Scale calibrating device and scale calibrating method for hopper scale with hopper or hopper bin horizontal detection

Abstract

The invention relates to a scale calibrating device and a scale calibrating method for a hopper scale with hopper or hopper bin horizontal detection. The device mainly comprises a jack, a portal frame, a magnetic level instrument, a magnetic level instrument connection hose, a pressure applying platform, a standard weighing sensor and a weighing display instrument, wherein the lower end of the central position of a horizontal transverse beam of the portal frame is provided with the jack; the jack is vertically arranged on the upper surface of the standard weighing sensor for scale calibrating; the pressure applying platform is arranged below the standard weighing sensor for scale calibrating; and the magnetic level instrument mainly comprises a magnetic base and a plastic pipe with graduations. The jack is used for converting a standard weight needed by electronic scale calibration into mechanical force instead of a weight, the magnitude of applied force is controllable, and the loading is at a uniform speed and is reliable; the magnitude of the applied force is accurately displayed through the standard weighing sensor and the weighing display instrument, so that the accurate metering of mechanical force is realized; and the scale calibrating device has a simple structure and a low price, is suitable for narrow fields, can be used repeatedly, is flexible and convenient for applying, and is convenient to install and use on site.

Description

technical field [0001] The invention relates to a measurement correction and calibration device, in particular to a hopper scale calibrating device with hopper / silo level detection and a calibrating method using the device. Background technique [0002] The hopper / silo scale can be used as a material level detection (convert the weight of the material weighed in a certain volume of the silo into the material height, that is, the material level), such as the detection of the material level of the silo in the sintering project; it can also be used as a batching scale, For example, the weighing ratio of coke and ore in the process of blast furnace ironmaking and converter steelmaking is an extremely important process link. The accuracy of the weighing is directly related to energy saving and consumption reduction and product quality. Therefore, Hoppers are widely used in industrial production. The hopper scale is usually composed of a weighing hopper / silo and an electronic sca...

However, this method requires multiple handling of the weights, which is labor-intensive and low in labor efficiency.

In the process of loading weights, the display accuracy of the electronic scale is also directly related to the position of the weights. If the weights are placed unevenly and the eccentric load is large, it will lead to calibration failure, or even damage due to uneven load distribution due to inclination. Load cell, at the same time, if the weights are not placed properly, it may cause collapse and hurt people
