Description

Technical Field

[0001] The utility model relates to the field of submerged arc furnace equipment, in particular to a two-dimensional tamping manipulator for a submerged arc furnace. Background Art

[0002] The tamping is a process in the smelting process of the ore-fired furnace, a major part of the production process of the ore-fired furnace, and a necessary condition for the recovery of the furnace condition. The tamping tool used for tamping is used to make the charge in the furnace uniform, expand the reaction zone, eliminate suspended materials, crush the slag, and reduce crusting and flame spraying on the charge surface. At present, the tamping car is a commonly used tamping tool. The tamping car has a tamping arm, and a tamping rod is installed at the end of the tamping arm. The tamping arm is extended into the ore-fired furnace, and the charge is distributed by stirring the tamping rod located in the furnace.

[0003] The working temperature in the submerged arc furnace is usually as high as more than 1,000 degrees. The tamping arm drives the tamping rod to stir, and the tamping rod will shake, which will inevitably affect the sealing of the submerged arc furnace, causing gaps between the inside and outside of the submerged arc furnace, affecting the environment inside the submerged arc furnace. In addition, the tamping arm needs to be made of high-temperature resistant material, otherwise it will easily cause damage after multiple tampings, reducing its service life. Utility Model Content

[0004] In order to solve the problems in the prior art that the tamping tool affects the sealing of the submerged arc furnace and the service life is affected by high temperature, the utility model proposes a two-dimensional tamping manipulator for the submerged arc furnace.

A sealing cover is provided above the furnace tower of the ore-heating furnace, comprising a tamping arm, a tamping claw, a water seal sleeve and a driving member. The tamping claw is fixed to the bottom end of the tamping arm and is located in the ore-heating furnace. The tamping arm passes through the sealing cover and extends out of the ore-heating furnace. The water seal sleeve is fixed to the sealing cover and connected to the tamping arm. The top end of the tamping arm is fixed to the driving member, and the driving member is fixed to a supporting frame.

[0007] Preferably, a long cavity is provided inside the tamping arm, which extends from the top of the tamping arm to the tamping arm inside the tamping furnace and has a preset distance from the bottom of the tamping arm.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Figure 1 and Figure 3 The two-dimensional tamping robot for an electric arc furnace shown in the figure has a sealing cover 1 above the furnace tower of the electric arc furnace, including: a tamping arm 2, a tamping claw 3, a water seal sleeve 4 and a driving member 5. The tamping claw 3 is fixed to the bottom end of the tamping arm 2 and is located in the electric arc furnace. The tamping arm 2 extends out of the electric arc furnace through the sealing cover 1. The water seal sleeve 4 is fixed on the sealing cover 1 and connected to the tamping arm 2. The top end of the tamping arm 2 is fixed on the driving member 5, and the driving member 5 is fixed on the supporting frame.

[0021] The utility model discloses a two-dimensional furnace tamping manipulator for an ore-heating furnace, which is used on a closed ore-heating furnace. The furnace tamping arm is driven by a driving member to stir in the ore-heating furnace. When the furnace tamping arm moves up and down, the inside and outside of the ore-heating furnace are isolated by a water seal sleeve, and the water seal sleeve can play a role in cooling, thereby extending the service life.

A cooling pipe 6 is provided in the long cavity 21, and a water inlet and a water outlet are provided at the top of the cooling pipe 6. The water inlet is used to flow in cooling water, and the water outlet is used to return water, which can directly cool the furnace tamping rod and be used in combination with the water seal sleeve to cool the inside and outside of the furnace tamping rod at the same time, thereby accelerating the cooling efficiency and further greatly improving the service life of the furnace tamping rod. The long cavity of the furnace tamping rod does not reach its bottom end, and the part of the furnace tamping rod without the long cavity is a solid rod body, which ensures the strength of the furnace tamping rod. The preset distance between the long cavity and the bottom of the furnace tamping arm can be adjusted according to the size of the furnace body.

[0023] like Figure 1 and Figure 2As shown, the water seal sleeve 4 includes a relatively inverted cylindrical sleeve 41 and an annular sleeve 42, the outer wall of the annular sleeve 42 is higher than the inner wall, the cylindrical sleeve 41 is located inside the annular sleeve 42, the bottom end of the annular sleeve 41 is fixed to the top of the sealing cover 1, the cylindrical sleeve 41 is fixed on the tamping arm 2 outside the submerged arc furnace, and static pressure water is arranged inside the annular sleeve 42 to isolate the inside and outside of the submerged arc furnace. In the water seal sleeve of the utility model, the cylindrical sleeve moves with the tamping rod, and there is static pressure water between the cylindrical sleeve and the annular sleeve to form a water seal, which completely isolates the inside and outside of the submerged arc furnace. Even if the tamping rod swings back and forth, the cylindrical sleeve swings with the tamping rod, which does not affect the sealing of the water seal sleeve, thereby solving the problem of the tamping rod swinging in a high temperature environment in the prior art causing the sealing between the tamping rod and the submerged arc furnace to be poor.

[0024] like Figure 2 As shown, the outer top end of the circular sleeve 42 is provided with an extension section, and the inner side of the extension section is provided with a female thread 43; the upper part of the furnace tamping arm 2 is provided with a male thread 22 for threaded connection with the female thread 43, so that the furnace tamping arm can be spirally inserted vertically into the ore-fired furnace for tamping operation, and at the same time, the furnace tamping arm and the circular sleeve are closely matched.

[0025] like Figure 1 As shown, a heat insulating layer 7 is provided on the inner side of the sealing cover passing through the ramming arm to strengthen the heat preservation in the submerged arc furnace.

[0026] When in use, the tamping furnace claw is fixed at the bottom end of the tamping furnace arm and is located in the mineral arc furnace, the cooling pipe is arranged in the long cavity of the tamping furnace arm, cooling water is arranged in the cooling pipe, the tamping furnace arm is connected to the cylindrical sleeve of the water seal sleeve, the male thread of the tamping furnace arm is threadedly connected with the female thread of the circular ring sleeve extension section of the water seal sleeve, the bottom end of the water seal sleeve is connected with the sealing cover, static pressure water is arranged in the water seal sleeve, the top end of the tamping furnace arm is connected with the driving member, the driving member is fixed on the supporting frame, the driving member drives the tamping furnace arm to spirally rise or descend along the male thread thereon and the female thread of the circular ring sleeve extension section of the water seal sleeve, the tamping furnace arm drives the tamping furnace claw to spirally rise or descend in the mineral arc furnace, so as to realize the spiral vertical insertion for tamping furnace operation.
