Description

Technical Field

[0001] This invention conforms to the field of pneumatic conveying technology, and in particular, it mentions a pneumatic conveying refining agent device for aluminum molten metal refining. Background Technology

[0002] In the aluminum alloy smelting process, in order to remove hydrogen, inclusions, and some alkali metal impurities from the molten aluminum, it is usually necessary to add refining agents (such as hexachloroethane, fluoride salt mixtures, sodium-free refining agents, inert gas and chloride salt mixtures, etc.) to the melt and perform refining treatment. Currently, most of the refining agents are injected into the molten aluminum using pneumatic conveying equipment. The principle is to use compressed gas (inert gas) as a carrier to transport powdery materials. Since the refining agent is a dry powder material, it is very easy to absorb moisture and clump. In addition, during the gas transportation process, at pipe bends, valves, or spray gun outlets, the powdered refining agent will stick and deposit due to pressure and temperature changes, resulting in poor refining agent transportation or even complete blockage, which seriously affects the reliability of continuous equipment operation. At the same time, the clumped or deposited refining agent will prevent it from mixing evenly with the gas, resulting in uneven concentration distribution of gas and refining agent in the pipeline. The difference in the amount of refining agent carried per unit volume of gas is large, affecting the metering accuracy, dispersion effect, and reaction efficiency of the refining agent finally injected into the melt. Summary of the Invention

[0003] In order to overcome the shortcomings mentioned in the background art, the present invention provides a pneumatic conveying refining agent device for aluminum molten metal refining.

[0005] Furthermore, the gas injection mechanism includes: a gas guide pipe, which is fixedly connected to and passes through the processing tank; the gas guide pipe is connected to the gas supply module; a flow divider is provided inside the drive shaft; the gas guide pipe is connected to the flow divider via an mounting ring; the drive shaft is provided with gas outlets corresponding one-to-one with the number of disturbance shells; the gas outlets are connected to the flow divider; a transition channel is provided inside the disturbance shell; the transition channel is connected to the corresponding gas outlet; and a plurality of first holes are provided on one side of the disturbance shell, each of which is connected to the transition channel inside.

[0006] Furthermore, the interconnected area of ​​all the first holes on the same disturbance housing gradually increases from one side closer to the drive shaft to the other side.

[0007] Furthermore, the disturbance shell is inclined, and the first hole is located on the side of the disturbance shell with a larger side height.

[0008] Furthermore, the transition channel is composed of a first channel, a second channel, and a third channel, and the first channel, the second channel, and the third channel on the same transition channel are connected in sequence. The first channel is connected to the corresponding air outlet, and the third channel is connected to the corresponding first hole.

[0009] Furthermore, the drive shaft has a hollow structure, and the lower end of the drive shaft is located inside the discharge shell. The central axis of the drive shaft coincides with the central axis of the discharge shell, and the extension line of the central axis of the drive shaft intersects the midpoint of the connection line between the jet module and the spray module.

[0010] Furthermore, a heating module is installed on the processing tank, which is used to heat the air guide pipe.

[0011] Furthermore, it also includes: an auxiliary crushing mechanism, disposed on the drive shaft, for crushing the material entering the discharge shell. The auxiliary crushing mechanism includes: a first rod, consisting of several coils of different heights, all fixed to the drive shaft; and a second rod, consisting of several coils of different heights, all fixed to the discharge shell, with the second rod located between two adjacent coils of the first rod. Support rods are fixed to both the first rod and the second rod.

[0012] Furthermore, a bonding shell is fixedly attached to the disturbance shell, and the bonding shell is in contact with the inner wall of the processing barrel.

