Description
Invention field
The utility model relates to a kind of fire grate that is used for the stratiform coal furnace, particularly a kind of flute profile roller fire grate that is used for the stratiform coal furnace.
Background technology
Fire grate is one of capital equipment of stratiform coal furnace.Stoker fired grate commonly used has chain-type stove, reciprocating fire grate and convertible fire grate, and it is big that these fire grate ubiquities the driving energy consumption, and the fire grate cooling effect is not good, and the fire grate motion is little to the coal seam disturbance, and the coal bed ventilation poor effect is unfavorable for burning of coal; And its structure more complicated, the easy corrupted of fire grate parts, the parts of corrupted are difficult for changing the operation maintenance difficulty.
In order to reduce the driving energy consumption, improve the fire grate cooling effect, the someone adopts the fire grate of roller formula structure, roller in this fire grate is the hollow roll shaft, and the axial wall of roll shaft is provided with air vent, hollow roll shaft inner ventilation, wind is admitted to the coal seam by air vent, reaches to make coal bed ventilation, clean-burning purpose.Yet this roller formula fire grate of being made up of the hollow roll shaft exists complex structure equally, to the coal seam disturbance defective such as little and operation maintenance inconvenience, so applied so far.
Summary of the invention
The purpose of this utility model is, overcomes many defectives that above-mentioned fire grate exists, and provides a kind of driving energy consumption little, and cooling effect and coal bed ventilation effect are all good, and the fire grate parts are not fragile, and the flute profile roller fire grate that is used for the stratiform coal furnace simple in structure.
The technical solution of the utility model is as follows:
The flute profile roller fire grate that is used for the stratiform coal furnace that the utility model provides, it is characterized in that, this flute profile roller fire grate comprises and parallelly is placed at least 3 wheel shafts 2 on a plane and is nested in flute profile fire grate roller 1 on the wheel shaft 2 respectively, this flute profile fire grate roller 1 is made up of the gear 41 that one group of parallel longitudinal fuses at interval, and 41 of adjacent gears are provided with teeth groove 42; Gear 41 dislocation on the adjacent flute profile fire grate roller 1 are placed; A bearing shell 3 is installed at the two ends of every wheel shaft 2 respectively, one ratchet 5 wherein is installed on the wheel shaft 2 in an end bearing shell 3 outsides, be connected on the push rod 15 with wheel shaft 2 vertical placements with the other end of the ratchet 10 of each ratchet 5 engagements, crank rockers 14 that are connected with driving wheel 12 off-centre are connected by a linking arm 151 with this push rod 15; Described flute profile fire grate roller 1 rotation direction is identical; A part of flute profile fire grate roller in the perhaps described flute profile fire grate roller 1 and another part flute profile fire grate roller direction of rotation.
During use, this bearing shell 3 at the two ends of flute profile fire grate roller 1 by being enclosed within wheel shaft 2 that is used for the flute profile roller fire grate of stratiform coal furnace is fixed on metal frame under the burner hearth, be furnished with corresponding screw hole on bearing shell 3 and the metal frame, utilize bolt that bearing shell 3 and metal frame are fixed together.When flute profile fire grate roller 1 is installed, in the draw-in groove on the metal frame that only needs each flute profile fire grate roller 1 is aimed under the burner hearth, screw bolt, can finish its installation quickly and easily, during dismounting, only need to screw out bolt, flute profile fire grate roller 1 just falls automatically, so this fire grate is installed, maintenance is convenient, can overhaul single flute profile fire grate roller 1, not need blowing out.
So, the utlity model has that to drive energy consumption little, cooling effect and coal bed ventilation are effective, the fire grate parts are not fragile, the easy single replacing of the fire grate of damage, change simple to operation, and advantages of simple structure and simple.

The specific embodiment
By Fig. 1 and Fig. 2 as can be known, the flute profile roller fire grate that is used for the stratiform coal furnace that the utility model provides, it is characterized in that, this flute profile roller fire grate comprises and parallelly is placed at least 3 wheel shafts 2 on a plane and is nested in flute profile fire grate roller 1 on the wheel shaft 2 respectively, this flute profile fire grate roller 1 is made up of the gear 41 that one group of parallel longitudinal fuses at interval, and 41 of adjacent gears are provided with teeth groove 42; Gear 41 dislocation on the adjacent flute profile fire grate roller 1 are placed; A bearing shell 3 is installed at the two ends of every wheel shaft 2 respectively, one ratchet 5 wherein is installed on the wheel shaft 2 in an end bearing shell 3 outsides, be connected on the push rod 15 with wheel shaft 2 vertical placements with the other end of the ratchet 10 of each ratchet 5 engagements, crank rockers 14 that are connected with driving wheel 12 off-centre are connected by a linking arm 151 with this push rod 15; The engagement direction of described ratchet 5 and ratchet 10 is identical; The a part of ratchet 5 in the described ratchet 5 and the engagement direction of ratchet 10 are opposite with the engagement direction of another part ratchet 5 and ratchet 10.
Accompanying drawing 3A is the schematic diagram that ratchet 5 is meshed with ratchet 10 and ratchet 5 works are rotated counterclockwise; Accompanying drawing 3B is the schematic diagram that ratchet 5 is meshed with ratchet 10 and ratchet 5 works are clockwise rotated;
Accompanying drawing 5 is for having the flute profile roller fire grate that is used for the stratiform coal furnace of two-way flute profile fire grate roller 1, one group flute profile fire grate roller 1 clockwise rotates, another group flute profile fire grate roller 1 rotates counterclockwise, the power of motor input rotates the driving wheel 12 of crank rocker 14, drive crank rocker 14 is done reciprocating motion to the left and right, crank rocker 14 drives push rod 15 again and does to the left and right reciprocating motion, thereby drives ratchet mechanism (comprising ratchet 5 and ratchet 10) acting; When push rod 15 during to left movement, during the right left movement of left side ratchet machine, the left side ratchet mechanism rotates right side one group of flute profile fire grate roller 1, and left side one group of flute profile fire grate roller 1 does not rotate; So just, can reach the purpose of fire grate to both sides discharging lime-ash; If do not need to both sides discharging slag, then, the flute profile roller fire grate that only need have unidirectional flute profile fire grate roller gets final product, as shown in Figure 4.
