Description

TECHNICAL FIELD

[0002] The construction waste recycling equipment is an equipment for crushing, sorting and recycling mixed waste such as concrete blocks, bricks, scrap metal and plastics generated in the process of demolition, decoration and the like.

[0003] The current construction waste recycling equipment, when in use, is complex in composition, often mixed with light plastic waste such as plastic and foam, and metal scraps. These impurities are still easy to entangle and wrap each other after crushing, which makes it difficult to completely separate in the sorting process.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.​​​​

[0023] To address the technical problem of lightweight plastic waste such as plastic bags and foam being difficult to separate and recycle, resulting in poor recycling efficiency of useful waste, such as... Figures 1-10 As shown, the following preferred technical solutions are provided: A construction waste recycling device includes a support frame 1, which can support and fix various components. A controller is installed on one side of the support frame 1 for convenient control of various electrical devices. The controller is existing technology and is not shown in the figure. A cylinder 2 is set inside the support frame 1. A crushing component 3 is connected to the top of the cylinder 2. After the construction waste passes through the impurity removal grid to intercept larger hard impurities, it enters the external jaw crusher for pre-crushing. Then, a magnetic separator adsorbs some magnetic metals. Subsequently, the construction waste is finely crushed by the crushing component 3 and falls into the cylinder 2, which facilitates subsequent separation and recycling. The jaw crusher and the impurity removal grid are existing technologies and are not shown in the figure. A feeding component 4 is set inside the cylinder 2. Two impact components 5 are set inside the feeding component 4. A centrifugal throwing component 6 is set inside the cylinder 2. An air blowing component 7 is set on the bottom outer wall of the centrifugal throwing component 6. A first collection component 8 is set on the top outer wall of the cylinder 2. An air suction component 9 is set on one side of the first collection component 8.

[0024] In operation, the controller causes the crushing component 3 to finely crush the pre-treated construction waste, which then falls into the feeding component 4. The centrifugal throwing component 6 slowly accumulates downward force until it releases, at which point it rotates rapidly and simultaneously pushes upward. At the same time, the controller causes the feeding component 4 to rotate, causing the construction waste inside to gradually fall and collide with the high-speed rotating and resetting centrifugal throwing component 6. This facilitates the use of centrifugal force to violently impact and throw the falling construction waste against the high-speed moving centrifugal throwing component 6, ensuring the material is fully dispersed and expanded within the cylinder 2. Compared to existing technologies, this avoids the separation dead zones caused by materials obstructing or entangled during the separation process, thus improving the separation and recycling effect of useful waste. It also facilitates the breaking up of agglomerated and entangled impurities, preventing incomplete separation and recycling. During the movement of the feeding component 4, it sequentially drives two impactors... The impact component 5 circulates air intake, compression, and exhaust, generating a high-pressure airflow that impacts the falling construction waste, facilitating an increase in the falling speed of the construction waste. This, in turn, increases the impact force generated when the construction waste collides with the centrifugal throwing component 6, more efficiently breaking up the agglomeration of construction waste and thoroughly dispersing previously stuck and wrapped impurities. At the same time, it further increases the spread range of materials within the cylinder 2, reducing sorting dead zones caused by material obstruction, and improving the efficiency and thoroughness of useful waste separation and recycling. Simultaneously, the controller causes the blowing component 7 to blow towards the thrown construction waste, blowing lighter plastic waste such as plastic and foam towards the top of the cylinder 2. The suction component 9 creates negative pressure in the first collection component 8 to collect the lighter plastic waste such as plastic and foam. The remaining heavier metal fragments and construction waste fall due to gravity. An adsorption component 10 is installed inside the cylinder 2, and a second collection component 20 is installed on one side of the adsorption component 10.

[0025] During use, heavier metal fragments and construction waste, falling under gravity, will impact the adsorption component 10, causing the construction waste to be dispersed again. This prevents the construction waste from blocking each other and affecting the separation and recycling of lighter plastic waste such as plastic and foam, thereby further improving the recycling effect of useful waste. The controller energizes the adsorption component 10, generating magnetic adsorption to attract the falling metal fragments. The remaining construction waste is discharged through the discharge port at the bottom of the cylinder 2. When the adsorption component 10 needs to be cleaned, the controller causes the second collection component 20 to slide the adsorption component 10 out of the cylinder 2. Then, the controller cancels the energization of the adsorption component 10, causing the metal fragments to fall and be collected. After cleaning, the controller resets the second collection component 20 and the adsorption component 10 for subsequent adsorption operations.

