The invention provides a wet-method granule circulating device, and belongs to the field of special granule dispersion devices. The circulating device comprises a power device, a centrifugal pump assembly, an ultrasonic transducer and a solenoid valve assembly, wherein a pump body of the centrifugal pump assembly is arranged horizontally, a vane wheel is arranged on the left side of the pump body by a rotating shaft which is arranged vertically, and the rotating shaft is connected with a power output shaft of the power device positioned above the pump body; a water inlet nozzle assembly connected with the pump body is arranged between the power device and the pump body, a water pump seal assembly is arranged between the water inlet nozzle assembly and the rotating shaft, a first installing hole is formed on the pump body below the vane wheel, an ultrasonic bottom board is arranged in the first installing hole, and the ultrasonic transducer is bonded below the ultrasonic bottom board; and a water return nozzle arranged horizontally and a drainage nozzle downward vertically are formed at the right end of the pump body, the solenoid valve assembly is arranged above the pump body corresponding to the drainage nozzle, and a solenoid valve of the solenoid valve assembly is positioned above the drainage nozzle. The circulating device for the wet-method granules is applied to a laser granulometer and is connected in series with a sample barrel and a sample window to ensure that the granules are dispersed uniformly and are not interfered by air bubbles, so the circulating device can be widely suitable for wet-method dispersion of various granule groups with 0.1 to 3,000 micrometers.
Description
(1) Technical field [0001] The invention relates to a special device for dispersing particles, in particular to a wet particle circulation device which integrates circulation, drainage and ultrasound. (2) Background technology [0002] At present, the wet circulation, drainage and ultrasonic of the laser particle size analyzer are of split structure. Each device needs to be connected in series to form a circulation system, so it takes up a lot of space and requires a large amount of circulating liquid. For some valuable particles, the test waste is large. Due to the structure of the pump itself, there are liquid accumulation and air bubble interference. , affecting the test accuracy. (3) Contents of the invention [0003] The technical task of the present invention is to provide a wet particle circulation device with reasonable design, simple and compact structure and convenient use in view of the deficiencies of the prior art. [0004] The technical solution adopted by ...
