body 1, combined with the rotational inertia of the initial start, cleverly realizes the coordinated driving of the main material through baffle 15 and the main material through port 14 and the rotational driving of the piston plate 10. It achieves the desired effect of the main material through baffle 15 first blocking and then the piston plate 10 rotating and descending, and the main material through baffle 15 first opening and then the piston plate 10 rotating and rising. It increases the tightness and synchronization of the connection between the movement of the device, while also reducing the power source layout, reducing costs, and facilitating volume optimization.

[0051] To solve the resistance problem; such as Figure 4 As shown, the inner wall of the piston plate 10 is longitudinally provided with a plurality of auxiliary material passages 12 corresponding to the number of main material passages 14, and the inner wall of the piston plate 10 is slidably connected with an auxiliary material passage baffle 13 that cooperates with the auxiliary material passages 12. The outer wall of the auxiliary material passages 12 is rotatably connected with a connecting rod 20, and the other end of the connecting rod 20 is rotatably connected to the side wall of the main material passage baffle 15.

[0052] As the entire valve piston 9 rises, the lubricating oil flows from the top to the bottom of the valve piston 9 at a constant speed. The larger the cross-sectional area of ​​the flow channel, the smaller the resistance to the rise of the valve piston 9.

[0053] This device, by setting up an auxiliary material inlet 12 and an auxiliary material inlet baffle 13, increases the cross-sectional area of ​​the flow channel for lubricating oil to flow from the top to the bottom of the valve piston 9 when it rises, thereby reducing motion resistance and achieving energy saving. Furthermore, the auxiliary material inlet baffle 13 is connected to the main material inlet baffle 15 through a connecting rod 20, and its opening and closing are completely synchronized with the main material inlet baffle 15, which further increases the tightness and synchronization of the connection between the movement of the device, while also reducing the power source layout, reducing costs, and facilitating volume optimization.

[0054] To address process stability issues; such as Figure 2 , 5 As shown in Figure 6, the top of the piston plate 10 is provided with a locking assembly 11 corresponding to the number of main material through baffles 15. The locking assembly 11 includes a bracket 21 fixed to the top of the piston plate 10 by bolts and a friction block 22 slidably connected to the outside of the bracket 21 by a guide slide rod 23. The other end of the guide slide rod 23 is rotatably connected to a connecting rod 26, and the other end of the connecting rod 26 is rotatably connected to a driving rod 27. The driving rod 27 is slidably connected to the bracket 21 in the longitudinal direction, and a driving assembly 28 is provided at the bottom of the driving rod 27.

[0055] The outer wall of the guide slide rod 23 is welded with a limiting plate 25, and the limiting plate 25 and the bracket 21 are fastened with the same spring 24.

[0056] The drive assembly 28 includes a roller 29 rotatably connected to the bottom of the drive rod 27 and two limiting grooves 30 opened on the top of the main material passage baffle 15. When the main material passage baffle 15 completely blocks the main material passage 14 or the main material passage baffle 15 completely opens the main material passage 14, the roller 29 rolls and engages with the top of the two limiting grooves 30 respectively.

[0057] When roller 29 engages with limiting groove 30, the relative position of roller 29 is lower, and limiting plate 25 moves inward under the elastic force of spring 24, thereby causing friction block 22 to separate from the inner wall of tank 1. When roller 29 does not engage with limiting groove 30, the relative position of drive rod 27 is higher, thereby causing guide slide rod 23 to move outward through connecting rod 26, thereby causing friction block 22 to contact and squeeze the inner wall of tank 1, increasing the rotational resistance of piston plate 10 relative to tank 1.

[0058] To solve the problems of telescopic extension and transmission, the telescopic shaft 6 is composed of multiple shaft cores 31 and bushings 32. The shaft cores 31 and bushings 32 are slidably fitted by a key protrusion 33, and the shaft cores 31 and bushings 32 can only slide axially.

[0059] The specific usage steps and working principle of this embodiment are as follows:

[0060] S1: Filling and storage: Open the inlet valve 4 and input the processed lubricating oil into the tank 1 for storage;

[0061] S2: Oil removal;

[0062] First, determine the oil discharge volume, and then determine the required rising distance of the valve piston 9 based on the cross-sectional area of ​​the inner cavity of the tank 1. Then, start the electric motor 3.

[0063] When the motor 3 is started, it transmits torque directly to the rotating drum 18 via the telescopic shaft 6. At this time, due to the relatively large friction between the threaded pair between the Luwen convex ring 16 and the tank body 1, and the inertia of the piston plate 10 itself, there will be a certain "impact force" during the initial start-up. This causes the telescopic shaft 6 to drive the rotating drum 18 to rotate relative to it, pulling the main material outlet baffle 15 from the state of blocking the main material outlet 14 to the state of opening the main material outlet 14, until the main material outlet 14 is fully opened. During this process, due to… Initially, the main material-through baffle 15 is in a blocked state. At this time, the drive rod 27 is in a relatively low position, and the friction block 22 is not in contact with the inside of the tank 1. Subsequently, when the main material-through baffle 15 is impacted and moves, the roller 29 rolls out from the limiting groove 30, so that the friction block 22 is tightly fitted with the inner wall of the tank 1 to prevent the piston plate 10 from rotating and to ensure the reliable opening of the main material-through baffle 15. After the main material-through baffle 15 is fully open, the roller 29 rolls to another limiting groove 30, and the friction block 22 is no longer in contact with the inner wall of the tank 1.

