Description

Technical Field

[0001] The present invention relates to the technical field of raw material crushing and grinding, and particularly to a raw material crushing and grinding device for ceramic production. Background Art

[0002] Ceramics is a general term for pottery and porcelain, and it is also a kind of arts and crafts in our country. As far back as the Neolithic Age, there were already rough and simple painted pottery and black pottery in our country. Pottery and porcelain have different textures and properties. Pottery is mainly made of clay with relatively high viscosity and strong plasticity. It is opaque, has fine pores and weak water absorption, and makes a dull sound when struck. Porcelain is made of clay, feldspar and quartz. It is translucent, water-insoluble, corrosion-resistant, with a hard and dense body, and makes a crisp sound when tapped. The traditional ceramic arts and crafts in our country are of high quality and beautiful shape, with high artistic value and are famous all over the world.

[0003] After a large amount of retrieval, it is found that the prior art publication number is CN109317279B, which discloses a raw material crushing and grinding device for ceramic production, including a chassis, a control box, a power cord, a frame, a first electric push rod, a movable frame, a first motor, a machine head, a grinding tool, a grinding disc, a storage battery, a jet device, a support seat, a pushing mechanism and a rotating mechanism. The left and right ends of the control box are installed on the front side surface of the right end of the chassis by screws, the power cord is plugged into the right side of the rear end of the chassis, and the bottom of the frame is fixed to the left and right ends of the chassis by rivets. When changing materials, the second electric push rod works to drive the connecting plate to slide on the slide rail, and at the same time drives the support seat to slide, so that the grinding disc moves out from the bottom of the grinding tool, changing the deficiency that the original staff needed to drill into the bottom of the front end of the frame to change materials, increasing the speed of changing materials, improving work efficiency, and improving safety.

[0004] After the above-mentioned existing ceramic raw material crushing and grinding device is crushed, when the air classifier pulverizes the ground raw materials for secondary classification, the ground raw materials are transferred to the air classifier through the air flow. The crushing device provided in the air classifier can block the larger raw materials. However, after a long time, the raw materials that are just the right size stuck in the crushing device will block the crushing device in the air classifier, resulting in damage to the air classifier.

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.

[0035] Please refer to Figures 1 to 8, A raw material crushing and grinding device for ceramic production, including a mounting base 1. A crushing cylinder 101 is fixedly installed at the upper end of the mounting base 1. A plurality of intake pipes 102 are arrayedly installed at the lower end of the crushing cylinder 101, and the air inlet and outlet of the intake pipe 102 face the bottom end of the crushing cylinder 101. A dust-proof cover 306 is provided at the air outlet of the intake pipe 102 to prevent the crushed dust in the crushing cylinder 101 from being discharged from the crushing cylinder 101 through the intake pipe 102. An inlet mechanism 2 for transferring raw materials is provided at the lower end of the crushing cylinder 101. A crushing mechanism 3 for successively crushing raw materials of different sizes from bottom to top is provided in the crushing cylinder 101. An air flow crushing mechanism 4 for secondary crushing and separation of the crushed raw materials is provided at the upper end of the crushing cylinder 101. Specifically, the air flow crushing mechanism 4 selects and crushes the raw material dust carried by the upward air flow, and at the same time prevents the air flow crushing mechanism 4 from being blocked.

[0036] Please refer to Figures 1 - 2 , The inlet mechanism 2 includes a feed cylinder 201, and the feed cylinder 201 is fixedly installed on the side end of the crushing cylinder 101. A transfer pipe 202 is fixedly installed at the lower end of the feed cylinder 201. A drive motor 203 is fixedly installed on the side end of the transfer pipe 202. A transfer rod 204 is fixedly installed at the output end of the drive motor 203. A screw blade 205 is fixedly welded on the outer wall of the transfer rod 204. Specifically, when raw materials need to be added to the crushing cylinder 101, the raw materials are placed in the hopper, the drive motor 203 is started, and the screw blade 205 transfers the raw materials into the crushing cylinder 101 for crushing. A baffle 206 is rotatably arranged at one end of the transfer pipe 202 away from the drive motor 203. The screw blade 205 and the baffle 206 prevent the splashing raw materials from splashing into the transfer pipe 202 and then being discharged from the feed cylinder 201 through the transfer pipe 202.

