Technical Field

The utility model relates to the technical field of civil engineering, in particular to a device for treating construction waste in civil engineering.

Background Art

With the rapid development of social economy, the process of urbanization has also accelerated. The rapid development of urban transformation and construction industry, coupled with the aging and expiration of service life of some old buildings and urban infrastructure, has led to the scrapping and demolition of more and more civil engineering construction projects, resulting in a large amount of construction demolition waste and garbage. If it is not handled and utilized in a timely manner, it will inevitably have an adverse impact on society, the environment and resources. The construction waste can be crushed, recycled and reused, which can not only protect natural resources, but also reduce the impact of construction waste on the environment.

Construction waste generally contains a large amount of concrete and metal components. At present, when processing construction waste, it is impossible to effectively separate the metal components from the concrete. Moreover, metal and concrete are important building materials that can be effectively recycled and reused. If they cannot be effectively separated, a large amount of reusable resources will be wasted, wasting limited natural resources.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to FIG. 1 , which shows a civil engineering construction waste treatment device in this embodiment, which is used to separate metal components from concrete inside construction waste.

Specifically, it includes a box body 1, a lower hopper 2, a crushing mechanism 3, a support frame 4 and a separation mechanism 5; the lower hopper 2 is installed inside the box body 1, the crushing mechanism 3 is installed inside the box body 1, the support frame 4 is installed inside the box body 1, and the separation mechanism 5 is installed on the support frame 4.

In actual setting, construction waste is put into the lower hopper 2, and the construction waste is crushed by the crushing mechanism 3. The crushed construction waste falls on the separation mechanism 5, and the separation mechanism 5 separates the metal components and concrete debris in the construction waste.

Please refer to Figure 2. In order to separate the metal components from the concrete in the construction waste, the separation mechanism 5 in this embodiment includes at least two horizontal plates 501, and the at least two horizontal plates 501 are installed in parallel on the support frame 4. At least two transmission rollers 502 are rotatably connected between the at least two horizontal plates 501. A rotating motor 503 is installed on the horizontal plate 501, and the output end is transmission-connected to one of the transmission rollers 502. The outer sides of the at least two transmission rollers 502 are transmission-connected to the same transmission belt 504, and a magnetic plate 505 is installed on the outer side of the transmission belt 504.

During actual use, the construction waste crushed by the crushing mechanism 3 falls onto the magnetic plate 505 on the conveyor belt 504, so that the metal components in the debris are attracted to the magnetic plate 505, and the rotation of the conveyor belt 504 causes the waste to fall from the right end of the conveyor belt 504, while the metal components are still adsorbed on the magnetic plate 505.

It should be noted that the magnetic force in the magnetic plate 505 in this example is preferably controlled by electricity, that is, when power is turned on, the magnetic plate 505 generates magnetic force to adsorb metal components, and when power is lost, the magnetic force is also lost, which facilitates the falling of metal components adhered to the magnetic plate 505.

In addition, the box body 1 is shaped like a cuboid with a hollow interior and a convex lower end surface. The bottom of the box body 1 is connected to a discharge pipe, and the conveyor belt 504 is located below the discharge pipe so that the crushed construction waste falls onto the conveyor belt 504.

Please refer to Figures 3-4. In order to crush the construction waste, the crushing mechanism 3 in this embodiment includes at least two rotating shafts 301, at least two crushing rollers 302, at least two gears 303 and a driving motor 304; at least two rotating shafts 301 are rotatably connected to the right side of the inner wall of the box body 1, and the left ends of at least two rotating shafts 301 penetrate and extend to the left side of the box body 1, at least two crushing rollers 302 are respectively sleeved on the outside of the at least two rotating shafts 301, at least two gears 303 are respectively sleeved on the outside of the at least two rotating shafts 301, and at least two gears 303 are meshed with each other, and the driving motor 304 is assembled on the right side of the box body 1, and the output end of the driving motor 304 is transmission-connected to one of the rotating shafts 301.

In actual configuration, in order to ensure that the rotation speeds of the two crushing rollers 302 are consistent, in this embodiment, at least two rotating shafts 301 are arranged in parallel, and at least two gears 303 have the same outer diameter.

In actual use, the output end of the driving motor 304 is rotated to drive the rotating shaft 301 connected thereto to rotate, and the rotation of the rotating shaft 301 drives the crushing roller 302 and the gear 303 on its outer side to rotate, so that the two crushing rollers 302 are in a state of counter-rotation, and the construction waste between the two crushing rollers 302 can be crushed.

Furthermore, in order to achieve a better crushing effect on construction waste and increase the crushing efficiency of construction waste, at least two protrusions are provided on the crushing roller 302 in this embodiment, and the front and rear crushing rollers 302 are arranged in a front-to-back cross distribution.

In summary, the civil engineering construction waste processing device crushes the construction waste through the cooperation between the internal components of the crushing mechanism 3, so that the crushed construction waste falls on the magnetic plate 505 on the conveyor belt 504, and the metal components in the debris are attracted to the magnetic plate 505. The rotation of the conveyor belt 504 causes the waste to fall from the right end of the conveyor belt 504. At this time, the metal components are still adsorbed on the magnetic plate 505, so that the metal components in the construction waste can be effectively separated from the concrete.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
