A sponge titanium distillation heating passage easy to clean

Abstract

This utility model relates to an easy-to-clean heating channel for sponge titanium distillation. It includes a heating channel with a cleaning hammer inside. A large cover is located at the bottom of the heating channel, and a base plate is fixedly mounted on the bottom of the large cover. A heating mechanism is located on the underside of the base plate. The original first temperature-measuring thermocouple has been moved to the lower part of the heating channel for precise temperature measurement of easily condensing areas. A heating mechanism and a second temperature-measuring thermocouple are added below the base plate at the bottom of the heating channel to prevent heat diffusion from the heating channel to the base plate, thus preventing low-temperature condensation. Inside the heating channel, since the pull tabs cover the channel, any adhering substances only adhere to the pull tabs. When cleaning the adhering substances on the pull tabs, the cleaning hammer easily pushes the condensate along with the pull tabs into the bottom of the cleaning channel, making operation convenient.

Description

Technical Field

[0001] This utility model belongs to the technical field of sponge titanium heating furnace, specifically relating to an easy-to-clean sponge titanium distillation heating passage. Background Technology

[0002] Titanium sponge, a crucial raw material for titanium alloy processing, is primarily produced industrially using the magnesiothermal reduction method. However, the resulting sponge titanium contains significant amounts of impurities such as magnesium chloride, magnesium, and low-valent magnesium ammonium chloride (a component of titanium). These impurities must be removed during subsequent distillation in a distillation furnace. The heating channels within the distillation furnace generate condensate during distillation, requiring a cleaning device to remove this condensate and ensure the furnace's proper functioning.

[0003] The following problems exist in the existing sponge titanium heating furnace cleaning device during production: 1. At the connection between the bottom of the heating channel and the large cover, due to the low temperature of the large cover bottom plate, heat from the lower part of the heating channel is continuously conducted to the large cover bottom plate. During the distillation process with a large evaporation rate, the actual temperature at the bottom of the heating channel is lower than the required 750℃. However, because the actual position of the temperature measuring thermocouple is located on the upper part of the large cover, it is impossible to measure the actual temperature at the bottom of the heating furnace, making it impossible to control the bottom temperature. This leads to condensation of the material vapor at the bottom, clogging the channel heater. 2. In the initial stage of distillation, there is a large amount of unreacted material in the reactor. After distillation begins, it mixes with the airflow and accumulates at the bottom of the distillation channel, where it reacts to produce metallic titanium that adheres to the lower part of the distillation channel. Because its melting point is much higher than the heater temperature, it cannot evaporate through heating, thus affecting heat transfer and causing the temperature in the heating channel to further decrease, resulting in a continuous increase in condensate deposits. Summary of the Invention

[0004] The purpose of this invention is to provide an easy-to-clean sponge titanium distillation heating passage to solve the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved as follows: an easy-to-clean sponge titanium distillation heating passage, which includes a heating channel, a cleaning hammer rod is provided inside the heating channel, a large cover is provided at the bottom of the heating channel, a large cover base plate is fixedly provided at the bottom of the large cover, and a heating mechanism is provided on the lower side of the large cover base plate.

[0006] A first temperature-measuring thermocouple is fixedly installed at the lower part of the heating channel. The first temperature-measuring thermocouple is used to measure the temperature at the lower part of the heating channel.

[0007] A second temperature-measuring thermocouple is fixedly installed inside the heating mechanism. The second temperature-measuring thermocouple is used to measure the temperature of the heating mechanism.

[0008] A peeling section is provided inside the lower side of the heating channel.

[0009] The peeling section includes a fixing head, and an easy-pull tab is disposed between the fixing heads. The easy-pull tab has a multi-layer peeling structure.

[0010] Both ends of the pull tab are equipped with pull cords. The pull cords facilitate the release of the pull tab.

[0011] The pull tab is made of pure titanium and has a thickness of 0.2-0.3 mm.

[0012] The beneficial effects of this utility model are: Our organization has repositioned the original first temperature-measuring thermocouple to the lower part of the heating channel, enabling precise temperature measurement of easily condensing areas and better controlling the temperature in these areas to prevent material from condensing. A heating mechanism and a second temperature-measuring thermocouple have been added to the underside of the large cover plate at the bottom of the heating channel to prevent heat from diffusing from the heating channel to the large cover plate and causing low-temperature condensation.

[0013] Inside the heating channel, since the pull tabs cover the channel, the deposits only adhere to the pull tabs. When cleaning the deposits on the pull tabs, the cleaning hammer can easily push the condensate along with the pull tabs into the bottom of the cleaning channel, making the operation convenient.

