[0027] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Reference Figures 1 to 6 As shown, the present invention provides a construction waste processing device, including: a separation box 1, an air separation device, a crushing box 3, a conveyor belt 4 and a hopper 5.

[0030] In this embodiment, the separation box 1 is a rectangular box. A plurality of legs are provided at the bottom of the box. A first feed port and an exhaust port are provided at the top of the separation box. A light material port 10 and a heavy material port are provided on one side wall of the separation box 1. The heavy material port is provided below the light material port 10. The light material port is used to discharge light materials from construction waste. Light materials include extruded polystyrene boards, non-woven fabrics and other lightweight construction decoration materials. The heavy material port is used to discharge heavy materials from construction waste. Heavy materials include concrete blocks, etc. An air inlet is provided on the other side wall of the separation box 1. The exhaust port is provided between the air inlet and the light material port 10.

[0031] In this embodiment, the air inlet of the separation box corresponds to the position of the light material port. The first material feed port is arranged at one end of the top of the separation box close to the air inlet.

[0032] The air separation device includes an inlet fan 21, an exhaust fan 22, and a scraper 25. The inlet fan is installed in the air inlet and aligned with the light material outlet 10. A filter plate is installed inside the air outlet. The exhaust fan is installed outside the air outlet. The scraper is adjustable in position within the separation box 1. The exhaust fan draws light materials from the construction waste, causing them to be adsorbed on the filter plate 25. The scraper is adjusted in position to remove light materials from the filter plate, allowing them to be discharged through the light material outlet 10 under the wind force of the inlet fan.

[0033] The air separation device is used to separate the light materials from the heavy materials in the engineering waste by using wind force during the falling process after the engineering waste is put into the first feeding port, blow away the light materials in the heavy materials by wind force, and then use the wind force in the exhaust port to absorb the light materials, thereby separating the light materials from the heavy materials. Finally, by adjusting the position of the scraper plate, the scraper plate is used to scrape off the light materials adsorbed on the filter plate, and the light materials are blown into the light material port and discharged from the separation box by the wind force of the inlet fan in the air inlet.

[0034] The crushing box 3 is arranged opposite to the separation box 1. A second feed opening is opened on the upper part of the crushing box 3.

[0035] The conveyor belt 4 has an input end and an output end. The input end of the conveyor belt 4 is arranged below the first feed opening. The output end of the conveyor belt 4 passes through the heavy material opening and extends into the second feed opening of the crushing box 3.

[0036] As a preferred embodiment, see Figure 2 The construction waste treatment equipment of the present invention further comprises a hopper 5. The hopper 5 has an upper hopper opening and a lower hopper opening. The lower hopper opening of the hopper 5 is connected to the first feed port of the separation box. A first roller 53 is installed below the upper hopper opening of the hopper 5. Figure 5 The first roller 53 is formed with at least three first material baffles 54 arranged along its circumference. Each of these first material baffles 54 has multiple chip removal holes. Two adjacent first material baffles 54 enclose a first material receiving trough. Construction waste is dropped into the first receiving trough through the upper hopper opening, where finer impurities such as dust in the waste are first removed through the chip removal holes.

[0037] In some embodiments, a material control motor is mounted on the exterior of the separation box. The material control motor is connected to the first roller. The rotational speed of the material control motor controls the rotational speed of the first material baffle to control the falling speed of the construction waste introduced through the upper hopper opening, thereby preventing a large amount of construction waste from being introduced at once and clogging the hopper.

[0038] Continue reading Figure 2 The lower bucket is equipped with an extrusion device for squeezing large waste materials in engineering waste.

[0039] Specifically, the extrusion device includes two extrusion rollers 51. The two extrusion rollers 51 are arranged in the same direction. They are formed with multiple crushing teeth. The crushing teeth on the two extrusion rollers are staggered. The extrusion rollers 51 are rotatable in the underground hopper. A compression space is formed between the two extrusion rollers 51. Larger pieces of construction waste are initially crushed under the pressure of the two extrusion rollers and continue to fall.

[0040] In this embodiment, a guide block 52 is installed between the opposite sides of the two squeezing rollers 51 and the sidewall of the lower hopper opening. The top of the guide block 52 forms a sloped surface. The upper end of the sloped surface is connected to the sidewall of the lower hopper opening. The lower end of the sloped surface extends to the opposite side of the squeezing rollers 51. The sloped surface of the guide block guides the construction waste into the squeezing space between the two squeezing rollers.

[0041] In this embodiment, a second roller is disposed below the first feed port of the separation box. The second roller is rotatably mounted within the separation box. The second roller and the first roller are arranged in the same horizontal direction. The second roller 11 is formed with at least three second material retaining plates 12 arranged along the circumference of the second roller 11. Adjacent second material retaining plates 12 enclose a second material receiving chute. The second roller 11 is positioned above the input port.

[0042] In this embodiment, there are three first material baffles and three second material baffles, and the first and second material baffles are arranged at equal intervals.

[0043] Continue reading Figure 2 A spray device 13 is installed in the separation box 1. It is aligned with the center of the conveyor belt 4 and is located between the light material port 10 and the heavy material port. After entering the hopper, construction waste undergoes initial crushing and air separation. The light material is discharged through the light material port, while the heavy material falls into the secondary receiving trough and onto the input end of the conveyor belt, where it is transported through the conveyor belt and crushing box. During the conveyance of the heavy material, the spray device sprays dust removal fluid onto the heavy material on the conveyor belt, reducing the amount of dust entering the crushing box.

