[0002] With the increasing scarcity of natural aggregate resources, the comprehensive utilization of solid waste resources under the circular economy model has become an inevitable path. Unlike the traditional linear economic development model, its purpose is to form a closed-loop feedback green development of "resources-products-recycled resources".

[0003] Due to the complex composition of solid waste, only by classifying it can resource utilization be achieved. Therefore, the classification and treatment of solid waste is more urgent. Currently, the classification methods for solid waste include:

[0004] End-of-line sorting refers to the professional and centralized classification of solid waste using mechanical methods at solid waste sorting sites. Commonly used mechanical sorting methods include screening, gravity air separation, elastic and frictional separation, magnetic separation, and electrostatic separation. However, some steps in the sorting process still require manual assistance.

[0016] A rectangular groove is formed on the inner wall of the machine body, and the filter plate is slidably connected inside the rectangular groove. A spring is installed inside the rectangular groove, and the spring is located at the lower end of the filter plate.

[0017] A chute is formed inside the machine body, with its upper end connected to the cylindrical groove and its lower end connected to the rectangular groove. A slider is slidably connected inside the chute, with its upper end located inside the cylindrical groove. When the first grinding roller rotates, the triangular block presses against the upper end of the slider, and the lower end of the slider contacts the upper end of the filter plate.

[0018] As a preferred embodiment of this application, when the filter plate moves to the position closest to the first discharge port, the conveyor belt is located at the lower end of the filter plate.

[0019] As a preferred embodiment of this application, a hinge rod is hinged to the inner wall of the machine body. The hinge rod is located at the upper end of the filter plate. A metal filter screen is provided at the upper end of the filter plate. The metal filter screen is hinged to the lower end of the hinge rod. In the initial state, the included angle between the hinge rod and the filter plate is less than 90°.

[0020] As a preferred embodiment of this application, a fixing plate is provided at the lower end of the rectangular groove, and a rectangular block is provided at the upper end of the fixing plate. The rectangular block has a cavity inside, and a connecting block is slidably connected inside the rectangular block. The outer ring of the connecting block is sealed to achieve a sealed sliding connection between the connecting block and the cavity inside the rectangular block. A through hole is provided inside the connecting block, the lower end of which communicates with the cavity inside the rectangular block, and the upper end of which penetrates through the upper end of the connecting block.

[0021] As a preferred embodiment of this application, the conveyor belt is provided with rectangular through grooves evenly distributed, and a screening plate is hinged inside the rectangular through grooves. The screening plate is hinged inside the rectangular through grooves by a torsion spring.

[0022] As a preferred embodiment of this application, the screening plate is configured in multiple segments, and each segment on the screening plate is in contact with each other.

[0023] As a preferred embodiment of this application, there is a gap between the conveyor belt and the second discharge port, and an air outlet is provided at the lower end of the second discharge port. A blower is installed inside the air outlet, and the air outlet is inclined upward.

[0024] A method for air-separation treatment of construction waste for resource recovery, applicable to any of the aforementioned air-separation treatment devices for construction waste resource recovery; the method includes the following steps:

[0025] S1: First, the staff needs to put the garbage into the machine through the feed port. The two No. 1 grinding rollers will rotate to crush the garbage and grind it into block particles. After grinding, the block particles fall from the part between the two No. 1 grinding rollers.

[0026] S2: Based on S1, the exhaust fan blows the waste that has been ground and fallen between the No. 1 grinding rollers in real time. The heavier glass block particles fall downwards onto the filter plate, while the lighter waste is blown away from the exhaust fan by the wind and falls onto the conveyor belt. Then, the exhaust fan blows the light impurities and the conveyor belt moves to carry the light impurities, thereby realizing the conveying of paper and wood light impurities from the No. 2 discharge port.

[0027] S3: Based on S2, when heavy glass impurities fall onto the filter plate, the triangular block set on the shaft of the first grinding roller rotates with the first grinding roller. The inclined surface on the triangular block will squeeze the slider, and the slider will move downward inside the groove to squeeze the filter plate below. The filter plate slides downward inside the rectangular groove. Then, when the triangular block passes the upper end of the slider during rotation, the filter plate is reset by the spring and slides upward. At this time, it is convenient for the light impurities that have fallen on the filter plate to vibrate and bounce up, so that the exhaust fan can blow the light impurities towards the conveyor belt.

