Description

Technical Field

[0001] This utility model belongs to the field of pellet production technology, and in particular relates to a dust removal device for pellet production. Background Technology

[0002] Pelletizing is a type of lumpy raw material made by wetting powdered materials with water, adding binders, rolling them into balls, and then drying, roasting, and solidifying them. It is mainly used in industrial fields such as steel smelting. During the pelletizing process, a large amount of waste gas is generated, and this waste gas contains a lot of dust, so it needs to be treated for dust removal. Nowadays, bag filters are mostly used for dust removal.

[0003] Chinese patent CN209630968U discloses a dust removal device for oxidized pellet production. The patent describes a device comprising a horizontal dust collector and a multi-tube dust collector. One side of the horizontal dust collector is connected to an inlet pipe, and the outlet of the horizontal dust collector away from the inlet pipe is connected to a first vent pipe. The end of the first vent pipe is connected to the inlet of the multi-tube dust collector. This invention, by installing a horizontal dust collector before the multi-tube dust collector, allows waste gas to be introduced into the horizontal dust collector for primary dust removal, reducing the dust particle content in the waste gas. Then, the waste gas is sent into the multi-tube dust collector for secondary dust removal through the first vent pipe. Because the waste gas contains fewer dust particles after primary dust removal by the horizontal dust collector, the wear on the dust collector and fan impeller is significantly reduced, thereby increasing the impeller's service life. Furthermore, the combined use of the horizontal dust collector and the multi-tube dust collector results in a more ideal dust removal effect.

[0004] However, existing technologies are inconvenient for adsorbing and removing magnetic powder from waste gas, which makes it difficult to recycle and reuse this magnetic powder. At the same time, it also increases the workload of bag filter dust collectors, reduces their dust removal efficiency and service life. Therefore, it is necessary to design a dust removal device for pellet production. Utility Model Content

[0022] Example 1 A preferred embodiment of the dust removal equipment for pellet production provided by this utility model is, for example... Figures 1 to 5 The image shows a dust removal device for pellet production, comprising a bag filter body 1; an exhaust pipe 7 fixedly connected to the upper end of one side of the bag filter body 1; a ash discharge pipe 6 fixedly connected to the bottom end of the bag filter body 1; an adsorption box 3 fixedly connected to the lower end of the other side of the bag filter body 1; the lower end of one side of the adsorption box 3 communicating with the lower end inside the bag filter body 1 via a conduit; and an air inlet pipe 4 fixedly connected to the upper end of the other side of the adsorption box 3; a high-temperature resistant magnetic suction plate 10 disposed inside the adsorption box 3; a chip removal pipe 8 fixedly connected to one side of the bottom end of the adsorption box 3; an installation assembly 5 mounted on the front of the adsorption box 3 for assembling and disassembling the high-temperature resistant magnetic suction plate 10; and a cleaning assembly 2 mounted on the top of the adsorption box 3 for scraping and removing the magnetic powder adsorbed by the high-temperature resistant magnetic suction plate 10.

[0023] It should be noted that some existing dust removal equipment used in pellet production still has certain shortcomings in actual use. It is inconvenient to adsorb and remove magnetic powder in the exhaust gas, which makes it difficult to recycle this magnetic powder. At the same time, it will increase the workload of the bag filter, reduce its dust removal efficiency and service life.

[0024] In a further preferred embodiment of the present invention, the cleaning component 2 includes: a groove 204 formed on one side of the top of the adsorption box 3, and a fixed box 201 fixedly connected to one side of the top of the adsorption box 3; a servo motor 203 fixedly connected to one side of the top of the fixed box 201, the output end of the servo motor 203 extending into the interior of the fixed box 201 and fixedly connected to a threaded rod 202 via a coupling, a threaded plate 206 threadedly connected to the surface of the threaded rod 202, and a cleaning scraper 205 fixedly connected to one side of the threaded plate 206.

[0025] In this embodiment, after dust removal is completed, the valve on the chip removal pipe 8 can be opened, and the servo motor 203 can be started to drive the threaded rod 202 to rotate, so that the threaded plate 206 slides and drives the cleaning scraper 205 to slide down, thereby scraping the magnetic powder adsorbed on one side of the high-temperature magnetic plate 10, and then discharging it through the chip removal pipe 8.

[0026] In a further preferred embodiment of the present invention, limiting grooves 208 are provided at both ends of one side of the fixed box 201, and limiting blocks 207 that slide in cooperation with the inside of the limiting grooves 208 are fixedly connected at both ends of one side of the threaded plate 206.

[0031] In this embodiment, the inclined chute and guide plate 9 are used to guide the scraped magnetic powder, allowing it to be discharged more smoothly through the chip removal pipe 8.

