Dense phase pneumatic conveying system of high-efficiency energy-saving heavy material

Abstract

The invention relates to a dense phase pneumatic conveying system of a high-efficiency energy-saving heavy material, which has the main technical characteristics: (1) upward guide discharge is adopted, and an umbrella-type discharge hole device is arranged at the end of a discharge tube; (2) a discharge tube in a communicating pump body below a discharge valve is a double casing pipe; (3) bottom fluidization components which is connected by flanges are coaxially arranged at the bottom of the pump body. The invention has small volume and low requirement on the pressure of an air source, and compressed air of 0.8MPa can meet the requirement; the invention is controlled by a programmable controller, and therefore, the degree of automation is high, the running is stable and the operation is convenient; the floor area of the system can be greatly reduced, the investment cost of foundation construction, factory construction and the like of a dedusting system is reduced, and the blank of domestic conveying equipment of the heavy material is filled; compared with the foreign technology, the system makes good for deficiency and has the advantages of small volume, small floor area, easy maintenance and the like.

Description

technical field [0001] The technical innovation of the invention belongs to the field of pneumatic conveying, in particular to a high-efficiency and energy-saving dense-phase pneumatic conveying system for heavy materials. Background technique [0002] At present, in the heavy metal material pneumatic conveying system, 4.1t / m 3 The material conveying system with a specific gravity above is still a blank in the domestic conveying industry, so foreign equipment has been used for a long time, but the foreign equipment must use a 1.4Mpa air compressor to meet the pressure requirements of the system using a 1.2Mpa air source. Due to the high delivery pressure of the system, severe wear and tear of pipes and valves, low work efficiency and high system operation and maintenance costs. At present, the country vigorously advocates energy saving and consumption reduction, and at the same time, users are eager to replace the original system with low-consumption and high-efficiency con...
