Description
Technical Field
[0001] This utility model relates to the field of cement clinker production technology, and in particular to a cement clinker production apparatus. Background Technology
[0002] Cement clinker is one of the basic raw materials for cement production. It is mainly made from limestone, clay and other minerals through high-temperature calcination. Cement clinker is usually in granular or block form, and is gray or dark gray in color. Its main components include calcium silicate, calcium aluminate and calcium aluminoferrite. These components have an important influence on the strength, durability and hardening performance of cement. Cement is an important material for modern construction and infrastructure. Its production process mainly includes raw material pretreatment, calcination and grinding. As the core component of cement production, the quality of cement clinker directly affects the performance and use effect of cement. Therefore, a cement clinker production device is needed.
[0003] In the production of cement clinker, the clinker needs to be crushed. Traditional cement clinker production equipment usually adopts a single crushing method. This method is often difficult to crush the clinker to the ideal particle size. Because larger particles are not effectively crushed, the final product may still contain large-sized cement clinker particles, affecting the uniformity and strength of the cement. In addition, traditional cement clinker production equipment generates a large amount of dust and particulate matter when processing clinker. These particles are difficult to control effectively during the production process. Since there is usually no dust removal equipment, the dust released during the production process will spread everywhere, causing environmental pollution and seriously affecting the surrounding air quality. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cement clinker production device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cement clinker production device includes a rectangular box with a circular box extending through its top and an open bottom. A feed hopper is fixed to the top of the circular box and communicates with it. A crushing mechanism for crushing cement clinker is installed inside the circular box. A circular perforated plate is fixed to the inner side wall of the circular box, and a grinding mechanism for grinding cement clinker is installed on the top of the perforated plate. A dust removal mechanism is installed on the outer side wall of the rectangular box. A collection box is extending through the outer side wall of one end of the rectangular box near the bottom. During operation, the crushing mechanism performs initial crushing of the cement clinker, followed by secondary crushing by the grinding mechanism. This process breaks the cement clinker to an ideal particle size, improving the uniformity and strength of the cement and preventing large, uncrushed particles from affecting the final product quality. The dust removal mechanism effectively controls dust generated during production, preventing environmental pollution and improving workplace air quality.
[0006] As a further embodiment of this utility model, the crushing mechanism includes two first rotating shafts, both of which are rotatably connected to the inner wall of the feed hopper, and one end of each of the two first rotating shafts extends through the outside of one end of the feed hopper. Crushing rollers are sleeved on the outer walls of both first rotating shafts, and the two crushing rollers are arranged in parallel. Gears are sleeved on one end of each of the two first rotating shafts, and the two gears mesh. A first motor is fixed to the outer wall of the other end of the rectangular box, and the output shaft of the first motor is fixed to the other end of one of the first rotating shafts via a coupling. A protective cover is fixed to the outer wall of one end of the feed hopper, and the two gears are located inside the protective cover. The first motor drives one of the first rotating shafts to rotate, which in turn drives the other first rotating shaft to rotate, thereby causing the two crushing rollers to rotate in a counter-rotating manner, thus enabling the crushing of cement clinker.
[0007] As a further embodiment of this utility model, the grinding mechanism includes a second rotating shaft, which is rotatably connected to the top center of a circular perforated plate. Two connecting rods are symmetrically fixed to the outer wall of the second rotating shaft, and a rolling roller is rotatably sleeved on the outer wall of each of the two connecting rods. Two brushes are symmetrically fixed to the outer walls of the two second rotating shafts, and the two brushes and the two rolling rollers are vertically distributed. A second motor is fixed to the bottom of the circular perforated plate, and the output shaft of the second motor is fixed to the second rotating shaft through a coupling. The second motor drives the second rotating shaft to rotate, which in turn drives the two rolling rollers to rotate and grind the clinker falling on the top of the circular perforated plate. This can crush the clinker to the ideal particle size, avoid the appearance of large uncrushed particles, and improve the uniformity and strength of the cement.