[0032] Example 2 On the basis of Embodiment 1, a preferred embodiment of the dust removal apparatus for pellet production provided by the present utility model is as follows Figures 1 to 5 shown in the figures: the mounting assembly 5 comprises: a mounting groove 509 formed on the front surface of the adsorption box 3, and a fixing groove 501 is formed on the front surface of the adsorption box 3 on one side of the mounting groove 509; a slide rod 502 fixedly connected to the inner wall of the fixing groove 501, a sliding block 504 is slidably connected to the surface of the slide rod 502, a mounting block 508 is fixedly connected to one side of the sliding block 504, a fixing spring 503 is wound around the surface of the slide rod 502, and two ends of the fixing spring 503 are fixedly connected to the inner wall of the fixing groove 501 and one side of the sliding block 504 respectively; a sealing plate 506 arranged on the front surface of the adsorption box 3, one end of the sealing plate 506 is fixedly connected to one end of the high temperature resistant magnetic attraction plate 10, and two ends of one side of the sealing plate 506 are provided with mounting holes 507.

[0033] In this embodiment, the high temperature resistant magnetic attraction plate 10 can be taken out through the sealing plate 506, which facilitates thorough cleaning and maintenance of the high temperature resistant magnetic attraction plate 10. During installation, the elastic force of the fixing spring 503 can be utilized to make the sliding block 504 slide to drive the mounting block 508 to slide and clamp into the mounting hole 507, so as to ensure the firmness and stability of the clamping installation between the sealing plate 506 and the front surface of the adsorption box 3.

[0034] In a further preferred embodiment of the present utility model, a connecting rod 505 is fixedly connected between one sides of the sliding blocks 504, and the connecting rod 505 is used for synchronously driving the two sliding blocks 504 to slide.

[0035] In a further preferred embodiment of the present utility model, one end of the surface of the sealing plate 506 is fixedly connected with a sealing gasket 510, and the sealing gasket 510 is in a shape of a hollow square loop.

[0036] In this embodiment, the hollow square loop-shaped sealing gasket 510 is utilized to improve the sealing performance of the clamping fit between the sealing plate 506 and the inside of the mounting groove 509.

[0037] In a further preferred embodiment of the present utility model, the cross-sectional area of the front surface of the sealing plate 506 is larger than the cross-sectional area of the inner opening of the mounting groove 509, and the other end of the sealing plate 506 is fixedly connected to one end of the high temperature resistant magnetic attraction plate 10 through bolts.

[0038] In this embodiment, the sealing plate 506 with a larger area can completely shield and seal the mounting groove 509.

[0039] In a further preferred embodiment of the present utility model, an engaging structure is formed between one end of the mounting block 508 and the inside of the mounting hole 507, and the depth inside the mounting hole 507 is smaller than the distance from the inner wall of the fixing groove 501 to one side of the sliding block 504.

[0040] In this embodiment, the engagement between the mounting block 508 and the mounting hole 507 improves the firmness and stability of the front engagement installation of the sealing plate 506 and the adsorption box 3.

[0041] In summary, firstly, the high-temperature flue gas is heat exchanged and then transported to the adsorption box 3 through the inlet pipe 4. At this time, the high-temperature resistant magnetic suction plate 10 is used to adsorb and filter the magnetic powder in the flue gas, thereby reducing the dust removal burden on the filter bags inside the bag filter body 1 and extending their service life. The gas after preliminary magnetic filtration passes through the bag filter body 1 for further dust removal and is discharged through the exhaust pipe 7. Meanwhile, after dust removal is completed, the valve on the chip removal pipe 8 can be opened, and the servo motor 203 can be started to drive the threaded rod 202 to rotate. The threaded engagement between the threaded rod 202 and the threaded plate 206 causes the threaded plate 206 to slide and drive the cleaning scraper 205 to slide down. This scrapes the magnetic powder adsorbed on one side of the high-temperature magnetic suction plate 10. The powder is then guided by the guide plate 9 to be discharged more smoothly and completely from the chip removal pipe 8. The servo motor 203 can be started to raise the cleaning scraper 205. The cleaning scraper 205 can then completely cover the groove 204 to prevent the flue gas from entering the interior of the fixed box 201 from the groove 204 during dust removal. Furthermore, by moving the connecting rod 505, the two sliding blocks 504 can slide and compress the fixing spring 503 on the surface of the sliding rod 502, and the mounting block 508 can be slid until it is completely disengaged from the mounting hole 507. Then, the high-temperature magnetic plate 10 can be removed through the sealing plate 506, which facilitates thorough cleaning and maintenance of the high-temperature magnetic plate 10. During installation, first move the connecting rod 505 to make the mounting block 508 slide, then insert the high-temperature magnetic plate 10 through the mounting groove 509, and make the sealing plate 506 lock into the mounting groove 509. At the same time, the sealing gasket 510 is used to improve the sealing performance of the sealing plate 506 and the mounting groove 509. Then, the connecting rod 505 can be released, and the elastic force of the fixing spring 503 can be used to make the sliding block 504 slide and drive the mounting block 508 to slide and lock into the mounting hole 507, ensuring the firm and stable installation of the sealing plate 506 and the adsorption box 3.
