[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.
[0020] Example
[0021] like Figure 1 , Figure 2 As shown, Figure 1 The figure shows the overall plan view of the drying device in the embodiment. Figure 2 It shows Figure 1 A partial cross-sectional diagram of the .
[0022] The device includes:
[0023] A drying box 10, wherein the top and bottom of the drying box 10 are respectively provided with a feed inlet 11 and a discharge outlet 12 which are connected to the interior of the box;
[0024] The dispersion component includes a shunt pipe 21 and a guide plate 24. The shunt pipe 21 includes a plurality of pipes that are interconnected. The feed ends of the plurality of pipes are all connected to the feed port 11. The discharge ends of the plurality of pipes are connected to different positions on the top of the drying box 10. The plurality of guide plates 24 are obliquely arranged on opposite side walls inside the drying box 10, and the uppermost guide plate 24 is arranged at a position corresponding to the bottom of the discharge end of the shunt pipe 21.
[0025] The drying component is arranged on the drying box 10 , and the drying component introduces hot air into the drying box 10 to dry the masterbatch.
[0026] By setting a dispersion component, the masterbatch added in the feed port 11 is dispersed into the drying box 10 through the shunt pipe 21, and combined with a plurality of guide plates 24 arranged below the discharge end of the shunt pipe 21, the dispersion degree and flow path of the masterbatch are improved, and the drying time and drying effect of the masterbatch are effectively improved. The drying component introduces hot air into the drying box 10 to dry the masterbatch.
[0027] like Figure 1 , Figure 2 As shown, Figure 1 The figure shows the overall plan view of the drying device in the embodiment. Figure 2 It is shown that Figure 1 A partial cross-sectional diagram of the .
[0028] The guide plates 24 are symmetrically arranged on opposite inner walls of the drying box 10, and a group of guide plates 24 located on the same straight line are arranged in a V-shape and an inverted V-shape with an opening from the top to the bottom.
[0029] The symmetrically arranged guide plates 24 allow the master batches entering the drying box 10 at the same time and in the same batch to be dried more evenly. The inclined V-shaped and inverted V-shaped guide plates 24 gradually guide the master batches to the discharge port 12 for discharge and collection.
[0030] The drying assembly includes a hot air blower 22 and an air supply pipe 23. The air supply pipe 23 is vertically arranged at the position of the symmetric axis between the symmetrical guide plates 24. A plurality of air supply ports 231 are arranged through the side wall of the air supply pipe 23. The hot air blower 22 is arranged on the outer top wall of the drying box 10. The output end pipe of the hot air blower 22 is connected to the top of the air supply pipe 23.
[0031] The output end of the hot air blower 22 outputs hot air, and enters the drying box 10 through the air supply pipe 23 to dry the masterbatch. The air supply ports 231 are evenly arranged on the side walls of the air supply pipe 23 to try to make the masterbatch dry fully and evenly.

[0035] Working principle: When using this device to dry plastic masterbatch, the masterbatch is added from the feed port 11, and the masterbatch is dispersed into the drying box 10 through the diverter pipe 21, and passes through the multiple groups of guide plates 24 below the discharge end of the diverter pipe 21 in sequence. At the same time, the hot air blower 22 is turned on, and the output end of the hot air blower 22 outputs hot air. The hot air enters the drying box 10 through the air supply pipe 23 to dry the masterbatch rolling on the guide plate 24. Finally, the masterbatch is gradually guided to the discharge port 12 and discharged and collected.
