Description

Technical Field

[0001] This utility model relates to the field of potassium fertilizer concentration identification technology, and in particular to an online automatic sampling concentration identification system for potassium fertilizer. Background Technology

[0002] After potassium fertilizer is extracted, due to its high concentration, it will quickly crystallize and separate into layers in a saturated state. This separation, occurring after a certain period, allows for the determination of the potassium fertilizer concentration. The potassium fertilizer solution in a saturated state crystallizes and separates into layers; at this point, a visual recognition system can automatically identify the potassium fertilizer concentration.

[0003] Currently, potash fertilizer sampling is mainly done manually. However, the large number of potash fertilizer ponds to be sampled results in a high sampling frequency, reducing work efficiency. Utility Model Content

[0004] Therefore, there is a need for an online automatic sampling concentration identification system for potash fertilizer to address the technical problem that current potash fertilizer sampling mainly relies on manual sampling. However, the large number of potash fertilizer tanks to be sampled results in a high sampling frequency, reducing work efficiency.

[0005] To achieve the above objectives, this utility model provides an online automatic sampling concentration identification system for potassium fertilizer, comprising:

[0006] The testing container is equipped with a main liquid inlet.

[0007] The liquid inlet module includes two or more first liquid inlet pipes and two or more sampling pumps. Each first liquid inlet pipe is equipped with a sampling pump. The liquid inlet of the first liquid inlet pipe is used to connect with an external sampling pool, and the liquid outlet of the first liquid inlet pipe is connected with the main liquid inlet.

[0008] The camera module includes a camera, with the camera lens pointed at the detection container;

[0009] The cleaning module includes a main cleaning pipe, a main cleaning valve, and two or more cleaning branch pipes. The inlet of the main cleaning pipe is connected to the external tap water supply. The main cleaning valve is installed at the outlet of the main cleaning pipe. The inlets of the two or more cleaning branch pipes are connected to the main cleaning pipe. The outlet of each cleaning branch pipe is connected to the cleaning port of a first liquid inlet pipe.

[0010] Unlike existing technologies, the above-mentioned technical solution is equipped with two or more first inlet pipes and corresponding sampling pumps. This allows for the sequential entry of potash fertilizer samples from different sampling pools into the detection container for photographic testing. The automated control is more intelligent, reduces manual intervention, and improves sampling efficiency. Furthermore, a cleaning module is included to clean the inlet pipes and sampling pumps, preventing blockages caused by potash fertilizer crystallization after prolonged use.

[0011] As one embodiment of this utility model, the cleaning module also includes two or more cleaning branch valves, with one cleaning branch valve installed on each cleaning branch pipe, and the cleaning branch valve controls the corresponding cleaning branch pipe to be opened or closed.

[0012] Thus, by setting a corresponding cleaning branch valve on each cleaning branch pipe, the cleaning branch pipe can be cleaned selectively.

[0013] As one embodiment of this utility model, the testing container is also provided with a main rinsing port, and the cleaning module also includes a rinsing pipe and a rinsing valve. The inlet of the rinsing pipe is connected to the main cleaning pipe, the outlet of the rinsing pipe is connected to the main rinsing port, and the rinsing valve is installed on the rinsing pipe to control the rinsing pipe to open or close.

[0014] Thus, by setting up flushing pipes and flushing valves, the testing container can be cleaned promptly after each potash fertilizer sample test, preventing residual liquid from affecting the testing of subsequent samples. Furthermore, a final flush can be performed after all potash fertilizer samples have been tested, without affecting the next test.

[0015] As one embodiment of this utility model, the bottom of the detection container is provided with a main drain port. The online automatic sampling concentration identification system for potassium fertilizer also includes a drain module, which includes a drain pipe and a drain valve. The inlet of the drain pipe is connected to the main drain port, and the outlet of the drain pipe is used to connect to an external return pool. The drain valve is installed on the drain pipe and controls the drain pipe to open or close.

[0016] In this way, by setting up a drainage module, the potash fertilizer liquid that has been tested can be drained, making it easier to put other potash fertilizer samples to be tested into the testing container for subsequent testing.

[0017] As one embodiment of this utility model, the detection container is also provided with a total overflow port. The online automatic sampling concentration identification system for potassium fertilizer also includes an overflow pipe. The inlet of the overflow pipe is connected to the total overflow port, and the outlet of the overflow pipe is used to connect to an external return pool.

