Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a furnace eye opening device for a silicon-aluminum alloy smelting furnace. Background Art

[0002] At present, the smelting furnace used for silicon aluminum alloy is mainly an electric arc furnace. There are openings on the furnace wall to guide the metal slag or metal melt in the furnace to flow out. During the smelting process, these openings are sealed with high-temperature resistant mud. After a smelting process is completed, it is necessary to use wooden stakes to support the sealing mud, and use a sledgehammer to manually knock the opening at the other end. During the operation, the wooden stakes need to be aligned and stabilized by the operator. The distance between the operator and the smelting furnace is relatively close, which is prone to danger, and the manual knocking method is more laborious.

[0003] Existing hydraulic mechanical eye-opening equipment is usually large in size and requires the installation of auxiliary facilities such as tracks on site. It is suitable for use in larger smelting furnaces, but the cost of modifying smelting furnaces with smaller on-site space is high. Utility Model Content

[0008] Furthermore, a counterweight block is fixedly provided at the tail of the hammer.

[0009] Furthermore, a guide ring is provided on the longitudinal beam and below the first guide wheel, and the traction rope is placed in the guide ring.

[0010] The utility model has the advantages that a swing arm and a hammer are swingably arranged under the door-type frame, and the hammer is used to strike the sealing mud at the furnace eye position instead of the traditional manual knocking method, so that the operator is farther away from the furnace eye, thereby improving the safety of the eye opening operation; at the same time, a lifting device is also provided, so that the operator can operate on both sides of the door-type frame to avoid the swinging area of ​​the hammer, and the pendulum can be prevented from rebounding and injuring people; further, an alignment device is also provided to facilitate alignment with the furnace eye position, so that the impact position of the hammer is more accurate.

[0017] like Figure 1As shown: a furnace eye opening device for a silicon-aluminum alloy smelting furnace, comprising a door-shaped frame 1, a striker 2, a swing arm 3 and a lifting device 4, a longitudinal beam 102 is fixedly arranged in the middle of a crossbeam 101 of the door-shaped frame 1, two swing arms 3 are hinged below the longitudinal beam 102, the two swing arms 3 are arranged in parallel, the lower ends of the swing arms 3 are respectively hinged to the striker 2, the striker 2 is arranged parallel to the longitudinal beam 102, the longitudinal beam 102, the two swing arms 3 and the striker 2 form a parallelogram connecting rod structure, the striker 2 can swing freely parallel to the longitudinal beam 102, and the striker 2 can swing freely parallel to the longitudinal beam 102. A counterweight block 6 is fixed at the tail, which is used to increase the weight of the hammer 2 and enhance the kinetic energy of the hammer 2 during impact. The head of the hammer 2 is made of high-strength alloy steel, has good wear resistance and impact resistance, and can withstand multiple impacts without deformation. Its working principle is that when it is necessary to open an eye, the hammer 2 is lifted to a certain height and then released freely. The gravitational potential energy of the hammer 2 is converted into kinetic energy to hit the opening on the furnace wall, replacing the traditional method of manually hammering wooden stakes to open holes. The operator is relatively far away from the position of the smelting furnace eye.

[0018] like Figure 2 As shown: the lifting device 4 includes a traction rope 401, a first guide wheel 402 and a second guide wheel 403. The first guide wheel 402 is rotatably provided at one end of the tail of the hammer 2 on the longitudinal beam 102, and a support arm 103 is provided at one end of the cross beam 101 parallel to the longitudinal beam 102. The second guide wheel 403 is rotatably provided at the free end of the support arm 103. One end of the traction rope 401 is fixed to the position where the hammer 2 is hinged with the swing arm 3 near the tail of the hammer, and the other end of the traction rope 401 passes through the first guide wheel 402 and the second guide wheel 403 in turn and is vertically downwardly placed on one side of the door frame 1. The operator can pull the traction rope 401 downward, and the traction rope 401 pulls up the upper rear side of the tail of the hammer 2, and then releases the traction rope 401 to make the hammer 2 fall freely; 2, a guide ring 404 is provided below the first guide wheel 402, and the traction rope 401 is placed in the guide ring 404. When the hammer 2 naturally droops, the swing arm 3 is in a vertical state. At this time, the fixed point of one end of the traction rope 401 is located at the hinge position of the swing arm 3 on the hammer 2. When the traction rope 401 is pulled backward, the force direction should be obliquely upward to the rear side. Therefore, the first guide wheel 402 is placed above the rear side of the hammer. When pulling, the traction rope 401 has a certain angle with the groove of the first guide wheel 402 due to the force direction. Therefore, in order to prevent the traction rope 401 from slipping out of the groove of the first guide wheel 402, a guide ring 404 is provided below the first guide wheel 402. The guide ring 404 can turn the traction rope 401 from other angles to a vertical angle to prevent the traction rope 401 from slipping out of the first guide wheel 402.

