Background

With the acceleration of basic facilities such as buildings, roads, railways, bridges and the like and the urbanization construction in China, the rapid development of urban transformation and building industry, the service life of some old buildings, structures and urban basic facilities is removed due to the end, and more building solid wastes are generated. At present, most of the solid wastes of the buildings are not treated at all and are transported to the suburbs by construction units to be stacked or buried in the open air. The construction solid waste is large in quantity, multiple in component types and complex in property, the soil quality can be reduced by random discarding, the environmental pollution problem is more serious, and the influence is brought to the living environment of human beings.

The raw materials of the construction waste in China comprise: the characteristics of more bricks, large muck and complex components. The brick component proportion in the building solid waste is large, the water absorption of the brick is high, and the water absorption of the brick is about 4.5 times of that of concrete. The proportion of bricks greatly limits the utilization value of the recycled aggregate, and the practical separation technology of the bricks in the recycled aggregate is a bottleneck limiting the solid waste and resource utilization of the building. Therefore, the technology for separating the building solid waste recycled aggregate bricks from the concrete can reduce the environmental pollution and greatly improve the utilization value of the recycled aggregate.

With the intensive research on the hidden value of recycled aggregates, the inlets of the conventional separating devices are all made of rectangular steel, and the aggregates directly fall into the middle of the sieve plate to cause accumulation, so that the separation effect is reduced. Secondly, the periphery of the general separation device is not closed from the inlet to the screen plate, so that dust can fly, and secondary pollution to air is caused. The purpose of building solid waste recycling can not be achieved.

Disclosure of Invention

Aiming at the problems of nonuniform aggregate accumulation and easy secondary air pollution, the utility model provides the distributing device of the dust-falling brick and concrete specific gravity sorting device, which not only can uniformly distribute regenerated aggregate bricks and concrete on a sieve plate, but also can effectively reduce the pollution of dust.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the traditional distributing device is improved, and an arc-shaped bend with closed periphery is added at the lower part of the distributing device, so that the recycled aggregate bricks and the concrete stably fall into the middle of the sieve plate, the impact force on the sieve plate is reduced, and the purposes that the recycled aggregate bricks and the concrete are uniformly distributed on the sieve plate and the dust can be effectively suppressed are achieved.

This distributing device includes: feeder hopper 1, arc track 2, outside fixed knot construct 3.

Feeder hopper 1, characterized by: the material is 10# steel, and the shape is four sides toper funnel, and the upper portion size of feeder hopper is long 1150mm, wide 450mm, the feeder hopper lower part is connected with the arc track, and the appearance of export is rectangle, and the size is long 1150mm, wide 80 mm. The feeding hopper receives construction waste recycled aggregate from the belt conveyor, is positioned at the upper part of the whole distributing device, is connected with the arc-shaped track at the lower part and is fixed with the sorting machine through the outer side fixing device.

The arc track 2 is characterized in that: the material is 10# steel, and the feed inlet is connected on upper portion, and middle shape accords with the radius and is the fifth circular arc of 100mm, and the lower part is just to the sieve positive center, apart from the sieve positive center 200mm, and orbital design of arc is favorable to increasing the whereabouts time of brick and concrete, and the terminal slope of arc track is 0, is the horizontal export, and whole radian is comparatively mild, is difficult for causing the aggregate to pile up, has further improved the separation effect.

The outer side fixing structure 3 is characterized in that: the metal frame structure is a cuboid and is connected with an outer frame structure of the specific gravity sorting machine in a bolt mode, and the metal frame structure has the function of fixing a distributing device and keeping the stability of machinery under working vibration.

The utility model has the beneficial effects that: through the further design of arc track, realize the even feeding of construction waste recycled aggregate on the sieve, improve the homogeneity of aggregate distribution thickness on the sieve and can the dust fall.