[0037] Please refer to Figures 1 - 4 , The crushing mechanism 3 includes a crushing motor 301, and the crushing motor 301 is fixedly installed on the side end of the feed cylinder 201. A drive gear 302 is fixedly installed at the output end of the crushing motor 301. The drive gear 302 is meshed with a drive rack 303. Both the above drive gear 302 and drive rack 303 are in the shape of a crown gear, and the drive rack 303 passes through the side end of the crushing cylinder 101. A mounting frame 304 is fixedly installed on the inner wall of the crushing cylinder 101 close to the drive rack 303.

[0038] Please refer to Figures 1 - 4, a rotating gear 305 is fixedly installed at the upper end of the mounting frame 304, and a dust-proof cover 306 is fixedly installed at the upper end of the mounting frame 304 near the rotating gear 305. The dust-proof cover 306 prevents raw material dust from entering the gear meshing part, resulting in gear damage. The rotating gear 305 meshes with the driving rack 303. A lifting cylinder 307 is fixedly installed at the lower end of the rotating gear 305, a lifting rod 308 is fixedly installed at the lower end of the lifting cylinder 307, and a crushing frame 309 is fixedly installed at the lower end of the lifting rod 308. Specifically, when the crushing motor 301 is started, the driving rack 303 drives the transmission gear to rotate, so that the rotating gear 305 drives the crushing frame 309 to start rotating.

[0039] Please refer to Figures 1 - 4 , a rotating disk 310 is fixedly installed at the upper end of the rotating gear 305, a rotating rod is fixedly installed at the upper end of the rotating disk 310, a moving rod 311 is rotatably sleeved on the outer wall of the rotating rod. A pressure cylinder 312 is fixedly installed at the upper end of the mounting frame 304 near the moving rod 311. Hydraulic oil is provided in the pressure cylinder 312. A piston rod 313 is movably installed in the pressure cylinder 312. One end of the moving rod 311 away from the rotating rod is rotatably installed at one end of the piston rod 313 away from the pressure cylinder 312. A pressure transmission pipe 314 is fixedly installed at one end of the pressure cylinder 312 away from the piston rod 313, and one end of the pressure transmission pipe 314 away from the pressure cylinder 312 is fixedly installed at the input end of the lifting cylinder 307. Specifically, when the rotating gear 305 rotates and the rotating disk 310 rotates, the rotating rod drives the moving rod 311 to start moving, so that the piston rod 313 starts to reciprocate, and the hydraulic oil in the pressure cylinder 312 is transmitted to the lifting cylinder 307 through the pressure transmission pipe 314, so that the lifting cylinder 307 pushes the lifting rod 308 to start reciprocating up and down, so that the crushing frame 309 reciprocates up and down to crush the raw materials in the crushing cylinder 101.

[0040] Please refer to Figures 1 - 6, a protective ring 315 is fixedly installed near the upper end of the mounting bracket 304 on the crushing frame 309. A grinding ring 316 is fixedly installed on the outer wall of the protective ring 315. A grinding cylinder 317 is rotatably installed near the lower end of the grinding ring 316 on the crushing frame 309, and the grinding cylinder 317 is arranged in an elliptical shape that fits the lower arc of the crushing cylinder 101. A grinding ball 318 is fixedly installed at the lower end of the crushing frame 309, and the diameter of the grinding ball 318 is one-half of the diameter of the lower semi-circle of the crushing cylinder 101. The lower end of the grinding ball 318 is provided with grooves in a "V" shape in an array. When the ground raw materials are squeezed by the grinding ball 318 again, the pressure on the ground raw materials is greater when passing through the smallest part of the "V"-shaped grooves, and the ground raw materials are squeezed to the largest part of the "V"-shaped grooves. At the same time, the air inlet pipe 102 intakes air, so as to transfer the ground raw materials to the position of the grinding cylinder 317 for secondary grinding. The upward airflow in the crushing cylinder 101 carries the ground raw materials to the grinding ring 316 for grinding, so that the grinding size is controlled within a suitable range.

