Description

Technical Field

[0001] The present invention relates to the technical field of concrete waste treatment, and particularly relates to a treatment device for concrete waste and a control method thereof. Background Art

[0002] Concrete waste refers to the waste concrete materials generated during the construction process, mainly including the remaining concrete during the construction process, the waste generated during the demolition of old buildings, and the defective products during the production process of concrete products.

[0003] If concrete waste is not properly treated and directly stacked or landfilled, it will pollute the soil and groundwater. The chemical substances in the concrete may seep into the soil, affecting the soil quality, and then affecting plant growth and the ecosystem. Moreover, the concrete waste contains a large amount of aggregates, sand, cement and other materials. If directly discarded, not only these valuable resources are wasted, but also the treatment and disposal costs are increased. Through recycling, these wastes can be converted into recycled aggregates for manufacturing new concrete materials, thereby reducing the dependence on natural resources.

[0004] Existing concrete waste treatment devices usually only decompose concrete stones. When there is waste metal in the concrete waste, it will damage the treatment device. And during the treatment process, due to the certain toughness of the metal, it is extremely difficult to treat the waste metal, and the stones and metal cannot be screened during the discharging process, resulting in the mixing of stone slag and metal after the waste treatment is completed, which affects the recycling and reuse of the waste. Summary of the Invention

[0005] In view of the deficiencies of the existing technology, the present invention provides the following technical solutions:

[0006] A treatment device for concrete waste, comprising: a device main body, and a jaw crusher is fixedly arranged above the device main body;

[0007] Two groups of cutting rollers symmetrically arranged inside the upper end of the device main body, and the cutting rollers are located directly below the jaw crusher;

[0008] A reciprocating driving mechanism fixedly arranged inside the device main body, the reciprocating driving mechanism has a rack, one end of the rack is fixedly connected to a metal collection box, and the end of the rack away from the metal collection box is fixedly connected to a screen;

[0009] A conveyor belt arranged inside the device main body, and a plurality of strong magnets are fixedly embedded on the surface of the conveyor belt;

[0010] When the reciprocating driving mechanism drives the rack to make a horizontal reciprocating motion, the rack drives the metal collection box and the screen to move synchronously.

[0011] As an improvement of the above technical solution, the reciprocating driving mechanism further includes a servo motor, a turntable, a bump and a swing arm. The servo motor is fixedly arranged on the inner wall surface of the device main body. The turntable is fixedly connected to the output shaft of the servo motor. The bump is fixedly arranged on the surface of the turntable away from the servo motor. The swing arm is movably arranged inside the device main body through a rotating shaft. A strip-shaped groove is formed on the surface of the swing arm. The bump is inserted into the strip-shaped groove. The bottom of the swing arm has fan-shaped teeth, and the swing arm meshes with the rack above the rack.

[0012] As an improvement of the above technical solution, a waste collection box is arranged inside the device main body, and the sieve is movably inserted into the waste collection box through a slot.

[0013] As an improvement of the above technical solution, the reciprocating driving mechanism is located below the conveyor belt and between the metal collection box and the waste collection box.

[0014] As an improvement of the above technical solution, a scraper is arranged on the side surface of the metal collection box. The upper surface of the scraper is attached to the bottom of the conveyor belt, and the metal collection box is horizontally higher than the waste collection box.

[0015] As an improvement of the above technical solution, strip-shaped protrusions are arranged on both sides of the metal collection box and the waste collection box. The metal collection box and the waste collection box are both slidably arranged on the bottom of the device main body through the strip-shaped protrusions, and the metal collection box and the waste collection box are respectively located at both ends below the conveyor belt.

[0016] As an improvement of the above technical solution, a plurality of cutting blades are arranged on the surfaces of the two groups of cutting rollers, and the two groups of cutting rollers are symmetrically arranged in a manner that the cutting blades are mutually offset.

[0017] As an improvement of the above technical solution, a plurality of strong suction magnets are embedded on the surface of the conveyor belt in an equidistant arrangement, and the conveyor belt and the strong suction magnets are at the same level.

