Abstract
Description
Technical Field
[0001] This utility model relates to the field of wet ball mill technology, specifically to an experimental wet ball mill. Background Technology
[0002] A wet overflow ball mill mainly consists of a cylinder, end caps, main bearings, hollow journals, transmission gears, and a feeder. It typically grinds larger particles into smaller ones through a mixing and crushing device between the drums. Ball mills are suitable for grinding various ores and other materials and are widely used in mineral processing, building materials, and chemical industries. Currently, wet ball mills are also used in laboratories to pulverize materials for testing purposes.
[0003] However, in existing wet ball mills, the teeth of the gears wear due to prolonged meshing during operation. Lubricating oil needs to be added to the upper part of the gears to reduce wear. Currently, the common methods are automatic dripping or brushing. However, dripping causes oil droplets to splash and contaminate the equipment, and the drip holes are prone to clogging, requiring regular cleaning. Manual brushing is time-consuming, labor-intensive, and results in uneven lubrication, affecting the accuracy and efficiency of laboratory testing.
[0004] In view of this, we propose an experimental wet ball mill. Utility Model Content
[0005] The purpose of this invention is to provide a wet ball mill for laboratory use, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An experimental wet ball mill includes a grinding jar, on which a gear sleeve is fixedly installed. A transmission gear one and a transmission gear two are respectively meshed at both ends of the gear sleeve. A lubrication mechanism is provided on the transmission gear two. The lubrication mechanism includes a lubrication box, and a sponge is installed in the lubrication box through a replacement mechanism.
[0008] Preferably, the second transmission gear is rotatably connected inside the lubrication box, and the lubrication box and the gear sleeve do not contact each other. Both ends of the second transmission gear are fixedly connected to cams.
[0009] Preferably, an oil-immersed plate is fixedly installed inside the lubrication box, and a vibration frame is slidably installed inside the lubrication box near one end of the transmission gear. The vibration frame and the oil-immersed plate are elastically connected by a spring.

[0011] Preferably, the replacement mechanism includes a fixed frame, which is slidably connected to the vibration frame. The sponge is detachably installed inside the fixed frame. A sliding frame is fixedly installed at the top of the fixed frame. A sliding seat is slidably installed inside the sliding frame. An installation frame is fixedly installed at the top of the sliding seat.
[0012] Preferably, two mounting slots are provided through the lubrication box, one mounting slot is provided at the top of the lubrication box near the vibration frame, and the other mounting slot is provided at the bottom of the side of the lubrication box, and the mounting slots are slidably connected to the mounting frame.

[0014] By employing the above technical solution, this utility model provides an experimental wet ball mill that has at least the following beneficial effects:
[0015] (1) By setting up a ball mill jar, a gear sleeve, a transmission gear one, a transmission gear two and a lubrication mechanism, the gear sleeve, transmission gear one and transmission gear two are self-lubricated when the ball mill jar is working. The transmission gear two is lubricated by squeezing an oil-containing sponge. The lubricating oil is released in the form of immersion or micro-dropleting, rather than direct spraying, which completely eliminates oil droplet splashing. At the same time, there is no problem of nozzle clogging when the sponge is used for lubrication, which can reduce the maintenance frequency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-7 An experimental wet ball mill includes a base 3, a support frame 4 fixedly mounted on the base 3, a grinding jar 1 rotatably mounted inside the support frame 4, a gear sleeve 2 fixedly mounted on the grinding jar 1, a transmission gear 5 meshing with the gear sleeve 2, and a motor fixedly connected to the transmission gear 5. The motor drives the transmission gear 5 to rotate, and when the transmission gear 5 rotates, it drives the gear sleeve 2 to rotate through meshing, thereby causing the grinding jar 1 to rotate along the support frame 4, thus enabling the grinding jar 1 to operate.
[0030] A second transmission gear 6 is also meshed with the gear sleeve 2, and the second transmission gear 6 is symmetrically arranged relative to the first transmission gear 5, making the rotation of the gear sleeve 2 more stable and providing a certain degree of support. A lubrication mechanism 7 is provided between the second transmission gear 6 and the base 3, which is used to self-lubricate the second transmission gear 6 during operation. Lubrication is achieved by squeezing an oil-impregnated sponge 77, releasing the lubricating oil in the form of immersion or micro-drips rather than direct spraying, completely eliminating oil splashing. Furthermore, the sponge 77 lubrication method avoids nozzle clogging, reducing maintenance frequency. Simultaneously, any oil droplets and impurities that may be present during the lubrication of the second transmission gear 6 can be recovered, preventing contamination of the device.
[0031] Please see Figures 2-5 The lubrication mechanism 7 includes a lubrication box 71, which is fixedly mounted on the base 3. The lubrication box 71 has an inclined surface with an opening in the direction of the transmission gear 6. The transmission gear 6 is rotatably mounted within the opening of the inclined surface, and the inclined surface prevents the lubrication box 71 from contacting the gear sleeve 2, thus avoiding motion interference. The transmission gear 6 is rotatably connected to the lubrication box 71 via two round rods, and cams 72 are fixedly mounted on the other ends of the two round rods. This allows the transmission gear 6 to drive the cams 72 to rotate synchronously when it rotates.
