Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a novel insoluble particle detector. Background Art

[0002] The insoluble particle tester is an instrument used to measure the amount of non-soluble substances in liquids. It is widely used in various industries and fields to provide key data for scientific research and production. Its function is to determine the size, shape and quantity of insoluble particles in the sample by analyzing and testing the sample, so as to further study the characteristics and applications of the sample. The working principle of the insoluble particle tester is to quantitatively analyze the particles in the translucent liquid sample through optical principles and image analysis techniques. During the specific test, the sample to be tested is placed in the container of the tester, and then the sample is irradiated with a light source device. Under the light, the particles in the sample will scatter light to form a specific diffraction light signal. After being received by the receiving head distributed laterally with the light source device, it is output to the software analysis system of the tester. The system uses image analysis technology to capture and process the information of these scattered lights, so as to analyze and obtain accurate particle data. In this way, by analyzing the parameters such as the size, distribution and shape of the particles in the sample, researchers can better understand the quality, purity and stability of liquid materials, and provide a basis for the design and development of materials.

[0003] Although the existing liquid insoluble particle tester meets the detection needs to a certain extent, it is limited by the structure and still has the following technical problems to be solved. First, it can only detect the liquid samples that the tester has fixedly placed in the container of the tester. When the tester needs to sample the liquid produced by the assembly line, the tester needs to manually place part of the liquid output by the assembly line into the container of the tester for testing, and after the test is completed, the container needs to be manually discharged. The above operation mode will bring inconvenience to the tester, and is not conducive to improving the detection efficiency, and increases the detection cost. Secondly, the sample is tested in a static state during the test, which will bring a problem that the insoluble particles in the liquid have a relatively light specific gravity and float on the liquid, or have a relatively large specific gravity and sink to the bottom of the liquid. It is impossible to effectively ensure that the light source emitted by the light source equipment passes through the particles in the liquid and is received by the receiving head, which will have an adverse effect on the detection effect of the liquid. In summary, it is particularly necessary to provide an insoluble particle detector that can automatically detect the liquid output from the assembly line at certain intervals and can stir and mix the sample entering the container to achieve better detection effect. Utility Model Content

[0004] In order to overcome the drawbacks of the existing insoluble particle detectors as described in the background due to structural limitations, the utility model provides an insoluble particle detector body based on the detection of liquid production equipment in the assembly line. In application, under the joint action of relevant mechanisms, part of the liquid can be automatically input into the container for detection at regular intervals, and the liquid can be automatically output after the detection, and the liquid in the container can be stirred, thereby ensuring the accuracy of the detection data as much as possible (the amount of detected data is larger and more diverse), and when the amount of insoluble particles in the detected liquid is too much, it can automatically sound to remind the relevant detection personnel, thereby preventing the excessive amount of insoluble particles and the detection personnel from failing to observe the relevant data in time for processing, resulting in unqualified quality of the liquid output from the assembly line.

A bearing seat 33 is installed in the inner middle of the rear end of the container, and the front end of the stirring shaft 31 and the rear end of the rotating shaft are welded together, and the rear end of the stirring shaft 31 is sealed and tightly sleeved in the inner ring of the bearing of the bearing seat 33; the receiving control circuit is equipped with a photoelectric triode Q1, and there is an opening on the right side of the upper end of the container 103, and the photoelectric triode Q1 is sealed and glued in the opening. The power module W1, the time control switch W2 and the receiving control circuit 2 are installed on the circuit board in the electric control box 4 of the insoluble particle detector body.

[0015] Figure 1 , 2As shown in FIG. 1 , the solenoid valves DC1 and DC2 are normally closed valve core solenoid valves with a power of 2 W. The light receiving surface of the phototransistor Q1 is located on the right side of the container. The receiving control circuit includes resistors R1, R2, R3 and an adjustable resistor RP1, a buzzer B1, a transistor Q2, and a relay K1 connected via circuit board wiring, and is connected to the phototransistor Q1 via a wire. The collector of the phototransistor Q1 is connected to one end of the first resistor R1, the emitter of the phototransistor Q1 is connected to one end of the adjustable resistor RP1, the other end of the adjustable resistor RP1 is connected to one end of the second resistor R3 and one end of the third resistor R2, the other end of the second resistor R3 is connected to the base of the transistor Q2, the other end of the third resistor R2 is connected to the emitter of the transistor Q2 and the negative power input end of the buzzer B1, the collector of the transistor Q2 is connected to the negative power input end of the relay K1, the normally closed contact end of the relay K1 is connected to the positive power input end of the buzzer B1, and the positive power input end and the control power input end of the relay K1 are connected to the other end of the first resistor R1. The power input terminals 1 and 2 of the power module W1, the power input terminals 1 and 2 of the time switch W2 and the two poles of the AC 220V power supply are connected via wires respectively, the power output terminals 3 and 4 of the power module W1 and the power input terminal of the receiving control circuit, the positive power input terminal of the relay K1 and the emitter of the transistor Q1 are connected via wires respectively, and the power output terminals 3 and 4 of the time switch W2 and the two solenoid valves DC1 and DC2, the motor reduction device M and the power input terminal of the insoluble particle detector body are connected via wires.

