Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pneumatic conveying, and particularly relates to an aluminum melt refining pneumatic conveying refining agent device. BACKGROUND

[0002] In the process of aluminum alloy smelting, in order to remove hydrogen, inclusions and part of alkali metal impurities in the aluminum melt, it is usually necessary to add refining agents (such as hexachloroethane, fluorine salt mixture, sodium-free refining agent, inert gas and chlorine salt mixture, etc.) into the melt and perform refining treatment. At present, the refining agent is usually injected into the aluminum melt by using a pneumatic conveying device. The principle is to use compressed gas (inert gas) as a carrier to convey the powder and particle materials. Since the refining agent is a dry powder material, it is easy to absorb moisture and form clumps. In the process of gas conveying, the powder refining agent is caused to adhere and deposit at the pipe bend, valve or spray gun outlet due to changes in pressure and temperature, thereby causing poor conveying of the refining agent or even complete blockage, which seriously affects the continuous operation reliability of the equipment. At the same time, the clumped or deposited refining agent cannot be uniformly mixed with the gas, which causes uneven distribution of the concentration of the gas and the refining agent in the pipeline, large difference in the amount of refining agent carried by unit volume of gas, and affects the metering accuracy, dispersion effect and reaction efficiency of the refining agent finally sprayed into the melt.

[0034] Working principle:

[0035] When it is needed to inject the material into the aluminum water, first, a certain amount of material is taken out according to the specified mixing ratio, then the material is injected into the processing barrel 3 through the feeding shell 11, the material in the processing barrel 3 gradually moves downward and enters the discharge shell 4, after the material completely enters the processing barrel 3, the air supply module 2, the driving module 10 and the heating module 12 are started, the air supply module 2 injects the gas into the discharge shell 4 through the air injection module 5, the gas mixes with the material to form a mixture, the gas carries the material into the material injection module 6, and then is discharged from the material injection module 6 into the aluminum water and mixes with the aluminum water.

[0036] After the driving module 10 is started, the driving module 10 drives all the disturbance shells 9 to rotate through the transmission shaft 8, the disturbance shells 9 stir the material in the processing barrel 3, so that the material is in a flowing state, the probability of the material being compacted is reduced, and the caked material is dispersed at the same time, so as to facilitate the subsequent material to fully contact with the gas.

[0037] After the gas supply module 2 is turned on, the gas supply module 2 pumps the gas into the gas guide pipe 21, in the process, the heating module 12 heats the gas flowing in the gas guide pipe 21, and then the heated gas enters the transition passage 24 of all the disturbance shells 9 along the gas guide pipe 21, the distribution cavity 22 and all the gas outlets 23, and then the gas flows along the first channel 241, the second channel 242 and the third channel 243 and is discharged from the corresponding first holes 25. The discharged gas impacts the material in the processing barrel 3, the material is quickly dispersed after being impacted by the gas, and the heated gas preheats the material, improves the drying degree of the material, and reduces the occurrence of material reblocking.

[0038] In the process of the gas flowing through the transition passage 24, the heated gas heats the disturbance shell 9, so that the disturbance shell 9 synchronously heats the material during stirring the material, improves the uniformity of heating the material, and ensures sufficient contact between the gas and the material.

[0039] In the above process, as the material is impacted by the gas and agitated by the disturbance shell 9, the material is gradually dispersed, the blocked material is reduced, and the temperature of the material itself gradually rises. Accompanied by the work of the gas injection module 5, the material in the discharge shell 4 is gradually and smoothly discharged, and at the same time, the material in the processing barrel 3 gradually enters the discharge shell 4 and is smoothly discharged by the material injection module 6.

[0040] In the process of the gas impacting the material in the processing barrel 3, the gas passes through the material and moves upward, and then the gas passes through the cavity in the middle of the transmission shaft 8 and moves downward along the cavity. Then, the part of the gas enters the discharge shell 4 and forms an impact with the mixture in the discharge shell 4, further improving the mixing degree of the material and the gas, ensuring sufficient contact between the gas and the material, and facilitating the smooth discharge of the material.

[0041] After the material in the processing barrel 3 is discharged, the gas supply module 2, the driving module 10 and the heating module 12 continue to work for a fixed time (which is set by the operator), so that the hot gas enters the processing barrel 3 and impacts the residual material in the processing barrel 3, facilitating the discharge of the remaining material in the processing barrel 3, reducing the residual material in the processing barrel 3, ensuring the full use of the material, and then turning off the gas supply module 2, the driving module 10 and the heating module 12, and ending this operation.

Initially, the first channel 241 is in communication with the second channel 242 through the ventilation hole of the sealing strip 55, and the sealing strip 55 blocks the communication between the abutting shell 41 and the disturbance shell 9. When it is necessary to clean the inner wall of the processing barrel 3, the sealing strip 55 blocks the communication between the first channel 241 and the second channel 242, and the abutting shell 41 is in communication with the disturbance shell 9. The abutting shell 41 is provided with a plurality of second holes 42 arranged vertically, and a one-way valve (valve type sealing valve) is arranged in the second hole 42.

The one-way valve mainly prevents the material from entering the abutting shell 41 along the second hole 42.

[0048] Working principle:

[0049] In the process of stirring the material by the disturbance shell 9, the electric push rod 51 is opened at a fixed time, the telescopic end of the electric push rod 51 extends downward and drives the transmission rod 52 to move downward (at this time, the telescopic end of the electric push rod 51 only extends half of its length), the transmission rod 52 drives the uppermost connecting ring 53 to move, in the process, the upper connecting ring 53 drives the lower connecting ring 53 below it to move synchronously through the connecting rod, the connecting ring 53 drives the two extrusion frames 54 above it to move downward synchronously, the extrusion frames 54 extrude the blocking strip 55, so that the blocking strip 55 moves to the middle of the processing barrel 3 (the symmetrically distributed blocking strips 55 move towards each other), the blocking strip 55 slides along the corresponding disturbance shell 9, the vent hole of the blocking strip 55 is blocked by the disturbance shell 9 by half, so that the communication area of the first channel 241 and the second channel 242 is reduced by half, and the first channel 241 is in communication with the fitting shell 41, at this time, part of the hot gas in the first channel 241 continues to flow along the second channel 242 and the third channel 243, and is discharged from the corresponding first hole 25, and the other part of the hot gas enters the fitting shell 41, the hot gas in the fitting shell 41 extrudes the corresponding valve type sealing valve to open, that is, the hot gas enters the processing barrel 3 through the corresponding second hole 42, and impacts the material close to the inner wall of the processing barrel 3, so that the material at this position is dispersed.
