Description
Technical field
The utility model belongs to air filter unit technical field, is related to a kind of heated type self-purging air filter.
Background technique
Automobile bearing pneumatic measuring system requires clean gas source, and the filter bought on the market is losing filtering function
Can after need replacing, increase cost and delay production.
Summary of the invention
The purpose of this utility model is to provide a kind of heated type self-purging air filters, and can reach in filter makes
After the upper limit, automated cleaning is carried out using resistance heating principle.
According to technical solution provided by the utility model: a kind of heated type self-purging air filter, including sealing drum
Power switch is arranged on the sealed cylinder in body, and the sealed cylinder top is equipped with seal cover board, the sealed cylinder
Lower part is provided with seal base, and it is feculence box, the sealed cylinder below the sewage draining exit that the seal base, which is provided with sewage draining exit,
Middle installation metal filter screen, the metal filter screen connect the power switch electric wire positive and negative anodes, the metal filter screen top
Color sensor is set, and the sealed cylinder is divided into upper cavity and lower chamber by the metal filter screen, the lower chamber
Side is provided with air inlet, and the side of the upper cavity is provided with gas outlet, and the color sensor passes through described in electric wire connection
Power switch.
Exhaust safety valve and air gauge are installed on the seal cover board as a further improvement of the utility model,.
The seal base is V-type as a further improvement of the utility model,.
The utility model compared with prior art, has the advantages that
1, the utility model structure is simple, occupies little space；The impurity in gas source can be filtered out, can be provided for equipment clean
Net gas source keeps measuring system stable and reliable in work.
2, for the utility model after impurity reaches a certain amount of in metal filter screen, color sensor, which can be triggered, utilizes resistance
Principle of heating carries out heating cleaning to metal filter screen.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is further described with reference to the accompanying drawing.
In Fig. 1, including sealed cylinder 1, seal cover board 2, seal base 3, metal filter screen 6, upper cavity 7, lower chamber 8,
Air inlet 9, gas outlet 11, exhaust safety valve 12, air gauge 13, color sensor 14, sewage draining exit 16, feculence box 17 etc..
As shown in Figure 1, the utility model is a kind of heated type self-purging air filter, including sealed cylinder 1, it is close
Power switch is set on sealed tube body 1, and 1 top of sealed cylinder is equipped with seal cover board 2, and 1 lower part of sealed cylinder is provided with close
Back cover plate 3.Seal base 3 is V-shaped, and centre is provided with sewage draining exit 16, installs feculence box 17 below sewage draining exit 16.In sealed cylinder 1
Metal filter screen 6 is installed, metal filter screen 6 connects power switch electric wire positive and negative anodes.Metal filter screen 6 is closely golden by high quality
Category is made, and can remove the finely ground particles in air.Color sensor 14, color sensor 14 are set above metal filter screen 6
LX-101 type is produced for Panasonic.1 space of sealed cylinder is divided into upper cavity 7 and lower chamber 8 by metal filter screen 6, lower chamber 8
Side is provided with air inlet 9.The side of upper cavity 7 is provided with gas outlet 11.Color sensor 14 is connected by electric wire and is powered
Switch.Exhaust safety valve 12 and air gauge 13 are installed on seal cover board 2.
The course of work of the utility model is as follows: gas source passes through air inlet 11 first and enters lower chamber 8, flows then up
By metal filter screen 6, metal filter screen 6 removes the impurity in air, is discharged finally by gas outlet 11 and mentions for measuring system
Air supply source.After metal filter screen 6 is polluted by the impurity in air, color gradually fades to the face set in color sensor 14
After color, color sensor 14 sends a signal to power switch, and power switch heats metal filter screen 6 after being powered, and makes metal mistake
Impurity on strainer 6 is thermally decomposed, and the impurity after decomposition drops down on seal base 3, is fallen into along the inclined-plane of seal base 3 to storage
Dirty box 17.Air gauge 13 can constantly observe the barometric information in sealed cylinder 1, if air pressure is excessive or is abnormal, can pass through
Extra gas is discharged exhaust safety valve 12.The color threshold set in color sensor 14 can according to need the matter of gas
Amount grade is adjusted.
