Description

Technical Field

[0001] This utility model relates to the field of aggregate strengthening, specifically a device for strengthening recycled concrete aggregates. Background Technology

[0002] Recycled concrete refers to new concrete made by crushing, washing, and grading concrete waste, then mixing it with other materials in a certain proportion to partially or completely replace natural materials such as sand and gravel. A crucial step is the strengthening treatment of the recycled concrete aggregates. This treatment typically involves two methods: physical strengthening and chemical strengthening. Physical strengthening can be achieved through mechanical grinding, where the recycled coarse aggregates collide and rub against each other to remove surface mortar, thereby improving their particle shape.

[0003] Existing recycled concrete aggregate grinding equipment has a low grinding capacity per cycle and uses a single grinding method, making it unsuitable for large-scale processing and resulting in low grinding efficiency for resource aggregates.

[0004] Therefore, a recycled concrete aggregate strengthening device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a recycled concrete aggregate strengthening device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A recycled concrete aggregate strengthening device of this utility model includes a base; a mixing tank is fixedly connected to the top of the base; a crushing box is provided on the top of the mixing tank; a crushing shaft is rotatably connected to the inner side of the crushing box; the bottom of the crushing box is connected to the mixing tank; a motor is fixedly connected to the top of the mixing tank; a grinding column is fixedly connected to the output end of the motor; the grinding column is rotatably connected to the mixing tank; a first grinding rod is fixedly connected to the inner side of the mixing tank; a second grinding rod is fixedly connected to the surface of the grinding column; a discharge hopper is slidably connected to the bottom of the base; and a sieve plate is slidably connected to the inner side of the discharge hopper. In this step, the concrete aggregate is first crushed by the crushing box and the crushing shaft, making the aggregate easier to grind. The second grinding rod is rotated by the grinding column, cooperating with the first grinding rod inside the mixing tank to rotate and squeeze the aggregate for grinding, achieving aggregate grinding strengthening. The aggregate is then screened by the sieve plate to remove old cement paste from the aggregate, increasing the quality of aggregate grinding and discharge.

[0007] Preferably, a first connecting block is fixedly connected to the bottom of the base, and a second connecting block is fixedly connected to the surface of the discharge hopper. The first connecting block is connected to the second connecting block by bolts. This step, through the setting of the first and second connecting blocks, facilitates the disassembly and assembly of the discharge hopper, allowing the internal screen plate to be removed and cleaned.

[0008] Preferably, a connecting rod is fixedly connected to the bottom of the grinding column, and a stirring plate is fixedly connected to the surface of the connecting rod. The bottom surface of the stirring plate is in contact with the sieve plate. This step drives the stirring plate to rotate on the top of the sieve plate, stirring the aggregate remaining on the top of the sieve plate, preventing the aggregate from clogging on the top of the sieve plate, and making it easier for it to fall through the sieve plate.

[0009] Preferably, a limiting hole is provided at the bottom of the connecting rod, and a support rod is fixedly connected to the top of the sieve plate, with the limiting hole and the support rod slidably connected; this step can support the bottom of the connecting rod through the support rod, increasing the stability of the connecting rod and the grinding column when they rotate.

[0010] Preferably, the support rod has a through hole inside and a beveled cut at the top; this step facilitates the movement of the support rod by pulling it through the through hole, making it easier to bring the screen plate out of the discharge hopper.

[0011] Preferably, a guide groove is provided at the top of the grinding column, and a guide plate is fixedly connected to the inner side of the crushing box; this step uses the guide plate to facilitate the entry of aggregates inside the crushing box into the mixing tank, preventing aggregates from remaining inside the crushing box.

[0012] The advantages of this utility model are:

[0013] 1. The recycled concrete aggregate strengthening equipment of this utility model can first crush the concrete aggregate through the crushing box and crushing shaft, making the aggregate easier to grind. The grinding column drives the second grinding rod to rotate, which works in conjunction with the first grinding rod inside the mixing tank to grind the aggregate by rotation and compression, thereby achieving aggregate grinding strengthening. The aggregate is then screened through the sieve plate to remove the old cement paste in the aggregate, thereby increasing the quality of aggregate grinding and output.

[0014] 2. The recycled concrete aggregate strengthening equipment of this utility model, through the setting of the first connecting block and the second connecting block, facilitates the disassembly and assembly of the discharge hopper, and allows the internal screen plate to be removed and cleaned.

Detailed Implementation

[0022] 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.

[0023] like Figures 1 to 5As shown, a recycled concrete aggregate strengthening device includes a base 1; a mixing tank 12 is fixedly connected to the top of the base 1, a crushing box 13 is provided on the top of the mixing tank 12, a crushing shaft 14 is rotatably connected to the inner side of the crushing box 13, the bottom of the crushing box 13 is connected to the mixing tank 12, a motor 15 is fixedly connected to the top of the mixing tank 12, a grinding column 16 is fixedly connected to the output end of the motor 15, the grinding column 16 is rotatably connected to the mixing tank 12, a first grinding rod 17 is fixedly connected to the inner side of the mixing tank 12, a second grinding rod 18 is fixedly connected to the surface of the grinding column 16, a discharge hopper 19 is slidably connected to the bottom of the base 1, and a screen plate 110 is slidably connected to the inner side of the discharge hopper 19; during operation, concrete aggregate is poured into the interior of the crushing box 13, and the concrete aggregate is crushed and mixed by the crushing shaft 14, with the concrete aggregate entering the mixing chamber through the bottom of the crushing box 13. Inside the tank 12, the motor 15 drives the grinding column 16 to rotate, which in turn drives the second grinding rod 18 to rotate. The second grinding rod 18, in conjunction with the first grinding rod 17, mixes and crushes the concrete aggregate inside the mixing tank 12. The concrete aggregate falls above the screen plate 110. Smaller concrete aggregate particles fall through the screen plate 110 and into the discharge hopper 19, while larger concrete aggregate particles remain above the screen plate 110. This step, through the crushing box 13 and the crushing shaft 14, allows the concrete aggregate to be crushed first, making it easier to grind. The grinding column 16 drives the second grinding rod 18 to rotate, which, in conjunction with the first grinding rod 17 inside the mixing tank 12, rotates and compresses the aggregate for grinding, thereby strengthening the aggregate grinding. The aggregate is then screened through the screen plate 110 to remove old cement paste from the aggregate, increasing the quality of aggregate grinding and discharge.

