Description
Technical Field
[0001] The utility model relates to the technical field of sample bottles, in particular to a magnetic stirring sample bottle. Background Art
[0002] This technology relates to the sample bottles used in water quality detection, which are applied to provide a detection source for on-line monitor equipment after water sample collection. At present, during the water sample detection process, the on-line monitor only directly extracts a certain volume of water sample through a water sampling pipe and enters the on-line monitoring equipment for detection. However, according to the specified manual detection method, it is necessary to manually shake the water sample to mix it evenly and then extract a certain volume of the detection liquid for the detection process. At present, the on-line monitor equipment does not have the function of stirring and mixing, resulting in a large deviation between the data of the on-line monitor and the data obtained by manual monitoring. Especially during the sample detection process in a sewage treatment plant, the samples in the sewage treatment plant are complex and have a high concentration. If the samples are not uniform enough before entering the on-line monitor, it will lead to a large deviation between the detection results and the actual state of the water sample. Therefore, how to improve the structure of the sample bottle without changing the on-line monitor equipment so that the samples supplied by the sample bottle to the on-line monitor are evenly mixed. Content of the Utility Model
[0003] To provide an improved solution for a sample bottle to enable the sample bottle to mix the samples in the bottle evenly and then supply them to the on-line monitor.
[0004] To achieve the above object, the utility model provides the following technical solution: A magnetic stirring sample bottle, comprising a sample bottle and a bottle cap cooperating with the sample bottle. The bottle cap is provided with a sampling pipe, and the sampling pipe communicates the inside of the sample bottle and the on-line monitor. The sample bottle includes an outer bottle and an inner bottle. The inner bottle can be sleeved inside the outer bottle, and the height of the outer bottle is greater than that of the inner bottle. A magnetic rotor is provided at the inner bottom of the inner bottle, and the outer bottom of the inner bottle is rotatably connected with a magnetic drive. The outer diameter of the magnetic drive is smaller than the outer diameter of the inner bottle. The magnetic drive is connected to a motor, and the motor is arranged inside the bottom of the outer bottle. The outer bottle includes an outer bottle mouth thread and an outer bottle bottom. The outer bottle mouth thread is located outside the bottle mouth of the outer bottle and is rotationally matched with the bottle cap. The outer bottle bottom is detachably connected to the side of the outer bottle.
[0005] Preferably, a motor seat is provided on the upper part of the outer bottle bottom. The motor seat is in a groove shape, and the motor is placed in the groove of the motor seat. The motor shaft of the motor is connected to the center of the magnetic drive.
[0006] Preferably, a limiting plate is provided on the outer bottom of the inner bottle, and the magnetic drive is arranged inside the limiting plate and can rotate relative to the limiting plate.
[0007] Preferably, a motor knob is provided on the outer side of the outer bottle, and the motor knob controls the motor through a cable.

The liquid outlet end of the sampling tube is communicated with the first sampling tube, and the liquid outlet ends of the sampling tubes are all communicated.
[0009] Compared with the prior art, the utility model provides a magnetic stirring sample bottle, which has the following beneficial effects: The sampling device of the utility model uses the principle of magnetic stirring to mix the water sample, which better improves the data deviation caused by the uneven samples collected by the on-line monitor. The sample bottle of the utility model is especially suitable for containing water samples with complex components, large suspension and high concentration in sewage treatment plants, so that a certain volume of samples extracted by the on-line monitor are evenly mixed. At the same time, the deviation between the data of the on-line monitor and the manual monitoring data is reduced, and the accuracy of the detection result is guaranteed. The way of sleeving the inner bottle and the outer bottle, combined with the detachable bottle bottom at the bottom of the outer bottle, can separately take out the inner bottle, making it more convenient to clean the inner bottle.

Detailed Embodiments
[0012] Next, the technical solutions in the embodiments of the utility model will be described in conjunction with the drawings in the embodiments of the utility model:
[0013] The sampling bottle of the utility model is mainly used for the collection and detection of samples in sewage treatment plants. The samples in sewage treatment plants are complex, have a large concentration, and have a lot of suspended matter. The existing sample bottle is just a simple bottle and does not have the function of stirring and mixing the samples. The uneven samples given to the on-line monitor result in a large deviation between the obtained data and the actual situation; while manual detection can make the samples have a certain degree of uniformity, but there is still a deviation between the data of the on-line monitor and the manual data.
