Description
Technical Field
[0001] This invention belongs to the technical field of recycling devices, and relates to a recycling device for construction concrete waste. Background Technology
[0002] Concrete is made by mixing cement as a binder and sand and gravel as aggregates in a specific ratio. It is widely used in construction projects. Concrete is typically mixed at a batching plant and then transported to a designated location by mixer trucks. After use, both the mixer trucks and the batching plant need to be rinsed, generating wastewater containing a significant amount of sand and gravel, which needs to be separated and recycled. Existing recycling devices often experience problems when separating sand and gravel from concrete waste. Sand and gravel easily clog the filter screens, making cleaning difficult, and sand tends to stick to the stones, resulting in poor separation efficiency. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a concrete waste recycling device for construction. This invention solves the problems of existing recycling devices where sand and gravel easily clog the filter screen during the separation of concrete waste, making it difficult to clean, and sand easily sticks to the stones, resulting in poor separation efficiency.
[0004] The objective of this invention can be achieved through the following technical solutions:
[0005] A concrete waste recycling device for construction is characterized by comprising a recycling bin, a first feed inlet at the upper end of the recycling bin, a first rotating rod and a second rotating rod rotatably connected inside the recycling bin, a first drive motor for driving the first rotating rod and a second drive motor for driving the second rotating rod on the recycling bin, a first filter screen symmetrically arranged on the first rotating rod and a second filter screen symmetrically arranged on the second rotating rod, the first filter screen being located below the first feed inlet and the second filter screen being located below the first filter screen, a stone collection box being located on the left side below the first filter screen, the stone collection box having several sand leakage holes at its lower end, a sand collection box being located on the left side below the second filter screen, the sand collection box having several water leakage holes at its lower end, a first push rod motor being fixedly connected to the right side of the recycling bin, a second push rod motor being located below the first push rod motor, and U-shaped frames corresponding to the first and second filter screens being fixedly connected to the push rods of the first and second push rod motors respectively, the openings of the U-shaped frames facing to the left, the length of the openings of the U-shaped frames being slightly greater than the heights of the first and second filter screens, and a wastewater pool being located at the bottom of the recycling bin.
[0006] In the aforementioned concrete waste recycling device, a second inlet is inclinedly connected to the first inlet. Two rotating crushing rollers are symmetrically arranged inside the second inlet, and a third drive motor is installed on the second inlet to drive the crushing rollers. For concrete waste that can be recycled but has solidified into lumps, it is poured into the second inlet, and the crushing rollers are driven by the third drive motor to crush it. After crushing, it enters the first inlet and is then sent to the recycling bin for separation and recycling.
[0007] In the aforementioned concrete waste recycling device, several inclined guide plates are staggered inside the first inlet. These inclined guide plates slow down the rate at which wastewater falls.
[0008] In the above-mentioned construction concrete waste recycling device, vibrating blocks are fixedly connected to both ends of the first and second filter screens, and the vibrating blocks are provided with a rubber layer.
[0009] In the above-mentioned construction concrete waste recycling device, a third push rod motor is fixedly connected to the left side of the recycling box, a cleaning frame is fixedly connected to the push rod of the third push rod motor, a cleaning steel brush is rotatably connected to the cleaning frame, and a fourth drive motor is provided on the cleaning frame to drive the cleaning steel brush to rotate.
[0010] In the above-mentioned concrete waste recycling device for construction, the stone collection box is slidably connected inside the recycling bin, and a fourth push rod motor is fixedly connected to the recycling bin. The push rod of the fourth push rod motor is connected to the stone collection box.
[0011] In the above-mentioned concrete waste recycling device for construction, a water spray pipe is provided above the first filter screen.
[0012] In the above-mentioned construction concrete waste recycling device, the lower end of the recycling box is fixedly connected to a support base, and the wastewater pool is equipped with a drain pipe.
[0013] Compared with the prior art, the present invention has the following advantages:
[0014] The first and second drive motors drive the first and second filter screens to rotate back and forth slightly, causing the right ends of the first and second filter screens to collide with the inside of the U-shaped frame. This shakes off the sand and gravel clogging the first and second filter screens on the left side, preventing them from affecting the subsequent separation effect. During the vibration, residual sand on the stones intercepted on the first filter screen on the right side is also shaken off, improving the sand and gravel separation effect. The sand and water remaining in the stone collection box can pass through the sand leakage hole and fall into the sand collection box, while the wastewater carried in the sand collection box can fall into the wastewater pool through the water leakage hole. The alternating use of the first and second filter screens on both sides makes the sand and gravel filtration more efficient and effective. At the same time, timely emptying of the sand and gravel prevents the filter screens from being damaged by excessive sand and gravel. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0020] like Figures 1 to 2 As shown,
[0021] A concrete waste recycling device for construction is characterized by comprising a recycling box 2, a first inlet 3 at the upper end of the recycling box 2, a first rotating rod 4 and a second rotating rod 5 rotatably connected inside the recycling box 2, a first drive motor 6 for driving the first rotating rod 4 and a second drive motor 7 for driving the second rotating rod 5 on the recycling box 2, a first filter screen 8 symmetrically arranged on the first rotating rod 4, and a second filter screen 9 symmetrically arranged on the second rotating rod 5, the first filter screen 8 being located below the first inlet 3 and the second filter screen 9 being located below the first filter screen 8, and a stone collection box 10 being located on the left side below the first filter screen 8. The collection box 10 has several sand leakage holes 11 at its lower end. A sand collection box 12 is located on the left side below the second filter screen 9. The sand collection box 12 has several water leakage holes 13 at its lower end. A first push rod motor 14 is fixedly connected to the right side of the recycling box 2. A second push rod motor 15 is located below the first push rod motor 14. U-shaped frames 16 corresponding to the first filter screen 8 and the second filter screen 9 are fixedly connected to the push rods of the first push rod motor 14 and the second push rod motor 15, respectively. The opening of the U-shaped frame 16 faces to the left. The opening length of the U-shaped frame 16 is slightly greater than the height of the first filter screen 8 and the second filter screen 9. A wastewater pool 17 is located at the bottom of the recycling box 2.
