Description

Technical Field

[0001] This utility model relates to the field of sinter production technology, and in particular to a vibrating screen for blast furnace sinter production. Background Technology

[0002] Sintered ore is a blocky iron-containing raw material with a certain particle size and strength formed by mixing iron ore powder, fuel, flux and other raw materials in a certain proportion, after batching, mixing and granulation, and then heating it in sintering equipment by ignition. The fuel in the raw materials burns and generates high temperature, causing the ore powder particles to undergo bonding, softening and melting reactions. Finally, it is cooled to form a blocky iron-containing raw material with a certain particle size and strength. It is one of the main raw materials for blast furnace ironmaking.

[0003] In existing technologies, when sintered ore needs to be put into use, it needs to be graded and screened by a vibrating screen to separate sintered ore of different particle sizes, remove large impurities and ensure that the sintered ore meets the particle size requirements of blast furnace smelting, thereby improving smelting efficiency and sintered ore utilization. However, during the screening process of sintered ore, the lack of uniform feeding method of vibrating screen leads to uneven distribution of material on the screen surface, sometimes accumulating and clogging and sometimes sparse and interrupted material, which can easily affect screening efficiency and classification accuracy, and also aggravate screen wear due to uneven force.

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a vibrating screen for blast furnace sintering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vibrating screen for blast furnace sintering ore, comprising a feeding mechanism, wherein an anti-jamming mechanism is provided on the bottom side of the feeding mechanism, the feeding mechanism comprising a vibrating screen body, a support arm provided at one end of the vibrating screen body, one end of the vibrating screen body being fixedly connected to one end of the support arm, a cylinder rod II provided on the inner surface of the other end of the support arm, the inner surface of the other end of the support arm being fixedly connected to the outer side of the bottom end of the cylinder rod II, a fixing plate provided at the top end of the cylinder rod II, the top end of the cylinder rod II being rotatably connected to the bottom end of the fixing plate, a feeding plate provided at the top end of the fixing plate, the top end of the fixing plate being fixedly connected to the bottom side of one end of the feeding plate, an inclined plate provided on the inner surface of the feeding plate, the inner surface of the feeding plate contacting the bottom side of the inclined plate.

[0006] In a preferred embodiment, the anti-jamming mechanism includes a semi-circular disc, a rubber hammer is provided at the edge of the semi-circular disc, one end of the rubber hammer is fixedly connected to the edge of the semi-circular disc, and a strike plate is provided at the other end of the rubber hammer, with the other end of the rubber hammer in contact with one side of the bottom end of the strike plate.

[0007] In a preferred embodiment, the top of the impact plate is fixedly connected to the bottom side of the feeding plate, a motor is provided at the center of the semi-circular disk, the output end of the motor is fixedly connected to the center of the semi-circular disk, and the outer side of the motor is fixedly connected to one side of the support arm.

[0008] In a preferred embodiment, the inner wall of the feeding plate is provided with a rotating component, the inner wall of the feeding plate is rotatably connected to the upper and lower ends of the rotating component, and the inner wall of the rotating component is fixedly connected to the outer side of the inclined plate.

[0009] In a preferred embodiment, a movable rod is provided at a recessed end of the inclined plate, and the recessed end of the inclined plate is rotatably connected to one side of the movable rod. A connecting plate is provided on the other side of the movable rod, and the other side of the movable rod is fixedly connected to one end of the connecting plate.

[0010] In a preferred embodiment, a cylinder rod is provided at the middle end of the connecting plate, and the middle end of the connecting plate is fixedly connected to one end of the cylinder rod. The top side of the cylinder rod is fixedly connected to the bottom side of the feeding plate.

[0011] In a preferred embodiment, one end of the feeding plate is provided with a side rod, one end of the feeding plate is rotatably connected to the top end of the side rod, the bottom end of the side rod is provided with a feed inlet, and the bottom end of the side rod is fixedly connected to the top edge of the feed inlet.

