Description

Technical Field

[0001] The invention relates to the technical field of dust particle metering and regulation, and in particular to a metering self-regulating device of a double-cavity multi-channel dust particle counter. Background Art

[0002] Dust particle inspection and monitoring equipment must be tested and calibrated before shipment. Traditional equipment first atomizes a standard particle source, then sprays the particles into a cavity through a nozzle, and uses a standard particle metering device for measurement. The staff must repeatedly adjust the amount of spraying to make the particles reach a low concentration, and then perform low-concentration inspection and calibration on a single dust particle inspection and monitoring equipment. After measuring the low concentration, the staff must also adjust the particle concentration to a high concentration. The high-concentration inspection and calibration process for a single dust particle inspection and monitoring equipment is time-consuming and labor-intensive.

[0003] In the existing public documents, the invention patent with patent publication number CN102221520A discloses a laser dust particle counter. This technology mainly uses a pressure regulating valve set between the air inlet and the high-pressure gas supply device and a pressure differential meter for measuring the pressure difference between the pressure in the air cavity and the atmospheric pressure. This enables the laser dust particle counter of the present invention to provide a buffer process for the sampling of high-pressure gas, so that the laser dust particle counter can obtain a stable sampling flow rate, and then effectively measure the particle size distribution of dust particles in the high-pressure gas to be measured. However, this technology still has the following problems.

[0004] During the measurement process of the dust particle counter, although the number of dust particles can be detected by sensing, during the detection process, since the number of dust particle counter monitoring devices to be detected is large, it is necessary to adjust the low concentration one by one for detection, and then adjust to high concentration and then detect the dust particle counter monitoring devices one by one. This makes it difficult to achieve self-adjustment and efficient detection of the monitoring devices of multiple dust particle counters, and the detection efficiency is greatly reduced. For this reason, a dual-cavity multi-channel dust particle counter measurement self-adjustment device is needed. Summary of the invention

When the shaft rotates ninety degrees clockwise, the positioning hole disk and the low-concentration cavity are connected through the multi-channel hole disk, so that the sensor ends of multiple dust particle counter monitoring devices can measure the low-concentration dust particles inside the low-concentration cavity.

[0014] When this technology is used, the booster air pump pressurizes the connecting pipe by docking the dust particle test hopper to the inner wall of the dust inlet pipe on the boost pipe, and docking another dust particle test hopper to the dust inlet pipe on the branch pipe. At the same time, the connecting pipe diverts the pressurized air to the inside of the boost pipe and the inside of the branch pipe, and enters the low-concentration cavity through the locking valve. When the number of dust particles in the low-concentration cavity is the number of low-concentration dust particles set by the controller, the locking valve is closed by the controller.

[0016] 1.

[0017] 2. The present invention uses a displacement detection component to enable the reduction motor to drive the linkage screw to rotate, and the linkage screw rotates inside the slide frame. The linkage screw drives the sleeve block to move right under the action of the thread transmission force, and the sleeve block drives the support ring to move right. Then, the rotation motor is started to drive the visual camera to rotate forward 90 degrees, and then the rotation motor is used to start the visual camera to reverse 180 degrees. The visual camera can collect the displayed values ​​on the display screens of multiple dust particle counter monitoring devices on the positioning plate, and compare them with the low-concentration dust particle values ​​of the low-concentration cavity set by the controller. Then, the visual camera continues to collect the displayed values ​​on the display screens of multiple dust particle counter monitoring devices, and can realize low-concentration and high-concentration rapid adjustment and switching detection for the sensor ends of multiple dust particle counter monitoring devices, thereby greatly improving the self-adjustment detection efficiency of dust particle metering.

[0018] 3. The present invention uses a dual-chamber adjustment and detection mechanism, and the boost air pump boosts the pressure of the connecting pipe. At the same time, the connecting pipe diverts the pressurized air to the inside of the boost pipe and the inside of the branch pipe. The particle metering sensor inside the low-concentration cavity performs dust particle metering operations. When the number of dust particles inside the low-concentration cavity is the low-concentration dust particle number set by the controller, the locking valve is closed by the controller, and the particle metering sensor inside the high-concentration cavity performs dust particle metering operations.

