Multi-channel vacuumizing device

The utility model belongs to the technical field of vacuumizing, and particularly relates to a multi-channel vacuumizing device. Comprising a vacuum tank body, a pump unit for vacuumizing the vacuum tank body, a connecting pipeline for communicating the vacuum tank body with the pump unit, a cold sinking device arranged in the vacuum tank body, and a plurality of vacuumizing branch pipes which are communicated with the vacuum tank body and are arranged around the vacuum tank body, when the vacuumizing device is used, each vacuumizing branch pipe is communicated with vacuumized equipment, and the interior of the vacuum tank body is vacuumized through the pump unit, so that each vacuumizing branch pipe arranged around the vacuum tank body is vacuumized at the same time, the vacuumizing frequency is reduced, and the efficiency is improved; the vacuumizing branch pipes are arranged around the vacuum tank body, so that the occupied space is small; meanwhile, the gas in the vacuum tank body can be condensed through
