Abstract
The utility model relates to a coal sampling device with variable frequency regulation of a division ratio, which comprises a control calculator (1), a hopper scale (2), a crusher (3), a division device (4), and a frequency converter (5). A coal sample is weighed by the hopper scale (2); the obtained data are transferred to the control calculator (1) through a data line; the control calculator (1) compares a calculated actually-required division ratio with a set division ratio; the control calculator (1) outputs a signal to the frequency converter (5); the frequency converter (5) regulates the coal sampling amount by regulating the rotating speed of the division device (4).
Description
Technical field
The utility model patent relates to the coal samling device, specifically a kind of coal samling device of variable frequency adjustment division ratio.
Background technology
In recent years, going deep into gradually of coal market, rising steadily of coal price, what coal supply side adopted large dolly comes the coal mode, cart dress colm, and dolly installs coal, the modes of present stage many employings artificial sample, this causes the complicacy of sampling work and not representative, and has the coal samling device of automatic control division ratio, can well solve this class problem.
Summary of the invention
The purpose of the utility model patent is to provide a kind of coal samling device of variable frequency adjustment division ratio.
The coal samling device of a kind of variable frequency adjustment division ratio of the present utility model includes and controls counter (1), bunker scale (2), destroyer (3), reduction device (4), frequency converter (5).Bunker scale (2) carries out weighing to coal sample, the data obtained is transferred to by data line controls counter (1), control counter (1) according to calculating actual required division ratio, the required division ratio of reality and setting division ratio are compared, to frequency converter (5) output signal, frequency converter (5) is regulated the coal samling amount by the rotating speed size of regulating reduction device (4).
The utility model patent compared with prior art has the following advantages: automaticity is high, strong adaptability.
Description of drawings