In this way, a low-concentration dust particle detection state can be quickly formed inside the low-concentration cavity, and a high-concentration dust particle detection state can be quickly formed inside the high-concentration cavity.

[0019] According to the mutual influence of the above-mentioned multiple effects, firstly, a low-concentration dust particle detection state is quickly formed inside the low-concentration cavity, and at the same time, a high-concentration dust particle detection state is quickly formed inside the high-concentration cavity. Then, the sensor ends of multiple dust particle counter monitoring devices are squeezed and locked. The sensor ends of multiple dust particle counter monitoring devices can measure and detect low-concentration dust particles inside the low-concentration cavity. The sensor ends of multiple dust particle counter monitoring devices can synchronously and efficiently measure high-concentration dust particles inside the high-concentration cavity. Finally, the visual camera can collect and compare the displayed values ​​on the display screens of multiple dust particle counter monitoring devices on the positioning plate. In summary, self-adjusting and efficient detection can be achieved for the monitoring equipment of multiple dust particle counters, and the detection efficiency is greatly improved.

The outer wall of the connecting pipe 34 is fixedly connected with a shunt pipe 36 located on one side adjacent to the booster air pump 35. One end of the shunt pipe 36 is threadedly connected with a throttle valve 37, and a stamping valve 38 is fixedly installed on one side of the throttle valve 37; the top of the outer wall of the booster pipe 30 and the branch pipe 33 are fixedly connected with a dust inlet pipe 39, and one side of the inner wall of the low-concentration cavity 28 and the high-concentration cavity 31 are fixedly connected with a particle metering sensor 41; the branch pipe 33 is fixedly connected to the mounting plate 1.

The vertical cross-section of the connecting pipe 34 is concave, and the inner wall of the connecting pipe 34 is a smooth surface.

[0039] The method of using the dual-cavity multi-channel dust particle counter metering self-adjusting device of the present invention is as follows:

[0040] Step 1: During the double-chamber adjustment test, firstly, multiple dust particle counter monitoring devices are placed in the positioning grooves of the positioning plate 20, and then multiple dust particle counter monitoring devices are placed side by side, and then the sensor ends of multiple dust particle counter monitoring devices are inserted into multiple holes inside the positioning hole plate 8. Then, by docking the dust particle test hopper to the inner wall of the dust inlet pipe 39 on the boosting pipe 30, and docking another dust particle test hopper to the dust inlet pipe 39 on the branch pipe 33, the boosting air pump 35 is started, and the boosting air pump 35 pressurizes the connecting pipe 34. At the same time, the connecting pipe 34 diverts the pressurized air to the inside of the boost pipe 30 and the inside of the branch pipe 33. The pressurized air blows the dust particles inside the boost pipe 30 into the locking valve 29, and enters the low-concentration chamber 28 through the locking valve 29. At the same time, the particle metering sensor 41 inside the low-concentration chamber 28 performs dust particle metering operation. When the number of dust particles inside the low-concentration chamber 28 is the number of low-concentration dust particles set by the controller 40, the locking valve 29 is closed by the controller 40.

[0041] At the same time, the connecting pipe 34 conveys the pressurized air to the branch pipe 33, and the branch pipe 33 conveys the dust particles to the connecting valve 32 with pressurization, and then pours them into the high-concentration chamber 31 through the connecting valve 32. The particle metering sensor 41 inside the high-concentration chamber 31 performs the dust particle metering operation. When the number of dust particles inside the high-concentration chamber 31 reaches the high-concentration metering value set by the controller 40, the connecting valve 32 is closed by the controller 40. At the same time, the throttle valve 37 is opened and the stamping valve 38 is closed, so that a part of the air between the stamping valve 38 and the throttle valve 37 is pressurized, and then the throttle valve 37 is closed, and the controller 40 also closes the booster air pump 35.

