Description

Technical Field

[0001] The present invention relates to the field of heavy calcium carbonate production, and particularly to a waste residue recovery device for heavy calcium carbonate production. Background Art

[0002] The waste residue generated during the production of heavy calcium carbonate usually contains a certain amount of calcium carbonate residue. By using a specific waste residue recovery device, these waste residues can be processed and utilized again, reducing waste discharge and improving resource utilization rate. During the recovery process, the waste residues need to be crushed to facilitate subsequent processing.

[0003] In the existing waste residue recovery device for heavy calcium carbonate production, after pouring the waste residue of heavy calcium carbonate production into the grinding barrel, the waste residue of heavy calcium carbonate production is crushed and ground by the rotation of the grinding disc. However, after the grinding disc grinds the waste residue of heavy calcium carbonate production, it is difficult to make the waste residue of heavy calcium carbonate production be ground sufficiently, and it is easy to generate limestone waste residue, resulting in waste of subsequent raw materials and increasing production costs.

[0004] Therefore, a waste residue recovery device for heavy calcium carbonate production has been developed, which can perform secondary grinding on the waste residue of heavy calcium carbonate production, ensure that the waste residue of heavy calcium carbonate production is ground sufficiently, and avoid waste of subsequent raw materials. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing waste residue recovery device for heavy calcium carbonate production, which is difficult to make the waste residue of heavy calcium carbonate production be ground sufficiently, easy to generate limestone waste residue, resulting in waste of subsequent raw materials and increasing production costs, the present invention provides a waste residue recovery device for heavy calcium carbonate production, which can perform secondary grinding on the waste residue of heavy calcium carbonate production, ensure that the waste residue of heavy calcium carbonate production is ground sufficiently, and avoid waste of subsequent raw materials.

[0006] A waste residue recovery device for heavy calcium carbonate production includes a support base, an installation ring, a support frame, and a grinding mechanism. There are two support bases on the left and right. An installation ring is connected between the lower parts of the support bases. Support frames are connected to the upper sides of the left and right parts of the installation ring. A grinding mechanism capable of sufficiently grinding the waste residue of heavy calcium carbonate production is provided on the support frames.

[0007] Furthermore, the grinding mechanism for fully grinding the waste residue from heavy calcium carbonate production includes a rotating frame, a mounting cylinder, a first servo motor, a rotating shaft, and a grinding disc. The rotating frame is rotatably connected between the support frames. The mounting cylinder is connected to the rotating frame. The first servo motor is connected to the lower side of the mounting cylinder. The output shaft of the first servo motor is connected to the rotating shaft, and the rotating shaft is rotatably connected to the mounting cylinder. The grinding disc is connected to the middle of the rotating shaft. After all the waste residue from heavy calcium carbonate production falls to the lower part of the mounting cylinder, rotate the mounting cylinder to drive the rotating frame to rotate on the support frames, so that the mounting cylinder is turned upside down. Then start the first servo motor to make the grinding disc grind the waste residue from heavy calcium carbonate production again.

[0008] Furthermore, the edge of the grinding disc is thin and the middle is thick.

[0009] Furthermore, it also includes a filtering mechanism for filtering the waste residue from heavy calcium carbonate production. The filtering mechanism includes a tension spring, a sieve mesh, a connecting piece, a rotating piece, and a transmission frame. The sieve mesh is connected to the mounting ring through multiple tension springs. Multiple connecting pieces are connected to the upper side of the sieve mesh. The rotating piece is rotatably connected to the upper side of the mounting cylinder. The transmission frame is slidably connected to the upper part of the rotating shaft. After the mounting cylinder is turned upside down, the transmission frame automatically falls under the action of gravity. When the rotating shaft rotates, it drives the transmission frame to rotate, so that the transmission frame squeezes the rotating piece to rotate, and the rotating piece pushes the connecting piece to move, and the sieve mesh moves back and forth under the action of the tension spring.

