Description
Technical Field
[0001] The utility model relates to the technical field of mica powder preparation devices, in particular to a drying device for preparing ultrafine mica powder. Background Art
[0002] Mica powder is a non-metallic mineral containing a variety of components, mainly SiO2, which is generally about 49% and Al2O3 about 30%. Mica powder has good elasticity and toughness. It is an excellent additive with the characteristics of insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, and strong adhesion. In the process of preparing mica powder, the mica powder needs to be ground and dried at the same time to facilitate the subsequent use of the mica powder. In order to improve the drying efficiency of the mica powder, the mica powder will be placed inside the drying box for drying.
[0003] When the mica powder drying device is used, the mica powder is first transported to the inside of the drying box. In order to improve the uniformity of the mica powder during drying, a stirring device is usually installed inside the drying box. The stirring device can drive the mica powder to be stirred, thereby improving the uniformity of the mica powder when receiving heat, thereby improving the sufficiency of the mica powder when mixed and dried. However, this drying device can only control a part of the mica powder for drying treatment in sequence, and cannot drive the mica powder to be dried continuously, which reduces the drying efficiency of the mica powder. For this reason, we propose a drying device for preparing ultrafine mica powder. Utility Model Content

A spring 14 is sleeved on the outside of the movable column 13. The spring 14 pushes the sealing plate 11 to move to the outside of the limiting sleeve 10. At the same time, the sealing plate 11 stops blocking the lower end of the conical tube 2. A first connecting rope 15 is fixedly connected to one end of the sealing plate 11. A first circular sleeve 16 is fixedly connected to the lower end of the conical tube 2. A second circular sleeve 17 and a third circular sleeve 18 are movably sleeved on the lower end of the conical tube 2. When the three circular sleeves 18 rotate, the third circular sleeve 18 drives the second circular sleeve 17 to rotate and move by friction, and at the same time, the second circular sleeve 17 drives the first connecting rope 15 to stretch to one side. The inner side of the third circular sleeve 18 is fixedly connected to the second connecting rope 19, and the outer side of the first circular sleeve 16 is fixedly connected to the protective sleeve 20, which limits the moving trajectory of the second circular sleeve 17. The upper end of the interior of the drying box 1 is fixedly connected to the discharge pipe 21, and the discharge pipe 21 drives the mica powder to be transported to the interior of the drying box 1.
[0025] See also Figure 4Five groups of scrapers 5 are installed inside the drying box 1.

[0026] See also Figure 4 The scraper 5 and the push plate 6 are arranged in the same plane, and the scraper 5 and the push plate 6 are arranged at an interval with each other. There is a two-millimeter gap between the push plate 6 and the rotating column 4. The scraper 5 and the push plate 6 are fixedly connected to the outside of the rotating column 4 by the scraper 5 and the push plate 6. At the same time, the lower end of the rotating column 4 is attached to the outside of the drying plate 3.

At the same time, the push plate 6 is arranged on the upper part of the drying plate 3. The push plate 6 can drive the mica powder to be scraped and leveled, and then the mica powder accumulated on the upper part of the drying plate 3 can be evenly distributed, thereby improving the uniformity of the mica powder when it is dried on the upper part of the drying plate 3 and improving the drying efficiency.
[0027] See also Figure 2 The interior of the conical tube 2 is conical, and the exterior of the second stirring rod 9 is attached to the inner wall of the conical tube 2.

At the same time, the first stirring rod 8 and the second stirring rod 9 are installed at the lower end of the rotating column 4. The first stirring rod 8 and the second stirring rod 9 can stir the mica powder accumulated inside the conical tube 2.
[0028] See also Figure 6 The two sides of the sealing plate 11 are movably sleeved inside the limiting sleeve 10. The sealing plate 11 is located at the lower end of the conical tube 2 where the discharge hole is opened. The sealing plate 11 is movably sleeved inside the limiting sleeve 10, and the limiting sleeve 10 limits the movement trajectory of the sealing plate 11. At the same time, a discharge hole is opened at the lower end of the conical tube 2. When the sealing plate 11 moves to the rear end, the discharge port can drive the material to slide downward, thereby improving the function of closing or opening when collecting mica powder.
[0029] See also Figure 6A limiting sleeve is installed on the side of the limiting sleeve 10, and the movable column 13 is movably sleeved inside the limiting sleeve. The spring 14 is installed between the connecting plate 12 and the limiting sleeve. The connecting plate 12 is installed on the side of the limiting sleeve 10. When the front end of the sealing plate 11 is reduced to a limit, the connecting plate 12 can control the sealing plate 11 to move to the rear end under the elastic action of the spring 14, and at the same time drive the interior of the limiting sleeve 10 to be opened.

Then, when driving the mica powder to dry, the sealing plate 11 can be controlled to move toward the inside of the limiting sleeve 10, and then the lower end of the conical tube 2 is sealed to improve the sealing of the mica powder when it is dried inside the drying box 1. After the drying is completed, the rotating column 4 stops rotating, and the mica powder can slide down through the outlet at the lower end of the conical tube 2.
[0031] Working principle: When in use, the mica powder is transported to the inside of the drying box 1 through the discharge pipe 21, and the drying plate 3 installed inside the drying box 1 limits the mica powder, and the rotating column 4 is started at the same time. The rotating column 4 drives the scraper 5 and the push plate 6 to rotate, and the scraper 5 drives the mica powder to move to the lower end. At the same time, the push plate 6 pushes the mica powder to level it, so as to improve the uniformity of the mica powder during drying. The heating device installed inside the drying plate 3 can dry the mica powder, and the mica powder is sequentially transported to the inside of the drying plate 3 installed at the lower end after drying, so as to improve the uniformity of the mica powder during drying. The reserved time of mica powder inside the drying box 1 improves the drying efficiency, and the rotating column 4 rotates. Under the action of the rotational force, it can drive the second circular sleeve 17 to rotate to one side by a certain angle, and at the same time, the second circular sleeve 17 can drive the first connecting rope 15 to shrink inward, and the sealing plate 11 seals the interior of the limiting sleeve 10. When the mica powder is dried, the rotating column 4 stops rotating, and at the same time, the sealing plate 11 is pushed to one side under the elastic action of the spring 14, and then the sealing plate 11 drives the lower end of the conical tube 2 to form an opening, and then the mica powder can be automatically discharged.
