A material vacuum conveying system and its application method

Abstract

The invention relates to a material vacuum conveying system and a usage method thereof. The system comprises a control system, a discharging tank, a vacuum pump and an air compressor, wherein the discharging tank is provided with a charging port and a discharging port, the vacuum pump and the air compressor are connected with the discharging tank respectively, and valves controlled by the control system are arranged at connecting positions, the position of the charging port and the position of the discharging port. According to the method, when two-phase separation and discharging are required to be performed on materials inside the tank, a bubble generator is started firstly, a current of an electrode is adjusted to separate a light phase from a heavy phase, then a heavy-phase discharging port valve is opened to discharge the heavy-phase materials, finally, a light-phase discharging port valve is opened, and after all materials are discharged, the air compressor and all valves are shut down. According to the system, both material conveying and light-and-heavy-phase separation can be performed, and the system is low in energy consumption, free of abrasion, high in material adaptability, high in stability and applicable to fluids or semi-fluid complicated materials of different moisture contents.

Description

technical field [0001] The invention relates to the field of material conveying, in particular to a material vacuum conveying system and an application method thereof. Background technique [0002] The transportation of viscous, heterogeneous and complex materials has always been a problem in the industry. This type of material contains many large pieces of plastic, hard porcelain, sand and metal foreign objects. The complex material properties determine its difficulty in transportation and investment. larger. At present, most of the equipment for conveying this kind of material are hydraulic plunger pumps, screw pumps, and screw conveyors. However, in actual use, it is found that there are still some shortcomings, so the best use effect cannot be achieved. The shortcomings can be summarized as follows: [0003] 1. Semi-fluid materials have low moisture content and poor fluidity. If the traditional pump discharge system is used, the low fluidity will lead to low pumping ef...
