Description

Technical Field

[0002] Titanium alloy is a high-performance metal material based on titanium by adding alloying components such as aluminum and vanadium. It has become a core material in the fields of aerospace, biomedicine, etc. due to its low density, high specific strength and excellent corrosion resistance. However, the high activity of titanium makes it easy to react with gases such as oxygen and nitrogen to form brittle oxides during the smelting process. At the same time, melt inclusions will significantly reduce the ductility and fatigue life of the material. In order to break through the purity bottleneck, a titanium alloy secondary smelting device with an impurity isolation mechanism came into being. It is a high-efficiency purification equipment that works together through vacuum environment control, dynamic separation technology and a multi-stage filtration system.

[0003] In the existing equipment, the titanium alloy that has completed the initial smelting needs to flow into the secondary smelting furnace through the connecting pipe for secondary refining. During the process, the filter plate arranged in the pipe can intercept the metal inclusions in the melt to preliminarily reduce the impurity content. The metal inclusions accumulated in the filter plate need to be cleaned by reverse blowing with high-pressure pulse airflow after the device is shut down.

The driving gear 81 is meshed with the gear ring 57, and the rotating disk 51 is driven to rotate by gear transmission, thereby ensuring the accuracy and stability of the flow switching assembly 5 and improving the degree of automation of the device. As an embodiment of the present invention, the flip assembly 7 includes a fixing seat 71 installed on the inner wall of the first connecting tube 2, an elastic telescopic rod 72 is installed on the outer wall of the fixing seat 71, and fan gears 73 are installed on the upper and lower sides of the end of the elastic telescopic rod 72, and the fan gear 73 is meshed with the rotating gear 56. The fixing seat 71 provides a stable installation foundation for the elastic telescopic rod 72 and the fan gear 73 to prevent the elastic telescopic rod 72 and the fan gear 73 from being displaced or shaken, thereby ensuring the accuracy and reliability of the transmission. The elastic telescopic rod 72 can perform telescopic movement, which can change the relative position of the fan gear 73 and the rotating gear 56, ensuring that the two can be accurately meshed, ensuring the smoothness of the transmission, and the meshing of the fan gear 73 with the rotating gear 56 can accurately control the rotation angle and speed of the baffle 54, ensuring that a closed space is created for the filter plate 6 at an appropriate time, thereby improving the effect and accuracy of impurity cleaning; As an embodiment of the present invention, the diameter of the baffle 54 is larger than the diameter of the flow opening 52, and a filter plate 6 is fixedly installed on the inner wall of each group of flow openings 52. The baffle 54 can completely cover the flow opening 52, and a relatively closed space is constructed for the filter plate 6 where metal inclusions are accumulated, which is conducive to the centralized cleaning work and prevents metal inclusions from re-entering the melt and affecting product quality. As an embodiment of the present invention, the swing feeding assembly 11 includes a moving groove 111 opened at the top of the transmission rod 102, and a rotating rod 112 is installed on the inner wall of the moving groove 111, and a rotating protrusion 113 is fixed on the outer wall of the rotating rod 112. An arc groove 114 for the rotating protrusion 113 to move is opened on the inner wall of the moving groove 111, and a transmission gear 115 is sleeved on the end of the rotating rod 112. When the rotating rod 112 rotates, the rotating protrusion 113 and the arc groove 114 cooperate with each other, effectively converting the simple linear motion of the transmission rod 102 into a complex swinging and feeding motion, accurately controlling the swing angle and feeding distance of the rotating rod 112, so that the annular arc brush 12 can clean the surface of the filter plate 6 more comprehensively, thereby improving the cleaning quality and effect; As an embodiment of the present invention, the transmission gear 115 is meshed with the mobile rack 105, and the linear motion of the mobile rack 105 is converted into the rotational motion of the rotating rod 112, so as to provide power for the circular arc brush 12, and realize the cleaning action on the surface of the filter plate 6, and the width of the mobile rack 105 is greater than the moving distance of the transmission gear 115, so as to ensure that when the transmission gear 115 moves, it can always maintain a meshing state with the mobile rack 105, so as to ensure the continuity of the transmission; As an embodiment of the present invention, a plurality of groups of extrusion blocks 106 are installed at equal intervals on the inner wall of the cleaning seat 9, and the lower side of the end of the extrusion block 106 close to the sliding block 103 is inclined, and the end of the extrusion block 106 protrudes from the inner wall of the cleaning seat 9, and the second spring 107 is stronger than the first spring 104. When the transmission rod 102 drives the sliding block 103 