Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy refining, deslagging and degassing, and in particular to a deslagging and degassing device for casting aluminum alloy refining and a process thereof. Background Art

[0002] Aluminum alloy refers to an alloy material made of aluminum metal as the main material mixed with some other metal materials. It has the advantages of low density, good thermal conductivity, electrical conductivity, and easy forming. In order to improve the performance of aluminum alloy materials, aluminum alloys are usually refined;

[0003] Aluminum alloy produces a lot of impurity slag and waste gas during the refining process, so slag removal and degassing equipment is usually used to discharge the impurity slag and waste gas;

[0004] The existing slag removal and degassing device still has the following shortcomings when in use:

[0005] 1. Existing devices usually only use simple filtration to remove impurity slag. This removal method has poor slag removal effect. Part of the impurity slag melted into the aluminum alloy refined liquid cannot be removed, and the slag removal is not thorough enough.

[0006] 2. The existing device only uses shaking and stirring to exhaust when treating waste gas. This exhaust method cannot discharge the waste gas dissolved in the aluminum alloy refined liquid, and the waste gas removal effect is poor, which has certain limitations.

[0007] Therefore, it is urgent to design a slag removal and degassing device for refining cast aluminum alloy and a process thereof to solve the above problems.

Summary of the Invention

A plurality of reciprocating tubes are fixedly installed on the lifting plate, and a separation filter membrane is fixedly installed in each reciprocating tube. An air guide mechanism is installed between the air filter box and the processing box, and a drain pipe is fixedly installed between the air filter box and the processing box.

[0013] In the above-mentioned deslagging and degassing device for refining cast aluminum alloy and its process, the stirring mechanism includes a fixed wheel fixedly mounted on the driving shaft, a stirring main rod fixedly mounted on the fixed wheel through a reciprocating spring rod, and a plurality of stirring sub-rods fixedly mounted on the stirring main rod.

[0014] In the above-mentioned slag removal and degassing device for refining cast aluminum alloy and its process, the unloading mechanism includes a stepped guide plate fixedly installed in a mixing barrel, and a screening filter plate is fixedly installed between the stepped guide plate and the mixing barrel, a down-liquid pipe and a down-slag pipe are fixedly installed between the screening filter plate and the mixing barrel, and electric valves are fixedly installed in the down-liquid pipe and the down-slag pipe, a liquid guide pipe is fixedly installed on the air filter box, and an elastic liquid pipe is fixedly installed between the liquid guide pipe and the down-liquid pipe, a slag discharge pipe is fixedly installed on the processing box, and an elastic guide tube is fixedly installed between the slag discharge pipe and the down-slag pipe.

[0015] In the above-mentioned slag removal and degassing device for refining cast aluminum alloy and its process, the rotating mechanism includes a connecting pipe fixedly installed in the heat conduction box, a sealing disk is slidably installed in the connecting pipe, a transmission gear rod is fixedly installed on the sealing disk through a connecting frame, and an outer gear ring matching the transmission gear rod is fixedly installed on the mixing barrel.

[0016] In the above-mentioned deslagging and degassing device for refining cast aluminum alloy and its process, the lifting mechanism includes a reciprocating screw fixedly mounted on the driving shaft, a ball nut plate is mounted on the reciprocating screw, and the lifting plate is fixedly mounted on the ball nut plate.

[0017] In the above-mentioned slag removal and degassing device for refining cast aluminum alloy and its process, the air guide mechanism includes an air guide pipe fixedly installed between the air filter box and the top plate, an air purification plate is fixedly installed in the processing box, and the air purification plate is located on the upper part of the top plate, and an exhaust pipe is fixedly installed on the processing box.

[0018] In the above-mentioned deslagging and degassing device for refining cast aluminum alloy and its process, a bottom plate is fixedly installed in the processing box, a plurality of support frames are fixedly installed outside the processing box, and a cleaning scraper is fixedly installed on each of the stirring main rods.

[0019] A construction process for a deslagging and degassing device for refining cast aluminum alloys comprises the following steps:

[0020] S1. When performing the slag and degassing work of the aluminum alloy refined liquid, the aluminum alloy refined liquid can be first introduced into the mixing barrel in the processing box through the feed pipe to complete the introduction of the aluminum alloy refined liquid;

[0021] S2. Restart the servo motor to drive the driving shaft to rotate. The driving shaft rotation drives the multiple fixed wheels on it to rotate. The fixed wheels rotation drives the stirring main rod and multiple stirring auxiliary rods to rotate, so that the aluminum alloy refined liquid can be fully stirred and the impurities and slag in the aluminum alloy refined liquid can be fully screened out.

