Detailed Implementation
[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the waste concrete brick and tile processing device of this embodiment includes a first cylinder 1, a crushing component 2 and a first screening component 3, and the height direction of the first cylinder 1 is defined as the up and down direction.
[0025] The first cylinder 1 has a feed inlet 11 at the top and a first discharge outlet at the bottom. A guide plate 4 is provided inside the first cylinder 1 corresponding to the feed inlet 11. A support ring 12 is fixed inside the first cylinder 1, and a second discharge outlet 13 is provided corresponding to the support ring 12. Optionally, a bracket 5 composed of multiple vertical rods is provided on the outer side or bottom of the first cylinder 1 to raise the first cylinder 1 to a set height, facilitating the collection of granular materials generated after brick and tile crushing from the first discharge outlet.
[0026] The crushing assembly 2 includes an impact hammer 21, which is located in the inner cavity of the first cylinder 1 and is used to crush bricks and tiles to generate granular material.
[0027] The first screening component 3 includes a screen frame 31 and a screen 32. The screen frame 31 is elastically connected to the support ring 12 and is movable in the vertical direction. The screen frame 31 has an annular structure and its outer wall fits against the inner cavity of the first cylinder 1. The screen 32 is disposed on the screen frame 31 and is used to allow a portion of the particulate material to pass through. The screen frame 31 has a discharge position. At the discharge position, the screen frame 31 is located below the second discharge port 13 so that another portion of the particulate material can be discharged through the second discharge port 13.
[0028] Specifically, multiple top support springs 33 are provided between the screen frame 31 and the support ring 12. The two ends of the top support springs 33 are fixedly connected to the screen frame 31 and the support ring 12 respectively. Optionally, the top support springs 33 are equipped with telescopically adjustable damping rods. The damping rods constrain the top support springs 33 to prevent the top support springs 33 from failing elastically under compression.
[0029] Below the second discharge port 13, there is a guide hopper 14. The guide hopper 14 is inclined so that the granular material discharged through the second discharge port 13 can slide down along the guide hopper 14.
[0030] In use, the waste concrete brick and tile processing device of this invention adds waste concrete bricks and tiles into the first cylinder 1 through the feed inlet 11. The bricks and tiles move towards the impact hammer 21 through the guide plate. The impact hammer 21 crushes the bricks and tiles. The crushed granular material falls onto the screen 32. Through the impact of the granular material on the screen 32 and the elastic connection between the screen frame 31 and the support ring 12, the screen frame 31 drives the screen 32 to vibrate periodically in the up and down direction, further realizing the screening effect of the granular material. Some granular material falls into the first discharge port through the screen 32, and some granular material accumulates on the screen 32. When the screen frame 31 moves down to below the second discharge port 13, the granular material accumulated on the screen 32 can be discharged through the second discharge port 13.
[0031] The waste concrete brick and tile processing device of this invention constrains the movement direction of the bricks and tiles by setting a guide plate 4, which facilitates the crushing operation of the impact hammer 21 and improves the crushing efficiency. At the same time, the reciprocating movement of the screen frame 31 in the up and down direction filters the particulate material generated after the bricks and tiles are crushed. The material that passes through the filter screen is discharged through the first discharge port, and the particulate material that does not pass through the filter screen is discharged through the second discharge port 13, which facilitates the separation of particulate material and improves the resource utilization rate.
[0032] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, it also includes a second screening component 6. The first cylinder 1 is provided with a third discharge port located below the support ring 12. The second screening component 6 includes a spray pipe 61, which is located below the support ring 12. The spray pipe 61 is used to spray air into the inner cavity of the first cylinder 1 to drive a portion of the particulate material to be discharged through the third discharge port.
[0033] In this embodiment, by setting up a spray pipe 61 and a third discharge port, air can be delivered into the inner cavity of the first cylinder 1 through the spray pipe 61. Combined with the differences in material density and mass, the lighter part of the granular material passing through the filter screen can move with the air under the action of wind force and then be discharged from the third discharge port, so as to facilitate further separation of the granular material passing through the filter screen, improve screening efficiency, improve separation effect, and thus improve resource utilization rate.
[0034] Optionally, a collecting pipe 15 is connected to the first cylinder 1 corresponding to the third discharge port, and a collecting box is provided at the end of the collecting pipe 15. The collecting box is used to collect the particulate material discharged from the third discharge port.
[0035] In some embodiments, such as Figure 2 and Figure 4 As shown, it also includes a second cylinder 7, which is disposed inside the first cylinder 1 and located below the third discharge port. The outer wall of the second cylinder 7 is in contact with the inner wall of the first cylinder 1. The second cylinder 7 is provided with an airflow cavity extending in the circumferential direction. One end of the injection pipe 61 is connected to the airflow cavity and the other end is sealed. The injection pipe 61 is provided with multiple injection ports in the circumferential direction. The opening direction of the injection ports is set at an angle to the radial direction of the second cylinder 7 to generate vortices in the first cylinder 1.
[0036] In this embodiment, an airflow cavity is provided to facilitate the supply of air to the jet pipe 61. By providing a second cylinder 7, the structural strength of the lower part of the first cylinder 1 is enhanced, and the collection of particulate material passing through the filter screen is facilitated, allowing the particulate material to be discharged from the first discharge port. The opening direction of the jet nozzle on the jet pipe 61 is set at an angle to the radial direction of the second cylinder 7, which facilitates the generation of vortices in the inner cavity of the first cylinder 1 located below the screen 32, further facilitating the separation of particulate material passing through the filter screen, improving screening efficiency, and achieving good separation effect, thereby improving the resource utilization rate.