to move upward, the sliding block 103 will contact the extrusion blocks 106 distributed at equal intervals on the inner wall of the cleaning seat 9 in turn. Since the extrusion force of the second spring 107 is greater than the first spring 104, the sliding block 103 will be squeezed and slide downward. When the sliding block 103 moves to the set stroke, the extrusion block 106 is squeezed to the inner wall of the cleaning seat 9 through the oblique angle design of the end of the extrusion block 106. When the sliding block 103 passes over the extrusion block 106, it resumes the upward movement trend under the action of the spring force, and this is repeated to achieve the reciprocating motion of the sliding block 103. As an embodiment of the present invention, when the electric push rod 101 is at the bottom position, the end of the annular arc brush 12 is located on the inner wall of the first cleaning port 41, which ensures that the cleaning work can be carried out quickly and effectively, and ensures that the annular arc brush 12 does not affect the movement of the rotating disk 51; Working principle: When using the titanium alloy secondary smelting device with an impurity isolation mechanism, the titanium alloy that has been initially smelted will first flow into the sliding sleeve 4 through the second connecting pipe 3, pass through the first cleaning port 41 opened on the outer wall of the sliding sleeve 4, and be filtered through the filter plate 6 installed on the inner wall of the first cleaning port 41, and enter the secondary smelting furnace 1 through the first connecting pipe 2 for secondary refining. As the work continues to advance, the metal inclusions on the outer wall of the filter plate 6 in the first cleaning port 41 gradually accumulate, causing blockage. At this time, the rotating disk 51 and the sliding sleeve 4 will slide toward the direction of the first connecting pipe 2 under the impetus of the melt flow resistance, thereby improving the degree of automation and efficiency of production. When the pressure sensor 82 of the driving gear 81 installed on the inner wall of the sliding sleeve 4 contacts the end of the first connecting pipe 2 as the sliding sleeve 4 moves, the pressure sensor 82 is The sensor 82 cooperates with the background control to activate the motor to drive the driving gear 81 to rotate. Since the driving gear 81 is meshed with the gear ring 57, the rotating disk 51 is driven to rotate accordingly. While the rotating disk 51 rotates, the connecting rod 55 installed on its inner wall also rotates synchronously. Because the rotating gear 56 installed at the end of the connecting rod 55 is meshed with the fan gear 73, and the fan gear 73 is fixedly installed at the end of the elastic telescopic rod 72, when the rotating disk 51 rotates to the second cleaning port 53 and coincides with the first cleaning port 41 opened on the outer wall of the sliding sleeve 4, the baffle 54 will rotate 180°, opening the spare filter plate 6 channel while creating a closed space for the filter plate 6 with accumulated metal inclusions, which is conducive to subsequent cleaning work and ensures the continuity of the melt flow, avoids interference with the melt flow during the cleaning process, and improves the working efficiency; When the rotating disk 51 rotates to the point where the second cleaning opening 53 coincides with the first cleaning opening 41 opened on the outer wall of the sliding sleeve 4, the electric push rod 101 begins to push the transmission rod 102 upward, and the sliding block 103 installed on the outer wall of the transmission rod 102 slides upward synchronously. As the transmission rod 102 continues to move, the outer wall of the sliding block 103 gradually squeezes the squeezing block 106. Since the squeezing force of the second spring 107 is greater than the first spring 104, the sliding block 103 will be squeezed to slide downward. When the sliding block 103 moves to a limited stroke, through the bevel design of the end of the squeezing block 106, the sliding block 103 squeezes the squeezing block 106 to the inner wall of the cleaning seat 9. After the sliding block 103 passes over the squeezing block 106, it resumes its upward movement trend under the action of the spring force of the second spring 107. Since multiple groups of squeezing blocks 106 are installed at equal intervals on the inner wall of the cleaning seat 9, the upward movement of the sliding block 103 is realized. The movable rack 105 installed on the outer wall of the sliding block 103 is meshed with the transmission gear 115, so that the rotating rod 112 swings back and forth, and the rotating protrusion 113 installed on the outer wall of the rotating rod 112 is located in the arc groove 114. With the reciprocating swing of the rotating rod 112, the rotating protrusion 113 will push the rotating rod 112 to perform reciprocating linear motion, so that the annular arc brush 12 installed at the end of the rotating rod 112 can cover the surface of the filter plate 6 for composite cleaning, and clean the surface of the filter plate 6 from multiple angles and directions, thereby increasing the cleaning efficiency of metal inclusions, improving the cleaning effect, and ensuring that the filter plate 6 can be put into efficient use again in the future, further enhancing the stability and reliability of the entire filtering system.
