Description

Technical Field

[0001] This invention relates to the field of material conveying, and in particular to an environmentally friendly recycling device based on waste concrete. Background Technology

[0002] Waste concrete is the main solid waste generated from building demolition or construction. During the recycling process, large pieces of waste concrete are broken into smaller pieces. Impurities are removed during transportation, and coarse and fine aggregates are separated. The recycled coarse aggregate can replace natural crushed stone and be used to prepare recycled concrete for pouring non-load-bearing components (such as partition walls and subbases) or municipal engineering (such as roadbeds and plaza surfaces). The recycled fine aggregate can replace some natural sand and be used to make mortar, blocks, floor tiles and other building materials. During the recycling process of waste concrete, workers operate excavators to repeatedly place the waste concrete at the crusher for crushing. The crushed waste concrete is then transported by a conveyor belt. During this transport process, when the conveyor belt drops or transfers (such as when multiple conveyor belts are connected), the free fall of aggregates generates airflow disturbances, causing dust to escape and generate dust. In existing technologies, when using electrostatic precipitators for dust removal, the process of transporting waste concrete by excavators operated by workers is mostly not continuous, meaning the material feeding process is intermittent. Electrostatic precipitators typically use spray dust suppression to assist in dust collection. During intermittent material feeding, if the spray is not turned off in time after material is stopped, the humidity in the dust collection chamber will continue to rise. The dust already adsorbed on the plates will become excessively wet and clump together, causing blockages that require manual cleaning, affecting the dust removal effect and increasing operation and maintenance costs.

[0003] Therefore, it is necessary to propose an environmentally friendly recycling device based on waste concrete to solve the above problems. Summary of the Invention

[0008] Preferably, the feeding mechanism includes a fixed column fixedly connected to the top of the fixed frame. A movable sleeve is fitted on the surface of the fixed column away from the fixed frame. A receiving plate is fixedly connected to the upper end of the movable sleeve. A rectangular groove is formed at the bottom of the receiving plate. An inclined plate is slidably connected to the wall of the rectangular groove. An installation groove is formed on the surface of the inclined plate. A rotating plate is installed on the wall of the installation groove by a torsion spring. A baffle is fixedly connected to the right side of the inclined plate. A rotating ring is rotatably connected to the end of the fixed column near the fixed frame. A third spring is fixedly connected above the rotating ring. The end of the third spring away from the rotating ring is connected to the movable sleeve. A spiral groove is formed on the surface of the fixed column. A first protrusion is fixedly connected to the inner wall of the movable sleeve. The first protrusion is installed in conjunction with the spiral groove.

[0009] Preferably, L-shaped columns are symmetrically fixedly connected to the upper surface of the inclined plate. The surface of the L-shaped columns is provided with column grooves. T-shaped rods are slidably connected to the groove walls. A return spring is sleeved on the outer side of the T-shaped rod. A stop block is fixedly connected to one end of the T-shaped rod. A top block is fixedly connected above the L-shaped columns. A crossbar is fixedly connected to the surface of the top block. A fourth spring is sleeved on the outer side of the crossbar.

[0010] Preferably, a second protrusion is symmetrically fixedly connected to the edge of the receiving plate surface.

[0011] Preferably, a spring sheet is fixedly connected to the surface of the first rotating block next to the second rotating block.

[0012] Preferably, a cover plate is fixedly connected to the surface of the receiving plate away from the movable sleeve. A first sliding plate and a second sliding plate are fitted onto the surfaces of the receiving plate and the cover plate. One of the first sliding plates is slidably connected to the cover plate, and the other first sliding plate is slidably connected to the unloading plate. The second sliding plate is slidably connected to the first sliding plate. Connecting springs are symmetrically fixedly connected to the side of the two second sliding plates away from the receiving plate. The other ends of the plurality of connecting springs are all fixedly connected to the cover plate.

[0013] Compared with existing technologies, the present invention provides an environmentally friendly recycling device based on waste concrete, which has the following beneficial effects: This environmentally friendly waste concrete recycling device uses baffles and inclined plates to accumulate crushed waste concrete within a storage space formed by a receiving plate, inclined plates, and baffles. During this process, because the receiving plate is inclined, the crushed waste concrete gradually accumulates. The first rotating block contacts the surface of the L-shaped column and moves relative to it. The torsion spring at the connection between the second and first rotating blocks deforms. As the amount of crushed waste concrete gradually accumulates, the baffle separates from the first rotating block, and the fourth spring is compressed. When the rotating plate contacts the inclined portion of the receiving plate, an outlet for the crushed waste concrete is opened between the baffle and the rotating plate. The crushed waste concrete is placed on the surface of the discharge plate, and a fixed quantity is discharged at a time. The discharge plate moves away from the receiving plate, and the adjusting block moves relative to multiple trapezoidal grooves. This causes the discharge plate to vibrate during the conveying process, ensuring that the surface of the discharge plate is not blocked by the crushed waste concrete during each conveying operation.

