Description

Technical Field

[0001] This invention relates to the field of wet mills, and particularly to a tiltable automatic feed and discharge wet mill and a wet milling process. Background Technology

[0002] Wet milling is a grinding process conducted in a liquid medium (such as alcohol and forming agents). Alcohol, as a solvent, effectively removes oil and impurities from the powder surface, ensuring the stability of subsequent forming processes. Compared to dry milling, wet milling reduces dust generation and lowers the temperature during the grinding process, thus preventing oxidation or phase transformation of the alloy powder due to overheating. Simultaneously, wet milling allows for better contact and interaction between the grinding media (such as grinding balls) and the alloy powder, improving grinding efficiency. The liquid medium not only serves as a grinding carrier but also provides cooling, lubrication, and dispersion, helping to maintain the uniformity and stability of the alloy powder.

[0003] In the field of wet grinding of fine materials such as metal powders, inclined wet mills are widely used because they can automate the feeding and discharging process by changing the tilt angle of the cylinder. These machines typically require a filter disc at the discharge port to prevent grinding media (such as grinding balls) from being discharged with the slurry. However, the filter disc structure in the prior art has the following significant drawbacks:

[0004] Traditional fixed filter discs can block materials from entering the cylinder during the feeding stage. Operators need to manually disassemble or remove the filter screen, which not only increases labor intensity but also prolongs equipment downtime and seriously restricts the pace of continuous production.

[0005] Some improved solutions use a rotatable filter disc, but rely on an independent drive motor or cylinder to control the rotation. Such designs require additional power units, increasing the size of the equipment and manufacturing costs.

[0006] When the cylinder tilts downward to discharge material, the mixture of slurry and grinding balls creates a violent impact on the filter disc. Traditional rotary filters lack an effective locking mechanism and are prone to accidental deflection under impact, causing grinding balls to escape or reducing filtration efficiency. Summary of the Invention

[0007] This invention provides a tiltable automatic feed and discharge wet mill and a wet milling process, which can solve the following problems existing in the prior art:

[0008] 1) Traditional fixed filter discs will block the material from entering the cylinder during the feeding stage. Operators need to manually disassemble or remove the filter screen, which not only increases labor intensity but also prolongs equipment downtime and seriously restricts the continuous production rhythm.

[0009] 2) Relying on an independent drive motor or cylinder to control the tilting, this type of design requires an additional power unit, increasing the size of the equipment and manufacturing costs;

[0010] 3) When the cylinder tilts downward to discharge material, the mixture of slurry and grinding balls creates a violent impact on the filter disc. Traditional rotary filter screens lack an effective locking mechanism and are prone to accidental deflection under impact, causing grinding balls to escape or reducing filtration efficiency.

[0017] Preferably, a positioning cylinder is provided on the cylinder body, and a water-cooling cavity can be formed between the cylinder body and the positioning cylinder. A water inlet and outlet pipe is also connected to the end of the cylinder body away from the material inlet and outlet cylinder. The water inlet and outlet pipe is connected to the water-cooling cavity through a water-cooling channel for cooling the wet grinding cylinder.

[0018] Preferably, the adjustment module includes an adjustment shaft fixedly arranged on both sides of the filter disc, the adjustment shaft being rotatably connected to the cylinder wall of the material inlet / outlet cylinder, and the other end of the adjustment shaft being fixed to the first gear;

[0019] The material inlet and outlet cylinders are provided with arc-shaped racks on both sides for meshing with the first gear, and the arc-shaped racks are fixed on the support box.

[0020] Preferably, an arc-shaped baffle is fixedly arranged inside the material inlet / outlet cylinder, and the arc-shaped baffle is in contact with the filter disc and located on the side closer to the cylinder opening.

[0021] Preferably, the inner wall of the material inlet / outlet cylinder is provided with a sealing ring that fits against the filter disc.

[0022] Preferably, a sealing cover is provided at the inlet of the material inlet / outlet cylinder, and two sets of limiting frames are symmetrically fixedly arranged on the sealing cover. A positioning shaft is fixedly arranged between the two sets of limiting frames, and a second gear is fixedly arranged on the positioning shaft. The two ends of the positioning shaft pass through the limiting frames and are rotatably connected to the U-shaped frame.

[0023] The positioning seat is equipped with an adjusting electric cylinder, the driving end of which is fixed to the U-shaped frame. The end of the positioning seat away from the cylinder is also equipped with a straight rack for meshing with the second gear.

