Abstract
The utility model relates to a novel energy-saving technology which belongs to the field of pneumatic system energy conservation. A delay control mode mainly aims at the air loop control of a crust breaking cylinder of the electrolytic aluminium industry, the air leakage rate of the crust breaking cylinder can be greatly reduced, and the utilization rate of compressed air is increased. The delay control mode is used on the air loop control of the crust breaking cylinder of the electrolytic aluminium industry, and air supply pressure is reasonably switched according to the requirements of working conditions through air supply pressure remote control. When a crust breaking signal exists, a directional control valve of a partial pressure air supply loop is reversed to supply air source pressure, so that the crust breaking cylinder extends out; when the crust breaking signal disappears, the directional control valve is maintained unchanged through a time delay device, the air source pressure is also supplied, so that the crust breaking cylinder retracts; and when the time delay is reached, the directional control valve is reversed, the air supply pressure is reduced to be supplied for the crust breaking cylinder, the crust breaking cylinder enters a maintaining state at low pressure, the air leakage rate of the crust breaking cylinder is reduced, the air consumption is reduced, and an energy-saving purpose is realized.
Description
Technical field:
The invention belongs to energy-saving field of pneumatic, relate to the pneumatic control system of aluminum electrolysis industry.
Background technology:
The air consumption of aluminum electrolysis industry crust breaking cylinder accounts for more than 40% of whole plant compressed air usage quantity, impact on whole plant energy consumption is most important, and effectively reducing the compressed-air actuated consumption of crust breaking cylinder, raising cylinder pressurized air service efficiency is to solve the energy-conservation effective way of aluminum electrolysis industry pneupress system.
Crust breaking cylinder is energy-conservation to be the key component of energy-saving field of pneumatic in the aluminum electrolysis industry, pneumatic system is because the adjusting of low, pollution-free, the easy care of cost, power output and working speed such as is very easy at the advantage plays an important role in industrial automation, but the energy consumption of crust breaking cylinder accounts for pneumatic system total energy consumption significant proportion and capacity usage ratio is not high.In today that energy problem becomes increasingly conspicuous, the energy-conservation of crust breaking cylinder has great significance to the energy-saving and cost-reducing of aluminum electrolysis industry.
The air feed of domestic and international existing crust breaking cylinder is to adopt single forced air supply, i.e. stretching out, retracting and all adopt identical bleed pressure air feed during maintenance at crust breaking cylinder.Because electrolyzer temperature is high, the easy impaired inefficacy of sealing in the cylinder end piece of the piston rod side of crust breaking cylinder is leaked serious when cylinder keeps.Be head it off, this patent changes the air feed of cylinder into high pressure and two kinds of forced air supplies of low pressure by single pressure.Cylinder stretch out or when retracting because high pressure gas are supplied with in the requirement of technique, and the air feed that reduces pressure when cylinder keeps is realized energy control for need like this, can reduce the leakage under the cylinder maintaining condition, the reduction compressed air consumption.
Summary of the invention:
Purpose of the present invention:
For aluminum electrolysis industry provides a kind of novel energy-conserving crust breaking Decompression Controlling winding machine solar term more than 30%.

The electrical delay device is comprised of time-delay cut-off switch and timing register, and its delay time is set by timing register.
2 but crust breaking signal when adopting pneumatic control signal:
When the crust breaking pneumatic singal sometimes, dividing potential drop is supplied with bleed pressure for the commutation of the direction control valve (2) of air circuit, crust breaking cylinder (1) stretches out; When the crust breaking pneumatic singal disappeared, by Pneumatic time delay device, direction control valve (2) remained unchanged, and still supplies with bleed pressure, and crust breaking cylinder (1) is retracted; When delay time reaches, direction control valve (2) commutation, bleed pressure is supplied with crust breaking cylinder (1) after through decompression, and crust breaking cylinder (1) enters maintaining condition under low pressure.
Pneumatic time delay device is composed in parallel by air-capacitor (6) and check valve (7).When the crust breaking pneumatic singal was opened, (4) flowed into the signal air-flow from the gas inlet, are full of air-capacitor (6) in the time of to pneumatic outlet (5) output gas flow; During the crust breaking signal at stop, the signal air-flow stops inflow gas entrance (4), is stored in the gas of air-capacitor (6) to pneumatic outlet (5) or restriction (8) output gas flow, and pressure descends gradually.Its delay time is set by the opening degree of adjusting joint head piece (8).
