Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a drying device for 1,4-cyclohexanediol. Background Art

[0002] 1,4-cyclohexanediol is an organic compound. As an important intermediate in the synthesis of a large number of fine chemical products, it is widely needed in the production process. However, when processing 1,4-cyclohexanediol, it is usually necessary to dry it. This step is mainly to remove moisture from cyclohexanediol, which can ensure the purity and stability of the product, thereby meeting the subsequent reaction or application requirements.

[0003] However, in the use of the existing 1,4-cyclohexanediol drying device, the total amount of 1,4-cyclohexanediol to be dried is large, resulting in deep accumulation, which affects the drying effect, reduces the drying efficiency, and requires a long drying time. In addition, when the existing 1,4-cyclohexanediol is stored, it contains a certain amount of moisture, which will cause agglomeration. The agglomerated 1,4-cyclohexanediol is not easy to be completely dried.

[0004] Therefore, in view of the fact that the above-mentioned 1,4-cyclohexanediol drying device cannot handle a large amount of 1,4-cyclohexanediol, resulting in low drying efficiency, a 1,4-cyclohexanediol drying device can be designed. Through a rotating adjustable structure combined with a vibration module, the drying efficiency is improved while the material accumulation problem in the feed bin is solved. Utility Model Content

[0005] In order to overcome the problem that the 1,4-cyclohexanediol drying device cannot handle a large amount of 1,4-cyclohexanediol, resulting in low drying efficiency.

[0006] The technical solution of the utility model is: a drying device for 1,4-cyclohexanediol, comprising a tripod, a base plate, a drying cylinder, a feeding assembly, a stirring structure, a vibration module, and a discharge pipe; the tripod is fixed to the lower end of the base plate, the drying cylinder is installed on the upper end of the base plate, the discharge pipe is installed on the outer wall of the drying cylinder, the feeding assembly is installed on the upper end of the drying cylinder, a distributed and staggered stirring structure is installed in the drying cylinder, and a vibration module with an external power supply is installed on the upper end of the discharge pipe.

[0007] Preferably, the feed assembly ensures that the material can enter the drying cylinder evenly and continuously to avoid blockage or uneven flow.

[0028] See also Figure 6In this embodiment, the drying cylinder 3 includes an observation window 301 and a ring light 302; the observation window 301 is installed on the outer wall of the drying cylinder 3, and the ring light 302 is installed on the outer wall of the drying cylinder 3 and located at the upper end of the observation window 301.

The model of the vibrator 601 can be ZK-0.1T, with a power of 15W, and vibration is achieved through an external power supply. The vibration bin 602 is a U-shaped structure and a steel plate is installed on the upper end. When the vibration module 6 is working, the powder gathered at the outlet of the discharge pipe 7 can be removed in time through the vibration output unit to avoid blockage.

[0029] When working, firstly, the 1,4-cyclohexanediol powder is piled in the feed bin 402, and the rotating motor 501 at the upper end of the drying cylinder 3 is started, which drives the rotating shaft 502 to rotate, so that the rotating shaft 502 drives the feed disk 401 to rotate, and the arc groove 404 on the feed disk 401 rotates synchronously and constantly overlaps with the bottom of the feed bin 402. When they overlap, the 1,4-cyclohexanediol powder in the feed bin 402 will fall into the drying cylinder 3 through the arc groove 404 for drying. This design can cooperate with the continuous rotation of the feed disk 401 to achieve the purpose of uniform and uniform feeding, thereby improving its drying efficiency;

[0030] At the same time, the rotating shaft 502 also drives the stirring rod 504 to rotate to stir the 1,4-cyclohexanediol powder. During the rotation of the stirring rod 504, it will continuously intersect with the material-beating rod 505 to break up some agglomerated 1,4-cyclohexanediol, further improving its drying efficiency.

[0031] In addition, through the vibration module 6 of the external power supply, the 1,4-cyclohexanediol accumulated at the outlet of the discharge pipe 7 can be cleared in time to avoid blockage. The staff can observe the drying condition of 1,4-cyclohexanediol through the observation window 301 at any time, and the ring light 302 can be turned on at night to avoid the problem of poor observation effect due to insufficient light.

[0032] Through the above steps, the synergistic effect of the feed component 4 and the stirring structure 5 is utilized to achieve uniform falling and breaking of the material, which significantly improves the drying effect. The addition of the vibration module 6 effectively solves the problem of powder aggregation at the outlet of the discharge pipe 7 and avoids the occurrence of blockage. Compared with traditional drying equipment, this design avoids the accumulation of materials in the feed bin 402, ensures the smooth progress of the drying process, improves the overall drying efficiency, and solves the problem that the 1,4-cyclohexanediol drying device cannot handle a large amount of 1,4-cyclohexanediol, resulting in low drying efficiency.
