Description

Technical Field

[0001] This invention relates to the field of concrete processing equipment technology, and in particular to a device for processing recycled concrete aggregates. Background Technology

[0002] Recycled concrete refers to new concrete made by crushing and pulverizing waste concrete blocks, then using them as aggregate in new concrete. This is done by mixing the recycled concrete with other aggregates in a specific ratio, partially or completely replacing sand and gravel, and then adding cement and water. The crushing of recycled concrete aggregate is typically done using crushing rollers. Because waste concrete blocks vary in size, a preliminary crushing step is usually added to ensure the crushing effect of the rollers. This involves first crushing large pieces of waste concrete into smaller fragments, which are then further crushed into aggregate. This prevents the concrete blocks from being too large to be properly gripped between the rollers. For example, a recycled concrete aggregate processing device disclosed in authorization announcement number CN221656652U uses a crushing roller for the preliminary crushing step. However, this preliminary crushing step still relies on the crushing rollers, which has certain drawbacks. Some relatively smooth, near-spherical concrete blocks may slip between the rollers and not be easily gripped, potentially causing them to bounce or roll, thus affecting the crushing efficiency.

[0069] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0070] like Figures 1 to 8 As shown, this embodiment discloses a recycled concrete aggregate processing device, including a feeding hopper 1, a crushing cylinder 2 is arranged below the feeding hopper 1, a fixed grinding disc 3 and two movable grinding discs 4 are arranged inside the crushing cylinder 2, the fixed grinding disc 3 is fixedly arranged in the middle of the crushing cylinder 2, and the two movable grinding discs 4 are slidably arranged in the crushing cylinder 2 on both sides of the fixed grinding disc 3, a first discharge port 2-1 is arranged on the crushing cylinder 2 below the fixed grinding disc 3, and an arc-shaped gate mechanism 5 is arranged on the first discharge port 2-1.

[0071] The moving grinding disc 4 includes a fixed-axis disc 4-1, a rotating ring disc 4-2 sleeved on the outer side of the fixed-axis disc 4-1, and an outer ring disc 4-3 sleeved on the outer side of the rotating ring disc 4-2. The fixed-axis disc 4-1 and the outer ring disc 4-3 are connected to the transverse movement mechanism 6, and the rotating ring disc 4-2 is connected to the rotary drive mechanism 7. The fixed grinding disc 3 is provided with protrusions 3-1, and crushing teeth 4-4 are provided on the surfaces of the fixed-axis disc 4-1, the rotating ring disc 4-2, and the outer ring disc 4-3 facing the fixed grinding disc 3. In this embodiment, the transverse movement mechanism 6 is fixedly disposed at both ends of the grinding cylinder 2, and the rotary drive mechanism 7 is slidably disposed on the grinding cylinder 2.

[0072] During operation, the material (waste concrete blocks) is fed into the feed hopper 1. The material falls between the fixed grinding disc 3 and the moving grinding disc 4. The transverse movement mechanism 6 is activated, which pushes the moving grinding disc 4 towards the fixed grinding disc 3, trapping the material in the middle. During this movement, the protrusions 3-1 and the crushing teeth 4-4 crush the material. The rotary drive mechanism 7 is then activated, causing the rotating disc 4-2 to rotate. Simultaneously, the crushing teeth 4-4 on the rotating disc 4-2 also rotate. This grinding effect enhances the crushing effect on the material trapped in the middle. Furthermore, the rotation of the rotating disc 4-2 changes the gaps between the crushing teeth 4-4, preventing large pieces from getting stuck between them. After the grinding action is completed, the arc-shaped gate mechanism 5 is opened, and the material falls into the crushing box 8 below for the next process.

[0073] It should be noted that the appendix Figure 2 To facilitate the display of the transverse movement mechanism 6, the moving grinding disc 4 and the rotation drive mechanism 7 on the right side of the crushing cylinder 2 are not shown.

[0074] A crushing box 8 is provided below the crushing cylinder 2. The crushing box 8 is equipped with a crushing device 9 and a screening mechanism 10. A coarse material outlet 11 is provided on the side wall of the crushing box 8, and a fine material outlet 12 is provided at the bottom of the crushing box 8.