[0026] like Figures 1-4 and Figure 6As shown, the crushing assembly 3 includes a crushing box 31 connected to the top of the cylinder 2. A first motor 32 is installed on one side of the crushing box 31. Two first rotating shafts 33 are rotatably connected inside the crushing box 31. The first rotating shafts 33 are fixedly connected to the output end of the first motor 32. Crushing rollers 34 are fixedly connected to the outer walls of the two first rotating shafts 33. A first gear 35 is fixedly connected to one end of the two first rotating shafts 33. The two first gears 35 mesh with each other.

[0027] like Figures 4-5 and Figure 7 As shown, the feeding assembly 4 includes a feeding hopper 41 fixedly connected to the inner wall of the cylinder 2, a support frame 42 fixedly connected to the bottom inner wall of the crushing box 31, a dual-shaft motor 43 fixedly connected inside the support frame 42, a second rotating shaft 44 fixedly connected to the output end of the dual-shaft motor 43, the second rotating shaft 44 being rotatably connected to the support frame 42, and a spiral blade 45 fixedly connected to the outer wall of the second rotating shaft 44. The diameter of the spiral blade 45 matches the diameter of the feeding port of the feeding hopper 41, preventing construction waste from falling when the spiral blade 45 is not rotating. Impact assembly 5 includes a third rotating shaft 51 fixedly connected to another output shaft of the dual-shaft motor 43. An eccentric wheel 52 is fixedly connected to the outer wall of the third rotating shaft 51. A limit groove 53 is formed on one side of the eccentric wheel 52. A rolling shaft 54 ​​is rotatably connected in the limit groove 53. A push-pull rod 55 is rotatably connected to the outer wall of the rolling shaft 54. A piston 56 is fixedly connected to one end of the push-pull rod 55. Air storage boxes 57 are fixedly connected to both sides of the crushing box 31. The piston 56 is slidably connected to the inner wall of the air storage box 57. A one-way valve 58 and an air outlet pipe 59 are respectively connected to one side of the air storage box 57. One end of the vent pipe 59 is connected to a pressure relief valve 510, and the other end of the pressure relief valve 510 is connected to a branch pipe 511. Both the vent pipe 59 and the branch pipe 511 are fixedly connected inside the hopper 41. A protective shell 512 is fixedly connected to the outer wall of the hopper 41. The branch pipe 511 is set at an angle downward, which can facilitate the spraying of high-pressure airflow toward the construction waste falling into the hopper 41. This not only helps to accelerate the falling speed of the construction waste to enhance its impact force when it collides with the centrifugal throwing component 6, but also breaks up materials that may stick together again during the falling process, preventing impurities from being wrapped around the waste.

[0028] like Figure 4 , Figure 8 and Figure 10As shown, the centrifugal spraying assembly 6 includes several support pipes 61 fixedly connected to the inner wall of the cylinder 2. One end of each support pipe 61 is fixedly connected to a support frame 62, and the bottom of the support frame 62 is fixedly connected to a fixing shell 63. A second motor 64 is installed on one side of the support frame 62, and the fixing shell 63 covers one side of the second motor 64. A rotating drum 65 is fixedly connected to the output end of the second motor 64. The rotating drum 65 is rotatably connected to the support frame 62. A first spring 66 is fixedly connected inside the rotating drum 65, and the other end of the first spring 66 is fixedly connected to a sliding rod 67. The sliding rod 67 is slidably connected to the support frame 62, and two limiting positions are fixedly connected to the outer wall of the sliding rod 67. Rod 68, limiting rod 68 and sliding rod 67 are slidably connected. One end of limiting rod 68 is rotatably connected to limiting shaft 69. Two limiting inclined plates 610 are fixedly connected to the inner wall of bearing frame 62. A throwing bowl 611 is fixedly connected to the top of sliding rod 67. Several arc-shaped baffles 612 are fixedly connected inside the throwing bowl 611. The arc-shaped baffles 612 facilitate the guidance and secondary impact of the falling construction waste when the throwing bowl 611 rotates at high speed. This allows the construction waste to be evenly thrown to different areas inside cylinder 2 along the arc surface, avoiding uneven dispersion caused by concentrated accumulation of materials. It also further breaks up the still sticky construction waste through impact.

