Description

Technical Field

[0001] The present invention belongs to the field of microbial culture, and particularly relates to an incubator for microbial detection in dairy products. Background Art

[0002] Microbial quality inspection mainly detects and analyzes the types, quantities, and characteristics of microorganisms such as bacteria, fungi, and viruses. It is widely used in multiple fields such as food, medicine, and the environment, and can ensure product safety, evaluate environmental quality, and provide important guarantees for people's health and life.

[0003] Microbial culture is usually carried out in a closed incubator to ensure the stability of the internal environment. When multiple culture plates are placed in the incubator, if you want to observe the culture plates in the lower layer of the incubator, you need to take out the lower culture plates. However, when the incubator is opened and closed, it is inevitable to affect the stability of the internal environment of the incubator, and the culture plates are inevitably oscillated during picking and placing, further affecting the balance of the culture solution and the culture medium in the culture plates. Summary of the Invention

[0005] The present invention is realized as follows: An incubator for microbial detection in dairy products includes an incubator. The incubator is rotatably connected with a door panel. The incubator is provided with a first temperature controller and a first oxygen generator. The top surface of the incubator is hermetically connected with a glass plate. A vertical driving assembly is arranged in the incubator. The vertical driving assembly is connected with a horizontal driving assembly. The horizontal driving assembly can drive the vertical driving assembly to rotate in the horizontal direction. The vertical driving assembly is connected with multiple rotating shafts. The rotating shafts are arranged in a ring around the vertical driving assembly. The vertical driving assembly can drive all the rotating shafts to rotate in the vertical direction;

[0006] Each rotating shaft is rotatably connected with a support frame. The support frame is fixedly connected with a culture tank for microbial culture. The rotating shaft is also rotatably connected with a positioning mechanism. The positioning mechanism can always apply a vertical pressure to the upper end surfaces on both sides of the culture tank. A limiting mechanism is arranged in the culture tank. The limiting mechanism can adjust the vertical position to limit the culture medium in the culture tank and stabilize the flow of the culture solution;

[0007] A sealing mechanism is arranged below the glass plate. When one of the culture tanks moves to the uppermost position, the sealing mechanism can limit and seal it.

[0008] Further technical solution: The positioning mechanism includes a rotating sleeve, a fixing plate, a first electromagnetic block, and a second electromagnetic block;

[0009] The rotating sleeve is rotatably connected to the rotating shaft. The rotating sleeve is fixedly connected with a fixing plate. The two ends of the fixing plate are fixedly connected with a first electromagnetic block. The upper end surfaces on both sides of the culture tank are fixedly connected with a second electromagnetic block. Each first electromagnetic block and a second electromagnetic block are arranged opposite to each other.

[0010] Further technical solution: Two turbidity sensors are arranged on the inner side wall of the culture tank facing the rotating shaft. The two turbidity sensors are arranged on both sides of the inner wall of the culture tank and are at the same height. The two turbidity sensors are commonly electrically connected to a PLC controller, and the PLC controller is electrically connected to the two first electromagnetic blocks.

[0011] Further technical solution: The limiting mechanism includes a frame, a filter screen, and a partition;

[0012] The frame is composed of multiple strip-shaped plates. The strip-shaped plates are vertically and crosswise arranged at equal intervals in the horizontal direction. A filter screen is arranged at the middle position in the vertical direction of the strip-shaped plates. One end of the frame is fixedly connected with a partition, and the partition is slidably and sealingly connected to the inner wall of the culture tank;

[0013] The partition is fixedly connected with a third electromagnetic block, and the fixing plate is fixedly connected with a fourth electromagnetic block. The third electromagnetic block and the fourth electromagnetic block are arranged opposite to each other.

[0014] Further technical solution: The sealing mechanism includes an electric telescopic sleeve, an air guide hole, and an electric sealing plate;

[0015] The inner top surface of the incubator is fixedly connected with a telescopic electric telescopic sleeve. The telescopic end of the electric telescopic sleeve can be sealingly connected to the side wall of the support frame. Air guide holes are formed in the side walls of the telescopic end of the electric telescopic sleeve, and electric sealing plates capable of sealing the air guide holes are fixedly arranged on one side of each air guide hole;

[0016] A second temperature controller and a second oxygen generator are arranged in the electric telescopic sleeve.

The second rotating frame is fixedly connected with a plurality of rotating shafts, and all the rotating shafts are arranged at equal intervals around the rotation center of the second rotating frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The positioning mechanism can always apply a vertical pressure to the upper end faces on both sides of the culture tank, thereby preventing the culture tank from shaking too much to both sides; at the same time, the limiting mechanism is kept at the bottom of the culture tank and separates and limits the culture medium in the culture tank, thereby preventing the culture medium in the culture tank from piling up on one side.

