Device for automatically preparing analysis test samples of scales and corrosion products of power station

Abstract

The invention relates to a device for automatically preparing analysis test samples of scales and corrosion products of a power station. The device comprises a pedestal and a square bracket fixedly mounted on the pedestal, wherein a motor is fixedly mounted in the middle of the top end of the bracket; a motor shaft is vertically downward; the lower end part is fixedly connected with an upper grinding disc; blanking holes are formed in the upper grinding disc; upper grinding agate particles are formed on the lower surface of the upper grinding disc; a lower grinding disc is fixedly mounted below the upper grinding disc through a cross beam fixedly connected with a vertical bracket beam; lower grinding agate particles are formed on the upper surface of the lower grinding disc; powder leakage holes are formed near the edge of the lower grinding disc; a 120-mesh sieve is fixedly mounted below the lower grinding disc; an electronic scale is placed below the sieve; a weight reading trigger circuit is arranged in the electronic scale; and the output of the trigger circuit is connected with a motor trigger stop module through a lead. The device realizes semi-automatic preparation of the scales and the corrosion products, and reduces the workload and the cost.

Description

technical field [0001] The invention belongs to the technical field of scale and corrosion product detection in power systems, in particular to an automatic preparation device for analysis samples of power plant scale and corrosion products. Background technique [0002] Once scaling and corrosion occur in thermal equipment, it will seriously endanger the safe and economical operation of thermal equipment. In order to understand the composition and formation reasons of scaling and corrosion products, they must be analyzed. In order to analyze the specific components, scaling and corrosion products need to be decomposed , while the scale and corrosion products of thermal power plants are generally formed under high temperature and high pressure, and the texture is relatively hard, so it is necessary to prepare the analysis sample first. At present, the preparation of scale and corrosion product analysis samples is done manually, which is time-consuming and laborious, and the ...

AI Technical Summary

Problems solved by technology

At present, the preparation of scale and corrosion product analysis samples is done manually, which is time-consuming and labor-intensive, and the labor efficiency is low. Therefore, it is necessary to develop an automatic preparation device for analysis samples to replace heavy manual work.
