Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete waste treatment technology, and in particular to a concrete waste separation device. Background Technology
[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering. During construction, a large amount of concrete waste is generated; directly discarding it would be wasteful.
[0003] Chinese Patent 202320415808.0 discloses a concrete waste crushing and separation device, relating to the field of concrete waste treatment technology. The invention includes a separation device and a crushing device. The separation device includes a base frame with slide rails on both sides. Support bars are mounted on the base frame, and a screening component is movably mounted on the slide rails. A collecting component is mounted on the support bars. The screening component includes a slider movably mounted inside the slide rails. A fixing bar is mounted on the upper part of the slider, and a rotating shaft is movably mounted at the end of the fixing bar. A drive gear is mounted at the end of the rotating shaft, and a transmission chain is connected to the drive gear. A transmission plate is mounted on the transmission chain, and the transmission plate has several circular through holes arranged in an equally spaced array. The transmission chain is encased in a shell, and a connecting rod is connected to the outside of the transmission chain shell. A protective plate is connected to the connecting rod. This invention is a concrete waste crushing and separation device with good performance.
[0004] However, the separation effect of the aforementioned separation equipment is still limited. When concrete waste falls onto the conveyor plate, the separation of concrete blocks and sand is mainly achieved by several circular through-holes distributed on the conveyor plate. The principle is that sand particles are relatively small and can pass through these circular through-holes, while concrete blocks, due to their larger size, are left on the conveyor plate, thus achieving separation. However, this method is still limited in its separation effect on concrete blocks and sand. Some slightly larger sand particles may get stuck at the through-holes and cannot pass through smoothly, resulting in incomplete separation. Furthermore, although the aforementioned separation equipment drives its conveyor plate to slide back and forth, some sand may still remain on the conveyor plate and not enter the circular through-holes. Therefore, a concrete waste separation device is proposed to solve the above problems. Utility Model Content

The interior of the mounting rings 1 is connected to the outer end face of the drive shaft 14 via multiple connecting rods 18 arranged in a ring array.
[0033] A drive assembly is provided on the side of the separation housing 10. One end of the drive shaft 14 is connected to one side of the inner wall of the separation housing 10, and the other end of the drive shaft 14 passes through the other side of the inner wall of the separation housing 10 and is connected to the drive assembly.
[0034] The screening assembly includes multiple mounting frame supports 17 arranged in a ring array. Adjacent mounting frame supports 17 are connected by hinges, and the two sides of the mounting frame supports 17 are located between the mounting rings 1. The screening plate 2 is detachably connected inside the mounting frame supports 17.
[0035] A feeding ring 3 is provided at the edge of the mounting ring 1 on one side, and a feeding assembly is provided at the upper edge of the separation shell 10. The discharge end of the feeding assembly is located inside the feeding ring 3. The mounting rings 1 on both sides, the feeding ring 3 and the drive shaft 14 are coaxially arranged, and the drive shaft 14 is inclined.
[0036] Support components are provided on both sides of the detachable housing 10, thereby providing support for the detachable housing 10.
[0037] In this invention, when in use, the drive assembly is activated, which drives the drive shaft 14 to rotate, and through multiple connecting rods 18 drives the mounting rings 1 on both sides to rotate. When the mounting rings 1 on both sides rotate, they can drive the screening assembly and the feeding ring 3 to rotate. At this time, concrete waste is added through the feeding assembly. This concrete waste enters the rotating screening assembly through the feeding ring 3 and rotates, thereby separating the concrete blocks and sand in the concrete waste.
[0038] When the mounting rings 1 on both sides rotate, they can drive the mounting outer frame brackets 17 distributed in multiple ring arrays to rotate. When the mounting outer frame brackets 17 rotate, they can also drive the screening plate 2 to rotate, thereby separating concrete blocks and sand in concrete waste.
[0039] When the screening plate 2 is damaged or a screen with a different aperture needs to be used, the screening plate 2 can be removed from the mounting frame bracket 17 and replaced with a screen plate 2 to fix it on the mounting frame bracket 17; the aperture is preferably hexagonal honeycomb arrangement.

[0042] In an optional embodiment, the inner diameter of the feeding ring 3 is the same as the inner diameter of the mounting ring 1, and the inner wall of the feeding ring 3 is smooth.

When the drive shaft 14 rotates, it can drive the mounting rings 1 on both sides to rotate through multiple connecting rods 18. When the mounting rings 1 on both sides rotate, they can drive the screening component and the feeding ring 3 to rotate, thereby improving the screening efficiency and effect.
[0046] In an optional embodiment, the feeding assembly includes a feeding hopper 5, a mounting frame 6, and a feeding pipe 4. The mounting frame 6 is located at the highest point of the upper edge of the separation housing 10. The feeding pipe 4 is fixed inside the mounting frame 6.

The concrete waste can enter the feeding ring 3 through the feed pipe 4. The concrete waste entering the feeding ring 3 can enter the rotating screening component to screen the concrete blocks and sand in the concrete waste.
[0048] In an optional embodiment, a second discharge hopper 12 and a first discharge hopper 11 are included. Both the second discharge hopper 12 and the first discharge hopper 11 are located at the bottom of the separation shell 10, and the first discharge hopper 11 is located at the bottom between the two first discharge hoppers 11, and the second discharge hopper 12 is located to the left of the first discharge hopper 11.
[0049] It should be noted that the sand falling through the screening component can be discharged through the first discharge hopper 11, while the screened concrete blocks can be discharged through the second discharge hopper 12.
[0050] In an optional embodiment, an inclined block 13 is provided on the inner bottom wall of the separation shell 10, with the inclined surface of the inclined block 13 facing the side of the first discharge hopper 11.
[0051] It should be noted that, via the drive shaft 14, the falling sand will fall onto the inclined surface of the drive shaft 14, and then the sand will mix with the inclined surface of the drive shaft 14 and fall into the first discharge hopper 11.
[0052] In an optional embodiment, the support assembly includes a side plate 8 and support columns 9. Both sides of the separate housing 10 are connected to the side plate 8 respectively. A plurality of support columns 9 are spaced apart at the bottom of the side plate 8 and the support columns 9 are vertically arranged.
