Description

Technical Field

[0001] The present invention relates to the field of mixing and stirring equipment, in particular to a stirring device for preparing ultrafine alloy powder based on a chemical coprecipitation process. Background Art

[0002] In the key step of preparing ultrafine alloy powders by chemical coprecipitation, efficient and uniform mixing of the metal ion solution and the precipitant directly determines the quality of the final product. However, the conventional stirring devices currently used have obvious shortcomings in solution circulation and mixing. Their stirring method often only achieves mixing in the central local area, and the circulation of the solution in the upper and lower parts of the barrel is extremely slow. This makes it difficult for the metal ions and the precipitant to fully contact and react in a short time, greatly reducing the reaction rate and prolonging the preparation cycle. Conventional devices also perform poorly in treating the solution at the bottom of the barrel. The solution at the bottom side is prone to insufficient mixing due to insufficient disturbance. This uneven mixing leads to differences in the composition and particle size distribution of the alloy powder, seriously affecting the uniformity of product quality. In addition, the impact force of existing stirring devices on the solution is limited, and the mixing method is relatively simple. The solution lacks sufficient power and diversified action forms during the mixing process, which cannot effectively improve the mixing rate and cannot meet the needs of large-scale, high-efficiency production. Therefore, we propose a stirring device for preparing ultrafine alloy powders based on the chemical coprecipitation process to address the above-mentioned problems. Summary of the Invention

[0013] Preferably, a turbine is installed at the lower part of the outer periphery of the rotating shaft, the turbine is arranged at the lower part of the second sealing plate, and the turbine is arranged at the lower part of the inner side of the built-in cylinder.

[0014] Preferably, a rotating shaft is installed inside one end of the catheter away from the built-in tube through the second fixing frame, and the rotating shaft is rotatably connected to the second fixing frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] When the rotating shaft of the present invention rotates, the reciprocating threaded section drives the second sealing plate to rise and fall.

The impeller can drive the rotating shaft to rotate synchronously, thereby driving the spoiler disk and spoiler blades at the end of the rotating shaft to rotate. The spoiler disk and spoiler blades can disturb the solution at the bottom of the barrel to further enhance the mixing effect of the solution inside the barrel, thereby effectively improving the mixing efficiency of the metal ion solution and the precipitant.

[0020] When the solution enters the connecting pipe, it will be introduced into the mounting ring, and will further enter the rotating ring and be discharged through the impact head and tail flow port at the bottom. When the solution is discharged through the impact head, the continuously applied pressure will cause the discharged solution to form a "water column", which will impact and mix the surrounding solutions, thereby greatly increasing the mixing rate.

[0021] During use, part of the solution is discharged through the second opening at the end of the tail flow outlet. Under the guidance of the inclined end of the tail flow outlet, a propulsion force will be applied to the rotating ring, causing the rotating ring to rotate, thereby greatly increasing the impact range of the impact "water column", further improving the mixing effect of the solution inside the barrel, and avoiding the poor mixing effect of the solution on the bottom side of the barrel. The turbine can be driven to rotate synchronously through the rotating shaft, and the solution at the bottom of the built-in cylinder can be assisted in stirring by the turbine. At the same time, the connectivity between the inside and outside of the built-in cylinder can be improved, which is beneficial to actual use. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0032] like Figures 1-8The stirring device for preparing ultrafine alloy powder based on the chemical coprecipitation process shown includes a mixing barrel 1, which includes a barrel body 101. A circulation component and a bottom mixing component are arranged inside the barrel body 101.

[0033] The circulation component is used to circulate the solution and precipitant in the upper and lower parts of the barrel body 101.

[0034] The bottom mixing component is used to mix the solution and the precipitant on the bottom side of the barrel body 101.

[0035] The circulation component includes an internal cylinder 109, a rotating shaft 110 passes through the top of the internal cylinder 109, a reciprocating threaded section 127 is provided in the middle and lower part of the internal cylinder 109, and a threaded ring 133 is connected to the outer periphery of the reciprocating threaded section 127, and a sealing plate 129 is fixedly connected to the outer periphery of the top of the threaded ring 133, and a uniformly distributed bottom plate 130 is fixedly connected to the bottom of the sealing plate 129, and a uniformly distributed through-port 131 is opened on the outer side of the middle of the sealing plate 129. The upper and inner parts of the threaded ring 133 are all slidably connected to the slip ring 126, and the outer periphery of the top of the slip ring 126 is fixedly connected to the sealing plate 125, and the outer periphery of the middle of the sealing plate 125 is opened. 8. The first through-port 128 and the second through-port 131 are staggered. Both sides of the upper periphery of the built-in cylinder 109 are fixedly connected with symmetrical conduits 105. The end of the conduit 105 away from the built-in cylinder 109 passes through the side wall of the barrel body 101 and is connected back to the bottom of the barrel body 101. The end of the conduit 105 away from the built-in cylinder 109 is internally installed with a rotating shaft 119 through a fixing frame 2 120. The rotating shafts 119 are rotatably connected to the fixing frame 2 120. The middle part of the outer periphery of the rotating shaft 119 is fixedly connected with an impeller 121. The outer end of the rotating shaft 119 is fixedly connected with a spoiler 118, and both ends of the spoiler 118 are fixedly connected with spoiler blades 112.

