Description

Technical Field

[0001] The utility model belongs to the technical field of online particle counting systems, in particular to a sample homogenizing and stirring device for an online particle counting system. Background Art

[0002] The particle counting system is an instrument used to test the particle size and distribution of oil particles. It can monitor the cleanliness of oil in real time in the oil filtration and purification equipment, optimize the filtration process, ensure the quality of oil, and prevent equipment failure. It uses the principle of light scattering or resistance sensing to quickly and accurately count and size the solid particles in the oil. When the oil flows through the detection area, the particles will scatter light or change resistance. The instrument captures these signals and analyzes and processes them to obtain the number, size and distribution of particles. When the oil sample is monitored by the online particle counting system, in order to avoid the precipitation of particles in the oil and cause inaccurate measurement results, it is usually necessary to stir the oil sample evenly before monitoring it through the online particle counting system. Mixing the oil sample by a mixing device can improve the monitoring and processing efficiency and reduce the labor intensity of the staff, but it still has the following disadvantages in actual use:

[0003] Most homogenous mixing devices first mix the oil sample evenly and then pour the mixed oil sample into the online particle counting system. The operation is relatively cumbersome and greatly reduces the oil monitoring speed when monitoring multiple oil samples.

[0004] When the oil sample is mixed by the homogenizing stirring device, the contact between the stirring blade and the oil will cause the stirring blade and impurities to rub against each other, resulting in the temperature of the oil sample to rise, which may affect the properties of the oil sample and reduce the accuracy of the monitoring results of the online particle counting system. Utility Model Content

[0005] The utility model aims to provide a sample homogenizing and stirring device for an online particle counting system. By means of a homogenizing and stirring box, an air pump and a top cover, the utility model solves the problem that when an oil sample is homogenized and stirred, it needs to be mixed in a stirring device before being poured into an online particle counting system, which is time-consuming and labor-intensive and reduces the monitoring speed. When the device stirs the oil sample, the friction between the stirring blade and the particles in the oil will cause the oil sample to heat up, which may affect the properties of the oil sample and reduce the accuracy of the monitoring result.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a sample homogenizing and stirring device for an online particle counting system, comprising a homogenizing and stirring box, an air pump and a top cover, wherein the top cover is fixedly connected to the top of the homogenizing and stirring box, a limit plate is inserted into the homogenizing and stirring box, a plurality of ventilation pipes are welded through the bottom of the limit plate, an air pump is fixedly connected to the top of the top cover, and a filter assembly is arranged on one side of the air pump;

[0008] The oil sample to be monitored is poured into the mixing box, and air is pumped into the oil sample passing through the mixing box by an air pump. The rapid flow of air in the oil sample makes the particles in the oil sample evenly distributed in the oil sample. The operation is simple and convenient, and there is no need to use a stirring blade to stir the oil sample, thereby avoiding the temperature rise of the oil sample and ensuring the accuracy of the monitoring result. The air pumped into the oil sample can be filtered through the filter component to avoid the dust in the air from polluting the oil sample and ensuring the accuracy of the monitoring result. The air pump drives the airflow to mix the oil passing through the mixing box in real time, so that the online particle counting system can monitor the particle content of the oil in real time, ensure the accurate control of the filtering performance of the filtering device, ensure the quality of the oil, and do not need to be monitored by the counting system after mixing, thereby improving the monitoring speed.

[0009] Furthermore, a first feed pipe is welded through the bottom of the outer circumference of the mixing box, a second feed pipe is welded through the outer circumference of the mixing box, and a mounting connecting plate is welded and fixed to the outer circumference of the first feed pipe and the second feed pipe relative to the other end of the mixing box, and the second feed pipe is located between the limiting plate and the first feed pipe;

[0010] Multiple oil samples continuously enter the mixing box through the second feeding pipe and are mixed in the mixing box. The treated oil samples are quickly transported to the online particle counting system through the first feeding pipe for monitoring. The thickness of the first feeding pipe can be adjusted, and a slow flow plate can be set in the mixing box to adjust the speed of the oil passing through the mixing box, so as to ensure that the oil is fully mixed before entering the online particle counting system for monitoring.

[0011] Furthermore, an air inlet pipe is inserted through the bottom of the air pump, a connecting pipe is inserted through the outer peripheral surface of the air pump, the other end of the connecting pipe is inserted through the top of the outer peripheral surface of the welding filter assembly, the filter assembly is located outside the mixing box, and the air inlet pipe is inserted through the top of the top cover;

[0012] The air pump can be used to pump air into the mixing box. The flow of air in the oil sample causes the oil to churn continuously, so that the impurity particles in the oil are evenly mixed with the oil, thereby ensuring the accuracy of the monitoring results. By pumping air into the oil through the air pump, the use of stirring blades to stir the oil, which may cause the oil to heat up, ensures that the physical and chemical properties of the oil remain unchanged, and further ensures the accuracy of the monitoring results.