[0024] A wet grinding process for a tiltable automatic feed and discharge wet mill, applied to the aforementioned tiltable automatic feed and discharge wet mill, includes the following steps:

[0025] Adjust the hydraulic cylinder to drive the wet grinding cylinder to rotate around the support shaft, so that the cylinder opening angle for material to enter and exit the cylinder is tilted upward, and the material to be wet-ground and the wet grinding medium are added into the wet grinding cylinder;

[0026] Adjust the hydraulic cylinder to drive the wet grinding cylinder back to a horizontal position;

[0027] The rotating module drives the wet grinding cylinder to rotate, so as to perform wet grinding on the material;

[0028] Adjust the oil cylinder to tilt the cylinder opening downwards to discharge the wet-ground material.

[0029] This invention provides a tiltable automatic feed and discharge wet mill, which has the following beneficial effects:

[0030] 1) This invention proposes a tiltable automatic feeding and discharging wet mill, which drives the filter disc to rotate 90° by changing the tilt angle of the cylinder, and physically limits it by an arc-shaped baffle during the discharge stage. This design deeply couples the movement of the filter disc with the core movement of the equipment (tilt angle adjustment), thereby avoiding additional driving requirements from the root. At the same time, the dynamic sealing problem is solved by the elastic compensation structure of the sealing ring.

[0031] 2) By setting up two sets of adjusting cylinders, when it is necessary to add the material to be ground into the wet grinding cylinder, the present invention drives the wet grinding cylinder to rotate around the support shaft by adjusting the cylinder, so that the angle of the cylinder opening for material inlet and outlet is tilted upward, so as to facilitate the addition of the material to be wet ground into the wet grinding cylinder; correspondingly, when the wet grinding is completed and the wet grinding slurry needs to be discharged, the present invention can adjust the angle of the cylinder opening for material inlet and outlet to tilt downward by adjusting the cylinder, so as to facilitate the discharge of the wet grinding slurry from the cylinder opening, thereby achieving the effect of automatic feeding and discharging, and the wet grinding efficiency is higher;

[0032] 3) The present invention limits the lower half of the filter disc by using an arc-shaped baffle. Even if the lower half of the filter disc is impacted by grinding balls and slurry, the filter disc will not deflect due to the blocking effect of the arc-shaped baffle on the lower half of the filter disc. Accordingly, the filter disc can only rotate in one direction towards the drive of the adjusting shaft.

[0033] 4) By setting a sealing ring, this invention can improve the sealing effect between the filter disc and the material inlet / outlet cylinder. On the other hand, when the filter disc rotates, the sealing ring can buffer the contraction, avoiding interference between the filter disc and the cylinder wall and the phenomenon of not being able to deflect. In addition, since the sealing ring has a certain elasticity, it can position the filter disc and prevent free deflection when the first gear and the arc rack are in a non-meshing state.

[0044] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0045] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a tiltable automatic feeding and discharging wet grinding mill, including a wet grinding cylinder 1, with a material inlet and outlet cylinder 102 rotatably arranged on one side of the wet grinding cylinder 1; specifically, in the process of grinding alloy powder, the material to be ground and the wet grinding media can be added to the wet grinding cylinder 1 through the material inlet and outlet cylinder 102, and the wet grinding media and the grinding balls in the wet grinding cylinder 1 can achieve the wet grinding treatment of the material.

[0046] It should be noted that the wet grinding media in this embodiment can be ethanol, water, hexane solvent or gasoline, etc. This embodiment does not limit the specific type of wet grinding media, as long as it meets the actual wet grinding requirements of the material.

[0047] In this embodiment, a positioning seat 301 is fixedly arranged on the material inlet / outlet cylinder 102, and a support shaft is fixedly arranged at both ends of the positioning seat 301. The other end of the support shaft is rotatably connected to the support box 2. Adjusting cylinders 201 are rotatably arranged on both sides of the support box 2. A positioning plate 202 is fixedly arranged on the wet grinding cylinder 1, and the driving end of the adjusting cylinder 201 is rotatably connected to the positioning plate 202. It can be noted that by setting two sets of adjusting cylinders 201, when it is necessary to add material to be ground into the wet grinding cylinder 1, this embodiment can drive the wet grinding cylinder 1 to rotate around the support shaft by adjusting the cylinders 201, so that the cylinder opening angle of the material inlet / outlet cylinder 102 is tilted upwards (see reference...). Figure 8 This facilitates the addition of the material to be wet-milled into the wet milling cylinder 1; correspondingly, when the wet milling is completed and the slurry needs to be discharged, this embodiment can adjust the downward tilting angle of the material inlet / outlet of the cylinder 102 by adjusting the hydraulic cylinder 201 (see reference). Figure 7 This allows the wet-milled slurry to be discharged from the cylinder opening, thus achieving automatic feeding and discharging, resulting in higher wet milling efficiency.