[0010] Furthermore, it also includes a flipping mechanism for automatically flipping the mounting cylinder. The flipping mechanism includes a connecting seat, a second servo motor, a transmission belt, a worm, and a worm gear. The connecting seats are connected to the upper parts of the support frames. The second servo motors are connected to the middle parts of the connecting seats. The worms are rotatably connected to the upper parts of the connecting seats. The second servo motors and the adjacent worms are wound with a transmission belt through pulleys. The worm gears are connected to the left and right parts of the rotating frame, and the worm gears are meshed with the adjacent worms. Start the second servo motors on the connecting seats. Through the transmission of the pulleys and the transmission belt, drive the worms to rotate, so that the worms and the worm gears engage in motion, drive the rotating frame to rotate, and make the mounting cylinder rotate.

[0011] Furthermore, it also includes a stirring mechanism for stirring the waste residue from heavy calcium carbonate production. The stirring mechanism includes elastic pieces, springs, swinging pieces, and stirring pieces. Multiple elastic pieces are connected to the inner part of the lower side of the mounting cylinder. The swinging pieces are connected to the elastic pieces through springs. The stirring piece is connected to the lower part of the rotating shaft. The swinging pieces are in extrusion cooperation with the stirring piece. While the stirring piece rotates, it squeezes the swinging pieces. Through the action of the springs, the swinging pieces swing back and forth to strike the elastic pieces, making the elastic pieces vibrate.

[0012] Furthermore, it further includes an auxiliary crushing mechanism for crushing the heavy calcium carbonate production waste residue of large particles. The auxiliary crushing mechanism includes a fixed block and a rotating plate. A plurality of fixed blocks are connected to the inner side of the upper part of the installation cylinder, and a plurality of rotating plates are connected to the upper side of the grinding disc. While the grinding disc rotates, it drives the rotating plate to rotate, so that the rotating plate cooperates with the fixed block to crush the heavy calcium carbonate production waste residue of large particles.

[0013] Furthermore, it further includes an adsorption mechanism for adsorbing the heavy calcium carbonate production waste residue. The adsorption mechanism includes a connecting frame and an electrostatic adsorption plate. Connecting frames are connected to the mutually close sides of the lower part of the support frame, and electrostatic adsorption plates are connected to the mutually close sides of the connecting frames. When an electric current is passed into the electrostatic adsorption plates on the connecting frames, when the heavy calcium carbonate production waste residue falls onto the screen, the lifted heavy calcium carbonate production waste residue is adsorbed on the electrostatic adsorption plates.

[0014] The beneficial effects of the present invention are as follows: 1. By rotating the installation cylinder of the present invention, driving the rotating frame to rotate on the support frame, turning the installation cylinder upside down, and then starting the first servo motor, the grinding disc grinds the heavy calcium carbonate production waste residue again, achieving the effect of being able to perform secondary grinding on the heavy calcium carbonate production waste residue, ensuring sufficient grinding of the heavy calcium carbonate production waste residue, and avoiding waste of subsequent raw materials.

[0015] 2. When the rotating shaft rotates in the present invention, it drives the transmission frame to rotate, so that the transmission frame squeezes the rotating part to rotate, enabling the rotating part to push the connecting part to move, and making the screen move back and forth through the acting force of the tension spring, achieving the effect of being able to perform vibration filtration on the ground heavy calcium carbonate production waste residue and improving the recovery efficiency of the heavy calcium carbonate production waste residue.

[0016] 3. By starting the second servo motor on the connecting seat in the present invention, driving the worm to rotate through the transmission of the pulley and the transmission belt, making the worm engage with the worm gear to move, driving the rotating frame to rotate, and making the installation cylinder rotate, achieving the effect of being able to automatically turn over the installation cylinder, saving manpower and improving the grinding efficiency of the heavy calcium carbonate production waste residue.

[0017] 4. While the stirring part rotates in the present invention, it squeezes the swinging part, and through the acting force of the spring, the swinging part swings back and forth to strike the elastic sheet, making the elastic sheet vibrate and driving the installation cylinder to vibrate, achieving the effect of being able to stir the heavy calcium carbonate production waste residue and avoiding waste caused by the heavy calcium carbonate production waste residue adhering to the inner wall of the installation cylinder.

[0018] 5. While the grinding disc rotates in the present invention, it drives the rotating plate to rotate, so that the rotating plate cooperates with the fixed block to crush the heavy calcium carbonate production waste residue of large particles, achieving the effect of being able to avoid incomplete crushing of the heavy calcium carbonate production waste residue from affecting the grinding efficiency.

