Description

Crystallization device for polyester chips

Technical Field

The utility model relates to a sliced crystallization device of polyester.

Background

The polyester chip is a production raw material for chip spinning, and when the polyester chip is used, the polyester chip must be crystallized first, so that the moisture in the polyester chip of the production raw material is removed, the crystallinity of the chip is improved, and the purpose of improving the softening point of the chip is achieved. The prior art has a bit of deficiency: polyester slices in a crystallization system are more or less sucked by a crystallization fan and then blown out, one part of the slices are adhered to a heating pipe of a heater, the other part of the slices are blown to the bottom of a crystallization bed by wind, the more the slices at the bottom of the crystallization bed accumulate after the time is long, and the machine is required to be stopped and cleaned regularly; more serious, the slices adhered to the heating pipe of the heater can be melted and agglomerated, and can be burnt after a long time, so that the potential safety hazard is large.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a sliced crystallization device of polyester through increasing a filter, blocks that the polyester section in the tuber pipe is inhaled by crystallization fan, has effectively solved the problem pointed out among the background art.

The utility model adopts the technical proposal that:

the utility model provides a sliced crystallization device of polyester, includes the crystallization bed, the feed inlet and a wet feed bin of crystallization bed link to each other, the air outlet that passes through tuber pipe and a crystallization fan at the bottom of the tower of crystallization bed links to each other, be equipped with the heater on the tuber pipe between the crystallization fan and the crystallization bed bottom of the tower, the air outlet of crystallization bed passes through the air intake that tuber pipe and cyclone linked to each other, cyclone's air outlet passes through the air intake that tuber pipe and a filter links to each other, the air outlet of filter passes through the air intake that tuber pipe and crystallization fan and links to each other, the bottom discharge gate and a drying tower of crystallization bed link to each other.

Preferably, the filter comprises a housing, an inlet flange arranged at the air inlet of the filter and an outlet flange arranged at the air outlet of the filter, and a filter screen is arranged between the air inlet and the air outlet of the filter on the housing.

Preferably, the shell is provided with an inspection window between the filter air outlet and the filter screen, and the inspection window can be opened.

Preferably, the filter screen adopts a detachable filter screen.

Preferably, the bottom of the wet silo is provided with a rotary valve.

The utility model has the advantages that:

1. the utility model separates the polyester slices which are not separated by the cyclone separator by the filter, and prevents the polyester slices from entering the crystallization fan and adhering to the bottom of the heater and the crystallization bed;

2. the filter is provided with an inspection window, so that the accumulation condition of the polyester chips in the filter can be observed at any time, and the filter can be quickly cleaned by opening the inspection window during cleaning;

3. the filter screen is detachable and convenient to replace.

FIG. 2 is a schematic view of the filter construction;

fig. 3 is a right-view structural diagram of fig. 2.

Detailed Description

The present invention will be described in further detail with reference to the following detailed description of specific embodiments thereof, which is illustrated in the accompanying drawings.

Example 1

As shown in fig. 1-3, a crystallization device for polyester chips, comprises a crystallization bed 1, wherein a feed inlet of the crystallization bed 1 is connected with a wet storage bin 2, the bottom of the crystallization bed 1 is connected with an air outlet of a crystallization fan 3 through an air pipe, a heater 4 is arranged on the air pipe between the crystallization fan 3 and the bottom of the crystallization bed 1, the air outlet of the crystallization bed 1 is connected with an air inlet of a cyclone separator 5 through an air pipe, the air outlet of the cyclone separator 5 is connected with an air inlet of a filter 6 through an air pipe, the air outlet of the filter 6 is connected with an air inlet of the crystallization fan 3 through an air pipe, and a discharge outlet at the bottom of the crystallization bed 1 is connected with a drying tower 7.

The filter 6 comprises a shell 61, an inlet flange 62 arranged at the air inlet of the filter 6 and an outlet flange 63 arranged at the air outlet of the filter 6, wherein a filter screen 64 is arranged between the air inlet and the air outlet of the filter 6 on the shell 61.

Casing 61 is equipped with inspection window 65 between filter 6 air outlet and filter screen 64, inspection window 65 can open, clears up the polyester chip of accumulation in the filter 6.

The filter screen 64 is a detachable filter screen.

The bottom of the wet silo 2 is provided with a rotary valve.

The utility model discloses a theory of operation:

the wet polyester chips are discharged from a wet stock bin 2 through a rotary valve and reach the upper surface of a screen plate in a crystallization bed 1, air sent out by a crystallization fan 3 is heated by a heater 4 and then reaches the bottom of the crystallization bed 1, the polyester chips stacked on the screen plate are blown up through meshes on the screen plate to be in a boiling state for crystallization, then most of the air with flow carries a small amount of polyester chips to enter a cyclone separator 5 for polyester chip separation, a small amount of polyester chips which are not completely separated are continuously blown into a filter 6 along with the air, a filter screen 64 of the filter 6 completely separates the polyester chips, the air without the polyester chips enters the crystallization fan 3 and circulates through the crystallization fan 3.
