Description

Technical Field

[0001] The utility model relates to the technical field related to screening devices, in particular to a screening device for crushing and recovering scandium-containing waste materials. Background Art

[0002] Scandium is a silvery-white transition metal element and a rare metal. Therefore, when scandium-containing waste is discharged, it needs to be crushed to recover the scandium element. In order to better recycle the scandium-containing waste, the crushed scandium-containing waste needs to be screened to classify it according to its size.

[0003] When existing screening devices are used to screen and classify crushed scandium-containing waste, most of the crushed scandium-containing waste is screened through screens of different specifications. This screening method can achieve the screening effect, but the crushed scandium-containing waste cannot be screened at a uniform speed during screening, resulting in the problem of excessively fast conveying speed of the scandium-containing waste and poor screening quality, which further reduces the working efficiency of the screening device.

[0004] For this purpose, we propose a screening device for crushing and recycling scandium-containing waste materials. Utility Model Content

[0008] Furthermore, the jet mechanism includes a piston cylinder fixed to the side wall of the screening box, the interior of the piston cylinder is slidably connected to a piston rod, the end of the piston rod is affixed to a cam, the surface of the piston cylinder is respectively fixedly connected to an air inlet pipe and an air outlet pipe, the surface of the air outlet pipe is connected to a plurality of jet nozzles, and the ends of the jet nozzles pass through the inner top wall of the lower hopper.

[0010] Furthermore, a return spring is sleeved on the surface of the piston rod, and the end of the return spring is fixedly connected to the piston cylinder.

[0011] Furthermore, the screening mechanism includes a screening drum fixed on the inner wall of the screening box, and the bottom of the screening drum is respectively provided with a first sieve hole, a second sieve hole, a third sieve hole and a fourth sieve hole, and the first sieve hole, the second sieve hole, the third sieve hole and the fourth sieve hole are respectively arranged from left to right.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] The utility model cooperates with the feeding mechanism, the servo motor, the stirring shaft and the auger, so that the scandium-containing waste material inside the screening mechanism can be moved at a uniform speed. By setting it in this way, the scandium-containing waste material can be better screened under uniform movement, avoiding the problem of poor screening quality caused by excessively fast conveying speed of the scandium-containing waste material, and further improving the working efficiency of the screening device.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 4 The utility model provides a technical solution: a screening device for crushing and recycling scandium-containing waste, comprising a screening box 1, the inner wall of the screening box 1 is fixedly connected to a screening mechanism 2, the top of the screening mechanism 2 is fixedly connected to a feed hopper 3, the bottom of the screening box 1 is fixedly connected to a plurality of lower hoppers 4, the lower hoppers 4 are attached to the bottom of the screening mechanism 2, and the side wall of the screening box 1 is fixedly connected to a feeding mechanism 5; wherein the feeding mechanism 5 includes a servo motor 51 fixed to the side wall of the screening box 1, the output end of the servo motor 51 is fixedly connected to a stirring shaft 52, the surface of the stirring shaft 52 is fixedly connected to an auger 53, the auger 53 is attached to the inside of the screening mechanism 2, and the servo motor 51 is driven so that the stirring shaft 52 can drive the auger 53 to rotate. When the auger 53 rotates, the scandium-containing waste inside the screening mechanism 2 can be evenly stirred and transported, so that the screening effect can be better.

[0023] according to Figure 2 It can be seen that the ends of the stirring shaft 52 respectively pass through the screening mechanism 2 and the screening box 1 and are extended and fixedly connected with the cam 54. The top of the cam 54 is fitted with a jet mechanism 6, and the jet mechanism 6 is fixed on the other side of the screening box 1. Through the rotation of the stirring shaft 52, the cam 54 can be rotated, and the rotation of the cam 54 can drive the jet mechanism 6 to work. The jet mechanism 6 can release gas into the inside of the screening mechanism 2, so that the scandium-containing waste material inside the screening mechanism 2 can be quickly discharged under the release of gas.

[0024] according to Figure 3It can be seen that the jet mechanism 6 includes a piston cylinder 61 fixed to the side wall of the screening box 1, and a piston rod 62 is slidably connected to the inside of the piston cylinder 61. The end of the piston rod 62 fits on the cam 54. The surface of the piston cylinder 61 is fixedly connected to the air inlet pipe 63 and the air outlet pipe 64. The surface of the air outlet pipe 64 is connected to a plurality of air nozzles 65. The end of the air nozzle 65 passes through the top wall of the lower hopper 4. Through the sliding of the piston rod 62 inside the piston cylinder 61, when the piston rod 62 moves downward, it can open the one-way valve on the surface of the air inlet pipe 63, and on the contrary, the air outlet pipe 64 is opened. The one-way valve on the surface of air pipe 64 is closed, allowing outside air to be drawn into the interior of piston cylinder 61. When piston rod 62 moves upward, the gas inside piston cylinder 61 is released, thereby opening the one-way valve on the surface of outlet pipe 64. Conversely, the surface of inlet pipe 63 is closed. The released gas is transported through outlet pipe 64 and evenly released into the interior of screening mechanism 2 through air nozzle 65, thereby providing air jet treatment inside screening mechanism 2 and preventing the scandium-containing waste from clogging the screening mechanism 2.

[0025] according to Figure 3 It can be seen that the bottom of the piston rod 62 is fixedly connected to a contact plate 66, which is attached to the cam 54. By setting the contact plate 66 at the bottom of the piston rod 62, the contact plate 66 and the cam 54 are in contact, thereby increasing the contact area and achieving a better driving effect.

[0026] according to Figure 3 It can be seen that a return spring 67 is sleeved on the surface of the piston rod 62, and the end of the return spring 67 is fixedly connected to the piston cylinder 61. Through the rebound force of the return spring 67, the contact plate 66 can be automatically reset.

[0027] according to Figure 4 It can be seen that the screening mechanism 2 includes a screening drum 21 fixed on the inner wall of the screening box 1, and the bottom of the screening drum 21 is respectively provided with a first sieve hole 22, a second sieve hole 23, a third sieve hole 24 and a fourth sieve hole 25, and the first sieve hole 22, the second sieve hole 23, the third sieve hole 24 and the fourth sieve hole 25 are respectively arranged from left to right, so that the first sieve hole 22, the second sieve hole 23, the third sieve hole 24 and the fourth sieve hole 25 are respectively arranged from left to right, so that the size can be screened from small to large, thereby screening the scandium-containing waste sizes of different sizes.

[0028] The working principle of the present invention is as follows: when in use, the screening mechanism 2 is installed and fixed by the screening box 1, and then the feed hopper 3 on the top of the screening mechanism 2 is set so that the crushed scandium-containing waste can be put into the feed hopper 3 and finally enter the screening mechanism 2. The scandium-containing waste screened by the screening mechanism 2 can be classified and stored through the lower hopper 4. The feeding mechanism 5 is driven so that the scandium-containing waste inside the screening mechanism 2 can be stirred and transported, so that it can be screened at a uniform speed through different screening holes of the screening mechanism 2. The servo motor 51 is driven so that the stirring shaft 52 can be driven to rotate, so that the auger 53 can be driven to rotate, and the scandium-containing waste inside the screening mechanism 2 can be transported by the rotation of the auger 53.