[0041] Please refer to Figures 1 - 8 , the airflow crushing mechanism 4 includes an air pump 401, and the air pump 401 is fixedly installed at the upper end of the crushing cylinder 101. A feeding cover 402 is rotatably installed near the suction end of the air pump 401 on the crushing cylinder 101. The feeding cover 402 is provided with a plurality of material-passing vacancies 403. Specifically, when the air pump 401 is started, the air pump 401 starts to suck air, and the feeding cover 402 starts to suck air, so that the air inlet pipe 102 starts to intake air. The upward airflow carries the ground raw material dust to the material-passing vacancies 403 provided in the feeding cover 402. The raw material dust of a suitable size passes through the material-passing vacancies 403. A movable block 404 for scraping the particles stuck on the material-passing vacancies 403 is slidably arranged on the inner wall of the material-passing vacancies 403. The movable block 404 provided in the material-passing vacancies 403 prevents raw materials from getting stuck in the material-passing vacancies 403, resulting in blockage of the material-passing vacancies 403.

[0042] Please refer to Figures 1 - 8 It should be noted that there seems to be an inaccuracy in the description of the "V"-shaped groove in the original text. It is described as an "eight"-shaped groove in Chinese, which is translated as a "V"-shaped groove here for the sake of logical consistency. If this is not in line with the actual situation, please adjust it according to the correct content., a rotating ring 405 is fixedly installed at the upper end of the feeding cover 402. A crushing ring 406 is rotatably installed on the inner wall of the rotating ring 405, and the crushing ring 406 is attached to the inner wall of the feeding cover 402. Driven gear rings 407 are fixedly installed at the upper ends of both the feeding cover 402 and the crushing ring 406, and a driving gear 408 is meshed between the driven gear rings 407. A rotating motor 409 is fixedly installed at the upper end of the driving gear 408, and the rotating motor 409 is fixedly installed at the upper end of the crushing cylinder 101. When the rotating motor 409 is started, the driving gear 408 rotates, causing the two driven gear rings 407 to rotate in opposite directions, so that the rotating ring 405 and the feeding cover 402 rotate relative to each other. The crushing ring 406 is provided with crushing grooves 410 with a width equal to half of the width of the material passing gap 403. The crushing grooves 410 block the raw materials that have not reached the appropriate size through the material passing gap 403. The output end of the air pump 401 is fixedly installed with an exhaust pipe 411. Specifically, when the upward airflow in the upward crushing cylinder 101 carries the ground raw materials to the space between the crushing ring 406 and the feeding cover 402, the feeding cover 402 and the crushing ring 406 rotate relative to each other, so that the raw materials are crushed into an appropriate dust size. The end of the exhaust pipe 411 away from the air pump 401 is fixedly installed with a separator 412, and the above-mentioned separator 412 is a prior art and will not be elaborated here. The output end of the separator 412 is fixedly installed with a discharge valve 413. Specifically, when gas-solid separation of the crushed raw materials is required, the raw material powder is separated in the separator 412 through the air transmission, so that the powder is separated from the air, and the air is discharged from the separator 412.

[0043] Please refer to Figures 1 - 8 , linkage blocks 414 are fixedly installed at both the upper and lower ends of the movable block 404. Linkage ropes 415 are fixedly installed at the ends of the linkage blocks 414 away from the movable block 404. Control blocks 416 are fixedly sleeved on the outer walls of the linkage ropes 415. Control grooves 417 are opened on the inner wall of the rotating ring 405 close to the control blocks 416, and the control blocks 416 are slidably installed in the control grooves 417. Specifically, when the feeding cover 402 rotates, the linkage ropes 415 drive the control blocks 416 to slide in the control grooves 417, so as to clean the raw materials stuck in the material passing gap 403 and prevent the material passing gap 403 from being blocked.

