Abstract

The present invention relates to an apparatus for collecting pellets. According to the present invention, even if a coolant passes through a dehydrator (30) to be dehydrated together with a cut pellet (P) from an extruder (B), moisture is still contained therein. Therefore, dry wind of a main blower (54a) is blown into a lower tunnel (52b) by passing through a wind inlet (50f) in a state of inputting the pallet (P) dehydrated in the dehydrator (30) into an upper tunnel (52a) of a collection box (52) through an upper inlet (50a), and is discharged to a wind outlet (50g) after passing through air holes (53a) and the upper tunnel (52a) as well as the lower tunnel (52b) so as to dry moisture contained in the pellet (P) and to three-dimensionally dry even water drops falling from the pellet (P) through the dry wind passing through the lower tunnel (52b). In addition, the coolant is directly dropped to a base water tank (31) through a lower net (33a) and a lower hole (32a) to improve dehydration efficiency, and at the same time, the pellet (P) is raised through an impeller (36) to dehydrate even the coolant by centrifugal force such that the coolant is inputted to an upper inlet (50a) of a collection box (52), thereby realizing rapid dehydration and rapid transfer of the pellet (P) to a collector (50).

The cooling water can be dropped directly into the base water tank 31 through the lower net 33a and the downhole 32a to increase the dewatering efficiency, and at the same time, while raising the pellet P through the impeller 36, the centrifugal force is increased. By dehydration to the cooling water to be introduced into the upper inlet (50a) of the collection box 52 to realize the rapid dehydration and the rapid transfer of the pellet (P) to the collector 50.

Impeller 36 is a rotary body 36a that is rotated by the rotational force of the dehydration motor 34, and spirally protrudes along the outer periphery of the rotating body 36a attracts the pellets (P) guided to the lower net (33a) Pellets (P) guided to the lower net (33a) of the inner cylindrical net (33) via the outer cylinder (32), including a spiral blade (36b) to be raised and dropped to the upper inlet (50a) of the collection box (52) ) As a spiral blade (36b) to enable dehydration while being able to quickly transfer to the upper inlet (50a) of the collection box 52 to realize a more efficient collection of pellets (P).

At this time, the spiral blade 36b is provided with dehydration holes 36c to allow the cooling water to escape through the dehydration holes 36c in the process of raising the pellet P so as to maximize the dewatering efficiency, and furthermore, the spiral blade 36b. The blade 36b has transverse projection lines 36d so that the pellet P is applied to the transverse projection lines 36d when centrifugal force is applied by the spiral blade 36b which rotates together with the rotor 36a. As it rises across it, the transfer to the collection box 52 can be ensured more smoothly.

In addition, the inner cylindrical network 33 is provided with an inner door 33b to be opened and closed, and the outer cylindrical body 32 is provided with an outer door 32b to be opened and closed, and agglomerated in the dehydration process of the pellets P. When it appears, the outer door 32b and the inner door 33b are opened to allow for quick repair.

Then, the filtering net 37 is interposed between the outer cylindrical body 32 and the base water tank 31 to filter the pellets (P) contained in the coolant falling through the lower net 33a and the downhole 32a. Including, when the pellet (P) falling through the lower net 33a during the dehydration in the dehydrator 30 to collect and recycle to the strainer 37 to contribute to recycling and at the same time to recycle the cooling water pellet ( Block the blockage caused by P).

On the other hand, the induction furnace 35 guides the pellets P cut by the extruder B to the lower net 33a of the inner cylindrical net 33 together with the cooling water through the outer cylindrical body 32. ) And filter rods 35b erected in the middle of the guide plate 35a.

The dehydrator 30 and the collector (3) can be preliminarily filtered out of the pellet P cut too large from the extruder B by the filter rods 35b erected in the middle of the guide plate 35a of the induction furnace 35. 50) It is possible to prevent the phenomenon which causes the collection failure in the inside in advance.

Furthermore, the dehydrator 30 applied to the pellet collecting device according to the present invention further includes a perforation hole 35c provided in the lower portion of the guide plate 35a to drop the coolant into the base water tank 31 in advance. To achieve dehydration.

Preferably, the dehydrator 30 is the upper inlet 50a of the collection box 52 via the inner cylindrical network 33 and the outer cylindrical body 32 to the pellet (P) raised while being dewatered through the impeller 36 It is provided with a guide barrel 38 to guide, so that the entire amount of the pellet (P) can be collected without loss.

Specifically, the induction cylinder 38 is in communication with the inner cylindrical network 33 and the outer cylindrical body 32 is in communication with the lower inclined guide passage 38a for inducing the pellet (P) downward, and the lower inclined guide passage 38a. Including a vertical guide passage 38b for guiding the pellets P to the upper inlet 50a, while ensuring a smooth transfer of the pellets P through the lower slope guide passage 38a, the vertical guide passage 38b It is possible to ensure a rapid drop to the upper inlet (50a) of the collection box 52 through.

At this time, the vertical induction through 38b is further provided with an upper vent 38c, so that the dry air of the main blower 54a passes through the inlet 50f, through the lower channel 52b, the air holes 53a, and the upper channel ( Partial exit to the vertical guide passage 38b and the upper vent opening 38c via 52a) is realized until the initial drying of the pellets P.

The present invention can be used in the industrial field for producing pellets by cutting while simultaneously heating the synthetic resin composition.