[0018] As an improvement of the above technical solution, a feed inlet is opened at the connection between the device main body and the jaw crusher, and the feed inlet is located directly above the cutting rollers.

[0019] As an improvement of the above technical solution, the following steps are included:

[0020] S1: After putting the concrete waste into the jaw crusher for preliminary crushing work, it then falls through the feed inlet between the two groups of cutting rollers for secondary treatment, and the two groups of cutting rollers cut the metal doped in the concrete waste.

[0021] S2: After the concrete waste has undergone secondary treatment by the cutting rollers, the cut small-sized concrete waste fragments and metal slag will fall onto the surface of the conveyor belt. The metal slag is adsorbed by the strong magnetic magnets embedded on the surface of the conveyor belt. When the concrete waste fragments and metal slag are conveyed to the end of the conveyor belt, the concrete waste fragments will fall into the waste collection box due to gravity, while the metal slag will be adsorbed by the strong magnetic magnets and continue to be conveyed;

[0022] S3: When the reciprocating drive mechanism is working, the servo motor drives the turntable to rotate, so that the convex block drives the swing arm to start making a reciprocating swinging motion. The reciprocating swinging motion of the swing arm will drive the rack to make a horizontal reciprocating movement, and then drive the metal collection box and the screen to move horizontally synchronously;

[0023] S4: When the concrete waste fragments fall into the waste collection box, they will be blocked by the screen. The concrete waste fragments will perform a screening operation by moving horizontally reciprocally with the screen, sifting the fine powder and dust into the waste collection box, and the larger fragments will be retained on the surface of the screen. When the metal slag continues to be conveyed and the metal collection box makes a horizontal reciprocating movement, the scraper will be driven to scrape the metal slag adsorbed by the strong magnetic magnets into the metal collection box.

[0024] Advantages of the present invention:

[0025] Through the design of the jaw crusher, the concrete waste can be preliminarily processed. The preliminarily processed concrete waste falls between the two groups of cutting rollers for secondary treatment. The two groups of cutting rollers arranged in a staggered manner can effectively cut the waste metal existing in the concrete waste, avoiding large metals from entering the device and causing damage to it. Through the design of the conveyor belt, the processed concrete waste fragments and metal slag can be conveyed into the waste collection box and the metal collection box. The strong magnetic magnets can adsorb the metal slag, avoiding the mixing of concrete waste fragments and metal slag and affecting the subsequent recycling work. The design of the reciprocating drive mechanism can control the screen and the metal collection box at the same time. When screening the waste stone slag, it can also scrape off the metal slag adsorbed by the strong magnetic magnets, quickly and effectively performing the screening of the stone slag and metal.

The present invention can also be implemented or applied through other different specific implementation modes. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0032] Existing concrete waste treatment devices usually only decompose concrete stones. When there is waste metal in the concrete waste, it will damage the treatment device. Moreover, during the treatment process, due to the certain toughness of the metal, it is extremely difficult to treat the waste metal, and the stones and metal cannot be screened during the discharging process, resulting in the mixture of stone slag and metal after the waste treatment is completed, which affects the recycling and reuse of the waste.

[0033] To solve this problem, please refer to Figures 1-4 , a treatment device for concrete waste, comprising: a device main body 1, and a jaw crusher 2 is fixedly arranged above the device main body 1;

[0034] Two groups of cutting rollers 3 symmetrically arranged inside the upper end of the device main body 1, and the cutting rollers 3 are located directly below the jaw crusher 2;

[0035] A reciprocating drive mechanism 4 fixedly arranged inside the device main body 1, the rack 401 of the reciprocating drive mechanism 4, one end of the rack 401 is fixedly connected to a metal collection box 5, and the end of the rack 401 away from the metal collection box 5 is fixedly connected to a screen 601;

[0036] A conveyor belt 7 arranged inside the device main body 1, and a plurality of strong suction magnets 701 are fixedly embedded on the surface of the conveyor belt 7;

[0037] When the reciprocating drive mechanism 4 drives the rack 401 to perform a horizontal reciprocating motion, the rack 401 drives the metal collection box 5 and the screen 601 to move synchronously.

