Description

Technical Field

[0001] The utility model relates to the field of powder material manufacturing, in particular to a drum-type screening device for soft magnetic manganese-zinc ferrite. Background Art

[0002] Currently, the pre-calcination process primarily involves sifting red ball fines through a vibrating feeder. This results in inadequate screening and is prone to blockage, leading to pre-calcination interruptions and impacting production continuity and product quality. Due to the characteristics of the material, the feed flow rate fluctuates during production. Failure to promptly identify and clean the screen during production results in poor pre-calcination flow consistency, hindering the control of magnetization and chloride ion levels during the pre-calcination process. This ultimately impacts the sintered density and shrinkage ratio of the product.

[0003] The patent application with publication number CN211051891U discloses a steel ball vibrating screen for manganese-zinc ferrite sand grinding, which includes, from top to bottom: a lower hopper, a vibrating bin, a vibrating box and a bracket. A vibrating screen is contained between the vibrating bin and the vibrating box. Motors are installed on both sides of the vibrating box. A spring bracket is installed between the vibrating box and the bracket. A qualified product discharge port is opened on the vibrating bin, and a waste product discharge port is opened at the bottom of the vibrating box.

[0004] After the prior art device has been used for a period of time, the spring bracket supporting the lower portion is easily deformed, which affects the use of the device.

[0005] Therefore, a new technical solution is needed to solve the above technical problems. Utility Model Content

[0031] like Figure 1-4 As shown, a drum-type screening device for soft magnetic manganese-zinc ferrite includes a motor 1, a drum, a reducer 6, a sprocket 11, and a striking hammer 12. The drum is provided with an outer drum housing 17, which is fixedly mounted on a base 10 via a mounting base 19. The drum is placed on the base 10 via an outer drum bracket 9. The motor 1 is provided on the side of the drum on the base 10. The motor 1 and the drum are linked by a sprocket 11. The drum is provided with a striking hammer 12 and a striking block 13 on the side of the drum. The output shaft of the motor 1 is connected to the drum via a sprocket 11. The output shaft of the motor 1 is connected to the output shaft of the motor 1 via a coupling 2. The reducer 6 is located between the motor 1 and the coupling 2, and a small transparent cover 3 is located between the reducer 6 and the coupling 2.

[0032] The drum includes an external drum screen barrel 4 and a drum screen barrel 5 sleeved inside the drum screen barrel 4. The drum screen barrel 4 and the drum screen barrel 5 are coaxially installed. The drum screen barrel 4 and the drum screen barrel 5 are fixed in position by a connecting fixing rod 18. The side wall of the drum screen barrel 5 is a stamped plate screen 16. The drum screen barrel 5 is equipped with a stainless steel stamped plate screen with a 3mm aperture, which greatly increases the service life of the screen, increases the fine powder screening capacity, and increases the screening efficiency of the fine powder of the drying kiln ball material.

[0033] The outer drum 4 is fitted with an outer drum housing 17, which fits over the drum 4 with a gap between them. The bottom of the housing 17 serves as a fine powder discharge port 14. A striking hammer 12 is fixed to the outside of the drum 4, and below it is a striking block 13 fixed to the outer wall of the drum 4. The addition of the striking hammer 12 to the drum 4 significantly reduces the buildup of fine powder on the walls of the drum 4 and the sieve barrel 5. The addition of the striking block 13 to the drum 4 also significantly reduces the wear and tear of the hammer 13 on the exterior of the device.

[0034] A feed pipe 15 is installed on the side of the drum outer barrel 4, with its discharge port extending into the drum sieve barrel 5. A supporting roller 7 is installed below the drum outer barrel 4, with a supporting roller support 8 at its base. Support 8 is located on a base 10, outside the outer barrel support 9. The outer barrel support 9 and the puller 7 are installed outside the drum, making the device more stable when rolling and screening via motor 1.

[0035] When the device is used, after pre-burning is turned on, the ball material in the pre-burning hopper is weighed by a belt scale and then enters the drying kiln for drying. It then enters the drum screen barrel 5 from the feed pipe 15 above the drum screen outer cylinder 4. During the normal feeding process, the motor 1 is connected to the coupling 2 and the coupler to drive the sprocket 11 to link the drum to achieve normal operation. After the ball material enters the drum screen barrel 5 and is screened, it will run at a uniform speed to the end of the drum screen until it enters the rotary kiln for sintering. During the operation of the drum screen barrel 5, the hammer 12 on the outer wall of the drum screen outer cylinder 4 will also maintain a continuous knocking state to stabilize the fine powder screening efficiency of the drum screen barrel 5. By increasing the effective screening area of ​​the drum screen barrel 5, the proportion of fine powder entering the rotary kiln is greatly reduced, thereby extending the period of rotary kiln wall adhesion and improving the consistency of pre-burning.

[0036] The embodiments described above are merely descriptions of preferred implementation methods of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made by technical personnel in this field to the technical solution of the present invention should be included in the scope of protection determined by the claims of the present invention.
