Embodiment
A kind of multiple spot coal fines sampling apparatus is the utility model is related to, including gos deep into the probe tube of pulverized coal channel, the sampling
The front end of pipe is provided with sample tap at two, and the part for going deep into pulverized coal channel of probe tube is additionally provided with three groups a little rotated around probe tube
Sampling is in charge of, and sampling is in charge of to be arranged in parallel with probe tube, samples the both ends being in charge of and is respectively equipped with two punishment pipe sample taps, sample tap
The direction come towards coal dust, can thus be divided into 8 points while carry out coal dust sampling.
Sampling is in charge of between rotation position and probe tube and is connected by swivel joint, and sampling is in charge of after rotary expansion and sampling
Pipe mutually coordinates 45 degree and is uniformly distributed.
The drive cavity of built-in probe tube is arranged in the prominent part of on the pulverized coal channel, the sampling is in charge of in the both sides of swivel joint
The both ends of steel wire rope are connected with, drive device is set inside the lateral direction of drive cavity, the drive device includes three groups of above-mentioned steel wires
Driving wheel, rotating shaft and the drive mechanisms of the circle of rope winding at least two, the girth of three groups of driving wheels and the steel wire rope of wound upon themselves connect
Sampling be in charge of the angle to be rotated and match.Three groups of drive paths between driving wheel and rotating shaft vary, driving wheel band
It is 45 degree, 90 degree and 135 degree that the steel wire rope of dynamic wound upon themselves, which pulls when rotating and samples the angle for being in charge of rotation,.
Probe tube sets the position of swivel joint to be provided with to side sampling to be in charge of prominent spacing preiection, and rotation is to requiring position
The sampling near probe tube put is in charge of to stop operating after raised hinder is limited.
Embodiment
Probe tube stretches out after drive cavity in a sealing fashion from the outside end side surface of drive cavity connects coal dust classifier, probe tube
The linear motion end of a straight line driving structure is fixed on after stretching drive cavity, the linear motion end of linear drives structure drives sampling
