Description

Technical Field

[0001] This utility model relates to the technical field of sand and gravel processing devices, and in particular to a sand and gravel concrete separation device. Background Technology

[0002] Concrete is a building material mainly composed of a mixture of cement, sand, stone and water. It is one of the main materials in modern building structures. During the construction process on a construction site, the demolished concrete needs to be processed. Then, the crushed concrete is screened through a sand and gravel separation device to separate the sand and gravel, so that it can be recycled and reused. It is the main equipment for recycling and secondary processing of concrete residues.

[0003] A search revealed Chinese Patent Publication No. CN222566916U, which discloses a sand and gravel separation device based on concrete processing. The device includes a rotatable and tiltable separation chamber. Handrails on both sides of the chamber allow it to be lifted and rotated. When too many stones are screened and isolated inside the chamber, the chamber is lifted, and the baffle plate is pulled out of the disassembly slot, allowing the screened stones to be discharged through the slot. Once the chamber is fully lifted, all the stones inside can be discharged, making stone recycling very convenient and greatly improving the overall ease of use.

[0004] In actual use, the aforementioned separation device requires overcoming the weight of the separation chamber itself plus the weight of the stones when cleaning the stones at the separation point by pulling up the separation chamber. This significantly increases the difficulty of pulling up and separating the stones. At the same time, during the separation process, if the heavy separation chamber shifts even slightly, there is a risk of jamming, which will affect the use of the separation device and the efficiency of processing concrete residue. Therefore, a sand and gravel concrete separation device is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-2 This utility model provides an embodiment of a sand and gravel concrete separation device, including a processing table 1. The upper surface of the processing table 1 is provided with a discharge port 2. The bottom of the processing table 1 is fixedly connected to a discharge hopper 3. The screened material can enter the discharge hopper 3 through the discharge port 2, and then be discharged into a subsequent collection container or device through the discharge hopper 3. The upper surface of the processing table 1 is fixedly connected to a separation cylinder 4. The material can be put into the separation cylinder 4 for separation processing. The separation cylinder 4 is located directly above the discharge port 2. The material that has been screened inside the separation cylinder 4 will be discharged directly through the discharge port 2.

[0033] A fixed frame 5 is fixedly connected inside the separation cylinder 4. A support rod 6 is fixedly connected to the outer surface of the fixed frame 5. The end of the support rod 6 away from the fixed frame 5 is fixedly connected to the inner wall of the separation cylinder 4. An inverted bucket-shaped filter screen 7 is fixedly connected to the upper surface of the support rod 6. The support rod 6 can support and limit the bottom of the inverted bucket-shaped filter screen 7, thereby improving the stability and service life of the inverted bucket-shaped filter screen 7. The inner wall of the inverted bucket-shaped filter screen 7 is fixedly connected to the outer wall of the fixed frame 5, and the outer wall of the inverted bucket-shaped filter screen 7 is fixedly connected to the inner wall of the separation cylinder 4. The inverted bucket-shaped filter screen 7 can filter the material entering the separation cylinder 4. The stones that are screened out above the inverted bucket-shaped filter screen 7 will slide down the inclined surface of the inverted bucket-shaped filter screen 7 to the inner wall of the separation cylinder 4.

[0034] Reference Figures 2-4A scraper 8 is positioned above the inverted bucket-shaped filter screen 7, and a drive unit 9 is positioned on the outer side of the scraper 8. The drive unit 9 includes a mounting cavity 91, which is located inside the fixing frame 5. A motor 92 is fixedly connected to the bottom surface of the mounting cavity 91. The bottom of the mounting cavity 91 is sloping outwards. Heat dissipation holes (not directly shown in the figure) can be formed on the inner wall surface of the mounting cavity 91. Material entering the mounting cavity 91 through the heat dissipation holes can also be discharged along the sloping bottom surface. The motor 92... The top output end of motor 92 passes through the fixed frame 5. The top output end of motor 92 is fixedly connected to a rotating block 93. The upper end of rotating block 93 is set in a conical structure. The outer wall of rotating block 93 is fixedly connected to scraper 8. The bottom surface of scraper 8 is in contact with the upper surface of inverted bucket filter screen 7. When motor 92 starts, it will drive scraper 8 to rotate through rotating block 93. When scraper 8 rotates, it will push the material above inverted bucket filter screen 7, accelerating the screening speed of material and the sliding speed of stones.

[0035] A guide ring plate 10 is fixedly connected inside the separation cylinder 4. The inner ring of the upper surface of the guide ring plate 10 is inclined downwards. When material is poured onto the guide ring plate 10, the material can slide down along the inclined surface of the guide ring plate 10 to the center of the separation cylinder 4, so that the material can first reach the center of the inverted bucket-shaped filter screen 7 and then slide outwards for screening, improving the utilization rate of the screening area of ​​the inverted bucket-shaped filter screen 7. A discharge port 11 is opened on the left side surface of the separation cylinder 4. The bottom surface of the discharge port 11 is at the same level as the outer ring of the upper surface of the inverted bucket-shaped filter screen 7. The screened stones can be discharged... The waste material is discharged through the discharge port 11. A baffle 12 is slidably connected inside the discharge port 11. A fixed box 13 is fixedly connected to the left side of the separation cylinder 4. The baffle 12 can block the discharge port 11 to prevent unscreened materials from being discharged directly through the discharge port 11. When there are too many stones inside the separation cylinder 4, which affect the screening of materials, the baffle 12 can be pulled open to open the discharge port 11, so that the stones can be quickly discharged through the discharge port 11. During the discharge process, the motor 92 can be started to drive the scraper 8 to rotate, so that the scraper 8 can quickly push the stones to the discharge port 11 for discharge.

[0036] Reference Figure 1 and Figure 5A collection box 14 is inserted inside the fixed box 13. Stones discharged through the discharge port 11 will enter the collection box 14 for collection. The upper end of the right inner wall surface of the collection box 14 is chamfered 15. The chamfer 15 allows stones sliding down the outer wall of the separation cylinder 4 to slide down the inclined surface of the chamfer 15 into the collection box 14, avoiding the wall thickness of the collection box 14 from obstructing the falling of stones and causing stones to splash. The right surface of the collection box 14 is in contact with the left inner wall of the separation cylinder 4. A handle 16 is fixedly connected to the upper surface of the collection box 14, allowing workers to quickly pick up and clean the collection box 14 through the handle 16.

[0037] Working principle: The material is conveyed into the separation cylinder 4 along the inner wall. The material reaches the guide ring plate 10 and slides down the inclined surface of the guide ring plate 10 towards the center of the separation cylinder 4. This allows the material to reach the center of the inverted bucket-shaped filter screen 7 and then slide outwards for screening. Simultaneously, the motor 92 starts, driving the scraper 8 to rotate. This scraper 8 pushes the material and the screened stones, accelerating the screening speed and facilitating the sliding of the stones towards the inner wall of the separation cylinder 4. When there are many stones inside the separator 4 and cleaning of the slippage is required, the baffle 12 can be pulled open and the motor 92 can be started to drive the scraper 8 to rotate, so that the stones can quickly slide into the collection box 14 through the discharge port 11. There is no need to disassemble the entire separator, avoiding the difficulty of cleaning due to the large weight of the separator and the stones. After the stones are completely discharged, the baffle 12 can be inserted back into the discharge port 11, and the screening process can continue. The staff can quickly pick up and clean the collection box 14 through the handle 16. The structure is simple and the operation is convenient.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
