  • Patent number: 11324101
    Abstract: An active fluid static elimination system installed in a fluid transportation pipeline includes a solenoid valve, an electrostatic measuring device, a fluid destaticizer, and a controller. The solenoid valve is connected to a connecting port of the fluid transportation pipeline, and the electrostatic measuring device is used to measure an electrostatic value of a fluid in the fluid transportation pipeline. The fluid destaticizer is connected to the solenoid valve, and the controller is connected to the electrostatic measuring device and the solenoid valve. The solenoid valve is opened to allow the fluid passing through the fluid destaticizer to eliminate the electrostatic charge of the fluid when the controller determines that the electrostatic value measured by the electrostatic measuring device is greater than a predetermined value.

  • Patent number: 11203451
    Abstract: A multifunction cap replacement module includes a cap rotation module supporter and at least one cap rotation module. The cap rotation module is mounted to the cap rotation module supporter, and the cap rotation module includes a first cap rotation device and a second cap rotation device. The first cap rotation device is configured to open one sealing cap of at least one chemical drum and extract a chemical liquid from the chemical drum, and the second cap rotation device is configured to open another one sealing cap of the chemical drum and allow the chemical liquid to flow back to the chemical drum.

  • Publication number: 20210347514
    Abstract: An integrated cap rotation equipment includes a cap rotation module supporter and a cap rotation module. The cap rotation module includes a cap rotation device, an integrated connecting device and an optical detector. The cap rotation device is used to open a sealing cap of at least one chemical storage container, and the integrated connecting device is used to connect an opening of the chemical storage container to extract a chemical liquid from the chemical storage container and return the chemical liquid to the chemical storage container. The optical detector is disposed between the cap rotation device and the integrated connecting device, and is used to detect the position of the sealing cap of the chemical storage container, so that the cap rotation device and the integrated connecting device are able to align with the sealing cap and the opening, respectively.

  • Patent number: 11027965
    Abstract: A cap rotation device includes a cap rotator, a liquid transferring device and an optical detecting device. The liquid transferring device is disposed near the cap rotator, and the optical detecting device is disposed between the cap rotator and the liquid transferring device. The optical detecting device is used to detect a position of a sealing cap of a chemical drum to guide the cap rotator aligning with the sealing cap. Therefore, the sealing cap is opened by the cap rotator, and then the chemical liquid is transferred by the liquid transferring device.
