Description

Technical Field

[0001] This invention relates to the field of construction waste conveying technology, and specifically proposes a vibratory feeder for recycled aggregates based on the recycling of construction waste. Background Technology

[0002] In the construction industry, with the acceleration of urbanization, a large amount of construction waste is generated from the demolition of old buildings and the construction of new buildings. Sorting, crushing, removing impurities and recycling these wastes, and then screening them to convert them into recycled aggregates for reuse, is an important way to achieve resource conservation and environmental protection. On the production line of recycled aggregates, the vibrating feeder is a key pre-treatment equipment, which is usually used to perform preliminary screening and uniform feeding of the sorted, crushed and impurity-removed construction waste so that subsequent processes can carry out fine processing.

[0003] Existing vibrating feeder conveyors used for construction waste treatment typically include a vibrating trough that propels materials forward through vibration. However, due to the varying particle sizes of construction waste, existing feeders often struggle to effectively separate and synchronously transport large and small particles during screening and conveying, impacting the lifespan of downstream equipment such as crushers. After screening, the material distribution is usually uneven, especially in the width direction, where material tends to concentrate in a certain section. This results in uneven stress on the equipment when it subsequently enters the crusher or screening machine, affecting processing efficiency and equipment lifespan.

[0004] Therefore, there is an urgent need for a vibratory feeder conveyor for recycled aggregates based on the recycling of construction waste, which can effectively separate construction waste and ensure uniform material distribution and synchronous conveying efficiency. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a vibratory feeder conveyor for recycled aggregates based on the recycling of construction waste, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vibratory feeder for recycled aggregate based on the recycling of construction waste, comprising a closed elongated cavity with an inlet and an outlet, wherein a feed box is installed at the inlet of the elongated cavity.

[0007] The screening assembly includes multiple screening plates arranged along its length, the multiple screening plates being disposed inside a long cavity for screening construction waste into upper layer large particles and lower layer small particles.

[0008] A vibration mechanism is installed on the surface of the long cavity to drive the vibration of the entire long cavity.

[0009] Along the length of the long cavity, there are feeding area, spreading area and conveying area respectively.

[0010] A fabric feeding mechanism, installed in the fabric feeding area, is used to uniformly feed large and small particles.

[0011] Construction waste enters the long cavity through the feed box. Inside the feed area, the material is separated by a screening plate and vibration. Different particle sizes are moved to their respective distribution areas for uniform distribution, and then the material is uniformly conveyed through the conveying area.

[0012] Preferably, the sides of the plurality of screening plates are provided with transverse grooves, and a connecting rod is slidably installed inside the transverse grooves to connect the plurality of screening plates to form an integral structure.

[0013] Preferably, a support plate is fixedly installed inside the elongated cavity, the upper surface of the support plate is used to support the longitudinal edge of the screening plate, and an anti-clogging component is installed on the surface of the screening plate to prevent the screening plate from getting stuck.

[0014] Preferably, the anti-clogging component includes two symmetrically inclined guide plates, the lower ends of which extend below the screening plate. The upper openings of the two guide plates are larger than the lower openings. The surfaces of the guide plates abut against the surfaces of the support plates. A support spring is installed on the surface of the support plate for supporting the material on the surface of the screening plate.

[0015] Preferably, an installation groove is provided inside the elongated cavity at the position corresponding to the transverse groove. The width of the installation groove is smaller than the width of the transverse groove, and the height of the installation groove is the same as the height of the transverse groove.

[0016] Preferably, the length of the connecting rod is the same as the length of the mounting groove, and anti-detachment blocks are provided at both ends of the connecting rod, with the surface of the anti-detachment blocks abutting against the end of the long cavity.

[0017] Preferably, the fabric distribution mechanism includes multiple distribution plates, which are integrally formed and evenly distributed. A motor for driving the multiple distribution plates to rotate is installed inside the elongated cavity.

[0018] Preferably, a suspension frame is installed inside the elongated cavity, and the fabric-making mechanism is installed inside the suspension frame.

[0019] Preferably, the length of the guide plate is the same as the length of the screening plate.

[0020] Preferably, the two motors are located on opposite sides of the elongated cavity.

