Slurry canning device and canning method

Abstract

The invention discloses a slurry canning device and method, and belongs to the technical field of slurry conveying and packaging. Comprising a slurry packaging barrel, an opening is formed in the slurry packaging barrel, and a sealed exhaust barrel is installed above the opening; the sealing exhaust barrel comprises an exhaust cavity and a sealing device, an exhaust hole communicated with the exhaust cavity is formed in the top of the sealing device, an air inlet pipe penetrating through the exhaust cavity and entering the slurry packaging barrel through the opening is installed on the exhaust cavity, and a feeding pipe stretching into the slurry packaging barrel is installed in the air inlet pipe. The top of the sealing device is further provided with an air inlet hole communicated with an air inlet pipe, and an exhaust channel communicated with the exhaust cavity is arranged between the outer wall of the air inlet pipe and the outer wall of the opening of the slurry packaging barrel. The device has the beneficial effects that the sealing protection structure is arranged on the periphery of the gas inlet pipe, a closed gas protection system with small-ring feeding, middle-ring shielding gas feeding and large-ring exhausting is formed, gas leakage can be well blocked, dismounting and mounting are convenient, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of slurry conveying and packaging, in particular to a slurry filling device and a filling method. Background technique [0002] When filling the existing slurry packaging barrels, the feeding port of the barrel is directly connected with the silk thread of the pipeline for filling. In this way, there is a problem that the air in the packaging barrel cannot be discharged in time during filling. For toxic and flammable Gas, there is a great potential safety hazard, and it cannot meet the requirements of accurate weight when weighing and measuring; the existing filling devices basically use metal hoses as guide tubes to feed, but during the feeding process due to material discharge The impact force will cause the stationary metal hose to swing, thus affecting the weighing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a slurry tanking device capa...
