Description

Technical Field

[0001] This utility model relates to the field of ready-mixed concrete technology, specifically to a device for strengthening recycled aggregates. Background Technology

[0002] Concrete is a general term for engineering composite materials that bind aggregates together with cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which uses cement as the cementing material, sand and gravel as aggregates, and water in a specific ratio. With increasing emphasis on environmental protection, the recycling and reuse of waste concrete and construction waste such as bricks has become an important issue. Traditional extraction of natural aggregate resources puts significant pressure on the environment. Utilizing waste materials to produce recycled aggregates and reducing the consumption of natural aggregates has become an important direction for improving the green production of concrete.

[0003] Existing technology for recycled aggregate strengthening treatment devices cannot separate and crush concrete waste of different sizes. Larger volume waste will affect the crushing efficiency of smaller volume waste, thus affecting the overall processing efficiency. At the same time, no coating is sprayed on the aggregate after the waste is crushed, resulting in poor bonding strength between the aggregate and cement even after processing, and poor applicability.

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1-5As shown, this utility model provides a device for strengthening recycled aggregate, including two support bases 1. A fixing frame 2 is fixedly installed on the top of each support base 1. A crushing box 5 is fixedly installed at one end of each fixing frame 2. A feed hopper 501 is fixedly installed on the top of the crushing box 5, and mounting seats 500 and feed hopper 502 are fixedly installed on both sides respectively. A crushing mechanism 6 is provided on the top of the mounting seat 500. The crushing mechanism 6 includes two rotating shafts 602, two rotating shafts 607, and a transmission assembly. Crushing rollers 603 and 604 are fixedly sleeved on the outer walls of the two rotating shafts 602 respectively. Crushing rollers 608 and 609 are fixedly sleeved on the outer walls of the two rotating shafts 607 respectively. 09. The transmission assembly can drive two rotating shafts 602 and 607 to rotate. A connecting plate 7 is fixedly installed at one end of the two supporting bases 1. A spraying assembly 8 is provided on the top of the two connecting plates 7, and a fixed base 9 is connected between them. A vibrating screen 10 is fixedly installed on the top of the fixed base 9. The spraying assembly 8 includes a liquid storage tank 803 and an integrated spray head 805. The liquid storage tank 803 has a built-in water pump. The water pump drives the liquid in the liquid storage tank 803 to be sprayed onto the material through the integrated spray head 805. Crushing roller 603 and crushing roller 604 cooperate with each other, crushing roller 608 and crushing roller 609 cooperate with each other, and rotating shafts 602 and 607 are rotatably connected to the crushing box 5.

[0024] The operator first starts motor 601, vibrating screen 10, and water pump. When motor 601 operates, its output drives two rotating shafts 602 and 607 to rotate in opposite directions. Simultaneously, crushing rollers 603 and 604 rotate in opposite directions, as do crushing rollers 608 and 609. Then, whole or large pieces of concrete waste are fed into crushing box 5 from hopper 501, while smaller pieces are fed into crushing box 5 from hopper 2. Crushing rollers 603 and 604 break up the larger pieces of concrete waste, which are then further crushed by crushing rollers 608 and 609. The material fed from hopper 2 is first crushed by crushing rollers 608 and 609, ensuring that large pieces are initially crushed while preventing smaller pieces from being blocked by larger ones, thus effectively improving the crushing efficiency of the concrete waste.

[0025] like Figure 3As shown, in one embodiment, the crushing mechanism 6 further includes a motor 601, which is fixedly mounted on the top of the mounting base 500. The output end of the motor 601 is fixedly connected to one of the rotating shafts 602. The transmission assembly includes a drive gear 605, a driven gear 606, and two synchronous belts 610. The drive gear 605 and the driven gear 606 are respectively fixedly sleeved on the outer walls of the two rotating shafts 602 and mesh with each other. The two synchronous belts 610 are respectively sleeved on the outer walls of one rotating shaft 602 and the other rotating shaft 607.

[0026] When motor 601 is operating, its output end drives one of the rotating shafts 602 to rotate. When rotating shaft 602 rotates, it drives the drive gear 605 to rotate. When the drive gear 605 rotates, it meshes with the driven gear 606 and drives the other rotating shaft 602 of the driven gear 606 to rotate. Under the transmission action of the two synchronous belts 610, the two rotating shafts 607 also rotate in opposite directions, which in turn causes the crushing rollers 608 and 609 to rotate in opposite directions. Through the transmission components, the linkage of the equipment is effectively improved, while saving power resources and further improving applicability.

[0027] like Figure 1 and Figure 4 As shown, in one embodiment, the spraying assembly 8 further includes a support frame 801, a protective cover 802, and a guide pipe 804. The support frame 801 is fixedly installed on the top of the two connecting plates 7. The protective cover 802 is fixedly connected to the top of the support frame 801. The liquid storage tank 803 is fixedly installed inside the protective cover 802. One end of the guide pipe 804 is connected to a water pump, and the other end is connected to an integrated spray head 805. The top of the liquid storage tank 803 is connected to a feed pipe 806.

[0028] After the water pump operates, the paint is drawn from the storage tank 803 into the guide pipe 804, and then the paint is filled into the integrated nozzle 805 through the guide pipe 804, and then sprayed out through the integrated nozzle 805. The protective cover 802 is used to protect the storage tank 803 and improve the protective effect of the storage tank 803.

[0029] like Figure 5 As shown, in one embodiment, a guide plate 101 is fixedly installed at one end of the vibrating screen 10.

[0030] The guide plate 101 can guide the sprayed material and improve the aggregate collection effect.

[0031] The working principle of this device for strengthening recycled aggregates will be explained in detail below:

[0032] The operator first starts motor 601, vibrating screen 10, and water pump. When motor 601 operates, its output drives one of the rotating shafts 602 to rotate. The rotation of shaft 602 drives drive gear 605 to rotate. Drive gear 605 meshes with driven gear 606, driving the other rotating shaft 602 of driven gear 606 to rotate. At this time, crushing roller 603 and crushing roller 604 rotate in opposite directions. Simultaneously, under the transmission action of two synchronous belts 610, two rotating shafts 607 also rotate in opposite directions, causing crushing roller 608 and crushing roller 609 to rotate in opposite directions. Then the entire... Large or chunky concrete waste is fed into the crushing box 5 from feed hopper 1 501, while smaller pieces of concrete waste are fed into the crushing box 5 from feed hopper 2 502. At this time, crushing roller 1 603 and crushing roller 2 604 crush the larger pieces of concrete waste. After the concrete waste is crushed, it is further crushed by crushing roller 3 608 and crushing roller 4 609. The material fed from feed hopper 2 502 is crushed by crushing roller 3 608 and crushing roller 4 609 first, which ensures that large pieces of material are initially crushed and that smaller pieces of material are not blocked by large pieces of material, thereby effectively improving the crushing efficiency of concrete waste.

[0033] After being crushed, the material falls onto the vibrating screen 10 and is then conveyed by the vibrating screen 10. At this time, the water pump can spray the coating inside the storage tank 803 from the integrated nozzle 805, and then spray it onto the material to increase the roughness of the aggregate surface. At the same time, the vibrating screen 10 can vibrate the material, which, together with the integrated nozzle 805, can improve the spraying effect and has strong applicability.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
