Description

Technical Field

[0001] The utility model relates to the field of material drying devices, in particular to a material drying device with no dead angle for processing engineering plastics. Background Art

[0002] Plastic pellets refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Plastic pellets are the raw materials for various plastic products. For example, in the production process of plastic bags, the raw material pellets need to be cleaned, dehydrated, dried, melted, and then processed into plastic bags through extrusion and other methods. Plastic pellet dryer is an important equipment in the production process of plastic products.

[0003] After searching, a plastic particle drying device with a publication number of CN201620803588.9 specifically discloses a shell including a cylinder, the shell is installed on a vibration table, the hot air inlet is located at the bottom of the left side of the shell, the feeding hopper and the exhaust port are located at the top of the shell, and a cloth plate, a water receiving tray, at least four sieve plates and a receiving plate are arranged in sequence from top to bottom inside the shell, the cloth plate, the sieve plate and the receiving plate are composed of a skeleton and a mesh cloth wrapped on the skeleton, a connecting pipe is fixed at the vertical center position of the cloth plate and the water receiving tray so that the area above the cloth plate and the area below the water receiving tray are connected, and 1 to 5 discharge holes are evenly arranged on each sieve plate, the receiving plate is obliquely installed on the inner side of the bottom of the shell, and the discharge port is located at the lower right side of the shell and is flush with the lowest inclination of the receiving plate. The utility model provides a plastic particle drying device with a simple structure, which uses vibration dispersion to keep the plastic particles in a dispersed state, which is beneficial to the drying process.

[0004] However, the above device still has certain defects. For example, it is difficult for the above plastic dryer to continuously turn the plastic particles during the drying process, so that the piled-up plastic particles cannot be fully dried, resulting in poor drying effect. In addition, the steam generated during the drying process will accumulate in the drying box and is difficult to dissipate, resulting in low plastic drying efficiency.

[0005] Therefore, it is necessary to invent a non-dead-angle baking device for engineering plastic processing to solve the above problems. Utility Model Content
