Description

Technical Field

[0001] The utility model relates to the technical field of feeding nozzles, in particular to a connecting rod of a full-automatic feeding nozzle. Background Art

[0002] As one of the key equipment components of the submerged arc furnace, the fully automatic feeding nozzle has a hydraulic drive part installed on the top of the submerged arc furnace cover, and the discharge nozzle part is located inside the furnace chamber of the submerged arc furnace. The rotation and prying movement of the fully automatic feeding nozzle are driven by two cylinders along the horizontal and vertical directions to drive the connected components respectively; in the horizontal direction, the tail of the cylinder barrel is welded and fixed to the top of the cover plate, and the end of the piston rod is welded and fixed to the rotating cylinder with a seven-shaped head. The cylinder piston rod drives the rotating cylinder to rotate around the center throat, thereby realizing the rotation and distribution of the feeding nozzle; in the vertical direction, the cylinder drives the connecting rod to realize vertical movement, and the connecting rod then transmits the movement to the feeding nozzle through the pin shaft, thereby realizing the prying and distribution of the feeding nozzle; thereby, the charge is evenly arranged in the furnace chamber of the submerged arc furnace, thereby completing the distribution operation.

[0003] The current installation method of the feeding nozzle is that the cylinder drive part is on the cover plate, and the discharge nozzle part is inside the furnace. Since the inside of the furnace is the raw material smelting reaction zone of the electric arc furnace, the connecting rod connected by the cylinder is in a high temperature environment for a long time. When subjected to alternating loads, it is more likely to bend and plastically deform, resulting in frequent failures, deformations, and fractures of the connecting rod, causing the fully automatic feeding nozzle to fail and become unusable, seriously restricting production.

[0004] Therefore, it is urgent to provide a connecting rod of a fully automatic feeding nozzle, which can cool the connecting rod during use compared to the prior art. Utility Model Content

[0005] The utility model solves the technical problems existing in the prior art and provides a connecting rod of a full-automatic feeding nozzle.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0007] A connecting rod for a fully automatic feeding nozzle comprises a connecting rod body, a first connecting ring, a second connecting ring, a water inlet pipe and a water outlet pipe, wherein one end of the connecting rod body is connected to the first connecting ring, and the other end of the connecting rod body is connected to the second connecting ring; a water inlet channel and a water outlet channel are provided inside the connecting rod body; the water inlet pipe and the water outlet pipe are connected to the outside of the connecting rod body; one end of the water inlet channel is connected to the water inlet pipe, and the other end of the water inlet channel is connected to the water outlet channel; and the water outlet channel is connected to the water outlet pipe at an end away from the water inlet channel.

[0008] Furthermore, the water inlet pipe includes a first pipe and a second pipe, the water outlet pipe includes a third pipe, the first pipe and the third pipe are connected to the connecting rod body, the end of the first pipe away from the connecting rod body is connected to the second pipe, and a set angle is set between the axis of the second pipe and the axis of the first pipe.

[0009] Furthermore, the first pipe and the third pipe are rotatably connected to the connecting rod body.

[0010] Furthermore, the first pipe is arranged obliquely to the upper wall of the connecting rod body, and the third pipe is arranged obliquely to the upper wall of the connecting rod body.

[0011] Furthermore, the third pipe is connected to a fourth pipe at one end away from the connecting rod body, and a set angle is set between the axis of the fourth pipe and the axis of the third pipe.

[0012] Furthermore, two first connecting rings are provided, and the two first connecting rings are respectively fixedly connected to both sides of one end of the connecting rod body, and the first pipe and the third pipe are located between the two first connecting rings.

[0013] Furthermore, the first connecting ring is provided with a first mounting hole.

[0014] Furthermore, a second mounting hole is formed through the second connecting ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model is connected to the oil cylinder and the feeding nozzle respectively through the first connecting ring and the second connecting ring. When the oil cylinder drives the feeding nozzle to move in the vertical direction, the water inlet pipe of the circulating water distributor of the electric arc furnace is connected with the water inlet pipe. At the same time, the return pipe of the circulating water distributor of the electric arc furnace is sleeved on the water outlet pipe, and circulating water is injected into the interior of the connecting rod body to cool the connecting rod body, thereby preventing the connecting rod from being subjected to alternating loads in a high-temperature environment and being more susceptible to bending and plastic deformation, thereby avoiding frequent failures, deformation and breakage of the connecting rod, ensuring that the automatic feeding nozzle can be used normally, and ensuring normal production.
