[0002] In the process of cement production, the uniform feeding of materials and the stable grinding are crucial for the quality control of the finished powder. At present, the commonly used grinding devices usually include a feeding structure, a vibration distribution structure, and a grinding roller rolling structure, but there are still many deficiencies in actual operation.

[0003] Traditional equipment lacks an effective dispersion and uniform cloth mechanism before the materials enter the grinding rollers, resulting in the materials being prone to concentrated falling, causing uneven stress between the grinding rollers; this uneven distribution not only affects the grinding efficiency, but also easily causes phenomena such as grooves, local depressions, or eccentric 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.

[0015] The present invention has the following beneficial effects: (1) For the powder grinding device for cement production of the present invention, when the material is discharged from the feed box, it will fall onto the inclined plate. At this time, the driving motor is started. The driving motor drives the rotating rod to rotate. Through the linkage of the synchronous belt and the belt pulley, the rotating shaft and the synchronous rod are synchronously driven to rotate. When the rotating shaft rotates, it drives the contact plate to rotate. When the contact plate contacts the isosceles trapezoidal block, by using the cooperation between its edge and the inclined surface of the isosceles trapezoidal block, the isosceles trapezoidal block is pushed to move towards the vibration box, thereby driving the vibration box to generate displacement. At this time, the limit spring undergoes elastic deformation to absorb the impact and store the reset energy. When the contact plate leaves the isosceles trapezoidal block, under the elastic force of the limit spring, the vibration box quickly resets. As the rotating shaft continues to rotate, the contact plate continuously pushes the isosceles trapezoidal block, enabling the vibration box to achieve continuous reciprocating movement. The vibration box drives the inclined plate to shake synchronously, so that the material falling on the inclined plate is evenly distributed between a plurality of limiting plates during the shaking process and slides down along the inclined surface of the inclined plate to the discharging plate. At the same time, the vibration box also drives the discharging plate to perform secondary shaking, further improving the uniformity of the material distribution. After two uniform dispersions, the material smoothly falls onto the discharging plate under the shaking action of the discharging plate and rolls along the inclined surface of the discharging plate to the grinding area between the two grinding rollers. This structure effectively avoids the phenomena of grooves, local depressions or eccentric wear on the surface of the grinding rollers caused by uneven material distribution, thereby ensuring that the material can be efficiently and evenly ground into powder, improving the powder grinding efficiency and the quality of the finished product; (2) In a pulverizing device for cement production according to the present invention, under the synergistic action of two synchronous gears, two grinding rollers rotate synchronously to efficiently grind the material falling therebetween. During the continuous rotation of the grinding rollers, the grooved scraper always keeps close contact with their surfaces, and can synchronously scrape off the cake and residual powder adhering to the surfaces of the grinding rollers, effectively preventing the fluctuation of the fineness of the finished product caused by uneven material layer or blockage, thereby ensuring the quality stability of the cement product. The material processed by the rolling of the grinding rollers will fall into the aggregate box below and enter the conical grooved box from the aggregate box. At the same time, during the rotation of the synchronous rod, the first gear is driven to rotate. The first gear further drives the round rod to rotate through the meshing transmission with the second gear. The round rod drives a plurality of stirring frames mounted thereon to rotate synchronously. The stirring frames continuously break and disperse the material inside the conical grooved box, fully decompose the cake formed by the extrusion of the grinding rollers, and separate the large particles and fine powders therein. Under the rotation of the stirring frames, the powders with smaller particle sizes will pass through the notches at the bottom of the conical grooved box, fall into the collecting pipe below, and finally be discharged from the system; while the larger particles are retained in the upper layer, realizing the effective classification of coarse and fine materials, not only improving the uniformity and discharging efficiency of the finished powder, but also realizing the timely separation of unqualified large particles, which is helpful for subsequent cyclic regrinding or separate treatment, thereby comprehensively improving the quality and production efficiency of the cement finished product; (3) In a pulverizing device for cement production according to the present invention, during the rotation of the stirring frames, the centrifugal force generated will drive the larger particles to perform a rotational movement along the inclined inner wall of the conical grooved box. The larger the mass of the particles, the higher they will be thrown under the action of the centrifugal force and move upward along the inner wall of the conical grooved box. When these larger particles contact a number of arc-shaped inclined plates during the rotation, since the length of the arc-shaped inclined plates closer to the upper part is shorter, when the particles impact or slide past the arc-shaped inclined plates, they will be lifted again due to the guiding action of the inclined surface and be thrown out of the conical grooved box internally under the action of inertia and enter the discharge pipe. Subsequently, these large particle materials that do not meet the fineness requirements enter the elevator through the discharge pipe and are re-transported to the feed box via the feed pipe to realize cyclic pulverizing, thereby effectively ensuring the quality consistency of the finished powder. In addition, during the process of the stirring frames driving the larger particles to swing, since a number of arc-shaped inclined plates are asymmetrically distributed and have different positions inside the conical grooved box, unqualified particles with various different masses and particle sizes can be effectively thrown out of the conical grooved box, further ensuring the complete separation between large particles and fine powders and improving the classification accuracy and the overall screening efficiency of the system; (4) In the process of the reciprocating movement of the vibration box of a grinding device for cement production according to the present invention, the fixed rod will be driven to move synchronously. The fixed rod further drives the rectangular fixed block to move. When the rectangular fixed block contacts the inclined surface of the isosceles trapezoidal limiting block, under the action of the inclined surface, the isosceles trapezoidal limiting block is pushed to slide upward, thereby driving the conical slider to rise. As the conical slider rises, a part of its structure enters the inside of the feed box, causing the material in the feed box to fall into the arc-shaped chute. At the same time, the conical slider will also drive the rectangular block to rise together. At this time, the reset spring is compressed and undergoes elastic deformation to store the reset energy. When the rectangular fixed block leaves the isosceles trapezoidal limiting block, under the elastic force of the reset spring, the conical slider quickly resets and moves downward, driving the arc-shaped chute to take the material away from the feed box and making the material slide along the arc-shaped chute onto the inclined plate. In the process of the continuous reciprocating lifting and lowering of the conical slider, not only the quantitative control of the material in the feed box is realized, ensuring that only an appropriate amount of material enters the subsequent process each time, but also the internal channel of the feed box is effectively dredged through its up and down movement, preventing material blockage and ensuring smooth feeding. After the material is evenly dispersed multiple times by the inclined plate and the discharge plate, it 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 the eccentric grinding phenomenon caused by uneven material distribution, thereby improving the operation stability of the equipment and the quality of the finished powder.

