Automatic filter residue concentrating filter

Abstract

The invention discloses an automatic filter residue concentrating filter, which is simple in structure, has few moving and wearing parts, is high in efficiency and is energy-saving, can significantly reduce the backwashing times, has greatly lowered backwashing water consumption, and can highly concentrate filter residues. The automatic filter residue concentrating filter consists of an electromagnetic vibrator, a vibrating tube, a barrel body, a filter screen barrel, a residue discharging control valve, electromagnetic valves, water inlet pipes and a water outlet pipe, wherein the filter screen barrel is arranged inside the barrel body; the vibrating tube, the electromagnetic vibrator and the water inlet pipes are arranged on the filter screen barrel; residue discharging pipes and the residue discharging control valve are arranged at the lower end of the filter screen barrel; the water outlet pipe is arranged at the lower end of the barrel body. When the automatic filter residue concentrating filter works, under the actions of vibration of the electromagnetic vibrator and pressure of a water pump, the filter residues in feed liquid entering the filter screen barrel quickly precipitate to the lower end of the filter screen barrel, and are discharged out of the automatic filter residue concentrating filter from the residue discharging pipes by passing through the residue discharging control valve; filtered water flows out from a filter screen, and flows out of the automatic filter residue concentrating filter through the water outlet pipe at the lower end of the barrel body; when the inner wall of the filter screen barrel is blocked, backwashing water enters the barrel body, and enters the filter screen from the filter screen barrel to backwash the filter residues on the filter screen, and sewage is discharged out of the automatic filter residue concentrating filter from a drain pipe by passing through the outer residue discharging pipe.

Description

technical field [0001] The invention relates to sewage treatment equipment, which belongs to the technical field of water treatment. Background technique [0002] At present, when the sewage treatment filters on the market are in operation, the filter residue gradually forms high-concentration sewage in the filter screen, but the filter screen holes are quickly blocked. After the filter screen is blocked, it is generally necessary to use a considerable amount of clean water each time. In this way, the clogged filter mesh holes can be flushed and continued to be used. This operation has the disadvantages that the filter mesh holes are blocked by the filter residue quickly, the number of backwashing times is large, the amount of clean water is large, and the energy consumption is high. Contents of the invention [0003] The content of the invention is: to solve the shortcomings of the current sewage filters on the market that the filter mesh is blocked by the filter residue ...