[0012] In a preferred embodiment, the bottom end of the feed inlet is fixedly connected to the top side of one end of the vibrating screen body.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. When cylinder rod one is extended, it will drive the connecting plate to move synchronously, and then push the two sets of inclined plates through the two movable rods respectively, so that the four inclined plates in each set will deflect at an angle around their corresponding rotating parts. Since the two sets of inclined plates are staggered, the guide gap of the feeding plate and the shape of the conveying channel will be changed during the deflection process. Secondly, by extending cylinder rod two, the tilt angle of the feeding plate is increased, which speeds up the flow of material along the feeding plate towards the feed inlet. Thus, the material is conveyed in a reasonable way in two different ways, realizing dynamic control of the material flow rate entering the vibrating screen body. 2. The motor rotates 90 degrees back and forth, causing the semi-disc to run in the same way. A rubber hammer is fixed at the edge of the semi-disc. As the semi-disc rotates, the rubber hammer will come into contact with the impact plate, thereby generating a periodic impact force on the impact plate. This causes the material to vibrate during the conveying process, effectively preventing excessive friction between material particles from accumulating and clogging on the feeding plate.

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. Example

[0020] like Figure 1-4As shown, this utility model provides a technical solution: a vibrating screen for blast furnace sintering ore, including a feeding mechanism 1, an anti-jamming mechanism 2 provided on the bottom side of the feeding mechanism 1, the feeding mechanism 1 including a vibrating screen body 11, a support arm 19 provided at one end of the vibrating screen body 11, one end of the vibrating screen body 11 being fixedly connected to one end of the support arm 19, a cylinder rod 110 provided on the inner surface of the other end of the support arm 19, the inner surface of the other end of the support arm 19 being fixedly connected to the outer side of the bottom end of the cylinder rod 110, a fixing plate 111 provided at the top end of the cylinder rod 110, the top end of the cylinder rod 110 being rotatably connected to the bottom end of the fixing plate 111, a feeding plate 13 provided at the top end of the fixing plate 111, the top end of the fixing plate 111 being fixedly connected to the bottom side of one end of the feeding plate 13, an inclined plate 15 provided on the inner surface of the feeding plate 13, the inner surface of the feeding plate 13 contacting the bottom side of the inclined plate 15, and a rotating component provided on the inner wall of the feeding plate 13. 14. The inner wall of the feeding plate 13 is rotatably connected to the upper and lower ends of the rotating part 14. The inner wall of the rotating part 14 is fixedly connected to the outer side of the inclined plate 15. A movable rod 16 is provided at the recessed part of one end of the inclined plate 15. The recessed part of one end of the inclined plate 15 is rotatably connected to one side of the movable rod 16. A connecting plate 17 is provided on the other side of the movable rod 16. The other side of the movable rod 16 is fixedly connected to one end of the connecting plate 17. A cylinder rod 18 is provided at the middle end of the connecting plate 17. The middle end of the connecting plate 17 is fixedly connected to one end of the cylinder rod 18. The top side of the cylinder rod 18 is fixedly connected to the bottom side of the feeding plate 13. One end of the feeding plate 13 is provided with a side rod 112. One end of the feeding plate 13 is rotatably connected to the top end of the side rod 112. The bottom end of the side rod 112 is provided with a feed inlet 12. The bottom end of the side rod 112 is fixedly connected to the top edge of the feed inlet 12. The bottom end of the feed inlet 12 is fixedly connected to the top side of one end of the vibrating screen body 11.

[0021] In this embodiment, when the vibrating screen for blast furnace sintered ore is in use, a feed inlet 12 is installed at one end of the vibrating screen body 11. The material flows into the interior of the vibrating screen body 11 through the feed inlet 12. A side plate is fixed at the edge of the feed inlet 12. The top of the side plate is rotatably connected to one end of the feeding plate 13. The feeding plate 13 is inclined and concave, so it has two sides. Four rotating parts 14 are installed on each side. The inner walls of the four rotating parts 14 are all penetrated by inclined plates 15. Since the rotating parts 14 on both sides are not in the same radial direction, the inclined plates 15 have an interlaced effect. Therefore, there are eight inclined plates 15, arranged in groups of four. There is a movable rod 16 in the concave part of one end of each group of inclined plates 15. 16 is connected to one end of the four inclined plates 15 by a movable part, so there are two movable rods 16. One side of the two movable rods 16 is connected to the connecting plate 17. The middle end of the connecting plate 17 is designed with a cylinder rod 18. Therefore, when the cylinder rod 18 is retracted or extended, it will drive the connecting plate 17 to move synchronously. Then, the two movable rods 16 will push the two sets of inclined plates 15 respectively, so that the four inclined plates 15 in each set will deflect at an angle around their corresponding rotating parts 14. Since the two sets of inclined plates 15 are staggered, their deflection process will change the guide gap and conveying channel shape of the feeding plate 13, thereby adjusting the speed and distribution of the material flow to the feed inlet 12, and realizing dynamic control of the material flow rate entering the vibrating screen body 11. A support arm 19 is installed at one end of the vibrating screen body 11. There are two support arms 19, and each support arm 19 has a cylinder rod 110 installed at one end. The top end of the cylinder rod 110 is rotatably connected to the bottom end of the fixed plate 111 via a movable part. The top end of the fixed plate 111 is fixed to the bottom side of one end of the feeding plate 13. Since the other end of the feeding plate 13 is fixed to the port of the feed inlet 12 via a side rod 112, the extension of the cylinder rod 110 will push the fixed plate 111 to rotate upward, thereby driving the feeding. The angle of the feeding plate 13 changes around the connection point between the side rod 112 and the feed inlet 12, increasing the tilt angle of the feeding plate 13 and accelerating the flow of material along the feeding plate 13 towards the feed inlet 12. Conversely, if the cylinder rod 110 retracts, it will pull the fixed plate 111 to rotate downward, causing the feeding plate 13 to flip downward to reduce the tilt angle, thereby slowing down the material conveying speed and realizing the adjustment of the overall tilt angle of the feeding plate 13. This further coordinates with the action of the inclined plate 15 to optimize the feeding efficiency of material entering the vibrating screen body 11. Example

