Quantification gas-solid two-phase flow conveying device and quantification conveying system

Abstract

The invention discloses a quantification gas-solid two-phase flow conveying device. The quantification gas-solid two-phase flow conveying device comprises a material container, a quantification plunger, a material pushing air input port and a material output port, a material containing cavity is formed in the quantification plunger, the quantification plunger can move in a reciprocating mode in the material container, when the quantification plunger moves backwards, the material containing cavity is opened, materials in the material container can fill the material containing cavity, when the quantification plunger extends out, the material containing cavity can be sealed, the material pushing air input port and the material output port can communicate to the sealed material containing cavity, the material pushing air input port can be used for injecting compressed gas into the sealed material containing cavity so that the materials in the material containing cavity can be sent out fromthe material output port. The invention further provides a quantification conveying system. The quantification conveying system comprises one or more quantification gas-solid two-phase flow conveyingdevices, the one or more quantification gas-solid two-phase flow conveying devices can be configured according to specific output quantity requirements so as to meet different use requirements.

Description

technical field [0001] The invention relates to the field of powder spraying equipment, in particular to a quantitative gas-solid two-phase flow conveying device and a quantitative conveying system. Background technique [0002] In the field of powder spraying, the delivery of powder is usually carried out by using a Venturi device, that is, inserting the Venturi suction pipe into the powder container, and using the Venturi pump to create a negative pressure to extract the powder and deliver it, but the delivery volume can only be adjusted by The air pressure or air flow of the Venturi nozzle can not achieve more accurate quantitative delivery. Contents of the invention [0003] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a quantitative gas-solid two-phase flow conveying device, which can realize quantitative conveying of powder. [0004] The technical solution adopted by the present inv...
