Environmentally friendly fully enclosed bulk bulk sample preparation system

Abstract

The invention discloses an environment friendly and totally enclosed sample preparation system for bulk materials. The environment friendly and totally enclosed sample preparation system comprises a feeding machine (1), a crusher (2), a splitter (3) and a sample aggregator (4) and is characterized in that the feeding machine (1), the crusher (2), the splitter (3) and the sample aggregator (4) are arranged vertically from top down, a discharge port and a feed opening are in butt joint in sequence, and a totally enclosed structure is integrally formed. The environment friendly and totally enclosed sample preparation system has the advantages that the system design is reasonable, the structure is compact, the totally enclosed structure can completely avoid the phenomena of material spilling, material leakage and dust pollution, the materials falls under the effect of gravity, a belt conveyor is not required to be equipped, the energy consumption is reduced largely, and the sample preparation precision is improved remarkably.

Description

technical field [0001] The invention relates to the technical field of bulk material collection and sample preparation equipment, in particular to a material collection and sample preparation system with the functions of feeding, crushing, dividing, collecting and discarding samples. Background technique [0002] Bulk bulk materials, especially coal and ore, are my country's main energy sources and one of the main commodities for my country's import and export earnings. With the development of international and domestic market economies, its circulation will be further strengthened. [0003] For example, coal, as a commodity, is unique in that it is a heterogeneous bulk, and its properties vary greatly depending on the place of origin, and its quality also varies greatly due to different mining methods, storage and transportation methods, and management levels. big difference. In addition, various industrial uses have different quality requirements for coal types, so the ev...

AI Technical Summary

Problems solved by technology

[0008] First, the two-stage belt conveyors are all open structures. During the falling process of materials, coal spilling, coal leakage and dust pollution will inevitably occur. Regular cleaning is required, which not only increases the labor intensity of the staff, but also does not meet the requirements Environmental protection requirements, operators are in a harsh environment, and long-term inhalation of excessive dust is likely to cause occupational diseases such as pneumoconiosis, which does not meet the requirements of safe production. Although this pollution phenomenon can be moderately reduced by installing protective equipment, it cannot be solved fundamentally

[0009] Second, due to coal sprinkling, coal leakage and dust pollution, it is easy for the belt feeder itself and other equipment to break down due to dust entering key parts such as transmission, and the maintenance rate is high

[0010] Third, the arrangement of the belt conveyor needs to have a certain length, so it occupies a large area, which not only leads to a large volume of the entire sample preparation system, but also increases the difficulty of the arrangement of other equipment

[0011] Fourth, the belt conveyor is driven by a motor, and its power consumption is large, resulting in a high operating cost of the sample preparation system.
