Abstract
The utility model discloses a continuous feeding equipment of a waste material pre-heating electric arc furnace, comprising a feeding hopper with an upward inlet and an outlet which is close to a feeding opening of an electric arc; the feeding hopper is fixedly arranged on a supporting frame; one side of the feeding hopper is provided with a belt conveying system with a feeding end which is lower than a discharging end; and the discharging end of the belt conveying system is located above the inlet of the feeding hopper and is connected with the inlet of the feeding hopper. According to the continuous feeding equipment of the waste material pre-heating electric arc furnace, materials are conveyed into the feeding hopper by the belt conveying system and the materials are added into the electric arc furnace by the feeding hopper; and the belt conveying system can continuously convey the materials into the feeding hopper and the feeding hopper can continuously add the materials into the electric arc furnace to realize continuous material feeding. Therefore, in a whole working process of the electric arc furnace, the materials are added into the electric arc furnace all the time and the condition that the materials do not exist in the electric arc furnace is avoided; and an energy source of the electric arc furnace is sufficiently utilized and the waste of the energy source is not caused.
Description
Technical field
The utility model relates to a kind of waste material preheating electric arc furnaces continuous charging equipment that is used to the electric arc furnaces continuous charging of waste material preheating.
Background technology
Electric arc furnaces is to utilize electric arc to produce high temperature material is carried out preheating or carries out the melting of ore or metal.The body of heater of electric arc furnaces is comprised of bell, fire door and shaft, and furnace temperature is controlled easily, and occupation area of equipment is little, is desirable heating and smelting equipment.Generally speaking, the temperature of electric arc furnaces is all relatively high, so, the equipment reinforced for electric arc furnaces generally all is automation equipment, and now, electric arc furnaces is mainly used in smelting metal or ore, because metal or the smelting time of ore are all longer, therefore, need to wait that to carry out for a long time second time reinforced again after once reinforced, so charging system commonly used all is the charging system at intermittence in the prior art.When electric arc furnaces is used for carrying out the preheating of material, because the required temperature that obtains of material is relatively low during preheating, so the time that material stops in electric arc furnaces is just shorter, this is if take intermittence of the prior art charging system to feed in raw material and will cause electric arc furnaces to have the situation of no-load running, that is to say, sometimes do not have material in the electric arc furnaces, but electric arc furnaces also needs work, obviously this will cause the waste of the energy.
The utility model content
The object of the present invention is to provide a kind of waste material preheating electric arc furnaces continuous charging equipment, adopt charging system and the problem of the energy waste that causes at existing intermittence when carrying out the material preheating to solve when electric arc furnaces.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of waste material preheating electric arc furnaces continuous charging equipment, comprise that import is used for loading hopper with the charging aperture adjacency of electric arc towards upper outlet, loading hopper is fixedly installed on the bracing frame, one side of loading hopper is provided with the belt conveyor system that feed end is lower than discharge end, the discharge end of belt conveyor system be in loading hopper import the top and join with the import of loading hopper.
Be fixedly installed electromagnetic oscillation device on the outer wall of described loading hopper.
Described bracing frame comprises the gripper shoe on top, described loading hopper is fixedly installed on the bracing frame by gripper shoe, offer on the gripper shoe hole is set, the discharge port end of loading hopper passes the hole is set, loading hopper is fixedly installed on the gripper shoe, the bottom of gripper shoe is fixedly installed supporting leg, and described supporting leg is telescopic outrigger.
Waste material preheating electric arc furnaces charging (feeding) equipment of the present utility model is transported to material in the loading hopper by belt conveyor system, and by loading hopper material is added in the electric arc furnaces, belt conveyor system can be continuous material is transported in the loading hopper, loading hopper just can be continuous material is added in the electric arc furnaces, realize continuous charging.In the whole course of work of electric arc furnaces, have all the time material and add in the electric arc furnaces like this, avoid occurring in the electric arc furnaces not having the situation of material, take full advantage of the energy of electric arc furnaces, can not cause the waste of the energy.
Be provided with electromagnetic oscillation device on the outer wall of loading hopper of the present utility model, electromagnetic oscillation device can drive loading hopper and vibrate together, so that the material in the loading hopper can enter in the electric arc furnaces smoothly, prevents the material knot arch in the loading hopper.
Supporting leg of the present utility model is telescopic outrigger, and the length of adjusting telescopic outrigger can drive gripper shoe rising or reduction, and gripper shoe can drive loading hopper and move up and down, thereby adapts to the electric arc furnaces of differing heights, strengthens range of application of the present utility model.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model embodiment.
The specific embodiment
A kind of embodiment of waste material preheating electric arc furnaces continuous charging equipment, in Fig. 1, its loading hopper 1 integral body is the loading hopper of del, the import of loading hopper 1 is towards the top, the bottom of loading hopper 1 has the diversion section of inclination, the lower port of diversion section is the outlet of loading hopper 1, and the outlet of loading hopper 1 is used for the charging aperture adjacency with electric arc furnaces, thereby feeds in raw material for electric arc furnaces.Loading hopper 1 is arranged on the gripper shoe 3 of bracing frame, offers on the gripper shoe 3 hole is set, and the discharge port end of the close discharging opening of loading hopper 1 passes the hole is set, and loading hopper 1 is fixedly installed on the gripper shoe 3.The bottom of gripper shoe 3 is provided with supporting leg 4, and the upper end of supporting leg 4 is fixedly installed on the gripper shoe 3, and supporting leg 4 can support feed hopper 1 and arrange on the ground.Supporting leg 4 in the present embodiment is telescopic outrigger, can adjust length, thereby adjusts the height of loading hopper, to adapt to multi-form electric arc furnaces.
Lateral wall at loading hopper 1 is fixedly installed electromagnetic oscillation device 5, and the electromagnetic oscillation device 5 here is prior art.Electromagnetic oscillation device can drive the loading hopper vibration, prevents the material knot arch in the loading hopper.
Side at loading hopper 1 is provided with belt conveyor system 2.The feed end of belt conveyor system 1 is lower than discharge end, the discharge end of belt conveyor system 2 be in loading hopper import the top and join with the import of loading hopper 1.Belt conveyor system 2 can upwards be carried the material that is in lower and send in the loading hopper.Thereby material sent into carry out preheating in the electric arc furnaces.
Supporting leg in the present embodiment is telescopic outrigger, when the electric arc furnaces that only is used for one type, also supporting leg can be arranged to non-retractable fixed supporting leg.
The form of telescopic outrigger is a lot, such as hydraulic pressure, vapour-pressure type, the screw rod threaded-insert type, application is all arranged in the prior art, be not described in detail in this.
