Abstract
The invention relates to the field of molded coal production, in particular to an environment-friendly molded coal. The molded coal is characterized by being formed by mixing and pressing the raw materials based on the proportion: 5-20% of coal gangue, 70-90% of mine run coal, 4-10% of bonding agent and 0.1-3% of dryer. The molded coal is provided with a through hole in the middle part, and fully utilizes the coal gangue which is the waste material, so as to change waste into valuable. Furthermore, the environment-friendly molded coal is high in combustion rate and sufficient in burning, reduces fine dust, protects the environment, can be rapidly molded and solidified, is widely applied to coal gangue power stations, and can substitute powdered coal.
Description
Technical field
The present invention relates to the briquette production field, be specifically related to a kind of environment-friendly coal.
Background technology
Moulded coal is compared with raw coal has numerous advantages, sufficient combustion, and discharge of noxious gases is few, therefore moulded coal is widely used coal gangue serious environment pollution, the meeting that has spontaneous combustion, need handle its input expense, the processing cost height can cause secondary pollution, very big contaminate environment, the moulded coal of existing equipment production simultaneously is solid atresia, the oxygen supply deficiency, it is insufficient to burn, and dust is many, rate of combustion is low, also can produce obnoxious flavour, grievous injury people's health.
Summary of the invention
The purpose of this invention is to provide a kind of environment-friendly coal and production technique thereof, this moulded coal environmental protection, the dust of sufficient combustion, generation is few, can effectively utilize coal gangue.
A kind of environment-friendly coal, by coal gangue, raw coal, tackiness agent, siccative mixing compression moulding, each component proportions is as follows: coal gangue 5%～20%, raw coal 70%～90%, tackiness agent 4%～10%, siccative 0.1%～3%, described moulded coal middle part is provided with through hole.
Described tackiness agent is a sodium silicate solution.
Described siccative is an ammonia chloride, and moulded coal was solidified in several hours.
This kind moulded coal makes full use of the waste material coal gangue, turns waste into wealth, and the rate of combustion height, sufficient combustion reduces dust, the protection environment, and moulding is solidified soon, and this kind moulded coal is widely used in the coal gangue power station, can replace fine coal.
Embodiment
Embodiment 1
A kind of environment-friendly coal, by coal gangue, raw coal, tackiness agent, siccative mixing compression moulding, each component proportions is as follows: coal gangue 5%～20%, raw coal 70%～90%, tackiness agent 4%～10%, siccative 0.1%～3%, described moulded coal middle part is provided with through hole.Described tackiness agent is a sodium silicate solution.Described siccative is an ammonia chloride.
Embodiment 2
Take by weighing in proportion, coal gangue, raw coal, tackiness agent, siccative, 15.5 kilograms of coal gangues, 76 kilograms in raw coal, 8.2 kilograms in tackiness agent, 0.3 kilogram in siccative, described moulded coal middle part is provided with through hole.Powder is processed in raw coal and coal gangue fragmentation then, with tackiness agent, siccative uniform mixing, delivers in the feed bin, force reinforced through the screw feeding bar, enter between two squeegee rollers, be pressed into 2000 of heavily about 50 moulded coals that restrain by squeegee roller, moulded coal becomes shapes such as class sphere and elliposoidal.During work,, drive by squeegee roller because slotting tool rotates and to insert in each half groove, in half groove if be stained with the raw material of surplus, will have slotting tool insert broken, pull out.Because core bar bottom cooperates with breach, the core bar is positioned at the moulded coal middle part during compacting moulded coal, and during the demoulding, the core bar can move down a spacing with moulded coal, and from horizontal reset, stays through hole at moulded coal ball middle part, makes burning more abundant.
Embodiment 3
Take by weighing in proportion, coal gangue, raw coal, tackiness agent, siccative, 12 kilograms of coal gangues, 80 kilograms in raw coal, 7.8 kilograms in tackiness agent, 0.2 kilogram in siccative, described moulded coal middle part is provided with through hole.Powder is processed in raw coal and coal gangue fragmentation then, with tackiness agent, siccative uniform mixing, delivers in the feed bin, force reinforced through the screw feeding bar, enter between two squeegee rollers, be pressed into 1000 of heavily about 100 moulded coals that restrain by squeegee roller, moulded coal becomes shapes such as class sphere and elliposoidal.During work,, drive by squeegee roller because slotting tool rotates and to insert in each half groove, in half groove if be stained with the raw material of surplus, will have slotting tool insert broken, pull out.Because core bar bottom cooperates with breach, the core bar is positioned at the moulded coal middle part during compacting moulded coal, and during the demoulding, the core bar can move down a spacing with moulded coal, and from horizontal reset, stays through hole at moulded coal ball middle part, makes burning more abundant.
