Description

Technical Field

[0001] The present invention relates to an aluminum alloy casting preparation device, in particular to an aluminum alloy casting preparation device applied in the field of aluminum alloy casting preparation. Background Art

[0002] Aluminum alloys are often produced by casting. During casting, refiners are used to control the refined structure of the cast alloy and affect the forging structure. Aluminum-titanium-boron master alloy is one of the most important refiners for refining the aluminum alloy structure. Aluminum-titanium-boron refiners mainly play a refining role for TiAl3 and TiB2 particles.

[0003] For example, the specification of patent application number CN201910216660.6 discloses a device for preparing aluminum alloy castings. During use, the device first mixes pure aluminum powder, pure titanium powder and titanium borohydride powder evenly as a refiner, and the refiner mixed powder is preheated at high temperature to decompose titanium borohydride, and the self-propagating reaction in the refiner mixed powder forms fine TiAl3 and TiB2 particles after high temperature extrusion into a filament refiner containing hydrogen pores, and then the filament refiner is cut into fine block refiners, and finally the fine block refiners are sprayed into the aluminum alloy melt by a high-pressure injection method, which plays a refining role after the melt solidifies, and the residual hydrogen element in the aluminum alloy melt is removed by vacuuming. The device has a simple structure, the prepared aluminum alloy has a good refinement effect, and the strength of the aluminum alloy casting is improved.

[0004] However, the above-disclosed aluminum alloy casting preparation device includes a punch assembly for pressing down the refiner mixed powder, a pulverizing wheel for cutting the filamentary intermediate alloy into refiner particles, and a high-pressure gas pipe for injecting high-pressure inert gas into the secondary pulverizing chamber in cooperation with a pressure pump. All three of the above need to be operated by separate electrical equipment, which increases energy consumption on the one hand, and on the other hand, the above design makes the structure of the equipment more complicated, resulting in difficulty in subsequent maintenance. Therefore, an aluminum alloy casting preparation device is proposed to improve the above problems. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing aluminum alloy casting preparation equipment needs to be driven by a variety of electrical equipment, has high energy consumption and complex structure.

[0006] In order to solve the above problems, the present invention provides an aluminum alloy casting preparation device, including a preparation furnace body:

[0007] A furnace cover is installed at the top of the preparation furnace body, and a plurality of equally spaced extrusion holes are arranged at the bottom of the preparation furnace body;

[0008] A feeding plate is arranged on the inner side of the preparation furnace body, and the peripheral side of the feeding plate is attached to the inner wall of the preparation furnace body;

[0009] A high-pressure gas pipe is rotatably penetrated at the center of the furnace cover, and the high-pressure gas pipe is rotatably connected to the furnace cover, the end of the high-pressure gas pipe located on the upper side of the furnace cover is connected to a high-pressure gas pump, and a first through hole for the high-pressure gas pipe to penetrate is provided at the center of the feed plate;

[0010] The bottom end of the high-pressure gas pipe rotates and penetrates the bottom end of the preparation furnace body, and a plurality of jet pipes are equidistantly arranged along the circumferential side of the bottom end of the high-pressure gas pipe, and the axes of the plurality of jet pipes are located on the same horizontal plane, the axes of the jet pipes do not intersect with the axis of the high-pressure gas pipe, and the inclination angles of the plurality of jet pipes relative to the high-pressure gas pipe are consistent;

[0012] A reset structure is arranged between the feeding plate and the furnace cover, and a heating structure is arranged on the inner side of the preparation furnace body.

