Description

Technical Field

[0001] The utility model relates to a waste material processing device, in particular to a waste material processing device for construction engineering. Background Art

[0002] With the acceleration of urbanization and the vigorous development of the construction industry, the amount of waste generated in construction projects has increased year by year. These wastes not only include hard waste such as bricks, concrete, etc. generated during the construction process, but also include a large amount of decoration waste, such as plastic bags, wood fragments, old furniture parts and other lightweight materials. Effectively handling these construction wastes is of great significance to environmental protection and resource recycling.

[0003] Traditional construction waste treatment equipment mainly focuses on the crushing and classification of waste, aiming to convert large pieces of waste into small pieces of materials that can be reused or easily disposed of through physical methods; however, in actual operation, since decoration waste is mixed with masonry waste, direct crushing operations will cause increased machine wear, while reducing the quality of recycled materials and increasing the difficulty of subsequent processing. Therefore, it is particularly important to effectively separate decoration waste from the waste before crushing.

[0004] At present, the common practice for separating renovation waste is to use blowing to try to separate lighter waste (such as plastic bags) from heavy waste (such as bricks and stones). This method is based on the principle of density difference of waste materials of different materials, and uses strong airflow to blow light waste away from heavy waste. However, it is found in practice that some plastic bags are easily entangled in bricks and stones or other waste materials with complex structures, or even hooked, resulting in the airflow being unable to completely remove them, seriously affecting the separation effect, and thus affecting the efficiency and quality of the entire waste treatment process. Utility Model Content

[0005] In view of this, the utility model provides a waste treatment device for construction projects, which can solve the shortcoming of the current technology that when blowing air to separate lighter garbage (such as plastic bags) from heavy waste (such as bricks and stones), some plastic bags are easily entangled in bricks and stones or other waste materials with complex structures, or even hooked, resulting in the airflow being unable to completely remove them, seriously affecting the separation effect.

[0006] The technical solution is: a waste processing device for construction engineering, including a support frame, a first conveyor, a blanking frame, a discharging frame, a support platform, an electric gear roller, a toothed belt, a barb and a material-digging mechanism. The support frame is equipped with a first conveyor for conveying decoration waste, and the first conveyor is equipped with a blanking frame, the blanking frame is used to load decoration waste, a discharging frame is installed on the side of the support frame, the discharging frame is used to discharge decoration waste, a support platform is installed on the top of the blanking frame, an electric gear roller is rotatably installed on the support platform, a toothed belt is wound around the electric gear roller at intervals, the teeth on the toothed belt are meshed with the teeth on the electric gear roller, barbs are arranged at intervals on the surface of the toothed belt, the barbs are used to hook out plastic bags in the decoration waste, and a material-digging mechanism is also installed on the support platform, the material-digging mechanism is used to pull off the plastic bags hooked on the barbs.

[0007] As a further preferred solution, the material removal mechanism includes a second conveyor and a removal rod. The second conveyor is installed on the support platform. The transmission belt of the second conveyor is connected with removal rods at intervals. The removal rod is used to pull off the plastic bag hooked on the barb.

[0008] As a further preferred solution, a third conveyor is also included. The third conveyor is installed on the support platform. The third conveyor is used to convey the plastic bags pulled off by the lever, and the side surface of the third conveyor is in contact with the surface of the toothed belt.

[0009] As a further preferred solution, the side surface of the support platform is set as an inclined surface, and the inclined surface is used for the plastic bags detached from the third conveyor to slide down and discharge.

[0010] As a further preferred solution, a baffle is also included. The third conveyor is provided with a baffle, and the baffle is used to block the plastic bags conveyed on the third conveyor.

[0011] As a further preferred scheme, it also includes a water spray mechanism, which includes a fixed frame, a water spray pipe, a connecting pipe and an atomizing nozzle. The fixed frame is symmetrically arranged on the top of the blanking frame, and the water spray pipe is arranged in the fixed frame.
