Embodiment Construction
[0024] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.
[0025] Such as Figure 1-2 As shown in the figure, in order to clearly show the air blowing system, the filter cloth is omitted to prevent the air blowing system from being blocked. One side of the frame 4 is tightened and fixed, and the back plate 6 is closed and fixed on the other side of the frame 4 . An air blowing system is also arranged between the filter cloth and the back plate 6 . The frame 4 has a certain thickness, and the thickness is greater than the outer ...

The invention discloses an anti-blocking cyanobacteria concentration filter unit, which comprises an air blowing system, a filter cloth, a back plate and a frame closed and connected from head to tail, the surroundings of the filter cloth are tightened and fixed to one side of the frame, and the back plate is closed and fixed on the other side of the frame On the one hand, when in use, the filter cloth is inclined at an acute angle to the vertical surface, and a sump is provided on the inner side of the frame at the lower end of the filter cloth, and the two ends of the sump are connected with a diversion pipe, and after the diversion pipe leads out of the frame, it bends downward in a circular arc; The air blowing system includes an air intake pipe introduced from the side wall of the frame near the top, the air intake pipe straddles the frame, and the side of the air intake pipe facing the lower end of the frame is provided with a plurality of round holes, each of which is connected with a branch air pipe , the branch air pipes extend parallel to each other until close to the sump, the end of each branch air pipe is sealed as a blind end, and the branch air pipes are provided with a plurality of air outlets on the side facing the filter cloth. The invention cleans the filter cloth by blowing air, has high efficiency and low carbon, compact structure, and does not need to reserve cleaning space.
Description
technical field [0001] The invention relates to an anti-blocking cyanobacteria concentration filter unit, which belongs to the technical field of cyanobacteria treatment. Background technique [0002] Because of the lack of competition and inhibition of other species in the ecosystem, cyanobacteria reproduce and grow rapidly under suitable conditions of nutrition and temperature, and form large-scale algal blooms. When a large-scale cyanobacteria bloom breaks out, a large number of cyanobacteria accumulate and rot and decompose, emitting an unbearable stench, which seriously pollutes the nearshore environment; in addition, the cyanobacteria bloom also affects the safety of water supply in drinking water sources. [0003] Most cyanobacteria have air bubbles, which can make them float on the water surface to effectively use the light energy on the water surface for photosynthesis. There are many control methods for high-density cyanobacteria floating on the surface of water b...
