Description
Technical field
The utility model belongs to the auxiliary mould of neodymium iron boron manufacture process pressing section, is specifically related to the automatic oxygen supplementing device of a kind of neodymium iron boron manufacture process pressing section.
Background technology
Pressing section in the magnetic materials production manufacture processes such as neodymium iron boron, owing to will controlling dust and aerial temperature and humidity, complete a relatively airtight place to whole pressing section, to ensure pressing section Production requirement.The micro mist that pressing section raw material used are neodymium iron boron, is exposed in air very easily oxidizing fire, in order to ensure neodymium iron boron micro mist quality, adopts canned nitrogen protection.A relative airtight space so aborning, due to personnel's oxygen expenditure and constantly adding of protection nitrogen, the oxygen content in space can constantly decline, and will very easily produce sense of fatigue and other injury to employee's health like this.
Utility model content
The purpose of this utility model is to provide and a kind ofly can automatically maintains the neodymium iron boron manufacture process pressing section automatic oxygen supplementing device of oxygen content in safe range in rubidium iron boron assembly room.
For achieving the above object, the utility model provides following technical scheme: the automatic oxygen supplementing device of a kind of neodymium iron boron manufacture process pressing section, comprise air accumulator, described air accumulator is communicated with compressed air source, on described air accumulator, be also provided with gas exhaust piping, described gas exhaust piping is communicated to the floss hole in rubidium iron boron assembly room, described gas exhaust piping is provided with magnetic valve, the switching signal input of described magnetic valve is electrically connected with the signal output part of oxygen content detector, and described oxygen content detector is arranged in rubidium iron boron assembly room;
The solenoid of described magnetic valve is connected with auxiliary reclay switch, and the solenoid of described auxiliary reclay is connected with the detection signal switch of oxygen content detector;
Manually experiment button is in parallel with one for described auxiliary reclay switch;
On described gas exhaust piping, be also provided with secondary accurate filter;
Pipeline between described compressed air source and air accumulator is provided with stop valve;
Described air accumulator bottom is provided with draining valve;
On described exhaust tank, be also provided with Pressure gauge and safety valve, described floss hole is multiple being arranged in parallel, and described each floss hole is evenly laid in rubidium iron boron assembly room.
Technique effect of the present utility model is: can automatically detect the oxygen content in rubidium iron boron assembly room, and can automatically carry out oxygenating to workshop, in addition, the utility model adopts compressed air source air feed and secondary secondary filter can effectively reduce the humidity of air to the impact of working environment, employing air accumulator cushions the influence of fluctuations to system pressure can effectively reduce device work time, adopt manually inspection, the operation conditions of testing arrangement effectively.
Brief description of the drawings
Fig. 1 is systematic schematic diagram of the present utility model;
Fig. 2 is circuit control principle drawing of the present utility model.
Detailed description of the invention
As shown in Figure 1, the automatic oxygen supplementing device of a kind of neodymium iron boron manufacture process pressing section, comprise air accumulator 6, described air accumulator 6 is communicated with compressed air source 1, on described air accumulator 6, be also provided with gas exhaust piping 9, described gas exhaust piping 9 is communicated to the floss hole 4 in rubidium iron boron assembly room, and described gas exhaust piping 9 is provided with magnetic valve 3, the switching signal input of described magnetic valve 3 is electrically connected with the signal output part of oxygen content detector, and described oxygen content detector is arranged in rubidium iron boron assembly room.Employing air accumulator 6 cushions the influence of fluctuations to system pressure can effectively reduce device work time.
As shown in Figure 2, the solenoid KM2 of described magnetic valve 3 connects with the switch of auxiliary reclay KM1, and the solenoid of described auxiliary reclay KM1 is connected with the detection signal switch C of oxygen content detector.Auxiliary reclay KM1 carries out insulation blocking detection signal and working electromagnet valve 3.
Manually experiment button S is in parallel with one for the switch of described auxiliary reclay KM1.Adopt manually inspection, the operation conditions of testing arrangement effectively.
On described gas exhaust piping 9, be also provided with secondary accurate filter 7; Pipeline between described compressed air source 1 and air accumulator 6 is provided with stop valve 8.Adopt compressed air air feed and secondary secondary filter can effectively reduce the humidity of air to the impact of working environment.
Described air accumulator 6 bottoms are provided with draining valve 5, and draining valve 5 is mainly the condensed water accumulating in regularly irregular discharge pipe.
On described air accumulator 6, be also provided with Pressure gauge 21 and safety valve 22, described floss hole 4 is multiple being arranged in parallel, and described each floss hole 4 is evenly laid in rubidium iron boron assembly room.Floss hole 4 is mainly to allow air evenly discharge in space, plays sound deadening simultaneously.
When normal, compressed air source 1 by air supply system to air accumulator 6 air feed.Along with the lengthening of Workshop Production time, the increase of nitrogen discharge amount, lower than 17% time, exports a switching signal to control loop when oxygen content detector detects oxygen content in workshop, thereby it is electric to allow electromagnetic valve coil KM2 obtain, opens magnetic valve 3 and supplement fresh compressed air to workshop.
This mechanism has overcome a relative shortcoming for anoxic in the space of sealing, after design improvement, has improved working environment, and the oxygen content of this device in can 24 hours continuous detecting workshops of whole day, automatically performs.
