Description

Technical Field

[0001] This invention relates to the field of non-ferrous metallurgical production technology, specifically to a reactor bottom separation device in the production process of sponge titanium. Background Technology

[0002] In the production of sponge titanium, especially in the Type I furnace process, a removable bottom is placed at the bottom of the reactor. This serves to bear weight and provide space for magnesium chloride storage, ensuring the normal discharge of magnesium chloride during reduction and the smooth ejection of the titanium agglomerate during dismantling at the end of distillation. Currently, the impurity content of sponge titanium products from various manufacturers is low, with grade 0 products accounting for over 70%. This means that impurity content is no longer the primary factor influencing the market share of each manufacturer. Based on recent years of technological advancements in sponge titanium production and feedback from downstream customers, sponge titanium with good porosity is increasingly favored. Good porosity (low bulk density) makes it easier for downstream customers to press and mold, preventing "bomb shedding" and thus improving the yield rate after smelting. The low bulk density of sponge titanium products indicates a loose structure in the titanium boluses generated during the reduction process. It also signifies more thorough impurity removal (magnesium chloride) during distillation and less damage to the cutting tools during the various stages of fine crushing of the sponge titanium. In other words, producing loosely structured titanium boluses during the reduction process is beneficial to both the company and the industry, making this research direction crucial for increasing the market share of sponge titanium products for various enterprises. Currently, many companies are improving the live bottom of the reactors used in sponge titanium production, primarily by adding upright frustums or grids (also known as conical live bottoms) to the live bottom. During the reduction process, the sponge titanium mainly accumulates around the frustums or grids, resulting in a hollow center and loose structure in the titanium boluses. Ultimately, the bulk density of the sponge titanium product can be as low as 1.3 t / m³. 3 However, using the aforementioned type of removable bottom presents the problem of adhesion between the removable bottom and the titanium bulge, making separation difficult. Some companies address this issue by hoisting the titanium bulge along with the adhered removable bottom to a hydraulic shearing machine, starting the shearing from the cap of the titanium bulge. When the shearing reaches the cutout position of the titanium bulge, it disperses into three pieces, thus naturally separating the removable bottom from the titanium bulge. However, this method introduces further problems: the shearing machine may accidentally cut the removable bottom (damaging the cutter and the removable bottom); and when shearing to the cutout position of the titanium bulge, there is a chance that the titanium bulge will not disperse, resulting in failed separation. Other companies directly adopt a conventional dragging method, which causes deformation of the removable bottom during separation, rendering it unusable and increasing the manufacturing cost of the sponge titanium. Summary of the Invention

[0003] The purpose of this invention is to provide a reactor bottom separation device in the production process of sponge titanium, so as to solve the problem mentioned in the background art that the bottom of the sponge titanium is deformed during separation, making it unusable and increasing the manufacturing cost of sponge titanium.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A reactor bottom separation device for sponge titanium production includes a separation device support and a transport trolley disposed at the bottom of the separation device support;

[0006] The separation device support is equipped with several uniformly spaced, ring-shaped cutting hydraulic cylinders, and each set of cutting hydraulic cylinders has a cutting blade connected to its piston rod.

[0007] The transport trolley is equipped with drive wheels at the four corners of its bottom, and trolley support frames for fixing the titanium blocks are symmetrically arranged on both sides of its top.

[0008] Preferably, the mop of the cutter is inserted into the piston rod of the hydraulic cylinder of the cutter, and the outer wall is locked by fixing bolts.

[0009] Preferably, the top surface of the transport trolley is provided with an adjusting screw for adjusting the support frame of the transport trolley.

[0010] Preferably, the top surface of the trolley support frame is arc-shaped and adapted to the outer wall dimensions of the fixed titanium block.

[0011] Preferably, the top surface of the trolley support frame is provided with an anti-slip pad.

[0012] Preferably, the anti-slip mat is made of silicone material and has a thickness of 3-5mm.

[0013] Preferably, the surface of the anti-slip mat is provided with anti-slip protrusions.

[0014] Preferably, a drive motor is installed at the central shaft of each of the vehicle's drive wheels.

[0015] Preferably, the drive motor on each of the vehicle's drive wheels is a synchronous motor.

[0016] Preferably, each of the drive motors is mounted on the bottom of the transport trolley via a connecting bracket.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In the production process of sponge titanium, the reactor bottom separation device can replace the method of removing the bottom by shearing and dispersing the titanium lumps. This avoids the problems of failure to remove the titanium lumps due to non-dispersion and accidental cutting of the bottom. The addition of a cutting method before the conventional dragging and removal process can separate the bottom from the titanium lumps, effectively avoiding deformation of the bottom during the dragging process and thus avoiding increased production costs.

