Description

Technical Field

[0001] The present invention relates to the technical field of cement ball mills, and particularly to a dust-removing and environmentally friendly cement ball mill. Background Art

[0002] A cement ball mill is a device used in cement plants to grind cement products and raw materials into powder. It can also be used for ore grinding in industrial and mining enterprises such as metallurgy, chemical industry, and electric power. During the process of powdering cement, the cement material is evenly fed into the cylinder through a spiral auger from the feeding port. Liners are installed on the inner wall of the cylinder, and steel balls are placed inside the cylinder. The centrifugal force generated by the rotation of the cylinder brings the steel balls to a certain height and then they fall, using the impact of the steel balls on the cement material for heavy hitting and grinding. The powdered material finally exits from the discharge port.

[0003] Among them, the number of liners in the cylinder is several, and they are spliced in pairs to cover the inner wall of the cylinder to protect the inner wall of the cylinder from the impact of steel balls. The liners are usually installed by bolts passing through the side wall of the cylinder. Due to the large volume and heavy weight of the liners, it is labor-consuming and time-consuming to carry and splice them inside the cylinder, resulting in the problem of too low installation efficiency of the liners. Moreover, due to the long-term use of the liners, wear and bolt loosening will occur, leading to liner loosening. Once the liner is loosened, its surface is not flush with the adjacent liner, and it is extremely easy to cause the liner to break when the steel balls move. The existing ball mills can only rely on manual regular quality inspection to tighten the bolts and cannot detect bolt loosening. In addition, the material flow at the feeding port and discharge port of the ball mill is likely to cause dust to float, resulting in air pollution in the cement plant workshop. The traditional dust removal method is to install a workshop dust collector. For a large-space workshop, a large dust collector needs to be used, which undoubtedly increases the dust removal cost of cement grinding. Summary of the Invention

The number of the guiding protrusions is several and they are arranged at equal intervals along the inner wall of the cylinder body. The position of the guiding protrusion corresponds to the central axis of the lining plate.

[0012] Preferably, the water storage base is in the shape of an annular ring with a hollow interior or a rectangular box with a hollow interior.

The water storage base is integrally connected to the water intake base, and the highest water level height in the water storage base is lower than the lowest water level height in the water intake base.

[0013] Preferably, the inner cavities of the water storage base and the water intake base are communicated through a water passing port. The water passing port is circular. The piston forms a sliding connection with the inner wall of the water passing port within the water passing port. The telescopic cylinder is installed on the outer surface wall of the water storage base, and the telescopic end of the telescopic cylinder is connected to the piston.

[0014] Preferably, the number of the atomizing nozzles is several and they are arranged at equal intervals circumferentially along the outer side wall of the cylinder body. The atomizing nozzles penetrate through the sound insulation pad and are communicated with the hollow groove. The water outlet of the water pump is communicated with the hollow groove through a water pipe.

[0015] Preferably, the first bolt sequentially penetrates through the lining plate, the guiding protrusion and the side wall of the cylinder body through the installation hole and is threadedly connected to the first nut. The lining plate is bolted to the cylinder body through the first bolt.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. For this dust-removing and environmentally friendly cement ball mill, by setting the guiding protrusion and the lining plate installation mechanism, by adding guiding protrusions on the inner wall of the cylinder body, a first groove is opened at the bottom of the lining plate. During the process of installing the lining plate on the inner wall of the cylinder body, the lining plate is placed on the guiding protrusion so that the guiding protrusion is inserted into the first groove. The lifting cylinder extends, and the lifting cylinder drives the vertical rod to drive the push plate to move downward, so that the push plate is placed on one side of the lining plate. Then, in cooperation with the start of the driving cylinder, the driving cylinder drives the vertical rod to drive the push plate to move towards the other side of the cylinder body, so that the push plate pushes the lining plate to move from one side of the cylinder body to the other side for stacking and splicing, realizing the automatic stacking function of the lining plate. There is no need for manual handling of the lining plate. Through the insertion of the guiding protrusion into the first groove, it is used not only to position the installation position of the lining plate but also to guide the sliding of the lining plate on the inner wall of the cylinder body, making the installation of the inner lining plate of the cylinder body more time-saving and labor-saving.

