Abstract

This invention discloses a raw material crushing device for calcium carbonate powder production based on an energy-saving electric motor, relating to the field of calcium carbonate powder production technology. The invention includes a crushing box, with a main shaft rotatably connected to the inner right surface of the crushing box. A crushing roller is fixedly connected to the left end of the main shaft. A mounting frame is fixedly connected to the right side of the crushing box, and a sleeve shaft is fixedly connected to the left side of the crushing roller. Linear motors are fixedly connected to both sides of the crushing box, and a moving seat is fixedly connected to the moving end of each linear motor. The invention utilizes a device where the impacted inclined block vibrates upon impact, transmitting the force of the vibration to the crushing roller. The crushing roller, under pressure, twists and vibrates along its axis. Because the eccentric impact blocks inside the front and rear crushing rollers are set at different angles, the twisting directions of the two crushing rollers are different, causing the two crushing rollers to vibrate alternately. This grinds or shakes off raw materials stuck between the crushing rollers, thus preventing the device from jamming or being damaged.

[0002] Calcium carbonate powder is a white powder made from natural calcium carbonate minerals such as calcite, marble, and limestone through crushing and grinding. As a common inorganic filler, it is widely used in industries such as plastics, rubber, papermaking, coatings, building materials, and feed, and can whiten, strengthen, and reduce costs.

A casing is fixedly connected to the front and rear sides of the crushing box, and locking rods are slidably connected to the inner surfaces of the front and rear ends of the casing. A pull shaft is fixedly connected to the end of the locking rod away from the crushing roller.

[0011] In the above technical solution, the descaling device further includes: Inner ring, which is fixedly connected to the circumferential surface of the locking rod; A U-shaped connecting plate is fixedly connected to the front end of the push rod, and a sliding rod is fixedly connected to the rear side of the U-shaped connecting plate; A friction base, which is fixedly connected to the circumferential surface of the slide rod; The guide rail is fixedly connected to the front and rear sides of the inner wall of the crushing chamber.

[0012] In the above technical solution, a torsion spring is further provided at the hinge of the rotary plate and the crushing box. The locking rod slides through the crushing box from both the front and rear sides and enters the crushing box. The locking rod is engaged with the inner surface of the rotary plate. The inner ring is slidably connected to the inner surface of the casing. A spring is provided between the side of the inner ring away from the crushing box and the side of the inner wall of the casing away from the crushing box. The sliding rod slides through the front side of the crushing box and enters the crushing box. A brush is provided on the upper surface of the friction base.

[0016] The beneficial effects of this invention are: 1. The impacted inclined block vibrates upon impact, transmitting the force to the crushing roller. The crushing roller then twists and vibrates along its axis. Due to the different angles of the eccentric impact blocks inside the front and rear crushing rollers, the two crushing rollers twist in different directions, causing them to vibrate alternately. This grinds or shakes off the material stuck between the crushing rollers, preventing the device from jamming and being damaged, and improving the material crushing efficiency. The constraint force of the rotating shaft on the eccentric impact block is greater than the weight of the eccentric impact block itself, thus enabling it to rotate synchronously and impact the impacted inclined block. Therefore, the L-shaped lever can precisely control the rotating shaft and the eccentric impact block to impact the impacted inclined block at any time, improving the emergency response capability of the device.

[0017] 2. The scraper claws pop up and insert between the crushing roller teeth to scrape off the "material pad" adhering to the roller surface, preventing the crushing roller from being affected by the "material pad" during long-term use and thus reducing the crushing effect. The locking rod is inserted between the crushing box and the rotating plate to lock the rotating plate, preventing the scraper claws from contacting the crushing roller surface for a long time. The friction base slides back and forth on the guide rail, and the brush above the friction base contacts the crushing roller surface and sweeps away some of the calcium carbonate powder, thereby improving the cleaning effect of the crushing roller.

[0018] 3. Push the pusher plate towards the center of the device. The pusher plate slides on the slide block through the slider and pushes the excess material to the other side, making the material distribution more uniform and avoiding serious material accumulation on one side. This improves the crushing efficiency of the material. When the slide plate moves backward, it drives the push shaft to move backward. The guide slide pulls the guide plate and pusher plate to reset, which facilitates multi-batch processing. This allows the device to continuously flatten the material, improves the uniformity of material distribution during long-term operation, reduces roller idling, and improves the overall crushing efficiency.

