Description

Terylene pre-crystallizer

Technical field

The present invention relates to a kind of terylene pre-crystallizer.

Background technology

Terylene chips raw material needs polyester raw material to carry out pre-crystallized place before pushing entering extruderReason, the main purpose of pre-crystallized processing is the softening point in order to improve section, removes moisture, makes the raw material of cutting into slicesGrain grain separately, can make material even while improving follow-up extruding.

Traditional pre-crystallizer is carrying out mainly there is following defect when pre-crystallized to section raw material;

The section raw material that is positioned at drying box mainly relies on the hot gas passing into dry, and passes through pulse motorProvide impulse force that raw material is discharged from section outlet, because the hole on the sieve plate in drying box is in the past vertical setting, when the wind-force therefore providing when pulse motor outwards blows out section raw material, the raw material of need to cutting into slices only can doMove up and down, material is difficult to drain smoothly in section outlet; In brief, the sieve plate of vertical core structure is unfavorable forMaterial is discharged, can make partial material repeatedly fully dry in drying box, cause section to be dried excessivelyPhenomenon, occur that moisture is on the low side.

Summary of the invention

The technical problem to be solved in the present invention is: a kind of terylene pre-crystallizer is provided, solves pre-crystallizer in the pastThe defect that the raw material that is unfavorable for cutting into slices is discharged.

The technical solution adopted for the present invention to solve the technical problems is: a kind of terylene pre-crystallizer, comprises dryDry casing, arranges section entrance in a side upper end of drying box, arranges in the opposite side lower end of drying boxHave section outlet, the base plate of described drying box adopts sieve plate to make, and the sieve aperture on this sieve plate goes out towards otchMouth one side is inclined to set;

Be provided with for the heating pipe by hot gas in drying box, described heat in the bottom of drying boxIn tracheae, be provided with multiple pulse blower fans, heating pipe entirety is inclined to set and its incline direction and sieve apertureIncline direction consistent; Top at described drying box is provided with heat outlet.

Further, described heating pipe comprises straight length and Taper Pipe section, and described straight length is through Taper Pipe sectionBe connected with the bottom of drying box, described pulse blower fan is arranged in the inner chamber of Taper Pipe section. Pulse blower fanThe wind-force providing can act directly on sieve plate, avoids the flow loss of wind-force in heating pipe.

Further, be positioned on the both sides drying box inwall of sieve plate top and be provided with some points of material strips, instituteThe cross section of point material strip of stating is prismatic structure, and each point of material strip tilts and be arranged on drying box at widthIn body, the angle of inclination of each point of material strip is consistent with the angle of inclination of sieve aperture. The existence of point material strip be mainly forBe that section raw material can separate by grain grain in the time being discharged from, prevent that the phenomenon of raw material caking from occurring.

Further, the tapered body structure of upper wall spirogyrate of described drying box, described heat outletBe positioned at the top of bullet. The bullet structure forming by upper wall evagination, can guarantee that section has enoughSpace, strikes above the upper wall of drying box while avoiding section to fly out in drying box.

Further, be positioned at drying box section exit and be provided with the adjustment plate for adjusting thickness of feed layer.By adjusting the gradient of this adjustment plate, thereby it is how many to control the piled up bed of material.

The invention has the beneficial effects as follows: by changing the structure of heating pipe and sieve aperture, thereby change section raw materialMovement locus in the time being blown, thus the efficiency of pre-crystallizer in the time that raw material is discharged improved, avoid raw material long-pendingThe phenomenon of staying occurs.

Detailed description of the invention

As shown in Figure 1, a kind of terylene pre-crystallizer, comprises drying box 1, in a side of drying box 1End arranges section entrance 2, is provided with section outlet 3, drying box 1 in the opposite side lower end of drying box 1Base plate adopt sieve plate 6 make, the sieve aperture 61 on this sieve plate 6 exports a side towards otch and is inclined to set.

Be provided with in the bottom of drying box 1 in drying box 1 by the heating pipe of hot gas, hot gasIn pipe, be provided with 2 pulse blower fans 7, heating pipe entirety is inclined to set and its incline direction and sieve aperture61 incline direction is consistent; Be provided with heat outlet 5 at the top of drying box 1.

Heating pipe comprises straight length 41 and Taper Pipe section 42, and straight length 41 is through Taper Pipe section 42 and drying box 1Bottom connect, described pulse blower fan 7 is arranged in the inner chamber of Taper Pipe section 42. Providing of pulse blower fan 7Wind-force can act directly on sieve plate 6, avoid the flow loss of wind-force in heating pipe.

Be positioned on both sides drying box 1 inwall of sieve plate 6 tops and be provided with some points of material strips 8, point material strip 8Cross section be prismatic structure, and each point of material strip 8 tilt and be arranged in drying box 1 at width,The angle of inclination of each point of material strip 8 is consistent with the angle of inclination of sieve aperture 61. The existence of point material strip 8 be mainly forBe that section raw material can separate by grain grain in the time being discharged from, prevent that the phenomenon of raw material caking from occurring.

The tapered body structure of upper wall spirogyrate of drying box 1, heat outlet 5 is positioned at the top of bullet.The bullet structure forming by upper wall evagination, can guarantee that section has enough spaces, avoids sectionWhile flying out in drying box 1, strike above the upper wall of drying box 1.

Being positioned at drying box 1 section exports 3 places and is provided with the adjustment plate 9 for adjusting thickness of feed layer. Pass throughAdjust the gradient of this adjustment plate 9, thereby it is how many to control the piled up bed of material.

Section raw material is by after in drying box 1, hot gas inlet pipe passes into hot blast, in drying box 1Raw material is dried, after the time to be dried arrives, and starting impulse motor 7, the wind-force that pulse motor 7 provides is by formerMaterial blows out, and as shown in Figure 2, by changing the structure of heating pipe setting position and sieve aperture 61, cuts thereby changeThe movement locus of tablet raw material in the time being blown, thus the efficiency of pre-crystallizer in the time that raw material is discharged improved, avoidThe phenomenon that raw material accumulates occurs.

More than describe preferred embodiment of the present invention in detail. Should be appreciated that the ordinary skill of this areaPersonnel just can design according to the present invention make many modifications and variations without creative work. Therefore, allIn the art technical staff under this invention's idea on the basis of existing technology by logic analysis, push awayReason or the limited available technical scheme of experiment, all should fall within the scope of protection of the present invention.
