Abstract
Description
Technical Field
[0001] The utility model relates to a sorting device, in particular to a quicklime sorting device for sintering production, belonging to the technical field of sintering production. Background Art
[0002] The main component of quicklime is CaO, which is digested into slaked lime when it meets water and acts as a binder in the sintering material, increasing the spheroidization of the mixture, improving the strength of the mixture after spheroidization, improving the particle size composition of the sintering material, and improving the air permeability of the material layer; secondly, because the slaked lime has extremely fine particles and its specific surface area is about 100 times larger than before digestion, it can better contact with other components in the mixture and react with solid-liquid phase more quickly, which not only accelerates the sintering process and prevents the existence of free CaO, but also can be evenly distributed in the sintering material, which is beneficial to the chemical reaction in the sintering process.
[0003] Existing patent application number 202121057897.3: The utility model discloses a quicklime sorting device for sintering production, which is installed between the quicklime silo and the ash-making pipe, and includes a feed pipe and a discharge chute. The feed pipe is connected to the ash-making pipe, and the other end is connected to a vertical downcomer; the discharge chute extends obliquely downward to above the operating platform; the vertical downcomer is connected to the feed pipe and the discharge chute, and a vertical filter plate is installed at the connection between the upper end of the downcomer and the feed pipe; an inclined filter plate is provided at the lower end of the vertical filter plate obliquely downward; the lower end of the vertical downcomer is connected to the quicklime silo; the lower end of the discharge chute is connected to the storage silo.
[0004] When the above equipment is in use, quicklime is directly sucked into the device and filtered through the filter plate. Small particles of quicklime will pass through the filter and fall directly into the quicklime bin for collection. Large particles of quicklime will remain on the surface of the filter and slide from the surface of the filter to the storage bin for collection, thereby realizing quicklime sorting. However, when used for a long time, a large amount of lime powder will accumulate on the filter, causing the filter to be blocked, resulting in poor sorting quality and low sorting efficiency, or even the filter being blocked and completely unable to sort. The equipment needs to be paused and the filter needs to be cleaned before filtering can continue, which is inconvenient to use. Utility Model Content

[0025] The embodiment of the utility model provides a quicklime sorting device for sintering production.
[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4, a quicklime sorting device for sintering production, comprising a screening box 1 and a sorting box 2, wherein one side of the top of the sorting box 2 is fixedly connected to a base 4, the top of the base 4 is provided with a motor 5, one side of the motor 5 is fixedly connected to a transmission shaft 20, the outer side of the transmission shaft 20 is fixedly connected to a fan wheel 21, the outer side of the fan wheel 21 is fixedly connected to a plurality of fan blades 7, one end of the transmission shaft 20 is fixedly connected to a runner 11, one side of the runner 11 is rotatably connected to a first rotating column 22, the outer side of the first rotating column 22 is fixedly connected to a connecting rod 12, one end of the connecting rod 12 is fixedly connected to a second rotating column 23, both ends of the second rotating column 23 are rotatably connected to a rotating plate 24, a screen 13 is fixedly connected to the top of the rotating plate 24, two T-shaped sliders 25 are fixedly connected to both sides of the screen 13, and a plurality of slide slot seats 14 are arranged on the outer sides of the T-shaped sliders 25, and the plurality of slide slot seats 14 are fixedly connected to the screening box 1.
[0027] When the utility model is in use: the user first turns on the device, and then the motor 5 on the top of the base 4 starts to start. The start of the motor 5 will drive the transmission shaft 20 fixedly connected on one side to rotate, and the rotation of the transmission shaft 20 will drive the fan wheel 21 fixedly connected on the outside to rotate, and the rotation of the fan wheel 21 will drive the multiple fan blades 7 fixedly connected on the outside to rotate.
[0028] When the transmission shaft 20 drives the impeller 21 to rotate, it also drives the rotating wheel 11 fixed at one end to rotate. The rotation of the rotating wheel 11 drives the first rotating column 22 rotatably connected to one side to rotate. The rotation of the first rotating column 22 drives the connecting rod 12 fixedly connected on the outside to move up and down.
