Gill type cyanobacterial harvesting ship

Abstract

The invention relates to a gill type cyanobacterial harvesting ship which includes a ship body, a cyanobacterial collection device, gill type filtering devices and a storage device, wherein the cyanobacterial collection device includes a bracket, a submersible pump assembly and an intercepting net, wherein the submersible pump assembly forms a collecting unit. The collecting unit can be adjusted up and down in the height direction of the ship body. The gill type filtering device includes a frame, a plurality of filter sieve units, an adjustment unit and a spraying unit, wherein each filter sieve unit includes a sieve frame, a screen cloth, a cyanobacterial collecting tank and liquid discharging tanks; the number of the gill type filtering devices is a plurality, the gill type filtering devices are inclined towards the middle of the ship body and draw close; the cyanobacterial collecting tank is communicated with the screen surfaces of the plurality of screen cloths and form an integraltank, the number of the liquid discharging tanks is a plurality, and the liquid discharging tanks are communicated with the back of each screen surface to drain filtrate out of the ship. According tothe gill type cyanobacterial harvesting ship, on the one hand, the harvesting interval can be controlled, and blockage is avoided; on the other hand, through a mode of discharging water through a small tank and using the integral tank to collect cyanobacterial, and harvesting workers' workload is alleviated; at the same time, reasonable layout is performed, and not only is device maintenance facilitated, but also the centre-of-gravity shift of the ship is prevented.

Description

technical field [0001] The invention relates to a water surface cleaning ship, in particular to a fish gill type cyanobacteria harvesting ship. Background technique [0002] After the emergence of cyanobacteria pollution problems in lakes in our country, various cyanobacteria collection equipment came into being. Generally, traditional algae water primary separation technologies such as belt sieve filtration, inclined plane filtration, vibrating inclined sieve filtration, flocculation air flotation separation, and electromagnetic separation are widely used. There are problems of low efficiency and high energy consumption. A single machine draws and processes tens of cubic meters of algae water per hour, and the operating power is tens of kilowatts, which is far from meeting the needs of cyanobacteria disaster control in large lakes such as Taihu Lake, Chaohu Lake, and Dianchi Lake. Tons of blue-green algae removal mainly depends on manual salvage, and there is an urgent need...

AI Technical Summary

Problems solved by technology

[0008] 1. When collecting cyanobacteria, because the collection device is positioned at the bow of the ship, the range of the collected waters is limited, and it is easy to cause blockage of the collection device, which also affects the collection efficiency and effect;

[0009] 2. During the screening process of cyanobacteria, although the angle of the screen can be adjusted according to the concentration of the collected cyanobacteria, the small groove connected to the sieve surface will easily cause the accumulation of cyanobacteria. Inconvenient to operate

[0011] 4. The gill filter is directly exposed to the outside without a shelter, which not only reduces its service life, but also seriously affects the filtration and screening of blue-green algae in rainy days