[0075] like Figure 2As shown, the feed inlet of the crushing box 8 is equipped with two inwardly inclined feed plates 8-2. The crushing device 9 includes two crushing rollers 9-1, with the lower ends of the two feed plates 8-2 facing the space between the two crushing rollers 9-1. The crushing rollers 9-1 are rotatably connected inside the crushing box 8, and one end of the crushing rollers 9-1 passes through the side wall of the crushing box 8 and is connected to an external motor, which drives them to rotate and crush. When the material, after being initially crushed by the fixed grinding disc 3 and the moving grinding disc 4 in the crushing cylinder 2, falls into the crushing box 8, it is guided by the feed plates 8-2 and falls between the two crushing rollers 9-1 to be further crushed into fine aggregate. The crushed aggregate falls through the gap between the two crushing rollers 9-1 onto the screening mechanism 10 for screening.

[0076] like Figure 3 As shown, the fixed grinding disc 3 is arranged in the middle of the feed hopper 1 and the first discharge port 2-1, and a material distribution plate 3-2 is provided at the upper end of the fixed grinding disc 3. After the material is put into the feed hopper 1, it can be diverted by the material distribution plate 3-2 so that the material falls on both sides of the fixed grinding disc 3.

[0077] like Figures 3 to 6 As shown, the arc-shaped gate mechanism 5 includes an arc-shaped baffle 5-1, which is closed below the first discharge port 2-1 to intercept the material above. One end of the arc-shaped baffle 5-1 is fixedly connected to several arc-shaped sliding rods 5-2, which are slidably disposed within an arc-shaped guide sleeve 5-3. The arc-shaped guide sleeve 5-3 is fixedly disposed on the outer wall of the crushing cylinder 2. One end of the arc-shaped sliding rod 5-2, after passing through the arc-shaped guide sleeve 5-3, is fixedly provided with a first connecting steel ring 5-4. A rotatable first connecting rod 5-5 is disposed within the first connecting steel ring 5-4. A rotatable sleeve 5-6 is fitted onto the first connecting rod 5-5. A sleeve groove 5-6-1 is provided on the sleeve 5-6, and a rotatably connected first connecting plate 5-7 is disposed on the sleeve groove 5-6-1. Specifically, steel rings are provided at both ends of the first connecting plate 5-7. One end of the steel ring is rotatably fitted onto the sleeve groove 5-6-1. The other end of the steel ring of the first connecting plate 5-7 is rotatably connected to the output end of the first telescopic component 5-8. The first telescopic component 5-8 is fixedly mounted on the outer wall of the crushing cylinder 2 by a frame. When the first telescopic component 5-8 is activated and its output end moves upward, it will pull the first connecting plate 5-7 upward, thereby pulling the arc-shaped sliding rod 5-2 and the arc-shaped baffle 5-1 to move upward in a circular motion, thus opening the first discharge port 2-1 to release the material. After unloading, the first telescopic component 5-8 is activated to move its output end downward. The arc-shaped baffle 5-1 will slide down again due to its own weight to cover the first discharge port 2-1.

[0078] In this embodiment, the arc-shaped guide sleeve 5-3 is a steel sleeve structure with a smooth inner wall, and the arc-shaped slide rod 5-2 can slide freely inside the arc-shaped guide sleeve 5-3.

[0079] In this embodiment, the arc-shaped baffle 5-1 is a thickened steel plate.

[0080] In this embodiment, the outer wall of the crushing cylinder 2 is provided with a slot through which the arc-shaped baffle 5-1 can slide.

[0081] like Figures 7 to 8 As shown, the transverse movement mechanism 6 includes a second telescopic member 6-1, which is fixedly mounted at both ends of the crushing cylinder 2. A pusher disc 6-2 is fixedly mounted at the output end of the second telescopic member 6-1, and the pusher disc 6-2 is connected to the fixed shaft disc 4-1 and the outer ring disc 4-3. A first sliding groove 6-2-1 is provided on the edge of the pusher disc 6-2, and a first slide rail 2-2 is provided on the inner wall of the crushing cylinder 2. Limit ends are provided at both ends of the first slide rail 2-2, and the first sliding groove 6-2-1 is slidably connected to the first slide rail 2-2. When the output end of the second telescopic member 6-1 extends, the pusher disc 6-2 pushes the moving grinding disc 4 to move towards the fixed grinding disc 3. It should be noted that the extension stroke of the output end of the second telescopic member 6-1 needs to be controlled to prevent the crushing teeth 4-4 from piercing the protrusion 3-1 and causing damage.

