Description

Technical Field

[0001] This invention relates to the field of lubricant grinding pretreatment technology, specifically to a grinding pretreatment apparatus for preparing open gear lubricants. Background Technology

[0002] Gear drives are divided into three types: open, semi-open, and closed. Open gear drives do not have dust covers or housings and are mainly used in simple mechanical equipment.

[0003] In the process of preparing lubricating oil, powdered additives are added to crude oil and stirred evenly. Since open gear lubricating oil needs to have good adhesion, the additives are slowly added to the crude oil to ensure that the additives can be distributed in the crude oil more quickly and evenly.

[0004] Some raw materials in additives need to be pre-treated, such as graphite and molybdenum disulfide used for heavy loads. The raw materials in block or small particle form need to be ground into powder of appropriate particle size. The current method is to grind the raw materials into powder in advance, store the powder, and take it out when needed. However, the storage conditions of powdered additives are extremely harsh. If the storage conditions are not right (such as too high temperature, too high humidity, pressure, etc.), clumping may occur. Adding clumped powder to crude oil will directly reduce the quality of lubricating oil. Summary of the Invention

[0005] The technical problem of the present invention is to provide a grinding pretreatment device for preparing open gear lubricant, in which the additive raw materials are ground and used immediately, and the rotation speed of the grinding section can be adjusted in real time according to the weight of the powder on the scattering section, thereby reducing the powder residence time, reducing the influence of external factors on the powder, and improving the quality of the lubricant.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grinding pretreatment apparatus for preparing open gear lubricant, comprising a pretreatment tank and a mixing tank, wherein the pretreatment tank comprises:

[0011] The drive mechanism, installed inside the barrel, is used to drive the rotation of the scattering section and the grinding section;

[0012] The speed control mechanism, installed between the spreading section and the grinding section, can adjust the rotation speed of the grinding section and the powder discharge speed according to the height of the spreading section.

The driving mechanism drives the grinding part to rotate continuously through the two swing components alternately.

[0014] Each of the aforementioned swing components includes:

[0015] The swing arm is mounted on the speed regulating mechanism in the middle, and its outer end is used to drive the grinding part to rotate.

[0016] The adjusting shaft is slidably mounted on the side wall via a sliding groove and the bottom is equipped with a speed regulating mechanism; the speed regulating mechanism changes the pivot point position of the swing arm, adjusts the swing amplitude of the swing arm, and adjusts the rotation speed of the grinding part by moving the adjusting shaft.

[0017] A synchronizing element is disposed between the rocker arm and the grinding part, with its inner end rotatably disposed at the outer end of the rocker arm and capable of rotating around the axis of the grinding part, intermittently driving the grinding part to rotate;

[0018] The inner ends of the two swing arms are slidably provided with an eccentric shaft through a sliding groove, and an eccentric component is installed at the bottom of the eccentric shaft on the drive mechanism.

[0019] As a further aspect of the present invention, the inner end of the grinding part is provided with circumferentially arrayed tooth grooves, and the synchronizing components all include:

[0020] The inner end of the timing frame is rotatably mounted on the outer side of the swing arm;

[0021] The limiting shaft is installed at the bottom of the timing frame to limit the radial movement of the timing frame;

[0022] The slide rail is installed inside the barrel and slides in conjunction with the limit shaft;

[0023] The synchronizing pawl is rotatably mounted on the synchronizing frame via a torsion spring, and can engage with the tooth groove to drive the grinding part to rotate.

[0024] As a further aspect of the present invention, the driving mechanism includes:

[0025] The drive shaft is mounted in the barrel by a bracket. The drive shaft is axially slidably connected to the scattering part by a key and is used to drive the scattering part and the eccentric part to rotate simultaneously.

[0026] The drive motor is installed inside the barrel and drives the drive shaft to rotate via a transmission belt.

[0027] As a further embodiment of the present invention, there are two speed regulating mechanisms, and each speed regulating mechanism includes:

[0028] The mounting plate is installed at the bottom of the adjusting shaft, and a return spring is installed between it and the barrel body;

[0029] The speed control frame is axially slidable with the barrel body and is used to drive the mounting plates on both sides to move in opposite directions.

