Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, and in particular relates to a reaction vessel for producing copper-titanium etching solution. Background Technology

[0002] Copper-titanium etching solution is a chemical used to etch copper-titanium alloys or copper-titanium composites. It has important applications in semiconductor manufacturing, microelectronic packaging, and other precision engineering fields. In the production of copper-titanium etching solution, operators may need to add several sets of raw materials to a reaction vessel. Using the reaction vessel as a carrier, these raw materials react to obtain the copper-titanium etching solution. Therefore, it can be seen that existing reaction vessels basically meet the needs of users, but the following problems still exist.

[0003] When using a reaction vessel, the operator adds raw materials to the vessel through pipes, allowing the materials to react. To improve the reaction rate and uniformity within the vessel, a stirring device may be installed to agitate the raw materials, thereby improving the reaction rate and uniformity. However, if the stirring device in the reaction vessel is relatively simple, it may be impossible to agitate the raw materials uniformly. Therefore, we propose a reaction vessel for the production of copper-titanium etching solution. Utility Model Content

[0004] This invention provides a reaction vessel for producing copper-titanium etching solution, which improves the stirring efficiency and reaction uniformity by increasing the stirring method.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reaction vessel for producing copper-titanium etching solution, comprising a reaction vessel body and a stirring rod, wherein the stirring rod is installed at the end of the reaction vessel body, and a fixing cavity fixed to the inner wall of the reaction vessel body is sleeved on the surface of the stirring rod, and a transmission component is provided inside the fixing cavity, wherein a rotating rod is fixed at the end of the transmission component, and a plurality of stirring blades are fixed on the surface of the rotating rod, and a flow-guiding cavity is sleeved on the surface of the stirring blades and disposed in the reaction vessel body, and the outer wall of the flow-guiding cavity is connected to the inner wall of the reaction vessel body through a fixing frame.

[0006] Furthermore, a fourth gear is fixed on the surface of the stirring rod and disposed in the fixed cavity, and rotating components are meshed around the fourth gear. A first gear is meshed on the other end of each rotating component, and a rotating rod is fixed in the middle of each first gear.

[0007] Furthermore, the rotating component includes a second gear, a rotating shaft, and a third gear. The second gear and the third gear are fixed to the two ends of the rotating shaft, respectively. One side of the third gear meshes with a fourth gear, and one side of the second gear meshes with a first gear.

[0008] Furthermore, each of the rotating shaft surfaces is fitted with a rotating sleeve, and a mounting bracket is fixed to the outer wall of the rotating sleeve, and the mounting bracket is fixed to the inner wall of the fixing cavity.

[0009] Furthermore, the stirring rod and the rotating rod are respectively fitted with a second extension sleeve and a first extension sleeve at one end of the fixed cavity, and both the second extension sleeve and the first extension sleeve are fixed on the fixed cavity.

[0010] Furthermore, both the upper and lower ends of the rotating rod are provided with clearance grooves, and the surfaces of the clearance grooves are fitted with traction sleeves. The outer walls of the traction sleeves are connected to the inner walls of the drainage cavity through support frames.

[0011] The beneficial effects of this utility model are:

[0012] 1. The reaction vessel for producing copper-titanium etching solution is equipped with a rotating rod, stirring blades, and a drainage chamber. The rotating rod drives the stirring blades to rotate in the drainage chamber, causing the stirring blades to draw the liquid into the drainage chamber and discharge it through the drainage chamber, thereby dispersing the raw materials in the main body of the reaction vessel, thus improving the stirring efficiency and reaction uniformity.

[0013] 2. The reactor for producing copper-titanium etching solution is equipped with a clearance groove, a traction sleeve, and a support frame. The traction sleeve is fitted inside the clearance groove, and the two sides of the support frame are fixed between the surface of the traction sleeve and the inner wall of the drainage cavity, respectively. This allows the support frame to support the rotating rod through the traction sleeve, increasing the stability of the rotating rod as it rotates within the drainage cavity.