[0013] Furthermore, it also includes: an auxiliary cleaning mechanism, disposed inside the processing tank, for cleaning the material on the processing tank; the auxiliary cleaning mechanism includes: an electric push rod, fixedly connected inside the processing tank, with a transmission rod fixedly connected to the telescopic end of the electric push rod; connecting rings, the number of which is the same as the number of disturbance shells, all slidably connected inside the transmission shaft, adjacent connecting rings being fixedly connected by connecting rods, and the uppermost connecting ring slidingly limited to the transmission rod; symmetrically distributed extrusion frames fixedly connected to the connecting rings; sealing strips, the number of which is the same as the number of disturbance shells, slidably connected inside adjacent disturbance shells, the sealing strips being slidably connected to the corresponding extrusion frames; the bonding shell communicating with the transition channel of the disturbance shell; and the sealing strips controlling the communication state between the bonding shell and the disturbance shell; the bonding shell having several second holes.

[0014] The beneficial effects of this invention are as follows: By pretreating the refining agent in the processing tank, stirring it and injecting gas into it, the agglomerated refining agent is quickly dispersed, and the refining agent is made to have full contact with the gas. This reduces the probability of refining agent agglomeration and the probability of refining agent clogging the pipeline, thus ensuring the normal transportation of refining agent.

[0015] This invention heats the gas using a heating module, allowing the hot gas entering the processing tank to heat the refining agent, thereby increasing the dryness of the refining agent and facilitating its dispersion. Simultaneously, it preheats the refining agent, reducing the temperature difference between the refining agent and the molten aluminum, which facilitates the subsequent fusion of the refining agent and the molten aluminum.

[0016] This invention uses a bonding shell to scrape the inner wall of the processing barrel, causing the refining agent adhering to the inner wall of the processing barrel to fall off, reducing the residue of the refining agent in the processing barrel and improving the utilization rate of the refining agent. Furthermore, the bonding shell is used to blow hot gas to the inner wall of the processing barrel, further reducing the residue of the refining agent on the inner wall of the processing barrel.

Detailed Implementation

[0019] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] Please refer to the following: A pneumatic conveying and refining agent equipment for molten aluminum refining. Figures 1 to 5The device includes a frame 1, on which a gas supply module 2 is mounted. The gas supply module 2 provides inert gas (hereinafter referred to as gas). A processing tank 3 is fixedly connected to the frame 1. A discharge shell 4 is fixedly connected and connected to the lower side of the processing tank 3. A chamfered platform is provided in the lower part of the processing tank 3 to guide the material inside (the material mentioned in this application refers to refining agent), facilitating the material to enter the discharge shell 4. A jet module 5 is connected to the front side of the discharge shell 4. The jet module 5 is connected to the gas supply module 2 and is used to spray gas into the discharge shell 4 and impact the material. A spray module 6 is connected to the rear side of the discharge shell 4. The spray module 6 is used to discharge the mixture of gas and material. It includes: a fixed shell 7, fixedly connected to the processing tank 3; a drive shaft 8, rotatably connected to the fixed shell 7, with five pairs of disturbance shells 9 fixedly connected to the drive shaft 8. The disturbance shells 9 are used to stir the material, disperse the material, and facilitate full contact between the material and the gas. A drive module 10 is installed on the processing tank 3. The drive module 10 consists of a servo motor and a gear set, with the gear set located inside the fixed shell 7. The drive module 10 is used to drive the drive shaft 8 to rotate; a feed shell 11, fixedly connected to and connected to the processing tank 3. A manual control valve is installed inside the feed shell 11. The control valve is opened when material needs to be added and closed after quantitative injection is completed; and a gas injection mechanism, located inside the processing tank 3, for injecting gas into the disturbance shells 9.

