Description
Technical field
The utility model relates to a kind of atmosphere particulate matter cutter, especially a kind of atmosphere particulate matter cutter preventing foreign matter from entering.
Background technology
Along with the requirement of Environmental protection is more and more higher, also more and more higher to the requirement of air quality.So also just correspondingly improve the monitoring accuracy of atmosphere particle concentration, and atmosphere particulate matter cutter is one of indispensable main device.Atmosphere particulate matter cutter is under the effect of aspiration pump, Atmospheric particulates enter by atmospheric connection the inner chamber that cutter arrives taper chorista with air, due to the special construction of cutter, Atmospheric particulates are divided into two movement locus herein: a track namely under screw is the particle movement locus that aerodynamic diameter is larger---major diameter particle movement locus; Another movement locus is upwards then the particle movement locus that aerodynamic diameter is less than aforementioned diameter, referred to herein as small diameter particles thing movement locus, and the particle of this direction motion we will gather and carry out quality depth analysis just.Existing atmosphere particulate matter cutter uses for a long time may have foreign matter to enter in cutter, produces certain impact to measurement data, thus cannot ensure monitoring accuracy.
Utility model content
The purpose of this utility model is: provide a kind of atmosphere particulate matter cutter preventing foreign matter from entering, solve existing atmosphere particulate matter cutter to use for a long time foreign matter may be had to enter in cutter, certain impact is produced on measurement data, thus the problem of monitoring accuracy cannot be ensured.
The technical solution adopted in the utility model is: a kind of atmosphere particulate matter cutter preventing foreign matter from entering, comprise the separation cavity being provided with intake elbow, with the dust storage chamber being separated cavity lower end and connecting, be plugged in the bend pipe of giving vent to anger be separated in cavity, intake elbow is provided with protective device, and protective device comprises reducing sleeve, protective cover, screen pack, and reducing sleeve is fixed in one end of protective cover, protective cover is connected with one end of intake elbow by reducing sleeve, and screen pack is positioned at protective cover one end away from reducing sleeve.
As further improvement of the utility model, protective device also comprises locking end cap, and end cap is detachable is fixed on protective cover one end near screen pack in locking.
As further improvement of the utility model, protective cover is tapered, its wide mouth part is air intake end, and locking end cap is positioned at wide mouth part, reducing sleeve is positioned at slot end.
The beneficial effects of the utility model are: after have employed this structure, can effectively prevent the foreign matter such as willow catkins flying in the air, spider silk from entering atmosphere particulate matter cutter, thus improve the cutter efficiency and precision of Atmospheric particulates, obtain monitoring instrument and atmosphere particle monitoring data more accurately can be provided.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Shown in figure: 1 gives vent to anger bend pipe, 2 are separated cavitys, 3 intake elbows, 4 dust storage chambers, 5 reducing sleeves, 6 protective covers, 7 screen packs, 8 locking end caps.
Embodiment
Below the utility model is described further.
As shown in Figure 1, the utility model embodiment: a kind of atmosphere particulate matter cutter preventing foreign matter from entering, comprise the separation cavity 2 being provided with intake elbow 3, with the dust storage chamber 4 being separated cavity 2 lower end and connecting, be plugged in the bend pipe 1 of giving vent to anger be separated in cavity 2, intake elbow 3 is provided with protective device, protective device comprises reducing sleeve 5, protective cover 6, screen pack 7, reducing sleeve 5 is fixed in one end of protective cover 6, protective cover 6 is connected by reducing sleeve one end with intake elbow 3, the detachable detachable of screen pack 7 is fixed on protective cover 6 one end away from reducing sleeve 5, protective device also comprises locking end cap 8, end cap 8 is detachable is fixed on protective cover 6 one end near screen pack 7 in locking, protective cover 6 is tapered, its wide mouth part is air intake end, locking end cap 8 is positioned at wide mouth part, reducing sleeve 5 is positioned at slot end.
In the utility model embodiment, intake elbow 3 is provided with protective device, protective device comprises reducing sleeve 5, protective cover 6, screen pack 7, because screen pack 7 can play filtration, stop the effect of foreign matter, thus can effectively prevent the foreign matter such as willow catkins flying in the air, spider silk from entering atmosphere particulate matter cutter, thus improve the cutter efficiency and precision of Atmospheric particulates, obtain monitoring instrument and atmosphere particle monitoring data more accurately can be provided.Screen pack 7 both can be fixedly connected with away from reducing sleeve 5 inwall of one end of reducing sleeve 5 is detachable with protective cover 6, also be fixedly connected with away from the end of one end of reducing sleeve 5 is detachable with protective cover 6, when the locking end cap 8 arranged, (structure of this locking end cap 8 can be that one end central authorities are provided with a larger through hole, or one end is provided with several small through hole, or be only to prevent screen pack 7 surface area dust when not using can gas circuit sealing lid, when at one end central authorities are provided with a larger through hole, a circle groove can also be arranged at through-hole side wall to be used for placing screen pack 7), screen pack 7 both can be placed on that protective cover 6 makes its end cap 8 that is locked stop to prevent it from dropping away from one end of reducing sleeve 5 can (because protective cover 6 is tapered, screen pack is in or end face size adaptation inner near wide mouth part place and size and protective cover, therefore when bleeding with air pump, the dynamics of if desired bleeding is less, screen pack can be stopped by the inwall of protective cover 6, need not worry that screen pack 7 can be sucked away), also with protective cover 6 or can lock that end cap 8 is detachably detachable to be fixedly connected with.During use, under the effect of aspiration pump, Atmospheric particulates enter foreign matter in cutter with air by bend pipe of giving vent to anger to be stopped by protective device, thus can effectively prevent the foreign matter such as willow catkins flying in the air, spider silk from entering atmosphere particulate matter cutter, thus improve the cutter efficiency and precision of Atmospheric particulates, obtain monitoring instrument and atmosphere particle monitoring data more accurately can be provided.
Those skilled in the art should know; protection scheme of the present utility model is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to the utility model spirit, the various conversion that the utility model carries out all are dropped in protection domain of the present utility model.
