Suction device

Abstract

The embodiment of the invention provides a suction device. The suction device comprises a suction pipe and an air inlet device, wherein the air pressure inside the suction pipe is lower than the air pressure of the outside, the air inlet device is connected with a suction port of the suction pipe to provide airflow for the suction port, the suction port is inserted into a powder pile, and then powder enters the suction pipe through the suction port. When the suction device is used for sucking in powder with a small size, the suction port can not be blocked, and suction can be conducted smoothly.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a suction device. Background technique [0002] Due to the needs of work, some industries often use powder materials. For example, in the field of tap water purification, it is often necessary to use a large amount of powder carbon or lime to ensure water quality. These powders need to be bagged during transportation, and are generally stacked in piles during storage. Therefore, in actual use, a suction device is often used to suck from the powder pile. [0003] Now the commonly used suction device is a vacuum suction machine. Insert the vacuum suction machine into the powder pile, and the powder will be sucked into the corresponding equipment through the vacuum suction machine. The vacuum suction machine can reduce powder scattering and maintain environmental sanitation. It plays a positive role in protecting the health of workers and reducing labor intensity. [0004] But at present, t...
