Description

Technical Field

[0001] The utility model relates to the technical field of shield machines, and more specifically to a concrete recycling and separation device. Background Art

[0002] The shield machine segment refers to the annular concrete component used in the construction process of the shield machine. The shield machine segment is mainly composed of concrete and steel bars. During the production process of the shield machine segment, a certain amount of concrete waste needs to be processed and recycled. Therefore, concrete recycling and separation equipment is needed to separate the concrete crushed stone and steel bars in the concrete waste. By recycling concrete crushed stone and steel bars, the procurement cost of new materials can be reduced, which is economically beneficial for segment manufacturers.

[0003] Chinese Patent Authorization Announcement No.: CN219483738U provides a recycling and separation device based on concrete residue. This solution sets an inclined discharging ramp under the crushing roller, and can use the slope to discharge the crushed concrete fragments to one side. By setting a magnetic iron rod through the discharging ramp, the passing steel bars can be sucked, thereby realizing the rapid recovery and separation of the steel bars. The discharging ramp is flipped by the winch structure, so that the steel bars can be separated from the adsorption of the iron rod and slide out to the other side, achieving the effect of classified discharge of steel bars and concrete fragments.

[0004] This solution uses a pair of crushing rollers to crush concrete waste, and then uses magnets to separate crushed stone and steel bars. However, some concrete crushed stone and dust will still remain on the surface of the steel bars after separation, which increases the difficulty of subsequent processing and handling of the steel bars. It may take more time and labor to clean the surface, increasing production costs and workload. Therefore, a concrete recycling and separation equipment is proposed to address the above problems.

[0036] Example:

[0037] See also Figure 1 A concrete recycling and separation device comprises a shell 1, a top of the shell 1 is fixedly connected with a feed hopper 2 connected with an inner cavity, and a pair of crushing rollers 3 are installed on the inner wall of the shell 1, and the pair of crushing rollers 3 are located directly below the feed hopper 2, and a pair of mutually symmetrical first guide plates 4 are fixedly connected to the inner wall of the shell 1, the first guide plates 4 are inclined, and a separation component 5 is arranged on the lower side of the first guide plate 4, the separation component 5 comprises a pair of mutually symmetrical impact plates 503, and an electromagnet 504 is installed at one end of the pair of impact plates 503 away from each other, and a cleaning component 8 is arranged on the lower side of the separation component 5, and the cleaning component 8 comprises a cleaning box 801, the cleaning box 801 is slidably connected to the inner wall of the shell 1, and a feed port 803 is opened at the upper end of the cleaning box 801, and a pair of mutually symmetrical wire rollers 804 are installed on the inner wall of the cleaning box 801, and the pair of wire rollers 804 are located directly below the feed port 803.

[0038] The shield machine segment refers to the annular concrete component used in the shield machine construction process. The shield machine segment is mainly composed of concrete and steel bars. In the production process of the shield machine segment, a certain amount of concrete waste needs to be processed and recycled. Therefore, it is necessary to invest in concrete recycling and separation equipment to separate the concrete crushed stone and steel bars in the concrete waste. In this solution, the user can put the concrete waste from the feed hopper 2 into the inner cavity of the shell 1, and then fall into a pair of crushing rollers 3. The pair of crushing rollers 3 rotate synchronously in opposite directions to crush the waste (the pair of crushing rollers 3 are driven by a servo motor and a gear). Drive, which is the prior art), and at the same time, the user starts a pair of electromagnets 504. The magnetic field generated by the electromagnets 504 will affect the pair of impact plates 503 in contact with them, so that the impact plates 503 have temporary strong magnetism. With the rolling of the pair of crushing rollers 3, the waste is crushed, and the steel bars and gravel in the waste are initially separated and fall from between the pair of impact plates 503. The gravel falls directly through the impact plates 503, while the steel bars are adsorbed on the pair of impact plates 503. The setting of a pair of first guide plates 4 can guide the separated gravel and steel bars, so that they can fall smoothly between the pair of impact plates 503.

[0039] See also Figure 1-3 The separation component 5 also includes a pair of mutually symmetrical first electric push rods 501, which are installed on the inner wall of the shell 1, and the output end of the first electric push rod 501 is fixedly connected to the limit plate 502, and a pair of impact plates 503 are fixedly connected to the limit rod 505 at one end away from each other, the limit rod 505 is slidably connected to the limit plate 502, and the outer end of the limit rod 505 is sleeved with a spring 506, and the two ends of the spring 506 are respectively fixedly connected to the limit plate 502 and the impact plate 503.

[0040] The falling gravel falls onto the second guide plate 802, slides along the second guide plate 802 to the gravel collection box 6 for collection. Some gravel remains on the surface of the steel bar adsorbed on the impact plate 503 and needs to be further processed. At this time, the user starts a pair of first electric push rods 501 to push repeatedly simultaneously, driving a pair of limit plates 502 to move in a direction close to each other, thereby forcing a pair of impact plates 503 to collide with each other. During the collision, the impact plate 503 drives the limit rod 505 to slide on the limit plate 502 and squeezes the spring 506. With multiple collisions, the gravel on the surface of the steel bar can be further crushed, and the fallen gravel will continue to fall onto the second guide plate 802 and slide into the gravel collection box 6.

