Abstract

This invention relates to the field of cement production technology and discloses a grinding device for cement production, including a grinding box and a vibration mechanism disposed inside the grinding box. The vibration box drives a sloping plate to vibrate synchronously, causing material falling onto the sloping plate to be evenly distributed between several limiting plates during the vibration process, and then slides down the inclined surface of the sloping plate onto a discharge plate. Simultaneously, the vibration box also drives the discharge plate to vibrate a second time, further improving the uniformity of material distribution. After two even dispersions, the material falls smoothly onto a discharge plate under the vibration of the discharge plate and rolls down the inclined surface of the discharge plate into the grinding area between two grinding rollers.

Description

Technical Field

[0001] This invention relates to the field of cement production equipment technology, specifically a grinding device for cement production. Background Technology

[0002] In cement production, uniform feeding and stable grinding of materials are crucial for the quality control of the finished powder. Currently, commonly used grinding equipment typically includes a feeding structure, a vibration distribution structure, and a grinding roller pressing structure, but many shortcomings still exist in actual operation.

[0003] Traditional equipment lacks an effective dispersion and uniform material distribution mechanism before the material enters the grinding rollers, causing the material to fall in a concentrated manner, resulting in uneven force distribution between the grinding rollers. This uneven distribution not only affects the grinding efficiency, but also easily causes grooves, local depressions or uneven wear on the surface of the grinding rollers, thereby reducing the service life of the equipment and affecting the fineness consistency and quality stability of the finished powder.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention provides a grinding device for cement production. When the material is discharged from the feed box, it falls onto the inclined plate. At this time, the drive motor is started, and the drive motor drives the rotating rod to rotate. The rotating rod drives the rotating shaft and the synchronous rod to rotate synchronously through the linkage of the pulley and the synchronous belt. When the rotating shaft rotates, it drives the contact plate to rotate. When the contact plate contacts the isosceles trapezoidal block, it uses its edge to cooperate with the inclined surface of the isosceles trapezoidal block to push the isosceles trapezoidal block to move closer to the vibrating box, thereby causing the vibrating box to move. At this time, the limiting spring undergoes elastic deformation to absorb the impact and store the reset energy. When the contact plate leaves the isosceles trapezoidal block, the vibrating box quickly resets under the elastic force of the limiting spring. As the rotating shaft continues to rotate, the contact plate continuously pushes the isosceles trapezoidal block to rotate. The isosceles trapezoidal block enables the vibrating box to move continuously back and forth. The vibrating box drives the inclined plate to shake synchronously, so that the material falling on the inclined plate is evenly distributed between several limiting plates during the shaking process, and slides down the inclined plate to the feeding plate. At the same time, the vibrating box also drives the feeding plate to shake a second time, further improving the uniformity of material distribution. After two even distributions, the material falls smoothly into the discharge plate under the shaking action of the feeding plate, and rolls down the inclined plate to the grinding area between the two grinding rollers. This structure effectively avoids the appearance of grooves, local depressions or uneven wear on the surface of the grinding rollers due to uneven material distribution, thereby ensuring that the material can be efficiently and evenly ground into powder, improving grinding efficiency and product quality.

[0021] (2) The present invention provides a grinding device for cement production. Under the synergistic action of two synchronous gears, two grinding rollers rotate synchronously to efficiently grind the material falling between them. During the continuous rotation of the grinding rollers, the grooved scraper always maintains close contact with their surface, which can simultaneously scrape off the material cake and residual powder adhering to the surface of the grinding rollers, effectively preventing fluctuations in the fineness of the finished product caused by uneven material layer or blockage, thereby ensuring the quality stability of cement products. The material after being crushed by the grinding rollers falls into the collection box below and enters the conical grooved box from the collection box. At the same time, the synchronous rod drives the first gear to rotate during the rotation. The first gear drives the round rod further through the meshing transmission with the second gear. The rotating rod drives multiple agitators mounted on it to rotate synchronously. Inside the conical grooved box, the agitators continuously crush and disperse the material, fully decomposing the cake formed by the grinding rollers. This separates large particles from fine powder. Under the rotation of the agitators, smaller particles pass through the groove at the bottom of the conical grooved box, fall into the collection pipe below, and are eventually discharged from the system. Larger particles are retained in the upper layer, achieving effective classification of coarse and fine materials. This not only improves the uniformity of the finished powder and the discharge efficiency but also enables the timely separation of unqualified large particles, which is helpful for subsequent recycling and re-grinding or separate processing, thereby comprehensively improving the quality and production efficiency of cement products.

