Description

Technical Field

[0001] This utility model relates to the field of grinding and processing technology, specifically to an adjustable speed type vibrating ball mill. Background Technology

[0002] In the field of material grinding and processing technology, the oscillating ball mill is widely used in chemical, mining, building materials and other industries because it can achieve efficient grinding of materials through the combined motion of oscillation and vibration. The adjustable speed oscillating ball mill is a powder processing equipment that combines oscillation motion and vibration, and can change the grinding intensity and efficiency by adjusting the speed. It is mainly used to grind solid materials (such as ores, chemical raw materials, ceramic powders, etc.) to micron or even nanometer fineness.

[0003] In real life, the grinding cylinders of existing equipment are mostly placed at a fixed tilt angle or horizontally. The feeding of materials and grinding balls, and the removal of the finished products after grinding, require manual assistance in handling or dumping. The operation process is complicated, which not only increases the labor intensity, but also easily leads to material spillage or damage to the grinding cylinder due to improper operation. In addition, some materials may remain on the inner wall of the grinding cylinder due to factors such as static electricity and adsorption force. Long-term accumulation may lead to accelerated wear and tear on the equipment. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable speed type vibrating ball mill, which can effectively solve the problems of poor material loading and unloading and residual material cleaning in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides an adjustable speed type vibrating ball mill, including: a support structure, a driving mechanism on the support structure, and a grinding mechanism above the support structure;

[0007] The support structure includes a support frame, a first fixing frame is fixed to the upper end of the support frame, a gas pumping device is fixed to the upper end of the first fixing frame, and a second fixing frame is symmetrically fixed to the support frame. An electric telescopic rod is rotatably connected to the support frame below the second fixing frame near the gas pumping device.

[0008] Preferably, the drive mechanism includes two support plates, one of which is fixed to the upper end of the second fixed frame on the same side, and the other support plate is rotatably connected to the upper end of the second fixed frame on the same side. The support plate is rotatably connected to the output ends of the two second fixed frames. A lifting ring housing is fixed to the upper end of the support plate, and a rolling bearing is fixed inside the lifting ring housing. A drive shaft is fixedly connected to the inner wall of the rolling bearing. A drive shaft fixed to the lifting ring housing is provided above the second fixed frame. A motor is fixed to the other lifting ring housing. Sealing plates are provided on the sides of the two drive shafts that are close to each other. One sealing plate is fixedly connected to the output end of the motor, and the other sealing plate is fixedly connected to the output end of the second electric telescopic rod. A connecting ring is rotatably connected to the drive shaft on the side close to the motor.

[0009] Preferably, the output end of the gas pumping device is connected to the connecting ring.

[0010] Preferably, the grinding mechanism includes a sealed grinding cylinder fixed to a sealing plate, an arc-shaped ring fixed to the inner wall of the sealed grinding cylinder, a discharge groove opened on the end face of the arc-shaped ring, and a spraying component fixed inside the sealed grinding cylinder.

[0011] Preferably, the spraying assembly includes multiple sealing tubes fixed inside a sealing grinding cylinder, the diameter of the multiple sealing tubes gradually decreasing from the outside to the inside, a baffle fixed inside the sealing tube, an airbag fixed on the baffle, multiple spray nozzles arrayed at one end of the sealing tube near the arc-shaped ring, and a connecting pipe connecting two adjacent sealing tubes.

[0012] Preferably, one of the connecting pipes is connected to the connecting ring by a pipe.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] The rotation of the sealed grinding cylinder can be controlled by an electric telescopic rod, facilitating the feeding and discharging of materials and grinding balls. The reverse movement of the electric telescopic rod tilts the grinding cylinder, allowing materials to be automatically discharged along the arc-shaped discharge chute, reducing manual intervention and simplifying operation. Furthermore, the gas pumping device supplies gas to the sealed pipe of the spraying assembly through a connecting ring and connecting pipe. When the gas is sprayed out through the spray nozzle, it can blow off residual materials adsorbed on the inner wall of the sealed grinding cylinder, ensuring that subsequent grinding materials are not contaminated. This is especially suitable for continuous processing of multiple batches and varieties of materials. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example: Refer to Figures 1 to 5 An adjustable speed type vibrating ball mill includes: a support structure 1, a drive mechanism 2 on the support structure 1, and a grinding mechanism 3 above the support structure 1.

[0025] To further explain, the following settings are implemented to facilitate loading and unloading: Figure 2 As shown, the support structure 1 includes a support frame 11, a fixing frame 12 is fixed at the upper end of the support frame 11, a gas pumping device 13 is fixed at the upper end of the fixing frame 12, a fixing frame 2 14 is also symmetrically fixed on the support frame 11, and an electric telescopic rod 15 is provided below the fixing frame 2 14 near the gas pumping device 13 and rotatably connected to the support frame 11.

