Description

Technical Field

[0001] This utility model relates to the field of vertical mill technology, and in particular to a novel vertical mill with an adjustable number of working rollers. Background Technology

[0002] In industrial production, especially in sectors such as ore processing, cement manufacturing, and chemical raw material processing, vertical mills are widely used as important material grinding equipment due to their advantages such as high efficiency, energy saving, and small footprint. With increasingly diversified market demands, enterprises not only need to process materials with different properties but also need to flexibly adjust production efficiency and product precision according to order size, placing higher demands on the flexibility and adaptability of vertical mill equipment.

[0003] Existing vertical mill equipment has certain limitations in terms of the number of working rollers and the adjustment of grinding precision. On the one hand, most vertical mills have a fixed number of rollers, making it difficult to flexibly configure them to meet different material throughput and production needs. For example, when processing small batches of special materials, too many rollers not only waste energy but may also affect product characteristics due to over-grinding; while in large-scale production, a fixed number of rollers may lead to insufficient grinding efficiency. On the other hand, the number of rollers in traditional vertical mills is usually fixed during equipment manufacturing, making it difficult to quickly change according to actual production needs. When enterprises need to process small batches of special materials, too many rollers not only cause unnecessary energy consumption but may also affect the original properties of the materials due to over-grinding, limiting the enterprise's competitiveness in the high-end product market. To address this technical problem, this application proposes a novel vertical mill with an adjustable number of working rollers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel vertical mill with an adjustable number of working rollers. This mill allows for rapid adjustment of the number of working rollers as needed, improving grinding efficiency and reducing resource consumption. Simultaneously, by utilizing a pull rod-driven transmission assembly, the distance between the roller shaft and the grinding disc can be conveniently adjusted, enabling flexible control of grinding precision.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A novel vertical mill with an adjustable number of working rollers includes a motor and a reaction device. The drive end of the motor is fixedly connected to the upper side of the reaction device, and the rotating end of the motor is fixedly connected to a separator. The reaction device has a discharge port on the left side and a feed port on the right side. A door frame is fixedly connected to the lower side of the reaction device, and a sealing door is provided on the front side of the door frame. A fixing component is provided inside the sealing door. A fan is fixedly connected to the lower side of the reaction device, and a support is fixedly connected to the lower side of the reaction device. An outer sleeve is fixedly connected to the left side of the support, and a lifting component is provided inside the outer sleeve.

[0007] Furthermore, the lifting assembly includes a flat gear rotatably connected to the left side inside the outer casing, a second bevel gear fixedly connected to the right side of the flat gear, a first bevel gear meshing with the right side of the second bevel gear, and a stud fixedly connected to the upper side of the first bevel gear.

[0008] Furthermore, the fixing assembly includes a housing fixedly connected inside the sealed door, a screw threadedly connected inside the housing, a knob fixedly connected to the upper side of the screw, a fixed ball fixedly connected to the lower side of the screw, and a movable ball provided inside the housing.

[0009] Furthermore, an auxiliary block is provided inside the left side of the outer jacket, and a pull rod is fixedly connected inside the left side of the outer jacket, with the outer wall of the pull rod located on the front side of the auxiliary block.

[0010] Furthermore, a connecting post one is threadedly connected to the upper side of the stud, a connecting post two is rotatably connected to the upper side of the connecting post one, the outer wall of the connecting post two is rotatably connected to the inside of the sealing door, and a roller shaft is fixedly connected to the other end of the connecting post two.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 3 and Figure 4 One embodiment of this utility model is a novel vertical mill with an adjustable number of working rollers, comprising a motor 1 and a reaction device 5. The drive end of the motor 1 is fixedly connected to the upper side of the reaction device 5, and the rotating end of the motor 1 is fixedly connected to a separator 11. The reaction device 5 has a discharge port 2 on the left side and a feed port 3 on the right side. A door frame 13 is fixedly connected to the lower side of the reaction device 5. A sealing door 6 is provided on the front side of the door frame 13. A shell is provided inside the sealing door 6. A screw 22 is threadedly connected inside the shell. A knob 4 is fixedly connected to the upper side of the screw 22. A fixed ball 20 is fixedly connected to the lower side of the screw 22. A movable ball 21 is provided inside the shell. A fan 7 is fixedly connected to the lower side of the reaction device 5. A support 10 is fixedly connected to the lower side of the reaction device 5. An outer sleeve 8 is fixedly connected to the left side of the support 10. A spur gear 18 is installed inside the outer sleeve 8. A bevel gear 17 is fixedly connected to the right side of the spur gear 18. A bevel gear 16 is meshed with the right side of the bevel gear 17. A stud 15 is fixedly connected to the upper side of the bevel gear 16.