[0016] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-8 As shown, this invention is a grinding device for cement production, including a grinding powder box 1, and further including: A vibration mechanism, which is arranged inside the grinding powder box 1. The vibration mechanism includes a support frame 101 arranged at the bottom of the grinding powder box 1, and the vibration mechanism is used for evenly discharging materials during abrasive grinding; A separation mechanism, which is arranged inside the grinding powder box 1. The separation mechanism includes two rotating rods 2 arranged inside the grinding powder box 1, and the separation mechanism is used for separating unground granular materials from the crushed materials; A feeding mechanism, which is arranged above the grinding powder box 1. The feeding mechanism includes a feeding box 3 arranged on the upper part of the grinding powder box 1, and the feeding mechanism is used for controlling the release speed and release amount of materials.

[0022] Such as Figure 1 AndFigure 3 As shown in the figure, the vibration mechanism includes a support frame 101 fixedly installed at the bottom of the grinding box 1. Two U-shaped fixing frames 102 are fixedly installed on the grinding box 1. Above the grinding box 1, there is a vibration box 103. On one side where the two U-shaped fixing frames 102 are close to each other, telescopic rods 104 are respectively fixedly installed. One ends of the two telescopic rods 104 close to each other are fixedly connected to the vibration box 103. Limiting springs 105 are respectively sleeved on the two telescopic rods 104. One ends of the two limiting springs 105 away from each other are respectively fixedly connected to the two U-shaped fixing frames 102. One ends of the two limiting springs 105 close to each other are fixedly connected to the vibration box 103.

[0023] Push the isosceles trapezoidal block 112 to move towards the vibration box 103, thereby driving the vibration box 103 to generate displacement. At this time, the limiting spring 105 undergoes elastic deformation to absorb the impact and store the reset energy.