[0030] The crossbar is rotatably mounted inside the barrel. The scattering section moves the speed control frame via the crossbar, changing the position of the mounting plate.

[0031] As a further embodiment of the present invention, the scattering part is rotatably provided with a rotating ring, and two connecting rods are fixedly provided at the top of the rotating ring.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] In this invention, the grinding section controls the speed of the grinding material, and the ground powder is directly mixed into the crude oil via the scattering section. This allows for the continuous and slow scattering of powder into the crude oil, enabling immediate use without long-term storage. This reduces the impact of external factors on the powder and improves the quality of the lubricating oil. Furthermore, the rotation speed of the grinding section is controlled by the amount of powder on the scattering section, thus controlling the grinding speed and the amount of powder added. This ensures that a small amount of powder is always present on the scattering section, enabling immediate use. The ground powder is immediately mixed with the crude oil, greatly reducing the time the powdered material is in contact with the outside environment. This further reduces the impact of external factors on the powdered material, preventing changes in its physical and chemical state, such as agglomeration, humidity changes, and oxidation. At the same time, it avoids interruptions in scattering or excessive scattering, which can lead to uneven scattering and prolonged mixing time. Attached Figure Description

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figures 1-12 The present invention provides a technical solution: a grinding pretreatment device for preparing open gear lubricant, comprising a pretreatment tank 1 and a mixing tank 7, wherein the pretreatment tank 1 comprises:

[0053] Barrel 2 is installed on top of mixing barrel 7;

[0054] The storage chamber 21 is located at the top of the barrel 2 and is used to store raw materials;

[0055] The grinding section 22 is rotatably disposed in the middle of the barrel 2 and is used to grind raw materials. A discharge port 23 is provided between the outer top of the grinding section 22 and the storage chamber 21.

[0056] The scattering section 24 is rotatably mounted at the bottom of the barrel 2 and its top is connected to the discharge port 23. The scattering section 24 is used to scatter raw material powder and its height can be adjusted according to the weight of the powder.

[0057] The drive mechanism 3 is installed inside the barrel 2 and is used to drive the scattering part 24 and the grinding part 22 to rotate;

[0058] The speed regulating mechanism 4 is installed between the spreading section 24 and the grinding section 22, and can adjust the rotation speed of the grinding section 22 according to the height of the spreading section 24, thereby adjusting the powder discharge speed.

[0059] Specifically, a suitable weight of raw material to be ground is weighed and poured into the storage chamber 21 from the top of the barrel 2. The raw material enters the grinding section 22 from the bottom of the storage chamber 21. Since the particle size of the raw material is much larger than that of the discharge port 23, the raw material cannot flow out of the discharge port 23 and accumulates between the grinding section 22 and the barrel 2. The grinding section 22 is rotated by the drive mechanism 3, and a relative displacement occurs between the grinding section 22 and the barrel 2. The large particles of raw material are continuously ground between the grinding section 22 and the barrel 2 until the particle size of the raw material is smaller than the opening size of the discharge port 23, and the small-particle raw material powder is formed. The powder material falls onto the spreading section 24 after passing through the discharge port 23 and being guided by the channel. The spreading section 24 rotates at a constant speed under the action of the drive mechanism 3. Under the action of centrifugal force, the powder material gradually moves from the inside to the outside of the spreading section 24 until it leaves the spreading section 24 and is scattered into the mixing tank 7. This allows large particles of raw material to be ground and immediately scattered into the mixing tank 7. The powder can be continuously and slowly scattered into the mixing tank 7, making it ready to use immediately without long-term storage. This reduces the impact of external factors on the powder material and improves the quality of the lubricating oil.