[0018] 2. For the dust-removing and environmentally friendly cement ball mill of the present invention, when installing the lining plate on the inner wall of the bottom of the cylinder body by setting the positioning frame and the second bolt, on one side of this position, the lining plate has been installed, while on the other side, it has not. By placing the positioning frame on the guiding protrusion on the side where the lining plate has not been installed, at this time, the guiding protrusion is inserted into the second groove, and the positioning frame drives the second bolt to penetrate through the installation hole. By sleeving a second nut at the bottom of the second bolt, the positioning frame is stably installed inside the cylinder body. In response to the change in the installation position of the lining plate inside the cylinder body, the installation position of the positioning frame is changed, so that the positioning frame is sequentially installed along the inner wall of the cylinder body, achieving the effect of rapid disassembly and assembly of the positioning frame.

[0019] 3. For the dust-removing and environmentally friendly cement ball mill of the present invention, during the process of installing the lining plate on the inner wall of the cylinder body by passing the first bolt through the lining plate, the first bolt drives the fixing block to penetrate through the lining plate and insert into the slot. The fixing block slides in the slot and enters the chute. As the first bolt is advanced and connected to the first nut, the fixing block pushes the slider to slide in the chute, causing the slider to compress the spring. At the same time, the slider drives the insertion rod to extend out of the through hole. When the first nut becomes loose or the lining plate wears and causes the first bolt to become loose, the first bolt is easily pushed back in the installation hole by the elastic force of the spring, resulting in the insertion rod retracting into the through hole. The telescopic state of the colored insertion rod facilitates the staff to visually observe whether the first bolt is in a tightened state, achieving the effect of detecting the loosening of the first bolt and facilitating the staff to perform maintenance in a timely manner.

[0020] 4. For the dust-removing and environmentally friendly cement ball mill of the present invention, by setting the hollow groove and the atomizing nozzles, the water stored in the water storage base is introduced into the hollow groove through the water pipe by the water pump. The water flows in the hollow groove and then sprays out from several atomizing nozzles, so that the atomizing nozzles spray water mist into the air during the rotation of the cylinder body. The dust is removed by the water mist fusing with the dust during the falling process. By borrowing the driving force of the rotation of the cylinder body, the atomizing nozzles perform rotary spraying, covering a large range of space in the workshop centered on the ball mill for dust removal. Compared with the traditional method of using dust collectors in the workshop, the dust removal cost and energy consumption are greatly reduced, making the dust removal function of the ball mill more environmentally friendly.

[0021] 5. For the dust-removing and environmentally friendly cement ball mill of the present invention, by setting the rotary water replenishing mechanism, during the process of the cylinder body rotating to grind cement, it drives the water storage base and the water intake base to rotate. The water intake base scoops the water in the water tank into the inner cavity as it passes through the water tank. As the water intake base rotates and rises, the telescopic cylinder contracts and pulls the piston to move in the water passage opening, canceling the sealing effect of the piston on the water passage opening, so that the water in the water intake base flows into the water storage base through the water passage opening. When the water intake base rotates to the upper part of the cylinder body, the telescopic cylinder extends, pushing the piston to seal the water passage opening again, completing a single water intake. By borrowing the rotation of the water intake base along with the cylinder body to transfer the water in the water tank to the water storage base for collection, it is convenient for the atomizing nozzles to replenish water for dust removal.