[0036] Furthermore, in a specific implementation, the solution in the lower part of the barrel body 101 can be led out and re-injected by continuously lifting and lowering the sealing plate 125 and the sealing plate 2 129, so that the rapid circulation mixing of the upper and lower solutions in the barrel body 101 can be quickly achieved. In this process, the solution will flow back to the bottom of the barrel body 101 after passing through the conduit 105, thereby further achieving the impact on the bottom of the barrel body 101, and achieving sufficient circulation mixing of the metal ion solution and the precipitant. When the solution is circulated and mixed through the conduit 105, When the solution passes through and contacts the impeller 121, the impeller 121 will be driven to rotate accordingly. The impeller 121 can drive the rotating shaft 119 to rotate synchronously, thereby driving the spoiler disk 118 and the spoiler blades 112 at the end of the rotating shaft 119 to rotate. The spoiler disk 118 and the spoiler blades 112 can disturb the solution at the bottom of the barrel body 101 and further enhance the mixing effect of the solution inside the barrel body 101, thereby effectively enhancing the mixing efficiency of the metal ion solution and the precipitant.

[0037] Among them, an end cover 102 is installed on the top of the barrel body 101, and a fixing frame 107 is fixedly connected to the lower part of the outer periphery of the barrel body 101. A plurality of feed ports 104 are installed on one side of the top of the end cover 102. The rotating shaft 110 is rotatably connected to the built-in cylinder 109. The top of the rotating shaft 110 is fixedly connected to a servo motor 103, and the servo motor 103 is installed at the middle part of the top of the end cover 102. A discharge port 108 is installed on one side of the bottom of the barrel body 101, and a control panel 106 is installed at the lower part of one side of the outer periphery of the barrel body 101. The control panel 106 is electrically connected to the servo motor 103. A uniformly distributed opening 114 is opened at the lower part of the outer periphery of the built-in cylinder 109, and a plurality of connecting ports 111 are opened on the outside of the middle part of the top of the built-in cylinder 109. A one-way valve is installed inside the connecting port 111. A turbine 132 is installed at the lower part of the outer periphery of the rotating shaft 110. The turbine 132 is arranged at the lower part of the sealing plate 2 129, and the turbine 132 is arranged at the lower inner side of the built-in cylinder 109.

[0038] Furthermore, in a specific implementation, people can inject metal ion solution and precipitant into the mixing barrel 1 through the feed port 104. After the metal ion solution and precipitant are injected, people can start the servo motor 103 through the control panel 106. The servo motor 103 can drive the rotating shaft 110 to rotate. When the rotating shaft 110 rotates, the reciprocating thread section 127 drives the second sealing plate 129 to rise and fall. When the second sealing plate 129 is lowered, under the pressure of the solution, the first sealing plate 125 and the second sealing plate 129 will be driven to separate, so that the internal solution will continuously enter the inner upper part of the built-in cylinder 109 through the second through port 131 and the first through port 128. The solution inside the barrel body 101 can be flush with the solution inside the built-in cylinder 109. Then, when the second sealing plate 129 is driven to rise, the first sealing plate 125 will fall under the action of gravity and solution pressure, so that the first sealing plate 125 and the second sealing plate 129 overlap. After the overlap of the first sealing plate 125 and the second sealing plate 129, a closed piston will be formed. Through the lifting of the first sealing plate 125 and the second sealing plate 129, the solution in the upper part of the built-in cylinder 109 can be discharged from the built-in cylinder 109, and the discharged solution will be discharged through the conduit 105 and the connecting pipe 115. The connection between the interior of the built-in cylinder 109 and the barrel body 101 can be achieved through the opening 114 at the bottom of the built-in cylinder 109.

[0039] Among them, the bottom mixing assembly includes a mounting ring 113, which is arranged at the lower outer side of the built-in tube 109, and a plurality of connecting pipes 115 are fixedly connected to the top of the mounting ring 113. The tops of the connecting pipes 115 are fixedly connected to the upper outer periphery of the built-in tube 109, and the connecting pipes 115 are connected to the built-in tube 109 and the interior of the mounting ring 113. A swivel 122 is rotatably connected to the inner side of the bottom of the mounting ring 113, and a connecting ring 116 is fixedly connected to the bottom of the swivel 122. The mounting ring 113 is connected to the interior of the swivel 122. The inner and outer sides of the bottom of the connecting ring 116 are fixedly connected with evenly distributed impact heads 117, and the middle part of the bottom end of the connecting ring 116 is fixedly connected with evenly distributed tail ports 124. The ends of the tail ports 124 are provided with evenly distributed openings 123, and the ends of the tail ports 124 are all inclined.

