Description

Technical Field

[0001] This invention relates to an environmentally friendly treatment device, and more particularly to an intelligent environmentally friendly treatment device for construction waste. This invention also relates to an environmentally friendly treatment method, and more particularly to an intelligent environmentally friendly treatment method for construction waste, belonging to the field of construction waste treatment technology. Background Technology

[0002] Currently, in the environmental protection process of construction waste treatment, negative pressure air separators are often used to separate packaging waste such as lightweight plastic bags and cement bags. They use negative pressure adsorption to initially separate lightweight plastics from heavy waste, which facilitates the recycling and reuse of plastic waste.

[0003] However, in actual construction scenarios, lightweight packaging waste such as plastic bags and cement bags are easily damaged or left in a semi-closed state due to squeezing and collision during loading, transportation, and unloading. This makes it easy for heavy impurities such as concrete debris and sand to become embedded in or encased in the bag. Even if the negative pressure air separator can pick them up, it cannot remove the concrete, sand, and other impurities encased inside the lightweight waste. As a result, the purity of the separated plastic waste is low, and the cleaning effect is poor. The impurities still need to be picked out from the plastic waste manually, which is not only labor-intensive and inefficient, but also significantly increases the processing cost.

[0004] Therefore, an intelligent and environmentally friendly treatment device and method for construction waste is designed to optimize the above-mentioned problems. Summary of the Invention

[0005] The main objective of this invention is to provide an intelligent and environmentally friendly treatment device and method for construction waste. By installing a conical guide block at the top of the separation cylinder, the injected construction waste is rapidly diffused outwards, ensuring a uniform flow of waste across the outer wall of the conical sleeve. Combined with a conveyor belt arranged circumferentially on the outer wall of the conical sleeve and hanging rods on the outer side, the conveyor belt drives the hanging rods upwards during the natural descent of the waste. This accurately catches and transports lightweight packaging waste such as plastic bags and cement bags upwards. Furthermore, the conveying path works synergistically with the cutting blades at the bottom of the conical guide block to efficiently handle the bags. The cutting action completely removes and discharges the heavy impurities such as concrete debris and gravel trapped inside the bag. As the hanging rod passes through the groove at the top of the discharge pipe, it intercepts the lightweight waste after impurity removal and directs it into the discharge pipe for centralized discharge. This effectively reduces the amount of residual impurities in the lightweight waste, eliminating the need for manual sorting and significantly improving the purity and cleaning efficiency of the recycled lightweight waste. The bottom of the conical guide block is connected to the conical sleeve by a spring and a sliding rod, causing the conical guide block to vibrate up and down when impacted by waste. This, combined with the cutting blade, further enhances the cutting effect on the lightweight waste bag. To ensure more thorough impurity removal, the bottom end of the vertical rod, linked to the conical guide block, passes through the discharge pipe and connects to the screen plate. During the shaking of the conical guide block, it synchronously drives the screen plate to vibrate, achieving graded screening of detached heavy impurities and improving the equipment's functionality. Furthermore, the pressure block at the top of the vertical rod presses light waste downwards during the up-and-down shaking, preventing the bag from accumulating at the top. Meanwhile, the serrated blades arranged along the length of the bottom of the vertical rod cut off the light waste intercepted at the bottom, effectively preventing blockage of the discharge pipe, ensuring continuous and stable operation of the equipment, and further enhancing the overall processing capacity. Efficiency is achieved through the coordinated operation of various components, realizing the automated separation of lightweight packaging waste and internal impurities in construction waste, the grading and screening of heavy components, and the anti-clogging guarantee of equipment operation. The entire process requires minimal manual intervention, which not only reduces labor intensity and cost but also significantly shortens the processing time. At the same time, the improved purity of lightweight waste recycling and the graded recycling of heavy impurities increase the resource utilization rate of construction waste and reduce waste emissions. This not only meets environmental protection requirements but also realizes resource recycling, fully satisfying the treatment needs of construction waste.