[0037] In some embodiments, such as Figure 4 As shown, multiple spray pipes 61 are provided, and the spray pipes 61 are arranged in an array along the axis of the second cylinder 7 to further improve the vortex effect in the first cylinder 1, realize further separation of particulate materials passing through the filter screen, improve screening efficiency, and improve separation effect, thereby improving resource utilization rate.
[0038] Optionally, the injection pipes 61 are arranged in a ring array along the axis of the second cylinder 7, with at least one column in the radial direction of the second cylinder 7, and at least two in each column spaced circumferentially along the axis of the second cylinder 7.
[0039] In some embodiments, such as Figure 4 As shown, the inner wall of the second cylinder 7 is spirally provided with a flow divider 71. By setting the flow divider 71 and combining it with the airflow injection direction of the injection pipe 61, the particulate material forms a stable swirling motion inside the first cylinder 1. As a result, the particulate material quickly settles to the bottom of the first cylinder 1, and the dispersed particulate material is further cut and separated to ensure separation efficiency and effect.
[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, it also includes an air pump 62. The output end of the air pump 62 is provided with an air delivery pipe 63. The other end of the air delivery pipe 63 passes through the first cylinder 1 and the second cylinder 7 and communicates with the airflow cavity. By setting the air pump 62, it is convenient to deliver air into the injection pipe 61. It is easy to operate and easy to set up.
[0041] In some embodiments, such as Figure 2 and Figure 3 As shown, the crushing component 2 includes a drive motor 22, which is fixed inside the first cylinder 1 by a support shaft. The output shaft of the drive motor 22 is vertically arranged, and the impact hammer 21 is fixedly arranged on the output shaft of the drive motor 22. Optionally, the impact hammer 21 is connected to the output shaft of the drive motor 22 by a coupling. The drive motor 22 is used to drive the impact hammer 21 to rotate in order to crush the bricks and tiles.
[0042] In this embodiment, by setting a drive motor 22, it is easy to drive the impact hammer 21 to rotate, thereby making it easier for the impact hammer 21 to impact and crush bricks and tiles. It is easy to install, reliable in operation, and has good stability.
[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the guide plate 4 has an arc-shaped structure and is provided with multiple arc-shaped grooves. The arc-shaped grooves are spaced apart along the circumference of the guide plate 4, and the radius of curvature of the arc-shaped grooves is greater than the radius of rotation of the impact hammer 21.
[0044] In this embodiment, by setting the guide plate 4 as an arc plate, it is easy for the bricks and tiles to slide along the guide plate 4, thereby improving the crushing effect of the impact hammer 21 on the bricks and tiles. By setting the arc groove in the guide plate 4, it is easy to ensure that the bricks and tiles can move along the predetermined trajectory during the impact crushing process and avoid accumulation or jamming, thereby improving the crushing effect. The radius of curvature of the arc groove is set to be greater than the radius of rotation of the impact hammer 21 to avoid the impact hammer 21 from colliding with the guide plate 4, thereby improving the service life of the guide plate 4 and the impact hammer 21.
[0045] In some embodiments, the impact hammer 21 includes a hammer body and a plurality of conical protrusions disposed on the hammer body. The plurality of conical protrusions are spaced apart along the circumference of the hammer body. The design of the conical protrusions enhances the impact force of the impact hammer 21 when crushing bricks and tiles, thereby improving the crushing efficiency.
[0046] In some embodiments, the impact hammer 21 is eccentrically located on the output shaft of the drive motor 22. Through the eccentric setting of the impact hammer 21, a vibration effect can be generated when the impact hammer 21 impacts and crushes the bricks and tiles, thereby further improving the crushing efficiency.
[0047] In some embodiments, the screen frame 31 is inclined, which facilitates the granular material accumulated on the screen mesh 32 to slide down along the inclined direction of the screen frame 31, thereby facilitating the discharge of the granular material accumulated on the screen mesh 32 through the second discharge port 13, thus improving screening efficiency, separation effect, and resource utilization rate.
[0048] Preferably, the second discharge port 13 is set at the lowest position of the screen frame 31.
[0049] In some embodiments, such as Figure 2 and Figure 3 As shown, the top surface of the screen frame 31 is provided with a plurality of protruding units 34 at intervals along the circumference. The protruding units 34 are used to guide the granular material and / or crush the granular material when the screen frame 31 moves in the vertical direction.
[0050] In this embodiment, by setting a protruding unit 34 on the screen frame 31, the granular material can be further crushed by impact with the protruding unit 34 during the falling process. At the same time, the granular material accumulated on the filter screen can move towards the second discharge port 13 under the guidance of the protruding unit 34, so as to facilitate the discharge of the granular material accumulated on the screen 32 through the second discharge port 13, thereby improving the screening efficiency, the separation effect, and the resource utilization rate.
[0051] Optionally, the protrusion unit 34 is a conical protrusion or a hemispherical protrusion.
[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, it also includes a belt conveyor 8, which is located below the first discharge port. The belt conveyor 8 is used to transport the granular material from the first discharge port. The belt conveyor 8 facilitates the transfer of the granular material discharged from the first discharge port, resulting in high separation efficiency.
[0053] Preferably, the belt conveyor 8 is equipped with a guide cylinder 81 with a circular or rectangular cross-section. The guide cylinder 81 is set corresponding to the first discharge port. The first discharge port is connected to a guide pipe 16 with its end extending into the guide cylinder 81. The guide cylinder 81 and the guide pipe 16 facilitate the collection of particulate material discharged from the first discharge port, avoiding material splashing and making it green and environmentally friendly.