[0022] (3) In the grinding device for cement production of the present invention, during the rotation of the stirring frame, the centrifugal force generated will cause larger particles to rotate along the inner wall of the inclined surface of the conical grooved box. The larger the mass of the particles, the higher they will be thrown under the action of centrifugal force, and they will move upward along the inner wall of the conical grooved box. When these larger particles come into contact with several arc-shaped inclined plates during the rotation, since the length of the arc-shaped inclined plates closer to the top is shorter, the particles will be lifted again due to the guiding effect of the inclined surface when they collide or slide past the arc-shaped inclined plates, and will be thrown out of the conical grooved box under the action of inertia. The material is fed into the discharge pipe. Subsequently, these large particles that do not meet the fineness requirements enter the elevator through the discharge pipe and are then transported back to the feed box through the feed pipe to achieve circulating grinding, thereby effectively ensuring the consistency of the finished powder quality. In addition, during the process of the stirring frame driving the larger particles to swing, due to the asymmetrical distribution and different positions of multiple arc-shaped inclined plates in the conical grooved box, various unqualified particles of different quality and particle size can be effectively thrown out of the conical grooved box, further ensuring the complete separation between large particles and fine powder, improving the classification accuracy and the overall screening efficiency of the system.

[0023] (4) In the grinding device for cement production of the present invention, during the reciprocating movement of the vibrating box, the fixed rod will move synchronously. The fixed rod will further drive the rectangular fixed block to move. When the rectangular fixed block contacts the inclined surface of the isosceles trapezoidal limiting block, it will push the isosceles trapezoidal limiting block to slide upward under the action of the inclined surface, thereby driving the conical slider to rise. As the conical slider rises, part of its structure enters the inside of the feed box, causing the material in the feed box to fall into the arc-shaped inclined groove. At the same time, the conical slider will also drive the rectangular block to rise together. At this time, the return spring is compressed and undergoes elastic deformation to store the return energy. When the rectangular fixed block leaves the isosceles trapezoidal limiting block, under the elastic force of the return spring, the conical slider quickly... The material resets and moves downward, causing the arc-shaped chute to carry the material away from the feed box and slide down onto the inclined plate. During the continuous reciprocating motion of the conical slider, not only is quantitative control of the material in the feed box achieved, ensuring that only the appropriate amount of material enters the subsequent process each time, but its up-and-down movement also effectively clears the internal channels of the feed box, preventing material blockage and ensuring smooth feeding. After being evenly dispersed multiple times by the inclined plate and the discharge plate, the material can fall more stably and evenly into the grinding area between the two grinding rollers, significantly improving the grinding uniformity of the grinding rollers and further effectively preventing uneven grinding caused by uneven material distribution, thereby improving the stability of equipment operation and the quality of finished powder.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-8 As shown, the present invention is a grinding device for cement production, including a grinding box 1, and further comprising:

[0038] Vibration mechanism, used to ensure uniform material discharge during abrasive processing;

[0039] The separation mechanism is installed inside the grinding box 1. The separation mechanism includes two rotating rods 2 installed inside the grinding box 1. The separation mechanism is used to separate the unground granular material from the crushed material.

[0040] The material feeding mechanism is located above the grinding box 1. The material feeding mechanism includes a feed box 3 located above the grinding box 1. The material feeding mechanism is used to control the release speed and release amount of the material.

[0041] like Figure 1 and Figure 3 As shown, the vibration mechanism includes a support frame 101 fixedly installed at the bottom of the grinding box 1. Two C-shaped fixing frames 102 are fixedly installed on the grinding box 1. A vibration box 103 is provided above the grinding box 1. Telescopic rods 104 are fixedly installed on the sides of the two C-shaped fixing frames 102 that are close to each other. The ends of the two telescopic rods 104 that are close to each other are fixedly connected to the vibration box 103. Limiting springs 105 are respectively sleeved on the two telescopic rods 104. The ends of the two limiting springs 105 that are far from each other are fixedly connected to the two C-shaped fixing frames 102. The ends of the two limiting springs 105 that are close to each other are fixedly connected to the vibration box 103.