[0006] The objective of this invention can be achieved by adopting the following technical solution: A smart and environmentally friendly construction waste treatment device includes a frame, a screening box, a separation cylinder, and a drive mechanism. The screening box is fixed to the top of the frame, and the separation cylinder is fixedly installed above the screening box and communicates with the inside of the screening box. A feed hopper is provided at the top of the separation cylinder, and a conical base is fixed at the bottom of the separation cylinder. A conical sleeve is fixedly fitted on the top of the conical base. Several strip grooves are provided on the outer wall of the conical sleeve along the circumferential direction. Conveying rollers are rotatably installed at both the upper and lower ends inside the strip grooves. A conveyor belt is fitted on the outer side of the conveyor rollers, and several hanging rods are fixed at intervals on the outer wall of the conveyor belt. A conical guide block is movably installed at the top of the separator cylinder. Several slicing blades are evenly fixed at the bottom of the conical guide block along the circumference, and the bottom of the slicing blades corresponds to the conveying path of the conveyor belt. The cone sleeve has a discharge pipe inside, which passes through the cone-shaped base and extends to the outside of the separator. The top of the discharge pipe has a groove that matches the hanging rod. A vertical rod is fixed at the center of the bottom of the conical guide block. The bottom end of the vertical rod slides through the discharge pipe and extends into the screening box, where it is connected to a screen plate. The drive mechanism is installed inside the conical base and is connected to the conveyor rollers.

[0007] Preferably, a sliding rod is evenly provided between the bottom of the conical guide block and the top of the conical sleeve. A second spring is sleeved on the outside of each sliding rod, and the two ends of the second spring are fixedly connected to the conical guide block and the conical sleeve, respectively. The sliding rod is slidably connected to the conical guide block and fixedly connected to the conical sleeve.

[0008] Preferably, a pressure block is fixed at the top of the vertical rod, a serrated blade is provided at the bottom of the vertical rod along its length, and a through hole that mates with the vertical rod and a groove that mates with the serrated blade are provided at the bottom of the discharge pipe.

[0009] Preferred configuration: The inner wall of the screening box is provided with stepped grooves, both ends of the screen plate are fixed with end plates, and the end plates are vertically slidably installed inside the stepped grooves. A spring is evenly provided between the bottom of the end plate and the stepped grooves. A coarse material outlet is provided on the lower part of one side of the screening box, and a fine material outlet is provided at the bottom of the screening box.

[0010] Preferably, the screen plate is inclined inside the screening box, with the coarse material inlet corresponding to the lower end of the screen plate and the fine material inlet corresponding to the bottom of the screen plate.

[0011] Preferably, the drive mechanism includes a mounting groove, a gear ring, gears, a drive motor, a worm, a worm wheel, and a protective shell. The mounting groove is located inside the conical base. The gear ring is horizontally rotatably mounted inside the mounting groove. Gears are uniformly meshed around the outer side of the gear ring in the circumferential direction. The drive motor is mounted at the bottom of the mounting groove. The output end of the drive motor is coaxially connected to the bottom of a set of gears. Worms are mounted on the top of each gear. Worm wheels are coaxially mounted on the ends of multiple sets of bottom conveyor rollers in the strip grooves. Multiple sets of worm wheels mesh with the worms respectively. Protective shells are provided on the outer side of both the worm and the worm wheel.

[0012] Preferred configuration: The hanging rods are set perpendicular to the outer wall of the conveyor belt, and the top of each hanging rod is provided with anti-slip texture. The spacing between two adjacent sets of hanging rods is 8-15cm.

[0013] Preferably, the inner top of the separator is conical, the gap between the inner side of the separator and the outer wall of the cone sleeve decreases from top to bottom, and the bottom of the separator is funnel-shaped.

[0014] Preferably, a support plate is fixed between the outer side of the bottom end of the conical base and the inner wall of the separation cylinder, and the support plate is perpendicular to the surface of the separation cylinder.