[0014] Timely and thorough cleaning ensures that the heat transfer efficiency of the inner wall of the heating channel is always at its best, avoiding local overheating or underheating caused by uneven scale thickness. This helps to stabilize the distillation process and improve the uniformity and quality of sponge titanium products. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings. Example 1

[0020] like Figure 1-3As shown, an easy-to-clean sponge titanium distillation heating passage includes a heating channel 1, a cleaning hammer rod 3 is provided inside the heating channel 1, a large cover 2 is provided at the bottom of the heating channel 1, a large cover base plate 5 is fixedly provided at the bottom of the large cover 2, and a heating mechanism 6 is provided on the lower side of the large cover base plate 5.

[0021] Furthermore, a first temperature-measuring thermocouple 4 is fixedly installed at the lower part of the heating channel 1. The first temperature-measuring thermocouple 4 is used to measure the temperature at the lower part of the heating channel 1.

[0022] Furthermore, a second temperature-measuring thermocouple 7 is fixedly installed inside the heating mechanism 6. The second temperature-measuring thermocouple 7 is used to measure the temperature of the heating mechanism 6.

[0023] In use, this invention adjusts the position of the original first temperature-measuring thermocouple 4 to the lower part of the heating channel 1, enabling precise temperature measurement of easily condensing areas and better controlling the temperature of these areas to prevent material from condensing. A heating mechanism 6 and a second temperature-measuring thermocouple 7 are added to the underside of the large cover plate 5 at the bottom of the heating channel 1, and the temperature of this part is set 100-150°C higher than the bottom of the heating channel 1 to prevent heat from the heating channel 1 from diffusing to the large cover plate 5 and causing low-temperature condensation. Example 2

[0024] like Figure 1-3 As shown, an easy-to-clean sponge titanium distillation heating passage includes a heating channel 1, a cleaning hammer rod 3 is provided inside the heating channel 1, a large cover 2 is provided at the bottom of the heating channel 1, a large cover base plate 5 is fixedly provided at the bottom of the large cover 2, and a heating mechanism 6 is provided on the lower side of the large cover base plate 5.

[0025] Furthermore, a first temperature-measuring thermocouple 4 is fixedly installed at the lower part of the heating channel 1. The first temperature-measuring thermocouple 4 is used to measure the temperature at the lower part of the heating channel 1.

[0026] Furthermore, a second temperature-measuring thermocouple 7 is fixedly installed inside the heating mechanism 6. The second temperature-measuring thermocouple 7 is used to measure the temperature of the heating mechanism 6.

[0027] The configuration of the first temperature measuring thermocouple 4 located at the bottom of the heating channel 1 and the second temperature measuring thermocouple 7 located inside the heating mechanism 6 enables more precise temperature difference control and temperature monitoring.

[0028] Furthermore, a peeling section 8 is provided inside the lower side of the heating channel 1. The peeling section 8 can also effectively protect the inner wall of the heating channel 1, avoiding scratches or deformation caused by mechanical cleaning, thereby significantly extending the service life of the equipment and reducing the overall maintenance cost.

[0029] Furthermore, the peeling section 8 includes a fixing head 9, and an easy-pull tab 10 is disposed between the fixing heads 9. The easy-pull tab 10 has a multi-layer peeling structure.

[0030] Furthermore, both ends of the pull tab 10 are provided with pull cords 11. The pull cords 11 facilitate the release of the pull tab 10.

[0031] Furthermore, the pull tab 10 is made of pure titanium, and its thickness is 0.2-0.3 mm. Since the pull tab 10 is made of pure titanium, it will not contaminate the titanium sponge.

[0032] In another embodiment, further, a multi-layer structure of 0.2-0.3mm pure titanium easy-pull tabs 10 is added inside the heating channel 1. Since the easy-pull tabs 10 cover the inside of the heating channel 1, each layer of the easy-pull tabs 10 has an easy-pull string 11. When titanium and its condensate adhere to this location, the adhering matter only adheres to the easy-pull tabs 10. Because the easy-pull tabs 10 have easy-pull strings 11 and are relatively thin, the cleaning hammer can easily push the condensate along with the same layer of easy-pull tabs 10 into the bottom of the cleaning channel and into the reactor when cleaning the adhering matter on the easy-pull tabs 10. Moreover, since the easy-pull tabs 10 are made of pure titanium, they will not contaminate the sponge titanium. Traditional knocking cleaning generates a lot of dust and debris, which may contaminate the product or working environment. However, the easy-pull tabs 10 remove the adhering matter as a whole or in large pieces, making the cleaning process more controllable and cleaner.

[0033] Our organization has transformed the previously arduous, dangerous, and potentially damaging cleaning process into an efficient, safe, low-cost, and standardized operating procedure. This offers numerous advantages, including increased production efficiency, extended equipment lifespan, and improved product quality.
