Description

Technical Field

[0001] This invention relates to a device for recycling and reusing building material waste, belonging to the field of building material technology. Background Technology

[0002] With the continuous development of the social economy and the accelerating pace of urban construction, the number of various construction projects has exploded. During this process, a large amount of construction waste is generated due to factors such as manual demolition, natural wear and tear, and project renovation, with waste bricks and stones making up a particularly prominent proportion. Waste bricks and stones themselves have high recycling value. Based on the concept of resource recycling, construction waste recycling and reuse technologies have been gradually promoted and applied, realizing the circular use of building materials. This not only aligns with the development concept of energy recycling in the new era but also effectively protects the ecological environment.

[0003] Currently, the recycling and reuse of waste bricks and stones is mainly accomplished through recycling equipment. This equipment typically consists of a crushing module, a conveying module, and a screening module. The conveying module is connected to the discharge port of the crushing module, while the screening module is connected to the discharge port of the conveying module. The specific operating process is as follows: First, waste bricks and stones are fed into the crushing module. After crushing, the crushed material enters the conveying module and is then transported to the screening module. The screening module then grades and screens the material. The qualified material can be used as raw material for the production of flooring and other products, thus realizing the transformation of construction waste into usable resources.

[0004] Given the large size and hard texture of waste bricks and stones, impact crushers are typically used in the crushing module to ensure crushing efficiency. However, waste bricks and stones often have concrete and other auxiliary materials adhering to their surface, which easily produces large, flaky pieces during impact crushing. These pieces can easily be discharged directly from the gaps between the impact points in the equipment. Upon entering the subsequent screening module, these flaky pieces are screened out, significantly increasing the risk of clogging in the screening module. Furthermore, they need to be cleaned and returned to the crushing module for further processing, leading to reduced overall operational efficiency and consequently affecting the effectiveness and quality of construction waste recycling.

[0018] 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.

