Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle drying and screening, in particular to a plastic particle drying and screening integrated machine. Background Art

[0002] With the development of economy, plastic products have become an indispensable part of daily life, and the number of plastic products discarded every day in the world has reached an astronomical figure. At present, the recycling and reuse of plastic products has become a considerable market.

[0003] The common vibration screening equipment on the market can only be used to grade and screen materials by size, but not by length, due to the limitation of its own structure. For example, in the production process of plastics, some long pellets are often produced. These pellets are usually unqualified and have a great adverse effect on the subsequent plastic production. Therefore, these long pellets must be screened out.

[0004] Plastic products will generate a lot of heat when granulating. After cooling in a water tank, they are cut and then screened. At this time, the screened materials contain moisture, which has a certain impact on the screening of the materials. Therefore, they need to be dried in a dryer first and then screened with a screening machine. This not only increases the operation time, but also increases the cost of the equipment, resulting in a decrease in production efficiency. In view of the above problems, a plastic granule drying and screening integrated machine is proposed. Utility Model Content

[0021] See also Figure 1-5 The utility model provides a technical solution: a plastic particle drying and screening integrated machine, comprising a sieve body 7 and a drying sieve plate 4. The drying sieve plate 4 is installed in the sieve body 7. A sealing gasket 14 is arranged between the lower end of the drying sieve plate 4 and the sieve body 7. The drying sieve plate 4 is divided into two sections. A section on the left side of the drying sieve plate 4 is arranged as a blind plate 41. When the material passes through the blind plate 41, the material can be effectively spread out, so that the material is dispersed and evenly enters the slit sieve plate 42. A section on the right side of the drying sieve plate 4 is arranged as a slit sieve plate 42. The aperture of the slit sieve plate 42 is smaller than the smallest particle size of the material. An air distribution plate 8 is arranged directly below the slit sieve plate 42. A hot air chamber 17 connected to the drying sieve plate 4 is arranged below the air distribution plate 8. A hot air inlet 10 is arranged on the side of the hot air chamber 17. The hot air enters the hot air chamber 17 through the hot air inlet 10. Under the action of the air distribution plate 8, the hot air can be evenly blown on the slit sieve plate 42. The hot air passes through the slit When the sieve plate 42 is blown onto the material, the material can be effectively air-dried. An upper sieve plate 5 is arranged in the sieve body 7 on the right side of the drying sieve plate 4. A climbing plate 15 is arranged between the right end of the slit sieve plate 42 and the upper sieve plate 5. This climbing plate 15 can block the material and increase the time for the material to stay on the drying sieve plate 4, so that the material can be dried more fully. A lower sieve plate 6 is arranged below the upper sieve plate 5. The aperture of the upper sieve plate 5 is larger than that of the lower sieve plate 6. The upper sieve plate 5 is mainly responsible for removing the connected or uncut large particles in the material. The finished material falls on the lower sieve plate 6 after passing through the upper sieve plate 5. The lower sieve plate 6 is mainly responsible for removing smaller impurities in the material. Then the three kinds of materials are discharged through the discharging port 9. A discharging port 9 is arranged below the right end of the sieve body 7. The discharging port 9 is set to three, and the discharging ports 9 correspond to the upper sieve plate 5, the lower sieve plate 6 and the lower sieve plate 6, respectively.

[0022] The top of the drying screen plate 4 is provided with an upper cover Ⅰ1, a dust cover 2, and an upper cover Ⅱ3 from left to right. The upper cover Ⅰ1 corresponds to the blind plate 41, and a feed port is provided on the upper cover Ⅰ1. The dust cover 2 corresponds to the slit screen plate 42. A hot air outlet 16 is provided on the top of the dust cover 2. The upper cover Ⅱ3 corresponds to the upper sieve plate 5, and an inspection door 18 is provided on the upper cover Ⅱ3. A spiral compression spring 11 is provided between the sieve body 7 and the bracket 12, and vibration motors 13 are provided on both sides of the sieve body 7.

[0023] During use: after the material passes through the feed port of the upper cover Ⅰ1, it falls on the blind plate 41. When the material passes through the blind plate 41, the material can be effectively spread flat, and the hot air enters the equipment through the hot air inlet 10. After the hot air passes through the air balancing plate 8, the hot air can be evenly blown on the slit screen plate 42 under the action of the air balancing plate 8. The hot air passes through the slit screen plate 42 and blows onto the material, which can effectively dry the material. After the hot air blows through the material, it is collected and discharged under the action of the dust removal hood 2. The dried material will pass through a small climbing plate 15 at the end of the slit screen plate 42. This climbing plate 15 can block the material so that the material can be dried more fully. After climbing, the material will fall on the upper screen plate 5. The upper screen plate 5 is mainly responsible for removing the connected or uncut large particles in the material. The finished material passes through the upper screen plate 5 and falls on the lower screen plate 6. The lower screen plate 6 is mainly responsible for removing smaller impurities in the material. Then the three materials at the screening position are discharged through the discharge port 9.
