Description

Technical Field

[0001] The utility model relates to the technical field of titanium sponge production, in particular to a distillation channel protective dredging device with a protective space. Background Art

[0002] During the inverted U-shaped process of sponge titanium, after the distillation is completed, argon needs to be backfilled from the cold end to the hot end, the rectified distillation furnace system needs to be restored to positive pressure and put in the argon protection process, and then the connecting channel connecting the cold end and the hot end is disassembled, and then the condensed materials at the hot end and the cold end are cleaned respectively and a blind plate is installed. After the hot end is cooled, a sponge titanium lump is obtained, and the cold end continues to be reduced for the next production step.

[0003] After the connecting channel is removed at the end of distillation, there is a certain probability that the argon gas is not backfilled successfully due to the blockage of the hot end channel. After the connecting channel is removed, the hot end channel will be blocked by condensate or the blockage will partially crack. At this time, since the hot end is still under negative pressure, a large amount of air will enter the hot end. The contact reaction between the air and the high-temperature sponge titanium will cause the sponge titanium to oxidize, resulting in product degradation or scrapping, which will also affect safety.

[0004] The purpose of this patent is to solve the problem of abnormal treatment such as blockage or leakage at the hot end of distillation, and provide a safe and effective device for subsequent backfilling treatment. It has certain applicability for condensing magnesium chloride at the hot end connecting pipe, and can effectively control backfilling and monitor pressure.

[0034] The substantial technical effects and implementation process of the technical solution hereof, i.e. the basic functions, are as follows:

[0035] The patent provides a protective dredging device for a distillation channel, as shown in the figure. If the hot end is blocked and cannot be backfilled at the end of distillation during the production process, or the hot end is not backfilled and the condensate in the hot end channel cracks during the removal of the connecting channel, and air enters, the connecting flange can be quickly connected to the hot end channel flange. During this period, the buffer box can completely cover the condensate that exceeds the flange surface at the hot end, and there will be no problem of the flange being unable to be installed. The pressure channel can be used to monitor the pressure in the hot end reactor. After the argon filling tube is installed in the argon filling channel, if there is a leak, argon can be filled through the argon filling tube, and the pressure measuring tube is observed to reach a positive pressure. If the channel is blocked, the argon filling tube can be opened under argon protection to open the dredging channel. After the channel is dredged, argon is continuously filled from the argon filling tube, and the pressure is observed from the pressure measuring tube until it reaches a positive pressure.

[0036] This utility model provides a protective dredging device for a distillation channel, and the beneficial effects of adopting the above technical solution are as follows:

[0037] This patent can effectively prevent a large amount of air from entering the hot end reactor in an emergency situation, causing oxidation of the product.

[0038] This patent can deal with the blockage problem of the hot end reactor connecting pipe in an argon environment, and can quickly backfill argon after treatment to protect the faulty furnace products.

[0039] This patent is also applicable to emergency disposal in similar situations at the cold end.

[0040] The patented method is simple to operate and can be quickly disassembled.

[0041] The connecting flange is connected to the distillation channel port, and the device is installed or disassembled using a handle. The buffer space can effectively hold the cleaned condensate and prevent the condensate beyond the distillation channel port from affecting the flange installation. The pressure measuring tube can effectively monitor the pressure change at the hot end. The argon filling port can be used to fill argon when the channel is unblocked or cracked. The unblocking and observation port play a key role in the emergency disposal process. The valve can be opened for unblocking and cleaning, and the internal situation of the channel can also be observed through the observation port.

[0042] Embodiment 2: As a further improved solution or parallel solution or optional independent solution, the valve is a hand valve. The substantial technical effect and implementation process of the technical solution here, i.e., the basic function, are as follows: the hand valve is convenient to open and close and safer.

[0043] Embodiment 3: As a further improved solution or parallel solution or optional independent solution, the protection flange 2 and the hot end flange 1 can be tightly connected. The substantial technical effect and implementation process of the technical solution here, i.e., the basic function, are as follows: tight connection can make the overall airtightness better.

[0044] Embodiment 4: As a further improved solution or parallel solution or optional independent solution, a further protective sleeve 8 extends outward from the protective flange 2, and the further protective sleeve 8 can cover the outer end surface of the hot end flange 1. The substantial technical effect and implementation process of the technical solution here, i.e., the basic function, are as follows: the solution can further increase the airtightness and protect the overall structure.

[0045] Embodiment 5: As a further improved solution or parallel solution or optional independent solution, a handle 4 is arranged on the buffer box 3. The substantial technical effect and implementation process of the technical solution here, namely the basic function, are as follows: the handle 4 facilitates the disassembly of the flange.

[0046] Embodiment 6: As a further improved scheme or parallel scheme or optional independent scheme, a distillation channel protective temporary protection method with a protective space is characterized in that the protective dredging device for a distillation channel with a protective space as described in any one of the above items is used, and the steps are as follows:

[0047] For example, if the hot end is blocked at the end of distillation during the production process and cannot be backfilled, or the hot end is not backfilled, causing the condensate in the hot end channel to crack during the removal of the connecting channel, and air enters;

[0048] The protective flange 2 is quickly connected to the hot end channel flange, i.e., the hot end flange 1. During this process, the buffer box 3 can completely cover the condensate on the hot end that exceeds the flange surface, and there will be no problem that the flange cannot be installed;

[0049] The pressure in the hot end reactor can be monitored using the pressure measuring channel 5;

[0050] After the argon filling tube is installed in the argon filling channel 6, argon can be filled through the argon filling channel 6 if there is leakage;

[0051] Observe whether the pressure gauge on the pressure measuring channel 5 reaches a positive pressure. If the channel is blocked, open the argon filling channel 6 and open the cleaning and observation channel 7 to dredge the channel under argon protection. After the channel is dredged, continue to fill argon from the argon filling channel 6 and observe the pressure on the pressure measuring channel 5 until it reaches a positive pressure.

[0052] Innovatively, each of the above effects exists independently, and a set of structures can be used to combine the above results.

[0053] It should be noted that the multiple solutions provided by this patent include the basic solution itself, which are independent of each other and do not restrict each other, but they can also be combined with each other without conflict to achieve multiple effects together.

[0054] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the protection required.
