Embodiment
Below in conjunction with the accompanying drawings, a kind of sulfur hexafluoride gas recovery of the present utility model is made furtherly with filter
It is bright.Following examples are only used for helping skilled in the art to understand the utility model, are not to limitation of the present utility model.
The recovery of sulfur hexafluoride gas needs to remove the moisture contained in gas, ensures sulfur hexafluoride gas in recovery with this
During have higher qualification rate.Moisture in gas is typically adsorbed by the filter core 5 being made up of adsorbent, filter core 5
The meeting saturation after absorption a period of time, now, it is necessary to changed to the filter core 5 of saturation, so that filter can be normal
Use.
As shown in figure 1, a kind of sulfur hexafluoride gas recovery filter, including housing 1, the housing 1 includes tubulose
Portion 2, the two ends of the tube 2 are respectively equipped with first end cap 3 and the second end cap 4 in closed tube portion 2, first end cap 3
It is welded on tube 2, at least two filter cores 5 is provided with the tube 2, filter core 5 is filled to the interior intracavitary of tube 2；
As shown in figure 1, second end cap 4 is fixed on tube 2 by bolt 6, integral type is set on the tube 2
There are the flanging 7 that bolt 6 is set, diametric(al) protrusion tube 2 of the flanging 7 along tube 2, also, the flanging 7 to protrude
The length of tube 2 is not less than 20 millimeters, and flanging 7 is provided with the through hole that bolt 6 can be passed through, and the setting of flanging 7 is except fixation
Outside second end cap 4, also increase the contact area of the end cap 4 of tube 2 and second so that the second end cap 4 and tube 2 it
Between have better seal performance, optimize the performance of filter；
As shown in figure 1, in order to further improve on the sealing property between the second end cap 4 and tube 2, the flanging 7
Sealing gasket 8 is bonded with, the sealing gasket 8 is located between the end cap 4 of flanging 7 and second, and sealing gasket 8 should can produce elastic deformation, close
Packing 8 is bonded on flanging 7, and filter is easy to assembling, in addition, bolt 6 is compressed after the second end cap 4, sealing gasket 8 produces elasticity
Deformation, the elastic deformation can play and locking effect is carried out to bolt 6, and sealing gasket 8 is shaped as annular；
As shown in figure 1, filter is only used for the moisture in adsorbed gas, the whole removal process of gas also needs to other
Processing equipment is participated in, and for ease of the connection of filter and other processing equipments, first end cap 3 is provided with exhaust nozzle 9, institute
State exhaust nozzle 9 and be provided with and open or close the air bleeding valve 10 of exhaust nozzle 9, second end cap 4 is provided with suction nozzle 11, it is described enter
Valve 11 is provided with the intake valve 12 for opening or closing suction nozzle 11；
As shown in figure 1, the exhaust nozzle 9 is welded on the first end cap 3, also, the exhaust nozzle 9 and the first end cap 3 are same
Axle, the suction nozzle 11 is welded on the second end cap 4, also, the suction nozzle 11 and the second end cap 4 are coaxial, positioned at tube 2
The interior volume of filter core 5 close to the second end cap 4 is more than the volume of filter core 5 away from the second end cap 4 in tube 2, and filter core 5 is closer to entering
Moisture in valve 11, easier adsorbed gas, that is to say, that the filter core 5 close to suction nozzle 11 is easily saturated, therefore, close
Larger volume can be set in the filter core 5 of suction nozzle 11, to optimize the performance of filter.
Above-mentioned technical proposal can be changed easily during specifically used after the saturation of filter core 5, and filter need not
Return factory and change filter core 5, user of service is the replacement operation that filter can be achieved, and the performance of filter is optimized, in addition, tubulose
At least two filter cores 5 are provided with portion 2, the absorption property of filter is optimized, the moisture in gas can be carried out as far as possible many
Absorption, improve the recovery quality of sulfur hexafluoride gas.
As shown in Figure 1 and Figure 2, a kind of prioritization scheme to such scheme, filter is in actual use, the saturation of filter core 5
Afterwards operating personnel typically can not directly judge filter core 5 whether saturation, be only capable of from the recovery quality of sulfur hexafluoride gas judge filter
Whether the saturation of core 5, this can not be changed in time after causing the saturation of filter core 5, therefore, the suction nozzle 11 is provided with detection air inlet
Whether have in mouth 11 and be fixed with alarm 14, timer 15 and controller 16 on the detector 13 that gas flows through, the housing 1,
The detector 13, timer 15 are communicated with controller 16, the time control that the controller 16 is counted according to timer 15
Alarm 14 is worked, and the detector 13 is threadedly secured on suction nozzle 11, and detector 13 can be arranged on suction nozzle 11
Side wall on, the controller 16 include shell 17, shell 17 can be fixed by screws on the second end cap 4, positioned at second
Screw on end cap 4 with screw fit should not run through the second end cap 4, to avoid causing gas to leak, the alarm 14 and meter
When device 15 be arranged in the shell 17 of controller 16, also, be additionally provided with battery 18 in the shell 17, the detector 13,
Alarm 14, controller 16 and timer 15 are powered by battery 18.
Whether the program records the adsorption time of filter core 5 using detector 13, timer 15, judge filter core 5 with this
Through saturation, its principle is that the moisture that filter core 5 is adsorbed is limited, and the volume of the unit interval interior gas by filter core 5 is generally
It is certain, thus, it is only required to which whether the adsorption time that record filter core 5 can determine whether the saturation of filter core 5, the internal memory of controller 16
Contain filter core 5 filtering time rating, timer 15 record the filtration time of filter core 5 be equal to controller 16 in setting it is specified when
Between when, controller 16 sends signal to alarm 14, and control alarm 14 is alarmed, to point out technical staff to change filter core 5.Realize
The controller 16 of above-mentioned functions is ordinary construction of the prior art.
The program sends alarm signal prompting technical staff in 5 saturation of filter core, optimizes the performance of filter.
Section Example of the present utility model is described in detail above in association with accompanying drawing.Those skilled in the art read
After this specification, based on the technical solution of the utility model, above-described embodiment can be modified, these modifications still fall within this
The protection domain of utility model.