[0019] 6. By passing an electric current into the electrostatic adsorption plate on the connecting frame, when the waste residue from heavy calcium carbonate production falls onto the screen, the lifted waste residue from heavy calcium carbonate production is adsorbed onto the electrostatic adsorption plate, achieving the effects of improving the recycling rate of the waste residue from heavy calcium carbonate production and reducing environmental pollution.

Detailed implementation mode

[0033] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which the presently preferred embodiments of the invention are shown. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the invention to those skilled in the art.

[0034] A waste residue recovery device for heavy calcium carbonate production, as Figure 1 and Figure 2 shown, includes a support base 1, a mounting ring 2, a support frame 3 and a grinding mechanism 4. There are two support bases 1 on the left and right. An mounting ring 2 is connected between the lower parts of the support bases 1. Support frames 3 are connected to the upper sides of the left and right parts of the mounting ring 2, and a grinding mechanism 4 is provided on the support frames 3.

[0035] As Figures 1 - 5 shown, the grinding mechanism 4 includes a rotating frame 40, a mounting cylinder 41, a first servo motor 42, a rotating shaft 43 and a grinding disc 44. A rotating frame 40 is rotatably connected between the support frames 3. A mounting cylinder 41 is connected to the rotating frame 40. A first servo motor 42 is connected to the lower side of the mounting cylinder 41. A rotating shaft 43 is connected to the output shaft of the first servo motor 42. The rotating shaft 43 is rotatably connected to the mounting cylinder 41. A grinding disc 44 is connected to the middle of the rotating shaft 43. The edge of the grinding disc 44 is thin and the middle is thick, which is convenient for moving the waste residue of heavy calcium carbonate production into the gap between the grinding disc 44 and the mounting cylinder 41 for grinding.

[0036] When using the present invention, first place the support base 1 in the recovery area of the waste residue from heavy calcium carbonate production. Support the support frame 3 through the mounting ring 2. Then pour a certain amount of waste residue from heavy calcium carbonate production into the mounting cylinder 41. After that, start the first servo motor 42 to drive the rotating shaft 43 to rotate, so that the grinding disc 44 rotates. The waste residue from heavy calcium carbonate production is ground by the cooperation of the grinding disc 44 and the mounting cylinder 41. The ground waste residue from heavy calcium carbonate production falls to the lower part of the mounting cylinder 41. After all the waste residue from heavy calcium carbonate production has fallen to the lower part of the mounting cylinder 41, rotate the mounting cylinder 41 to drive the rotating frame 40 to rotate on the support frame 3, so that the mounting cylinder 41 is turned over and inverted. Then start the first servo motor 42 to make the grinding disc 44 grind the waste residue from heavy calcium carbonate production again. Thus, it can grind the waste residue from heavy calcium carbonate production twice, ensure that the waste residue from heavy calcium carbonate production is fully ground, and avoid waste of subsequent raw materials.

[0037] As Figure 1 , Figure 6 and Figure 7 shown, it further includes a filtering mechanism 5. The filtering mechanism 5 includes a tension spring 50, a screen 51, a connecting piece 52, a rotating piece 53 and a transmission frame 54. The screen 51 is connected to the mounting ring 2 through eight tension springs 50. Two connecting pieces 52 are connected to the upper side of the screen 51. The rotating piece 53 is rotatably connected to the upper side of the mounting cylinder 41. The upper part of the rotating shaft 43 is slidably connected to the transmission frame 54.

[0038] When using the filtering mechanism 5 of this equipment, the waste residue from heavy calcium carbonate production can be filtered. After the mounting cylinder 41 is turned over and inverted, the transmission frame 54 automatically falls under the action of gravity. When the rotating shaft 43 rotates, it drives the transmission frame 54 to rotate, so that the transmission frame 54 squeezes the rotating piece 53 to rotate, making the rotating piece 53 push the connecting piece 52 to move. Due to the acting force of the tension spring 50, the screen 51 moves back and forth. Then the waste residue from heavy calcium carbonate production after secondary grinding falls onto the screen 51. The waste residue from heavy calcium carbonate production that meets the grinding standard passes through the screen 51, and the waste residue from heavy calcium carbonate production with larger particles is left on the screen 51. Thus, it can vibrate and filter the waste residue from heavy calcium carbonate production after grinding, and improve the recovery efficiency of the waste residue from heavy calcium carbonate production.