[0082] The rotary drive mechanism 7 includes a drive motor 7-1, which is mounted on a motor base 7-2. A second sliding groove 7-2-1 is provided at the bottom of the motor base 7-2. A side window 2-3 is provided on the side of the grinding cylinder 2, and a support plate 2-4 is fixedly mounted on the bottom edge of the side window 2-3. A second slide rail 2-4-1 is provided on the support plate 2-4, and the second sliding groove 7-2-1 and the second slide rail 2-4-1 are slidably connected. The motor base 7-2 is fixedly connected to the outer ring disk 4-3, and the drive motor 7-1 is driven by the rotating ring disk 4-2. Starting the drive motor 7-1 causes the rotating ring disk 4-2 to rotate, thus producing a grinding effect. Simultaneously, when the second telescopic member 6-1 pushes the outer ring disk 4-3 to move laterally, it also drives the entire rotary drive mechanism 7 to move laterally synchronously.

[0083] It should be noted that the appendix Figure 7 To facilitate the display of the transverse movement mechanism 6, the moving grinding disc 4 and the rotation drive mechanism 7 on the right side of the crushing cylinder 2 are not shown.

[0084] like Figures 9 to 12 As shown, the fixed-axis disk 4-1 includes a fixed-axis disk body 4-1-1, and a first annular groove 4-1-3 is provided on the circumferential surface of the fixed-axis disk body 4-1-1. The fixed-axis disk body 4-1-1 is fixedly connected to the fixed-axis disk shaft 4-1-2.

[0085] The rotating disk 4-2 includes a rotating disk body 4-2-1. An inner annular slide rail 4-2-4 and an outer annular slide rail 4-2-5 are fixedly arranged on the inner and outer circumferential surfaces of the rotating disk body 4-2-1. The inner annular slide rail 4-2-4 is slidably arranged in the first annular groove 4-1-3 by means of a bearing.

[0086] The rotating disc body 4-2-1 is fixedly connected to the rotating disc sleeve 4-2-2. The rotating disc sleeve 4-2-2 is movably sleeved on the outside of the fixed-axis disc shaft 4-1-2. A transmission wheel 4-2-3 is fixedly installed on the tube body of the rotating disc sleeve 4-2-2. The transmission wheel 4-2-3 is connected to the output end of the drive motor 7-1 via a transmission belt. The transmission belt is located inside the side window 2-3, and the transmission belt will not contact the crushing cylinder 2 when it moves. Thus, the drive motor 7-1 drives the transmission wheel 4-2-3, the rotating disc sleeve 4-2-2, and the rotating disc body 4-2-1 to rotate.

[0087] The outer ring disc 4-3 includes an outer ring disc body 4-3-1. The outer peripheral wall of the outer ring disc body 4-3-1 is in sealed sliding contact with the inner walls of the left and right sides of the crushing cylinder 2. A second annular groove 4-3-3 is provided on the inner circumferential surface of the outer ring disc body 4-3-1. The outer annular slide rail 4-2-5 is slidably disposed in the second annular groove 4-3-3 by means of a bearing.

[0088] The outer ring disc body 4-3-1 is fixedly connected to the outer ring disc top rod 4-3-2. In this embodiment, three outer ring disc top rods 4-3-2 are provided, and the three outer ring disc top rods 4-3-2 are evenly arranged on the outside of the rotating disc sleeve 4-2-2. The outer ring disc top rods 4-3-2 do not contact the rotating disc sleeve 4-2-2. One of the outer ring disc top rods 4-3-2 is fixedly connected to the motor base 7-2. It should be noted that in this embodiment, sufficient gaps are left between the outer ring disc top rods 4-3-2 to facilitate the normal operation of the transmission belt.