[0032] An oil tank 73 is fixedly installed at the top of the lubrication box 71 for storing lubricating oil. An oil-immersing plate 74 is fixedly installed at the end of the lubrication box 71 away from the transmission gear 6, and the surface of the oil-immersing plate 74 is in contact with the sponge 77. The oil-immersing plate 74 is fixedly connected to and communicates with the oil tank 73. The oil-immersing plate 74 is used to immerse the lubricating oil in the oil tank 73 into the sponge 77, so that the sponge 77 is in a state of being full of lubricating oil, which facilitates the lubrication of the sponge 77.
[0033] The oil-immersed plate 74 is elastically connected to the vibrating frame 75 via a spring. The vibrating frame 75 is slidably connected to the lubrication box 71, allowing the vibrating frame 75 to move horizontally within the lubrication box 71. The vibrating frame 75 is fitted with a sponge 77 via a replacement mechanism 8, allowing for quick replacement of the sponge 77 and preventing damaged sponge 77 from affecting the self-lubricating effect.
[0034] An oil injection notch 76 is formed through the vibration frame 75. A part of the second transmission gear 6 is located within the oil injection notch 76, and there is contact between the sponge 77 and the second transmission gear 6, as well as contact between the cam 72 and the vibration frame 75. When the cam 72 rotates, it will squeeze the vibration frame 75, and the vibration frame 75 will displace along the lubrication tank 71. And under the elastic force of the spring, the vibration frame 75 is always in contact with the cam 72, thereby reciprocally squeezing and releasing the sponge 77, causing the lubricating oil in the sponge 77 to leach out, so that the lubricating oil uniformly infiltrates onto the second transmission gear 6, and through the meshing action between the gears, self-lubrication is carried out for the entire first transmission gear 5, second transmission gear 6 and gear sleeve 2.
[0035] It should be noted that there is a certain inclination angle between the vibration frame 75 and the oil-soaked plate 74 and the base 3, so that when the vibration frame 75 displaces, the second transmission gear 6 is always in contact with the sponge 77 to ensure the lubrication effect.
[0036] Please refer to Figures 6-7 , the replacement mechanism 8 includes a fixed frame 81. The fixed frame 81 is slidably connected to the vibration frame 75, and both sides inside the vibration frame 75 are in a "C" - shaped structure, which plays a role in limiting the fixed frame 81 and can prevent the fixed frame 81 from disengaging from the vibration frame 75 in the horizontal direction. The sponge 77 is detachably installed inside the fixed frame 81, including but not limited to bonding, clamping, magic - tape connection, etc., so that the sponge 77 can be quickly disassembled and replaced.
[0037] A sliding frame 82 is fixedly installed at the top of the fixed frame 81. A sliding seat 84 is slidably installed inside the sliding frame 82. The sliding seat 84 is in a "T" - shaped structure, and the length of the sliding seat 84 is the same as the width of the sponge 77. The "T" - shaped structure plays a limiting role, which can prevent the sliding frame 82 from disengaging from the sliding seat 84, and the sliding frame 82 can translate along the sliding seat 84 without affecting the operation of the vibration frame 75.
[0038] An installation frame 83 is fixedly installed at the top of the sliding seat 84. The installation frame 83 is slidably connected to the lubrication tank 71 through the installation groove 9, so that the installation frame 83 can be quickly disassembled and assembled.
[0039] There are two installation grooves 9. One installation groove 9 is opened at the position near the top of the lubrication tank 71 close to the vibration frame 75 for the quick replacement of the sponge 77. The other installation groove 9 is opened at the position near the bottom on one side of the lubrication tank 71 for the reuse of the replaced sponge 77 to absorb the waste oil and impurities in the lubrication tank 71.
[0040] A wet ball mill for experiments, its working principle is:
[0041] The motor drives the transmission gear 5 to rotate. When the transmission gear 5 rotates, it drives the gear sleeve 2 to rotate through meshing, thereby driving the ball mill jar 1 to rotate along the support frame 4, thus enabling the ball mill jar 1 to work.
[0042] When gear sleeve 2 is working, it drives transmission gear 6 to rotate through meshing. The rotation of transmission gear 6 causes cam 72 to rotate synchronously. When cam 72 rotates, it squeezes vibrating frame 75, causing it to move along the lubrication box 71. Under the elastic force of the spring, vibrating frame 75 remains in contact with cam 72, thus reciprocatingly squeezing and releasing sponge 77. This allows the lubricating oil inside sponge 77 to seep out, ensuring the lubricating oil evenly wets transmission gear 6. The meshing action between the gears provides self-lubrication for the entire transmission gear 5, transmission gear 6, and gear sleeve 2. It is important to note that vibrating frame 75 and oil-immersing plate 74 are both set at a slight angle to the base 3, ensuring that transmission gear 6 remains in contact with sponge 77 during the displacement of vibrating frame 75, thus guaranteeing effective lubrication. Furthermore, when lubricating oil is squeezed out of sponge 77, it can be replenished through oil-immersing plate 74.
[0043] When the sponge 77 needs to be replaced, the mounting bracket 83 is pulled out of the mounting slot 9. The sliding bracket 82 at the bottom of the mounting bracket 83 engages with the fixed bracket 81, causing the mounting bracket 83 to move and the fixed bracket 81 to move synchronously. This allows the sponge 77 to detach from the lubrication box 71. The replacement of the sponge 77 is then completed by installing the new sponge 77 into the lubrication box 71. The replacement mechanism 8, after replacement, can be inserted into the bottom of the lubrication box 71 through the mounting slot 9 for the recovery of waste oil and impurities.
