Description
Technical Field
[0001] The utility model relates to the technical field of burn-through device equipment, in particular to a burn-through device fixture for a full-automatic furnace unloading machine. Background Art
[0002] A burner is a special device that uses an electric arc to burn open the taphole in a submerged arc reduction furnace for producing ferroalloys. The principle is to use a transformer to generate a large current, generate an arc between the electrode and the taphole, and use the high temperature of the arc to burn the taphole open. During the specific operation, the worker holds the handle to bring the front end of the burner close to the taphole, and the carbon rod electrode generates an arc at the taphole, using the high temperature of the arc to burn open the taphole. The front end of the burner is often connected to a clamping head to clamp a carbon rod electrode. At present, bolts are often used to fix the carbon rod at the clamping head, but this method requires a large number of bolts, and when replacing carbon rods of different sizes, all the bolts need to be removed and reinstalled, which is difficult to adapt to carbon rods of different sizes. The carbon rod is prone to shaking during use, resulting in large losses and high costs. Utility Model Content

The main frame 1 can connect the limit unit 2 and the fixing unit into a whole, thereby increasing the overall stability. The specific structure of the burner fixture (the above-mentioned fully automatic furnace discharge machine burner fixture) is described below.
[0024] In this embodiment, the main frame 1 includes two vertical fixing plates 11 arranged opposite to each other, and a rectangular base is connected at the lower end between the two fixing plates 11. The base can not only increase the overall stability, but also support the carbon rod 4.
[0025] In this embodiment, the limiting unit 2 includes two limiting rods 21 arranged in parallel on both sides of the lower part of the main frame 1. The two limiting rods 21 can clamp both sides of the carbon rod 4 to prevent left and right movement.
[0026] Preferably, the two limiting rods 21 are respectively welded to the two fixing plates 11 , and both limiting rods 21 are welded to the base, so as to increase the stability of the limiting rods 21 .
[0027] In this embodiment, the clamping unit 3 includes a limit block 33 vertically slidably arranged above the two limit rods 21, and a first wedge block 31 and a second wedge block 32 which are relatively arranged above the limit block 33 and are respectively connected to the main frame 1 and the limit block 33; the limit block 33 can be fixed on the upper side of the carbon rod 4, and the limit block 33 can be clamped by the interaction of the two wedge blocks to prevent the carbon rod 4 from moving up and down.
[0028] Furthermore, vertical slide rails are provided on opposite sides of the two fixing plates 11, and sliders slidably connected to the slide rails are provided on both sides of the limit block 33. The limit block 33 can slide up and down through the cooperation of the slide rails and the sliders, which can adapt to carbon rods 4 of different sizes.
[0029] As a preferred embodiment, the upper end of the limit block 33 is set as a rectangular surface perpendicular to the fixed plate 11, and the lower end is provided with an arc-shaped groove, which passes through the front and back along the direction of the limit rod 21, and the groove opening is set downward, which can increase the contact area between the limit block 33 and the clamped carbon rod 4 and increase the force-bearing surface.
[0030] Further preferably, the groove is arc-shaped, and the distance between the center of the groove and the two limit rods 21 is the same, which can ensure that the carbon rod 4 is located at the center of the two limit rods 21 and the limit block 33, thereby improving the uniformity of the force on the carbon rod 4.
[0031] Preferably, the opening width of the groove of the limiting block 33 is not less than the distance between the two limiting rods 21, so as to ensure that the groove can match the carbon rods 4 of different sizes.
[0032] Parallel inclined surfaces are provided on opposite sides of the two wedge blocks (the first wedge block 31 and the second wedge block 32), wherein the first wedge block 31 is slidably connected to the main frame 1, and / or the second wedge block 32 is slidably connected to the limit block 33, and the sliding direction of the first wedge block 31 and / or the second wedge block 32 is not parallel to the inclined surface, one of the two wedge blocks can be fixed to the main frame 1 or the limit block 33, and the other can slide relatively, and during the sliding process, the two parallel inclined surfaces continue to approach each other until they are pressed against each other.
[0033] As a preferred embodiment, the second wedge block 32 is configured to be able to slide along the axial direction of the limiting rod 21, so that when the wedge block and the limiting block 33 are pressed against each other, the force for clamping the carbon rod downward always acts in the axial direction of the carbon rod 4.
[0034] In this embodiment, the cross-sections of the first wedge block 31 and the second wedge block 32 are both right-angled trapezoids. The first wedge block 31 is fixedly connected to the main frame with its inclined surface facing downward, and the second wedge block 32 is configured to be slidably connected to the limit block 33 with its inclined surface facing upward.
[0035] Specifically, the front end of the carbon rod 4 can pass through the burner fixture and enter the combustion furnace. The inclined surface of the first wedge block 31 is set so that the side away from the front end of the carbon rod 4 is higher than the side close to the front end of the carbon rod 4, and the inclined surface of the second wedge block 32 is set so that the side away from the front end of the carbon rod 4 is lower than the side close to the front end of the carbon rod 4.
[0036] In this embodiment, the main frame 1, the limiting rod unit 2 and the abutting unit 3 are made of Q235 steel, and the welds at the welding parts are smooth and free of burrs.
[0037] Through the above design, the utility model is a fully automatic furnace discharge machine burn-through fixture, which can fix the carbon rod 4 between the limit block 33 and the limit rod 21, and the limit rods 21 on both sides of the carbon rod 4 can prevent the carbon rod 4 from moving left and right, and at the same time, the limit block 33 above the carbon rod 4 can fix the carbon rod 4 to prevent it from moving up and down under the action of the first wedge block 31 and the second wedge block 32. The sliding of the limit block 33 and the columnar design of the limit rod 21 can adapt to carbon rods 4 of different sizes, and the contact surface with the carbon rod 4 is an arc surface, which can reduce the friction loss of the carbon rod 4.
