Description

Technical Field

[0001] This utility model relates to the field of waste plastic recycling and processing technology, and in particular to a waste plastic particle salt separation pool device. Background Technology

[0002] The salt separation method for waste plastics achieves the separation of particles of different materials by adjusting the density of the salt solution. However, traditional salt separation tanks have defects in the transfer of materials after separation. Specifically, during the discharge of the separated material, the plastic floating on the surface of the salt solution relies on separate mechanical equipment to be retrieved or discharged through the top overflow port. The operation is prone to disturbing the tank, causing the plastic at the bottom of the tank to be secondary-entrained and easily cross-contaminated. When the plastic at the bottom of the tank is discharged through the bottom valve, the high-concentration salt solution mixes with the plastic and flows out, requiring an additional solid-liquid separation device. The process is complicated and the salt solution is lost in large quantities. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, the purpose of this utility model is to provide a waste plastic particle salt separation tank device, which facilitates the separate discharge of floating plastic and bottom plastic in the salt separation process, and reduces salt overflow.

[0005] To achieve the above objectives, this utility model proposes a waste plastic pellet salting tank device, including a salting tank and a salting discharge mechanism and a slag discharge mechanism disposed inside the salting tank. The salting discharge mechanism includes a first conveyor belt and a first reflux plate, wherein the first reflux plate is inclinedly disposed on one side of the salting tank, and the first conveyor belt is disposed inside the first reflux plate. The slag discharge mechanism includes a second conveyor belt and a second reflux plate, wherein the second reflux plate is inclinedly disposed on the other side of the salting tank, and the second conveyor belt is disposed inside the second reflux plate. The length of the second conveyor belt is greater than that of the first conveyor belt, and the feed end of the second conveyor belt is located below the first conveyor belt. The surfaces of the first and second conveyor belts are both perforated mesh structures. A partition assembly is provided on the top of the salting tank.

[0006] Furthermore, the baffle assembly includes a baffle disposed at the top of the salt separation tank, with baffle adjustment seats at both ends for adjusting its height, and a feeding mechanism disposed at the top of the salt separation tank, the feeding mechanism being located between the baffle and the first conveyor belt.

[0008] Furthermore, baffles are provided on both the first and second conveyor belts, a first fan is provided above the first conveyor belt, and a second fan is provided above the second conveyor belt.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The waste plastic particle salt separation tank device of this utility model is described below with reference to the accompanying drawings.

[0020] like Figures 1-3 As shown, the waste plastic pellet salt separation pool device provided in this embodiment of the present invention includes a salt separation pool 5 and a salt separation discharge mechanism 1 and a slag discharge mechanism 4 disposed inside the salt separation pool 5.

[0021] The salt separation discharge mechanism 1 includes a first conveyor belt 12 and a first reflux plate 11, wherein the first reflux plate 11 is inclinedly arranged on one side of the salt separation tank 5, and the first conveyor belt 12 is arranged inside the first reflux plate 11.

[0022] The slag discharge mechanism 4 includes a second conveyor belt 42 and a second reflux plate 43. The second reflux plate 43 is inclinedly arranged on the other side of the salt separation tank 5. The second conveyor belt 42 is arranged inside the second reflux plate 43. The length of the second conveyor belt 42 is greater than that of the first conveyor belt 12, and the feed end of the second conveyor belt 42 is located below the first conveyor belt 12. A support guide roller 44 is provided at the bottom of the second conveyor belt 42. The surfaces of the first conveyor belt 12 and the second conveyor belt 42 are both perforated mesh structures. A baffle assembly 3 is provided at the top of the salt separation tank 5, and a support 51 is provided at the bottom of the salt separation tank 5.

[0023] Specifically, in use of the salt separation tank 5 device of this application, salt solution is injected into the salt separation tank 5 and the concentration is adjusted. After the salt solution concentration is adjusted to a suitable level, the plastic to be salted is gradually placed into the salt separation tank 5. The less dense plastic floats on the surface of the salt solution, while the denser plastic gradually falls and lands on the inclined second conveyor belt 42 at the bottom of the salt separation tank 5, and the floating plastic is gradually transferred out. As the floating plastic accumulates on the surface of the salt solution, it enters the inclined first conveyor belt 12 and is gradually transferred upwards.

[0024] The baffle assembly 3 is used to separate floating plastic and prevent it from entering the second conveyor belt 42. During the plastic transfer process, the brine passes through the mesh first conveyor belt 12 and the second conveyor belt 42, and flows back to the salt separation tank 5 through the first return plate 11 and the second return plate 43, reducing brine overflow.

[0025] In one embodiment of this utility model, such as Figure 3 As shown, the partition 31 has partition adjustment seats 32 at both ends for adjusting its height. The top of the salt separation tank 5 is provided with a feeding mechanism 2, which is located between the partition 31 and the first conveyor belt 12. The feeding mechanism 2 includes a feeding hopper 21 and a cloth distribution cylinder 22. The cloth distribution cylinder 22 spans the top of the salt separation tank 5. The feeding hopper 21 is located at the feed end of the cloth distribution cylinder 22. The cloth distribution cylinder 22 has a cloth distribution spiral shaft 24 inside. The bottom of the cloth distribution cylinder 22 is provided with a straight discharge nozzle 25. A cloth distribution drive motor 23 for driving the cloth distribution spiral shaft 24 to rotate is provided on one side of the cloth distribution cylinder 22.

