Compound pure water filtering machine

Abstract

The invention discloses a compound pure water filtering machine which comprises a barrel, an inner filter screen, an outer filter screen and a T-shaped feeding pipe, wherein the barrel is supported by bottom studs; the inner filter screen and the outer filter screen are arranged in the barrel in turn from inner to outer and are coaxial with the barrel; a discharging hole is formed in the end part of a vertical pipe of the T-shaped feeding pipe; a flow adjusting mechanism is mounted on a feeding hole of the T-shaped feeding pipe; a disc distributing head is arranged at the discharging hole of the T-shaped feeding pipe; a plurality of injection pipes forming same angles with the radius of the inner filter screen are uniformly distributed on the disc distributing head; a rotating mechanism, which is integrally connected with the inner filter screen, takes the impacting resultant force of water flow jetted by the injection pipes to the inner filter screen as power and rotates around the axis of the vertical pipe of the T-shaped feeding pipe, is mounted on the T-shaped feeding pipe. The compound pure water filtering machine can be used for effectively filtering fibers from pure water, recycling and reducing discharged solids and increasing the yield of raw materials. Filtered water acquired according to a physical method can be applied to common low-pressure spraying and the purpose of saving clean water can be achieved.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a compound white water filter. Background technique [0002] In the paper industry, the water removed during web forming in the wet end of the paper machine, as well as the water removed further by vacuum boxes and presses, are collectively referred to as "white water". White water contains fibers, fillers and soluble paper-making chemicals. Separating these substances can be recycled, and the filtered water can be used for spraying operations on process points that do not require high water quality. It can be seen that white water treatment can greatly improve the yield of raw materials. efficiency, cost savings, and reduced pollution. [0003] At present, the main methods of papermaking wastewater treatment at home and abroad are coagulation method and biochemical method. The equipment for treating papermaking wastewater by coagulation is mainly inclined plate sedimentation tan...

AI Technical Summary

Problems solved by technology

This method requires a lot of investment and energy consumption, and the treatment cost is high. The treated sediment can only be discharged as waste, wasting recyclable fibers; and its biochemical treatment of white water requires a large area and high power consumption.
