As shown in fig. 1 and fig. 3, the color masterbatch dryer includes a housing 1, a stirring shaft 2, a spiral stirring paddle 3 and a guide plate 4; a feed inlet 5 and a discharge outlet 6 are arranged on the shell 1; the feed inlet 5 is arranged at the top of the shell 1, and the discharge outlet 6 is arranged at the edge of the bottom surface of the shell 1; the stirring shaft 2 is vertically arranged in the shell 1, and one end of the stirring shaft 2 penetrates through the bottom of the shell 1 and is connected with the driving motor 7; the spiral stirring paddle 3 is arranged on the stirring shaft 2; the spiral stirring paddle 3 is used for stirring the color master batches by rotating with the stirring shaft 2 after the stirring shaft 2 is driven; the guide plate 4 inclines relative to the bottom surface of the shell 1, the guide plate 4 is connected with the shell 1 along the circumferential direction, an accommodating space is formed between the guide plate 4 and the bottom surface of the shell 1, as shown in fig. 2, a through hole 41 is formed in the guide plate 4, the stirring shaft 2 penetrates through the through hole 41, and a gap is formed between the guide plate 4 and the spiral stirring paddle 3; the guide plate 4 is used for guiding the color master batches falling from the upper part, so that the color master batches move to the discharge hole 6 along the guide plate 4 to be discharged. An air inlet 8 and an air outlet 9 are arranged on the side wall of the shell 1, and the air outlet 9 is positioned above the air inlet 8; the highest end of the guide plate 4 is lower than the air inlet 8.

As shown in fig. 2 and 3, the side wall of the housing 1 is provided with a plurality of limiting holes 12, and the limiting holes 12 are provided with internal threads; the guide plate 4 is provided with a plurality of positioning holes 43 corresponding to the limiting holes 12 one by one along the circumferential direction, threads are arranged in the positioning holes 43, the limiting holes 12 are connected with the positioning holes 43 through screws, sealing strips are arranged on the guide plate 4 along the circumferential direction, and the sealing strips are provided with holes which are the same in number, size and one-to-one correspondence with the positioning holes 43. The first surface of deflector 4 near casing 1 bottom surface is provided with the support pole, and casing 1's bottom surface is provided with the constant head tank, bracing piece 11 and constant head tank joint. The first surface is provided with a groove, and one end of the support rod 11, which is far away from the bottom surface of the shell 1, is clamped with the groove. A sealing ring is arranged between the stirring shaft 2 and the through hole 41. As shown in fig. 1, a fan 10 is disposed on the bottom surface of the housing 1, and the fan 10 is used for blowing air to the guide plate 4; the guide plate 4 is provided with a plurality of vent holes 42, the number of the vent holes 42 is multiple, and the diameter of the vent holes 42 is smaller than the size of the color master batch, so that the color master batch is left on a second surface, opposite to the first surface, of the guide plate 4.

the implementation principle of the embodiment is as follows: the spiral stirring paddle 3 rotates along with the stirring shaft 2 after the stirring shaft 2 is driven, the color master batches are scattered at all positions of the bottom under the stirring of the spiral stirring paddle 3 after entering from the feeding hole 5, and high-temperature gas enters from the air inlet 8 and then dries the color master batches, and then the high-temperature gas is discharged from the air outlet 9. The masterbatch is discharged from discharge gate 6 after drying, but because some masterbatch can fall and be kept away from discharge gate 6 department, so this some masterbatch can't be discharged. And deflector 4 slope sets up in casing 1, and all is connected with casing 1 bottom all around, so the masterbatch scatters on deflector 4 under the stirring of spiral stirring rake 3, because the lowest setting of deflector 4 is in discharge gate 6 department, so the masterbatch can move to discharge gate 6 direction along deflector 4 under the effect of gravity and stirring. The guide plate 4 is disposed below the screw paddle 3, and guides the color mother particles without interfering with the stirring by the screw paddle 3.

In addition, 4 highest ends of deflector set up the downside at air intake 8, and the speed is great, energy loss is few when high-temperature gas gets into from air intake 8, easily blows the masterbatch that drops on deflector 4, can prevent the masterbatch adhesion on deflector 4, has accelerated the speed that the masterbatch removed to discharge gate 6 along deflector 4 moreover to a certain extent. The guide plate 4 is detachably connected with the shell 1 through screws, so that the guide plate 4 can be replaced by taking down the screws when the guide plate needs to be replaced, and the replacement is more convenient. Besides, the sealing strip can seal the guide plate 4, so that the color master batches are prevented from falling into the accommodating space formed between the guide plate 4 and the bottom surface of the shell 1 from a gap between the guide plate 4 and the sealing strip.

When installation deflector 4, earlier bracing piece 11 and recess joint, locating hole 43 is more easily alignd with spacing hole 12, and the screw can be easier when being connected deflector 4 and casing 1. And the supporting rod 11 can be replaced under the condition that the guide plate 4 is not replaced when being damaged, and the replacement is more convenient. In addition, the sealing ring can prevent the color master batch from entering the accommodating space between the guide plate 4 and the bottom of the shell layer, and the sealing ring reduces the direct friction between the stirring shaft 2 and the guide plate 4.

Because the guide plate 4 is close to the air inlet 8 and the temperature of the high-temperature gas is high, the local temperature of the guide plate 4 close to the air inlet 8 is extremely easy to be too high, but when the temperature of the color master batch is too high, the quality of the color master batch can be changed. The fan 10 can blow air from the accommodating space through the hole to the upper side of the guide plate 4 to dissipate locally excessive heat of the guide plate 4 into the space above the guide plate 4. In addition, the diameter of the hole is smaller than the width of the narrowest part of the color master batch, so the color master batch cannot penetrate through the hole and leak into the accommodating space between the guide plate 4 and the bottom of the shell layer.

the embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