[0022] Please see Figure 1 and Figures 5 to 8 The gas injection mechanism includes: a gas guide pipe 21, fixedly connected to and passing through the treatment tank 3; the gas guide pipe 21 is a flexible hose, and is connected to the gas supply module 2; a flow divider 22 is provided inside the drive shaft 8, and the gas guide pipe 21 is connected to the flow divider 22 through an mounting ring, which is rotatably connected to the drive shaft 8 and supports the gas guide pipe 21; the drive shaft 8 is provided with five pairs of gas outlets 23, each corresponding to a disturbance shell 9, and the gas outlets 23 are connected to the flow divider 22; a transition channel 24 is provided inside the disturbance shell 9, the transition channel 24 is serpentine, and the transition channel 24 is used to guide the gas entering the disturbance shell 9 and prolong the contact time between the gas and the disturbance shell 9; the transition channel 24 and the corresponding gas outlet... The air inlet 23 is connected, and five first holes 25 are provided on the side of the disturbance shell 9 opposite to its rotation direction. Each first hole 25 is connected to the internal transition channel 24. The first holes 25 are used to inject gas into the processing tank 3 and impact the material, which further facilitates the dispersion of the material. The connecting area of ​​all the first holes 25 on the same disturbance shell 9 gradually increases from the side closer to the drive shaft 8 to the other side. The setting of this connecting area is used to fully impact the material at different positions, which facilitates the dispersion of the material at different positions. The disturbance shell 9 is inclined to guide the material, and the first holes 25 are located on the side of the disturbance shell 9 with a larger side height, so that the gas is sprayed upward at an angle, following the upward movement trend of the gas, and ensuring the impact force on the material.

[0023] Please see Figure 3 , Figure 4 and Figure 7 The transition channel 24 consists of a first channel 241, a second channel 242, and a third channel 243. The first channel 241, the second channel 242, and the third channel 243 on the same transition channel 24 are sequentially connected. The first channel 241 is connected to the corresponding air outlet 23, and the third channel 243 is connected to the corresponding first hole 25. The drive shaft 8 has a hollow structure, and its lower end is located inside the discharge shell 4. The cavity inside the drive shaft 8 guides the gas in the processing tank 3, allowing the gas to be discharged from the lower part of the drive shaft 8 into the discharge shell 4. The central axis of the drive shaft 8 coincides with the central axis of the discharge shell 4. The gas discharged from the lower part of the drive shaft 8 interacts with the air jet. The gas discharged from module 5 impacts and promotes contact between the gas and the material, facilitating the dispersion of the material. The extension line of the central axis of the drive shaft 8 intersects the midpoint of the connection line between the jet module 5 and the material spraying module 6. A heating module 12 is installed on the processing tank 3. The heating module 12 is used to heat the gas guide pipe 21, thereby heating the gas flowing through the gas guide pipe 21, thus preheating the material in the processing tank 3 and reducing the temperature difference between the mixture and the molten aluminum. During the process of the gas flowing through the transition channel 24, the hot gas heats the disturbance shell 9, so that the disturbance shell 9 and the hot gas simultaneously heat the material in the processing tank 3, improving the dryness of the material.

[0024] Working principle: When it is necessary to inject materials into molten aluminum, a fixed amount of material is first taken out according to the specified mixing ratio. Then, the material is injected into the processing tank 3 through the feeding shell 11. The material in the processing tank 3 gradually moves downward and enters the discharge shell 4. After the material has completely entered the processing tank 3, the gas supply module 2, the drive module 10 and the heating module 12 are turned on. The gas supply module 2 injects gas into the discharge shell 4 through the jet module 5. The gas mixes with the material to form a mixture. The gas carries the material into the spray module 6 and is discharged from the spray module 6 into the molten aluminum, where it mixes with the molten aluminum.

[0025] After the drive module 10 is turned on, the drive 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 tank 3, so that the material is in a flowing state, reducing the probability of the material being compacted. At the same time, stirring disperses the clumps of material, making it easier for the subsequent material to come into full contact with the gas.

[0026] After the gas supply module 2 is turned on, it pumps gas into the gas guide pipe 21. During this process, the heating module 12 heats the gas flowing inside the gas guide pipe 21. After heating, the gas enters the transition channel 24 of all the disturbance shells 9 along the gas guide pipe 21, the diversion chamber 22 and all the gas outlets 23. 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 hole 25. The discharged gas impacts the material in the processing tank 3. The material is quickly dispersed after being impacted by the gas, and the heated gas preheats the material, improving the dryness of the material and reducing the occurrence of material re-agglomeration.

[0027] During the process of gas flowing through the transition channel 24, the heated gas heats the disturbance shell 9, so that the disturbance shell 9 heats the material simultaneously during the stirring process, thereby improving the uniformity of heating the material and ensuring full contact between the gas and the material.

