Description
Technical field
A kind of gas-filtering device is the utility model is related to, more particularly to a kind of self arrangement compressed-air filter.
Background technology
In pneumatic element field, compressed-air filter is a kind of moisture filter by compressed air and the gas discharged
Source handles original paper, can prevent the gentle hole portion part spool corrosion of inner-walls of duct.
Authorization Notice No. is that the Chinese patent of CN202893105U discloses a kind of pipeline air filter, including valve body,
Base and cup, the base upper end are connected with valve body, and base lower end is connected with cup, and the cup bottom is equipped with draught engine
Structure, the base is interior formed with cavity, and the cavity is interior to be equipped with ring-like filter core.
When crossing air filtering, the impurity in air is retained and assembled in cup the filter by ring-like filter core, when
Impurity in cup opens drain valve after reaching a certain amount of and ponding is discharged.And when it is applied in moist environment,
Moisture in cup can gather faster, for this reason, it may be necessary to frequently open and close drainage mechanism draining, not filtered with preventing water level from rising to
Core, operation are inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of self arrangement compressed-air filter, which solves existing compressed air
Need frequently to open and close drainage mechanism draining when filter is applied in wet environment to prevent ponding from not having the problem of filtration core.
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of self arrangement compressed-air filter, including valve body, be connected to the cup of valve body lower portion, be threaded through cup bottom
Drainage mechanism and floatation element, the drainage mechanism includes drainage seat and be plugged in drainage seat can be axial along drainage seat
The drain plug of lifting, the floatation element include one end be connected to drain plug upper surface rope and with the rope other end
The kickboard of connection, the kickboard are arranged on the bottom of cup and the inner cavity of cup are divided into epicoele and is connected down with epicoele
Chamber.
Using the above scheme, toward after being passed through air in the cup of filter, the air pressure in cup is more than extraneous atmospheric pressure,
Drain plug along the axial decline of drainage seat and is entrenched in drainage seat by the air pressure in cup, and the bottom of cup is sealed
Close, easy to the filtering of air；When the ponding filtered out in cup reaches setting water level, the kickboard in floatation element is with water level
Rising and to floating, then drive the rope being connected between kickboard and drain plug by drain plug toward away from drainage seat side
To drawing, without people, the valve of air-flow or opening drainage mechanism carries out draining in order to control, to reach the self-draining of filter；Treat
Water level decreasing, drain plug lose the pulling force of kickboard, and drain plug is chimeric again with drainage seat under the action of air pressure in cup,
So that the ponding in cup always below sets water level, and then prevent ponding from not having filtration core, reduce the waste of human resources, make
Obtaining filter persistently can filter air, add the work efficiency of filter.
More preferably：Some through holes are uniformly provided with the kickboard.
Using the above scheme, the droplet filtered out from air slides along cup inner wall or is directly dripped from the top of cup
Drop down onto in kickboard, the through hole of kickboard is smoothly circulated to the bottom of cup easy to current, this accessibke porosity additionally aid cup epicoele and
Air pressure between cavity of resorption maintains balance.
More preferably：The edge of the kickboard is circumferentially provided with some first card convexs, and the lower part of the cup is set
Have for the first spacing card slot of the first card convex.
Using the above scheme, when in cup without ponding, kickboard is limited in the lower part of cup, prevents kickboard with air-flow
And swing.
More preferably：The upper surface of the drain plug is provided with the first link, and the lower face of the kickboard is set
There is the second link, the rope ends are removably attachable on the first link and the second link successively.
Using the above scheme, floatation element can be mounted and dismounted as needed, easy to the cleaning inside cup, structure
Simply, cost is relatively low, easy to widely be promoted.
More preferably：The upper surface of the drainage seat is located at the lowest point of cup inner wall.
Using the above scheme, easy to be drained completely in the ponding of cup congregate, ponding is avoided to remain in cup
And a large amount of bacteriums are grown, ensure in filter drying internal when not in use and clean and tidy.
More preferably：The drain plug includes above being placed in the limiting section of drainage seat, is connected to limiting section lower end
The outer sheath of supporting part and the Drainage Division for being connected to supporting part lower end, the supporting part and Drainage Division is equipped with spring；The row
The upper end of water seat offers the limiting slot for limiting section clamping, and abutment ring is provided with the inner wall of its underpart；The spring it is upper

Line fixes finite place piece, and the upper surface of the locating part is abutted with the lower face of abutment ring.
Using the above scheme, spring provides restoring force for drain plug, using simple structure cause drain plug along
Drainage seat axially lifts, and reduces the cost of production；Carry out of the locating part to drain valve is spacing, prevents drain plug from being axially disengaging
Go out drainage seat.
More preferably：The central shaft of the upper surface of the abutment ring towards drainage seat tilts down setting, the row
Water valve core is provided with some osculums in abutment ring inclined upward, and the other end of the osculum runs through the bottom of drain plug.
Using the above scheme, abutment ring and being obliquely installed for osculum play the guiding role for the discharge of ponding, accelerate product
The speed of water discharge, increases displacement of the filter in the water discharge time of setting, and then adds the work effect of filter
Rate.
More preferably：Filter screen is connected with the middle part of the cup, the center of the filter screen offers venthole.
Using the above scheme, the air being passed through in cup is filtered the solid particle in air by filter screen, resistance
Only solid particle falls within the bottom of cup, and drain plug is caused to block, adds the service life of filter；Venthole
Air pressure easy to the air pressure above filter screen and below filter screen maintains balance.
More preferably：The outer edge of the filter screen is circumferentially provided with some second card convexs, above the cup
The second card slot for the clamping of the second card convex is provided with inner wall.
Using the above scheme, the setting of the second card convex and the second card slot, it is simple in structure, easy to filter screen Fast Installation and
Dismounting.
More preferably：The filter screen is provided with the bulge loop that section is inverted L-shaped straight up at air hole.
Using the above scheme, taking when being installed or removed easy to filter screen, adds the work efficiency of filter screen handling.
In conclusion the utility model has the advantages that：
Pass through the setting of kickboard in floatation element so that the ponding in filter cup can be arranged voluntarily when reaching setting water level
Put, prevent ponding from not having a filtration core and cause filter can not normal operation, reduce artificial monitoring and operation, and then reduce
The waste of human resources；The setting of filter screen intercepts the solid particle in air, prevents the blocking of filtering spool, increase
The service life of filter.
