Description

Technical Field

[0001] The invention relates to the technical field of powder classifiers, in particular to a powder classifier with a breaking structure. Background Art

[0002] In cement production, grinding systems are mainly divided into two types: open circuit and closed circuit. Since closed circuit grinding systems are easier to control product fineness, change product varieties, and have stronger adaptability to the market, closed circuit grinding systems have been widely used. As an important supporting equipment in closed circuit grinding systems, powder selectors do not have the function of crushing materials, but their performance directly affects the operating status of the system, that is, the grinding efficiency, output and energy consumption of the system.

[0003] According to the search, the Chinese patent document, announcement number: CN118237267A, discloses an adjustable V-type powder classifier and an adjustment method. By providing a baffle in the fine material discharge channel of the powder classifier, the accuracy of the powder classifier is improved without increasing energy consumption. At the same time, an adjustment device for the baffle is provided, and the position of the baffle can be adjusted according to different production needs, thereby adjusting the classification efficiency of the V-type powder classifier.

[0004] However, in actual use, the V-type powder classifier can only affect the speed of fine powder discharge by adjusting the height and angle of the baffle plate, but cannot adjust the direction and speed of the powder selection airflow, that is, it cannot change the time that the material stays in the powder selection area, making it difficult to adjust the classification particle size.

[0035] See also Figure 1-Figure 8 A powder classifier with a disintegrating structure comprises a feeding shell 1, an air supply shell 2 and an air outlet shell 3, one side of the feeding shell 1 is connected to the air supply shell 2 by bolts, and the other side of the feeding shell 1 is connected to the air outlet shell 3 by bolts, a disintegrating component 4 and an air guide component 5 are rotatably connected inside the feeding shell 1, an execution component 6 is installed on the back of the feeding shell 1, one end of the disintegrating component 4 is fixedly connected to a No. 1 worm gear 7, which is transmission-connected to a No. 1 worm 8, one end of the air guide component 5 is fixedly connected to a No. 2 worm gear 9, which is transmission-connected to a No. 2 worm 10, the inside of the No. 1 worm 8 is fixedly connected to a No. 1 transmission rod 11, and the inside of the No. 2 worm 10 is fixedly connected to a No. 2 transmission rod 12;

[0036] The actuator assembly 6 includes two gear box bodies 61 and a guide rail 68 fixedly connected to the back of the unloading shell 1, wherein one of the gear box bodies 61 is internally rotatably connected with bevel gear 1 62 and bevel gear 2 63, and the other gear box body 61 is internally rotatably connected with bevel gear 3 64 and bevel gear 4 65, bevel gear 2 63 is fixedly connected to face gear 1 66 through an axis, and bevel gear 3 64 is fixedly connected to face gear 2 67 through an axis, the outer surface of the guide rail 68 is slidably connected to a slide seat 69, a dual-axis motor 610 is installed in the slide seat 69, one output shaft of the dual-axis motor 610 is fixedly connected to face gear 3 611, and the other output shaft of the dual-axis motor 610 is fixedly connected to face gear 4 612, one side of the slide seat 69 is fixedly connected to an ear block 613, and the outer surface of the ear block 613 is connected to the output end of the cylinder 614.

[0037] Furthermore, the material discharging shell 1 includes a feed hopper 101 arranged at the top, at least two inclined plates 102 are connected to the inside of the feed hopper 101 by bolts, and a coarse material discharge hopper 103 is arranged at the bottom of the material discharging shell 1. The advantage is that the material after cement grinding is transported to the feed hopper 101 by an elevator or other feeding equipment, and when the material vertically enters the feed hopper 101, it will first fall on the inclined plate 102. Since the material has a certain gravity impact on the inclined plate 102, it will be initially scattered, which can reduce the lumps and agglomeration in the material. After the material enters the inside of the material discharging shell 1, the scattered material can better contact with the wind force, and achieve a better classification effect.

[0038] Furthermore, a plurality of wind guide components 5 are provided, and the wind guide components 5 include a wind guide rotating rod 51 , and a wind guide grille plate 52 is mounted on the outer surface of the wind guide rotating rod 51 by bolts.

