Description

Technical Field

[0001] This utility model relates to equipment for recycling and processing construction waste, and more particularly to a novel air separator for construction waste. Background Technology

[0002] Construction waste refers to solid waste generated during the construction, renovation, expansion, or demolition of buildings. Disposing of construction waste through open-air dumping or landfilling occupies a large amount of land and causes numerous problems such as environmental pollution, soil structure damage, and land subsidence. Therefore, the current common practice is to crush construction waste, sort out materials such as metal, plastic, wood, or glass, and use the aggregate obtained from the crushed construction waste to prepare recycled bricks and recycled concrete, thus recycling and reusing the construction waste.

[0003] However, since construction waste contains a large amount of lightweight materials such as wood, cloth, plastic, and aerated concrete blocks, it is usually screened using equipment such as air separators. The principle of air separators is to use wind power to separate the lighter materials with lower density and separate the heavier materials containing aggregates for the next stage. However, existing air separators usually only have a single fan, which makes it difficult to screen materials with a high content of lightweight materials in one go. This makes it difficult to meet the on-site processing needs, resulting in an excessive content of lightweight materials in the crushed material, which causes inconvenience to the subsequent processing and reduces the processing efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings of current construction waste air separation devices, this utility model provides a new type of construction waste air separation machine, which can achieve the effect of optimizing the screening rate of light materials in construction waste.

[0005] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0006] A novel air separator for construction waste includes a cylinder, a main air duct, and a main air separator device. The main air separator device is connected to the cylinder via the main air duct. A material inlet communicating with the inner cavity of the cylinder is located at the top of the cylinder, and a heavy material outlet and a light material outlet communicating with the inner cavity of the cylinder are located below the material inlet. The separator also includes a suction-type air separator device and a secondary air duct. The suction-type air separator device is located at the top of the cylinder and connected to the cylinder via the secondary air duct. A dust collection pipe is connected to the secondary air duct. The main air separator device blows air into the cylinder through the main air duct, separating light and heavy materials from the material. Heavy materials are less affected by the wind during their descent and are not easily blown away, falling into the heavy material outlet. Light materials are easily blown away, causing lateral displacement and falling from the light material outlet. The suction-type air separator device is located near the material inlet and blows air outward, absorbing light materials during the material's descent and directing them into the light material outlet, thus enhancing the overall air separator's ability to remove light materials.

[0007] According to one aspect of the present invention, a material baffle is provided in the internal cavity of the cylinder; the material baffle is disposed between the heavy material outlet and the light material outlet and is inclined to the side of the light material outlet.

[0008] According to one aspect of the present invention, the main air separator includes a main drive motor and a main fan; the absorption-type air separator includes a secondary drive motor and a secondary fan.

[0009] According to one aspect of this utility model, a first regulating valve is provided on the main air duct; a second regulating valve is provided on the secondary air duct, and the air volume of the main air separator and the suction-type air separator can be adjusted respectively through these two regulating valves.

[0010] According to one aspect of the present invention, a dust collector pipe interface communicating with the internal cavity is provided on the upper part of the cylinder. The dust collector can absorb and collect dust in the material through the interface, reduce impurities in the separated aggregate, and at the same time avoid dust accumulation in the cylinder, which would affect the air separation effect.

[0011] According to one aspect of this utility model, the connection between the cylinder and the heavy material outlet and the light material outlet is conical, narrowing at the outlet to facilitate the collection of light and heavy materials into the next process.

[0012] According to one aspect of this utility model, the cylinder is provided with an inspection door, which is closed and sealed when the air separator is in operation. When the machine is stopped, maintenance personnel can observe the internal condition through the door and, if necessary, enter the cylinder to carry out maintenance and other repair work.

