Problems solved by technology

[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

Embodiment 1

[0031] A mesh belt type screen changer, the screen changer includes an inner layer 1, a mesh belt 4, a column 5 and an upper cover 12

[0032] The two sides of the inner layer 1 are provided with a net trough 10, the outer side of the inner layer 1 is symmetrically provided with a pair of rotating winding rollers 2 and unwinding rollers 3, the middle of the inner layer 1 is vertically rotated and installed with a column 5, and the net trough 10 A pair of rotatably installed guide rollers 7 are arranged on both sides of the upright column 5, and a filter inner cavity 6 is arranged in the middle of the inner layer 1. The two sides of the filter inner cavity 6 are connected to the mesh slot 10, and the upright column 5 is installed in the filter inner cavity 6. In the middle, the inner layer 1 is provided with temperature control grooves 11 located on both sides of the mesh groove 10 .

[0033] A column 5 and a guide roller 7 are arranged in the middle of the mesh belt 4 to form ...

Embodiment 2

[0039] On the basis of Example 1, in order to improve the tightness of the lower end of the upright column 5 and prevent leakage of raw materials from unfiltered, affecting the quality of filtration, the present application also has a discharge port 9 and a feeding port on the front and rear sides of the filter cavity 6. Port 8, the lower end of the filter cavity 6 is provided with a base 15, the base 15 is sealed and installed on the inner wall of the lower end of the inner layer 1 through a fixed column 16, the lower end of the column 5 is rotated and installed on the base 15, and the column 5 is located close to the feed port 8 The upper end of the base 15 is vertically provided with a lower pin 18, a circular sealing ring 17 is pressed between the lower end of the base 15 and the inner wall of the lower end of the filter cavity 6, and the upper end surface of the base 15 is provided with The annular sealing drum 19 located on the outside of the lower pin 18, the lower end o...

Embodiment 3

[0042] On the basis of Example 2, in order to prevent the raw material from falling and cooling and causing bonding with the lower end of the mesh belt 4, making it difficult for the mesh belt 4 to drive laterally, the present application also has a setting on the side of the upper end of the base 15 close to the feed port 8 There are three groups of heated bottom rollers 24, the heated bottom rollers 24 are located on the outside of the column 5, and there is a gap between the heated bottom roller 24 and the arc outer wall of the column 5, the mesh belt 4 slides through the gap, and the upper end of the driving rod 20 is set There is a baffle 14 , the outer diameter of the baffle 14 is larger than the outer diameter of the column 5 , and the baffle 14 is pressed against the upper end surface of the column 5 .

[0043] The position of the mesh belt 4 is limited by setting the baffle 14 and the heated bottom roller 24 , and the heated bottom roller 24 is used to heat the raw mat...

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...