[0008] As a further embodiment of this utility model, the dust removal mechanism includes a dust collection box, which is fixed to the outer wall of a rectangular box. A lid is provided on the top of the dust collection box, and a U-shaped plate is fixed to the bottom of the lid, adapting to the dust collection box. Columns are fixed at the four corners of the bottom of the U-shaped plate. A locking mechanism for engaging the lid is provided at the four corners of the outer wall of the dust collection box. A connecting cylinder is fixed to the inner wall of the rectangular box, and multiple air inlets are fixed to the outer wall of the connecting cylinder, all communicating with the connecting cylinder. A flexible hose is provided through the top of the lid, communicating with the connecting cylinder. A suction device is fixed to the outer wall of the dust collection box. The system includes a vacuum pump, with its air inlet connected to a dust collection box. A dustproof net is slidably connected to the inner wall of the dust collection box. A U-shaped seat is located on the inner wall of the dust collection box, above the vacuum pump. Lifting mechanisms for raising the vacuum pump are located at the four corners of the bottom of the U-shaped seat. The vacuum pump is driven to evacuate the dust collection box, creating a negative pressure environment inside the dust collection box. This negative pressure environment then creates a negative pressure environment inside the connecting cylinder. Dust generated at this time enters the connecting cylinder through multiple air inlets and is sucked into the dust collection box through a hose. The dust inside the dust collection box falls onto the top of the dustproof net and is collected, effectively preventing environmental pollution.
[0009] As a further embodiment of this utility model, the snap-fit mechanism includes a first sleeve, which is fixed to the outer wall of the dust collector. A first circular plate is slidably connected to the inner wall of the first sleeve. A limiting rod is fixed to one end of the first circular plate, and one end of the limiting rod passes through the inner wall of the dust collector. A through hole is provided on the outer wall of the cover near one of the corners, and the through hole is adapted to the limiting rod. A pull rod is fixed to the other end of the first circular plate, and one end of the pull rod passes through the outside of the other end of the first sleeve. A first spring is sleeved on the side wall of the pull rod. Pulling the four pull rods causes the four first circular plates to move away from each other along the inner walls of the four first sleeves until the four limiting rods enter the interior of the four first sleeves. At this time, the four limiting rods are disengaged from the four through holes, so that the cover can be removed from the top of the dust collector.
[0010] As a further embodiment of this utility model, the lifting mechanism includes a second sleeve, which is fixed at one corner of the bottom of the dust collector. A second circular plate is slidably connected inside the second sleeve, and a connecting column is fixed to the top of the second circular plate, with the top end of the connecting column penetrating the top of the second sleeve. The connecting column and the U-shaped seat are fixed together. A second spring is installed inside the second sleeve, located below the second circular plate. Since columns are fixed at the four corners of the bottom of the U-shaped plate, when the lid is placed on top of the dust collector, the four columns will squeeze the dustproof net, causing the U-shaped seat to move along the inside of the dust collector. As the sidewall moves downwards and the U-shaped seat moves downwards, the four connecting columns drive the four second circular plates to move downwards along the inner sidewalls of the four second sleeves, thereby compressing the four second springs. Once the cover is removed from the top of the dust collector, the four columns no longer compress the dust screen, meaning the U-shaped seat is no longer under force. At this point, under the reaction force of the four compressed second springs, the four second circular plates are pushed to move in the opposite direction, which, together with the four connecting columns, drives the U-shaped seat to move upwards along the inside of the dust collector, thus pushing the dust screen to the top of the dust collector for easy cleaning of the dust on top of the dust screen.
[0011] The beneficial effects of this utility model are as follows: 1. During use, this device performs primary crushing of cement clinker through a crushing mechanism, and secondary crushing of the crushed clinker through a grinding mechanism. This process can crush the cement clinker to the ideal particle size, thereby improving the uniformity and strength of the cement and avoiding the impact of large particles that are not effectively crushed on the final product quality.
[0012] 2. Through the design of the dust removal mechanism, the dust generated during the production process can be effectively controlled, environmental pollution can be avoided, and the air quality in the workplace can be improved.
[0013] 3. The cover can be quickly removed from the top of the dust collector using the snap-fit mechanism. Combined with the lifting mechanism, the dust filter can be lifted to the top of the dust collector, making it convenient to clean the dust on top of the dust filter. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figure 1 - Figure 9A cement clinker production device includes a rectangular box 1, with a circular box 2 extending through the top of the rectangular box 1 and an open bottom. A feed hopper 3 is fixed to the top of the circular box 2 and is connected to the circular box 2. A crushing mechanism for crushing cement clinker is installed inside the circular box 2. A circular perforated plate 15 is fixed to the inner side wall of the circular box 2, and a grinding mechanism for grinding cement clinker is installed on the top of the circular perforated plate 15. A dust removal mechanism for dust removal is installed on the outer side wall of the rectangular box 1. A collection box 14 extends through the outer side wall of one end of the rectangular box 1 near the bottom. During use, the device performs primary crushing of cement clinker through the crushing mechanism and secondary crushing through the grinding mechanism. This process can crush cement clinker to the ideal particle size, thereby improving the uniformity and strength of cement and preventing large particles that are not effectively crushed from affecting the final product quality. The dust removal mechanism effectively controls the dust generated during production, avoids environmental pollution, and improves the air quality in the workplace.
