Description

Technical Field

[0001] The utility model relates to the technical field of pill drying, in particular to a spiral falling pill drying device. Background Art

[0002] Spiral falling pill drying technology is an innovative drying process that optimizes the drying process of pills to ensure drying efficiency and uniformity of pills in batch production. Compared with common pill drying methods such as static drying or simple tumbling drying, spiral falling drying technology provides more efficient and consistent drying effects.

[0003] In the common spiral drop drying device, the pills move downward along a spiral channel. This design allows the pills to slowly fall under the action of gravity while fully contacting the drying medium, thereby accelerating the evaporation of water. However, this design has a disadvantage. When the pills reach the bottom of the drying cylinder, they tend to pile up together, which reduces the gaps between the pills and reduces the heat transfer efficiency. This in turn causes uneven heating of the pill surface, and some areas may be over-dried while other areas may not be fully dried.

[0004] Therefore, it is necessary to design a spiral falling pill drying device that can prevent pills from piling up to solve the above problems. Utility Model Content

[0005] In order to overcome the disadvantage that in the common spiral falling drying device, the pills fall unidirectionally along the spiral path, but when the pills fall on the bottom of the drying cylinder, they are easily accumulated at the bottom of the drying cylinder, resulting in uneven heating on the surface of the pills and failure to obtain sufficient drying, this utility model provides a spiral falling pill drying device that can prevent pill accumulation.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides the following technical solutions: a spiral falling pill drying device, comprising a bracket, a conical drying furnace, an interlayer, a mounting frame, a motor, a rotating rod, a spiral belt, a drying machine, an air guide pipe, a first valve, a feed port and an electromagnetic valve, a conical drying furnace is installed on the bracket, an interlayer is provided inside the conical drying furnace, a mounting frame is provided on the conical drying furnace, a motor is installed on the mounting frame, the lower end of the output shaft of the motor is connected to the rotating rod through a coupling, and the rotating rod passes through the top of the conical drying furnace, One end of the rotating rod located inside the conical drying furnace is connected to a spiral belt, a dryer is installed on the upper part of the mounting frame, an air duct is connected to the dryer, the end of the air duct is connected to the conical drying furnace, a first valve is arranged on the air duct, a feed port is arranged on the front side of the top of the conical drying furnace, an electromagnetic valve is installed at the bottom of the conical drying furnace, and it also includes a reciprocating screw rod, a push plate and a limit rod. A reciprocating screw rod is arranged on the rotating rod, and a push plate is threadedly arranged on the reciprocating screw rod. Two limit rods are fixedly connected to the inside of the conical drying furnace, and the push plate slides up and down along the limit rods.

[0007] Preferably, a screen and a shift rack are also included. The shift rack is installed at one end of the rotating rod close to the motor. The rotating rod passes through the screen. The screen is arranged at the upper part of the conical drying furnace, and the shift rack rotates in the screen.

[0008] Preferably, it also includes a Y-shaped connecting pipe and a second valve. The air outlet of the dryer is connected and communicated with the Y-shaped connecting pipe. The second valve is arranged on the Y-shaped connecting pipe. The other two branches of the Y-shaped connecting pipe are respectively connected and communicated with the left and right sides of the conical drying furnace.

[0009] Preferably, a heat-conducting copper sheet is also included, and the heat-conducting copper sheet is arranged in the interlayer of the conical drying furnace.

[0010] Preferably, a fixing block is further included, the fixing block is fixedly connected to the bracket on one side close to the dryer, and the Y-shaped connecting pipe passes through the fixing block.

[0011] Preferably, an observation plate is also included, and the conical drying furnace and the heat-conducting copper sheet are penetrated by the observation plate.

[0012] The beneficial effects of the utility model are as follows: 1. When the motor drives the spiral belt to rotate through the rotating rod, the spiral belt raises the pills along the wall of the conical drying furnace. When the pills reach the top of the spiral belt, they fall naturally and fall back into the bottom of the conical drying furnace. At the same time, the rotation of the rotating rod drives the reciprocating screw to rotate, so that the push plate moves up and down to lift the pills, ensuring that the pills are evenly distributed in the conical drying furnace and avoiding the accumulation of pills at the bottom of the conical drying furnace.