[0021] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figure 1-9As shown, one embodiment of the present invention provides: a raw material crushing device for calcium carbonate powder production based on an energy-saving electric motor, comprising a crushing box 1, a main shaft 4 rotatably connected to the inner right side of the crushing box 1, a crushing roller 2 fixedly connected to the left end of the main shaft 4, a mounting frame 3 fixedly connected to the right side of the crushing box 1, a sleeve shaft 5 fixedly connected to the left side of the crushing roller 2, linear motors 6 fixedly connected to both sides of the crushing box 1, a moving seat 7 fixedly connected to the moving end of the linear motor 6, and a descaling device 8 disposed inside the crushing box 1 for removing scale buildup on the surface of the crushing roller 2. The "material pad" is removed. The polymerization device 9 is set above the crushing box 1. The polymerization device 9 is used to flatten the calcium carbonate raw material piled on one side. After being impacted, the impacted inclined block 12 vibrates and transmits the vibration force to the crushing roller 2. After being subjected to force, the crushing roller 2 twists and vibrates along the axis of the crushing roller 2. Because the eccentric impact blocks 11 inside the front and rear crushing rollers 2 are set at different angles, the twisting directions of the front and rear crushing rollers 2 are different, which causes the two crushing rollers 2 to vibrate alternately, so that the raw material stuck in the middle of the crushing rollers 2 is ground or shaken off, thereby avoiding the device from jamming and being damaged. To improve raw material crushing efficiency, the crushing box 1 includes a rotating shaft 10, which is rotatably connected to the inner surface of the sleeve shaft 5. An eccentric impact block 11 is hinged to the circumferential surface of the rotating shaft 10. An impact-bearing inclined block 12 is fixedly connected to the inner wall of the crushing roller 2. The crushing box 1 also includes a deflector plate 13, which is fixedly connected to the upper surface of the left end of the rotating shaft 10. An L-shaped locking rod 14 is fixedly connected to the upper surface of the moving seat 7. A connecting rod 15 is fixedly connected to the top side surface of the L-shaped locking rod 14. A push rod 16 is fixedly connected to the front side of the moving seat 7. The two sides of the crushing roller 2 and the two sides of the inner wall of the crushing box 1 abut against each other. The sleeve shaft 5 and The inner surface of the left side of the crushing box 1 is rotatably connected, the right end of the rotating shaft 10 is rotatably connected to the right side of the inner wall of the crushing roller 2, the L-shaped clamp 14 and the front and rear sides of the lever 13 abut against each other, the right end of the main shaft 4 is equipped with a motor, and the motor is fixedly installed above the mounting frame 3. The constraint force of the rotating shaft 10 on the eccentric impact block 11 is greater than the weight of the eccentric impact block 11 itself, so that it can drive it to rotate synchronously and impact the impacted inclined block 12. Thus, no matter when, the L-shaped clamp 14 can accurately control the rotating shaft 10 and the eccentric impact block 11 to impact the impacted inclined block 12, improving the emergency response effect of the device.

[0023] Working principle: Raw materials are poured into the crushing box 1, the motor is started, and the motor drives the main shaft 4 to rotate. The main shaft 4 drives the two crushing rollers 2 to rotate relative to each other. When the raw materials fall between the two crushing rollers 2, they are crushed into small particles by the roller teeth and then discharged through the bottom of the crushing box 1 for subsequent processing. When the crushing rollers 2 rotate, their left ends rotate on the left side of the crushing box 1 through the sleeve shaft 5. When a large piece of raw material gets stuck between the two crushing rollers 2, causing the crushing rollers 2 to jam, the crushing rollers 2 are stopped, and the linear motor 6 is started. The linear motor 6 drives... The movable seat 7 moves forward, driving the L-shaped clamp 14 and connecting rod 15 to move forward. When the L-shaped clamp 14 moves forward, it pushes the lever 13 to rotate around the axis of the sleeve shaft 5. The lever 13 then drives the rotating shaft 10 to rotate within the sleeve shaft 5 and the crushing roller 2. The rotating shaft 10 drives the eccentric impact block 11 to rotate around a certain angle and impact the impacted inclined block 12. The impacted inclined block 12 vibrates after being impacted and transmits the force of the vibration to the crushing roller 2. After being subjected to force, the crushing roller 2 torsional vibrations along the axis of the crushing roller 2. And because the two crushing rollers are subjected to force, the crushing roller 2 torsional vibrations are transmitted to the crushing roller 2. The eccentric impact blocks 11 inside roller 2 are set at different angles, causing the front and rear crushing rollers 2 to twist in different directions. This results in the two crushing rollers 2 vibrating alternately, which grinds or shakes off the material stuck between the crushing rollers 2, thus preventing the device from jamming and being damaged, and also improving the material crushing efficiency. During the rotation of the crushing roller 2, the baffle plate 13 is held stationary between the L-shaped clamping rods 14, while the crushing roller 2 drives the impacted inclined block 12 to rotate circumferentially. When the impacted inclined block 12 rotates circumferentially, the thrust generated by it is greater than that of the impacted inclined block 12. The constraint force of the rotating shaft 10 on the eccentric impact block 11 causes the eccentric impact block 11 to rotate on the rotating shaft 10, keeping the rotating shaft 10 stationary. When the eccentric impact block 11 and the impacted inclined block 12 stop rotating, the constraint force of the rotating shaft 10 on the eccentric impact block 11 is greater than the weight of the eccentric impact block 11 itself, thus enabling it to rotate synchronously and impact the impacted inclined block 12. Therefore, the L-shaped lever 14 can accurately control the rotating shaft 10 and the eccentric impact block 11 to impact the impacted inclined block 12 at any time, improving the emergency response effect of the device.