[0013] In the above-mentioned aluminum alloy casting preparation equipment, by setting a feed plate and a high-pressure gas pipe that penetrates the preparation furnace body from top to bottom, in conjunction with the jet pipe at the bottom of the high-pressure gas pipe and the overflow hole on the side top surface, part of the high-pressure gas can enter the space between the feed plate and the top of the preparation furnace body from the overflow hole of the high-pressure gas pipe. Under the action of high gas pressure, the feed plate squeezes the refiner mixed powder downward, so that the refiner mixed powder is extruded through the extrusion hole at the bottom of the preparation furnace body to form a filamentary refiner; another part of the high-pressure gas is obliquely ejected from the jet pipe at the bottom of the high-pressure gas pipe, and the fine powder is extruded through the extrusion hole at the bottom of the preparation furnace body. The ejection of high-pressure gas cuts off the filamentary refiner, and since the high-pressure gas is ejected obliquely from the jet pipe at the bottom of the high-pressure gas pipe, the high-pressure gas pipe rotates under the reaction force of the oblique ejection of the high-pressure gas, thereby rotating the jet pipe while ejecting air, and cutting the filamentary refiner extruded from the extrusion hole at the bottom of the preparation furnace body into particles of uniform size. The design of this scheme only needs to use the existing high-pressure air pump, without the help of other electrical equipment, and has a simpler structure and is convenient for maintenance. Compared with the existing aluminum alloy casting preparation equipment, it greatly reduces the operating energy consumption.

[0014] As a further supplement to the present application, a spray cover is installed at the bottom end of the preparation furnace body, the bottom end of the spray cover is flat, and the bottom end of the spray cover is provided with a plurality of equidistantly distributed spray holes; the spray cover and the setting of the spray holes can make the granular refiner spray downward from the spray holes along with the high-pressure gas, and be evenly sprayed into the melting crucible containing the aluminum alloy melt, which has a better refinement effect after the melt solidifies, and the residual hydrogen element in the aluminum alloy melt is removed by vacuuming, so that the prepared aluminum alloy has a better refinement effect, further improving the strength of the aluminum alloy casting.

[0015] As a further supplement to the present application, a plurality of guide plates are fixedly connected to the inner wall of the high-pressure air pipe, and the plurality of guide plates are all arranged along the length direction of the high-pressure air pipe. The plurality of guide plates are all arranged at an angle, and the inclination angles of the plurality of guide plates are the same. The arrangement of the plurality of guide plates can utilize the effect of the passing high-pressure gas and the inclined guide plates to further enhance the rotation effect on the high-pressure air pipe on the basis of the inclined jet pipe.

[0016] As a further supplement to the present application, the guide plate is made of a heat-conducting material, and the high-pressure gas pipe is also made of a heat-conducting material; the guide plate increases the contact area with the high-pressure gas, thereby improving the heating effect on the high-pressure gas, so that the high-pressure gas carries a certain amount of heat, reducing the impact on the temperature of the refiner when in contact with the filamentary refiner.

[0017] As a further supplement to the present application, the heating structure includes a heating ring, which is coaxially arranged with the high-pressure gas pipe;

[0018] A plurality of heat-conducting columns are equidistantly and vertically fixed at the lower end of the heating ring, a second through hole for the heat-conducting columns to pass through is provided on the feeding plate, and the bottom end of the heat-conducting column extends to the inner bottom end of the preparation furnace body; the plurality of heat-conducting columns evenly distributed on the inner side of the preparation furnace body can cooperate with the heating ring to uniformly heat the refiner powder, and the plurality of heat-conducting columns cooperate with the heating ring to increase the contact area with the refiner powder, thereby achieving a better heating effect and effectively accelerating the heating speed.

[0019] As a further supplement to the present application, the jet pipe is arranged in contact with the bottom surface of the outer wall of the preparation furnace body, and the multiple extrusion holes are located on the side of the jet pipe away from the high-pressure gas pipe; so that the high-pressure gas ejected through the jet pipe can cooperate with the bottom surface of the outer wall of the preparation furnace body to better cut the filamentary refining agent.

[0020] As a further supplement to the present application, the reset structure includes a connecting rod, an elastic reset member and a fixing block;

[0021] The connecting rod is vertically fixed to the upper end of the feeding plate, the top end of the connecting rod slides through the furnace cover and is fixed to the fixed block, and the elastic reset part is fixed between the fixed block and the furnace cover; when the feeding plate reaches the bottom end of the preparation furnace body, the introduction of high-pressure gas is stopped, and the feeding plate moves upward and resets under the action of the elastic reset part.

[0022] As a further supplement to the present application, a protective tube is vertically fixed to the top of the furnace cover, the protective tube is located on the outside of the connecting rod, and the peripheral side of the fixed block slides in contact with the inner tube wall of the protective tube; the arranged protective tube can effectively prevent the connecting rod from being blocked by the outside and unable to move up smoothly.

