Description

Technical Field

[0001] This invention relates to the field of PP sheet recycling and crushing technology, specifically to a waste recycling device for PP sheet production. Background Technology

[0002] PP sheet is a semi-crystalline material that is harder and has a higher melting point than PE. It is commonly used in acid and alkali resistant equipment, environmental protection equipment, wastewater and exhaust gas emission equipment, scrubbing towers, clean rooms, semiconductor plants, and related industrial equipment. Thick PP sheets are widely used as stamping plates and punch press plates. During the production and processing of PP sheets, excess burrs need to be removed, and the sheets also need to be cut to produce different specifications. This generates excess PP waste. Directly discarding this waste would be a waste of resources, so it is necessary to recycle it.

[0003] Existing waste recycling equipment for PP sheet production easily generates dust during waste crushing and accumulates stains on the surface of the waste during recycling, thus affecting the quality of the subsequently recycled materials. The equipment has relatively simple functions and cannot automatically complete a series of processes such as waste cleaning, conveying, crushing, and drying during the recycling operation, which affects the recycling efficiency.

[0020] The rinsing and conveying mechanism also includes a filter pump 8 fixedly installed in the body 1.

A partition platform 22 and a guide plate 23 are fixedly connected inside the machine body 1. A control shaft 24 is rotatably connected inside the machine body 1. Multiple sets of screening shovels 25 are evenly fixedly connected to the outer wall of the control shaft 24.

The machine body 1 is provided with auxiliary parts for filtering and drying the output waste. The drive unit can rotate in conjunction with the control shaft 24.

[0024] The auxiliary components include a storage box 27 fixedly installed inside the machine body 1, a second screen 28 fixedly connected inside the storage box 27, the top surface of the second screen 28 being inclined and flush with the top surface of the partition table 22, one end of the extraction pipe 10 being connected to the bottom end of the storage box 27, and the auxiliary components also include a dryer 39 fixedly installed above the storage box 27, and a box door 40 hinged to the side of the storage box 27.

[0025] The driving component includes a drive motor 29 fixedly installed inside the body 1. The drive motor 29 is preferably model Y80M1-2. The output end of the drive motor 29 is coaxially fixedly connected to a drive shaft 30. A reciprocating lead screw 31 is coaxially fixedly connected to the drive shaft 30. A drive gear 32 is coaxially fixedly connected to the side of the semi-cylinder 5. A drive block 33 is slidably connected in the horizontal direction inside the body 1. The reciprocating lead screw 31 passes through the drive block 33 and is threadedly connected to the drive block 33. A rack 34 that meshes with the drive gear 32 is fixedly connected to the bottom of the drive block 33. The drive shaft 30 is provided with a rotating component for driving the rotating shaft 19 and the control shaft 24 to rotate. The rotating component includes a worm gear 35 coaxially fixedly installed at one end of the drive shaft 30. A worm wheel 36 that meshes with the worm gear 35 is coaxially fixedly connected to one end of the control shaft 24. The drive shaft 30 is connected to a transmission belt 37 that is connected to the pulley on the rotating shaft 19 via a pulley drive.

[0026] In this embodiment, clean water is filled inside the machine body 1, with the water level positioned below the rotating shaft 19 at a required distance. A predetermined amount of PP board waste to be crushed and recycled is input into the machine body 1 through the input tank 2. The waste floats on the water, causing the water level to rise. It is necessary to ensure that the water level remains below the rotating shaft 19 after the rise. The filter pump 8 is then activated, causing the pumping pipe 10 and pumping tank 11 to draw water from the bottom of the input tank 2, conveying tank 3, output tank 4, and storage tank 27, respectively. The filtered impurities are stored in the collection tank of the filter pump 8. Inside, the filtered water is transported to the connecting pipe 15 through the output pipe 14, and then discharged through the water outlet 6. When the material is fed in, the arc side of the semi-cylinder 5 rotates to a position close to the fixed cover 16, and the water outlet 6 on the flat side tilts towards the input tank 2. Since the PP waste will float on the surface of the liquid, the bottom end of the semi-cylinder 5 blocks the waste from sinking into the conveying tank 3. At this time, the water outlet 6 continuously discharges clean water, causing the water in the input tank 2 to flow around, thoroughly cleaning the waste, and the sewage is extracted and filtered through the pumping tank 11, improving the cleaning efficiency.

[0027] The drive motor 29 is started to drive the drive shaft 30 to rotate. The drive shaft 30 drives the reciprocating screw 31 to make the drive block 33 slide horizontally back and forth, thereby causing the rack 34 to drive the drive gear 32 to rotate. During the reciprocating rotation of the drive gear 32, the semi-cylinder 5 can be driven to rotate back and forth. When the arc surface of the semi-cylinder 5 rotates towards the input groove 2, the flat side of the semi-cylinder 5 presses the waste in the input groove 2 into the water body. As the semi-cylinder 5 rotates 90°, the waste can be pushed towards the fixed cover 16 for subsequent crushing. At this time, the water outlet 6 will drain water towards the fixed cover 16. The water flow will push the floating waste to move continuously towards the position of the first screen 21, improving the crushing and conveying efficiency. Afterwards, the semi-cylinder 5 rotates 90° in the opposite direction to perform the subsequent feeding and rinsing operation again.

[0028] During the rotation of the drive shaft 30, the transmission belt 37 is driven to rotate the rotating shaft 19. The thread pitch of the reciprocating screw 31 is small, resulting in a relatively slow movement speed of the drive block 33 during rapid rotation. Meanwhile, the rotating shaft 19 closer to the transmission belt 37 rotates at a relatively faster speed. After being reduced in speed by the planetary gear reducer 20, the speed of the adjacent rotating shaft 19 decreases, thus sequentially transmitting the effect of decreasing speed of the crusher blade 7 towards the semi-cylinder 5. Lower speeds result in relatively higher torque, generating stronger crushing force on large pieces of waste. It should be noted that the crusher blade closer to the semi-cylinder 5... The rotational speed of the 7th blade is lower than that of the other side, but it is still relatively high, which can produce a good crushing effect on large pieces of waste. During the rotation of the 7th blade, the inclined plane 38 will generate a thrust on the water body to push the first screen 21, which will help the waste to flow to the side of the first screen 21. As the waste moves, it will be gradually crushed by the faster 7th blade, and the waste particles will gradually become smaller. At the same time, during the crushing process, the water body can fully float the waste and push it to the position of the 7th blade. The dust generated by the crushing and the impurities adhering to the waste will be adsorbed and collected by the water body.

[0029] Waste material of suitable particle size is conveyed to the output trough 4 after passing through the first screen 21. The drive shaft 30 drives the worm gear 35 to rotate, and the worm gear 35 drives the worm wheel 36 to rotate the control shaft 24. The control shaft 24 drives the screening shovel 25 to rotate, which picks up the waste particles in the output trough 4 and filters out some of the water. The waste particles are then thrown above the second screen 28. As the waste rolls down the second screen 28, the water is filtered into the storage box 27 below. The dryer 39 above can further dry the waste particles. The dried waste particles can be discharged and recycled by opening the box door 40.

[0030] It is worth noting that the filter pump 8 can pump and filter the impurities in the water at the bottom of the storage tank 27, input tank 2, conveying tank 3 and output tank 4. The impurities collected by the filter pump 8 can be cleaned periodically. The equipment has a high degree of automation and can use the buoyancy of the water to transport and float the PP waste upward, increase the thrust required in the crushing process, ensure crushing efficiency and achieve dust reduction and cleaning functions. The water is recycled, which is environmentally friendly and efficient.