[0018] In this way, by setting an overflow pipe, the liquid level can be automatically maintained to prevent liquid backflow.

[0019] As one embodiment of the present invention, the liquid inlet module further includes a liquid inlet container and a second liquid inlet pipe. The liquid inlet container has two or more first liquid inlets and one first liquid outlet. The liquid outlet of each first liquid inlet pipe is connected to a first liquid inlet, the first liquid outlet is connected to the liquid inlet of the second liquid inlet pipe, and the liquid outlet of the second liquid inlet pipe is connected to the main liquid inlet.

[0020] In this way, by setting up an inlet container as a transition container, the number of inlets on the detection container can be reduced, without affecting the detection and extending the service life of the detection container.

[0021] In one embodiment of this utility model, the camera module also includes a light source, which is installed at a position relative to the camera, and the detection container is located between the light source and the camera.

[0022] In this way, by setting a light source, a backlight effect can be generated, thereby improving the accuracy of liquid turbidity identification and detection.

[0023] As one embodiment of this utility model, the camera module also includes a camera bracket, a vertical linear guide rail and a horizontal linear guide rail. The vertical linear guide rail is mounted on the camera bracket, the horizontal linear guide rail is mounted on the vertical linear guide rail, and the camera is mounted on the horizontal linear guide rail.

[0024] The horizontal linear guide rail drives the camera to move horizontally, while the vertical linear guide rail drives the camera to move vertically.

[0025] In this way, by setting vertical and horizontal linear guide rails, three-dimensional spatial position adjustment can be achieved, thereby adapting to different liquid level heights and observation angles.

[0026] The above description of the utility model is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0045] Currently, potash fertilizer sampling is mainly done manually. However, the large number of potash fertilizer ponds to be sampled results in a high sampling frequency, reducing work efficiency.

[0046] In view of this, this application provides an online automatic sampling concentration identification system for potash fertilizer, including a detection container 1, a liquid inlet module 2, a camera module 3, and a cleaning module 4. The liquid inlet module 2 includes two or more first liquid inlet pipes 21 and two or more sampling pumps 22. Each first liquid inlet pipe 21 is equipped with a sampling pump 22. The inlet of the first liquid inlet pipe 21 is used to connect to an external sampling pool 8, and the outlet of the first liquid inlet pipe 21 is connected to a main liquid inlet 11. The camera module 3 includes a camera 31, and the camera of the camera 31 is aimed at the detection container 1. The cleaning module 4 includes a main cleaning pipe 41, a main cleaning valve 42, and two or more cleaning branch pipes 43. The inlet of the main cleaning pipe 41 is used to connect to an external tap water 7, and the outlet of the main cleaning pipe 41 is equipped with a main cleaning valve 42. The inlets of the two or more cleaning branch pipes 43 are connected to the main cleaning pipe 41, and the outlet of each cleaning branch pipe 43 is connected to the cleaning port of a first liquid inlet pipe 21.

[0047] According to some embodiments of this application, please refer to Figures 1 to 5 This embodiment relates to an online automatic sampling concentration identification system for potash fertilizer, including a detection container 1, a liquid inlet module 2, a camera module 3, and a cleaning module 4. The detection container 1 has a main liquid inlet 11. The liquid inlet module 2 includes two or more first liquid inlet pipes 21 and two or more sampling pumps 22. Each first liquid inlet pipe 21 is equipped with a sampling pump 22. The inlet of the first liquid inlet pipe 21 is used to connect to an external sampling pool 8, and the outlet of the first liquid inlet pipe 21 is connected to the main liquid inlet 11. The camera module 3 includes a camera 31, the camera of which is aimed at the detection container 1; the cleaning module 4 includes a cleaning main pipe 41, a cleaning main valve 42, and two or more cleaning branch pipes 43. The inlet of the cleaning main pipe 41 is used to connect to the external tap water 7. The cleaning main valve 42 is installed at the outlet of the cleaning main pipe 41. The inlets of the two or more cleaning branch pipes 43 are connected to the cleaning main pipe 41. The outlet of each cleaning branch pipe 43 is connected to the cleaning port of a first liquid inlet pipe 21.

[0048] The detection container 1 can be made of a transparent material, such as a glass. The detection container 1 can be mounted on the camera 31 at the camera's shooting position using a mounting bracket, or it can be directly mounted on a table. In this embodiment, as shown... Figure 3 As shown, a main liquid inlet 11 is provided at the top of the detection container 1. In some embodiments, a main liquid inlet 11 may also be provided on one side of the detection container 1.

