Description

Technical Field

[0001] This invention relates to the field of non-ferrous metal smelting technology, and more specifically, to a device and method for preventing foreign objects from entering sponge titanium lumps. Background Technology

[0002] Currently, the main production method for sponge titanium is the reduction of titanium tetrachloride by liquid magnesium in a closed reactor. This process involves a complex gas-liquid multiphase reaction. After the reaction, low-valence titanium compounds, magnesium, and magnesium chloride remain on the surface of the reactor flange. Oxygen- and nitrogen-rich climbing titanium deposits are formed on the upper side of the reactor's inner wall. These deposits require manual cleaning during removal. During cleaning, low-valence titanium compounds, titanium nitride, and other foreign matter can easily fall onto the surface of the titanium deposits and into the surface pores, causing contamination of the sponge titanium and posing a risk of foreign matter introduction.

[0003] To address the issue of foreign objects falling during the removal of titanium sponge, patent CN118253562A discloses a device to prevent foreign objects from falling during the removal process. The device includes a movable support and an anti-fall device, which comprises an umbrella column, an umbrella shaft, umbrella ribs, and an umbrella canopy. The umbrella shaft slides along the umbrella column to control the opening and closing of the umbrella ribs and canopy, forming a protective area above the titanium mass to prevent foreign objects from falling. This solution employs an inverted umbrella-like structure, using the opening and closing of the umbrella canopy to block and collect foreign objects.

[0004] However, the aforementioned umbrella-shaped structure still has certain limitations in practical applications: the umbrella ribs and canopy structure are relatively complex, requiring high precision and reliability in the manufacturing process; furthermore, the opening and closing mechanism of the canopy may become clogged with foreign objects during long-term use, affecting operational flexibility. In addition, a traditional method involves laying a canvas on top of the titanium mass, but foreign objects can easily fall onto the titanium mass when the canvas is removed, and operators need to enter and exit the reactor, posing a significant safety risk. Summary of the Invention

[0005] In view of this, the present invention aims to provide a device and method for preventing foreign objects from entering the sponge titanium lumps to solve the problems in the prior art where foreign objects easily fall onto the surface of the titanium lumps and where operators need to enter and exit the reaction vessel, posing safety risks.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] A device for preventing foreign objects from entering a sponge titanium agglomerate includes a flexible blocking component, an expandable support component, and a traction component;

[0008] The flexible blocking component and the expandable support component are connected. After the expandable support component is inflated, it can fit against the inner wall of the reactor and drive the flexible blocking component to unfold, forming a pocket-shaped structure inside the reactor to receive foreign objects.

[0009] The traction member is disposed on the flexible blocking member and / or the expandable support member, for fixing the device inside the reactor and removing the device from the reactor;

[0010] The expandable support is provided with an inflation / deflation port for inflating or deflating the expandable support.

[0011] In some embodiments, the flexible barrier is fireproof cloth.

[0012] In some embodiments, the expandable support is an annular airbag, which is disposed on the outer edge of the fireproof cloth. After inflation, the outer wall of the annular airbag fits against the inner wall of the reactor, achieving circumferential fit.

[0013] In some embodiments, the outer edge of the fireproof cloth is wrapped with an annular airbag to form an integrated pocket-shaped structure.

[0014] In some embodiments, the traction member is a pull strap, one end of which is connected to a flexible blocking member and / or an expandable support member, and the other end of which is fixed to the opening of the reactor by a pull hook.

[0015] In some embodiments, the number of pull straps is 2 to 8 sets, each set of pull straps includes two symmetrically arranged straps, and the multiple sets of pull straps are evenly distributed along the circumference of the expandable support.

[0016] In some embodiments, the inner diameter of the reactor is L1, 1000mm≤L1≤5000mm, and the cross-sectional diameter of the annular airbag in the inflated state is L2, 50mm≤L2≤500mm.

[0017] In some embodiments, a gas charging / discharging pipeline is also included, one end of which is connected to a gas charging / discharging port, and the other end extends to the outside of the reactor for connecting to an external gas charging device.

[0018] A method for preventing foreign objects from entering a sponge titanium slab, using the aforementioned device, includes the following steps:

[0019] S1: Place the device into the reactor and position it using the traction device;

[0020] S2: Inflate the expandable support through the inflation / deflation port, causing the expandable support to expand and adhere to the inner wall of the reactor, while simultaneously causing the flexible blocking component to unfold and form a pocket-shaped structure.

[0021] S3: Perform the cleaning operation of the climbing titanium, so that the climbing titanium and foreign objects fall into the pocket structure;

[0022] S4: Clean the reaction vessel;

[0023] S5: Remove the device from the reactor using the traction device.