[0029] like Figures 1-2 , Figure 4 and Figure 8 As shown, the air blowing assembly 7 includes a first mounting plate 71 fixedly connected to the outer wall of the cylinder 2. A high-pressure blower 72 is mounted on one side of the first mounting plate 71. A first round pipe 73 is fixedly connected to the outer wall of the cylinder 2. The air outlet of the high-pressure blower 72 is connected to the first round pipe 73. Several air outlet pipes 74 are connected to the top of the support pipe 61. A first filter screen 75 is fixedly connected to one end of the air outlet pipe 74.

[0030] like Figure 1 and Figure 4 As shown, the first collection component 8 includes a first collection frame 81 fixedly connected to the cylinder 2. A door panel is provided on one side of the first collection frame 81 to facilitate material unloading. The door panel is existing technology and is not shown in the figure. A second filter screen 82 is fixedly connected inside the first collection frame 81. The second filter screen 82 can facilitate filtration and prevent lightweight plastic waste such as plastic and foam from being mixed with a lot of dust particles.

[0031] like Figures 1-2 and Figure 4 As shown, the suction assembly 9 includes a second mounting plate 91 fixedly connected to the outer wall of the first collection frame 81. A suction fan 92 is installed on one side of the second mounting plate 91. The suction port of the suction fan 92 is connected to a second round pipe 93. The second round pipe 93 is fixedly connected to the first collection frame 81. Several suction pipes 94 are evenly connected to the second round pipe 93. A third filter screen 95 is fixedly connected to one end of the suction pipe 94.

[0032] In operation, the controller causes the first motor 32 to drive the first rotating shaft 33 to rotate. Through the meshing of two first gears 35, the other first rotating shaft 33 rotates, thereby driving the two crushing rollers 34 to finely crush the pre-treated construction waste. The waste then falls into the hopper 41. At this time, the second motor 64 drives the rotating drum 65 to rotate, causing the limiting shaft 69 to engage with the inclined surface of the limiting inclined plate 610. The limiting inclined plate 610 limits the movement of the sliding rod 67, which compresses the first spring 66 to store force until the limiting shaft 69 reaches the top of the inclined surface of the limiting inclined plate 610. At this point, the first spring 66 is released, and the controller causes the second motor 64 to rotate rapidly at a certain angle, causing the throwing bowl 611 to rotate rapidly, thus lifting the throwing bowl 611. The initial rotation speed of 1 ensures sufficient centrifugal force. Simultaneously, the release of the first spring 66 drives the slide bar 67 and the throwing bowl 611 to rise upwards. At the same time, the controller causes the dual-shaft motor 43 to drive the second rotating shaft 44 and the spiral blade 45 to rotate, causing the construction waste inside the hopper 41 to gradually fall and collide with the high-speed rotating and reset throwing bowl 611. This facilitates the use of centrifugal force to cause the falling construction waste to violently collide with and be thrown out by the high-speed centrifugal throwing component 6, allowing the material to be fully dispersed and spread within the cylinder 2. Compared with existing technologies, this can avoid the sorting dead corners caused by materials blocking and wrapping each other during the separation process, thereby improving the separation and recycling effect of useful waste. It also facilitates the breaking up of agglomerated and mutually wrapped impurities, avoiding incomplete separation and recycling.