[0049] The external sampling cell 8 has multiple sampling cells, with one first inlet pipe 21 corresponding to one sampling cell. For example... Figure 1 and Figure 2 As shown, in this embodiment, the first liquid inlet pipe 21 is provided with 8 pipes, and the external sampling pool 8 has eight sampling pools.

[0050] Camera 31 is an existing camera 31, so it will not be described in detail. In some embodiments, the camera lens of camera 31 can rotate 360° to adjust the shooting angle.

[0051] The inlet of the main cleaning pipe 41 is connected to the external tap water 7, which is pressurized tap water, so there is no need to install a cleaning pump. Therefore, the two or more first inlet pipes 21 and two or more sampling pumps 22 can be cleaned directly by opening the main cleaning valve 42. The cleaned water can directly enter the detection container 1 and then be discharged through the detection container 1.

[0052] The above technical solution is equipped with two or more first inlet pipes 21 and corresponding sampling pumps 22, which allows potassium fertilizer samples from different sampling pools to be sequentially introduced into the detection container 1 for photographic detection. This automated control is more intelligent, reduces manual intervention, and improves sampling efficiency. Furthermore, a cleaning module 4 is provided to clean the inlet pipes and sampling pumps 22, preventing blockage of the inlet module 2 due to potassium fertilizer crystallization after long-term use.

[0053] like Figure 2 As shown, the cleaning module 4 also includes two or more cleaning branch valves 44. Each cleaning branch pipe 43 is equipped with a cleaning branch valve 44, which controls the corresponding cleaning branch pipe 43 to be open or closed.

[0054] Thus, by setting a corresponding cleaning branch valve 44 on each cleaning branch pipe 43, the cleaning branch pipe 43 can be cleaned selectively.

[0055] like Figure 2 and Figure 3 As shown, the detection container 1 is also provided with a main flushing port 12. The cleaning module 4 also includes a flushing pipe 45 and a flushing valve 46. The inlet of the flushing pipe 45 is connected to the main cleaning pipe 41, and the outlet of the flushing pipe 45 is connected to the main flushing port 12. The flushing valve 46 is installed on the flushing pipe 45 and controls the flushing pipe 45 to open or close.

[0056] A main flushing port 12 is provided at the top of the testing container 1.

[0057] Thus, by setting up the flushing pipe 45 and the flushing valve 46, the testing container 1 can be cleaned in a timely manner after one potash fertilizer sample test is completed, avoiding residual liquid from affecting the subsequent testing of the liquid to be tested. In addition, a final flush can be performed after all potash fertilizer samples to be tested have been tested, without affecting the testing of the next potash fertilizer sample.

[0058] like Figure 4 As shown, the bottom of the detection container 1 is provided with a main drain port 13. The online automatic sampling concentration identification system for potassium fertilizer also includes a drain module 5. The drain module 5 includes a drain pipe 51 and a drain valve 52. The inlet of the drain pipe 51 is connected to the main drain port 13, and the outlet of the drain pipe 51 is used to connect to the external return pool 9. The drain valve 52 is installed on the drain pipe 51 and controls the drain pipe 51 to open or close.

[0059] When a potassium fertilizer sample is introduced into the testing container 1, the drain valve 52 must be kept closed, and the drain pipe 51 must not be open. The drain valve 52 is opened only when the testing container 1 needs to be drained, allowing the drain pipe 51 to be open, and the drained liquid is collected uniformly through the external return tank 9.

[0060] Thus, by setting up the drainage module 5, the tested potassium fertilizer liquid can be drained, making it easier to put other potassium fertilizer samples to be tested into the testing container 1 for subsequent testing.

[0061] According to some embodiments of this application, optionally, the detection container 1 is also provided with a total overflow port, and the potash fertilizer online automatic sampling concentration identification system also includes an overflow pipe 6, the inlet of the overflow pipe 6 is connected to the total overflow port, and the outlet of the overflow pipe 6 is used to connect to the external return pool 9.

[0062] Optionally, a main overflow port is provided on the other side of the detection container 1.

[0063] Thus, by setting the overflow pipe 6, the liquid level can be automatically maintained to prevent liquid backflow.

