Problems solved by technology

For the water treatment industry: when adding PAM powder, after other vacuum feeders have been running for a period of time, due to the inherent characteristics of PAM that is easy to absorb moisture, the filter is easily blocked by PAM, resulting in a decrease in the filtration area and failure to operate normally. use
More importantly, it does not solve the problem of accurate dosing in the process of conveying materials

Abstract

The invention provides a vacuum feed device. The device is characterized by comprising a vacuum separating device, a bin storage device and a material conveying device which are connected in sequence. The device has the advantages that: as thread pitch of a feed screw and rotating speed of a motor are determined, quantitative feed of a material is ensured in unit time; a back flowing device is added to ensure that the material is prevented from adhering on a filter, thereby achieving integration of loading and accurate feed, meanwhile, the device has a special effect on a material with large adherence, and solves the never solved problem of PAM feed in the water treatment industry because of large adherence; in PLC, the rotating speed of the motor can be changed through setting parameters so as to change the volume of feed amount, thereby achieving that integration of vacuum loading and material accurate feed is completely controlled by PLC, greatly reducing man power, and improving the production efficiency.

Description

technical field [0001] The invention provides a vacuum feeding device, which is used in the water treatment industry and belongs to the technical field of feeding devices. Background technique [0002] With the rapid development of science and technology and production, people have put forward higher requirements for the transportation and precise dosing of materials. In the water treatment industry, the precise metering and dosing of polyacrylamide (PAM) directly affects the treatment effect of sludge; at the same time, in order to reduce labor intensity, the material is carried to the storage bin by means of high-speed airflow, which improves the automation of the equipment. The manual participation process is reduced, the labor force is liberated, and labor efficiency is improved. [0003] The current conventional vacuum feeder only solves the feeding problems of other industries, and has no special effect on the water treatment industry. Secondly, other vacuum feeders d...