[0044] Please refer to Figures 1 - 8, a telescopic rope 418 is fixedly installed between the control groove 417 and the control block 416. After the telescopic rope 418 moves the control block 416 to a suitable position, the telescopic rope 418 drives the control block 416 to move back to its original position. A limiting block 419 is slidably installed at the upper end of the control block 416, and a limiting rod 420 is slidably arranged at the lower end of the limiting block 419. A pushing block 421 is fixedly installed on the inner wall of the feeding cover 402 close to the limiting rod 420. A control hole is opened at the position of the control block 416 close to the limiting rod 420. A retracting rod 422 is fixedly installed on the inner wall of the control groove 417 close to the limiting block 419, and a pushing rod 423 is fixedly installed on the inner wall of the control groove 417 away from the retracting rod 422. Specifically, when the feeding cover 402 rotates to make the pushing block 421 push the limiting block 419 to rotate, the control block 416 moves. When the control block 416 moves to the position of the retracting rod 422, the retracting rod 422 is inserted into the control block 416, so that the limiting rod 420 no longer blocks the limiting block 419, and the pushing block 421 no longer pushes the limiting rod 420 to rotate. The telescopic rope 418 pulls the control block 416 to move to the position of the retracting rod 422, and the retraction pushes the limiting rod 420 to move. The limiting rod 420 pushes the limiting block 419 to rise, and so on, so that the linkage rope 415 drives the movable block 404 to move up and down, thus avoiding the blockage of the material passing gap 403.

[0045] The working principle of the present invention is as follows: When it is necessary to crush ceramic raw materials, the raw materials are placed in the feeding cylinder 201, the driving motor 203 is started, and the transmission rod 204 drives the auger blade 205 to start rotating. The auger blade 205 rotates to transfer the raw materials in the feeding cylinder 201 to the crushing cylinder 101. The crushing motor 301 is started, and the driving gear 302 drives the driving rack 303 to start rotating. The crushing frame 309 starts to rotate. When the crushing frame 309 starts to rotate, the rotating disk 310 starts to rotate, and the rotating rod drives the moving rod 311 to start moving, so that the piston rod 313 starts to reciprocate. The hydraulic oil in the pressurizing cylinder 312 is transmitted to the lifting cylinder 307 through the pressure transmission pipe 314, so that the lifting cylinder 307 pushes the lifting rod 308 to start reciprocating up and down, so that the crushing frame 309 reciprocates up and down to crush the raw materials in the crushing cylinder 101, so as to crush the raw materials more completely;

[0046] When the crushing motor 301 is started, the air pump 401 is started, so that the intake pipe 102 starts to intake air, and the feeding cover 402 starts to inhale. The upward airflow carries the ground raw material dust and transfers it to the material passing gap 403 provided in the feeding cover 402. The rotating motor 409 is started, and the rotating ring 405 rotates with the feeding cover 402 to crush the raw materials to a suitable dust size, so as to make the dust grinding more delicate;

[0047] When the feeding cover 402 rotates to make the pushing block 421 push the limiting block 419 to rotate, the control block 416 moves. When the control block 416 moves to the position of the retractable rod 422, the retractable rod 422 is inserted into the control block 416, so that the limiting rod 420 no longer blocks the limiting block 419, and the pushing block 421 no longer pushes the limiting rod 420 to rotate. The retractable rope 418 pulls the control block 416 to move to the position of the retractable rod 422, and the retractable rod 422 pushes the limiting rod 420 to move. The limiting rod 420 pushes the limiting block 419 to rise, and so on, so that the linkage rope 415 drives the movable block 404 to move up and down, thereby avoiding the blockage of the material passing gap 403.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
