High-precision as-fired coal automatic rotary sampling equipment

Abstract

The invention discloses high-precision as-fired coal automatic rotary sampling equipment, and belongs to the technical field of as-fired coal sampling. The equipment comprises a feeding mechanism, a first motor, a telescopic cylinder, a sampling storage box, an electric telescopic rod, a second motor and a sampling head, a fixed plate is arranged above the feeding mechanism, and the telescopic cylinder is arranged in a fixed ring; a mounting cavity is formed in a telescopic part of the telescopic cylinder, an electric telescopic rod is mounted on the inner wall of the upper part of the mounting cavity, a second connecting rod is mounted below the electric telescopic rod, a second rotating shaft is mounted below a second motor, and a sampling head is mounted below the second rotating shaft;and a feeding opening is formed right in front of the feeding mechanism, and a sampling storage box is mounted below the first connecting pipe. The sampling head can be buffered through a buffer spring and a rubber buffer pad, and the situation that the sampling head touches the feeding mechanism in the downward moving process, and consequently a conveying belt on the feeding mechanism is damagedis prevented.

Description

technical field [0001] The invention belongs to the technical field of furnace coal sampling, in particular to a high-precision automatic rotary sampling device for furnace coal. Background technique [0002] The coal entering the furnace is the coal with full moisture entering the coal bunker of the boiler room. If the moisture in the coal entering the furnace is too large, the temperature of the flue can be lowered. If the temperature is too low, the shrinkage of the coke is not good and immature, and pushing the coke at this time will easily cause difficulty in pushing the coke, and even damage the furnace body. If the coke is to be matured on time, it is necessary to increase the amount of returned furnace gas burned, which increases the heat consumption and increases the consumption of returned furnace gas. Therefore, before the coal into the furnace is used, it is necessary to sample and detect the coal into the furnace. Most of the existing equipment used for the coa...

Problems solved by technology

Therefore, before the coal into the furnace is used, it is necessary to sample and detect the coal into the furnace. Most of the existing equipment used for the coal into the furnace has a relatively simple structure and low adjustment. When sampling, the sampling mechanism is easy to adjust The coal conveyor causes damage, and at the same time most of the existing sampling equipment only collects one sample, the detection error is large, the obtained data is not accurate enough, and the accuracy is not high
