Sample producing device

Abstract

The invention discloses a sample producing device which is used for producing a material sample and includes: a lifting belt used for lifting a material from exterior; a storage box connected to the lifting belt and used for storing the material; a crushing roller arranged below the storage box and used for crushing the material, a transporting board arranged below the crushing roller and used for transporting the crushed material; an interval sampling scratch plate arranged on the transporting board and used for obtaining samples from the transporting board at interval; a sample collecting and weighing device connected to the lower part of the interval sampling scratch plate and used for collecting and weighing the samples; and a bottle loading device arranged under the sample collecting and weighing device and used for loading a sample bottle with the sample. The sample producing device effectively ensures convenient operation and reduces production cost, and also reduces human factor influences and improves accuracy of a detection result.

Description

technical field [0001] The invention relates to the field of component detection, and more specifically relates to a sample preparation device. Background technique [0002] Coal is a solid combustible organic rock, which is transformed by biochemical action of plant remains, buried and then transformed by geological action. Coal is known as black gold and the food of industry. It has been one of the main energy sources used by the human world since the eighteenth century. The main elements contained in coal are carbon, hydrogen, oxygen, and nitrogen, accounting for more than 95%, and the remaining elements include sulfur, phosphorus, fluorine, chlorine, and arsenic. Carbon and hydrogen are elements that generate heat during coal combustion, and oxygen is a combustion-supporting element. When coal is burned, nitrogen does not generate heat, and is transformed into nitrogen oxides and ammonia at high temperatures, which are precipitated in a free state. Sulfur, phosphorus,...

AI Technical Summary

Problems solved by technology

In actual operation, due to the lack of special sample preparation devices, it is often necessary to occupy various supporting facilities during the coal sample preparation process, such as coal conveying devices, coal crushing devices, coal sampling devices, etc., so the operation is very inconvenient and The production cost is very high; in addition, the existing sample preparation process mainly relies on manual selection of samples, and the factors of human interference are relatively large, which seriously affects the accuracy of the test results
