Filling head with air-liquid duplex channel, filling system and method thereof

Abstract

The invention discloses a filling head with an air-liquid duplex channel, a filling system and a method thereof, wherein the filling head with the air-liquid duplex channel comprises a substance filling pipe for filling liquid substances and an gas filling pipe for filling a gas, the gas filling pipe is sleeved and embedded in the substance filling pipe, an feeding port and a discharge port are arranged on the substance filling pipe, a gas inlet hole and a gas outlet hole are arranged on the gas filling pipe, and the discharge port and the gas outlet hole are arranged on the same side. By the adoption of a unique design of integrating duplex channels into a whole for the filling head with the air-liquid duplex channel, functions of gas filling and liquid filling can be realized only via inserting the substance filling pipe into a stuff box. According to the design of a sealing ring on an outer periphery of the gas outlet hole of the gas filling pipe, problems of dropping and leakage after filling with liquid substance are solved. Products of filling heads provided by the invention can be applied in a fully-automated metering filling line, so when workers work in an environment with explosive gases, the filling processes and time can be reduced, the safety is increased, and the environment is not polluted.

Description

technical field [0001] The invention relates to the field of filling equipment, in particular to a gas-liquid two-way filling head, a filling system and a method thereof. Background technique [0002] At present, in the petrochemical, pharmaceutical, dyestuff, paint and other fields, for liquid materials that will undergo oxidation reactions when in contact with air, the metering and filling are mostly done manually. First, the rubber hose is used to fill the isolation gas (usually an inert gas, such as nitrogen) , and then insert another rubber hose to fill the liquid material. After filling, take out the rubber hose. Since there will be residual liquid material in the rubber hose, dripping will occur during the removal process, and two rubber hoses are used to fill the liquid material separately. The efficiency is low, and the filling time is prolonged. After the inert gas leaks, the liquid material volatilizes into the workshop, pollutes the environment, and endangers the...

[0002] At present, in the petrochemical, pharmaceutical, dyestuff, paint and other fields, for liquid materials that will undergo oxidation reactions when in contact with air, the metering and filling are mostly done manually. First, the rubber hose is used to fill the isolation gas (usually an inert gas, such as nitrogen) , and then insert another rubber hose to fill the liquid material. After filling, take out the rubber hose. Since there will be residual liquid material in the rubber hose, dripping will occur during the removal process, and two rubber hoses are used to fill the liquid material separately. The efficiency is low, and the filling time is prolonged. After the inert gas leaks, the liquid material volatilizes into the workshop, pollutes the environment, and endangers the health of workers.