[0034] As Figures 1 to 8 shown, the dust removal and environmental protection cement ball mill of this embodiment includes a cylinder body 1, a feeding port 2 installed on one side of the cylinder body 1, a discharging port 3 installed on the other side of the cylinder body 1, bearing seats 4 installed on the feeding port 2 and the discharging port 3, a frame 5 installed at the bottom of the bearing seats 4, and a driving motor 6 installed below the cylinder body 1. The driving motor 6 is connected to the cylinder body 1 through a gear set to drive the cylinder body 1 to rotate. The inner wall of the cylinder body 1 is provided with guiding protrusions 11. The surface of the guiding protrusions 11 is smooth and is used for the installation positioning and transportation guiding of the lining plate 7. The inner wall of the cylinder body 1 is provided with the lining plate 7. The lining plate 7 is usually in the shape of an arc plate and has a number of them. They are spliced and laid on the inner wall of the cylinder body 1 to protect the cylinder body 1 from being deformed by the impact of steel balls. A first groove 71 is opened on one side of the lining plate 7 close to the inner wall of the cylinder body 1. An installation hole 12 is penetrated through the side wall of the cylinder body 1 and the middle of the guiding protrusion 11. A first bolt 8 is penetrated through the inside of the installation hole 12. A first nut 81 is sleeved outside the first bolt 8. The first bolt 8 and the first nut 81 are connected to install the lining plate 7 on the inner wall of the cylinder body 1. A hollow groove 13 is opened inside the side wall of the cylinder body 1. A sound insulation pad 14 is laid outside the hollow groove 13. The sound insulation pad 14 is used for noise reduction inside the cylinder body 1. An atomizing nozzle 15 is installed on the side wall of the cylinder body 1. The position of the atomizing nozzle 15 on the outer surface wall of the cylinder body 1 is staggered from the first bolt 8. A sliding groove 16 is opened in the middle of the installation hole 12. A loosening detection mechanism 9 is installed inside the sliding groove 16 and is used for detecting the loosening of the first bolt 8. A lining plate installation mechanism 20 is installed inside the cylinder body 1 and is used for assisting in installing the lining plate 7. A rotating water replenishing mechanism 21 is installed outside one end of the cylinder body 1 close to the feeding port 2. A water tank 22 is installed on the upper surface of the frame 5 below the rotating water replenishing mechanism 21. Clear water is stored inside the water tank 22;

[0035] The liner mounting mechanism 20 includes a mounting frame 201. Inside the mounting frame 201, a driving cylinder 202 is mounted. The actual model of the driving cylinder 202 is selected according to the actual size of the mounting frame 201. The driving cylinder 202 and the lifting cylinder 205 are connected to an external power supply and a gas source through circuits and lines, and are controlled to open and close by the main control center of the ball mill. A vertical rod 203 is disposed through the middle of the moving member of the driving cylinder 202. The vertical rod 203 is movably connected to the moving member of the driving cylinder 202. A push plate 204 is connected to the bottom of the vertical rod 203. A lifting cylinder 205 is connected to the top of the vertical rod 203. The actual model of the lifting cylinder 205 is selected according to the required actual telescopic length of the push plate 204. One side of the mounting frame 201 is connected to a positioning frame 206. The positioning frame 206 is mounted on the side walls at both ends of the mounting seat and is used to mount both ends of the mounting frame 201 on the cylinder body 1. A second groove 207 is formed at the bottom of the positioning frame 206. A second bolt 208 is connected to the bottom of the positioning frame 206. A second nut 209 is sleeved on the bottom end of the second bolt 208. The positioning frame 206 is mounted on the inner wall of the cylinder body 1 by connecting the second bolt 208 through the cylinder body 1 and the second nut 209.

[0036] The rotary water replenishing mechanism 21 includes a water storage seat 211 for transferring the water for spray dust removal. One side of the water storage seat 211 is connected to a water intake seat 212 for transferring the water in the water tank 22 to the water storage seat 211. A water passage 213 is formed between the water storage seat 211 and the water intake seat 212. A piston 214 is disposed inside the water passage 213. One side of the piston 214 is connected to a telescopic cylinder 215. The telescopic cylinder 215 is electrically connected to the main control center of the ball mill through a circuit. The actual model of the telescopic cylinder 215 is selected according to the actual size of the water storage seat 211. The telescopic end of the telescopic cylinder 215 penetrates through the side wall of the water passage 213 and inserts into the water passage 213. An opening 216 is formed on one side of the water intake seat 212. A water pump 217 is mounted on one side of the water storage seat 211. The water pump 217 is mounted on the outer side wall of the cylinder body 1. A water pipe 218 is connected between the water pump 217 and the water storage seat 211. The water inlet of the water pump 217 is connected to the water storage seat 211 through the water pipe 218, and the water outlet is connected to the hollow groove 13 through the water pipe 218.

