Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 One embodiment provided by this utility model:

[0023] An online particle size analyzer with automatic sampling and cleaning functions includes a housing 1, a protective cover 11 rotatably connected to the surface of the housing 1, a controller 12 fixedly mounted on the surface of the housing 1, the controller 12 operating the entire online particle size analyzer, a detection chamber 2 fixedly connected inside the housing 1, lenses 21 fixedly connected to both ends of the detection chamber 2, a detector 22 fixedly mounted on the inner surface of the housing 1, a laser device 23 fixedly mounted on the inner surface of the housing 1, an air compressor 3 fixedly mounted inside the housing 1, an inlet pipe 31 fixedly connected to the input end of the air compressor 3, and an outlet pipe 32 fixedly connected to the output end of the air compressor 3. The end of the outlet pipe 32 away from the air compressor 3 is fixedly connected to the detection chamber 2, and a solenoid valve 33 is fixedly mounted on the surface of the outlet pipe 32. The solenoid valve 33 allows the detection gas to enter the detection chamber 2 through the outlet pipe 32, facilitating the entry of cleaning gas into the detection chamber 2 for cleaning. The detection chamber 2 is located away from the outlet pipe 3. An exhaust pipe 34 is fixedly connected to one side of the housing 2. A high-pressure pump 35 is fixedly connected to the inner surface of the housing 1. A high-pressure pipe 36 is fixedly connected to the output end of the high-pressure pump 35. A high-pressure nozzle 37 is fixedly connected to the surface of the high-pressure pipe 36. The high-pressure nozzle 37 is fixedly connected to the top of the detection chamber 2. A filter cover 38 is fixedly connected to the outer surface of the housing 1. A filter sponge 39 is inserted into the surface of the filter cover 38. This online particle size analyzer can input gas through the high-pressure pipe 36 and the high-pressure nozzle 37 to automatically clean the detection chamber and lens 21 of the detection chamber 2. The gas input by the high-pressure pump 35 is filtered through the filter cover 38 and the filter sponge 39, resulting in a better cleaning effect. The air compressor 3 can create a negative pressure zone in the airflow, so that the air compressor 3 delivers the detection gas to the gas delivery pipe 32 through the air inlet pipe 31, and then delivers the detection gas to the detection chamber of the detection chamber 2 through the gas delivery pipe 32, thus completing the automatic sampling of the gas.

[0024] Furthermore, the intake pipe 31 is located at the bottom of the protective cover 11, and the end of the exhaust pipe 34 away from the test box 2 is located at the bottom of the protective cover 11. The protective cover 11 protects the intake pipe 31 and the exhaust pipe 34 on the housing 1, thereby extending the service life of the intake pipe 31 and the exhaust pipe 34.

[0025] Furthermore, the inside of the detection box 2 is a detection chamber, with two sets of lenses 21 located on both sides of the detection chamber. The laser device 23 emits detection gas that passes through the two sets of lenses 21 and the detection chamber of the detection box 2. Three sets of detectors 22 are set up to detect scattered light from the front, sides, and rear respectively.

[0026] Furthermore, the air compressor 3 delivers the gas to be tested through the intake pipe 31 and the gas delivery pipe 32 to the detection chamber of the detection box 2. The detection box 2 discharges the gas from the inside of the casing 1 through the exhaust pipe 34, thereby realizing continuous detection of particulate matter on the gas.

[0027] Furthermore, a through hole is provided on the surface of the housing 1, and the output end of the exhaust pipe 34 is located inside the through hole of the housing 1, which allows the exhaust pipe 34 to absorb air from outside the housing 1 and output it to the high-pressure pipe 36. The high-pressure pump 35 outputs the gas through the high-pressure pipe 36 to the high-pressure nozzle 37. The high-pressure nozzle 37 outputs the gas to the detection chamber of the detection box 2. The gas output by the high-pressure nozzle 37 cleans the detection chamber of the detection box 2 and the two sets of lenses 21. The gas is then discharged through the exhaust pipe 34.

[0028] Furthermore, the filter cover 38 is fixed to the outside of the through hole of the housing 1, and multiple sets of filter holes are opened on the surface of the filter cover 38 for primary filtration of air to ensure the cleanliness of the clean gas.

[0029] Furthermore, a slot is provided on the top of the filter cover 38, and the filter sponge 39 is snapped into the slot of the filter cover 38. The filter sponge 39 is in contact with the through hole of the housing 1. The filter sponge 39 performs secondary filtration on the gas entering the output end of the high-pressure pump 35, thereby ensuring the cleanliness of the clean gas. A circular hole is provided on the bottom of the filter cover 38. The filter sponge 39 on the filter cover 38 can be directly pushed out using tools such as a rod, making it convenient to replace the filter sponge 39.

[0030] Working principle: The air inlet pipe 31 is connected to the gas detection area. The air compressor 3 creates a negative pressure zone in the gas detection area. The air compressor 3 delivers the gas to be detected to the detection chamber of the detection box 2 through the air inlet pipe 31 and the air delivery pipe 32. No manual gas sampling is required, realizing automatic gas sampling. After the gas detection is completed, the high-pressure pump 35 draws in the gas outside the casing 1 and filters it through the filter cover 38 and the filter sponge 39. The high-pressure pump 35 outputs the clean gas to the detection chamber of the detection box 2 through the high-pressure pipe 36 and the high-pressure nozzle 37. The gas carries away the particles on the detection chamber of the detection box 2 and the two sets of lenses 21, and is discharged from the inside of the casing 1 through the exhaust pipe 34. This completes the automatic cleaning of the detection chamber of the detection box 2 and the two sets of lenses 21, reducing the long maintenance time of the online particle size analyzer and thus improving the testing efficiency of the online particle size analyzer.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