[0026] To further explain, the following settings are made for better operation of the components within the drive unit, such as... Figure 3 As shown, the drive mechanism 2 includes two support plates 21. One support plate 21 is fixed to the upper end of the second fixed frame 14 on the same side, and the other support plate 21 is rotatably connected to the upper end of the second fixed frame 14 on the same side. The support plate 21 is rotatably connected to the output ends of the two fixed frames 14. A lifting ring housing 22 is fixed to the upper end of the support plate 21. A rolling bearing 23 is fixed inside the lifting ring housing 22. A drive shaft 24 is fixedly connected to the inner wall of the rolling bearing 23. A drive shaft 24 is fixed to the lifting ring housing 22 above the second fixed frame 14. A motor 25 is fixed to the other lifting ring housing 22. A sealing plate 27 is provided on the side of the two drive shafts 24 that are close to each other. One sealing plate 27 is fixedly connected to the output end of the motor 25, and the other sealing plate 27 is fixedly connected to the output end of the electric telescopic rod 26. A connecting ring 28 is rotatably connected to the drive shaft 24 on the side close to the motor 25. The output end of the gas pumping device 13 is connected to the connecting ring 28.

[0027] To further explain, the following settings are required to complete the grinding process: Figure 4 As shown, the grinding mechanism 3 includes a sealed grinding cylinder 31 fixed on the sealing plate 27. An arc-shaped ring 32 is fixed on the inner wall of the sealed grinding cylinder 31. A discharge groove 33 is opened on the end face of the arc-shaped ring 32. A spraying component 34 is fixed inside the sealed grinding cylinder 31.

[0028] To further explain, the following settings are made to clean the material remaining in the sealed grinding cylinder 31, such as... Figure 5 As shown, the spraying assembly 34 includes multiple sealing tubes 341 fixed inside the sealing grinding cylinder 31. The diameter of the multiple sealing tubes 341 gradually decreases from the outside to the inside. A baffle 342 is fixed inside the sealing tube 341, and an airbag 343 is fixed on the baffle 342. Multiple spray nozzles are arrayed at one end of the sealing tube 341 near the arc-shaped ring 32. A connecting pipe 344 connects two adjacent sealing tubes 341. One of the connecting pipes 344 is connected to the connecting ring 28 by a pipe.

[0029] The working principle of this utility model is as follows: Before grinding, the grinding balls and the material to be ground need to be placed into the sealed grinding cylinder 31 simultaneously. It should be noted that in the initial state, the electric telescopic rod 26 is in a retracted state, making the port of the sealed grinding cylinder 31 near the electric telescopic rod 26 open. To facilitate the placement of the material and grinding balls into the sealed grinding cylinder 31, the electric telescopic rod 15 can be activated to retract it. Under the action of the connecting rod, the two electric telescopic rods 15 will drive the sealed grinding cylinder 31 to rotate upward through the support plate 21 and the sealing plate 27, so that the sealed grinding cylinder 31... With the port of 1 facing upwards for easy placement of materials, the electric telescopic rod 15 and the sealing grinding cylinder 31 are returned to their positions. The electric telescopic rod 26 is then activated to push the sealing plate 27 toward the sealing grinding cylinder 31 until the sealing plate 27 and the sealing grinding cylinder 31 come into contact and seal the cylinder. In fact, starting the motor 25 can drive the sealing grinding cylinder 31 to rotate through the sealing plate 27. The two rolling bearings 23 and the transmission shaft 24 work together to ensure that the rotation of the sealing grinding cylinder 31 is relatively stable and will not jam at high speeds, thus ensuring the grinding effect of the device.

[0030] After grinding is completed, activate the electric telescopic rod 26 to reset the sealing plate 27. Then, activate the electric telescopic rod 15 again to extend it, which will push the sealed grinding cylinder 31 to rotate downwards. The grinding balls and materials inside the sealed grinding cylinder 31 will fall automatically downwards along the discharge chute 33 under the action of gravity. Powder adsorbed on the inner wall of the sealed grinding cylinder 31 due to compression will remain. At this time, activate the gas pumping device 13 to introduce filtered air into the connecting ring 28. The air will enter multiple sealing pipes 341 through the connecting pipe 344, and then flow into the sealed grinding cylinder 31 through multiple spray nozzles, blowing away the powder adsorbed on the inner wall of the sealed grinding cylinder 31 and cleaning up the material remaining in the sealed grinding cylinder 31 as much as possible to prevent it from affecting subsequent grinding work.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
