Description

Technical Field

[0001] The invention relates to the technical field of titanium sponge production, and in particular to a method for removing titanium sponge cleanly after production without pollution. Background Art

[0002] In the current production method of sponge titanium, sponge titanium undergoes a chemical reaction in a closed container, using liquid magnesium to reduce liquid titanium tetrachloride to generate sponge titanium. This process is a disproportionation reaction. During the reaction process, the existence of a cold zone in the reactor; the reaction between steam and steam between the raw materials; especially in the later stage when the amount of magnesium is insufficient and the replacement reaction is not thorough, low-priced substances, commonly known as "black powder", will be generated. Although sponge titanium has a secondary reaction during the formation process, some black powder low-priced titanium particles that objectively do not undergo a secondary reaction will be scattered in the gaps between the container connections, such as the upper surface of the reactor flange; the gap between the large cover and the reactor wall. Another part is scattered on the climbing titanium and titanium lumps. This part of black powder and low-priced substances are flammable and easy to absorb moisture. When taking out the titanium lumps, if these substances exist, there will be a direct risk of danger and pollution of the titanium lumps. In addition, the climbing titanium formed near the pot mouth of the reactor often contains high levels of oxygen and nitrogen impurities. If this part of the material is not cleaned up in advance, once small particles fall into the pores of the titanium lump when taking this part of the material, it will be difficult to clean and select, which will invisibly increase the impurity content of the titanium lump and affect product quality.

[0003] In the existing method for removing titanium sponge from the production process without pollution or incomplete cleaning, some black powder and low-price titanium particles that have not undergone secondary reaction are easily scattered on the wall-climbing titanium and titanium lumps during the cleaning process or when the cleaning is not thorough. This may cause secondary pollution of the titanium lumps. Therefore, it is necessary to design a method for removing titanium sponge from the production process without pollution or incomplete cleaning to address the above problem. Summary of the invention

[0004] The purpose of the present invention is to provide a method for cleaning and removing sponge titanium without pollution after production, so as to solve the problem of the existing method for cleaning and removing sponge titanium after production proposed in the above-mentioned background technology. During the cleaning process or incomplete cleaning, some black powder and low-cost titanium particles that objectively do not undergo secondary reaction are easily scattered on the climbing titanium and titanium lumps, which may cause secondary pollution of the titanium lumps.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a method for pollution-free and clean removal of sponge titanium after production, comprising a reactor pot, a reactor pot flange and a head hanging ear, a reactor large cover is installed above the reactor pot, and a feeding system is arranged on the upper outer side of the reactor large cover, the finished products produced on the upper inner wall of the reactor pot include wall-climbing titanium, and the finished products produced at the lower part of the reactor pot include titanium lumps, a large cover bottom is fixed on the lower side of the reactor large cover, the reactor pot flange is fixed to the upper outer ring of the reactor pot, and a sealing rubber gasket is arranged between the reactor pot flange and the reactor large cover, the outer edge of the reactor pot flange is penetrated by fastening bolts, the head hanging ear is welded to the lower sides of the reactor pot, and a sieve plate is fixed at the middle and lower part of the reactor pot.

[0006] Preferably, the reactor cover and the reactor bottom are integrated, and the symmetry centers of the reactor cover and the reactor bottom coincide with the symmetry center of the reactor pot, and the reactor pot is barrel-shaped.

[0007] Preferably, the feeding system includes a feed port, a connecting flange and a feeding pipe. The feed port is arranged in the middle of the interior of the reactor cover and the bottom of the cover, and a connecting flange is installed above the feed port. The feeding pipe is connected above the connecting flange.

[0008] Preferably, the feeding pipe forms an integrated structure with the feeding port through a connecting flange, and the feeding port is communicated with the interior of the reaction kettle.

[0009] Preferably, the reactor pot flange is fixedly connected to the reactor pot, and the reactor pot flange is bolted to the reactor large cover through fastening bolts.

