Description

Technical Field

[0001] The utility model belongs to the technical field of microalgae cultivation, and in particular relates to a reactor device for rapidly cultivating shellfish bait. Background Art

[0002] Microalgae are commonly used in physiological experiments on filter-feeding aquatic animals such as shellfish, and are often used as basic feed for filter-feeding aquatic animals such as shellfish.

[0003] Photobioreactors are the main engineering equipment required for microalgae cultivation and are also the main factor affecting the large-scale cultivation of microalgae. Existing photobioreactors generally set a lamp in the middle of the culture tank of the reactor to illuminate the microalgae so as to achieve the purpose of high-density cultivation of microalgae. However, since the lamp is set at the axis of the culture tank, there is no space to install a stirring rod, which is not conducive to stirring the culture solution, so that a large number of microalgae may have problems of sticking to the wall or sedimentation, affecting the efficiency of algae cultivation. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a reactor device for rapidly cultivating shellfish baits which can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a reactor device for quickly cultivating shellfish bait, comprising: a cultivation transparent tank, the opening at the upper end of the cultivation transparent tank is covered with a tank cover, and a light-emitting lamp is inserted on the tank cover, and the light-emitting lamp is located inside the cultivation transparent tank; an air pump, which is arranged below the cultivation transparent tank; a diverter plate, which rotates at the lower end of the cultivation transparent tank, and the air inlet at the lower end of the diverter plate is connected to a connecting pipe through a rotating joint, and the lower end of the connecting pipe extends downward out of the cultivation transparent tank and is connected to the air outlet of the air pump; a control box, which is arranged on one side of the cultivation transparent tank and is electrically connected to the light-emitting lamp and the air pump; an air supply pipe, which is connected to the diverter plate at equal intervals in a circle, and a plurality of the air supply pipes are provided with air jets on the same side.

[0006] In order to avoid the phenomenon of backflow of the culture fluid, the gas delivery pipe is further designed to be concave-shaped, and the bending part of the upper end of the gas delivery pipe is higher than the liquid level of the culture fluid.

[0007] In order to prevent some microalgae from entering the gas pipeline, further, a filter is fixedly connected to the air outlet of the gas pipeline.

[0008] In order to facilitate the waterproof and temperature-insulating effect on the light-emitting tube, further, a laminated glass tube is fixedly connected to the lower surface of the tank cover, and a through hole that penetrates the laminated glass tube is opened on the tank cover, and the light-emitting tube is located in the laminated glass tube.

[0009] In order to facilitate the flexible movement of the device, it further includes a mobile base bracket, and the culture transparent tank, control box and air pump are all installed on the mobile base bracket.

[0010] In order to facilitate quick placement and removal of the transparent cultivation tank, further, a T-shaped socket is fixedly connected to the bottom of the transparent cultivation tank, and a socket for use with the T-shaped socket is provided on the movable base bracket.

[0011] In order to facilitate the sterilization of the gas entering the culture solution, further, a filter box connected to the air inlet of the air pump is fixedly connected to the movable base bracket, and a sterilization filter plate is inserted in the filter box.

[0012] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model uses the connecting pipe, the rotating joint, the diverter plate, the air pipe and other components in coordination. When the air pump is started to aerate the culture solution, the air pipe will rotate under the reverse thrust of the airflow, so that the culture solution can be stirred, and the phenomenon of microalgae adhering to the wall or sinking to the bottom can be reduced, which effectively improves the cultivation effect of microalgae. At the same time, when the bubbles generated during the aeration process touch the rotating air pipe, the bubbles can also be destroyed so that the carbon dioxide in the bubbles can be just dissolved in the culture solution for absorption by the microalgae, which further improves the cultivation effect of the microalgae.

[0013] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] Embodiment 1:

[0022] Reference Figure 1-Figure 4 A reactor device for rapidly cultivating shellfish bait comprises: a cultivation transparent tank 1, wherein the opening at the upper end of the cultivation transparent tank 1 is covered with a tank cover 101, and a light-emitting lamp 201 is plugged into the tank cover 101, and the light-emitting lamp 201 is located inside the cultivation transparent tank 1; an air pump 202 is arranged below the cultivation transparent tank 1; a diverter plate 3 is rotated at the lower end of the cultivation transparent tank 1, and a connecting pipe 301 is connected to the air inlet at the lower end of the diverter plate 3 through a rotating joint, and the lower end of the connecting pipe 301 extends downward out of the cultivation transparent tank 1 and is connected to the air outlet of the air pump 202; a control box 2 is arranged on one side of the cultivation transparent tank 1 and is electrically connected to the light-emitting lamp 201 and the air pump 202; an air supply pipe 302 is connected to the diverter plate 3 at equal intervals in a circle, and a plurality of air supply pipes 302 are provided with air jets on the same side.

