Description

Technical Field

[0001] The utility model relates to a ball mill, in particular to a refractory slurry mixing ball mill. Background Art

[0002] At present, a Chinese patent with authorization announcement number CN203002437U discloses a ball mill, which includes a frame divided into at least two layers, a motor is provided on the frame, and the motor drives a main rotating shaft through a belt, and a secondary rotating shaft parallel to the main rotating shaft is also provided. The main rotating shaft and the secondary rotating shaft are both provided with rotating shaft sleeves.

[0003] This type of ball mill, by having multiple main and auxiliary shafts, can accommodate multiple ball mills, enabling simultaneous grinding of small amounts and multiple materials. However, the surfaces of the ball mills and the shaft sleeves can wear, and during rotation, the ball mills can easily move along the length of the main shaft and fall between the main and auxiliary shafts. Utility Model Content

[0004] In view of this, the purpose of the present utility model is to provide a refractory slurry mixing ball mill, so as to achieve the purpose of making the ball mill jar less likely to move.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a refractory slurry mixing ball mill, including a ball mill, a frame, a main shaft, and a secondary shaft, the main shaft and the secondary shaft are both rotatably connected to the frame, the axis of the main shaft and the axis of the secondary shaft are arranged in parallel, and a accommodating cavity for placing the ball mill is formed between the main shaft and the secondary shaft, a fixed plate is fixedly connected to the frame, a support rod is rotatably connected to the fixed plate, the end of the ball mill is fixedly connected to a fixing ring, a notch is provided on the fixing ring, the support rod is rotatably connected to a connecting ring, a clamping plate is connected to the connecting ring, the clamping plate passes through the notch and contacts the inner wall of the fixing ring.

[0006] To implement the above technical solution, the ball mill is placed in the accommodating cavity, and the clamping plate is passed through the gap. The clamping plate is located inside the fixed ring. The clamping plate and the inner wall of the fixed ring interfere with each other, so that the ball mill is not easily moved along the axial direction of the main shaft. When the main shaft rotates, the friction force causes the ball mill to drive the secondary shaft to rotate synchronously. At the same time, the ball mill drives the clamping plate, the connecting ring, and the support rod to rotate.

[0007] As a preferred solution of the present invention, there are multiple clamping plates, and the multiple clamping plates are evenly arranged along the axis of the connecting ring. The number of the notches is equal to the number of the clamping plates, and the multiple notches are evenly arranged along the axis of the ball mill jar. The support rod is coaxially arranged with the ball mill jar.

[0008] To implement the above technical solution, multiple clamping plates are provided to make the ball mill jar rotate more smoothly.

[0009] As a preferred solution of the present invention, the clamping plate includes a fixed part and a clamping part, the fixed part is fixedly connected to the connecting ring, the clamping part is slidably connected to the fixed part, a sliding groove is provided on the fixed part, a slider is fixed on the clamping part, the slider is slidably connected in the sliding groove and is connected to the sliding groove through an anti-slip component, and an elastic part is connected between the inner wall of the sliding groove and the slider.

[0010] To implement the above technical solution, the slider is placed in the slide groove, and the anti-slip component is used to prevent the slider from easily falling out of the slide groove. The elastic force of the elastic member is used to apply a force to the slider, so that the slider moves along the length direction of the slide groove, so that the clamping part is pressed against the inner wall of the fixed ring. The elastic force of the elastic member makes it difficult for the clamping part to slide relative to the fixed ring, thereby reducing wear. At the same time, it can adapt to fixed rings of different sizes, thereby improving practicality.

[0011] As a preferred solution of the present invention, the anti-slip assembly includes an installation recessed hole, a spring piece, an anti-slip block, and a guide slope. The installation recessed hole is opened on the side wall of the slider, and the anti-slip block is slidably connected to the installation recessed hole. The two ends of the spring piece are respectively connected to the inner wall of the installation recessed hole and the anti-slip block. The guide slope is opened on the anti-slip block and is used to interfere with the edge of the slide groove. The anti-slip block is slidably connected to the slide groove along with the slider.

[0012] To implement the above technical solution, the slider is moved toward the slide groove so that the guiding inclined surface contacts the edge of the slide groove, and the anti-slip block is pressed into the mounting recessed hole. After the slider is placed in the slide groove, the elastic force of the spring piece causes a part of the anti-slip block to extend from the mounting recessed hole and be placed in the slide groove, thereby making it difficult for the slider to fall out of the slide groove.

[0013] As a preferred solution of the present invention, an adjustment hole is provided on the support rod, an adjustment rod is threadedly connected to the adjustment hole, the adjustment rod is connected to a baffle for contacting the end of the ball mill, and a locking sleeve is threadedly connected to the adjustment rod for tightening against the end of the support rod.

[0014] To implement the above technical solution, the adjusting rod is rotated so that the baffle contacts the end of the ball mill jar. Through the pressing force, the clamping plate is moved away from the fixing ring, so that the force between the clamping plate and the fixing ring is greater, thereby further improving the connection stability between the clamping plate and the fixing ring. The locking sleeve is rotated and pressed against the end of the support rod to position the adjusting rod.

[0015] As a preferred solution of the present invention, the frame is connected to a sub-frame, the sub-frame is rotatably connected to a linkage rod and an auxiliary rod, the axis of the linkage rod is parallel to the axis of the auxiliary rod, and the linkage rod is connected to the main shaft through a universal joint.

