Problems solved by technology

[0003] However, due to the flat appearance of the filter screen used in the conventional technology, impurities are easy to accumulate on the filter screen, causing the filter screen to be blocked and affecting the delivery efficiency of the fluid
When the delivery efficiency of the fluid cannot meet the process requirements, it will cause process interruption or delay, which will greatly reduce production efficiency

Embodiment Construction

[0049] figure 1 What is shown is a schematic diagram of a filter screen according to an embodiment of the present invention. figure 2 shown along the figure 1 The longitudinal section view of the I-I' section line in the middle.

[0050] Please refer to figure 1 , the appearance of the filter screen 100 is conical, which can effectively increase the surface area of ​​the filter screen 100 . The filter screen 100 includes a bottom 102 and a top 104 , and the filter screen 100 converges to a point along a straight line from the bottom 102 to the top 104 , so that impurities can slide down easily, so that the filter screen can be completely blocked. Wherein, the bottom 102 is ring-shaped, although in this embodiment, a ring shape is taken as an example for illustration, but there is no special limitation on what kind of ring shape the bottom 102 is. The shape of the bottom 102 may be a polygonal ring in addition to a ring shape, and those who have ordinary knowledge in this ...

Abstract

The invention discloses a filter screen and a fluid circulation device. The filter screen has a pyramidate appearance, comprises an annular bottom and a top and is converged to a point along a straight line from the bottom to the top. When being used in the fluid circulation device, the filter screen is fixed in a pipeline connected with a pump. Because of better filter efficiency, the filter screen can prevent impurities from damaging the pump, and the cost of maintenance and replacement of the pump can be saved.

Description

technical field [0001] The present invention relates to a filter screen and a fluid circulation device, and in particular to a filter screen and a fluid circulation device which prevents the filter screen from being blocked and has high filtration efficiency. Background technique [0002] A general pump is a device used to move fluids such as liquids and gases, and it is one of the main devices in various industrial fluid circulation systems. When the fluid in the circulation system contains impurities such as by-products or other foreign matter, these impurities often cause damage to the rotor of the pump or slow speed, resulting in process interruption or delay, and serious contamination and defects in the product. In order to solve the above-mentioned problems, the way in the prior art is to set a filter screen in the pipeline to filter these impurities. [0003] However, due to the flat appearance of the filter screen used in the conventional technology, impurities are ...