[0019] Example 1: As Figures 1-9 As shown, a device for recycling and reusing construction waste is provided, comprising: a rectangular frame 1, with the upper end of the frame 1 recessed downward to form an opening 12, and the opening 12 extending to the top of the inside of the frame 1, through which a rectangular shell 2 and a discharge cylinder 11 are connected and arranged. The discharge cylinder 11 is installed on the top of the inside of the frame 1, and the upper end of the discharge cylinder 11 is connected to the lower end of the opening 12, through which materials are discharged outward. The rectangular shell 2 is installed on the upper end of the frame 1, and the upper end of the opening 12 is connected to the lower end of the rectangular shell 2, through which the rectangular shell 2 provides installation space for components such as rollers 9. The outer shell 4 is connected and installed on the upper end of the rectangular shell 2, through which the outer shell 4 provides installation space for components such as fixing plates 73. The feed cylinder 5 is connected and installed on the upper left end of the outer shell 4, and the feed cylinder 5 is arranged with the left side higher than the right side, through which construction waste is fed into the outer shell 4. The roller 9, extending into the outer shell 4, is rotatably connected to the inside of the rectangular shell 2. The roller 9 provides a mounting carrier for the hammer 91. Multiple hammers 91 are equidistantly installed at the annular end of the roller 9, and the cross-section of the hammer 91 is a trapezoid with a narrow outer edge and a wide inner edge. The hammer 91 provides a mounting carrier for the auxiliary blade 92 and hammers construction waste such as bricks. The filter screen 8 located below the hammer 91 is installed inside the rectangular shell 2, and the cross-section of the filter screen 8 is arc-shaped. The crushed construction waste is filtered through the filter screen 8. Two guide plates 82 located below the mounting plate 7 are respectively set on the left and right ends of the filter screen 8. The two guide plates 82 are arranged in a V-shape with a wider upper edge and a narrower lower edge, and the outward ends of the two guide plates 82 are connected to the left and right walls inside the rectangular shell 2. The two guide plates 82 work together to guide the crushed construction waste into the filter screen 8. Multiple auxiliary blades 92 are equidistantly arranged at the outward ends of multiple hammers 91, and the cross-section of the auxiliary blades 92 is triangular. The lower end of the lowest auxiliary blade 92 is in contact with the upper end of the filter screen 8. Multiple cutting blade groups arranged in an arc structure are equidistantly installed on the upper end of the filter screen 8. Each cutting blade group includes multiple crushing blades 81 fixed on the upper end of the filter screen 8. The crushing blades 81 located on the lower side of the hammers 91 and the auxiliary blades 92 are arranged alternately. The crushing blades 81 and the auxiliary blades 92 work together to crush the sheet-like construction waste. The fixed part of the drive device located on the right side of the rectangular shell 2 is installed on the upper end of the frame 1. The drive device drives the small pulley 31 to rotate. The drive device can be a motor 3. The front end of the shaft of the roller 9 extends out of the front side of the rectangular shell 2, and the large pulley 32 is installed on the front end of the shaft of the roller 9. The large pulley 32 drives the roller 9 to rotate. The small pulley 31 is then set on the front end of the output shaft of the drive device. The large pulley 32 and the small pulley 31 are connected by a belt. The small pulley 31 works with the belt to make the large pulley 32 rotate. The mounting plate 7 located on the right side of the rotating blade 61 is placed inside the housing 4, and the cross-section of the mounting plate 7 is arc-shaped. The mounting plate 7 provides a mounting carrier for components such as the fixing plate 73. Multiple fixing plates 73 are installed at equal intervals on the right end of the mounting plate 7, and the right ends of the multiple fixing plates 73 are connected to the inner right wall of the housing 4. The multiple fixing plates 73 work together to increase the installation stability of the mounting plate 7. Then, multiple rectangular rods 72 penetrating the mounting plate 7 are evenly slidably connected to the left end of the mounting plate 7. The rectangular rods 72 provide a mounting carrier for the circular plate 71. Multiple circular plates 71 located outside the fixed plate 73 are respectively installed on the right ends of multiple rectangular rods 72. The circular plates 71 restrict the installation of elastic elements 76. Multiple elastic elements 76 located outside the rectangular rods 72 are respectively installed on the left ends of multiple circular plates 71, and the left ends of multiple elastic elements 76 are all connected to the right end of the mounting plate 7. The elastic elements 76 provide rebound force for the impact operation. The elastic elements 76 can be springs. Multiple impact plates 74 are respectively installed on the left ends of multiple rectangular rods 72. The impact plates 74 provide a mounting carrier for the crushing cone head 75 and can crush the construction waste by impact. Multiple crushing cone heads 75 are installed on the left ends of multiple impact plates 74. The crushing cone heads 75 are located to the right of the auxiliary blade 92 and the right of the rotating blade 61. The crushing cone heads 75 are arranged with the left side narrower and the right side wider. The crushing cone heads 75 assist in crushing the construction waste.

[0020] In use, the motor 3 is started first, which drives the small pulley 31 to rotate. With the assistance of the belt, the large pulley 32 rotates, which in turn rotates the roller 9, causing multiple hammers 91 to rotate synchronously, which in turn causes multiple auxiliary blades 92 to rotate synchronously. Then, construction waste such as bricks and stones is put into the feeding cylinder 5. Because the feeding cylinder 5 is tilted, the construction waste in the feeding cylinder 5 will slide down to the right along the feeding cylinder 5, and then the construction waste enters the outer shell 4 and falls onto the roller 9. At this time, the roller 9 and multiple hammers 91 are rotating, so the falling construction waste will collide with the hammers 91, and the collided construction waste will fly to the right. The flying construction waste will collide with the corresponding local area in the counterattack structure formed by multiple counterattack plates 74, so that the corresponding number of counterattack plates 74 move to the right, thereby causing the corresponding rectangular rod 72 to move to the right, thereby causing the circular plate 71 to move to the right, thereby stretching the corresponding elastic element 76, thereby causing the elastic element 76 to generate elastic force. Under the elastic force of the elastic element 76, the circular plate 71, the rectangular rod 72 and the counter-attack plate 74 move to the left, thereby applying an effective thrust to the construction waste in contact with the counter-attack plate 74. Under the action of the thrust, the impacting construction waste will move to the left, and then the construction waste will collide with the rotating hammer 91, thereby repeatedly impacting the construction waste between the hammer 91 and the counter-attack plate 74, and thus crushing the construction waste. When construction waste collides with the corresponding counter-reinforcement plates at the corresponding locations and in the corresponding quantities, the corresponding crushing cone 75 will perform point-breaking crushing of the construction waste, thereby applying effective thrust and crushing operation to the construction waste. This effectively reduces the probability of incomplete crushing of the splashed construction waste due to factors such as the small impact area, effectively reduces the probability of deformation of subsequent components such as the crushing blade 81, and effectively ensures the recycling effect and quality of construction waste.