[0015] This invention also provides an intelligent and environmentally friendly method for treating construction waste, comprising the following steps: Step 1: The construction waste is injected into the separation cylinder through the feed hopper. The waste falls onto the surface of the conical guide block and spreads outward under the guidance of the conical guide block, flowing evenly through the outer wall of the conical sleeve. Step 2: Start the drive mechanism. The drive motor drives all the worms to rotate through the meshing of the gears and the ring gear. The worms, in conjunction with the worm wheel, drive the conveyor rollers to rotate, thereby driving the conveyor belt to convey upwards. Step 3: The conveyor belt drives the hanging rod to move upward. The hanging rod catches the lightweight waste materials such as plastic bags and cement bags flowing through the outer wall of the cone sleeve. During the conveying process, the slicing blade at the bottom of the cone guide block cuts the bag of lightweight waste materials, and the heavy impurities such as concrete debris and sand inside the bag fall off. Step 4: Heavy impurities fall onto the screen plate in the screening box. At the same time, the conical guide block shakes up and down under the impact of the waste material through the slide rod and spring 2, which drives the vertical rod to move up and down synchronously. The vertical rod and the screen plate vibrate up and down in the stepped groove through spring 1, which classifies and screens the heavy impurities. Fine material is discharged from the fine material outlet and coarse material is discharged from the coarse material outlet. Step 5: The conveyor belt drives the hanging rod to continue moving upward. When the hanging rod passes through the trough at the top of the discharge pipe, the light waste material falls into the discharge pipe under its own weight, the obstruction of the inner walls on both sides of the trough, and the downward pressure of the pressure block. When the vertical rod shakes up and down, the serrated blade on its bottom surface cuts the light waste material wrapped around the vertical rod to avoid blockage. Step 6: Lightweight waste is discharged through a discharge pipe, completing the intelligent and environmentally friendly treatment of construction waste.

[0016] The beneficial effects of this invention are as follows: This invention provides an intelligent and environmentally friendly treatment device and method for construction waste. By setting a conical guide block at the top of the separation cylinder, the construction waste is quickly diffused outward after being injected, ensuring that the waste flows evenly across the outer wall of the conical sleeve. In conjunction with the conveyor belt arranged circumferentially on the outer wall of the conical sleeve and the hanging rod set on the outside, the conveyor belt drives the hanging rod to move upward during the natural fall of the waste. It can accurately catch and transport lightweight packaging waste such as plastic bags and cement bags in the waste. Moreover, the conveying path can work in synergy with the slicing blade at the bottom of the conical guide block to efficiently cut the bag, so that the heavy impurities such as concrete debris and sand inside can be completely removed and discharged. Finally, when the hanging rod turns through the groove at the top of the discharge pipe, it can intercept the lightweight waste after the impurities are removed and make it fall into the discharge pipe for centralized discharge. This effectively reduces the amount of impurities remaining in the lightweight waste, eliminates the need for additional manual sorting, and significantly improves the recycling purity and cleaning effect of lightweight waste.

[0017] The bottom of the conical guide block is connected to the conical sleeve by a spring and a sliding rod, allowing the conical guide block to vibrate up and down when impacted by waste material. This, combined with the slicing blade, further enhances the tearing effect on the lightweight waste bag, ensuring more thorough removal of impurities. Simultaneously, the bottom end of the vertical rod, which is linked to the conical guide block, passes through the discharge pipe and connects to the screen plate. During the vibration of the conical guide block, it can synchronously drive the screen plate to vibrate, achieving graded screening of the detached heavy impurities and improving the functionality of the equipment. In addition, the pressure block set at the top of the vertical rod can press the lightweight waste material downwards during the up and down vibration, preventing the bag from accumulating at the top. The serrated blades arranged along the length of the bottom end can cut the lightweight waste material intercepted at the bottom of the vertical rod, effectively preventing blockage of the discharge pipe, ensuring continuous and stable operation of the equipment, and further improving the overall processing efficiency.

[0018] Through the coordinated operation of various components, the system achieves automated separation of lightweight packaging waste from internal impurities in construction waste, graded screening of heavy components, and anti-clogging protection during equipment operation. The entire process requires minimal manual intervention, which not only reduces labor intensity and cost but also significantly shortens the processing time. At the same time, the improved purity of lightweight waste and the graded recovery of heavy impurities increase the resource utilization rate of construction waste and reduce waste emissions. This not only meets environmental protection requirements but also achieves resource recycling, fully satisfying the treatment needs of construction waste. Attached Figure Description

