Description

Technical Field

[0001] The utility model relates to the field of sand and mud filtering, in particular to a sand and mud filtering drum device. Background Art

[0002] The sand and gravel separator can separate the sand, stone and mud of concrete, which is convenient for the recycling and reuse of concrete. The existing sand and gravel separators mostly use drum separation. The drum device is a hollow cylinder with a number of holes on its outer surface. Concrete enters the drum device and rotates continuously through it. Fine sand passes through the holes and large stones remain in the drum device. However, its screening efficiency is low and it cannot completely separate the mud and sand and gravel.

[0003] Therefore, it is necessary to provide a sand and mud filter drum device to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a sand and mud filtering drum device, including a drum, a mud spiral guide plate is provided on the outside of the drum, a mud collecting box is fixedly connected to the right end of the outer wall of the drum, a spiral sand removing plate is fixedly connected to the inner wall of the drum, and a sand and gravel collection box is fixedly connected to the inner wall of the left end of the drum.

[0005] Preferably, a drum shaft and no less than two vertical drum support rods are transversely provided inside the drum, the drum support rods are fixedly connected to the drum shaft and the drum inner wall, and cross bars are evenly distributed transversely on the drum outer wall, and the outside of the cross bars is fixedly connected to the mud spiral guide vanes.

[0006] Preferably, a reinforcing rib is fixedly connected at a connection point between the roller support rod and the roller shaft.

[0007] Preferably, drum discs are welded to both left and right ends of the drum, the opening direction of the mud collecting box is consistent with the rotation direction of the mud spiral guide vane, and the right end tail of the mud spiral guide vane is welded and fixed to the mud collecting box.

[0008] Preferably, the opening direction of the sand and gravel collecting box is consistent with the rotation direction of the spiral sand-swiping piece, and the left end tail of the spiral sand-swiping piece is welded and fixed to the sand and gravel collecting box.

[0009] Preferably, a plurality of holes are evenly distributed on the drum.

[0010] Preferably, filter holes are provided at the bottom of the sand and gravel collection box.

[0011] Compared with the prior art, the utility model provides a sand and mud filter drum device having the following beneficial effects:

[0012] The utility model fixes two augers with opposite rotation directions inside and outside the drum. When the drum is working, after the mud, sand and gravel mixture enters the drum, the mud, sand and gravel mixture follows the internal augers to move continuously to the left. In this process, the mud flows out of the drum through the holes on the drum, while the sand and gravel remain in the drum and continue to move to the left. During the movement, the sand and gravel will continuously hit the drum to cause the mud remaining on the surface of the drum to fall down. The sand and gravel move to the leftmost end along with the augers inside the drum and fall into the sand and gravel collecting box. Finally, the sand and gravel are discharged from the leftmost end. The fallen mud moves to the right to the mud collecting box at the right end under the pushing action of the augers outside the drum and is then discharged, thereby realizing the separation of sand and gravel from mud.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0020] See also Figure 1 and Figure 2, the embodiment of the utility model provides a sand and mud filtering drum device, the outside of the drum 8 is provided with a mud spiral guide plate 5, the right end of the outer wall of the drum 8 is fixedly connected to a mud collecting box 9, the inner wall of the drum 8 is fixedly connected to a spiral sand-swiping plate 6, and the inner wall of the left end of the drum 8 is fixedly connected to a sand and gravel collecting box 3. A drum shaft 1 and no less than two vertical drum support rods 4 are transversely provided inside the drum 8, and the drum support rods 4 are fixedly connected to the drum shaft 1 and the inner wall of the drum 8. The outer wall of the drum 8 is evenly distributed with cross bars 10 in the transverse direction, and the outside of the cross bars 10 is fixedly connected to the mud spiral guide plate 5, and the connection between the drum support rod 4 and the drum shaft 1 is fixedly connected with a reinforcing rib 7.

[0021] Among them, the roller support rod 4 and the cross rod 10 provide support for the roller 8 to prevent the roller 8 from being deformed during movement. In addition, since the roller shaft 1 inside the roller 8 is fixedly connected to the roller 8 through the roller support rod 4, the roller support rod 4 drives the roller 8 to rotate while the roller shaft 1 rotates, and the reinforcing rib 7 improves the connection strength between the roller support rod 4 and the roller shaft 1 to prevent the roller shaft 1 and the roller support rod 4 from being disconnected when the roller 8 is working.

[0022] As attached Figure 1 To Attachment Figure 4 As shown, a drum disc 2 is welded to both ends of the drum 8, the opening direction of the mud collecting box 9 is consistent with the rotation direction of the mud spiral guide plate 5, the right end tail of the mud spiral guide plate 5 is welded and fixed to the mud collecting box 9, the opening direction of the sand and gravel collecting box 3 is consistent with the rotation direction of the spiral sand shifting plate 6, and the left end tail of the spiral sand shifting plate 6 is welded and fixed to the sand and gravel collecting box 3.

[0023] Among them, the mud is transported to the mud collecting box 9 by the mud spiral guide plate 5 and is discharged during the rotation of the drum 8. The sand and gravel in the drum 8 are introduced into the sand and gravel collecting box 3 through the spiral sand-moving plate 6, and the sand and gravel are transported from the drum to the outside of the drum. Finally, the sand and gravel and mud are output from both ends of the drum 8 without interfering with each other.

[0024] As attached Figure 1 To Attachment Figure 4 As shown, the drum 8 is evenly distributed with a plurality of holes, and the bottom of the sand and gravel collecting box 3 is provided with filter holes. Among them, the bottom of the sand and gravel collecting box 3 is provided with evenly distributed round holes so that part of the waste in the sand and gravel can flow out again, and the mud collecting box 9 prevents the mud from leaking out, and the mud is discharged more cleanly.

[0025] During operation, since the spiral sand-prying pieces 6 inside the drum 8 rotate in opposite directions to the mud spiral guide pieces 5 outside the drum 8, after the mud and gravel mixture enters the rotating drum, the spiral sand-prying pieces 6 push the sand and gravel to the left, and the mud spiral guide pieces 5 push the mud flowing out of the drum to the right. The mud pushed to the right enters the mud collecting box 9 and is discharged during the rotation process, and the sand and gravel pushed to the left enters the sand and gravel collecting box 3 and is discharged during the rotation process, thereby separating the mud and gravel mixture.

[0026] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
