Description

Technical Field

[0001] The invention relates to the technical field of turbidity meters, in particular to a turbidity meter. Background Art

[0002] Turbidimeters are used in water production and treatment plants before and after filtration, during sedimentation and at the outlet of the water plant, as well as municipal pipe network water, industrial process water quality testing, circulating cooling water, activated carbon filter effluent, membrane filtration effluent, and other occasions where there are certain requirements for turbidity in the water and testing is required.

[0003] However, the existing turbidity meter has suspended objects (such as leaves, anaerobic sludge accumulated in pipes, foam plastic particles, etc.) in the water sample to be tested. Such suspended solids will float on the surface of the water sample to be tested and cannot flow out of the entire measurement process through the overflow port. Once a long time has passed, the suspended matter will block the incident light source and the water sample, causing the turbidity meter measurement value to be lower than the actual turbidity of the water sample, and the measurement effect cannot be guaranteed. In addition, the existing turbidity meter has substances with good sedimentation performance (such as sand, small stones, aquatic organisms, etc.) in the water sample to be tested. Such substances will gradually accumulate in the water inlet diversion trough, which will eventually cause blockage and overflow of the water sample as the running time increases, thereby damaging the electrical part of the turbidity meter. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the present invention provides a turbidity meter, which overcomes the deficiencies of the prior art and has a simple structural design. It effectively solves the problem that suspended objects (such as leaves, anaerobic sludge accumulated in pipes, foam plastic particles, etc.) appear in the water sample to be tested by the existing turbidity meter. Such suspended solids will float on the surface of the water sample to be tested and cannot flow out of the entire measurement process through the overflow port. Once a long time has passed, the suspended matter will be blocked between the incident light source and the water sample, resulting in the turbidity meter measuring value being lower than the actual turbidity of the water sample, and the measurement effect cannot be guaranteed. In addition, substances with good sedimentation performance (such as sand, small stones, aquatic organisms, etc.) appear in the water sample to be tested by the existing turbidity meter. Such substances will gradually accumulate in the water inlet diversion groove, which will eventually cause blockage and overflow of the water sample as the running time increases, thereby damaging the electrical part of the turbidity meter.

[0029] Among them, the interior of the solenoid valve 9 is sequentially provided with a wiring port 901, a drive shaft 902, a rotating rod 903, a fixed rod 904 and a valve plate 905. The valve plate 905 is movably connected to the inner side of the pipeline 15. The middle part of the valve plate 905 is fixedly connected to the rotating rod 903, and the two sides of the rotating rod 903 are fixedly connected to the fixed rods 904.

[0030] In this embodiment, through this design, when the rotating rod 903 is driven, it can rotate with the valve plate 905 on the inner side of the pipe 15, thereby opening and closing the valve inside the pipe 15, and the fixed rods 904 on both sides of the rotating rod 903 play a role of firmly supporting the valve plate 905, thereby increasing the firmness and service life of the valve plate.

[0031] The lower end of the rotating rod 903 is movably connected to the driving shaft 902 , and the lower end of the driving shaft 902 is fixedly connected to the wiring port 901 , so that the driving shaft 902 and the rotating rod 903 are in a matching relationship.

[0032] In this embodiment, through this design, when the automatic switch 1101 is closed, the wiring port 901 will be energized, causing the drive shaft 902 to rotate, and the drive shaft 902 and the rotating rod 903 are in a matching relationship, so that the drive shaft 902 can better drive the rotating rod 903, and is less likely to have jamming and delays, thereby increasing the timeliness of the command.

[0033] The inner side of the measuring light source 3 is fixedly connected with an incandescent lamp 4 , the lower end of the measuring light source 3 is fixedly connected with a photodetector 5 , and the incandescent lamp 4 and the photodetector 5 are arranged at 90°.

[0034] In this embodiment, through this design, the incandescent lamp 4 will emit light into the water sample, and the photoelectric detector 5 immersed in the water sample detects the scattered light at 90 degrees to the incident light to achieve turbidity measurement.

The automatic switch 1101 is circuit-connected to the solenoid valve 9. The left side of the automatic switch 1101 is fixedly connected to the power interface 1102, and the upper end of the power interface 1102 is fixedly connected to the time display meter 1103.

[0036] In this embodiment, through this design, the time display table 1103 can perform timing control on the automatic switch 1101, and the automatic switch 1101 and the solenoid valve 9 are in a circuit connection relationship, so that the opening and closing of the automatic switch 1101 can drive the driving shaft 902 in the solenoid valve 9, and the solenoid valve 9 controls the discharge and closing of the pipeline 15, thereby realizing the timed emptying of the water sample and debris in the measuring chamber 1.

[0039] The inner side of the air defense valve 13 is connected with an electric ball valve 14 , and the air defense valve 13 and the water inlet guide groove 2 are arranged in parallel.

[0040] In this embodiment, through this design, when materials with good sedimentation performance gradually accumulate in the water inlet diversion groove, the water in the air defense valve 13 can flush the sediment on the water inlet diversion groove 2 through the control of the electric ball valve 14, so that the water inlet diversion groove 2 will not cause blockage as the operating time increases, thereby avoiding overflow of the sampling port 8 and damaging the electrical part of the device.

[0041] The sample inlet 8 is perpendicular to the lower end of the water inlet guide groove 2, and the sample inlet 8 and the air defense valve 13 are arranged at 90 degrees.

Through the air defense valve 13 and the electric ball valve 14, when the substances with good sedimentation performance gradually accumulate in the water inlet diversion groove 2, the water in the air defense valve 13 can be controlled by the electric ball valve 14 to flush the sediment on the water inlet diversion groove 2, so that the water inlet diversion groove 2 will not be blocked with the increase of running time, avoiding overflow of the sample inlet 8 and damaging the electrical part of the device, and can cooperate with the vent 6 and the solenoid valve 9 to perform functions such as flushing, rinsing and emptying of the inside of the turbidity meter, thereby extending the maintenance period of the turbidity meter and facilitating practical use.