[0013] 2. When adding pills, the pills fall on the screen. The rack rotates to stir the pills that fall on the screen, so that the pills fall into the gaps of the screen and enter the bottom of the conical drying furnace for stirring, preventing too many pills from being added at one time, which will cause the drying effect of the conical drying furnace to decrease.

[0014] 3. By opening the second valve, hot air flows from the Y-shaped connecting pipe into the bottom of the conical drying furnace, and then rises from the bottom of the conical drying furnace. When the hot air rises, it will be evenly distributed in the entire space, thereby improving the drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The motor 4 for driving the rotating rod 5 is installed on the mounting frame 3. The lower end of the output shaft of the motor 4 is connected to the rotating rod 5 through a coupling. The rotating rod 5 passes through the top of the conical drying furnace 2. The end of the rotating rod 5 located inside the conical drying furnace 2 is connected to a spiral belt 6 for transporting materials. The upper rear of the mounting frame 3 A dryer 7 is installed, and an air guide pipe 8 for guiding air is connected to the dryer 7. The end of the air guide pipe 8 is connected to the conical drying furnace 2. A first valve 9 for controlling hot air is arranged on the air guide pipe 8. A feeding port 10 for feeding is arranged on the front side of the top of the conical drying furnace 2. An electromagnetic valve 11 for shielding pills is installed at the bottom of the conical drying furnace 2. It also includes a reciprocating screw rod 12, a push plate 13 and a limit rod 14. A reciprocating screw rod 12 is arranged on the rotating rod 5, and a push plate 13 is threadedly arranged on the reciprocating screw rod 12. Two limit rods 14 are arranged inside the conical drying furnace 2 by welding, and the push plate 13 slides up and down along the limit rod 14.

[0025] When it is needed, the pills are first poured in from the feed port 10, and then the motor 4 is started. The motor 4 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the spiral belt 6 to rotate. The spiral belt 6 spirally raises the pills along the wall of the conical drying furnace 2. When it reaches the top of the spiral belt 6, the pills fall naturally and fall into the bottom of the conical drying furnace 2 again. At the same time, the dryer 7 is started, and the first valve 9 is opened, and the hot air generated by the dryer 7 is introduced into the conical drying furnace 2 through the air guide pipe 8, so that the inside of the conical drying furnace 2 is heated to achieve the effect of drying the pills. At the same time, the rotating rod 5 rotates to drive the reciprocating screw rod 12 to rotate, and the reciprocating screw rod 12 drives the push plate 13 to move up and down along the limit rod 14 to lift the pills to prevent the pills from accumulating at the bottom, ensure that the pills are evenly distributed in the conical drying furnace 2, and avoid the pills from accumulating at the bottom of the conical drying furnace 2. When the pills are completely dried, the motor 4 is turned off, and the electromagnetic valve 11 is opened, the pills fall out through the electromagnetic valve 11, and then the pills are collected.

The screen 15 for quantitative feeding is provided at the upper part of the conical drying furnace 2, and the shifting rack 16 rotates in the screen 15.

[0027] When adding pills, the pills enter the interior through the feed port 10 and fall on the screen 15. After the pills are poured in, the motor 4 is started, and the motor 4 drives the rotating rod 5 to rotate. The rotating rod 5 drives the shifting rack 16 to rotate, and the shifting rack 16 rotates to stir the pills that fall on the screen 15, so that the pills fall into the gap of the screen 15 through stirring and enter the bottom of the conical drying furnace 2 for stirring, so as to prevent too many pills from being added at one time, which will cause the drying effect of the conical drying furnace 2 to decrease.

[0028] See also Figure 6 and Figure 7 As shown, it also includes a Y-shaped connecting pipe 17 and a second valve 18.

[0029] After the pills are poured into the conical drying furnace 2, the second valve 18 is opened, and the hot air flows into the bottom of the conical drying furnace 2 from the Y-shaped connecting pipe 17, and then rises from the bottom of the conical drying furnace 2. When the hot air rises, it will be evenly distributed in the entire space, thereby improving the drying efficiency. At the same time, a heat-conducting copper sheet 19 can be set in the interlayer 201 of the conical drying furnace 2 to accelerate the transfer of hot air inside the conical drying furnace 2 and ensure that the pills are dried evenly.
