Description

Technical Field

[0001] The invention belongs to the technical field of mica papermaking, in particular to an ore crushing device for processing mica sheets. Background Art

[0002] Mica paper is an electrical insulation product made from mica and has excellent insulation properties. In the early stages of mica paper manufacturing, the mined mica ore needs to be cleaned and crushed.

[0003] Before mica paper is formed, the mica needs to be made into mica slurry. The more widely used methods are calcined chemical pulping and hydraulic pulping. However, no matter which pulping method is used, the mica frame needs to be crushed into mica flakes. Only mica flakes of suitable size can be used for pulping. The commonly used mining crushing equipment can easily crush the mica ore into powder, resulting in the mica flakes being unable to maintain the shape of large blocks, and the crushed mica into powder can easily cause resource waste; on the other hand, the current mining crushing equipment is all aimed at crushing into fine particles. When crushing mica, there is not enough space to accommodate the mica flakes that have been broken into flakes, resulting in the suitable mica flakes also being crushed into powder. Therefore, it cannot meet the actual processing needs. Therefore, a special crushing equipment that is convenient for mica sheet processing is needed. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems and provide an ore crushing device for mica sheet processing, which can reduce the fine powdery mica particles, facilitate the formation of mica sheets, and facilitate the discharge of mica sheets.

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0040] As the instruction manual Figure 1-9 As shown in the figure, as a specific embodiment of the present invention, the specific structure of the present invention is: a mica sheet processing ore crushing device, comprising a first crushing member 10 and a second crushing member 11, the second crushing member 11 is symmetrically arranged on both sides of the first crushing member 10, and a crushing space 20 is formed between the second crushing member 11 and the first crushing member 10. During crushing, the second crushing member 11 performs a reciprocating impact motion relative to the first crushing member 10. Figure 1As shown, in the present application, the first crushing member 10 is provided in a cylindrical shape, the second crushing member 11 is provided in an arc-shaped plate-like structure, the outer side of the second crushing member 11 is connected to a first driving mechanism 14 for driving its reciprocating impact motion, in this embodiment, the first driving mechanism 14 includes a driving motor, the output shaft end of the motor is connected to a reducer, the output end of the reducer is connected to an eccentric wheel, the eccentric wheel is rotatably connected to a connecting rod connected to the second crushing member 11, the upper end of the second crushing member 11 is hingedly provided with a connecting rod, the connecting rod and the support plate 17 are hingedly provided, the support plate 17 is fixed on the support seat 18, and the support seat 18 is provided with an adjusting device for adjusting the position of the second crushing member 11 (similar to a jaw crusher), when the motor is started, it can drive the second crushing member 11 to reciprocate to impact and crush the mica ore;

[0041] A plurality of first crushing bars 101 and a second crushing bar 111 are respectively provided on one side of the crushing working surface of the first crushing member 10 and the second crushing member 11. The first crushing bars 101 and the second crushing bars 111 are vertically arranged to be staggered with each other. The end faces of the first crushing bars 101 and the second crushing bars 111 have the same shape. For details, please refer to the attached Figure 7 As shown, the first crushing bar 101 and the second crushing bar 111 are both crushing bars with sharp tips. When crushing, the sharp-pointed crushing bars impact the mica ore, which can reduce the force-bearing area of the mica ore, concentrate the force on the mica ore, reduce the generation of fine powder particles during crushing, and facilitate the formation of blocky mica flakes.

[0042] A discharge cavity 12 is provided between the first crushing bar 101 and the second crushing bar 111 to facilitate discharge. The discharge cavity 12 is specifically the spacing between the first crushing bar 101 and the second crushing bar 111, similar to the gap between the inner and outer threads during a threaded connection (here only as an example of the structure of the discharge cavity 12 for ease of understanding). After the mica is crushed, a storage space can be formed for the crushed mica to reduce the squeezing and crushing of the mica sheets, thereby facilitating the discharge of the mica sheets.

[0043] Please refer to the instruction manual Figure 1 、 3 As shown, the above embodiment is further optimized: in order to facilitate the cleaning of the second crushing member 11 after the crushing is completed, and to quickly discharge the mica ore between the first crushing member 10 and the second crushing member 11, in this embodiment, a plurality of cleaning members 112 are movably provided on one side of the working surface of the second crushing member 11, and the cleaning members 112 are located between the two second crushing bars 111. Figure 3 As shown, the cleaning member 112 is specifically embedded in the inner wall of the second crushing member 11, and is specifically in the shape of a strip having the same curvature as the second crushing member 11;

[0044] A push rod 113 is fixedly provided on the cleaning piece 112, and the push rod 113 passes through the second crushing piece 11, and an elastic piece 114 is provided between the second crushing piece 11. The elastic piece 114 is specifically a spring. A top plate 13 is provided on the outside of the second crushing piece 11, which can contact the push rod 113 to push the cleaning piece 112 inward.

