Description

Technical Field

[0001] The utility model relates to the technical field of rotary flash evaporation dryers, and more particularly to an anti-clogging rotary flash evaporation dryer. Background Art

[0002] Spin flash dryers are primarily used to remove moisture from materials, achieving a specified dryness. In many industrial processes, such as those in the chemical, food, and pharmaceutical industries, excessive moisture content can impact product quality, stability, shelf life, and subsequent processing. For example, in the pharmaceutical industry, wet powders must be dried to an appropriate moisture content before subsequent steps like tableting and capsule filling. In food processing, raw materials like flour and starch are susceptible to mold and spoilage if their moisture content is too high. Spin flash dryers can extend their shelf life and facilitate storage and transportation.

[0003] When a common rotary flash dryer processes materials, it uses a rotary feeder to directly feed the materials into the rotary flash dryer for drying. When the materials are fed into the rotary flash dryer, there will be large particles of impurities and foreign matter in the materials, and for some materials with strong agglomeration, the materials will agglomerate. Large particles of impurities, foreign matter and agglomerated materials will greatly increase the possibility of agglomeration and blockage in the dryer. Utility Model Content

[0026] 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.

[0027] See also Figures 1 to 5 , In the utility model: an anti-clogging rotary flash dryer comprises a base 1, a body 2 is installed on the top of the base 1, a feeder 3 is installed on the left side of the base 1, the feed port of the feeder 3 is connected to the processing cylinder 4, and the left side of the processing cylinder 4 is connected to the feed pipe 5, the top of the processing cylinder 4 is fixedly connected to a motor 6, the output shaft of the motor 6 is fixedly connected to a rotating rod 7, the bottom end of the rotating rod 7 passes through and extends to the interior of the processing cylinder 4, two groups of stirring rods 8 arranged at equal distances are fixedly connected to the rotating rod 7, the bottom end of the rotating rod 7 is fixedly connected to a square rod 9, a sieve plate 10 is sleeved on the square rod 9 and is slidably connected thereto, the outer side of the sieve plate 10 contacts the inner wall of the processing cylinder 4, the bottom of the sieve plate 10 is fixedly connected to a rotating ring 11, the outer side of the rotating ring 11 is fixedly connected to two sliding rods 12, and the inner wall of the processing cylinder 4 is fixedly connected to two triangular blocks 13.

[0028] In the present invention, when in use, the material is first added into the processing cylinder 4 through the feed pipe 5, and then the user turns on the motor 6 to drive the rotating rod 7 to rotate. During the process, the rotating rod 7 will drive the stirring rod 8 to rotate to impact the material, thereby achieving the effect of breaking the agglomerated material. During the process, the sieve plate 10 will screen out large particles, impurities, foreign matter and agglomerated materials, and the loose material will pass through the sieve plate 10 and fall into the feeder 3. The feeder 3 can be turned on to feed the loose material into the main body 2, and then hot air is sent into the main body 2 to dry the material.

[0029] During the rotation process, the rotating rod 7 will drive the sieve plate 10 to rotate through the square rod 9. After the sieve plate 10 rotates, it will drive the sliding rod 12 to continuously slide over the triangular block 13 through the rotating ring 11. When the sliding rod 12 slides onto the triangular block 13, the sliding rod 12 will drive the rotating ring 11 to rise until the sliding rod 12 completely slides over the triangular block 13. At this time, the sieve plate 10 will fall. As the sliding rod 12 continues to slide over the triangular block 13, the sieve plate 10 will reciprocate up and down. The reciprocating motion of the sieve plate 10 will vibrate and roll the material, thereby effectively improving the screening and crushing effect of the material.

[0030] See also Figure 4 , wherein: the right side of the processing cylinder 4 is fixedly connected to the air inlet box 14, the top of the air inlet box 14 is installed with a fan 15, the air outlet end of the fan 15 is connected to the air inlet box 14, the left side of the air inlet box 14 is connected with a horizontal pipe 16, the rotating rod 7 is sleeved with an air ring 17 rotatably connected to it, the left end of the horizontal pipe 16 passes through the processing cylinder 4 and is connected to the air ring 17, the rotating rod 7 is arranged in the air, and the top of the rotating rod 7 is provided with an annular air inlet hole 18 connected to the air ring 17, the stirring rod 8 is hollow and connected to the rotating rod 7 through a conduit, and the stirring rod 8 is provided with evenly distributed air jets 19.

[0031] In the present invention, during the process of screening and crushing the material, the user turns on the fan 15 to send air into the air inlet box 14, and then the air enters the air ring 17 from the cross pipe 16. The air then enters the rotating rod 7 from the air inlet hole 18 and is ejected from the air jet 19 on the stirring rod 8. The air sprayed toward the material can effectively improve the effect of crushing the material, and the air can also have a certain effect of drying the material.

[0032] See also Figure 5 , wherein: the slide bar 12 is provided with a roller 20 rotatably connected thereto, and the outer side of the roller 20 is in contact with the triangular block 13.

[0033] In the present invention, the roller 20 sleeved on the slide bar 12 can effectively reduce the wear between the slide bar 12 and the triangular block 13, thereby improving the practicality of the device.

[0034] See also Figure 4 , wherein: a waste box 21 slidably connected to the front of the air inlet box 14 is inserted, and a filter plate 22 is embedded in the bottom of the waste box 21.

[0035] In the present invention, the waste box 21 and the filter plate 22 cooperate to filter the dust in the air, thereby preventing the dust from causing secondary pollution to the material, thereby improving the practicality of the device.

[0036] See also Figures 1 to 4, wherein: a circular ring 23 is sleeved on the top of the body 2 and fixedly connected to it, an annularly distributed heat-conducting rod 24 is inserted through the inner wall of the circular ring 23, one end of the heat-conducting rod 24 is inserted into the body 2, an air inlet 25 is opened on the top of the circular ring 23, and an insulation pipe 26 is connected to the bottom of the circular ring 23, and the bottom end of the insulation pipe 26 is connected to the air inlet end of the fan 15.

[0037] In the present invention, after the fan 15 is turned on, air will enter the ring 23 from the air inlet 25, and then the air will flow in the ring 23. The heat-conducting rod 24 will transfer the heat in the main body 2 to the air, thereby achieving the effect of heating the air in the ring 23. After the air is heated, it will enter the air inlet box 14 from the insulation pipe 26. The hot air will then pass through the rotating rod 7, the stirring rod 8, and the air jet 19 in sequence into the processing cylinder 4. The hot air can preheat the material and improve the efficiency of drying the material.

[0038] See also Figure 5 , wherein: a waste outlet 27 is opened on the left side of the processing cylinder 4, and a sealing block 28 is threadedly connected to the inner wall of the waste outlet 27.

[0039] In the present invention, the rotating sealing block 28 can remove large particles of impurities and foreign matter on the sieve plate 10 from the waste outlet 27, thereby achieving the waste discharge effect.
