Description

Technical Field

[0001] The utility model belongs to the technical field of battery plastic separator recycling, in particular to a parallel conveyor for battery plastic separators. Background Art

[0002] Battery plastic separators are a type of plastic product used to separate the positive and negative electrodes inside the battery. Common battery plastic separator materials include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc. Battery separators are usually located between the positive and negative electrodes of the battery to prevent direct contact between the positive and negative electrodes and avoid short circuits. During the charging and discharging process of the battery, a chemical reaction will occur between the positive and negative electrodes. If there is no separator to isolate them, a short circuit may occur. After the battery reaches the end of its service life, it still has recycling value. The battery separator is one part of it. Some chemical substances remain on its surface that can be recycled, and the plastic material itself can also be recycled. It usually needs to go through processes such as crushing and cleaning. However, these processes require the use of corresponding conveyors for transportation. However, there are still the following disadvantages in actual use:

[0003] 1. When recycling battery plastic separators, due to their large size, they usually need to be simply crushed, then transported to the cleaning pool for cleaning, and then input to the crusher for secondary crushing. In this process, there are a lot of broken separator materials. However, these broken materials are usually processed in large quantities. At present, with the increase in recycling volume, conventional single conveyors cannot meet the transportation needs, and the transportation efficiency needs to be increased;

[0004] 2. Secondly, when the washed partition fragments are transported, there may still be a certain amount of moisture on their surface, which may affect the subsequent secondary crushing effect. However, if a drying step is added, it will affect the processing time and efficiency. Therefore, it is necessary to dry them as much as possible during the transportation process.

The two frames 101 are rotatably connected with two conveying rollers 105. Two rubber ring strips 106 are commonly sleeved outside the two conveying rollers 105. The two rubber ring strips 106 are commonly sleeved outside the two rubber ring strips 106. The flexible conveying belt 104 is commonly sleeved outside;

[0033] Two symmetrical annular grooves 1051 are formed on the outer circumference of each conveying roller 105, and the inner annular surface of the rubber ring strip 106 is inserted into the annular groove 1051, and the outer annular surface of the rubber ring strip 106 exceeds the outer circumferential surface of the conveying roller 105;

[0034] The parallel arrangement of two belt conveyors 1 can increase the conveying efficiency and can simultaneously convey a large amount of partition plate fragments, which is convenient for use when a large amount of partition plates are recycled. Two frames 101 are used as carriers, and corresponding conveying rollers 105 are installed. The rotation of the two conveying rollers 105 can drive the flexible conveyor belt 104 to convey the partition plate fragments. A rubber ring strip 106 is arranged between the conveying roller 105 and the flexible conveyor belt 104 to increase the stability of the connection and avoid insufficient friction of the flexible conveyor belt 104.

[0035] Each belt conveyor 1 is covered with an inverted U-shaped cover 5, and a lower hopper 4 is provided below the discharge of the two belt conveyors 1;

[0036] The cover 5 can be set to protect the partition plate fragments during the conveying process, so that they will not fall outside the belt conveyor 1. The partition plate fragments conveyed by the two belt conveyors 1 are finally concentrated in the lower hopper 4 and guided to the outside.

[0037] An air pipe 2 is arranged between the two belt conveyors 1. Two rows of symmetrically distributed branch pipes 201 are fixedly passed through the circumference of the air pipe 2. Each row of branch pipes 201 passes through the adjacent frame 101 and extends into the inner cavity of the adjacent flexible conveyor belt 104.

[0038] Compressed air is input into the air pipe 2 and enters the branch pipe 201, and the branch pipe 201 extends into the inner cavity of the flexible conveyor belt 104 to assist in drying the subsequently transported partition board fragments.

[0039] Each belt conveyor 1 further includes a support leg 102 and a reinforcing plate 103. Two symmetrical support legs 102 are fixed to the bottom of the two frames 101, and a reinforcing plate 103 is fixed to the outside of all the support legs 102.

