Abstract

The utility model discloses an element composed into a cross-frame fire grate which can be composed of the boiler, in particular to a new typed fire grate. The utility model contains a fire grate body [4], the upper fire grate body [4] is provided with cross wind threads [1], the fire grate body from up to down is provided with stand wind threads [2], and the lateral surface of the fire grate body is provided with a reinforcing rib [5]. The utility model is characterized in that the spacing of the cross wind threads [1] are 9 mm-15 mm, and every cross wind thread is corresponding to a stand wind thread [2]. Compared with the present technology, the utility model has advantages of high strength, good quality in air feeding to the top of the fire grate, unblocking, sufficient burning, and the burner is not produced when the fuel is burned.

Description

The crossbeam type chain-grate fire grate segment

Technical field:

The utility model relates to a kind of member of forming boiler crossbeam fire grate, particularly a kind of crossbeam type chain-grate fire grate segment.

Background technology:

Have chain fire-gate boiler and be widely used in industrial and agricultural production, boiler its fuel in running places on the crossbeam fire grate of rotation, burns on the crossbeam fire grate.Described crossbeam fire grate be by chain and on crossbeam and the parts such as fire grate segment that are arranged on the crossbeam constitute, existing fire-grating chip architecture is: a fire grate segment body is arranged, be provided with at interval horizontal tranverse wind line and vertical wind line longitudinally above, the fuel air feed above fire grate by tranverse wind line and vertical wind line, it is fully burnt, tranverse wind line spacing on the fire grate segment is 25 millimeters at present, the vertical wind line of each fire grate segment has three, be the long and narrow line of rabbet joint, i.e. the corresponding several tranverse wind lines of the long and narrow line of rabbet joint.It is that the cloth wind of fire grate segment top is inhomogeneous, and long and narrow vertical wind line makes air intake blow to the little place of resistance, fire grate segment top, makes this place generation burner, and the big local incomplete combustion of resistance.Because there is the reinforcement of broad the side of fire grate segment body, can stop when the vertical wind line windward, influences the air feed quality.Existing fire grate segment body intensity is low, easy fracture.

Summary of the invention:

The purpose of this utility model provides a kind of intensity height, air feed is even, burning quality good, do not produce the crossbeam type chain-grate fire grate segment of burner, overcomes the deficiencies in the prior art.

Technical solution of the present utility model is: a kind of crossbeam type chain-grate fire grate segment, it comprises fire grate segment body 4, on fire grate segment body 4, be provided with tranverse wind line 1, from on face down and be provided with vertical wind line 2, the side is provided with reinforcement 5, it is characterized in that: the spacing of described tranverse wind line 1 is: 9 millimeters-15 millimeters, and each tranverse wind line 1 corresponding vertical wind line 2.

Described vertical wind line 2 is the semicircle flute profile.

The below of described fire grate segment body 4 is provided with reinforcement 3.

The reinforcement 5 of described fire grate body 4 sides is inwardly withdrawn.

The utility model compared with prior art has the intensity height, to fire grate segment top the air feed quality good, do not stop, fuel does not produce burner, sufficient combustion when burning advantage.

Description of drawings:

Fig. 1 is the structural representation of the utility model specific embodiment;

Fig. 2 is a schematic top plan view shown in Figure 1;

Fig. 3 is two structural representations that fire grate segment is set up in parallel;

Fig. 4 is a schematic top plan view shown in Figure 3;

Fig. 5 is a B-B sectional schematic diagram shown in Figure 3.

The specific embodiment:

As shown in the figure: 4 is the fire grate segment body, evenly is provided with horizontal groove shape tranverse wind line 1 at interval in the above, and the bottom surface of tranverse wind line 1 is arc surfaced, and the spacing minimum of tranverse wind line is 9 millimeters, is 15 millimeters to the maximum, the wind supply quantity during with the assurance operation.On fire grate segment body 4, be positioned at tranverse wind line 1 place have one upright to be top-down vertical wind line 2, the corresponding vertical wind line of each tranverse wind line, vertical wind line 2 is vertically arranged with respect to fire grate segment body 4, change the date and become the vertical wind line arrangement architecture of long and narrow in the prior art, overcome the shortcoming that air intake blows towards the little place of resistance, do not produced burner.The centre position is provided with reinforcement 3 below fire grate segment body 4, and reinforcement 3 is structure as a whole with fire grate segment body 4.Improved its intensity, not easy fracture.Reinforcement 5 on the side of fire grate segment body 4 is inwardly withdrawn, and promptly the narrowed width of reinforcement 5 has overcome reinforcement 5 outsides and the concordant shortcoming of keeping out the wind of fire grate segment body 4 sides in the prior art, has improved the quality of air feed.

Claims
