Description

Technical Field

[0001] This invention belongs to the field of reduction furnace technology, specifically relating to a cooling device for the cover of a sponge titanium reduction furnace. Background Technology

[0002] The existing magnesium reduction furnaces in the production of sponge titanium have the following problems: Liquid TiCl4 is introduced into the furnace through the cover to react with Mg inside the furnace. This reaction is exothermic, and as the exothermic reduction proceeds, the temperature and pressure inside the furnace increase. The temperature at the cover can reach up to 850℃ during the reduction process. This temperature increase leads to excessively high cover temperature, increasing the risk of cover deformation and even burn-through, thus shortening its service life. Furthermore, the rapid vaporization of TiCl4 further increases the furnace pressure, requiring a reduction in the TiCl4 feeding rate to avoid excessive pressure. This slows down the overall reaction rate and affects production efficiency. The existing sponge titanium reduction furnace cover lacks a cooling device and relies on natural air cooling. The cover remains overheated over a long period, requiring replacement after a certain number of uses. The increased furnace pressure caused by high temperatures slows the TiCl4 feeding rate, prolongs the reaction time, and reduces production efficiency. Therefore, it is essential to provide a simple, heat-dissipating, leak-proof, and easily detachable cooling device for the sponge titanium reduction furnace cover. Summary of the Invention

Detailed Implementation

[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-12 As shown, the cooling device for the large cover of the sponge titanium reduction furnace includes a large cover 1, a cooling pipe 2, and a fan 3. The large cover 1 is equipped with a cooling pipe 2, with an inlet and an outlet at each end. The cooling pipe 2 is movably connected to the large cover 1. The fan 3 is located above the large cover 1 and is connected to the large cover 1 through a movable adjustment mechanism 7.

[0031] The cooling pipe 2 includes an arc pipe section 21 and a straight pipe section 22. The arc pipe section 21 is arranged with left and right sides spaced apart, and the arc pipe sections 21 are connected to each other through the straight pipe section 22.

[0032] The straight tube section 22 is provided with spiral fins 4 on its exterior, and the arc tube section 21 is provided with a plurality of toothed fins 5 on its exterior.

[0033] The spiral fin 4 includes side plates 41 disposed on the upper and lower sides of the outside of the straight tube section 22. A fin plate 42 is disposed on the inner side of each side plate 41. One end of each fin plate 42 is connected to the side plate 41 by a corresponding mounting bolt 43. A "Z"-shaped connecting plate 44 is disposed on the inner side of each fin plate 42. Both ends of the connecting plate 44 are connected to the fin plate 42 by a corresponding connecting bolt 45.

[0034] The inner side of the arc tube section 21 is provided with a movable connecting device 6, and the cooling pipe 2 is movably connected to the cover 1 through the movable connecting device 6.

[0035] The movable connecting device 6 includes a sleeve 61 mounted on the large cover 1. A spring seat 62 is mounted below the sleeve 61. A spiral groove 63 is mounted on the front of the sleeve 61. A vertical groove 64 and a positioning groove 65 are respectively mounted at the upper and lower ends of the spiral groove 63. A movable knob 66 ​​is mounted above the sleeve 61. An inner rod 67 is mounted inside the movable knob 66. A positioning pin 68 is mounted on the front of the inner rod 67 corresponding to the spiral groove 63.

[0036] In this embodiment, the working principle of the cooling pipe and the cover installation is as follows: The cooling pipe includes an arc pipe section and a straight pipe section. A movable connecting device is provided inside the arc pipe section. First, the cooling pipe is placed on top of the cover and the movable knob is connected to the sleeve. Then, the cooling pipe is moved downward so that the positioning pin of the inner rod smoothly enters the spiral groove through the vertical groove. Then, the movable knob is rotated to drive the inner rod and the positioning pin to rotate along the spiral groove. The inner rod presses down on the spring seat. When the positioning pin is in the positioning groove at the lower end of the spiral groove, the movable knob is released. Under the elastic force of the spring seat, the inner rod is pushed upward so that the positioning pin falls completely into the positioning groove, locking the positioning pin and completing the installation of the cooling pipe and the cover. In actual use, for better results, a sleeve can be fixedly connected inside the arc pipe section. The movable knob is located at the upper end of the sleeve, the inner rod is located inside the sleeve, and the positioning pin is located at the lower end of the sleeve. The upper edge of the sleeve limits the movable knob, and the lower edge of the sleeve limits the positioning pin.

