Description

Technical Field

[0001] The invention relates to the technical field of light and heavy object separation of construction waste, and in particular to an air separator used for light and heavy object separation of construction waste. Background Art

[0002] The recycling of construction waste requires sorting and crushing of construction waste, and finally sorting out the usable materials and preparing recycled aggregates. Since the composition of construction waste itself is very complex, it contains metal objects, concrete blocks, and lightweight objects such as foam boards and plastic films. Therefore, among the many sorting processes, there is a process that requires sorting light and heavy materials.

[0003] Traditionally, the sorting of light and heavy materials relies on air separators, but the sorting method is: the construction waste is naturally dropped by unloading equipment, and then the naturally dropped construction waste is blown by air blowing equipment. Under the action of wind, the falling trajectories of light and heavy materials change, thereby achieving the separation of light and heavy materials. However, the above sorting method can only sort the construction waste once, and it is inevitable that the light and heavy materials of the construction waste will not be completely separated during the sorting. This requires the staff to collect and sort the light and heavy materials of the construction waste again after the sorting, thereby reducing the sorting quality and efficiency. Summary of the invention

During the sorting, it is inevitable that the light and heavy objects in the construction waste will not be completely separated.

[0034] The air separation box 14 is connected to the interior of the protection box 1, and the rear surface of the air separation box 14 is fixedly connected to the first discharge box 12 connected thereto, and the interior of the first discharge box 12 is fixedly connected to a triangular baffle 21;

[0035] Among them, the lower surface of the first discharge box 12 is fixedly connected to the second discharge box 13 communicated with it, the rear inner wall of the air separation box 14 is fixedly connected to the first inclined plate 19, and the rear inner wall of the air separation box 14 is fixedly connected to the second inclined plate 22, and the second inclined plate 22 is located below the first inclined plate 19.

[0036] Furthermore, a second centrifugal fan 18 is fixedly installed on the upper surface of the protection box 1, and a rectangular connecting pipe 7 is fixedly installed at the air outlet of the second centrifugal fan 18 through a connecting piece;

[0037] The rectangular connecting pipe 7 is connected to the air outlet of the second centrifugal fan 18 , and the rear surface of the rectangular connecting pipe 7 is fixedly connected to an air outlet box 8 connected thereto, and the rear end of the air outlet box 8 passes through the interior of the air inlet selection box 14 .

[0038] Furthermore, two fixing plates 17 are fixedly connected to the right side of the protective box 1, and connecting pipes 16 are fixedly connected to the opposite surfaces of the two fixing plates 17. The left side of the connecting pipe 16 is fixedly connected to a rectangular air outlet box 25 that is communicated with the connecting pipe, and the left side of the rectangular air outlet box 25 passes through the interior of the protective box 1.

[0039] Furthermore, the left side of the rectangular air outlet box 25 is fixedly connected to an arc-shaped material outlet box 15 communicating therewith, and the inner wall of the protection box 1 is fixedly connected to a third inclined plate 23 .

[0040] Furthermore, a first centrifugal fan 11 is fixedly installed on the upper surface of the first discharge box 12, and an air outlet of the first centrifugal fan 11 is fixedly connected to an air pipe 10, and one end of the air pipe 10 away from the first centrifugal fan 11 is fixedly connected to a connecting pipe 16, and the air pipe 10 and the connecting pipe 16 are in communication.

[0041] Furthermore, the upper surfaces of the protection box 1 and the rectangular plate 3 are fixedly connected to the support frame 2, the upper surfaces of the two support frames 2 are fixedly installed with a first conveying mechanism 5, and the conveyor belt on the first conveying mechanism 5 is fixedly connected to a plurality of rectangular baffles 6.

[0042] Furthermore, the upper surface of the air separation box 14 is fixedly connected to an arc-shaped feed box 9 which is in communication therewith, and the rear end of the first conveying mechanism 5 extends into the interior of the arc-shaped feed box 9;

[0043] A second conveying mechanism 24 is fixedly installed inside the support frame 2 , a rectangular groove 20 communicating with the protective box 1 is formed on the front surface thereof, and a front end of the second conveying mechanism 24 extends out of the inner wall of the rectangular groove 20 .

