Description

Technical Field

[0001] The present invention relates to the technical field of refining equipment, and more specifically, to a multi-stage separation device for lead-tin recovery processing. Background Art

[0002] Lead-tin alloy is widely used in industry, mainly in the electroplating industry. By changing the ratio of lead and tin in the alloy, different effects can be achieved, such as anti-corrosion coatings, wear-resistant coatings, corrosion-resistant welding, etc.

[0031] The rotating motor 43 is fixedly mounted on the outer wall of the sorting machine housing 1, and a screen 44 is provided on one side of the feeding belt 41. The screen 44 is fixedly mounted on the outer wall of the sorting machine housing 1, and the outer wall of the screen 44 fits with the outer wall of the feeding belt 41. The roller 42 driven by the rotating motor 43 makes the feeding belt 41 rotate, and the feeding belt 41 collects the material falling from the bottom of the crushing wheel 3 and drives it to be screened through the screen 44, so that the large materials in the material are temporarily retained and separated.

[0032] like Figure 3 and Figure 4As shown, a first pulley 45 is fixedly mounted on the outer wall of the roller shaft 42, a synchronous belt 46 is rotatably mounted on the outer wall of the first pulley 45, a second pulley 47 is rotatably mounted on one side of the synchronous belt 46, and the second pulley 47 is rotatably mounted on the outer wall of the sorting machine housing 1, so that when the roller shaft 42 rotates, it drives the first pulley 45 to drive the second pulley 47 to rotate synchronously through the synchronous belt 46.

[0033] like Figure 4 and Figure 5 As shown, a dispersing impeller 48 is fixedly installed on one side of the second pulley 47, and the dispersing impeller 48 is rotatably installed on the inner wall of the sorting machine housing 1. The dispersing impeller 48 is arranged in a horizontal state, and the dispersing impeller 48 and the screening mesh 44 are arranged in an interlaced manner. A return hopper 49 is provided at the bottom of the dispersing impeller 48, and the return hopper 49 is fixedly installed on the inner wall of the sorting machine housing 1. The return hopper 49 passes through the outer wall of the sorting machine housing 1, and the second pulley 47 drives the dispersing impeller 48 to rotate synchronously and pass through the screening mesh 44 to sweep away the large pieces of material on it, and finally the material is sent to the return hopper 49 to be taken away.

[0034] like Figure 3 and Figure 6 As shown, the vibrating screening mechanism 5 includes a lower hopper 51 arranged at the bottom of the screening mesh 44, the lower hopper 51 is fixedly mounted on the inner wall of the sorting machine housing 1, and a metal vibrating screening bucket 52 is provided at the bottom of the lower hopper 51, the metal vibrating screening bucket 52 is arranged upwardly inclined, and a coupling roller 53 is fixedly mounted at the bottom of the metal vibrating screening bucket 52, and the coupling roller 53 is rotatably mounted on the inner wall of the sorting machine housing 1, then the material passing through the screening mesh 44 falls into the lower hopper 51 and is brought to the metal vibrating screening bucket 52, and is completely collected by the metal vibrating screening bucket 52.

[0035] like Figure 3 and Figure 6 As shown, a discharge hopper 54 is provided on one side of the metal vibrating sieve bucket 52, and the discharge hopper 54 is arranged on the outer wall of the separator housing 1. A convex pad 55 is provided at the bottom of the metal vibrating sieve bucket 52, and the convex pad 55 is rotatably mounted on the inner wall of the separator housing 1. The height of the convex pad 55 is higher than the height of the distance between the metal vibrating sieve bucket 52 and the convex pad 55, and a reduction motor 57 is provided on one side of the convex pad 55;

[0036] Then, the reduction motor 57 drives the convex pad 55 to rotate, and the convex pad 55 intermittently lifts the metal vibrating sieve bucket 52, and the connecting roller 53 at the bottom of the metal vibrating sieve bucket 52 makes one side of the metal vibrating sieve bucket 52 be lifted up and dropped reciprocatingly, so that the metal vibrating sieve bucket 52 continuously swings to vibrate the material, that is, due to the different weights of the plastic parts and the lead-tin alloy material, the lighter plastic parts in the material gradually move to one side due to the larger swing amplitude, so that the plastic parts are located at a more forward position of the metal vibrating sieve bucket 52.