[0021] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0022] like Figures 1-9 As shown, this embodiment provides an intelligent and environmentally friendly treatment device for construction waste, including a frame 1, a screening box 2, a separation cylinder 4, and a drive mechanism 11. The screening box 2 is fixed to the top of the frame 1, and the separation cylinder 4 is fixedly installed above the screening box 2 and communicates with the inside of the screening box 2. The top of the separation cylinder 4 is provided with a feed hopper 14, and a conical base 5 is fixedly installed at the bottom of the separation cylinder 4. A conical sleeve 6 is fixedly fitted on the top of the conical base 5. Several strip grooves 7 are provided on the outer wall of the conical sleeve 6 along the circumferential direction. Conveying rollers 8 are rotatably installed at both the upper and lower ends inside the strip grooves 7. A conveyor belt 9 is fitted on the outer side of the conveyor rollers 8, and several hanging rods 10 are fixed at intervals on the outer wall of the conveyor belt 9. A conical guide block 15 is movably provided at the top of the separator 4. Several slicing blades 16 are evenly fixed at the bottom of the conical guide block 15 along the circumference, and the bottom of the slicing blades 16 corresponds to the conveying path of the conveyor belt 9. The cone sleeve 6 has a discharge pipe 12 inside, which passes through the cone base 5 and extends to the outside of the separation cylinder 4. The top of the discharge pipe 12 has a through groove 13 that is compatible with the hanging rod 10. A vertical rod 17 is fixed at the bottom center of the conical guide block 15. The bottom end of the vertical rod 17 slides through the discharge pipe 12 and extends into the screening box 2 and is connected to the screen plate 3. The drive mechanism 11 is installed inside the conical base 5 and is connected to the conveyor roller 8 for transmission.

[0023] After construction waste is injected into the separation cylinder 4 through the feed hopper 14, it flows evenly over the outer wall of the cone sleeve 6 under the guidance of the cone guide block 15. The drive mechanism 11 provides power to drive the conveyor roller 8 to rotate, which in turn drives the conveyor belt 9 and the hanging rod 10 to move upward. The hanging rod 10 accurately catches and conveys the light waste. The slicing knife 16 at the bottom of the cone guide block 15 cuts through the bag body with its shaking action, causing the heavy impurities inside to fall off. The heavy impurities fall into the screening box 2, where the screen plate 3 driven by the vertical rod 17 vibrates and classifies the waste. Fine material is discharged from the fine material outlet 201, and coarse material is discharged from the coarse material outlet 202. Light waste falls into the pipe through the groove 13 at the top of the discharge pipe 12. The serrated knife 1702 on the vertical rod 17 cuts the entangled waste to prevent blockage. Finally, the light waste is discharged from the discharge pipe 12. The entire process realizes the automated separation, screening and environmental protection of construction waste.

[0024] In this embodiment, a slide rod 1502 is evenly provided between the bottom of the tapered guide block 15 and the top of the tapered sleeve 6. A second spring 1501 is sleeved on the outer side of the slide rod 1502, and the two ends of the second spring 1501 are fixedly connected to the tapered guide block 15 and the tapered sleeve 6 respectively. The slide rod 1502 is slidably connected to the tapered guide block 15 and fixedly connected to the tapered sleeve 6.

[0025] When construction waste falls onto the surface of the conical guide block 15, the conical structure of the conical guide block 15 evenly spreads the waste outward, guiding it to flow through the outer wall of the conical sleeve 6. The impact force of the waste causes the conical guide block 15 to slide up and down along the slide rod 1502. The spring 1501 on the outside of the slide rod 1502 stretches and deforms accordingly, generating an elastic restoring force, which drives the conical guide block 15 to continuously shake up and down. When the conical guide block 15 shakes, the slicing blade 16 at the bottom moves up and down synchronously, forming a relative motion with the lightweight waste conveyed on the conveyor belt 9, efficiently cutting through the bag. At the same time, the vertical rod 17 fixed at the center of the bottom of the conical guide block 15 moves up and down synchronously with the conical guide block 15, realizing the power linkage transmission.

[0026] In this embodiment, a pressure block 1701 is fixed at the top of the vertical rod 17, and a serrated blade 1702 is provided at the bottom of the vertical rod 17 along the length direction. The bottom of the discharge pipe 12 is provided with a through hole 1201 that cooperates with the vertical rod 17 and a groove 1202 that cooperates with the serrated blade 1702.