[0016] To implement the above technical solution, the main shaft rotates, and the linkage rod rotates through the universal joint, so that the ball mill located between the linkage rod and the auxiliary rod can also rotate synchronously, so as to realize the rotation of multiple ball mills, greatly improving practicality.

[0017] As a preferred solution of the present invention, friction sleeves are connected to the outer walls of the main shaft, secondary shaft, linkage rod and auxiliary rod.

[0018] The above technical solution is implemented to improve the friction between the ball mill and the ball mill, making the ball mill rotate more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0024] A refractory slurry mixing ball mill comprises a ball mill 1, a frame 2, a main shaft 21, and a secondary shaft 22. Both the main shaft 21 and the secondary shaft 22 are rotatably connected to the frame 2, and the main shaft 21 is driven by a motor (not shown). The axes of the main shaft 21 and the secondary shaft 22 are parallel to each other; a cavity for accommodating the ball mill 1 is formed between the main shaft 21 and the secondary shaft 22.

[0025] A sub-frame 3 is fixedly connected to one side of the frame 2. A linkage rod 31 and an auxiliary rod 32 are rotatably connected to the sub-frame 3. The axis of the linkage rod 31 is parallel to the axis of the auxiliary rod 32. The linkage rod 31 is connected to the main shaft 21 via a universal joint 33. A friction sleeve 34, made of rubber, is fixedly attached to the outer walls of the main shaft 21, the auxiliary shaft 22, the linkage rod 31, and the auxiliary rod 32. The outer diameters of the main shaft 21, the auxiliary shaft 22, the linkage rod 31, and the auxiliary rod 32 are all equal.

[0026] Place one ball mill 1 in the accommodating chamber, and another ball mill 1 between the linkage rod 31 and the auxiliary rod 32. When the motor starts, the main shaft 21 rotates, causing the ball mill 1 and the secondary shaft 22 to rotate synchronously through friction. Simultaneously, the coupling drives the linkage rod 31 to rotate synchronously. As the linkage rod 31 rotates, friction also causes the ball mill 1 and the auxiliary rod 32 to rotate synchronously, enabling multiple ball mills 1 to rotate simultaneously.

[0027] A fixed plate 4 is fixedly connected to the frame 2, and a support rod 41 is rotatably connected to the fixed plate 4. The axis of the support rod 41 is parallel to the axis of the main shaft 21. A connecting ring 42 is rotatably connected to the support rod 41 through a bearing, and a clamping plate 5 is fixedly connected to the outer wall of the connecting ring 42. Three clamping plates 5 are evenly distributed along the axis of the connecting ring 42.

[0028] Furthermore, a fixing ring 6 is fixedly connected to the end of the ball mill 1. The fixing ring 6 has an L-shaped cross section and is provided with three notches 61 evenly distributed along the axis of the ball mill 1. The clamping plate 5 passes through the notches 61 and contacts the inner wall of the fixing ring 6.

[0029] The clamping plate 5 includes a fixing portion 51 and a clamping portion 52. The fixing portion 51 is fixedly connected to the connecting ring 42, and the clamping portion 52 is slidably connected to the fixing portion 51, and the clamping portion 52 is used to press against the fixing ring 6. A slide groove 53 with a T-shaped cross section is provided on the fixing portion 51, and the length direction of the slide groove 53 is parallel to the length direction of the fixing portion 51. A slider 54 is fixed on the clamping portion 52, and the slider 54 is slidably connected in the slide groove 53 and is connected to the slide groove 53 through an anti-slip component 7. An elastic member 55 is connected between the inner wall of the slide groove 53 and the slider 54. The elastic member 55 is a spring. Through the elastic force of the elastic member 55, a force is applied to the slider 54, so that the clamping portion 52 continues to have a tendency to move toward the fixing ring 6.

[0030] The anti-slip assembly 7 includes a mounting recess 71, a spring 72, an anti-slip block 73, and a guide ramp 74. The mounting recess 71 is formed on the sidewall of the slider 54, and the anti-slip block 73 is slidably connected to the mounting recess 71. The spring 72 is also a spring, connecting its ends to the inner wall of the mounting recess 71 and the anti-slip block 73, respectively. The guide ramp 74 is formed on the anti-slip block 73 and is configured to contact the edge of the chute 53. The anti-slip block 73 is slidably connected to the chute 53 along with the slider 54.

[0031] The slider 54 is moved toward the chute 53 so that the guide slope 74 contacts the edge of the chute 53, and the anti-slip block 73 is pressed into the mounting recess 71. After the slider 54 is placed in the chute 53, the elastic force of the spring 72 causes a portion of the anti-slip block 73 to extend from the mounting recess 71 and be placed in the chute 53, thereby preventing the slider 54 from being easily removed from the chute 53.

[0032] An adjustment hole 8 is defined in the support rod 41 and is coaxial with the support rod 41. An adjustment rod 81 is threadedly connected to the adjustment hole 8. A baffle 82 is fixedly connected to the end of the adjustment rod 81, which is away from the support rod 41, and is designed to abut against the end of the ball mill jar 1. A locking sleeve 83 is threadedly connected to the adjustment rod 81 and is designed to abut against the end of the support rod 41.

[0033] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