[0021] 2. When it is necessary to observe the microorganisms in a certain culture tank, at this time, the vertical driving assembly is used to move the culture tank to be observed to the highest position in the vertical direction. At this time, the sealing mechanism is started to seal the culture tank that has risen to the highest position, so as to observe the microorganisms in a single culture tank without opening the incubator, effectively ensuring the stability of the culture environment in the incubator.

[0022] 3. When a certain culture tank is about to rise to the highest position, at this time, the positioning mechanism is started to increase the limiting force on the upper end faces on both sides of the culture tank, thereby increasing the stability effect of the culture tank. At this time, the vertical height of the limiting mechanism is adjusted so that the limiting mechanism stabilizes the flow of the culture solution in the culture tank, further improving the stability of the culture tank during observation.

[0023] 4. During the vertical cyclic movement of the culture tank, under the long-term shaking effect, the culture medium in the culture tank gradually piles up on one side of the culture tank. At this time, the PLC controller adjusts the control current of the two first electromagnetic blocks on the upper side of the culture tank, so that the culture medium in the culture tank is distributed from the piling side to the other side. Furthermore, during the vertical cyclic movement of the culture tank, the culture media in each area of the culture tank are kept equal. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0034] As Figures 1-7 shown, a kind of incubator for microorganism detection in dairy products provided by the present invention includes an incubator 1, the incubator 1 is rotatably connected with a door panel 14, the incubator 1 is provided with a first temperature controller 9 and a first oxygen generator 10, the top surface of the incubator 1 is hermetically connected with a glass plate 13, a vertical driving assembly 4 is arranged in the incubator 1, the vertical driving assembly 4 is connected with a horizontal driving assembly 3, the horizontal driving assembly 3 can drive the vertical driving assembly 4 to rotate in the horizontal direction, the vertical driving assembly 4 is connected with a plurality of rotating shafts 15, the rotating shafts 15 are arranged in a ring around the vertical driving assembly 4, and the vertical driving assembly 4 can drive all the rotating shafts 15 to rotate in the vertical direction;

[0035] The rotating shaft 15 is rotatably connected to a support frame 5, the support frame 5 is fixedly connected to a culture tank 6 for culturing microorganisms, the rotating shaft 15 is also rotatably connected to a positioning mechanism 7, the positioning mechanism 7 can always apply a vertical pressure to the upper end faces on both sides of the culture tank 6, and a limiting mechanism 8 is arranged in the culture tank 6, and the limiting mechanism 8 can adjust its vertical position, so as to limit the culture medium in the culture tank 6 and stabilize the flow of the culture solution;

[0036] A sealing mechanism 2 is arranged below the glass plate 13. When one of the culture tanks 6 moves to the uppermost position, the sealing mechanism 2 can limit and seal it.

[0037] In this embodiment, open the door panel 14, pour the culture medium and the culture solution into each culture tank 6, then put microorganisms in each culture tank 6 for culturing, close the door panel 14, so that the culture box 1 maintains a sealed environment, and adjust the first temperature controller 9 and the first oxygen generator 10, so that the temperature and oxygen concentration in the culture box 1 are kept at constant values;

[0038] Start the horizontal driving assembly 3, the horizontal driving assembly 3 drives all the culture tanks 6 to rotate horizontally. At the same time, start the vertical driving assembly 4, so that all the culture tanks 6 move cyclically in the vertical direction. Through the cooperation of the horizontal driving assembly 3 and the vertical driving assembly 4, all the culture tanks 6 move cyclically in the culture box 1, and the microorganisms in all the culture tanks 6 are cultured at the same temperature and oxygen concentration, avoiding too large temperature difference and oxygen concentration difference between different regions in the culture box 1, which may cause different culture environments for each culture tank 6;

[0039] When the culture tank 6 moves cyclically in the vertical direction, it is easy to cause the support frame 5 to swing back and forth around the rotating shaft 15 during this process, resulting in the shaking of the culture solution in the culture tank 6 or the accumulation of the culture medium in the culture tank 6 on one side of the culture tank 6, affecting the culture environment of the microorganisms in the culture tank 6;

[0040] In this embodiment, the positioning mechanism 7 can always apply a vertical pressure to the upper end faces on both sides of the culture tank 6, so as to prevent the culture tank 6 from shaking too much to both sides; at the same time, the limiting mechanism 8 is kept at the bottom of the culture tank 6 and separates and limits the culture medium in the culture tank 6, so as to prevent the culture medium in the culture tank 6 from accumulating on one side;