[0037] Specifically, a through hole 17 is formed on one side of the sliding groove 16, and a slot 18 is formed on the other side of the sliding groove 16. Fixed blocks 82 are connected to both side walls of the first bolt 8. The width dimension of the fixed blocks 82 is adapted to the inner wall width dimension of the slot 18. One side of the sliding groove 16 communicates with the through hole 17, and the other side communicates with the slot 18. The fixed blocks 82 are in the shape of rectangular blocks. The fixed blocks 82 are inserted into the sliding groove 16 through the slot 18 and contact the slider 91. The slider 91 is pushed to slide in the sliding groove 16 by inserting the fixed blocks 82 into the sliding groove 16.

[0038] Furthermore, the loosening detection mechanism 9 includes a slider 91. One side of the slider 91 is connected with a plug rod 92. The middle part of the side of the slider 91 close to the plug rod 92 is connected with a spring 93. Both ends of the spring 93 are connected with the inner wall of the chute 16 and the slider 91 respectively. When the spring 93 is in a normal tensile state, the plug rod 92 retracts into the through hole 17. The slider 91 is in a circular ring shape and is slidably connected with the inner wall of the chute 16. The plug rod 92 passes through the through hole 17 and extends out from the outer side wall of the cylinder body 1. During the process of installing the first bolt 8 through the lining plate 7 and fixing it on the inner wall of the cylinder body 1, the first bolt 8 drives the fixing block 82 to penetrate through the lining plate 7 and insert into the slot 18. The fixing block 82 slides into the chute 16 in the slot 18. As the first bolt 8 advances and is connected with the first nut 81, the fixing block 82 pushes the slider 91 to slide in the chute 16, causing the slider 91 to compress the spring 93. At the same time, the slider 91 drives the plug rod 92 to extend out from the through hole 17. The surface of the plug rod 92 is coated with colored paint. Through the telescopic state of the colored plug rod 92, it is convenient for the staff to visually observe whether the first bolt 8 is in a tightened state, achieving the effect of detecting the loosening of the first bolt 8.

[0039] Furthermore, the mounting frame 201 is in the shape of a rectangular frame and is integrally connected with the positioning frame 206. The top of the second bolt 208 is connected with the positioning frame 206. After the positioning frame 206 is installed on the adjacent guiding protrusion 11, at this time, the mounting frame 201 is in a horizontal state. According to the number of columns of the lining plate 7 installed on the cylinder body 1, the included angle between the positioning frame 206 and the mounting frame 201 is customized. The bottom of the second bolt 208 penetrates through the mounting hole 12 on the cylinder body 1 and is threadedly connected with the second nut 209. The positioning frame 206 is bolted to the cylinder body 1 through the second bolt 208, achieving the effect of quickly disassembling and assembling the positioning frame 206. The installation position of the positioning frame 206 can be changed according to the change of the installation position of the lining plate 7 on the cylinder body 1, so that the positioning frame 206 is installed successively along the inner wall of the cylinder body 1 to assist in the stacking and splicing of the lining plate 7.

[0040] Furthermore, the guiding protrusion 11 is in the shape of a long strip plate with an arc-shaped surface. The surface of the guiding protrusion 11 is polished smoothly. The guiding protrusion 11 is integrally connected with the cylinder body 1. The guiding protrusion 11 is movably inserted into the lining plate 7 through the first groove 71 and movably inserted into the positioning frame 206 through the second groove 207. The number of guiding protrusions 11 is several and they are arranged at equal intervals along the inner wall of the cylinder body 1. The position of the guiding protrusion 11 corresponds to the central axis of the lining plate 7. The number of guiding protrusions 11 corresponds to the number of columns of the lining plate 7 installed inside the cylinder body 1. By placing the lining plate 7 on the guiding protrusion 11 and inserting the guiding protrusion 11 into the first groove 71, the lining plate 7 is pushed by the push plate 204 in the lining plate installation mechanism 20 to move from one side of the cylinder body 1 to the other side for stacking and splicing, realizing the automatic stacking function of the lining plate 7. There is no need for manual handling of the lining plate 7. The guiding protrusion 11 is both used to position the installation position of the lining plate 7 and to guide the movement of the lining plate 7 on the inner wall of the cylinder body 1, making the installation of the lining plate 7 on the inner wall of the cylinder body 1 more time-saving and labor-saving.

