Description

Technical Field

[0001] The utility model relates to the technical field of powder iron removal processing, in particular to a powder material iron removal device for biomass fuel production. Background Art

[0002] Biomass fuel powder may be mixed with metal impurities during the processing and handling process. These impurities may come from the wear and tear of production equipment, improper maintenance, or the raw materials themselves. Metal impurities not only affect the combustion efficiency of biomass fuel, but may also cause damage to combustion equipment. Therefore, in the process of biomass fuel processing, it is very necessary to use an iron removal device. The iron filings in the biomass fuel powder raw materials can be separated by the iron removal device to reduce the metal content in the raw material powder and improve the quality of the produced biomass fuel.

[0003] For example, the patent with announcement number CN217249676U discloses a biomass fuel powder iron removal device, including a base, a iron removal box fixedly installed on the top of the base, a collection slide fixedly installed on the bottom end of the iron removal box, a motor fixedly installed on the inside of the base, the motor shaft is connected to one end of the rotating shaft, an electromagnetic rod is fixedly installed on the other end of the rotating shaft, and the rotating shaft passes through the iron removal box and the collection slide, multiple groups of electromagnetic blocks are fixedly installed on the outer end of the electromagnetic rod, the iron removal box is connected to the top with a powder blowing pipe, a blower is fixedly installed on the right side of the powder blowing pipe, the top right side of the powder blowing pipe is connected to a powder pipe 1, the bottom right side of the front end of the iron removal box is connected to an iron removal pipe, the iron removal pipe is installed with an electromagnetic valve 1, and a central processing unit and a timer are fixedly installed on the upper right side of the iron removal box. The electromagnetic rod and the electromagnetic block are driven to rotate slowly by the rotating shaft, so that the iron powder in the powder can be adsorbed on the electromagnetic block and the electromagnetic rod. Increasing the contact area with the powder by multiple groups of electromagnetic blocks is conducive to improving the iron removal rate.

[0004] However, the iron removal device in the above technology still has the following problems:

[0005] Although the above technology can adsorb iron powder in the powder through the electromagnetic rod and multiple electromagnets to achieve the effect of iron removal, as the amount of iron powder adsorbed on the electromagnetic rod and the electromagnet increases, the iron powder adsorbed on the electromagnetic rod and the electromagnet gradually becomes thicker, which will cause the magnetic attraction effect of the electromagnetic rod and the electromagnet on the iron powder to gradually decrease. Even when the electromagnetic rod and the electromagnet rotate, the iron powder adsorbed on the electromagnetic rod and the electromagnet will be thrown off, causing the iron powder to be mixed into the finally collected powder, resulting in poor iron removal effect.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figure 1 - Figure 8 A powder material iron removal device for biomass fuel production includes a base 1, a distribution pipe 2 is provided above the base 1, a feed hopper 3 is fixedly connected to the top of the distribution pipe 2, a discharge port 201 is penetrated on one side of the bottom of the distribution pipe 2, two iron powder outlets 202 are penetrated on the side of the distribution pipe 2 away from the discharge port 201, and a magnetic attraction component is provided in each of the two iron powder outlets 202, one side of the two magnetic attraction components is connected to a support rod 4, the bottom of the support rod 4 is connected to the base 1, and the side of the support rod 4 away from the distribution pipe 2 is connected to two scraping components, and the two scraping components are respectively connected to the two magnetic attraction components.

[0028] like Figure 1 - Figure 8 As shown, the structure of the powder material iron removal device for biomass fuel production in the present invention is similar to that of the existing powder material iron removal device for biomass fuel production. The main improvement of the present invention is that the adsorbed iron powder can be scraped off, thereby maintaining continuous and stable adsorption of the iron powder tank in the powder material and improving the iron removal effect. Figures 1 to 8 As shown, when the powder material iron removal device for biomass fuel production in the utility model is in use, the powder raw material is added into the distribution pipe 2 through the top feed hopper 3, and gradually falls in the distribution pipe 2. First, the iron powder in the powder raw material is sucked out by two magnetic components, while the non-iron powder continues to fall and falls out through the discharge port 201. A material bucket can be placed below the discharge port 201 for collection. After the iron powder is adsorbed by the magnetic component, it is removed through the iron powder outlet 202, and the iron powder adsorbed on the magnetic component is scraped off by the scraping component to complete the powder iron removal operation. The scraping component ensures the continuous adsorption effect of the magnetic component on the iron powder, greatly improving the adsorption effect on the iron powder.

[0029] like Figure 1 - Figure 4 As shown, support plates 5 are fixedly connected to both sides of the distribution pipe 2, and the two support plates 5 are fixedly connected to the base 1. The bottom of the distribution pipe 2 is suspended by the two support plates 5, so that the powder collection bucket can be placed below the discharge port 201.

[0030] like Figure 1 - Figure 8As shown, the magnetic attraction assembly includes a T-shaped mounting seat 6, a magnetic ring 7 and a T-shaped fixing seat 8. The wider side of the T-shaped mounting seat 6 is connected to the support rod 4, and the inner wall of the magnetic ring 7 is slidingly connected to the outer wall of the thinner end of the T-shaped mounting seat 6. A threaded groove 601 is provided at the end of the T-shaped mounting seat 6 away from the support rod 4. The thinner end of the T-shaped fixing seat 8 is threadedly connected to the threaded groove 601, and the thicker end of the T-shaped fixing seat 8 is against the end of the magnetic ring 7 away from the support rod 4. The side of the T-shaped mounting seat 6 close to the support rod 4 is connected to a driving mechanism. When installing the magnetic attraction component, first put the magnetic ring 7 on the outer wall of the thinner end of the T-shaped mounting seat 6, then insert the thinner end of the T-shaped fixing seat 8 into the threaded groove 601 at the end of the T-shaped mounting seat 6, and tighten the thread. Cooperate with the T-shaped mounting seat 6 to squeeze the magnetic ring 7 on the inside, thereby completing the installation and fixation of the magnetic ring 7. When the magnetic force of the magnetic ring 7 decreases or the magnetic ring 7 is damaged, it is convenient to disassemble and replace the magnetic ring 7. It should be noted that the width of the magnetic ring 7 is slightly larger than the length of the thinner end of the T-shaped mounting seat 6, and the length of the thinner end of the T-shaped fixing seat 8 needs to be able to be threaded and tightened with the threaded groove 601.