[0033] During the operation of the dual-shaft motor 43, the third rotating shaft 51 and the eccentric wheel 52 are driven to rotate, thereby sequentially driving the two push-pull rods 55 and the piston 56 to alternately cycle and operate in the air storage box 57. During air intake, the push-pull rods 55 and the piston 56 draw outside gas into the air storage box 57 through the one-way valve 58. During exhaust, the push-pull rods 55 and the piston 56 compress the gas in the air storage box 57, causing the high-pressure gas inside to be discharged through the exhaust pipe 59, the pressure relief valve 510, and the branch pipe 511. This high-pressure airflow impacts the falling construction waste, facilitating an increase in the falling speed of the construction waste and thus increasing the impact force generated when the construction waste collides with the throwing bowl 611, enabling more efficient crushing. The system breaks up the agglomeration of construction waste, completely dispersing the originally sticky and wrapped impurities. At the same time, it further increases the spread of materials within the cylinder 2, reduces sorting dead zones caused by material obstruction, and improves the efficiency and thoroughness of useful waste separation and recycling. Simultaneously, the controller causes the high-pressure gas generated by the high-pressure blower 72 to be blown towards the thrown construction waste through the first circular pipe 73, support pipe 61, and air outlet pipe 74. Lighter plastic waste such as plastic and foam is blown towards the top of the cylinder 2. Through the cooperation of the suction fan 92, the second circular pipe 93, and the suction pipe 94, negative pressure is generated in the first collection frame 81, collecting the lighter plastic waste such as plastic and foam into the first collection frame 81. The remaining heavier metal fragments and construction waste fall due to gravity.

[0034] To address the technical problem of metal debris not being easily adsorbed and recycled, such as Figure 2 and Figure 9 As shown, the following preferred technical solutions are provided: like Figure 9 As shown, the adsorption assembly 10 includes a connecting frame 101 fixedly connected to the outer wall of the cylinder 2. Several electromagnetic rods 102 are slidably connected inside the connecting frame 101. A positioning block 104 is fixedly connected to one end of each electromagnetic rod 102. A positioning shaft 105 is rotatably connected inside the positioning block 104. A second spring 103 is fixedly connected to one side of the positioning block 104, and the other end of the second spring 103 is fixedly connected to the outer wall of the connecting frame 101.

[0035] like Figure 2 and Figure 9As shown, the second collection assembly 20 includes a second collection frame 201 threadedly connected to the bottom of the connecting frame 101. The second collection frame 201 is attached to the outer wall of the cylinder 2. An installation frame 202 is fixedly connected to the outer wall of the cylinder 2. A third motor 203 is installed on the top of the installation frame 202. A fourth rotating shaft 204 is fixedly connected to the output end of the third motor 203. The fourth rotating shaft 204 is rotatably connected to the installation frame 202. A second gear 205 is fixedly connected to the outer wall of the fourth rotating shaft 204. A gear ring 206 is rotatably connected to the outer wall of the cylinder 2. The second gear 205 meshes with the gear ring 206. A rotating ring 207 is fixedly connected to the bottom of the gear ring 206. The rotating ring 207 is rotatably connected to the outer wall of the cylinder 2. Several arc-shaped plates 208 are fixedly connected to the outer wall of the rotating ring 207.

[0036] During operation, heavier metal fragments and construction waste, falling under gravity, collide with the electromagnetic rod 102, further dispersing the construction waste and preventing it from obstructing each other, which would hinder the separation and recycling of lighter plastic and foam waste. This further improves the recycling efficiency of useful waste. The controller energizes the electromagnetic rod 102, generating magnetism to attract the falling metal fragments. The remaining construction waste is discharged through the discharge port at the bottom of the cylinder 2. When the electromagnetic rod 102 needs cleaning, the controller activates the third motor 203, which drives the fourth shaft 204 and the second gear 205 to rotate. The second gear 205 then... The gear ring 206 engages, driving the rotating ring 207 and the arc plate 208 to rotate. The arc plate 208 presses the positioning shaft 105, causing the positioning shaft 105 and the positioning block 104 to move, so that the electromagnetic rod 102 slides out from the cylinder 2 and enters the connecting frame 101. At the same time, the second spring 103 is stretched. During the movement, the connecting frame 101 pushes the metal debris adsorbed on the surface of the electromagnetic rod 102 to one place. Then, the controller cancels the power supply to the electromagnetic rod 102, so that the metal debris falls into the second collection frame 201 for easy collection. After cleaning, the controller resets the second collection component 20 and the adsorption component 10 for subsequent adsorption operations.