[0024] like Figures 1 to 3 As shown, a first connecting block 21 is fixedly connected to the bottom of the base 1, and a second connecting block 22 is fixedly connected to the surface of the discharge hopper 19. The first connecting block 21 is connected to the second connecting block 22 by bolts. During operation, when the discharge hopper 19 needs to be disassembled, rotate the bolts connecting the first connecting block 21 and the second connecting block 22 to separate it from the second connecting block 22. Then rotate the discharge hopper 19 to separate it from the first connecting block 21. When the first connecting block 21 is separated from the second connecting block 22, the discharge hopper 19 can be disassembled. 9. Disassemble the hopper 19. Then, remove the internal screen plate 110. When installing the discharge hopper 19, align the top of the discharge hopper 19 with the bottom of the mixing tank 12. Then, reverse the discharge hopper 19 so that it drives the second connecting block 22 to connect with the first connecting block 21. Then, rotate the bolts to reinforce the first connecting block 21 and the second connecting block 22. This step, through the first connecting block 21 and the second connecting block 22, facilitates the disassembly and assembly of the discharge hopper 19. The internal screen plate 110 can be removed and cleaned.

[0025] like Figures 2 to 5As shown, a connecting rod 31 is fixedly connected to the bottom of the grinding column 16, and a stirring plate 32 is fixedly connected to the surface of the connecting rod 31. The bottom surface of the stirring plate 32 is in contact with the sieve plate 110. During operation, when the grinding column 16 rotates, it drives the connecting rod 31 to rotate, which in turn drives the stirring plate 32 to rotate. The stirring plate 32 stirs the aggregate at the top of the sieve plate 110. This step stirs the aggregate remaining at the top of the sieve plate 110 by driving the stirring plate 32 to rotate, preventing the aggregate from clogging at the top of the sieve plate 110 and making it easier for the aggregate to fall through the sieve plate 110.

[0026] like Figures 2 to 5 As shown, a limiting hole 41 is provided at the bottom of the connecting rod 31, and a support rod 42 is fixedly connected to the top of the screen plate 110. The limiting hole 41 and the support rod 42 are slidably connected. During operation, the connecting rod 31 rotates on the surface of the support rod 42. When the discharge hopper 19 separates from the mixing tank 12, it drives the screen plate 110 to move. The screen plate 110 drives the support rod 42 to separate from the limiting hole 41. This step can support the bottom of the connecting rod 31 through the support rod 42, increasing the stability of the connecting rod 31 and the grinding column 16 when rotating.

[0027] like Figure 5 As shown, the support rod 42 has a through hole 51 inside and a beveled cut at the top. During operation, the support rod 42 can be moved by pulling through the through hole 51, and the support rod 42 can drive the screen plate 110 to move. This step is facilitated by the through hole 51 to move the support rod 42, so that the screen plate 110 can be easily brought out of the discharge hopper 19.

[0028] like Figure 2 As shown, a guide groove is provided on the top of the grinding column 16, and a guide plate 61 is fixedly connected to the inner side of the crushing box 13. During operation, concrete aggregate falls through the crushing shaft 14 and then moves to both sides through the guide plate 61. This step, through the guide plate 61, makes it easier for the aggregate inside the crushing box 13 to enter the interior of the mixing tank 12, preventing the aggregate from remaining inside the crushing box 13.

[0029] Working principle: Concrete aggregate is poured into the crushing box 13, where it is crushed and mixed by the crushing shaft 14. The concrete aggregate enters the mixing tank 12 through the bottom of the crushing box 13. The motor 15 drives the grinding column 16 to rotate, which in turn drives the second grinding rod 18 to rotate. The second grinding rod 18, in conjunction with the first grinding rod 17, mixes and crushes the concrete aggregate inside the mixing tank 12. The concrete aggregate falls above the screen plate 110. Smaller concrete aggregate particles fall through the screen plate 110 and into the discharge hopper 19, while larger particles remain above the screen plate 110. When the grinding column 16 rotates, it drives the connecting rod 31 to rotate, which in turn drives the mixing plate 32 to rotate. The mixing plate 32 mixes the aggregate at the top of the screen plate 110. When the discharge hopper 19 needs to be disassembled... Rotate the bolts connecting the first connecting block 21 and the second connecting block 22 to separate them from the second connecting block 22. Then rotate the discharge hopper 19 to separate it from the first connecting block 21. When the first connecting block 21 and the second connecting block 22 are separated, the discharge hopper 19 can be removed. Then the internal screen plate 110 can be taken out. When the discharge hopper 19 needs to be installed, align the top of the discharge hopper 19 with the bottom of the mixing tank 12. Then reverse the discharge hopper 19 so that it drives the second connecting block 22 to connect with the first connecting block 21. Then rotate the bolts to reinforce the first connecting block 21 and the second connecting block 22. When the discharge hopper 19 is separated from the mixing tank 12, it drives the screen plate 110 to move. The screen plate 110 drives the support rod 42 to separate from the limiting hole 41. The support rod 42 can be pulled through the through hole 51 to move, and the support rod 42 drives the screen plate 110 to move.