[0044] Furthermore, when using the air separator for separating light and heavy objects of construction waste, the first conveying mechanism 5 is first started, and the operation direction of the first conveying mechanism 5 is moved from front to back, and the first centrifugal fan 11 and the second centrifugal fan 18 are started at the same time, and the second conveying mechanism 24 is started at the same time, and the operation direction of the second conveying mechanism 24 is moved from back to front;

[0045] Then, the staff puts the construction waste into the first conveying mechanism 5 through an external tool. The rectangular baffle 6 on the first conveying mechanism 5 will group the multiple construction wastes to prevent too much construction waste from entering the dynamic air separation box 14 at one time, which will affect the sorting quality, thereby improving the sorting quality.

[0046] Among them, the construction waste enters the interior of the air separation box 14 through the arc-shaped feed box 9, and the construction waste will fall on the first inclined plate 19, and fall toward the air outlet box 8 along the inclined surface of the first inclined plate 19, so that the construction waste falls in an inclined shape, thereby making the construction waste fall more dispersed, so that the airflow can completely pass through multiple construction wastes, thereby further improving the sorting quality;

[0047] Among them, a plurality of construction wastes fall down, and the airflow generated by the second centrifugal fan 18 is blown into the interior of the air separation box 14 through the rectangular connecting pipe 7 and the air outlet box 8. The airflow passes through the plurality of construction wastes that are falling, and the lighter construction wastes (plastic bags, plastic boards, foam boxes, lighter plastics, etc.) are blown into the interior of the first discharge box 12, and the heavier construction wastes will fall onto the second inclined plate 22, and then fall onto the first conveying mechanism 5 along the second inclined plate 22;

[0048] The lighter construction waste will follow the inclined surface of the triangular baffle 21 or directly enter the first discharge box 12, and follow the airflow direction to enter the second discharge box 13 for discharge. The triangular baffle 21 can block the lighter construction waste and the airflow, preventing the airflow from flowing back and causing the lighter construction waste to be unable to be discharged normally, thereby improving the discharge stability of the air separator used for separating light and heavy construction waste.

[0049] The construction waste that has been sorted for the first time falls onto the first conveying mechanism 5, and the first conveying mechanism 5 drives the construction waste that has been sorted for the first time to move forward. The first centrifugal fan 11 inputs the generated airflow into the interior of the connecting pipe 16 through the air delivery pipe 10, and finally discharges it through the rectangular air outlet box 25. The airflow blows the construction waste that has been sorted for the first time again, and sorts the lighter construction waste that has not been sorted for the first time again, and blows the lighter construction waste into the interior of the arc-shaped discharge box 15.

[0050] Among them, by setting up the air separation component, a batch of construction waste can be sorted twice, thereby improving the quality of separation of light and heavy objects in construction waste, and then improving the practicality of the air separator used for separation of light and heavy objects in construction waste.

[0055] Second conveying mechanism 24: The second conveying mechanism 24 is an existing structure, which has a driving device, a supporting device and a conveying belt.

[0056] Support frame 2: The support frame 2 is arranged on the protection box 1 , and the support frame 2 supports the first conveying mechanism 5 .

[0057] Rectangular baffle 6: The rectangular baffle 6 is arranged on the conveying belt of the first conveying mechanism 5, and the rectangular baffle 6 is used to group the construction waste.

[0058] The third inclined plate 23 : The third inclined plate 23 is arranged on the protection box 1 , and the third inclined plate 23 has a blocking effect on the construction waste on the second conveying mechanism 23 .

[0059] Second inclined plate 22 : The second inclined plate 22 is disposed on the air separation box 14 to block the falling construction waste and prevent the construction waste from falling directly onto the second conveying mechanism 24 .

[0060] Second conveying mechanism 24: The second conveying mechanism 24 is used to convey the heavier construction waste after the reverse selection is completed.
