Technical Field
[0001] The utility model relates to a gas collecting hood, in particular to a slag-removing and gas-collecting hood for an electric furnace opening, belonging to the technical equipment field of slag-removing and dust-removing for electric furnaces. Background Art
[0002] An electric furnace is a heating furnace that converts electric energy in the furnace into heat to heat workpieces. Compared with fuel furnaces, the internal temperature of electric furnaces is easier to control, the materials are heated quickly, the heating temperature is higher, the production process is easier to realize mechanization and automation, and it is more environmentally friendly, which is conducive to alleviating the increasingly serious environmental problems. After the electric furnace is frequently used, slag needs to be removed. However, the existing slag removal of electric furnaces is generally realized by a slag-removing machine in the form of a cantilever crane. During the operation of the slag-removing machine, the dust hood can only move away from the furnace opening, and the smoke and dust cannot be collected at this time, resulting in unorganized emissions. Therefore, further improvement is needed. Content of the Utility Model
[0003] The purpose of the utility model is to solve the above-mentioned disadvantages, and provide a slag-removing and gas-collecting hood for an electric furnace opening, which has a simple and reasonable structure, combines slag removal and dust collection, does not interfere with each other during use, and is convenient and fast during the use process.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] A slag-removing and gas-collecting hood for an electric furnace opening includes a gas collecting hood slidably connected to a track; a walking cross beam is arranged on the lower side of the gas collecting hood; an electric furnace is located under the walking cross beam; a translation hoisting mechanism is arranged on the walking cross beam; a slag-removing mechanism is connected to the lower end of the translation hoisting mechanism; a charging truck is arranged on one side of the electric furnace.
[0006] Further, the translation hoisting mechanism includes a support seat; sliding grooves are respectively arranged on the front and rear sides of the walking cross beam; the translation hoisting mechanism further includes a first driving end and a second driving end.
[0007] Further, a wheel axle seat is arranged on the upper part of the support seat; a guide wheel is arranged in the wheel axle seat; the first driving end is arranged outside the wheel axle seat; the first driving end is a motor; the first driving end is connected to the guide wheel.
[0008] Further, a chamber is arranged on the lower part of the support seat; a winding shaft is arranged in the chamber; the second driving end is arranged outside the chamber; the second driving end is a motor and is connected to the winding shaft; a steel wire strand is sleeved on the winding shaft.
[0009] Further, a hook is arranged at the bottom of the steel wire strand; the slag-removing mechanism is hung on the hook; the slag-removing mechanism includes a frame body.
[0010] Further, a cylinder is arranged inside the frame; a mechanical claw is hinged under the frame; a pushing seat is arranged between the mechanical claws.
[0011] Further, the piston of the cylinder is connected to the pushing seat.
[0012] The utility model has the following beneficial effects: An air collecting hood is added above the electric furnace. The air collecting hood can move left and right along the direction of the workshop on the track. When the air collecting hood stops above the furnace mouth, the smoke exhaust port at the upper end of the air collecting hood is docked with the suction pipeline of the dust collector. At this time, the soot is collected by the air collecting hood and then sucked away by the dust collector. A walking cross beam is installed on the air collecting hood. The installation direction of the walking cross beam is consistent with the walking direction of the air collecting hood. A translation hoisting mechanism (electric hoist) and a slag skimmer are installed on the walking cross beam. After the air collecting hood moves to the designated position, slag skimming operation is carried out. After the slag skimmer picks up the steel slag, it moves to the slag basin along with the electric hoist and puts the steel slag into the slag basin. When slag skimming operation is not carried out, the translation hoisting mechanism and the slag skimmer stop at the far end of the cross beam, without affecting other operations of the electric furnace.
