Description
Technical field
The utility model relates to a kind of equipments of making nitrogen with frequency conversion air compressor, belong to magnetic powders technology of preparing neck
Domain.
Background technique
In permanent-magnet material production technology, need to carry out powder processed, airflow milling to sintered permanent-magnet alloy using airflow milling
It is to be milled when work using nitrogen, it is therefore desirable to the equipment of making nitrogen is used, the equipment of making nitrogen provides compressed air by air engine,
Compressed air carries out pressure-variable adsorption in two adsorption towers and produces nitrogen.Air compressor machine in traditional scheme is driven using ordinary motor,
Air compressor machine is full loading operation.And in certain periods due to scheduling of production, small to the consumption of nitrogen, the nitrogen produced excessively is wanted
Discharge, and full load state is also wanted in the operation of air compressor machine, wastes energy consumption.
Utility model content
The purpose of this utility model is to provide a kind of equipments of making nitrogen with frequency conversion air compressor, the specific scheme is that
A kind of equipment of making nitrogen with frequency conversion air compressor including the air compressor machine for providing compressed air and is used to prepare nitrogen
Two adsorption towers in parallel, the air compressor machine is connected with frequency converter, and air compressor machine is set in a refrigeration case, and refrigeration case includes being equipped with
The cabinet of insulating layer, cabinet are equipped with vortex cooler, and the cold side outlet for being vortexed cooler is connected to box house；Two adsorption towers
Equipped with exhaust outlet, the exhaust outlet is connected to the air inlet of vortex cooler.
Further, the refrigeration case is rectangular box, and one end of rectangular box is equipped with cold air interface, cold air interface and whirlpool
The cold side outlet connection of cooler is flowed, the other end of rectangular box is equipped with thermovent；The bottom of rectangular box is equipped with for installing
The top of the bottom plate of air compressor machine, rectangular box is equipped with openable top cover.
Further, compressed air reservoir is connected between the exhaust outlet of the adsorption tower and vortex cooler, compression is empty
The outlet of gas storage tank is equipped with control valve.
The beneficial point of the utility model is: the equipment of making nitrogen of this programme uses the motor driven air compressor machine with frequency converter,
Compressed air is provided for the equipment of making nitrogen, to air compressor machine attached with frequency converters, constant-pressure pressure to 0.65-0.70MPA.Air compressor machine is from full range
Operation becomes variable frequency work, meets equipment normal work, reduces energy consumption.
Since the calorific value of frequency conversion air compressor motor when loading low is high, it is easy to burn coil, especially with ordinary motor
Based on the air compressor machine of Frequency Conversion Modification is carried out by additional frequency converter, above-mentioned heating problem is more prominent.Therefore this programme will be empty
Press is wholy set in a refrigeration case, and refrigeration case provides cold source using vortex cooler, can integrally be carried out to air compressor machine cold
But.In addition, being the pressure-air being discharged during nitrogen processed using two adsorption towers when vortex cooler refrigeration, while can rise
To the recycling incidental energy of pressure-air, energy-saving effect is played.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
A kind of equipment of making nitrogen with frequency conversion air compressor as shown in Figure 1, including for providing 1 He of air compressor machine of compressed air
Two adsorption towers 2 in parallel of nitrogen are used to prepare, the air compressor machine is connected with frequency converter, and air compressor machine is set in a refrigeration case 3,
Refrigeration case includes the cabinet equipped with insulating layer, and cabinet is equipped with vortex cooler 4, is vortexed in the cold side outlet and cabinet of cooler 4
Portion's connection；Two adsorption towers 2 are equipped with exhaust outlet 5, and the exhaust outlet 5 is connected to the air inlet of vortex cooler 4.Air compressor machine 1
Specific structure uses the usual manner of the prior art, and air compressor machine 1 is driven using the motor for being connected with frequency converter.
The refrigeration case 3 is rectangular box, and one end of rectangular box is equipped with cold air interface 301, and cold air interface and vortex are cold
But the cold side outlet connection of device 4, the other end of rectangular box are equipped with thermovent 302；The bottom of rectangular box is equipped with for installing
The top of the bottom plate 303 of air compressor machine, rectangular box is equipped with openable top cover 304.
Compressed air reservoir 6, compressed air reservoir are connected between the exhaust outlet 5 and vortex cooler 4 of the adsorption tower 2
6 outlet is equipped with control valve 7.Compressed air reservoir 6 is used for storing compressed air, according to practical condition to vortex cooler

The equipment of making nitrogen of this programme uses the motor driven air compressor machine with frequency converter, provides compressed air for the equipment of making nitrogen,
To air compressor machine attached with frequency converters, constant-pressure pressure to 0.65-0.70MPA.Air compressor machine becomes variable frequency work from full range operation, and satisfaction is set
It is standby to work normally, reduce energy consumption.
Since the calorific value of frequency conversion air compressor motor when loading low is high, it is easy to burn coil, especially with ordinary motor
Based on the air compressor machine of Frequency Conversion Modification is carried out by additional frequency converter, above-mentioned heating problem is more prominent.Therefore this programme will be empty
Press is wholy set in a refrigeration case, and refrigeration case provides cold source using vortex cooler, can integrally be carried out to air compressor machine cold
But.
Being vortexed cooler is a kind of efficient refrigeration equipment, by inputting the compressed air of certain pressure, passes through vortex tube
Internal energy conversion, one end generate cold air, and one end generates hot-air, to realize refrigeration.Vortex cooler does not need electric power
Driving is driven using compressed air completely.Vortex cooler in the present embodiment is to utilize two adsorption towers when freezing
The pressure-air being discharged during nitrogen processed, while the recycling incidental energy of pressure-air can be played, play energy-saving effect.