[0027] When the vertical rod 17 moves up and down with the conical guide block 15, the pressure block 1701 at the top moves up and down synchronously, exerting downward pressure on the light waste material at the top of the discharge pipe 12 to prevent the bag from accumulating at the top. The bottom end of the vertical rod 17 passes through the through hole 1201 of the discharge pipe 12, and the serrated blade 1702 on its bottom surface corresponds to the groove 1202 of the discharge pipe 12. When the light waste material accidentally gets tangled on the vertical rod 17, the serrated blade 1702 moves up and down with the vertical rod 17 and cuts the tangled waste material along the groove 1202, effectively preventing blockage inside the discharge pipe 12 and ensuring that the light waste material falls and is discharged smoothly.

[0028] In this embodiment, a stepped groove 203 is provided on the inner wall of the screening box 2, and end plates 205 are fixed at both ends of the screen plate 3. The end plates 205 are vertically slidably disposed inside the stepped groove 203. Springs 204 are evenly disposed between the bottom of the end plates 205 and the stepped groove 203. A coarse material inlet 202 is provided at the lower part of one side of the screening box 2, and a fine material inlet 201 is provided at the bottom of the screening box 2. The screen plate 3 is inclinedly disposed inside the screening box 2, with the coarse material inlet 202 corresponding to the lower end of the screen plate 3 and the fine material inlet 201 corresponding to the bottom of the screen plate 3.

[0029] The end plates 205 at both ends of the sieve plate 3 are embedded in the stepped grooves 203 on the inner wall of the screening box 2. The spring 204 between the bottom of the end plate 205 and the stepped groove 203 is in a natural extension and contraction state. When the vertical rod 17 moves up and down, it drives the sieve plate 3 to vibrate up and down synchronously. The spring 204 then repeatedly extends and contracts, increasing the vibration amplitude of the sieve plate 3. After heavy impurities fall onto the inclined sieve plate 3, under the action of vibration, fine materials with a particle size smaller than the sieve holes of the sieve plate 3 pass through the sieve holes and fall to the bottom of the screening box 2, and are discharged from the fine material outlet 201. Coarse materials with a particle size larger than the sieve holes of the sieve plate 3 slide down the inclined direction of the sieve plate 3 and are discharged from the coarse material outlet 202 corresponding to the lower end of the sieve plate 3, realizing the graded recovery of heavy impurities.

[0030] In this embodiment, the drive mechanism 11 includes a mounting groove 1101, a gear ring 1102, a gear 1103, a drive motor 1104, a worm 1105, a worm wheel 1106, and a protective shell 1107. The mounting groove 1101 is formed inside the conical base 5. The gear ring 1102 is horizontally rotatably mounted inside the mounting groove 1101. The gear 1103 is uniformly meshed around the outer side of the gear ring 1102 in the circumferential direction. The drive motor 1104 is mounted at the bottom of the mounting groove 1101. The output end of the drive motor 1104 is coaxially connected to the bottom of a set of gears 1103. The top of each gear 1103 is mounted with a worm 1105. The ends of the bottom conveying rollers 8 of multiple sets of strip grooves 7 are coaxially mounted with worm wheels 1106. The multiple sets of worm wheels 1106 mesh with the worm 1105 respectively. The outer sides of the worm 1105 and the worm wheel 1106 are provided with protective shells 1107.

[0031] After the drive motor 1104 starts, its output end drives the coaxially connected gear 1103 to rotate. The gear 1103 meshes with the gear ring 1102 in the mounting groove 1101. Through the circumferential rotation of the gear ring 1102, all gears 1103 meshing with the gear ring 1102 are driven to rotate synchronously. The worm 1105 at the top of each gear 1103 rotates together with the gear 1103. The worm 1105 meshes with the worm wheel 1106 at the end of the conveyor roller 8 at the bottom of the strip groove 7, transmitting power to the conveyor roller 8. When the conveyor roller 8 rotates, it drives the conveyor belt 9 to tilt upwards and stably convey along the outer wall of the cone sleeve 6 through friction with the conveyor belt 9. The protective shell 1107 protects the worm 1105 and the worm wheel 1106, preventing impurities from entering and affecting the transmission accuracy.

[0032] In this embodiment, the hanging rod 10 is set perpendicular to the outer wall of the conveyor belt 9, and the top of the hanging rod 10 is provided with anti-slip texture. The distance between two adjacent sets of hanging rods 10 is 8-15cm.