[0020] To further understand the utility model's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] Example:

[0022] Please see Figure 1 - Figure 4 A reaction vessel for producing copper-titanium etching solution includes a reaction vessel body 1 and a stirring rod 2. The stirring rod 2 is installed at the end of the reaction vessel body 1. A fixed cavity 3 welded to the inner wall of the reaction vessel body 1 is sleeved on the surface of the stirring rod 2. A transmission component is provided inside the fixed cavity 3. A rotating rod 6 is welded to the end of the transmission component. Several sets of stirring blades 7 are welded to the surface of the rotating rod 6. A flow-guiding cavity 4 is provided inside the reaction vessel body 1 on the surface of the stirring blades 7. The outer wall of the flow-guiding cavity 4 is connected to the inner wall of the reaction vessel body 1 through a fixing frame 5. A fourth gear 16 is welded to the surface of the stirring rod 2 and is provided inside the fixed cavity 3. Rotating components 17 mesh around the fourth gear 16. The rotating components 17 include a second gear 13, a rotating shaft 14, and a third gear 15. The second gear 13 and the third gear 15 are welded to the two ends of the rotating shaft 14, respectively. One side of the third gear 15 is connected to the fourth gear 16. The second gear 13 meshes with the first gear 12 on one side, and the other end of the rotating component 17 also meshes with the first gear 12. A rotating rod 6 is welded to the middle of each first gear 12. After the operator adds the raw material into the reactor body 1, the operator starts the motor, causing the motor to drive the stirring rod 2 to rotate. The stirring rod 2 stirs the raw material in the reactor body 1. During the rotation of the stirring rod 2, the stirring rod 2 drives the fourth gear 16 to rotate. Since the fourth gear 16 meshes with the third gear 15, the fourth gear 16 drives the third gear 15 to rotate. When the third gear 15 rotates, it drives the second gear 13 to rotate via the rotating shaft 14. Gear 13 meshes with the first gear 12, causing the first gear 12 to drive the rotating rod 6 to rotate. The rotating rod 6 drives the stirring blade 7 to rotate, causing the stirring blade 7 to rotate within the inlet cavity 4. When the stirring blade 7 rotates within the inlet cavity 4, it draws the liquid from the reactor body 1 into the inlet cavity 4. The liquid moves upward as the stirring blade 7 rotates. When the liquid reaches the opening of the inlet cavity 4, it moves out from the opening and re-enters the mixed liquid. Thus, when the stirring rod 2 is stirring the raw materials, the stirring blade 7 draws the liquid into the inlet cavity 4 and discharges the liquid through the inlet cavity 4, facilitating further stirring of the liquid, thereby improving the uniformity of liquid stirring and increasing the stirring rate.

[0023] In other embodiments, a rotating sleeve 8 is fitted on the surface of the rotating shaft 14, and a mounting bracket 9 is welded to the outer wall of the rotating sleeve 8. The mounting bracket 9 is welded to the inner wall of the fixed cavity 3. The rotating sleeve 8 is fitted on the surface of the rotating shaft 14, and the two ends of the mounting bracket 9 are respectively fixed between the surface of the rotating sleeve 8 and the inner wall of the fixed cavity 3, so that the mounting bracket 9 supports the rotating shaft 14 through the rotating sleeve 8, and supports the rotating shaft 14 in the fixed cavity 3. The stability of the rotation of the rotating shaft 14 is increased by supporting the rotating shaft 14 through the mounting bracket 9 and the rotating sleeve 8.

[0024] In other embodiments, a second extension sleeve 11 and a first extension sleeve 10 are respectively fitted onto the end of the stirring rod 2 and the rotating rod 6 that penetrate the fixed cavity 3, and both the second extension sleeve 11 and the first extension sleeve 10 are fixed on the fixed cavity 3. The second extension sleeve 11 and the first extension sleeve 10 are respectively fitted onto the end of the stirring rod 2 and the rotating rod 6 that penetrate the fixed cavity 3, so that the first extension sleeve 10 and the second extension sleeve 11 increase the contact area of ​​the rotating rod 6 and the stirring rod 2 that penetrate the fixed cavity 3, thereby improving the stability of the rotating rod 6 and the stirring rod 2 during rotation.

[0025] In other embodiments, clearance grooves 19 are provided at both the upper and lower ends of the rotating rod 6, and traction sleeves 18 are fitted on the surface of the clearance grooves 19. The outer walls of the traction sleeves 18 are connected to the inner wall of the drainage cavity 4 through the support frame 20. When the rotating rod 6 rotates, the rotating rod 6 drives the clearance grooves 19 to rotate on the surface of the traction sleeves 18. The two ends of the support frame 20 are respectively welded between the inner wall of the drainage cavity 4 and the surface of the traction sleeves 18, so that the support frame 20 and the traction sleeves 18 support the rotating rod 6 and improve the stability of the rotating rod 6.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
