Description

Technical Field

[0001] The invention relates to the technical field of recycled aggregate processing, and in particular to a recycled aggregate recovery device for construction waste. Background Art

[0002] Recycled aggregate is aggregate prepared from waste concrete. Since the surface of recycled aggregate is often covered with a layer of hardened old cement slurry, and the strength of this layer of old cement slurry is often low, which significantly affects the strength and durability of concrete, it is necessary to treat the surface of the recycled aggregate. The surface slurry is removed through the friction between the recycled aggregate and itself or the outside world, so as to achieve the purpose of shaping. In addition, the recycled construction waste also contains impurities such as plastic bag waste. During the shaping process of the recycled aggregate colliding with each other, the impurities need to be treated first. In the process, small fragments and dust will fall out together with the slurry. Directly disposing of the slurry mixed with aggregate fragments is also likely to cause waste of resources. Therefore, it is necessary to design a construction waste recycled aggregate recycling device that can quickly separate impurities from aggregate and conveniently treat fragments and dust. Summary of the invention

[0033] When it is necessary to process and recycle the recycled aggregates from the construction waste, the staff starts the second motor 93, and the second motor 93 drives the friction roller 92 to rotate through the second shaft 91. Due to the mutual meshing of the racks, the two friction rollers 92 rotate in opposite directions to rub against the recycled aggregates in the construction waste to remove the floating slurry on the surface. At the same time, the high-pressure water pump 122 is started, and the high-pressure water pump 122 pumps the high-pressure water into the circulating water pipe 124 through the main water pipe 125, and then flows back to the barrel body 121 through the circulating water pipe 124. When the second shaft 91 rotates, the second shaft 91 drives the top rod 131 to When the push rod 131 on one side rotates and squeezes the groove at the bottom of the top frame 136, the top frame 136 drives the circular frame 135 to move downward, the elastic member 134 is compressed, the circular frame 135 drives the circular frame 137 to move downward, the circular frame 137 squeezes the valve 128 handle, the torsion spring 129 is deformed, and then drives the valve 128 to rotate, and the water flows out through the three-way pipe 126 and the nozzle 127, thereby flushing the floating slurry on the recycled aggregate. When the push rod 131 on one side is separated from the groove at the bottom of the top frame 136, the elastic member 134 drives the circular frame 135 and the circular frame 137 to reset. , the torsion spring 129 drives the valve 128 to close, and when the other push rod 131 rotates and squeezes the groove at the bottom of the top frame 136 again, it can be flushed again. Through the cooperation of the two push rods 131, the nozzle 127 can intermittently spray water columns to flush the recycled aggregate, while preventing excessive water flow from causing subsequent separation difficulties. When the friction roller 92 rubs against the recycled aggregate and drives it to rotate downward and fall onto the screening component 6, the first motor 65 is controlled to work, and the first motor 65 drives the first rotating shaft 61 to rotate, which is transmitted through the pulley 63 and the flat belt 64, and then drives the screening roller 62 synchronously. Transmission to the right, by controlling the operation of the hot air blower 172, the hot air blower 172 blows the hot air into the processing box 5 through the pipe 173 and the guide air duct 171, dries the recycled aggregate stained with water, and blows the light impurities to the rear side through the discharge hopper 174 and falls into the collection net frame 20, the broken pieces and dust fall into the conveyor belt of the transmission component 15 through the gap between the screening rollers 62, and then transmit to the left side through the guide hopper 16 and flow into the placed collection frame, the recycled aggregate is transmitted to the right through the screening components 6 of the two processing boxes 5 through the lower hopper 14 and falls into the placed collection frame. There is a height difference between the screening components 6 of the two processing boxes 5, and then the falling can vibrate the recycled aggregate, further completing the separation of the broken pieces and dust. The device can quickly complete the processing of the recycled aggregate in the construction waste, and it is also convenient to collect the separated broken pieces and dust, which is beneficial to the subsequent recycling.

The left and right side walls of the guide air duct 171 are symmetrically rotatably provided with the third shaft 181, and the swinging blade 182 is provided on the third shaft 181. The left and right ends of the third shaft 181 are provided with cranks 183, and the two on the same side are provided with cranks 183. The other end of the crank 183 is rotatably connected to the lower side of the connecting rod 184, a connecting column 185 is arranged between the upper ends of the two connecting rods 184, a second guide sleeve 186 is symmetrically arranged on the front side wall of the guide air duct 171, and a moving rod 187 is slidably arranged in the second guide sleeve 186. A square card frame 188 is arranged on the top of the moving rod 187, and the square card frame 188 is sleeved with the connecting column 185. A connecting rod 189 is arranged between the bottoms of the two moving rods 187, and a cam 1810 capable of cooperating with the connecting rod 189 is arranged at the front end of the first rotating shaft 61.

[0035] When the first rotating shaft 61 rotates, it can drive the cam 1810 to rotate, and the cam 1810 squeezes the connecting rod 189. The connecting rod 189 drives the square card frame 188 to move upward through the moving rod 187, and the square card frame 188 drives the connecting column 185 to move upward. The connecting column 185 drives the crank 183 to swing through the connecting rod 184, and the crank 183 drives the third rotating shaft 181 to rotate, and then the swinging blade 182 swings. When the cam 1810 does not squeeze the connecting rod 189, the connecting rod 189 is reset under the action of gravity, and then the square card frame 188 drives the connecting column 185 to move downward and reset, and finally the swinging blade 182 is also reset. Through the continuous squeezing of the connecting rod 189 by the cam 1810, the swinging blade 182 is finally realized. Continuous up and down swinging of the swinging blade 182 is finally achieved, which is conducive to the uniform blowing of hot air to dry the recycled aggregate on the screening roller 62. The protective net cover can prevent impurities from falling into the guide air duct 171.
