Description

Technical Field

[0001] This utility model belongs to the technical field of sponge titanium heating furnace, specifically relating to a cleaning device for a sponge titanium distillation heating furnace. 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. Because the insulation screen of the cleaning device is connected to the ambient temperature area during sponge titanium production, the temperature of the insulation screen is lower than the condensation temperature of the evaporating material. During operation, a large amount of condensate will form in this area, causing the gap between the cleaning hammer and the insulation screen to become blocked and jammed, preventing the cleaning hammer from moving normally; 2. When condensate condenses in the gap of the insulation screen, the cleaning hammer of the cleaning device will tilt. However, because the connection between the cleaning hammer and the hydraulic cylinder only has one degree of freedom in one direction, and there are multiple possible directions of jamming, the hydraulic cylinder is in a non-vertical movement state for a long time. This makes the hydraulic cylinder seal prone to failure, resulting in oil leakage and entering the heating channel, which contaminates the sponge titanium. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning device for a sponge titanium distillation heating furnace, in order to solve the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved as follows: a cleaning device for a sponge titanium distillation heating furnace, comprising a cleaning hammer rod located inside a heating channel, a rod body fixedly mounted above the cleaning hammer rod, a heat preservation screen disposed inside the upper side of the heating channel, the rod body penetrating the heat preservation screen, a heating component disposed inside the heat preservation screen, a driving component disposed above the heating channel, and the output end of the driving component being connected to the upper end of the rod body via a universal joint.

[0006] A sealing part is fixedly installed between the rod body and the heating channel. The sealing part can effectively isolate external air, prevent external air from entering the heating channel, ensure that the internal vacuum is not broken, and improve product quality.

[0007] The sealing part is equipped with a sealing packing. It has good high temperature resistance and is easy to replace after wear, resulting in low maintenance costs.

[0008] The heating element is a heating resistance wire.

[0009] The insulation screen is equipped with a temperature-sensing thermocouple. The thermocouple can monitor the temperature of the heating area in real time and is linked with the temperature control system to ensure accurate and stable process temperature.

[0010] The drive component is an electric cylinder, which avoids the hydraulic oil leakage problem of the original hydraulic cylinder.

[0011] The universal joint includes a housing and a universal ball joint.

[0012] The beneficial effects of this utility model are: The addition of a heating device inside the insulation screen reduces heat loss from the heating channel, prevents condensation of evaporating substances in this area from causing the inner cavity to become stuck, and ensures the normal operation of the cleaning device.

[0013] The original hydraulic cylinder drive was replaced with an electric cylinder drive, avoiding the hydraulic oil leakage problem of the original hydraulic cylinder. The output end of the electric cylinder is connected to the cleaning hammer rod through a specially designed universal joint, which prevents the cleaning hammer rod from getting stuck in any direction.

[0014] During operation, there may be slight concentricity deviations between the drive components and the rod. The universal joint structure can flexibly adapt to these deviations, avoiding the formation of additional bending moments and stresses, and protecting the rod and sealing components from damage.

[0020] The present invention will be further described below with reference to the accompanying drawings. Example 1

[0021] like Figure 1-4 As shown, a cleaning device for a sponge titanium distillation heating furnace includes a cleaning hammer rod 2 located inside a heating channel 1. A rod body 8 is fixedly installed above the cleaning hammer rod 2. A heat preservation screen 7 is installed inside the upper side of the heating channel 1. The rod body 8 passes through the heat preservation screen 7. A heating component 12 is installed inside the heat preservation screen 7. A driving component 3 is installed above the heating channel 1. The output end of the driving component 3 is connected to the upper end of the rod body 8 via a universal joint 4.

[0022] For better results, a sealing part 5 is fixedly provided between the rod body 8 and the heating channel 1. This ensures the sealing of the heating channel and prevents heat loss and the entry of external impurities.

[0023] For better performance, a sealing packing 6 is provided inside the sealing part 5. It has good high temperature resistance, is easy to replace after wear, and has low maintenance costs.

[0024] In use, this utility model utilizes the heating component 12 inside the heat preservation screen 7 to heat the heat preservation screen 7. The temperature inside the heat preservation screen 7 is monitored in real time by the temperature measuring thermocouple 11. The working state of the heating resistance wire is adjusted according to production needs to maintain a suitable temperature environment inside the heating channel 1 and ensure the normal operation of the sponge titanium distillation process.

[0025] A heating element 12 and a temperature-measuring thermocouple 11 sensor are added inside the heat preservation screen 7 to control the temperature of this area to always be 100-150℃ higher than the temperature inside the heating channel 1, preventing heat from spreading to the outside and causing condensation of evaporating substances, thus avoiding the phenomenon of the cleaning hammer rod 2 getting stuck. Example 2

[0026] like Figure 1-4 As shown, a cleaning device for a sponge titanium distillation heating furnace includes a cleaning hammer rod 2 located inside a heating channel 1. A rod body 8 is fixedly installed above the cleaning hammer rod 2. A heat preservation screen 7 is installed inside the upper side of the heating channel 1. The rod body 8 passes through the heat preservation screen 7. A heating component 12 is installed inside the heat preservation screen 7. A driving component 3 is installed above the heating channel 1. The output end of the driving component 3 is connected to the upper end of the rod body 8 via a universal joint 4.

[0027] For better results, a sealing part 5 is fixedly provided between the rod body 8 and the heating channel 1. This ensures the sealing of the heating channel and prevents heat loss and the entry of external impurities.

[0028] For better performance, a sealing packing 6 is provided inside the sealing part 5. It has good high temperature resistance, is easy to replace after wear, and has low maintenance costs.

[0029] For better results, the heating element 12 is a heating resistance wire. This provides a stable heating effect for the heat preservation screen 7.

[0030] For better results, a temperature-sensing thermocouple 11 is installed inside the insulation screen 7. The temperature-sensing thermocouple 11 can monitor the temperature of the heating area in real time and is linked with the temperature control system to ensure accurate and stable process temperature.

[0031] For better performance, the drive component 3 is an electric cylinder. This avoids the hydraulic oil leakage problem of the original hydraulic cylinder.

[0032] For better performance, the universal joint 4 includes a housing 9 and a universal ball joint 10.

[0033] In another embodiment, when the inner wall of the heating channel 1 needs cleaning, the drive component 3 is activated. The output end of the drive component 3 drives the rod 8 to move via the universal joint 4. Since the cleaning hammer rod 2 is fixed below the rod 8 and located inside the heating channel 1, the movement of the rod 8 drives the cleaning hammer rod 2 to move within the heating channel 1, performing cleaning actions such as tapping and scraping on the inner wall of the heating channel 1 to remove impurities and other debris adhering to the inner wall. The universal joint 4 ensures effective transmission between the output end of the drive component 3 and the rod 8 at different angles.

[0034] In drive component 3, the hydraulic cylinder is replaced with an electric cylinder, directly eliminating oil leakage from the hydraulic cylinder at its source and preventing sponge titanium contamination caused by leakage. The connection between rod 8 and electric cylinder is changed to a universal joint 4 to avoid jamming of the cleaning hammer rod due to non-directional tilting during the movement of the electric cylinder, which would lead to damage to the cleaning hammer rod and electric cylinder.
