Abstract
Description
Technical Field
[0001] The utility model relates to the field of aluminum powder recovery, in particular to a dry sieve for aluminum powder recovery. Background Art
[0002] During the aluminum powder recovery process, a dry sieve for aluminum powder recovery is required to sieve out impurities mixed in the aluminum powder. The existing dry sieve for aluminum powder recovery is as Figure 3 shown, including a first support column 6 placed on the ground. A spring 7 is installed on the top wall of the first support column 6, and a dry sieve body 3 is installed on the spring 7. A motor (not shown in the figure) is installed on the dry sieve body 3. A feeding trough (not shown in the figure) is provided above the dry sieve body 3, and a feeding port is opened on the bottom wall of the feeding trough. An outlet 9 is opened on the bottom wall of the dry sieve body 3. A blanking hopper 10 is provided directly below the outlet 9, and a receiving box 11 is provided directly below the blanking hopper 10. The feeding trough sends the aluminum powder to the dry sieve body 3 through the feeding port. The dry sieve body 3 is driven by the motor to vibrate, so as to sieve the aluminum powder onto the blanking hopper 10. The aluminum powder on the blanking hopper 10 falls into the receiving box 11 for recovery; while the impurities mixed in the aluminum powder have larger particle sizes, so they will not be sieved off by the dry sieve body 3, but are separated from the aluminum powder by the dry sieve body 3. The spring 7 buffers the vibrating dry sieve body 3. The defect of the prior art is that the vibration noise of the dry sieve body 3 is relatively large. Content of the Utility Model
[0003] The utility model aims to provide a dry sieve for aluminum powder recovery with low noise.
[0004] The dry sieve for aluminum powder recovery with low noise includes a first support column placed on the ground. A spring is installed on the top wall of the first support column, and a dry sieve body is installed on the spring. A motor is installed on the dry sieve body and drives it. A feeding trough for feeding the dry sieve body is provided above the dry sieve body; an outlet is opened on the bottom wall of the dry sieve body. A blanking hopper is provided directly below the outlet, and a receiving box is provided directly below the blanking hopper. It is characterized in that: it includes a sound insulation cover covering the outer top wall and the outer side wall of the dry sieve body, and a first sound insulation cotton pad is pasted on the inner side wall of the sound insulation cover; a vertical sound insulation curtain is installed on the bottom wall of the sound insulation cover.
[0005] Furthermore, vertical connecting strips are installed on the bottom wall of the sound insulation cover near the outer peripheral edge. A horizontal limiting strip is installed on the bottom wall of the connecting strip, and the limiting strip is located outside the sound insulation curtain to block the outer side wall of the sound insulation curtain.
[0006] Furthermore, a feeding trough is provided above the dry sieve body. A feeding port is opened on the bottom wall of the feeding trough, and the feeding trough feeds the dry sieve body through the feeding port; an opening is provided at the top of the side wall of the sound insulation cover, and the feeding trough passes through the opening to the outside of the sound insulation cover.
[0007] Further, a second support column is provided between the outer side wall of the dry screening machine body and the inner side wall of the sound insulation cover. The second support column is placed on the ground, and the inner top wall of the sound insulation cover is installed on the top wall of the second support column; a second sound insulation cotton pad is installed on the lower part of the side wall of the second support column.
[0008] Further, the height position of the second sound insulation cotton pad is the same as that of the sound insulation curtain.
[0009] The beneficial effects are as follows: The dry screening machine body vibrates under the drive of the motor to generate noise. The first sound insulation cotton pad, the sound insulation curtain and the ground on the inner side wall of the sound insulation cover jointly enclose the dry screening machine body in all directions to block the noise. After the noise breaks through the block and overflows to the outside world, it will be weakened into low noise. The sound insulation curtain is made of soft material, and the operator can push aside the sound insulation curtain and enter the sound insulation cover to inspect and maintain the dry screening machine body.