[0089] In this embodiment, the fixed-axis disc shaft 4-1-2, the rotating disc sleeve 4-2-2, and the outer ring disc push rod 4-3-2 have the same length. The ends of the fixed-axis disc shaft 4-1-2 and the outer ring disc push rod 4-3-2 are fixedly connected to the pushing disc 6-2 of the transverse mechanism 6, and the end of the rotating disc sleeve 4-2-2 and the end face of the pushing disc 6-2 are in sliding contact with each other through the thrust bearing.

[0090] In this embodiment, the crushing teeth 4-4 are fixedly disposed on the end faces of the fixed-axis disk body 4-1-1, the rotating disk body 4-2-1, and the outer ring disk body 4-3-1. Furthermore, each of the three end faces of the fixed-axis disk body 4-1-1, the rotating disk body 4-2-1, and the outer ring disk body 4-3-1 is provided with only one ring of crushing teeth 4-4.

[0091] like Figures 12 to 17As shown, a first movable tooth assembly 4-5 is provided on the side of the outer ring disk body 4-3-1 near the rotating ring disk body 4-2-1. The first movable tooth assembly 4-5 is arranged between the crushing teeth 4-4. A first movable tooth drive mechanism 4-6 is provided on the side of the rotating ring disk body 4-2-1 near the outer ring disk body 4-3-1. When the rotating ring disk body 4-2-1 rotates, the first movable tooth drive mechanism 4-6 pushes the first movable tooth assembly 4-5, causing the movable teeth 4-5-4 in the first movable tooth assembly 4-5 to move, thereby changing the gap between the movable teeth 4-5-4 and the adjacent crushing teeth 4-4. This allows the fragments clamped between the movable teeth 4-5-4 and the adjacent crushing teeth 4-4 to be pushed loose, avoiding the problem of large fragments getting stuck between the movable teeth 4-5-4 and the adjacent crushing teeth 4-4.

[0092] like Figures 14 to 15 As shown, the first movable tooth assembly 4-5 includes a movable tooth cavity 4-5-1 and movable teeth 4-5-4. The movable tooth cavity 4-5-1 is located on the side of the outer ring disc body 4-3-1 near the rotating ring disc body 4-2-1. A vertically arranged third sliding groove 4-5-2 is provided on the side of the movable tooth cavity 4-5-1 facing the fixed grinding disc 3. A vertically arranged auxiliary guide rail 4-5-3 is provided on the inner wall of the movable tooth cavity 4-5-1. An insertion port 4-5-8 is provided at the bottom of the movable tooth cavity 4-5-1.

[0093] The movable tooth 4-5-4 is fixedly connected to the movable block 4-5-6 via the vertical sliding plate 4-5-5, and the movable block 4-5-6 is provided with an auxiliary sliding groove 4-5-7 on its side wall. The movable block 4-5-6 is movably arranged inside the movable tooth cavity 4-5-1. The auxiliary slide groove 4-5-7 is slidably connected to the auxiliary guide rail 4-5-3. The vertical slide plate 4-5-5 is slidably connected inside the third slide groove 4-5-2. A second spring 4-5-9 is provided between the movable block 4-5-6 and the inner top wall of the movable tooth cavity 4-5-1. Specifically, the top end of the second spring 4-5-9 is fixedly connected to the inner top wall of the movable tooth cavity 4-5-1, and the bottom end of the second spring 4-5-9 is fixedly connected to the movable block 4-5-6. In the initial state (when the first movable tooth drive mechanism 4-6 and the first movable tooth assembly 4-5 are not in contact), the movable block 4-5-6 is located at the bottom of the movable tooth cavity 4-5-1, that is, the bottom surface of the movable block 4-5-6 is in contact with the inner bottom surface of the movable tooth cavity 4-5-1.

[0094] like Figure 16 As shown, the first movable tooth drive mechanism 4-6 includes a squeezing chamber 4-6-1 and a pushing block 4-6-3. The squeezing chamber 4-6-1 is located on the side of the rotating disc body 4-2-1 near the outer ring disc body 4-3-1. The top of the squeezing chamber 4-6-1 is provided with a sliding outlet 4-6-2.