[0028] S4: Based on S3, after glass impurities fall onto the filter plate, the glass continues to fall downwards after staying on the filter plate. This allows heavier glass impurities to fall into the first discharge port. Subsequently, the second grinding roller inside the first discharge port finely grinds the particulate impurities, resulting in a significant reduction in the volume of the broken glass after grinding. This brings convenience to the storage, transportation, and processing of glass waste.

[0029] The beneficial effects of this invention are as follows:

[0030] When glass and other impurities fall onto the filter plate, they remain on the plate before continuing to fall downwards. Heavier impurities, such as glass, fall into the first discharge port, where a second grinding roller further grinds the particles. This significantly reduces the volume of the crushed glass, facilitating the storage, transportation, and processing of glass waste. The crushed glass also facilitates subsequent recycling. Furthermore, it mixes better with other materials for the production of glass products, fiberglass, and building materials. The larger surface area of ​​the crushed glass improves the efficiency and quality of reuse, while also reducing environmental pollution. Attached Figure Description

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] With the increasing scarcity of natural aggregate resources, the comprehensive utilization of solid waste resources under the circular economy model has become an inevitable path. Unlike the traditional linear economic development model, its purpose is to form a closed-loop feedback green development of "resources-products-recycled resources".

[0042] Due to the complex composition of solid waste, only by classifying it can resource utilization be achieved. Therefore, the classification and treatment of solid waste is more urgent. Currently, the classification methods for solid waste include:

[0043] End-of-line sorting refers to the professional and centralized classification of solid waste using mechanical methods at solid waste sorting sites. Commonly used mechanical sorting methods include screening, gravity air separation, elastic and frictional separation, magnetic separation, and electrostatic separation. However, some steps in the sorting process still require manual assistance.

[0044] In modern life, residents have high requirements for their living environment, which has created a large market for the home renovation industry. However, the home renovation process, especially the redecoration of a house, generates a large amount of construction waste, such as paper, glass, and plastic waste. When cleaning and recycling this construction waste, waste collectors need to manually sort it to achieve waste classification; automation is inefficient and not conducive to large-scale recycling.

[0045] A construction waste recycling and air separation processing device includes a body 1, with a feed inlet 11 at the upper end and a discharge outlet 12 at the lower end of the body 1; the body 1 is internally equipped with:

[0046] There are two No. 1 grinding rollers 13, and each No. 1 grinding roller 13 is rotated by a motor installed at one end; the No. 1 grinding roller 13 is used for pre-grinding.

[0047] The second grinding roller 14 is located at the position of the first discharge port 12. The second grinding roller 14 is located at the position of the first discharge port 12 and is rotated by a motor at one end. The second grinding roller 14 is used for fine grinding.

[0048] The filter plate 15 is located directly below the feed inlet 11. Filter holes are evenly distributed on the filter plate 15. A vibration unit 2 is provided between the filter plate 15 and the first grinding roller 13.

[0049] The conveyor belt 3 is disposed on one side of the filter plate 15 and is located obliquely below the feed inlet 11; and the lower end of the conveyor belt 3 is provided on the inclined surface of the inner wall of the machine body 1.

[0050] The second discharge port 16 is located on the side of the machine body 1 and is located at the end of the conveyor belt 3 away from the filter plate 15.

[0051] The exhaust fan 17 is located on the side wall of the machine body 1 away from the second discharge port 16, and the horizontal height of the exhaust fan 17 is higher than that of the filter plate 15.

[0052] The vibration unit 2 includes:

[0053] A cylindrical groove 21 is formed inside the machine body 1, and the rotating shaft at the end of the first grinding roller 13 extends into the center of the cylindrical groove 21. A triangular block 22 is provided on the rotating shaft of the first grinding roller 13, and the triangular block 22 is located inside the cylindrical groove 21.