[0021] The crushed construction waste will fall onto the filter screen 8. At this time, the qualified construction waste will pass through the filter screen 8 and fall down, while the flaky construction waste will remain on the filter screen 8. However, the qualified construction waste will pass through the opening 12 and enter the discharge cylinder 11. Then, the qualified construction waste will be discharged through the discharge cylinder 11, thereby completing the effective reuse of the recycled construction waste. Simultaneously, the rotating hammer 91 causes multiple auxiliary blades 92 to rotate, thus causing the multiple auxiliary blades 92 to rotate on the upper end of the filter screen 8. Since the auxiliary blades 92 and the crushing blades 81 are arranged alternately, the rotating auxiliary blades 92 will move relative to the crushing blades 81. The relative movement of the auxiliary blades 92 and the crushing blades 81 will further crush the remaining construction waste, realizing the combination of crushing and screening of construction waste, and timely crushing of the remaining construction waste after filtration. This effectively avoids the need for further crushing of the crushed construction waste, effectively reduces the probability of blockage, improves work efficiency, and effectively ensures the recycling effect and quality of construction waste.

[0022] Example 2: Figure 2 , Figure 3 and Figure 5 As shown, the rotating shaft 6 is rotatably connected inside the housing 4, and the rear end of the rotating shaft 6 extends out of the rear side of the housing 4. The rotating shaft 6 provides a mounting carrier for components such as the rotating blade 61, and multiple rotating blades 61 located on the upper side of the auxiliary blade 92 are equidistantly mounted on the annular end of the rotating shaft 6. The left end of the rotating blade 61 extends into the feed cylinder 5. Multiple rotating blades 61 work together to cut construction waste into blocks. The auxiliary shaft 37 is rotatably connected to the rear end of the housing 4. The auxiliary shaft 37 provides a mounting carrier for components such as the second sprocket 35. The second gear 36 is set on the annular end of the auxiliary shaft 37. The first gear 34 is then installed on the rear end of the rotating shaft 6, and the upper end of the first gear 34 meshes with the second gear 36. The first gear 34 and the second gear 36 work together to make the rotating shaft 6 rotate. The rear end of the shaft of roller 9 extends out of the rear side of rectangular shell 2, and the first sprocket 33 is set on the rear end of the shaft of roller 9. The second sprocket 35 is installed on the rear end of auxiliary shaft 37, and the first sprocket 33 and the second sprocket 35 are connected by a chain. The first sprocket 33, the second sprocket 35 and the chain work together to make roller 9 and auxiliary shaft 37 rotate synchronously. A vertically arranged rubber sheet 51 is placed at the top of the inside of the feed cylinder 5. The rubber sheet 51 serves two purposes: firstly, it provides an installation carrier for the load-bearing strips 53, and secondly, it seals the opening of the feed cylinder 5. Multiple through grooves 52 are formed by a rightward indentation on the left end of the rubber sheet 51, and the through grooves 52 extend to the lower end of the rubber sheet 51. The multiple through grooves 52 work together to facilitate the passage of construction waste through the rubber sheet 51. Multiple load-bearing strips 53 are equidistantly arranged on the lower end of the rubber sheet 51, and the load-bearing strips 53 and through grooves 52 are arranged alternately. The multiple load-bearing strips 53 work together to return the rubber sheet 51 to its original position.

