Description

Technical Field

[0001] This utility model relates to the technical field of cleaning molten salt slag from salt bath furnaces, and in particular to a device for rapidly cleaning molten salt slag from salt bath furnaces. Background Technology

[0002] Molten salt slag is a solid waste generated during the high-temperature treatment of salt solutions in a salt bath furnace. This slag mainly consists of salts, oxides, and sulfides, and may contain harmful substances such as heavy metals. The generation of molten salt slag not only pollutes the environment but also poses a threat to workers' health.

[0003] In the existing technology, when cleaning the waste residue inside the salt bath furnace, the salt bath furnace must first be stopped, and then the molten salt inside is taken out after the salt bath furnace reaches normal temperature. Then, the molten salt waste residue can be removed with professional tools. However, when cleaning the waste residue, it is necessary to wait for the temperature to drop and also to shut down the salt bath furnace. Therefore, cleaning the molten salt waste residue takes a lot of time, which reduces the working efficiency of the salt bath furnace and affects the quenching operation of the salt bath furnace. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for quickly cleaning molten salt slag from a salt bath furnace, so as to solve the technical problems mentioned in the background art.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. This device for quickly cleaning molten salt slag from a salt bath furnace can quickly transfer molten salt from a working furnace to another furnace. The furnace receiving the molten salt can continue quenching, while the furnace outputting the molten salt can be directly cooled and the molten salt slag can be cleaned. This achieves the effect of avoiding the salt bath furnace stopping and affecting the quenching progress when cleaning molten salt slag from the salt bath furnace.

[0014] 2. The device for quickly cleaning molten salt slag from a salt bath furnace includes positioning clamps for fixing the conveying pipe.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0022] Reference Figures 1-3 This utility model discloses a device for quickly cleaning molten salt slag from a salt bath furnace, comprising a base 1, two furnace bodies 2 arranged above the base 1, two hydraulic expansion joints 3 connected to the bottom sides of each of the two furnace bodies 2, the bottom ends of the hydraulic expansion joints 3 being fixedly connected to the base 1, a hydraulic pipe 4 connecting the bottoms of two adjacent hydraulic expansion joints 3, two hydraulic cylinders 5 installed on the top side of the base 1, the output ends of the two hydraulic cylinders 5 being respectively connected to the adjacent hydraulic expansion joints 3, and a conveying component 6 arranged in the middle of the top side of the base 1.

[0023] In this embodiment, during use, one of the furnace bodies 2 can be used for quenching. After a certain period of use, two hydraulic cylinders 5 can be activated simultaneously to retract the hydraulic expansion joints 3. The two adjacent hydraulic expansion joints 3 are connected by hydraulic pipes 4. Therefore, when one hydraulic expansion joint 3 reduces the hydraulic oil, the two hydraulic expansion joints 3 connected by hydraulic pipes 4 will retract synchronously to maintain pressure balance. When the hydraulic expansion joints 3 retract, the two furnace bodies 2 are connected by the set conveyor 6. At the same time, the molten salt in the furnace body 2 being used is transported to the unused furnace body 2 through the conveyor 6. At this time, the furnace body 2 containing molten salt slag is cooled. At the same time, the hydraulic expansion joints 3 are controlled to extend, closing the connection between the two furnace bodies 2. After the other furnace body 2 is fed with molten salt, it can continue to carry out quenching. After the temperature of the furnace body 2 containing molten salt slag has cooled down, it can be cleaned, thereby avoiding affecting the progress of the quenching work.

[0024] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the conveying component 6 includes a positioning clamp 7, which is fixedly installed in the middle of the top side of the base 1. A conveying pipe 8 is fixedly installed inside the clamp, and both ends of the conveying pipe 8 are connected to the corresponding furnace body 2 through a switch component 9.

[0025] In this embodiment, the positioning clamp 7 is used to fix the conveying pipe 8. Multiple positioning clamps 7 can be set to position the conveying pipe 8 during use. The number of positioning clamps 7 can be adjusted according to the length of the conveying pipe 8. The conveying pipe 8 is used to connect the two furnace bodies 2, so as to facilitate the conveying of molten salt after connecting the two furnace bodies 2. The switch 9 is used to control the connection status between the furnace body 2 and the conveying pipe 8.