[0023] As a further supplement to the present application, the protective tube is a transparent tube, and the peripheral surface of the fixed block is coated with a warning layer; the transparent protective tube and the warning layer on the surface of the fixed block make it convenient for the staff to observe the position of the fixed block, thereby judging the position of the feed plate in the preparation furnace body, and then judging the remaining amount of the refiner powder inside the preparation furnace body.

[0024] In summary, the present invention has the following beneficial effects:

[0025] By setting the feed plate and the high-pressure gas pipe that runs through the preparation furnace body from top to bottom, in conjunction with the jet pipe at the bottom of the high-pressure gas pipe and the overflow hole on the side top surface, part of the high-pressure gas can enter the space between the feed plate and the top of the preparation furnace body from the overflow hole of the high-pressure gas pipe. The feed plate squeezes the mixed powder of the refiner downward under the action of the high pressure, so that the mixed powder of the refiner is extruded through the extrusion hole at the bottom of the preparation furnace body to form a filamentary refiner; another part of the high-pressure gas is obliquely ejected from the jet pipe at the bottom of the high-pressure gas pipe, and the filamentary refiner is cut off by the ejection action of the high-pressure gas. Since the high-pressure gas is obliquely ejected from the jet pipe at the bottom of the high-pressure gas pipe, the high-pressure gas pipe rotates under the reaction force of the oblique ejection of the high-pressure gas, thereby rotating with the jet pipe while ejecting, and the filamentary refiner extruded from the extrusion hole at the bottom of the preparation furnace body is cut into particles of uniform size. The design of this scheme only needs to use the existing high-pressure gas pump, without the help of other electrical equipment, and the structure is simpler and convenient for maintenance. Compared with the existing aluminum alloy casting preparation equipment, the operation energy consumption is greatly reduced;

[0026] In addition, the spray cover cooperates with the spray hole to allow the granular refiner to be sprayed downward from the spray hole along with the high-pressure gas, and evenly sprayed into the melting crucible containing the aluminum alloy melt, thereby playing a better refinement role after the melt solidifies; the multiple guide plates can utilize the passing high-pressure gas and the inclined guide plates to further enhance the swirling effect on the high-pressure gas pipe on the basis of the inclined jet pipe; at the same time, the guide plates increase the contact area with the high-pressure gas, thereby improving the heating effect on the high-pressure gas, so that the high-pressure gas carries a certain amount of heat, reducing the influence on the temperature of the refiner when in contact with the filamentary refiner.

The bottom end of the high-pressure gas pipe 5 rotates and penetrates the bottom end of the preparation furnace body 1, and the bottom end of the high-pressure gas pipe 5 is equidistantly provided with a plurality of jet pipes 501 along its circumferential side, and the axes of the plurality of jet pipes 501 are located on the same horizontal plane, such as Figure 7 As shown, the axis of the jet pipe 501 does not intersect with the axis of the high-pressure gas pipe 5, and the inclination angles of the multiple jet pipes 501 relative to the high-pressure gas pipe 5 are all consistent, and an overflow hole 502 is provided on the side of the high-pressure gas pipe 5 near the top of the preparation furnace body 1, and a feed port 3 is provided at the top of the side of the preparation furnace body 1, and a sealing cover for sealing the feed port 3 is provided at the feed port 3.

[0041] like Fig. 9 As shown, by setting the feed plate 4 and the high-pressure gas pipe 5 that penetrates the preparation furnace body 1 from top to bottom, in conjunction with the jet pipe 501 at the bottom of the high-pressure gas pipe 5 and the overflow hole 502 on the side top surface, part of the high-pressure gas can enter the space between the feed plate 4 and the top of the preparation furnace body 1 from the overflow hole 502 of the high-pressure gas pipe 5. The feed plate 4 squeezes the refiner mixed powder downward under the action of high gas pressure, so that the refiner mixed powder is squeezed out through the extrusion hole 101 at the bottom of the preparation furnace body 1 to form a filamentary refiner; another part of the high-pressure gas is obliquely ejected from the jet pipe 501 at the bottom of the high-pressure gas pipe 5, which is used to The filamentary refining agent is cut off by the ejection effect of high-pressure gas, and since the high-pressure gas is ejected obliquely from the jet pipe 501 at the bottom of the high-pressure gas pipe 5, the high-pressure gas pipe 5 rotates under the reaction force of the oblique ejection of the high-pressure gas, thereby causing the jet pipe 501 to rotate while ejecting gas, and the filamentary refining agent extruded from the extrusion hole 101 at the bottom of the preparation furnace body 1 is cut into particles of uniform size. The design of this solution only needs to use the existing high-pressure air pump, without the help of other electrical equipment, and the structure is simpler and convenient for maintenance. Compared with the existing aluminum alloy casting preparation equipment, the operating energy consumption is greatly reduced.

