Description

Technical Field

[0001] The utility model relates to the technical field related to double-cone vacuum dryers, in particular to a double-cone vacuum dryer used for the production of pyridine blue color-developing materials. Background Art

[0002] The double cone dryer is a double cone rotating tank. When the tank is in a vacuum state, steam or hot water is introduced into the jacket for heating. The heat contacts the wet material through the inner wall of the tank. The water vapor evaporated by the wet material after absorbing heat is pumped away through the vacuum exhaust pipe by the vacuum pump. Since the tank is in a vacuum state and the rotation of the tank makes the material constantly turn up and down and inside and outside, the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.

[0003] The existing double-cone vacuum dryer does not perform drying treatment when loading, and the materials are easily accumulated at the loading place. The double-cone vacuum dryer needs to be turned over as a whole in time. It is difficult to perform drying treatment during the loading process. The double-cone vacuum dryer adopts a single loading port, resulting in a relatively low processing efficiency of the double-cone vacuum dryer. Utility Model Content

[0027] The double-cone vacuum drying barrel 2 is fixedly mounted on the inner side of the support frame 1, so that the servo motor 3 is movably mounted on the top of the double-cone vacuum drying barrel 2, and the servo motor 3 on the double-cone vacuum drying barrel 2 is used to drive the drying and stirring;

[0028] Among them, a pre-mixing chamber 6 is fixedly connected to the top of the double-cone vacuum drying barrel 2, and a material port 5 is opened around the top of the pre-mixing chamber 6.

A pre-mixing motor 9 is movably installed inside the drying mixing box 8.

[0029] In this embodiment, the pyridine blue color-developing material is added to the inside of the double-cone vacuum drying barrel 2 through the material port 5, so that the pyridine blue color-developing material passes through the pre-mixing chamber 6 and the double-cone vacuum drying barrel 2. In the barrel, steam or hot water is introduced into the jacket for heating. The heat contacts the wet material through the inner wall of the barrel. The water vapor evaporated after the wet material absorbs heat is pumped away through the vacuum exhaust pipe by the vacuum pump. At the same time, the pyridine blue color-developing material can also be put into the feeding port 7. Starting the pre-mixing motor 9 can dry the pyridine blue color-developing material in the feeding port 7 and the drying mixing box 8.

[0030] Preferably, the double-cone vacuum drying barrel 2 and the pre-mixing chamber 6 have the same vacuum drying function. The pre-mixing chamber 6 is fixedly connected to the top of the double-cone vacuum drying barrel 2, so that the servo motor 3 is movably installed inside the pre-mixing chamber 6 through the main shaft 4. Under the drive of the servo motor 3, the raw materials in the pre-mixing chamber 6 and the double-cone vacuum drying barrel 2 can be dried. The pre-mixing chamber 6 and the double-cone vacuum drying barrel 2 are in a vacuum state, and steam or hot water is introduced into the jacket for heating. The heat contacts the wet material through the inner wall of the barrel, and the wet material absorbs heat and evaporates water vapor.

The loading port 7 and the material port 5 are respectively fixedly installed on the double-cone vacuum drying barrel 2 and the pre-mixing chamber 6, and can be loaded at the same time, thereby improving the processing efficiency of the double-cone vacuum dryer.

[0034] Preferably, the built-in stirring blade 12 is driven by the pre-stirring motor 9 to perform spiral motion in the dry mixing box 8 .

[0035] The drying mixing box 8 adopts a drying method. By using the same vacuum state as the pre-mixing chamber 6 and the double-cone vacuum drying barrel 2, the pyridine blue color-developing material can be fed and dried. After the pyridine blue color-developing material is dried, it is dried again through the pre-mixing chamber 6 and the double-cone vacuum drying barrel 2. After the pyridine blue color-developing material is fed and dried through the drying mixing box 8, the built-in stirring blades 12 can spirally feed the material to avoid the accumulation of pyridine blue color-developing materials inside the drying mixing box 8, thereby improving the working efficiency of the pre-mixing chamber 6 and the double-cone vacuum drying barrel 2.

[0036] Please refer to Figure 1 and Figure 3 In this embodiment, the premixing assembly includes a drying rotary barrel 13 movably connected to the interior of the premixing chamber 6 , and a built-in stirring blade 12 is movably installed inside the drying rotary barrel 13 , and the stirring is driven by a servo motor 3 .

The pre-mixing chamber 6 is driven by the servo motor 3 to stir, and the raw materials can be loaded through the material port 5. The pre-mixing chamber 6 is in a vacuum state, and steam or hot water is introduced into the jacket for heating. The heat contacts the wet material through the inner wall of the barrel body. The water vapor evaporated after the wet material absorbs heat, and the pyridine blue color-developing material can be loaded and dried.

The drying rotary barrel 13 and the upper rotary blade 14 are movably installed inside the fixed feeding box 15. The pyridine blue color-developing material is added to the drying rotary barrel 13 and the upper rotary blade 14 through the material port 5, and is pre-mixed and dried. Then, it enters the double-cone vacuum drying barrel 2 through the fixed feeding box 15 to process the pyridine blue color-developing material. The double-cone vacuum dryer adopts two feeding structures.

[0040] As can be seen from the above, the pyridine blue color-developing material passes through the pre-mixing chamber 6 and the double-cone vacuum drying barrel 2. In the barrel, steam or hot water is introduced into the jacket for heating under vacuum. The heat contacts the wet material through the inner wall of the barrel. The water vapor evaporated after the wet material absorbs heat is pumped away through the vacuum exhaust pipe by the vacuum pump. At the same time, the pyridine blue color-developing material can be put into the feeding port 7. The pyridine blue color-developing material is added to the drying rotary barrel 13 and the upper rotary blade 14 through the feeding port 5 for pre-mixing and drying treatment, and then enters the double-cone vacuum drying barrel 2 through the fixed feeding box 15 for pyridine blue color-developing material treatment. The double-cone vacuum dryer adopts two feeding structures. The feeding port 7 and the feeding port 5 are respectively fixedly mounted on the double-cone vacuum drying barrel 2 and the pre-mixing chamber 6, and feeding can be carried out at the same time.

[0041] The pre-mixing motor 9 is movably installed in the dry mixing box 8 through the built-in stirring blades 12 for driving the drying process, and can feed and dry the pyridine blue color-developing materials. After the pyridine blue color-developing materials are dried, they are dried again through the pre-mixing chamber 6 and the double-cone vacuum drying barrel 2. After the pyridine blue color-developing materials are fed and dried through the dry mixing box 8, the built-in stirring blades 12 can spirally feed the materials to prevent the pyridine blue color-developing materials from accumulating inside the dry mixing box 8.
