Abstract

The utility model provides a novel coal loosening device which is installed on a fire grate below a furnace coal hopper and is used for loosening raw coal by utilizing the power generated when the chain fire grate moves together with the raw coal. The utility model adopts the technical scheme that: a scalene triangular iron (1) is hot rolled, and the length of the scalene triangular iron is controlled to the size that is one fire grate narrower than the width of the entire fire grates. Two right-angled edges of the hot-rolled scalene triangular iron are sealed by a steel plate A (2) with appropriate width, two ends of the hot-rolled scalene triangular iron are also sealed by a steel plate B (3) and a steel plate C (4) to form a three-dimensional triangle. A pipe A (5) and a pipe B (6) with identical length and with one end being provided with threads are utilized to be welded on the triangular surfaces of the long right-angled edge in parallel, a pipe C (7) and a pipe D (8) are utilized to be respectively connected with a left side wallboard and a right side wallboard in front of the fire grate through the threads, and a plurality of sections of flat iron (9) are welded below a soleplate of the coal loosening device at intervals to be used for abrasion resistance, so the abrasion of the fire grate on the coal loosening device can be reduced.

Description

Novel coal-loosening device

Technical field

The utility model patent relates to the equipment of using on a kind of boiler, and it is mounted on the fire grate of boiler coal bunker below, relies on the coal seam to move to become flexible the coal seam on grate chain, allows raw coal enter burner hearth and burns more complete, more thorough.

Background technology

All do not adorn coal-loosening device in present most of chain-grate boiler operation, raw coal enters burner hearth again from coal bunker will pass through coal gate earlier, and the coal gate role is that fixedly coal seam thickness is controlled coal input quantity.Raw coal runs into and just is subjected to coal gate behind the coal gate active force effect raw coal is compacted in the other direction, so air permeability is poor when entering the raw coal combustion of burner hearth, it is bad to burn, and is prone to black slag, causes the waste of raw coal.And it is bad to burn, and temperature is not high brings influence to production.

Summary of the invention

This patent proposes a kind of being contained on the fire grate of boiler coal bunker below, the power that moves together by traveling-grate stoker and raw coal becomes flexible the novel coal-loosening device device of raw coal, its scheme is: with a kind of hot rolling inequilateral angle iron (1), length is controlled at the size than the narrow lastblock fire grate segment of whole fire grate width.Main consider by the raw coal after sending have part will toward about two limits share, can increase coal seam thickness, may cause limit, left and right sides coal burning unclean.Two right-angle sides of hot rolling inequilateral angle iron are sealed with a moderate steel plate one (2) of width, also use steel plate two (3), steel plate three (4) to seal on two on hot rolling inequilateral angle iron again, form a 3-D triangle, the long limit of 3-D triangle is faced down to be placed on the fire grate.Use pipe one (5), the pipe two (6) of two equal length, one headband silk mouth again, parallel being welded on leg-of-mutton of the long right-angle side, use other pipe three (7), pipe four (8) to be connected on the preceding left and right sides wallboard of fire grate with the silk mouth respectively again, insert cooling water in the pipe, guarantee that coal-loosening device can be not overheated when operation and cause distortion and burn.Be spaced a distance in the coal-loosening device floor below again and burn-on several sections as abrasionproof usefulness, reduce the wearing and tearing of fire grate coal-loosening device with band iron (9).

This patent beneficial effect is to make simply, and is easy for installation, safe and reliable.

Description of drawings

Below in conjunction with drawings and Examples this patent is described further.

Fig. 1 is novel coal-loosening device mounting structure schematic diagram.

Fig. 2 is novel coal-loosening device structural representation.

(1) among the figure, hot rolling inequilateral angle iron, (2), steel plate one, (3), steel plate two, (4), steel plate three, the pipe one of (5), band silk mouthful, the pipe two of (6), band silk mouthful, (7), pipe three, (8), pipe four, (9), band iron.

The specific embodiment

Earlier novel coal-loosening device is lain on the grate surface, connect connection pipe three (7), pipe four (8) again, last pipe is connected cooling water, during operation, just can normally use as long as open cooling water.

Claims
