Vanadium slag breaking hammer combined structure and breaking method

Abstract

The invention relates to the field of coarse breaking equipment for vanadium slag, and especially relates to a vanadium slag breaking hammer combined structure capable of effectively increasing the breaking efficiency for large vanadium slag, and a breaking method. The vanadium slag breaking hammer combined structure comprises a hammer head and a breaking hopper, wherein the bottom of the hammer head is provided with a convex surface, the top of the breaking hopper is provided with a concave surface, and the concave surface is matched with the convex surface at the bottom of the hammer head. According to the invention, breaking operation is realized by combining with automatic control, many tedious processes such as stacking, slag poking, grabbing and transferring are omitted, and the labor intensity of workers is reduced. The vanadium slag breaking hammer combined structure and corollary equipment are arranged in a centralized manner, regional dust removal and noise reduction treatment are facilitated, and the use field is saved. The vanadium slag breaking hammer combined structure and the breaking method are simple and mature in technical principle, high in engineering construction convenience and economical efficiency, capable of being modularly copied, capable of being widely applied to main enterprises involving vanadium slag breaking in China, and further applied to large-block material breaking in other industries, and especially suitable for processing occasions of high-efficiency breaking for large-block vanadium slag.

Description

technical field [0001] The invention relates to the field of vanadium slag coarse crushing equipment, in particular to a combined structure of a vanadium slag breaking hammer and a crushing method. Background technique [0002] There is no mature technology for vanadium slag crushing in the world, especially the crushing of large vanadium slag with particle size ≥ 250mm is a major problem in the industry at present. Due to the instability of vanadium slag transportation time, cooling time and other factors, the state of the vanadium slag poured out from the vanadium slag tank is different. According to the statistics of the actual situation, the vanadium slag poured out from the slag tank is mainly in the form of red molten fine particles, which are coated with solid shells; in some rare cases, the whole vanadium slag will agglomerate. The shell temperature of the freshly poured vanadium slag is about 300°C, and the temperature of the red molten fine particles inside is abo...

Problems solved by technology

Due to the different forms of vanadium slag and the high temperature, it is difficult to crush directly through the crusher

[0003] The main method now is to crush slag by dropping hammer (slab) or hydraulic crushing. It is necessary to manually operate lifting equipment to lift the falling hammer (slab) to crush large pieces of vanadium slag, or manually operate hydraulic crushing. The machine (internal combustion engine) is broken one by one, the workload is heavy, and the labor intensity of the workers is high

Moreover, a large amount of dust and noise are generated during the process, which does not meet the requirements of industrial hygiene and environmental protection.

Before the vanadium slag enters the primary jaw crusher, it needs to be crushed, water-cooled, stockpiled, and transported in an open space, which is inefficient and takes up a lot of space

Repeated smashing of slag leads to frequent equipment failures, high production costs and many other disadvantages
