Abstract
The utility model discloses an optical scanning mechanism of light transmitting sedimentation type particle-size analyzer. Light transmission portion and light receiving portion on same light path are respectively installed on synchronizing lifting platforms at both sides of sample cell; straight light is adopted to perform reciprocating photoscanning test of sample in the sample cell; and collimating lens and slit as well as optical receiver are employed to replace conventional complex light path and photoelectric conversion structure to simplify overall structure, facilitate assembly and adjustment, and lower cost.
Description
Technical field
The utility model relates to the architecture advances technology of the saturating decanter type particle-size analyzer of light.
Background technology
The saturating decanter type particle-size analyzer of light is widely used in the field tests such as metal, nonmetal, metal oxide, catalyzer, fluorescent powder, stupalith, fire resistive material, various slurry, suspending liquid.In light fixed point scanning particle-size analyzer, the structural group of its photoscanning part of detecting becomes: include the cam-type light scanning mechanism, the lens specimen groove, the integrating sphere photoelectric commutator, its cam-type light scanning mechanism is used for rotatablely moving of square cam is converted into by the up and down reciprocatingly operation of cantilever drive concave mirror at certain angle range internal reflection light, realize the shuttle-scanning of light at the lens specimen groove, the convex lens that are provided with through lens specimen groove side make the parallel sample that evenly sees through of light, the convex lens focus of passing through opposite side is gathered value of electrical signals by photoelectric commutator on integrating sphere again, carry out data processing by central control unit and realize Measurement and analysis.As from the foregoing, this test structure is very complicated, it is all comparatively difficult on the particularly processing of square cam, installation and light path are adjusted, its loaded down with trivial details light channel structure causes that its optical device difficulty of processing is big, fitting operation requires height, also can therefore strengthen measuring error, but also have whole instrument manufacturing cost high-technology problem.
The utility model content
Goal of the invention of the present utility model is to provide the saturating decanter type particle-size analyzer of the simple light of a kind of light channel structure light scanning mechanism.The saturating decanter type particle-size analyzer of light of the present utility model light scanning mechanism technical scheme, its major technique content is: the saturating decanter type particle-size analyzer of a kind of light light scanning mechanism, the same linear light path setting in two opposite sides that light source transmission part in this mechanism and light receiving part are positioned at sample cell, light source transmission part and light receiving part are fixedly installed on the hoistable platform that is parallel to the sample cell linear running, and its light source transmission partly is to be made of the collimation lens and the slit that are provided with in light source and the hoistable platform bracing frame lens barrel.
The saturating decanter type particle-size analyzer of the disclosed light of the utility model light scanning mechanism technical scheme, its light source transmission part and light receiving part are arranged on the hoistable platform that moves up and down along with straight line jointly, by its linear light path the sample of sample cell is implemented reciprocal photoscanning test, the mechanical realization that has replaced original square of cam and cantilever, collimate light path and the opto-electronic conversion structure that lens and slit and light receiving element have substituted original complexity by one, thereby greatly simplified the light scanning mechanism composition, to its parts processing, installation and debugging etc. are all very easy, and be easy to implement more convenient and accurately control neatly, therefore improved measuring accuracy greatly the operation of light scanning mechanism, enlarged test specification.Because present technique is simple in structure, composed component is few, be easy to assembling and debugging, its cost also obviously decreases.
Description of drawings
Accompanying drawing is the general assembly structural representation of the saturating decanter type particle-size analyzer of the utility model light light scanning mechanism.
Embodiment
As shown in the figure, the saturating decanter type particle-size analyzer of light of the present utility model light scanning mechanism, the same linear light path setting in two opposite sides that light source transmission part in this mechanism and light receiving part 12 are positioned at sample cell 11, two parts all are fixedly set on the same hoistable platform 13, this hoistable platform 13 drives the linear running that work parallels with sample cell by stepper motor 2, in the present embodiment, these hoistable platform 13 spirals are arranged on the motor screw output shaft 3, for realizing the straight-line guidance operation, be integrally formed with the slide block 8 that leads by linear running slideway 9 with hoistable platform 13.Being arranged at sample cell 11 1 sides is light source transmission part, is made of the collimation lens 6 and the slit 10 that are provided with in light source 5 and the hoistable platform bracing frame lens barrel 7; The opposite side that is positioned at sample cell 11 on the hoistable platform 13 is a light receiving part 12, and in the present embodiment, what this light receiving part 12 adopted is photoelectric cell.Its photoscanning work is by the central control unit of instrument stepper motor driving circuit to be exported control signal corresponding, and the accurately operation of control step motor drives the photoscanning part sample in the sample cell is carried out strict photoscanning.
