Description

Technical Field

[0001] This utility model relates to the field of polyester chip drying technology, specifically to a novel polyester chip blower dryer. Background Technology

[0002] Polyester raw materials obtained from polymerization are generally processed into sheet-like granules of approximately 4*5*2 mm, commonly known as polyester chips. As a raw material, they are mainly used in fibers, various containers, packaging materials, films, sheets, engineering plastics, and other fields. Based on properties, they can be classified as: colored, flame-retardant, antistatic, moisture-absorbing, anti-pilling, antibacterial, whitening, low-melting-point, and high-tack polyester chips; based on applications, they can be classified as: fiber-grade polyester chips, bottle-grade polyester chips, and film-grade polyester chips. Fiber-grade polyester chips can be further classified according to the content of the matting agent TiO2: ultra-glossy, glossy, semi-glossy, and matte polyester chips. There are also cationic polyester chips.

[0003] When hydrated polyester chips melt, they hydrolyze, causing a decrease in molecular weight and affecting the quality of the filaments. Therefore, the material needs to be dried. However, the existing drying process for polyester chips is not very effective, resulting in incomplete drying and low drying efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a novel polyester chip blower dryer to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A novel polyester chip blower dryer includes a frame and a drying chamber located on top of the frame. A shell is provided on one side of the drying chamber, and a blower for blowing air into the shell is provided on the other side. The shell is a cavity structure with openings on both sides and is connected to the drying chamber. A connecting plate is provided inside the shell and on one side of the blower. Several sets of ducts extending into the drying chamber are provided on the openings of the connecting plate. A heating plate is provided on the side of the connecting plate away from the duct sets. A material tray is provided inside the drying chamber and on one side of the duct sets.

[0008] Preferably, the bottom of the material tray is inclined, and a discharge pipe is provided at the inclined position, and a solenoid valve is provided on the discharge pipe.

[0009] Preferably, the drying chamber has an inlet pipe on one side for feeding the material tray, and a discharge pipe for discharging material is provided below the material tray in the drying chamber.

[0010] Preferably, the number of material trays is three sets, and the drying chamber is provided with a rotating shaft that passes through the material trays and the discharge pipe.

[0011] Preferably, the top of the frame is provided with a drive motor for driving the rotating shaft to rotate, and the rotating shaft is movably connected to the drying oven through bearings.

[0012] Preferably, the number of catheter groups is three, and the catheter groups located in the upper and lower positions are inclined.

[0013] The beneficial effects of this utility model are as follows: By setting up a heating plate and a blower, the blower blows hot air towards the guide tube assembly, which then guides the air into the various material trays inside the drying chamber. The drive motor drives the rotating shaft to rotate, which in turn drives the material trays to rotate, thus achieving cyclic heating of the polyester chips in the material trays. After drying, the electronic valve is opened, and the chips fall through the discharge pipe and are discharged outwards, thereby completing the drying process of the polyester chips. This reduces the probability of the polyester chips sticking together in subsequent production processes and improves the finished product quality of the polyester chips. Attached Figure Description
