Description

Liftable intelligent rotary algae filtering and collecting equipment

Technical Field

The utility model belongs to water ecological protection and water treatment field, concretely relates to liftable intelligent rotation algae filtration collecting device.

Background

The problem of abnormal proliferation of algae in lakes, reservoirs, rivers and water delivery channels in China is frequent, and the in-situ filtration and the removal of the algae from the algae-containing water body are important means for ensuring the safety of drinking water and the health of a water ecosystem. The grid sewage removing machine is a device for fishing out the sewage in the water body through grid filtration, is widely applied to occasions such as urban domestic sewage treatment and industrial wastewater treatment, and is mainly used for removing larger solid matters in the sewage. The conventional grate cleaner is of a rotary type, and under the driving of a driving device, rake teeth arranged on a rotary chain at certain intervals continuously rotate, so that dirt intercepted by a grate is fished out; the step-type grid cleaner with the rotary screen plate is also manufactured by replacing the grid with the screen plate, wherein the screen plate is made of stainless steel, the screen surface is provided with regularly arranged small holes for water passing, and the whole screen surface is processed into a step shape so as to intercept larger dirt.

The existing decontamination equipment has the following defects in the aspect of removing algae: (1) the dynamic sewage lifting device mostly adopts a fixed motor, and when the concentration of algae in water is suddenly increased and the amount of slag is suddenly increased, the filter screen is blocked, and the water level in front of the filter screen is raised; (2) for the rotary type grating dirt removing machine, the grating clearance is longer, and the dirt blocking effect of the grating is reduced for slender and fibrous solid objects; in addition, the dirt is easy to be wound on the grid bars and the toothed rakes, and the slender solid objects are difficult to be cleaned by brushes and the like, so that the dirt cleaning efficiency is reduced, and even equipment failure is caused; (3) for the step-type grid with the rotary screen plate, a plurality of holes are formed in the screen plate, the influence of the screen plate on the flow area is large, and the filtering precision of the screen plate is limited to a certain extent; (4) in the traditional maintenance of the grid sewage disposal machine, a gate needs to be arranged in front of a grid, when a fault occurs, the gate needs to be put down, and after water in a channel is emptied, a maintenance worker can maintain the channel; some problems of narrow maintenance space and limited operation of maintenance personnel exist; the maintenance time is too long, the water level of a single-equipment river channel which needs flowing water all the time is raised too much, the bearing pressure of a river channel embankment is increased, and in addition, maintenance personnel can be harmed by dangerous and toxic water or gas when the maintenance personnel operates in the channel; (5) in the conventional grid sewage disposal machine, in order to ensure that the grid chain can rotate, a sufficient safety distance needs to be reserved at the lower end of the mechanical component of the grid, and at the position, water flow directly penetrates through the machine and cannot be subjected to filtration treatment of the grid. In addition, some dirt blocked by the grating is deposited to the lower part of the grating under the action of gravity and the like, is accumulated for a long time and is accumulated to a certain height, and a rotary chain wheel and a rotary chain are wound.