[0028] During the above process, as the material is impacted by the gas and agitated by the disturbance shell 9, the material gradually disperses, the amount of agglomerated material decreases, and its own temperature gradually increases. With the operation of the jet module 5, the material in the discharge shell 4 is gradually discharged smoothly, while the material in the processing tank 3 gradually enters the discharge shell 4 and is smoothly discharged through the spray module 6.

[0029] During the process of gas impacting material in the processing tank 3, the gas passes through the material and moves upward. Then, the gas passes through the cavity in the middle of the drive shaft 8 and moves downward along the cavity. After that, this part of the gas enters the discharge shell 4 and impacts the mixture in the discharge shell 4, further improving the mixing degree of the material and gas, ensuring sufficient contact between the gas and the material, and facilitating the smooth discharge of the material.

[0030] After the material in the processing tank 3 is discharged, the air supply module 2, drive module 10 and heating module 12 continue to work for a fixed time (this time is set by the operator) to allow hot gas to enter the processing tank 3 and impact the remaining material in the processing tank 3, so as to facilitate the discharge of the remaining material in the processing tank 3, reduce the material residue in the processing tank 3, and ensure the full utilization of the material. Then the air supply module 2, drive module 10 and heating module 12 are turned off, and the operation ends.

[0031] Example 2

[0032] Based on Example 1, please refer to Figure 3 , Figure 4 and Figure 8It also includes: an auxiliary crushing mechanism, mounted on the drive shaft 8, for crushing the material entering the discharge shell 4. The auxiliary crushing mechanism includes: a first rod 31, consisting of several rings of different heights, with three rings in total, all fixed to the drive shaft 8. In this application, each ring of the first rod 31 contains three rods; and a second rod 32, consisting of several rings of different heights, with three rings in total, all fixed to the discharge shell 4. In this application, each ring of the second rod 32 contains three rods, and the second rod 32 is located between two adjacent rings of the first rod 31. Between 1, several support rods are fixedly connected to the first rod 31 and the second rod 32, which are distributed vertically. During the rotation of the drive shaft 8, the drive shaft 8 drives all the first rods 31 on it to rotate synchronously. The first rods 31 drive the support rods on them to rotate. Each rotation of the first rod 31 is relative to the second rod 32 of the adjacent rotation. During the process, the relatively rotating support rods work together to stir the material entering the discharge shell 4 and apply shear force to the material, which facilitates the dispersion of agglomerated material, ensures full contact between gas and material, and facilitates smooth discharge of material.

[0033] Example 3

[0034] Based on Example 2, please refer to Figure 2 , Figures 4 to 6 , Figure 8 and Figure 9 A bonding shell 41 is fixedly attached to the disturbance shell 9. The bonding shell 41 is a triangular prism and contacts the inner wall of the processing tank 3. The bonding shell 41 is used to scrape the inner wall of the processing tank 3, so that the material attached to it can fall off. During the rotation of the disturbance shell 9, the disturbance shell 9 drives the bonding shell 41 on it to rotate synchronously. The bonding shell 41 scrapes the inner wall of the processing tank 3, so that the material attached to the inner wall of the processing tank 3 falls off and into the discharge shell 4, reducing material waste and making full use of the material in the processing tank 3, and ensuring the accuracy of the refining agent ratio.

