Abstract
The utility model relates to an emergency lifting mechanism of rotary furnace oxygen gun under sudden power failure accident during production of middle and small rotary furnaces. The mechanism comprises a pneumatic motor, a gas tank, an intake solenoid valve, an exhaust solenoid valve and a cutoff valve. The intake solenoid valve is connected on intake pipe of the pneumatic motor, the exhaust solenoid valve is connected on exhaust pipe of the pneumatic motor, the cutoff valve is connected with both the intake solenoid valve and the exhaust solenoid valve, the intake pipe and the exhaust pipe are connected with the gas tank, the pneumatic motor is connected with a main motor by a clutch. The utility model has advantages that small power is used and can lift heavy oxygen gun; used gas source is middle pressure nitrogen gas; fixed direction rotation of the pneumatic motor can be realized by the two solenoid valves; the two lower pressure solenoid valves can make intellectual operation under the situation that low pressure and short time UPS power supply is turned off at power failure accident and turned on immediately.
Description
Technical field
When the utility model relates to the power outage that burst takes place in the production process of medium and small converter, promote the mechanism of oxygen rifle.
Background technology
One of key equipment of modern copper metallurgy production technology is the oxygen rifle, and high pressure oxygen is blown into converter by oxygen lance spraying, and the Working environment of oxygen rifle is in 1700～1800 ℃ High Temperature Furnaces Heating Apparatus, and the cooling of rifle body is circulated by high pressure water and finishes.
But in the production process of Steel Plant, run into the power outage of some bursts through regular meeting, and this moment, if the oxygen rifle is just being caught up with and is being trapped in the pyritous stove, there has not been the circulation of water coolant, the akinesia again of main motor, just exist the rifle body and may be burnt out at any time, water enters the danger that produces blast in the molten steel; Do not having under the situation of large power supply, also will rise to the converter outside to the oxygen rifle, guaranteeing equipment and personnel safety, the most important.
Put forward the problem of oxygen rifle at accident, the method that adopts of some enterprises has following several at present:
When 1) accident takes place, open standby power supply, drive with joining pair of motor of main gear reducer by one, the accident of linking is carried rifle, this mode needs the regulating station, and pays motor not giving under the situation of electricity, also will turn round simultaneously with step-down gear, increased the wearing and tearing of equipment, only the investment of regulating station also is sizable.
2) also have some enterprises, the method that adopts counterweight to stick together.When being accidental state, need to impose certain power again, rifle is mentioned artificially by counterweight; Though this method cost is lower, accident appears and after, operator will go to the stove to handle, environment is not only arduous but also waste time.In addition, in the mill construction design, also to leave certain space, see lack of standardization on the whole.
3) some enterprises are arranged in addition, though adopted pneumatic motor to carry rifle,, this pneumatic motor power demand is very big, and the structure of step-down gear is special, needs special facture, does not also have a whole set of pneumatic control components and pneumatic control cabinet simultaneously, and cost is quite high.
Summary of the invention
The purpose of this utility model provides a kind of accident lifting mechanism of converter oxygen gun, the power outage of burst when taking place in this mechanism, can be in 1～2 minute time, with the minimum rifle position of oxygen rifle from converter, rise to the above optional position of fire door, stop the generation of serious accident, ensure safety in production.
For achieving the above object, the utility model is achieved through the following technical solutions:
The accident lifting mechanism of converter oxygen gun, it is characterized in that: this mechanism is made up of pneumatic motor, gas-holder, air inlet magnetic valve, exhaust solenoid valve, stopping valve, on the admission passage of pneumatic motor, be connected to the air inlet magnetic valve, on the exhaust line of pneumatic motor, be connected to exhaust solenoid valve, and on air inlet magnetic valve and exhaust solenoid valve, all be provided with stopping valve, admission passage and exhaust line are communicated with gas-holder, and pneumatic motor is connected with main motor by clutch coupling.
The utility model has the advantages that:
1) utilizes very little power, can promote heavier oxygen rifle.
2) used source of the gas is a middle pressure nitrogen (0.5Mpa gets final product).
3) just can reach the directed rotation of pneumatic motor by two magnetic valves.
4) pore element and housing that need not be loaded down with trivial details reach corresponding function equally.
5) two low-voltage solenoid valves are at ups power (low pressure, power supply in short-term are as emergency light), under the situation of OnNow, reach intelligent work with forced outage.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Embodiment
See Fig. 1, the accident lifting mechanism of converter oxygen gun, this mechanism is made up of pneumatic motor 5, gas-holder 4, air inlet magnetic valve 1, exhaust solenoid valve 2, stopping valve 3, on the admission passage of pneumatic motor, be connected to air inlet magnetic valve 1, on the exhaust line of pneumatic motor, be connected to exhaust solenoid valve 2, and all be provided with stopping valve 3 on air inlet magnetic valve 1 and exhaust solenoid valve 2, admission passage and exhaust line are communicated with gas-holder 4, and pneumatic motor 5 is connected with main motor by clutch coupling.
On the workplatform of oxygen lance lifting Traverse Displacement Unit, build a N
2Storage tank is with the byproduct N of oxyen manutactory
2Guide to this storage tank, be connected to pneumatic motor more by the road, in pipeline,, reach supply gas degassing function with cylinder push rod return of motor by air inlet magnetic valve 1 and exhaust solenoid valve 2.
When the oxygen rifle is in the stove, if by chance at this moment power supply system break down, operator, open the air inlet magnetic valve 1 of pneumatic motor just can start ups power at master control room, supply with the pneumatic motor source of the gas, exhaust solenoid valve 2 is closed simultaneously; Along with the rotation of pneumatic motor, power by step-down gear, through clutch coupling, is sent to main motor, by main motor process big retarding machine, drive the elevator rotation, thereby oxygen rifle in the converter is lifted out fire door again, avoid the generation of serious accident.
