Description

Technical Field

[0001] The utility model belongs to the technical field of spirulina harvesting, and particularly relates to a spirulina collecting device. Background Art

[0002] Spirulina belongs to the Cyanobacteria, Cyanobacteria, Oscillatoriaceae and Spirulina genus. It is an ancient lower prokaryotic single-cell or multi-cell aquatic plant. It is shaped like a clockwork and is spiral blue-green in color, so it is also called blue-green algae. Spirulina is the most nutrient-rich and comprehensive organism in nature. Spirulina is rich in high-quality protein, linolenic acid fatty acids, carotenoids, vitamins, and various trace elements such as iron, iodine, selenium, zinc, etc. Spirulina has been found to have various pharmacological effects, such as lowering blood lipids, anti-oxidation, anti-infection, anti-cancer, anti-radiation, anti-aging, and enhancing the body's immunity. Spirulina is one of the microalgae produced on a large scale industrially and needs to be harvested after the spirulina is harvested.

[0003] In the prior art, spirulina is collected by using a water pump to pump water from a spirulina pool into a 300-400 mesh filter for separation. The water then flows back into the algae cultivation pool, leaving spirulina and other impurities on the filter. The collected spirulina has a low purity, and the water pump can damage the spirulina, causing the nutrients in the spirulina to precipitate.

[0004] At night, when the spirulina pool is undisturbed, the spirulina tends to float on the surface while other substances settle at the bottom. This phenomenon can be exploited to collect the spirulina and improve its purity. Therefore, in order to improve the efficiency and purity of spirulina collection and avoid damage to the spirulina during the collection process, a spirulina collection device is urgently needed.

The following describes an embodiment of the present invention based on its overall structure.

[0028] Example

[0029] like Figures 1 to 3 As shown, a spirulina collecting device includes a spirulina cultivation pond 100, and a harvesting device 200 is installed on the side of the spirulina cultivation pond 100;

[0030] Preferably, the harvesting device 200 includes a driving conveying group 210, a driven receiving group 220 and a filter 230. The opposite ends of the spirulina cultivation pond 100 are set as the delivery end and the receiving end. Two groups of the driving conveying groups 210 are relatively mounted on opposite sides of the spirulina cultivation pond 100 and are located at the delivery end of the spirulina cultivation pond 100; two groups of the driven receiving groups 220 are relatively mounted on opposite sides of the spirulina cultivation pond 100 and are located at the receiving end of the spirulina cultivation pond 100; the driving conveying group 210 and the driven receiving group 220 are connected by a linkage chain 300, and a plurality of connecting rods 400 are provided between the linkage chains 300. The filter 230 is hung on any of the connecting rods 400.

[0031] By driving the driving conveying group 210 to lay the filter screen 230 from the feeding end of the spirulina cultivation pond 100 to the receiving end, until the entire pool surface of the spirulina cultivation pond 100 is laid, the driving conveying group 210 and the driven receiving group 220 are driven to lift the filter screen 230 from the bottom of the pool surface, and the spirulina and the aquaculture water are separated as much as possible through the filter screen 230. The aquaculture water is filtered and returned to the aquaculture pond, and the remaining spirulina remains on the filter screen 230 (in order to ensure the filtration efficiency). The filter screen 230 is a 300-400 mesh screen), and the driving and conveying group 210 is driven in reverse to retract the filter screen 230 from the receiving end to the delivery end, wherein a scraping bar 500 is provided between the two groups of the driving and conveying groups 210, and a material receiving chute 600 is provided at the delivery end of the spirulina cultivation pond (100). During the recovery process of the filter screen 230, the spirulina is scraped uniformly onto the material receiving chute 600 by the scraping bar 500, thereby completing the harvesting of the spirulina in the entire pond.

