Description

Technical Field

[0001] The utility model relates to the technical field of denitrification and denitrification composite bacterial agent cultivation, in particular to a denitrification and denitrification composite bacterial agent strain cultivation box. Background Art

[0002] Denitrification is a biological treatment technology that usually uses specific bacteria to degrade nitrogen compounds in wastewater, and the denitrification composite bacterial agent culture box is a device used to cultivate and proliferate denitrification bacteria.

[0003] After searching, the patent with announcement number CN216998394U discloses a denitrifying denitrification composite bacterial agent strain culture box, which includes a box body, a carrying plate and a culture dish placed on the top of the carrying plate. There are several carrying plates and they are slidably connected inside the box body. The carrying plates are distributed up and down. Several positioning grooves are opened on the top surface of the carrying plate. The bottom of the culture dish is fixedly connected or integrally formed with a positioning column, and the positioning column and the positioning groove cooperate with each other; a plurality of spray pipes are also arranged in the box body, and the spray pipes are located directly above the carrying plate. A plurality of spray heads are arranged at the bottom of the spray pipes, and the spray heads correspond one to one with the positioning grooves in the vertical direction.

[0004] Although the above-mentioned denitrifying denitrification composite bacterial agent culture box has a positioning column fixedly connected or integrally formed at the bottom of the culture dish to prevent the culture dish from sliding and colliding when the supporting plate is pulled out and causing the culture dish to break, oxygen will inhibit the activity of denitrifying bacteria during the denitrification reaction. The culture box lacks an oxygen inhibition mechanism, resulting in oxygen entering the culture box during the opening and closing of the box door, which will affect the reaction rate of the denitrifying bacteria and is not conducive to the cultivation and growth of denitrifying bacteria.

[0005] In view of the above problems, the utility model document proposes a denitrification and denitrification composite bacterial agent culture box. Utility Model Content

[0006] The utility model provides a denitrifying denitrification composite bacterial agent culture box, which solves the problem that the culture box in the prior art lacks an oxygen suppression mechanism, resulting in oxygen entering the culture box during the opening and closing of the box door, which affects the reaction rate of the denitrifying bacteria and is not conducive to the cultivation and growth of the denitrifying bacteria.

[0007] The utility model provides the following technical solutions:

[0008] A denitrification and denitrification composite bacterial agent bacterial culture box, comprising:

[0009] An incubator body, wherein a sealed door is rotatably mounted at the incubator opening of the incubator body, and a plurality of trays are arranged in the incubator body, and a plurality of culture dishes are placed on the trays;

[0010] The rotating assembly is arranged in the incubator body and is used to drive the tray to rotate, thereby promoting the reaction between the denitrifying bacteria and the culture solution;

[0011] The oxygen suppression component is arranged in the incubator body and is used to reduce the oxygen content in the incubator body, thereby ensuring the activity of denitrifying bacteria.

[0012] In one possible design, the rotating assembly includes a transmission rod rotatably mounted on both ends of the inner wall of the incubator body, the center rings of the plurality of trays are fixedly connected to the outer wall of the transmission rod, and a drive motor for driving the transmission rod to rotate is fixedly mounted on the top of the outer wall of the incubator body.

[0013] In a possible design, a plurality of rectangular plugs for plugging into slots at the bottom of the culture dish are fixedly arranged in a circular array on the top of the tray.

[0014] In one possible design, the oxygen suppression component includes a mounting frame fixedly arranged at the bottom of the outer wall of the incubator body, a drawer for containing oxygen absorbent is slidably connected in the mounting frame, an annular atomizing nozzle is fixedly installed at the top of the inner wall of the incubator body, a liquid pump is fixedly installed at the top of the outer wall of the incubator body, the output end of the liquid pump is connected to the input end of the annular atomizing nozzle through a first infusion tube, the input end of the liquid pump is connected to a second infusion tube, the other end of the second infusion tube passes through the bottom of the outer wall of the incubator body and is connected to a hose, and the hose extends into the drawer.

[0015] In a possible design, the bottom of the incubator body is provided with a plurality of penetration holes in a rectangular array for recovering the oxygen absorbent into the drawer.

[0016] In a possible design, an observation window is provided in the center of the sealed door, and tempered glass is embedded in the observation window.

[0017] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0018] In the present application, when in use, the driving motor is used to drive the transmission rod to rotate slowly and uniformly, thereby driving the tray to rotate. With the help of the centrifugal force generated by the rotation of the tray, the contact between the denitrifying bacteria in the culture dish and the culture solution is accelerated, thereby increasing the reaction rate of the denitrifying bacteria and the culture solution. As the tray rotates, it is also convenient for the staff to remove the culture dish inside.

[0019] Under normal conditions, the oxygen absorber in the drawer evaporates through the penetration hole and contacts with the oxygen in the incubator body, thereby suppressing the oxygen content in the incubator body and ensuring the activity of the denitrifying bacteria. When the sealed door is opened and then closed, a large amount of oxygen will flow into the incubator body. At this time, the liquid pump is started, and the liquid pump draws the oxygen absorber in the drawer through the hose and the second infusion tube, and delivers it to the annular atomizing nozzle through the first infusion tube, so that the vaporized oxygen absorber fills the incubator body, thereby quickly suppressing the oxygen content in the incubator body and preventing the oxygen brought in by the opening of the sealed door from affecting the reaction rate of the denitrifying bacteria. The oxygen absorber condensed into water droplets will return to the drawer along the penetration hole again, thereby reducing the loss of the oxygen absorber and improving the recycling rate of the oxygen absorber.