[0024] As Figure 3 shown in the figure, an inclined plate 106 is fixedly installed inside the vibration box 103. A number of limiting plates 107 are fixedly installed on the surface of the inclined plate 106. A material discharging plate 108 is fixedly installed on the inner wall of the vibration box 103. A discharging plate 109 is fixedly installed at the top of the grinding box 1. A rotating shaft 110 is rotatably installed on the left side of the corresponding U-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. The isosceles trapezoidal block 112 slides through the corresponding U-shaped fixing frame 102.

[0025] When the contact plate 111 leaves the isosceles trapezoidal block 112, under the elastic force of the limiting spring 105, the vibration box 103 quickly resets. As the rotating shaft 110 continues to rotate, the contact plate 111 continuously pushes the isosceles trapezoidal block 112, enabling the vibration box 103 to achieve continuous reciprocating movement. The vibration box 103 drives the inclined plate 106 to shake synchronously, causing the materials falling on the inclined plate 106 to be evenly distributed between a number of limiting plates 107 during the shaking process and slide down along the inclined surface of the inclined plate 106 to the material discharging plate 108. At the same time, the vibration box 103 also drives the material discharging plate 108 to perform secondary shaking, further improving the uniformity of material distribution. After two times of uniform dispersion, the materials smoothly fall onto the discharging plate 109 under the shaking action of the material discharging plate 108 and roll down along the inclined surface of the discharging plate 109 to the grinding area between the two grinding rollers 201. This structure effectively avoids the phenomena of grooves, local depressions or eccentric wear on the surface of the grinding rollers 201 caused by uneven material distribution, thereby ensuring that the materials can be efficiently and evenly ground into powder, improving the grinding efficiency and the quality of the finished product.

[0026] As Figure 5As shown, the vibration mechanism includes two rotating rods 2 rotatably installed in the grinding box 1. Grinding rollers 201 are fixedly sleeved on the two rotating rods 2 respectively. The corresponding rotating rod 2 penetrates through the grinding box 1, and the right end of the corresponding rotating rod 2 extends outside the grinding box 1. A driving motor 202 is fixedly installed on the right side of the grinding box 1. The output shaft of the driving 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 are meshed with each other.

[0027] Under the cooperative action of the two synchronous gears 203, the two grinding rollers 201 rotate synchronously to efficiently grind the material falling between them.

[0028] As Figure 3 and Figure 7 shown, a collecting box 204 is fixedly installed in the grinding box 1. Two grooved scrapers 205 are fixedly installed on the inner wall of the collecting box 204. The tops of the two grooved scrapers 205 are respectively in contact with the two grinding rollers 201. A conical grooved box 206 is fixedly installed on the bottom inner wall of the grinding box 1. A plurality of round grooves are opened on the bottom inner wall of the conical grooved box 206. A collecting pipe is fixedly installed at the bottom of the grinding box 1. The plurality of round grooves are all communicated with the collecting pipe.

[0029] During the continuous rotation of the grinding roller 201, the grooved scraper 205 always keeps in close contact with its surface, and can synchronously scrape off the cake and residual powder adhering to the surface of the grinding roller 201, effectively preventing the fluctuation of the finished product fineness caused by uneven material layer or blockage, thereby ensuring the quality stability of the cement product. The material after being rolled by the grinding roller 201 will fall into the lower collecting box 204 and enter the conical grooved box 206 from the collecting box 204.

[0030] As Figure 7 shown, a round rod 207 is rotatably installed through the conical grooved box 206. The round rod 207 rotatably penetrates through the collecting pipe, and the round rod 207 is rotationally connected to the grinding box 1. A conical block 208 is fixedly sleeved on the round rod 207. A plurality of stirring frames 209 are fixedly installed on the outer wall of the conical block 208. The bottoms of the plurality of stirring frames 209 are all in contact with the bottom inner wall of the conical grooved box 206. A plurality of arc-shaped inclined plates 210 are fixedly installed on the inner wall of the conical grooved box 206, and the plurality of arc-shaped inclined plates 210 are distributed in a gradually increasing length from top to bottom.

