Description

Technical Field

[0001] The utility model belongs to the technical field of sintering furnaces, and specifically relates to a sintered return ore device capable of controlling particle size. Background Art

[0002] With the release of production capacity, the consumption of scrap steel is increasing. The amount of scrap steel is gradually decreasing with consumption, the price of scrap steel is rising, and the supply of externally purchased scrap steel is almost cut off. Only the undersize material of self-produced sinter can be used to replace scrap steel. During the blast furnace production process, about 10% of sintered return ore will be generated. After the small-sized sintered ore is cold-fixed and formed, it is returned to the blast furnace, realizing resource recycling, reducing environmental pollution, and reducing energy consumption.

[0003] After retrieval, CN218554699U discloses a sintered return ore device capable of controlling particle size, including two vertical rods.

The processing box is internally communicated with the discharge pipe. A discharge hopper is fixedly connected to the bottom surface of the processing box, and the processing box is internally communicated with the discharge hopper. A pushing device is arranged inside the processing box. Through the arrangement of the pushing device, when the raw materials with larger particle size on the vibrating screen accumulate, the pushing plate moves to push the raw materials with larger particle size on the vibrating screen towards the second discharge port and discharges them from the second discharge port. In this way, the vibrating screen can be prevented from being blocked by the raw materials with larger particle size, and the practicability of the device is improved.

[0004] However, through the exploration of the inventor, it is found that this technical solution still has at least the following defects:

Specific Embodiments

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0026] As Figures 1 to 4As shown in the figure, a sintered return ore device with controllable particle size includes a support frame 1. A partition 3 is installed at the central position of the support frame 1. Leakage holes 2 are formed in the partition 3. Splash-proof plates 4 are installed on both sides of the partition 3. The splash-proof plates 4 and the side wall of the support frame 1 form a cleaning cavity 5. A first collection box 6 is installed at the bottom of the cleaning cavity 5. A second collection box 7 is installed at the bottom of the partition 3. A cleaning component is installed on the support frame 1. Among them, the raw materials to be screened can be evenly transported onto the partition, and the screening operation is completed through the leakage holes on the partition. The second collection box 7 is used to collect the raw materials passing through the leakage holes, and the first collection box 6 is used to collect large-particle raw materials.

[0027] The cleaning component includes an adjusting roller 10. A guiding groove 11 is formed in the adjusting roller 10. An arched bracket 15 is slidably arranged on the guiding groove 11, and the arched bracket 15 is slidably connected to the side wall of the support frame 1. A plug board 19 is installed at the bottom of the arched bracket 15. A scraping plate 20 is slidably arranged on the plug board 19. The bottom of the scraping plate 20 is slidably connected to the surface of the partition 3. A driving motor 13 is installed on one side of the adjusting roller 10. Starting the driving motor drives the adjusting roller to rotate. The arched bracket on the adjusting roller can push the plug board to move left and right. The movement of the plug board drives the scraping plate to slide, and the large-particle raw materials on the partition are transported from the splash-proof plate to the first collection box. By the above method, it is not necessary to frequently disassemble the equipment, the operation is simpler, and the use efficiency is higher.

[0028] As Figures 1 to 4 shown in the figure, in the specific implementation manner, transfer boxes 8 are movably inserted into the first collection box 6 and the second collection box 7, and the transfer boxes 8 are in contact with the side walls of the corresponding first collection box 6 and second collection box 7. A handle 9 is installed on the surface of the transfer box 8, and an anti-slip sleeve is installed on the handle 9. The operator takes out the raw materials inside the first collection box 6 and the second collection box 7 through the transfer box 8, and it is convenient to pull the transfer box 8 through the handle 9. Among them, the raw materials that need to return to the ore inside the transfer box 8 are poured back into the sintering furnace.

[0029] As Figures 1 to 4 shown in the figure, further, the splash-proof plate 4 is in an inclined state. The top of the splash-proof plate 4 and the top of the support frame 1 are on the same straight line. The connection between the splash-proof plate 4 and the partition 3 is rounded. The raw materials burned inside the sintering furnace are transported onto the partition 3. Since the splash-proof plate 4 is provided on the partition 3, it is ensured that the raw materials are on the partition 3. The raw materials can be filtered through the leakage holes 2 on the partition 3. At this time, the small-particle raw materials will fall into the second collection box 7 to complete the collection function.

