The Coal Powder Sampler is designed for regular coal powder sampling in the primary coal powder pipeline of direct-blown coal pulverizing systems, specifically addressing the coal powder sampling issue in direct-blown coal pulverizing systems of thermal power plants. It is a customized, professional automated sampling equipment that relies on the equal circular ring area sampling method, ensuring representative samples. What are the features of the Coal Powder Sampler?

Product Features

1. Timed Sampling; This equipment is equipped with a microcomputer timer switch, which automatically takes samples within the set time frame, and then automatically shuts off to save energy. Operators only need to retrieve the sample in front of the sampler after the sampling time is set. For instance, if an operator sets the sampling time to 9 AM, with a 10-minute sampling duration (adjustable), they would simply pick up the sample at 9:10 AM. No further action is required, significantly reducing the operator's workload and improving sampling efficiency. The timer switch can be set for 16 timed events per day, allowing for 16 automatic sampling sessions.

2. Fixed-point sampling; the sampler is equipped with a programmable system that can set any sampling length. For instance, when the sampling length is set to 600mm, the sampler samples uniformly until 600mm away from the pipe wall, then automatically retracts into the protective tube, positioning itself outside the coal powder gas stream. This design minimizes wear and extends the lifespan.

3. Auto-Blowing; to prevent clogging of the sampling tube, the equipment performs an auto-blowing after each automatic sampling, with adjustable blowing time.

Unique Features

The sampling speed of the coal powder sampler is controlled by adjusting the pressure of compressed air. This ensures a more accurate, representative, and uniform coal powder fineness value.

Unique leak-proof interface, no leakage or powder overflow.

3. Non-clogging, non-corrosive stainless steel material manufacturing.

The sampling gun can be retracted into the protective tube, placing it outside the coal powder airflow, resulting in minimal wear and a longer lifespan.

1 person operation, 2-minute sampling, anytime, quick, and work easy.

This equipment features a unique design concept, effectively integrating the exhaust pipe with the sampling tube. Installation requires only the welding of a single connecting pipe.
