Problems solved by technology

First of all, after a large amount of land is piled with construction waste, it will not only occupy a large amount of land, reduce the land utilization rate, but also reduce the quality of the soil and reduce the production capacity of the soil; the construction waste is piled in the open field, and some dust particles will be suspended in the air. Affect air quality and damage human health; long-term accumulation of construction waste will cause the toxic and harmful substances in the construction waste to seep into the groundwater and pollute the water environment; if the construction waste is piled up in the city, it will be beautiful to the urban environment There may be some safety hazards in the piling of construction waste, which may lead to safety accidents
[0003]The existing technology does not have a perfect device for processing construction waste. Some devices can process construction waste on a small scale, but cannot handle large-scale and batch processing construction waste

Embodiment 1

[0033] Such as figure 1 As shown, this embodiment proposes a treatment device for civil engineering construction waste, including a universal pulverizer 10, a magnetic separation conveyor 20, a crushing filter device and a conveying device, wherein the output end of the universal pulverizer 10 is used to put construction waste, The output end of the universal pulverizer 10 is docked with the input end of the magnetic separation conveyor 20. The magnetic separation conveyor 20 is used to remove metal impurities in the primary crushed building materials. The output end of the magnetic separation conveyor 20 is arranged to crush and filter At the input end of the device, the crushing and filtering device is used to filter the primary crushed building materials and re-shred the bulky building materials.

[0034]The device has a two-stage crushing structure, and the unbroken part of the first-stage universal pulverizer 10 is first filtered and then crushed by the second-stage crush...

Embodiment 2

[0052] A method for processing civil engineering construction waste proposed in this embodiment uses the processing device for civil engineering construction waste as in Embodiment 1, specifically, putting construction waste into a universal pulverizer 10, and crushing the construction waste through the universal pulverizer 10 Finally, the metal impurities are filtered by the magnetic separation conveyor 20, and then the construction waste after the filtered metal impurities is put into the crushing and filtering device. The construction waste enters the particle concentration bucket 328 from the filter extension 325, and the large construction waste falls into the top surface of the crushing backing plate 322, drives the breaking hammer 31 to fall, passes through the first crushing tooth 312 and the second crushing tooth, and the crushing hammer 31 and The cooperation of the crushing backing plate 322 breaks the large particles of construction waste into small particles and fa...

Abstract

The invention belongs to the field of environment-friendly machinery, and relates to a civil engineering construction waste treatment device which is characterized in that the output end of a universal pulverizer is used for putting construction waste, the output end of the universal pulverizer is in butt joint with the input end of a magnetic separation conveyor, and the magnetic separation conveyor is used for removing metal impurities in construction materials subjected to primary crushing; and the output end of the magnetic separation conveyor is arranged to the input end of the crushing and filtering device, and the crushing and filtering device is used for filtering the building materials subjected to primary crushing and re-crushing the large building materials. The device can be used for treating the building waste on a large scale, and is particularly suitable for factory use. The invention further provides a civil engineering construction waste treatment method.

Description

technical field [0001] The invention belongs to the field of environmental protection machinery, in particular to a treatment device and a treatment method for civil engineering construction waste. Background technique [0002] Construction waste has a wide range of erosive effects on our living environment. If the attitude of long-term disposal of construction waste is adopted, it will have a bad impact on urban environmental sanitation, living conditions, and land quality assessment. First of all, after a large amount of land is piled with construction waste, it will not only occupy a large amount of land, reduce the land utilization rate, but also reduce the quality of the soil and reduce the production capacity of the soil; the construction waste is piled in the open field, and some dust particles will be suspended in the air. Affect air quality and damage human health; long-term accumulation of construction waste will cause the toxic and harmful substances in the constr...
