Belly expansion detecting device of crank slide block type multi-bin pipe mill and belly pre-expansion control method

Abstract

The invention discloses a belly expansion detecting device of a crank slide block type multi-bin pipe mill and a belly pre-expansion control method, and relates to the technical field of pipe mill detecting devices. The device is characterized in that the upper part of a detecting port (12) is sealed through a pipe mill top cover (2); a detecting device is mounted in the detecting port (12), and includes a hollow cylinder (5); a detecting head (4) for touching the internal of the pipe mill is mounted at the bottom end in the hollow cylinder (5); the upper end of the detecting head (4) is connected with a crank slide block component; one side of the top end of the crank slide block component is connected with a generator (8); and the detecting head (4) can drive the crank slide block component to move up and down. The device and the belly pre-expansion control method can detect a belly expansion state of the pipe mill, and can adjust the work of the pipe mill in real time to enable the pipe mill to work in a belly pre-expansion state at early stage of belly expansion.

Description

technical field [0001] A crank slider type multi-chamber tube mill expansion belly detection device and a pre-expansion belly control method relate to the tube mill detection device and the technical field. Background technique [0002] Tube mill is a very important fine grinding equipment in modern industry, widely used in the fields of grinding production in building materials, metallurgy, mineral processing, electric power and chemical industry. Large tube mills generally have multiple chambers, and their production capacity is very high. When the barrel of the mill is divided into two, three or four chambers of different lengths with partition plates, it is called a multi-chamber tube mill. The difference between the multi-chamber tube mill and the short tube mill is that its length is 2-7 times larger than the diameter, and the time for the material to pass through the tube mill is longer, the product fineness is uniform, and the crushing is relatively large. In the mu...

Problems solved by technology

The bulge of the tube mill is very harmful. The bulge not only causes the tube mill to lose (or reduce) the grinding effect on the ore, but also destroys the stable work of the grinding, and the treatment of the bulge will also cause the concentration of the ore to follow-up operations. and fineness fluctuations affect the normal operation of follow-up operations; in addition, severe belly swelling will cause tube mills, mine feeders, sand return boxes, bearings, gears, etc. to be damaged by impact loads

After the belly of the tube mill is expanded, it is generally treated by stopping the supply of mineral materials and increasing the supply of mineral water. When the phenomenon of belly swelling is serious, more complicated methods such as high-pressure water and manual unloading of the mill are used.

Belly swelling seriously affects the production efficiency of the tube mill