[0010] Preferably, two head lifting ears are provided, and the head lifting ears are symmetrical with respect to the vertical center line of the reaction kettle pot.

[0011] Preferably, the sieve plate is a circular structure, and the symmetry center of the sieve plate coincides with the symmetry center of the reaction kettle.

[0012] Preferably, the method for removing the titanium sponge from the production process without any pollution and cleanliness comprises the following steps:

[0013] S1: Invert the reactor, place the reactor mouth downward on a flat surface, and remove the fastening bolts and sealing gaskets;

[0014] S2 is dismantled upside down, and the head lifting lug is used to quickly lift the reactor pot and the reactor cover, and the reactor pot is turned upside down on another dry and clean surface;

[0015] S3 After pouring out and waiting for a certain period of time, the reactor is placed horizontally to clean the black powder, edge skin and oxygen-rich and nitrogen-rich sponge climbing titanium on the pot mouth. After cleaning to the standard, the reactor is hung upside down and the wall is knocked with a sledgehammer to clean some magnesium chloride crystals previously scattered on the upper surface of the titanium lump;

[0016] S4 is to take it upright, and then use a crane to turn the reactor pot over again, so that the mouth of the reactor pot is facing upwards and placed upright in the cover, so that the wall-climbing titanium and the titanium lump can be cleanly removed. This method is called the inverted dismantling and cleaning upright method.

[0017] Preferably, during the inversion step S1 and the inversion dismantling step S2, the reactor pot is inverted by using a crane to lift it upside down, and the tail end cover of the reactor pot is lifted by a crane chain, so that the reactor pot can be quickly separated from the reactor cover and lifted open.

[0018] Preferably, during the disassembly process of step S2, a certain amount of argon gas may be appropriately filled into the interior of the reaction kettle.

[0019] The present invention provides a pollution-free and clean method for removing titanium sponge after production, which has the following beneficial effects:

[0020] The pollution-free cleaning removal method for sponge titanium after production adopts the inverted dismantling, cleaning and straight removal method. This method is more scientific and practical, and can be operated by personnel. It reduces the uncertainty of influencing factors when taking sponge titanium lumps, and can prevent sponge titanium from being flammable and easy to absorb moisture, thereby improving safety, and effectively preventing impurities such as low-priced materials and distilled magnesium from contaminating the titanium lumps and causing secondary pollution. At the same time, it eliminates the risk of foreign matter such as distilled magnesium entering into sponge titanium, thereby effectively improving the yield and appearance quality of sponge titanium.

[0021] The present invention adopts a crane to cooperate with the head lifting ear of the reactor pot during the inverted dismantling, which fully considers the operability of personnel and can avoid secondary pollution of sponge titanium caused by improper method of removing titanium lumps during the normal dismantling; then some argon gas is appropriately filled into the pot, so that more or less black powder and low-priced particles formed in the process of sponge titanium reduction, especially the black powder and low-priced particles on the surface of the reactor pot mouth flange, can be directly scattered on the inner surface of the large cover through the inverted dismantling method; then the inverted cleaning method is adopted to effectively clean up the black powder, edge skin and oxygen-rich and nitrogen-rich sponge wall titanium at the pot mouth, and then continue to remove the reactor. The kettle should be hung upside down to facilitate the cleaning of some magnesium chloride crystals previously scattered on the surface of the titanium lump, which completely avoids the possibility of impurities falling into the pot when disassembling and removing the titanium lump, causing secondary pollution of the titanium lump, thereby improving the yield of finished products. Finally, the finished product is taken out by the positive removal method, and it is disassembled upside down to clean first and then taken out positively, which avoids the possibility of some black powder, low-priced particles and other impurities falling on the titanium lump during the cleaning process or incomplete cleaning during positive disassembly. Moreover, once these impurities fall on the surface of the titanium lump, it is difficult to clean them up, and it is also difficult to pick out small impurity particles, thereby ensuring that the impurities in the titanium lump do not increase and effectively ensuring the quality of sponge titanium products.
