Description

Technical Field

[0001] The utility model relates to the technical field of feed additive production, and more specifically to a circulation guide mechanism of a drying device. Background Art

[0002] Feed additives refer to small or trace substances added during the production, processing and use of feed. The amount used in the feed is very small but the effect is significant. During the production process of feed additives, drying equipment is needed to dry them.

[0003] After searching, the utility model patent with announcement number CN220507571U discloses a feed additive drying device. By setting a driving mechanism, a rotating shaft, a breaking rod and a power unit, the driving mechanism can spread the additives added to the containing boxes while driving the multiple containing boxes to move horizontally back and forth. In the process of continuous reciprocating motion of the containing boxes, the power unit drives the breaking rods on the multiple rotating shafts to rotate, which can not only break up the adhering additives, but also flip the middle and bottom layers of the additives upwards, thereby improving the drying efficiency of the additives and making the additives heated evenly, thereby ensuring uniform drying of the additives.

[0004] However, the above patents still have the following shortcomings: the drying modules are located on both sides of the drying box, which will cause uneven heating of the feed additives in the box, affecting the quality of drying; and the ventilation module will discharge the gas containing heat, which is easy to cause energy waste. For this reason, we propose a circulation guide mechanism for the drying device. Utility Model Content

[0040] In this embodiment, it is ensured that the moisture-absorbing cloth 19 can completely filter and absorb the hot air passing through the inner cavity of the heating box 3, so as to absorb the water vapor in the hot air.

[0041] Working principle: when in use, first place the feed additive to be dried into the containing box 2, start the vacuum pump 4 to extract air from the inner cavity of the heating box 3, and at the same time, the inner cavity of the heating box 3 makes the suction hood 11 generate suction, and the suction force of the suction hood 11 is used to draw the gas in the drying box 1 from the suction hood 11, the suction pipe 10, and the exhaust pipe 9 into the heating box 3, and the electric heating tube 12 is used to heat the gas, and the heated gas enters the gas distribution ring 7 from the return air pipe 5 and the gas distribution pipe 6, and multiple nozzles 8 are used to blow the hot air in the gas distribution ring 7 onto the feed additive, thereby heating the feed additive, and the suction hood 11 continuously extracts air from the inner cavity of the drying box 1, so that the slightly cold gas in the drying box 1 re-enters the heating box 3 for repeated heating, and the moisture-absorbing cloth 19 in the heating box 3 adsorbs the water vapor in the hot air, and then the two servo motors 18 are started to drive the two winding drums 17 to rotate, so that the moisture-absorbing cloth 19 on one winding drum 17 is released, and the moisture-absorbing cloth 19 on the other winding drum 17 is collected. The reel 17 reels the moisture-absorbing cloth 19 and replaces the position of the moisture-absorbing cloth 19 for absorbing water vapor in the inner cavity of the heating box 3. Then, when the feed additives in the containing box 2 are dried, the switch valve 21 is opened, and the electric push rod 24 is started to drive the piston plate 25 to move upward. When the piston plate 25 moves upward, suction is generated at the bottom of the inner cavity of the air collecting box 22, thereby sucking the hot air in the drying box 1 into the inner cavity of the air collecting box 22. At this time, the inner cavity of the drying box 1 becomes a vacuum state. When all the hot air in the drying box 1 is sucked away, the switch valve 21 is closed to replace the dried feed additives in the containing box 2. Finally, when the containing box 2 is replaced with the feed additives to be dried, the vacuum pump 28 is started to draw the inner cavity of the drying box 1 into a vacuum state, the switch valve 21 is opened, and the electric push rod 24 is started to drive the piston plate 25 to move downward, so that the hot air in the air collecting box 22 moves back to the inner cavity of the drying box 1, so as to heat the servo additives in the drying box 1.

[0042] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto.
