Description

Technical Field

[0001] The invention relates to the technical field of waste concrete recycling, in particular to a waste concrete preparation system. Background Art

[0002] Concrete refers to a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. Waste materials are generated during the preparation of concrete, and most of these waste materials can be recycled. The waste concrete is crushed, screened, and cleaned by a crusher as recycled aggregate to avoid waste of resources. For example, a waste treatment device for concrete production disclosed in the prior art has an application number (202320597995.9). The patent can guide the dust-containing gas in the protective cover through the exhaust fan inside the protective cover, and then discharge it after being filtered by the filter bag, effectively preventing the dust generated during crushing from spreading;

[0003] However, this patent does not transport the waste concrete evenly during crushing, causing uneven wear of the crushing rollers inside the crushing device, affecting the subsequent crushing effect. It does not grind the waste concrete more finely, which easily leaves residual particles, affecting the quality of subsequent concrete aggregates. Therefore, in order to avoid the above technical problems, we need to provide a waste concrete preparation system to overcome the above defects in the prior art. Summary of the invention

Then, because the cross bar continuously drives the inner cylinder to rotate, the storage tank filled with waste concrete rotates away, and during the rotation process, the arc block loses the support of the arc ring, and then the support spring pushes the extrusion plate to move, so as to extrude and level the waste concrete inside the storage tank;

[0024] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0025] 1. A flat conveying mechanism is provided, which drives the rotating shaft and the conveyor belt to rotate through the driving motor, and drives the transmission gear and the positioning rod to rotate, and then transmits the power through the transmission wheel and the crawler belt, drives the cross bar and the inner cylinder to rotate inside the conveying cylinder, so that the storage tank moves to the bottom of the feed hopper, which is convenient for the waste concrete inside the feed hopper to enter the storage tank, and then because the cross bar continuously drives the inner cylinder to rotate, the storage tank filled with waste concrete continues to rotate and leaves the bottom of the feed hopper. At the same time, during the rotation of the inner cylinder, the arc block loses the support of the arc ring, so that the support spring pushes the extrusion plate to move, and the waste concrete inside the storage tank is squeezed and flattened, forcing the waste concrete to be evenly distributed between the extrusion plate and the conveying cylinder, and then evenly transported to the conveyor belt through the discharge hopper. At the same time, because four storage tanks are opened on the outside of the inner cylinder, the waste concrete can be continuously and intermittently transported, which ensures the transportation efficiency. At the same time, too much is transported at one time, which affects the subsequent grinding effect;

[0026] In addition, the driven gear is driven to rotate through the transmission gear. At the same time, because the traction plates are staggered up and down on the two driven gears, one driven gear pulls the traction block to slide to one side through the traction plate, and the other driven gear pushes the traction block to slide to the other side through the traction plate. Then the swing plate and the scraper are pulled by the traction cable to slide back and forth inside the cross frame to spread the waste concrete on the conveyor belt. The baffle plate is used to block and cooperate to further spread the waste concrete evenly on the conveyor belt to prevent it from piling up, so that the waste concrete can evenly enter the crushing box to prevent uneven wear of the crushing roller.

[0027] 2. A crushing and regulating mechanism is set up. The waste concrete that is conveyed and filtered is guided to the space between the two crushing rollers through the guide plate. Then the double-axis motor is started to drive the transmission rod to rotate, and the driving gear is driven to rotate through the gear ring. At the same time, the sleeve and the connecting rod are combined to form a connecting rod, which is convenient for transmitting power, driving the turntable, the rotating rod and the crushing roller to rotate, crushing the waste concrete that enters the crushing box, and facilitating the subsequent preparation of the waste concrete into new concrete filling aggregate;

[0028] In addition, the swing arm is driven to rotate by the transmission rod, and the screening frame and the movable rod are pulled up and down by the cooperation of the rotating plate, which improves the screening effect, so that the waste concrete with larger particles is blocked and then falls into the recycling box, which is convenient for collection and re-crushing, while the waste concrete that passes through the screening frame is stored in the collection box for subsequent preparation into aggregate;

[0029] In addition, by rotating the top rod to move the tooth plate, the tooth plate is separated from the tooth groove, the limit between the sleeve and the connecting rod is released, and the connecting rod is convenient for sliding. Then the push rod is rotated to move the slide plate along the rectangular groove, and the distance between the two crushing rollers is changed as needed, which facilitates the adjustment of the crushing effect and improves adaptability.

[0030] In summary, the crushed waste concrete is evenly spread through the paving and conveying mechanism to prevent the waste concrete from piling up, and then when the waste concrete is crushed by the crushing and regulating mechanism, it is prevented from concentration and blockage, and at the same time, the uniformity of the internal crushing roller wear is improved, the crushing effect is guaranteed, the waste concrete is ground more finely, and the quality of the aggregate is guaranteed.

