Abstract
Description
Technical Field
[0001] The utility model relates to the field of aluminum material recovery, in particular to a flotation screening device, which is used for screening out impurities in the aluminum material. Background Art
[0002] like Figure 1 As shown, the flotation screening device in the prior art includes a base 1, which is a long strip extending horizontally from front to back. Figure 2 As shown, from this perspective, the base 1 is in the shape of a concave arc, with a front and rear horizontal power shaft 3 installed at the center of the arc, and a motor (not shown in the figure) that drives the power shaft 3 to rotate is installed on the base 1. A radial support rod 9 is installed on the power shaft 3; an inner cylinder 4 is provided outside the power shaft 3, and the inner cylinder 4 covers the power shaft 3 and the radial support rod 9, and the inner wall of the inner cylinder 4 is installed at the far end of the radial support rod 9. A plurality of screening holes (not shown in the figure) are provided on the wall of the inner cylinder 4. A circular outer cylinder 2 is provided outside the inner cylinder 4, and the circular outer cylinder 2 has the same axial position as the inner cylinder 4. The circular outer cylinder 2 is fixed on the base 1 and covers the inner cylinder 4, and the inner wall of the inner cylinder 4 does not contact the outer wall of the circular outer cylinder 2. The working process is as follows: the operator places aluminum material into the inner cylinder 4 and starts the motor. The motor drives the power shaft 3 to rotate, driving the inner cylinder 4 to rotate. Aluminum material with a particle size smaller than the sieve hole will be thrown out by the inner cylinder 4 through the sieve hole into the circular outer cylinder 2 and then recycled. However, debris 5 (such as screws and large sand and gravel) mixed with the aluminum material with a particle size not smaller than the sieve hole will be retained in the inner cylinder 4 and then cleared. The disadvantage of the existing technology is that some debris 5 will get stuck in the sieve hole, causing the sieve hole to be blocked. The operator needs to climb into the inner cylinder 4 to clear the blocked sieve hole, but the space inside the inner cylinder 4 is small and inconvenient for the operator to enter. Utility Model Content
[0003] The utility model aims to provide a flotation screening device which is convenient for clearing blockage, and an operator can clear blocked screening holes without having to climb into an inner cylinder.
[0004] The flotation screening device is convenient for clearing blockages, and includes a base. The base is a long strip extending transversely from front to back, with the left and right sides of the base being high and the middle being concave, thereby forming a concave arc. A power shaft extending transversely from front to back is installed at the center of the arc, and a motor for driving the power shaft to rotate is installed on the base; a radial support rod is installed on the power shaft; an inner cylinder is provided outside the power shaft, the inner cylinder covers the power shaft and the radial support rod, and the inner wall of the inner cylinder is installed at the far end of the radial support rod; a plurality of screening holes are opened on the wall of the inner cylinder; a circular outer cylinder is provided outside the inner cylinder, the circular outer cylinder and the inner cylinder have the same axial position, the circular outer cylinder is fixed on the base and covers the inner cylinder, and the inner wall of the inner cylinder does not contact the outer wall of the circular outer cylinder; the inner cylinder is a polygonal inner cylinder, and the cylinder wall is composed of a plurality of cylinder wall panels that are detachably assembled.
[0005] Furthermore, there are multiple radial support rods, and the distal end of each radial support rod is equipped with a front and rear transverse axial mounting rod; the cylindrical wall plate is provided between any two adjacent axial mounting rods, and the left and right sides of the bottom wall of each cylindrical wall plate are respectively detachably mounted on the corresponding two axial mounting rods.
[0006] Furthermore, the cylinder wall plate is in the shape of a long strip extending transversely from front to back, and its length is adapted to that of the inner cylinder.
[0007] Furthermore, there are eight radial support rods, and there are correspondingly eight long strip cylinder wall panels, and the polygonal inner cylinder is an octagonal inner cylinder.
[0008] Furthermore, the axial mounting rod is specifically welded to the distal end of the radial support rod.
[0009] Furthermore, two groups of through-type screw holes are provided on the axial mounting rod, and the two groups of through-type screw holes are staggered with each other so as to face the two long cylindrical wall plates installed on the axial mounting rod respectively. The two groups of bolts pass through the two groups of through-type screw holes respectively and then penetrate into the two long cylindrical wall plates respectively.
[0010] The beneficial effect is that when the operator needs to clean the clogged screening holes on the wall of the polygonal inner tube, he only needs to disassemble the tube wall plates one by one, and then move the disassembled tube wall plates out of the polygonal inner tube, and then he can clean the clogged screening holes on these tube wall plates, without having to crawl into the narrow space in the inner tube to clean as in the prior art.

[0017] The present invention will be further described in detail below in conjunction with specific implementation methods.
[0018] like Figure 3 and Figure 4 As shown, a flotation screening device that is convenient for clearing blockages includes a base 1. The base 1 is a long strip extending horizontally from front to back. The left and right sides of the base 1 are high, and the middle is concave, thus forming a concave arc. A power shaft 3 extending horizontally from front to back is installed at the center of the arc. A motor (not shown in the figure) that drives the power shaft 3 is installed on the base 1. Eight radial support rods 9 are installed on the rear end of the power shaft 3. The distal end of each radial support rod 9 is welded with a front and rear transverse axial mounting rod 8. The axial mounting rod 8 is provided with two sets of screw holes at staggered angles. Between any two adjacent axial mounting rods 8, there is a long strip of cylindrical wall plate 6 extending horizontally from front to back. There are eight pieces in total. Take two of them as an example. Figure 5 As shown, a first bolt 11 passes through a first set of screw holes and then into one elongated cylindrical wall plate 6. A second bolt 12 passes through a second set of screw holes and then into the other elongated cylindrical wall plate 6. These two elongated cylindrical wall plates 6 are thus removably mounted on the axial mounting rod 8, forming an octagonal inner cylinder 7. A circular outer cylinder 2 is disposed outside the octagonal inner cylinder 7, and its length matches that of the cylindrical wall plates 6. The circular outer cylinder 2 and the octagonal inner cylinder 7 have the same axial position. The circular outer cylinder 2 is fixed to the base 1 and encloses the octagonal inner cylinder 7. The inner wall of the octagonal inner cylinder 7 does not contact the outer wall of the circular outer cylinder 2.
[0019] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