[0014] The utility model transforms the existing sample bottle by using the principle of magnetic stirring. After transformation, it becomes a sampling bottle capable of mixing water samples. As shown in the figure, the magnetic stirring sample bottle of the utility model includes a sample bottle 1 and a bottle cap 4 that cooperates with the sample bottle 1. The bottle cap 4 is provided with a sampling tube. Multiple sampling tubes can be provided to perform detections of different modules. The sample bottle 1 includes an outer bottle 2 and an inner bottle 3. The inner bottle 3 can be sleeved inside the outer bottle 2 and the height of the outer bottle 2 is greater than that of the inner bottle 3. The outer bottle 2 includes an outer bottle mouth thread 21 which is located on the outer side of the bottle mouth of the outer bottle 2 and is rotationally matched with the bottle cap 4. In this embodiment, two sampling tubes are taken as an example. The sampling tubes include a sampling tube one 41 and a sampling tube two 42. The inner bottle 3 is provided with a sampling tube 31. The liquid inlet end of the sampling tube 31 is close to the bottom of the inner bottle 3. The liquid outlet end of the sampling tube 31 is communicated with the sampling tube one 41 and the liquid outlet ends of the sampling tube 31 are all communicated. A magnetic rotor 6 is provided at the bottom inside of the inner bottle 3. The magnetic rotor 6 is shuttle-shaped and is located at the center of the bottom of the inner bottle 3. The bottom of the inner bottle 3 is made of a magnetic conductive material. A point contact is formed between the magnetic rotor 6 and the bottom of the inner bottle 3. The magnetic rotor 6 is driven to rotate by a magnetic drive 5. The magnetic drive 5 is arranged outside the bottom of the inner bottle 3 and can rotate relative to the inner bottle 3. The outer diameter of the magnetic drive 5 is smaller than the outer diameter of the inner bottle 3. In this way, the magnetic force of the magnetic drive 5 on the inner bottle 3 is concentrated within the cross-section of the inner bottle 3. A limiting plate 32 is provided outside the bottom of the inner bottle 3. The magnetic drive 5 can be arranged inside the limiting plate 32 and can rotate relative to the limiting plate 32. The limiting plate 32 is set according to the shape of the magnetic drive 5. The limiting plate 32 is used to limit the maximum rotation range of the magnetic drive 5 and prevent the magnetic drive 5 from exceeding the projection area of the inner bottle 3. After the magnetic drive 5 is driven by the motor 26 to rotate, the motor 26 is arranged inside the bottom of the outer bottle 2. The outer bottle bottom 22 is detachably connected to the side of the outer bottle 2. The outer bottle bottom 22 is concave. The inner wall of the concave side has an internal thread. The part of the side of the outer bottle 2 that cooperates with the outer bottle bottom 22 has an external thread. The internal thread and the external thread complete the detachable connection between the outer bottle bottom 22 and the side of the outer bottle 2.
[0015] An upper part of the outer bottle bottom 22 is provided with a motor seat 25. The motor seat 25 is in a groove shape. The motor 26 is placed in the groove of the motor seat 25. The motor seat 25 realizes the limiting function for the motor 26. The motor shaft 27 of the motor 26 is connected to the center of the magnetic drive 5. After the motor 26 is started, the motor shaft 27 rotates rapidly to drive the magnetic drive 5 to rotate as well. The magnetic force between the magnetic drive 5 and the magnetic rotor 6 causes the magnetic rotor 6 to rotate. The rapid rotation of the magnetic rotor 6 mixes the samples inside the inner bottle 3. To facilitate the experimenter to control the start and stop of the motor 26, a motor knob 23 is provided on the outer side of the outer bottle 2. The motor knob 23 controls the motor 26 through a cable 24. The cable 24 penetrates through the side wall of the outer bottle 2.
[0016] In use, place the sample bottle 1 containing the sample at the detection position of the on-line monitor. Connect the first sampling tube 41 and the second sampling tube 42 to the detection module of the on-line monitor. Start the motor knob 23, and the motor rotating shaft 27, the magnetic drive 5 and the magnetic rotor 6 rotate synchronously. After the magnetic rotor 6 mixes the sample evenly, start the on-line monitor. After the sample bottle is used once, it usually needs to be cleaned. Since the inner bottle 3 and the outer bottle 2 are sleeved, only the inner bottle 3 needs to be taken out of the outer bottle 2. Unscrew the outer bottle bottom 22 from the outer bottle 2, separate the motor rotating shaft 27 from the magnetic drive 5, or tilt the magnetic drive 5 and take it out of the limit plate 32, and then take out the inner bottle 3 from the bottom of the outer bottle 2 for cleaning.
[0017] Since the sample bottle of the present utility model can mix the sample evenly, the detection liquid fed to the on-line monitor is uniform, and the obtained detection data is closer to the actual situation, reducing the deviation from the manual detection result and ensuring the reliability of the detection result.
[0018] The above embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