[0048] In addition, the positioning plate 202 is also equipped with a rotating module, which is used to drive the wet grinding cylinder 1 to rotate. Specifically, in the process of wet grinding the material, this embodiment can drive the wet grinding cylinder 1 to rotate through the rotating module to achieve the effect of material turning and grinding.

[0049] Please refer to Figure 7 As a further embodiment, the wet grinding cylinder 1 includes a cylinder body 104;

[0050] Please see Figures 1-5 A limiting seat 206 is rotatably sleeved on the side of the cylinder 104 away from the material inlet / outlet cylinder 102. The limiting seat 206 is fixed to the positioning plate 202 through the connecting frame 204. The rotating module includes a protective shell 205 fixed on the positioning plate 202. A servo motor is fixedly arranged in the protective shell 205. A positioning cylinder 103 is fixedly sleeved on the cylinder 104. A sprocket mechanism 203 is fixedly arranged on the positioning cylinder 103. The output end of the servo motor is connected to the positioning cylinder 103 through a chain and the sprocket mechanism 203. It can be noted that when the material is wet-grinding, the servo motor in this embodiment drives the positioning cylinder 103 to rotate through the chain and the sprocket mechanism 203. The positioning cylinder 103 synchronously drives the cylinder 104 to rotate, thereby realizing the wet grinding of the material.

[0051] Accordingly, in this embodiment, a positioning cylinder 103 is provided on the cylinder 104, and a water-cooled cavity can be formed between the cylinder 104 and the positioning cylinder 103. A water inlet / outlet pipe 101 is also connected to the end of the cylinder 104 away from the material inlet / outlet cylinder 102. The water inlet / outlet pipe 101 is connected to the water-cooled cavity through a water-cooling channel to replenish cooling water into the water-cooled cavity for cooling the wet grinding cylinder 1. It should be noted that this water-cooling structure is existing technology, and this embodiment does not limit its specific structure and principle.

[0052] As a further solution in this embodiment, please refer to Figures 4-6 After wet grinding, in order to prevent the grinding balls from being discharged along with the slurry, a filter disc 5 is embedded in the material inlet / outlet cylinder 102 during the slurry discharge process; the filter disc 5 is connected to the adjustment module that drives its rotation; specifically, during discharge, the grinding balls and slurry can be filtered through the filter disc 5.

[0053] It should also be noted that, in the initial state, the filter disc 5 in this embodiment is adjusted to be coaxial with the material inlet / outlet cylinder 102 by adjusting the module, so that the filter disc 5 can filter the grinding balls in the slurry during discharge to prevent the grinding balls from being discharged. Correspondingly, when it is necessary to add material into the material inlet / outlet cylinder 102, the filter disc 5 is adjusted to rotate 90 degrees by adjusting the module to facilitate feeding.

[0054] In this embodiment, when the material to be ground is added to the cylinder 104 through the material inlet / outlet cylinder 102, in order to avoid the filter disc 5 affecting the entry of the material, the adjustment module includes an adjustment shaft 606 fixedly arranged on both sides of the filter disc 5. The adjustment shaft 606 is rotatably connected to the cylinder wall of the material inlet / outlet cylinder 102, and the other end of the adjustment shaft 606 is fixed to the first gear 4. Arc-shaped racks 607 for meshing with the first gear 4 are respectively arranged on both sides of the material inlet / outlet cylinder 102. The arc-shaped racks 607 are fixed. On the supporting housing 2; it can be explained that, initially, the first gear 4 and the arc-shaped rack 607 are in a non-meshing state. When the adjusting cylinder 201 tilts upward at the opening angle of the material inlet / outlet cylinder 102 for feeding, as the material inlet / outlet cylinder 102 deflects upward, it can synchronously drive the first gear 4 to move through the adjusting shaft 606. The first gear 4 then meshes with the arc-shaped rack 607. During the meshing process, the first gear 4 drives the filter disc 5 to rotate 90 degrees through the adjusting shaft 606 (see reference). Figure 6 To facilitate feeding, when adjusting the oil cylinder 201 adjusts the material inlet / outlet cylinder 102 to be horizontal, the filter disc 5 rotates back to the vertical position.