[0014] This environmentally friendly recycling device based on waste concrete works by gradually increasing the amount of crushed waste concrete on the feeding plate. The feeding plate moves towards compressing the first spring, and the top of the lifting column contacts the lower surface of the feeding plate. The lifting column moves along with the feeding plate, compressing the fifth spring. The first and second pressure plates also move with the lifting column, forcing water from the storage tank through the connecting pipe towards the nozzle. This changes the humidity inside the dust collection chamber of the electrostatic precipitator, causing dust particles to condense and, under their own weight, facilitate rapid dust collection. During the process of the crushed waste concrete being discharged from the feeding plate, the elastic force of the fifth spring causes the first pressure plate and the lifting column to return to their initial positions. This means the water discharged from the storage tank is discontinuous. This discontinuous discharge of the crushed waste concrete prevents excessive dust agglomeration that could clog the equipment, thus ensuring the dust removal efficiency of the electrostatic precipitator.

[0017] 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.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4An environmentally friendly recycling device based on waste concrete includes a mounting frame 1, a horizontal column 11 disposed on the left side of the surface of the mounting frame 1, a feeding plate 12 slidably connected to the horizontal column 11 and the top of the mounting frame 1, a cover plate 13 fixedly connected to the top of the feeding plate 12, a bent pipe 14 fixedly connected to the surface of the cover plate 13, and an electrostatic precipitator 15 fixedly connected to the end of the bent pipe 14 away from the cover plate 13. A ring block 2 is symmetrically slidably connected to the surface of the mounting frame 1, and a vertical column 3 is slidably connected to the inner side of the ring block 2. Multiple vertical columns 3 are fixedly connected to the mounting frame 1. A first spring 4 is sleeved on the outer side of the vertical column 3, and a second spring 5 is symmetrically sleeved on the outer side of the horizontal column 11. A fixing frame 6 is fixedly connected to the left side of the mounting frame 1. A feeding mechanism 7 for quantitatively discharging crushed concrete is provided on the surface of the fixing frame 6. An auxiliary mechanism 8 for assisting dust collection is provided between the mounting frame 1 and the electrostatic precipitator 15. The auxiliary mechanism 8 includes a water tank 81 fixedly connected between the mounting frame 1 and the electrostatic precipitator 15. The top of the water tank 81 is symmetrically provided with connection holes 82. Lifting columns 83 are slidably connected to the walls of the connection holes 82. A fifth spring 84 is sleeved on the outside of the lifting columns 83. A first pressure plate 85 is fixedly connected below the multiple lifting columns 83. A sixth spring 86 is symmetrically fixedly connected to the lower surface of the first pressure plate 85. A second pressure plate 87 is fixedly connected to the end of the multiple sixth springs 86 away from the first pressure plate 85. The first pressure plate 85 and the second pressure plate 87 are both installed in conjunction with the inner wall of the water tank 81. Multiple connecting pipes 88 are fixedly connected to the top of the water tank 81 near the edge. A nozzle 89 is fixedly connected to the end of the multiple connecting pipes 88 away from the water tank 81. The multiple nozzles 89 are all fixedly connected to the electrostatic precipitator 15. It should be noted that, in the initial state, the receiving plate 73 and then the inclined plate 75 are at a high position. Under the elastic force of the connecting spring 734, the second sliding plate 733 can be in close contact with the receiving plate 73. One of the first sliding plates 732 is in close contact with the cover plate 731, and the other first sliding plate 732 is in close contact with the receiving plate 73. That is, in the accommodating space formed by the cover plate 13, the first sliding plate 732 and the second sliding plate 733, there are two outlets for the waste concrete after crushing to be discharged from the end of the discharge plate 12 away from the movable sleeve 72. During the operation of the electrostatic precipitator 15, the bent pipe 14 is close to the two outlets and can absorb and collect dust in the accommodating space formed by the cover plate 13, the first sliding plate 732 and the second sliding plate 733.

[0019] Please see Figure 1 and Figure 2A connecting ring 111 is symmetrically fixedly connected to the middle of the surface of the horizontal column 11. Both connecting rings 111 are fixedly connected to the lower surface of the feed plate 12. A connecting block 112 is symmetrically fixedly connected to the side of the lower surface of the feed plate 12 away from the connecting rings 111. A limiting post 113 is slidably connected below the connecting block 112. The two limiting posts 113 are fixedly connected to two of the annular blocks 2 respectively. The other two annular blocks 2 are fixedly connected to the horizontal column 11. It should be noted that the ring block 2, the limiting post 113 and the connecting ring 111 can limit the installation of the feeding plate 12, so that the receiving plate 73 can be adjusted in the vertical direction and in the direction along the axis of the horizontal post 11.

