Description
?
Technical field
The present invention relates to diesel exhaust clarifier carrier and apply back through-hole rate detection range, be specifically related to the device that a kind of high energy source of parallel light detects the ceramic monolith through-hole rate.
Background technology
, diesel engine relied on its good dynamic property, economy and permanance to be widely used in various propulsion system, boats and ships and vehicle since coming out; So far it is still the highest Thermal Motor of the thermal efficiency; The diesel vehicle growth momentum is swift and violent, and China's estimation diesel vehicle in 2010 recoverable amount reaches 1,200 ten thousand.
Along with the increase of diesel engine quantity and the enhancing of people's environmental consciousness; Diesel engine becomes increasingly conspicuous to the pollution problem of air; Principal ingredient in the diesel engine vent gas and being distributed as: water vapor 2.60%;
7.1%;
15%;
75.21%; Other micro constitutents comprise that particulate matter (PM) accounts for 0.09%; And
; Not combustion
,
,
; Sulfate; Aldehyde and ammonia etc., wherein particulate matter mainly comprises hard carbon (soot), or be called can not dissolve the part (insol or IOF), liquid phase hydrocarbon (HC); Or be called solubilized organic principle (SOF) or volatilizable organic principle (VOF) and adsorb
and the sulfate on it on a small quantity; People think that at first diesel particulates only influences visibility, along with deepening continuously of research; Its harmfulness is understood by people gradually; Some researchs have confirmed that exhaust gas particulate can cause chronic disease, the evidence of EPA (EPA), and SOF has mutagenesis; Its component be carcinogen more than 90%; Feel that the particle diameter of most of exhaust gas particulates between 0.01 ~ 1.0 μ m, can be suspended in the atmosphere for a long time, be easy to get into alveolar and deposit through respiratory system; Than small particle even can get in the blood, very big to the threat of health.Therefore the domestic existing diesel vehicle overwhelming majority has installed exhaust purifier of diesel engine; Its structure is that the carrier that contains catalyzer is installed in the metal cylinder; Play filtration and oxidation and remove the volatilizable organism (SOF) in the particulate matter, reduce the discharging effect of particulate matter (PM); In the exhaust purifier of diesel engine production run, the carrier through-hole rate after the coating is very important, and through-hole rate is too low, and the quilt that can influence system is pressed, and more can influence the quality and the catalytic efficiency of our product.It is just unrealistic to think with the naked eye to go to observe the through hole situation intuitively, so we have invented the device that detects the ceramic monolith through-hole rate with the high energy source of parallel light.
Summary of the invention:
For solving the problem that prior art exists, the invention provides the device that a kind of high energy source of parallel light detects the ceramic monolith through-hole rate, adopt pneumatic gripping device, source of parallel light image system images acquired can let the people detect the through hole situation more intuitively.
The technical scheme that the present invention adopts:
A kind of high energy source of parallel light detects the device of ceramic monolith through-hole rate, it is characterized in that: include clamping device, imaging system and light source; Described imaging system includes trestle table, imaging screen, camera, display screen; The right side of said trestle table is a light source, and the left side is an imaging screen, and the left side of described imaging screen is a camera, and said display location is passed through between camera and the display screen to be electrically connected in camera the place ahead.
Described imaging screen is a frosted glass.
Described clamping device is made up of the air-actuated jaw and the full-automatic mechanical arm of force.
Described light source is a red laser.
Our ceramic monolith mainly is cellular, and same size carrier endoporus pore size is identical, and all parallel; And human eye is to disperse light source, so can only see the hole of part, is that source of parallel light is a laser beam and we adopt; Laser frequency is the highest, and wavelength is also the shortest, can see through the carrier endoporus fully; Hole wall also can block light beam; The image of carrier endoporus and hole wall can be apparent on the collection plate like this, can see the influence of collection more intuitively for eyes, and the laser that we send source of parallel light is designed to red light.
Advantage of the present invention:
Advantage of the present invention is for grasping carrier with the mechanical arm of force, and it is more accurate to let carrier locate, and the adding of source of parallel light, and let us detects through-hole rate more intuitively, and keeps in repair more conveniently, and security performance is more reliable.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
Referring to Fig. 1, a kind of high energy source of parallel light detects the device of ceramic monolith through-hole rate, includes clamping device 7; Imaging system and light source 1, imaging system includes trestle table 6, and the right side of trestle table 6 is a light source 1; The left side is an imaging screen imaging screen 3, and the left side of imaging screen 3 is a camera 4, and display screen 5 is positioned at camera 4 the place aheads; Through being electrically connected, clamping device 7 is made up of the air-actuated jaw 8 and the full-automatic mechanical arm of force 9 between camera 4 and the display screen 5, and imaging screen 3 is a frosted glass.
The course of work is following:
At first air-actuated jaw 8 steps up ceramic monolith 2, and the full-automatic mechanical arm of force 9 lies in a horizontal plane in carrier 2 on the trestle table 6, and source of parallel light 1 is opened; Launch collimated laser beam; Collimated laser beam is reflected in the image of carrier endoporus on imaging screen 3 focussing glass through the endoporus of carrier 2, and image collects through high definition pick-up head 4 again; On display 5, show, the through hole situation that the workman just can be through the image detection carrier on the visual inspection display 5.
