Impact-free interference removal high-precision gravimetric feeder

Abstract

The invention belongs to mine, metallurgy and port equipment, and particularly relates to an impact-free interference removal high-precision gravimetric feeder. The feeder consists of a receiving part and a weighing transfer part, wherein the receiving end of the weighing transfer part is positioned at the discharge hole of the receiving part. The gravimetric feeder has reasonable and compact structure, optimized weighing mode, no interference, low fault and high precision.

Description

technical field [0001] The invention belongs to mining, metallurgy and port equipment, in particular to a high-precision weighing feeder free from impact and interference. Background technique [0002] At present, the more advanced gravimetric feeding systems in mines, metallurgy, and ports include dynamic gravimetric feeders and fixed-weight loading devices, which have been widely used in production.

Problems solved by technology

However, due to the unreasonable structural design, there are many shortcomings. It is necessary to further improve the weighing accuracy in terms of structure and weighing methods, and reduce its own shortcomings such as easy damage and difficult maintenance. Dynamic weighing feeder and fixed weight loading device Similarly, there are the following problems: (1) The material receiving part and the weighing and reloading part are integrated. In order to prevent the material from being impacted, the whole machine is equipped with armored belts, steel tracks or thickened belts, and built-in rigid objects in the belts, etc. As a result, the weight of the feeder itself is very large, and the power consumption for starting and running is large; (2) The resource consumption of the equipment itself is large, and the failure rate is high. The whole machine needs to be disassembled during maintenance, which consumes a lot of manpower and material resources and takes up a lot of production time. (3) There is no radical anti-smashing buffer device, so that the receiving part is easily damaged by smashing, and the failure rate is high; (4) The receiving part of the integrated fuselage is impacted by materials falling from a height of tens of meters When the conveyor belt is seriously deformed, the conveyor belt sinks and pulls back, which seriously affects the weighing accuracy; (5) Due to the different materials of the belt and the armor belt, the elongation in use is different, and multiple tensions need to be increased. Changes and barriers of armor belts and steel tracks have seriously affected the stability, accuracy, and sensitivity of weighing. Due to the need for frequent tension adjustments and calibrations, it takes up a lot of production time and reduces efficiency; (6) the belt Thickening or built-in rigid objects in the belt prevent impact, making the belt too hard, hindering the gravity transmission of the material, resulting in inaccurate measurement, etc.
