Description

Technical Field

[0001] This utility model relates to the field of microalgae cultivation technology, and in particular to a deformation-resistant microalgae cultivation bag. Background Technology

[0002] As highly efficient photosynthetic organisms, microalgae require strict control over the stability and light transmittance of containers for large-scale cultivation. Traditional microalgae cultivation bags are usually made of flexible film materials, such as polyethylene or polyvinyl chloride. Although they have advantages such as low cost and good light transmittance, they have the following drawbacks in practical applications:

[0003] For example, the fully enclosed microalgae cultivation device in a vertical bag disclosed in Chinese Patent No. 202322452723.2 has no internal support, which causes the microalgae solution to easily deform and wrinkle after being bagged. The microalgae cells in the microalgae solution are trapped in the wrinkles, resulting in dead corners in the microalgae cultivation and affecting the microalgae cultivation effect.

[0004] For example, the microalgae cultivation light-transmitting membrane bag reactor frame disclosed in Chinese Patent No. 201820731382.9 has a complex external frame that is inconvenient to disassemble and assemble. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a deformation-resistant microalgae cultivation bag.

[0010] Preferably, the two ends of the burr are provided with female buckles, and the two ends of the supporting airbag are provided with male buckles, the male buckles being fastened into the female buckles.

[0011] Preferably, a connecting soft magnet is connected to the burr edge, and a fixed soft magnet is provided on the side of the supporting airbag near the burr edge, and the connecting soft magnet and the fixed soft magnet are magnetically attracted to each other.

[0012] To ensure the stability of the central fit of the support airbags, preferably, a central magnet is provided on the side of the two support airbags that are close to each other, so that they attract each other.

[0013] To facilitate control of air pressure at different locations of the support airbag, preferably, the support airbag has multiple air chambers, and the support airbag has inflation / deflation ports corresponding to the air chambers.

[0014] Preferably, the cross-section of the side of the supporting airbag away from the flash is triangular.

[0015] Preferably, the cross-section of the side of the supporting airbag away from the flash is arc-shaped.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1:

[0026] Reference Figures 1-5 A deformation-resistant microalgae cultivation bag includes a cultivation bag body 1, with edging 101 provided around the perimeter of the cultivation bag body 1, wherein reference is made to... Figure 1 The burr 101 can be provided with one set at the lower horizontal end and two sets at the vertical end, which are used to support and limit the lower end and side end of the culture bag 1. It should be noted that the upper end of the culture bag 1 should be provided with a clamping device for suspending the culture bag 1, so no extended burr 101 is provided. The burr 101 is detachably connected to the support airbag 2, which is transparent.

[0027] Among them, the side of the supporting airbag 2 away from the edge 101 is set with a high center and low ends;

[0028] After the support airbag 2 is inflated and fixed to the edge 101, it supports the side of the cultivation bag 1, improving its tensile strength. This prevents the bag from wrinkling after filling with microalgae solution. Since most of the deformation and wrinkles of the cultivation bag 1 are located in the middle, setting the support airbag 2 to be high in the middle and low at both ends can improve the tensile strength in the middle and effectively prevent the cultivation bag 1 from bending, thus improving its resistance to deformation.

[0029] The support airbags 2 are symmetrically arranged on both sides of the flash 101, so that when the support airbags 2 tend to bend or wrinkle in one direction, the structure with a high middle part and low ends on the other side can limit it. That is, the support airbags 2 at both ends work in sync, and the deformation resistance is stronger.

[0030] The two ends of the burr 101 are provided with female buckles 103, and the two ends of the support airbag 2 are provided with male buckles 203. The male buckles 203 are fastened in the female buckles 103. Through the male buckles 203 and the female buckles 103, the two ends of the support airbag 2 can be fixed on the burr 101.

[0031] A connecting soft magnet 102 is connected to the burr 101, and a fixing soft magnet 201 is provided on the side of the support airbag 2 near the burr 101. The connecting soft magnet 102 and the fixing soft magnet 201 are magnetically attracted. By setting the fixing soft magnet 201 and the connecting soft magnet 102, the middle part of the support airbag 2 can be fixed on the burr 101 to prevent the support airbag 2 from separating from the burr 101.

[0032] The method of using hard connections at both ends and soft connections in the middle can effectively prevent the thin film plastic of the cultivation bag 1 from stretching and breaking when subjected to tension under ordinary hard support, and prevent the microalgae solution from flowing out from the damaged area.

[0033] A central magnet 202 is provided on one side of the two supporting airbags 2 that are close to each other. It should be noted that the magnetic force of the central magnet 202 is greater than that of the fixed soft magnet 201, so as to improve the stability when the two supporting airbags 2 work together.

[0034] The support airbag 2 has multiple air chambers 204 inside, and the support airbag 2 has an inflation / deflation port 205 corresponding to the air chambers 204. It should be noted that the inflation / deflation port 205 is equipped with a valve core to facilitate inflation / deflation.

[0035] It should be noted that when cultivating microalgae, carbon dioxide gas needs to be added to the microalgae solution in the cultivation bag 1. The conventional method is aeration. During the aeration process, the cultivation bag 1 may shake and deform. Therefore, a pressure sensor can be installed in the gas chamber 204 to observe the deformation and stress of the cultivation bag 1 in a timely manner.

[0036] Example 2:

[0037] Reference Figure 4 A type of deformation-resistant microalgae cultivation bag, wherein the cross-section of the side of the support airbag 2 away from the burr 101 is triangular.

[0038] Example 3:

[0039] Reference Figure 5 A type of anti-deformation microalgae cultivation bag, wherein the cross section of the supporting airbag 2 away from the edge 101 is set in an arc shape, wherein the arc shape can be a circular arc or an elliptical arc.

[0040] This invention, through the provision of supporting airbags 2, can effectively prevent deformation of the cultivation bag 1. It has a simple structure, is easy to store, does not affect the light transmission of the cultivation bag 1, and improves the cultivation effect of microalgae.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