[0041] A transmission assembly 3 is provided on the side away from each other of the two belt conveyors 1. The transmission assembly 3 includes a motor 301 fixed on the reinforcing plate 103 and a pulley 1 302 fixed on the output shaft of the motor 301. A pulley 2 303 is fixed on the end of a conveying roller 105 close to the feeding end of the belt conveyor 1. The pulley 1 302 and the pulley 2 303 are on the same side of the belt conveyor 1, and a linkage belt 304 is provided on the outside of the pulley 1 302 and the pulley 2 303.

[0042] When the belt conveyor 1 is working, the motor 301 works to drive the pulley 1 302 to rotate. Under the action of the linkage belt 304, the pulley 2 303 rotates accordingly, and the conveying roller 105 rotates accordingly, so that the flexible conveyor belt 104 operates and conveys.

[0043] The upper ends of the two racks 101 are provided with equally spaced plug holes 1011, and the two bottom surfaces of the cover 5 are fixed with equally spaced plug posts 502, and the plug posts 502 are inserted into the plug holes 1011 below them;

[0044] The cover 5 is arranged above the flexible conveyor belt 104 to prevent the partition fragments conveyed thereon from falling off. The cover 5 is inserted into the insertion hole 1011 through the insertion column 502 to maintain a certain connection with the frame 101 so that it will not deviate.

[0045] A triangular bar 501 is fixed on the inner wall of the two vertical parts of the cover 5, and the inclined surfaces of the two triangular bars 501 are arranged opposite to each other, the vertical right-angle surface of the triangular bar 501 is fixed to the inner wall of the cover 5, and the horizontal right-angle surface of the triangular bar 501 contacts the upper surface of the flexible conveyor belt 104 and keeps it horizontal;

[0046] The setting of the triangular bar 501 ensures that when the air nozzle 2011 on the branch pipe 201 blows up the crushed materials and then drops them, they will not get stuck in the gap between the frame 101 and the flexible conveyor belt 104. This ensures that after the crushed materials are blown up, they can slide along the inclined surface of the triangular bar 501 onto the flexible conveyor belt 104 without getting stuck.

[0047] The surface of the flexible conveyor belt 104 is provided with equally spaced hollow holes 1041, and the upper part of the branch pipe 201 extending into the inner cavity of the flexible conveyor belt 104 is fixed with equally spaced air nozzles 2011, and the number of the air nozzles 2011 corresponds to the number of a row of hollow holes 1041, and the air outlet end of the air nozzle 2011 faces the hollow hole 1041 above it, and the end of the air pipe 2 away from the lower hopper 4 is fixed with a connecting pipe 202;

[0048] The hollow hole 1041 is provided so that the air blown out from the air nozzle 2011 on the branch pipe 201 can pass through the flexible conveyor belt 104 and blow toward the partition fragments being transported above it, thereby drying them and removing moisture from the surface, thus facilitating drying during the transportation process and saving steps. The air pipe 2 is connected to an external air source via the connecting pipe 202.

[0049] The specific working principle of the utility model is as follows: first, two belt conveyors 1 are arranged in parallel, with two frames 101 as carriers, corresponding conveying rollers 105 are installed, rubber ring strips 106 are set outside the two conveying rollers 105, and a fixed flexible conveying belt 104 is set outside the rubber ring strips 106, and the rubber ring strips 106 are clamped in the ring groove 1051, so that the operation is more stable and does not deviate. Then the motor 301 works to drive the pulley 1 302 to rotate. Under the action of the linkage belt 304, the pulley 2 303 rotates, and the conveying roller 105 rotates accordingly, so that the flexible conveying belt 104 runs and conveys. When the partition plate fragments are in the belt When conveying on the flexible conveyor 1, the air pipe 2 is connected to the external air source through the connecting pipe 202, and compressed air is input into the air pipe 2, and then sprayed out from the air nozzle 2011 on the branch pipe 201, and blown through the hollow hole 1041 toward the partition crushed materials on the flexible conveyor belt 104, so as to dry the partition crushed materials. The crushed materials can also be blown and turned on the flexible conveyor belt 104, but are blocked by the cover 5 and will not fall out. The blown crushed materials can also slide along the inclined surface of the triangular bar 501 to the flexible conveyor belt 104, and no material jamming will occur. The partition crushed materials transported by the two belt conveyors 1 are finally concentrated in the lower hopper 4 and guided to the next process.
