Description

Technical Field

[0001] The utility model relates to the technical field of recycling waste photovoltaic battery groups, in particular to a waste photovoltaic battery recycling separation and extraction device. Background Art

[0002] Photovoltaic cells, also known as solar panels, are the core part of solar power generation systems. Their service life is usually around 20 to 30 years. With the extensive use of photovoltaic cells and the gradual end of their service life, their recycling has become an important issue. Recycling can not only reduce environmental pollution, but also recycle the rare metals and renewable materials contained in them.

[0003] During recycling, the used photovoltaic panels are first removed from the installation location, and then mechanical equipment such as crushers or cutters are used to break the panels. After breaking, the air separator uses aerodynamic principles to separate light non-metallic materials such as glass fragments from heavier metal materials based on the density and shape differences of the materials. The metal materials can be recycled or further purified, and other non-metallic materials are separated again by chemical or other methods.

[0004] When some existing separation and extraction equipment is used for separation, the air separator will consume a lot of energy to generate wind power. At the same time, the air separator has high requirements on the density, shape and humidity of the material. If the material does not meet the working requirements of the air separator, that is, the broken fragments are too large or too small, it will easily affect the sorting effect and lead to incomplete separation of metals and non-metals.

[0036] When the broken battery fragments fall into the beveled screen block 7, the vibrator 27 is started to vibrate, and the fragments that meet the size of the bottom hole will fall down, and the fragments that do not meet the size and are too large will slide into the conveying frame 22 and finally enter the lifting frame 23. When the beveled screen block 7 vibrates, it is damped by multiple shock absorbers 20 respectively fixed at the bottom of the two extension blocks 21. The multiple shock absorbers 20 are fixed and supported by two supporting blocks 19 to prevent the vibration from affecting the two L-shaped frames 2. The motor three 25 is started to drive the auger 26 to rotate, driving the battery fragments transmitted by the conveying frame 22 to the lifting frame 23 to move upward.

[0038] When the magnetic conveyor belt 18 drives the battery fragments to move to the right, the extension plate 28 is used to prevent the battery fragments from falling to both sides. When the fragments reach the position of the limit plate 30, the part of the fragments above the limit plate 30 will enter the fixed frame 29, and the remaining fragments will remain at the bottom of the limit plate 30 and be transmitted to the right, so as to prevent too much fragments from being adsorbed by the magnetic conveyor belt 18 and affecting subsequent separation. When the fragments on the magnetic conveyor belt 18 are lower than the magnetic conveyor belt 18, the electric push rod 32 is started to push the push plate 31 to the right, and push the fragments in the fixed frame 29 to the right onto the magnetic conveyor belt 18, so that these fragments are transported to the right for separation.

[0039] Reference Figure 1 and Figure 4 A chute 14 is provided on the right side of the bottom plate 1, and the delivery chute 12, the delivery chute 2 13 and the chute 14 are interconnected.

When the magnetic transmission belt 18 moves the fragments to the rightmost part, these fragments of non-metallic materials will fall into the delivery slot 12 and enter the collecting drawer 15, and the fragments of metallic materials will be adsorbed on the outer wall of the magnetic transmission belt 18 and driven to the bottom. When reaching the bottom, the metallic material fragments on the outer wall of the magnetic transmission belt 18 are scraped off by the scraper 11 and fall into the delivery slot 2 13 and finally enter the placement slot 16. When the fragments transmitted on the magnetic transmission belt 18 are lower than the magnetic transmission belt 18, the electric push rod 32 is started to make the push plate 31 push the fragments in the fixed frame 29 to the right onto the magnetic transmission belt 18, wherein the fragments with metallic materials are adsorbed by the magnetic transmission belt 18 again, and at the same time, these fragments continue to be transported to the right and separated by the magnetic transmission belt 18.
