Description
Technical field
The fixing of fire grate segment that the utility model belongs to the incineration furnace grate system of solid waste incineration processing reaches adjusting device, particularly relates to the fixing and adjusting device of fire grate segment afterbody of the incineration furnace grate system of domestic waste.
Background technology
The vitals of incinerator is the incineration furnace grate system.The incineration furnace grate system is responsible for the interior rubbish of stove and transports, and improves rubbish and Air mixing and disturbance degree simultaneously, improves efficiency of combustion.
Existing polytype now incinerator heat-extraction system comes out especially so-called reciprocating type incinerator heat-extraction system.The fire grate segment of reciprocal grate form overlaps regularly as roof sheet tile, forms the supporter of incineration firing.Fire grate segment that can seesaw and fixed grate film interleaved, its relative motion cause that rubbish is to forward and backward motion.On reciprocating type promotion fire grate, waste layer is by continuous upset and stirring consumingly, makes waste layer loose repeatedly and rearrange.
Through the development of last 100 years, the following version of the fixing employing usually of fire grate segment afterbody: fire grate segment is fixed on the crossbeam by the circular arc draw-in groove of its afterbody, and both form the hinge connection, and fire grate segment can freely rotate in fore-and-aft plane around this hinge.Under rubbish and self gravitation effect, the head bottom surface of upper grate sheet and the end face of lower floor's fire grate segment fit tightly.Cause this fire grate drive system running resistance to strengthen, cause the excessive wear of fire grate segment head, end face simultaneously in the contact position.In addition when the fire grate segment head is blocked in foreign matter and slagging scorification, the slit that can increase upper and lower layer grate sheet contact-making surface is caused lime-ash to enter air compartment easily and is leaked out.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of fixing and adjusting device of fire grate segment afterbody that can adjust upper and lower layer grate sheet superposed surfaces gap.
The technical solution of the utility model is as follows: the fixing and adjusting device of a kind of fire grate segment afterbody, comprise pull bar and the crossbeam that is installed on the pull bar, its key is: described beam surface upper is provided with pin, this pin inserts in the fire grate segment afterbody fixed card slot, it between described pin and the draw-in groove plane contact, between described crossbeam and pull bar, be inserted with wedge, this wedge middle part has stopper slot, and the stopper slot that bolt passes in the wedge from top to bottom is fixed together described crossbeam, wedge and pull bar three; Described wedge rear end is connected with screw mandrel, and this screw mandrel is fixed on the described pull bar by bearing, and this wedge that loosers a bolt can move forward and backward within the specific limits.Described wedge is low early and high after ladder structure of right angle, and the end that this wedge is high stretches out outside the described crossbeam, connects screw mandrel at this end.
Adopt such scheme, looser a bolt, by adjusting screw mandrel, wedge is moved forward and backward, thereby lifting or reduction fire grate segment rear portion height, and then the superimposed gap between the adjusting upper and lower layer grate sheet, allowing between the upper and lower layer grate sheet is not to be close to fully, reduce fire grate drive system running resistance, prevent the excessive wear between the end face of the head bottom surface of upper grate sheet and lower floor's fire grate segment; The adjusting device at fire grate segment angle of inclination, can prevent appearance slit between the adjacent fire grate segment in nature, because between pin and the draw-in groove is plane contact, the fire grate segment head can not rotate around pin, thereby prevent the slit that occurs between the upper and lower layer grate sheet, foreign matter and slagging scorification are difficult for blocking the fire grate segment head and increase upper and lower layer grate sheet slit, cause lime-ash to enter air compartment and leak out; Along the fire grate system lateral arrangement several fixing and adjusting devices of fire grate segment afterbody independently, can eliminate crossbeam since mismachining tolerance and be heated inhomogeneous, the position of the crossbeam upper fire-grating sheet that causes, height inconsistent; Adopt the concavity draw-in groove, be convenient to the Fast Installation and the dismounting of fire grate segment; The size of concavity draw-in groove has been considered the influence that fire grate segment expands with heat and contract with cold fully, guarantees that fire grate segment is fixing reliable.
Beneficial effect: can lifting, reduce single fire grate segment rear portion height, reach and regulate the gap between the fire grate segment superposed surfaces up and down, with reduce fire grate drive system running resistance, the contact position excessive wear of fire grate segment head prevents to be superimposed; Can eliminate crossbeam since mismachining tolerance and be heated inhomogeneous, the position of the crossbeam upper fire-grating sheet that causes, the height inconsistent; Avoid lime-ash to enter air compartment and leak out.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, fixing and the adjusting device of the utility model fire grate segment afterbody, form by pull bar 1 and crossbeam 2 grades that are installed on the pull bar 1, wherein said crossbeam 2 upper surfaces are provided with pin 4, this pin 4 inserts in the fire grate segment 6 afterbody fixed card slots, be plane contact between described pin 4 and the draw-in groove, between described crossbeam 2 and pull bar 1, be inserted with wedge 3, these wedge 3 middle parts have stopper slot 3a, and the stopper slot 3a that bolt passes in the wedge 3 from top to bottom is fixed together described crossbeam 2, wedge 3 and pull bar 1 three; Crossbeam 2 upper surfaces are the plane, with the inclined-plane of wedge 3 upper surface contact-making surfaces for matching with wedge 3 upper surfaces; Described wedge 3 rear ends are connected with screw mandrel 5, and this screw mandrel 5 is fixed on the described pull bar 1 by bearing 1a, and are by bolt and this screw mandrel 5 that wedge 3 is fixing.
Can further find out from Fig. 1, the fire grate segment up and down 6 that is superimposed together, the front portion of lastblock rides over the top of next piece, and afterbody wedge 3 fixing and adjusting device is low early and high after ladder structure of right angle, these wedge 3 high ends stretch out outside the described crossbeam 2, connect screw mandrel 5 at this end.
When needing to reduce fire grate segment 6 rearward height, looser a bolt, regulate screw mandrel 5 wedge 3 is moved backward, tight a bolt again after putting in place, crossbeam 2, wedge 3, pull bar 1 are fixed together; When needing lifting fire grate segment 6 rearward height, looser a bolt, regulate screw mandrel 5 wedge 3 is moved forward, tight a bolt after putting in place, crossbeam 2, wedge 3, pull bar 1 are fixed together.
