Technical Field

[0001] This invention relates to the field of slag powder treatment equipment, specifically a pretreatment device for steel slag powder. Background Technology

[0002] Scrap steel refers to scrap steel parts contained in scrapped equipment and components. These parts are usually processed and reused, so a crushing device is needed to pre-treat the steel slag.

[0003] While existing crushing devices can effectively crush waste slag, they lack a structure for screening slag powder. Consequently, they can only be directly recycled after crushing and cannot be graded, thus reducing the processing efficiency of existing devices. Therefore, we propose a pretreatment device for steel slag powder. Summary of the Invention

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-5 A pretreatment device for steel slag powder includes a housing 1, a crushing box 2 fixedly mounted on the top of the housing 1, a motor 3 fixedly mounted on the outer wall of the crushing box 2, a gear 4 fixedly mounted on the output shaft of the motor 3, a primary crushing rod 5 fixedly mounted on the outer wall of the gear 4, a fixed platform 6 fixedly mounted on the side wall of the housing 1 near the motor 3, a second motor 7 fixedly mounted on the top of the fixed platform 6, a cam 8 fixedly mounted on the output shaft of the second motor 7, a receiving groove 15 and an installation groove 22 respectively opened on the inner wall of the housing 1, a strip groove 23 opened on the outer wall of the housing 1, a crossbar 17 fixedly mounted on the inner wall of the installation groove 22, and a crossbar 17 on the outer wall of the crossbar 17. A return spring 18 is sleeved on the wall. A limit block 16 is slidably connected to the inner wall of the receiving groove 15. A screen 9 is fixedly mounted on the outer wall of the limit block 16. A motor 10 is fixedly mounted on the back of the box 1. A lead screw 19 is fixedly mounted on the output shaft of the motor 10. A scraper 20 is threadedly connected to the outer wall of the lead screw 19. A sealing plate 21 is fixedly mounted on the outer wall of the scraper 20. A guide plate 24 is fixedly mounted on the front of the box 1. A secondary grinding box 11 is provided at the end of the guide plate 24. A motor 12 is fixedly mounted on the outer wall of the secondary grinding box 11. A gear 13 is fixedly mounted on the output shaft of the motor 12. A discharge groove 14 is provided at the bottom of the secondary grinding box 11.

[0024] In the above structure, the setup of the housing 1, crushing box 2, motor 1 3, gear 1 4, primary crushing rod 5, fixed platform 6, motor 2 7, cam 8, and screen 9 allows the user to directly feed the slag into the housing 1 during use. The two primary crushing rods 5 crush the slag powder, causing it to fall onto the screen 9. The operation of motor 2 7 causes cam 8 to move the screen 9, which in turn causes limit block 16 to compress return spring 18, making the screen 9 reciprocate. This increases the contact area between the screen 9 and the slag powder, thereby achieving the effect of screening the slag powder and ensuring that the device can classify the slag powder.

[0025] In a preferred embodiment, the diameter of the groove 23 is adapted to the diameter of the sealing plate 21, and the sealing plate 21 is made of rubber.

[0026] In the above structure, the strip groove 23 and the sealing plate 21 structure allow the user to seal the strip groove 23 through the sealing plate 21 during operation, thereby ensuring that the slag powder cannot leak through the strip groove 23 when the screen 9 is screening the slag powder, thus ensuring the normal operation of the device.

[0027] In a preferred embodiment, the inner wall of the receiving groove 15 is slidably connected to the outer wall of the scraper 20, and the scraper 20 is made of galvanized iron metal.

[0028] In the above structure, through the scraper 20 structure, after the screening operation is completed, the user can scrape off the residual powder on the screen 9 by moving the scraper 20, so that the guide plate 24 can guide the discharged powder into the secondary grinding box 11 for secondary crushing operation. This makes it easier for the user to clean the residue on the screen 9, thereby improving the user's maintenance efficiency of the device and also improving the automation of the device.

[0029] In a preferred embodiment, a secondary crushing rod is fixedly mounted on the outer wall of the second gear 13, and the interior of the secondary grinding box 11 is connected to the interior of the box body 1 through the guide plate 24.

[0030] In the above structure, the secondary crushing rod structure allows the crushed slag powder to be guided into the secondary grinding box 11 through the guide plate 24 during operation, thereby enabling the secondary crushing rod to perform secondary crushing of the slag powder, thus improving the processing effect of the device on the slag powder.

[0031] In a preferred embodiment, the outer wall of the housing 1 is provided with a movable groove, and the inner wall of the movable groove is slidably connected to the outer wall of the screen 9.

[0032] In the above structure, the movable groove structure allows the cam 8 to drive the screen 9 to move in a specific eccentric shape during rotation, thereby increasing the contact area between the screen 9 and the slag powder and improving the screening effect of the screen 9 on the slag powder.

[0033] In a preferred embodiment, the outer wall of the cam 8 abuts against the outer wall of the screen 9, and the bottom of the scraper 20 is slidably connected to the top of the screen 9.

[0034] In the above structure, the screen 9 and scraper 20 are designed so that the device can automatically clean up the residue after the operation is completed by using the scraper 20, thus eliminating the need for the user to manually clean up the residue and improving the user's work efficiency.

[0035] In a preferred embodiment, a partition is fixedly fitted to the inner wall of the box 1, and the included angle between the partition and the inner wall of the box 1 is 135°.

[0036] In the above structure, the partition structure allows the primary crushing rod 5 to block the falling slag powder when crushing it, thereby preventing the slag powder from falling onto the screw 19 and affecting the movement of the scraper 20, causing the scraper 20 to jam, thus ensuring that the operation of the device is not affected.

[0037] In a preferred embodiment, there are two limiting blocks 16, and both limiting blocks 16 are symmetrically distributed along the inner wall of the box 1.

[0038] In the above structure, the two limiting blocks 16 can limit both sides of the screen 9, thereby ensuring that the screen 9 will not tilt during the rotation of the cam 8, thus ensuring that the screen 9 can move smoothly and improving the stability of the screen 9 during the screening process.

[0039] Working principle: After assembling the device, the user can directly feed the slag powder into the housing 1. The two primary crushing rods 5 mesh to crush the slag powder. The crushed slag powder is discharged directly through the bottom of the housing 1. The screen 9 collects the unqualified slag powder. At this time, the user can rotate the cam 8 by operating the motor 7, which pushes the screen 9 and causes the limit block 16 to compress the return spring 18, realizing the reciprocating motion of the screen 9 to screen the slag powder, thereby improving the processing effect of the device. After screening, the user can move the scraper 20 by operating the motor 10 to automatically clean the residue on the screen 9. At the same time, the guide plate 24 guides the residue into the secondary grinding box 11 to achieve the secondary crushing effect, thereby improving the automation of the device and the crushing effect of the slag powder.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
