Abstract
The utility model, which belongs to, concentrates feeding system technical field, it is related to a kind of agitating paddle for concentrating feeding system crystallizer, including central axis and several paddles being distributed on the central axis, several spreaders are additionally provided on the central axis, it is less than the bottom outer diameter of the spreader under in the bottom outer diameter of upper spreader, the lower part of the central axis is equipped with deflection cone.The utility model allows the periphery of the material of whereabouts toward crystallizer to be shed by spreader and deflection cone, keeps distribution of the material in bucket more reasonable, and decline uniformly, obtains same drying time, avoids the generation of agglomeration.
Description
Technical field
The utility model relates to concentrate feeding system technical field, in particular to a kind of concentration feeding system crystallizer
Agitating paddle.
Background technique
Crystallizer is mainly for the PET material in plastic material.PET is hygroscopic materials, if moisture content is too high, in high temperature
Hydrolysis can be generated under processing, PET molecular chain rupture and thermal decomposition is made to generate acetaldehyde, physical property and engineering properties reduce, crystalline rate
Accelerate, bottle embryo partially crystallizable albefaction can be made when bottle embryo projects, influence the quality of product.Before bottle embryo ejection formation, PET
It must first dry to moisture content in 0.005% (50ppm) hereinafter, so can just produce good noncrystalline transparent bottle embryo.PET
Characteristic determine that it cannot complete to carry out regeneration use by common granulation mode, it is necessary to by it is special recrystallization just may be used
It uses, noncrystalline PET contact high temperature bonds, and the main purpose of crystallization is that bonding is generated when preventing PET high temperature drying, commonly uses
Increase stirring action while method is using drying or so that PET is boiled with air-flow, temperature continues to increase, and when reaching 120 DEG C, has
Multiple strands of intermolecular interaction carry out local rearrangement, produce spheroidal cementite, that is, crystallize, the maximum crystallization journey of PET
Degree about 55%, can produce orderly crystal region.
In subsequent use and client feedback there arises a problem that 1, due to the pyramidal structure of ladle body, cause intermediate
Material declines fast, and the decline of the material of ladle body two sides is slowly, and drying time one is easy to cause agglomeration for a long time.2, circular cone position and
Feed opening can not be stirred effectively, and regular agglomeration is caused.
It is therefore necessary to improve stirring paddle structure to solve problem above.
Utility model content
The main purpose of the utility model is to provide a kind of agitating paddles for concentrating feeding system crystallizer, can be avoided
Material agglomeration.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of stirring for concentrating feeding system crystallizer
Paddle is additionally provided with several spreaders on the central axis including central axis and several paddles being distributed on the central axis,
On the bottom outer diameter of spreader be less than the bottom outer diameter of spreader under.
Specifically, the paddle has the inclination angle in opposite 10 ° of central axis face.
Further, the paddle has knife-edge structure.
Specifically, the side of the deflection cone is equipped with triangle paddle.
Specifically, the bottom of the central axis is equipped with round steel.
By adopting the above technical scheme, the beneficial effect of technical solutions of the utility model is:
The utility model allows the periphery of the material of whereabouts toward crystallizer to be shed by spreader, makes point of the material in bucket
With more rationally, decline uniformly, obtains same drying time, avoids the generation of agglomeration.
Detailed description of the invention
Fig. 1 is the cross-sectional view of embodiment crystallizer；
Fig. 2 is the perspective view of agitating paddle.
Digital representation in figure:
1- central axis, 11- paddle, the upper spreader of 12a-, spreader under 12b-, 13- deflection cone, the stirring of 14- triangle
Leaf, 15- round steel；
2- crystallizing tank, 21- bell mouth.
Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
Embodiment:
As depicted in figs. 1 and 2, the agitating paddle of a kind of concentration feeding system crystallizer of the utility model, including center
Axis 1 and several paddles 11 being distributed on central axis 1 are additionally provided with several spreader 12a, 12b, upper spreader on central axis 1
The bottom outer diameter of 12a is less than the bottom outer diameter of lower spreader 12b, and the lower part of central axis 1 is equipped with deflection cone 13.From crystallizing tank 2
When top feeds down, the blocking that material will receive spreader 12a, 12b is shed outward, makes material in funnel shaped crystallization
Accumulation mode in bucket 2 is short in centre, and the high distribution situation in periphery, such material can be from the gap of deflection cone 13 and crystallizing tank 2
It falls on down at bell mouth 21 in the middle, the material in crystallizing tank 2 entire in this way can avoid local flow in the state of flowing
Agglomeration problems caused by unsmooth.The utility model allows the material of whereabouts toward the periphery of crystallizer by spreader and deflection cone
It sheds, keeps distribution of the material in bucket more reasonable, decline uniformly, obtains same drying time, avoids the generation of agglomeration.
As shown in Fig. 2, paddle 11 has the inclination angle in opposite 10 ° of central axis face.Paddle 11 is in rotation in this way
When can inswept certain altitude, so that material is preferably broken up, avoid agglomerating.
As shown in Fig. 2, paddle 11 has knife-edge structure.The reaction force that is subject to when rotation of paddle 11 in this way
It is small, it smashes material and is easier.
As depicted in figs. 1 and 2, the side of deflection cone 13 is equipped with triangle paddle 14.Deflection cone 13 is to be located at crystallizing tank 1
The channel of tapered part, material decline is reduced, can be by the material in 13 outside of deflection cone using triangle paddle 14
It breaks up, material is facilitated to continue flow down by gap.
As depicted in figs. 1 and 2, the bottom of central axis 1 is equipped with round steel 15.Material has to pass through before through bell mouth 21 and leads
The lower part of flow cone 13, is also easier to generate material here and is difficult to the dead zone flowed, can will be in bell mouth 21 using round steel 15
The material of side is smashed, thus can smooth discharging.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
