Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of smelting equipment, and in particular relates to a feeding device used for the preparation of aluminum-titanium-boron. Background Art
[0002] The raw materials for the preparation of aluminum titanium boron are usually potassium fluorotitanate and potassium fluoroborate, which are white powders. In the preparation of aluminum titanium boron, after the aluminum ingot is melted, potassium fluorotitanate and potassium fluoroborate are directly added to the surface of the aluminum liquid, reacting with aluminum on the surface, and easily accumulating on the surface of the aluminum liquid, resulting in a slow reaction speed. The second phase after the reaction cannot be well dispersed in the alloy, thereby affecting the second phase morphology and distribution uniformity of the aluminum titanium boron alloy, resulting in a decrease in the quality of aluminum titanium boron. At the same time, the reaction slag enters the alloy after electromagnetic stirring, causing the alloy purity to decrease, further affecting the quality of aluminum titanium boron.
[0003] Therefore, in order to improve the quality of aluminum titanium boron preparation, it is necessary to solve the problem of adding materials more fully during the aluminum titanium boron preparation process. Utility Model Content

[0043] Preferably, the second pipeline 8 includes a stainless steel pipe main pipe 19, a main tee pipe 20 arranged at one end of the stainless steel pipe main pipe 19 and a secondary tee pipe 21 arranged at the other end of the stainless steel pipe main pipe 19, the stainless steel pipe main pipe 19 is connected to the first pipeline 7 and the discharge rubber pipe 22 respectively through the main tee pipe 20, and the stainless steel pipe main pipe 19 is connected to the third pipeline 9 and the intake rubber pipe 23 respectively through the secondary tee pipe 21; the end of the discharge rubber pipe 22 is connected to the discharge titanium pipe 28.
[0044] Reference Figure 2 , by setting a stainless steel pipe main pipe 19 on the second pipeline 8, and connecting it with the first pipeline 7 through the main tee pipe 20, the material is discharged, and the corresponding valves are opened and closed for the discharge, so that the material is discharged from the first pipeline 7, the main tee pipe 20 and the discharge rubber pipe 22 in sequence, which has been explained in the above valve control principle; similarly, when feeding is required, the corresponding valves are opened and closed, so that the gas enters the bottom of the silo 1 from the intake rubber pipe 23, the auxiliary tee pipe 21 and the first pipeline 7 in sequence, and the material enters the main tee pipe 20 from the first pipeline 7. When potassium fluorotitanate and potassium fluoroborate need to be transported, the corresponding valves are controlled so that the high-pressure inert gas carries potassium fluorotitanate and potassium fluoroborate from the discharge rubber pipe 22 of the first pipeline 7 at the bottom of the silo, and is transported to the medium-frequency induction furnace and aluminum liquid for reaction; thus, the pipeline assembly 6 of the utility model effectively solves the problem of potassium fluorotitanate and potassium fluoroborate transportation, makes transportation smoother, and improves the convenience of operation and production efficiency.
[0045] As a preferred method of this embodiment, a discharge titanium tube 28 is connected to the end of the discharge rubber tube 22, and a titanium material pipe is used, which can be directly inserted into the high-temperature aluminum body. The titanium tube can realize high temperature resistance and corrosion resistance.

[0047] Reference Figure 1 Since the third pipeline 9 includes a rubber main pipe 24 and a rigid inner pipe 25, the rubber main pipe 24 and the rigid inner pipe 25 are connected to realize the transportation of potassium fluorotitanate and potassium fluoroborate by high-pressure inert gas; at the same time, the rigid inner pipe 25 is set as an "L"-shaped pipeline and placed in the silo 1, so that potassium fluorotitanate and potassium fluoroborate can be smoothly transported in the silo 1; at the same time, since the rubber main pipe 24 is connected to the silo 1 through the telescopic pipe 26, the position where the rubber main pipe 24 and the rigid inner pipe 25 are connected can be moved and controlled, thereby moving the rigid inner pipe 25 to a certain position in the silo 1, so that potassium fluorotitanate and potassium fluoroborate can be smoothly transported in the silo 1.
[0048] Preferably, the rigid inner tube 25 is connected to the rubber main tube 24, one end of the telescopic tube 26 is sealingly sleeved on the rubber main tube 24, and one end of the telescopic tube 26 is sealingly connected to the silo 1; the rigid inner tube 25 is movably placed at the connection between the telescopic tube 26 and the silo 1.
[0049] It can be understood that by connecting the rigid inner tube 25 with the rubber main tube 24, the rubber main tube 24 is flexibly connected to the silo 1 through the telescopic tube 26, and the rigid inner tube 25 is movably placed at the connection between the telescopic tube 26 and the silo 1, thereby realizing the transportation of potassium fluorotitanate and potassium fluoroborate to the silo 1 by the rubber main tube 24 and the rigid inner tube 25, and at the same time, the rigid inner tube 25 can be controlled inside the silo 1, so as to facilitate smoother transportation of potassium fluorotitanate and potassium fluoroborate in the silo 1.

[0051] It can be understood that by evenly distributing and fixing four support legs 27 on the outer wall of the silo 1, stable support for the silo 1 can be achieved. The reason is that during the transportation process, the operation of the high-pressure gas causes a certain vibration in the entire device; therefore, it is necessary to strengthen the support of the silo 1, which is beneficial to the stability of the system when it is in working condition.
[0052] The working principle and working process of this utility model:
[0053] The utility model provides a feeding device for the preparation of aluminum, titanium and boron. When working, a silo 1 having a barrel body 2 and a conical barrel 3 is provided to contain potassium fluorotitanate and potassium fluoroborate. At the same time, a pipeline assembly 6 is provided at the bottom of the conical barrel 3, and a high-pressure inert gas is transported through the pipeline assembly 6. More specifically, the third pipeline 9, the second pipeline 8 and the first pipeline 7 are connected, the first valve 10, the second valve 11 and the third valve 12 are opened, and the high-pressure inert gas enters the third pipeline 9, the second pipeline 8 and the first pipeline 7 from the air inlet pipe. The high-pressure gas entering the third pipeline 9 transports the potassium fluorotitanate and potassium fluoroborate in the silo through the rigid inner tube 25 to the discharge rubber tube 22, and then transports them to the aluminum liquid through the discharge titanium tube 28, so as to contact with the aluminum liquid and react fully.
[0054] After the feeding is completed, the third valve 12 and the first valve 10 are closed, and the second pipeline 8 is ventilated, that is, the air inlet rubber tube 23 is ventilated, and the aluminum liquid is continued to be ventilated, so as to stir the aluminum liquid and bring the reaction slag to the surface of the aluminum liquid, so as to facilitate pouring. Thus, potassium fluorotitanate and potassium fluoroborate are brought from the silo into the aluminum liquid of the medium frequency induction furnace by high-pressure inert gas for full contact, so that potassium fluorotitanate and potassium fluoroborate react fully, and the second phase of the reaction product is evenly distributed in the aluminum melt.
