Abstract
The utility model discloses a nitrogen supply device for the laser cutting machine, relating to a gas supply system for the laser cutting machine, the nitrogen supply device is a nitrogen storage vaporization device. The utility model can improve the nitrogen utilization rate when using the laser cutting machine, and can reduce the transportation costs. According to 300 work days in one year and 8 hours in one work day, the gas of the laser cutting machine is consumed 66 cubic meters in one hour, and each steel cylinder can use 4.21 cubic meters gas according to the price of the steel cylinder gas and the price of the liquid nitrogen, saving more than 1500000 RMB every year.
Description
Technical field: technical solutions of the utility model relate to the gas air feeder, particularly laser beam cutting machine gas air feeder.
Background technique: in the prior art, laser beam cutting machine needs highly purified gas as laser generation gas and cutting gas, carrying out the cutting of steel plate and stainless steel working piece, when particularly stainless steel working piece being cut, need nitrogen, and the nitrogen air feed of existing laser beam cutting machine gas air feeder is a steel cylinder with big flow.Use above-mentioned laser beam cutting machine gas air feeder, the defective of existence is, because the equipment atmospheric pressure is 2.9Mpa, must leave the overbottom pressure of 3Mpa so after the each use of steel cylinder, has 1/4 gas not utilize in the steel cylinder approximately; Again because during the cutting of workpiece, the consumption of nitrogen is bigger, has also increased the expense of transportation.Therefore, cause the defective that the laser beam cutting cost of use is excessive, cost is too high of workpiece.
Summary of the invention:
Technical problem to be solved in the utility model is to design a kind of laser beam cutting machine gas nitrogen air feeder, to solve the excessive technical problem of gas residue that prior art exists.
The technological scheme of the utility model technical solution problem is that its laser beam cutting machine nitrogen air feeder is that liquid nitrogen stores vaporizing unit.Adopt this basic technical scheme, can realize the liquid nitrogen vaporization at laser machine scene, the nitrogen after the vaporization is directly supplied with the cutting device of laser beam cutting machine, make the purity of nitrogen reach 99.999%, has overcome the technical problem that there is residual gas in the prior art nitrogen bottle.
Liquid nitrogen stores vaporizing unit mainly to be made up of liquid nitrogen storage tank, Dewar jar, vaporizer and pipeline decompressor, and liquid nitrogen storage tank, Dewar jar, vaporizer and pipeline decompressor connect in turn.
Owing to adopt technique scheme, the utility model has greatly improved the nitrogen utilization ratio when laser beam cutting machine uses, reduced the freight cost, by 1 year 300 Working day, 8 hours Working day, 66 cubic metres of laser beam cutting machine gas consumption per hours, every steel cylinder reality can utilize 4.21 cubic metres of gases and steel cylinder gas price and liquid nitrogen calculation of price now, more than 150 ten thousand yuan of the RMB of can reducing expenses every year.
Description of drawings:
Fig. 1 is a kind of example structure schematic representation of optimal design.
In the drawings: storage tank 1; Dewar jar 2; Vaporizer 3; Pipeline decompressor 4; Stop valve 5.
Embodiment:
A kind of laser beam cutting machine gas nitrogen air feeder, it stores vaporizing unit for liquid nitrogen.On concrete structure, it mainly is made up of storage tank 1, Dewar jar 2, vaporizer 3 and pipeline decompressor 4, and storage tank 1, Dewar jar 2, vaporizer 3 and pipeline decompressor 4 connect in turn.Storage tank 1 is for storing the container of 5 cubic metres of liquid nitrogen.Dewar jar 2 is provided with cryogenic liquid pump.Endothermic plate is equipped with in vaporizer 3 outsides.Low temperature liquid nitrogen is forced into 3Mpa through Dewar jar 2, and at this moment, the liquid nitrogen after the vaporization heat absorption changes gaseous state into by liquid state, and decompressor 4 is decompressed to 2.9Mpa by the road, is transported to the laser beam cutting machine cutting device by stop valve 5, carries out the cutting process of workpiece.
