[0002] In the sintering process, some particles in the material layer will enter the sintering flue along with the air. Some particles enter the dust collector and are absorbed, while the other part accumulates in the sintering flue. In order to prevent the sintering flue from being blocked, an ash discharging device is needed to clean the particulate dust in the sintering flue. After retrieval, the patent with the application number 202020122229.3 discloses a sintering flue anti-blocking ash discharging device, which belongs to the technical field of sintering production equipment in the metallurgical industry, and includes a dust settling hopper, a sundry passage and an ash discharging passage. The top of the dust settling hopper is used to communicate with the sintering flue; a metal detector is arranged inside the dust settling hopper; one end of the sundry passage is communicated with the dust settling hopper; an adsorbent for adsorbing metal is arranged inside the sundry passage, and the adsorbent is slidably connected with the sundry passage; the top of the ash discharging passage is communicated with the bottom of the dust settling hopper; a first valve and a second valve are arranged at intervals along the up and down direction in the ash discharging passage.

[0003] However, in the actual use process, the applicant found that during the ash discharging process, it is necessary to alternately open and close the first valve and the second valve on the ash discharging passage, making the ash discharging operation inside the sintering flue not very convenient. In view of this, we propose a sintering flue anti-blocking ash discharging device. Summary of the Utility Model

[0018] Please refer to Figures 1-3 as shown, the present utility model provides a technical solution:

[0019] Embodiment 1: A dust discharge device for preventing blockage of a sintering flue, including a dust settling hopper 1, the dust settling hopper 1 is communicated with the sintering flue, the dust settling hopper 1 is fixedly connected to the top of the ash discharge channel 2, a dust collecting hopper 5 is fixedly connected inside the ash discharge channel 2, an ash discharge cylinder body 4 is fixedly connected in the ash discharge channel 2 below the dust collecting hopper 5, the rear end of the ash discharge cylinder body 4 extends to the outside of the ash discharge channel 2, the dust collecting hopper 5 is communicated with the inside of the ash discharge cylinder body 4, a dust inlet 41 is opened at the front end of the ash discharge cylinder body 4, the ash outlet of the dust collecting hopper 5 is communicated with the dust inlet 41, a rotating rod 7 is rotatably connected inside the ash discharge cylinder body 4 through a bearing, a conveying auger 6 is sleeved and fixed on the rotating rod 7, by rotating the rotating rod 7 to drive the conveying auger 6 to rotate, the particulate dust generated inside the sintering flue can be conveyed out along the ash discharge cylinder body 4 through the conveying auger 6, the operation is convenient, and it can prevent backflow during the discharge of dust. The rear end of the rotating rod 7 extends to the outside of the ash discharge cylinder body 4 and is fixedly connected with a hand crank 71. A dust discharge branch pipe 42 is fixedly arranged at the rear end of the rotating rod 7, and a sealing cover 43 is screwed at the lower end of the dust discharge branch pipe 42. During use, the particulate dust generated inside the sintering flue can enter the ash discharge channel 2 through the dust settling hopper 1, and after being concentrated by the dust collecting hopper 5, it is introduced into the ash discharge cylinder body 4 from the dust inlet 41, which can prevent the sintering flue from being blocked. By unscrewing the sealing cover 43 from the lower end of the dust discharge branch pipe 42 and manually rotating the hand crank 71 to drive the rotating rod 7 and the conveying auger 6 to rotate, the particulate dust can be conveyed to the dust discharge branch pipe 42 and discharged from the dust discharge branch pipe 42, realizing the rapid ash discharge of the particulate dust.

[0020] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a metal debris collection frame 3 is inserted in the ash discharge channel 2 above the ash collection hopper 5. A handle 34 is fixedly arranged on the rear side of the metal debris collection frame 3. A filter screen 31 is movably connected inside the metal debris collection frame 3. The filter screen 31 can block the grates and grate bars falling in the sintering channel, so that the grates and grate bars stay in the metal debris collection frame 3. The filter screen 31 moves along the chute opened on the inner wall of the metal debris collection frame 3. Guide columns 33 are fixedly connected in parallel and at equal intervals inside the metal debris collection frame 3. The guide columns 33 movably penetrate through the filter screen 31.

Through the spring 32, when the grates and grate bars fall on the filter screen 31, the filter screen 31 can be buffered. During use, the grates and grate bars falling inside the sintering channel can fall on the filter screen 31 along the ash discharge channel 2 and be blocked by the filter screen 31. During this process, the grates and grate bars drive the filter screen 31 to move downward along the chute, compressing the spring 32. The spring 32 can buffer the filter screen 31 and ensure that the particulate dust can pass through the filter screen 31 smoothly. By holding the handle 34 and pulling out the metal debris collection frame 3 from the ash discharge channel 2, the collected grates and grate bars can be taken out, making the cleaning of the grates and grate bars more convenient.

[0021] Working principle: During use, the particulate dust generated inside the sintering flue can enter the ash discharge channel 2 through the dust settling hopper 1 and be concentrated by the ash collection hopper 5 and then introduced into the ash discharge cylinder 4 from the ash inlet 41, which can prevent the sintering flue from being blocked. By unscrewing the sealing cover 43 from the lower end of the ash discharge branch pipe 42 and manually rotating the hand crank 71 to drive the rotating rod 7 to connect and rotate the conveying auger 6, the particulate dust can be conveyed to the ash discharge branch pipe 42 by the conveying auger 6 and discharged from the ash discharge branch pipe 42, realizing the rapid ash discharge of the particulate dust. During use, the grates and grate bars falling inside the sintering channel can fall on the filter screen 31 along the ash discharge channel 2 and be blocked by the filter screen 31. During this process, the grates and grate bars drive the filter screen 31 to move downward along the chute, compressing the spring 32. The spring 32 can buffer the filter screen 31 and ensure that the particulate dust can pass through the filter screen 31 smoothly. By holding the handle 34 and pulling out the metal debris collection frame 3 from the ash discharge channel 2, the collected grates and grate bars can be taken out, making the cleaning of the grates and grate bars more convenient.
