Problems solved by technology

[0004] 2. The high ash content of coke powder type coke is due to the high ash content of coke powder
[0005] In addition, the existing technology still has some shortcomings, such as: the particle size of the coke pressed by the double-roller ball press is small, only 50g / piece, and the coke quenching in cold water causes waste of heat energy and water resources and pollution to the atmosphere, etc. still need to be improved

Embodiment Construction

[0013] The implementation mode of coke powder washing is: using a shaker sorter or a spiral sorter to wash coke powder, and then carry out water separation and initial drying to the washed coke powder after washing. The ash content of the washed fine coke powder is less than 12%, and the moisture content after initial drying is less than 5%. The specifications of the shaker separator or spiral separator can be designed and processed by entrusting mineral processing machinery factory or coal preparation machinery factory according to the output demand of the coke production plant.

[0014] The vibratory continuous molding method of coke is: in order to improve the thermal strength of the coke and realize high-efficiency continuous vibratory molding, the present invention specially made a "multi-station tube vibration molding machine" to realize "upper feeding, Vibration continuous molding method. The production process is explained with reference to the accompanying drawings: ...

Abstract

A kind of metallurgical coke under high pyrogenation status contains coke powder, modified asphalt, coal powder, and weak-adhesion-property or non-adhesion-property. It can reduce ash by using washing-selected coke powder and improve the interfacial treacliness by using coupling agent, this invention involves tubular inultistation oscillatory former, by which it can achieve continuous-form oscillatory method, that is, incharge on the top and discharge at the bottom. The invention not only improves the structural characteristic of coke but also raises the particle density for 50g to 200g. Additionally, this invention also adopts using coke powder to go out. And of course, it saves water and coal and remains unpolluted. In short, it advances and insures the caloric intensity of the coke by adopting the foregoing measures.

Description

Technical field [0001] The invention belongs to the technical field of coke, in particular to metallurgical coke with high thermal strength pressed by a vibratory continuous molding method. Background technique [0002] The evaluation method of the thermal strength of metallurgical coke follows the method of evaluating "reactivity" and "strength after reaction" in metallurgical coke. The higher the thermal strength of coke, the higher the post-reaction strength, and the lower the reactivity. Patents with application numbers 93222507, 94119416, 97109222, 97118873, 00134771, 00105251, etc., as well as "Coking Technology" published by Metallurgical Press in May 1994, proposed various coke technologies, among which metallurgical coke is better The technologies are anthracite briquette coke with pitch bonded anthracite and coke powder coke with pitch bonded coke powder. "Coking Technology" also explains the defects of these cokes: compared with metallurgical coke, the hot streng...
