Description

Circular filter

Technical field

The utility model relates to air cleaning facility, particularly a kind of circular filter, and the radial seal structure of circular filter and supporting purifier.It is applied to the filtration, purification of the ventilating system of nuclear fuel reprocessing plant and some condition systems that knock off by force.Also be applicable to the occasion of some other this kind equipment of use.

Background technology

Existing air filter unit kind is a lot, and the air cleaner contour structures that uses in ventilating system at present mostly is square greatly.Its sealing is to realize end face seal by eccentric wheel and leading screw hold-down mechanism.

No. 3078650 U.S. Patent Publication a kind of prior art structure of such air cleaner, this air cleaner has a tubular metal housing, this housing has an import, enters for the air of dust-laden.Columnar pleating papery filter element is installed in the housing.Clean air outlet is communicated with the inner chamber of pleating papery filter element.Provide sealing between pleating papery element and outlet, like this, the gas that contains dust will be forced through the paper medium on the filter, before air-flow leaves filter dust be removed from air-flow.In this patent, the sealing between filter element and the outlet is to provide by the liner that is fixed on the filter element.The end wall of liner and tubular shell is bonding, and filter element is by a clip and relevant screw nut assembly stationary positioned.

No. 4720292 U.S. Patent Publication one type the prior art structure of cylindrical air filter.In its preferred embodiment, the housing of air cleaner is that plastics are made, and columnar pleating papery filter element is installed in the housing.Pleating papery element have one with the openend of air communication.The annular end cap of openend is to make with elastomeric material, and it is quite soft.The air filtration element is installed on the air outlet slit pipe.Provide sealing by end cap and pipe-type outlet components bonding.

95191278.X number Patent Office of People's Republic of China (PRC) patent has been announced a kind of air cleaner.It is a plastic end cover that is fixed on housing one end with the tubular metal housing and of an air intlet.The other end of housing has a dismountable cover cap sealing.Can block the elastomer of filter element opening end with the tubular portion of plastic end cover moulding together, realize the sealing of filter element and end cap.

03257764.8 number State Intellectual Property Office of the People's Republic of China has announced a kind of air cleaner.The structure that embodiment announces is made up of outside framework, filter core and inner frame.Outside framework and inner frame socket, and with sealed at both ends gluing.Filtrate and demarcation strip are formed filter core, and filter core combines with the sealing of cylindrical shape inner frame.Cylindrical shape outside framework one end is provided with the screw thread that cooperates with outside connector.Its sealing means is end face seal.

Though above-mentioned existing air filter respectively has its characteristics, but still exists unreasonable structure, and is impracticable, or cost is higher, substitute mode is convenient and swift inadequately, has potential safety hazard.

Summary of the invention

The purpose of this utility model is just at existing weak point in the above-mentioned prior art and custom-designed a kind of simple and reasonable, and good seal performance is installed and changed convenient and swiftly, safe and reliable, and the post processing of contaminated useless filter is very simple.

The purpose of this utility model realizes by following scheme: this circular filter comprise the tubular filter element and be installed on tubular filter element two ends on, bottom end cover, filter element is by interior, tubular protection net that the outer wall cover is formed and the filter core that is arranged on therebetween, protection network and filter core combine by fluid sealant and end cap up and down, upper end cover is a disk-shaped structure, bottom end cover is a loop configuration, the annular rubber cushion is fixed on the annular end cap by platen, and the internal diameter of annular rubber cushion is less than the internal diameter of annular end cap, the taper that is connected with purifier is taken over and is directly inserted the filter inner chamber by annular end cap, the dependence taper is taken over, the cooperation of annular rubber cushion and annular end cap realizes the radial seal of filter and purifier, reaches the purpose of circular filter and purifier sealing.

In the utility model, disc-shaped cap is provided with handle, so that grip when changing; Filter core is to roll into cylindrical structure after being folded by filtrate.Between the upper/lower terminal lid, be furnished with many vertical lacing wires, can effectively protect filter core, guarantee that simultaneously two end caps become a firm integral body not by drawing crack along tubular filter element outer wall.Filtrate can be selected glass fibre for use, the also optional material that is suitable for doing filtrate with industrial filter paper etc.

Protection network adopts metal rhombus net to make, and can guarantee the rigidity of filter.

Circular filter of the present utility model mainly is to improve from structure, realizes making under the function prerequisite simple for structure in assurance as far as possible.The filter two ends have an annular end cap and disc-shaped cap respectively.Filtrate is processed into cylindrical shape filter core and protection network one to be reinstated fluid sealant and is fixed in the middle of the two end cap.Evenly arrange lacing wire around the two end cap.Handle is arranged on the disc-shaped cap, use for installation and removal.Disc-shaped cap is fixed an annular rubber cushion with annular platen.The internal diameter of annular rubber cushion is less than the internal diameter of annular end cap.Be designed to the Taper Pipe of certain taper with the adapter on the purifier that filter cooperates, allow the inner ring of Taper Pipe and filter annular end cap cooperate and realize radial seal.

The utility model compared with prior art has following advantage:

1, the filter overall weight is light, and volume is little, and has handle in filter end, and it is easy that the replacing filter is installed, and greatly reduces labor intensity of operating personnel.

2, hermetically-sealed construction is simple and reliable, does not need the independent hold-down mechanism of filter, saves the on-the-spot holdup time of operating personnel greatly.

3, the post processing mode of useless circular filter is very simple, only needs simple forcing press can realize subtracting and holds processing.

4, subtract that to hold the processing ratio big, axial dimension is compressible 2/3, for the post processing of filter has brought convenience and disposal costs to reduce greatly.

5, should realize from inside to outside flowing by the air-flow of circular filter, can make most of harmful substance stay the filter core inside cavity, help reducing the generation secondary pollution.

6, the filter end face is circular, makes its supporting purifier realize that the substitute mode of " bag advances bag and goes out " is safer reliable, simple operation.

7, adopt the radial seal mode, make the installation replacing of filter can adopt mechanized operation, more faster than traditional manually-operated, reliable and safety.

8, adopt Taper Pipe type seal member to substitute traditional eccentric wheel, leading screw and compress mode, more compact structure, easy and simple to handle reliable.

9, on the circular filter structure, realized unique simplest and dependable radial seal.