[0023] In the process of cultivating shellfish bait (microalgae), when it is necessary to aerate the culture solution to increase the carbon dioxide concentration in the culture solution, the air pump 202 can be started at this time, and the air pump 202 can transport gas to the diverter plate 3 through the connecting pipe 301, and then the diverter plate 3 will transport the gas into multiple gas pipes 302 respectively, and spray it out through the jet port, and then the gas can be injected into the culture solution to increase the carbon dioxide concentration in the culture solution. When the gas is sprayed through the jet port, the gas pipe 302 will rotate under the reverse thrust of the airflow, so that the culture solution can be stirred, and the phenomenon of microalgae adhering to the wall or sinking to the bottom can be reduced, which effectively improves the cultivation effect of microalgae. At the same time, when the bubbles generated during the aeration process touch the rotating gas pipe 302, the bubbles can also be destroyed, so that the carbon dioxide in the bubbles can just dissolve in the culture solution for absorption by the microalgae, further improving the cultivation effect of the microalgae.

[0024] Embodiment 2:

[0025] Reference Figure 1-Figure 4, a reactor device for quickly cultivating shellfish bait, which is basically the same as Example 1, and further: the air pipe 302 is designed to be bent in a concave shape, and the bending part of the upper end of the air pipe 302 is higher than the liquid surface of the culture solution. By designing the bending of the air pipe 302 and making the bending part of the Shandong crown of the air pipe 302 higher than the liquid surface of the culture solution, when the air pipe 302 rotates, the bubbles can be more fully dispersed, so that the carbon dioxide in the bubbles can be more fully released into the water and absorbed by the algae, and at the same time, the problem of backflow of the culture solution through the air pipe 302 can be avoided.

[0026] A filter 303 is fixedly connected to the air jet outlet of the air pipe 302. By setting the filter 303 at the air jet outlet of the air pipe 302, the algae can be blocked to prevent some algae from entering the air pipe 302, thereby affecting the adequacy of subsequent algae harvesting.

[0027] A laminated glass tube 103 is fixedly connected to the lower surface of the tank cover 101, and a through hole that penetrates the laminated glass tube 103 is opened on the tank cover 101. The light-emitting lamp 201 is located in the laminated glass tube 103. By arranging the light-emitting lamp 201 in the laminated glass tube 103, while ensuring that the algae are illuminated, not only can the light-emitting lamp 201 be waterproofed, but also the light-emitting lamp 201 can be insulated, thereby preventing the algae from dying due to the high temperature after touching the heated light-emitting lamp 201, thereby effectively improving the protection effect on the algae.

[0028] Embodiment 3:

[0029] Reference Figure 1-Figure 4 , a reactor device for rapidly cultivating shellfish bait, is basically the same as Example 2, and further includes: a movable base bracket 4, on which the cultivation transparent tank 1, the control box 2 and the air pump 202 are all installed. Through the setting of the movable base bracket 4, the device can be flexibly moved and changed in position, which effectively improves the flexibility of the device.

[0030] A T-shaped socket 102 is fixedly connected to the bottom of the cultivation transparent tank 1, and a socket for use with the T-shaped socket 102 is opened on the mobile base bracket 4. Through the setting of the T-shaped socket 102, when the cultivation transparent tank 1 is installed on the mobile base bracket 4, it can be plugged into the mobile base bracket 4 through the T-shaped socket 102. While ensuring the stability of the cultivation transparent tank 1, it is also convenient to quickly take and place the cultivation transparent tank 1, which provides convenience for subsequent harvesting.

[0031] A filter box 203 connected to the air inlet of the air pump 202 is fixedly connected to the mobile base bracket 4, and a sterilizing filter plate 204 is inserted in the filter box 203. By arranging the filter box 203 and the sterilizing filter plate 204 at the air inlet of the air pump 202, the gas entering the culture solution can be sterilized, thereby reducing the problem of algae being infected and dying.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
