Description

Construction waste crushing device

Technical Field

The utility model relates to the field of construction waste treatment, in particular to a construction waste crushing device.

Background technique

Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other wastes generated during the construction, laying, demolition and repair of various buildings, structures, pipe networks, etc. by construction units or individuals. Construction waste needs to be crushed using a crushing device to facilitate the treatment and reuse of construction waste.

When using a crushing device, the dust generated by the crushing of construction waste will splash out, which can easily affect the physical and mental health of the workers. In order to remove the dust, it is necessary to use negative pressure equipment to suck out the dust and pass the sucked dust into a water tank for adsorption. Although this method can deal with the dust generated by the crushing of construction waste, it directly passes the dust into the water. Due to the metal debris in the construction waste, some of the debris is adsorbed into the water, turning the water in the water tank into wastewater. Direct discharge can easily affect the surrounding environment.

After searching, the application number is "202222379476.3", which provides a construction waste crushing device. The worm is fixedly connected to the motor output shaft. When the motor is started, a negative pressure will be generated inside the dust guide pipe through the fan that rotates with the motor output shaft. When negative pressure is generated in the dust guide pipe, a large amount of dust generated by the two crushing rollers in the process of crushing construction waste can be discharged and enter the water tank through the dust guide pipe. Clean water is provided inside the water tank, so that the dust is dissolved in the water to reduce dust splashing.

The above-mentioned fan is used to suck out the dust generated during the crushing, and the dust is passed into the water tank. The water in the water tank is mixed with the dust and some metal debris, so that the water in the water tank becomes wastewater. Direct discharge is likely to affect the surrounding environment, and wastewater treatment equipment is required, which increases the workload of the staff.
