Dynamic full performance test system for multifunctional belt balance

Abstract

The invention relates to a multifunctional belt balance dynamic overall-performance testing system with relatively less occupied area and investment, and is suitable for belt conveyors with a plurality of belt width and groove-shaped angles. The system can test both an embedded type belt balance and an integrated type belt balance, and can develop both a test project of a metering belt balance and the test project of a quantitive belt balance. The system is characterized in that a plurality of the belt conveyors with different belt width and length are mounted in different elevation by layers (at least two layers) and are close end to end; the end-to-end close part is provided with pits or feed bins which are used for continuing or caching of a tested material; at least one of the pits or feed bins is used as control weighing equipment for a high-precision hopper balance; and each conveyer can adopt a layout of a reciprocating return or annular continuous mode. Each long conveyer can be embedded with the metering belt balance to be tested with corresponding belt width; and an integrated-type quantitive belt balance to be tested can be conveniently rearranged on a short belt conveyer part. In testing, a material entering the bottom layer the pit is lifted to the feed bin of the top layer by the belt conveyor with a large slope angle and is recycled and utilized time and again.

Description

technical field [0001] The present invention relates to a novel test system for continuous accumulative automatic weighing apparatus, in particular, it relates to a test platform and its equipment layout which can carry out diversified dynamic performance tests on belt scales of various types and specifications. Background technique [0002] The belt scale is an automatic weighing instrument for dynamic accumulative weighing of the bulk materials continuously conveyed by the conveyor belt. The weight of the material is not consistent during the weighing process, and the conveyor belt is not a rigid body, so its dynamic measurement performance is inseparable from the performance of the conveyor and its belt. Like a static scale, it is necessary to directly load a fixed mass weight for value transmission. impossible. The world-recognized only traceable method of belt scales is physical verification, that is, the material weighed by the belt scale is weighed by a non-automatic...

Problems solved by technology

[0004] At present, due to the lack of corresponding testing methods, domestic quality inspection and supervision agencies can only use non-belt simulation tests or static tests to replace the type evaluation of the products of the manufacturer. The disadvantages are: the test results are not consistent with the real performance of the products Th
