[0018] The first aspect of this utility model proposes a steel slag waste recycling and pressing mechanism, such as... Figure 1-8 As shown, it includes: a base 1, a pressing mold 2 fixedly installed on the base 1, and a pressing plate 301 slidably installed inside the pressing mold 2. A hydraulic cylinder 3 is fixedly connected to one end of the pressing plate 301, and the bottom of the hydraulic cylinder 3 is fixedly installed on the base 1. A conveyor 4 is fixedly installed on the top of the pressing mold 2. It should be noted that a conical storage tank is fixed on the top of the pressing mold 2 for storing steel slag. A spiral conveying rod is installed in the storage tank by a motor to facilitate the conveying of steel slag into the interior of the pressing mold 2. A discharge port 201 is opened through one end of the pressing mold 2. A sealing mechanism 5 is provided on one side of the top of the pressing plate 301 to automatically seal the discharge port 201. A pushing component 6 is provided on the other side of the top of the pressing plate 301 to automatically push out the steel slag after pressing. The material pushing assembly 6 includes: a push rod 601, which is movably installed inside the discharge port 201. One end of the push rod 601 is fitted with a guide sleeve 602, and the guide sleeve 602 is fixedly installed on the surface of the pressing mold 2. A hinge rod 603 is hingedly installed at the end of the push rod 601, and a second movable plate 604 is hingedly installed at one end of the hinge rod 603. The second movable plate 604 is slidably installed on one side of the top of the pressing mold 2, and the bottom of the second movable plate 604 is fixedly installed on the other side of the top of the pressure plate 301.

[0019] As the pressure plate 301 approaches the discharge port 201, the second movable plate 604 on the pressure plate 301 moves towards the discharge port 201, causing the hinge rod 603 at the top of the second movable plate 604 to push the hinged push rod 601 from one end of the discharge port 201 to the other end. After the pressure plate 301 completes the pressing of the steel slag into a cake, when the pressure plate 301 drives the second movable plate 604 to reset, the hinge rod 603 again drives the hinged push rod 601 to move into the discharge port 201, so that the push rod 601 automatically pushes the cake-shaped steel slag out of the discharge port 201, reducing manual operation and further improving work efficiency.

[0020] In this embodiment, the sealing mechanism 5 includes: a first movable plate 501, which is slidably installed on the other side of the top of the pressing mold 2. The bottom of the first movable plate 501 is fixedly connected to one side of the top of the pressing plate 301. A trapezoidal guide groove 5011 is provided on the surface of the first movable plate 501, and a baffle 502 is movably installed on the trapezoidal guide groove 5011. Slider 503 is fixedly connected to both sides of the baffle 502. A sliding groove 504 is symmetrically provided on one side of the pressing mold 2 near the discharge port 201. The slider 503 is slidably installed in the corresponding sliding groove 504. A guide rod 505 is vertically installed inside the sliding groove 504 and passes through the inside of the slider 503. A first spring 506 is fitted on the surface of the guide rod 505, and the two ends of the first spring 506 are respectively fixedly installed between the bottom of the slider 503 and the bottom of the sliding groove 504. A telescopic component 507 is provided between the top of the baffle 502 and the trapezoidal guide groove 5011.

[0021] In the pressing of steel slag waste, the steel slag is conveyed to the inside of the pressing mold 2 by the conveyor 4, and then the output end of the hydraulic cylinder 3 pushes the pressing plate 301 to move inside the pressing mold 2, pushing the steel slag towards the discharge port 201. At this time, the top of the pressing plate 301 drives the first movable plate 501 to move, so that the telescopic component 507, which is movably installed in the trapezoidal guide groove 5011 on the surface of the first movable plate 501, moves downward along the inclined groove direction of the trapezoidal guide groove 5011. At the same time, the slider 503 on the baffle 502 squeezes the first spring 506 to compress, so that the telescopic component 507 drives the baffle 502 to descend. After the baffle 502 descends to the position, the telescopic component 507 moves horizontally at the bottom of the trapezoidal guide groove 5011. At this time, the baffle 502 blocks one end of the discharge port 201, and the other end of the discharge port 201 is reset by the movement of the push rod 601, blocking the other end. The pressing plate 301 also blocks the pushed steel slag. The slag moves towards the inner wall of the pressing mold 2 for compression, pressing the steel slag into a cake shape. At the same time, the telescopic component 507 at the top of the baffle 502 moves to its limit position at the bottom of the trapezoidal guide groove 5011. At this time, the first spring 506 elastically resets, pushing the slider 503 upward, causing the baffle 502 to move the telescopic component 507 to the upper end of the trapezoidal guide groove 5011, so that the baffle 502 is in an open state. This realizes the automatic opening and closing of the baffle 502, which avoids the cake material from dispersing during the steel slag pressing process, improves the cake forming rate, and facilitates the ejection of the cake material after pressing. Then, the hydraulic cylinder 3 drives the pressing plate 301 to move and reset, thereby driving the first movable plate 501 to reset. At this time, the telescopic component 507 moves horizontally at the upper end of the trapezoidal guide groove 5011. When the pressing plate 301 resets, the pushing component 6 pushes the cake-shaped steel slag out of the discharge port 201 and falls onto the feeding plate 7 for collection.