[0054] A rectangular groove 23 is formed on the inner wall of the machine body 1. The filter plate 15 is slidably connected inside the rectangular groove 23. A spring is provided inside the rectangular groove 23, and the spring is located at the lower end of the filter plate 15.

[0055] A chute 24 is formed inside the machine body 1, with its upper end connected to the cylindrical groove 21 and its lower end connected to the rectangular groove 23. A slider 25 is slidably connected inside the chute 24, with its upper end located inside the cylindrical groove 21. When the first grinding roller 13 rotates, the triangular block 22 presses against the upper end of the slider 25, and the lower end of the slider 25 contacts the upper end of the filter plate 15.

[0056] When the filter plate 15 moves to the position closest to the first discharge port 12, the conveyor belt 3 is located at the lower end of the filter plate 15;

[0057] The specific workflow is as follows;

[0058] A material inlet is provided at the upper end of the machine body 1. Two No. 1 grinding rollers 13 are installed inside the inlet 11, rotating in opposite directions. When waste collectors collect waste, they first place the waste into the machine body 1 through the inlet 11. Before the waste enters the machine body 1, the two No. 1 grinding rollers 13 rotate to crush the waste, pre-grinding it into granular particles. The crushed particles fall from between the two No. 1 grinding rollers 13. A filter plate 15 is installed inside the machine body 1, located directly below the inlet 11. As the crushed waste falls between the two No. 1 grinding rollers 13, an exhaust fan 17 is installed at the end furthest from the No. 2 outlet 16. The exhaust fan 17 continuously blows the crushed waste that has fallen between the No. 1 grinding rollers 13. During the waste falling process, the exhaust fan 17... 7. The waste is blown, and at this time, waste such as glass, paper and wood are mixed together. At this time, the heavier waste such as glass and other blocky particles fall downward onto the filter plate 15, while the lighter waste such as wood and paper is blown by the exhaust fan 17. The lighter waste will be blown away from the exhaust fan 17 by the wind force. At this time, a conveyor belt 3 is set inside the machine body 1, and the end of the conveyor belt 3 away from the filter plate 15 is located at the end of the second feed port 11. The conveyor belt 3 is located diagonally below the feed port 11. When the light waste is blown away from the exhaust fan 17 by the wind force, the light waste will fall onto the conveyor belt 3. Then the conveyor belt 3 is rotated by a motor set at one end. The conveyor belt 3 carries the light impurities towards the second discharge port 16. Then the exhaust fan 17 blows the light impurities and the conveyor belt 3 moves the light impurities, thereby realizing the conveying of light impurities such as paper and wood from the second discharge port 16.

[0059] When glass and other heavy impurities fall onto the filter plate 15, a cylindrical groove 21 is opened inside the machine body 1, and the shaft of the first grinding roller 13 extends into the cylindrical groove 21. A triangular block 22 is set on the shaft of the first grinding roller 13. When the first grinding roller 13 rotates, the triangular block 22 on the shaft of the first grinding roller 13 rotates with the first grinding roller 13. A sliding groove 24 is opened inside the machine body 1, with the upper end of the sliding groove 24 communicating with the cylindrical groove 21 and the lower end of the sliding groove 24 communicating with the rectangular groove 23. The filter plate 15 is slidably connected inside the rectangular groove 23. A slider 25 is slidably connected inside the sliding groove 24, and the upper end of the slider 25 extends into the cylindrical groove 21. When the triangular block 22 rotates with the first grinding roller 13, the inclined surface of the triangular block 22 will squeeze the slider 25. After being squeezed, the slider 25 will move downward inside the sliding groove 24. During the downward movement, the slider 25 presses against the filter plate 15 below. After being pressed, the filter plate 15 slides downward inside the rectangular groove 23, and the spring inside the rectangular groove 23 is compressed. Then, when the triangular block 22 passes over the upper end of the slider 25 during rotation, the filter plate 15 is reset by the spring and slides upward inside the rectangular groove 23. As the filter plate 15 vibrates up and down inside the rectangular groove 23, the glass particles on the filter plate 15 vibrate. This makes it easier for light impurities that have fallen on the filter plate 15 to bounce up, so that the exhaust fan 17 can blow the light impurities toward the conveyor belt 3. When the filter plate 15 is in the direction closest to the first feed port 11, the horizontal height of the conveyor belt 3 is lower than that of the filter plate 15, so that light impurities can enter the conveyor belt 3 on the filter plate 15. Thus, it can automatically separate light impurities such as paper, wood, and glass from heavier impurities.

