Description

Technical Field

[0001] This utility model relates to the field of microalgae cultivation technology, and in particular to a microalgae photobioreactor device. Background Technology

[0002] Microalgae are considered an exciting source of plant protein and nutrients in food supplements, offering health benefits. Microalgae are very common in nature, and industrial farming is an efficient large-scale production method. Photobioreactors (PBRs) can produce stable, high-quality, uncontaminated microalgae in large quantities.

[0003] Existing microalgae photobioreactors use a motor to rotate gears, which in turn rotates a ring rack. This causes the moving ring to rotate, resulting in two lamps rotating at a constant speed around the culture tube. When the lamps are activated, they emit light onto the culture tube, providing illumination for microalgae cultivation. However, after prolonged use, dust accumulates on the surface of the culture tube, blocking the light from penetrating the tube and illuminating the microalgae, thus reducing the light intensity. Utility Model Content

They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Given that in current technology, after prolonged use, dust accumulates on the surface of the culture tube, thus blocking the light from penetrating the culture tube to irradiate the microalgae and reducing the light intensity of the lamp.

[0026] like Figure 1-3As shown, this utility model embodiment provides a microalgae photobioreactor device, including: a photoreaction component 1, which includes: a glass tube 12 disposed on the top of a base 11; a rotating component 13 disposed on the outer bottom of the glass tube 12; a spiral lamp tube 14 disposed on the rotating component 13 and located on the outer side of the glass tube 12; a cleaning component 2 disposed on the rotating component 13 and located between the upper and lower ends of the spiral lamp tube 14, the cleaning component 2 including: a support plate 21 disposed on the rotating component 13 and located between the upper and lower ends of the spiral lamp tube 14; a threaded rod 22 passing through the support plate 21 and threadedly connected to the support plate 21; a cleaning sponge 23 disposed at one end of the threaded rod 22; a limiting rod 24 symmetrically disposed on one side of the cleaning sponge 23; a through groove 241 on the support plate 21 that cooperates with the limiting rod 24; and a spray head 25 disposed on the top of the base 11 and located on one side of the glass tube 12.

[0027] In use, the rotating assembly 13 and the spiral lamp tube 14 are activated. The rotating assembly 13 pushes the spiral lamp tube 14 to rotate and irradiate the microalgae inside the glass tube 12 evenly. When it is necessary to clean the outer wall of the glass tube 12, the spray head 25 is activated to spray cleaning solution onto the outer wall of the glass tube 12, and the threaded rod 22 is rotated. The rotating threaded rod 22, together with the limiting rod 24, pushes the cleaning sponge 23 to fit tightly against the outer wall of the glass tube 12. At the same time, the rotating assembly 13, through the support plate 21, pushes the cleaning sponge 23 to work with the spray head 25 to clean the outer wall of the glass tube 12, which facilitates the cleaning of the outer wall of the glass tube 12, increases the cleaning effect of the outer wall of the glass tube 12, and ensures the irradiation intensity of the spiral lamp tube 14 on the microalgae.

[0028] Specifically, the rotation mechanism of the spiral lamp tube is existing technology. The spiral lamp tube has a metal contact (such as a spring pin) at the top rotating joint and is located in the slide rail 151. Current is conducted through physical contact, without the need for wires to directly participate in the rotation. This section is not shown in the attached drawings of the instruction manual.

[0029] Furthermore, a threaded sleeve 26 is fitted on the outer side of the threaded rod 22 and is located on one side of the support plate 21. When the threaded rod 22 is rotated so that the cleaning sponge 23 is pressed tightly against the outer wall of the glass cylinder 12, the threaded sleeve 26 is rotated. The rotating threaded sleeve 26 moves and squeezes to one side of the support plate 21, thereby squeezing and fixing the threaded rod 22.

[0030] Furthermore, a compression plate 27 is provided on one side of the threaded sleeve 26 and is sleeved on the outside of the threaded rod 22, which increases the area of ​​the compression support plate 21 on one side of the threaded sleeve 26 and improves the stability of the compression and fixing of the threaded rod 22.

[0031] Furthermore, an anti-slip pad 271 is provided between the extrusion plate 27 and the support plate 21, which increases the anti-slip properties of the extrusion plate 27 pressing the support plate 21 on one side.

[0032] Specifically, the extrusion plate 27 is a circular iron sheet, and the anti-slip pad 271 is a rubber ring.

[0033] Furthermore, Velcro 28 is provided between the brush plate and the sponge on the cleaning sponge 23, so that the brush plate and the sponge on the cleaning sponge 23 can be glued together, making it convenient to disassemble, clean and replace the sponge on the brush plate of the cleaning sponge 23.

[0034] Furthermore, a limit plate 242 is provided at one end of the limit rod 24 to limit the limit rod 24 and prevent the limit rod 24 from detaching from the support plate 21.

[0035] Specifically, the limiting rod 24 is in the shape of a stainless steel cylinder, and the limiting plate 242 is in the shape of a stainless steel disc.

[0036] Furthermore, the rotating assembly 13 includes: a rotating base 131 disposed at the bottom outer side of the glass tube 12; a motor 132 disposed at the top of the base 11, the output end of the motor 132 being provided with a gear 133 that engages with the rotating base 131 and is rotatably connected to the rotating base 131, the motor 132 is rotary started, the motor 132 drives the gear 133 to rotate, and the rotating gear 133 drives the spiral lamp tube 14 and the support plate 21 to rotate.

[0037] Specifically, the cleaning fluid mist and cleaning waste liquid sprayed from the spray head 25 will not affect the normal operation of the motor 132 and gear 133.

[0038] Furthermore, a pulley 15 is provided on the top of the support plate 21, and a slide rail 151 that matches the pulley 15 is provided on the outer side of the top of the base 11, supporting the support plate 21 and the spiral lamp tube 14, which increases the stability of the rotating gear 133 driving the spiral lamp tube 14 and the support plate 21 to rotate.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