[0026] Specifically, since the feeding mechanism 2 is located between the partition 31 and the first conveyor belt 12, it effectively prevents floating plastic from entering the right side of the partition 31 and prevents floating plastic from mixing onto the second conveyor belt 42. The depth to which the partition 31 is inserted into the brine is adjusted by the partition adjustment seat 32 to adjust the partition depth according to different plastic particle sizes.

[0027] During the feeding process, the plastic granules that need to be salted are fed into the cloth cylinder 22 through the feeding hopper 21. The cloth screw shaft 24 in the cloth cylinder 22 is driven to rotate by the cloth drive motor 23. Then the cloth screw shaft 24 pushes the plastic evenly in the cloth cylinder 22, and the plastic granules are evenly discharged from the straight discharge nozzle 25.

[0028] In one embodiment of this utility model, such as Figures 1-3 As shown, baffles 13 are provided on both the first conveyor belt 12 and the second conveyor belt 42 to ensure uniform transfer of plastic and reduce the slippage of plastic particles from the conveyor belts. A first fan 14 is provided above the first conveyor belt 12, and a second fan 41 is provided above the second conveyor belt 42, for drying the plastic particles after salt separation.

[0029] In one embodiment of this utility model, such as Figures 1-3 As shown, a sediment discharge mechanism 6 is provided at the bottom of the salt separation tank 5, including a sedimentation tank 63 and a scraping spiral shaft 64. The sedimentation tank 63 is located at the bottom of the salt separation tank 5, and the scraping spiral shaft 64 is installed inside the sedimentation tank 63.

[0030] A reducer 62 is installed on the outside of the sedimentation tank 63. The output shaft of the reducer 62 is connected to one end of the scraper screw shaft 64. A scraper shaft drive motor 61 is installed at the power input end of the reducer 62. A discharge valve 65 is installed at the output end of the sedimentation tank 63.

[0031] Specifically, as the sediment in the brine gradually falls into the sedimentation tank 63, and the sediment in the sedimentation tank 63 is cleaned periodically, the scraper shaft drive motor 61 drives the reducer 62 to rotate, and the reducer 62 drives the scraper screw shaft 64 to rotate, gradually transferring the sediment in the sedimentation tank 63 to the right, and finally opening the discharge valve 65 to discharge the sediment.

[0032] To clearly illustrate the above embodiments, refer to Figures 1-3 The working principle of the waste plastic particle salt separation tank device of this utility model is as follows: When in use, the salt solution is first injected into the salt separation tank 5. The plastic particles to be salted are fed into the cloth cylinder 22 through the feeding hopper 21. Then the cloth screw shaft 24 pushes the plastic evenly in the cloth cylinder 22. The plastic particles are evenly discharged from the straight discharge nozzle 25 to the salt separation tank 5.

[0033] After the plastic particles enter the brine, the denser plastics gradually fall and land on the inclined second conveyor belt 42 at the bottom of the salt separation tank 5. The second conveyor belt 42 gradually transfers the floating plastics out. As the floating plastics accumulate on the surface of the brine, they enter the inclined first conveyor belt 12 and are gradually transferred upwards. Because the feeding mechanism 2 is located between the partition 31 and the first conveyor belt 12, it effectively prevents the floating plastics from entering the right side of the partition 31 and from mixing onto the second conveyor belt 42.

[0034] During the transfer of floating plastic and bottom plastic, the plastic particles after salt separation are dried by the first blower 14 and the second blower 41. During the plastic transfer process, the brine passes through the mesh first conveyor belt 12 and the second conveyor belt 42, and flows back to the salt separation tank 5 through the first return plate 11 and the second return plate 43 to reduce brine overflow.

[0035] Finally, the sediment in the brine gradually falls into the sedimentation tank 63. When the sediment in the sedimentation tank 63 is cleaned periodically, the reducer 62 drives the scraper screw shaft 64 to rotate, gradually transferring the sediment in the sedimentation tank 63 to the right, and finally the sediment is discharged through the discharge valve 65.

[0036] In summary, the waste plastic pellet salt separation tank device of this utility model embodiment, by setting two inclined conveyor belts in the salt separation tank 5, with the feed end of the first conveyor belt 12 located above the feed end of the second conveyor belt 42, the first conveyor belt 12 transfers the plastic floating on the top of the salt solution, and the second conveyor belt 42 transfers the plastic at the bottom of the salt solution, which facilitates the separate discharge of floating plastic and bottom plastic during the salt separation process. During the plastic transfer process, the salt solution passes through the mesh-like first conveyor belt 12 and second conveyor belt 42, and flows back into the salt separation tank 5 through the first return plate 11 and the second return plate 43, reducing the overflow of salt solution.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