[0041] Further, the water storage base 211 is in the shape of an internally hollow circular ring, and the water storage base 211 is in the shape of an internally hollow rectangular box. The number of water intake bases 212 is several, and they are arranged at equal circumferential intervals along the outer side of the water storage base 211. Both the water intake base 212 and the water storage base 211 are installed on the outer side of the cylinder body 1. The water storage base 211 and the water intake base 212 are integrally connected, and the highest water level height in the water storage base 211 is lower than the lowest water level height in the water intake base 212. When the water intake base 212 rotates and moves above the cylinder body 1 along with the cylinder body 1, all the water in the water intake base 212 will flow into the water storage base 211 under the action of gravity.

[0042] Further, the inner cavities of the water storage base 211 and the water intake base 212 are connected through a water passage port 213. The water in the water intake base 212 flows into the water storage base 211 from the water passage port 213. The water passage port 213 is circular. A piston 214 forms a sliding connection with the inner wall of the water passage port 213 within the water passage port 213. A telescopic cylinder 215 is installed on the outer surface wall of the water storage base 211, and the telescopic end of the telescopic cylinder 215 is connected to the piston 214. When the water intake base 212 passes through the water tank 22, the water in the water tank 22 is scooped into the inner cavity. As the water intake base 212 rotates and rises, the telescopic cylinder 215 contracts to pull the piston 214 to move within the water passage port 213, canceling the sealing effect of the piston 214 on the water passage port 213, so that the water in the water intake base 212 flows into the water storage base 211 from the water passage port 213. When the water intake base 212 rotates above the cylinder body 1, the telescopic cylinder 215 extends to push the piston 214 to re-seal the water passage port 213, completing a single water intake.

[0043] Further, the number of atomizing nozzles 15 is several, and they are arranged at equal circumferential intervals along the outer side wall of the cylinder body 1. The atomizing nozzles 15 penetrate through the sound insulation pad 14 and are connected to the hollow groove 13. The water outlet of the water pump 217 is connected to the hollow groove 13 through a water pipe 218. The water pump 217 pumps the water in the water storage base 211 into the hollow groove 13 through the water pipe 218, and finally the water flows out from the atomizing nozzles 15. Since the water pump 217 rotates along with the cylinder body 1, and the water flow in the water storage base 211 is not always full, when the water pump 217 moves to the uppermost position of the cylinder body 1, the water pipe 218 connected to the water inlet of the water pump 217 cannot touch the water level in the water storage base 211. At this time, there is no water at the water inlet of the water pump 217, but as the water pump 217 rotates and moves downward, the water inlet re-enters water, which does not affect the water spraying of the atomizing nozzles 15.

[0044] Furthermore, the first bolt 8 passes through the lining plate 7, the guiding protrusion 11 and the side wall of the cylinder body 1 in sequence through the mounting hole 12 and is threadedly connected to the first nut 81. The lining plate 7 is bolted to the cylinder body 1 through the first bolt 8. A number of lining plates 7 are all installed on the inner wall of the cylinder body 1 through the first bolt 8.

