Particle crusher for laboratory

Abstract

The invention discloses a particle crusher for a laboratory, and relates to the technical field of crushing devices. The particle crusher for the laboratory comprises a box body, wherein a cyclone generator is fixedly connected to one surface of the box body; an outer rod is rotationally connected to one surface of the box body through a bearing; an inner rod is rotationally connected to the innerwall of the outer rod through a bearing; one end of each of the inner rod and the outer rod extends into the box body; one end of an outlet of the cyclone generator rotationally communicates with theinner rod; and air outlet ports are formed in the peripheral surfaces of the inner rod and the outer rod separately. According to the particle crusher for the laboratory, through designs for the cyclone generator, the air outlet ports, a crushing cutting edge, a movable cutting edge and a pre-crushing chamber, during crushing of the crushing device, on one hand, the pre-crushed small particles can be raised in a manner of charging cyclone, and then the contact frequency of materials and the crushing device is increased, and the crushing effect is improved; and on the other hand, the materialsleft on the crushing cutting edge and the movable cutting edge can be eliminated in real time in a manner of ventilation, so that the device has a self-cleaning function.

Description

Technical field [0001] The invention belongs to the technical field of crushing devices, and particularly relates to a particle crusher used in a laboratory. Background technique [0002] The chemical laboratory is an important place to provide chemical experiment conditions and scientific exploration; there are a large number of instruments in it: iron stand, asbestos net, alcohol lamp, beaker, test tube, gas cylinder, rubber stopper, reagent bottle, mortar, etc. Experimental tools; usually equipped with a chemical cabinet, which contains commonly used chemicals, such as: copper sulfate pentahydrate, sodium hydroxide solution, limestone, hydrochloric acid, etc. [0003] There are also some mechanical instruments in chemical laboratories. These instruments are mainly used for pretreatment of experimental raw materials. Grinding and crushing equipment is essential. Some chemical experiments need to dissolve solids, which requires Firstly, crush and grind large-particle solid raw ma...