[0039] Furthermore, a plurality of scattering assemblies 4 are provided, and the scattering assemblies 4 include a scattering rotating rod 41 , and a scattering grid plate 42 is connected to the outer surface of the scattering rotating rod 41 by bolts. The advantage is that when the material falls into the interior of the discharge shell 1 after preliminary scattering, the material will fall on multiple scattering grid plates 42 in sequence during this process. The scattering grid plates 42 can further scatter the material. The scattering grid plates 42 break up the agglomerated materials into smaller particles through mechanical blocking and impact, ensuring that the material enters the subsequent powder selection link in a relatively uniform state. After the air flow is introduced into the interior of the discharge shell 1, the material becomes more dispersed after passing through the scattering grid plates 42, so that the material can fully contact with the air flow. The air flow plays a role in carrying and sorting the material during the powder selection process. The larger contact area helps to improve the sorting effect of the air flow on the material, so that materials of different particle sizes can be separated more effectively; and the air guide grid plates 52 can guide the direction of the air flow to ensure that the air flow can flow along the designed path, so as to better interact with the material. The scattering grid plates 42 are connected to the scattering rotating rod 41 by bolts, so that they can be easily disassembled and replaced. Similarly, the air guide grid plates 52 are also connected to the air guide rotating rod 51 by bolts, which is also convenient for disassembly and replacement.

[0040] Furthermore, the cylinder 614 is installed on the back of the blanking shell 1 by bolts, the bevel gear 1 62 and the bevel gear 2 63 are meshed and connected with each other, the bevel gear 3 64 and the bevel gear 4 65 are meshed and connected with each other, one end of the No. 1 transmission rod 11 is fixedly connected to the bevel gear 1 62, and one end of the No. 2 transmission rod 12 is fixedly connected to the bevel gear 4 65. The advantage is that when the cylinder 614 is started, its output end drives the ear block 613 to move, and the ear block 613 drives the slide 69 to move on the guide rail 68, so that the dual-axis motor 610 can be displaced, and then can drive the face gear 3 611 and the face gear 4 612 to move, so that the face gear 3 611 can mesh with the face gear 1 66, so that when the dual-axis motor 610 is started, the face gear 1 66 can be rotated, and then the bevel gear 2 63 is driven to rotate, and the bevel gear 2 63 drives the bevel gear 1 62 to rotate , the bevel gear 1 62 drives the No. 1 transmission rod 11 to rotate, the No. 1 transmission rod 11 drives the No. 1 worm 8 to rotate, the No. 1 worm 8 can drive the No. 1 worm wheel 7 to rotate, the No. 1 worm wheel 7 drives the scattering rotating rod 41 to rotate, so that the angle position of the scattering grid plate 42 can be adjusted. Similarly, when the face gear 4 612 is meshed with the face gear 2 67, the face gear 2 67 drives the bevel gear 3 64 to rotate, the bevel gear 3 64 drives the bevel gear 4 65 to rotate, the bevel gear 4 65 drives the No. 2 transmission rod 12 to rotate, and the No. 2 transmission rod 12 The second worm 10 is driven to rotate, the second worm 10 drives the second worm wheel 9 to rotate, and the second worm wheel 9 drives the air guide rod 51 to rotate, so that the angle position of the air guide grid plate 52 can be adjusted. By changing the angle position of the air guide grid plate 52, the cross-sectional area through which the airflow passes can be adjusted, thereby affecting the airflow speed. When a higher airflow speed is required to sort materials of a specific particle size, the angle can be appropriately adjusted to reduce the cross-sectional area and increase the airflow speed; conversely, the cross-sectional area can be increased to reduce the airflow speed, so as to achieve the best sorting effect for materials of different particle sizes; by adjusting the angle position of the scattering grid plate 42, materials with different characteristics can be optimized. For example, for harder materials, the angle can be appropriately increased to increase the collision force and improve the scattering effect; for materials with greater viscosity, the angle can be adjusted to make the materials stay longer on the scattering grid plate 42 so as to be better scattered; by finely adjusting the angles of the scattering grid plate 42 and the air guide grid plate 52, the purpose of adjusting the powder selection particle size can be achieved.

[0041] Furthermore, the slide 69 includes four rollers 691 disposed on the inner wall, and the rollers 691 are in rolling contact with the guide rail 68. The advantage is that when the cylinder 614 drives the ear block 613 to move and drives the slide 69 to move, the four rollers 691 can slide on the guide rail 68, which can reduce the resistance when the slide 69 moves.