[0045] The usage method of this embodiment is as follows: When the user actually uses the cement ball mill to grind cement raw materials, first install the lining plate 7 on the inner wall of the cylinder body 1. Use a forklift to transport the lining plate 7 into the cylinder body 1. Place the lining plate 7 to be installed on one end of the guiding protrusion 11, and place the positioning frame 206 on the right side of the lining plate 7. At this time, the second groove 207 at the bottom of the positioning frame 206 is placed on the adjacent right guiding protrusion 11. The positioning frame 206 drives the second bolt 208 to penetrate the installation hole 12, and then sleeve the second nut 209 at the bottom of the second bolt 208 from the outside of the cylinder body 1 and rotate it to tighten, so that the positioning frame 206 is stably installed in the cylinder body 1. Then, the outer circuits and air circuits of the lining plate installation mechanism 20 are started. The lifting cylinder 205 extends, and the lifting cylinder 205 pushes the vertical rod 203 to drive the push plate 204 to move downward, so that the push plate 204 is placed on one side of the lining plate 7. Then, in cooperation with the start of the driving cylinder 202, the driving cylinder 202 drives the vertical rod 203 to drive the push plate 204 to move towards the other side of the cylinder body 1. The push plate 204 pushes the lining plate 7 to move from one side of the cylinder body 1 to the other side for stacking and splicing. Repeat the above operation to splice the lining plates 7 on this guiding protrusion 11 one by one. After splicing, the staff inserts the first bolt 8 through the lining plate 7 into the installation hole 12. The first bolt 8 drives the fixing block 82 to penetrate the lining plate 7 and insert it into the slot 18. The fixing block 82 slides in the slot 18 and enters the chute 16. As the first bolt 8 is pushed forward and connected to the first nut 81, the staff outside the cylinder body 1 rotates the first nut 81 to tighten it. At the same time, the fixing block 82 pushes the slider 91 to slide in the chute 16, so that the slider 91 compresses the spring 93. The slider 91 drives the insertion rod 92 to extend from the through hole 17. After installation, hoist the cylinder body 1 and rotate it clockwise, so that a row of installed lining plates 7 moves to the left to change the installation position, loosen the second nut 209 and move the positioning frame 206 one row to the right and refix it, and then continue to install the next row of lining plates 7. According to the change of the installation position of the lining plate 7 on the inner wall of the cylinder body 1, change the installation position of the positioning frame 206 until the lining plate 7 completely covers the inner wall of the cylinder body 1, then take out the lining plate installation mechanism 20. When grinding cement, the cement raw materials are fed into the cylinder body 1 from the feeding port 2. The rotation of the cylinder body 1 drives the internal steel balls to rotate, so that the steel balls impact the cement raw materials in the cylinder body 1 to break them into fine powders. Finally, the ground cement powder is discharged from the discharge port 3. During the rotation of the cylinder body 1, it drives the water storage seat 211 and the water intake seat 212 to rotate. The water intake seat 212 scoops the water in the water tank 22 into the inner cavity when passing through the water tank 22. As the water intake seat 212 rotates and rises, the main control center controls the telescopic cylinder 215 to contract and pull the piston 214 to move in the water passing port 213, canceling the sealing effect of the piston 214 on the water passing port 213, so that the water in the water intake seat 212 flows into the water storage seat 211 from the water passing port 213. When the water intake seat 212 rotates above the cylinder body 1, the telescopic cylinder 215 extends, pushing the piston 214 to seal the water passing port 213 again. Borrowing the rotation of the water intake seat 212 with the cylinder body 1, the water in the water tank 22 is transferred to the water storage seat 211 for collection.Meanwhile, the water pump 217 passes the water stored in the water storage base 211 into the hollow groove 13 through the water pipe 218. The water flows through the hollow groove 13 and then sprays out from several atomizing nozzles 15, so that the atomizing nozzles 15 spray water mist into the air during the rotation of the cylinder 1. The water mist fuses with dust during the falling process to achieve the effect of dust removal. When the first nut 81 is loose or the lining plate 7 is worn, causing the first bolt 8 to become loose, the first bolt 8 is easily pushed back by the resilience of the spring 93 and retracts in the installation hole 12, resulting in the insertion rod 92 retracting into the through hole 17. At this time, the staff can directly observe the retraction of the colored insertion rod 92 and know in time that the first bolt 8 at this place is loose, which is convenient for the staff to maintain in time.