[0060] As the amount of powder on the scattering section 24 continuously increases (i.e., the amount of powder falling into the scattering section 24 through the discharge port 23 is greater than the amount of powder being sprayed out of the scattering section 24), the amount of powder on the scattering section 24 gradually increases. The scattering section 24 descends under the influence of the powder's gravity. The speed regulating mechanism 4 adjusts the rotation speed of the grinding section 22 in real time according to the descending height of the scattering section 24 (at this time, the rotation speed of the grinding section 22 is reduced). As the rotation speed of the grinding section 22 decreases, the grinding speed of the grinding section 22 on large particles decreases, and the amount of powder that can pass through the discharge port 23 decreases; combined with... Figure 10 and Figure 11 Since the rotational speed of the scattering section 24 is constant (in this embodiment, the constant rotational speed is achieved by controlling the output speed of the drive motor 32), the scattering speed remains unchanged. Simultaneously, the amount of powder falling into the scattering section 24 decreases due to the reduced rotational speed of the grinding section 22. Therefore, the amount of powder thrown out by the scattering section 24 is greater than the amount of powder fed in, thus gradually reducing the amount of raw material accumulated on the scattering section 24. Conversely, as the rotational speed of the grinding section 22 increases, the amount of raw material accumulated on the scattering section 24 gradually increases. In summary, by controlling the rotational speed of the grinding section 22 through the weight of the powder accumulated on the scattering section 24, the grinding speed and the increase in powder quantity on the scattering section 24 are indirectly controlled. This ensures that a small amount of powder is always present on the scattering section 24, enabling immediate use after grinding. The ground powder is immediately mixed with crude oil, greatly reducing the time the powdered raw material is in contact with the outside world. This further reduces the impact of external factors on the powdered raw material, preventing changes in its physical and chemical state, such as agglomeration, humidity changes, and oxidation. Simultaneously, it avoids interruptions in scattering or excessive scattering, which could lead to uneven scattering and prolonged mixing time.

[0061] As a further embodiment of the present invention, two swing components 5 are installed between the grinding part 22 and the driving mechanism 3. The swing components 5 are arranged in a circular array around the axis of the barrel 2. The driving mechanism 3 drives the grinding part 22 to rotate continuously through the two swing components 5 alternately.

[0062] Each swing component 5 includes:

[0063] The swing arm 51 is mounted on the speed regulating mechanism 4 in the middle, and the outer end is used to drive the grinding part 22 to rotate.

[0064] The adjusting shaft 52 has a side wall that slides with the rocker arm 51 via a groove, and a speed regulating mechanism 4 is installed at the bottom. The speed regulating mechanism 4 changes the pivot position of the rocker arm 51, adjusts the swing amplitude of the rocker arm 51, and adjusts the rotation speed of the grinding part 22 by moving the adjusting shaft 52.

[0065] Synchronizing element 6 is disposed between the swing arm 51 and the grinding part 22, with its inner end rotatably disposed at the outer end of the swing arm 51, and is able to rotate around the axis of the grinding part 22, intermittently driving the grinding part 22 to rotate;

[0066] The inner ends of the two swing arms 51 are slidably provided with an eccentric shaft 54 ​​through a sliding groove, and an eccentric component 53 is installed at the bottom of the eccentric shaft 54 ​​on the drive mechanism 3.

[0067] For details, see Figure 4 , Figure 5 and Figure 8 As the drive mechanism 3 rotates, the eccentric component 53 drives the inner end of the swing rod 51 to move through the eccentric shaft 54. The adjusting shaft 52 limits the middle part of the swing rod 51, causing the outer end of the swing rod 51 to swing. The outer end of the swing rod 51 drives the synchronizing component 6 to rotate around the axis of the grinding part 22. The synchronizing component 6 intermittently drives the grinding part 22 to rotate. The synchronizing component 6 on the other side resets. The two synchronizing components 6 alternately drive the grinding part 22 to rotate, realizing the continuous rotation of the grinding part 22.