[0018] In this embodiment, the crushing mechanism includes two first rotating shafts 10, both of which are rotatably connected to the inner wall of the feed hopper 3, and one end of each of the two first rotating shafts 10 extends through the outside of one end of the feed hopper 3. Crushing rollers 11 are sleeved on the outer walls of both first rotating shafts 10, and the two crushing rollers 11 are arranged in parallel. Gears 12 are sleeved on one end of each of the two first rotating shafts 10, and the two gears 12 mesh. A first motor 9 is fixed to the outer wall of the other end of the rectangular box 1, and the output shaft of the first motor 9 is fixed to the other end of one of the first rotating shafts 10 via a coupling. A protective cover 13 is fixed to the outer wall of one end of the feed hopper 3, and the two gears 12 are located inside the protective cover 13. The first motor 9 drives one of the first rotating shafts 10 to rotate, and the two gears 12 drive the other first rotating shaft 10 to rotate, thereby causing the two crushing rollers 11 to rotate in a counter-rotating manner, thus crushing cement clinker.
[0019] In this embodiment, the grinding mechanism includes a second rotating shaft 20, which is rotatably connected to the top center of the circular perforated plate 15. Two connecting rods 22 are symmetrically fixed to the outer wall of the second rotating shaft 20, and a rolling roller 16 is rotatably sleeved on the outer wall of each of the two connecting rods 22. Two brushes 17 are symmetrically fixed to the outer walls of the two second rotating shafts 20, and the two brushes 17 and the two rolling rollers 16 are vertically distributed. A second motor 21 is fixed to the bottom of the circular perforated plate 15, and the output shaft of the second motor 21 is fixed to the second rotating shaft 20 through a coupling. The second motor 21 drives the second rotating shaft 20 to rotate, which in turn drives the two rolling rollers 16 to rotate and grind the clinker falling on the top of the circular perforated plate 15. This can crush the clinker to the ideal particle size, avoid the appearance of large uncrushed particles, and improve the uniformity and strength of the cement.
[0020] In this embodiment, the dust removal mechanism includes a dust collection box 4, which is fixed to the outer wall of a rectangular box 1. A box cover 5 is provided on the top of the dust collection box 4, and a U-shaped plate 23 is fixed to the bottom of the box cover 5, adapting to the dust collection box 4. Columns 25 are fixed at the four corners of the bottom of the U-shaped plate 23. A locking mechanism for locking the box cover 5 is provided at the four corners of the outer wall of the dust collection box 4. A connecting cylinder 18 is fixed to the inner wall of the rectangular box 1, and multiple air inlets 19 are fixed to the outer wall of the connecting cylinder 18, all communicating with the connecting cylinder 18. A flexible hose 6 is provided through the top of the box cover 5, communicating with the connecting cylinder 18. An exhaust fan 7 is fixed to the outer wall of the dust collection box 4. The air inlet is connected to the dust collection box 4. A dustproof net 26 is slidably connected to the inner wall of the dust collection box 4. A U-shaped seat 27 is provided on the inner wall of the dust collection box 4, and the U-shaped seat 27 is located above the air extractor 7. Lifting mechanisms for lifting the air extractor 7 are provided at the four corners of the bottom of the U-shaped seat 27. The air extractor 7 is driven to perform air extraction treatment inside the dust collection box 4, so that the inside of the dust collection box 4 is a negative pressure environment, which in turn makes the inside of the connecting cylinder 18 a negative pressure environment. At this time, the generated dust enters the inside of the connecting cylinder 18 through multiple air inlets 19 and is sucked into the inside of the dust collection box 4 through the hose 6. The dust that enters the inside of the dust collection box 4 falls on the top of the dustproof net 26 and is collected, which can effectively avoid environmental pollution.
[0021] In this embodiment, the snap-fit mechanism includes a first sleeve 8, which is fixed to the outer wall of the dust collector 4. A first circular plate 32 is slidably connected to the inner wall of the first sleeve 8. A limiting rod 33 is fixed to one end of the first circular plate 32, and one end of the limiting rod 33 passes through the inner wall of the dust collector 4. A through hole 24 is provided on the outer wall of the cover 5 near one of the corners, and the through hole 24 is adapted to the limiting rod 33. A pull rod 34 is fixed to the other end of the first circular plate 32, and one end of the pull rod 34 passes through the outside of the other end of the first sleeve 8. A first spring 35 is sleeved on the side wall of the pull rod 34. Pulling the four pull rods 34 causes the four first circular plates 32 to move away from each other along the inner walls of the four first sleeves 8 until the four limiting rods 33 enter the interior of the four first sleeves 8. At this time, the four limiting rods 33 are disengaged from the four through holes 24, so that the cover 5 can be removed from the top of the dust collector 4.
