Abstract
The utility model relates to a device for preventing a chain type boiler grate from deflecting, whcih is characterized in that hexagon socket head cap screws are used to fix two guiding positioning blocks on the inner sides of chain-grate side plates, at a position which is about 300mm forward from the center of a rear driven shaft, so that the device is formed. The utility model can thoroughly resolve the problem that a chain grate boiler is ''stuck'' and stopped due to the deflection of the grate during operation; high-strength steel is adopted, the wearing life is long after heat treatment, and moreover, the device can be replaced at any time according to the wear condition.
Description
One, technical field:
The utility model relates to a kind of chain type boiler fire grate centring device that prevents, belongs to the boiler combustion equipment category.
Two, background technology:
Now on the market with evaporation capacity at 1t/h～20t/h, operating pressure in the pressure steam boiler of 0.4MPa～2.5MPa and thermal power at 0.7MW～14MW, operating pressure bearing hot water boiler at 0.4MPa～1.6MPa, fire grate in the burner, all adopt rotary type traveling-grate stoker structure, in user's use, owing to the fire grate structure reason, the phenomenon that the fire grate sideslip often occurs, one side and chain fire-gate side plate of causing the traveling-grate stoker afterbody, closely contact produces the mill sassafras with traveling-grate stoker " stuck ", and urgent boiler main frame is out of service.Cause great economic loss to the user.
Three, Fa Ming content:
Goal of the invention of the present utility model provides a kind of chain type boiler fire grate centring device that prevents, thoroughly solves sideslip appears in the chain type boiler fire grate when boiler operatiopn problem.
To achieve the above object of the invention, the utility model adopts following technical scheme: a kind of chain type boiler fire grate centring device that prevents is characterized in that: it is with hexagon socket head cap screw (3) two guide-localization pieces (2) to be fixed on traveling-grate stoker side plate (1) inboard to constitute to the about 300mm in last segment distance place far from driven axle (4) center, back.
Advantage of the present utility model: can thoroughly solve chain grate boiler and be in operation, cause boiler complete machine stoppage in transit problem because of fire grate sideslip " stuck ".The utility model adopts high strength steel, after heat treatment friction durability long, and look abrasion condition and can change at any time.Result of use is splendid, and social benefit is huge.
Four, description of drawings:
Fig. 1 use of the present utility model and structural representation
Among the figure: 1-traveling-grate stoker side plate, 2-guide-localization piece, 3-hexagon socket head cap screw.
Five, the specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
A kind of chain type boiler fire grate centring device that prevents is characterized in that: it is with hexagon socket head cap screw (3) two guide-localization pieces (2) to be fixed on traveling-grate stoker side plate (1) inboard to constitute to the about 300mm of last segment distance place far from driven axle (4) center, back.
