Abstract

The invention discloses a device for adjusting thickness of a coal seam of a boiler. The technical scheme includes that a stainless steel plate 1.5mm in thickness is cut into a fish-tail-shaped formwork 250mm in width and 100mm in length, is hammered in a circle to be semi-arc-shaped by a hammer, the radius a semi-arc at two symmetric diagonal edges is 5mm, straight edges of perpendicular symmetric shafts form a symmetric triangle, the axes of the symmetric shafts are hammered into a projection about 16mm in height, a stainless round steel rod 12mm in diameter is welded at tips of the symmetric shafts and is in length measured according to a schematic diagram annotated by an attached map, the other end of the stainless round steel rod is twisted to be provided with a thread, and a handle is made of a nut and a screw. Holes in a row are respectively drilled at a 200mm position of the head of the stainless round steel rod at intervals each 15mm, the hole diameter is 3.5mm, cross bolts 3mm in diameter is inserted into the holes and can be made by galvanized iron wires. The device for adjusting thickness of the coal seam of the boiler is reasonable in structure, convenient to manufacture, simple to adjust, easy to mount and good in effect.

Description

A kind of device of adjustable steam coal layer thickness

Technical field

Patent of the present invention relates to a kind of device that is used in boiler adjusted coal seam thickness, it is made with corrosion resistant plate, be contained in the boiler coal bunker, be close to grate surface, be used for regulating the steam coal layer thickness, make to enter the coal seam attenuate that can not fully burn clean in the boiler furnace, it is clean to allow coal all burn, and is sparing in the use of coal.

Background technology

Raw coal is entering in the boiler furnace fire burns, because the humidity of coal is irregular or the distribution of particle sizes inequality of coal, also might be that reason such as boiler uneven air all might cause coal burning unclean, goes out to reveal black slag phenomenon, causes the waste of coal.In order to allow coal combustion clean, the measure of taking usually is the attenuate coal seam thickness, can cause boiler output to descend because coal input quantity reduces like this, and imperfect combustion often shows as to have along the fire grate moving direction and contains flourishing cinder one by one.Contain flourishing cinder and not only cause the coal waste, more seriously it also burns out the fire grate mop easily, can cause the boiler grate fault.So production unit is all thinking that the whole bag of tricks solves this problem, I am engaged in boiler work for many years, by test of many times and improvement, the unburnt device of coal on a kind of solution traveling-grate stoker is now disclosed, the characteristics of its maximum are can not influence the boiler normal combustion, attenuate coal seam thickness not, it is quite convenient to operate.

Summary of the invention

The present invention discloses a kind of device of adjustable steam coal layer thickness, and scheme thes contents are as follows: selecting thickness for use is the corrosion resistant plate of 1.5mm, is cut into picture like the template of fish tail bar shape, width 250mm, length 100mm.Circle limit with iron hammer rapping plate becomes semi arch again, and two symmetrical hypotenuse place radiuses are at 5mm, and the straight flange of vertical axis of symmetry becomes symmetrical triangle, the about 16mm of symmetry axis axis place knock height of projection.At the stainless garden steel of a thick 12mm of symmetry axis sharp corner weldering, the schematic diagram that length is annotated by the accompanying drawing table is measured, and is twisted into screw thread at another head of stainless garden steel, makes a handle with nut and iron wire.Bore a round apart from the stainless garden 200mm of steel toe portion respectively by spacing 15mm again, the aperture is 3.5mm, will insert the horizontal latch of a thick 3mm in the hole, and horizontal latch can be made of galvanized wire.

Beneficial effect of the present invention is rational in infrastructure, and is easy to make, adjusts simply, installs easily, effective.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples.

Fig. 1 is a kind of device mounting structure schematic diagram of adjustable steam coal layer thickness.

The specific embodiment

Selecting thickness for use is the corrosion resistant plate of 1.5mm, is cut into picture like the template of fish tail bar shape, width 250mm, length 100mm with the scissors car.Beat over along a circle limit of template with iron hammer again, knock semicircle arcuation, at 5mm, the straight flange of vertical axis of symmetry becomes symmetrical triangle at two symmetrical hypotenuse place semi arch radiuses, and the shape of knock also can be out of shape by high temperature like this.With the about 16mm of symmetry axis axis place knock height of projection, two symmetric graphs of the fish tail of making like this bar shape template form two inclined-planes, and the effect on these two inclined-planes is to allow coal direction dispersion to the left and right.At the stainless garden steel of the thick 12mm of symmetry axis sharp corner weldering of fish tail bar shape template, the schematic diagram that length is annotated by the accompanying drawing table is measured, as long as it is just passable to guarantee that the coal seam thickness adjusting device can reach the coal gate middle part.Another head at stainless garden steel is twisted into screw thread, and reach is welded in an iron wire with a nut and makes on the circle at 10mm, nut is screwed on the screw thread of stainless garden steel toe portion, as the handle of coal seam thickness adjusting device again.Bore a round apart from the stainless garden 200mm of steel toe portion respectively by spacing 15mm again, the aperture is 3.5mm, will insert the horizontal latch of a thick 3mm in the hole.Horizontal latch can be made of galvanized wire, and the effect of horizontal latch is to fix stainless garden steel, does not allow the coal seam thickness adjuster enter in the burner hearth with raw coal.The coal seam thickness adjuster is separately fixed on the baffle-panels of boiler stokehold, whole coal seam thickness adjusting device is placed on the interior grate surface of coal bunker, and the back side is fixed on the baffle plate of stokehold with horizontal latch up, adorn severally, the position of dress still will often go out flourishing relative position according to the boiler cinder and install.When the coal seam thickness of needs attenuate somewhere, as long as the coal seam thickness adjusting device is protruded in the coal gate, allow it reduce the coal seam thickness that enters boiler, that stretches gets over into, and what subtract is more thin, and outwards stretching just can increase coal seam thickness.

Claims