[0022] In this embodiment, the lifting mechanism includes a second sleeve 28, which is fixed at one corner of the bottom of the dust collector 4. A second circular plate 29 is slidably connected inside the second sleeve 28. A connecting column 31 is fixed to the top of the second circular plate 29, and the top of the connecting column 31 passes through the top of the second sleeve 28. The connecting column 31 and the U-shaped seat 27 are fixed. A second spring 30 is provided inside the second sleeve 28, and the second spring 30 is located below the second circular plate 29. Since columns 25 are fixed at the four corners of the bottom of the U-shaped plate 23, when the cover 5 is placed on top of the dust collector 4, the four columns 25 will squeeze the dustproof net 26, causing the U-shaped seat 27 to move downward along the inner wall of the dust collector 4. As the rotary seat 27 moves downward, it works in conjunction with the four connecting columns 31 to drive the four second circular plates 29 downward along the inner walls of the four second sleeves 28, thereby compressing the four second springs 30. Once the cover 5 is removed from the top of the dust collector 4, the four columns 25 no longer press the dustproof net 26, meaning the rotary seat 27 is no longer under force. At this time, under the reaction force of the four compressed second springs 30, the four second circular plates 29 are pushed to move in the opposite direction, and together with the four connecting columns 31, the rotary seat 27 moves upward along the inside of the dust collector 4, thereby pushing the dustproof net 26 to the top of the dust collector 4, making it convenient to clean the dust on the top of the dustproof net 26.
[0023] Working Principle: During operation, cement clinker is placed into the feed hopper 3, and the power switch of the first motor 9 is turned on. The first motor 9 drives one of the first rotating shafts 10 to rotate, which in turn drives the other first rotating shaft 10 to rotate. This, in turn, drives the two crushing rollers 11 to rotate in opposite directions, thus crushing the cement clinker. The crushed cement clinker falls into the circular perforated plate 15. Then, the power switch of the second motor 21 is turned on, driving the second rotating shaft 20 to rotate. This, in turn, drives the two grinding rollers 16 to rotate, grinding the clinker that has fallen onto the top of the circular perforated plate 15. Simultaneously, the rotation of the second rotating shaft 20 drives the two brushes 17 to rotate, further grinding the cement clinker. The clinker is cleaned by sweeping it from the top of the circular perforated plate 15 into the collection box 14 for collection. This crushes the clinker to the ideal particle size, avoiding large uncrushed particles and improving the uniformity and strength of the cement. In addition, while crushing the cement clinker, the power switch of the exhaust fan 7 is turned on to drive the exhaust fan 7 to evacuate the dust collection box 4, creating a negative pressure environment inside the dust collection box 4. This, in turn, creates a negative pressure environment inside the connecting cylinder 18. At this time, the generated dust enters the connecting cylinder 18 through multiple air inlets 19 and is sucked into the dust collection box 4 through the hose 6. The dust inside the dust collection box 4 falls on the top of the dustproof net 26 and is collected, which can effectively prevent environmental pollution. When it is necessary to clean the dust on the top of the dustproof net 26, pull the four levers 34 so that the four first circular plates 32 move away from each other along the inner walls of the four first sleeves 8 until the four limiting rods 33 enter the interior of the four first sleeves 8. At this time, the four limiting rods 33 are disengaged from the four through holes 24, so that the box cover 5 can be removed from the top of the dust collector 4. Since the bottom corners of the U-shaped plate 23 are fixed with columns 25, when the box cover 5 is placed on the top of the dust collector 4, the four columns 25 will squeeze the dustproof net 26, causing the U-shaped seat 27 to move downward along the inner wall of the dust collector 4. The downward movement of the U-shaped seat 27 is the same as... At this time, the four connecting columns 31 respectively drive the four second circular plates 29 to move downward along the inner sidewalls of the four second sleeves 28, thereby compressing the four second springs 30. Once the box cover 5 is removed from the top of the dust collector 4, the four columns 25 no longer squeeze the dustproof net 26, that is, the U-shaped seat 27 is no longer under force. At this time, under the reaction force of the four compressed second springs 30, the four second circular plates 29 are pushed to move in the opposite direction, and the four connecting columns 31 drive the U-shaped seat 27 to move upward along the inside of the dust collector 4, thereby pushing the dustproof net 26 to the top of the dust collector 4, which facilitates the cleaning of the dust on the top of the dustproof net 26.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
