An electromagnetically heated stirring ball mill

Abstract

This utility model discloses an electromagnetically heated stirring ball mill, relating to the technical field of ball milling equipment. It includes a base, with a mounting seat and a tilting mechanism fixed to the top of the base. A ball mill jar is positioned between the mounting seat and the tilting mechanism. An electromagnetic heating mechanism is installed on the outer wall of the ball mill jar, and a vibration mechanism is installed at the bottom of the jar. The vibration mechanism includes a vibrating plate, which is located inside the ball mill jar. A guide rod is fixedly connected to the bottom of the vibrating plate, penetrating the bottom wall of the ball mill jar. The advantages are: after the material is ball-milled, the ball mill jar is tilted, causing the guide rod to move in a circular motion. When the ball mill jar reaches a certain angle, the guide rod and the extrusion mechanism compress each other. As the ball mill jar tilts, the guide rod, under the action of a spring, drives the vibrating plate to reciprocate. The vibrating plate impacts the inner wall of the ball mill jar, causing vibration in both the vibrating plate and the ball mill jar, resulting in more thorough material discharge. This eliminates the need for manual tapping of the ball mill jar, making it more convenient to use.

Description

Technical Field

[0001] This utility model relates to the field of ball milling equipment technology, and in particular to an electromagnetic heating and stirring ball mill. Background Technology

[0002] When the stirred ball mill is working, the main shaft drives the agitator to rotate at high speed, causing the grinding media to move irregularly. This chaotic and disordered movement will generate collisions, compressions, frictions, and shearing of the grinding media, thereby crushing and fine grinding the material. For the stirring and grinding of new building materials, the stirred ball mill can grind the raw materials of the building materials into finer particles.

[0003] For example, patent document CN222305963U discloses a lifting-type stirring ball mill. By placing the raw material and balls inside the stirring tank, the top plate is moved by the extension end of the hydraulic rod, and the top plate moves the stirring structure into the stirring tank. At this time, the stirring structure can stir the raw material and balls inside the stirring tank by rotating, so that the balls can perform ball milling on the raw material inside the stirring tank.

[0004] After the ball milling is completed, the mill jar usually needs to be turned over to pour out the ground material. However, some material will stick to the inner wall of the mill jar. In order to make the unloading more thorough, the mill jar needs to be manually tapped. The vibration of the mill jar will make the material discharge more completely. Since manual tapping is required for each unloading, it is not convenient to use. Utility Model Content

[0005] The purpose of this invention is to provide an electromagnetic heating stirring ball mill in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] An electromagnetically heated stirring ball mill includes a base, a mounting seat and a tilting mechanism fixed on the top of the base, a grinding jar disposed between the mounting seat and the tilting mechanism, an electromagnetic heating mechanism disposed on the outer wall of the grinding jar, a vibration mechanism disposed at the bottom of the grinding jar, the vibration mechanism including a vibrating plate disposed inside the grinding jar, a guide rod fixedly connected to the bottom of the vibrating plate, the guide rod penetrating the bottom wall of the grinding jar, a limit plate fixedly connected to the guide rod, a spring fixedly connected between the top of the limit plate and the bottom of the grinding jar, a pressing mechanism for pressing the guide rod disposed on the rear side of the base, a lifting mechanism disposed inside the mounting seat, and a stirring mechanism disposed at the top of the lifting mechanism.

[0008] Preferably, the extrusion mechanism includes a fixed frame, which is fixedly connected to the rear side of the base. An arc-shaped plate is fixedly connected to the top of the fixed frame, and multiple equally spaced extrusion triangular blocks are fixedly connected to the front side of the arc-shaped plate.

[0009] Preferably, the guide rod includes a connecting rod and a lever. The connecting rod is fixedly connected to the bottom of the vibrating plate, the limiting plate is fixedly connected to the connecting rod, the bottom end of the connecting rod is fixedly connected to a pin, the lever is rotatably connected to the pin, a torsion spring is sleeved on the pin, and the two ends of the torsion spring are fixedly connected to the connecting rod and the lever respectively. The bottom end of the connecting rod and the top end of the lever are set in a stepped shape that can be connected to each other.