[0045] A second driving mechanism 15 is connected below the first driving mechanism 14. The second driving mechanism 15 is a linear driving mechanism, specifically including a movable bottom plate fixed to the first driving mechanism 14, a screw rod connected to the movable bottom plate, and a driving motor connected to the screw rod, or directly controlled by a hydraulic cylinder. When the second driving mechanism 15 drives the first driving mechanism 14 and the second crushing member 11 away from the first crushing member 10, it can drive the distance between the second crushing member 11 and the first crushing member 10 to expand, so that all the crushed mica between the first crushing member 10 and the second crushing member 11 falls down, and drives the push rod 113 to contact with the top plate 13, and pushes out the cleaning member 112, so that the mica ore stuck in the gap between the second crushing bars 111 can be cleaned.

[0046] Please refer to the instruction manual Figure 1 、 2 , 5, 6, 7, and 8, further optimized on the basis of the above embodiment: in order to accelerate the discharge speed of the crushed mica sheets, a support cylinder 16 is coaxially arranged inside the first crushing member 10, and the support cylinder 16 is mainly used to support the first crushing member 10 to improve the rigidity of the first crushing member 10 during crushing. The support cylinder 16 is internally connected to the air source, which can be referred to in the attached figure. Figure 7 As shown, the air source connected to the support cylinder 16 is connected to the air source outside through the rotating shaft of the support cylinder 16; the support cylinder 16 is fixed on the support plate 17, and the first crushing member 10 is rotated with the support cylinder 16 and the support plate 17. The first crushing member 10 is connected to the drive assembly (see Figure 2 ), the driving assembly connected to the first crushing member 10 is a driving motor provided on the rear side of the support plate 17, the motor is connected to a multi-stage reducer, and a chain drive is adopted between the output shaft of the reducer and the rotating shaft of the first crushing member 10;

[0047] The side of the support tube 16 is provided with a plurality of notches 161 which penetrate inside and outside (see the attached Figure 5 、 7), a plurality of exhaust holes 102 are provided on the surface of the first crushing member 10. When crushing the mica ore, the motor connected to the first crushing member 10 is started. After the motor slows down, it drives the first crushing member 10 to rotate. During the rotation, the first crushing bar 101 can be constantly changed to enter the crushing position to reduce the wear on the first crushing bar 101. When the exhaust hole 102 rotates to communicate with the slot 161, the mica sheet is blown out. The mica sheet is relatively light, and the discharge of the mica sheet can be accelerated during the blowing process, thereby reducing the damage to the mica sheet.

[0048] The notches 161 are symmetrically arranged on both sides of the support cylinder 16, and the exhaust holes 102 are symmetrically arranged on both sides of the first crushing member 10, and the exhaust holes 102 are tilted toward the discharge side of the first crushing member 10 and the second crushing member 11. Figure 1 , with attached Figure 1 Taking the front, back, left and right directions as an example, the notches 161 are symmetrically arranged on both sides of the central axis of the notch 161 and close to the crushing position. During the crushing process, only one of the second crushing members 11 on the left and right sides is performing the crushing work, while the other is pulled apart by the second driving mechanism 15 for discharging, and only one side of the exhaust hole 102 is kept connected to the notch 161, and the connected exhaust hole 102 is located on the side that is performing the crushing work.

[0049] Specifically, with Figure 1 and 8 Taking the front, back, left and right directions in the figure as an example, when the motor connected to the first crushing member 10 is started to drive the first crushing member 10 to rotate to the left, the second driving mechanism 15 connected to the second crushing member 11 on the right can be controlled to drive the second crushing member 11 on the right to be pulled to the right, so as to expand the gap between the first crushing member 10 and the second crushing member 11 on the right, so as to facilitate the rapid discharge of the mica ore, and the cleaning member 112 is pushed out to clean the interval between the second crushing bars 111 to prevent the mica ore from being stuck on the second crushing member 11. Whether to discharge the material is selected according to the actual working conditions. When the material is not discharged, the crushing work is not performed; the first crushing member 10 rotates to the left (that is, the second crushing member 11 on the right is not discharged). Figure 8 When the first crushing member 10 rotates counterclockwise), the exhaust hole 102 on the left and the slot 161 on the left can be connected to each other. At this time, the air blown into the support tube 16 can be blown out from the slot 161 and the exhaust hole 102 to accelerate the crushed mica sheets to be blown out to the side of the discharge port. The direction of rotation of the first crushing member 10 can drive the ore to move into the crushing member working position. During the rotation process, it can play a role in moving the crushed mica sheets and move the mica sheets to the discharge side. The rotation of the first crushing member 10 can keep the wear on its surface uniform.