[0037] like Figure 6 and Figure 7As shown, magnet blocks 58 are provided on both sides of the top of the metal vibrating sieve bucket 52. When the metal vibrating sieve bucket 52 moves upward, it approaches and absorbs the magnet blocks 58. A belt turning plate 59 is fixedly installed on one side of the two magnet blocks 58. The belt turning plate 59 is rotatably installed on the inner wall of the sorting machine housing 1. A limited tension spring 510 is fixedly installed on the top of the two magnet blocks 58. The limited tension spring 510 is fixedly installed on the inner wall of the sorting machine housing 1.

[0038] When the metal vibrating sieve bucket 52 falls, the magnet block 58 is pulled to drive the flip plate 59 to deflect downward and stretch the tension-limiting spring 510. A sweeping plate 511 is fixedly installed on one side of the flip plate 59, thereby driving the sweeping plate 511 to deflect downward and sweep out the plastic parts located further forward of the metal vibrating sieve bucket 52. After the magnet block 58 is pulled to a certain distance by the falling metal vibrating sieve bucket 52, it is elastically pulled apart by the tension-limiting spring 510 and reset.

[0039] like Figure 6 and Figure 8 As shown, a supporting mechanism 6 is provided at the bottom of the discharge hopper 54, and the supporting mechanism 6 includes a supporting plate 61 provided at the bottom of the discharge hopper 54, the supporting plate 61 is provided in a vertical state, the top of the supporting plate 61 is in contact with the bottom of the discharge hopper 54, and a sliding top plate 62 is fixedly installed at the bottom of the supporting plate 61, and the sliding top plate 62 is slidably installed on the inner wall of the sorting machine housing 1, and the supporting plate 61 driven by the sliding top plate 62 is pressed against the bottom of the discharge hopper 54 so that the discharge hopper 54 is located at a high place.

[0040] like Figure 6 and Figure 8 As shown, a top protrusion 63 is provided on one side of the sliding top plate 62, and the top protrusion 63 is arranged in a vertical state. The top of the top protrusion 63 is in contact with the outer wall of the sliding top plate 62, and a turning handle 64 is installed at a height of one side of the top protrusion 63. The state of the top protrusion 63 is controlled by the turning handle 64, and the sliding top plate 62 is vertically lifted by the top protrusion 63.

[0041] In specific implementation, the roller 42 driven by the rotating motor 43 makes the feeding belt 41 rotate, and the feeding belt 41 collects the materials falling from the bottom of the crushing wheel 3 and drives them to pass through the screening net 44 for screening, so that the large materials in the materials are temporarily separated, and then the roller 42 drives the first pulley 45 to drive the second pulley 47 to rotate synchronously through the synchronous belt 46, and the second pulley 47 drives the scattering impeller 48 to rotate synchronously and pass through the screening net 44 to sweep away the large pieces of materials on it, and finally the materials are sent to the return hopper 49 to be taken away;

[0042] The materials passing through the screen mesh 44 fall into the lower hopper 51 and are brought to the metal vibrating sieve hopper 52, where they are all collected. The reduction motor 57 drives the convex pad 55 to rotate, and the convex pad 55 intermittently lifts up the metal vibrating sieve hopper 52, and the coupling roller 53 at the bottom of the metal vibrating sieve hopper 52 causes one side of the metal vibrating sieve hopper 52 to be lifted up and dropped back and forth. The metal vibrating sieve hopper 52 continuously swings and vibrates the materials, that is, due to the different weights of the plastic parts and the lead-tin alloy material, the light plastic parts in the material gradually move to one side due to the larger swing amplitude, so that the plastic parts are located at a more front side of the metal vibrating sieve hopper 52;

[0043] At the same time, when the metal vibrating sieve bucket 52 moves upward, it approaches and absorbs the magnet block 58. When the metal vibrating sieve bucket 52 falls, it pulls the magnet block 58 to drive the belt turning plate 59 to deflect downward and stretch the limit spring 510, driving the sweeping plate 511 to deflect downward and sweep out the plastic parts located at the front side of the metal vibrating sieve bucket 52. After the magnet block 58 is pulled to a certain distance by the falling metal vibrating sieve bucket 52, it is elastically pulled away by the limit spring 510 and reset.

[0044] First, the support plate 61 driven by the sliding top plate 62 is pressed against the bottom of the discharge hopper 54 so that the discharge hopper 54 is located at a high place, and then the plastic parts discharged first are collected together, and then the state of the top protrusion 63 is controlled by the turning handle 64, and the top protrusion 63 rotates to release the sliding top plate 62, and then the sliding top plate 62 falls and drives the support plate 61 to make one side of the discharge hopper 54 fall. At this time, the reduction motor 57 is stopped to drive the convex pad 55, that is, the discharge hopper 54 is tilted downward to pour out the remaining lead-tin alloy material for recycling.