[0026] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the switch 9 includes a circular groove 10, which is formed in the middle of the bottom side of the furnace body 2. A positioning piece 11 is slidably installed in the circular groove 10. A connecting pipe 12 is fixedly connected to the bottom side of the positioning piece 11. A conveying groove 13 is formed on the top side of the outer peripheral wall of the connecting pipe 12.

[0027] In this embodiment, the circular groove 10 and the connecting pipe 12 are configured such that the circular groove 10 is used to install the positioning piece 11, and the positioning piece 11 is used to seal the circular groove 10 to prevent the molten salt inside the furnace body 2 from leaking during operation. The connecting pipe 12 has a conveying groove 13 positioned on its outer peripheral wall. When the bottom end of the connecting pipe 12 is pushed against and moves upward, the positioning piece 11 will release the seal on the circular groove 10, and the molten salt will enter the connecting pipe 12 along the conveying groove 13, thereby achieving the conveying effect.

[0028] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the bottom end of the connecting pipe 12 extends into the conveying pipe 8. A limiting ring 14 is provided in the conveying pipe 8 at the bottom end of the connecting pipe 12. The outer peripheral wall of the limiting ring 14 is fixedly connected to the inner side wall of the conveying pipe 8. The top side of the limiting ring 14 is attached to the bottom end of the connecting pipe 12. A driving member 15 is provided on the top side of the base 1.

[0029] In this embodiment, the bottom end of the connecting pipe 12 extends into the conveying pipe 8, and the conveying pipe 8 is released from the limiting ring 14. Therefore, when the hydraulic cylinder 5 controls the hydraulic telescopic joint 3 to retract, the furnace body 2 will move downward. The connecting pipe 12 is limited by the limiting ring 14 and cannot move downward. The positioning piece 11 connected to the top of the connecting pipe 12 will disengage from the circular groove 10 due to the downward movement of the furnace body 2, so that the conveying groove 13 is connected to the furnace body 2. At this time, the molten salt will enter the conveying groove 13 and then flow into the conveying pipe 8, and thus be conveyed to another furnace body 2 through the conveying pipe 8. After the conveying is completed, the hydraulic cylinder 5 drives the hydraulic telescopic joint 3 to extend. At this time, the furnace body 2 moves upward, and the positioning piece 11 will return to the circular groove 10 due to gravity. When the positioning piece 11 disengages from the circular groove 10, a filter screen is provided on the outer peripheral wall of the positioning piece 11, and the filter screen is slidably connected to the outer peripheral wall of the positioning piece 11. The bottom end of the filter screen is fixedly connected to the inner bottom side of the furnace body 2 to prevent molten salt slag from entering the conveying pipe 8.

[0030] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the driving component 15 includes a driving motor 16, the output end of the driving motor 16 is connected to an output shaft 17, the output shaft 17 extends into the conveying pipe 8, and a spiral blade 18 is fixedly installed on the outer peripheral wall of the output shaft 17.

[0031] In this embodiment, the drive motor 16 drives the output shaft 17 to rotate, and the output shaft 17 will drive the spiral blade 18 to rotate. The rotation of the spiral blade 18 will transport the molten salt discharged from one furnace body 2 to another furnace body 2, so as to avoid the presence of residue in the conveying pipe 8, which would affect the quenching work.

[0032] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, there is a gap between the end of the conveying pipe 8 and the corresponding bottom side of the furnace body 2, and the side of the spiral blade 18 is in contact with the inner wall of the conveying pipe 8.

[0033] In this embodiment, air is left at the ends of the furnace body 2 and the bottom conveying pipe 8 to prevent the connecting pipe 12 from sinking too far into the furnace body 2, which would cause the positioning plate 11 to move upward too far, making it easy for molten salt slag to enter the conveying pipe 8. The outer side of the spiral blade 18 is attached to the inner side wall of the conveying pipe 8 to ensure that the molten salt liquid is transported completely, and to prevent the molten salt liquid from remaining in the conveying pipe 8.

[0034] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
