Description
Technical field
The present invention relates to and relate to engineering machinery field, more particularly, particularly a kind of breaker.
Background technology
Coal is a kind of solid combustible organic rock, and it is by plant remains through biological chemistry action, changes forming after burying again through geologic process.Coal is described as the gold of black by people, the grain of industry, one of main energy sources that since it was 18th century, human world uses.The essential element contained in coal is carbon, hydrogen, oxygen, nitrogen, accounts for more than 95%, and remaining element comprises sulphur, phosphorus, fluorine, chlorine and arsenic etc.Carbon and hydrogen are the elements producing heat in coal burning process, and oxygen is combustion-supporting element.During coal burning, nitrogen does not produce heat, is at high temperature transformed into oxynitrides and ammonia, separates out with free state.Sulphur, phosphorus, fluorine, chlorine and arsenic etc. are the harmful components in coal, wherein important with sulphur.During coal burning, the sulphur of the overwhelming majority is oxidized to sulfur dioxide (SO2), with fume emission, and atmosphere pollution, the growth of harm animal and plant and human health, corroding metal equipment; When the coal that sulfur-bearing is many is used for metallurgical coking, also affect the quality of coke and iron and steel, therefore " sulphur content " content is one of important indicator evaluating ature of coal.
In production process, for obtaining comprehensive understanding to the quality of coal, the good and bad grade of evaluation coal, usually needs first to utilize sampling machine to carry out sample preparation to coal, then detects the sample completed.Sample preparation refers to and can represent for obtaining a result of the test test coal sample being sampled coal by the gross.The basic process of sample preparation is that i.e. elementary increment, then carries out division by each elementary increment, finally obtains the test coal sample of satisfactory defined amount and type first from a considerable amount of a coal of many collections being distributed in coal by the gross.The basic demand of sample preparation is that all particles being sampled batch coal all may enter sample devices, and each particle has equal probability to be adopted in sample.
In coal sample making course, need to carry out division.So-called division, refers to that the fragmentation of material is reduced and samples with branch.In the process, coal needs first to be broken into 25mm from particle diameter 50mm size, then carries out just minor tick sampling; The coal of the particle diameter 25mm then primary sample obtained is broken into 13mm again, then therefrom interval second time sampling ..., finally, coal is crushed to particle diameter 0.2mm size, then therefrom chooses satisfactory sample.Due to the limitation of existing reducing mechanism structural design, granule size very bad control when existing disintegrating machine carries out fragmentation to material, control discharging-material size by the size in sieve plate hole mostly, so be easy to cause sieve plate buildup, finally cause disintegrating machine to block, cause stopping accident, and material particle size after cracking size can not regulate, material will be broken into different granularities, can only change different sieve plates; In addition, after conventional breaker uses a period of time, along with the wearing and tearing in sieve plate hole, discharging-material size can become large gradually, has a strong impact on the broken precision of material.
In sum, how a kind of fragmentation that effectively can realize various different-grain diameter size material is provided, effectively can prevents feed blocking again, guarantee that the breaker of the broken precision of material becomes those skilled in the art's problem demanding prompt solution.
Summary of the invention