[0042] As a further supplement to the present application, a spray cover 9 is installed at the bottom of the preparation furnace body 1, the bottom of the spray cover 9 is a flat surface, and a plurality of spray holes 901 are arranged at an equal distance from each other at the bottom of the spray cover 9; Fig. 9 As shown, the spray cover 9 cooperates with the setting of the spray hole 901 so that the granular refiner can be sprayed downward from the spray hole 901 along with the high-pressure gas, and evenly sprayed into the melting crucible (not shown in the figure) containing the aluminum alloy melt, which has a better refinement effect after the melt solidifies. The residual hydrogen element in the aluminum alloy melt is removed according to the existing conventional methods such as vacuuming, and the prepared aluminum alloy has a better refinement effect, which further improves the strength of the aluminum alloy casting.

[0043] like Figure 6 and Figure 8 It is shown that a plurality of guide plates 503 are fixedly connected to the inner wall of the high-pressure air pipe 5, and the plurality of guide plates 503 are all arranged along the length direction of the high-pressure air pipe 5, and the plurality of guide plates 503 are all inclined, and the inclination angles of the plurality of guide plates 503 are the same, the guide plates 503 are made of heat-conducting material, and the high-pressure air pipe 5 is also made of heat-conducting material; the arrangement of the plurality of guide plates 503 can utilize the effect of the passing high-pressure gas and the inclined guide plates 503, and further enhance the swirling effect on the high-pressure air pipe 5 on the basis of the inclined jet pipe 501; at the same time, the arranged guide plates 503 increase the contact area with the high-pressure gas, thereby improving the heating effect on the high-pressure gas, so that the high-pressure gas carries a certain amount of heat, and reduces the influence on the temperature of the refining agent when in contact with the filamentary refining agent.

[0044] It should be further explained that the portion of the high-pressure gas pipe 5 located outside the preparation furnace body 1 is made of non-heat-conducting material to reduce heat loss.

[0045] A heating structure is provided on the inner side of the preparation furnace body 1. Specifically, the heating structure includes a heating ring 6. The heating ring 6 is coaxially arranged with the high-pressure gas pipe 5. A plurality of heat-conducting columns 7 are equidistantly and vertically fixed to the lower end of the heating ring 6. A second through hole 402 for the heat-conducting column 7 to pass through is provided on the feeding plate 4. The bottom end of the heat-conducting column 7 extends to the inner bottom end of the preparation furnace body 1. The plurality of heat-conducting columns 7 evenly distributed on the inner side of the preparation furnace body 1 can cooperate with the heating ring 6 to evenly heat the refiner powder, and the plurality of heat-conducting columns 7 cooperate with the heating ring 6 to increase the contact area with the refiner powder, thereby achieving a better heating effect and effectively accelerating the heating speed.

[0046] Among them, the jet pipe 501 is arranged in contact with the bottom surface of the outer wall of the preparation furnace body 1, and the multiple extrusion holes 101 are all located on the side of the jet pipe 501 away from the high-pressure gas pipe 5; so that the high-pressure gas ejected through the jet pipe 501 can cooperate with the bottom surface of the outer wall of the preparation furnace body 1 to better cut the filamentary refining agent.

[0047] A reset structure is provided between the feeding plate 4 and the furnace cover 2. Specifically, the reset structure includes a connecting rod 10, an elastic reset member 11 and a fixed block 12, wherein the elastic reset member 11 is preferably a compression spring, the connecting rod 10 is vertically fixed to the upper end of the feeding plate 4, the top end of the connecting rod 10 slides through the furnace cover 2 and is fixed to the fixed block 12, and the elastic reset member 11 is fixed between the fixed block 12 and the furnace cover 2; when the feeding plate 4 reaches the bottom end of the preparation furnace body 1, the introduction of high-pressure gas is stopped, and at this time the feeding plate 4 moves upward and resets under the action of the elastic reset member 11.

