Description

Technical Field

[0001] This utility model relates to the field of construction waste recycling technology, specifically a waste recycling device based on construction economics. Background Technology

[0002] Currently, the selection of construction waste dumping sites in most cities is largely arbitrary, leaving numerous safety hazards. Construction sites and their vicinity often become temporary dumping grounds for construction waste. Due to the focus on convenience during construction and the lack of adequate protective measures, these dumps frequently collapse under the influence of external factors, obstructing roads and even impacting other buildings. In suburban areas, pits and ditches are often the preferred dumping grounds for construction waste, which not only reduces the water body's water storage capacity but also diminishes surface drainage and flood control capabilities. Therefore, the indiscriminate dumping of construction waste not only directly pollutes soil, water, and air but also poses hidden safety hazards. Thus, waste recycling facilities are needed to recycle and reuse construction waste.

[0003] Existing waste recycling equipment cannot control the diameter of the crushed material when it cannot crush and recycle it. When small-diameter crushed material is required, it needs to be repeatedly recycled into the recycling equipment for crushing and processing, which affects the recycling efficiency of waste.

[0031] Example 2:

[0032] Please see Figure 1-5A waste recycling device based on construction economics includes a recycling box 1. A slide rail 6 is fixedly connected to the back of the inner cavity of the casing 406. Slider 7s are slidably connected to both sides of the surface of the slide rail 6. The end of the slider 7 away from the slide rail 6 is fixedly connected to a threaded sleeve 403, which can limit and guide the movement of the threaded sleeve 403, increasing the stability when the positive and negative threaded rods 402 drive the threaded sleeve 403 to move. The upper crushing component 2 includes two upper crushing motors 201. The output shaft of the upper crushing motors 201 is fixedly connected to an upper crushing roller 202, which can perform primary crushing of construction waste. The lower crushing component 3 includes two lower crushing motors 301, which lower the crushing rollers 301. The output shaft of the crushing motor 301 is fixedly connected to the lower crushing roller 302, which can perform secondary crushing processing on the construction waste after primary crushing. A conveyor belt 8 is provided at the bottom of the inner cavity of the recycling box 1. A discharge port 9 is opened at the bottom right side of the inner cavity of the recycling box 1. The conveyor belt 8 is located in the inner cavity of the discharge port 9, which can facilitate the conveying of the crushed waste to the outside of the recycling box 1. Limiting blocks 10 are fixedly connected around the inner cavity of the dust collection box 502. The filter screen 504 is located between the four limiting blocks 10, which can limit the filter screen 504. An inspection door 11 is provided on the surface of the dust collection box 502, which can facilitate the cleaning and maintenance of the filter screen 504.

[0033] The working principle is as follows:

[0034] When in use, when the material to be crushed is large, the servo motor 401 is started first to drive the positive and negative threaded rods 402 to rotate. The positive and negative threaded rods 402 drive the two threaded sleeves 403 to move relative to each other, which in turn drives the two discharge plates 405 to move and merge. At this time, the construction waste is added into the recycling box 1 through the feed port 12, and the two upper crushing motors 201 drive the two upper crushing rollers 202 to crush the construction waste. The crushed material will then slide into the recycling box 1 through the merged discharge plates 405.

[0035] When the material to be crushed is small, the servo motor 401 is started to drive the positive and negative threaded rods 402 to rotate in opposite directions. The positive and negative threaded rods 402 drive the two threaded sleeves 403 to move in opposite directions, which in turn drives the two discharge plates 405 to move and unfold. At this time, the construction waste that has been processed by the upper crushing component 2 will fall directly to the lower crushing component 3. Then, the two lower crushing motors 301 drive the two lower crushing rollers 302 to perform secondary crushing on the material after primary crushing, which can improve the crushing effect. Finally, it is discharged out of the recycling box 1 through the conveyor belt 8. At the same time, the exhaust fan 503 is started to generate suction. The dust generated during the crushing process is absorbed and treated through the three-way pipe 505 using the two dust extraction heads 501 to prevent dust from spreading and affecting the surrounding environment.

[0036] In summary, this construction waste recycling device, through the upper crushing component 2, enables primary crushing of construction waste. The lower crushing component 3 further enhances the crushing effect by performing secondary crushing on the primary crushed waste. The movable discharge component 4 allows for rapid discharge of materials requiring crushing, improving recycling efficiency. Finally, the dust removal component 5 absorbs and treats the dust generated during the crushing process, preventing dust from spreading and impacting the surrounding environment.
