Description

Technical Field

[0001] The utility model relates to the technical field of mixer equipment, and particularly discloses an externally-enclosed drying mixer. Background Art

[0002] The main function of a blender is to promote uniform mixing of substances. A rotating stirring rod is provided inside the blender, which mixes and stirs the substances in the blender to ensure that the substances in the blender reach the best mixing state, thereby improving product quality. In addition, the blender can ensure that the reaction between different substances is more uniform and more complete, thereby improving the accuracy of the ratio of the mixed substances and production efficiency.

[0003] Currently, to increase the turnover rate of raw materials, raw material pellets are typically stored in a factory's storage area. Due to the presence of other processing equipment in the factory, air humidity in the factory is difficult to control. If raw material pellets are left in the factory for extended periods, they are susceptible to moisture, resulting in high humidity and low temperatures. When the cool raw material pellets are placed in a blender to be mixed with other particles and a solution, the raw material pellets cannot be fully mixed with the solution in a short period of time, requiring the blender to operate for a longer period of time. This, in turn, lengthens the time required to achieve uniform mixing of the raw materials, significantly impacting production efficiency. Utility Model Content

[0004] In view of the problem that when a mixer is currently used to mix raw material particles, the surface temperature of the raw material particles is relatively low, resulting in a long time for the raw material particles to be mixed evenly and low production efficiency, the utility model provides an externally-enclosed drying mixer.

[0023] Among them, the drainage tube 12 is a conical structure and the cross-sectional area of ​​the inlet end is larger than the cross-sectional area of ​​the outlet end; by setting up the conical structure, the flow velocity of the raw material particles after entering the drainage tube 12 can be further improved, thereby increasing the flow rate of the raw material particles.

[0030] The operator can put the product raw material particles and mixed solution into the inner cavity of the cylinder 2 through the drainage tube 12, the insulation tube 11, and the feed pipe 3 in sequence, and pass the hot steam into the first air inlet pipe 4. The raw material particles can initially contact with the hot steam, thereby increasing the surface temperature of the raw material particles. The raw material particles pass through the inner side of the isolation cover 8 and fall into the storage hopper 23. The thermometer 17 can measure the inner cavity temperature of the cylinder 2 in real time through the temperature probe 18. If the inner cavity temperature of the cylinder 2 is lower than the predetermined value, hot steam is introduced into the inner side of the isolation cover 8 through the second air inlet pipe 9 and the third air inlet pipe 10, thereby raising the temperature of the inner cavity of the cylinder 2. When the temperature of the inner cavity of the cylinder 2 reaches the predetermined value, the temperature controller 19 can transmit a start signal to drive the driving motor 15 to drive the stirring rod 6 to rotate. After all the raw material particles and the mixed solution are put in, the liquid level of the mixed solution is higher than the rotor 7 and lower than the third air inlet pipe 10. The paddle 22 on the outside of the rotor 7 at the bottom end of the stirring rod 6 will fully stir the raw material particles and the mixed solution to make them fully and evenly mixed.