[0031] The round rod 207 drives the multiple stirring frames 209 installed thereon to rotate synchronously. The stirring frames 209 continuously break and disperse the material inside the conical grooved box 206, fully decompose the cake formed by the extrusion of the grinding roller 201, and separate the large particles and fine powders therein. Under the rotational action of the stirring frames 209.

[0032] As Figure 3 、 Figure 4 andFigure 5 As shown in the figure, a feeding pipe 211 is fixedly installed inside the powder grinding box 1. A hoist 212 is arranged on the right side of the powder grinding box 1. The right end of the feeding pipe 211 extends into the hoist 212. A synchronous rod 213 is rotatably installed through a support frame 101 inside the hoist 212. Synchronous belts 214 are fixedly sleeved on the synchronous rod 213, the corresponding rotating rods 2 and the rotating shafts 110 respectively. A pulley 215 is sleeved on a plurality of synchronous belts 214. A first gear 216 is fixedly sleeved on the synchronous rod 213. A second gear 217 is fixedly sleeved on the round rod 207. The first gear 216 meshes with the second gear 217.

[0033] When the particles impact or slide past the arc-shaped inclined plate 210, they will be lifted again due to the guiding effect of the inclined plane and are thrown out of the conical grooved box 206 under the action of inertia and enter the feeding pipe 211. Subsequently, these large particle materials that do not meet the fineness requirements enter the hoist 212 through the feeding pipe 211.

[0034] As Figure 4 and Figure 8 As shown in the figure, the feeding mechanism includes a feeding box 3 fixedly installed between two U-shaped fixing frames 102. A feeding pipe 301 is fixedly installed on the left side of the hoist 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.

[0035] It is retransported to the feeding box 3 via the feeding pipe 301 to realize cyclic powder grinding, thereby effectively ensuring the quality consistency of the finished powder.

[0036] As Figure 8 As shown in the figure, a return spring 304 is fixedly installed on the top inner wall of the rectangular hollow plate 303. The bottom end of the return spring 304 is fixedly installed with a rectangular block 305. The bottom end of the rectangular block 305 slides and extends outside the triangular plate 302. The bottom end of the rectangular block 305 is fixedly installed with a conical slider 306. A plurality of arc-shaped inclined grooves 307 are formed on the outer wall of the conical slider 306. The conical slider 306 is adapted to the outlet of the feeding box 3.

[0037] As the conical slider 306 rises, a part of its structure enters the inside of the feeding box 3, prompting the materials in the feeding box 3 to fall into the arc-shaped inclined grooves 307. At the same time, the conical slider 306 also drives the rectangular block 305 to rise together. At this time, the return spring 304 is compressed and undergoes elastic deformation to store return energy.

[0038] As Figure 8 As shown in the figure, an isosceles trapezoidal limit block 308 is fixedly installed at the bottom of the conical slider 306. A fixed rod 309 is fixedly installed on the left inner wall of the powder grinding box 1. The right end of the fixed rod 309 is fixedly installed with a rectangular fixed block 310. The rectangular fixed block 310 is adapted to the isosceles trapezoidal limit block 308.

[0039] During the reciprocating movement of the vibration box 103, the fixed rod 309 will be driven to move synchronously. The fixed rod 309 further drives the rectangular fixed block 310 to move. When the rectangular fixed block 310 contacts the inclined surface of the isosceles trapezoidal limit block 308, it pushes the isosceles trapezoidal limit block 308 to slide upward under the action of the inclined surface, thereby driving the conical slider 306 to rise.

