Description

Technical Field

[0001] This utility model relates to the field of microbial content detection technology, and more specifically, to a microbial content detection device. Background Technology

[0002] The presence or changes in the quantity of certain microorganisms can serve as an indicator of water pollution. Generally speaking, the more severe the water pollution, the higher the content of microorganisms tends to be. In water bodies that are severely polluted by organic matter, such as water bodies near the discharge outlets of domestic sewage or industrial wastewater, the abundance of organic matter provides ample nutrients for microorganisms, leading to their proliferation and a significantly higher number than in clean water bodies. By detecting indicators such as the total number of microorganisms and the number of heterotrophic bacteria in water samples, the degree of water pollution can be assessed to a certain extent.

[0003] For example, an existing patent (publication (announcement) number: CN222043213U) discloses a microbial content detector, which belongs to the field of microbial detection technology. It includes a base, and a support frame is assembled on one side of the upper end face of the base. It has the advantages of quantitative extraction, high accuracy, and improved detection efficiency. It ensures that the sample volume extracted each time is consistent, and increases the reliability and comparability of the final microbial detection results. When dealing with a large number of samples, compared with manual extraction, this device significantly improves work efficiency and reduces the time and cost of manual operation.

[0004] When using the above-mentioned device, the sample to be tested is loaded into the sampling container, and then quantitatively extracted and tested. However, due to the experimental requirements, after the water sample is left for a period of time, the microorganisms will be affected by gravity and directional forces, resulting in uneven distribution of microorganisms in the sampling container. This leads to a large difference in the microbial content in the extracted water sample, thus affecting the accuracy of the microbial content detection data. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a microbial content detection device to solve the problem that after water samples are left for a period of time for experimental purposes, microorganisms are affected by gravity and directional forces, resulting in uneven distribution of microorganisms in the sampling tank, causing large differences in the microbial content of the extracted water samples, thus affecting the accuracy of microbial content detection data.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a microbial content detection device, including a sampling tank, a liquid extractor on the sampling tank, the inlet end of the liquid extractor being fixedly connected to the liquid extractor, the outlet end of the liquid extractor being fixedly connected to the outlet pipe, a stirring tube being rotatably connected to the sampling tank, a support rod being fixedly connected to the outside of the stirring tube, a stirring rod being fixedly connected to the end of the support rod away from the stirring tube, a tumbling rod being slidably inserted inside the stirring tube, a support rod being fixedly connected to the outside of the tumbling rod, a tumbling frame being fixedly connected to the end of the support rod away from the tumbling rod, a sliding groove corresponding to the support rod being opened on the stirring tube, and the support rod being able to slide vertically along the sliding groove, the tumbling frame being movably sleeved on the outer surface of the stirring rod, the sampling tank also being provided with a rotating stirring assembly capable of driving the stirring rod to rotate and a lifting tumbling assembly capable of driving the tumbling frame to lift and tumble, and a plurality of agitation components capable of disturbing the water sample being evenly arranged on the tumbling frame.

[0007] Preferably, the stirring rod and the agitation assembly are arranged in a cross configuration, and there are several agitators arranged in a regular octagonal ring, with the agitators evenly distributed along the axis of the stirring rod.

[0008] Preferably, the rotary stirring assembly includes a drive motor, which is fixedly installed on the top of the measuring tank. A bevel gear one is fixedly connected to the output end of the drive motor, and a bevel gear two is fixedly installed on the outer surface of the stirring tube. The bevel gear one and the bevel gear two mesh with each other.

[0009] Preferably, the lifting and stirring assembly includes a reciprocating disc, which is rotatably connected to the top of the measuring tank and located above the drive motor. Toothed rollers are fixedly installed on both the rotating shaft of the reciprocating disc and the output shaft of the drive motor. A toothed belt is meshed between the two toothed rollers. A lifting column is fixedly installed at the eccentric part of the reciprocating disc. A transmission rod is rotatably connected to the lifting column. A cap is rotatably connected to the end of the transmission rod away from the lifting column. The bottom end of the cap is rotatably connected to the top end of the stirring rod.

[0010] Preferably, each of the agitation components includes two agitation rods, which are symmetrically and rotatably connected to the stirring frame. Agitation plates are fixedly installed on both sides of the agitation rods along their length. A protrusion is provided in the middle of the agitation rod, and an arc-shaped groove corresponding to the protrusion is provided in the stirring frame.

[0011] Preferably, the central angle of the arc groove is in the range of 30° to 60°.

[0012] Preferably, a heating wire is provided inside the stirring rod, and a temperature sensor is provided inside the measuring container.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses a rotating stirring assembly to drive the stirring rod on the stirring tube to rotate and stir. At the same time, a lifting and turning stirring assembly drives the turning frame and the stirring component on the turning rod to rise and turn and stir, so that the microorganisms in the water sample in the sampling tank are quickly and evenly distributed, thereby ensuring the accuracy of the microbial content detection data.

[0015] This invention, through the setting of the agitation component, creates resistance to the agitation plate by the water sample during the lifting and lowering of the agitation frame, causing the agitation plate on the two agitation rods to rotate and tilt. At this time, the thrust of the agitation plate on the water sample creates a turbulence effect, further accelerating the uniform mixing of microorganisms in the water sample.

