Description

Multi-functional raker

Technical field

The utility model relates to a kind of mining device, relates in particular to a kind of multi-functional raker.

Background technology

The shortcoming that the CFBB point stove initial stage exists has: 1, the siege boiling is inhomogeneous, and the igniting bed material is prone to produce the dead band, does not seethe with excitement; 2, be prone to produce little coke button; 3, in operating process, be prone to produce than big coke block, clear up after causing boiler pressuring fire or blowing out; 4, in the some stove process because charcoal too much or grasp badly with wind, is easy to generate bed temperature and rises too fastly, rely on boiler air-supply can't cooling control, cause the coking of furnace charge integral body.What when 1,2 problems of processing, use at present is common self-control creeper, promptly utilize iron pipe welding rake teeth, but this creeper is very heavy; It is big in use to expend muscle power; And creeper is in burner hearth behind the overstand, and overheating deforming causes its intensity to reduce easily.And feel simply helpless for the common creeper of 3,4 problems, can only blowing out handle.

Summary of the invention

The purpose of the utility model provides a kind of sturdy and durable, easy to use, multi-functional raker that scarfing cinder is effective.

For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:

A kind of multi-functional raker comprises the air water mixing chamber, and the air water mixing chamber is a straight tube; It is characterized in that: the airtight wind regime control valve that is communicated with of air water mixing chamber one end; The airtight water source control valve that is communicated with of air water mixing chamber sidepiece, the airtight burst-chamber that is communicated with of the air water mixing chamber other end, burst-chamber also are a straight tube; The airtight explosive cartridge that is communicated with of burst-chamber sidepiece, the airtight raker that is communicated with of the burst-chamber other end.

According to described multi-functional raker, it is characterized in that: said raker free end is for most advanced and sophisticated.

According to described multi-functional raker, it is characterized in that: the airtight rake teeth that is communicated with of the said raker other end, rake teeth is the straight tube of many hollows.

Because the chief component of the utility model adopts hollow structure, can in stove, water flowing ventilate, effectively to lowering the temperature in the stove; Prevent that raker from being crumpled; Therefore sturdy and durable, tip and rake teeth through raker can well go out the slag fragmentation clearly, and be easy to use.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

A kind of multi-functional raker to shown in Figure 4, comprises air water mixing chamber 3 like Fig. 1; Air water mixing chamber 3 is a straight tube, the airtight wind regime control valve 2 that is communicated with of air water mixing chamber 3 one ends, the airtight water source control valve 1 that is communicated with of air water mixing chamber 3 sidepieces; The airtight burst-chamber 5 that is communicated with of air water mixing chamber 3 other ends; Burst-chamber 5 also is a straight tube, the airtight explosive cartridge 4 that is communicated with of burst-chamber 5 sidepieces, the airtight raker 6 that is communicated with of burst-chamber 5 other ends.In the present embodiment, raker 6 free ends are most advanced and sophisticated 7.In the present embodiment, the airtight rake teeth 8 that is communicated with of raker 6 other ends, rake teeth 8 is the straight tube of many hollows.

Embodiment recited above describes the preferred implementation of the utility model; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design concept, common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model; The technology contents that the utility model is asked for protection all is documented in claims.

The utility model embodiment one can be used in combination with embodiment two described two kinds of rakers.

In burner hearth, meet the shortcoming that heat is yielding, intensity reduces to common creeper; The utility model is made hollow with raker; It is the seamless steel pipe weldering system of 20mm that chief component adopts diameter, and rake teeth adopts the tip tubule, can blowing-in and combustion-supporting when charcoal burning; The rake teeth inner ventilation, little coke button can rapidly it be cleaned out burner hearth when producing, owing to can be avoided being crumpled; Open Side Down owing to rake teeth simultaneously, and by the reaction force of wind, raker has been reduced worker's labour intensity by the jack-up that makes progress; When in the burner hearth during temperature drift, can connect wind regime and water source simultaneously, form water smoke at the rake teeth place and reduce fire box temperature, can avoid the burner hearth large-area coking; When meeting big coke block, can utilize to have most advanced and sophisticated raker, the tip of raker is inserted in the big coke block; Firecrackers are lighted at the place at explosive cartridge; Open the wind that the wind regime control valve feeds 0.5MPa then, firecrackers are blown in the big coke block, the impulsive force of utilizing the firecrackers instant of detonation to produce; Big coke block is fried diffusing, clean out burner hearth to little coke button with the raker that has rake teeth again.

The use of multi-functional raker can produce many effects:

1, save power.But air-introduced machine save power 555 degree of 185KW, but air-introduced machine save power 1200 degree of 400KW.

2, reduce worker's labour intensity.Reaction force through wind makes that raker is little to float on blast cap top, has alleviated worker's physical demands.

3, security performance is high.Whole operations is all accomplished outside the burner hearth manhole door, and after avoiding coking occurring in the burner hearth, the phenomenon of high temperature coke cleaning is emitted in manual work.

4, some stove success rate improves.The problem that has occurred when having overcome in the charcoal ignition process by cold conditions to hot the variation.

At a charcoal initial stage, utilize the raker that has rake teeth in charcoal, to stir air-supply, can also help charcoal burning.There is the boiling dead band at the ignition of the boiler initial stage, and little coke button is arranged simultaneously, because the rake teeth inner ventilation, it is overheated that rake teeth is unlikely, and therefore is easy to coke cleaning.

If use air-introduced machine need 3 hours combustion-supporting, but save power 555 degree (185KW) are spent (400KW) with 1200.

The point stove initial stage is because the part charcoal burning is insufficient, after pressure fan starts; Charcoal fully burns, and is prone in the burner hearth produce high temperature, at this moment opens wind regime control valve and water source control valve simultaneously; Can produce water smoke at the rake teeth place, can make the burner hearth cooling rapidly, avoid coking phenomenon.
