Automatic efficient filtration residue concentration filter

Abstract

An automatic high-efficiency filter residue concentration filter capable of continuous filtration, large flow rate, less water consumption for backwashing, and highly concentrated filter residue. It consists of a cylinder, a two-way filter cylinder, a recoiler, an electromagnetic vibrator, a hydraulic cylinder, a solenoid valve, a water inlet pipe, a water outlet pipe and a high-pressure water pipe. There is a two-way filter cylinder inside the cylinder, and a recoil device is installed inside the two-way filter cylinder. The upper end of the recoil device is equipped with a hydraulic cylinder and a movable plate drive device. Vibrator, slag discharge pipe and solenoid valve. During operation, the sewage enters the cylinder from the water inlet pipe, and flows inward from both sides of the two-way filter cylinder for filtration, and the filtered water flows out of the machine through the outlet pipe above it, and the filter residue quickly settles down under its own gravity and the vibration of the electromagnetic vibrator Concentrated in the slag collecting hopper, when the filter screen is blocked by filter residue, the high-pressure water sprayed from the water nozzle by the backwasher will fully backwash the filter screen, and the filter residue in the slag collecting hopper will be discharged out of the machine through the filter residue 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, and the filter screen needs to be backwashed with a considerable amount of clean water every time after the filter screen is blocked. , so that the clogged filter holes can be flushed out and continued to be used. The filter residue is automatically deposited to the lower part of the filter, and the speed is slow. In this way, the filter hole is blocked by the filter residue during operation. The disadvantages of large quantity and high energy consumption. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the current sewage filters on the market that th...

Problems solved by technology

[0003] The purpose of the present invention is to solve the shortcomings of the current sewage filters on the market that the filter mesh holes are blocked by the filter residue quickly, the amount of clean water for backwashing is large, and the energy consumption is large. The invention has high efficiency, continuous filtration, and large water output. Increased by more than three times, the number of backwashing and water consumption are less, and the filter residue can be highly concentrated, especially suitable for various filter presses as an automatic high-efficiency filter residue concentration filter used as the pre-filter slurry concentration equipment