[0022] like Figure 1-4As shown, the anti-jamming mechanism 2 includes a semi-circular disk 21, a rubber hammer 22 is provided at the edge of the semi-circular disk 21, one end of the rubber hammer 22 is fixedly connected to the edge of the semi-circular disk 21, a receiving plate 23 is provided at the other end of the rubber hammer 22, the other end of the rubber hammer 22 is in contact with one side of the bottom end of the receiving plate 23, the top end of the receiving plate 23 is fixedly connected to the bottom side of the feeding plate 13, a motor 24 is provided at the center of the semi-circular disk 21, the output end of the motor 24 is fixedly connected to the center of the semi-circular disk 21, and the outer side of the motor 24 is fixedly connected to one side end of the support arm 19.

[0023] In this embodiment, a receiving plate 23 is installed on the bottom side of one end of the feeding plate 13, and a motor 24 is fixed to one side of the support arm 19. The output end of the motor 24 is connected to a semi-circular disk 21. The reciprocating rotation of the motor 24 at ninety degrees causes the semi-circular disk 21 to rotate in the same manner. A rubber hammer 22 is fixed at the edge of the semi-circular disk 21. As the rubber hammer 22 rotates with the semi-circular disk 21, it contacts the receiving plate 23, thereby generating a periodic impact force on the receiving plate 23, which promotes the material conveying... The vibration generated during the process effectively prevents excessive friction between material particles from accumulating and clogging on the feeding plate 13, ensuring that it can flow smoothly to the feed inlet 12 and enter the vibrating screen body 11. Finally, when the rubber hammer 22 contacts the impact plate 23, it will make contact with the bottom end of the impact plate 23. This method allows the impact plate 23 to follow the angle change of the feeding plate 13, and the impact plate 23 will be raised to a certain height. After the height is raised, the rubber hammer 22 will contact the bottom side of the impact plate 23, thereby avoiding ineffective striking.

[0024] Working principle: like Figure 1-4 As shown, when cylinder rod 18 is retracted or extended, it will drive connecting plate 17 to move synchronously, and then push two sets of inclined plates 15 through two movable rods 16 respectively, so that the four inclined plates 15 in each set will deflect at an angle around their corresponding rotating parts 14. Since the two sets of inclined plates 15 are staggered, the guide gap and conveying channel shape of the feeding plate 13 will be changed during the deflection process. Secondly, through the extension of cylinder rod 110, the fixed plate 111 will be pushed to rotate upward, which will drive the feeding plate 13 to change the angle around the connection point between the side rod 112 and the feed port 12, so that the tilt angle of the feeding plate 13 will increase, and the speed of material flow along the feeding plate 13 to the feed port 12 will be accelerated. Thus, the material is conveyed in two different ways and can be adjusted as needed. The reciprocating rotation of the motor 24 at ninety degrees causes the semi-circular disk 21 to operate in the same manner. A rubber hammer 22 is fixed at the edge of the semi-circular disk 21. As the semi-circular disk 21 rotates, the rubber hammer 22 will contact the impact plate 23, thereby generating a periodic impact force on the impact plate 23. This causes the material to vibrate during the conveying process, effectively preventing excessive friction between material particles from accumulating and clogging on the feeding plate 13, and ensuring that it can flow smoothly to the feed inlet 12 and enter the vibrating screen body 11.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