[0022] In this embodiment, the slider 503 has a T-shaped structure, and the groove 504 is a T-shaped groove that cooperates with the slider 503. Since both the slider 503 and the groove 504 are T-shaped, after the baffle 502 blocks one end of the discharge port 201, when the slag is being compressed, the compressed slag is prevented from being squeezed out of the baffle 502 and thus improving the stability of the baffle 502's sealing.

[0023] In this embodiment, the telescopic component 507 includes a guide pin 5071, which is movably disposed through the top of the baffle 502. One end of the guide pin 5071 extends into the trapezoidal guide groove 5011. A fixing ring 5072 is fixedly connected to the surface of the guide pin 5071. A second spring 5073 is fitted in the middle of the guide pin 5071, and the two ends of the second spring 5073 are respectively fixedly installed between the surface of the fixing ring 5072 and the surface of one side of the baffle 502.

[0024] In this embodiment, a limiting block 50111 is fixedly connected to one side of the upper end of the trapezoidal guide groove 5011, and the limiting block 50111 is located on one side of the guide pin 5071. When the guide pin 5071 moves to the side away from the hydraulic cylinder 3, the limiting block 50111 restricts the horizontal movement of the guide pin 5071, so that the guide pin 5071 can only move downward along the inclined groove.

[0025] In this embodiment: the surface of the limiting block 50111 is set as an inclined surface, and one end of the guide pin 5071 is set as an arc surface that cooperates with the inclined surface of the limiting block 50111.

[0026] After the guide pin 5071 is about to return to its original position, the arc surface of one end of the guide pin 5071 presses against the inclined surface of the limiting block 50111, causing the guide pin 5071 to move and retract towards the baffle 502. The second spring 5073 is also compressed. When the guide pin 5071 releases the compression from the limiting block 50111, the second spring 5073 elastically returns to its original position, pushing the guide pin 5071 to move into the trapezoidal guide groove 5011. This ensures that the second spring 5073 remains against the inside of the trapezoidal guide groove 5011, facilitating the movement of the baffle 502 along the trapezoidal guide groove 5011.

[0027] In this embodiment, a feeding plate 7 is fixedly connected to one side of the pressing mold 2 and below the baffle 502, and the feeding plate 7 is inclined. By placing a receiving box below the feeding plate 7, it is convenient to guide the ejected cake into the receiving box for collection.

[0028] In this embodiment, a plurality of balls are fixedly installed at equal intervals along the circumference of the inner wall of the guide sleeve 602, and one side of each ball rests on the surface of the push rod 601. By using the balls, the contact area between the guide sleeve 602 and the push rod 601 is reduced, friction is decreased, and the stability of the push rod 601 movement is improved.

[0029] Working principle: In the pressing of steel slag waste, the steel slag is conveyed to the inside of the pressing mold 2 by the conveyor 4. Then, the output end of the hydraulic cylinder 3 pushes the pressing plate 301 to move inside the pressing mold 2, pushing the steel slag towards the discharge port 201. At this time, the top of the pressing plate 301 drives the first movable plate 501 to move, so that the telescopic component 507, which is movably installed in the trapezoidal guide groove 5011 on the surface of the first movable plate 501, moves downward along the inclined groove direction of the trapezoidal guide groove 5011. At the same time, the slider 503 on the baffle 502 squeezes the first spring 506 to compress, so that the telescopic component 507 drives the baffle 502 to descend. After the baffle 502 descends to the position, the telescopic component 507 moves horizontally at the bottom of the trapezoidal guide groove 5011. At this time, the baffle 502 blocks one end of the discharge port 201, while the other end of the discharge port 201 is blocked by the push rod 601. The pressure plate 301 moves towards the inner wall of the pressing mold 2 to squeeze the steel slag into a cake shape. When the pressure plate 301 moves towards the discharge port 201, the second movable plate 604 on the pressure plate 301 moves towards the discharge port 201. This causes the hinge rod 603 at the top of the second movable plate 604 to push the hinged push rod 601 from one end of the discharge port 201 to the other end, facilitating the pressing plate 301 to perform the cake pressing operation. At the same time, the telescopic component 507 at the top of the baffle 502 moves to the limit position at the bottom of the trapezoidal guide groove 5011. At this time, the first spring 506 elastically resets, pushing the slider 503 to rise, causing the baffle 502 to move the telescopic component 507 to the upper end of the trapezoidal guide groove 5011, so that the baffle 502 is in an open state. After the pressure plate 301 completes the pressing of the steel slag into a cake, the hydraulic cylinder 3 drives the pressure plate 301 to move and reset, thereby driving the first movable plate 501 to reset. At this time, the telescopic component 507 moves horizontally at the upper end of the trapezoidal guide groove 5011. When the pressure plate 301 drives the second movable plate 604 to reset, the hinge rod 603 drives the hinged push rod 601 to move into the discharge port 201 again, so that the push rod 601 automatically pushes the cake-shaped steel slag out of the discharge port 201 and falls onto the feeding plate 7 for collection.