[0013] Furthermore, a bottom cover is fixedly connected to the bottom of the filter assembly, an air extraction pipe is welded through the bottom of the bottom cover, an air filter element is screwed and fixed to the top of the bottom cover, the air filter element is plugged into the inner side of the filter assembly, and the air extraction pipe is connected to the inside of the air filter element;

[0014] When the air pump is pumping air, the air is first filtered through the air filter element, and then enters the oil to drive the oil to churn, avoiding dust in the air from contaminating the oil and ensuring the accuracy of the monitoring results.

[0015] Furthermore, a guide frame is welded and fixed on the top of the limiting plate, and the top of the guide frame is welded and fixed to the bottom of the top cover, the air inlet pipe is inserted through the inner side of the guide frame, a vent hole is opened through the top edge of the limiting plate, and an exhaust pipe is welded through the top of the top cover, the vent hole and the exhaust pipe are both located outside the guide frame, a plurality of the vent pipes are connected through the guide frame, and an air outlet is opened through the outer peripheral surface of each vent pipe;

[0016] The air outlet can allow air to be pumped into various positions in the mixing box to mix the oil at different positions to ensure uniform mixing. The air pumped into the mixing box can be discharged through the vent and the exhaust pipe when it separates from the oil, thereby preventing the oil from entering the mixing box due to excessive air pressure, and preventing the unevenly mixed oil from being quickly discharged through the first feed pipe due to excessive air pressure.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that most homogenizing and stirring devices first evenly stir the oil sample and then pour the stirred oil sample into the online particle counting system, which is cumbersome to operate and greatly reduces the monitoring speed of the oil when monitoring multiple oil samples. When the oil enters the homogenizing and stirring box, the air pump pumps clean air into the oil passing through the homogenizing and stirring box, and the flow of air drives the oil to churn, so that the impurity particles in the oil are evenly mixed with the oil, thereby ensuring the accuracy of the monitoring result, and being able to evenly mix the oil in real time, so that the online particle counting system can monitor the particle content of the oil in real time, thereby ensuring the accurate control of the filtering performance of the filtering device and the quality of the oil, and there is no need to monitor through the counting system after mixing, thereby improving the monitoring speed.

[0019] The utility model provides an air pump and a top cover to solve the problem that when the oil sample is mixed by the homogenizing stirring device, the contact between the stirring blade and the oil will cause the stirring blade and impurities to rub, resulting in the temperature rise of the oil sample, which may affect the properties of the oil sample and reduce the accuracy of the monitoring result of the online particle counting system. The air in the air environment is continuously pumped into the oil by the air pump to make the oil churn, and the impurity particles in the oil are further mixed with the oil evenly, thus avoiding the use of the stirring blade to stir the oil which may cause the temperature rise of the oil, ensuring that the physical and chemical properties of the oil remain unchanged, and further ensuring the accuracy of the monitoring result.

[0028] After connecting the mixing box 1 and the water inlet of the online particle counting system, pour the oil sample into the mixing box 1, and start the mixing device. When the oil passes through the mixing box 1, the air pump 2 evacuates the external environment, and the air purified by the air filter 205 enters the mixing box 1, and is diverted and pressed into the oil through multiple ventilation pipes 305. The air moves upward in the oil and drives the oil to churn, so that the impurity particles in the oil are evenly mixed with the oil, and then the evenly mixed oil is poured into the online particle counting system through the first feeding pipe 101 for monitoring and processing.

[0030] The first feeding pipe 101 is connected to the online particle monitoring system by bolts passing through and screwed on the mounting connecting plate 103, and the second feeding pipe 102 is connected to the oil processing device, so that the processed oil sample enters the mixing box 1 through the second feeding pipe 102, flows slowly through the mixing box 1, and the oil is churned by the flow of air to mix the oil sample evenly, and after being evenly mixed, the oil is moved to the online particle counting system through the first feeding pipe 101 for monitoring and processing.

[0032] When the oil sample enters the mixing box 1, the air pump 2 draws air from the outside through the suction pipe 204, and the air is filtered through the filter component 202 and the air filter element 205, so that the clean air enters the mixing box 1 through the connecting pipe 201 and the air inlet pipe 206. The flow of air in the oil sample causes the oil to churn continuously, so that the impurity particles in the oil are evenly mixed with the oil.

[0033] Among them Figure 1 , 4As shown, a guide frame 302 is welded and fixed on the top of the limiting plate 303, and the top of the guide frame 302 is welded and fixed to the bottom of the top cover 3. The air inlet pipe 206 penetrates and is plugged into the inner side of the guide frame 302. A vent hole 304 is penetrated and opened on the top edge of the limiting plate 303. An exhaust pipe 301 is welded and penetrated on the top of the top cover 3. The vent hole 304 and the exhaust pipe 301 are both located outside the guide frame 302.

The oil sample is poured into the mixing box 1 through the second feeding pipe 102 as needed, and the oil is slow-flowed through the mixing box 1. When the oil flows, the air pump 2 draws air from the outside through the suction pipe 204, and the air is filtered through the filter assembly 202 and the air filter element 205, so that the clean air is vented. The air enters the mixing box 1 through the connecting pipe 201 and the air inlet pipe 206, and is guided by the guide frame 302, so that the air is pumped to different positions in the mixing box 1 through multiple air outlets 306 of multiple ventilation pipes 305.