[0060] When glass and other impurities fall onto the filter plate 15, they remain on the filter plate 15 and continue to fall downwards, allowing heavier impurities to fall into the first discharge port 12. The second grinding roller 14 inside the first discharge port 12 then finely grinds the particulate impurities, significantly reducing the volume of the broken glass. This facilitates the storage, transportation, and processing of glass waste. Grinding the broken glass facilitates subsequent recycling. The ground glass can be better mixed with other materials for the production of glass products, glass fibers, building materials, etc. Furthermore, the ground glass has a larger surface area, improving the efficiency and quality of reuse. It also reduces environmental pollution: large, untreated pieces of glass waste easily cause environmental pollution. Grinding the broken glass effectively reduces sharp edges and protrusions in the waste, reducing the risk of injury caused by improper handling of broken glass. In addition, grinding the broken glass also reduces its scattering and splashing in the environment.

[0061] Example 2:

[0062] The inner wall of the machine body 1 is hinged with a hinge rod 18, which is located at the upper end of the filter plate 15. A metal filter screen 19 is provided at the upper end of the filter plate 15. The metal filter screen 19 is hinged to the lower end of the hinge rod 18, and in the initial state, the included angle between the hinge rod 18 and the filter plate 15 is less than 90°.

[0063] A fixing plate 231 is provided at the lower end of the rectangular groove 23, and a rectangular block 232 is provided at the upper end of the fixing plate 231. The rectangular block 232 has a cavity inside, and a connecting block 234 is slidably connected inside the rectangular block 232. The outer ring of the connecting block 234 is sealed to achieve a sealed sliding connection between the connecting block 234 and the cavity inside the rectangular block 232. A through hole 235 is provided inside the connecting block 234. The lower end of the through hole 235 communicates with the cavity inside the rectangular block 232, and the upper end of the through hole 235 penetrates the upper end of the connecting block 234.

[0064] The specific workflow is as follows;

[0065] A hinge rod 18 is hinged to the inner wall of the machine body 1, and the hinge rod 18 is located at the upper end of the filter plate 15. A metal filter screen 19 is provided at the upper end of the filter plate 15, and the metal filter screen 19 is slidably connected to the upper end of the filter plate 15. The lower end of the hinge rod 18 is hinged to the upper end of the metal filter plate 15. In the initial state, the included angle between the hinge rod 18 and the filter plate 15 is less than 90°. Based on the first embodiment, when the filter plate 15 vibrates up and down inside the rectangular groove 23, the hinge rod 18 and the filter plate... When the distance between 15 changes, the filter plate 15 drives the metal filter screen 19 to slide on the filter plate 15. When glass impurities fall onto the metal filter screen 19 at the top of the filter plate 15, the metal filter screen 19 vibrates up and down while sliding on the filter plate 15, which turns the glass particles on the filter plate 15 over. At the same time, the exhaust fan 17 blows, which can fully separate paper impurities and wood particles from heavier impurities such as glass, thereby improving the separation efficiency.

[0066] Furthermore, a fixing plate 231 is installed at the lower end of the rectangular groove 23, and a rectangular block 232 is installed at the upper end of the fixing plate 231. The rectangular block 232 has a cavity inside, and a connecting block 234 is slidably connected inside the cavity. The upper end of the connecting block 234 is connected to the filter plate 15, and a through hole 235 is opened on the connecting block 234. When the filter plate 15 vibrates up and down inside the rectangular groove 23, the lower end of the filter plate 15 will squeeze the connecting block 234. When the connecting block 234 slides inside the cavity inside the rectangular block 232, the air pressure inside the cavity will change, and the gas inside the cavity will change. The gas will be ejected through the through hole 235 inside the connecting block 234. Since the upper end of the connecting block 234 is connected to the lower end of the filter plate 15, when the gas inside the through hole 235 is ejected, the gas will be ejected upward from the lower end of the filter plate 15. This allows the gas to be ejected from the lower end of the filter plate 15 when the filter plate 15 vibrates and the metal filter screen 19 slides on the upper surface of the filter plate 15, blowing up the light impurities on the filter plate 15. Then, the air blown out by the exhaust fan 17 blows the paper and wood impurities to the position of the conveyor belt 3, thereby achieving full separation of heavier impurities such as glass from the light impurities.

