Abstract
The utility model relates to an automatic measurer for the interfacial tension of a rotary axle, which is characterized in that the utility model uses a motor (1) to drive a wheel shaft (3) and a sample tube (4) to rotate with high speed via a belt wheel group (2); the dimension of a sample (6) in the sample tube which rotates with high speed is changed; under the irradiation of a light source (5), the image of the sample is projected in the optical lens of a video camera (8), and then is introduced into a computer (9) via the connecting board of a computer interface to be processed, to form the image and to reckon upon the interfacial tension.
Description
The utility model relates to a kind of interfacial tension analyzer that revolves automatically, is the instrument that adopts computing machine and measurement mechanism that interfacial tension between static liquid is measured automatically.
No matter present interfacial tension analyzer is to adopt to revolve that to drip or revolve a mode (U.S. Patent number 4644782) all be to adopt microscope, observes with human eye.By the scaleplate in the microscope, to read the size of sample and calculate, this method wastes time and energy, because the human eye parallax, accuracy is not high.
The purpose of this utility model is that an a kind of improved interfacial tension analyzer device that revolves automatically will be provided, and it can be measured effectively automatically.
The purpose of this utility model is achieved in that
Use WV-CL320 type video camera that the sample in the interfacial tensimeter is carried out the imaging shooting, then, the picture of gamma camera is directly imported the AST286 computing machine handle, calculate interfacial tension.
Specifically be exactly to drive wheel shaft and sample hose high-speed rotation by the belt wheel group with the 12V direct current high-speed electric expreess locomotive that Shanghai micromotor factory produces, sample is under high speed rotating, sample size changes, under the irradiation of light source, sample image is projected in the camera lens of WV-CL320 type video camera, import the AST286 computing machine by the computer interface fishplate bar then and handle, imaging, calculate interfacial tension, interface board is the color card of commercially available DA501 plus linear array card and VC32plus.It is characterized in that sample hose (4) is positioned at light source (5) and video camera (8) camera lens middle.
The utility model is because of only changing the observation of microscope human eye into video camera imaging on the basis of existing interfacial tension analyzer and being handled by computing machine, so can improve the accuracy of measurement, time saving and energy saving, efficient significantly improves, and has realized robotization control.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 revolves an interfacial tension analyzer automatically according to what the utility model proposes.
Fig. 2 is the circuit theory diagrams of lamp source and motor;
Describe details and working condition in detail below in conjunction with Fig. 1 and 2 according to the concrete device that the utility model proposes.
This device is to drive wheel shaft (3) and sample hose (4) high-speed rotation by 9000 rev/mins of high speed direct current generators of per minute (1) by belt wheel group (2), sample (6) changes in sample hose (4) inside dimension of high speed rotating, press Fig. 2 principle under the irradiation of light source (5) (6 volts of 9 watts of lamps that Nanjing Special Bulbs Factory is produced), sample image is projected in WV-CL320 in the optical lens of video camera (8), importing AST286 computing machine (9) by the computer interface fishplate bar then handles, imaging, calculate interfacial tension, interface board is the color card of commercially available DA501 plus linear array card and VC32plus.How computing this be apparent for a person skilled in the art.
A kind of interfacial tension analyzer that revolves automatically, it is characterized in that this device is to drive wheel shaft (3) and sample hose (4) high-speed rotation by motor (1) by belt wheel group (2), is characterized in that sample hose (4) is positioned between the camera lens of light source (5) and video camera (8).
Claims (1)
1, a kind of interfacial tension analyzer that revolves automatically, this device is to drive wheel shaft (3) and sample hose (4) high-speed rotation by motor (1) by belt wheel group (2), sample (6) changes in sample hose (4) inside dimension of high speed rotating, under the irradiation of light source (5), sample image is projected in the optical lens of video camera (8), import computing machine (9) by the computer interface fishplate bar then, handle, imaging, calculate interfacial tension, it is characterized in that sample hose (4) is positioned at the camera lens middle of light source (5) and video camera (8).
