Description
Technical field
The invention belongs to the fluidized bed type pre-crystallizer apparatus technical field of polyester slice, particularly relate to a kind of full fluidisation equal time conveying pre-crystallizer.
Background technology
In the dry run of polyester slice, need first wet section to be carried out pre-crystallized, object prevents section from dry run, producing adhesion caking.Therefore must destroy the adhesion of section with air-flow boiling in pre-crystallizer, in prior art by the hot-air after heating from continuous pulsation formula blowing under pre-crystallizer fluid bed web plate, making section on web plate produce boiling and stoping section at high temperature to produce adhesion.Under web plate, air intake passage adopts and progressively reduces formula passage, makes section produce violent boiling at web plate middle front part, in after inner generating layer move promotion, section Step crystallization.But adopt this technical scheme to have 2 deficiencies, first, web plate middle front part concentrates on this region because of intake 70%, makes section produce violent boiling, partially sliced also fully not pre-crystallized, just by wind to feed opening, cause section tentatively pre-crystallized.The second, because section during boiling is inconsistent by the height of dishing out, cause seldom partially sliced being inhaled in exhausting air channel, discharge together with dust from cyclone separator, cause section again to clean reuse, produce waste.
Summary of the invention
The object of the invention is to solve above-described technical problem, one is provided to avoid section, when pre-crystallized, the inconsistent phenomenon of crystallization time occurs, improve the uniformity of the pre-crystallized degree of section, avoid the pre-crystallizer carried when the full fluidisation of the generation of dust material is equal in boiling process of cutting into slices, its technical scheme is as follows simultaneously:
A pre-crystallizer for conveying when full fluidisation is equal, comprise casing, it is characterized in that, the bottom of described casing is provided with web plate, is provided with blanking port between one end of web plate and bottom half; Be provided with the first division board, the second division board and the 3rd division board in described casing, the first division board offer the first discharging opening, between the second division board and web plate, be provided with the second discharging opening, the 3rd division board offers the 3rd discharging opening; The top of described casing is provided with return air pump orifice; The sidewall of described casing is provided with wet section tremie pipe, and described wet section tremie pipe communicates with the space that the first division board and casing are formed; Described blanking port is positioned at the space that the 3rd division board and casing are formed.
Preferred embodiment is, the bottom of the first described division board and the 3rd division board is provided with manual blowing plate, and manual blowing plate can make the first division board, the 3rd division board respectively and form breach can close this breach between web plate.
Preferred embodiment is, the height of the first described discharging opening in casing is higher than the second discharging opening, and the A/F of the first discharging opening is greater than the second discharging opening.
The pre-crystallizer of conveying when full fluidisation provided by the invention is equal, by the first division board, the second division board and the 3rd division board, is separated into 4 independently pre-crystallized boiling spaces whole casing, avoids the generation of section dust material in boiling process.First division board, the second division board and the 3rd division board and the first discharging opening, the second discharging opening, arranging of the 3rd discharging opening can make section in three independently pre-crystallized space, after making section mix boiling by hot-air by the blowout of bottom web plate, enter successively in each space until in drying tower, avoid section, when pre-crystallized, the inconsistent phenomenon of crystallization time occurs, improve the uniformity of the pre-crystallized degree of section.
The present invention is further provided with manual blowing plate, the first division board and web plate is controlled with the manual blowing plate of manual adjustments, the unlatching of the narrow slit between the second division board and web plate and closing, during for stopping production falls the section complete liquidation in three independently pre-crystallized boiling space.
The invention has the beneficial effects as follows: avoid section, when pre-crystallized, the inconsistent phenomenon of crystallization time occurs, improve the uniformity of the pre-crystallized degree of section, avoid the generation of section dust material in boiling process simultaneously.

Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
Embodiment is illustrated below in conjunction with Fig. 1:
As shown in Figure 1, the pre-crystallizer of conveying when a kind of full fluidisation is equal, comprise casing 1, the bottom of described casing 1 is provided with web plate 2, is provided with blanking port 3 between bottom one end of web plate 2 and casing 1; Be provided with in described casing 1 first division board 4, second division board 5 and the 3rd division board 6, first division board 4 to offer to be provided with on the second discharging opening the 8, three division board 6 between the first discharging opening 7, second division board 5 and web plate 2 and offer the 3rd discharging opening 9; The top of described casing 1 is provided with return air pump orifice 10; The sidewall of described casing 1 is provided with wet section tremie pipe 11, and the space that described wet section tremie pipe 11 and the first division board 4 and casing 1 are formed communicates.The first described division board 4 and the bottom of the 3rd division board 6 are provided with manual blowing plate 12, and manual blowing plate 12 can make the first division board 4, the 3rd division board 6 respectively and form breach can close this breach between web plate 2.The height of the first described discharging opening in casing is higher than the second discharging opening, and the A/F of the first discharging opening is greater than the second discharging opening; Described blanking port is positioned at the space that the 3rd division board and casing are formed.
First division board of the present invention, the second division board and the 3rd division board adopt corrosion resistant plate, and casing is separated into 4 independently boiling spaces, and the total height of the first division board is 2m, and in the plate, 70cm place opens the first wide discharging opening of a 10cm; The total height of the second division board is 1.7m, bottom the second division board, open the second wide discharging opening of a 2.5cm with web plate junction, and highly for 50cm place opens the 3rd wide discharging opening of one article of 5cm on the 3rd division board, return air pump orifice moves to above blanking channel.
Manual blowing plate and the first division board and web plate, narrow slit between second division board and web plate is the height narrow slit of a 6cm, the first division board and web plate is controlled with the manual blowing plate of manual adjustments, the unlatching of the narrow slit between the second division board and web plate and closing, during for stopping production falls the section complete liquidation in three independently pre-crystallized boiling space.
Wet section of the present invention enters in the space that the first division board and casing formed through wet section tremie pipe, carry out full fluid boiling pre-crystallized, then the space of the first division board and the formation of the second division board is entered into by the first discharging opening, by full fluid boiling, section enters the space that the second division board and the 3rd division board formed from the second discharging opening again, again to be entered by the 3rd discharging opening after boiling in the space that the 3rd division board and casing formed, enter drying tower finally by blanking port.Such section is in first three independently pre-crystallized space, and hot-air makes section mix boiling by the web plate blowout of bottom.
