Technical Field
[0001] The utility model belongs to the technical field of drying equipment, in particular to drying equipment for acetyl tri-n-butyl ester. Background Art
[0002] Acetyl tri-n-butyl ester is a new type of non-toxic additive and plasticizer that can be used in plastic processing industries such as food packaging, medical devices, children's toys, and personal hygiene products. It has good compatibility with plastics such as PVC and vinyl chloride-vinyl acetate copolymer. The plastics plasticized with it have good low-temperature flexibility and are heat-stable, light-resistant, water-resistant, and cold-resistant during sealing.
[0003] Acetyl tri-n-butyl ester needs to be dried before use. Although some existing drying equipment can complete the drying process, the equipment needs to be frequently switched on and off to load and unload materials during the drying process, which greatly affects the drying efficiency. The air entering the drying equipment is not dried, so moisture in the air enters the drying equipment, affecting the drying effect. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0022] See also Figure 1-5 As shown, the utility model is a drying device for acetyl tri-n-butyl ester, comprising a drying cylinder 1, a feed port 101 extending through the top of the drying cylinder 1, and a pipe 2 fixedly connected to the interior of the drying cylinder 1, the pipe 2 being spirally arranged, a volatilization hole 201 extending through the wall of the pipe 2, and a plurality of groups of volatilization holes 201, and a discharge port 202 fixedly connected to one end of the pipe 2 near the bottom of the drying cylinder 1, the spirally arranged pipe 2 can extend the time for acetyl tri-n-butyl ester to pass through the pipe 2, thereby fully drying the acetyl tri-n-butyl ester, the volatilization hole 201 can promptly discharge the moisture volatilized by the acetyl tri-n-butyl ester during the drying process, and prevent the moisture from staying inside the pipe 2 and affecting subsequent drying, and the discharge port 202 can promptly discharge the acetyl tri-n-butyl ester from the drying cylinder 1 after the drying is completed, and avoid switching the equipment back and forth and affecting the drying efficiency;
[0023] The feed box 3 is arranged above the feed port 101, and the interior of the feed box 3 is connected to the interior of the drying cylinder 1. A feed plate 301 is fixedly connected to the top of the feed box 3, and a guide plate 302 is fixedly connected to the interior of the feed box 3. The guide plates 302 are cross-arranged in three groups, and the guide plates 302 are arranged at an angle. The cross-arranged guide plates 302 can slow down the speed at which tri-n-butyl acetyl enters the pipeline 2, so that tri-n-butyl acetyl enters the pipeline 2 slowly and evenly, thereby preventing the tri-n-butyl acetyl from falling too quickly and causing insufficient drying.
[0024] The drying mechanism includes a drying box 4, an electric heating wire 401, a fixed plate 1 402, a fan 403 and a drying net 404. The bottom end of the drying cylinder 1 is fixedly connected to the drying box 4, the top of the drying box 4 is fixedly connected to the electric heating wire 401, the inner wall of the drying box 4 is fixedly connected to the fixed plate 1 402, the top of the fixed plate 1 402 is fixedly connected to the fan 403, the bottom end of the drying box 4 is fixedly connected to the drying net 404, the inner wall of the exhaust hole 5 is fixedly connected to the fixed plate 2 501, and one side of the fixed plate 2 501 is fixedly connected to the exhaust The air fan 502 and the drying net 404 can absorb moisture in the air to prevent humid air from entering the drying cylinder 1 and affecting the drying effect. The fan 403 heats the dry air through the heating wire 401 and then sends it into the drying cylinder 1, so that the pipe 2 is evenly heated, thereby evenly drying the acetyl tri-n-butyl ester inside the pipe 2. The exhaust fan 502 set at the top of the drying cylinder 1 can quickly discharge the water vapor volatilized during the drying process into the drying cylinder 1 through the exhaust hole 5, so as to prevent the water vapor from staying inside the drying cylinder 1 and affecting subsequent drying.
[0025] Working principle: Before loading, turn on the heating wire 401 and the fan 403. The fan 403 heats the air dried by the drying net 404 through the heating wire 401 and then sends it into the drying cylinder 1, thereby preheating the pipe 2 inside the drying cylinder 1. After the pipe 2 is preheated, acetyl tri-n-butyl ester is introduced into the feed box 3 through the feed plate 301. The cross-arranged guide plates 302 inside the feed box 3 can slow down the speed of acetyl tri-n-butyl ester entering the pipe 2, so that acetyl tri-n-butyl ester slowly and evenly enters the pipe 2 through the feed port 101. The spirally arranged pipe 2 prolongs the time for acetyl tri-n-butyl ester to fall, thereby fully drying the acetyl tri-n-butyl ester. The moisture generated during the drying process is discharged from the pipe 2 through the volatilization hole 201, and then the exhaust fan 502 is turned on. The exhaust fan 502 can discharge the water vapor inside the drying cylinder 1 through the exhaust hole 5. After drying is completed, acetyl tri-n-butyl ester is discharged and collected through the discharge port 202.
