Description

Technical Field

[0001] The utility model relates to the technical field of aluminate binder production, in particular to a high-efficiency mixing device in the production of high-purity aluminate binder. Background Art

[0002] High-purity aluminate binder is an important inorganic material with high melting point, good thermal stability and excellent corrosion resistance. These characteristics make it widely used in ceramics, glass, metallurgy and other fields. In the production of high-purity aluminate binder, generally through precise batching, ceramic grinding process is used for grinding to obtain ultra-fine powder raw materials with extremely high fineness and homogenization. Subsequently, it is separated by filter pressing, dried, and pressed into a raw material blank by automatic molding equipment, and then calcined in a tunnel kiln to finally obtain aluminate binder.

[0003] In actual production, the powder after the grinding wheel treatment often has the problem of large particles, which affects the growth of the crystal phase during the subsequent sintering; moreover, the existing technology mostly adopts the stirring mixing method, but directly stirring the mixing method has the problems of uneven mixing and low efficiency. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide an efficient mixing device for the production of high-purity aluminate binder. Through the arrangement of scrapers and filters, when the grinding wheel is working, the crushed powder is subjected to a rotational scraping treatment, so that larger particles are turned over to the top of the powder and can continue to be crushed, which greatly reduces the large particles entering the primary powder storage tank. At the same time, it also reduces the workload of the filter and avoids the large particles from entering the subsequent production. Through the coordinated use of the guide plate and the hemispherical disperser, a variety of materials can be properly mixed before stirring, which greatly improves the mixing efficiency and the uniformity of the mixing.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The high-efficiency mixing device for the production of high-purity aluminate binder is characterized in that it includes a rolling crusher connected to a primary filter through a primary powder storage tank, the primary filter is connected to a ball press through a mixing box, a rolling wheel driven by a driving motor is provided inside the rolling crusher, a hemispherical disperser is provided inside the mixing box, and a material guide plate is provided above the hemispherical disperser.

[0007] The driving motor is connected to the rolling wheel through a connecting rod, a scraper is connected to the connecting rod, and the scraper and the rolling wheel are in the same horizontal plane.

[0008] The high-efficiency mixing device in the production of high-purity aluminate binder also includes a secondary powder storage tank, which is connected to the mixing box through a secondary filter.

[0009] The filter includes a primary filter and a secondary filter.

[0010] The interior of the primary filter is provided with an inclined filter screen, and the outer side of the vertical wall of the primary filter is provided with an impurity discharge port and a vibrator.

[0011] A first-stage filter discharge pipe is provided between the first-stage filter and the mixing box, and a second-stage filter discharge pipe is provided between the second-stage filter and the mixing box.

[0012] The connection between the discharge pipe of the primary filter and the mixing box is located above the guide plate, and the connection between the discharge pipe of the secondary filter and the mixing box is located above the guide plate.

[0013] The raw materials entering the mixing box from the secondary filter discharge pipe and the primary filter discharge pipe are first mixed at the scraper. The barrier column increases the possibility of collision between various powders, and then fall onto the hemispherical disperser. The hemispherical disperser is used to increase the dispersion of the raw materials entering the mixing box at different times to improve the mixing rate.

[0014] The mixing box is provided with a stirring paddle driven by a stirring motor, a material guide plate is provided with a barrier column, and the mill crusher is connected with an induced draft fan.

[0015] The working principle of the utility model is:

[0016] After the block material enters the roller crusher, the driving motor drives the roller and the scraper to start rotating, and the induced draft fan starts. The processed powder enters the primary powder storage tank, and then enters the mixing box after being filtered by the primary filter. The powder in the secondary powder storage tank enters the mixing box after being processed by the secondary filter. The raw materials entering the mixing box are first mixed at the scraper. When passing through the barrier column, the barrier column increases the collision of various powders. Then they fall to the hemispherical disperser. The hemispherical disperser increases the dispersion of the raw materials entering the mixing box at different times. The stirring motor drives the stirring paddle to start rotating. After the mixing is completed, it enters the ball press. Among them, the filter includes a primary filter and a secondary filter. The raw materials entering the mixing box from the secondary filter outlet pipe and the primary filter outlet pipe are first mixed at the scraper. The barrier column increases the possibility of collision of various powders. Then they fall to the hemispherical disperser. The hemispherical disperser is to increase the dispersion of the raw materials entering the mixing box at different times to increase the mixing rate.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] By adopting the high-efficiency mixing device in the production of high-purity aluminate binder of the utility model, through the arrangement of the scraper and the filter, when the grinding wheel is working, the rolled powder is subjected to a rotational scraping treatment, so that larger particles are turned over to the top of the powder body and can continue to be rolled, which greatly reduces the large particles entering the primary powder storage tank. At the same time, it also reduces the workload of the filter and avoids the large particles from entering the subsequent production; through the coordinated use of the guide plate and the hemispherical disperser, a variety of materials can be properly mixed before stirring, which greatly improves the mixing efficiency and the uniformity of the mixing.