[0041] When it is necessary to observe the microorganisms in a certain culture tank 6, at this time, the vertical driving assembly 4 is used to move the culture tank 6 to be observed to the highest position in the vertical direction. At this time, start the sealing mechanism 2 to seal the culture tank 6 that has risen to the highest position, so as to observe the microorganisms in a single culture tank 6 without opening the culture box 1, effectively ensuring the stability of the culture environment in the culture box 1;

[0042] When a certain culture tank 6 rises to the highest position and stops moving, at this time, the support frame 5 and the culture tank 6 here are prone to reciprocating swing around the corresponding rotating shaft 15 under the influence of inertia. At the same time, the culture solution in the culture tank 6 is prone to reciprocating shaking, increasing the difficulty of observing the microorganisms in the culture tank 6. In this embodiment, when a certain culture tank 6 is about to rise to the highest position, the positioning mechanism 7 is started at this time to increase the limiting force on the upper end surfaces on both sides of the culture tank 6, thereby increasing the stability effect on the culture tank 6. At this time, the vertical height of the limiting mechanism 8 is adjusted so that the limiting mechanism 8 stabilizes the flow of the culture solution in the culture tank 6, further improving the stability of the culture tank 6 during observation.

[0043] As Figure 4 shown, the present invention provides an incubator for detecting microorganisms in dairy products. The positioning mechanism 7 includes a rotating sleeve 71, a fixing plate 72, a first electromagnetic block 73, and a second electromagnetic block 74.

[0044] The rotating sleeve 71 is rotatably connected to the rotating shaft 15. The rotating sleeve 71 is fixedly connected with a fixing plate 72. The two ends of the fixing plate 72 are fixedly connected with first electromagnetic blocks 73. The upper end surfaces on both sides of the culture tank 6 are fixedly connected with second electromagnetic blocks 74. Each first electromagnetic block 73 and a second electromagnetic block 74 are arranged opposite to each other.

[0045] In this embodiment, the first electromagnetic blocks 73 at both ends of the fixing plate 72 are started. The two first electromagnetic blocks 73 always apply a vertical thrust to the two second electromagnetic blocks 74 on the lower culture tank 6. When the vertical driving assembly 4 drives each rotating shaft 15 to perform circular motion in the vertical direction, at this time, each support frame 5 and the culture tank 6 rotate around the rotating shaft 15 under the action of their own gravity. By the downward pressure applied by the two first electromagnetic blocks 73 on both sides of the culture tank 6, the stability of the culture tank 6 during movement can be increased, avoiding the culture tank 6 from shaking to both sides. The rotating sleeve 71 and the support frame 5 are both rotatably connected to the rotating shaft 15, which can ensure that the first electromagnetic block 73 and the second electromagnetic block 74 always remain opposite to each other in the vertical direction, so that the first electromagnetic block 73 applies a stable downward pressure to the second electromagnetic block 74.

[0046] As Figure 6 shown, the present invention provides an incubator for detecting microorganisms in dairy products. Two turbidity sensors 16 are arranged on the inner side wall of the culture tank 6 facing the rotating shaft 15. The two turbidity sensors 16 are arranged on both sides of the inner wall of the culture tank 6 and are at the same height. The two turbidity sensors 16 are commonly electrically connected to a PLC controller, and the PLC controller is electrically connected to the two first electromagnetic blocks 73.

[0047] In this embodiment, when the turbidity difference between the two turbidity sensors 16 is large, it indicates that during the vertical cyclic movement of the culture tank 6, under the long-term shaking effect, the culture medium in the culture tank 6 gradually accumulates on one side of the culture tank 6. At this time, the PLC controller adjusts the control current of the two first electromagnetic blocks 73 on the upper side of the culture tank 6, so that the control current of the first electromagnetic block 73 above the side where the culture medium in the culture tank 6 accumulates is smaller, the thrust of the first electromagnetic block 73 on the accumulated side of the culture tank 6 is smaller, and the thrust of the first electromagnetic block 73 above the other side of the culture tank 6 is larger. Thus, the other side of the culture tank 6 inclines downward, so that the culture medium in the culture tank 6 is distributed from the accumulated side to the other side. Furthermore, during the vertical cyclic movement of the culture tank 6, the culture medium in each area of the culture tank 6 is kept equal.

[0048] As Figures 5-7 shown, the present invention provides an incubator for detecting microorganisms in dairy products. The limiting mechanism 8 includes a frame 81, a filter net 82, and a partition plate 83.

[0049] The frame 81 is composed of multiple strip plates, and the strip plates are vertically and equally spaced and cross - arranged in the horizontal direction. A filter net 82 is arranged at the middle position in the vertical direction of the strip plates. One end of the frame 81 is fixedly connected with a partition plate 83, and the partition plate 83 is slidably and sealingly connected with the inner wall of the culture tank 6.

