Abstract

The utility model relates to a chain grate which can be conveniently dismounted. The utility model belongs to a grate for boiler. Two ends of each set of fire bars made up with five sheets are inserted with middle splints and form a grate with necessary length, and each middle splint is connected through a traverse bar. Among the middle splints of the grate, one splint is with double groove, and the rest are the middle splints with one sided groove. The fire bar in the front end of each group of fire bars of the grate is provided with an arch handle. The structure above is new and unique, which solves the problems that the grate is easy to fall off, thus making the grate firmer, and preventing that the fire bars are blocked with each other or break. Moreover, the utility model reduces greatly failure rate of the grate, therefore ensures normal running of the boiler.

Description

The traveling-grate stoker of easy accessibility

Technical field

The utility model belongs to the fire grate that boiler uses.

Background technology

Traveling-grate stoker is that Industrial Boiler and small power generation boiler adopt maximum a kind of fire grates, louver stoker is chain fire-gate common structure, by chain, sleeve pipe, wear bar, bearing pin, clamping plate and fire bars and form, have advantages such as ashpit losses is few, easy to maintenance, the operation troubles rate is lower.Under the situation that louver stoker is coal-fired in the high heating of burning, ventilation is not good again, fire grate is happened occasionally by scaling loss, distortion and dropping situations, the maintenance personal must in time change fire grate segment, during replacing that fire grate is out of service, with forcing to push certain distance aside between fire grate two chains, remove and install new fire bars with little crowbar.Because the free gap is less between two chains, maintenance personal's operant level does not wait in addition, and the dismounting that makes fire bars is difficulty relatively, often makes chain produce distortion even damages, thereby make fire grate generation sideslip, bite, fall fault such as chain, causes boiler breakdowns.

Have at present and a kind of above-mentioned louver stoker is carried out improved products, though the fire bars easy accessibility because of clamping plate two sideband mouths, makes fire bars come off easily, and in the fire bars of every group of clamping plate foremost, the fire bars of rearmost end has arc ears or side handles of a utensil, occurs card fire bars or phenomenon that Duan fire bars easily.

Summary of the invention

The utility model provides a kind of traveling-grate stoker of easy accessibility, with solve present fire grate exist card article, Duan not fire bars and the caducous problem of fire bars.The technical solution adopted in the utility model is: five one group fire bars two ends and middle splint are pegged graft and are formed the fire grate that needs length, each middle splint connects by wearing bar, be the double groove middle splint except that clamping plate in the middle splint of this fire grate, remaining middle splint is a single face groove middle splint, and foremost fire bars has arc ears or side handles of a utensil in the fire bars of every group of clamping plate.

The utility model advantage is novel structure, and it is the double groove structure that five one group fire grate has only a middle splint, and all the other are single face groove structure, have solved the problem that fire grate comes off easily, make fire grate more firm; In the fire bars of every group of clamping plate, have only fire bars lower sideband ear foremost, prevented between fire bars mutually card article or Duan fire bars.Significantly reduce the fault rate of fire grate, thereby guaranteed the normal operation of boiler.

The specific embodiment

Referring to Fig. 1, Fig. 8, five one group fire bars 1 two ends and middle splint 2 are pegged graft and are formed the fire grate that needs length, each middle splint connects by wearing bar 3, be the double groove middle splint 21 except that clamping plate in the middle splint of this fire grate, remaining middle splint is a single face groove middle splint 22, and foremost fire bars has arc ears or side handles of a utensil 4 in the fire bars of every group of clamping plate.

Referring to Fig. 2, Fig. 3, Fig. 4, wherein the structure of double groove middle splint 21 is that the axis hole top of clamping plate both sides respectively has rectangular channel 23.

Referring to Fig. 5, Fig. 6, Fig. 7, wherein the structure of single face groove middle splint 22 is that the axis hole top of clamping plate one side has rectangular channel 24.

Claims

1, a kind of traveling-grate stoker of easy accessibility, five one group fire bars two ends and middle splint are pegged graft and are formed the fire grate that needs length, each middle splint connects by wearing bar, it is characterized in that: be the double groove middle splint except that clamping plate in the middle splint of this fire grate, remaining middle splint is a single face groove middle splint, and foremost fire bars has arc ears or side handles of a utensil in the fire bars of every group of clamping plate.
