Description

Technical Field

[0001] The utility model relates to the recycling of concrete waste residue, in particular to a concrete waste residue recycling system. Background Art

[0002] Waste residues in concrete production are generally divided into the following categories: slurry waste, which is mainly the "mixed liquid" produced by cleaning the drum of concrete transport vehicles and mixers, which contains "diluted" concrete components; block waste, which mainly comes from concrete test blocks in the laboratory and concrete blocks removed from concrete transport vehicles, mixers and production sites (such as the ground). These hardened concretes have a certain strength; concrete mixtures, which mainly come from the remaining concrete mixtures returned from pouring at the construction site and the concrete mixtures returned due to unqualified slump. However, for block waste, when it needs to be recycled, the crusher in the concrete waste recycling system is first used to crush the block waste.

[0003] For example, the application number is CN202220013561.5. The utility model discloses a concrete waste slag recovery device, which relates to the field of concrete processing technology, including a casing, wherein the inner cavity of the casing is symmetrically provided with crushing rollers, a frame is installed below the crushing rollers, a screen is welded to the bottom of the inner inner side of the frame, a metal plate is symmetrically welded to the bottom of the frame, an eccentric wheel is symmetrically installed below the metal plate, a transmission shaft is fixedly connected to the side wall of the eccentric wheel, and a roller is rotatably connected to the top of the eccentric wheel. The utility model screens and crushes large pieces of concrete after solidification and discharges them from the inside of the casing. During transportation, the utilization rate of the transportation space can be improved, thereby reducing the transportation cost.

[0004] Based on the search of the above patents and in combination with the devices in the prior art, it is found that the above device rotates the eccentric wheel to drive the screen to screen the crushed concrete. However, a large amount of dust will be generated during the screening process of concrete, thereby causing dust pollution, which is not conducive to the health of the workers. Utility Model Content

The rotation of the driving shaft and the rotating shaft drives the crushing wheel 1 and the crushing wheel 2 to crush the concrete waste.

[0018] 3. The rotation of the rotating shaft causes the transmission wheel 1 to rotate accordingly, and under the action of the belt, the transmission wheel 2 rotates synchronously with the transmission wheel 1. The rotation of the transmission wheel 2 causes the rotating rod to rotate in the box body, and the cam rotates synchronously with the rotating rod. Under the action of the spring elasticity, the screen plate is always in contact with the cam. The rotation of the cam and the mutual cooperation of the spring cause the screen plate to slide back and forth in the fixed groove, thereby screening the crushed waste residue. The screened waste residue flows to the discharge port through the guide block, which is convenient for the staff to collect the screened waste residue in a centralized manner for subsequent use. The waste residue that does not meet the size of the screen plate is intercepted by the screen plate, and the staff takes the intercepted waste residue out of the box body through the box door for re-crushing.

[0034] Embodiment three;

[0035] See also Figure 1 and Figure 4-Figure 6A dust removal device is provided between the screening device and the crushing device. The dust removal device includes a square tube 19 embedded in the inner surface of the box body 1. Dust suction ports 20 are equidistantly provided on the inner surface of the square tube 19. A first filter plate 21 is provided on the dust suction port 20. The first filter plate 21 is fixedly connected to the square tube 19. A dust collector 23 is fixedly connected to one end of the outer surface of the box body 1. The dust collector 23 is electrically connected to the controller and the required power is provided by the power supply. The dust collector 23 is connected to the square tube 19 through a connecting pipe 22. A dust removal box 25 is welded on the end of the outer surface of the box body 1 away from the dust collector 23. A box cover 26 is threadedly connected to the bottom end of the dust removal box 25. The bottom of one end of the outer surface of the dust removal box 25 is connected to the dust collector 23 through an air inlet pipe 24. A second filter plate 27 is welded inside the dust removal box 25. An exhaust port 26 is welded on the top of the dust removal box 25. The air pipe 28 and the exhaust pipe 28 are interconnected with the dust removal box 25, and the vacuum cleaner 23 starts to work, so that the dust inside the box body 1 enters the square tube 19 through the dust suction port 20. The setting of the first filter plate 21 prevents larger particles of waste from entering the square tube 19 under the action of suction, thereby blocking the square tube 19. The dust in the square tube 19 is transported to the air inlet pipe 24 through the connecting pipe 22, and under the action of the vacuum cleaner 23, the dust enters the dust removal box 25, and the second filter plate 27 in the dust removal box 25 filters the dust. The dust intercepted by the second filter plate 27 is at the bottom of the dust removal box 25, and the intercepted dust is collected by twisting the box cover 26. However, the filtered dust-free gas is discharged from the dust removal box 25 through the exhaust pipe 28, reducing dust pollution and thus ensuring the health of the staff.

[0036] In actual application, firstly, by placing concrete waste in the feed hopper 2 and making the driving motor 3 work, the driving motor 3 drives the driving shaft 4 to rotate in the box body 1, and at the same time, the driving gear 6 rotates synchronously with the driving shaft 4, and the driving gear 6 is meshed with the rotating gear 9, so that the rotating shaft 7 rotates in the opposite direction in the box body 1, and the rotation of the driving shaft 4 and the rotating shaft 7 drives the crushing wheel 1 5 and the crushing wheel 2 8 to crush the concrete waste. Secondly, the rotation of the rotating shaft 7 causes the transmission wheel 10 to rotate accordingly, and under the action of the belt 11, the transmission wheel 2 13 rotates synchronously with the transmission wheel 10. The rotation of the transmission wheel 2 13 causes the rotating rod 12 to rotate in the box body 1, and the cam 14 rotates synchronously with the rotating rod 12. Under the elastic action of the spring 18, the screen plate 16 is always in contact with the cam 14. The rotation of the cam 14 and the mutual cooperation of the spring 18 cause the screen plate 16 to slide back and forth in the fixed groove 15, so that the crushed waste is screened. Then, during the screening process, the dust collector 23 starts to work, so that the dust inside the box body 1 enters the square tube 19 through the dust suction port 20, and the dust in the square tube 19 is transported to the air inlet pipe 24 through the connecting pipe 22, and under the action of the dust collector 23, the dust enters the dust box 25, and the second filter plate 27 in the dust box 25 filters the dust. The dust intercepted by the second filter plate 27 is at the bottom of the dust box 25, and the intercepted dust is collected by twisting the box cover 26. However, the dust-free gas after filtering is discharged out of the dust box 25 through the exhaust pipe 28, reducing the dust pollution, thereby ensuring the health of the staff. The screened waste residue flows to the discharge port 30 through the guide block 29, which is convenient for the staff to collect the screened waste residue in a centralized manner for subsequent use. The waste residue that does not meet the size of the sieve plate 16 is intercepted by the sieve plate 16. The staff opens the box door 32 by the handle, takes the intercepted waste residue out of the box body 1, and crushes it again.