[0040] When the material is discharged from the feed box 3, it will fall onto the inclined plate 106. At this time, the drive motor 202 is started. The drive motor 202 drives the rotating rod 2 to rotate. The rotating rod 2 synchronously drives the rotating shaft 110 and the synchronizing rod 213 to rotate through the linkage of the synchronous belt 214 and the pulley 215. 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, by using the cooperation between its edge and the inclined surface of the isosceles trapezoidal block 112, it pushes the isosceles trapezoidal block 112 to move towards the vibration box 103, thereby driving the vibration box 103 to generate a displacement. At this time, the limit 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, under the elastic force of the limit spring 105, the vibration box 103 quickly resets. As the rotating shaft 110 continues to rotate, the contact plate 111 continuously pushes the isosceles trapezoidal block 112, enabling the vibration box 103 to achieve continuous reciprocating movement. The vibration 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 limit plates 107 during the shaking process and slides down along the inclined surface of the inclined plate 106 to the discharge plate 108. At the same time, the vibration box 103 also drives the discharge plate 108 to perform a secondary shake, further improving the uniformity of the material distribution. After two uniform dispersions, the material steadily falls onto the discharge plate 109 under the shaking action of the discharge plate 108 and rolls down along the inclined surface of the discharge plate 109 to the grinding area between the two grinding rollers 201; Under the synergistic effect of two synchronous gears 203, two grinding rollers 201 achieve synchronous rotation, efficiently grinding the materials falling between them. During the continuous rotation of the grinding rollers 201, the grooved scraper 205 always maintains close contact with their surfaces, capable of synchronously scraping off the cake and residual powder adhering to the surfaces of the grinding rollers 201, effectively preventing fluctuations in the fineness of the finished product caused by uneven material layers or blockages, thereby ensuring the quality stability of cement products. The materials processed by the rolling of the grinding rollers 201 will fall into the lower aggregate box 204 and enter the conical grooved box 206 from the aggregate box 204. Meanwhile, during the rotation of the synchronous rod 213, it drives the first gear 216 to rotate. The first gear 216 further drives the round rod 207 to rotate through meshing transmission with the second gear 217. The round rod 207 drives a plurality of stirring frames 209 mounted on it to rotate synchronously. The stirring frames 209 continuously break and disperse the materials inside the conical grooved box 206, fully decomposing the cake formed by the extrusion of the grinding rollers 201, separating the large particles and fine powders therein. Under the rotational action of the stirring frames 209, the powders with smaller particle sizes will pass through the slots at the bottom of the conical grooved box 206, fall into the lower collecting pipe, and finally be discharged from the system; During the rotation of the stirring frames 209, the centrifugal force generated will drive the larger particles to perform a rotational motion along the inclined inner wall of the conical grooved box 206. The larger the mass of the particles, the higher they will be thrown under the action of the centrifugal force and move upward along the inner wall of the conical grooved box 206. When these larger particles come into contact with several arc-shaped inclined plates 210 during the rotation, since the length of the arc-shaped inclined plates 210 closer to the upper part is shorter, when the particles impact or slide past the arc-shaped inclined plates 210, they will be lifted again due to the guiding effect of the inclined surface and be thrown out of the inside of the conical grooved box 206 under the action of inertia and enter the discharge pipe 211. Subsequently, these large-particle materials that do not meet the fineness requirements enter the elevator 212 through the discharge pipe 211 and are re-transported to the feed box 3 via the feed pipe 301 to achieve cyclic grinding, thereby effectively ensuring the quality consistency of the finished powder. In addition, during the process of the stirring frames 209 driving the larger particles to swing, due to the asymmetric distribution and different positions of the several arc-shaped inclined plates 210 inside the conical grooved box 206, unqualified particles of various different qualities and particle sizes can be effectively thrown out of the outside of the conical grooved box 206; During the reciprocating movement of the vibration box 103, the fixed rod 309 will be driven to move synchronously. The fixed rod 309 further drives the rectangular fixed block 310 to move. When the rectangular fixed block 310 contacts the inclined surface of the isosceles trapezoidal limit block 308, it pushes the isosceles trapezoidal limit block 308 to slide upward under the action of the inclined surface, thereby driving 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 to rise together. At this time, the return spring 304 is compressed and undergoes elastic deformation to store the return energy. When the rectangular fixed block 310 leaves the isosceles trapezoidal limit block 308, under the elastic force of the return spring 304, the conical slider 306 quickly returns and moves downward, driving the arc-shaped inclined groove 307 to carry the material away from the feed box 3 and causing the material to slide down along the arc-shaped inclined groove 307 onto the inclined plate 106. During the continuous reciprocating lifting and lowering of the conical slider 306, not only is the quantitative control of the material in the feed box 3 realized, but also it is ensured that only an appropriate amount of material enters the subsequent process each time.
