The utility model conveys a carrier with microalgae to be harvested attached to its upper surface to between a roller brush and a bubbling port through a first conveying device, and places the upper surface of the carrier within the roller brush range of the roller brush; the microalgae are separated from the carrier through the roller brush and the bubbling assembly, thereby realizing automatic harvesting of the microalgae, thereby reducing manual labor intensity and improving harvesting efficiency.

[0004] In the above technology, although the separation of microalgae and the carrier is achieved through the bubbling component and the roller brush, and the automatic harvesting of the microalgae is realized, the movement of the carrier driven by the roller brush in the horizontal state makes it impossible for the microalgae on the surface of the carrier to completely contact with the roller brush, resulting in poor separation effect. Therefore, a microalgae cultivation and harvesting device is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a microalgae cultivation and harvesting device, which aims to improve the problem of poor separation effect caused by incomplete contact between the roller brush and the carrier in the prior art.

The belt rotating mechanism 11 is used to drive the push block 12 to move, and the carrier 10 can be periodically driven to move by the belt rotating mechanism 11 and the push block 12. The belt rotating mechanism 11 is provided with a plurality of push blocks 12, which are used to drive the carrier 10 in the lower silo 4 to move. A brush roll 2 is rotatably connected to the inner wall of the upper end of the box body 1. The brush roll 2 is used to separate the microalgae from the carrier 10. The movement of the carrier 10 drives the rotation of the brush roll 2. The brush roll 2 is provided with two groups, and two brush rolls 2 form a group. A telescopic rod 5 is fixedly connected to the outer wall of the upper end of the box body 1. The telescopic rod 5 drives the slider 7 to move, and the microalgae are collected by the push plate 6 on the slider 7. The slider 7 is fixedly connected to the outer wall of the rear end of the telescopic rod 5. The slider 7 moves with the telescopic rod 5, driving the push plate 6 to push the microalgae to the collection bin 9.

[0032] Furthermore, the slider 7 is arranged in a C shape, and the left outer wall of the lower end of the slider 7 is slidably connected to the left inner wall of the upper end of the box body 1. The push plate 6 is rotatably connected to the inner wall of the bottom end of the slider 7. The push plate 6 moves with the slider 7. When the push plate 6 moves to the rear side of the upper end of the box body 1, the fixed block 1 8 presses against the rear end outer wall of the push plate 6, so that the push plate 6 rotates counterclockwise until the bottom end outer wall leaves the liquid level of the collected liquid in the box body 1. When the push plate 6 moves to the rear end of the lower silo 4, the fixed block 2 3 presses against the front end outer wall of the push plate 6, so that the push plate 6 rotates clockwise to a vertical state. At this time, the bottom outer wall of the push plate 6 The wall is below the level of the harvested liquid, a fixed block 8 is fixedly connected to the outer wall of the upper rear side of the box body 1, and the fixed block 8 is used to change the angle of the push plate 6, a fixed block 2 3 is fixedly connected to the outer wall of the upper rear side of the lower material bin 4, and the fixed block 23 is used to change the angle of the push plate 6, and the height of the fixed block 23 is consistent with the height of the fixed block 1 8, a bubbling port 14 is fixedly connected to the inner wall of the bottom end of the box body 1, and the bubbling port 14 bulges out the microalgae in the pores of the carrier 10 by bubbling, and a storage bin 13 is provided on the inner wall of the bottom end of the box body 1, and the storage bin 13 is used to collect the carrier 10 after the microalgae are separated.

[0033] Reference Figure 3 and Figure 4The collecting assembly includes a collecting bin 9, which is used to collect the microalgae pushed by the push plate 6, and the collecting bin 9 can be quickly disassembled. The front inner wall of the collecting bin 9 is slidably connected to the rear outer wall of the box body 1, and the upper inner wall of the collecting bin 9 is elastically connected with an insert 16 through a spring 15. The lower front outer wall of the insert 16 is inclined, and the front outer wall of the insert 16 is slidably connected to the upper inner wall of the collecting bin 9. Move the insert 16 outward to make the insert 16 leave the rear inner wall of the box body 1, and the collecting bin 9 can be lifted upward. Take it out and replace it with a new collecting bin 9 which slides into the rear end outer wall of the box body 1. The rear end outer wall of the box body 1 squeezes the lower front outer wall of the insert 16, and the insert 16 retracts to the inner wall of the collecting bin 9. When the collecting bin 9 moves to the rear end outer wall of the box body 1, the insert 16 pops out to fix the collecting bin 9 on the box body 1, and the front end outer wall of the insert 16 is slidably connected to the rear end inner wall of the box body 1. One end of the spring 15 is fixedly connected to the upper inner wall of the collecting bin 9, and the other end of the spring 15 is fixedly connected to the rear end outer wall of the insert 16.

[0034] Working principle: the harvesting liquid is injected into the box body 1, and the carrier 10 with the attached microalgae is placed into the lower bin 4, and the push block 12 is driven to move by the belt rotating mechanism 11. The push block 12 moves the carrier 10 in the lower bin 4 out, and drives the carrier 10 to slide on the inner wall of the box body 1. When passing through the brush roll 2, the movement of the carrier 10 drives the rotation of the brush roll 2, and the brush roll 2 separates the microalgae from the carrier 10. The carrier 10 passes above the bubbling port 14, and the bubbling port 14 bulges the microalgae in the pores of the carrier 10 through bubbling. Then the push block 12 pushes the carrier 10 into the storage bin 13, and the separated microalgae floats on the liquid surface. The telescopic rod 5 drives the slider 7 and the push plate 6 to move and push the microalgae into the collection bin 9. When the push plate 6 moves with the slider 7, the push plate 6 moves to the box body 1 When the upper rear side of the box body 1 is reached, the fixed block 1 8 presses against the rear end outer wall of the push plate 6, so that the push plate 6 rotates counterclockwise until the bottom outer wall leaves the liquid level of the collected liquid in the box body 1. When the push plate 6 moves to the rear end of the lower material bin 4, the fixed block 2 3 presses against the front end outer wall of the push plate 6, so that the push plate 6 rotates clockwise to a vertical state, realizing the automatic harvesting of microalgae. When the collecting bin 9 is full of microalgae, the embedded block 16 is moved outward to make the embedded block 16 leave the rear end inner wall of the box body 1, so that the collecting bin 9 can be taken out upward, and the new collecting bin 9 can be replaced and slided into the rear end outer wall of the box body 1. The rear end outer wall of the box body 1 squeezes the lower end front outer wall of the embedded block 16, and the embedded block 16 retracts to the inner wall of the collecting bin 9. When the collecting bin 9 moves to the rear end outer wall of the box body 1, the embedded block 16 pops out to fix the collecting bin 9 on the box body 1.
