Vacuum sucking and feeding system with back flushing function

Abstract

The invention relates to a vacuum sucking and feeding system with a back flushing function. The vacuum sucking and feeding system comprises two sets of feeding mechanisms, two sets of regulation devices, an adding device and a source water adding mechanism, wherein bag breaking machines are arranged on the lower sides of container bags; feeders are arranged at the bottoms of the bag breaking machines; powder conveyors and water control dedusting devices are arranged at the tops of the regulation devices; the powder conveyors are connected with the bottoms of the feeders through pipelines; the source water adding mechanism is communicated with the tops of the regulation devices; the adding device is communicated with the bottoms of the regulation devices; a back flushing device comprises a pre-pumping flushing device, a post-pumping flushing device and a first flushing device; the first flushing device is connected with one end of a liquid-out pipe; the pre-pumping flushing device is connected with the middle of the liquid-out pipe and an adding pump; the post-pumping flushing device is connected with an adding tube. The vacuum sucking and feeding system has the following advantages: as the back flushing device is arranged, the pipelines in the whole system can be flushed after adding, the interiors of the pipelines are prevented from dirt, the product adding quality is improved, and the equipment service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of material conveying and dosing equipment, in particular to a vacuum suction and feeding system with backwashing function. Background technique [0002] At present, in the field of powder dosing technology, there are the following problems: the pollution problem of powder flying in the application, the working environment is harsh, the fastness is high during loading and unpacking, unpacking, preparation, and dosing, and the precise quantitative dosing in the application is difficult to control. The degree of automation is low, and it is difficult to give full play to the advantages of powdered activated carbon technology due to the failure to solve the limitations of the technology in application. Contents of the invention [0003] The present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited only to the examples. ...