[0013] Advantages of this utility model:

[0014] By installing an absorption-type air separator at the material inlet of the air separator, the main air separator is assisted in separating and screening light substances in the material. The absorption-type air separator absorbs light substances in the material at the beginning of its fall and assists in separating light substances at the point where the wind force of the main air separator weakens. This can effectively reduce the content of light substances in the finished aggregate and improve the quality of the finished aggregate. Attached Figure Description

[0021] The main air separator 3 blows air into the cylinder 1 through the main air duct 2, separating light and heavy materials from the material. The heavy materials are less affected by the wind during the fall and are not easily blown away, falling into the heavy material outlet 12. The light materials are easily blown away, causing lateral displacement and falling from the light material outlet 13. The suction-type air separator 4 is located near the material inlet 11. It blows air outward and absorbs the light materials during the fall of the material, causing them to fall into the light material outlet 13. This enhances the overall effect of the air separator in removing light materials, thereby improving the quality of the finished aggregate. In practical applications, the position and angle of the secondary air duct 5 can be adjusted appropriately to obtain better screening results.

[0022] In practical applications, the main air duct 2 is set at an angle to the side wall of the cylinder 1.

[0023] A material baffle 14 is provided in the internal cavity of the cylinder 1; the material baffle 14 is located between the heavy material outlet 12 and the light material outlet 13 and is inclined to the side of the light material outlet 13 to block the heavy material block splashed towards the light material outlet 13.

[0025] The upper part of the cylinder 1 is provided with a dust collector pipe interface 15 that communicates with the internal cavity.

[0026] Example 2

[0027] like Figure 1 As shown, a novel construction waste air separator includes a cylinder 1, a main air duct 2, and a main air separator 3. The main air separator 3 is connected to the cylinder 1 via the main air duct 2. A material inlet 11 communicating with the inner cavity of the cylinder 1 is provided at the top of the cylinder 1, and a heavy material outlet 12 and a light material outlet 13 communicating with the inner cavity of the cylinder 1 are provided below it. The separator also includes a suction-type air separator 4 and a secondary air duct 5. The suction-type air separator 4 is located on the upper part of the cylinder 1 and connected to the cylinder 1 via the secondary air duct 5. A dust collection pipe 51 is connected to the secondary air duct 5.

[0028] The main air separator 3 blows air into the cylinder 1 through the main air duct 2, separating light and heavy materials from the material. The heavy materials are less affected by the wind during the fall and are not easily blown away, falling into the heavy material outlet 12. The light materials are easily blown away, causing lateral displacement and falling from the light material outlet 13. The suction-type air separator 4 is located near the material inlet 11. It blows air outward and absorbs the light materials during the fall of the material, causing them to fall into the light material outlet 13. This enhances the overall effect of the air separator in removing light materials, thereby improving the quality of the finished aggregate. In practical applications, the position and angle of the secondary air duct 5 can be adjusted appropriately to obtain better screening results.

[0029] In practical applications, the main air duct 2 is set at an angle to the side wall of the cylinder 1. The main air separation device 3 blows air into the internal cavity of the cylinder 1 at an angle upward. The secondary air duct 5 is set at the upper part of the cylinder 1 and close to the material inlet 11. It adopts the suction method, which will not weaken the airflow generated by the main air separation device 3, and works with the latter to improve the removal capacity of light materials.

[0030] In practical applications, a dust collection pipe 51 is connected to the secondary air duct 5 to collect fine dust entering the secondary air duct 5.

[0031] A material baffle 14 is provided in the internal cavity of the cylinder 1.

[0032] The main air separator 3 includes a main drive motor 31 and a main fan 32; the absorption-type air separator 4 includes a secondary drive motor 41 and a secondary fan 42.

[0034] A dust collector pipe interface 15 is provided on the top of the cylinder 1, which communicates with the internal cavity. The dust collector can suck up and collect the dust in the material through this interface, reduce impurities in the separated aggregate, and at the same time prevent dust from accumulating in the cylinder 1 and affecting the air separation effect.

[0035] In practical applications, the connection between the cylinder 1 and the heavy material outlet 12 and the light material outlet 13 is conical. In engineering, the taper of the cone is set between 60-70°, and it narrows at the outlet to facilitate the collection of light and heavy materials into the next process.