[0068] As the powder on the scattering section 24 continues to increase, the adjusting shaft 52 is moved outward from the barrel 2 via the speed regulating mechanism 4. (See below) Figure 9, the swing amplitude of the swing rod 51 decreases. Since the driving mechanism 3 drives the eccentric member 53 to rotate at a constant speed, the time t of a single swing interval at the inner end of the swing rod 51 is the same (i.e., the time taken for the eccentric shaft 54 to rotate from the solid line state to the dotted line state). As the adjustment shaft 52 moves outward from the barrel body 2, the swing amplitude of the swing rod 51 decreases, and the moving distance of the outer end of the swing rod 51 is shortened (i.e., s2 < s1. According to the formula v = s÷t, v1*t = s1, v2*t = s2. Since s2 < s1, therefore, v2*t < v1*t, that is, v2 < v1). The moving distance of the outer end of the swing rod 51 within the same time decreases as the moving distance of the adjustment shaft 52 moving outward from the barrel body 2 increases. Therefore, the moving speed of the synchronizing member 6 at the outer end of the swing rod 51 decreases, so that the more powder accumulates on the throwing part 24, the slower the rotating speed of the grinding part 22; on the contrary, the less powder accumulates on the throwing part 24, the faster the rotating speed of the grinding part 22. Furthermore, the grinding speed of the grinding part 22 is adjusted in real time according to the weight of the material falling on the throwing part 24, reducing the time of powder accumulation and residence; thereby reducing the influence of external factors on the raw material in powder state.

[0069] As a further solution of the present invention, tooth grooves 61 arranged in a circumferential array are provided at the inner end of the grinding part 22. The synchronizing members 6 all include:

[0070] A synchronizing frame 62, the inner end of which is rotatably arranged on the outer side of the swing rod 51;

[0071] A limiting shaft 63, installed at the bottom of the synchronizing frame 62 for restricting the radial movement of the synchronizing frame 62;

[0072] A slide rail 64, installed inside the barrel body 2 and slidably matched with the limiting shaft 63;

[0073] A synchronizing pawl 65, rotatably arranged on the synchronizing frame 62 through a torsion spring and capable of cooperating with the tooth groove 61 to drive the grinding part 22 to rotate; the synchronizing pawl 65 is attached to the inner side wall of the grinding part 22 through a torsion spring;

[0074] Specifically, referring to Figure 2 and Figure 3 , the outer end of the swing rod 51 drives the synchronizing frame 62 to move, and the limiting shaft 63 on the synchronizing frame 62 moves synchronously therewith. The slide rail 64 radially limits the synchronizing frame 62 through the limiting shaft 63, so that the synchronizing frame 62 can only rotate axially. The synchronizing frame 62 drives the synchronizing pawl 65 to rotate, and the synchronizing pawl 65 enters the tooth groove 61 and drives the grinding part 22 to rotate through the tooth groove 61;

[0075] When the swing arm 51 rotates in the opposite direction, the synchronizing pawl 65 moves in the opposite direction with the synchronizing frame 62 and rotates into the synchronizing frame 62, while disengaging from the tooth groove 61. The two synchronizing frames 62 rotate in the opposite direction. When one of the synchronizing frames 62 drives the grinding part 22 to rotate through the synchronizing pawl 65, the other synchronizing frame 62 drives the synchronizing pawl 65 to rotate in the opposite direction with the grinding part 22; thus realizing that a single swing component 5 intermittently drives the grinding part 22 to rotate.

[0076] As a further aspect of the present invention, the driving mechanism 3 includes:

[0077] The drive shaft 31 is mounted inside the barrel 2 by a bracket. The drive shaft 31 is axially slidable with the scattering part 24 by a key and is used to drive the scattering part 24 and the eccentric part 53 to rotate simultaneously.

[0078] The drive motor 32 is installed inside the barrel 2 and drives the drive shaft 31 to rotate via a transmission belt; the transmission belt includes, but is not limited to, the combination of chain and gear, and the combination of belt and pulley.

[0079] For details, see Figure 7 The output shaft of the drive motor 32 drives the drive shaft 31 to rotate via the transmission belt. The drive shaft 31 drives the scattering part 24 to rotate via the key, thereby scattering the powder material. It also drives the eccentric part 53 to rotate, thereby rotating the eccentric shaft 54, thus realizing the oscillation of the oscillating component 5 and the rotation of the grinding part 22.

[0080] As a further embodiment of the present invention, there are two speed regulating mechanisms 4, and each speed regulating mechanism 4 includes:

[0081] Mounting plate 41 is installed at the bottom of adjusting shaft 52, and a return spring 42 is installed between it and barrel body 2;

[0082] The speed regulating frame 43 is axially slidable with the barrel body 2 and is used to drive the mounting plates 41 on both sides to move in opposite directions.