[0020] Please see Figure 1 , Figure 2 and Figure 4 One side of the feeding plate 12 is symmetrically fixedly connected with an adjusting block 121. The two adjusting blocks 121 are provided with a connecting frame 122 at the end away from the feeding plate 12. The connecting frame 122 is fixedly connected to the mounting frame 1. The surface of the connecting frame 122 is symmetrically and equidistantly provided with trapezoidal grooves 123. The trapezoidal grooves 123 are installed in conjunction with the adjusting block 121. It should be noted that as the amount of waste concrete after crushing on the surface of the feeding plate 12 gradually increases, the feeding plate 12 moves toward compressing the first spring 4, and relative movement occurs between the adjusting block 121 and the trapezoidal groove 123, which can drive the feeding plate 12 to move in a direction perpendicular to the connecting frame 122. Relative movement occurs between the connecting ring 111 and the horizontal column 11, and relative movement occurs between the limiting column 113 and the connecting block 112. One of the two second springs 5 ​​is compressed and the other is stretched, and the adjusting block 121 and the trapezoidal groove 123 do not separate. When the feeding plate 12 moves in the vertical direction, the feeding plate 12 can vibrate due to the interaction between the adjusting block 121 and the trapezoidal groove 123, ensuring that the waste concrete after crushing on the surface of the feeding plate 12 will not cause blockage during one feeding process. It should be noted that, as the waste concrete after crushing slides down the receiving plate 73, inclined plate 75 and baffle 78 onto the surface of the discharge plate 12, the amount of waste concrete after crushing on the surface of the discharge plate 12 gradually increases, relative movement occurs between the annular block 2 and the vertical column 3, the first spring 4 is compressed, and relative movement occurs between the adjusting block 121 and the multiple trapezoidal grooves 123. As screening proceeds, the amount of waste concrete after crushing on the surface of the discharge plate 12 gradually decreases. Under the elastic force of the first spring 4, the adjusting block 121 gradually returns to its initial position, and the waste concrete after crushing can be transported from the surface of the receiving plate 73 to the ground at the end of the discharge plate 12 away from the fixed column 71 and the movable sleeve 72 under its own gravity. During this process, the bottom of the feeding plate 12 contacts the top of the lifting column 83. The lifting column 83 moves together with the feeding plate 12, the fifth spring 84 is compressed, and the first pressure plate 85 and the second pressure plate 87 move together with the lifting column 83, pressing the water in the water storage tank 81 through the connecting pipe 88 to the nozzle 89, which sprays out from the nozzle 89. This changes the humidity inside the dust collection chamber of the electrostatic precipitator 15, which is used to collect dust, so that multiple dust particles can condense. Under their own gravity, the dust can be collected quickly. During the process of the crushed waste concrete being discharged from the surface of the feeding plate 12, the elastic force of the fifth spring 84 can drive the first pressure plate 85 and the lifting column 83 to return to their initial positions. That is, the water discharged from the water storage tank 81 is discontinuous. During the discontinuous discharge of the crushed waste concrete, excessive dust agglomeration is avoided, which can cause equipment blockage, thereby ensuring the dust removal effect of the electrostatic precipitator 15.

[0021] Please see Figure 1 and Figure 5 , Figure 6 , Figure 7 , Figure 8 The feeding mechanism 7 includes a fixed column 71 fixedly connected to the fixed frame 6. A movable sleeve 72 is fitted on the surface of the fixed column 71 away from the fixed frame 6. A receiving plate 73 is fixedly connected to the upper end of the movable sleeve 72. A rectangular groove 74 is opened at the bottom of the receiving plate 73. An inclined plate 75 is slidably connected to the wall of the rectangular groove 74. An installation groove 76 is opened on the surface of the inclined plate 75. A rotating plate 77 is installed on the wall of the installation groove 76 by a torsion spring. A baffle 78 is fixedly connected to the right side of the surface of the inclined plate 75. A rotating ring 711 is rotatably connected to the end of the fixed column 71 near the fixed frame 6. A third spring 712 is fixedly connected above the rotating ring 711. The end of the third spring 712 away from the rotating ring 711 is connected to the movable sleeve 72. A spiral groove 713 is opened on the surface of the fixed column 71. A first protrusion 714 is fixedly connected to the inner wall of the movable sleeve 72. The first protrusion 714 is installed in conjunction with the spiral groove 713. It should be noted that as crushed waste concrete accumulates on the surface of the receiving plate 73, both the movable sleeve 72 and the receiving plate 73 move towards the fixed frame 6 under the action of gravity. The first protrusion 714 moves relative to the spiral groove 713, and the third spring 712 is compressed. When the crushed waste concrete on the surface of the inclined plate 75 is gradually placed on the surface of the discharge plate 12, the elastic force of the third spring 712 causes the first protrusion 714 to move relative to the spiral groove 713 again during the discharge process. This allows the receiving plate 73 and the movable sleeve 72 to rotate, so that the crushed waste concrete can be dispersed and discharged onto the surface of the discharge plate 12 without accumulation, thus ensuring the conveying and discharging effect.

