[0002] Construction waste is one of the main construction wastes. Due to the characteristics of soil, sand and other substances, it can have various uses after treatment. For example, it can be used to fill depressions to make the road surface flat, build ecological landscapes to provide a growth environment for plants, and be used as a filler to prepare building materials such as cement and bricks. However, the construction waste contains steel bars, soil and other non-construction waste such as broken wood, and the screening is troublesome. For steel bars, they can be recycled but cannot be used as fillers for cement and bricks. Therefore, they need to be screened out and collected independently. For wood chips, foam, etc. that are easy to float on the water surface, water washing screening can be used, but it is relatively troublesome to drain the water of the construction waste during the water washing process and screen out the floating substances, and the operation is cumbersome.

Detailed implementation mode

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0019] Refer to Figures 1-4 , a fine treatment and recycling device for construction waste, including a crushing mechanism, a conveyor belt 2, a magnetic adsorption and removal mechanism, a sieve plate mechanism and a recycling and sorting box 8. The crushing mechanism includes three groups of crushing rollers 1 and two material collecting plates 11 arranged on each group of crushing rollers 1. The crushing rollers 1 are evenly provided with trapezoidal protrusions. Each group of the material collecting plates 11 is in a funnel shape and the bottom end is at the crushing opening above the two crushing rollers 1. The feeding end of the conveyor belt 2 is directly below the crushing mechanism. The output end of the conveyor belt 2 is above the sieve plate mechanism. Above the middle position of the conveyor belt 2, there is a magnetic adsorption and removal mechanism. The magnetic adsorption and removal mechanism includes a removal belt 3 perpendicular to the conveyor belt 2 and electromagnets 4 evenly distributed on the removal belt 3. Elastic conductive sheets 41 are connected to both sides of each electromagnet 4. Above the conveyor belt 2, there are two parallel power supply guide rods 5 and the two power supply guide rods 5 are in contact with the lower surface of the elastic conductive sheets 41. The sieve plate mechanism includes a material leakage box 6, a vibrating sieve plate 7 and a vibrating motor 71. A discharge hole 61 is provided at the lower half of one side wall of the material leakage box 6. The top end of the vibrating sieve plate 7 is rotatably installed at the top of the inner wall of one side of the material leakage box 6, and the bottom end passes through the discharge hole 61. The vibrating sieve plate 7 is provided with a vibrating motor 71 near the bottom end. A dust collection box is provided below the material leakage box 6. Inside the recycling and sorting box 8, a water draining plate 82 is provided near the bottom. A water retaining cavity 83 is left between the water draining plate 82 and the bottom of the recycling and sorting box 8. A drain pipe 84 communicating with the water retaining cavity 83 and a manual valve are provided on the side wall of the recycling and sorting box 8.

[0020] The initial muck enters the crushing mechanism (with a sleeve outside to prevent muck from splashing). The muck enters from the position of a group of crushing rollers 1 at the top and is crushed. The muck is made into smaller lumps. After being crushed by the crushing rollers 1 twice, it reaches the recycled lump size, and the wrapped steel bars are stripped and separated, then fall onto the conveyor belt 2 and are transported away. When the muck is transported under the suction and transportation mechanism, it is adsorbed by the electromagnet 4 and leaves the conveyor belt 2. The rotating transportation belt 3 transports the adsorbed steel bars and the like away. When the elastic conductive sheets 41 at both ends of the electromagnet leave the power supply guide rod 5, the power supply is immediately disconnected, the electromagnet loses magnetism, and the steel bars automatically fall and are collected.

[0021] The muck is transported into the leakage box 6 and falls onto the vibrating sieve plate 7, and the dust and fine particles are sieved out through the vibration of the vibrating motor 71.

[0022] Finally, the muck is transported into the recycling and sorting box 8 filled with water. The muck settles, and the floating substances float up until the recycling and sorting box 8 is filled with muck. The floating substances will flow away with the overflowing water, realizing the screening of floating substances. Then, the manual valve on the drain pipe 84 is opened to drain the residual water and drain the water. It is moved to one side, and another recycling and sorting box 8 is replaced to collect the next batch of muck.

[0023] The distance between the three groups of crushing rollers 1 in the crushing mechanism gradually becomes narrower from top to bottom, and the distance between the crushing rollers 1 at the bottom is between 5 - 15 cm. Since it is difficult to directly crush large lumps of muck into smaller lumps, it is extremely easy to cause jamming and immobility during rolling. Therefore, step-by-step rolling is carried out to facilitate rolling and achieve effective crushing.

[0024] The elastic conductive sheet 41 is bent downward from the connection end of the electromagnet 4 to the other end. The power supply guide rod 5 is provided with downward-bent arc-shaped rods 51 at both ends. The arc-shaped rods 51 facilitate the entry of the elastic conductive sheet 41 into the power supply guide rod 5 to achieve power supply.

[0025] The right half of the transportation belt 3 is located 15 - 25 cm above the conveyor belt 2, and a scrap iron collection box 40 is provided beside the left half of the transportation belt 3. The height of the muck piled up on the conveyor belt 2 generally does not exceed 10 cm, which is convenient for adsorbing steel bars and the steel bars to leave the muck and be transported away.

[0026] The vibrating sieve plate 7 is provided with screening holes inclined to it. When the vibrating sieve plate 7 is not vibrating, the screening holes are perpendicular to the horizontal plane. This facilitates the dust and particles in the muck on the inclined vibrating sieve plate 7 to fall from the screening holes without obstruction.

[0027] The two side walls at the top opening position of the recycling and sorting box 8 are provided with overflow ports 81. The overflow is carried out according to the overflow ports, which is convenient for managing the collection of the overflowing water.

[0028] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
