Mixing device for preparing pavement brick from building wastes

Abstract

The invention discloses a mixing device for preparing a pavement brick from building wastes. The mixing device mainly comprises an outer frame, a water pump, a top shell, a mixing shell, a motor, a mixing plate, a transmission member and a rotating shaft, wherein the inner wall of the top end of the outer frame is fixedly provided with an anti-impact ring through a bolt; the upper part of the outer side of the anti-impact ring is assembled with the top shell by a bolt; the left side of the top shell is provided with a feeding inlet; and the central part of the right side of the top shell is fixedly provided with the water pump. The mixing device provided by the invention has reasonable design in structure; waste materials like pavement bricks are crushed and recovered by the mixing devicewithout the need of burying, so land resources and material resources are saved; old bricks are completely crushed and ground to prepare powder by the mixing device, and obtained old brick powder is mixed with a new material in a certain proportion to prepare a raw material for reutilization; through cooperation of staged crushing and flexible load-transferring construction, the mixing device is protected and is insusceptible to being damaged; meanwhile, through staged crushing, the mixing device has good powder preparation effect; and mixing of obtained powder with the new material can be completed in the mixing device, and purchasing of a single mixing device is not needed, so the cost of recovery is low.

Description

Technical field [0001] The invention relates to a construction waste recycling equipment, in particular to a mixing device for making road bricks from construction waste. Background technique [0002] Construction waste refers to the muck, waste concrete, waste masonry and other wastes produced by people in the production activities of the construction industry such as demolition, construction, decoration and repair. According to the source of generation, construction waste can be divided into engineering waste, decoration waste, demolition waste, engineering mud, etc.; according to the composition of the classification, construction waste can be divided into muck, concrete blocks, crushed stones, brick and tile fragments, Waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc. [0003] Existing construction waste, such as pavement bricks, etc., are often buried in landfills after being demolished, causing material waste; if recycling is required,...

AI Technical Summary

Problems solved by technology

[0003] Among the existing construction wastes, such as pavement bricks, etc., after dismantling, they are mostly disposed of by landfill, resulting in waste of materials; if recycling is required, the old bricks need to be completely crushed to make powder, and a certain proportion of new materials must be mixed. The raw materials are reused, and the existing equipment directly has a large volume of waste, which is easy to cause material jams and equipment damage; and the effect of crushing and milling is poor, and it is necessary to purchase a single mixing equipment for mixing with new materials, and the equipment cost is high.