[0010] Preferably, the electromagnetic heating mechanism includes a heat transfer conductor ring, which is fixedly connected to the outer wall of the ball mill jar. An electromagnetic coil is sleeved on the outside of the heat transfer conductor ring, and a cover is sleeved on the outside of the electromagnetic coil. The cover is fixedly connected to the ball mill jar, and an insulation plate is provided on the inner wall of the cover.

[0011] Preferably, the flipping mechanism includes a support, which is fixedly connected to the top of the base. A flipping motor is fixedly connected to one side of the support, and the output shaft of the flipping motor is fixedly connected to a rotating shaft, which is fixedly connected to the cover.

[0012] Preferably, the lifting mechanism includes a hydraulic cylinder, which is fixedly connected inside the mounting base.

[0014] The beneficial effects are as follows: After the material is ball-milled, the ball mill jar is rotated, and the ball mill jar drives the guide rod to make a circular motion. When the ball mill jar reaches a certain angle, the guide rod and the extrusion mechanism will extrude. As the ball mill jar rotates, the guide rod drives the vibrating plate to reciprocate under the action of the spring. The vibrating plate will collide with the inner wall of the ball mill jar, thereby causing the vibrating plate and the ball mill jar to vibrate, so that the material is discharged more thoroughly. There is no need to manually knock the ball mill jar, making it more convenient to use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-6 As shown, an electromagnetic heating and stirring ball mill includes a base 1, a mounting seat 101 and a tilting mechanism 2 fixed on the top of the base 1, a ball mill jar 3 disposed between the mounting seat 101 and the tilting mechanism 2, the tilting mechanism 2 being used to drive the ball mill jar 3 to tilt for unloading, an electromagnetic heating mechanism 4 disposed on the outer wall of the ball mill jar 3, a vibration mechanism 5 disposed at the bottom of the ball mill jar 3, the vibration mechanism 5 including a vibrating plate 501 disposed inside the ball mill jar 3, a guide rod 502 fixedly connected to the bottom of the vibrating plate 501, the guide rod 502 penetrating the bottom wall of the ball mill jar 3, the vibrating plate 501 being able to move along the axis of the ball mill jar 3 via the guide rod 502, a limiting plate 503 fixedly connected to the guide rod 502, a spring 504 fixedly connected between the top of the limiting plate 503 and the bottom of the ball mill jar 3, a pressing mechanism 6 for pressing the guide rod 502 disposed on the rear side of the base 1, a lifting mechanism 7 disposed inside the mounting seat 101, and a stirring mechanism 8 disposed at the top of the lifting mechanism 7.

[0028] The extrusion mechanism 6 includes a fixed frame 601, which is connected to the rear side of the base 1 by screws. An arc-shaped plate 602 is welded to the top of the fixed frame 601, and multiple equally spaced extrusion triangular blocks 603 are welded to the front side of the arc-shaped plate 602.

[0029] The guide rod 502 includes a connecting rod 5021 and a lever 5022. The connecting rod 5021 is fixedly connected to the bottom of the vibrating plate 501, and the limiting plate 503 is fixedly connected to the connecting rod 5021. A pin 5023 is fixedly connected to the bottom end of the connecting rod 5021, and the lever 5022 is rotatably connected to the pin 5023. A torsion spring 5024 is sleeved on the pin 5023, and both ends of the torsion spring 5024 are fixedly connected to the connecting rod 5021 and the lever 5022, respectively. The bottom end of the connecting rod 5021 and the top end of the lever 5022 are set in a stepped shape that can be mated together, so that the lever 5022 can only be mated relative to each other. When the connecting rod 5021 rotates in one direction, under the action of the torsion spring 5024, in its natural state, the lever 5022 and the connecting rod 5021 remain coaxial. During unloading, the top of the ball mill jar 3 flips forward, causing the opening of the ball mill jar 3 to tilt downward. During this process, the lever 5022 is squeezed by the squeezing triangular block 603, causing the vibrating plate 501 to move and the spring 504 to be compressed. When the lever 5022 disengages from the squeezing triangular block 603, the spring 504 rebounds, causing the vibrating plate 501 to impact the ball mill jar 3, thereby causing the vibrating plate 501 and the ball mill jar 3 to vibrate, making the unloading more thorough.