[0029] When the connecting rod 12 moves up and down, it will drive the second rotating column 23 fixedly connected at one end to move up and down. The up and down movement of the second rotating column 23 will drive the rotating plate 24 rotatably connected at both ends to move up and down. The up and down movement of the rotating plate 24 will drive the screen 13 fixedly connected at the top to move up and down.
[0030] Since two T-shaped sliders 25 are fixedly connected on both sides of the screen 13, a slide slot seat 14 is arranged on the outer side of the multiple T-shaped sliders 25, and the multiple slide slot seats 14 are fixedly connected to the screening box 1, the T-shaped slider 25 is limited by the slide slot seat 14 and can only move up and down inside the slide slot seat 14.
[0031] Because the T-shaped slider 25 is fixedly connected to the screen 13, the screen 13 is also limited by the slide seat 14 and can only move up and down but not deviate in other directions. Therefore, when the rotating wheel 11 drives the first rotating column 22 to rotate, the first rotating column 22 will drive the connecting rod 12 to move up and down.
[0032] Then quicklime is poured from the feed hopper 3 at the top of the screening box 1 , and then the quicklime falls onto the screen 13 at the bottom of the feed hopper 3 for filtration, and large particles of quicklime will remain on the top of the screen 13 , and smaller particles of quicklime will fall from the openings on the screen 13 .
[0033] This arrangement allows the screen 13 to shake up and down all the time, so that when the screen 13 is filtering quicklime, the quicklime will not accumulate on the top of the screen 13 due to long-term filtration, causing the screen 13 to be blocked, so that the equipment can filter for a long time, thereby improving the sorting efficiency of the equipment.
[0034] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 4 A sliding plate 15 is provided at the bottom of the screen 13, a receiving plate 16 is provided at the bottom of the sliding plate 15, a baffle plate 17 is provided on one side of the receiving plate 16, the sliding plate 15, the receiving plate 16 and the baffle plate 17 are all fixedly connected to the screening box 1, a partition 9 is provided at the bottom of the baffle plate 17, a second conveyor belt 10 and a first conveyor belt 8 are respectively provided on both sides of the partition 9, a discharge pipe 18 is fixedly connected to one side of the screening box 1, a discharge port 19 is provided on one side of the discharge pipe 18, a feed hopper 3 is fixedly connected to the top of the screening box 1, and an air inlet net 6 is fixedly connected to one side of the screening box 1.
[0035] When the utility model is in use, after the quicklime is filtered through the screen 13, large quicklime particles will remain on the top of the screen 13. Because the screen 13 is arranged obliquely and the screen 13 is constantly shaking up and down, the large quicklime particles remaining on the top of the screen 13 will move to the lower side of the screen 13.
[0036] Then, the large quicklime on the top of the screen 13 will fall into the inside of the discharge pipe 18 on one side, and then fall through the inside of the discharge pipe 18 to the top of the first conveyor belt 8 at the bottom, and then be conveyed out from the left side of the equipment by the first conveyor belt 8.
[0037] Then, the small quicklime particles sieved out from the holes of the screen 13 will fall to the top of the sliding plate 15 below. Since the sliding plate 15 is also arranged obliquely, the quicklime on the top of the sliding plate 15 will also move to the lower part of the sliding plate 15 and then fall from the top of the sliding plate 15.
[0038] Then, the wind generated by the rotating plurality of fan blades 7 will blow toward the falling quicklime through the holes provided in the air inlet net 6 , blowing smaller particles of quicklime toward the top of the receiving plate 16 , and then sliding out from the discharge port 19 .
[0039] The slightly larger quicklime, because it is not blown by the wind, falls to the top of the baffle plate 17, then slides from the top of the baffle plate 17 to the top of the second conveyor belt 10, and is then conveyed to the left side of the equipment by the second conveyor belt 10.
[0040] This arrangement can transport quicklime of three different sizes through three different outlets, namely the first conveyor belt 8, the second conveyor belt 10 and the discharge port 19, through multiple sorting, making the sorting more detailed and allowing the machine to be sorted without stopping, which not only improves the sorting efficiency but also greatly improves the sorting quality.
