Problems solved by technology

This separate treatment process not only has multiple losses of equipment energy, but the quality of the coarse and fine recycled aggregates and recycled micropowder produced is not high enough, and the gradation is not reasonable enough. In addition, dust is often generated during the production process, which pollutes the urban environment again (even if Some grinding equipment comes with corresponding dust collection equipment)

Embodiment 1

[0024] Such as figure 1 As shown, the environment-friendly recycled aggregate strengthening and pulverizing system of the present invention includes a fan 1, a motor 2, a refitted particle shaping and strengthening equipment 3, a belt conveyor 4, an air lock bag 5, an air lock counterweight valve and a blower Plate conveyor 6, filter bag dust collector 7, pressure divider valve 8, modified Raymond mill 9, supporting air duct 10, cyclone cylinder 11, air lock counterweight valve and screw conveyor 12. After integration, a complete set of process steps covering waste concrete crushing, screening, pulverizing and dust collection is obtained, as follows:

[0025] 1) Under the condition that the motor 2 drives the spreader and the fan 1 blows air, the waste concrete blocks enter the particle shaping and strengthening equipment 3 with the feeding port of the air lock bag 5 through the belt conveyor 4, and the blocks are centrifuged By controlling the air volume and wind speed per u...

Embodiment 2

[0029] The difference from Example 1 is that the cyclone 11 is two cyclones 11 of the same specification connected in parallel, and the supporting air ducts 10 of the two cyclones 11 are respectively connected to the modified particle shaping and strengthening equipment 3 and the filter bag dust collector 7 . All the other are the same as in Example 1.

Embodiment 3

[0031] The difference from Example 1 is that the feed inlet of the refitted Raymond mill 9 is completely sealed, and the air inlet of the bag filter 7 is only connected to the air outlet of the fan 1 and the cyclone 11 by the supporting air duct 10, forming a whole series series system. Specific as attached figure 2 . All the other are the same as in Example 1.

Abstract

The invention discloses an environment-friendly recycled aggregate reinforcement and powder production integrated system. The system comprises a particular shaping reinforcement equipment system, a powder production system and an adjusting system; the particle shaping reinforcement equipment system includes particle shaping reinforcement equipment, a motor, a fan, a belt conveyor, a lock wind buckle bag, a lock wind counterweight valve, a matched wind pipe and a matched bracket; the powder production system includes a refitted Raymond mill, a cyclone cylinder, a matched wind pipe, a matched bracket and a dust collecting and wind pressure adjusting system; and the adjusting system includes a pressure filter bag dust collector, a pressure division valve and a matched bracket. The system effectively integrates waste concrete recycled aggregate crushing, shaping reinforcement, powder production and dust collecting processes as a whole to prepare recycled aggregates and recycled micro powder for recycled concrete, and effectively reduces the dust emission.

Description

technical field [0001] The invention belongs to the technical field of green building materials and its production and application, and specifically relates to the resource utilization of construction waste, the preparation of recycled aggregate and recycled micropowder for recycled concrete, and an environmentally friendly recycled aggregate reinforcement and pulverization that can effectively reduce dust emissions. integrated system. Background technique [0002] Although concrete materials have a long service life, concrete structures and buildings will eventually have to be demolished due to various factors after a period of use, resulting in a large amount of waste concrete. On the other hand, with the development of social economy and the increase of the amount of concrete, the resource depletion and environmental damage caused by the mining of sand and gravel aggregates have become the focus of engineering and technical personnel. The sustainable development of concre...
