Detailed Implementation
[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0029] like Figure 1-4 As shown, a multifunctional steel slag recycling device includes a crushing chamber 1 with a feed inlet at the top and crushing rollers 21 symmetrically rotated within the feed inlet. It also includes symmetrically arranged grinding plates 25 and a grinding table 12 fixedly installed within the crushing chamber 1.
[0030] During its movement, the grinding plate 25 moves relative to the grinding table 12 in the following two directions;
[0031] The grinding plate 25 moves closer to the grinding table 12;
[0032] The grinding plate 25 moves up and down relative to the grinding table 12.
[0033] The steel slag is initially crushed by using two crushing rollers 21 rotating in opposite directions. Then, it is further crushed by using grinding plates 25 and grinding tables 12 symmetrically arranged below the crushing rollers 21. The grinding plates 25 are brought close to the grinding tables 12 to squeeze and crush the steel slag. Then, the grinding plates 25 are moved up and down relative to the grinding tables 12 to further crush the steel slag, thereby improving the crushing effect of the steel slag.
[0034] Specifically, a main motor 2 is symmetrically fixedly installed on the crushing chamber 1, and the output end of the main motor 2 is fixedly installed on one end of the shaft of the crushing roller 21.
[0035] As a further technical solution provided by this utility model, the grinding plates 25 are symmetrically arranged on opposite sides of the grinding table 12, and the two grinding plates 25 move towards the grinding table 12 simultaneously.
[0036] The two grinding plates 25 move up and down synchronously relative to the grinding table 12.
[0037] Specifically, by having two grinding plates 25 simultaneously move closer to the grinding table 12 or move up and down relative to the grinding table 12 in a synchronous manner, the forces exerted by the two grinding plates 25 on the grinding table 12 when they squeeze the steel slag can partially offset each other, thereby reducing the deformation of the grinding table 12 caused by excessive pressure on one side of the grinding table 12.
[0038] Furthermore, a plurality of first grinding protrusions 13 are fixedly installed on the outer wall of the grinding plate 25 on one side of the grinding table 12, and second grinding protrusions 26 are fixedly installed on the outer walls of the grinding table 12 on opposite sides.
[0039] Specifically, by utilizing the first grinding protrusion 13 on the grinding plate 25 and the second grinding protrusion 26 on opposite sides of the grinding table 12, the grinding and crushing effect of steel slag can be improved.
[0040] Furthermore, a slide frame 4 is symmetrically slidably arranged inside the crushing chamber 1, and the bottom end of the grinding plate 25 is hinged to the slide frame 4. An mounting plate 22 is fixedly installed on the main shaft of the crushing roller 21, and the top end of the extension rod 24 fixedly installed on the grinding plate 25 is hinged to the eccentric shaft 23 fixedly installed on the mounting plate 22.
[0041] Specifically, when the two crushing rollers 21 rotate synchronously to crush steel slag, the two extension rods 24 move synchronously with the crushing rollers 21. The eccentric shaft 23 simultaneously drives the extension rods 24 to swing and move up and down. Figure 2 As shown, during the rotation of the extension rod 24 with the eccentric shaft 23, the grinding plate 25 is driven to flip and move towards the grinding table 12 and reciprocate in the up and down direction, thereby realizing the extrusion crushing and reciprocating grinding of steel slag.
[0042] Furthermore, multiple guide pillars 16 are fixedly installed inside the crushing chamber 1, and the slide 4 is slidably mounted on the guide pillars 16. Multiple auxiliary rollers 41 rotatably mounted on the slide 4 are movably mounted on the guide pillars 16.
[0043] Specifically, by using the slide 4 to slide on the guide post 16, the stability of the grinding plate 25 moving up and down is improved, while the auxiliary roller 41 is used to reduce the friction during sliding.
[0044] Furthermore, dust suction ports 11 are provided on the inner walls of the feed inlet on both sides of the crushing chamber 1.
[0045] Specifically, the dust generated during pulverization is sucked out using the suction port 11 or an exhaust fan to facilitate subsequent dust removal.
