Description

Recycled aggregate particle shaping equipment for resource utilization of construction waste

Technical Field

The invention relates to the technical field of resource utilization of construction waste, in particular to a shaping device for recycled aggregate particles of the resource utilization of the construction waste.

Background

At present, construction waste recycling enterprises basically continue to use the production process and equipment of traditional machine-made gravels to process recycled aggregates, because the acting forces required for crushing and shaping reinforcement of the recycled aggregates are greatly different in the aspects of loading mode, action size, duration and the like, the method determines that the shaping reinforcement recycled aggregates cannot achieve ideal effects by adopting the same equipment process as that of crushed natural stones, and after research, the research shows that a loose and porous mortar layer is adhered to the surface of the produced recycled aggregates, the porosity of the cement mortar is large, the water absorption rate is high, and in addition, a large amount of micro-cracks are accumulated in concrete blocks in the crushing process due to damage, so that the porosity of the recycled aggregates is large, the stacking density is small, and the crushing index is high The elastic modulus is low. In addition, the recycled aggregate concrete has lower durability such as impermeability, frost resistance, carbonization resistance, shrinkage, creep and chloride ion permeability resistance than common concrete.

The mortar coating layer of the recycled aggregate determines the strength and water absorption of the recycled aggregate, so that the fluctuation of water consumption of the premixed concrete is large, the quality of the concrete is difficult to control, and the key of producing high-performance premixed concrete is how to eliminate the influence of the mortar coating layer on the recycled aggregate.

The highway engineering construction teams all adopt stones which are not shaped, and the industry lacks of standardized management on the size and the shape of highway materials, particularly stones. Stone particles are combined together by asphalt, and if sharp points and weak strength at edge edges exist in stone, asphalt mucosa on a stone bonding surface can be damaged to form cracks. The flat stone is more easily broken in the using process. The folding and crushing process also causes gaps at the joint to form dust inclusions, so that the strength of the pavement is reduced.

For this reason, it is necessary to improve the performance of recycled aggregate and to perform a reinforcing treatment on low-quality recycled aggregate obtained by simple crushing. The currently common effective strengthening methods mainly comprise a vertical eccentric wheel high-speed grinding method, a heating grinding method, a horizontal rotary grinding method, a ball-milling grinding method, a rod-milling grinding method and a particle shaping strengthening method.

The drawbacks of these strengthening methods are as follows:

1. grinding method of vertical eccentric device

The pre-crushed recycled aggregate enters a cavity between the inner device and the outer device and is ground by the eccentric wheel rotating at high speed, so that a mortar layer adhered to the surface of the aggregate is ground. Due to the interaction between the particles, the more prominent edges and corners on the aggregate are also worn away, thereby improving the performance of the recycled aggregate. However, due to the limitation of the principle, the mortar layer on the recycled aggregate needs to be removed completely, repeated treatment is needed for many times, the equipment abrasion is large, and the service life is short.

2. Horizontal rotary grinding method

The apparatus is similar to an inclined screw conveyor except that the screw blades are modified into a spiral belt with grinding blocks to strengthen the recycled aggregate inside the apparatus. Generally, recycled aggregate after one-time treatment cannot meet the requirement of high-quality recycled aggregate, and a plurality of devices are required to perform multiple treatments in order to improve the treatment efficiency.

3. Heating and grinding method

The recycled aggregate is subjected to high temperature treatment at about 300 ℃ to dehydrate and embrittle the set cement, then is subjected to impact and grinding treatment in a grinder, and can be recycled after being ground twice (all the recycled aggregates comprise recycled coarse aggregate, recycled fine aggregate and micro aggregate)

4. Method of particle reshaping

The mortar and the cement stones attached to the surface of the aggregate are removed through high-speed self-impact and friction of the recycled aggregate, and the more prominent edges and corners on the aggregate particles are removed, so that the particles tend to be spherical, the recycled aggregate is reinforced, a part of the recycled aggregate enters the inner cavity of the middle impeller, is accelerated under the action of centrifugal force and is thrown out at high speed, the other part of the recycled aggregate falls along the periphery of the impeller, collides with the material thrown out by the impeller when falling, and is crushed and shaped through multiple times of collision and friction, and the high-speed material rarely contacts with a machine body, so that the service life of the equipment is long.

4. Ball milling method

Similar to the principle of a ball mill, a plurality of partition plates are arranged in the equipment, steel balls are placed in the partition plates, and the steel balls in the partition plates interact with materials through the rotation of the partition plates, so that cement paste in the recycled aggregate is removed, and the performance of the recycled aggregate is improved.

5. Rod milling method

The method is a wet processing method, water is required to be introduced into equipment, cement paste on the surface of aggregate is removed under the impact force of the special-shaped steel bars, and the recycled aggregate with different properties can be obtained by adjusting the number and the size of the special-shaped steel bars.

The recycled aggregate with the size of 5-40mm is treated by the processing methods through primary crushing and screening, and the methods have the defects of complex process, huge equipment, high power consumption and high equipment abrasion, so that the popularization and the use of the method are limited.
