Description

Technical Field

[0001] The utility model relates to the technical field of microalgae cultivation, in particular to a microalgae cultivation raw water filtering device. Background Art

[0002] Microalgae are a type of autotrophic organism that is widely distributed on land and in the ocean. They are rich in nutrients and have high photosynthetic utilization rates. The polysaccharides, proteins, pigments, etc. produced by cell metabolism give them great development prospects in the fields of food, medicine, genetic engineering, liquid fuels, etc.

[0003] In order to ensure a good living environment for microalgae during cultivation, it is necessary to filter the raw water. Traditional filtering methods all use industrial filters, which are connected to the cultivation pool and circulate and filter the water through a circulation pump. However, since microalgae exist in the raw water, they are easy to enter the filtering device during circulation filtration, resulting in material waste and clogging of the pipeline. Therefore, the utility model proposes a raw water filtration device for microalgae cultivation. Utility Model Content

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] A microalgae breeding raw water filtering device comprises a breeding pond body, a filter body is installed on the side wall of the breeding pond body, a connecting through hole is opened on the side wall of the breeding pond body at one end close to the filter body, the connecting through hole is communicated with the filter body, and a filter screen is arranged in the connecting through hole, a cleaning mechanism for cleaning the filter screen is arranged in the breeding pond body, the cleaning mechanism comprises a rotating rod rotatably connected to the inner wall of the breeding pond body, a rotating plate is fixedly connected to the end of the rotating rod, a groove is opened on the side wall of the rotating plate, a scraper is slidably connected to the inside of the groove, a circulating pump is installed on the filter body, and the water inlet end of the circulating pump is communicated with the filter body.

[0006] Preferably, the side wall of the scraper is elastically connected to the inner wall of the groove via a plurality of springs, and the plurality of springs are arranged at equal intervals.

[0007] Preferably, a pipe is installed at the water outlet of the circulation pump, and the end of the pipe is located above the culture pond body.

[0008] Preferably, an impeller is fixedly sleeved on the rotating rod, the impeller is located below the pipeline, and the impeller cooperates with the pipeline.

[0009] Preferably, the breeding pond body is designed to be rectangular, and walking wheels are provided at the lower end of the breeding pond body.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. By setting a filter net, the filter net is set on the side wall of the breeding pond. During the water circulation filtration process, the microalgae are blocked by the filter net in the breeding pond, so as to block the microalgae and prevent the microalgae from entering the filter body, causing the filter body to be blocked and damaged.

[0012] 2. By setting up a cleaning mechanism, during the water circulation and filtration process, the circulation pump draws raw water from the breeding pond, which is filtered by the filter body and then discharged into the breeding pond through the pipeline. During the drainage process, the water flow impacts the impeller to rotate, driving the rotating rod and the rotating plate to rotate. The rotating plate drives the scraper to repeatedly scrape the surface of the filter to clean the filter, avoiding the adsorption of microalgae on the filter, causing material waste and pipeline blockage, and affecting the water circulation and filtration effect.

The side wall of the scraper 11 is elastically connected to the inner wall of the groove 9 through a plurality of springs 10, and the plurality of springs 10 are arranged at equal intervals. By arranging a plurality of springs 10, the scraper 11 can be more closely fitted to the filter screen, so as to have a better scraping effect, and avoid the situation that the gap between the scraper 11 and the filter screen is large, resulting in poor scraping.

[0021] A pipe 3 is installed at the water outlet end of the circulation pump 6, and the end of the pipe 3 is located above the breeding pond body 1. An impeller 4 is fixedly sleeved on the rotating rod 5, and the impeller 4 is located below the pipe 3, and the impeller 4 cooperates with the pipe 3. The breeding pond body 1 is rectangular in design, and a walking wheel is provided at the lower end of the breeding pond body 1.

[0022] The filter screen is arranged on the side wall of the culture pond body 1. During the water circulation filtration process, the microalgae are blocked by the filter screen in the culture pond body 1, so as to block the microalgae and prevent the microalgae from entering the filter body 2, causing the filter body 2 to be blocked and damaged. During the water circulation filtration process, the circulation pump 6 draws the raw water in the culture pond body 1, which is filtered by the filter body 2 and then discharged into the culture pond body 1 through the pipeline 3. During the drainage process, the water flow impacts the impeller 4 to rotate, driving the rotating rod 5 and the rotating plate 7 to rotate. The rotating plate 7 drives the scraper 11 to repeatedly scrape the surface of the filter screen, so as to clean the filter screen and prevent the microalgae from being adsorbed and blocked on the filter screen, causing blockage and affecting the water circulation filtration effect.
