Description

Technical Field

[0001] The invention relates to the technical field of sampling equipment, and in particular to a constant volume raw coal falling flow automatic sampling device. Background Art

[0002] Coal plays the role of both fuel and raw material in cement production. As a fuel, coal provides heat source for carbonate decomposition in the decomposition furnace and clinker burning in the rotary kiln. As a raw material, coal ash settles and mixes in the raw material to become part of the clinker. The calorific value and combustion characteristics, sulfur content, moisture, ash volatility, etc. of raw coal will affect the production of cement. my country is a country with a large coal production. The quality of coal varies greatly due to the uneven particle size distribution. Therefore, it is very important to take representative coal samples for testing when the coal enters the factory. At present, for coal sampling, samples are generally taken during the coal transportation process. Traditional coal sampling technology mainly takes samples of coal transported on the conveyor belt manually or automatically. The manual timed and fixed-point sampling method has poor representativeness of the sampled coal, and there are obvious errors in sampling by different personnel. The sampling staff has high labor intensity and certain safety risks.

[0003] For example, the announcement number CN104483160A disclosed a portable raw coal sampling device on April 1, 2015, including a sleeve, a sampling container and a connecting tube connecting the sleeve and the sampling container, the sleeve is provided with rope binding ports at both ends, the sampling container includes a tank body, a cover body and a blocking orifice plate arranged in the tank body, the blocking orifice plate tank body is divided into an air intake side and an exhaust side, an exhaust hole is arranged on the cover body on the exhaust side, and a pressure relief filter is arranged on the exhaust hole. The above-disclosed sampling device cannot perform convenient sampling when the raw coal falls, and has poor practicality. Summary of the invention

[0004] The purpose of the present invention is to provide a more convenient constant volume raw coal falling flow automatic sampling device.