[0019] like Figure 3As shown: since it is difficult to judge the point where the hammer 2 swings and strikes, in order to facilitate the landing point of the hammer 2 to be aligned with the furnace eye on the furnace wall, an alignment device 5 is also provided, and the alignment device 5 includes a vertical alignment mechanism and a horizontal alignment mechanism. A vertical alignment mechanism is respectively installed at both ends of the crossbeam 101 of the door-type frame 1, and a horizontal alignment mechanism is installed on one of the columns of the door-type frame 1; the vertical alignment mechanism and the horizontal alignment mechanism include a mounting seat 501, a rotating part 502 and a straight-line laser 503, and the rotating part 502 is hingedly installed on the mounting seat 501, and the rotating part 502 is tightly matched with the mounting seat 501. The laser emission direction of the straight-line laser 503 can be adjusted by adjusting the angle of the rotating part 502, and the straight-line laser 503 is fixedly installed in the rotating part 502, wherein the indicator lines emitted by the two straight-line lasers 503 of the vertical alignment mechanism are projected onto the furnace wall as two vertical indicator lines, and the indicator lines emitted by the straight-line laser 503 of the horizontal alignment mechanism are projected onto the furnace wall as two vertical indicator lines. It is a horizontal indicator line. The rotating part 502 of the vertical alignment mechanism can swing and adjust the direction along the horizontal plane, and the rotating part 502 of the horizontal alignment mechanism can swing and adjust the direction along the vertical plane. Before use, select a wall as a reference, and adjust the indicating position of the alignment device 5 to coincide with the actual landing point of the hammer 2: place the door-shaped frame 1 in front of the reference wall, so that the hammer 2 is pushed up to a height of about 10 cm above the front side until the top of the hammer 2 touches the wall, mark the position where the hammer 2 contacts at this time, and this position is the best impact point of the hammer 2, then put down the hammer 2 and let it droop naturally, adjust the rotating part 502 of the vertical alignment mechanism so that the indicator line emitted by the two vertical alignment mechanisms' straight line lasers 503 passes through the midpoint of the impact point 2 of the hammer 2, and make the two vertical indicator lines coincide, and then adjust the rotating part 502 of the horizontal alignment mechanism so that the indicator line it emits coincides with the midpoint of the impact point of the hammer 2. At this time, the indicator point where the indicator lines on the wall intersect with the impact point of the hammer 2 has completed the calibration.

[0020] When it is necessary to open a furnace eye, the entire device of the utility model is placed in front of the furnace wall to be opened, the door frame 1 is manually moved, and the distance from the door frame 1 to the furnace wall is adjusted so that the indicator lines emitted by the two vertical alignment mechanisms coincide with each other. At this time, the calibration of the horizontal spacing between the door frame 1 and the pre-impact point of the furnace wall is completed; then the height of the entire device is adjusted by manual movement. In actual use, a height-adjustable foot can be installed at the bottom of the door frame 1, and the horizontal indicator line emitted by the straight line laser 503 of the horizontal alignment mechanism is coincident with the furnace eye on the furnace wall. The calibration of the entire height of the device is completed. At this time, the pre-impact point of the hammer 2 on the furnace wall coincides with the actual position of the furnace eye to be opened; the traction rope 401 of the lifting device 4 is pulled to lift the hammer 2 to a certain height, and then the traction rope 401 is freely released, and the hammer 2 falls and hits the furnace eye on the furnace wall to complete the eye opening operation.

[0021] The vertical alignment mechanism of the alignment device 5 uses two straight line lasers 503 on both sides of the hammer 2 to position the impact point of the hammer 2 on the furnace wall. By adjusting the two lines to coincide with each other, the distance from the door frame 1 to the furnace wall can be adjusted. The straight line laser 503 of the horizontal alignment mechanism can be used to indicate the height position of the impact point of the hammer 2, and can guide the adjustment of the height of the impact point of the hammer 2 to coincide with the furnace eye.
