Automatic backwashing viscose filter

Abstract

The invention discloses an automatic backwashing viscose filter, belonging to filtering machinery. A rack is provided with a cylindrical filter drum body; two ends of the filter drum body are respectively provided with a front drum body end cover and a rear drum body end cover which are respectively and fixedly provided with an ejecting rod component; the filter drum body is provided with a viscose outlet near the rear drum body end cover; a waste viscose outlet and a viscose inlet are arranged at the rear drum body end cover; a mesh cage is arranged inside the filter drum body; the two ends of the mesh cage are connected with the front drum body end cover and the rear drum body end cover; a protective mesh is fixed on the surface of the mesh cage by a clamping plate and a hoop; a filtering mesh is wrapped and clamped between a lining mesh and the protective mesh; the lining mesh is wrapped and clamped between the mesh cage and the filtering mesh; two ends of a center pipe are respectively inserted in hole slots in the central parts of the front drum body end cover and the rear drum body end cover; a backwashing piston is located inside the mesh cage and sleeved on the center pipe; a safety coupler is connected with a speed reducer; and the speed reducer is connected with a motor. For the filter, an automatic filtering system is designed according to an osmosis filtration principle, and a PLC (Programmable Logic Controller) technology is adopted, so that the automatic backwashing viscose filter can achieve automatic control, continuous work, automatic backwashing and automatic residue discharge.

Description

technical field [0001] The invention relates to the technical field of filtering machinery, in particular to an automatic backwashing viscose filter. Background technique [0002] Since the reform and opening up, the national economy has grown rapidly, and "scientific and technological innovation, independent innovation" has become the mainstream of domestic industrial development. my country's industry is gradually developing in the direction of intensive, energy saving, emission reduction and low carbon. In recent years, with the improvement of my country's textile market, a new batch of viscose fiber projects have been launched all over the country, and the scale is huge, which fully reflects the trend of large-scale and large-scale equipment. In the production of viscose fiber, the filtration of the raw solution is indispensable. The inorganic and organic particles in the viscose must be effectively filtered out in order to reduce the wool and improve the uniformity and...

Problems solved by technology

However, because the domestic KKF filter is not as good as the imported equipment in processing quality and processing accuracy, it has caused a lot of waste and difficulties in production balance during use.

The existing problems are highlighted as follows: 1. The sealing performance of the piston ring is poor, and the amount of waste rubber is large; 2. The backwashing effect is poor, the backwashing is frequent, and the amount of glue is low; 3. The pressure of P2 is unstable, which affects the backwashing effect; 4. , After the filter has been used for a period of time, the amount of glue passing has dropped significantly, etc.

The technicians of scientific research units and enterprises are constantly exploring and researching, hoping to develop a viscose filter with superior performance to replace imported ones. Although some progress has been made, there are still technical problems that have not been overcome in practical application.
