Description

Technical Field

[0001] The present application relates to the field of concrete recycling, and in particular to an ultrasonic slag removal device for recycled aggregates. Background Art

[0002] With the rapid development of the construction industry, construction waste is increasing, which puts tremendous pressure on the environment. Recycled aggregates, i.e. concrete blocks, gravel, etc. recovered from construction waste, can be reused as new building materials after proper treatment. However, these aggregates are often mixed with impurities such as soil, steel bar residues, and sawdust, which affects their reuse value. Recycled aggregates are rinsed with a high-pressure water gun or with running water in a cleaning pool to remove mud, dust and other loose impurities on the surface of the aggregates. The water washing method is simple to operate, but it consumes a lot of water and may cause secondary pollution. Therefore, it is urgent to develop an efficient and environmentally friendly recycled aggregate slag removal device. Utility Model Content

[0029] The present application discloses an ultrasonic slag removal device for recycled aggregate. Figure 1, including a feeding mechanism 1 for conveying materials to be cleaned, a cleaning mechanism 2 for cleaning materials, and a discharging mechanism 3 for conveying cleaned materials.

[0030] Reference Figure 1 and Figure 2 The cleaning mechanism 2 includes a support frame 21 and a cleaning pool 22 fixedly connected to the support frame 21. The cleaning pool 22 is in the shape of a rectangular parallelepiped, and the hollow opening inside the cleaning pool 22 faces upward. Ultrasonic oscillators 4 are installed on the inner side walls around the cleaning pool 22, and the cleaning pool 22 is filled with nano-scale silica solution. A slag receiving bucket 5 is fixedly connected to the outer bottom wall of the cleaning pool 22, and a plurality of filter holes 221 are provided on the inner bottom wall of the cleaning pool 22. The cleaning pool 22 is connected to the slag receiving bucket 5 through the filter holes 221. A drain pipe 6 for drainage is connected to the bottom wall of the cleaning pool 22, and a gate valve for controlling the opening and closing of the drain pipe 6 is installed on the drain pipe 6. The aggregate to be cleaned is fed into the cleaning pool 22 through the feeding mechanism 1, and the dust and debris remaining on the aggregate are removed by the ultrasonic oscillator 4, so as to achieve the effect of slag removal, which is efficient, saves water resources, and saves time and effort.

[0031] Reference Figure 1 and Figure 2 Four vibrators 7 are installed at intervals along the circumferential direction on the outer bottom wall of the cleaning tank 22. The vibrators 7 can provide vibration for the cleaning tank 22, thereby facilitating the removal of aggregate slag from the bottom of the cleaning tank 22; on the other hand, the broken slag and impurities can be shaken into the slag receiving bucket 5 through vibration. A vibration isolator is installed at the lower end of each support foot of the support frame 22, and the vibration isolator can reduce the transmission of vibration to the ground.

[0032] Reference Figure 1 and Figure 2 A plurality of crushing ridges 222 are fixedly connected in parallel on the inner bottom wall of the cleaning tank 22. When the aggregate moves in the cleaning tank 22, the aggregate collides with the crushing ridges 222, thereby accelerating the removal of the aggregate.

[0033] Reference Figure 1 and Figure 2 Two steel wire roller brushes 223 are rotatably connected between the two inner side walls facing each other of the cleaning pool 22, and two driving motors 224 for driving the steel wire roller brushes 223 to rotate are installed on the outer side wall of the cleaning pool 22, and the output shaft of the driving motor 224 is fixedly connected to one end of the steel wire roller brush 223. The steel wire roller brush 223 can stir the water flow in the cleaning pool 22, and at the same time, when the steel wire roller brush 223 contacts the aggregate, it can quickly remove the residue on the aggregate, thereby improving the efficiency of removing the aggregate.

[0034] Reference Figure 1 and Figure 2The feeding mechanism 1 includes a feeding frame 11 and a feeding conveyor belt 12 mounted on the feeding frame 11, and the feeding conveyor belt 12 is driven to rotate by a servo motor. The feeding frame 11 is fixedly connected with a baffle plate 111 on both sides of the feeding conveyor belt 12 in a vertical direction. The baffle plate 111 can prevent the material from falling off the feeding conveyor belt 12.

[0035] Reference Figure 1 and Figure 2 The discharging mechanism 3 includes a discharging frame 31 and a discharging conveyor belt 32 mounted on the discharging frame 31, and the discharging conveyor belt 32 is driven to rotate by a servo motor. The staff puts the aggregate after slag removal on the discharging conveyor belt 32, and the discharging conveyor belt 32 transports the aggregate to the designated stacking position.

[0036] Reference Figure 1 and Figure 2 The lower end surface of the slag hopper 5 is provided with a discharge port 51, and a sealing plate 52 is hingedly connected to the lower end surface of the slag hopper 5 for closing the discharge port 51. A sealing ring made of silicone material is fixedly connected to the side of the sealing plate 52 that is in close contact with the lower end surface of the slag hopper 5. The movable end of the sealing plate 52 is fixedly connected with a fixing bar 521, and the end of the fixing bar 521 away from the sealing plate 52 is rotatably connected with a fixing arm 522. A fixing column 53 is fixedly connected to the vertical outer wall of the slag hopper 5, and a fixing groove 5221 is provided at the movable end of the fixing arm 522 for the fixing column 53 to be inserted. When it is necessary to empty the debris and impurities in the slag hopper 5, the fixing arm 522 is rotated to disengage the fixing column 53 from the fixing groove 5221, and then the sealing plate 52 is rotated to pour the debris and impurities in the slag hopper 5 out of the discharge port 51, and then the slag hopper 5 is emptied, saving time and effort. One end of the fixing column 53 is threadedly connected with a fixing bolt 531 for pressing the fixing arm 522. After the fixing column 53 is inserted into the fixing groove 5221, the fixing bolt 531 is tightened so that the fixing bolt 531 presses the fixing arm 522, thereby preventing the fixing arm 522 from rotating accidentally.

[0037] The implementation principle of the ultrasonic slag removal device for recycled aggregate in the embodiment of the present application is: the aggregate to be cleaned is fed into the cleaning tank 22 through the feeding mechanism 1, and the dust and debris remaining on the aggregate are removed by the ultrasonic oscillator 4, so as to achieve the slag removal effect with high efficiency, saving water resources, time and labor.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