[0042] Step 2: During synchronous docking adjustment, the electric cylinder 17 is supported by the switch hole plate 5, and the electric cylinder 17 pushes the concave block 16, and the concave block 16 drives the hinge shaft 15 to push, and the hinge shaft 15 drives the bottom end of the sleeve rod 14 to push up, and at the same time, the sleeve rod 14 drives the linkage shaft 13 to rotate counterclockwise, and the linkage shaft 13 drives the hinge block 12 to rotate counterclockwise. The hinge block 12 makes one of the arc pressure plates 11 rotate counterclockwise, and the arc pressure plate 11 drives the connecting sleeve shaft 10 to rotate counterclockwise, and the connecting sleeve shaft 10 rotates counterclockwise along the outer wall of the support shaft 9, and the connecting sleeve shaft 10 synchronously drives the other three arc pressure plates 11 to rotate synchronously, so that multiple arc pressure plates 11 can squeeze and lock the sensor ends of multiple dust particle counter monitoring devices, and then the controller 40 can close the electric cylinder 17.

[0043] Then the controller 40 starts the driving motor 7, and the driving motor 7 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the switching hole plate 5 to rotate clockwise, and the switching hole plate 5 drives the sealing hole pad 4 to rotate on the multi-channel hole strip 3. At the same time, the switching hole plate 5 drives the positioning hole plate 8 to rotate, so that the multi-channel hole plate 2 can support the bracket 19, and the bracket 19 supports the angle sensor 18. The angle sensor 18 realizes angle sensing of the rotating shaft 6. When the rotating shaft 6 rotates ninety degrees clockwise, the positioning hole plate 8 and the low-concentration cavity 28 are connected through the multi-channel hole plate 2, so that the sensing end of the multiple dust particle counter monitoring devices can measure the low-concentration dust particles inside the low-concentration cavity 28, and the numerical value can be displayed on the display screen of the multiple dust particle counter monitoring devices after measurement.

[0044] Step 3: During low-concentration displacement detection, the controller 40 starts the reduction motor 23, which drives the linkage screw 22 to rotate. The linkage screw 22 rotates inside the slide frame 21. At the same time, the linkage screw 22 drives the sleeve 24 to move right under the action of the thread transmission force, and the sleeve 24 drives the support ring 25 to move right. The support ring 25 causes the rotating motor 26 to move right, and the rotating motor 26 drives the visual camera 27 to move right. After the visual camera 27 moves right, the rotating motor 26 is started to drive the visual camera 27 to rotate forward by 90 degrees, and then the rotating motor 26 is used to start the visual camera 27 to reverse by 180 degrees. In this way, the visual camera 27 can collect the displayed values ​​on the display screens of the multiple dust particle counter monitoring devices on the positioning plate 20, and compare them with the low-concentration dust particle values ​​of the low-concentration cavity 28 set by the controller 40. If they meet the low-concentration dust particle values ​​set by the controller 40, the multiple dust particle counter monitoring devices are in a qualified state. If they are different, the multiple dust particle counter monitoring devices have detection abnormalities.

[0045] Step 4, during high-concentration displacement detection, after low-concentration detection, the drive motor 7 is started, and the drive motor 7 drives the shaft 6 to rotate, and the shaft 6 drives the switching hole plate 5 to continue to rotate ninety degrees, and the switching hole plate 5 drives the positioning hole plate 8 to continue to rotate ninety degrees, and the positioning hole plate 8 rotates to the left side of the stamping valve 38. After opening the stamping valve 38, the pressurized air between the stamping valve 38 and the dust inlet pipe 39 can realize the pressurized cleaning operation on the sensor ends of the multiple dust particle counter monitoring devices inside the positioning hole plate 8. After cleaning, continue to drive the shaft 6 to rotate another ninety degrees through the drive motor 7, so that the positioning hole plate 8 can be rotated to a position connected to the high-concentration chamber 31, so that the positioning hole plate 8 and the high-concentration chamber 31 are connected through the multi-way holes. The disk 2 is connected, and the sensor ends of the multiple dust particle counter monitoring devices can measure the high-concentration dust particles inside the high-concentration cavity 31. After measurement, the values ​​can be displayed on the display screens of the multiple dust particle counter monitoring devices.
