Abstract
The utility model relates to a kind of automatic alarm air filters, including sealed cylinder, sealed cylinder top is installed by seal cover board, seal base is arranged in sealed cylinder lower part, spring guide is set on seal base, support spring is arranged outside spring guide, air filter plate is set above support spring, it is positioned proximate to switch below air filter plate, sealed cylinder lower side is provided with air inlet sealed cylinder lower side setting gas outlet.Spring guide is symmetrical arranged on seal base.The accurate filter of the utility model can once filter out impurity, greasy dirt and water in gas source, and clean gas source can be provided for equipment, keeps measuring system stable and reliable in work, close to switch the alarm that be triggered after impurity reaches a certain amount of in air filter plate.
Description
Technical field
The utility model belongs to air filter unit technical field, is related to a kind of automatic alarm air filter.
Background technique
Automobile bearing pneumatic measuring system requires clean gas source, and the filter bought on the market is losing filtering function
After energy can not prompting changing, cause air source quality to decline.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic alarm air filters, can reach SC service ceiling in filter
Go out activating alarm afterwards, user is provided and is replaced.
According to technical solution provided by the utility model: a kind of automatic alarm air filter, including sealed cylinder, institute
Sealed cylinder top installation seal cover board is stated, the sealed cylinder lower part is arranged seal base, is arranged on the seal base
Spring guide, the spring guide are arranged support spring outside, air filter plate, the air are arranged above the support spring
It is positioned proximate to switch below filter plate, the sealed cylinder space is divided into upper cavity and cavity of resorption by the air filter plate
Body, the side of the lower chamber are provided with air inlet, and the side of the upper cavity is provided with gas outlet.
The spring guide is symmetrical arranged on the seal base as a further improvement of the utility model, quantity
It is 2.
The air filter plate outer layer is filter paper as a further improvement of the utility model, and centre is active carbon.
Exhaust safety valve and air gauge are installed on the seal cover board 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；Impurity, greasy dirt and the water in gas source, energy can once be filtered out
Clean gas source is enough provided for equipment, keeps measuring system stable and reliable in work.
2, the utility model is close to switch the alarm that be triggered after impurity reaches a certain amount of in air filter plate.
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, spring guide 4, support spring 5, air mistake
Filter plate 6, filter paper 6-1, active carbon 6-2, upper cavity 7, lower chamber 8, air inlet 9, gas outlet 11, exhaust safety valve 12, air pressure
Table 13, close switch 14 etc..
As shown in Figure 1, the utility model is a kind of automatic alarm air filter, including sealed cylinder 1, sealed cylinder 1
Top is equipped with seal cover board 2, and 1 lower part of sealed cylinder is provided with seal base 3, spring guide 4 is arranged on seal base 3,
Spring guide 4 is symmetrical arranged on seal base 3 in the present embodiment, quantity 2.It is arranged support spring 5 outside spring guide 4,
Air filter plate 6 is set above support spring 5, and support spring 5 is that air filter plate 6 provides support force.Air filter
6 outer layer of plate is filter paper 6-1, and centre is active carbon 6-2.It is positioned proximate to switch 14 below air filter plate 6, connects close to switch 14
Device taking alarm.1 space of sealed cylinder is divided into upper cavity 7 and lower chamber 8 by air filter plate 6, and the side of lower chamber 8 is set
It is equipped with air inlet 9.The side of upper cavity 7 is provided with gas outlet 11.Exhaust safety valve 12 is installed gentle on seal cover board 2
Press table 13.
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 air filter plate 6, filter paper 6-1 removes impurity and greasy dirt, and activated carbon 6-2 filters out the moisture content in gas source, finally by out
The discharge of port 11 provides gas source for measuring system.Weight gradually increases after air filter plate 6 absorbs moisture content and impurity, support
Spring 5 is constantly declined by the gravity of air filter plate 6, after air filter plate 6 declines and triggers close switch 14, triggering
Starting alarm issues alarm after close to switch 14.Air gauge 13 can constantly observe the barometric information in sealed cylinder 1, if gas
It presses through big or is abnormal, extra gas can be discharged by exhaust safety valve 12.