[0035] Example 4

[0036] Based on Example 3, please refer to Figures 6 to 11It also includes: an auxiliary cleaning mechanism, set inside the processing tank 3, used to clean the material on the processing tank 3. The auxiliary cleaning mechanism includes: an electric push rod 51, fixed inside the processing tank 3. The electric push rod 51 is an existing structure, and its internal principle is not described in detail. A dust cover can be set on its outside. The telescopic end of the electric push rod 51 is fixedly connected to a transmission rod 52. An annular groove is provided on the lower side of the transmission rod 52; and connecting rings 53, the number of which is the same as the number of pairs of the disturbance shell 9, with five arranged vertically, all slidably connected inside the transmission shaft 8. The connecting rings 53 are located inside the diversion cavity 22. Two adjacent connecting rings 53 are fixedly connected by two connecting rods. All connections Ring 53 can move up and down synchronously. The outer side of the uppermost connecting ring 53 is provided with an annular groove, and the uppermost connecting ring 53 slides and is limited by the lower side of the transmission rod 52. The annular groove on the uppermost connecting ring 53 engages with the annular groove on the lower side of the transmission rod 52. Two symmetrically distributed extrusion frames 54 are fixedly connected to the connecting ring 53. The extrusion frames 54 are provided with inclined grooves, and the distance between the inclined grooves on the two symmetrically distributed extrusion frames 54 gradually increases from top to bottom. The number of sealing strips 55 is the same as the number of disturbance shells 9, and they are slidably connected to the adjacent disturbance shells 9. The sealing strips 55 are provided with vent holes (such as...) on the side near the fitting shell 41. Figure 7 As shown), the sealing strip 55 is slidably connected to the inclined groove of the corresponding extrusion frame 54. The transition channel 24 of the bonding shell 41 and the disturbance shell 9 is connected. The sealing strip 55 is used to control the connection state between the bonding shell 41 and the disturbance shell 9. Initially, the first channel 241 is connected to the second channel 242 through the vent hole of the sealing strip 55. The sealing strip 55 blocks the connection between the bonding shell 41 and the disturbance shell 9. When it is necessary to clean the inner wall of the processing tank 3, the sealing strip 55 blocks the connection between the first channel 241 and the second channel 242 and connects the bonding shell 41 and the disturbance shell 9. The bonding shell 41 is provided with several vertically distributed second holes 42. A one-way valve (valve-type sealing valve) is provided in the second hole 42. The one-way valve is an existing structure, which is mainly an inverted hard film with a cross-shaped cut on its surface. The one-way valve mainly prevents the material from entering the bonding shell 41 along the second hole 42.

[0037] Working principle: During the stirring process of the material by the agitation shell 9, the electric push rod 51 is activated at regular intervals. 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. During this process, the upper connecting ring 53 drives the lower connecting ring 53 to move synchronously through the connecting rod. The connecting ring 53 drives the two extrusion frames 54 on it to move downward synchronously. The extrusion frames 54 extrude the sealing strip 55, causing the sealing strip 55 to move towards the middle of the processing tank 3 (the symmetrically distributed sealing strips 55 move in opposite directions). Sliding along the corresponding disturbance shell 9, the vent hole of the sealing strip 55 is half blocked by the disturbance shell 9, reducing the communication area between the first channel 241 and the second channel 242 by half, and connecting the first channel 241 with the bonding 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. The other part of the hot gas enters the bonding shell 41. The hot gas in the bonding shell 41 squeezes the corresponding valve-type sealing valve, causing it to open. That is, the hot gas enters the processing tank 3 through the corresponding second hole 42 and impacts the material near the inner wall of the processing tank 3, causing the material at that position to disperse.

[0038] When the telescopic end of the electric push rod 51 retracts, the telescopic end of the electric push rod 51 drives all the sealing strips 55 to reset through the transmission rod 52, all the connecting rings 53 and all the extrusion frames 54, so that the first channel 241 and the second channel 242 are fully connected, and the first channel 241 is disconnected from the bonding shell 41, so that the hot gas in the first channel 241 is discharged only from the corresponding first hole 25.

[0039] After the material is discharged from the processing tank 3, based on the workflow of Embodiment 1, during the continuous fixed time of operation of the gas supply module 2, drive module 10 and heating module 12, the telescopic end of the electric push rod 51 is fully extended, that is, the first channel 241 and the second channel 242 are no longer connected, and the first channel 241 is fully connected to the bonding shell 41. The hot gas in the first channel 241 completely enters the corresponding bonding shell 41 and is ejected from the corresponding second hole 42. In this way, the hot gas strongly impacts the inner wall of the processing tank 3, thereby facilitating the falling of the material attached to the inner wall of the processing tank 3 and reducing material waste.

[0040] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, the content of this specification should not be construed as a limitation of the present application.
