Description

Technical Field

[0001] This utility model relates to the technical field of coke screening equipment, specifically a small coke screening device to prevent screen hole clogging. Background Technology

[0002] Coking coal is the main fuel for blast furnace ironmaking. Its price is relatively low, which can effectively reduce production costs. After coking coal is produced, it contains a large amount of coal powder. Coal powder has poor strength, poor permeability, and poor high-temperature performance, which makes its use risky and can easily cause fluctuations in blast furnace conditions, seriously affecting the quality of molten iron.

[0003] The existing Chinese utility model patent with publication number CN220406332U discloses a coke screening device, including a screening frame, on which several grates are evenly distributed, with gaps between the grates. Inside the frame, a scraper plate that can slide left and right is arranged above the corresponding grates. The lower end of the scraper plate is provided with scraping grooves at the positions corresponding to each grates. The grates pass through the scraping grooves, and the grates divide the lower end of the screening frame into a dust receiving chamber. A cleaning component is arranged in the dust receiving chamber. This invention features a movable scraper and a cleaning component inside the screening machine. The scraper scrapes the grate bars, removing the coke powder adhering to their surface and preventing coke jamming. The cleaning component cleans the coke powder on the bottom wall of the screening machine, removing it from the machine and preventing its accumulation. These features eliminate the need for manual operation, greatly improving the convenience for workers and significantly increasing the cleaning efficiency of the screening machine.

[0004] Existing small coke screening devices are prone to clogging of the coke sieving screen during use, which affects the screening effect of coke granules and causes powder to enter the furnace. At the same time, existing small coke screening devices are not convenient for multi-stage screening and splitting and conveying of coke granules, thus affecting the use of the equipment.

[0028] Please see Figure 1 - Figure 5 In this embodiment, a small coke screening device for preventing screen hole clogging includes: a screening device body 1, a top plate 11 fixedly installed on the top of the screening device body 1, a vibration motor 12 fixedly installed in the middle of the top of the top of the top plate 11, a feed inlet 13 fixedly installed on one side of the top of the top of the top plate 11, three coke screens 14 fixedly installed inside the screening device body 1, a guide plate 15 fixedly installed at the bottom inside the screening device body 1, a bottom plate 16 fixedly installed at the bottom of the screening device body 1, shock-absorbing springs 17 fixedly installed around the bottom of the bottom of the bottom of the bottom plate 16, and a base 18 fixedly installed at the bottom of the shock-absorbing springs 17.

[0029] Specifically, the three coke sieves 14 have different apertures, which can divide the coke into three parts. The coke can be fed through the feed inlet 13, vibrated by the vibrating motor 12, and damped by the shock-absorbing spring 17 at the bottom of the base plate 16.

[0030] Electric chutes 2 are fixedly installed on both sides of the interior of the main body 1 of the screening device. Sliding blocks 21 are movably connected inside the electric chutes 2.

The operation of the electric rotating shaft 22 can drive the brush 23 to rotate, so that the brush 23 can move and brush against the bottom of the coke granules screen 14, thereby cleaning the holes in the middle of the coke granules screen 14 and avoiding the problem of clogging of the holes of the coke granules screen 14, thus improving the practicality of the small coke sieving device that prevents screen hole blockage. The operation of the electric slide rail 3 can drive the moving block 31 to move, and the operation of the rotating roller 32 can drive the scraper 33 to rotate and move, thereby pushing and sending out the powder on the top of the guide plate 15, avoiding the problem of powder accumulation on the top of the guide plate 15.
