[0039] Example 1

[0040] like Figures 1 to 8 As shown, this utility model provides a technical solution:

[0041] An automatic measuring device for sedimentation ratio of a mixed liquid includes, but is not limited to, an equipment housing 1, a piping system 2, a measuring cylinder 3, and a measuring component 4. The equipment housing 1 is provided with a first partition 11, which divides the equipment housing 1 into a first cavity 12 and a second cavity 13. The measuring component 4 and the measuring cylinder 3 are disposed in the first cavity 12, and the piping system 2 is disposed in the second cavity 13. The piping system 2 and the measuring cylinder 3 are connected by a pipe.

[0042] Based on the above structure, when it is necessary to measure the stratification of the mixture, the mixture is transported to the measuring cylinder 3 through the pipeline system 2, so that the mixture is stratified in the measuring cylinder 3. Then, the measuring component 4 is used to detect the stratified measuring cylinder 3, automatically measuring the location of the stratification interface. The volume of the stratification can be calculated from the size of the measuring cylinder 3. This solution uses the measuring component 4 for automated measurement, which is more accurate and has a lower error rate compared with manual measurement.

[0043] As an example, a second partition 14 is provided in the second cavity 13, which divides the second cavity 13 into upper and lower cavities. The pipeline system 2 is respectively provided in the upper and lower cavities. A liquid pump 21 is provided in the pipeline system 2, and the inlet pump is provided on the second partition 14. The inlet end of the pipeline system 2 is provided in the lower cavity, and the outlet end of the pipeline system 2 is provided in the upper cavity.

[0044] Based on the above structure, the second partition 14 is provided to provide structural support for the liquid inlet pump, so that the liquid inlet pump can be stably fixed inside the equipment box 1. On the other hand, it separates the liquid inlet end and the liquid storage end of the pipeline system 2, so as to avoid mutual interference between the liquid inlet end and the liquid storage end of the pipeline system 2 in the event of an accident.

[0045] As an example, the piping system 2 may specifically include a cleaning fluid inlet pipe 22, a mixed liquid inlet pipe 23, a main delivery pipe 24, a cleaning fluid outlet pipe 25, and a mixed liquid outlet pipe 26; the cleaning fluid inlet pipe 22 and the mixed liquid inlet pipe 23 are connected to the bottom of the main delivery pipe 24 through a tee pipe, the cleaning fluid outlet pipe 25 and the mixed liquid outlet pipe 26 are connected to the top of the main delivery pipe 24, and the inlet pump is installed on the main delivery pipe 24.

[0046] Based on the above structure, under the action of the liquid inlet pump, cleaning liquid can be filled into the measuring cylinder 3 along the cleaning liquid inlet pipe 22, the main delivery pipe 24 and the cleaning liquid outlet pipe 25 to clean the measuring cylinder 3, so as to avoid the impurities remaining in the measuring cylinder 3 from affecting the next layer measurement; at the same time, mixed liquid can be filled into the measuring cylinder 3 along the mixed liquid inlet pipe 23, the main delivery pipe 24 and the mixed liquid outlet pipe 26 for layer measurement; the two pipelines adopt the same pump body 211 structure and the main delivery pipe 24, which can reduce the overall complexity and reduce the overall manufacturing cost.

[0047] As an example, solenoid valves 27 are installed on the cleaning fluid inlet pipe 22, the mixed liquid inlet pipe 23, the cleaning fluid outlet pipe 25, and the mixed liquid outlet pipe 26.

[0048] Based on the above structure, the solenoid valve 27 can be set to automatically open or close the required pipelines, thereby achieving automated operation.

[0049] As an example, both the cleaning fluid outlet pipe 25 and the mixed fluid outlet pipe 26 pass through the first partition 11 and are connected to the measuring cylinder 3; the end of the cleaning fluid outlet pipe 25 is connected to the measuring cylinder 3 through the rinsing pipe 28.

[0050] The flushing pipe 28 includes a flushing ring pipe 281, a bent pipe 282, and an expansion joint 283; the expansion joint 283 is connected to the end of the cleaning fluid outlet pipe 25, the end of the expansion joint 283 away from the cleaning fluid outlet pipe 25 is connected to the bent pipe 282, and the bent pipe 282 is connected to the end of the flushing ring pipe 281.

[0051] The flushing ring pipe 281 includes a straight pipe section and a ring pipe section. One end of the straight pipe section is connected to the bent pipe 282, and the other end is connected to the ring pipe section. The ring pipe section is provided with flushing holes 284 evenly arranged. The liquid outlet direction of the flushing holes 284 is set at a 45° angle to the wall surface of the measuring cylinder 3.