[0016] This invention, through a heating wire, a temperature sensor, and an existing control module, can maintain a suitable temperature for the water sample during the stirring process, so that microorganisms can be evenly distributed within the water sample. Attached Figure Description

Detailed Implementation

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] As attached Figure 1 To be continued Figure 5 This utility model provides a microbial content detection device, including a sampling tank 1, a liquid extractor 2 on the sampling tank 1, an inlet end of the liquid extractor 2 fixedly connected to the liquid extractor 2, an outlet pipe 3 fixedly connected to the outlet end of the liquid extractor 2, a stirring tube 4 rotatably connected to the sampling tank 1, a support rod 5 fixedly connected to the outside of the stirring tube 4, a stirring rod 6 fixedly connected to the end of the support rod 5 away from the stirring tube 4, a slidably inserted stirring rod 7 inside the stirring tube 4, and a support rod fixedly connected to the outside of the stirring rod 7. 28. The end of the support rod 28 away from the stirring rod 7 is fixedly connected to the stirring frame 9. The stirring tube 4 is provided with a sliding groove 10 corresponding to the support rod 28, and the support rod 28 can slide vertically along the sliding groove 10. The stirring frame 9 is movably sleeved on the outer surface of the stirring rod 6. The measuring tank 1 is also provided with a rotating stirring component 11 that can drive the stirring rod 6 to rotate and stir, and a lifting stirring component 12 that can drive the stirring frame 9 to lift and stir. Multiple stirring components 13 that can disturb the water sample are evenly arranged on the stirring frame 9.

[0026] The liquid extractor 2 is a technology described in the aforementioned patent and will not be elaborated upon further.

[0027] Preferably, the stirring rod 6 and the agitation assembly 13 are arranged in a cross configuration, and there are several agitators 9 arranged in a regular octagonal ring, with the several agitators 9 evenly distributed along the axial direction of the stirring rod 6.

[0028] Preferably, the rotary stirring assembly 11 includes a drive motor 111, which is fixedly installed on the top of the measuring tank 1. The output end of the drive motor 111 is fixedly connected to a bevel gear 112, and a bevel gear 113 is fixedly installed on the outer surface of the stirring tube 4. The bevel gear 112 and the bevel gear 113 mesh with each other.

[0029] Among them, the drive motor 111 drives the bevel gear 112 to mesh with the bevel gear 113, which can make the stirring rod 6 on the stirring tube 4 rotate horizontally to stir the water sample in the measuring tank 1.

[0030] Preferably, the lifting and stirring assembly 12 includes a reciprocating disc 121, which is rotatably connected to the top of the measuring tank 1 and is located above the drive motor 111. Toothed rollers 122 are fixedly installed on the rotating shaft of the reciprocating disc 121 and the output shaft of the drive motor 111. A toothed belt 123 is meshed between the two toothed rollers 122. A lifting column 124 is fixedly installed at the eccentric part of the reciprocating disc 121. A transmission rod 125 is rotatably connected to the lifting column 124. A cap 126 is rotatably connected to the end of the transmission rod 125 away from the lifting column 124. The bottom end of the cap 126 is rotatably connected to the top end of the stirring rod 7.

[0031] During the rotation and stirring process of the stirring rod 6, the reciprocating plate 121 can be driven to rotate synchronously through the meshing transmission of the toothed roller 122 and the toothed belt 123. The lifting column 124 on the reciprocating plate 121 makes a circular motion, which causes the transmission rod 125 to push and pull the cap 126 up and down, causing the stirring frame 9 fixed on the stirring rod 7 to move up and down repeatedly, further stirring the water sample.

[0032] Preferably, each agitation assembly 13 includes two agitation rods 131, which are symmetrically and rotatably connected to the stirring frame 9. Agitation plates 132 are fixedly installed on both sides of the agitation rods 131 along their length. A protrusion 133 is provided in the middle of the agitation rods 131, and an arc-shaped groove 134 corresponding to the protrusion 133 is provided in the stirring frame 9.

[0033] Specifically, during the lifting and lowering of the stirring frame 9, the water sample generates resistance to the stirring plate 132, causing the stirring plate 132 on the two stirring rods 131 to rotate into an angled shape with its opening facing downwards when the stirring frame 9 rises, and conversely, the stirring plate 132 on the two stirring rods 131 opens upwards when the stirring frame 9 falls. Furthermore, the protrusion 133 combined with the arc groove 134 can limit the rotation of the stirring plate 132. The thrust of the stirring plate 132 on the water sample generates a turbulence effect, further accelerating the uniformity of the mixing of microorganisms in the water sample.

[0034] Preferably, the central angle of the arc groove 134 ranges from 30° to 60°.

[0035] Preferably, a heating wire 14 is installed inside the stirring rod 6, and a temperature sensor is installed inside the measuring container 1.

[0036] Specifically, through the heating wire 14, temperature sensor, and existing control module, the stirring rod 6 can maintain the water sample at a suitable temperature during stirring. Within a suitable temperature range, microorganisms are metabolically active and have strong motility, which is conducive to uniform distribution. If the temperature is too high or too low, the activity of microorganisms will decrease, and they may aggregate or precipitate, resulting in a decrease in uniformity. The control module can use a low-power STM32 microcontroller or a Siemens S7-200CN controller.

[0037] The working process of this utility model is as follows:

[0038] In use, the stirring rod 6 on the stirring tube 4 is rotated and stirred by the rotating stirring assembly 11. At the same time, the stirring frame 9 on the stirring rod 7 and the stirring assembly 13 are raised and lowered and stirred by the lifting and stirring assembly 12, so that the microorganisms in the water sample in the sampling tank 1 are quickly and evenly distributed. Then, the water sample in the sampling tank 1 is quantitatively extracted by the liquid extractor 2, and its microbial content is detected and analyzed.