[0022] Please see Figure 8 and Figure 9 An L-shaped column 751 is symmetrically fixedly connected to the upper surface of the inclined plate 75. A column groove 752 is opened on the surface of the L-shaped column 751. A T-shaped rod 753 is slidably connected to the groove wall of the column groove 752. A return spring 754 is sleeved on the outside of the T-shaped rod 753. A stop block 755 is fixedly connected to one end of the T-shaped rod 753. A top block 756 is fixedly connected above the L-shaped column 751. A crossbar 757 is fixedly connected to the surface of the top block 756. A fourth spring 758 is sleeved on the outside of the crossbar 757. A positioning block 759 is fixedly connected to the surface of the receiving plate 73 below the two crossbars 757. The positioning block 759 is slidably connected to the crossbar 757. A first rotating block 7510 is rotatably connected to the surface of the receiving plate 73 next to the L-shaped column 751. A second rotating block 7511 is installed on the surface of the first rotating block 7510 through a torsion spring. A second protrusion is symmetrically fixedly connected to the edge of the surface of the receiving plate 73. It should be noted that the second protrusion can block the L-shaped column 751 and the inclined plate 75. After the crushed concrete gradually accumulates in the accommodating space formed by the inclined plate 75, the receiving plate 73 and the baffle 78, after the baffle 755 separates from the first rotating block 7510, when the L-shaped column 751 contacts the second protrusion, the rotating plate 77 can contact the inclined part on the surface of the receiving plate 73, so that a discharge port can be opened between the rotating plate 77 and the baffle 78 for the crushed waste concrete to be discharged. It should be noted that the process of conveying and unloading the crushed waste concrete is intermittent. This unloading method allows for centralized unloading, which in turn enables the concentrated treatment of dust during the unloading process, ensuring the effectiveness of dust control. It should be noted that the crushed waste concrete can accumulate in the storage space formed by the receiving plate 73, the inclined plate 75, and the baffle 78. During this process, the first rotating block 7510 contacts the surface of the L-shaped column 751 and moves relative to it. The torsion spring at the connection between the second rotating block 7511 and the first rotating block 7510 deforms. As the amount of crushed waste concrete gradually accumulates, the baffle 755 separates from the first rotating block 7510, and the fourth spring 758 is compressed. When the rotating plate 77 contacts the inclined part of the surface of the receiving plate 73, an outlet for the crushed waste concrete is opened between the baffle 78 and the rotating plate 77. The crushed waste concrete is placed on the surface of the discharge plate 12 for conveying and discharge.

[0023] Please see Figure 9 A spring sheet is fixedly connected to the surface of the first rotating block 7510 next to the second rotating block 7511; It should be noted that the spring sheet can assist the first rotating block 7510 and the second rotating block 7511 in resetting during the resetting process of the L-shaped column 751. Specifically, after the waste concrete from the crushed surface of the inclined plate 75 is discharged, the L-shaped column 751 moves away from the positioning block 759 under the elastic force of the fourth spring 758. The stop block 755 contacts the first rotating block 7510, causing the first rotating block 7510 to rotate. The spring plate contacts the surface of the receiving plate 73 and deforms. After the stop block 755 separates from the first rotating block 7510, the elastic force of the spring plate can ensure that the first rotating block 7510 and the second rotating block 7511 are reset.

[0024] Please see Figure 2 and Figure 4 A cover plate 731 is fixedly connected to the surface of the receiving plate 73 away from the movable sleeve 72. A first sliding plate 732 and a second sliding plate 733 are installed on the surfaces of the receiving plate 73 and the cover plate 731. One of the first sliding plates 732 is slidably connected to the cover plate 13, and the other first sliding plate 732 is slidably connected to the unloading plate 12. The second sliding plate 733 is slidably connected to the first sliding plate 732. Connecting springs 734 are symmetrically fixedly connected to the side of the two second sliding plates 733 away from the receiving plate 73. The other ends of the multiple connecting springs 734 are all fixedly connected to the cover plate 13.

[0025] It should be noted that counterweights can be symmetrically fixedly connected to the side of the mounting frame 1 away from the feeding plate 12; the setting of the counterweights lowers the center of gravity of the entire device, which can ensure the stability of the entire device during operation.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