[0016] Figure 1 , 2As shown, after the AC power enters the power input terminal of the power module W1, the power module W1 is powered on and works, and the power module W1 outputs a stable DC 12V power supply and enters the power input terminal of the receiving control circuit. Specifically, after the insoluble particle detector body 1 is powered on and works, the tester places the sample to be tested in the container 103 of the tester, and the light source device 101 irradiates the sample. Under the light, the particles in the sample will scatter light, forming a specific diffraction light signal, which is received by the receiving head 102 distributed laterally with the light source device 101 and output to the software analysis system supporting the tester body. The system captures and processes the information of these scattered lights through image analysis technology, so as to analyze and obtain accurate particle data. In this way, by analyzing the parameters such as the size, distribution and shape of the particles in the sample, researchers can better understand the quality, purity and stability of the liquid material, and provide a basis for the design and development of the material (the above is an existing mature technology, and this application will not repeat it, and will not protect the insoluble particle detector body 1 itself). After the new time-controlled switch W2 is powered on, its 3rd and 4th pins will output a certain amount of power at certain intervals (the time is adjustable, for example, power is output for one minute at one minute intervals) to enter the power input end of the insoluble particle detector body 1 and the solenoid valves DC1, DC2 and the motor reduction device M. After the insoluble particle detector body 1 is powered on, it can perform real-time detection of transparent liquid samples entering the container (non-transparent structure). After the solenoid valves DC1 and DC2 are powered on, the valve core opens, and the liquid output from the liquid pipeline enters the box body 101 through the solenoid valve DC1 with the valve core opened, and then flows out through the solenoid valve DC2 with the valve core opened and flows back into the liquid pipeline (flowing out to the liquid finished product box in the production area or the next production process). After the motor reduction device M is powered on, its rotating shaft drives the stirring shaft and blades to rotate (mixing the upper and lower layers of the liquid entering the container). In this way, through the above, the insoluble particle detector body 1 can be used in conjunction with the assembly line liquid production equipment for detection. In application, with the joint action of the time-controlled switch and the solenoid valve, part of the liquid can be automatically input into the container for detection at regular intervals. After the detection, the liquid can be automatically output (the amount of detected data is larger and more diverse), and the liquid in the container can be stirred, thereby ensuring the accuracy of the detection data as much as possible.

[0017] Figure 1 , 2As shown, the light emitted by the electric light source device 101 of the insoluble particle detector body 1 will cause light to be transmitted in the transparent liquid. The light is irradiated on the light receiving surface of the phototransistor Q1. When the amount of insoluble particles in the liquid is small, the liquid has relatively high light transmittance. The light intensity of the light source irradiating on the light receiving surface of the phototransistor Q1 is relatively large, and the internal resistance of the phototransistor Q1 is relatively small. The 12V power supply is reduced by the resistor R1 and the current is limited, and the collector and emitter of the phototransistor Q1 are output, and then the adjustable resistor RP1 and the resistor R2 are divided, and the resistor R3 reduces the voltage and limits the current to enter the base of the transistor Q2, which is higher than 0.7V. The transistor Q2 is turned on and the collector outputs a low level and enters the negative power input terminal of the relay K1. The relay K1 is energized to attract its control power input terminal and the normally closed contact terminal are open, then the buzzer B1 will not be energized to sound, indicating that the amount of insoluble particles in the liquid has not exceeded the threshold; when the amount of insoluble particles in the liquid is When the amount of insoluble particles in the liquid exceeds the threshold, the light transmittance of the liquid is relatively low, and the light intensity of the light source irradiating on the light-receiving surface of the phototransistor Q1 is relatively low. The internal resistance of the phototransistor Q1 is relatively large. The 12V power supply is output by the resistor R1 after the voltage reduction and current limiting, the collector and emitter of the phototransistor Q1, and then the adjustable resistor RP1 and the resistor R2 divide the voltage. The resistor R3 reduces the voltage and limits the current to enter the base of the transistor Q2 below 0.7V. The collector of the transistor Q2 is cut off and no longer outputs a low level to enter the negative power supply input terminal of the relay K1. When the relay K1 loses power, it no longer attracts its control power input terminal and the normally closed contact terminal to close. Then the buzzer B1 will be energized and sound, indicating that the amount of insoluble particles in the liquid exceeds the threshold. The inspection personnel can conduct inspections in time to prevent the excessive amount of insoluble particles and the inspection personnel from not observing the relevant data in time for processing, resulting in unqualified liquid quality output from the assembly line, thereby ensuring production quality as much as possible.

The larger the adjustable resistor RP1 is adjusted by the tester, the greater the partial pressure is, and the amount of insoluble particles in the liquid is relatively small, the transistor Q1 will be turned on, that is, the threshold value of the insoluble particle amount of the new type is set to be relatively small; the smaller the adjustable resistor RP1 is adjusted by the tester, the smaller the partial pressure is, and the liquid When the amount of insoluble particles in the water is relatively large, the transistor Q1 will be turned on, that is, the threshold value of the amount of insoluble particles in the present invention is set appropriately); the photoelectric transistor Q1 model is 3DU5C; the motor stirring device M is a 50W coaxial motor gear reducer finished product; the solenoid valves DC1 and DC2 are normally closed valve core AC solenoid valves; the buzzer B is a model FM12V active continuous sound buzzer alarm finished product; the power supply module W1 is an AC 220V to DC 12V power supply module finished product; the time control switch W2 is a time timer model KG316T, which has two power input terminals, two power output terminals, and seven setting buttons.