[0032] It is worth mentioning that, since the spirulina water body is not stirred at night, the spirulina floats on the surface of the algae-growing water body, while other substances in the algae-growing water body settle to the bottom of the pool. Before driving the filter screen 230 to be laid, the driving conveying group 210 and the driven receiving group 220 are first driven to sink with the linkage chain 300 to a place 20-30 mm away from the pool surface. Since the driving conveying group 210 and the driven receiving group 220 are small in size, the disturbance to the spirulina during the sinking process is negligible. After the driving conveying group 210 and the driven receiving group 220 have sunk, the filter screen 230 is hung on the connecting rod 400. On the top, the driving conveying group 210 is driven to drive the transmission of the linkage chain 300 to complete the flattening of the filter screen 230. At this time, the scraping bar 500 can also limit and suppress the filter screen 230, so that the filter screen 230 is always flat with the linkage chain 300 and will not tilt at an angle during the delivery process to affect the collection of spirulina. After the filter screen 230 is flattened, the driving conveying group 210 and the driven receiving group 220 are driven to lift the filter screen 230. At this time, the spirulina floating on the pool surface can be harvested. This harvesting method can ensure the purity of the harvested spirulina and improve the efficiency of the harvest.

[0033] In some preferred embodiments, the driving and conveying group 210 includes a mounting base 211, a lifting mounting base 212, a telescopic cylinder 213, a driving motor 214, a cantilever mounting plate 215, a driving bevel gear 216, a driven bevel gear 217, a rotating shaft 218 and a sprocket 219. The mounting base 211 is provided with a slide groove 1, and the lifting mounting base 212 is slidably arranged in the slide groove 1. The telescopic cylinder 213 is installed on the mounting base 211, and the output end of the telescopic cylinder 213 is connected to the The lifting mounting seat 212 is connected, the driving motor 214 is installed on the lifting mounting seat 212, the cantilever mounting plate 215 is installed on the lifting mounting seat 212, the rotating shaft 218 is rotatably installed on the cantilever mounting plate 215, one end of the rotating shaft 218 is installed with the sprocket 219, and the other end is installed with the driven bevel gear 217, the output end of the driving motor 214 is provided with the driving bevel gear 216, and the driving bevel gear 216 is meshed and connected with the driven bevel gear 217. Similarly, the driving and conveying group 210 includes a mounting base 211, a lifting mounting base 212, a telescopic cylinder 213, a driving motor 214, a cantilever mounting plate 215, a driving bevel gear 216, a driven bevel gear 217, a rotating shaft 218 and a sprocket 219. The mounting base 211 is provided with a slide groove 1, and the lifting mounting base 212 is slidably arranged in the slide groove 1. The telescopic cylinder 213 is installed on the mounting base 211, and the output end of the telescopic cylinder 213 is connected to the lifting mounting base. The first mounting base 212 is connected to the first lifting mounting base 212. The drive motor 214 is mounted on the first lifting mounting base 212. The first cantilever mounting plate 215 is mounted on the first lifting mounting base 212. The first rotating shaft 218 is rotatably mounted on the first cantilever mounting plate 215. The first rotating shaft 218 is mounted on one end of the first rotating shaft 218 and the second end of the first rotating shaft 218 is mounted on the second cantilever mounting plate 215. The output end of the drive motor 214 is provided with the driving bevel gear 216, which is meshed with the driven bevel gear 217. The linkage chain 300 is mounted on the first sprocket 219 and the second sprocket 226. The drive of the drive motor 214 drives the rotation of the driving bevel gear 216. Since the driving bevel gear 216 meshes with the driven bevel gear 217, the linkage chain 300 is driven on the gears, thereby driving the filter screen 230 to be laid flat. Before tiling, the linkage chain 300 is driven by the telescopic cylinder 1 213 and the telescopic cylinder 2 223 to sink to a position 20-30 mm below the pool surface. At this time, the scale lines set on the sides of the chute 1 and the chute 2 can be used for reading and judgment.

[0034] In summary, the utility model provides a spirulina collection device, which collects spirulina by an automatic salvaging and filtering method according to the growth habits of spirulina. At the same time, the collection device can also adjust the sinking depth, thereby ensuring the quality of spirulina collection and improving the collection efficiency.