[0024] like Figure 1-9As shown, the second embodiment of the present invention provides: a descaling device 8 includes a rotary plate 81, which is hinged to the front and rear sides of the inner wall of the crushing box 1. A scraping claw 82 is fixedly connected to the side of the rotary plate 81 near the crushing roller 2. A housing 85 is fixedly connected to the front and rear sides of the crushing box 1. A locking rod 83 is slidably connected to the inner surfaces of the front and rear ends of the housing 85. A pull shaft 84 is fixedly connected to the end of the locking rod 83 away from the crushing roller 2. The scraping claw 82 pops up and inserts between the roller teeth of the crushing roller 2 to scrape off the "material pad" adhering to the roller surface, so as to avoid the crushing roller 2 from being affected by the "material pad" during long-term use, which would lead to a decrease in crushing effect. The locking rod 83 is inserted between the crushing box 1 and the rotary plate 81 to lock the rotary plate 81, so as to prevent the scraping claw 82 from contacting the roller surface of the crushing roller 2 for a long time. The descaling device 8 also includes an inner ring 86, which is fixedly connected to the circumferential surface of the locking rod 83. A U-shaped connecting plate 87 is fixedly connected to the front end of the push rod 16. A slide rod 88 is fixedly connected to the rear side of the crushing box 1. A friction base 89 is fixedly connected to the circumferential surface of the slide rod 88. A guide rail 810 is fixedly connected to the front and rear sides of the inner wall of the crushing box 1. A torsion spring is provided at the hinge of the rotary plate 81 and the crushing box 1. A locking rod 83 slides through the front and rear sides of the crushing box 1 and enters the interior of the crushing box 1. The locking rod 83 is engaged with the inner surface of the rotary plate 81. The inner ring 86 is slidably connected to the inner surface of the casing 85. A spring is provided between the side of the inner ring 86 away from the crushing box 1 and the side of the inner wall of the casing 85 away from the crushing box 1. The slide rod 88 slides through the front side of the crushing box 1 and enters the interior of the crushing box 1. A brush is provided on the upper surface of the friction base 89. The friction base 89 is slidably connected to the inner surface of the guide rail 810 through a sliding block. The friction base 89 slides back and forth on the guide rail 810. The brush above the friction base 89 contacts the roller surface of the crushing roller 2 and sweeps away some calcium carbonate powder, thereby improving the cleaning effect on the crushing roller 2.