[0038] During use, the concrete waste is put into the jaw crusher 2 for preliminary crushing work, and then undergoes secondary treatment through two groups of cutting rollers 3. The two groups of cutting rollers 3 perform cutting work on the metal mixed in the concrete waste. When the concrete waste undergoes the secondary treatment by the cutting rollers 3, the cut small-sized concrete waste fragments and metal slag will fall onto the surface of the conveyor belt 7, and the metal slag is adsorbed by the strong magnet 701 embedded on the surface of the conveyor belt 7. When the concrete waste fragments and metal slag are conveyed to the end of the conveyor belt 7, the concrete waste fragments fall into the waste collection box 6 due to gravity, while the metal slag is adsorbed by the strong magnet 701 and continues to be conveyed. When the reciprocating drive mechanism 4 operates, the servo motor 402 drives the turntable 403 to rotate, so that the bump 404 drives the swing arm 405 to start performing reciprocating swinging motion. The reciprocating swinging motion of the swing arm 405 drives the rack 401 to perform horizontal reciprocating movement, and then drives the metal collection box 5 and the screen 601 to move horizontally synchronously.

[0039] In one embodiment, please refer to Figures 3-4 , the reciprocating drive mechanism 4 further includes a servo motor 402, a turntable 403, a bump 404 and a swing arm 405.

The bottom of the swing arm 405 has fan-shaped teeth, and the swing arm 405 meshes with the rack 401 above it.

[0040] During use, the servo motor 402 drives the turntable 403 to rotate, so that the bump 404 drives the swing arm 405 to start performing reciprocating swinging motion. The reciprocating swinging motion of the swing arm 405 drives the rack 401 to perform horizontal reciprocating movement, and then drives the metal collection box 5 and the screen 601 to move horizontally synchronously.

[0043] In one embodiment, please refer to Figures 2-3, the reciprocating drive mechanism 4 is located below the conveyor belt 7, and the reciprocating drive mechanism 4 is located between the metal collection box 5 and the waste collection box 6.

[0044] During use, the metal collection box 5 and the waste collection box 6 are located below the conveyor belt 7, which can better collect the concrete waste stone slag and metal scraps. The reciprocating drive mechanism 4 between the metal collection box 5 and the waste collection box 6 can more efficiently drive and control the two.

[0045] In one embodiment, please refer to Figures 2-3 , a scraper 501 is provided on the side of the metal collection box 5. The upper surface of the scraper 501 is attached to the bottom of the conveyor belt 7, and the metal collection box 5 is horizontally higher than the waste collection box 6.

[0046] During use, when the metal scraps continue to be conveyed, when the metal collection box 5 makes a horizontal reciprocating movement, the scraper 501 will be driven to scrape the metal scraps adsorbed by the strong magnet 701 into the metal collection box 5.

[0047] In one embodiment, please refer to Figures 2-3 , both sides of the metal collection box 5 and the waste collection box 6 have strip-shaped protrusions. The metal collection box 5 and the waste collection box 6 are both slidably arranged at the bottom of the device main body 1 through the strip-shaped protrusions. The metal collection box 5 and the waste collection box 6 are respectively located at both ends below the conveyor belt 7.

[0048] During use, the metal collection box 5 and the waste collection box 6 can separately collect the concrete waste stone slag and the waste metal scraps, avoiding the mixture of the concrete waste stone slag and the waste metal scraps from affecting the subsequent recycling and reuse.

[0049] In one embodiment, please refer to Figure 2 , a plurality of cutting blades 301 are provided on the surfaces of the two groups of cutting rollers 3. The two groups of cutting rollers 3 are symmetrically arranged in a way that the cutting blades 301 are mutually offset.

When the concrete waste fragments and metal slag are conveyed to the end of the conveyor belt 7, the concrete waste fragments fall into the waste collection box 6 due to gravity, while the metal slag continues to be adsorbed by the strong magnet 701 and is conveyed further;

[0058] S3: When the reciprocating drive mechanism 4 operates, the servo motor 402 drives the turntable 403 to rotate, so that the convex block 404 drives the swing arm 405 to start reciprocating swing movement.
