Description
Technical field
The present invention relates to a kind of novel pre-crystallizer, belong to and spin preceding drying equipment technical field.
Background technology
Pre-crystallizer is mainly used in the preparatory Crystallization Procedure of PET, makes section keep small relative motion, improves its melt temperature; To prevent section knot knot, for road, back high temperature drying creates favorable conditions, it has the material of passing; Carry out heat exchange on the way, constantly take away moisture, remove the surface adsorption water of considerable part; Make section produce certain degree of crystallinity, accomplish high efficiency preparatory crystallizing and drying technology.Crystallization can be carried out in common drying box in advance, also can in being similar to the mechanical type drying machine of high-speed mixer, carry out.When in common drying box, carrying out preparatory crystallization; Should be noted that and to think that when the polymer chips devitrification preparatory crystallization process finishes; The shortcoming of the method is that preparatory crystallization is insufficient or excessive; The complete degree of leaning on the preparatory crystallization of artificial naked-eye observation, subjective error is too big, influences the quality of preparatory crystallization section.Use is similar to the preparatory crystallization of mechanical type drying machine of high-speed mixer, is to rely on mechanical friction that material is heated up, and this method programming rate is fast, and is also comparatively favourable to the volatilization of moisture content, but can only be used for small-sized discontinuous production.For the bigger enterprise of scale, the raw material that around-the-clock production needs is just many, therefore need a kind ofly can carry out continuously crystallization in advance also than the pre-crystallizer that is easier to the crystallization control degree.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide and a kind ofly be not only applicable to midget plant, also can bear the novel pre-crystallizer Large Scale and Continuous operation, relatively simple for structure.
For realizing above-mentioned purpose, the technical solution that the present invention adopted is: a kind of novel pre-crystallizer, and integral body is stainless steel rounding drum ladle; Employing transparent high temperature resistant tempering glass in right side becomes, and the section inlet is located at the upper left side of pre-crystallizer wall, below section enters the mouth a striker plate and two fender plates is set; Two fender plate secured in parallel are provided with one and leak flitch in the wall left side between two fender plates, leak an orifice plate to be set below the flitch; Two fender plate left sides connect a circular hot-air channel, and the hot-air channel opposite side connects an air-heater, and gas vent is set in the middle of the pre-crystallizer wall top; Gas vent set inside tapered cap; The pre-crystallizer lower right is provided with the section outlet, and left side of face is provided with circular air channel under orifice plate, and circular air channel connects pulse air flow generator; The right side is provided with a powerful hot-flow flue, and powerful hot-flow flue connects a powerful air-heater.
Said striker plate becomes counterclockwise 60 ~ 90 ° of angles with horizontal plane, the angle of regulation range of fender plate is to become 30 ~ 75 ° of angles counterclockwise with horizontal plane, and striker plate and aperture all is set above the fender plate, and the aperture is less than 2mm.
Parallel distance is 10 ~ 20cm between said two fender plates.
On the said tapered cap aperture is set, the aperture is less than 2mm.
Aperture on the said leakage flitch is 1 ~ 3mm, and the aperture on the orifice plate is less than 2mm.
The operation principle of said small-sized pre-crystallizer is: the air-heater of at first opening pulse air flow generator and left side; To need the section of preparatory crystallization to drop into pre-crystallizer then from the section inlet; Section along striker plate and above fender plate fall into Lou on the flitch; Section receives the effect of the hot blast that hot blast that air-heater blows and pulse air flow generator send simultaneously and constantly upwards seethes and push ahead, and the aperture that in progradation, sees through on the leakage flitch falls on the orifice plate, and the effect of the hot blast that hot blast that the section on the orifice plate blows at air-heater again and pulse air flow generator send is constantly upwards seethed and pushed ahead; Simultaneously; Powerful air-heater is blown into powerful hot blast in pre-crystallizer in the time of setting, make chip drying more even, and crystallization reaches re-set target.
Beneficial effect of the present invention: the effect of the striker plate at charging aperture place is to prevent to cut into slices back-mixing and blown to the porch by hot blast, can control the porch simultaneously and leak the slice thickness on the flitch; The effect of fender plate is the inlet section to be imported orifice plate avoid section the dead angle to occur in the porch; The tapered cap that air outlet goes out has prevented seething outside the container that flies out owing to what cut into slices in the crystallization process in advance; Section in the pre-crystallizer receives the hot blast effect of both direction constantly to seethe preparatory crystallization and constantly push ahead simultaneously, under the effect of powerful hot blast, makes drying and crystallization more abundant, and then makes continuous production be able to carry out.
