technical field

The utility model relates to a distributor of a specific gravity separation device for bricks and concrete, in particular to a distributor capable of reducing dust.

Background technique

With the acceleration of infrastructure and urbanization construction such as buildings, highways, railways, bridges, etc. in my country, and the rapid development of urban renovation and construction industry, some old buildings, structures, and urban infrastructure will be demolished after their service life expires. More and more construction solid waste. At present, the vast majority of construction solid waste is transported to the suburbs by the construction unit without any treatment, and piled up in the open air or landfilled. Construction solid waste has a large quantity, many types of components, and complex properties. Random disposal will reduce soil quality, lead to more serious environmental pollution problems, and have an impact on the living environment of human beings.

The source components of construction waste in my country have the characteristics of "many bricks, large slag, and complex components". The proportion of bricks in solid construction waste is large and the water absorption rate of bricks is high. The water absorption rate of bricks is about 4.5 times that of concrete. The proportion of bricks greatly limits the utilization value of recycled aggregates, and the practical separation technology of bricks in recycled aggregates is the bottleneck restricting the recycling of construction solid waste. For this reason, the separation technology of recycled aggregate brick and concrete around construction solid waste will not only reduce environmental pollution, but also greatly improve the utilization value of recycled aggregate.

With the gradual in-depth study of the hidden value of recycled aggregate, the entrance of the separation device is generally composed of rectangular steel, and the aggregate directly falls into the middle of the sieve plate to cause accumulation, resulting in a decrease in the separation effect. Secondly, the general separation device is not closed from the entrance to the process of falling into the sieve plate, and the phenomenon of dust flying will occur, causing secondary pollution to the air. The purpose of recycling construction solid waste cannot be achieved.

SUMMARY OF THE INVENTION

Aiming at the above-mentioned problems of uneven accumulation of aggregates and easy secondary air pollution, the utility model provides a distributor of a brick and concrete specific gravity separation device that can reduce dust. The distributor can not only make recycled aggregate bricks It is evenly distributed with the concrete on the sieve plate, and can effectively reduce the pollution of dust.

The technical scheme adopted by the utility model to solve the technical problem is as follows: the traditional distributor is improved, and an arc-shaped curve closed around is added to the lower part of the distributor, so that the recycled aggregate bricks and concrete can smoothly fall into the middle of the sieve plate, The impulse to the sieve plate is slowed down, and the recycled aggregate bricks and concrete are evenly distributed on the sieve plate and can effectively suppress dust.

The distributing device includes: a feeding hopper 1 , an arc track 2 , and an outer fixing structure 3 .

The said feeding hopper 1 is characterized in that: the material is 10# steel, the shape is a four-sided conical funnel, the upper dimension of the feeding hopper is 1150mm long and 450mm wide, the lower part of the feeding hopper is connected with the arc track, and the outlet is The shape is rectangular, the size is 1150mm long and 80mm wide. The feeding hopper receives the recycled aggregate of construction waste from the belt conveyor, and is located at the upper part of the whole distributing device, and the lower part is connected with the arc track, which is fixed with the sorting machine by the outer fixing device.

The arc-shaped track 2 is characterized in that: the material is 10# steel, the upper part is connected to the feeding port, the shape of the middle conforms to a one-fifth arc with a radius of 100mm, and the lower part is facing the center of the sieve plate and is directly away from the sieve plate. The center is 200mm, and the design of the arc track is beneficial to increase the falling time of bricks and concrete, and the slope of the end of the arc track is 0, which is a horizontal exit. The entire arc is relatively gentle, which is not easy to cause aggregate accumulation, which further improves the separation effect.

The outer fixing structure 3 is characterized in that it is a cuboid metal frame structure, which is connected with the outer frame structure of the specific gravity separator by means of bolts, and its function is to fix the distribution device and maintain the stability of the machine under working vibration. .

The beneficial effects of the utility model are as follows: through the further design of the arc track, the uniform feeding of the recycled aggregate of construction waste on the sieve plate is realized, the uniformity of the distribution thickness of the aggregate on the sieve plate is improved, and the dust can be reduced.