[0067] Example 3:

[0068] The conveyor belt 3 is provided with rectangular through grooves 31 evenly distributed. A screening plate 32 is hinged inside the rectangular through groove 31. The screening plate 32 is hinged inside the rectangular through groove 31 by a torsion spring.

[0069] The screening plate 32 is configured in multiple segments, and each segment on the screening plate 32 is in contact with each other;

[0070] The specific workflow is as follows;

[0071] By setting a rectangular trough 31 on the conveyor belt 3 and setting a screening plate 32 inside the rectangular trough 23, and making the screening plate 32 hinged inside the rectangular trough 23 by a torsion spring, when the screening plate 32 is located on the upper and lower sides of the conveyor belt 3, the screening plate 32 is parallel to the horizontal plane. After the first grinding roller 13 and the second grinding roller 14 pre-grind the decoration waste, the weight of glass impurities is greater than that of paper impurities. After the glass, paper and wood boards pass through the first grinding roller 13, the exhaust fan 17 blows them. The exhaust fan 17 blows the falling impurities. Hard impurities such as glass particles will fall onto the filter plate 15. When the exhaust fan 17 passes individual hard impurities that fall onto the conveyor belt 3, because the particle size of the glass impurities is different from that of the paper and wood, the glass impurities will fall onto the filter plate 15. The impurities tend to be of similar size, and the glass impurities are heavy. Therefore, when paper and wood impurities fall onto the conveyor belt 3, their weight is insufficient to rotate the screening plate 32, allowing the conveyor belt 3 to transport the wood and paper impurities out of the second discharge port 16. When heavy impurities such as glass fall onto the conveyor plate, the screening plate 32 will rotate due to gravity, allowing the glass impurities to fall off the conveyor belt 3. Furthermore, by setting the screening plate 32 in multiple segments, with each screening plate 32 in contact with the others, when glass and other impurities fall, the screening plate 32 below the heavier impurities rotates, preventing the entire screening plate 32 from rotating. This avoids the lighter impurities falling off the screening plate 32 on the conveyor belt 3 when the entire screening plate 32 rotates.

[0072] Example 4:

[0073] There is a gap between the conveyor belt 3 and the second discharge port 16. The lower end of the second discharge port 16 is provided with an air outlet 161. A blower 162 is installed inside the air outlet 161, and the air outlet 161 is inclined upward to blow air.

[0074] The specific workflow is as follows;

[0075] By creating a gap between the conveyor belt 3 and the second discharge port 16, and by providing an air outlet 161 at the lower end of the second discharge port 16, with a blower 162 installed inside the air outlet 161, and by positioning the blower 162 to blow upwards at an angle, based on Embodiment 3, when impurities such as glass fall onto the conveyor belt 3, as the conveyor belt 3 rotates, when the impurities move to the end of the conveyor belt 3 near the second discharge port 16, they will fall from the conveyor belt 3 into the gap between the conveyor belt 3 and the lower end of the second discharge port 16, thus allowing the impurities to enter the first discharge port. The discharge port 12 is ground by the second grinding roller 14; however, paper and light impurities are blown by the exhaust fan 17, and by setting an air outlet 161 at the lower end of the second discharge port 16, and the air outlet 161 is inclined upward, and a blower 162 is set at the lower end of the air outlet 161, the blower 162 makes the air outlet 161 blow outward, thereby realizing that the exhaust fan 17 and the blower 162 can prevent paper and wood impurities from falling from the gap between the conveyor belt 3 and the second discharge port 16; thus realizing that paper and wood impurities are discharged from the second discharge port 16.