[0023] In operation, the motor 3, small pulley 31, belt, and large pulley 32 are used to rotate the roller 9 and multiple hammers 91, thereby rotating the first sprocket 33. With the assistance of the chain, the second sprocket 35 rotates, which in turn rotates the auxiliary shaft 37, causing the second gear 36 to rotate. Since the second gear 36 meshes with the first gear 34, the rotation of the second gear 36 will cause the first gear 34 to rotate, which in turn will cause the rotating shaft 6 to rotate, thereby causing multiple rotating blades 61 to rotate synchronously. This achieves linkage between crushing and cutting operations, effectively reducing equipment costs. Then, construction waste such as bricks and stones is put into the feeding cylinder 5. Because the feeding cylinder 5 is tilted, the construction waste in the feeding cylinder 5 will slide down to the right along the feeding cylinder 5. Then the sliding construction waste will come into contact with the rubber sheet 51 and lift the rubber sheet 51, so that the construction waste will continue to slide to the right along the feeding cylinder 5. After the construction waste is separated from the rubber sheet 51, the weight of the load-bearing strip 53 causes the rubber sheet 51 to return to its original position, thereby sealing the feed cylinder 5. This effectively reduces the probability of dust floating out of the feed cylinder 5 opening when the construction waste is subsequently broken down, thus reducing the probability of pollution to the working environment and ensuring the recycling effect and environmental protection effect of construction waste. The sliding construction waste enters the outer shell 4 from the feed cylinder 5, and then comes into contact with the rotating blade 61. At this time, the rotating blade 61 is in a rotating state, and multiple rotating blades 61 will cut the construction waste, thereby cutting the construction waste into blocks. This pre-processing of construction waste into blocks effectively reduces the probability of material jamming at the crushing position between the roller 9 and the impact plate 74 due to factors such as the large volume of the construction waste. It also effectively reduces the probability of deformation of the auxiliary blade 92, effectively ensuring the recycling effect and quality of construction waste.

[0024] Then, small pieces of construction waste will collide with the rotating hammer 91, causing the construction waste to fly to the right and collide with the counter-attack plate 74, rectangular rod 72 and second elastic components, so that the construction waste will repeatedly collide with the rotating hammer 91, thereby crushing the construction waste. Then, the shredded construction waste is screened using the filter screen 8, and the remaining construction waste is crushed in time using the rotating auxiliary blade 92 and the crushing blade 81. At the same time, the qualified construction waste is discharged through the opening 12 and the discharge cylinder 11, thus completing the effective reuse of the recycled construction waste.

[0025] Example 3: Figure 10 As shown, a V-shaped baffle 56 is attached to the bottom of the inside of the feed cylinder 5, and the V-shaped baffle 56 is arranged with a wider top and a narrower bottom. Two elastic cloths 55 are symmetrically installed on the upper end of the V-shaped baffle 56, and the upper ends of the two elastic cloths 55 are connected to the top of the inside of the feed cylinder 5. The two elastic cloths 55 and the V-shaped baffle 56 are used together to seal the opening of the feed cylinder 5. Multiple round rods 54 are equidistantly arranged on the bottom inner end of the V-shaped baffle 56, and the upper ends of the multiple round rods 54 extend out of the upper side of the feed cylinder 5. The round rods 54 are slidably connected to the feed cylinder 5. The multiple round rods 54 work together to guide the movement of the V-shaped baffle 56.

[0026] In use, the motor 3, small pulley 31, belt and large pulley 32 are used to make the roller 9 and multiple hammers 91 rotate. At the same time, the first sprocket 33, chain, second sprocket 35 and auxiliary shaft 37 and other components make the rotating shaft 6 and multiple rotating blades 61 rotate with the roller 9. Then, construction waste such as bricks and stones is put into the feeding cylinder 5. Because the feeding cylinder 5 is tilted, the construction waste in the feeding cylinder 5 will slide down to the right along the feeding cylinder 5. Then, the sliding construction waste first contacts the left-facing inclined surface of the V-shaped baffle 56. The construction waste will exert a pushing force on the inclined surface of the V-shaped baffle 56, thereby causing the V-shaped baffle 56 and the round rod 54 to move upward, so that the construction waste passes through the space below the V-shaped baffle 56 and continues to slide to the right along the feeding cylinder 5. After the construction waste is separated from the V-shaped baffle 56, the weight of the V-shaped baffle 56 causes it to move down and return to its original position. This allows the V-shaped baffle 56 and the elastic cloth 55 to seal the feed cylinder 5, effectively reducing the probability of dust floating out of the feed cylinder 5 opening during subsequent construction waste disposal. This also reduces the probability of pollution to the working environment and ensures effective construction waste recycling and environmental protection.