[0020] The utility model has the following beneficial effects:

[0021] The utility model provides a rotating component and utilizes the centrifugal force generated by the rotation of the tray to increase the reaction rate of the denitrifying bacteria and the culture solution, and facilitates the staff to remove the culture dish inside.

[0022] The utility model provides an oxygen suppression component and utilizes an oxygen absorber to suppress the oxygen content in the incubator body, thereby ensuring the activity of the denitrifying bacteria. The utility model also uses a liquid pump and an annular atomizing nozzle to quickly suppress the oxygen content in the incubator body, thereby preventing the oxygen brought in by opening the sealed door from affecting the reaction rate of the denitrifying bacteria.

[0023] The oxygen absorber condensed into water droplets in the utility model will return to the drawer again along the penetration hole, thereby reducing the loss of the oxygen absorber and helping to improve the recycling rate of the oxygen absorber. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0032] Embodiment 1

[0033] Please refer to Figure 1-4 , a bacterial culture box, comprising:

[0034] An incubator body 1, a sealed door 2 is rotatably mounted at the incubator opening of the incubator body 1, a plurality of trays 4 are arranged in the incubator body 1, and a plurality of culture dishes 5 are placed on the trays 4;

[0035] The rotating assembly is arranged in the incubator body 1, and is used to drive the tray 4 to rotate, thereby promoting the reaction between the denitrifying bacteria and the culture solution. The rotating assembly includes a transmission rod 8 rotatably mounted on both ends of the inner wall of the incubator body 1, and the central rings of the plurality of trays 4 are fixedly connected to the outer wall of the transmission rod 8. A driving motor 9 for driving the transmission rod 8 to rotate is fixedly mounted on the top of the outer wall of the incubator body 1. The driving motor 9 is connected to an external power supply through an external controller and energized. The driving motor 9 is used to drive the transmission rod 8 to rotate slowly and uniformly, thereby driving the tray 4 to rotate. With the help of the centrifugal force generated by the rotation of the tray 4, the contact between the denitrifying bacteria in the culture dish 5 and the culture solution is accelerated, thereby improving the reaction rate between the denitrifying bacteria and the culture solution. In addition, as the tray 4 rotates, it is also convenient for the staff to remove the inner culture dish 5;

[0036] A plurality of rectangular plugs 6 for plugging into the slots 7 at the bottom of the culture dishes 5 are fixedly arranged in a circular array on the top of the tray 4. The slots 7 and the rectangular plugs 6 are used in combination to fix the position of the culture dishes 5 to prevent the culture dishes 5 from colliding with each other during the rotation of the tray 4.

[0037] An oxygen suppression component is arranged in the incubator body 1, and is used to reduce the oxygen content in the incubator body 1, so as to ensure the activity of denitrifying bacteria. The oxygen suppression component includes a mounting frame 12 fixedly arranged at the bottom of the outer wall of the incubator body 1, and a drawer 13 for containing an oxygen absorbent is slidably connected in the mounting frame 12. An annular atomizing nozzle 10 is fixedly installed on the top of the inner wall of the incubator body 1, and a liquid pump 11 is fixedly installed on the top of the outer wall of the incubator body 1. The liquid pump 11 is connected to an external power supply through an external controller and energized. The output end of the liquid pump 11 is connected to the input end of the annular atomizing nozzle 10 through a first infusion tube 14, and the input end of the liquid pump 11 is connected to a second infusion tube 15. The other end of the second infusion tube 15 passes through the bottom of the outer wall of the incubator body 1 and is connected to a hose 17. The hose 17 is inserted into the drawer 13 so as to draw out the drawer 13 to replenish the oxygen absorbent. The bottom of the incubator body 1 is provided with a plurality of penetration holes 16 in a rectangular array for recovering the oxygen absorbent into the drawer 13;

[0038] More specifically, under normal conditions, the oxygen absorber in the drawer 13 evaporates through the penetration hole 16 and contacts with the oxygen in the incubator body 1, thereby suppressing the oxygen content in the incubator body 1 and ensuring the activity of the denitrifying bacteria. When the sealed door 2 is opened and then closed, a large amount of oxygen will flow into the incubator body 1. At this time, the liquid pump 11 is started, and the liquid pump 11 draws the oxygen absorber in the drawer 13 through the hose 17 and the second infusion tube 15, and delivers it to the annular atomizing nozzle 10 through the first infusion tube 14, so that the vaporized oxygen absorber fills the incubator body 1, thereby quickly suppressing the oxygen content in the incubator body 1 and preventing the oxygen brought in by the opening of the sealed door 2 from affecting the reaction rate of the denitrifying bacteria. The oxygen absorber condensed into water droplets will return to the drawer 13 again along the penetration hole 16, thereby reducing the loss of the oxygen absorber and improving the recycling rate of the oxygen absorber.

[0039] It should be noted that an oxygen absorber is a chemical substance used to absorb oxygen in the surrounding environment. Common oxygen absorbers include compounds such as iron oxide and copper oxide. Oxygen absorbers are usually designed in solid or liquid form. The oxygen absorber used in this application is in liquid form.

[0040] The present application can be used for the cultivation of composite denitrification bacterial agents, and can also be used in other fields applicable to the present application.
