example

[0045] Process flow chart of the present invention is as Figure 7 Shown:

[0046] 1. The algal water enters the steady flow box from the water inlet pipe for preliminary steady flow, and at the same time, the motor is turned on to control the rotation of the filter drum.

[0047] 2. The motor of the power part drives the filter roller to rotate, so that the algae water overflowing from the steady flow tank is centrifugally filtered. The filtered clean water is drained into the water collection tank by the drainage plate, and part of the clean water is directly discharged from the drain hole. The other part of clean water is passed into the booster pump through the return pipe to increase the pressure, and then passed into the spray pipe through the high-pressure hose, and finally sprayed out by the high-pressure nozzle made under the spray wheel rod. The high-pressure nozzle is facing the filter Above the screen drum, and can realize the dynamic telescopic spraying of the sc...

Abstract

The invention provides a centrifugal filtration apparatus for algal water and with self-cleaning function. The centrifugal filtration apparatus comprises a water inlet pump, a filter box, a water outlet pipe and an algae outlet pipe. An algal water separating device is arranged between the water inlet water pump and the filter box, and comprises a base, a base support, a power part, an algal waterfiltering unit and a cyclically flushing unit, wherein the base support is provided with the power part; and the algal water filtering part is installed on the upper part of the base, connects with the filter box via a pipeline and rotates under the driving of the power part so as to realize centrifugal filtration of algal water in the centrifugal filtration apparatus. The centrifugal filtrationapparatus may be a rotatable mechanism of a cylindrical shape, a cone shape, a fusiform shape or the like; the cyclically flushing device capable of cyclic flushing of the algal water filtering deviceis erected on the upper part of the algal water filtering device; the centrifugal filtration apparatus can realize centrifugal separation of the algal water and self-cleaning, and a cleaning system can cyclically use separated clear water; and the centrifugal filtration apparatus greatly saves water resources and power resources, is convenient to operate and low in cost, and is especially applicable to large-scale algal water filtering in medium-sized and large lakes and reservoirs.

Description

technical field [0001] The invention belongs to the field of mechanical devices, and relates to a filter mechanical device, in particular to a self-cleaning algal water centrifugal filter device. Background technique [0002] Currently limited by the demand for drinking water in water sources, the algae removal technology that is widely used in large and medium-sized lakes and reservoirs is mainly to remove algae mechanically. The algae harvesting boat is a more commonly used tool for algae collection. It uses a submersible pump to suck algae-rich water into the hull to dehydrate and collect algae mud. In addition, shore-based fixed cyanobacteria harvesting methods are also more common, that is, algae water separation stations are established on the shore of lake reservoir areas where cyanobacteria blooms are easy to gather, and the collected algae-rich water is concentrated and dehydrated using vibrating inclined screens and decanter centrifuges. . Among the above-mention...
