Problems solved by technology
[0002] Polyester chips are a raw material for producing colored filaments, which need to be dried before being made into colored filaments. The existing drying devices for polyester chips include drying towers, but there are many existing drying towers. Insufficient, the drying time is long, and continuous production is not possible; the moisture content of the slices does not meet the specified requirements, and the quality is uneven; and the output is not high, and the energy consumption is high

Embodiment Construction
[0021] In the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connected, or integrally connected; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention based on specific situations.
[0022] Such as figure 1 As shown, a drying tower for polyester chips includes a drying tower shell, the drying tower shell includes a conical shell at the bottom, a first cylindrical shell and a second column that are arranged on the upper part of the conical shell shaped shell, the third cylindrical shell, the first cylindri...

The invention discloses a drying tower for polyester chips. The drying tower for the polyester chips comprises a drying tower shell. The drying tower shell comprises a conical shell, a first cylindrical shell, a second cylindrical shell, a third cylindrical shell, a first short shell and a second short shell. Nitrogen distributors are arranged on the first short shell and the second short shell. Two material barrier cones are arranged on the inner wall of the first cylindrical shell and the inner wall of the conical shell correspondingly. The chips are immediately completely surrounded by hotnitrogen after entering the drying tower, adhesion cannot happen, the chips cannot be broken in the drying process, no powder can be generated in the drying process, the temperature difference in thedrying tower is almost zero, the crystallinity of the chips is quite uniform, and the drying effect is good. Accurate feeding operation of a drying machine is achieved, the yield adjustment can be quite easy, and material level continuous adjustment can be quite conveniently conducted. The drying tower for the polyester chips is reasonable in structural design and easy and convenient to operate, saves energy, is efficient, is free of operation parts, and is high in reliability and low in routine repair and maintenance cost.
Description
technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a drying tower for polyester chips. Background technique [0002] Polyester chips are a raw material for producing colored filaments, which need to be dried before being made into colored filaments. The existing drying devices for polyester chips include drying towers, but there are many existing drying towers. Insufficient, the drying time is long, and continuous production is not possible; the moisture content of the slices does not meet the specified requirements, and the quality is uneven; and the output is not high, and the energy consumption is high. Contents of the invention [0003] The object of the present invention is to provide a drying tower for polyester chips aiming at the deficiencies of the prior art. [0004] The technical solution of the present invention to solve the above problems is: a drying tower for polyester chips, including a drying tower ...
