Example Embodiment

[0048] The present invention will be further described below with reference to the drawings and embodiments: a two-story building is built on the belt corridor, the sampling machine 5 is installed on the first floor, and the sampling machine 5 is directly welded and installed on the foundation of the belt frame for transporting coke. The sampling machine 5 adopts a sub The sample volume is 15kg. After taking the material twice, it is lifted from the hoist 1 to the second floor of the corridor and enters the 1 / 8 reduction divider 2 for reduction, and the 1 / 8 coke enters the ring hammer crusher 3 for crushing to prepare water and work points In this way, 7 / 8 coke was dropped to the ground for screening composition and mechanical strength tests. The waste coke is returned to the coke transport belt from the second floor through the chute 4.

Abstract

This is an automatic method to collect the coke sample product. This collector is installed on the rotating conveyer belt to collect the coke sample. The collected sample transported to the second storey y promoter and enter into divider to reduce and divide them, after divided one of eighth sample enter into the closed circle hammer pattern breaker's vessel, the seven eighth of it is fall down to the ground to test them with mechanical strengthen. The wasted cokes go back return to the conveyer belt conveniently, and all these procession are automatic mechanical action. The device system use PLC to control the procession, to realize the whole course automatically act.

Description

technical field [0001] The invention relates to coke sampling and preparation technology, more specifically, the invention relates to a method for automatically collecting coke samples on a belt, and then automatically shrinking and crushing to prepare coke samples. technical background [0002] In large-scale iron and steel complexes, the metallurgical coke provided by the coking plant is an important raw material for ironmaking production, and plays the role of heat source, reducing agent and skeleton in blast furnace production, so its quality is an important indicator that affects the production operation of ironmaking blast furnaces, usually blast furnaces Production needs to test the chemical composition, physical properties and chemical properties of coke, and the sampling process is an important link in the process of coke quality inspection. The national standard GB1997-89 "Collecting and Preparation of Coke Samples" stipulates that coke samples should be taken from...
