Technical Field

[0001] The invention relates to the technical field of blue algae cleaning, in particular to a device for automatically shrinking spherical degradable blue algae into agglomerates. Background Art

[0002] Cyanobacteria are large single-cell prokaryotes that can carry out oxygenic photosynthesis. Cyanobacteria have diverse morphologies and exist in filamentous or non-filamentous groups. Cyanobacteria mainly reproduce through vegetative reproduction and asexual reproduction.

[0003] With the development of human society, a large amount of nutrients are discharged into water bodies, providing sufficient nutrients for the growth of cyanobacteria, resulting in a widespread explosive growth of cyanobacterial biomass and triggering a series of environmental problems. Cyanobacteria are suspended in water bodies and will float up under certain conditions and migrate and aggregate and diffuse with the water under the influence of specific hydrodynamics and wind fields. The dispersed distribution characteristics of cyanobacteria make it difficult for humans to remove cyanobacteria from water bodies by salvaging, and the cost is relatively high. Summary of the invention

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 5 , the present invention provides a technical solution: A device for automatically shrinking spherical degradable cyanobacteria into a ball comprises a first protective shell 1 and a second protective shell 11, wherein the first protective shell 1 and the second protective shell 11 constitute a sphere, wherein a filter cotton 2 is placed in the middle of the sphere constituted by the first protective shell 1 and the second protective shell 11, wherein the first protective shell 1 and the second protective shell 11 are both hollow spherical structures, and the first protective shell 1, the second protective shell 11, the support ring 6 and the connecting ring 7 are all made of environmentally friendly ABS, wherein the first protective shell 1, the connecting ring 7 and the second protective shell 11 constitute a three-dimensional structure, wherein the filter cotton 2 is made of high-density fiber, and is made of at least one degradable material selected from polylactic acid PLA, polybutylene adipate terephthalate PBAT and polyhydroxyalkanoate PHA, and nitrifying bacteria are attached to the surface of the filter cotton 2.

[0021] The adsorption effect of the hollow sphere is utilized to aggregate the cyanobacteria particles dispersed in the water body into clusters, and the tiny uncontrollable migrating and diffusing cyanobacteria are aggregated into large clusters for easy salvage and recovery. The high-density fiber gap filter cotton is a degradable material and is deployed in waters where cyanobacteria are prone to gather. After being captured, the cyanobacteria have a short life cycle and are easy to gather and die. When there are only a small amount of cyanobacteria, there is no need to recycle them. They can be degraded in the non-cyanobacteria season and will not affect the environment while controlling the cyanobacteria.

[0022] A connecting ring 7 is installed on the side of the second protective shell 1 close to the first protective shell 1 , and a mounting ring 8 is installed on the side of the first protective shell 1 close to the second protective shell 11 . The inner side of the connecting ring 7 and the outer side of the mounting ring 8 are connected by threads, and the width of the mounting ring 8 is smaller than that of the connecting ring 7 .

[0023] The first protective shell 1 and the second protective shell 11 are stably installed through the threaded setting, the filter cotton 2 is limited, and the threaded connection method is convenient for installing and disassembling the shrinking and balling device, and it is convenient to replace the filter cotton 2 inside the shrinking and balling device.

[0024] A rotating rod 12 is installed at the bottom end of the connecting ring 7 , and a supporting ring 6 is installed at the other end of the rotating rod 12 . The supporting ring 6 is sleeved on the outside of the connecting ring 7 .

[0025] An inner airbag 5 is installed on the outside of the support ring 6, and an outer airbag 3 is installed on the outside of the inner airbag 5. The outer airbag 3 and the inner airbag 5 are both filled with air. An air guide tube 4 is installed on the outside of the outer airbag 3, and a one-way valve 9 is installed on the air guide tube 4. The air guide tube 4 is an "L"-shaped structure. The exhaust direction of the air guide tube 4 is the tangential direction of the outer airbag 3. The air guide tube 4 is composed of at least two parts.

[0026] The one-way valve 9 is opened, and the gas inside the outer air bag 3 escapes through the air guide tube 4 through the one-way valve 9. The reaction force of the gas drives the overall rotation, so that the shrinking and balling device rotates on the horizontal plane. The diameter of the air guide tube 4 is set to be smaller, so that the gas inside the outer air bag 3 can escape slowly. The setting of the inner air bag 5 can make the shrinking and balling device float on the water surface, and can absorb the blue algae floating on the water surface.

[0027] A waterproof motor 10 is installed on a side of the support ring 6 away from the rotating rod 12 , and an output end of the waterproof motor 10 is fixed to the top end of the connecting ring 7 .

[0028] The waterproof motor 10 runs, and the waterproof motor 10 drives the shrinking and agglomerating device to rotate. The rotation of the shrinking and agglomerating device drives the rotating rod 12 to rotate synchronously, thereby causing the shrinking and agglomerating device to rotate up and down. The shrinking and agglomerating device can rotate up and down at the same time during the circumferential rotation. The filter cotton 2 inside the automatic shrinking and agglomerating device can be adsorbed to blue algae on all sides through the rotation, so that the filter cotton 2 can be fully attached, thereby improving the shrinkage efficiency of the automatic shrinking and agglomerating device.