[0024] Compared with existing technologies, the device and method for preventing foreign objects from entering sponge titanium lumps according to the present invention have the following advantages:

[0025] 1) Through the combination of flexible blocking components and expandable support components, a pocket-shaped structure is formed that fits the inner wall of the reactor after inflation. This structure can fully cover the area above the titanium block, effectively catching the titanium and foreign objects that fall on the wall during the cleaning process, preventing foreign objects from falling into the surface and pores of the titanium block, and ensuring the purity of the sponge titanium product.

[0026] 2) Operators only need to use the traction device to place, position, and remove the device, eliminating the need to enter or leave the reactor and thus eliminating safety risks;

[0027] 3) The expandable support can be remotely inflated and deflated by an external inflation device outside the reactor without entering the reactor, making the deployment and retraction of the device simple and easy, greatly improving the convenience of operation and work efficiency.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the described embodiments are only some, not all, of the embodiments of this invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Example 1

[0034] like Figure 1-2 As shown, this embodiment provides a device for preventing foreign objects from entering a sponge titanium agglomerate, including a flexible blocking member 1, an expandable support member 2, and a traction member 3;

[0035] The flexible blocking member 1 and the expandable support member 2 are connected. After the expandable support member 2 is inflated, it can fit against the inner wall of the reactor 100 and can drive the flexible blocking member 1 to unfold, forming a pocket-shaped structure inside the reactor 100 for receiving foreign objects.

[0036] The traction member 3 is disposed on the flexible blocking member 1 and / or the expandable support member 2, and is used to fix the device inside the reactor 100 and to remove the device from the reactor 100.

[0037] The expandable support 2 is provided with an inflation / deflation port 21 for inflating or deflating the expandable support 2.

[0038] Specifically, this invention, through the cooperation of the flexible blocking component 1 and the expandable support component 2, forms a pocket-shaped structure that fits the inner wall of the reactor 100 after inflation. This structure can fully cover the area above the titanium mass, effectively catching titanium and foreign objects that fall onto the wall during cleaning, preventing foreign objects from falling into the surface and pores of the titanium mass, thus ensuring the purity of the sponge titanium product. At the same time, operators only need to use the traction component 3 to complete the placement, positioning, and removal of the device without having to enter or leave the reactor 100, eliminating safety risks. In addition, the inflation and deflation operations of the expandable support component 2 are achieved through the inflation and deflation port 21, making the deployment and retraction of the device simple and easy, greatly improving the convenience of operation and work efficiency.

[0039] In some embodiments, the flexible barrier 1 is a fireproof cloth.

[0040] Specifically, the fireproof cloth has excellent high-temperature resistance and flame-retardant properties, effectively isolating sparks generated by knocking or friction during the process of climbing the titanium wall, preventing sparks from igniting the device or causing a fire in the titanium block, thus ensuring the safety of the production process. At the same time, the fireproof cloth is soft and can freely expand or contract with the expansion and contraction of the expandable support 2 without hindering the deformation of the expandable support 2, ensuring the reliability of the device's operation. In addition, the surface of the fireproof cloth is smooth, and foreign objects do not easily adhere to it. When removing the device, foreign objects can be smoothly removed along with the pocket-shaped structure, avoiding foreign object residue.

[0041] In some embodiments, the expandable support 2 is an annular airbag, which is disposed on the outer edge of the fireproof cloth. After inflation, the outer wall of the annular airbag fits against the inner wall of the reactor 100, achieving circumferential fit.

[0042] Specifically, after the annular airbag is inflated, it expands outward evenly in the circumferential direction. Its outer wall fits circumferentially with the inner wall of the reactor 100. On the one hand, this ensures the stable positioning of the device within the reactor 100 and prevents displacement or shaking during use. On the other hand, the fit between the annular airbag and the inner wall of the reactor 100 forms a complete circumferential closed barrier, which effectively intercepts all foreign objects generated during the cleaning process and prevents foreign objects from bypassing the edge of the device and falling into the titanium block.

[0043] In some embodiments, the outer edge of the fireproof cloth is wrapped with an annular airbag to form an integrated pocket-shaped structure.

[0044] Specifically, the outer edge of the fireproof cloth completely wraps around the annular airbag, integrating the fireproof cloth and the annular airbag into a single structure. This enhances the connection strength between the flexible blocking component 1 and the expandable support component 2, preventing them from detaching during use and causing device failure, thus improving the structural stability and service life of the device. On the other hand, the integrated pocket-like structure allows the fireproof cloth to be evenly stressed and smoothly unfold when the annular airbag expands, forming a fully open and sufficiently deep receiving space, effectively preventing foreign objects from slipping off the edge due to insufficient unfolding of the pocket-like structure. At the same time, the integrated structure facilitates the overall storage, retrieval, and maintenance of the device, simplifying the operation process.