[0095] The push block 4-6-3 is movably disposed within the extrusion chamber 4-6-1. A compressed first spring 4-6-4 is disposed between the push block 4-6-3 and the bottom wall of the extrusion chamber 4-6-1, and the elastic force of the first spring 4-6-4 is much greater than that of the second spring 4-5-9. A push rod 4-6-5 is fixedly disposed on the push block 4-6-3, and the push rod 4-6-5 is slidably disposed within the slide outlet 4-6-2. A rotatable steel ball 4-6-6 is embedded at the top of the push rod 4-6-5.

[0096] The inner wall of the outer ring disc 4-3-1 is also provided with a smooth slide 4-6-7, which slides and engages with the steel ball 4-6-6. Similarly, the insertion port 4-5-8 is also provided on the slide 4-6-7, meaning that the outlet 4-6-2 and the insertion port 4-5-8 are on concentric circular tracks. When the ring disc 4-2-1 rotates, the rotational trajectory of the steel ball 4-6-6 lies on the slide 4-6-7, at which time the steel ball 4-6-6 will slide or roll along the slide 4-6-7. When the slide outlet 4-6-2 aligns with the insertion port 4-5-8 (when the steel ball 4-6-6 moves to the insertion port 4-5-8), the steel ball 4-6-6 will pass through the insertion port 4-5-8 and then push (or impact) the movable block 4-5-6 a short distance upwards (the second spring 4-5-9 is compressed), causing the movable tooth 4-5-4 to move upwards, producing a "biting" action, thereby changing the gap between the movable tooth 4-5-4 and the adjacent breaking tooth 4-4. When the rotating disc body 4-2-1 continues to rotate, the steel ball 4-6-6 is subjected to rotational force, the first spring 4-6-4 is compressed, and the steel ball 4-6-6 rolls out of the insertion port 4-5-8. At this time, the steel ball 4-6-6 re-enters the slide 4-6-7, the second spring 4-5-9 resets, and the movable tooth 4-5-4 resets.

[0097] It should be noted that in this embodiment, the rotation speed of the drive motor 7-1 should not be too fast, so as to ensure that the steel ball 4-6-6 has enough time to enter the insertion port 4-5-8 and lift (or impact) the movable block 4-5-6.

[0098] In this embodiment, the edge of the insertion port 4-5-8 is inclined and has a smooth structure to facilitate the rolling in and out of the steel ball 4-6-6.

[0099] like Figure 17As shown, in this embodiment, a second movable gear assembly 4-7 is provided on the side of the rotating disk body 4-2-1 near the fixed-axis disk body 4-1-1, and a second movable gear drive mechanism 4-8 is provided on the side of the fixed-axis disk body 4-1-1 near the rotating disk body 4-2-1. The second movable gear assembly 4-7 has the same structure as the first movable gear assembly 4-5, and the second movable gear drive mechanism 4-8 has the same structure as the first movable gear drive mechanism 4-6. The cooperation relationship between the second movable gear assembly 4-7 and the second movable gear drive mechanism 4-8 is also exactly the same as the cooperation relationship between the first movable gear assembly 4-5 and the first movable gear drive mechanism 4-6.

[0100] Similarly, slides 4-6-7 are also provided on the inner wall of the rotating disc body 4-2-1.

[0101] like Figures 18 to 19 As shown, the coarse material outlet 11 includes a discharge chute 11-1, which is located on the side wall of the crushing chamber 8. A discharge guide plate 11-2 is provided below the discharge chute 11-1. A cover 11-6 is provided on the outside of the discharge chute 11-1. An outlet 11-3 is provided between the cover 11-6 and the discharge guide plate 11-2. A sealing plate 11-4 is slidably mounted on the cover 11-6. The sealing plate 11-4 is fixedly connected to the output end of the third telescopic member 11-5, which is mounted on the cover 11-6. When the output end of the third telescopic member 11-5 extends or retracts, it can drive the sealing plate 11-4 to move up and down, thereby closing or opening the outlet 11-3.

[0102] In one embodiment, the sealing plate 11-4 is slidably disposed on the cover 11-6. In this embodiment, the cover 11-6 is provided with a sealing plate slide rail 11-6-1, and the sealing plate 11-4 is provided with a sealing plate slide groove 11-4-1. The sealing plate slide groove 11-4-1 and the sealing plate slide rail 11-6-1 are slidably connected and cooperated.