[0022] In this embodiment, the generated wastewater enters the recycling tank 2 through the first inlet 3 and falls onto the first filter screen 8 on the right side of the first rotating rod 4. The first filter screen 8 intercepts stones in the wastewater, while sand and wastewater pass through the first filter screen 8 and fall onto the second filter screen 9 on the right side of the second rotating rod 5 below. The second filter screen 9 intercepts sand, while wastewater passes through the second filter screen 9 and falls into the wastewater pool 17 below. After the first filter screen 8 and the second filter screen 9 on the right side have been used for a period of time, the amount of sand and gravel intercepted at their upper ends continues to increase. At this time, the first drive motor 6 and the second drive motor 7 are started, driving the first filter screen 8 and the second filter screen 9 to rotate half a turn, so that the stones on the first filter screen 8 fall into the stone collection box 10, and the sand on the second filter screen 9 falls into the sand collection box 12. At this time, the first filter screen 8 and the second filter screen 9, which were originally located on the left side, rotate to the right side to continue separating the sand and gravel in the wastewater. At the same time, the first push rod motor 14 and the second push rod motor 15 drive... The U-shaped frame 16 moves, allowing the right ends of the first filter screen 8 and the second filter screen 9 to enter the opening of the U-shaped frame 16. The first drive motor 6 and the second drive motor 7 drive the first filter screen 8 and the second filter screen 9 to rotate back and forth slightly, causing the right ends of the first filter screen 8 and the second filter screen 9 to collide back and forth with the inside of the U-shaped frame 16. This shakes off the sand and gravel clogging the first filter screen 8 and the second filter screen 9 on the left side, preventing them from affecting the subsequent separation effect. During the vibration, it can also shake off the sand remaining on the stones intercepted on the first filter screen 8 on the right side, improving the sand and gravel separation effect. The sand and water remaining in the stone collection box 10 can pass through the sand leakage hole 11 and fall into the sand collection box 12. The sewage carried in the sand collection box 12 can fall into the sewage pool through the water leakage hole 13. The alternating use of the first filter screen 8 and the second filter screen 9 on both sides makes the sand and gravel filtration more efficient and effective. At the same time, timely emptying of the sand and gravel will prevent the sand and gravel on the filter screen from being damaged by too much sand and gravel.
[0023] In this embodiment, a second feed inlet 18 is inclinedly provided on the first feed inlet 3 and communicates with it. Two rotating crushing rollers 19 are symmetrically arranged inside the second feed inlet 18, and a third drive motor 20 is provided on the second feed inlet 18 to drive the crushing rollers 19 to rotate. For some recyclable but solidified concrete waste, it is poured into the second feed inlet 18, and the crushing rollers 19 are driven by the third drive motor 20 to crush it. After crushing, it enters the first feed inlet 3 and is then sent to the recycling bin 2 for separation and recycling.
[0024] In this embodiment, a plurality of inclined guide plates 21 are staggered inside the first feed inlet 3. The presence of the plurality of inclined guide plates 21 slows down the speed at which the sewage falls.
[0025] In this embodiment, vibrating blocks 22 are fixedly connected to both ends of the first filter screen 8 and the second filter screen 9, and the vibrating blocks 22 are provided with a rubber layer 23. By colliding with the U-shaped frame 16, the sand and gravel stuck on the filter screen are shaken off, while reducing damage to the filter screen. The rubber layer 23 on the surface can significantly reduce noise.
[0026] In this embodiment, a third push rod motor 24 is fixedly connected to the left side of the recycling bin 2. A cleaning frame 25 is fixedly connected to the push rod of the third push rod motor 24. A cleaning steel brush 26 is rotatably connected to the cleaning frame 25. A fourth drive motor 27 is provided on the cleaning frame 25 to drive the cleaning steel brush 26 to rotate. When stones are poured out of the first filter screen 8 on the left side, the fourth drive motor 27 drives the cleaning steel brush 26 to rotate, and the third push rod motor 24 drives the cleaning frame 25 and the cleaning steel brush 26 to move back and forth, so that the cleaning steel brush 26 brushes the stones loosened at the lower end of the first filter screen 8 into the stone collection box 10 below.
[0027] In this embodiment, the stone collection box 10 is slidably connected inside the recycling bin 2. A fourth push rod motor 28 is fixedly connected to the recycling bin 2, and the push rod of the fourth push rod motor 28 is connected to the stone collection box 10. The fourth push rod motor 28 drives the stone collection box 10 to slide back and forth, causing the stones inside the stone collection box 10 to shake back and forth, shaking off the sand remaining on the stones, and letting it fall from the sand leakage hole 11 into the sand collection box 12 below, thus improving the separation effect of sand and stones.
[0028] In this embodiment, a water spray pipe 29 is provided above the first filter screen 8. The water spray pipe 29 sprays water onto the first filter screen 8, which helps to wash away the stones that are blocked on the first filter screen 8. After the water passes through the first filter screen 8, it falls into the stone collection box 10, which helps to wash away the sand remaining on the stones into the sand collection box 12 below, so that the separation effect of sand and stones is better.
[0029] In this embodiment, a support base 30 is fixedly connected to the lower end of the recycling bin 2, and a drain pipe 31 is provided on the wastewater pool 17. Wastewater in the wastewater pool 17 is discharged through the drain pipe 31.