[0040] Furthermore, in a specific implementation, after the solution enters the connecting tube 115, it will be introduced into the mounting ring 113, and will further enter the rotating ring 122 and be discharged through the impact head 117 and the tail flow port 124 at the bottom. When the solution is discharged through the impact head 117, the continuously applied pressure will cause the discharged solution to form a "water column", thereby impacting and mixing the surrounding solutions. At the same time, part of the solution is discharged through the opening 123 at the end of the tail flow port 124. Under the guidance of the inclined end of the tail flow port 124, the rotating ring 122 applies a propulsion force to make the rotating ring 122 rotate, thereby greatly increasing the impact range of the impact "water column", further improving the mixing effect of the solution inside the barrel body 101, and avoiding the poor mixing effect of the solution on the bottom side of the barrel body 101. In actual use, the rotating shaft 110 can drive the turbine 132 to rotate synchronously, and the turbine 132 can assist in stirring the solution at the bottom of the built-in cylinder 109, and at the same time can improve the connection effect between the inside and outside of the built-in cylinder 109, which is beneficial to actual use.

[0041] Working principle:

[0042] In actual use, people can inject metal ion solution and precipitant into the mixing barrel 1 through the feed port 104. When the metal ion solution and precipitant are injected, people can start the servo motor 103 through the control panel 106. The servo motor 103 can drive the rotating shaft 110 to rotate. When the rotating shaft 110 rotates, it will drive the sealing plate 2 129 to rise and fall through the reciprocating thread section 127. When the sealing plate 2 129 is lowered, under the pressure of the solution, the sealing plate 1 125 and the sealing plate 2 129 will be driven to separate, so that the internal solution will continuously enter the inner upper part of the built-in cylinder 109 through the through port 2 131 and the through port 1 128, so that the solution inside the barrel body 101 can be flush with the solution inside the built-in cylinder 109. Then, when the sealing plate 129 is lowered, the sealing plate 1 125 and the sealing plate 2 129 will be driven to separate, so that the internal solution will continuously enter the inner upper part of the built-in cylinder 109 through the through port 2 131 and the through port 1 128, so that the solution inside the barrel body 101 can be flush with the solution inside the built-in cylinder 109. When the second sealing plate 129 is driven to rise, under the action of gravity and solution pressure, the sealing plate 125 will fall, so that the sealing plate 125 and the sealing plate 2 129 overlap, and a closed piston will be formed after the sealing plate 125 and the sealing plate 2 129 overlap. The solution in the upper part of the built-in cylinder 109 can be discharged from the built-in cylinder 109 by the lifting of the sealing plate 125 and the sealing plate 2 129, and the discharged solution will be discharged through the conduit 105 and the connecting pipe 115. The connection between the interior of the built-in cylinder 109 and the barrel body 101 can be achieved through the opening 114 at the bottom of the built-in cylinder 109. The solution in the lower part of the barrel body 101 can be discharged and re-injected by the continuous lifting and lowering of the sealing plate 125 and the sealing plate 2 129, so that the upper and lower solutions in the barrel body 101 can be quickly achieved. Rapid circulation mixing. During this process, the solution will flow back to the bottom of the barrel body 101 after passing through the conduit 105, thereby further impacting the bottom of the barrel body 101 and achieving sufficient circulation mixing of the metal ion solution and the precipitant. When the solution is circulated and mixed through the conduit 105, the solution will pass through and contact the impeller 121, thereby driving the impeller 121 to follow the rotation, and the impeller 121 can drive the rotating shaft 119 to rotate synchronously, thereby driving the spoiler 118 and the spoiler blade 112 at the end of the rotating shaft 119 to rotate, and the spoiler disk 118 and the spoiler blade 112 can disturb the solution at the bottom of the barrel body 101 to further enhance the mixing effect of the solution inside the barrel body 101, thereby achieving The mixing efficiency of the metal ion solution and the precipitant is effectively improved. After the solution enters the connecting tube 115, it will be introduced into the mounting ring 113, and will further enter the rotating ring 122 and be discharged through the impact head 117 and the tail flow port 124 at the bottom. When the solution is discharged through the impact head 117, the continuously applied pressure will cause the discharged solution to form a "water column", thereby impacting and mixing the surrounding solutions. At the same time, part of the solution is discharged through the opening 123 at the end of the tail flow port 124. Under the guidance of the inclined end of the tail flow port 124, a propulsion force will be applied to the rotating ring 122, causing the rotating ring 122 to rotate, thereby greatly increasing the impact range of the impact "water column" and further improving the mixing effect of the solution inside the barrel body 101.To avoid poor mixing of the solution at the bottom side of the barrel 101, in actual use, the shaft 110 can drive the turbine 132 to rotate synchronously, and the turbine 132 can assist in stirring the solution at the bottom of the built-in cylinder 109, while improving the communication effect between the inside and outside of the built-in cylinder 109, which is beneficial to actual use.
