Variable sieve pore and reciprocating pressure vibration combined pulp screening equipment

Abstract

The invention provides variable sieve pore and reciprocating pressure vibration combined pulp screening equipment. The screening equipment mainly comprises a qualified pulp generating device, a powerdriving device, a reciprocating pressure vibration device composed of upper and lower sieve plates and springs, a sieve pore diameter changing device composed of middle sieve plates and arc plates, apulp separated storage device, a guiding flow device and a turbulence crushing device. The screening equipment is characterized in that the diameters of sieve pores are automatically changed, and qualified pulp is screened out through pressure and vibration combination. According to the screening equipment, the qualified pulp is generated by the qualified pulp generating device, the driving forcefor reciprocating motion is provided through the power driving device, reciprocating pressure and vibration screening of the pulp are achieved through the reciprocating pressure vibration device, thediameter change of the sieve pores and auxiliary pressure screening are achieved through the sieve pore diameter changing device, the separated storage of the pulp and fine materials is achieved through the pulp separated storage device, motion guiding and flow guiding of coarse materials and the fine materials are achieved through the guiding flow device, and impact turbulence and shear breakingof the coarse materials are achieved through the turbulence crushing device.
