Description
Technical field
The present invention relates to the fume respirator in fire-fighting, is filled more particularly, to the filtering on a kind of fume respirator
Put.
Background technology
Think of danger in times of safety, must not in building and shelter, during the configuration of some saving oneself equipment in today of increasingly urbanization
Can be less.And very when a fire, the quality and function of saving oneself equipment directly affect the chances of survival of personnel.Filtering
The self-rescue apparatus of formula is more conventional in numerous lifesaving appliances, can completely cut off most flue gas and poison to a certain extent
Gas.But the filter of existing fume respirator typically the filter layer both sides of containing medicines it is each fix one piece it is with holes
Filter plate, it is used as gas passage, problems with is present.The gas passage area of respirator is small so that gas exchange is small, breathing
It is not smooth；Gas passage area is small, absorbs flue gas when moisture or use are absorbed during storage, all easily causes gas passage to block.
Such as Chinese patent Authorization Notice No.：CN102614599A, the authorized announcement date 2012 year 08 month patent document of 01 day
In, a kind of canister of filtering respiratory protective devise for self-rescue from fire, including tank body are disclosed, tank body is provided with air inlet and air entry, tank
It is activated carbon fiber layers to be provided with filter poison oxidant layer and drying layer, drying layer in vivo.Canister active carbon fibre disclosed in the patent
Dimension substitutes lithium bromide drier as Vapor adsorption material, can fully ensure that the adsorption rate of steam, will not produce lithium bromide drying
Potential safety hazard caused by agent, and filter toxic effect fruit is enhanced, alleviate weight.But the canister equally exists gas passage face
Product is small so that gas exchange is small, unsmooth breath；Gas passage area is small, absorbs flue gas when moisture or use are absorbed during storage,
The problem of all easily causing gas passage to block.
The content of the invention
The present invention is that gas passage area is small not in order to overcome general fume respirator filter plate with holes to fix medicine
Foot, there is provided the filter on a kind of more smoothly fume respirator of gas exchanges.
To achieve these goals, the present invention uses following technical scheme：
Filter on a kind of fume respirator of the present invention, including circular tank body and circular lid, tank body
Be equipped with passage on lid, is provided with filter layer in tank body, the tank base radially inside provided with some first
Support rib, tank body top is opening, and the lid is radially inside provided with some the second support ribs；Among the filter layer
For the adsorption layer of activated carbon, respectively there is a coating adsorption layer both sides.
It is different that the present invention and prior art with filter plate with holes fix the filter layer containing medicine, it is of the invention tank base with
The first support rib and the second support rib of design protrusion on the inside of lid, clamp the both sides of filter layer respectively, and air enters from passage
It is internal in entirely filtering layer plane, increase along the passage dispersed throughout between the first support rib or the second support rib after entering in tank body
The attaching space of medicament and extraneous air.
Preferably, the bottom of the tank body is the circle end socket of evagination, the passage on tank body is located at the centre of circle end socket；
Lid is the circle end socket of evagination, and the passage on lid is located at the centre of circle end socket.The circle end socket of evagination causes filter layer and tank
Space increase between body bottom or lid, increase the disposable saturation of air of tank interior.
Preferably, the first support rib equidistantly distributed on tank body, the second support rib equidistantly distributed on lid.Side
Just machine Array Design and processing.
Preferably, it is long first support rib to have six equidistant first support ribs in tank body, six long first support
Rib is intersected on tank body axis, and other first support ribs in tank body are short first support rib, and short first support rib extends to
Passage edge；It is long second support rib to have six equidistant second support ribs in lid, and six long second support rib intersects
In on lid axis, other second support ribs in lid are short second support rib, and short second support rib extends to passage
Edge.Because the presence of passage, all support ribs intersect, and can reduce the area of passage, influence gas exchange.But institute
Some support ribs are all non-intersect and unfavorable, can cause passage and filtering interlayer unbraced structure, and filter layer is squeezed
Reason, it is easily damaged here to reveal medicine.So six long support ribs of design.
Preferably, the tank body and lid are flame-retardant plastic material, tank body and lid are provided with fluorescent coating.It is high
Solar heat protection under warm environment；Under smoky condition or dim light environment, visually, it is easy to be found by rescue worker.
Preferably, the coating is the mixture of aloe gel and sodium carbonate.Aloe is in faintly acid in itself, aloe gel
Combined with sodium carbonate so that coating is alkalescence, can neutralize the acid toxic gas such as hydrogen cyanide caused by building burning.And
And aloe gel is natural prodcuts, it is placed on the outside of whole filter layer, contact human body skin is nontoxic, soft to wearer, moreover it is possible to anti-
Only the peculiar smell in filter layer is directly smelt by wearer.
Preferably, the ratio of aloe gel and sodium carbonate is in coating（6：4）~（8：2）.
Preferably, projection one encloses flange on lid, lid is nested into the opening of tank body.Flange is embedding as lid
Enter limiting plate during tank body, yardstick is provided for lid insert depth, prevent from being embedded in too deep, support rib extruding filter layer so that medicine
Product outer filter paper crushes；Or insert depth is inadequate, support rib is not played a supporting role, filter layer activity.
Preferably, lid and the threaded connection of tank body opening.
Preferably, lid and the sealing of tank body opening are connected.
The present invention is different with existing apparatus, and the device of prior art is mainly by two parts identical stainless steel cylinder structure
Into a cylinder loads onto filter plate after medicament is loaded, and cylinder shrinks by punch press punching press, directly blocks filter plate, another cylinder dress
Upper sealing ring, punching press completion assembling again after two cylinders combine.So being not easy to dismantle, medicine is changed.It is of the invention practical nested
The assembling of formula, convenient disassembly.
The present invention has the advantages that：Air is after passage enters in tank body, along the first support rib or second
The passage dispersed throughout supportted between rib is entirely filtering layer plane, increases the attaching space of internal medicament and extraneous air so that gas
Body exchanges more smoothly.Acidity poison gas in the alkaline coating of aloe gel and during fire, and cause wearer comfort, smell
Peculiar smell is lighter.
