Centrifugal filtration apparatus for algal water and with self-cleaning function

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...

Problems solved by technology

Among the above-mentioned mechanical algae harvesting technologies, although the algae removal effect is better, the cost needs to be several million to tens of millions, and the processing cost is high, so it is not suitable for large-scale promotion and use.