[0064] Continue to start the motor 3. At this time, since the main material conveying baffle 15 has moved to the limit position of its stroke and cannot move, the telescopic shaft 6 continues to rotate, which will drive the entire piston plate 10 to move upward until the piston plate 10 moves to the required height.

[0065] The motor 3 is quickly reversed, and the outlet valve 8 is opened at the same time. At this time, due to the relatively large friction of the threaded pair between the Luwen convex ring 16 and the tank body 1, and the inertia of the piston plate 10 itself, the telescopic shaft 6 will continue to apply "impact force" to the main material outlet baffle 15, causing the main material outlet baffle 15 to move in the direction of blocking the main material outlet 14. During the movement, the friction block 22 is tightly attached to the inner wall of the tank body 1 to ensure that the piston plate 10 does not rotate until the main material outlet baffle 15 completely blocks the main material outlet 14. At this time, the roller 29 cooperates with another limiting groove 30, and the friction block 22 does not contact the inner wall of the tank body 1.

[0066] Continue to start the motor 3 in reverse. At this time, since the main material conveying baffle 15 has moved to the limit position and cannot move, the telescopic shaft 6 continues to rotate, which will drive the entire piston plate 10 to move downward, squeezing the hydraulic oil and discharging it from the outlet valve 8.

[0067] This device, by setting a locking component 11, can relatively lock the rotation of the piston plate 10 when the main material conveying baffle 15 switches states, ensuring the reliability of the movement of the main material conveying baffle 15 during state switching. It can also release the lock after the main material conveying baffle 15 is at two extreme positions, ensuring that the resistance to the movement of the piston plate 10 is small. Furthermore, for the relatively double-free open transmission when the telescopic shaft 6 drives the main material conveying baffle 15 to switch states and the piston plate 10 to rotate, this device cleverly utilizes the characteristic that the rotational resistance of the threaded pair is greater than the sliding resistance, combined with the large size and inertia of the piston plate 10 itself, to achieve automatic control.

[0068] Example 2:

[0069] A lubricating oil storage device with smooth discharge, such as Figure 8-11 As shown, in order to further solve the problem of smooth material discharge, this embodiment makes the following improvements based on embodiment 1: A mounting bracket 35 is welded to the inner wall of the bottom discharge port of the tank 1. A scraper shaft assembly 34 is rotatably connected to the inner wall of the mounting bracket 35. Multiple scrapers 36 are welded to the outer wall of the scraper shaft assembly 34. The scrapers 36 are in contact with the discharge pipe 7. When the scrapers 36 rotate, they can scrape the inner wall of the discharge pipe 7, thereby preventing the lubricating oil from sticking to the inner wall of the discharge pipe 7 at the end of the oil discharge.

[0070] The scraper assembly 34 is composed of an outer shaft 37 and an inner shaft 38. The outer shaft 37 is rotatably connected to the inner wall of the mounting bracket 35. The inner shaft 38 is fitted with the inner wall of the outer shaft 37 through a key protrusion 40. The bottom of the inner shaft 38 is connected to the outer shaft 37 through a spring 39.

[0071] The top of the inner shaft 38 is welded with a clamp head 41, and the bottom of the telescopic shaft 6 is provided with a groove that matches the clamp head 41. The cross-section of the clamp head 41 and the groove can be in the shape of a "I", a "+", or a triangular, rectangular, or hexagonal structure. In this embodiment, a hexagonal structure is preferred.

[0072] In this embodiment, when the piston plate 10 descends to the final stage, the clamp 41 is inserted into the clamp slot. The rotation of the telescopic shaft 6 will also drive the inner shaft 38 to rotate, thereby driving the outer shaft 37 and the scraper 36 to rotate through the flat key protrusion 40. When the scraper 36 rotates, it can scrape the inner wall of the discharge pipe 7, thereby preventing the lubricating oil from sticking to the inner wall of the discharge pipe 7 at the end of the oil discharge stage.

[0073] This device, on the one hand, prevents lubricating oil from sticking to the inner wall of the discharge pipe 7 at the end of the oil discharge process by setting scraper 36. On the other hand, the rotation power of scraper 36 comes from the rotation of telescopic shaft 6, which is transmitted through the cooperation of chuck 41 and chuck slot. Thus, it can realize the comprehensive power function and also meet the needs of scraping oil only at the end, saving the load in the first and middle stages of oil discharge and achieving energy saving effect.

[0074] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
