A screw nail hole is arranged near the opening of the upper side of a sample groove which is fixedly connected with an opening cover plate of the sample groove in a sealed mode, and a washer is arranged between the screw nail hole and the opening cover plate of the sample groove. The inner wall of a sample groove cover is sheathed with a screw thread. One end of the screw thread is screwed on the sample groove, and the other end and a drive rod whose one end is provided with a screw thread are in screw connection together. The other end of the drive rod is connected with a rotation motor through a drive device. The utility model can make the large granules evenly dispersed, and has obvious effect to the research of the distribution and the size of the liquid drop. The measuring precision is enhanced, and the utility model is simple and practical.
Description
The utility model belongs to measurement mechanism, particularly measures the particle size analyzer of particle and drop size.
Existing measurement to particle and drop size comprises sampling and measuring methods such as on-line measurement method such as electric-resistivity method, light scattering method, supercritical ultrasonics technology, the method for taking pictures and photograph counting method.But, thereby influenced the precision of measurement result because there is problem more or less in the device that these methods adopted.Can upset the type of flow in the stirrer or bring impurity into as electric-resistivity method and supercritical ultrasonics technology, bring error to experiment; And take pictures method and light scattering method can't be studied in the measured object certain any distribution of particles.Though the photograph counting method is directly perceived, workload is very big, and man's activity big (the subjective decision of the scope of taking a sample during measurement).If the measurement drop, drop can not continue to guarantee spherical, the diameter of surveying bigger than normal; And since drop can single berth on the test sample platform, the drop on upper strata can cover the drop of lower floor, brings error.Measurement to drop at present also has the Coulter particle size analyzer, and its measuring method is simple and direct, and cardinal principle is to make measured object pass through an adjustable slit, utilizes electric quantity change to measure.Though this method has solved the scattering problem of drop, because measured object will pass through slit, drop and particle might be bonded on the path, cause experimental error, and clean very difficult.Dispersion medium when measuring simultaneously adopts water or oil, cleans also very trouble when changing medium.And the Malvern particle size analyzer is to put into stirrer in sample cell, makes the stirrer rotation with magnetic stirrer below, and measured object is disperseed in sample cell, measure then, it has adopted sample cell to measure, and has therefore reduced the difficulty of cleaning, and can not bring pollution to instrument.But this particle size analyzer adopts stirrer that measured object is disperseed, and therefore can not make it even dispersion to bigger particle, then can make it to break for drop, can not get distributing accurately.
The purpose of this utility model is to overcome the existing defective of measuring particle and drop device, provides a kind of and not only cleans measurement mechanism easily but also can improve the measurement particle of measuring accuracy and the particle size analyzer of drop size.
The purpose of this utility model is to realize like this.It is sample to be put into sample cell and make the sample cell rotation, controls certain rotating speed, makes measured object be positioned at the path of laser substantially, and can accurately obtain the distribution of measured object granularity this moment.The lid on sample cell top is to prevent that test solution from spilling sample when rotated, and groove lid inwall adds screw thread, can connect drive link like this, and drive link links to each other with screw with belt pulley, drives belt pulley with the belt on the motor, makes the sample cell rotation by drive link.
Particle size analyzer of the present utility model comprises sample cell and the sample cell lid of containing sample, the other screw hole that is provided with of top opening part that it is characterized in that sample cell, its fixed seal connection sample groove opening cover plate, between has a packing ring, and cover plate can be by screw retention on sample cell; Be with screw thread at a sample cell lid inwall, the one end is the same with conventional instrument to be screwed on the sample cell, and the other end is screwed on the screwed drive link of an end, and the other end of drive link connects rotation motor by gearing.
Packing ring of the present utility model can be materials such as rubber, plastics, metal and makes, drive link is to connect motor by driving-belt again after a belt pulley is fixed at this place with being connected of gearing, or directly on drive link, have for the groove of transmission with belt is installed, connect motor by driving-belt, or on drive link, have shaggy tooth, by the motor that is connected with a joggle between the gear.
The utility model can make bulky grain evenly disperse, and the slight disturbance of fluid can not cause breaking of drop yet under the slow-speed of revolution, can record the size and the distribution of particle rapidly and accurately, thereby has improved the precision of experiment; Solved the measurement difficulty of drop simultaneously, special aspect the measurement of drop, by the distribution situation of drop in the sampling and measuring study sample groove, distribution and the size of studying drop more there is significant effect, improved measuring accuracy, and simple and direct practicality.
Below in conjunction with accompanying drawing the technical solution of the utility model is further described.
