Abstract
The invention discloses a simple dustproof device for a gas detector. The simple dustproof device comprises a shell, a lining and a dustproof gas-permeable membrane, and is characterized in that the lining is arranged inside the shell, the dustproof gas-permeable membrane is arranged between the shell and the lining, and the shell and the lining are combined and connected via a bolt and a gasket. Dust can be effectively prevented from entering inside, and the simple dustproof device has the advantages of high efficiency, low cost and no need of powering off.
Description
Technical field
the present invention relates to a kind of dust guard, particularly relate to a kind of simple dust preventing device of gas detector.
Background technology
at present in the place of dangerous gas, what people were a large amount of employ this equipment of gas detector monitors gas concentration.Mainly be divided into combustible gas probe or toxic gas detector.Wherein combustible gas probe needs to meet explosion-proof criteria requirement, current combustible gas probe, because it adopts catalytic combustion type gas sensor in a large number, can only make flame-proof type gas detector.In catalytic combustion sensor must be enclosed in by a flame proof cavity.The breathing equipment that can completely cut off explosive flame unofficial biography through sintered metal mesh or metal powder metallurgy sheet etc. is needed with space outerpace gas exchanges.But this device is in the environment that dust is larger, as smelted, mining site etc.Breathing equipment can be caused to block very soon, cause air exchange not smooth, cause sensor failure or the speed of response slack-off.Solve this situation, can only breathing equipment be changed.The place used due to it is generally explosion-proof place, forbids charged uncapping.So can only change equipment being taken away from the scene after device powers down.Such cost is higher, and more time-consuming.Especially during this, detect the scene of causing that can not work occur that danger can not Timeliness coverage.So we need a kind of device only can change it, the blast resistance construction of whole product can not be destroyed.Dust guard is changed easily when not power-off.
current dust guard, structure relative complex.And mostly need professional tool or power-off when replacing.Cause cost higher, and power-off time surrounding environment cause danger.
Summary of the invention
for the problems referred to above, the object of the invention is one can effectively prevent dust from entering inside, and it is low to have efficiency high cost.Do not need the simple dust preventing device of a kind of gas detector of the feature of power-off.
in order to realize object of the present invention, the technical solution adopted in the present invention is: a kind of simple dust preventing device of gas detector, comprises shell, liner, dust-proof air ventilation film; It is characterized in that: described enclosure is provided with liner, between shell and liner, be provided with dust-proof air ventilation film, be connected with spacer for bolt between shell and liner.
described shell is shell with threaded hole.
the invention has the beneficial effects as follows: the present invention can effectively prevent dust from entering inside, and it is low to have efficiency high cost.Do not need the feature of power-off.
Accompanying drawing explanation
fig. 1 is Facad structure schematic diagram of the present invention;
in figure: 1-shell, 2-liner, 3 ~ 5 spacer for bolt combinations, 6-dust-proof air ventilation film.
Embodiment
below in conjunction with accompanying drawing, the present invention is described further.
embodiment one:
a simple dust preventing device for gas detector, comprises shell 1, liner 2, dust-proof air ventilation film 6; It is characterized in that: described shell 1 inside is provided with liner 2, is provided with dust-proof air ventilation film 6 between shell 1 and liner 2, connect with spacer for bolt combination 3 ~ 5 between shell 1 and liner 2.
described shell 1 is shell with threaded hole.
embodiment two:
dust-proof air ventilation film 6 is wrapped in outside liner 2, shell 1 is enclosed within outside dust-proof air ventilation film 6.Be fixed in outside detector sensor cover with spacer for bolt combination 3 ~ 5.Only need to turn on screw when needs cleaning dust, dust-proof air ventilation film 6 is pulled down and carries out clearing up.Can directly install after having cleared up.
Claims (2)
1. a simple dust preventing device for gas detector, comprises shell, liner, dust-proof air ventilation film; It is characterized in that: described enclosure is provided with liner, between shell and liner, be provided with dust-proof air ventilation film, be connected with spacer for bolt between shell and liner.
2. the simple dust preventing device of a kind of gas detector according to claim 1, is characterized in that: described shell is shell with threaded hole.