[0037] This invention relates to a cooling device for the cover of a titanium sponge reduction furnace. In use, this invention incorporates cooling pipes 2 at the bottom of the furnace cover 1 to cool it. This effectively solves the problems of increased furnace temperature leading to deformation or even burn-through of the furnace cover in existing magnesium reduction furnaces used in titanium sponge production, as well as the slowdown in overall reaction speed due to increased temperature, thus affecting production efficiency. Furthermore, this invention lays cooling pipes 2 at the bottom of the magnesium reduction furnace cover 1 and adds a fan 3 above the cooling pipes 2 for active heat dissipation, effectively reducing the temperature at the bottom of the cover 1 and cooling it to prevent... High-temperature deformation increases the service life of the cover 1; it also increases the feeding speed and improves the overall production efficiency of the reactor; in addition, the cooling water pipe 2 adopts finned tubes, with the fins in contact with the bottom of the cover, avoiding burn-through damage and leakage of the water pipes; furthermore, the fins greatly increase the heat dissipation area and improve heat exchange efficiency; the cooling pipe 2 of this invention is movably placed at the bottom of the cover 1, and the fan 3 is set above the cover 1 through the movable adjustment device 7, which can be easily removed after use without affecting the normal operation of the distillation process; this invention has the advantages of simple structure, good heat dissipation effect, avoidance of damage and leakage, and convenient installation of detachable structure.

[0038] Example 2

[0039] like Figure 1-12 As shown, the cooling device for the large cover of the sponge titanium reduction furnace includes a large cover 1, a cooling pipe 2, and a fan 3. The large cover 1 is equipped with a cooling pipe 2, with an inlet and an outlet at each end. The cooling pipe 2 is movably connected to the large cover 1. The fan 3 is located above the large cover 1 and is connected to the large cover 1 through a movable adjustment mechanism 7.

[0040] The fan 3 is provided with mounting plates 31 on both the left and right sides, and crossbars 32 are provided on both the upper and lower sides of the mounting plates 31. Mounting seats 8 are provided on the outer side of the mounting plates 31. Slots 10 are provided inside the mounting seats 8 corresponding to the crossbars 32. Movable slots 11 are provided on both the upper and lower front sides of the mounting seats 8. Positioning bolts 12 are provided in front of the movable slots 11. The mounting seats 8 are connected to the movable adjustment mechanism 7.

[0041] The movable adjustment mechanism 7 includes a base 71, which is connected to the cover 1 by a fixing bolt 72. A column 73 is provided on the top of the base 71. A rack 74 is provided on one side of the column 73. A movable sleeve 75 is provided on the outside of the top of the column 73. A connecting seat 76 is provided on the left side of the movable sleeve 75. The connecting seat 76 is connected to the mounting seat 8 by a fixing screw 9.

[0042] A power adjustment box 77 is provided on the right side of the movable sleeve 75, and a manual control panel 78 is provided in front of the power adjustment box 77.

[0043] The power regulating box 77 has a power gear 79 inside that meshes with the rack 74 at the corresponding position. The power gear 79 has a main shaft 710 inside and is powered to the manual disk 78 through the main shaft 710.

[0044] In this embodiment, the working principle of the movable adjustment mechanism is as follows: the movable adjustment mechanism is connected to the cover through the base and fixing bolts. The fan is placed above the movable adjustment mechanism, and the mounting plates and crossbars at both ends correspond to the inner cavity and slot of the mounting seat. The fan is moved downward, and then the fan is locked by the positioning bolts on the front and rear side walls of the mounting seat. The position of the positioning bolts can be adjusted through the movable slot, which can adjust the positioning position of the fan and is easy to adapt to different specifications of fans, making it highly practical. After the fan is installed, the height of the fan can also be adjusted by the manual disc. Rotating the manual disc drives the power gear to rotate through the main shaft, so that the power gear moves along the rack, thereby driving the movable sleeve to move along the column, thus realizing the adjustment of the fan height and adapting to different heat dissipation requirements. Of course, in actual use, in order to save time and manpower, an electric structure such as a motor or other equivalent device can be used to replace the movement of the manual disc driving the power gear.

In use, this invention incorporates cooling pipes 2 at the bottom of the furnace cover 1 to cool it. This effectively solves the problems of increased furnace temperature leading to deformation or even burn-through of the furnace cover in existing magnesium reduction furnaces used in titanium sponge production, as well as the slowdown in overall reaction speed due to increased temperature, thus affecting production efficiency. Furthermore, this invention lays cooling pipes 2 at the bottom of the magnesium reduction furnace cover 1 and adds a fan 3 above the cooling pipes 2 for active heat dissipation, effectively reducing the temperature at the bottom of the cover 1 and cooling it to prevent...
