Description

Technical Field

[0001] This utility model relates to the field of electrochemical purification metallurgical technology, specifically a positioning ring device for a high-purity titanium collection tower. Background Technology

[0002] Currently, the core equipment for high-purity titanium production, the molten salt electrolysis furnace, is mainly divided into three parts: the electrolytic cell, the transition section, and the collection tower. The electrolytic cell and the transition section are fixed devices, while the collection tower is a device for collecting and transferring purified materials. After the purified high-purity titanium enters the collection tower through the lifting mechanism above it, the transition section's gate valve structure closes, isolating the electrolytic cell from the collection tower. Once the pressure inside the collection tower stabilizes, the flap valve mechanism below the collection tower closes, isolating the high-purity titanium inside from the air. At this point, by releasing the pressure in the transition section and the flap valve chamber, the collection tower can be transferred to a cooling position for natural cooling. After the required cooling time is reached, the internal material is transferred to the ground discharge position for further transfer. The empty electrodes are then resuspended on the electrode hangers inside the collection tower. The collection tower with the empty electrodes needs to be placed back above the electrolytic cell for a new round of electrolytic purification, thereby achieving full utilization of the electrolytic cell.

[0003] The existing traditional alignment of the collection tower and the transition section is done manually. At this time, the operator not only has to use the remote control to make the edge of the circular opening at the bottom of the collection tower coincide with the circular opening of the transition section, but also has to control the buckles and locks on the two devices to ensure precise alignment. The alignment is time-consuming and inaccurate. In addition, there is a risk of scraping the internal electrodes and purified materials. To address this, we propose a high-purity titanium collection tower positioning ring device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a positioning ring device for a high-purity titanium collection tower, thus solving the problems mentioned below.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning ring device for a high-purity titanium collection tower includes a pressure ring and guide sliders. Several guide sliders are provided, and all of the guide sliders are disposed on the outer periphery of the pressure ring and are evenly distributed along the circumference. The guide sliders have a constricted structure from top to bottom.

[0007] Furthermore, several of the guide sliders are connected to the pressure ring by welding or machining in one piece, and the gap between the guide sliders is used to accommodate the locking buckle of the transition section and align it with the buckle at the bottom of the collection tower.

[0008] Furthermore, the upper and lower surfaces of the pressure ring are respectively provided with sealing ring grooves, the diameter of the sealing ring groove on the upper surface is larger than the diameter of the sealing ring groove on the lower surface, and a sealing gasket is embedded in the sealing ring groove.

[0009] Furthermore, the screw hole is a blind hole that does not penetrate through, and a bolt is screwed into the internal thread of the blind hole. The pressure ring and the transition section are connected by the bolt and the blind hole to form an integral structure.

[0010] Furthermore, the guide slider has a chamfer to guide the lower edge of the collection tower to slide into the reserved position for precise alignment.

[0011] Beneficial effects

[0012] This invention provides a positioning ring device for a high-purity titanium collection tower. Compared with the prior art, it has the following advantages:

[0013] 1. This utility model utilizes a series of guide sliders evenly distributed from top to bottom in a constricted shape around the outer circumference of the pressure ring. This constricted structure guides the center of the bottom opening of the collection tower to automatically align with the center of the pressure ring as the collection tower descends and returns to its position, ensuring they are on the same vertical line. Simultaneously, the guide sliders have chamfered edges, allowing the lower edge of the collection tower to smoothly slide into its pre-set position and precisely align with the transition section lock. This eliminates the need for repeated manual adjustments, significantly reducing alignment time and solving the problems of time-consuming and inaccurate traditional manual alignment. It also avoids the risk of internal electrode and material scraping against the wall.

[0014] 2. This practical design features sealing ring grooves of different diameters on the upper and lower surfaces of the pressure ring (the upper surface diameter is larger than the lower surface), with embedded sealing gaskets forming a stepped sealing structure. The larger diameter groove on the upper surface facilitates the installation and positioning of the sealing gasket, while the smaller diameter groove on the lower surface allows for more even force distribution on the sealing gasket during bolt tightening, enhancing the sealing effect. This effectively prevents leakage of molten salt vapor and inert gas, avoids the entry of outside air affecting the purity of high-purity titanium, and prevents abnormal internal pressure from causing safety hazards, thereby improving the stability and reliability of equipment operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1, please refer to Figure 1 This utility model provides a technical solution: a positioning ring device for a high-purity titanium collection tower, comprising a molten salt electrolysis furnace, a pressure ring 1, and a guide slider 2;

[0024] The core equipment for high-purity titanium production, the molten salt electrolysis furnace, is mainly divided into three parts: the electrolysis cell, the transition section, and the collection tower. The electrolysis cell and the transition section are fixed devices, while the collection tower is a device for collecting and transferring purified materials. The round opening of the transition section is equipped with a latch, and the bottom of the collection tower is equipped with a buckle. The molten salt electrolysis furnace is existing technology and will not be described in detail here.