[0022] S3. When the aluminum alloy refined liquid is stirred, the heating plate can be started to fully heat the aluminum alloy refined liquid in stages, and the impurity slag melted in the aluminum alloy refined liquid is removed in sequence by gradually increasing the amount of aluminum alloy refined liquid;

[0023] S4. When the aluminum alloy refined liquid is heated, the temperature inside the stirring barrel is transferred to the heat-conducting gas in the heat-conducting box. When heated, the heat-conducting gas expands and increases in volume and enters the connecting pipe, thereby pushing the sealing disk, the connecting frame and the transmission gear rod to move. The movement of the transmission gear rod pushes the outer gear ring meshed with it to rotate, thereby driving the stirring barrel and the aluminum alloy refined liquid inside to rotate as a whole, thereby adjusting the contact position between the aluminum alloy refined liquid and the stirring main rod and stirring auxiliary rod, further increasing the stirring and mixing efficiency and improving the slag removal effect;

[0024] S5. After the slag removal work is completed, the electric valve in the lower liquid pipe can be opened. At this time, the aluminum alloy refined liquid will be conducted to the air filter box through the lower liquid pipe, the elastic liquid pipe, and the liquid guide pipe, while the impurity slag will be blocked by the screening filter plate and remain on the step guide plate. Then the electric valve in the lower slag pipe is opened, and the impurity slag on the step guide plate will be discharged to the outside of the processing box through the lower slag pipe, the elastic guide pipe, and the slag discharge pipe;

[0025] S6. The aluminum alloy refined liquid entering the air filter box will fall onto the lifting plate and flow back and forth through the separation filter membranes in the multiple reciprocating tubes on it. When the driving shaft rotates, it will drive the reciprocating screw to rotate. The rotation of the reciprocating screw will drive the ball nut plate that cooperates with it to move up and down, thereby driving the lifting plate and the reciprocating tube to move up and down. When the separation filter membranes in the reciprocating tubes move up and down, they will repeatedly come into contact and squeeze with the aluminum alloy refined liquid, thereby fully squeezing out the waste gas in the aluminum alloy refined liquid. After the waste gas is refined, the aluminum alloy refined liquid will be discharged through the drain pipe;

[0026] S7. The waste gas extracted from the aluminum alloy refined liquid will go up to the upper part of the top plate through the air duct and come into contact with the air purification plate (which may be composed of activated carbon components). The air purification plate will perform preliminary purification and adsorption on the waste gas. After the adsorption of the waste gas, the waste gas can be discharged to the outside of the processing box through the exhaust pipe.

[0027] Compared with the existing technology, the advantages of the present invention are:

[0028] 1: By setting a stirring main rod and a stirring auxiliary rod, the stirring main rod and multiple stirring auxiliary rods rotate in coordination, so that the aluminum alloy refined liquid can be fully stirred, and the impurity slag in the aluminum alloy refined liquid can be fully screened out.

[0029] 2: By setting up a heating plate, when the aluminum alloy refined liquid is stirred, the heating plate can be started to fully heat the aluminum alloy refined liquid in stages, and the impurity slag melted in it can be removed in sequence by gradually increasing the aluminum alloy refined liquid.

[0030] 3: By setting up a rotating mechanism, when the aluminum alloy refined liquid is heated, the temperature inside the stirring barrel will be transferred to the heat-conducting gas in the heat-conducting box. The heat-conducting gas will expand and increase when heated, and with the cooperation of the rotating mechanism, it will drive the stirring barrel and the aluminum alloy refined liquid to rotate as a whole. The contact position between the aluminum alloy refined liquid and the stirring main rod and stirring auxiliary rod can be adjusted, further increasing the stirring and mixing efficiency and improving the slag removal effect.

[0031] 4: By setting up a lifting mechanism, the rotation of the driving shaft will drive the reciprocating screw to rotate, and the rotation of the reciprocating screw will drive the ball nut plate that cooperates with it to move up and down, thereby driving the lifting plate to move back and forth to increase the contact range with the aluminum alloy refined liquid, thereby increasing the effect of removing exhaust gas.