[0064] like Figure 5 As shown, the liquid inlet module 2 also includes a liquid inlet container 23 and a second liquid inlet pipe. The liquid inlet container 23 has two or more first liquid inlets 231 and a first liquid outlet. The liquid outlet of each first liquid inlet pipe 21 is connected to a first liquid inlet 231, the first liquid outlet is connected to the liquid inlet of the second liquid inlet pipe, and the liquid outlet of the second liquid inlet pipe is connected to the main liquid inlet 11.

[0065] In this embodiment, the liquid inlet container 23 has eight first liquid inlets 231.

[0066] Thus, by setting the liquid inlet container 23 as a transition container, the number of liquid inlets on the detection container 1 can be reduced, without affecting the detection and extending the service life of the detection container 1.

[0067] like Figure 2 As shown, the camera module 3 also includes a light source 32, which is installed at a position relative to the camera 31, and the detection container 1 is located between the light source 32 and the camera 31.

[0068] Thus, by setting the light source 32, a backlight effect can be generated, thereby improving the accuracy of liquid turbidity identification and detection.

[0069] According to some embodiments of this application, optionally, the camera module 3 further includes a camera bracket, a vertical linear guide rail, and a horizontal linear guide rail. The vertical linear guide rail is mounted on the camera bracket, the horizontal linear guide rail is mounted on the vertical linear guide rail, and the camera 31 is mounted on the horizontal linear guide rail. The horizontal linear guide rail drives the camera 31 to move in the horizontal direction, and the vertical linear guide rail drives the camera 31 to move in the vertical direction.

[0070] The horizontal and vertical linear guides are existing linear guides, so they will not be described further.

[0071] In this way, by setting vertical and horizontal linear guide rails, three-dimensional spatial position adjustment can be achieved, thereby adapting to different liquid level heights and observation angles.

[0072] According to some embodiments of this application, optionally, an online automatic sampling concentration identification system for potash fertilizer further includes a control module, which is communicatively connected to the liquid inlet module 2, the camera module 3, and the cleaning module 4.

[0073] The control module can precisely control the opening and closing times and frequencies of various components according to a preset program. For example, after completing a sampling test, the control module can automatically control the opening of the cleaning branch valve 44 to clean the first inlet pipe 21; after cleaning, it can then control the opening of the drain valve 52 to discharge the cleaned liquid. Simultaneously, the control module can flexibly adjust the working state of the sampling pump 22 according to different testing needs, ensuring that the potassium fertilizer samples in the external sampling pool 8 enter the testing container 1 in a set order for photographing and testing. The control module can also control the photographing action of the camera 31. When a potassium fertilizer sample enters the testing container 1, the control module immediately triggers the camera 31 to take a picture, transmitting the image information of the potassium fertilizer sample to the background processing system. The background processing system can analyze the color, transparency, and other characteristics of the potassium fertilizer sample using image recognition technology, thereby quickly and accurately identifying the concentration of the potassium fertilizer. Furthermore, through learning and analyzing a large amount of image data, the control module can continuously optimize the recognition algorithm, improving the accuracy and reliability of concentration identification.

[0074] In some embodiments, the potash fertilizer online automatic sampling concentration identification system also includes an alarm module, which is communicatively connected to the control module. When the system malfunctions, such as a failure of the sampling pump 22, blockage of the cleaning module 4, or poor drainage, the alarm module will promptly issue an alarm signal to remind staff to perform inspection and maintenance. The alarm signal can be an audible alarm, a visual alarm, or an information alarm sent to the staff's mobile device via a network, ensuring that staff can promptly understand the system's operating status and guaranteeing the system's stable operation.

[0075] The working principle of the online automatic sampling concentration identification system for potash fertilizer is as follows:

[0076] First, the potassium fertilizer sample from one of the sampling pools in the external sampling pool 8 is pumped into the detection container 1. Once the potassium fertilizer sample enters the detection container 1, the sampling pump 22 stops operating, and the sample in the detection container 1 begins to settle. After the preset set settling time is reached, the camera 31 takes a picture to identify the concentration, opens the drain valve 52 to drain the liquid, and starts the cleaning module 4 to begin cleaning, until the preset time is reached. Afterward, sampling begins from the other sampling pools in the external sampling pool 8, repeating the above process until all sampling pools in the external sampling pool 8 have been sampled, completing this round of sampling.

[0077] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection for this utility model.