[0083] The crossbar 44 is rotatably installed inside the barrel 2. The scattering part 24 drives the speed regulating frame 43 to move through the crossbar 44, changing the position of the mounting plate 41.

[0084] For details, see Figure 4 , Figure 5 , Figure 7 and Figure 12 When the scattering section 24 descends, the scattering section 24 drives the speed regulating frame 43 to descend via the crossbar 44, causing the mounting plate 41 to move in opposite directions to both sides (i.e., the mounting plates 41 move away from each other). The adjusting shaft 52 moves synchronously with the mounting plate 4, thereby changing the pivot point position of the swing arm 51, adjusting the swing amplitude of the swing arm 51, and adjusting the rotation speed of the grinding section 22.

[0085] As a further embodiment of the present invention, the scattering part 24 is rotatably provided with a rotating ring 46, and two connecting rods 45 are fixedly provided on the top of the rotating ring 46. The two ends of each crossbar 44 are rotatably provided with the barrel body 2 and the connecting rod 45 respectively. The middle part of the crossbar 44 and the end near the connecting rod 45 are provided with a sliding groove. The middle part of the crossbar 44 is slidably provided with the bottom of the speed regulating frame 43 through the sliding groove.

[0086] For details, see Figure 4 , Figure 5 , Figure 7 and Figure 12 The rotating ring 46 can move up and down with the powder-spreading part 24 fixed to it. When the powder-spreading part 24 descends under the action of powder gravity, the rotating ring 46 descends and drives the crossbar 44 to contact one end of it (i.e., the end that is in contact with it) via the connecting rod 45. Figure 12 The horizontal bar 44 (near the arrow end) descends, and the entire horizontal bar 44 revolves around the hinge point with the barrel 2 (i.e. Figure 12 The end of the crossbar 44 furthest from the arrow rotates, and the middle of the crossbar 44 drives the speed regulating frame 43 to descend along the axis of the barrel 2 via a slide groove. The speed regulating frame 43 passes through the inclined grooves at both ends (see...). Figure 5 The drive mounting plate 41 moves to both sides of the barrel 2, and the mounting plate 41 drives the adjustment shaft 52 to move synchronously, thereby changing the pivot point of the swing arm 51, adjusting the swing amplitude of the swing arm 51 and adjusting the rotation speed of the grinding part 22; at the same time, the crossbar 44 is a force-saving lever, which can amplify the gravitational potential energy of the powder raw material and transmit it to the speed regulating frame 43, increasing the sensitivity of the speed adjustment of the grinding part 22.

[0087] As a further embodiment of the present invention, the scattering part 24 includes a rotating part 25 and a lifting part 26. The rotating part 25 is rotatably disposed at the bottom of the barrel body 2. The rotating part 25 and the lifting part 26 are slidably disposed between the rotating part 25 and the lifting part 26 and are provided with an elastic element 27. The rotating ring 46 rotates relative to the lifting part 26.

[0088] Specifically, when the material falls onto the scattering part 24, the powder first falls onto the lifting part 26, causing the lifting part 26 to descend relative to the rotating part 25 and stretch the elastic element 27. The elastic element 27 is used to reset the lifting part 26, and at the same time, it can lift the speed regulating mechanism 4 upward through the lifting part 26 and the rotating ring 46, so that the crossbar 44 can be reset, while sharing the pressure of the reset spring 42.

[0089] As a further embodiment of the present invention, the top of the grinding part 22 is provided with a guide slope and a grinding slope, and the width between the guide slope and the barrel 2 gradually decreases from top to bottom.

[0090] Specifically, the material is fed from top to bottom, with the particle size gradually decreasing until the powder particle size meets the requirements, and then falls from the discharge port 23 into the spreading section 24.

[0091] As a further embodiment of the present invention, a differential is provided between the drive shaft 31 and the eccentric member 53; the differential adjusts the speed difference between the grinding part 22 and the scattering part 24 so that both the grinding part 22 and the scattering part 24 can be adjusted to a suitable speed range.