[0039] As Figure 1 , Figure 8 and Figure 9As shown, it further includes a flipping mechanism 6. The flipping mechanism 6 includes a connecting seat 60, a second servo motor 61, a transmission belt 62, a worm 63, and a worm gear 64. Connecting seats 60 are connected to the upper part of the support frame 3. Second servo motors 61 are connected to the middle of the connecting seats 60. Worms 63 are rotatably connected to the upper part of the connecting seats 60. Transmission belts 62 are wound around between the second servo motors 61 and the adjacent worms 63 through pulleys. Worm gears 64 are connected to the left and right parts of the rotating frame 40, and the worm gears 64 are engaged with the adjacent worms 63.

[0040] By using the flipping mechanism 6 of this device, the installation cylinder 41 can be automatically flipped. When it is necessary to flip the installation cylinder 41, the second servo motor 61 on the connecting seat 60 is started. Driven by the pulley and the transmission belt 62, the worm 63 is driven to rotate, so that the worm 63 meshes with the worm gear 64 to move, driving the rotating frame 40 to rotate, and making the installation cylinder 41 rotate. Thus, it can automatically flip the installation cylinder 41, saving labor and improving the grinding efficiency of the waste residue of heavy calcium carbonate production.

[0041] As Figure 2 and Figure 10 As shown, it further includes a stirring mechanism 7. The stirring mechanism 7 includes elastic pieces 70, springs 71, swinging pieces 72, and stirring pieces 73. Two elastic pieces 70 are connected to the inner part of the lower side of the installation cylinder 41. Swinging pieces 72 are connected to the elastic pieces 70 through springs 71. Stirring pieces 73 are connected to the lower part of the rotating shaft 43, and the swinging pieces 72 are in extrusion fit with the stirring pieces 73.

[0042] By using the stirring mechanism 7 of this device, the waste residue of heavy calcium carbonate production can be stirred. While the rotating shaft 43 rotates, it drives the stirring pieces 73 to rotate, so that the stirring pieces 73 stir the waste residue of heavy calcium carbonate production. While the stirring pieces 73 rotate, they squeeze the swinging pieces 72. Through the acting force of the springs 71, the swinging pieces 72 swing back and forth to strike the elastic pieces 70, making the elastic pieces 70 vibrate, driving the installation cylinder 41 to vibrate, and making the waste residue of heavy calcium carbonate production attached to the installation cylinder 41 fall off. Thus, it can stir the waste residue of heavy calcium carbonate production and avoid waste caused by the waste residue of heavy calcium carbonate production adhering to the inner wall of the installation cylinder 41.

[0043] As Figure 2 and Figure 11 As shown, it further includes an auxiliary crushing mechanism 8. The auxiliary crushing mechanism 8 includes fixing blocks 80 and rotating plates 81. A plurality of fixing blocks 80 are connected to the inner side of the upper part of the installation cylinder 41. Thirty rotating plates 81 are connected to the upper side of the grinding disc 44.

[0044] Using the auxiliary crushing mechanism 8 of the present device, large-particle heavy calcium carbonate production waste residues can be crushed. While the grinding disc 44 rotates, it drives the rotating plate 81 to rotate, so that the rotating plate 81 and the fixed block 80 cooperate to crush the large-particle heavy calcium carbonate production waste residues, thus playing a role in avoiding the incomplete crushing of the heavy calcium carbonate production waste residues and affecting the grinding efficiency.

[0045] As Figure 1 and Figure 12 shown, it further includes an adsorption mechanism 9. The adsorption mechanism 9 includes a connecting frame 90 and an electrostatic adsorption plate 91. Connecting frames 90 are connected to the lower sides of the support frame 3 close to each other, and electrostatic adsorption plates 91 are connected to the sides of the connecting frames 90 close to each other.

[0046] Using the adsorption mechanism 9 of the present device, the heavy calcium carbonate production waste residues can be adsorbed. When an electric current is passed into the electrostatic adsorption plates 91 on the connecting frames 90, when the heavy calcium carbonate production waste residues fall onto the screen 51, the lifted heavy calcium carbonate production waste residues are adsorbed on the electrostatic adsorption plates 91, thus playing a role in improving the recycling rate of the heavy calcium carbonate production waste residues and reducing environmental pollution.

[0047] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation mode of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
