Description
Technical field
The utility model belongs to filter technology field, in particular to a kind of novel precision filter.
Background technology
Accurate filter is a kind of advanced treating and separation equipment by compressed gas, be one kind dedicated for filtered compressed
The device of solid suspended particles etc. in gas may filter that the solid particulate matter of grain size in sample in 0.01-l0um, after filtering
Compressed gas can be for the process equipment of follow-up higher processing requirement：Be suitble to thermal power plant instrument and meter, electronics, casting, papermaking,
The application of the every profession and trades such as metallurgy, food, medicine production.
It is well known that under any operating mode, the compressed air of unprocessed mistake contains many impurity, such as：Water, rust, particle
Dust and oil.If not removing these impurity, they will cause additional production loss, product quality problem and high maintenance into
This.Compressed air is the main security energy of large-scale industrial production, and it is exactly to reduce production cost to improve compressed air quality,
So will be handled using accurate filter, cost is reduced.
Precision filter of compressed air on the market is threadedly coupled for two-part now, and is cylinder, because compression is empty
The filter core of air filter and built-in water trap belong to consumptive material, it is necessary to regularly replace, maintain, and so design and cause replacing, protecting
There are problems that two when supporting：
1st, filter core needs are replaced to unscrew screw thread, and cylinder is inconvenient to exert oneself, it is necessary to dedicated Chain wrench, Duo Shuo little
Company is not equipped with such instrument, and so replacing filter core will seem cumbersome.
2nd, automatic water trap built in replacing, built-in automatic water trap is mounted in the bottom of column barrel, because using and designing
Reason, base apertures generally can be smaller, and column barrel is elongated shape, and hand cannot fully extend to bottom, cause built in replacement
Automatic water trap is more time-consuming.
Utility model content
To solve above-mentioned existing problem, the utility model provides a kind of of simple structure and low cost, easy to disassemble, close
The novel precision filter that the good, filter efficiency of envelope property is obviously improved.
The technical solution that the utility model is taken is as follows：The utility model accurate filter, including filter upper end cover, mistake
Filter middle cylinder and filter bottom end cover, filter middle cylinder are arranged between filter upper end cover and filter bottom end cover,
Filtration core, circular support frame, automatic water trap, automatic water trap fixing nut are equipped in filter middle cylinder, on filter
End cap is equipped with filtering air inlet, filter outlet mouth and annular engaging groove, the upper end of filtration core and filtering air inlet
Connection, filtration core are connected on annular engaging groove, and circular support is set up between filtration core and filter bottom end cover, circle branch
Support is equipped with Manual water drainage device through hole, and automatic water trap is arranged in circular support frame, and automatic water trap includes floating ball and draining
Device, floating ball are arranged on water trap, and water trap is internally provided with drainage channel, and water trap external screw thread body, draining are equipped with below water trap
Device external screw thread body is fixed on by automatic water trap fixing nut on filter bottom end cover after passing through filter bottom end cover.
Further, the both ends of the filter middle cylinder are equipped with cylinder internal thread, filter upper end cover and filter
Bottom end cover is equipped with and the matched end cap through hole of cylinder internal thread.Filter middle cylinder is connected through a screw thread filter upper end
Lid and filter bottom end cover.
Further, sealing ring is equipped between the filter upper end cover and filtration core, seal is good.
Further, the filter bottom end cover is equipped with and the matched O shapes slot of circular support frame.
What the utility model obtained using the above structure has the beneficial effect that：The letter of this programme novel precision filter structure
Single, design is reasonable, of low cost, easy to operate, when replacing filter core common allen wrench is only needed filter can be dismantled,
The instrument of specialty is not required；Built in replacement during water trap, also lower part need to only be opened with allen wrench, it is so built-in from
Dynamic water trap is convenient for changing above platform；Bottom has filled cylindrical support frame, first, filter core can be supported, allows filter core
It will not be poorly sealed with upper part under the effect of the pressure or separates；Second is that cylindrical support frame occupies certain space, and
There is Manual water drainage device through hole below this filter, there is filter outlet mouth above, such filter core filters out the condensed water come in cylinder
Height inside and outside shape branch palm frame is the same, and cylindrical support frame alsies occupy certain space, the height of such condensate liquid in itself
Degree will be more many than being higher by when no placement cylindrical support frame；It, can be with because the floating ball principle of built-in automatic water trap
Than it is no placement cylindrical support frame when earlier floating ball jack-up come, in order to more in time condensate liquid discharge filter
Outside prevents the secondary filter efficiency for entering compressed air pipe, can improving accurate filter of condensate liquid.
