Description

Technical Field

[0001] The utility model relates to the technical field of concrete truck tail material recovery and separation, in particular to a concrete truck tail material recovery and separation device. Background Art

[0002] When a concrete truck delivers concrete, there will be some left over. The remaining concrete tailings will be handed over to the concrete production company, which will recycle the tailings in the concrete truck. The recycled tailings will be used for the subsequent production of concrete bricks, thereby saving materials and creating more value.

[0003] When a concrete truck is recycling tailings, it needs to use a large amount of water to dilute the concrete in the truck to facilitate the extraction of the diluted concrete from the truck, and then the tailings are recycled and separated. Traditional separation devices usually use filter plates to separate the sand and gravel in the tailings. Since concrete contains a lot of fine mud and sand, after a certain period of separation, the mud and sand and gravel are likely to clog the filter plates, making the subsequent separation rate slower, affecting the filtration and separation effect, and reducing the recycling rate.

One clearing member 107 is movably connected to one of the sieve holes 2.

[0032] The working principle of the present invention is as follows: in actual production and use, when it is necessary to recycle and separate the tailings, the tailings are put into the screening drum 7 from one end of the screening drum 7, and the rotary drive assembly is operated at the same time, so that the rotary drive assembly drives the screening drum 7 to rotate, and then the moisture and fine sand and mud in the tailings pass through the screening drum 7, and are discharged from the outside of the device through the sieve holes 2, and then the large particles of sand and gravel are retained in the screening drum 7. When the screening drum 7 rotates, the sand and gravel in the screening drum 7 slide to the other end of the screening drum 7 and are discharged from the outside of the device for collection. When the sieve holes 2 need to be cleared, the rotation can be stopped first. Screen the cylinder 7, then operate the first lifting assembly, so that the first lifting assembly drives the blowing assembly to descend, and then the blowing assembly fits the outer surface of the screen cylinder 7, and operates the blowing assembly, so that the blowing assembly blows the sieve holes 2, so that the sediment in the sieve holes 2 is blown into the interior of the screen cylinder 7, and the first linear drive member 103 can be operated, so that the first linear drive drives the dredging member 107 to descend through the mounting plate 109, so that the dredging member 107 dredges the sieve holes 2.

[0034] From the above description, it can be seen that when the sieve hole 2 needs to be unblocked, the blowing part 102 can be operated so that the wind generated by the blowing part 102 enters the inside of the blowing cover 104 through the air inlet pipe 101 and sprays the sieve hole 2, so that the mud and sand blocking the sieve hole 2 can be better unblocked.

[0035] Furthermore, the first lifting assembly includes a second linear drive member 106 and a second slider 105, and a second slider 105 is provided at both ends of the blowing hood 104.

When the tailings pass through the screening cylinder 7, the wastewater and fine sediment are discharged from the outside of the device through the sieve hole 2, and the separated sand and gravel are discharged from the device through the other end of the screening cylinder 7 for collection.

[0039] Furthermore, it also includes a dirt collecting box 9, which is provided below the screening drum 7. The dirt collecting box 9 is connected to the lower part of the frame 10, and a sewage outlet 8 is provided at the lower part of the dirt collecting box 9.
