Description

Clean complete sets is selected separately to building rubbish recycled aggregate accuracy

Technical Field

The utility model relates to a solid waste material resource utilization mechanical equipment field of building especially relates to a clean complete sets is selected separately to building rubbish recycled aggregate accuracy.

Background

The construction waste refers to the general name of dregs, waste concrete, waste bricks and stones and other wastes produced by people in the production activities of the construction industry such as demolition, construction, decoration and repair. With the development of the urbanization process of China, a large amount of construction waste is generated, and then the situation of 'surrounding city of waste' is developed, the recycling rate of the construction waste in foreign countries reaches 100% according to statistics, while only 5% is generated in China, and the improvement of the recycling rate of the construction waste is urgent.

The construction waste is composed of a great variety of materials, mainly red bricks and concrete, and secondarily light materials such as wood, plastics, rubber, ceramic sheets and the like. Because the physical properties of the red bricks and the concrete are different greatly, the mixed red bricks and the concrete have poor recycling effect, and if the construction waste can be accurately sorted, the respective utilization value is improved, and the method has great significance for improving the recycling rate of the construction waste.

Other enterprises and individuals have also studied the construction waste red brick and concrete sorting method and achieved corresponding results. Patent CN201510305081.0 proposes utilizing building rubbish color sorting system to select separately according to red brick and different colours of concrete, and this method has the difficult problem of controlling of sorting quality, because not only contain red brick and concrete in the building rubbish, light material such as timber, plastics, rubber, ceramic sheet mixes including can't clear away in addition, and unclean building rubbish simultaneously, debris such as earth and concrete are attached to the surface, and the color sorting system can't accurately be discriminated. The solution described in patent CN201810264249.1 also has the above drawbacks.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an improve the sorting quality, the clean complete sets is selected separately to the special design building rubbish recycled aggregate accuracy, through this equipment cleaning process after, can be accurate select separately light material, red brick and concrete etc. in the building rubbish, improve building rubbish's regeneration utilization ratio.

The technical scheme of the utility model lies in:

the utility model provides a clean complete sets is selected separately to building rubbish recycled aggregate precision, this equipment includes: the device comprises a blanking buffer bin, a winnowing machine, a light material collecting device, a water permeable barrier, a circulating water tank, a vibration table, a rotary aggregate elevator, a water filtering aggregate elevator bucket, a conveyor belt, a brick concrete sorting bin, an adjustable ironing plate, an LED light source, a CCD imaging device, an adjustable high-pressure air jet device, a red brick discharging bin and a concrete discharging bin; one side of the lower opening of the blanking buffer bin is connected with a winnowing machine, the other side of the lower opening of the blanking buffer bin is connected with a light material collecting device, a circulating water tank is arranged under the blanking buffer bin, a water-permeable barrier is arranged under the winnowing machine, a vibration table is arranged in the circulating water tank, a certain space is reserved between the inclined vibration table and the water-permeable barrier to allow construction waste recycled aggregate to enter a rotary aggregate lifting machine in the circulating water tank and be externally connected with a water-filtered aggregate lifting bucket, a conveying belt is arranged at the lower opening of the water-filtered aggregate lifting bucket and conveys the construction waste recycled aggregate into a brick concrete sorting bin, an adjustable ironing plate is arranged at the inlet of the brick concrete sorting bin, an LED light source, a CCD imaging device and an adjustable high-pressure air injection device.

The cleaning method comprises the following steps: the dust and soil on the surface of the recycled aggregate can be cleaned by passing air and water.

Gravity separation: comprises buoyancy, compressed air and high-speed airflow;

image processing: the method comprises the steps of classifying recycled aggregates according to a certain rule by using high-speed high-definition multi-head camera equipment, sorting out wood, plastic sheets, rubber and ceramic sheets according to the classification and the sequence of high-speed airflow sub-doors through adjustable program control, and accurately separating brick and concrete materials to obtain clean recycled aggregates with basic classification and clearness.

The utility model has the advantages that:

the utility model provides the high sorting quality, through selection by winnowing, water selection and based on gravity and image analysis's method, clean processing back, light material, red brick and concrete etc. in can the accurate building rubbish of selecting separately improve building rubbish regeneration utilization.

Detailed Description

Example 1

Building garbage recycled aggregate which is subjected to iron removal and crushing to meet the specification enters a blanking buffer bin (1), a valve of the blanking buffer bin (1) is opened to enable the recycled aggregate to fall uniformly, a winnowing machine (2) blows light materials such as plastics, foams and wood blocks into a light material collecting device (3), the rest recycled aggregate falls into a circulating water tank (5) filled with water, a vibration table (6) vibrates to clean the recycled aggregate and enable the light materials which are not removed and are mixed in the middle of the aggregate to float upwards, clean aggregate which is filtered to remove the light materials through a water-permeable barrier (4) enters a rotary aggregate elevator (7), the clean aggregate is conveyed to a conveyor belt (9) through a water-filtered aggregate lifting bucket (8), the conveyor belt (9) rotates the recycled aggregate to enter a brick concrete sorting bin (10), the recycled aggregate is spread and dispersed evenly through an adjustable flat plate (11), an LED light source (12) and a CCD imaging device (13) acquire image data, and forming a digital signal and transmitting the digital signal to an adjustable high-pressure air injection device (14), changing the falling track of the recycled aggregate according to different colors of the red bricks and the concrete, so that the red bricks enter a red brick discharging bin (15), and the concrete enters a concrete discharging bin (16).

After the mixed recycled aggregate enters a brick concrete sorting bin (10), under the auxiliary illumination of an LED light source (12), a CCD imaging device (13) collects imaging data and sends an instruction to an adjustable high-pressure air injection device (14), and when the instruction information is red bricks, the adjustable high-pressure air injection device (14) injects high-pressure air to blow off the falling aggregate from the original track and enter a red brick discharging bin (15); when the instruction information is concrete, the adjustable high-pressure air injection device (14) is not started, and the concrete aggregate continues to enter the concrete discharging bin (16) along the original falling track.
