Description
Technical field
The invention belongs to powder processing machinery field, and in particular to one kind is wet sieving to use vibratory sieve.
Background technology
With continuing to develop for powder industry and increasing for application field, the interior requirement to powder of industry is also more and more tighter
Lattice, and size distribution is also stood in the breach as the exemplary parameter of particle, is that this should be sieved to powder.At present in industry
It is interior to be divided into dry and wet to the method for sieving that powder is commonly used, and dry screening is narrower using scope, and yield is less；Wet method
Screening goes for industry-by-industry, and production yields is big, it is easy to industrial applications, wherein representative is vibratory sieve.
The vibratory sieve used in current industry can be divided into spin vibration sieve, ultrasonic activation sieve and slap sieve etc. according to function, but
Above-mentioned each function vibratory sieve all has a problem that, i.e. the easy plug-hole of screen cloth, and sieve mesh number is more big more easily causes screen cloth plug-hole,
Influence production efficiency and increase the workload of operator.In general particle size 10um or so powder, with vibration riddler
Operator is accomplished by as 15-10min to be rinsed screen cloth, and the solid-to-liquid ratio of particle and decentralized medium can not be too high, typically
Control within 15%, and solid-to-liquid ratio more than 15% after the flushing frequency of operator will increase, increase labor intensity.From enterprise
From the point of view of angle, low production efficiency and cost of labor increase, all can be that enterprise is on a sticky wicket in market competition.
The content of the invention
Easily block the phenomenon of mesh in use it is an object of the present invention to solve vibratory sieve, improve filtering
The solid-liquid ratio of powder, and powder is improved into production efficiency.
The present invention is directed to the defect of existing vibratory sieve, and the invention provides a kind of wet sieving vibratory sieve.
