Description

Filter equipment convenient to screening function

Technical Field

The utility model relates to the technical field of filtering devices, in particular to a filtering device with a screening function.

Background

The process of breaking up material into different fractions by one or more layers of screening surface is called screening. The sieving machine is vibration sieving mechanical equipment which utilizes the relative motion of the granular materials and the sieving surface to enable partial particles to penetrate through sieve holes and divide the materials such as sand, gravel, broken stone and the like into different grades according to the particle size. The screening process of the screening machine is generally continuous, and after screening raw materials are applied to a screening machine (called a screen for short), the materials smaller than the size of the screen holes penetrate through the screen holes, so that the materials are called undersize products; the material larger than the mesh size is continuously discharged from the screen surface and is called the on-screen product.

In the age of technology development, the screening of materials is very important in production, the vibrating screen filter device is generated, and the basic principle of the standard inspection screen is that the rotating motion of a motor is converted into horizontal, vertical and inclined three-dimensional motions through eccentric weights arranged at the upper end and the lower end of a motor shaft, and the motions are transmitted to a screen surface. The material is forced to roll, rotate and jump on the screen mesh, and can be used in combination with standard screen grids for inspection, measurement and the like of particle size structures, liquid solid content, sundry quantity of granular and powdery materials. The device is widely applied to inspection, screening, grading, granularity analysis, impurity content analysis and the like of materials such as solid, powder slurry and the like in scientific research units, laboratories, inspection rooms, production control and the like in the industries such as food, medicine, chemical industry, abrasive, pigment, mine, metallurgy, geology, ceramics and the like.
