Embodiment Construction

[0042] Combine below Figure 1 to Figure 6 Embodiments of the present invention are described in detail.

[0043] The intelligent coal sample quantitative weighing device includes a porcelain boat 1 for holding coal samples and a weighing component 2 for weighing the coal samples in the porcelain boat 1, and is characterized in that it also includes placing the porcelain boat 1 on the scale The lifting and rotating mechanism 3 that removes the porcelain boat 1 from the weighing assembly 2 and the vibrating sampling mechanism 4 that adds coal samples to the porcelain boat 1 by vibration. The vibrating sampling mechanism 4 is located on the scale Right above the heavy component 2, the ceramic boat 4 is placed on the weighing component 2 with the movement of the lifting and rotating mechanism 3, and receives the coal sample that vibrates and falls from the vibrating sampling mechanism 4. The weighing component 2, the lifting and rotating mechanism 3 and the vibration The sample ...

Abstract

The invention discloses an intelligent coal sample quantitative weighing device and method. The device comprises a porcelain boat for placing a coal sample and a weighing module for weighing the coalsample in the porcelain boat. The weighing device is characterized by further comprising a lifting rotary mechanism for placing the porcelain boat on the weighing module or taking off the porcelain boat from the weighing module, and a vibration sampling mechanism for adding the coal sample in the porcelain boat by adopting a vibration way; the vibration sampling mechanism is located above the weighing module, the porcelain is placed on the weighing module along with the movement of the lifting rotary mechanism, and receives the coal sample falling from the vibration sampling mechanism due to vibration; the weighing module, the lifting rotary mechanism and the vibration sampling mechanism are cooperatively controlled by the control system in a unified way. The placing or taking-off of the porcelain boat on the weighing module is realized through the lifting rotary mechanism, the trace and step-by-step sample falling in the porcelain boat can be performed through the vibration sampling mechanism, thereby precisely controlling the adding quantity and adding time of the coal sample. the precise and reliable and full-automatic and intelligent quantitative weighing is realized, the quantitative weighing process is free from artificial participation, and the efficiency and the accuracy are higher.

Description

technical field [0001] The invention relates to an intelligent coal sample quantitative weighing device and method, which are used for quantitative and accurate weighing of coal samples. Background technique [0002] The sulfur content in coal is different. In order to reduce the emission of sulfur dioxide, the total sulfur content in the coal must be measured first. The sulfur meter is the main instrument for measuring the sulfur content in coal (the microcoulomb method is used for the determination of sulfur content in petroleum). Coal production departments and coal-using departments such as fertilizer, power generation, civil, coking and building materials all attach great importance to the analysis of total sulfur in coal. The sulfur meter is mainly used to measure the total sulfur content in coal, steel and various minerals. It is an essential instrument for laboratories in departments such as coal, electric power, chemical industry, building materials, metallurgy, geo...