Detailed Embodiments
[0014] The following further elaborates on the present utility model in detail in combination with specific embodiments.
[0015] As Figure 2As shown in the figure, the low-noise aluminum powder recovery dry sieve machine of the present utility model includes four first support columns 6 (two of which are blocked by the other two), each first support column 6 is placed on the ground, and a spring 7 is installed on the top wall of each first support column 6. It includes a dry sieve machine body 3, the four corners of the bottom wall of which are respectively installed on the four springs 7. A motor (not shown in the figure) is installed on the dry sieve machine body 3 and drives it to vibrate. A feeding trough is arranged above the dry sieve machine body 3, and a feeding port is opened on the bottom wall of the feeding trough; a discharge port 9 is opened on the bottom wall of the dry sieve machine body 3, a blanking hopper 10 is arranged directly below the discharge port 9, and a receiving box 11 is arranged directly below the blanking hopper 10. The feeding trough sends the aluminum powder to the dry sieve machine body 3 through the feeding port. The dry sieve machine body 3 is driven by the motor to vibrate, so as to screen the aluminum powder onto the blanking hopper 10. The aluminum powder on the blanking hopper 10 falls into the receiving box 11 for recycling; the impurities mixed in the aluminum powder have a larger particle size, so they will not be screened out by the dry sieve machine body 3, but are separated from the aluminum powder by the dry sieve machine body 3. The spring 7 buffers the dry sieve machine body 3 when it vibrates.
[0016] There are two left second support columns 12 (one of which is blocked by the other) on the left side of the two left first support columns 6 (one of which is blocked by the other), and there are two right second support columns 12 (one of which is blocked by the other) on the right side of the two right first support columns 6 (one of which is blocked by the other). A cross beam 4 is installed on the top walls of these four second support columns 12, and four connecting columns 5 are installed on the cross beam 4. A sound insulation cover 1 is arranged above the four connecting columns 5. The sound insulation cover 1 covers the dry sieve machine body 3, and the inner top wall of the sound insulation cover 1 is installed on the top walls of the four connecting columns 5. An opening is opened at the top of the side wall of the sound insulation cover 1, and the feeding trough passes through this opening to the outside of the sound insulation cover 1. A first sound insulation cotton pad (not shown in the figure) is pasted on the inner side wall of the sound insulation cover 1; a vertical sound insulation curtain 2 is installed on the bottom wall of the sound insulation cover 1. The dry sieve machine body 3 is driven by the motor to vibrate and generate noise, while the first sound insulation cotton pad, the sound insulation curtain 2 on the inner side wall of the sound insulation cover 1 and the ground jointly enclose the space where the dry sieve machine body 3 is located in all directions to block the noise. After the noise breaks through this barrier and overflows to the outside world, it will be weakened into low noise. The sound insulation curtain 2 is made of soft rubber, and the operator can push aside the sound insulation curtain 2 and enter the sound insulation cover 1 to check and maintain the dry sieve machine body 3. A second sound insulation cotton pad 13 is installed on the lower part of the side wall of the second support column 12, and the height position of the second sound insulation cotton pad 13 is the same as that of the sound insulation curtain 2. When the operator pushes aside the sound insulation curtain 2, the second sound insulation cotton pad 13 buffers the sound insulation curtain 2 to avoid generating noise.
[0017] A vertical connecting strip 15 is installed on the bottom wall of the sound insulation cover 1 near the outer peripheral edge. A horizontal limiting strip 14 is installed on the bottom wall of the connecting strip 15. The limiting strip 14 is located outside the sound insulation curtain 2 to block the outer side wall of the sound insulation curtain 2, so as to prevent the sound insulation curtain 2 from fluttering outwards and failing to block the noise.
[0018] As described above, it is only the implementation mode of the present utility model creation, and the scope of patent protection is not limited thereby. Those skilled in the art make non-substantive changes or substitutions based on the present utility model creation, and still fall within the scope of patent protection.
