Mesh belt type screen exchanger

Abstract

The invention relates to the technical field of screen changers, in particular to a screen belt type screen changer which is characterized in that an upper cover plate is fixed to the upper end of an inner layer, the arc outer walls of the upper end and the lower end of an upper driving rotating rod are provided with side strips matched with limiting inserting grooves in an inserted mode, and the positions, corresponding to diameter expanding holes, of the outer wall of the driving rotating rod are telescopically provided with four sets of outer arc plates distributed in a circumferential array mode; four groups of outer arc plates are arranged in the middle of the filter screen belt, inner arc plates are connected to the inner sides of the four groups of outer arc plates, conical rods pulled by pull ropes are vertically inserted into the four groups of inner arc plates which are distributed in a circumferential array mode, and the outer arc plates extend to the position between a pair of limiting inserting grooves which are distributed up and down. And meanwhile, the purpose of controlling telescopic adjustment of an outer arc plate is achieved by arranging a conical rod to ascend and descend, so that the outer arc plate is fixedly clamped in an inner cavity of a stand column, staggered clamping is formed, the purpose of protecting a rotating rod is achieved under the impact of raw materials, and the filter screen belt smoothly moves in the transverse direction.

Description

technical field [0001] The invention relates to the technical field of screen changers, in particular to a mesh belt type screen changer. Background technique [0002] The screen changer is mainly used to replace the filter screen in the filter assembly, and it is convenient to achieve rapid replacement by setting the screen changer. [0003] The existing screen changer is usually facing the filtering raw material, and in order to improve the filtering efficiency, it is usually necessary to accelerate the raw material, so that the raw material impacts on the filtering screen, so as to achieve the purpose of enhancing the fluidity and improving the filtering efficiency. [0004] However, in the actual process of filtering and changing the screen, for the raw materials with high pressure, it is very easy to cause the filter belt to be pulled, which will cause the deformation of the filter screen and affect the filtration quality. The net is difficult to achieve lateral tracti...

[0004] However, in the actual process of filtering and changing the screen, for raw materials with high pressure, it is very easy to cause the pull of the filter belt, which in turn causes the deformation of the filter screen and affects the filtration quality. It is difficult for the net to achieve lateral traction and cannot complete the filtration
