Abstract

The utility model relates to an improved grate for hand-fired boilers, which is composed of a grizzly bar, a cushion block, connecting bolts, an n-shaped positioning plate, distance adjusting screw bolts, etc. The utility model can obtain the separation distance between different grid gaps and between an upper layer grate and a lower layer grate according to requirements, and the grid areas of the upper layer grate and the lower layer grate and the gap areas are mutually stagger and overlapped for being suitable for burning different coal.

Description

Combined variable double staggered grate

The utility model is a kind of improved hand-fired boiler grate.

No matter existing hand-fired boiler grate is bilayer or individual layer, the grizzly bar number, spacing between grid gap and the two-layer grate is definite value, can not adapt to different coals, often, influence applying of hand-fired boiler because the difference of various places coal causes fuel combustion operating mode quality not wait.

The purpose of this utility model is for overcoming the variable double-layer staggered grate of a kind of combined shaped that above-mentioned difficulties designs, spacing between the grizzly bar number of every layer of grate and grid gap and the two-layer grate all can be selected assembling on demand, make hand-fired boiler burn different coals and all can obtain satisfied following grey condition, can guarantee rational coal seam thickness, thereby reach stable combustion conditions.

The task that the utility model proposed is realized by following measure: every layer of grate of double-layer staggered grate formed by grizzly bar, cushion block, connecting bolt, Contraband type location-plate, every grizzly bar two ends and cushion block all are drilled with centre bore, folder is with cushion block between the some grizzly bars, the centre bore that connecting bolt passes grizzly bar two ends and cushion block is linked to be integral body with grizzly bar and cushion block and sticks in the Contraband type location-plate, spacing between the upper and lower two-layer grate obtains with setting-up screw or Xiao, post class device, and the grid zone of upper and lower two-layer grate and interstitial area intermesh overlapping.

The type variable combined double-layer intercrossed grate bar that the utility model proposed is simple in structure, easy to use, for the brown coal inferior that directly burn have solved time grey problem, so be suitable for the different coal of burning.

Concrete structure of the present utility model is provided by following examples and accompanying drawing:

Fig. 1 is the structural representation of every layer of grate of type variable combined double-layer intercrossed grate bar of proposing of the utility model.

Fig. 2 is the main pseudosection of the type variable combined double-layer intercrossed grate bar that proposes of the utility model.

From Fig. 1 and Fig. 2, can find out, type variable combined double-layer intercrossed grate bar comprises up and down two-layer grate (A) and (B), every layer of grate is by grizzly bar (1), cushion block (3), connecting bolt (4), Contraband type location-plate compositions such as (2), grizzly bar (1) is single foundry goods, all be drilled with centre bore (6) on the two ends of every grizzly bar (1) and the cushion block (3), press from both sides cushion block (3) between the some grizzly bars (1) on demand to form the interstitial area of different size with different-thickness, the centre bore (6) that connecting bolt (4) passes grizzly bar (1) and cushion block (3) is linked to be integral body with it and sticks in the Contraband type location-plate (2), on, be overlapping between following two-layer grate (A) and interstitial area (B) and grid zone are mutual, the spacing between them is adjusted with setting-up screw (5) or Xiao Zhu class formation (not drawing among the figure).

Claims

1, the grate of hand-fired boiler (A) and (B) be made up of grizzly bar (1) is characterized in that:

A, grizzly bar (1) form for single casting, accompany cushion block (3) between the some grizzly bars (1) to form the interstitial area of different size, grizzly bar (1) two ends and cushion block (3) all are drilled with centre bore (6), and connecting bolt (4) passes centre bore (6) and grizzly bar (1), cushion block (3) are tightened to integral body stick into Contraband type locating piece (2) and be combined into grate (A) or (B);

B, upper and lower two-layer grate (A) and (B) between spacing adjust with setting-up screw (5) or Xiao, post class device;

C, upper and lower two-layer grate (A) and (B) between grid zone and interstitial area intermesh overlapping.
