[0001] The invention relates to the technical field of garbage disposal, and in particular to a civil construction solid waste disposal system. Background Art

[0002] Civil construction solid waste refers to solid waste generated during the construction, maintenance and demolition of buildings. Civil construction solid waste mainly includes the following categories: Construction waste: This is the main component of civil construction solid waste, including waste concrete blocks, waste asphalt concrete blocks, broken brick slag, slag, etc. These wastes are usually generated during the construction and demolition process. Construction waste: During the civil construction process, some wastes such as packaging materials, waste metals, waste wood, etc. are also generated. These wastes may come from the packaging of building materials, damage or replacement of construction equipment, etc.

[0003] The civil engineering solid waste treatment system is a comprehensive management system that aims to efficiently and environmentally friendly treat the solid waste generated during the civil engineering process through scientific methods and advanced technical means.

[0004] The prior art, for example, invented a device and method for solid waste classification, with the authorization announcement number CN102319674B. Although it can achieve the separation of light waste from other solid waste, some light waste is still mixed with other solid waste and cannot be screened out by the wind separator, and it is not easy to separate and recycle steel bars and nails. Moreover, in the process of waste treatment, a large amount of dust is easily generated, causing environmental pollution.

[0005] Therefore, in view of the above problems, a civil engineering solid waste treatment system is proposed to solve the above problems. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention develops a civil engineering solid waste treatment system, which can conveniently screen out light waste, separate steel bars and nails, etc., and at the same time realize powdering of other wastes.

[0007] The technical solution to the technical problem of the present invention is as follows: the present invention provides a civil engineering solid waste treatment system, including: a chassis assembly and a crushing assembly; the chassis assembly includes a feed pipe, the feed pipe is fixedly connected to a cylindrical box, the cylindrical box is provided with a feeding trough, the cylindrical box is connected to a vertical box, the vertical box is fixedly connected to an oblique box, the oblique box is fixedly connected to a discharge box, the vertical box and the discharge box are respectively connected to a bracket; the crushing assembly includes a symmetrical crushing roller and a symmetrical grinding roller, the central axes of the symmetrical crushing rollers are respectively connected to the vertical box by bearings, and the central axes of the symmetrical grinding rollers are respectively connected to the discharge box by bearings; the symmetrical crushing rollers are respectively connected to a group of uniformly distributed crushing protrusions. Civil engineering solid waste is poured into the feed pipe manually or by using equipment, and the crushing protrusions are used to squeeze the solid waste, and the crushing protrusions and the crushing protrusions and the crushing rollers squeeze the solid waste to achieve the crushing of the solid waste, so that it becomes smaller blocks, which is convenient for subsequent treatment. After the blocks contact the grinding rollers, they are ground into smaller powders by the grinding rollers, so that the treatment of civil engineering solid waste is achieved, and it is convenient to use.

[0008] As an optimization, the central axes of the symmetrical crushing rollers are respectively connected to the first gears, the symmetrical first gears mesh with each other, the central axes of the symmetrical grinding rollers are respectively connected to the second gears, the symmetrical second gears mesh with each other, one first gear and one second gear are respectively connected to the synchronous wheels, and the two ends of the synchronous belt surround the corresponding synchronous wheels. By adopting gear meshing, the two crushing rollers and the two grinding rollers can rotate synchronously in opposite directions to achieve the treatment of solid waste.

[0009] As an optimization, a wind selection component is also included, the wind selection component includes a wind selection machine, the inclined box is connected to the wind selection machine, and the inclined box is provided with perforations corresponding to the wind selection machine. By using the wind selection machine, light waste can be screened out and separated from other waste.

By adopting the electromagnetic plate, it is convenient to realize the magnetic attraction of steel bars and nails, etc., and to realize the separation from other fixed wastes. The electromagnetic plate swings with the swing plate. When the electromagnetic plate is horizontal, it realizes "temporary storage" of wastes, realizes the magnetic attraction of steel bars and nails, etc., and then it swings and tilts to facilitate the falling of other solid wastes, and the motion range of the electromagnetic plate is projected in the horizontal plane within the area composed of the axes of the two grinding rollers, ensuring that the solid waste falls between the two grinding rollers for subsequent processing.

[0011] As an optimization, the inclined box is connected to the U-axis, the swing plate is connected to a symmetrical mounting seat, the U-axis is rotatably connected to the limit rod, the symmetrical mounting seats are respectively rotatably connected to the mounting shafts, the mounting shafts are connected to the U-shaped rod, the U-shaped rod is rotatably connected to the limit rod, the mounting shaft is connected to the active bevel gear, the swing plate is rotatably connected to the central axis of a group of sprockets, the chain surrounds a group of the sprockets, the active bevel gear meshes with the driven bevel gear, the driven bevel gear is connected to the corresponding sprocket, and the central axis of each sprocket is respectively connected to the diamond knife.

When the block falls, it contacts the thicker edge of the diamond knife to achieve collision and crushing of the block. The light garbage falls slowly. With the inclined box, the light waste and other fixed waste are accumulated, reducing the speed of the block waste. As the diamond knife and the electromagnetic plate move to Figure 7 In the state shown, the heavier garbage falls first, with a fast speed at the bottom close to the electromagnetic plate, while the light garbage is at a slow speed at the top, so that the light waste is at the top and moves at a low speed, which is convenient for the air separator to screen.

[0012] As an optimization, the inclined box is equipped with a box door. When the device is shut down, the box door is opened to cut off the power to the electromagnetic plate, making it convenient to remove the steel bars and nails.

[0016] As an optimization, the two groups of crushing protrusions are staggeredly distributed to facilitate crushing of solid waste.

[0017] The effects provided in the content of the invention are only the effects of the embodiments, rather than all the effects of the invention. The above technical solution has the following advantages or beneficial effects: 1. This device uses a partition with rubber at the edge to seal the cylindrical box and realize sealed feeding, so as to avoid the upward movement of dust generated during the solid waste treatment process and protect the environment of the work site. Adjacent partitions form a storage area to realize intermittent unloading of solid waste and intermittent treatment of solid waste, which is convenient for the subsequent treatment of light waste, steel bars, nails and other solid waste.

[0018] 2. This device uses electromagnetic plates and diamond-shaped knives. In the initial state, Figure 8 As shown in the figure, the thicker edge of the diamond knife faces the falling direction of the block, and the electromagnetic plate is inclined.
