Automatic wet type screening machine

Abstract

The invention discloses an automatic wet type screening machine, and relates to the technical field of ore fine sieving. The automatic wet type screening machine comprises a screening machine body anda transmission part. The transmission part comprises a motor. The output end of the motor is in transmission connection with an eccentric shaft through a belt wheel. The surface of the eccentric shaft is sleeved with a bearing. According to the automatic wet type screening machine, through the structure design that the motor drives an eccentric shaft rocker, a sieve has a basic vibration function, through the structure construction of a screen underflow ore receiving groove, basic conditions of proceeding of wet type screening in water are met, the usage functions of the screening machine areenriched through frequency modulation and timing design, and different screening requirements are met. Since application of an automatic screening machine sample machine, the screening effect is good, no difference basically exists between automatic screening and manual screening, under the situation that screen underflow does not need to be recycled, two same-grain-size ore samples can be simultaneously screened every time, the laboratory sample screening efficiency is effectively improved, the work intensity of experiment personnel is reduced, and good practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of ore fine screening, in particular to an automatic wet screening machine. Background technique [0002] In the production site of metal mines or in scientific research institutes such as mine design institutes, in order to explore the natural particle size composition of minerals or the effect achieved after crushing and grinding, fine sieves are often used for experimental inspection. When it is finer, wet sieving is often used. [0003] In the current laboratory wet sieving analysis, the method used is manual sieving. The limitations of this method are: the sieving speed is slow, and the manual efficiency is low, especially the finer the sieve and the narrower the mineral particle size. The longer the sieving time. The screening time of each ore sample refers to the time taken from the beginning of screening to the end of screening (continue to screen for 1 minute, the amount of ore under the screen is...