[0041] See also Figure 1 and 4A second electric push rod 7 is installed at the bottom end of the inner wall of the shell 1, and the output end of the second electric push rod 7 is fixedly connected to the cleaning box 801. One end of the cleaning box 801 is fixedly connected to the second guide plate 802, and the second guide plate 802 is inclined. A gravel collection box 6 is arranged at the bottom end of the inner wall of the shell 1. The gravel collection box 6 is located directly below the lower end of the second guide plate 802. The outer end of the wire roller 804 is fixedly connected with tightly arranged steel wires. The bottom end of the inner wall of the cleaning box 801 is inclined, and a feeding port 808 is opened at the end of the cleaning box 801 away from the second guide plate 802.

[0042] After the residual gravel on the surface of the steel bar is impacted and crushed, the user starts the second electric push rod 7 to shrink, driving the cleaning box 801 to slide on the inner wall of the shell 1, so that the pair of wire rollers 804 come to the bottom of the pair of impact plates 503, and start the pair of wire rollers 804 to rotate synchronously in opposite directions (the wire rollers 804 are driven by servo motors and gears, which is the prior art). Then the user turns off the pair of electromagnets 504 to make the impact plate 503 lose its magnetism, and the steel bar on the impact plate 503 falls off and falls between the pair of wire rollers 804. As the wire rollers 804 rotate, the steel bar is scraped by the steel wire on the surface of the wire rollers 804, which can remove the debris stuck on the surface of the steel bar. Then the steel bar falls into the inner cavity of the cleaning box 801 and slides down along the bottom end of the inner wall of the cleaning box 801.

[0043] A water tank 805 is installed at the top of the cleaning box 801, and a plurality of high-pressure nozzles 806 are installed at the top of the inner wall of the cleaning box 801. The plurality of high-pressure nozzles 806 are all connected to the inner cavity of the water tank 805, and a plurality of water filtering holes 807 are opened at the bottom of the inner wall of the cleaning box 801.

[0044] The user can fill the water for flushing in the water tank 805 in advance. When the steel bars fall, multiple high-pressure nozzles 806 are simultaneously started to extract water from the water tank 805 and spray the water onto the steel bars to flush the steel bars and thoroughly clean the dust on the surface of the steel bars. After cleaning, the steel bars finally fall out through the discharge port 808. The setting of the water filter hole 807 can help to quickly discharge the sewage in the inner cavity of the cleaning box 801.

[0045] Working principle:

[0046] When separating and recycling concrete waste, the user puts the concrete waste from the feed hopper 2 into the inner cavity of the shell 1, and then falls between a pair of crushing rollers 3. The pair of crushing rollers 3 rotate synchronously in opposite directions to crush the waste (the pair of crushing rollers 3 are driven by a servo motor and gears, which is a prior art). At the same time, the user starts a pair of electromagnets 504. The magnetic field generated by the electromagnets 504 will affect the pair of impact plates 503 in contact with them, so that the impact plates 503 have temporary strong magnetism. With the rolling of the pair of crushing rollers 3, the waste is crushed, and the steel bars and gravel in the waste are preliminarily separated and are all from between the pair of impact plates 503. The crushed stones fall directly through the impact plate 503 onto the second guide plate 802, and slide along the second guide plate 802 to the crushed stone collection box 6 for collection, while the steel bars are adsorbed on the pair of impact plates 503. The user starts the pair of first electric push rods 501 to push repeatedly, driving the pair of limit plates 502 to move in the direction of approaching each other, thereby forcing the pair of impact plates 503 to collide with each other. During the collision, the impact plate 503 drives the limit rod 505 to slide on the limit plate 502 and squeezes the spring 506. With multiple collisions, the crushed stones on the surface of the steel bars can be further crushed, and the fallen crushed stones will The cleaning box 801 is driven by the second electric push rod 7 to slide on the inner wall of the shell 1, so that the pair of steel wire rollers 804 come to the right below the pair of impact plates 503, and start the pair of steel wire rollers 804 to rotate synchronously in opposite directions (the pair of steel wire rollers 804 are driven by a servo motor and gears, which is the prior art). Then, the user turns off the pair of electromagnets 504 to make the impact plate 503 lose its magnetism, and the steel bars on the impact plate 503 fall off and fall between the pair of steel wire rollers 804. As the wire roller 804 rotates, the steel wire on the surface of the wire roller 804 scrapes away the debris adhered to the surface of the steel bar, and then the steel bar falls into the inner cavity of the cleaning box 801 and slides down along the bottom of the inner wall of the cleaning box 801. The user can fill the water for flushing in the water tank 805 in advance. During the falling process of the steel bar, multiple high-pressure nozzles 806 are synchronously started to extract water from the water tank 805 and spray the water onto the steel bar to flush the steel bar and thoroughly clean the dust on the surface of the steel bar. After being cleaned, the steel bar finally falls out through the discharge port 808. The setting of the water filter hole 807 can help to quickly discharge the sewage in the inner cavity of the cleaning box 801.