[0055] Furthermore, when the adjusting cylinder 201 tilts downward at the angle of the material inlet / outlet cylinder 102, the first gear 4 does not mesh with the arc-shaped rack 607, and the first gear 4 will not rotate, allowing the filter disc 5 to perform normal filtration.

[0056] Furthermore, when the adjusting cylinder 201 tilts downwards at the angle of the material inlet / outlet cylinder 102, the grinding balls and slurry will exert an impact force on the lower half of the filter disc 5. To prevent the filter disc 5 from automatically flipping under the impact, please refer to... Figures 4-6 An arc-shaped baffle 501 is fixedly arranged inside the material inlet / outlet cylinder 102. The arc-shaped baffle 501 is in contact with the filter disc 5 and is located on the side closer to the cylinder opening. It can be explained that in this embodiment, the arc-shaped baffle 501 limits the lower half of the filter disc 5. Even if the lower half of the filter disc 5 is impacted by the grinding balls and slurry, the arc-shaped baffle 501 blocks the lower half of the filter disc 5, so that the filter disc 5 will not deflect. Accordingly, the filter disc 5 can only rotate in one direction towards the drive of the adjusting shaft 606.

[0057] In this embodiment, in order to improve the sealing performance between the filter disc 5 and the wall of the material inlet / outlet cylinder 102, a sealing ring 502 that fits against the filter disc 5 is provided on the inner wall of the material inlet / outlet cylinder 102. Specifically, by setting the sealing ring 502, on the one hand, the sealing effect between the filter disc 5 and the material inlet / outlet cylinder 102 can be improved; on the other hand, when the filter disc 5 rotates, the sealing ring 502 can play a buffering and shrinking role, avoiding interference between the filter disc 5 and the cylinder wall during rotation, thus preventing the filter disc 5 from being unable to deflect. In addition, since the sealing ring 502 has a certain elasticity, it can play a positioning role for the filter disc 5, preventing the first gear 4 and the arc-shaped rack 607 from being in a non-meshing state and causing free deflection.

[0058] Please see Figures 3-5 During normal wet grinding, in order to seal the inlet and outlet of the material inlet and outlet cylinder 102, a sealing cover 3 is provided at the inlet and outlet of the material inlet and outlet cylinder 102. Two sets of limiting frames 602 are symmetrically fixed on the sealing cover 3, and a positioning shaft 603 is fixedly arranged between the two sets of limiting frames 602. A second gear 604 is fixedly arranged on the positioning shaft 603. The two ends of the positioning shaft 603 pass through the limiting frames 602 and are rotatably connected to the U-shaped frame 601. An adjusting electric cylinder 6 is fixedly arranged on the positioning seat 301. The drive end of the adjusting electric cylinder 6 is fixed to the U-shaped frame 601. At the end of 301 away from the cylinder 104, a straight rack 605 is also fixedly arranged for meshing with the second gear 604. Specifically, in the initial state, the sealing cover 3 is in the state of covering the opening of the material inlet / outlet cylinder 102. When it is necessary to feed or discharge materials, in this embodiment, the U-shaped frame 601 can be driven to move away from the cylinder 104 by adjusting the electric cylinder 6. When the sealing cover 3 moves to the point of separating from the material inlet / outlet cylinder 102, the second gear 604 drives the sealing cover 3 to deflect a certain angle away from the cylinder opening by meshing with the straight rack 605, so as to facilitate feeding or discharging materials.

[0059] A wet grinding process for a tiltable automatic feed and discharge wet grinding mill includes the following steps:

[0060] Please see Figures 1-4 S1, Adjusting the oil cylinder 201 drives the wet grinding cylinder 1 to rotate around the support shaft, so that the angle of the cylinder opening of the material entering and exiting the cylinder 102 is tilted upward, and the material to be wet ground and the wet grinding medium are added into the wet grinding cylinder 1.

[0061] S2. Adjust the oil cylinder 201 to drive the wet grinding cylinder 1 to reset to a horizontal state;

[0062] S3. The rotating module drives the wet grinding cylinder 1 to rotate in order to perform wet grinding on the material;

[0063] S4. Adjust the oil cylinder 201 to tilt the cylinder opening angle of the material inlet / outlet cylinder 102 downwards so as to discharge the material after wet grinding.

[0064] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