[0021] The present invention has the following advantages or beneficial effects: The vibrating feeder conveyor for recycled aggregate based on the recycling of construction waste sets up a feeding zone and installs a screening component inside it. Driven by the vibration mechanism, it realizes the synchronous screening of construction waste during the conveying process. Small particles fall through the screening plate to the lower layer, while large particles remain in the upper layer, realizing the effective separation and parallel conveying of the upper and lower layers, avoiding material accumulation. In addition, a feeding mechanism is set up in the feeding zone. The forced action of the feeding mechanism ensures that the material entering the conveying zone and even the subsequent crusher or screening machine has a uniform material layer thickness and flow rate per unit time in the entire width direction. At the same time, this structure can also fill the gaps by material accumulation, realizing continuous and uniform feeding. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1 As shown, this invention provides a vibratory feeder conveyor for recycled aggregate based on the recycling of construction waste. The main body of the conveyor is a closed elongated cavity 1 welded from wear-resistant steel plates. The cross-section of the elongated cavity 1 is rectangular. A feed inlet is provided at the top of one end of the elongated cavity 1, and a feed box 8 is welded and fixed at the feed inlet. The feed box 8 is funnel-shaped, wider at the top and narrower at the bottom, and is used to receive construction waste from the upstream crushing process and guide it smoothly into the cavity. A discharge outlet is provided at the bottom of the other end of the elongated cavity 1, which is used to discharge the processed material to the next process. The entire elongated cavity 1 is driven by a vibration mechanism 3 installed on its surface to generate high-frequency linear vibration to realize the throwing and conveying of materials. The vibration mechanism 3 can be a motor-driven vibrator or an electromagnetic vibrator.

[0035] like Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, inside the long cavity 1, it is divided into three functional areas along its length (i.e. the material conveying direction): feeding area 4, material distribution area 5 and conveying area 6. These three areas are physically connected, but are functionally distinguished by the layout of their internal components.

[0036] A screening assembly 2 is installed in the feeding area 4. The screening assembly 2 includes multiple screening plates 21 arranged at equal intervals along the length of the long cavity 1. The screening plates 21 are rectangular steel plates with circular or square screen holes evenly opened on them. In this embodiment, square screen holes are selected. The screening plates 21 are installed at an inclination inside the long cavity 1, with the feeding end slightly higher than the discharging end. The inclination angle is preferably 5°-15° to facilitate the forward movement and screening of materials under vibration.

[0037] To improve the structural stability of the screening plates 21, each screening plate 21 has a through transverse groove 9 on both sides (along the width direction). The transverse groove 9 is a rectangular hole, and its length direction is consistent with the width direction of the screening plate 21. A continuous connecting rod 22 passes through the transverse groove 9 on the same side of all screening plates 21. The height of the transverse groove 9 is slightly larger than the diameter of the connecting rod 22, so that the connecting rod 22 can slide up and down within a small range in the transverse groove 9 to adapt to vibration and material impact. At the same time, through this connecting rod 22, multiple independent screening plates 21 can be connected into a whole, so that they can work together to bear the force when subjected to the impact of large pieces of material, and avoid individual screening plates 21 from deforming or being damaged due to excessive force.

[0038] like Figure 1 and Figure 5 As shown, horizontal support plates 11 are welded and fixed on the inner two side walls of the long cavity 1 along the length direction. The upper surface of the support plate 11 is used to support the long edge of the screening plate 21 and provide a stable foundation for the screening plate 21. It should be noted that the screening plate 21 is not directly and rigidly fixed on the support plate 11, but is placed on top of the support plate 11.

[0039] Multiple support springs 13 are also installed on the surface of the support plate 11. The lower end of the support spring 13 is fixed in a pre-set blind hole on the support plate 11, and the upper end abuts against the lower surface of the screening plate 21. The support springs 13 are distributed in a matrix to elastically support the screening plate 21, provide buffer for the screening plate 21, reduce rigid damage caused by the impact of large pieces of material, and at the same time help the screening plate 21 maintain a slight floating during vibration, which helps to prevent material jamming.

[0040] like Figures 4-8 As shown, considering that some particles and debris can easily get stuck in the gaps between the screening plates 21 or in the gaps between the screening plates 21 and the cavity wall, leading to vibration failure or damage to the screening plates, this embodiment has anti-blocking components 12 installed on both sides of the screening plates 21.

[0041] The anti-clogging component 12 includes two symmetrically inclined guide plates 121, which are located on both sides of the screening plate 21 in the width direction. The lower end of the guide plate 121 extends inclinedly towards the center of the elongated cavity 1, while the upper end of the guide plate 121 extends towards both sides of the elongated cavity 1. The guide plate 121 and the screening plate 21 are fixed by welding. The upper opening width of the two guide plates 121 is equal to the internal width of the elongated cavity 1, while the lower opening width is significantly reduced, forming a funnel-shaped guide channel that is wider at the top and narrower at the bottom. The lower edge of the guide plate 121 is not connected to other components and is in a free state or rests against the side of the support plate 11.

[0042] The preferred inclination angle of the guide plate 121 is 30°-60°. This structure can guide the small particles that have passed through the screening plate 21 after screening to slide smoothly down the inclined surface to the lower space of the long cavity 1. On the other hand, its smooth and inclined surface can effectively prevent slender debris from getting stuck in the dead corner area between the edge of the screening plate 21 and the cavity wall. Once debris slides into this area, due to the lack of a horizontal support surface and the combined effect of vibration and gravity, it will slide away quickly along the inclined surface of the guide plate 121, thus fundamentally playing a role in preventing blockage.

[0043] In this embodiment, the length of the guide plate 121 is preferably set to be the same as the length of the screening plate 21 to ensure anti-clogging protection for the entire length of the screening plate 21.