[0052] The size of the annular section is matched with the size of the opening end of the measuring cylinder 3, and the connection point between the cleaning fluid outlet pipe 25 and the measuring cylinder 3 is located at the center of the annular section.

[0053] Based on the above structure, when the equipment enters the rinsing process, the rinsing water pressurized by the liquid pump 21 can be pressurized again through the expansion joint 283, thereby increasing the rinsing pressure and improving the rinsing efficiency. In addition, the rinsing ring pipe 281 can change the rinsing water flow direction. Through the 45-degree inclined small hole on the rinsing ring pipe 281, the rinsing water is made to rinsing in a spiral direction along the measuring cylinder 3 at a 45-degree angle, increasing the rinsing area and improving the rinsing efficiency.

[0054] As an example, the measuring cylinder 3 may include a cylinder body 31, an overflow pipe 32, and a vent pipe 33. The cylinder body 31 is provided with a scale, the overflow pipe 32 is located at the highest point of the scale on the measuring cylinder 3, and the vent pipe 33 is located at the bottom of the measuring cylinder 3.

[0055] Based on the above structure, in the mixed liquid sampling and detection stage, the overflow pipe 32 can ensure that the sampled liquid is discharged from the measuring cylinder 3 after reaching the specified volume, avoiding errors in the results caused by excessive mixed liquid; in the sampling pump rinsing process, the rinsing water along with the rinsing dirt is discharged through the vent pipe 33.

[0056] As an example, the liquid pump 21 may include a pump body 211, an outlet check valve 212, and an inlet check valve 213; the inlet check valve 213 and the outlet check valve 212 are respectively disposed on the inlet end and the outlet end of the pump body 211.

[0057] Based on the above structure, by setting an outlet check valve 212 and an inlet check valve 213 at both ends of the pump body 211, liquid backflow can be avoided, and accurate metering of the mixture can be achieved.

[0058] As an example, the measuring component 4 may include a power unit and a photoelectric sensor 41; the photoelectric sensor 41 is disposed close to the cylinder body 31 of the measuring cylinder 3; under the action of the power unit, the photoelectric sensor 41 can move along the length direction of the measuring cylinder 3.

[0059] The power component can be a linear module of stepper motor 42; the linear module of stepper motor 42 includes stepper motor 42, lead screw module 43 and mounting base 44; the movable end of the lead screw module is connected to the mounting base 44, the mounting base 44 is connected to the photoelectric sensor 41, and the stepper motor 42 is fixedly installed on the inner side wall of the equipment housing 1.

[0060] Based on the above structure, when performing the detection function, the stepper motor 42 linear module drives the photoelectric sensor 41 to move upward from the 0 mark position of the measuring cylinder 3. The height of the layered liquid surface (the distance the photoelectric sensor 41 moves upward) is detected by the photoelectric sensor 41 through the difference in signals of the upper and lower liquids after the layering, thereby obtaining the sedimentation ratio data (the height of the layered liquid can be converted into sedimentation ratio data). The stepper motor 42 achieves precise control by being paired with the integrated controller 5, driving the lead screw module 43 to move up and down, thereby driving the photoelectric sensor 41 to move up and down along the measuring cylinder 3 to detect the layered liquid surface after the mixture has been left to stand.

[0061] As an example, an integrated controller 5 can also be installed on the equipment housing 1; the integrated controller 5 is connected to the linear module of stepper motor 42, photoelectric sensor 41, solenoid valve 27 and liquid pump 21 respectively. The integrated controller 5 realizes the switching control of the linear module of stepper motor 42, photoelectric sensor 41, solenoid valve 27 and liquid pump 21.

[0062] In this scheme, when the equipment enters the detection state, the feed pipe solenoid valve 27 opens, and the mixed liquid enters the liquid pump 21 through the mixed liquid feed pipe. After being pressurized by the liquid pump 21, it is injected into the measuring cylinder 3 through the mixed liquid discharge pipe. When the predetermined capacity is reached, the liquid pump 21 and the solenoid valve 27 close, thus completing the sampling process. After the data measurement is completed, the solenoid valve 27 opens, and the rinsing water enters the liquid pump 21 through the water inlet pipe. After being pressurized by the liquid pump 21, and further pressurized by the specially designed reducing pipe and annular spray pipe of the rinsing pipe 28, and changing the water flow direction, the rinsing water washes away the dirt on the cylinder wall of the measuring cylinder 3, thus completing one rinsing process.

[0063] This design also enables the transmission of mixed liquor sedimentation ratio data to the central control room via an integrated controller 5. This design allows for both remote control of sampling and detection from the central control room and the setting of a sampling and detection cycle, enabling 24-hour periodic sampling and detection.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
