Abstract

The invention discloses a full-automatic online pulverized coal sampling device and a sampling method thereof. The full-automatic online pulverized coal sampling device comprises a bracket mounted ona pulverized coal pipeline, a sampling box mounted on the bracket, an electrical control box connected to the sampling box, and a sampling bottle mounted below the sampling box, wherein fixed plates are respectively mounted at two ends of the sampling box, a guide pillar is fixedly connected between the two fixed plates, a movable plate is sleeved on the guide pillar, and the movable plate can slide along the guide pillar; a sampling gun, a negative pressure generator, a lead screw and a cyclone separator are further installed in the sampling box, one end of the lead screw penetrates through the movable plate and then is connected with a stepping motor, and a control unit, a differential pressure transmitter, a power source, an electromagnetic valve, a blowback valve and an air adjusting valve are installed in the control box. According to the full-automatic pulverized coal online sampling device and the sampling method thereof, large workload caused by manual sampling is avoided, constant-speed sampling is achieved through the differential pressure transmitter and the negative pressure generator, and representativeness of taken samples is improved.

Description

【Technical field】 [0001] The invention relates to the field of automation equipment, in particular to a fully automatic pulverized coal online sampling device and a sampling method thereof. 【Background technique】 [0002] Coal fineness is an important parameter for boiler combustion adjustment. It directly affects the safe and economical operation of the boiler. Therefore, it is necessary to measure the coal fineness in time and accurately according to the change of boiler combustion coal quality, so as to be able to control, Adjust boiler combustion. Realize the best operation mode of boiler. The intermediate storage type pulverizing system has a pulverized coal bunker to store pulverized coal, so it is easy to take out pulverized coal at the pulverized pipe, and the representation is good. Since there is no pulverized coal bin in the direct blowing pulverizing system, in order to determine the fineness of pulverized coal, it is generally only possible to extract pulverize...