[0044] To ensure the stability and reliability of the screening component 2 and prevent it from shifting during long-term vibration, mounting grooves 122 are provided on the inner wall of the long cavity 1 at positions corresponding to the connecting rod 22. The mounting groove 122 is not a simple hole, but a groove with a specific shape formed by the indentation from the inner wall of the long cavity 1 to the outer wall. The vertical height of the mounting groove 122 is the same as the height of the horizontal groove 9, but the horizontal width (i.e. the opening width of the mounting groove 122) is smaller than the width of the horizontal groove 9.

[0045] Meanwhile, the total length of the connecting rod 22 is the same as the distance between the bottoms of the two opposing mounting slots 122. Each end of the connecting rod 22 is fixedly equipped with an anti-detachment block 123. When the screening plate 21 does not need to be replaced, the connecting rod 22 is completely inside the transverse groove 9 and will not affect the longitudinal movement of the screening assembly 2. If debris gets stuck inside the screen hole and affects the material conveying, the screening plate 21 needs to be replaced. When the screening plate 21 needs to be replaced, the connecting rod 22 is moved into the mounting slot 122. At this time, the screening assembly 2 is firmly locked in the long cavity 1. Then, the transverse groove 9 of the new screening plate 21 is aligned with the position of the connecting rod 22 and gradually pushed into the long cavity 1. The old screening plate 21 is pushed out. After all replacements are completed, the connecting rod 22 is moved back into the mounting slot 122, thus achieving replacement without stopping the machine.

[0046] like Figures 1-4 As shown, after screening in the feeding zone 4, the large particles in the upper layer move forward on the surface of the screening plate 21, while the small particles in the lower layer move forward at the bottom of the long cavity 1 (i.e., below the guide plate 121). The two layers move in parallel and enter the distribution zone 5. A distribution mechanism 7 is installed in the distribution zone 5. The distribution mechanism 7 is used to evenly distribute the large and small particles in the upper and lower layers, making their distribution in the width direction more uniform and eliminating material segregation caused by screening.

[0047] The material distribution mechanism 7 includes a rotating shaft and multiple material distribution plates 71 fixedly mounted on the rotating shaft. The material distribution plates 71 are evenly distributed along the axial direction of the rotating shaft and are integrally formed (e.g., made by casting or welding a composite beam) to ensure strength and consistency. Each material distribution plate 71 is radially shaped and its rotation radius covers most of the height range from the bottom of the long cavity 1 to the top of the upper material, thus enabling it to act on both the upper and lower materials simultaneously.

[0048] A suspension bracket 10 is welded and fixed inside the long cavity 1. The suspension bracket 10 spans across the fabric area 5. The two ends of the rotating shaft of the fabric mechanism 7 are rotatably mounted on the suspension bracket 10 through bearing seats. Two motors 72 are installed on the outside of the long cavity 1. The two motors 72 are located on both sides of the long cavity 1 and are connected to the two ends of the rotating shaft through a coupling to achieve synchronous drive. The dual motors 72 drive can provide sufficient torque and ensure the smooth operation of the fabric mechanism 7, while providing sufficient installation space.

[0049] When the material enters the feeding zone 5, the motor 72 drives the distribution plate 71 to rotate at a low speed. The rotating distribution plate 71 forcibly stirs, agitates, and redistributes the accumulated or segregated material: for the large particles in the upper layer, it disperses them from the middle of the accumulation area to both sides; for the small particles in the lower layer, it agitates them to make the material surface more even. Through this action, it ensures that the upper and lower layers of material have a uniform material layer thickness and flow rate per unit time in the entire width direction before entering the next area. At the same time, it can effectively accumulate excess material to fill the gap when there is too little material, and further achieve uniform feeding.

[0050] After being evenly distributed, the upper and lower layers of material continue to be separated and enter the conveying zone 6. The conveying zone 6 is a smooth trough with no other components inside, and it still has the ability to separate materials. In the conveying zone 6, the material is evenly and stably thrown and conveyed towards the discharge port under the continuous high-frequency vibration of the vibration mechanism 3, and finally discharged to the downstream equipment.

[0051] The complete working process of this embodiment is as follows: Construction waste enters the feeding area 4 from the feeding box 8. Driven by the vibration mechanism 3, the material moves forward. At the same time, small particles fall through the screening plate 21 and fall into the lower layer under the guidance of the anti-blocking component 12. Large particles remain on the screening plate 21. The connecting rod 22 and the support spring 13 ensure the stability and buffering capacity of the screening plate 21, and also have a certain self-cleaning ability. The layered material enters the distribution area 5. The dual motors 72 drive the distribution plate 71 to rotate, forcibly stirring and leveling the upper and lower layers of material, reducing segregation, achieving uniform distribution in the width direction, and continuous uniform feeding. The uniformly distributed material enters the conveying area 6 and is smoothly and continuously conveyed to the discharge port under the action of vibration, completing the entire feeding and screening process.