[0048] In order to prevent the connecting rod 10 from being blocked by external forces and being unable to move upward smoothly, a protective tube 8 is vertically fixed to the top of the furnace cover 2. The protective tube 8 is located on the outside of the connecting rod 10, and the peripheral side of the fixing block 12 slides in contact with the inner tube wall of the protective tube 8.

[0049] Among them, the protective tube 8 is a transparent tube, and the surrounding side surface of the fixed block 12 is coated with a warning layer; the transparent protective tube 8 and the warning layer on the surface of the fixed block 12 make it convenient for the staff to observe the position of the fixed block 12, so as to judge the position of the feeding plate 4 in the preparation furnace body 1, and then judge the remaining amount of the refining agent powder inside the preparation furnace body 1.

[0050] In summary, compared with the prior art, in this solution, by providing the feed plate 4 and the high-pressure gas pipe 5 that penetrates the preparation furnace body 1 from top to bottom, in conjunction with the jet pipe 501 at the bottom of the high-pressure gas pipe 5 and the overflow hole 502 on the side top surface, part of the high-pressure gas can enter the space between the feed plate 4 and the top of the preparation furnace body 1 from the overflow hole 502 of the high-pressure gas pipe 5, and the feed plate 4 squeezes the refiner mixed powder downward under the action of the high gas pressure, so that the refiner mixed powder is squeezed out through the extrusion hole 101 at the bottom of the preparation furnace body 1 to form a filamentary refiner; another part of the high-pressure gas is discharged from the jet pipe 501 at the bottom of the high-pressure gas pipe 5 1 is sprayed obliquely, and the filamentary refiner is cut off by the spraying effect of high-pressure gas. Since the high-pressure gas is sprayed obliquely from the jet pipe 501 at the bottom of the high-pressure gas pipe 5, the high-pressure gas pipe 5 rotates under the reaction force of the oblique spraying of the high-pressure gas, so that the jet pipe 501 rotates while spraying, and the filamentary refiner extruded from the extrusion hole 101 at the bottom of the preparation furnace body 1 is cut into particles of uniform size. The design of this scheme only needs to use the existing high-pressure air pump, without the help of other electrical equipment, and the structure is simpler and convenient for maintenance. Compared with the existing aluminum alloy casting preparation equipment, the operation energy consumption is greatly reduced;

[0051] Compared with the prior art, in this solution, the spray cover 9 cooperates with the spray hole 901 to allow the granular refiner to be sprayed downward from the spray hole 901 along with the high-pressure gas, and evenly sprayed into the smelting crucible containing the aluminum alloy melt, so as to play a better refinement role after the melt solidifies; the multiple guide plates 503 can utilize the high-pressure gas passing through and the inclined guide plates 503 to further enhance the swirling effect on the high-pressure gas pipe 5 on the basis of the inclined jet pipe 501; at the same time, the guide plates 503 increase the contact area with the high-pressure gas, thereby improving the heating effect on the high-pressure gas, so that the high-pressure gas carries a certain amount of heat, and reduces the influence on the temperature of the refiner when in contact with the filamentary refiner;

[0052] Compared with the prior art, in the present solution, a plurality of heat-conducting columns 7 evenly distributed on the inner side of the preparation furnace body 1 can cooperate with the heating ring 6 to evenly heat the refiner powder, and the plurality of heat-conducting columns 7 cooperate with the heating ring 6 to increase the contact area with the refiner powder, so that the heating effect is better and the heating speed is effectively accelerated; the provided protective tube 8 can prevent the connecting rod 10 from being blocked by the outside and unable to move up smoothly, and the transparent protective tube 8 cooperates with the warning layer on the surface of the fixed block 12 to facilitate the staff to observe the position of the fixed block 12, thereby judging the position of the feeding plate 4 in the preparation furnace body 1, and then judging the remaining amount of the refiner powder inside the preparation furnace body 1.

[0053] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection.