[0025] Several guide sliders 2 are provided, and all guide sliders 2 are set on the outer periphery of the pressure ring 1 and are evenly distributed along the circumference. The guide sliders 2 have a constricted structure from top to bottom. The lower surface of the pressure ring 1 is provided with a screw hole, which is used to connect the transition section. The screw hole is a blind hole 5 that does not penetrate. A bolt is screwed into the internal thread of the blind hole 5. The pressure ring 1 and the transition section are threadedly connected by the bolt and the blind hole 5 to form an integral structure. Several guide sliders 2 are connected to the pressure ring 1 by welding.

[0026] The upper and lower surfaces of the pressure ring 1 are respectively provided with sealing ring grooves 3. The diameter of the upper surface sealing ring groove 3 is larger than the diameter of the lower surface sealing ring groove 3. A sealing gasket 4 is embedded in the sealing ring groove 3.

[0027] This design can form a stepped sealing structure. The larger diameter groove on the upper surface facilitates the installation and positioning of the sealing gasket 4, while the smaller diameter groove on the lower surface allows the sealing gasket 4 to be more evenly compressed by bolt tightening when the pressure ring 1 is connected to the transition section or collection tower, thereby enhancing the sealing effect and effectively preventing leakage of media such as molten salt vapor and inert gas during the production of high-purity titanium. At the same time, it can adapt to different pressure environments when the collection tower is connected to the transition section, ensuring high airtightness inside the device, preventing outside air from entering and affecting the purity of high-purity titanium, and preventing safety hazards caused by abnormal internal pressure, thus improving the stability and reliability of equipment operation.

[0028] By welding a guide slider 2 every 90 degrees to the outer edge of the pressure ring 1 to form an integral structure, the guide slider 2 is prone to weld breakage and deformation when the collection tower comes into contact with the guide slider 2 due to its small force-bearing area. At the same time, the buckle at the lower edge of the collection tower and the locking buckle at the upper edge of the transition section need to be manually aligned, which takes a long time.

[0029] Example 2, based on Example 1, please refer to... Figure 2 Several guide sliders 2 are connected to the pressure ring 1 by turning and forming in one piece. The gap between several guide sliders 2 is used to accommodate the locking buckle of the transition section and to align with the buckle at the bottom of the collection tower.

[0030] The entire structure is machined in one piece, which increases the number of guide sliders 2 and the force-bearing area. The space between the guide sliders 2 and the sliders is reserved for the lower edge buckle of the collection tower. This design allows the lower edge of the collection tower to completely overlap with the pressure ring 1. However, the corners of the guide sliders 2 are right angles, which means that when the lower edge buckle of the collection tower contacts it, it cannot slide directly into the reserved position, resulting in buckle weld failure and deformation.

[0031] Example 3, based on Examples 1 and 2, please refer to... Figure 3 The guide slider 2 has a chamfer to guide the lower edge of the collection tower to slide into the reserved position for precise alignment. The chamfer is 45 degrees.

[0032] By designing the corner of the guide slider 2 at a 45-degree angle, the lower edge buckle of the collection tower can accurately slide into the reserved position when it contacts the side of the guide slider 2, thereby achieving precise alignment between the lower edge buckle of the collection tower and the upper edge lock of the transition section. At the same time, it also achieves precise alignment between the lower edge of the collection tower and the pressure ring 1, solving the problems of long alignment time and inaccuracy mentioned above. It has now been successfully applied in high-purity titanium electrolysis furnace equipment.

[0033] Working Principle: When the high-purity titanium collection tower is transferred to the position ring device, the descent and repositioning process, through the constriction structure of the guide slider 2, ensures that the center of the bottom circular opening of the high-purity titanium collection tower is on the same vertical line as the center of the pressure ring 1. This allows the axis of the high-purity titanium material inside the collection tower to coincide with the vertical line, enabling the electrode hangers and high-purity titanium material inside the tower to freely pass through the positioning device and enter / exit the electrolytic cell below without scraping the wall. The gap between the guide sliders 2 allows the locking buckles set around the circular opening of the transition section to pass through, corresponding one-to-one with the buckles set around the circular opening of the bottom of the collection tower, thus locking the positioned collection tower and the transition section together. The pressure ring 1 has upper and lower surfaces, each equipped with a sealing gasket 4. The lower surface of the pressure ring 1 has a circle of evenly distributed, non-penetrating blind holes 5. Fastening bolts connect and tighten to the positioning ring device through the screw holes around the circular opening of the transition section, making the positioning ring and the transition section a single unit.
