Charging barrel of infrared dehumidification, crystallization and drying all-in-one machine and crystallization and drying all-in-one machine

Abstract

The invention discloses a charging barrel of an infrared dehumidification, crystallization and drying all-in-one machine and a drying machine. The cross section of the charging barrel is in the shape of a polygon with the side number larger than the side number of a pentagon; one end of the charging barrel is open and serves as a feeding end; each plate face forming the polygonal charging barrel comprises a middle plate part, a first closing-in plate part and a second closing-in plate part; the first closing-in plate part and the second closing-in plate part are arranged at the two ends of each middle plate part, form obtuse angles with each middle plate part and are closed in the middle; a discharge hole is formed in the side wall of the charging barrel or an opening in the other end of the charging barrel is set as the discharge hole; and when the opening in the other end of the charging barrel is set as the discharge hole, a spiral discharging guide plate facilitating discharging of materials is arranged in the charging barrel. According to the drying machine, the charging barrel is used, the better material turning effect can be achieved under the condition that no material turning plate exists, the machining difficulty is low, and the drying machine is suitable for crystallization and drying of plastic particles with high viscosity.

Description

technical field [0001] The invention relates to a material cylinder of an infrared dehumidification, crystallization and drying integrated machine, and also relates to an infrared dehumidification, crystallization and drying integrated machine using the material cylinder. Background technique [0002] In order to improve the quality of plastic products, their raw materials are generally processed into plastic particles. Loose plastic particles are susceptible to moisture when exposed to air. Therefore, loose plastic particles need to be dried before being processed into plastic products. The common method is to use a heat dissipation fan to directly send the heat of the heater through the pipeline into a pile of loose raw materials to dry the raw materials. The heat will diffuse in the loose raw materials, and the peripheral raw materials will be heated later, and the raw materials are in close contact with each other, which reduces the contact area between the heat and the...

[0005] 2. The rotation of the filter cartridge of the current plastic particle dryer is driven by the motor, and the filter cartridge is generally axially slid and can be pulled out from the inside of the casing, which is convenient for cleaning and maintenance. Therefore, the installation of the motor needs to be done with The filter cartridge is slid out from the inside of the casing together, and the other end of the entire plastic particle dryer needs to be installed with other electrical components such as a fan, which leads to wiring at both ends of the equipment, complicated internal wiring and potential safety hazards

[0006] 3. When the infrared light box of the current plastic particle dryer is heated, although the light tube is facing the direction of the material, the heat generated by the light tube will also be transferred to the light box, so that the plastic particles will be heated when they fall on the light box. And it adheres to the light box, which leads to serious adhesion of plastic particles on the light box
