Description
Technical field
The invention belongs to Environmental Safety facility technology field, be specifically related to a kind of dust concentration pick-up unit, use the quality of understanding air for the airborne dust concentration to industrial and mineral operation place detects
Background technology
For the industry that easily produces in process of production dust for example colliery, cement products industry, textile industry, food-processing industry (such as flour mill) and medication chemistry industry etc.; usually need to rely on monitoring device of powder-like waste that the air of operation field is monitored; in order to take corresponding Disposal Measures; use on the one hand the healthy of protection occupational population, Accident prevention occurs on the other hand.That occured and all be tending towards saturated because of airborne dust concentration and meet due to static and/or the naked light by flour mill's blast of media report, the blast of numb cotton mill and explosion of coal mines accident etc. in the past.Again, the worker's of above-mentioned industry occupational illness also causes because of the dust infringement that is subjected to for a long time the operation place.In recent years, along with people to carry out production strictly in line with rules and regulations, cleaning operation, safe construction consciousness and improving constantly people-based concept understanding, thereby not only formulate the system of carrying out dust monitoring for the operation place in aforementioned industry, and for operation field has been equipped with the dust concentration monitoring device, this is comparatively general in the colliery.
Technical information about the dust concentration pick-up unit can be seen in disclosed Chinese patent literature, " direct-reading dust concentration detector " recommended such as invention patent mandate notification number CN101603912B remedied the CN2799901Y(Bidirectional diaphragm pump), the CN2800261Y(dust sampling head) and the CN2076235U(essential safety type dust sampler with two pump for coal mine) shortcoming (can referring to 2 page of the 2nd row of the 1st page of final stage to the of instructions of CN101603912B), and objectively embodied the 4th page of the 2nd section alleged technique effect of instructions, yet, because it is by the dust level that is adsorbed on the filter paper infrared signal that the impact of the luminous quantity of signal projector emission receives signal receiver to be changed, and then be that airborne dust concentration numerical value is showing screen display by the value that signal processing apparatus will be determined through converting, therefore be difficult to make structure to satisfy to the terse requirement of people's expectation.
" sensor of dust concentration " typical as practical new patent Granted publication CN200972448Y provides, by shell, dust sampling head, dust room, blower fan and photoelectricity receiving device form, dust room is established in the enclosure, dust sampling head is arranged on a side of dust seat, assembling is at the opposite side of dust room, the photoelectricity receiving device is arranged on the top of dust room, though this patent scheme has the strong point of eight aspects of its Instructions Page 3 conclusion, but objectively there is following shortcoming: one, because blower fan and dust sampling head are in respectively the both sides of dust room and are the diagonal angle setting, therefore in order to guarantee flowing of dust laden air, the power of blower fan is relatively large, thereby is unfavorable for energy-conservation; Its two because dust room is the body structure of a rectangle, adds fan and sampling head and be the diagonal angle setting, so easy productive set trifle in the world in the dust room, if the trifle in the world that will remove in the dust room is then very difficult; They are three years old, the patent scheme has perhaps been considered and has been avoided the trifle in the world productive set in dust room, thereby in dust room and at the air inlet position near blower fan, be provided with a dividing plate, yet there is the shortcoming of attending to one thing and lose sight of another in arranging of dividing plate, this is so-called Gu to play and stops or reduce trifle in the world and fall the effect of gathering in dust room, that then can increase resistance to blower fan so-called mistake, makes the increase of output power of blower fan, wastes energy; They are four years old, because the structure of dust room is lost rationally, therefore need to be remedied by the supporting light absorbing canister that has light to fall into, particularly, process reflected light by light absorbing canister, because if there is reflected light, can produce aforesaid photoelectric receiving arrangement so and disturb, cause measurement data higher, be not inconsistent with the truth of dust concentration, it is inaccurate finally to cause dust concentration to detect.Again, therefore " sensor of dust concentration " that utility model patent Granted publication CN201177594Y introduces exist similar shortcoming because dust room's (patent claims the darkroom) structure is tending towards identical with aforesaid CN200972448Y.
Shortcoming in view of above-mentioned prior art exists is necessary to be improved, and for this reason, the applicant has done useful design, and technical scheme described below produces under this background