[0042] Furthermore, the air supply housing 2 includes a main air inlet 201 arranged at the top and a secondary air inlet 202 arranged at the bottom, and both the main air inlet 201 and the secondary air inlet 202 are connected to hot air.

[0043] Furthermore, an air outlet 301 is provided on the top of the air outlet housing 3 , and a plurality of triangular brackets 13 are welded to the outer surfaces of the air outlet housing 3 and the air supply housing 2 . The advantage is that after the hot air enters from the main air inlet 201, a strong airflow is formed. This airflow can fully disperse and suspend the materials entering the discharge shell 1, avoiding material accumulation, so that the materials can collide and contact with the scattering grid plate 42. Materials of different particle sizes are subjected to different forces in the hot air, and finer particles are easily carried upward by the hot air, so that the fine materials can be discharged from the air outlet 301, while the coarse materials continue to move downward under the action of gravity and air flow resistance, and are finally discharged from the coarse material discharge hopper 103. In this way, the material is classified. At the same time, the heat in the hot air can dry the material to prevent it from adhering to the scattering grid plate 42 and the air guide grid plate 52. By introducing hot air into the secondary air inlet 202, hot air can be introduced in the direction close to the bottom of the discharge shell 1, thereby further classifying the materials, so that the finer materials can continue to rise from the bottom of the discharge shell 1 under the action of the hot air and be discharged from the air outlet 301.

[0044] Furthermore, a sampling door 14 is installed on the front of the air outlet housing 3, the sampling door 14 is connected to the air outlet housing 3 by a hinge, and one side of the sampling door 14 is fixedly connected to a locking plate 141. The advantage is that the fine material entering the air outlet housing 3 can be sampled by opening the sampling door 14, so that the particle size of the fine material can be detected, and further adjustments can be made according to the particle size of the fine material sorted out.

[0045] Furthermore, a rectangular hole is formed through the outer surface of the locking plate 141, a connecting plate 15 and a fixing plate 16 are welded to the front of the air outlet housing 3, a through hole is formed through the outer surface of the connecting plate 15, a locking rod 17 is inserted into the through hole, a spring 18 is sleeved on the outer surface of the locking rod 17, one end of the spring 18 abuts against the fixing plate 16, and the locking rod 17 is inserted into the fixing plate 16, and a pull ring 19 is fixedly connected to the bottom end of the locking rod 17. The advantage is that when the pull ring 19 is pulled downward, the locking rod 17 can be driven to move downward, so that the locking rod 17 can be separated from the through hole of the connecting plate 15, and then the sampling door 14 can be opened conveniently. When the sampling is completed and the sampling door 14 is closed, the connecting plate 15 is inserted into the rectangular hole of the locking plate 141, and by loosening the pull ring 19, the locking rod 17 can be automatically inserted into the through hole of the connecting plate 15 under the action of the spring 18, so that the sampling door 14 is conveniently locked.

[0046] When in use, the cement ground material is first transported to the feed hopper 101 through an elevator or other feeding equipment. When the material vertically enters the feed hopper 101, it will first fall on the inclined plate 102 and be initially scattered to reduce the lumps and agglomerations in the material. The hot air is connected to the main air inlet 201 and the secondary air inlet 202, and the air guide grid plate 52 is set to guide the air flow path. The material entering the discharge shell 1 contacts the scattering grid plate 42 and is further scattered. The material is fully in contact with the airflow. The airflow plays a role in carrying and sorting the material during the powder selection process. The materials of different particle sizes are subjected to different forces in the hot air, which is relatively Fine particles are easily carried upward by hot air, so that the fine material can be discharged from the air outlet 301, while the coarse material continues to move downward under the action of gravity and airflow resistance, and is finally discharged from the coarse material discharge hopper 103. The fine material entering the air outlet shell 3 can be sampled by opening the sampling door 14, and then the fine material can be detected and analyzed. If the particle size of the fine material does not meet the requirements, the angle position of the air guide grid plate 52 and the scattering grid plate 42 can be adjusted by the execution component 6. In this way, the flow path of the hot air inside the discharge shell 1 can be changed, and it can be optimized for materials with different characteristics to achieve the purpose of adjusting the powder selection particle size.