[0056] The working principle and use process of the present invention are as follows: first, the waste concrete is fed into the jaw crusher 3 for crushing, so that the large pieces of waste concrete are crushed into uniform small pieces, and then discharged into the feed hopper 403 through the discharge channel 404. At the same time, the driving motor 433 drives the rotating shaft 416 and the conveyor belt 417 to rotate, forcing the rotating shaft 416 at the other end of the conveyor frame 2 to rotate, and the power is transmitted by the cooperation of the transmission gear 419, driving the positioning rod 418 to rotate, and then the driving wheel 420 and the crawler 421 cooperate to drive the driving wheel 420 and the crawler 421 to rotate again. The force is transmitted to drive the crossbar 405 to rotate, and the crossbar 405 and the inner cylinder 406 are rotated inside the transfer cylinder 402, changing the position of the storage tank 407, so that the storage tank 407 moves to the bottom of the feed hopper 403, releasing the seal of the feed hopper 403, and facilitating the waste concrete inside the feed hopper 403 to enter the storage tank 407. Then, because the crossbar 405 continuously drives the inner cylinder 406 to rotate, the storage tank 407 filled with the waste concrete rotates away from the bottom of the feed hopper 403, and the feed hopper 403 is sealed again;

[0057] In addition, during the process of the inner cylinder 406 rotating with the storage trough 407, the arc block 413 separates from the arc ring 414 as it rotates, thereby releasing the support of the arc ring 414 on the arc block 413, and then the extrusion plate 409 and the slide bar 408 are pushed to move through the telescopic characteristics of the support spring 410 to extrude the waste concrete inside the storage trough 407, forcing the waste concrete to be evenly distributed between the extrusion plate 409 and the transfer cylinder 402. When the inner cylinder 406 rotates with the storage trough 407 filled with waste concrete to the top of the discharge hopper 415, the storage trough 407 loses the obstruction of the transfer cylinder 402, thereby facilitating the waste concrete inside to evenly fall onto the conveyor belt 417 through the discharge hopper 415 to prevent accumulation. The discharged storage trough 407 moves back to the bottom of the feed hopper 403 as the inner cylinder 406 rotates, and this cycle is repeated to continuously and intermittently transport the waste concrete.

[0058] Next, during the process of conveying the waste concrete by the conveying belt 417, the driven gear 422 is driven to rotate through the transmission gear 419, and then the traction block 423 is pulled to slide on both ends of the conveying frame 2 through the cooperation of the traction plate 424. At the same time, because the traction plates 424 are staggered up and down on one end of the two driven gears 422, one driven gear 422 pulls the traction block 423 to slide to one side through the traction plate 424, and the other driven gear 422 pushes the traction block 423 to slide to the other side through the traction plate 424. Then, through the traction cable 427, the swing plate 426 and the scraper 429 are pulled to slide back and forth inside the cross frame 425 to spread the waste concrete on the conveying belt 417. In addition, through the blocking cooperation of the baffle plate 432, the waste concrete is further evenly spread on the conveying belt 417 to prevent it from piling up.

[0059] Next, the paved waste concrete is conveyed to the inside of the crushing box 501 through the conveyor belt 417, and is guided by the guide plate 502 to the two crushing rollers 508 of the conveyor belt. Then, the dual-axis motor 516 is started to drive the transmission rod 517 to rotate, and through the cooperation of the gear ring 518, the driving gear 512 is driven to rotate, and the two adjacent driving gears 512 are made to rotate relative to each other. Then, through the cooperation of the sleeve 513 and the connecting rod 510, a connecting rod is formed to drive the rotating disk 509 to rotate, forcing the rotating disk 509 to push the rotating rod 507 and the crushing roller 508 to rotate, so as to crush the waste concrete entering the crushing box 501, so as to facilitate the subsequent preparation of the waste concrete into new concrete filling aggregate.

[0060] Next, the crushed waste concrete falls on the screening rack 521 for screening, and at the same time, the swing arm 522 is driven to rotate by the transmission rod 517, and the screening rack 521 and the movable rod 520 are pulled to move up and down through the cooperation of the rotating plate 523, thereby improving the screening effect, so that the waste concrete with larger particles is blocked, and then falls into the recovery box 525 through the screening rack 521, which is convenient for collection and re-crushing, while the waste concrete passing through the screening rack 521 is stored in the collection box 524 for subsequent preparation into aggregate;

[0061] Finally, by rotating the top rod 514 to move the tooth plate 515, the tooth plate 515 is separated from the tooth groove 511, and the limit between the sleeve 513 and the connecting rod 510 is released, which facilitates the sliding of the connecting rod 510. Then, the push rod 505 is rotated to move the slide plate 506 along the rectangular groove 503, and the distance between the two crushing rollers 508 is changed as needed, which facilitates the adjustment of the crushing effect and improves the adaptability. In addition, the top rod 514 is rotated to push the tooth plate 515 to move, embed it into the tooth groove 511, and limit the connecting rod 510 again, so that the connecting rod 510 and the sleeve 513 form a connecting rod to maintain the transmission of power.

[0062] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