[0032] 5: By setting up a separation filter membrane, the reciprocating lifting of the lifting plate will drive the separation filter membrane in the reciprocating tube to move up and down and repeatedly contact and squeeze with the aluminum alloy refined liquid, so that the waste gas in the aluminum alloy refined liquid can be fully pressed out. After the waste gas is refined, the aluminum alloy refined liquid will be discharged through the drain pipe.

[0033] In summary, the present invention can increase the discharge effect of waste slag in aluminum alloy refined liquid by adopting repeated stirring and step-by-step heating, and can better discharge the waste gas in aluminum alloy refined liquid by adopting reciprocating separation extrusion, and the slag removal and degassing effects are better.

[0054] A construction process for a deslagging and degassing device for refining cast aluminum alloys comprises the following steps:

[0055] S1. When performing the deslagging and degassing work of the aluminum alloy refined liquid, the aluminum alloy refined liquid can be first introduced into the stirring barrel 6 in the processing box 1 through the feeding pipe 7 to complete the introduction work of the aluminum alloy refined liquid;

[0056] S2. Restart the servo motor 3 to drive the driving shaft 5 to rotate. The rotation of the driving shaft 5 will drive the multiple fixed wheels 8 thereon to rotate. The rotation of the fixed wheels 8 will drive the stirring main rod 20 and the multiple stirring auxiliary rods 9 to rotate, so that the aluminum alloy refined liquid can be fully stirred and the impurity slag in the aluminum alloy refined liquid can be fully screened out;

[0057] S3. When the aluminum alloy refined liquid is stirred, the heating plate 10 may be started to heat the aluminum alloy refined liquid in stages, and the impurity slag melted therein may be removed in sequence by gradually increasing the amount of aluminum alloy refined liquid;

[0058] S4. When the aluminum alloy refined liquid is heated, the temperature inside the stirring barrel 6 is transferred to the heat-conducting gas in the heat-conducting box 28. When heated, the heat-conducting gas expands and increases in volume and enters the connecting pipe 31, thereby pushing the sealing disk, the connecting frame 32 and the transmission gear rod 30 to move. The movement of the transmission gear rod 30 pushes the outer gear ring 29 meshing therewith to rotate, thereby driving the stirring barrel 6 and the aluminum alloy refined liquid inside to rotate as a whole, thereby adjusting the contact position between the aluminum alloy refined liquid and the stirring main rod 20 and the stirring auxiliary rod 9, further increasing the stirring and mixing efficiency and improving the slag removal effect;

[0059] S5. After the slag removal work is completed, the electric valve in the lower liquid pipe 23 can be opened. At this time, the aluminum alloy refined liquid will be conducted to the air filter box 12 through the lower liquid pipe 23, the elastic liquid pipe, and the liquid guide pipe 27, while the impurity slag will be blocked by the screening filter plate 11 and remain on the stepped guide plate 24. Then, the electric valve in the lower slag pipe 25 is opened, and the impurity slag on the stepped guide plate 24 will be discharged to the outside of the processing box 1 through the lower slag pipe 25, the elastic guide pipe 26, and the slag discharge pipe 19;

[0060] S6. The aluminum alloy refined liquid entering the air filter box 12 will fall onto the lifting plate 14 and reciprocate through the separation filter membranes in the multiple reciprocating tubes 33 thereon. When the driving shaft 5 rotates, it will drive the reciprocating screw 13 to rotate. The rotation of the reciprocating screw 13 will drive the ball nut plate 34 matched with it to move up and down, thereby driving the lifting plate 14 and the reciprocating tubes 33 to move up and down. When the separation filter membranes in the reciprocating tubes 33 move up and down, they will repeatedly contact and squeeze the aluminum alloy refined liquid, thereby fully squeezing out the waste gas in the aluminum alloy refined liquid. After the waste gas is refined, the aluminum alloy refined liquid will be discharged through the drain pipe 18.

[0061] S7. The waste gas extracted from the aluminum alloy refined liquid will go up to the upper part of the top plate through the air guide pipe 15 and will come into contact with the air purification plate 16 (which may be composed of activated carbon components). The air purification plate 16 will perform preliminary purification and adsorption on the waste gas. After the adsorption of the waste gas, the waste gas can be discharged to the outside of the processing box 1 through the exhaust pipe 17.

[0062] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