[0046] Furthermore, piston chambers 14 are symmetrically arranged inside the crushing chamber 1, and piston blocks 42 are reciprocally slidably arranged inside the piston chambers 14. A front sealing plate 6 and a rear sealing plate 7 are respectively hinged at the top end of the piston chamber 14 inside the crushing chamber 1, and the front sealing plate 6 and the rear sealing plate 7 alternately flip.
[0047] Specifically, such as Figure 3 As shown, the front sealing plate 6 and the rear sealing plate 7 are respectively rotatably mounted on the fixed shaft 62 symmetrically fixed on the crushing chamber 1. The outer wall of the fixed shaft 62 is fitted with a torsion spring 61. The first end of the torsion spring 61 is fixedly mounted on the front sealing plate 6 and the rear sealing plate 7 respectively, and the second end of the torsion spring 61 is fixedly mounted on the fixed shaft 62 respectively. The torsion spring 61 keeps the front sealing plate 6 in a vertical state to block the dust suction port 11. At the same time, the torsion spring 61 drives the rear sealing plate 7 to adhere to the baffle 17 set in the crushing chamber 1. Then, as the piston block 42 moves down, it sucks in the dust. At this time, the dust in the feed port of the crushing chamber 1 enters the piston chamber 14 along the front sealing plate 6 that is sucked and flipped. At this time, the rear sealing plate 7 remains in a vertical state. Then, as the piston block 42 moves up, the front sealing plate 6 remains in a vertical state to close the dust suction port 11. At the same time, the rear sealing plate 7 flips to open the piston chamber 14, thereby discharging the sucked dust for further processing.
[0048] Furthermore, the pulverizing chamber 1 is provided with an ash discharge chamber 15 that is connected to the piston chamber 14, and an atomizing nozzle 3 is fixedly installed on the inner wall of the ash discharge chamber 15.
[0049] Specifically, as the piston block 42 moves upward, the front sealing plate 6 remains vertical to close the dust suction port 11, while the rear sealing plate 7 flips to open the piston chamber 14, thereby pushing the sucked dust into the dust discharge chamber 15 by the piston block 42, and then using the atomizing nozzle 3 to absorb and treat the dust.
[0050] Furthermore, a receiving box 8 is provided at the discharge port at the bottom of the crushing chamber 1. A waste liquid tank 81 corresponding to the ash discharge chamber 15 is symmetrically arranged on the receiving box 8, and the receiving box 8 is connected to the waste liquid tank 81.
[0051] Specifically, the receiving box 8 has a connecting port 82 for connecting the waste liquid tank 81 and the receiving box 8. By using the receiving box 8 and the waste liquid tank 81, the steel slag from crushing and grinding and the waste liquid from the dust removal spray from the atomizing nozzle 3 are recycled. At the same time, since the receiving box 8 is connected to the waste liquid tank 81, when the piston block 42 pushes the dust air into the ash discharge chamber 15, the air in the ash discharge chamber 15 flows back into the receiving box 8 for further settling.
[0052] Furthermore, a protective mesh frame 5 is fixedly installed on the dust suction port 11.
[0053] Specifically, the protective mesh frame 5 can prevent slag fragments from splashing into the piston chamber 14.
[0054] Working principle: Two crushing rollers 21 rotate in opposite directions to initially crush the steel slag. Then, two extension rods 24 move synchronously with the crushing rollers 21. An eccentric shaft 23 simultaneously drives the extension rods 24 to swing and move up and down. Figure 2 As shown, during the rotation of the extension rod 24 with the eccentric shaft 23, the grinding plate 25 is driven to flip and approach the grinding table 12 and reciprocate in the up-down direction. This allows the grinding plate 25 to approach the grinding table 12 and compress and crush the steel slag. Then, the reciprocating up-down movement of the grinding plate 25 relative to the grinding table 12 further grinds and crushes the steel slag, thereby improving the crushing effect. Simultaneously, the piston block 42 moves up and down with the grinding plate 25, thereby sucking in dust. During the upward movement of the piston block 42, the sucked-in dust is discharged for further processing.
