As preferred version: described dust gathering arrester is provided with handle, and the lower ending opening of dust gathering arrester is apart from fire door 25-30cm.Arranging and facilitating employee's rotary collecting dust hood of handle, adjusts optimum position, and dust gathering arrester both facilitated from the height of fire door that employee is reinforced to slag tap, and convenience and high-efficiency is collected flue dust again.
As preferred version: described minute airflow pipeline and primary air pipeline are the pipe that the iron sheet of thickness 2-3mm is made, and all scribble antirust paint on interior lateral wall.Effectively the corrosivity of opposing flue dust, extends the pipeline life-span.
As preferred version: a described absorption spray bucket internal upper part is provided with layer of active carbon filter course, on the madial wall of activated carbon filter layer below, a plurality of spray nozzles are installed, the bottom of described absorption spray bucket is also provided with the circulating pump of bottom of the barrel current being sent back to spray nozzle.
As preferred version: described absorption spray bucket, the bottom of settling vat and water film dedusting bucket group is equipped with firth outlet hole.Convenient in time to clearing up in bucket.
The utility model, owing to having adopted above-mentioned technical scheme, is arranged on dust gathering arrester the side of intermediate frequency furnace, and the opening of dust gathering arrester is greater than to fire door, can under the prerequisite that does not affect operation, better collect flue dust; Dust gathering arrester is connected with a minute airflow pipeline by rotary flange dish, dust gathering arrester can be take and divide an airflow pipeline to be rotated as axle center, and then make the position-adjustable of dust gathering arrester, has improved the pick-up performance of dust gathering arrester; The utility model is simple in structure, and pick-up performance is good, applied widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is made a detailed explanation.
A kind of intermediate frequency furnace dust pelletizing system as shown in Figure 1, comprise dust gathering arrester 2, divide airflow pipeline 5, primary air pipeline 6, absorption spray bucket 7, settling vat 8, spiral case blower fan 9 and water film dedusting bucket group 10, described dust gathering arrester 2 is arranged on a side of intermediate frequency furnace 1 top, the lower ending opening of dust gathering arrester 2 extends to directly over fire door, and the lower ending opening of dust gathering arrester 2 is greater than fire door, the internal diameter of described dust gathering arrester 2 smoothly successively decreases from down to up, the upper end of described dust gathering arrester 2 is connected by rotary flange dish 4 with a minute airflow pipeline 5, during use, dust gathering arrester 2 can rotate and depart from a little fire door, position along with wind direction decision cover, within described minute, airflow pipeline 5 is connected to absorption spray bucket 7 by primary air pipeline 6, and described spray bucket 7 is connected to settling vat 8, and settling vat 8 is connected to water film dedusting bucket group 10, and described spiral case blower fan 9 is arranged between settling vat 8 and water film dedusting bucket group 10.
The interior position near rotary flange dish 4 of described dust gathering arrester 2 is also provided with air door 3, and described air door 3 is connected with the pull bar that hangs over dust gathering arrester 2 outsides.Described dust gathering arrester 2 is provided with handle, and the lower ending opening of dust gathering arrester 2 is apart from fire door 25-30cm.
Described minute airflow pipeline 5 and primary air pipeline 6 are the pipe that the iron sheet of thickness 2-3mm is made, and on interior lateral wall, all scribble antirust paint.Simultaneously on minute airflow pipeline 5 and primary air pipeline 6, do insulation material, the flue dust that has like this temperature to workshop release heat seldom, keeps the nice and cool of workshop in summer in pipeline.
Described absorption spray bucket 7 internal upper parts are provided with layer of active carbon filter course 71, and a plurality of spray nozzles 72 are installed on the madial wall of activated carbon filter layer 71 belows, and the bottom of described absorption spray bucket 7 is also provided with the circulating pump of bottom of the barrel current being sent back to spray nozzle 72.Described absorption spray bucket 7, the bottom of settling vat 8 and water film dedusting bucket group 10 is equipped with firth outlet hole 12.
The course of work: a set of stove is generally comprised of two intermediate frequency furnaces 1 and a switch board, general only with an intermediate frequency furnace 1 and switch board during blow-on, another intermediate frequency furnace 1 is standby, also interchangeable blow-on.Because dust gathering arrester 2 has adopted two stove central rotation structures, to be so no matter which stove work, dust gathering arrester 2 can be rotated to this stove top and operate.
From primary air pipeline 6 the insides flue dust out, enter through absorption spray bucket 7, after activated carbon filter layer 71 absorption, through the spray of bottom spray nozzle 72, in flue dust, most particle and nuisances is adsorbed and precipitates so again, circulating pump reciprocation cycle spray.Remaining gas is in settling vat 8, and with a small amount of aqueous vapor, after the interior sedimentation of settling vat 8, dry a little gas is sent in water film dedusting bucket group 10 through spiral case blower fan 9, so just can not corrode blower fan.In water film dedusting bucket group 10, water adsorbs remaining nuisance and is precipitated again, then improves chimney 11 and be discharged in atmosphere, has been relatively cleaner pure air, is conducive to environmental protection.
Can the supporting a set of dust pelletizing system of independent a set of stove, also can consider multiple muffle furnace and use a set of dust pelletizing system together, but stove has also lacked waste pipeline and blower fan apparatus, stove is also many, pipeline is oversize, exhausting weak effect, at present most suitable is that two cover stoves are also used a set of dust pelletizing system together.
