Abstract
The utility model discloses a device for improving particle detection limit in liquid, including the device main part, the both sides of device main part communicate respectively has first connecting pipe and second connecting pipe, first connecting pipe and second connecting pipe pass through fastening bolt and device main part fixed connection, the middle part of device main part is equipped with first slit, the middle part of second connecting pipe be equipped with with first slit vertically second slit, the outside of second slit is equipped with the image magnification device. The passageway that flows through of liquid and particle is done to the first slit of this a device for improving particle detection limit in liquid use, along the light path direction, enlarge the slit earlier, then a second slit is being place rather than the vertically direction in the position among them, and the lower limit that detects that the hou mian light energy situation of change of second slit can improve the particle detection is surveyed to the image magnification device of deuterogamying, has improved the accuracy that the particle detected.
Description
Technical field
The utility model relates to checkout equipment technical field, is specially a kind of device for improving particulate detection limit in liquid.
Background technology
At present the energy size (light blockage method) of conventional slit class device and shading light detects particle diameter, and the less accuracy of detection of slit is higher in theory, but in slit manufacture craft, have smallest limit in reality, can not meet work requirements during measurement.
Utility model content
The purpose of this utility model is to provide a kind of device for improving particulate detection limit in liquid, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of device for improving particulate detection limit in liquid, comprise apparatus main body, the both sides of described apparatus main body are communicated with the first connecting pipe and the second connecting pipe respectively, described first connecting pipe is fixedly connected with apparatus main body by fastening bolt with the second connecting pipe, the middle part of described apparatus main body is provided with the first slit, the middle part of described second connecting pipe is provided with the second slit with the first slit vertical, the outside of described second slit is provided with image amplifying device, described apparatus main body, first connecting pipe, second connecting pipe, run through between first slit and the second slit and have fluid passage.
Preferably, length, the width of described first slit, be highly respectively 1000 microns, 400 microns, 4000 microns, and the height of described first slit be in fluid passage liquid flow to direction.
Preferably, described second slit width and be highly respectively 400 microns and 200 microns.
Preferably, the junction of described first connecting pipe and the second connecting pipe and apparatus main body is all provided with seal gasket.
Compared with prior art, the beneficial effects of the utility model are: what this device being used for improving particulate detection limit in liquid used the first slit to do liquid and particulate flows through passage, detection of particles can obtain the result of first time Preliminary detection through the Change of light energy size after this passage, along optical path direction, first slit is amplified, then the direction that position is perpendicular is therebetween at storing second slit, coordinating image amplifying device to survey again, the second slit Change of light energy situation below can improve detection of particulates detects lower limit, improve the degree of accuracy of detection of particulates.
