Description

Technical Field

[0001] This utility model belongs to the field of reactor technology, specifically relating to an input component and a sponge titanium reactor. Background Technology

[0002] In the production of sponge titanium, titanium tetrachloride and metallic magnesium react at high temperature to produce sponge titanium and magnesium chloride, and further magnesium chloride and unreacted metallic magnesium are added. Existing reactors for producing sponge titanium using the magnesium reduction method have flanges on the upper edge of the cylinder directly welded to the outer wall of the cylinder, supporting the cylinder and suspending it on the furnace edge. Magnesium chloride tubes are located outside the cylinder and connected to it. For example, Chinese patent CN1831163A discloses a reactor for producing sponge titanium, which consists of a cylinder, an outer cylinder, an upper flange, a lower flange, stiffening plates, magnesium chloride tubes, and connecting pipes. The upper flange is connected to the upper edge of the cylinder, and the upper flange is connected to the upper end of the outer cylinder. The lower end of the outer cylinder is connected to the lower flange. Stiffening plates are provided between the upper and lower ends of the outer cylinder and the upper and lower flanges. Magnesium chloride tubes are located on the inner bottom and inner wall of the cylinder, and the upper end of the magnesium chloride tubes is connected to the connecting pipes. Chinese patent CN207749168U discloses a cylindrical body for a titanium sponge reduction reactor, including a cylindrical body with a flange skirt welded at the opening of the cylindrical body. The flange skirt is composed of an upper flange, a lower flange, and stiffeners. Multiple stiffeners are arranged and fixed in a ring along the opening of the cylindrical body and connect the upper flange and the lower flange. It also includes a liquid inlet pipe, which is fixed in the flange skirt and extends into the cylindrical body. The flange skirt is also provided with a cooling structure.

[0003] Magnesium chloride tubes need to be replaced after a period of use. However, since the magnesium chloride tubes are welded to the cylinder, the weld joint needs to be burst during replacement, which causes the hole at the connection to become larger and larger. This not only increases the difficulty of sealing but also affects the strength of the cylinder. Summary of the Invention

[0043] like Figure 1 and Figure 2 As shown, the sponge titanium reactor of this embodiment includes a cylindrical body 10 for reaction, with a connection hole 11 (generally a round hole) on the cylindrical body 10. A cap 12 is provided at the bottom of the cylindrical body 10, and a magnesium chloride tube 31 extends to the inside of the cap 12. A connecting assembly 20 is provided on the cylindrical body 10, which includes an upper flange 21, a lower flange 22, and a stiffener 23. The stiffener 23 is connected to the upper flange 21 and the lower flange 22 at both ends. In addition to reinforcing the upper flange 21 and the lower flange 22, the stiffener 23 can also distribute part of the weight of the cylindrical body 10 supported by the lower flange 22 onto the upper flange 21. A lifting lug 24 is connected to the outer end of the stiffener 23 for lifting the cylindrical body 10 of the reactor. An input assembly 30 is also provided on the cylindrical body 10.

[0044] Among them, such as Figure 2 As shown, the input component 30 includes a magnesium chloride tube 31 disposed on the inner wall of the reactor cylinder 10, the magnesium chloride tube 31 being tightly attached to the inner wall, the upper end of the magnesium chloride tube 31 being a closed end and the lower end being an open end; a sleeve 32 disposed on the outer wall of the reactor cylinder 10, the sleeve 32 and the magnesium chloride tube 31 being respectively disposed on both sides of the connection hole 11; and a connecting pipe 33 inserted into the sleeve 32, the inner end of the connecting pipe 33 extending into the magnesium chloride tube 31 and being fixed to the magnesium chloride tube 31 (generally by welding), and the outer end being provided with a connecting flange 331 for connecting to an external feeding pipe.

[0045] In use, the sleeve 32 is welded to the outer wall of the cylinder 10, and the connecting pipe 33 is inserted into the sleeve 32. The inner side of the connecting pipe 33 passes through the connecting hole 11 and is welded to the magnesium chloride pipe 31. When disassembly is required, the connecting pipe 33 can be removed by simply breaking the weld between the connecting pipe 33 and the magnesium chloride pipe 31. The connecting pipe 33 is easy and quick to replace, which effectively improves work efficiency.

[0046] The material of the connecting pipe is selected from one of SUS321, SUS310, SUS304, SUS31, and HRJY1. In this embodiment, the material of the connecting pipe is HRJY1. All of the above materials are commercially available products. "HR" refers to heat-resistant steel, JY is the abbreviation of Jiuyi Company, and HRJY1 is the model number of the commercially available product.

[0047] Furthermore, in some embodiments of this utility model, combined with Figure 2 As shown, the input component 30 also includes an expansion joint 34, which is fitted onto the connecting pipe 33 and is sealed and welded to the sleeve 32 and the connecting pipe 33 to ensure a sealing effect. The expansion joint 34 effectively compensates for the additional stress caused by temperature difference and mechanical vibration, and improves the stability of the input component 30. At the same time, the connecting pipe 33 is fixed to the external connector. Since there is a large gap between the connecting pipe 33 and the connecting hole 11, the end of the connecting pipe 33 vibrates greatly. Therefore, the expansion joint 34 is placed outside the connecting component 20. This design can improve the stability of the connecting pipe 33 over a large range.

[0048] To facilitate the installation of the connecting pipe 33, the inner diameter of the sleeve 32 is slightly larger than the outer diameter of the connecting pipe 33. Since there is a gap between the connecting pipe 33 and the connecting hole 11, the heat inside the reactor tube 10 will overflow to the sleeve part along the gap. Therefore, a sealing element 35 is provided between the sleeve 32 and the connecting pipe 33. The sealing element 35 is made of high temperature and corrosion resistant materials, such as commercially available refractory castables and thermal insulation cotton. It can not only play a role in thermal insulation and sealing, but also prevent the sleeve from deforming due to heat.

[0049] In addition, it should be noted that since the connecting pipe 33 and the sleeve 32 are in clearance fit and there is a gap at the connecting hole 11, the gap is very easy to cause air ingress. Air ingress will cause adverse problems such as oxidation of the sponge titanium agglomerate. The design of the sealing element 35 mentioned above effectively solves the problem of air ingress, so that the reactor maintains a certain value due to the pressure difference between the inside and outside, avoiding deformation and leakage of the cylinder 10, thereby helping to extend the service life of the reactor.

[0050] exist Figure 2In this design, a positioning plate 36 is provided between the sleeve 32 and the connecting pipe 33. The positioning plate 36 is vertically welded and its end does not contact the connecting pipe. Furthermore, one end of the sealing element 35 does not extend to the positioning plate 36, while the other end extends to the inside of the expansion joint 34, which further extends the sealing length, resulting in a good sealing effect and further reducing the possibility of air intake.

[0051] The reaction temperature of the reactor of this utility model is as high as 1000℃ or more (heated in a heating furnace). Therefore, the reactor needs to be cooled. Cooling water pipes 25 are provided on the upper flange 21 and the lower flange 22. The cooling water pipes 25 are connected to external water pipes to realize the circulation of cooling water (which can be tap water, fire water and other water) to achieve the purpose of heat dissipation of the cylinder 10.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