[0019] 2. In the reactor bottom separation device of this sponge titanium production process, several uniformly spaced hydraulic cylinders and cutters are installed on the separation device support, which allows for convenient cutting of titanium lumps in the reactor when needed, improving operational efficiency and convenience. Drive wheels are installed at the four corners of the bottom of the transport trolley, allowing the trolley to move flexibly in different terrains, enhancing its adaptability and convenience. Symmetrical support frames for fixing the titanium lumps are set on both sides of the top of the transport trolley, facilitating the fixing and support of the titanium lumps and ensuring stability and safety during transportation and operation.

[0020] 3. In the reactor bottom separation device of this sponge titanium production process, the cutting blade's padding and the piston rod of the cutting blade hydraulic cylinder are interlocked and locked with the outer wall by fixing bolts, which facilitates installation or disassembly. When one set is damaged, it can be replaced individually, saving maintenance costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0027] A reactor bottom separation device for the production of sponge titanium, such as Figure 1 As shown, the device includes a separation device support 1 and a transport trolley 9 located at the bottom of the separation device support 1. Several uniformly spaced, ring-shaped cutting hydraulic cylinders 2 are mounted on the separation device support 1, with a cutting blade 3 connected to the piston rod of each set of cutting hydraulic cylinders 2. Trolley drive wheels 8 are installed at the four corners of the bottom of the transport trolley 9, and trolley support frames 6 for fixing the titanium agglomerate 5 are symmetrically arranged on both sides of the top of the transport trolley 9. Several uniformly spaced, ring-shaped cutting hydraulic cylinders 2 are mounted on the separation device support 1. The cutter 3 allows for convenient cutting of the titanium lumps in the reactor when needed, improving operational efficiency and convenience. Drive wheels 8 are installed at the four corners of the bottom of the transport trolley 9, enabling the trolley to move flexibly in different terrains, enhancing its adaptability and convenience. Symmetrical support frames 6 for fixing the titanium lumps 5 are installed on both sides of the top of the transport trolley 9, facilitating the fixing and support of the titanium lumps and ensuring stability and safety during transportation and operation.

[0028] Furthermore, the mop of the cutter 3 and the piston rod of the cutter hydraulic cylinder 2 are inserted into each other, and the outer wall is locked by fixing bolts, which facilitates installation or disassembly. When one set is damaged, it can be replaced individually, saving maintenance costs.

[0029] Specifically, the top surface of the trolley 9 is equipped with an adjusting screw 7 for adjusting the trolley support frame 6, which can adjust the position of the trolley support frame 6 and is easy to use.

[0030] It is worth noting that the top surface of the trolley support frame 6 is arc-shaped and matches the outer wall size of the fixed titanium block 5. The top surface of the trolley support frame 6 is equipped with an anti-slip pad 61, which is made of silicone material and is 3-5mm thick. The anti-slip pad can increase the friction between the support frame and the titanium block, prevent the titanium block from sliding during transportation, and increase the practicality of the equipment.

[0031] The anti-slip mat 61 has anti-slip protrusions on its surface, which further enhances the anti-slip effect, prevents the titanium block from sliding during transportation, and improves the safety of the equipment.

[0032] In addition, a drive motor 81 is installed at the central shaft of each trolley drive wheel 8. The drive motor 81 on each trolley drive wheel 8 is a synchronous motor. Each drive motor 81 is installed at the bottom of the trolley 9 through a connecting seat 82, which increases the power and stability of the trolley, allowing the trolley to move and operate more flexibly and improving the efficiency of the equipment.

[0033] This invention can replace the method of removing the live bottom by shearing and dispersing the titanium lumps, avoiding the problems of failure to remove the live bottom due to the titanium lumps not being dispersed and accidental cutting of the live bottom. By adding a separation method before the conventional dragging and removal, the live bottom is separated from the titanium lumps first, which effectively avoids deformation of the live bottom during the dragging process, thereby avoiding increased production costs.

[0034] The working principle of the reactor live bottom separation device in the production process of sponge titanium of the present invention is as follows: The titanium lumps 5 containing live bottoms are hoisted onto the transport trolley, and then the transport trolley is driven to the bottom of the separation device support 1 and initially aligned. Then, the transport trolley support frame 6 is slowly adjusted by the trolley adjusting screw 7 to align the bottom of the titanium lumps with the cutting plane 4. Then, the cutting hydraulic cylinder 2 slowly extends the cutting blade 3 to cut into the bottom of the titanium lumps, initially separating the live bottom of the titanium lumps 5 from the titanium lumps 5. After the initial separation is completed, the hydraulic cylinder 2 is controlled to retract the cutting blade 3, and the transport trolley 9 is driven to an open position. The live bottom can be removed by conventional dragging.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