[0025] Working Principle: Calcium carbonate raw materials tend to adhere to the surface of crushing roller 2 during crushing, forming a "material pad" that reduces subsequent crushing efficiency and causes uneven wear on the roller surface. During the crushing process, when a "material pad" forms on the surface of crushing roller 2, the pull shaft 84 is pulled. The pull shaft 84 drives the locking rod 83 to slide away from the crushing box 1, thereby unlocking the rotating plate 81. After unlocking, the rotating plate 81 rotates upward under the influence of the torsion spring, causing the scraping claw 82 to spring up and insert between the roller teeth of crushing roller 2 to scrape off the "material pad" adhering to the roller surface. This prevents the crushing roller 2 from being affected by the "material pad" during long-term use, thus reducing the crushing efficiency. After cleaning crushing roller 2, the pull shaft 84 is pulled first, then the rotating plate 81 is lowered, and then the pull shaft 84 is released. At this time, the inner ring 86 slides within the housing 85 under the influence of the spring's elastic reset action. The inner ring 86 moves closer to the crushing box 1, and during this process, it drives the locking rod 83 to insert between the crushing box 1 and the rotating plate 81, thereby locking the rotating plate 81 and preventing the scraping claw 82 from contacting the crushing roller 2 surface for a long time. When the crushing roller 2 stops rotating, the linear motor 6 is started. The linear motor 6 drives the moving seat 7 to move back and forth, the moving seat 7 drives the push rod 16 to move back and forth, the push rod 16 drives the U-shaped connecting plate 87 to move back and forth, the U-shaped connecting plate 87 drives the sliding rod 88 to slide back and forth at the bottom of the crushing box 1, and the crushing box 1 then drives the friction base 89 to slide back and forth on the guide rail 810. When the friction base 89 slides back and forth, the brush set above it contacts the crushing roller 2 surface and removes some of the calcium carbonate powder, improving the cleaning effect on the crushing roller 2.

[0026] like Figure 1-9 As shown, the third embodiment of the present invention provides: the polymerization device 9 includes a slide 91, which is fixedly connected to the upper surface of the crushing box 1. A slider 92 is slidably connected to the surface of the slide 91. A pusher plate 93 is fixedly connected to the upper surface of the slider 92. Pushing the pusher plate 93 towards the center of the device allows the pusher plate 93 to slide on the slide 91 via the slider 92 and push excess raw material to the other side, making the raw material distribution more uniform, avoiding severe accumulation on one side, and improving the crushing efficiency of the raw material. The polymerization device 9 also includes a guide plate 94, which is fixedly connected to the side surface of the pusher plate 93. A guide groove 95 is opened on the inner side of the guide plate 94. An L-shaped connecting plate 96 is fixedly connected to... A sliding plate 97 is fixedly connected to the top side surface of the U-shaped connecting plate 87 and the top rear side surface of the L-shaped connecting plate 96. A push shaft 98 is fixedly connected to the upper surface of the sliding plate 97. A hook frame 99 is fixedly connected to the left and right sides of the crushing box 1. The push shaft 98 and the inner surface of the guide groove 95 are slidably connected. The sliding plate 97 and the inner upper surface of the hook frame 99 are slidably connected. The sliding plate 97 abuts against the side surface of the crushing box 1. When the sliding plate 97 moves backward, it drives the push shaft 98 to move backward. The guide groove 95 pulls the guide plate 94 and the push plate 93 to reset, which facilitates multi-batch processing, allows the device to continuously flatten the raw materials, improves the uniformity of raw material distribution during long-term operation, reduces roller idling, and improves the overall crushing efficiency.

[0027] Working principle: When raw materials accumulate on one side of the crushing box 1, it can easily cause some roller surfaces to idle, reducing the crushing capacity per unit time. At this time, the pusher plate 93 on one side is pushed towards the center of the device. The pusher plate 93 slides on the slide block 91 via the slider 92 and pushes the excess raw materials to the other side, making the raw materials more evenly distributed and avoiding severe accumulation on one side, thus improving the crushing efficiency of the raw materials. The U-shaped connecting plate 87 is controlled to move back and forth, which drives the L-shaped connecting plate 96 to move back and forth. The L-shaped connecting plate 96 drives the sliding plate 97 to slide back and forth on the hook frame 99. When the sliding plate 97 moves forward, it drives the L-shaped connecting plate 96 to move back and forth. The push shaft 98 moves forward, and as it moves forward, it pushes the guide plate 94 toward the center of the device through the guide groove 95. The guide plate 94 then drives the push plate 93 to approach the center of the device and pushes the excess material to the other side. When the slide plate 97 moves backward, it drives the push shaft 98 to move backward. The push shaft 98 then pulls the guide plate 94 and the push plate 93 away from the center of the device through the guide groove 95, completing the reset. This facilitates multiple batch processing, allowing the device to continuously flatten the material, improving the uniformity of material distribution during long-term operation, reducing roller idling, and improving the overall crushing efficiency of the device.