[0030] The electromagnetic heating mechanism 4 includes a heat transfer conductor ring 401, which is fixedly connected to the outer wall of the ball mill jar 3. An electromagnetic coil 402 is sleeved on the outside of the heat transfer conductor ring 401. When the electromagnetic coil 402 is energized, the heat transfer conductor ring 401 is heated, and the heat transfer conductor ring 401 heats the ball mill jar 3, thereby heating the material inside the ball mill jar 3. A cover 403 is sleeved on the outside of the electromagnetic coil 402, and the cover 403 is fixedly connected to the ball mill jar 3. An insulation plate 404 is provided on the inner wall of the cover 403 to reduce heat loss.

[0031] The flipping mechanism 2 includes a support 201, which is connected to the top of the base 1 by screws. A flipping motor 202 is connected to one side of the support 201 by screws. The output shaft of the flipping motor 202 is fixedly connected to a rotating shaft 203, which is fixedly connected to the cover 403.

[0032] The lifting mechanism 7 includes a hydraulic cylinder 701, which is connected to the inside of the mounting base 101 by screws. The output end of the hydraulic cylinder 701 is fixedly connected to a lifting plate 702, and multiple lifting rods 703 are fixedly connected to the top of the lifting plate 702. The lifting rods 703 extend from the top of the mounting base 101.

[0033] The stirring mechanism 8 includes a transmission body 801, which is fixedly connected to the top of the lifting rod 703. A stirring motor 802 is installed at the power input end of the transmission body 801, and a stirring shaft 803 is connected to the power output end of the transmission body 801. A cover plate 804 is rotatably connected to the stirring shaft 803.

[0034] Working principle: During use, the material to be ground and grinding balls are placed into the grinding jar 3. The hydraulic cylinder 701 drives the lifting rod 703 to move downward through the lifting plate 702. The lifting rod 703 drives the transmission body 801 to move downward, so that the stirring shaft 803 enters the grinding jar 3 and the cover plate 804 presses tightly against the top of the grinding jar 3. Then, the stirring motor 802 provides power to make the stirring shaft 803 rotate for ball grinding. After ball grinding is completed, the stirring shaft 803 rises, and then the tilting motor 202 drives the rotating shaft 203 to rotate, causing the grinding jar 3 to tilt. The top opening of the grinding jar 3 tilts forward and tilts downward. During this process, the guide rod 502 rotates with the grinding jar 3. When the lever 5022 abuts against the extrusion triangle block 603, the extrusion triangle block 603 extrudes the lever 5022, causing the grinding jar 3 to tilt downward. The lever 5022 drives the connecting rod 5021 to move, and the connecting rod 5021 drives the vibrating plate 501 to move. The spring 504 is compressed. When the lever 5022 disengages from the extrusion triangle block 603, the spring 504 rebounds and drives the connecting rod 5021 to move in the opposite direction. The connecting rod 5021 drives the vibrating plate 501 to move in the opposite direction, so that the vibrating plate 501 collides with the ball mill jar 3, thereby causing both the vibrating plate 501 and the ball mill jar 3 to vibrate, thus enabling the material to be discharged more thoroughly. After the material is discharged, the ball mill jar 3 rotates in the opposite direction to reset. At this time, the lever 5022 also begins to reset. Due to the obstruction of the extrusion triangle block 603, the lever 5022 will rotate relative to the connecting rod 5021, so that the ball mill jar 3 can be reset smoothly. After the reset is completed, it waits for the next ball milling.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
