Description

Technical Field

[0001] The utility model relates to the technical field of vacuum single cone drying machine stirring, and more specifically, to a vacuum single cone drying machine stirring mechanism. Background Art

[0002] Vacuum single cone dryer is a kind of machine that uses spiral belt to rotate and lift the material and simultaneously introduces heat transfer medium into the conical jacket and hollow spiral belt, so that the heated material is lifted from all sides and falls from the middle, quickly and continuously circulates and turns, and the water vapor is taken away in time by vacuuming the cylinder, so that the material can be dried and mixed in a short time.

[0003] The stirring mechanism is one of the important components inside the vacuum single cone dryer. It can evenly stir the materials inside the vacuum single cone dryer to achieve drying of the materials.

[0004] After searching, a Chinese patent with publication number CN213687629U discloses a single-cone vacuum dryer. The advantage of this structure is that the material entering the single-cone dryer body can be driven upward under the action of the spiral stirring blade, avoiding the accumulation of material at the bottom of the single-cone dryer body, increasing the gap between the materials, and improving the drying efficiency. Under the action of the scraper, it is helpful to scrape off the material adhering to the inner wall of the single-cone dryer body during drying, avoiding the accumulation of material on the inner wall of the single-cone dryer body, affecting the next use.

[0005] However, in actual use, although this structure can stir and scrape the material, since the material can generally only be stirred horizontally when the spiral stirring blade is used to stir the material, it is not convenient to stir it vertically, which will affect the efficiency of material stirring.

[0024] As attached Figure 1 , 2As shown in Figure 4, the stirring assembly includes two connecting rods 5 arranged on both sides of the rotating rod 2, a movable cylinder 6 is provided on one side of the two connecting rods 5, a fixed ring 7 is provided on the two connecting rods 5 and on one side of the movable cylinder 6, movable frames 8 are hingedly provided on both sides of the two movable cylinders 6, and a first stirring rod 9 is hingedly provided on one side of the two movable frames 8, a rotating ring 10 is sleeved on the two movable cylinders 6, fixed rods 11 are provided on both sides of the rotating ring 10, a movable cylinder 12 is provided on one side of the two fixed rods 11, and a second stirring rod 13 is provided on one side of the two movable cylinders 12. When the rotating rod 2 is running, the first stirring rod 9 and the second stirring rod 13 can be driven to extend to one side by the movable cylinder 6 and the movable cylinder 12, so that the positions of the first stirring rod 9 and the second stirring rod 13 can be changed, thereby increasing the range of material stirring.

[0025] As attached Figure 1 , 3 As shown, the support assembly includes a first support rod 14 arranged at the bottom of the inner cavity of the vacuum single-cone dryer housing, and second support rods 15 are arranged on both sides of the support rod. One end of the two second support rods 15 is connected to the inner wall of the vacuum single-cone dryer housing. A support groove is opened on the bottom surface of the rotating rod 2, and the top of the first support rod 14 is clamped with the support groove. The bottom of the rotating rod 2 is clamped with the first support rod 14, which can support the rotating rod 2 and improve the stability of the rotating rod 2.

[0026] As attached Figure 4 As shown, one end of the two connecting rods 5 passes through the surface of the movable cylinder 6 and extends to the inside of the movable cylinder 6. One end of the two connecting rods 5 is provided with a first spring 4. One end of the two first springs 4 is connected to the inner wall of the movable cylinder 6. Through the elasticity of the first spring 4, the movable cylinder 6 is driven to move along the connecting rod 5, the position of the first stirring rod 9 can be changed, and the first stirring rod 9 can be recovered to the initial position.

[0027] As attached Figure 4 As shown, one end of the two fixed rods 11 passes through the surface of the moving cylinder 12 and extends into the inside of the moving cylinder 12.

[0029] The working principle of the utility model is as follows: when in use, firstly, the motor 1 is started to drive the rotating rod 2 to rotate.

By changing the position of the first stirring rod 9, not only the inner wall of the vacuum single cone dryer housing can be scraped, but also the stirring range of the first stirring rod 9 can be increased. Then, the second spring 16 is stretched toward one end by the inertia generated by the movable cylinder 6 when rotating, so that the movable cylinder 12 slides along the surface of the fixed rod 11, and the movable cylinder 12 drives the second stirring rod 13 to move to one side, so that the stirring range of the second stirring rod 13 can be increased.

[0030] When the rotating rod 2 is placed inside the housing of the vacuum single-cone dryer, the support groove at the bottom of the rotating rod 2 is engaged with the first support rod 14. When the motor 1 drives the rotating rod 2 to run, the bottom of the rotating rod 2 is rotated along the first support rod 14, which can support the bottom of the rotating rod 2, improve the stability of the rotating rod 2, and avoid the deviation of the rotating rod 2. The utility model can drive the movable cylinder 6 and the movable cylinder 12 to move along the connecting rod 5 and the fixed rod 11 through the deformation ability of the first spring 4 and the second spring 16, and then change the positions of the first stirring rod 9 and the second stirring rod 13, so as to stir the materials inside the housing of the vacuum single-cone dryer horizontally and vertically at the same time, thereby improving the efficiency of stirring the materials.