[0033] The hanging rod 10 is vertically fixed to the outer wall of the conveyor belt 9. The anti-slip texture at the top increases the friction with the lightweight waste. The 8-15cm spacing between adjacent hanging rods 10 ensures that the waste conveying path on the outer wall of the cone sleeve 6 is fully covered, accurately catching lightweight waste such as plastic bags and cement bags. The hanging rod 10 moves upward with the conveyor belt 9, conveying the lightweight waste from the outer wall of the cone sleeve 6 to the top of the discharge pipe 12. When the hanging rod 10 passes through the groove 13 at the top of the discharge pipe 12, the lightweight waste loses the support of the hanging rod 10 and, under its own weight, the obstruction of the inner walls on both sides of the groove 13, and the downward pressure of the pressure block 1701, falls smoothly into the discharge pipe 12, realizing the separation of the lightweight waste from the hanging rod 10.

[0034] In this embodiment, the inner top of the separation cylinder 4 is conical, the gap between the inner side of the separation cylinder 4 and the outer wall of the cone sleeve 6 decreases from top to bottom, and the bottom end of the separation cylinder 4 is funnel-shaped.

[0035] The top of the separator cylinder 4 is conical, and the gap between it and the outer wall of the cone sleeve 6 decreases from top to bottom. This structure can guide the waste to converge towards the outer wall of the cone sleeve 6, ensuring that the waste is in full contact with the hanging rod 10 on the conveyor belt 9. The bottom of the separator cylinder 4 is funnel-shaped, which can concentrate and guide the heavy impurities that fall off after the bag is broken into the screening box 2, avoiding the heavy impurities from remaining in the separator cylinder 4.

[0036] In this embodiment, a support plate is fixed between the outer side of the bottom end of the conical base 5 and the inner wall of the separation cylinder 4, and the support plate is perpendicular to the surface of the separation cylinder 4.

[0037] The support plate between the outer bottom of the conical base 5 and the inner wall of the separation cylinder 4 is perpendicular to the surface of the separation cylinder 4, providing stable support for the conical base 5, enhancing the connection strength between the conical base 5 and the separation cylinder 4, and preventing the structure from loosening due to vibration during equipment operation.

[0038] like Figures 1-9 As shown in the figure, this embodiment provides a method for intelligent and environmentally friendly treatment of construction waste. The process is as follows: Step 1: The construction waste is injected into the separation cylinder 4 through the feed hopper 14. The waste falls onto the surface of the conical guide block 15 and diffuses outward under the guidance of the conical guide block 15, flowing evenly through the outer wall of the conical sleeve 6. Step 2: Start the drive mechanism 11. The drive motor 1104 drives all the worms 1105 to rotate through the meshing of the gear 1103 and the gear ring 1102. The worms 1105, in conjunction with the worm wheel 1106, drive the conveyor roller 8 to rotate, thereby driving the conveyor belt 9 to convey upward. Step 3: The conveyor belt 9 drives the hanging rod 10 to move upward. The hanging rod 10 catches the lightweight waste materials such as plastic bags and cement bags flowing through the outer wall of the cone sleeve 6. During the conveying process, the slicing knife 16 at the bottom of the cone guide block 15 cuts the bag of lightweight waste materials, and the heavy impurities such as concrete debris and sand inside the bag fall off. Step 4: Heavy impurities fall onto the screen plate 3 inside the screening box 2. At the same time, the conical guide block 15 vibrates up and down under the impact of the waste material through the slide rod 1502 and the second spring 1501, which drives the vertical rod 17 to move up and down synchronously. The vertical rod 17, together with the screen plate 3, vibrates up and down in the stepped groove 203 through the first spring 204, classifying and screening the heavy impurities. Fine material is discharged from the fine material outlet 201, and coarse material is discharged from the coarse material outlet 202. Step 5: The conveyor belt 9 drives the hanging rod 10 to continue moving upward. When the hanging rod 10 passes through the groove 13 at the top of the discharge pipe 12, the light waste material falls into the discharge pipe 12 under its own weight, the obstruction of the inner walls on both sides of the groove 13 and the downward pressure of the pressure block 1701. When the vertical rod 17 shakes up and down, the serrated blade 1702 on its bottom surface cuts the light waste material wrapped around the vertical rod 17 to avoid blockage. Step 6: Lightweight waste is discharged through discharge pipe 12, completing the intelligent and environmentally friendly treatment of construction waste.

[0039] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
