Abstract

The utility model provides an argon gas recovery unit, including argon gas buffer tank, diaphragm compressor, high -pressure tank container and pressure reducer. The one end intercommunication of low pressure stove is kept away from to diaphragm compressor's inlet end and argon gas buffer tank. High pressure tank container communicates with diaphragm compressor's the end of giving vent to anger. Pressure reducer one end can communicate with the import of low pressure stove with high -pressure tank container intercommunication, the other end to it is leading -in to the low pressure stove in with the high -pressure gas low pressure in the high -pressure tank container. In getting into the argon gas buffer tank after argon gas in the low pressure stove is discharged, and when pressure reaches designated value after, diaphragm compressor is with the argon gas compression extremely in the high -pressure tank container. Through the pressurization back, the volume of the gas that can save in the high -pressure tank container promotes greatly. And when needs during for low pressure stove air feed, the pressure reducer then becomes highly compressed argon gas into low pressure gas. Because the argon gas storage is at pressor high -pressure tank container, so the argon gas can not be because of just unable recovery behind the pressure balance. Through above -mentioned argon gas recovery unit, can effectively improve argon gas recovery efficiency.

Detailed description of the invention

For the ease of understanding this utility model, below with reference to relevant drawings, this utility model is described more fully。Accompanying drawing gives preferred embodiment of the present utility model。But, this utility model can realize in many different forms, however it is not limited to embodiment described herein。On the contrary, the purpose providing these embodiments is to make the understanding to disclosure of the present utility model more thorough comprehensively。

It should be noted that be referred to as " being fixed on " another element when element, it can directly on another element or can also there is element placed in the middle。When an element is considered as " connection " another element, it can be directly to another element or may be simultaneously present centering elements。

Unless otherwise defined, all of technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model are generally understood that。The purpose describing specific embodiment it is intended merely to herein, it is not intended that in restriction this utility model at term used in the description of the present utility model。Term as used herein " and/or " include the arbitrary and all of combination of one or more relevant Listed Items。

Referring to Fig. 1, the argon retracting device 100 in this utility model preferred embodiment includes argon surge tank 110, diaphragm type compressor 120, high pressure bulk bin 130 and decompressor 140。Argon retracting device 100 reclaims for the argon that low pressure furnace 10 is given off。

One end of argon surge tank 110 can connect with the outlet of low pressure furnace 20。When argon is discharged in low pressure furnace 20, it is directly entered in argon surge tank 110。

The inlet end of diaphragm type compressor 120 connects away from one end of low pressure furnace 20 with argon surge tank 110。High pressure bulk bin 130 connects with the outlet side of diaphragm type compressor 120, and the gas pressurized in argon surge tank 110 is injected in high pressure bulk bin 130 by diaphragm type compressor 120。Therefore, argon can store at high pressure bulk bin 130 inner high voltage, thus promoting the capacity of storage。

One end of decompressor 140 connects with high pressure bulk bin 130, and the other end can connect with the import of low pressure furnace 20, the gases at high pressure low pressure in high pressure bulk bin 130 to be directed in low pressure furnace 20。Owing to only low-pressure argon need to be filled with in low pressure furnace 20。Therefore, in high pressure bulk bin 130, the argon of storage is after decompressor 140 reduces pressure, and just meets Production requirement。

In the present embodiment, purification devices 150 it is additionally provided with between argon surge tank 110 and diaphragm type compressor 120。Purification devices 150 for carrying out the operation such as deoxygenation, filtration to the argon reclaimed。

Seeing also Fig. 2, purification devices 150 includes Primordial Qi quantifier 151, purification componentry 153, argon flow amount meter 155, hydrogenation tank 157, cooling tank 158 and steam trap 159。

The outlet of Primordial Qi quantifier 151 and argon surge tank 110。Gas in argon surge tank 110 enters purification devices 150 purification through Primordial Qi quantifier 151。Purification componentry 153 connects with Primordial Qi quantifier 151, and purification componentry 153 includes multiple purification tank 1532 being sequentially communicated, and purification tank 1532 is used for housing purified reagent。

Concrete, purification tank 1532 can hold desiccant, oxygen scavenger and adsorbent etc.。

Argon flow amount meter 155 connects with purification componentry 153, and the outlet of argon flow amount meter 155 connects with diaphragm type compressor 120。Argon surge tank 110 is after purification componentry 153 purification, and impurity is filtered out, and enters diaphragm type compressor 120 from argon flow amount meter 155。

Further, in the present embodiment, it is two groups that purification componentry 153 includes parallel with one another, and at least one the purification tank 1532 in purification componentry 153 accommodates oxygen scavenger。