[0042] The isosceles trapezoidal block 112 is pushed to move closer to the vibration box 103, thereby causing the vibration box 103 to be displaced. At this time, the limit spring 105 undergoes elastic deformation to absorb the impact and store the reset energy.

[0043] like Figure 3 As shown, an inclined plate 106 is fixedly installed inside the vibration box 103, and several limiting plates 107 are fixedly installed on the surface of the inclined plate 106. A discharge plate 108 is fixedly installed on the inner wall of the vibration box 103, and a discharge plate 109 is fixedly installed on the top of the grinding box 1. A rotating shaft 110 is rotatably installed on the left side of the corresponding C-shaped fixing frame 102. A contact plate 111 is fixedly sleeved on the rotating shaft 110. An isosceles trapezoidal block 112 is fixedly installed on the left side of the vibration box 103, and the isosceles trapezoidal block 112 slides through the corresponding C-shaped fixing frame 102.

[0044] After the contact plate 111 leaves the isosceles trapezoidal block 112, the vibrating box 103 quickly returns to its original position under the elastic force of the limiting spring 105. As the rotating shaft 110 continues to rotate, the contact plate 111 continuously pushes the isosceles trapezoidal block 112, causing the vibrating box 103 to move continuously back and forth. The vibrating box 103 drives the inclined plate 106 to shake synchronously, so that the material falling on the inclined plate 106 is evenly distributed among several limiting plates 107 during the shaking process, and slides down the inclined surface of the inclined plate 106 onto the discharge plate 108. At the same time, the vibration... The box 103 also drives the discharge plate 108 to shake a second time, further improving the uniformity of material distribution. After two uniform dispersions, the material falls smoothly onto the discharge plate 109 under the shaking action of the discharge plate 108, and rolls down the inclined surface of the discharge plate 109 to the grinding area between the two grinding rollers 201. This structure effectively avoids the occurrence of grooves, local depressions or uneven wear on the surface of the grinding rollers 201 due to uneven material distribution, thereby ensuring that the material can be efficiently and uniformly ground into powder, improving grinding efficiency and product quality.

[0045] like Figure 5 As shown, grinding rollers 201 are fixedly sleeved on the two rotating rods 2 respectively. The corresponding rotating rod 2 passes through the grinding box 1, and the right end of the corresponding rotating rod 2 extends to the outside of the grinding box 1. A drive motor 202 is fixedly installed on the right side of the grinding box 1. The output shaft of the drive motor 202 is fixedly connected to the corresponding rotating rod 2. Synchronous gears 203 are fixedly sleeved on the two rotating rods 2 respectively, and the two synchronous gears 203 mesh with each other.

[0046] With the coordinated action of the two synchronous gears 203, the two grinding rollers 201 rotate synchronously, efficiently grinding the material falling between them.

[0047] like Figure 3 and Figure 7 As shown, a collection box 204 is fixedly installed inside the grinding box 1. Two grooved scrapers 205 are fixedly installed on the inner wall of the collection box 204. The tops of the two grooved scrapers 205 are in contact with the two grinding rollers 201 respectively. A conical grooved box 206 is fixedly installed on the bottom inner wall of the grinding box 1. Several circular grooves are opened on the bottom inner wall of the conical grooved box 206. A collection pipe is fixedly installed at the bottom of the grinding box 1. The several circular grooves are all connected to the collection pipe.

[0048] During the continuous rotation of the grinding roller 201, the grooved scraper 205 always maintains close contact with its surface, which can simultaneously scrape off the material cake and residual powder adhering to the surface of the grinding roller 201, effectively preventing fluctuations in the fineness of the finished product caused by uneven material layer or blockage, thereby ensuring the quality stability of cement products. The material after being crushed by the grinding roller 201 will fall into the collection box 204 below, and enter the conical grooved box 206 from the collection box 204.

[0049] like Figure 7 As shown, a round rod 207 is rotatably mounted through the conical grooved box 206. The round rod 207 rotatably passes through the collection pipe and is rotatably connected to the grinding box 1. A conical block 208 is fixedly sleeved on the round rod 207. Several agitators 209 are fixedly mounted on the outer wall of the conical block 208. The bottom ends of the agitators 209 are in contact with the bottom inner wall of the conical grooved box 206. Several arc-shaped inclined plates 210 are fixedly mounted on the inner wall of the conical grooved box 206. The arc-shaped inclined plates 210 are gradually lengthened from top to bottom.

