Description

A light debris separation system for construction waste recycling

technical field

The invention relates to a regeneration treatment system for construction waste, in particular to a light foreign material separation system for regeneration treatment of construction waste.

Background technique

At present, the construction waste produced in our country reaches more than one billion tons every year. A large amount of construction waste not only seriously affects people's lives, but also hinders the development of cities. An important issue faced by waste disposal units. At present, my country's construction waste treatment methods are roughly divided into two types: the first is to build a special site, and the construction waste is buried or dumped in a fixed place; Garbage is shredded and processed into reusable building materials. In the long run, the second method is undoubtedly the best way.

At present, the most common method of recycling construction waste is the production process of crushing, screening, conveying and removing impurities. After crushing and screening, the recycled aggregate of construction waste also contains a certain amount of light impurities such as wood chips and plastics. The last process of the process, the efficiency of the impurity removal process directly affects the quality of the finished product.

The light debris separation system for recycling construction waste is characterized in that: the vibrating screen is equipped with an exciter, which can carry out horizontal frequency conversion movement, and can make a single material particle form self-rotation, and the material passes through its own weight along the After a certain distance from the screen surface, a separated material layer can be formed according to the difference in specific gravity, and the light material layer floats on the material layer, which is beneficial to the discharge of light impurities.

The light debris separation system for recycling construction waste is characterized in that: there is a damping spring between the connecting part of the vibrating screen and the casing.

When in use, the material freely falls into the casing from the feed inlet, and slides down to the bulk material plate after being decelerated by the feed baffle. The belt-shaped waterfall can make the material enter the vibrating screen evenly and continuously, and the belt-shaped material layer also makes the vibrating screening efficiency of the system higher; after the material reaches the vibrating screen, driven by its horizontal frequency conversion movement, a single material particle Self-rotation can be formed. Due to the large difference in the specific gravity of the material, the material will form a separated material layer according to the difference in specific gravity after a certain distance along the screen surface by its own weight. The positive pressure wind entering the machine cavity can form an upward aerodynamic force on the materials on the screen, and the light impurities will float to the negative pressure area of the air outlet under the drive of the positive pressure wind, and the larger particles will suffer pressure loss and gravity during the movement. Working together, the light impurities that fall into the left side of the equipment are discharged from the outlet, while the tiny particles and dust in the material can be collected and discharged to the air outlet with the air pressure, so that the system has no dust pollution; the heavy material layer is much larger than that due to its gravity. Under the action of wind force, it directly falls into the lower part of the machine body through the sieve holes and grate partitions, and is discharged through the material outlet.

1. The system is composed of air outlet, casing, feed inlet, feed baffle, bulk material plate, vibrating screen, air inlet, grate partition, heavy material outlet and light material outlet. The whole machine is integrated. The structure is simple, the occupied area is small, the operation is simple, and the removal efficiency is high.

2. The air inlet and outlet of the system form a positive pressure point and a negative pressure point respectively, so that a stable wind with a uniform flow direction is formed inside the machine.

3. The feeding baffle and the bulk material plate are arranged in sequence below the feed inlet of the system, which can transform the material entering the machine cavity from a random agglomeration into a belt-shaped waterfall, so that the material enters the vibrating screen evenly and continuously. , At the same time, the belt-shaped material layer also greatly improves the vibrating screening efficiency of the system.

4. The screen inside the system is equipped with an exciter, which can carry out horizontal frequency conversion movement, which can make a single material particle form a self-rotation, and the material can form a separated material layer according to the difference in specific gravity after a certain distance along the screen surface by its own weight, and a light material layer Floating on the material layer is beneficial to the discharge of light impurities.

5. The air inlet on the lower right side of the system is located behind the screen to maximize the wind receiving area and greatly improve the winnowing efficiency. The air inlet can be equipped with an air regulating valve, and the wind force can be adjusted according to the needs.

6. In this system, the light impurities are driven by the positive pressure wind to the negative pressure area of the air outlet, and the larger particles are affected by the pressure loss and gravity during the movement, and fall into the light impurity outlet on the left side of the equipment to be discharged. The tiny particles and dust in the material can be collected and discharged to the air outlet with the air pressure, so that the system has no dust pollution.

7. The design of the system is reasonable, and the impurity removal rate is as high as 97%, far exceeding the level of existing equipment.