[0024] Specifically, during the use of the device, materials are put into the feeding port, ground by the rollers 12, and then rise under the action of the bottom fan 7. After being filtered by the separator 11, the finished product flows out from the discharge port 2. When using the device, different numbers of rollers 12 are often required to meet different materials and the needs of manufacturers. Therefore, two types of sealing doors 6 are designed. One type has a rotating ball on the upper side and a connecting column 2 14 inside, so that the rollers 12 can work. The other type is a sealing door 6 without a special function. The device has four door frames 13 inside, which can be used to replace different numbers of rollers 12 as needed, and the sealing doors 6 can be replaced easily. Rotating the knob 4 causes the screw 22 on the lower side to rotate inside the outer shell, which drives the fixed ball 20 to move downward. When the fixed ball 20 squeezes the movable ball 21, the movable ball 21 inside will move to the side and get stuck in the groove inside the feeding port 3. During this process, the self-locking property of the device's threads prevents the device from falling off. When release is needed, simply rotate knob 4 upwards. The internal space of the outer casing has a certain striped design to prevent the movable ball 21 from running around. When using roller 12, users may have different requirements for particle precision, so an adjustable angle design is designed. The lever can be pulled multiple times. During the rotation of the lever, it will drive the auxiliary block 19 to rotate as well. The auxiliary block 19 has two designs: a vertical plate on the front and an arc design on the rear. Therefore, during the downward pull, the vertical plate of the auxiliary block 19 will push the flat gear 18 to rotate. When the lever is pulled upwards, because of the arc design of the auxiliary block 19, the auxiliary block 19 will be pushed up, so the flat gear 18 will not rotate. Based on this principle, repeated rotation can achieve unidirectional rotation. Furthermore, when the lever is rotated upwards, the vertical plate design of the auxiliary block 19 can lock the flat gear 18. 8. To prevent the flat gear 18 from rotating, the flat gear 18 rotates, driving the bevel gear 17 to rotate. When the bevel gear 17 rotates, it drives the bevel gear 16 to rotate. When the bevel gear 16 rotates, it drives the stud 15 fixed on it. When the stud 15 rotates, the connecting column 9 threaded to it moves upward, thus achieving a lifting effect. When the connecting column 9 moves upward, the connecting column 14 rotating with it will rotate downward, thus making the roller 12 closer to the grinding disc, making the grinding more refined. Similarly, after rotating the auxiliary block 19, the pull rod is pulled in the opposite direction, which can lower the connecting column 9 and make the connecting column 14 rise, thus making the grinding particles slightly larger.

[0025] Reference Figure 2An auxiliary block 19 is located inside the left side of the outer casing 8, and a pull rod is fixedly connected to the inside of the left side of the outer casing 8. The outer wall of the pull rod is located on the front side of the auxiliary block 19. A vertical plate is located on the front side of the auxiliary block 19, and an arc plate is located on the rear side of the auxiliary block 19. A connecting post 1 9 is threadedly connected to the upper side of the stud 15, and a connecting post 2 14 is rotatably connected to the upper side of the connecting post 1 9. The outer wall of the connecting post 2 14 is rotatably connected to the inside of the sealing door 6, and a roller 12 is fixedly connected to the other end of the connecting post 2 14. A groove is provided inside the door frame 13, and the outer wall of the movable ball 21 is located below the fixed ball 20. A hole is opened on the lower side of the outer casing, and the outer wall of the movable ball 21 is located inside the hole.

[0026] Specifically, in this embodiment, the material is fed into the inlet 3, ground by the rollers 12, and rises to the separator 11 for screening under the action of the fan 7. Qualified finished products are discharged from the outlet 2. To flexibly adapt to different material characteristics and production needs, two types of sealing door 6 designs are retained, and the number of door frames 13 remains four, facilitating the replacement of the number of rollers 12 as needed. For the installation and fixing of the sealing door 6, rotating the knob 4 causes the screw 22 to rotate under the constraint of the limit slide rail, driving the fixed ball 20 to move down along the guide rod, squeezing the movable ball 21 so that it is locked into the groove of the inlet 3. The threaded self-locking achieves a stable fixation, and rotating the knob 4 in the opposite direction allows for disassembly. To adjust the grinding precision of the roller 12, pull the lever to drive the auxiliary block 19. Utilizing the special structure of its front vertical plate and rear arc plate, the flat gear 18 is driven to rotate in one direction. Through the transmission of bevel gear 17 and bevel gear 16, the stud 15 is rotated, which in turn drives the connecting column 9 to move up and down. This controls the rotation angle of the connecting column 14, thereby adjusting the distance between the roller 12 and the grinding disc to meet different grinding precision requirements.

[0027] Working Principle: The bottom of the reaction device 5 has four door frames 13. Each door frame 13 can be equipped with two types of sealing doors 6. One type is a working roller door with an internal connecting column 2 14 connected to the roller shaft 12, used for material grinding; the other type is a sealing door 6 without special structure, used only for enclosed spaces. By rotating the knob 4, the screw 22 drives the fixed ball 20 to squeeze the movable ball 21, making it lock into the groove of the door frame 13; rotating in the opposite direction allows for disassembly, facilitating adjustment of the number of working rollers according to production needs. Pulling the lever on the left side of the outer sleeve 8 drives the auxiliary block 19 to rotate. The front vertical plate of the auxiliary block 19 pushes the flat gear 18 to rotate clockwise, while the rear arc plate allows it to rotate counterclockwise, achieving unidirectional adjustment. The flat gear 18 drives the bevel gear 2 17, bevel gear 1 16, and screw 15 to rotate, causing the connecting column 1 9 to move up and down, thereby changing the tilt angle of the connecting column 2 14, adjusting the distance between the roller shaft 12 and the grinding disc, and achieving grinding accuracy adjustment.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