[0050] The round rod 207 drives multiple agitators 209 mounted on it to rotate synchronously. The agitators 209 continuously crush and disperse the material inside the conical grooved box 206, fully decomposing the material cake formed by the extrusion of the grinding roller 201, so that the large particles and fine powder are separated. Under the rotation of the agitators 209.

[0051] like Figure 3 , Figure 4 and Figure 5 As shown, a discharge pipe 211 is fixedly installed inside the grinding box 1. An elevator 212 is set on the right side of the grinding box 1. The right end of the discharge pipe 211 extends into the elevator 212. A synchronizing rod 213 is rotatably installed through the support frame 101. Pulleys 214 are fixedly sleeved on the synchronizing rod 213, the corresponding rotating rod 2, and the rotating shaft 110, respectively. A synchronizing belt 215 is sleeved on several pulleys 214. A gear 1 216 is fixedly sleeved on the synchronizing rod 213. A gear 217 is fixedly sleeved on the round rod 207. Gear 1 216 and gear 2 217 mesh with each other.

[0052] When the particles collide or slide over the curved inclined plate 210, they will be lifted again due to the guiding effect of the inclined surface, and under the action of inertia, they will be thrown out from the inside of the conical grooved box 206 and enter the discharge pipe 211. Subsequently, these large particles that do not meet the fineness requirements enter the elevator 212 through the discharge pipe 211.

[0053] like Figure 4 and Figure 8 As shown, the feeding mechanism includes a feeding box 3 fixedly installed between two C-shaped fixed frames 102. A feeding pipe 301 is fixedly installed on the left side of the elevator 212. The end of the feeding pipe 301 extends into the feeding box 3. A triangular plate 302 is fixedly installed inside the feeding box 3. A rectangular hollow plate 303 is fixedly installed at the bottom of the triangular plate 302.

[0054] The powder is fed back to the feed box 3 via the feed pipe 301 to achieve circulating grinding, thereby effectively ensuring the consistency of the finished powder quality.

[0055] like Figure 8As shown, a return spring 304 is fixedly installed on the top inner wall of the rectangular hollow plate 303. A rectangular block 305 is fixedly installed at the bottom end of the return spring 304. The bottom end of the rectangular block 305 slides out to the outside of the triangular plate 302. A conical slider 306 is fixedly installed at the bottom end of the rectangular block 305. Several arc-shaped inclined grooves 307 are opened on the outer wall of the conical slider 306. The conical slider 306 is adapted to the outlet of the feed box 3.

[0056] As the conical slider 306 rises, part of its structure enters the feed box 3, causing the material in the feed box 3 to fall into the arc-shaped inclined groove 307. At the same time, the conical slider 306 will also drive the rectangular block 305 to rise together. At this time, the reset spring 304 is compressed and undergoes elastic deformation to store reset energy.

[0057] like Figure 8 As shown, an isosceles trapezoidal limiting block 308 is fixedly installed at the bottom of the conical slider 306, a fixing rod 309 is fixedly installed on the left inner wall of the grinding box 1, and a rectangular fixing block 310 is fixedly installed at the right end of the fixing rod 309. The rectangular fixing block 310 is adapted to the isosceles trapezoidal limiting block 308.

[0058] During the reciprocating movement of the vibration box 103, the fixed rod 309 will move synchronously. The fixed rod 309 will further drive the rectangular fixed block 310 to move. When the rectangular fixed block 310 contacts the inclined surface of the isosceles trapezoidal limiting block 308, the isosceles trapezoidal limiting block 308 will be pushed upward by the inclined surface, thereby driving the conical slider 306 to rise.

