A dryer for producing nylon plastic particles

Abstract

This utility model discloses a dryer for the production of nylon plastic particles, applicable in the field of plastic production. It includes a housing with supporting legs bolted to the bottom. The dryer heats air through a heating mechanism; hot air enters the rotating tube from the fixed shell, then enters the hollow spiral blades and stirring rod, heating the spiral blades and spraying out from the air holes of the stirring rod. A drive mechanism rotates the hollow spiral blades and stirring rod to dry the particles, achieving high drying efficiency, saving drying time, and improving production efficiency. Furthermore, the dryer facilitates maintenance by moving a movable block to move a locking rod, disengaging it from the locking hole. A fixed rod, under the action of a second spring, disengages from the fixed groove, allowing the cover plate to be removed for maintenance. This reduces workload and improves maintenance efficiency.

Description

Technical Field

[0001] This utility model relates to the field of plastic production, and in particular to a dryer for the production of nylon plastic particles. Background Technology

[0002] A search of Chinese patents revealed publication number CN210758601U, which discloses a plastic granule drying device. This device, belonging to the field of drying equipment, addresses the lack of a comprehensive drying device in the prior art that integrates wind and heat drying. Given the light weight of the plastic granules, wind is used to separate water from the granules, and a heater further assists in heating to ensure complete evaporation of moisture. It mainly includes a frame, a drying tank mounted on the frame, support legs, and a motor. The drying tank is connected to a feeding hopper, and a lower discharge pipe is located at the bottom of the drying tank. A stirring fan is located at the connection between the drying tank and the feeding hopper. The drying tank contains a heater and a large fan, with a screen above the fan. An upper discharge pipe is also located on the drying tank, connected to a lower discharge pipe. A door panel is located between the lower discharge pipe and the drying tank. A small fan is located below the heater. A water outlet is located at the bottom of the drying tank. This invention is primarily used for drying plastic granules.

[0003] Existing dryers have low drying efficiency. Generally, when drying plastic particles, the particles are placed inside the drying device, piled up, and then heated for drying. The drying speed inside and outside the plastic particles is different, affecting the drying efficiency and production efficiency. It is also inconvenient to maintain. When maintaining the inside of the drying device, it is necessary to open the cover plate, which is usually fixed with multiple bolts. During maintenance, tools are needed to disassemble and reassemble the bolts, which is a troublesome process, increases the workload, and reduces the maintenance efficiency. In order to solve the above problems, we propose a dryer for the production of nylon plastic particles. Utility Model Content
