Description
Technical field:
The present invention is used for the industrial ventilation system, is used in particular for the nuclear island of nuclear power station ventilating system, and when casing put into operation, middle radioaerosol (radioactive dust) or radioiodine purified air and purify air.The medium that is suitable for is air, coal gas, alpha-contamination air etc. arranged, and operating pressure≤3000Pa has nuclear safety function, and operating temperature is between+5 ℃～200 ℃, and maximum relative humidity is 100%.One or more filter cores unit is installed in each casing.
Background technology:
The leakage rate of the filter box-body of industrial ventilation system employing at present itself is bigger, can not play the purpose that air is effectively filtered; Can not effectively control the filter core that is used to filter alpha-contamination air, cause secondary pollution easily; Filter core is changed overlong time, thereby increases the time that the staff accepts irradiation.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, a kind of good sealing effect, the antipollution filter box-body of wearing quick clamp shaft of renew cartridge efficient height, the secondary pollution that caused when having reduced more renew cartridge more are provided.
For achieving the above object, technical scheme provided by the invention is: include cabinet shell, Box Cover, box spanner, locking member, sleeve, the lid sealing ring, filter core, the foaming PVC sealing gasket, operating grip, quick clamp shaft, the filter core carriage, cam, one or more filter cores unit is installed in every casing, the filter core unit is installed on the operating surface of casing, the installing port of each filter core unit all seals with Box Cover, each Box Cover is fixed on the cabinet shell with at least four locking members, box spanner hangs on the cabinet shell, the corresponding filter core unit of each sleeve, be welded in the filter core installing port place on the casing operating surface, Box Cover is set on the sleeve, Box Cover is provided with and covers sealing ring, and adopt plug-in strip shape sealing means between the sleeve, each Box Cover is fixed on the cabinet shell with four locking members, the foaming PVC sealing gasket sticks on filter core and the casing contact-making surface, filter core is installed on the filter core carriage, the filter core carriage supports by the cam that is installed on the quick clamp shaft, and operating grip is installed in quick clamping the tip of the axis.
The present invention causes secondary pollution for preventing contaminated filter core, the installing port of each filter core all has a sleeve, the ad hoc groove that is useful on the lock sealing bag on the sleeve can be realized " bag advances bag and goes out " function, and filter core farthest reduces contaminated filter core when changing and causes secondary pollution.For for convenience detach, Box Cover adopts locking member and box spanner, more during renew cartridge, unclamps locking member on the Box Cover by box spanner, has reduced the replacing time of filter core and the time that the staff accepts irradiation.For guaranteeing the sealing of filter core and casing contact-making surface, filter plant has quick clamp shaft.Adopt the foaming PVC sealing gasket between filter core and the casing,, adopted cam mechanism for guaranteeing the crush of sealing gasket.This quick clamp shaft can be implemented in the interior release of a few times in second or compress filter core, has reduced the replacing time of filter core and the time that the staff accepts irradiation widely.
Description of drawings:
Fig. 1 is an antipollution filter box-body schematic diagram of wearing quick clamp shaft.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is a filter core assembly structure schematic diagram.
The specific embodiment:
Referring to Fig. 1-shown in Figure 3, present embodiment includes cabinet shell 1, Box Cover 2, box spanner 3, locking member 4, sleeve 5, lid sealing ring 6, filter core 7, foaming PVC sealing gasket 8, operating grip 9, clamp shaft 10, filter core carriage 11, cam 12 fast.
Referring to shown in Figure 1, present embodiment is except that encapsulant, and all the other critical piece materials are stainless steel.One or more filter cores unit is installed in every casing, and the filter core unit is installed on the operating surface of casing, and the installing port of each filter core unit all seals with Box Cover.Each Box Cover 2 is fixed on the cabinet shell 1 with four locking members 4, and box spanner 3 hangs on the cabinet shell 1.
Referring to Fig. 2, shown in Figure 3, the corresponding filter core unit of each sleeve is welded in the filter core installing port place on the casing operating surface, and Box Cover 2 is set on the sleeve, and Box Cover is provided with and covers sealing ring 6, and adopts plug-in strip shape sealing means between the sleeve 5.Each Box Cover 2 is fixed on the cabinet shell 1 with four locking members 4.Foaming PVC sealing gasket 8 sticks on filter core 7 and the casing contact-making surface, and filter core is installed on the filter core carriage 11, and the filter core carriage supports by the cam 12 that is installed on the quick clamp shaft 10, and operating grip 9 is installed in quick clamping the tip of the axis.
Low leakage function of the present invention is achieved in that
The whole Welding Structure that adopts of casing, the weld seam of influential sealing all adopt the mode of continuous welding; Box Cover 2 is provided with and adopts plug-in strip shape sealing means between the sleeve 5 that covers on sealing ring 6 and the casing, can guarantee good seal.Filter core 7 is pasted foaming PVC sealing gasket 8 with casing contact-making surface place, can effectively prevent the air-flow short circuit, guarantees that air all passes through the filtration of filter core.
This ventilating system reduces filter core with filter box-body and causes the function of secondary pollution to be achieved in that
The installing port of each filter core all has a sleeve 5, the ad hoc groove that is useful on the lock sealing bag on the sleeve, first sack with sealing bag was set on the sleeve and at groove and fastens with rope when filter core was changed, the filter core that to change is again put in the sealing bag, realize " bag advances bag and goes out " function, farthest reduce contaminated filter core and cause secondary pollution.For for convenience detach, Box Cover 2 adopts locking members 4, more during renew cartridge, unclamps locking member on the Box Cover by box spanner 3, pulls down Box Cover easily, thereby has reduced the replacing time of filter core and the time that the staff accepts irradiation.
Quick substrate hold-down function of the present invention is achieved in that
For guaranteeing the sealing of filter core and casing contact-making surface, the filter core element has quick clamp shaft 10.Adopt foaming PVC sealing gasket 8 between filter core and the casing,, adopted cam 12 mechanisms for guaranteeing the crush of sealing gasket.When being installed, filter core earlier the operating grip 9 on the two quick clamp shafts is pulled out, and it is inwardly rotated to pasting the cover tube bottom, load onto filter core then and it be pushed into the filter core outward flange concordant with filter core carriage 11 outward flanges, again two operating grips are outwards rotated in the half round cut of reserving on the casing operating surface handle pushed home; Operating sequence when discharging filter core is then opposite, and this quick clamp shaft can be implemented in the interior release of a few times in second or compress filter core, has reduced the replacing time of filter core and the time that the staff accepts irradiation widely.