[0031] like Figure 1 - Figure 8 As shown, the driving mechanism includes a driving motor 9, a driving belt 10, two belt rollers 11 and two connecting shafts 12. The driving motor 9 is fixedly connected to the side of the support rod 4 away from the T-shaped mounting seat 6. The two connecting shafts 12 are respectively fixedly connected to the side of the two T-shaped mounting seats 6 close to the support rod 4. The ends of the two connecting shafts 12 away from the T-shaped mounting seat 6 both pass through the support rod 4 and are respectively fixedly connected to the two belt rollers 11. The two connecting shafts 12 are both rotatably connected to the support rod 4. The driving belt 10 is sleeved with two belt rollers 11 and rotatably connected to the two belt rollers 11. The output shaft of the driving motor 9 is fixedly connected to the end of one of the belt rollers 11 away from the connecting shaft 12. When performing the iron removal operation, the drive motor 9 is started to drive the adjacent belt roller 11 to rotate, and then the other belt roller 11 is synchronously driven to rotate through the drive belt 10. When the belt roller 11 rotates, the connecting shaft 12 penetrates the support rod 4 to drive the T-shaped mounting seat 6 at the other end to rotate, thereby driving the magnetic ring 7 installed on the T-shaped mounting seat 6 to rotate, and the iron powder adsorbed on the magnetic ring 7 can be continuously rotated and sent out from the iron powder outlet 202, and then the iron powder adsorbed on the magnetic ring 7 is scraped off by the scraping component, so that there is no iron powder on the part of the magnetic ring 7 that is rotated back into the iron powder outlet 202, which can form a continuous and stable adsorption effect on the iron powder.

[0032] like Figure 1 - Figure 5As shown, the scraping assembly includes a connecting rod 13 and a U-shaped scraping rod 14. One end of the connecting rod 13 is fixedly connected to the side of the support rod 4 away from the feed pipe 2, and the connecting rod 13 is located at the midline position of the magnetic ring 7. The inner wall of the U-shaped scraping rod 14 is slidably connected to the outer wall of the end of the magnetic ring 7 away from the feed pipe 2, and one side of the U-shaped scraping rod 14 is connected to the connecting rod 13. When the magnetic ring 7 rotates and absorbs the iron powder, the inner side of the U-shaped scraping rod 14 is pressed against the outer wall of the magnetic ring 7. As the magnetic ring 7 rotates, the U-shaped scraping rod 14 continuously scrapes off the iron powder absorbed on the magnetic ring 7. The direction of rotation of the magnetic ring 7 is from the bottom of the iron powder outlet 202 to the position of the U-shaped scraping rod 14, so that the scraped iron powder can fall from under the U-shaped scraping rod 14, thereby avoiding the possibility of the scraped iron powder being re-absorbed by the magnetic ring 7.

[0033] like Figure 2 - Figure 4 As shown, a telescopic slot 101 is formed on the side of the connecting rod 13 near the U-shaped scraping rod 14. A telescopic block 15 is slidably connected to the telescopic slot 101. A threaded rod 16 is rotatably connected to the inner wall of one end of the telescopic slot 101. The other end of the threaded rod 16 sequentially passes through the telescopic block 15 and the end of the connecting rod 13 away from the support rod 4, and is fixedly connected to a hand-tightening cap 17. The threaded rod 16 is threadedly connected to the telescopic block 15. By sliding between the telescopic block 15 and the telescopic slot 101, when replacing the magnetic ring 7, the threaded rod 16 can be rotated by the hand-tightening cap 17, thereby driving the U-shaped scraping rod 14 to move outward from the magnetic ring 7, making it easier to remove and replace the magnetic ring 7.

[0034] like Figure 1 - Figure 5 As shown, a connecting plate 18 is fixedly connected to the side of the connecting rod 13 away from the U-shaped scraping rod 14. The connecting plate 18 extends downward and is fixedly connected to an iron powder box 19. The iron powder box 19 is located directly below the U-shaped scraping rod 14. The iron powder box 19 is fixed below the U-shaped scraping rod 14 by the connecting plate 18, so that the iron powder scraped by the U-shaped scraping rod 14 can be collected.

[0035] like Figure 1 - Figure 5 As shown, a T-shaped slot 102 is provided on one side of the base 1 close to the support rod 4, and a T-shaped slider 20 is slidably connected to the T-shaped slot 102. The thinner end of the T-shaped slider 20 passes through the T-shaped slot 102 and is fixedly connected to the bottom of the support rod 4. When removing or replacing the magnetic ring 7, the support rod 4 can be moved outward by sliding the T-shaped slider 20 and the T-shaped slot 102, thereby removing the magnetic ring 7 from the iron powder outlet 202, making it easier to remove and replace the magnetic ring 7. The sliding between the T-shaped slider 20 and the T-shaped slot 102 has a certain friction resistance, which prevents the T-shaped slider 20 from sliding and shifting in the T-shaped slot 102 when the magnetic ring 7 rotates.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
