Abstract
The present invention provided a new heating-crystallizing device which can avoid various kinds of problems such as clogging generated in a conventional case for which a screen separator is adopted, and always can feed a uniform and stable chip. This heating-crystallizing device for the thermoplastic polymer chip has a throw-in port for pellets prior to the crystallization at the upper section of a cylindrical tank, has a discharging port for the already crystallized pellets on the bottom section, and has a stirring blade group in multiple stages in the vertical direction inside. A partitioning wall made of a metal sheet which has a funnel shape is fitted in the bottom section of the tank, and a space which surrounds the partitioning wall is formed in a space between the bottom wall of the tank and the partitioning wall. Then, a hot air-feeding device which feeds hot air into the space is connected with the tank. At the same time, a feeding out pipe which feeds out the already crystallized pellets to the discharging port is connected with a deep section of the partitioning wall. On the wall surface of the feeding out pipe, a bottom side mesh section having numerous pores, which places the inside of the feeding out pipe and the space under a communicated state, is provided. In addition, a hot air-blowing out port which opens to the inside of the cylindrical body wall of the tank while continuing from the upper edge of the space is provided. Also, on the opened surface of the hot air- blowing out port, a body side mesh section having numerous pores, which places the inside of the hot air-blowing out port and the inside of the tank under a communicated state, is provided.
Description
Technical field
The present invention relates to a kind of heating crystallization apparatus that thermoplastically polymer fragments such as polymeric amide, polyester make its crystallization that heats, particularly relate to the heating crystallization apparatus that a kind of preheating or heating polyester fragment carry out pre-crystallization.
Background technology
When thermoplastically polymer fragments such as the polymeric amide by the no crystallization of formation such as the smear metal behind melt polymerization surface, polyester were carried out drying or solid state polymerization operation, when being heated to common 90 ℃ during to the temperature more than 130 ℃, fusion mutually took place in fragment.This fusion has the situation of the same bulk of piece that formation forms from 2～3 fragments and even stone, in either case, all can cause fault in subsequent handling, is bad.
In the past, in order to eliminate such fusion phenomenon, the inventor had proposed to be equipped with the heating crystallization apparatus (No. 3050004, login utility model communique) of the agitating wing with conical screen separators in the bottom.This heating crystallization apparatus has mutual interfused effect does not take place between the fragment of guaranteeing, is widely used.
But, in this heating crystallization apparatus, have following problem.
1. the treated side of screen separators tilts, and causes obstruction easily.
2. in the maintenance of the screen separators of stopping up, must carry out great operations such as large-scale operation splitting.
3. because along with the aggravation heat that stops up (solidifying) is not enough gradually, so the treatment time must be elongated gradually.
4. since as 3. heat deficiency gradually, thereby be difficult to grasp the bad time of origin of crystallization, cause uncertain fault thus easily.
5. owing to as 4., be easy to cause uncertain fault, use continuously in intermittently mode not so be far from being.
Summary of the invention
The purpose of this invention is to provide and a kind ofly new taked the heating crystallization apparatus of the thermoplastic polymer fragment of certain measure for solving above-mentioned each problem.
To achieve these goals, the heating crystallization apparatus of thermoplastic polymer fragment of the present invention, it is the particle input port before tubular jar top has crystallization, particle relief outlet after the bottom has crystallization, and the thermoplastically polymer fragment heating crystallization apparatus that has multistage agitating wing group in inside along the vertical direction, wherein, in the bottom of jar, be equipped with and be the partition wall that funnel shaped metal sheet is made, between the diapire of this jar and partition wall, be formed with space around this partition wall, when the hot-air supplying equipment that will be used in this space the supply hot blast is connected on the jar, send pipe at the particulate that the depths of partition wall is connected with after above-mentioned relief outlet is sent crystallization, this wall of sending pipe is provided with has a plurality of bottom sieve aperture portions that are used to make the inner and above-mentioned space of this pipe to form the aperture of connected state, also be provided with in addition and be connected with above-mentioned spatial upper limb and at the hot air blow port of the inboard opening of tubular body wall of jar, the opening surface of this hot air blow port is provided with has a plurality of inner and jar inner main part sieve aperture portions that form the aperture of connected state of this blow-off outlet that are used to make, and, be useful on the open of this main part sieve aperture portion of maintenance with lid in the arranged outside of this main part sieve aperture portion.
Therefore, adopt the present invention, can fully avoid the variety of issue that in the example of the prior art that adopts above-mentioned screen separators, produces, can provide can all-the-time stable ground supply fragment the heating crystallization apparatus.And then, owing to be difficult for to produce stop up,, therefore,, obtained great effect improving operating efficiency and guaranteeing secure context so running that needn't stop gear can significantly reduce the clearing times to jar inside.And, can easily keep in repair by opening to open with lid, easy to use.