[0045] Preferably, the annular airbag is made of high-temperature resistant rubber or PVC composite material.

[0046] In some embodiments, the traction member 3 is a pull strap, one end of which is connected to the flexible blocking member 1 and / or the expandable support member 2, and the other end of which is fixed to the opening of the reactor 100 by a pull hook.

[0047] Specifically, a pull strap is used as the traction component 3, which has a simple and reliable structure and low cost. The pull strap is fixed to the opening of the reactor 100 by a hook, allowing operators to position and fix the device from the outside without entering the reactor 100, making operation convenient and safe. At the same time, the pull strap has good flexibility and can bend freely during the insertion and removal of the device without interfering with the lifting and lowering of the device. The length of the pull strap can be adjusted according to the depth of the reactor 100, making it highly versatile. In addition, the hook fixation facilitates quick assembly and disassembly, improving work efficiency.

[0048] In some embodiments, the number of pull straps is 2 to 8 sets, each set of pull straps includes two symmetrically arranged straps, and multiple sets of pull straps are evenly distributed along the circumference of the expandable support 2.

[0049] Specifically, by setting multiple sets of evenly distributed circumferential straps, the device is subjected to uniform traction force within the reactor 100, ensuring that the device remains horizontal during placement, positioning, and removal, and preventing tilting of the device or spillage of foreign objects from the pocket structure due to uneven force. Each set of straps includes two symmetrically arranged straps, further improving the balance and reliability of traction. At the same time, the multiple sets of evenly distributed circumferential straps also help the expandable support 2 maintain uniform circumferential expansion during inflation, ensuring that the annular airbag fits snugly against the inner wall of the reactor 100, improving the sealing effect. In addition, the number of strap sets can be flexibly selected from 2 to 8 sets according to the actual size of the reactor 100 and the weight of the device, taking into account both the fixing effect and the ease of operation.

[0050] In some embodiments, the inner diameter of the reactor 100 is L1, 1000mm≤L1≤5000mm, and the cross-sectional diameter of the annular airbag in the inflated state is L2, 50mm≤L2≤500mm.

[0051] Specifically, the inner diameter L1 of the reactor 100 is limited to the range of 1000mm to 5000mm, covering most of the specifications and dimensions of U-shaped reactors in the field of sponge titanium production, giving the device good versatility and a wide range of applications. The cross-sectional diameter L2 of the annular gasbag in the inflated state is limited to the range of 50mm to 500mm. On the one hand, this ensures that the gasbag has sufficient structural strength to fit the inner wall of the reactor 100 and provide stable support. On the other hand, it avoids the gasbag cross-section being too large, which would lead to excessive inflation and affect the inflation and deflation efficiency. This design allows the annular gasbag to form a good fit and seal with the inner wall of the reactor 100 of different specifications after inflation, ensuring that the device can play an effective foreign matter interception function in various reactors. There is no need to design a separate device for each type of reactor, reducing manufacturing and management costs.

[0052] In some embodiments, a gas charging / discharging pipeline is also included, one end of which is connected to the gas charging / discharging port 21, and the other end extends to the outside of the reactor 100 for connecting to an external gas charging device.

[0053] Specifically, by setting up charging and discharging pipelines, operators can remotely charge and discharge the expandable support 2 from outside the reactor 100 using an external charging device, without having to enter the reactor 100, further reducing operational safety risks. The design of extending the charging and discharging pipelines to the outside of the reactor 100 ensures that the charging and discharging operations do not interfere with the insertion and removal of the device, improving operational convenience and efficiency. At the same time, the external charging device can provide a stable air pressure source as needed, ensuring that the expandable support 2 can expand quickly and fully, shortening the preparation time. In addition, the setting of the charging and discharging pipelines also facilitates rapid discharging in emergency situations, improving emergency response capabilities.

[0054] A method for preventing foreign objects from entering a sponge titanium slab, using the aforementioned device, includes the following steps:

[0055] S1: Place the device into the reactor 100 using the traction component 3 and position it;

[0056] S2: Inflate the expandable support 2 through the inflation / deflation port 21, so that the expandable support 2 expands and fits against the inner wall of the reactor 100, while driving the flexible blocking component 1 to unfold and form a pocket-shaped structure.

[0057] S3: Perform the cleaning operation of the climbing titanium, so that the climbing titanium and foreign objects fall into the pocket structure;

[0058] S4: Clean the reactor 100;

[0059] S5: Remove the device from the reactor 100 using the traction component 3.

[0060] Specifically, this operating method allows operators to operate the traction component 3 from outside the reactor 100 without having to enter the reactor 100, thus completely eliminating the safety hazards of working in confined spaces. Furthermore, this operating method can significantly shorten the operation time and improve production efficiency.

[0061] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