[0030] As Figures 1 to 4As shown in the figure, rotating shafts are installed at both ends of the adjusting roller 10, bearings are sleeved on the rotating shafts, bearing seats 12 are clamped on the outer walls of the bearings, the side walls of the bearing seats 12 are connected to the support frame 1, and the outer walls of the bearing seats 12 are connected to the outer shell of the driving motor 13. When the driving motor 13 is started, the adjusting roller 10 is driven to rotate by the driving motor 13. At this time, the rotating shaft of the adjusting roller 10 rotates inside the bearing and the bearing seat 12, and the friction during rotation is reduced by the bearing and the bearing seat 12.

[0031] As Figures 1 to 4 shown in the figure, the guide groove 11 is an annular groove. A guide slider 14 is installed on the arched bracket 15. The guide slider 14 is slidably connected to the guide groove 11. The horizontal length of the guide groove 11 is greater than the maximum distance between the two splash-proof plates 4. Fixed seats 18 are symmetrically installed on the side wall of the support frame 1. A sliding rod 17 is fixedly installed through the fixed seats 18. A sliding plate 16 is slidably arranged on the sliding rod 17. The end of the sliding plate 16 is connected to the side wall of the arched bracket 15. During the rotation of the adjusting roller 10, the guide groove 11 on the adjusting roller 10 rotates synchronously, and the guide slider 14 can move synchronously. The bottom of the guide slider 14 is connected to the arched bracket 15, and the sliding plate 16 on the side wall of the arched bracket 15 slides in the sliding rod 17. Thus, the whole arched bracket 15 is limited, and then the guide slider 14 can drive the arched bracket 15 to move. The arched bracket 15 and the insertion plate 19 drive the scraping plate 20 to slide. The scraping plate 20 slides on the partition 3, and then the large-particle raw materials on the surface are pushed outwards.

[0032] As Figures 1 to 4 shown in the figure, a plug rod 21 is fixedly installed on the inner side wall of the arched bracket 15. The end of the plug rod 21 is inserted into the inner wall of the scraping plate 20. A baffle 22 is fixedly installed on the surface of the scraping plate 20. A return spring 23 is sleeved on the plug rod 21. One end of the return spring 23 is clamped on the inner side wall of the arched bracket 15, and the other end of the return spring 23 is clamped on the baffle 22. During the vertical movement of the scraping plate 20, the scraping plate 20 slides on the plug rod 21, and the baffle 22 squeezes the return spring 23 at this time. The return spring 23 facilitates the later reset of the scraping plate 20.

[0033] The implementation principle of a sintered ore return device with controllable particle size in this embodiment is as follows:

[0034] First, the raw materials burned inside the sintering furnace are conveyed onto the partition 3. Since splash-proof plates 4 are provided on the partition 3, the raw materials are ensured to be on the partition 3. The raw materials can be filtered through the leakage holes 2 on the partition 3. At this time, the small-particle raw materials will fall into the second collection box 7 to complete the collection function, while the large-particle raw materials remain on the partition 3. Then, the operator starts the cleaning component to start the cleaning operation.

[0035] Start the drive motor 13, and drive the adjusting roller 10 to rotate through the drive motor 13. At this time, the rotating shaft of the adjusting roller 10 rotates inside the bearing and the bearing housing 12, and the bearing and the bearing housing 12 reduce the frictional force during the rotation. During the rotation of the adjusting roller 10, the guide groove 11 on the adjusting roller 10 rotates synchronously, and the guide slider 14 can move synchronously. The bottom of the guide slider 14 is connected to an arched bracket 15, and the slide plate 16 on the side wall of the arched bracket 15 slides in the slide bar 17. Furthermore, the whole arched bracket 15 is limited, and then the guide slider 14 can drive the arched bracket 15 to move. The arched bracket 15 and the insertion plate 19 drive the scraping plate 20 to slide, and the scraping plate 20 slides on the baffle 3, and then pushes the raw materials with large particles on the surface outwards. When it moves to the splash-proof plate 4, at this time, the scraping plate 20 can slide upwards along the insertion plate 19 to ensure that the scraping plate 20 can always fit with the splash-proof plate 4, and finally the large-particle raw materials can be pushed into the first collection box 6, and finally the collection function is completed.

[0036] During the vertical movement of the scraping plate 20, the scraping plate 20 slides on the insertion rod 21, and the baffle 22 squeezes the return spring 23 at this time, and the return spring 23 facilitates the later reset of the scraping plate 20.

[0037] After the treatment is completed, the operator takes out the raw materials inside the first collection box 6 and the second collection box 7 through the transfer box 8, and it is convenient to pull the transfer box 8 through the handle 9. Among them, the raw materials that need to be returned to the mine inside the transfer box 8 are poured back into the sintering furnace again.