[0059] When the material is discharged from the feed box 3, it falls onto the inclined plate 106. At this time, the drive motor 202 is started, which drives the rotating rod 2 to rotate. The rotating rod 2, through the linkage of the pulley 214 and the synchronous belt 215, synchronously drives the rotating shaft 110 and the synchronous rod 213 to rotate. When the rotating shaft 110 rotates, it drives the contact plate 111 to rotate. When the contact plate 111 contacts the isosceles trapezoidal block 112, it uses its edge to cooperate with the inclined surface of the isosceles trapezoidal block 112 to push the isosceles trapezoidal block 112 towards the vibrating box 103, thereby causing the vibrating box 103 to move. At this time, the limiting spring 105 undergoes elastic deformation to absorb the impact and store the reset energy. When the contact plate 111 leaves the isosceles trapezoidal block 112, the limiting spring 105... Under the action of elasticity, the vibrating box 103 quickly resets. As the rotating shaft 110 continues to rotate, the contact plate 111 continuously pushes the isosceles trapezoidal block 112, causing the vibrating box 103 to move continuously back and forth. The vibrating box 103 drives the inclined plate 106 to shake synchronously, so that the material falling on the inclined plate 106 is evenly distributed between several limiting plates 107 during the shaking process, and slides down the inclined surface of the inclined plate 106 onto the discharge plate 108. At the same time, the vibrating box 103 will also drive the discharge plate 108 to shake a second time, further improving the uniformity of material distribution. After two even dispersions, the material falls smoothly onto the discharge plate 109 under the shaking action of the discharge plate 108, and rolls down the inclined surface of the discharge plate 109 into the grinding area between the two grinding rollers 201.

[0060] Under the coordinated action of the two synchronous gears 203, the two grinding rollers 201 rotate synchronously, efficiently grinding the material falling between them. During the continuous rotation of the grinding rollers 201, the grooved scraper 205 maintains close contact with their surface, simultaneously scraping away the material cake and residual powder adhering to the surface of the grinding rollers 201. This effectively prevents fluctuations in the fineness of the finished product due to uneven material layers or blockages, thus ensuring the quality stability of the cement product. The material after being crushed by the grinding rollers 201 falls into the lower collection box 204 and then enters the conical grooved box 206. Simultaneously, the synchronous rod 21... 3. During the rotation, the gear 216 is driven to rotate. The gear 216 drives the round rod 207 to rotate through meshing with the gear 217. The round rod 207 drives the multiple agitators 209 mounted on it to rotate synchronously. The agitators 209 continuously crush and disperse the material inside the conical grooved box 206, fully decomposing the material cake formed by the extrusion of the grinding roller 201, so that the large particles and fine powder are separated. Under the rotation of the agitators 209, the powder with smaller particle size will pass through the groove at the bottom of the conical grooved box 206, fall into the collection pipe below, and finally be discharged from the system.

[0061] During the rotation of the agitator 209, the resulting centrifugal force causes larger particles to rotate along the inclined inner wall of the conical grooved box 206. Larger particles are thrown higher by the centrifugal force and move upwards along the inner wall of the conical grooved box 206. When these larger particles come into contact with several curved inclined plates 210 during rotation, because the length of the curved inclined plates 210 closer to the top is shorter, the particles are lifted again by the guiding effect of the inclined surface when they collide with or slide past the curved inclined plates 210, and then, under the action of inertia, fall from the conical grooved box 206. 6. The material is thrown out from inside and enters the discharge pipe 211. Then, these large particles that do not meet the fineness requirements enter the elevator 212 through the discharge pipe 211 and are transported back to the feed box 3 through the feed pipe 301 to achieve circulating grinding, thereby effectively ensuring the quality consistency of the finished powder. In addition, during the process of the stirring frame 209 driving the larger particles to swing, since multiple arc-shaped inclined plates 210 are asymmetrically distributed and in different positions in the conical grooved box 206, various unqualified particles of different quality and particle size can be effectively thrown out of the conical grooved box 206.

[0062] During the reciprocating movement of the vibrating box 103, the fixed rod 309 moves synchronously. The fixed rod 309 further moves the rectangular fixed block 310. When the rectangular fixed block 310 contacts the inclined surface of the isosceles trapezoidal limiting block 308, the isosceles trapezoidal limiting block 308 is pushed upward by the inclined surface, thereby causing the conical slider 306 to rise. As the conical slider 306 rises, part of its structure enters the feed box 3, causing the material in the feed box 3 to fall into the arc-shaped inclined groove 307. At the same time, the conical slider 306 also drives the rectangular block 305. As they rise together, the return spring 304 is compressed and undergoes elastic deformation to store return energy. When the rectangular fixed block 310 leaves the isosceles trapezoidal limiting block 308, the conical slider 306 quickly resets and moves downward under the elastic force of the return spring 304, driving the arc-shaped inclined groove 307 to carry the material away from the feed box 3 and make the material slide down the arc-shaped inclined groove 307 onto the inclined plate 106. During the continuous reciprocating lifting and lowering process of the conical slider 306, not only is the quantitative control of the material in the feed box 3 achieved, but also the appropriate amount of material is ensured to enter the subsequent process each time.
