Description

A kind of environment protection type energy saving boiler

Technical field

The utility model relates to a kind of coal-burning boiler, be furtherly a kind of be the environment protection type energy saving boiler of fuel with the moulded coal, be to the improvement of existing coal-burning boiler structure, be suitable for when bathing, heating, using.

Background technology

At present, traditional coal-burning boiler of selling on the market is a fuel with civilian diffusing coal all generally, exists the shortcoming of insufficient, the easy over-emitting black exhaust of burning, contaminated environment.For this reason, also the someone develops a kind of to burn the boiler of moulded coal: be about to old-fashioned fixed fire grate hot-water boiler and transform a little, open a coal falling hole at the rear portion of fire grate, during use, promote moulded coal backward from fire door, it is moved along fixed fire grate with a propulsion plant, last row is pushed the natural and graceful hole ash entrance chamber that falls with the moulded coal of after-flame, its shortcoming is when promoting moulded coal, because of frictional resistance between coal and fire grate is bigger, very easily squeezes moulded coal broken.Given this, No. 90200611.8, China's utility model patent, provided a kind of " having the combination separate type moving grate Honeycomb briquet hot-water boiler that can advance ", way is: fix two horizontal slideways on the sidewall of burner hearth, can be slided along this slideway in the two ends of separate type fire grate, leave distance between the tail end of slideway and the rear wall of burner hearth, make last piece fire grate break away from the moulded coal that can carry after-flame behind slideway ash entrance chamber that falls from here together greater than length before and after separate type fire grate.It is movable that its advantage is that the fire grate with above-mentioned molded coal boiler changes into, makes moulded coal when row advances backward, advances together with fire grate, thereby moulded coal is not caused extruding, make it not broken when burning, its shortcoming: be that horizontal slideway is set on the sidewall of burner hearth, structure is complicated; Heavy separate type fire grate only slides at slideway by its two ends, advances in case a sideslip road wherein stops up or has distortion, coal pusher can't promote fire grate slightly.

The utility model content

The purpose of this utility model is to overcome the prior art above shortcomings, improve by research, provide a kind of environment protection type energy saving boiler, that this kind environment protection type energy saving boiler has is simple in structure, volume is little, floor space is few, characteristics such as easy to install, be up to state standards the requirement of GB13271 " emission standard of air pollutants for boilers " of its technical parameter.

Technical solution of the present utility model is: this environment protection type energy saving boiler that provides includes boiler body, push away device for coal and fire grate, its fire grate is a sub-assembly, by the fire grate basis, the portable fire grate of slideway and split is formed, be characterized in being arranged side by side the slideway that four cast iron stove beams make in burner hearth inside, one end of cast iron stove beam links to each other with the crossbeam of stove gate, the other end of cast iron stove beam links to each other with the crossbeam that is arranged on the burner hearth rear portion, be provided with the split packaged type fire grate of square structure above the cast iron stove beam, also be provided with an ash port at the rear portion of burner hearth, push away device for coal and adopt screw mandrel, the kind of drive of screw is set at the fire door front, push away a handwheel is arranged in the device for coal, handwheel is arranged on an end of screw mandrel, and the other end of screw mandrel is provided with coal-pushing plate.

Compared with prior art, the beneficial effects of the utility model are:

Simple in structure, need not lay complicated slideway;

Easy to operate, as long as the operator shakes the forward and back that handwheel can realize pushing away the coal frame, thereby contained moulded coal enters the burner hearth burning on the split packaged type fire grate of promotion square structure;

Reasonable in design, be the fire grate of the custom-designed square structure that matches with the square moulded coal, its percentage of air passage is big, helps the abundant burning of fuel, and the resistance of Tong Fenging is little simultaneously, can adopt the air supply mode of air blast;

Compliance with environmental protection requirements has reached the requirement of the class one zone of regulation in the standard GB 13271 " emission standard of air pollutants for boilers ".
