Abstract
The utility model relates to a structure of a nuclear level air clearing machine, in particular to a contracting device of a filter of a nuclear level air clearing machine. The contracting device comprises a tightly pulling screw rod which is arranged at one side of the filter. The tightly pulling screw rod connects with a filter box via a screw thread. A tightly pulling handle is arranged at one end of the tightly pulling screw rod which is positioned outside of the filter box. By applying the utility model the structure of the tightly pressed device is predigested, the manufacture material is saved, filter modulation is more convenient and the filter seal is closer.
Description
Technical field
The utility model relates to a kind of structure of examining grade air cleaning unit, is specially a kind of hold down gag that is used to examine the air cleaner filtrator.
Background technology
In the nuclear engineering project, must the air that have radioaerosol be purified, it is to be used for the air strainer of various nuclear engineering projects and the erecting device of adsorber that existing P J series filter element is installed framed bent, its shortcoming is that device can not move, and the dismounting of filtrator is also inconvenient; GSD series high vacuum dedusting descaling machine is a kind of novel dedusting cleaning equipment of doing wet, smog, fiber multifunctional, and its shortcoming is that equipment volume is huge, and nuclear level filtration efficiency is low, and the uncomfortable synkaryon level of filtrator type selecting is used, and the operating noise of equipment is big.
Name is called " air purification dolly ", and the patent No. is the utility model patent of ZL200420000023.4, and a kind of device that is used to filter the on-the-spot radioaerosol of nuclear engineering is provided.This device is compared with original stationary installation has the advantages such as mobile operational process that volume is less, can move freely location, convenient scene in less space.But this device still exists deficiency: the cam drive hold-down frame of cartridge is regulated difficulty, former patent is designed to the cam drive hold-down frame, hold out against cartridge again and finish the sealing of cartridge and air port framework, the cam orientation adjusting screw of this design is regulated narrow space, and the adjustment of cam four point locations is difficulty very.
Summary of the invention
The purpose of this utility model is the defective at existing nuclear air cleaner cartridge compressing structure, and a kind of on-the-spot installation of being convenient to is provided, and is easy to adjust, makes the filtrator sealing examine the hold down gag of air cleaner filtrator more closely.
The technical solution of the utility model is as follows: a kind of hold down gag that is used to examine the air cleaner filtrator, comprise the fastening screw that is arranged on filtrator one side, by being threaded, the end that fastening screw is positioned at the Rose Box outside is provided with and holds out against handle between fastening screw and the Rose Box.
The aforesaid hold down gag that is used to examine the air cleaner filtrator, wherein, an end that contacts with filtrator at fastening screw is provided with and holds out against screw cap.
The aforesaid hold down gag that is used to examine the air cleaner filtrator wherein, is provided with sealing strip between filtrator and air port framework.
The utility model compresses the cam drive frame-type of original equipment middle filtrator holding device, be improved to the filtrator outdoor handle and regulate compressing of four screw rods, the structure of hold down gag has been simplified in this improvement, saved the manufacturing materials of hold down gag, it is convenient to make filtrator compress adjusting again, and the filtrator sealing is tightr.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1. air port framework 2. filtrators 3. sealing strips 4. hold out against handle 5. fastening screws 6. and hold out against screw cap 7. Rose Boxes
Embodiment
As shown in Figure 1, the hold down gag that is used to examine the air cleaner filtrator comprises the fastening screw 5 that is arranged on filtrator 2 one sides, be symmetrical arranged four fastening screws 5 in the present embodiment altogether, by being threaded, the end that fastening screw 5 is positioned at Rose Box 7 outsides is provided with and holds out against handle 4 between fastening screw 5 and the Rose Box 7.An end that contacts with filtrator 2 at fastening screw 5 is welded with and holds out against screw cap 6, to increase the contact area with filtrator 2.Be provided with sealing strip 3 between filtrator 2 and air port framework 1, filtrator 2 is glued together with sealing strip 3.
The manual adjustments Rose Box outside hold out against handle 4, fastening screw 5 drives and holds out against screw cap 6 pushing filtrators 2 to left movement, and sealing strip 3 distortion are compressed, and forms the sealing fully of filtrator 2 and air port framework 1.The structure of hold down gag has been simplified in this improvement, has saved the manufacturing materials of hold down gag, and it is convenient to make filtrator compress adjusting again, and the filtrator sealing is tightr.
Claims (3)
