Description
Technical field
The utility model is related to a kind of aluminium powder hierarchy system and mends denitrogen device automatically.
Background technology
In production of aluminum powder, classification, existing classification line nitrogen protection is not accurate enough on denitrogen controlled atmosphere section is mended, operation with
Meaning property is high, nitrogen consumption is big, and often reflection nitrogen is not enough, and it is exceeded existing in classification running easily oxygen content occur
As there is potential safety hazard.It is mainly manifested in following aspect：
1st, system mends nitrogen：System benefit nitrogen control mode is single, is controlled mainly by the system oxygen content upper limit is set.Work as oxygen
When content is higher than the upper limit is set, mends nitrogen magnetic valve and open, system carries out benefit nitrogen.If system oxygen content detector breaks down,
System can be caused normally to mend nitrogen, the risk for causing system oxygen content exceeded.
2nd, system denitrogen：The control of system pressure, is adjusted mainly by operating personnel's open system atmospheric valve, in operation
When be difficult to hold valve opening.When emptying valve opening is excessive, system negative pressure height is easily caused, air is sucked by charging aperture,
Raise system oxygen content.The nitrogen for filling into system simultaneously is also discharged, and increases nitrogen consumption.
Utility model content
The purpose of this utility model is to solve above-mentioned problem of the prior art there is provided a kind of aluminium powder hierarchy system row of benefit automatically
Nitrogen device.
Aluminium powder hierarchy system of the present utility model mends the oxygen that denitrogen device includes being arranged in aluminium powder hierarchy system automatically
Analyzer, pressure transmitter, the PLC being connected with oxygen analyzer and pressure transmitter (programmable logic controller (PLC)), with aluminium
The denitrogen device and benefit nitrogen device of powder hierarchy system connection, denitrogen device include the mistake being connected by pipeline with aluminium powder hierarchy system
Filter, the magnetic valve controlled by PLC set on filter outlet pipeline, mending nitrogen device includes passing through pipeline and aluminium
The nitrogen supply source of powder hierarchy system connection and the magnetic valve controlled by PLC being arranged on the pipeline.
It is general to mend the gas balance tank equipment that nitrogen device, denitrogen device are connected to aluminium powder hierarchy system by pipeline respectively,
Mend nitrogen device to be connected in the middle part of gas balance tank, denitrogen device is connected to gas balance tank top.
The operating process that aluminium powder hierarchy system of the present utility model mends denitrogen device automatically is as follows：Detected by oxygen analyzer
Aluminium powder hierarchy system oxygen content gives PLC signal, when aluminium powder classification linear system system oxygen content is higher than setting value, PLC controls
Device processed gives signal, opens magnetic valve and carries out benefit nitrogen.When aluminium powder classification linear system system oxygen content is less than setting value, PLC
Signal is given, magnetic valve is closed and stops mending nitrogen.
Detect that aluminium powder hierarchy system pressure gives PLC signal by pressure transmitter, when aluminium powder classification linear system system
When pressure is higher than setting value, PLC gives signal, opens magnetic valve and carries out denitrogen via filter.When aluminium powder is classified line
When system pressure is less than setting value, PLC gives signal, closes magnetic valve and stops denitrogen.
Advantage of the present utility model
Aluminium powder hierarchy system of the present utility model mends denitrogen device automatically makes aluminium powder hierarchy system maintain a pressure-fired, together
When ensure that hierarchy system oxygen content is effectively controlled in safe range, prevent that operation is random, cause system oxygen content liter, it is ensured that point
Level system operation safety.Nitrogen consumption is reduced simultaneously.
Brief description of the drawings
Fig. 1 is the schematic diagram that aluminium powder hierarchy system of the present utility model mends denitrogen device automatically.
Embodiment
Include being arranged on aluminium powder classification system as shown in figure 1, aluminium powder hierarchy system of the present utility model mends denitrogen device automatically
Oxygen analyzer 6, pressure transmitter 5 in system 7, the PLC 1 being connected with oxygen analyzer and pressure transmitter, with aluminium powder point
The denitrogen device 4 and benefit nitrogen device 2 of level system connection, denitrogen device 4 include the filter being connected by pipeline with hierarchy system
3, the magnetic valve 9 controlled by PLC set on filter outlet pipeline, mending nitrogen device 2 includes passing through pipeline and aluminium
The nitrogen supply source (not shown) of powder hierarchy system connection and the magnetic valve 8 controlled by PLC being arranged on the pipeline.
The gas balance tank equipment that nitrogen device 2, denitrogen device 4 are connected to hierarchy system 7 by pipeline respectively is mended, nitrogen dress is mended
Put 2 to be connected in the middle part of gas balance tank, denitrogen device 4 is connected to gas balance tank top.
The operating process that aluminium powder hierarchy system of the present utility model mends denitrogen device automatically is as follows：Examined by oxygen analyzer 6
Survey the oxygen content of aluminium powder hierarchy system 7 and give PLC signal, when aluminium powder classification linear system system oxygen content is higher than setting value, PLC
Controller 7 gives signal, opens magnetic valve 8 and carries out benefit nitrogen.When aluminium powder classification linear system system oxygen content is less than setting value, PLC controls
Device processed gives signal, closes magnetic valve 8 and stops mending nitrogen.
Detect that aluminium powder hierarchy system pressure gives PLC signal by pressure transmitter 5, when aluminium powder classification linear system system
When 7 pressure are higher than setting value, PLC 1 gives signal, opens magnetic valve 9 and carries out denitrogen via filter 3.When aluminium powder point
When level line system pressure is less than setting value, PLC 1 gives signal, closes magnetic valve 9 and stops denitrogen.
Aluminium powder hierarchy system of the present utility model mends denitrogen device automatically makes aluminium powder hierarchy system maintain a pressure-fired, together
When ensure that hierarchy system oxygen content is effectively controlled in safe range, prevent that operation is random, cause system oxygen content liter, it is ensured that point
Level system operation safety.Nitrogen consumption is reduced simultaneously.