[0044] As a preferred embodiment, a dust removal box 14 is installed on the outside of the separation box 1. The dust removal box 14 is used to accommodate dust removal liquid. In this embodiment, the dust removal liquid is clean water. The exhaust port is connected to a delivery pipe 141. The delivery pipe 141 extends into the dust removal liquid. Specifically, the delivery pipe has a first end and a second end relative to each other. The first end of the delivery pipe is connected to an air collection hood. The air collection hood is connected to the outside of the exhaust port, so that the airflow sucked by the exhaust fan is transported through the delivery pipe to the dust removal liquid in the dust removal box for dust washing, so that the dust in the airflow sucked by the exhaust fan is adsorbed by the dust removal liquid.

[0045] In this embodiment, see Figure 3 , a filter screen 142 is installed in the dust removal box 14. The filter screen 142 is arranged between the conveying pipe 141 and the bottom of the dust removal box 14. A water pump 145 is installed at the bottom of the dust removal box 14. The water pump 145 is connected to the spray device 13 through a water pipe 146. In some embodiments, the spray device includes a spray pipe and a plurality of nozzles. The spray pipe is arranged along the length direction of the conveyor belt. A plurality of nozzles are installed on the spray pipe. The plurality of nozzles are arranged at intervals along the length direction of the spray pipe. After the water pump transports the dust removal liquid to the spray pipe through the water pipe, the dust removal liquid is sprayed onto the heavy material on the conveyor belt through the nozzle.

[0046] The filter retains the flocculent impurities on the upper part of the filter, so that the dust removal liquid at the bottom of the filter can remain relatively clean. Then the dust removal liquid at the bottom of the filter can be pressurized and transported to the spray device through a water pump and a water pipe for reuse to remove dust from heavy materials on the conveyor belt.

[0047] Filter 142 is mounted on the top of dust box 14 so that it can be raised and lowered by an electric hydraulic push rod 143. A dust collector 144 is mounted on the upper side of dust box 14. When electric hydraulic push rod 143 retracts to raise filter 142, filter 142 comes into contact with dust collector 144, which removes impurities from filter 142.

[0048] In the separation box, a chute is formed on the side wall of the separation box. A slider slides in the chute. A hydraulic cylinder is mounted at one end of the chute. The hydraulic cylinder is arranged along the length of the chute. The slider is connected to the telescopic end of the hydraulic cylinder. The electric hydraulic push rod has a fixed end and a telescopic end. The electric hydraulic push rod is arranged vertically. The scraper plate is connected to the telescopic end of the electric hydraulic push rod. When light material needs to be scraped off the filter plate, the electric hydraulic push rod is extended, causing the scraper plate to abut the filter plate. The hydraulic cylinder then extends, causing the scraper plate to push the light material along the length of the filter plate toward the light material outlet, thereby separating the light material from the filter plate and entering the light material outlet.

[0049] A discharge port is provided at the bottom of the crushing box 3. Two crushing rollers 31 arranged in the same direction are installed in the discharge port. The crushing box 3 is provided with a first motor 32 for driving the crushing rollers 31.

[0050] In this embodiment, a first motor is mounted outside the crushing box. The output shaft of the first motor is coaxially connected to a crushing roller. A driving gear is coaxially mounted on one crushing roller. A transmission gear is rotatably mounted on the side wall of the crushing box. A driven gear is coaxially mounted on the other crushing roller. Opposite sides of the transmission gear are respectively engaged with the driving gear and the driven gear.

[0051] The structure of the crushing roller is the same as that of the squeezing roller. The first spacing between the two squeezing rollers in the hopper is larger, while the second spacing between the two crushing rollers in the crushing box is smaller. Specifically, the first spacing is larger than the second spacing.

[0052] The construction waste processing equipment of the present invention uses wind power to separate the light materials and heavy materials in the construction waste by using the separation box, wherein the exhaust fan sucks the airflow inside the separation box, which can, on the one hand, gather the light materials and adsorb them on the filter plate, and on the other hand, effectively extract the dust. The airflow that extracts and carries the dust is introduced into the dust removal liquid in the dust removal box through the conveying pipe for purification. The light materials adsorbed on the filter plate are sent to the light material port by the wind power of the inlet fan for discharge after being scraped by the scraper plate, and the heavy materials are conveyed to the crushing box by the conveyor belt for further crushing. The construction waste processing equipment of the present invention cooperates with the separation box, the air separation device, the conveyor belt and the crushing box to separate the lighter decoration waste and gravel before the crushing operation. After the overall waste is crushed, it can be directly recycled, which improves the crushing effect and crushing quality, and further reduces the difficulty of subsequent processing.

[0053] The construction waste treatment equipment of the present invention performs dust reduction treatment on the interior of the separation box through the coordinated cooperation of the spray device and the dust removal box, so that after the heavy material is sprayed and moistened, dust generation is reduced during the subsequent crushing process in the crushing box, and the dust on the filter net is sucked and discharged by the vacuum cleaner and recovered in a unified manner. The effective waste treatment process generates a large amount of dust for processing, protects the health of the staff, and prevents the environment from being affected.