[0050] The partition plate 83 is fixedly connected with a third electromagnetic block 84, and the fixing plate 72 is fixedly connected with a fourth electromagnetic block 85. The third electromagnetic block 84 and the fourth electromagnetic block 85 are arranged opposite to each other.

[0051] In this embodiment, during the vertical cyclic movement of the culture tank 6, at this time, the fourth electromagnetic block 85 is not energized. A part of the frame 81 is fitted into the bottom of the culture tank 6, and the sealing mechanism 2 of the culture tank 6 is in contact with the bottom surface of the culture tank 6. The culture medium at the bottom of the culture tank 6 is limited and evenly distributed through the frame 81. Thus, during the vertical cyclic movement of the culture tank 6, it is avoided that the culture medium at the bottom of the culture tank 6 accumulates on one side due to the reciprocating shaking of the culture tank 6, affecting the culture environment of microorganisms in the culture tank 6.

[0052] When it is necessary to observe a certain culture tank 6, before the culture tank 6 moves to the highest position, at this time, the fourth electromagnetic block 85 is started to be energized. The fourth electromagnetic block 85 adsorbs the third electromagnetic block 84, and the third electromagnetic block 84 drives the frame 81 and the filter net 82 to move upward. At this time, under the filtering action of the filter net 82, the filter net 82 drives the microorganisms and the culture medium to move upward, so that the microorganisms and the culture medium are separated from the culture solution, facilitating the subsequent observation of the microorganisms.

[0053] During this process, the part of the frame 81 located below the filter net 82 can divide the liquid level of the culture medium, and at the same time, the filter net 82 stabilizes the flow of the liquid level of the culture medium, so as to keep the liquid level of the culture medium stable when the culture tank 6 stops moving vertically, and avoid the oscillation and sloshing of the culture medium when the culture tank 6 stops moving.

[0054] As Figure 2 shown, an incubator for microbial detection in dairy products provided by the present invention, the sealing mechanism 2 includes an electric telescopic sleeve 21, an air guide hole 22 and an electric sealing plate 23;

[0055] The inner top surface of the incubator 1 is fixedly connected with a telescopic electric telescopic sleeve 21, the telescopic end of the electric telescopic sleeve 21 can be hermetically connected with the side wall of the support frame 5, air guide holes 22 are formed in the side walls of the telescopic ends of the electric telescopic sleeve 21, and electric sealing plates 23 capable of sealing the air guide holes 22 are fixedly arranged on one side of each air guide hole 22;

[0056] A second temperature controller 11 and a second oxygen generator 12 are arranged in the electric telescopic sleeve 21.

[0057] In this embodiment, when it is necessary to observe a certain culture tank 6, move this single culture tank 6 to the highest position. At this time, start the telescopic end of the electric telescopic sleeve 21 to fit with the support frame 5 at the bottom of the culture tank 6, so that the culture tank 6 at the highest position is in an independent closed environment. At this time, without affecting the culture environment of other culture tanks 6 at all, without taking out this culture tank 6 separately, the culture environment of this culture tank 6 can be separately regulated through the second temperature controller 11 and the second oxygen generator 12; on the other hand, start the electric sealing plate 23 to release the sealing of the air guide hole 22, so that all the culture tanks 6 are in the same culture environment.

[0058] As Figure 2 shown, an incubator for microbial detection in dairy products provided by the present invention, the horizontal driving assembly 3 includes a first motor 31 and a first rotating frame 32, the first motor 31 is fixedly connected with the inner bottom surface of the incubator 1, the output shaft of the first motor 31 is fixedly connected with the first rotating frame 32, and the first rotating frame 32 is fixedly connected with the vertical driving assembly 4.

[0059] In this embodiment, start the first motor 31, the first motor 31 drives the first rotating frame 32 to rotate, and the first rotating frame 32 drives each culture tank 6 to move along a circular track in the horizontal direction through the vertical driving assembly 4.

[0060] As Figure 3As shown in the figure, a incubator for microorganism detection in dairy products provided by the present invention, the vertical driving assembly 4 includes a second motor 41 and a second rotating frame 42. The second motor 41 is fixedly connected to the first rotating frame 32. The output shaft of the second motor 41 is fixedly connected to the second rotating frame 42. The second rotating frame 42 is fixedly connected with a plurality of rotating shafts 15, and all the rotating shafts 15 are arranged at equal intervals around the rotation center of the second rotating frame 42.

[0061] In this embodiment, when the second motor 41 is started, the second motor 41 drives the second rotating frame 42 to rotate. The second rotating frame 42 drives all the rotating shafts 15 to rotate around the rotation center of the second rotating frame 42. All the rotating shafts 15 drive each culture tank 6 to move along a circular trajectory in the vertical direction.

[0062] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