[0076] Example 5:

[0077] A method for air-separation treatment of construction waste for resource recovery, applicable to any of the aforementioned air-separation treatment devices for construction waste resource recovery; the method includes the following steps:

[0078] S1: First, the staff needs to put the garbage into the machine body 1 through the feed port 11. The two No. 1 grinding rollers 13 will rotate to crush the garbage and grind it into block particles. After grinding, the block particles fall from the part between the two No. 1 grinding rollers 13.

[0079] S2: Based on S1, the exhaust fan 17 blows the waste that has been ground and fallen between the first grinding roller 13 in real time. The heavier waste such as glass and other blocky particles fall downward onto the filter plate 15, while the lighter waste will be blown away from the exhaust fan 17 by the wind and fall onto the conveyor belt 3. Then the exhaust fan 17 blows the light impurities and the conveyor belt 3 moves to drive the light impurities, thereby realizing the conveying of light impurities such as paper and wood from the second discharge port 16.

[0080] S3: Based on S2, when heavy impurities such as glass fall onto the filter plate 15, the triangular block 22 set on the shaft of the first grinding roller 13 rotates with the first grinding roller 13. The inclined surface on the triangular block 22 will squeeze the slider 25. The slider 25 will move downward inside the slide groove 24 to squeeze the filter plate 15 below. The filter plate 15 slides downward inside the rectangular groove 23. Then, when the triangular block 22 passes the upper end of the slider 25 during rotation, the filter plate 15 slides upward under the spring reset action. At this time, it is convenient for the light impurities that fall on the filter plate 15 to vibrate and bounce up, so that the exhaust fan 17 can blow the light impurities towards the direction of the conveyor belt 3.

[0081] S4: Based on S3, after glass and other impurities fall onto the filter plate 15, the glass will continue to fall downwards after staying on the filter plate 15, thus enabling heavier impurities such as glass to fall into the first discharge port 12. Subsequently, the second grinding roller 14 inside the first discharge port 12 will finely grind the particulate impurities, so that the volume of the broken glass will be greatly reduced after the grinding process; this brings convenience to the storage, transportation and treatment of glass waste.

6. A method for air-separation treatment of construction waste for resource recovery, the method being applicable to the air-separation treatment equipment for construction waste resource recovery described in any one of claims 1-5; characterized in that: The method includes the following steps: S1: First, the staff needs to put the garbage into the machine body (1) through the feed port (11). The two No. 1 grinding rollers (13) will rotate to crush the garbage and grind it into block particles. After grinding, the block particles fall from the part between the two No. 1 grinding rollers (13). S2: Based on S1, the exhaust fan (17) blows the waste that has been ground and fallen between the first grinding roller (13) in real time. The heavy waste of glass block particles falls down onto the filter plate (15), and the light waste will be blown away from the exhaust fan (17) by the wind. The light waste will fall onto the conveyor belt (3). Then the exhaust fan (17) blows the light impurities and the conveyor belt (3) moves to drive the light impurities, thereby realizing the conveying of paper and wood light impurities from the second discharge port (16). S3: Based on S2, when glass impurities fall onto the filter plate (15), the triangular block (22) set on the shaft of the first grinding roller (13) rotates with the first grinding roller (13). The inclined surface on the triangular block (22) will squeeze the slider (25). The slider (25) will move downward inside the slide groove (24) to squeeze the filter plate (15) below. The filter plate (15) slides downward inside the rectangular groove (23). Then, when the triangular block (22) passes over the upper end of the slider (25) during rotation, the filter plate (15) slides upward under the spring reset action. At this time, it is convenient for the light impurities that fall on the filter plate (15) to vibrate and bounce up, so that the exhaust fan (17) can blow the light impurities towards the direction of the conveyor belt (3). S4: Based on S3, after the glass impurities fall onto the filter plate (15), the glass will continue to fall downwards after staying on the filter plate (15), so that the heavier glass impurities fall into the first discharge port (12). Then, the second grinding roller (14) inside the first discharge port (12) will finely grind the particulate impurities, so that the volume of the broken glass will be greatly reduced after the grinding process. This brings convenience to the storage, transportation and treatment of glass waste.