[0050] Similarly, when the second crushing member 11 on the right is performing the crushing work, the motor connected to the first crushing member 10 can be controlled to rotate in the opposite direction to drive the first crushing member 10 to rotate to the right, and the exhaust hole 102 and the slot 161 on the right are connected to each other to blow the crushed mica sheets out to the discharge port.

[0051] Please refer to the instruction manual Figure 1 、 2 , 4, and 9, further optimized on the basis of the above embodiment: a support base 18 is fixedly provided on the outer side of the support plate 17, and a feed hopper 19 is movably provided on the top of the support base 18;

[0052] The feed hopper 19 is connected to the driving assembly connected to the first crushing element 10 by power. A platform 23 is fixedly provided on the top of the support base 18. The feed hopper 19 is slidably provided on the platform 23. A transmission device connected to the driving assembly by power is provided on the platform 23.

[0053] The transmission device includes a gear 24 rotatably arranged on one side of the platform 23, and the feed hopper 19 is provided with a rack 25 that meshes with the gear 24. The platform 23 is also provided with elastic plugs 26 on both sides of the gear 24. The elastic plugs 26 can push the rack 25 and the gear 24 to keep in contact with each other. Specifically, the length of the rack 25 is slightly shorter than the sliding distance of the feed hopper 19. When the feed hopper 19 moves to the extreme position, it drives the rack 25 to press against the elastic plugs 26 and compress. At this time, the rack 25 and the gear 24 are disengaged from each other, and the feed hopper 19 will not slide. When the gear 24 stops rotating, the elastic plugs 26 will cause the rack 25 and the gear 24 to contact each other due to the elastic pushing effect, thereby keeping the gear 24 and the rack 25 in a meshed state. When the gear 24 rotates in the opposite direction, it will drive the rack 25 and the feed hopper 19 to move in the opposite direction, thereby realizing the movement of the feed hopper 19 in different directions. Figure 9 As shown;

[0054] A sprocket connected to the driving assembly connected to the first crushing member 10 is also provided on the rotating shaft of the gear 24. Specifically, a sprocket transmission is adopted between the gear 24 and the output shaft of the multi-stage reducer connected to the first crushing member 10, so that after the motor connected to the first crushing member 10 is started, the feed hopper 19 can be driven to move and the first crushing member 10 can be rotated synchronously.

[0055] The raw materials to be crushed are fed into the crushing space 20 through the feed hopper 19. A partition block 21 located in the crushing space 20 is fixedly provided on the support plate 17. The partition block 21 divides the crushing space 20 into two parts. By controlling the feed hopper 19 to move at different positions, the feed hopper 19 can be moved to the corresponding position for feeding when the second crushing part 11 and the first crushing part 10 at different positions are crushing.

[0056] A combing block 22 is hingedly provided on the support plate 17 , and the combing block 22 contacts the first crushing member 10 to comb out the gaps between the first crushing bars 101 , thereby preventing the mica ore from being stuck between the first crushing bars 101 .

[0057] The specific working principle of the present invention is as follows: the mica ore to be processed is placed in the feed hopper 19, and the first driving mechanism 14 on one side is started. The first driving mechanism 14 drives the second crushing member 11 to reciprocate and impact. The motor connected to the first crushing member 10 is controlled to start. The motor drives the feed hopper 19 to move toward the side of the working second crushing member 11, and drives the first crushing member 10 to rotate toward the side of the working second crushing member 11. The feed hopper 19 pours the mica ore into the crushing space 20 for crushing. In the process of rotation of the first crushing member 10, the exhaust hole 102 and the notch 161 are gradually connected, and the crushed mica is blown out to the side of the discharge port. In the process of rotation, the first crushing member 10 will also synchronously drive part of the mica sheets to move toward the side of the discharge port, which ensures the uniformity of wear on the first crushing member 10 and can also play a toggling role in the timely discharge of the mica sheets.

[0058] When the exhaust hole 102 and the notch 161 are not connected to each other, the first driving mechanism 14 is controlled to stop working and the second driving mechanism 15 is controlled to start working to pull the second crushing member 11 and the first crushing member 10 apart. In the process of pulling the second crushing member 11 apart, the top plate 13 and the push rod 113 press against each other, so that the cleaning member 112 can be pushed out from between the second crushing bars 111 to push out and clean the mica ore stuck between the second crushing bars 111. At this time, the motor connected to the first crushing member 10 can be controlled in the reverse direction, and the motor drives the feed hopper 19 to move to the other side. The first crushing member 10 rotates in the opposite direction, and the mica ore falls between the first crushing member 10 and the second crushing member 11 on the other side for crushing. When the exhaust hole 102 and the notch 161 on this side are connected to each other, the crushed mica flakes can continue to be blown out to the side of the discharge port. In this way, the two sides are cyclically switched to reduce the wear of the first crushing member 10 and the second crushing member 11 on both sides during work, accelerate the discharge of the crushed mica flakes, and reduce the generation of mica powder particles.