[0103] like Figures 20 to 21 Combination Figure 2 As shown, the screening mechanism 10 includes a screen 10-1, one end of which is fixedly connected to the top end of a third spring 10-2, and the bottom end of the third spring 10-2 is fixedly connected to the discharge guide plate 11-2.

[0104] Three guide bars 10-3 are provided at the other end of the screen 10-1, and three guide grooves 8-1 are provided on the side wall of the crushing box 8. The guide bars 10-3 are slidably arranged in the guide grooves 8-1 in a corresponding manner.

[0105] One end of the guide rail 10-3 passes through the guide rail vertical groove 8-1 and is connected to it by the connecting rod frame 10-4. The connecting rod frame 10-4 is provided with a rotatable second connecting plate 10-5. The other end of the second connecting plate 10-5 is provided with a first docking ring 10-5-1. The first docking ring 10-5-1 is movably connected to the second docking ring 10-6 (the first docking ring 10-5-1 and the second docking ring 10-6 are fastened together). The second docking ring 10-6 is fixedly set on the output end of the fourth telescopic member 10-7. The fourth telescopic member 10-7 is set on the side wall of the crushing box 8. When the output end of the fourth telescopic component 10-7 is activated to extend or retract, the connecting rod 10-4 and the screen 10-1 can be pulled to vibrate up and down, thereby achieving a screening effect. Materials smaller than the mesh size of the screen 10-1 will fall directly to the bottom and flow out from the fine material outlet 12, while materials larger than the mesh size of the screen 10-1 will flow out through the discharge chute 11-1, the discharge guide plate 11-2, and the outlet 11-3.

[0106] In this embodiment, the first telescopic component 5-8, the second telescopic component 6-1, the third telescopic component 11-5, and the fourth telescopic component 10-7 are cylinders.

[0107] The operation process of this invention is as follows:

[0108] First, the material to be processed (waste concrete blocks) is fed into the feed hopper 1. The material will fall between the fixed grinding disc 3 and the moving grinding disc 4 (at this time, the arc gate mechanism 5 is in a closed state). The second telescopic component 6-1 is activated to extend the output end, pushing the moving grinding disc 4 to move laterally as a whole. At this time, the fixed-axis disc body 4-1-1, the rotating disc body 4-2-1, the outer ring disc body 4-3-1 and the fixed grinding disc 3 will clamp the material in the middle and crush it. Then, the drive motor 7-1 is activated to drive the rotating disc body 4-2-1 to rotate, thereby producing a grinding effect and enhancing the crushing effect.

[0109] Meanwhile, during the rotation, the spacing between the crushing teeth 4-4 on the rotating disc 4-2-1 and the crushing teeth 4-4 on the fixed-axis disc 4-1-1 and the outer ring disc 4-3-1 changes, which also produces a grinding and biting effect. This can push and loosen the fragments clamped between adjacent crushing teeth 4-4, avoiding the problem of large fragments getting stuck between adjacent crushing teeth 4-4. Similarly, during the rotation, the first movable tooth drive mechanism 4-6 will also push the first movable tooth assembly 4-5, causing the movable teeth 4-5-4 in the first movable tooth assembly 4-5 to move, thereby changing the gap between the movable teeth 4-5-4 and the adjacent crushing teeth 4-4. This can push and loosen the fragments clamped between the movable teeth 4-5-4 and the adjacent crushing teeth 4-4, and also avoid the problem of large fragments getting stuck between the movable teeth 4-5-4 and the adjacent crushing teeth 4-4.

[0110] When the crushing operation reaches the predetermined time, the first telescopic component 5-8 is activated, the arc-shaped baffle 5-1 is pulled up, and the first discharge port 2-1 is opened. The crushed material falls into the crushing box 8 and is further crushed by the crushing roller 9-1 before falling onto the screen 10-1. The fourth telescopic component 10-7 is activated to reciprocate to extend and retract, which will cause the screen 10-1 to vibrate up and down. Material smaller than the mesh size of the screen 10-1 will fall directly to the bottom and flow out from the fine material outlet 12. Material larger than the mesh size of the screen 10-1 will flow out through the discharge chute 11-1, the discharge guide plate 11-2, and the outlet 11-3 and enter the next process.

[0111] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
