Abstract
The utility model discloses a kiln dust collector, include and pass through the sack cleaner that cleaning tube is connected with the chimney of kiln, there is not gap junction between cleaning tube and the chimney, the last bypass pipeline that still is equipped with of cleaning tube, the bypass pipeline is walked around the sack cleaner, be equipped with valve no. 1 on the bypass pipeline, the air inlet and the gas outlet punishment of sack cleaner do not are equipped with valve no. 2 and valve no. 3, the sack cleaner below is connected with the compressed air pipe way, compressed air pipe is equipped with the electromagnetic pulse pneumatic valve on the road, the utility model discloses a kiln dust collector can in time discharge the aggressive fume of kiln intracavity, extension kiln life.
Description
Technical field
The utility model relates to a kind of cleaning apparatus, in particular to the cleaning apparatus on a kind of kiln.
Background technology
Kiln can produce high temperature corrosion gas in the product process such as manufacture VN alloy, and gas is mingled with a large amount of dust granules, as cleared up not in time, being trapped in kiln chamber can at kiln scale inside furnace, the refractory materials that corrosion is inner, reduces the work-ing life of kiln.
As shown in Figure 1, existing kiln adds cleaning apparatus, but there is certain interval between cleaning shaft and chimney, dedusting can be caused so on the one hand not thorough, cannot discharge corrosive gases in time; The pressure in kiln chamber cannot be ensured on the other hand, product quality can be produced certain impact.
Meanwhile, bag-type dust collector works after for some time, understands and gather a large amount of dust at cloth bag inwall, affects normal dust removing effects, it is necessary to must interval for some time carry out unloading ash. Existing kiln cleaning apparatus needs when unloading ash to cut out dedusting fan, kiln cavity pressure is raised, in order to make corrosive gases discharge in time, can only close down kiln, have impact on normal production operation.
Practical novel content
For solving the problems of the technologies described above, the utility model provides a kind of kiln cleaning apparatus, ensures kiln cavity pressure all the time to reach, and extends kiln work-ing life, does not delay the object of normal production.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of kiln cleaning apparatus, comprise the sack cleaner that the chimney with kiln is connected by cleaning shaft, seamless connectivity between described cleaning shaft and chimney, described cleaning shaft is also provided with bypass duct, described bypass duct walks around described sack cleaner, described bypass duct is provided with valve one, and the inlet mouth of described sack cleaner and air outlet place are respectively equipped with valve two and valve three; Being connected with pneumatic line below described sack cleaner, described pneumatic line is provided with emp pneumavalve.
In such scheme, described cleaning shaft end is connected with dedusting fan.
In further technical scheme, described dedusting fan is frequency conversion adjustable fan, by adjusting the frequency of blower fan, ensures the pressure in kiln chamber.
Pass through technique scheme, seamless connectivity between the cleaning shaft of the kiln cleaning apparatus that the utility model provides and chimney, the flue dust that kiln is discharged directly enters cleaning shaft, by automatically regulating the electric machine frequency control exhausting amount of dedusting fan, it is achieved keep the pressure in kiln chamber constant; Due to gapless between chimney and cleaning shaft, dedusting fan electric machine frequency is less than 50HZ, it is possible to brownout.
Simultaneously, cleaning shaft adds bypass duct, unload in ash process at sack cleaner, do not need to stop dedusting fan, ensure all the time to avoid the pressure-stabilisation in kiln chamber because closing down dedusting fan when sack cleaner unloads ash, kiln cavity pressure is raised, corrosive gases gathers cannot discharge in time, causes gas fouling in kiln, corrosion refractory materials.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, it is briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
Fig. 1 is the mode of connection of kiln cleaning apparatus in prior art;
Fig. 2 is the structural representation of a kind of kiln cleaning apparatus disclosed in the utility model embodiment.
In figure, 1, kiln; 2, chimney; 3, cleaning shaft; 4, sack cleaner; 5, bypass duct; 6, valve one; 7, valve two; 8, valve three; 9, pneumatic line; 10, emp pneumavalve; 11, dedusting fan.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The utility model provides a kind of kiln cleaning apparatus, structure as shown in Figure 2, and this cleaning apparatus structure is simple, it is ensured that the pressure in kiln chamber, ensures product quality, extends kiln work-ing life.
Kiln cleaning apparatus as shown in Figure 2, comprise the sack cleaner 4 that the chimney 2 with kiln 1 is connected by cleaning shaft 3, seamless connectivity between cleaning shaft 3 and chimney 2, cleaning shaft 3 is also provided with bypass duct 5, bypass duct 5 walks around sack cleaner 4, bypass duct 5 is provided with valve 1, and the inlet mouth of sack cleaner 4 and air outlet place are respectively equipped with valve 27 and valve 38; Being connected with pneumatic line 9 below sack cleaner 4, pneumatic line 9 is provided with emp pneumavalve 10.
Cleaning shaft 3 end is connected with dedusting fan 11, and dedusting fan 11 is frequency conversion adjustable fan, by adjusting the frequency of dedusting fan 11, ensures the pressure in kiln chamber.
Under standard state, valve-off 1 when pushed bat kiln is normally bled, open valve 27 and valve 38, and pushed bat kiln Exhaust Gas is filtered by sack cleaner 4, discharges after filtration again, reaches environmental protection object; Often cross 12h and cloth bag is removed primary dusts, first reduce dedusting fan 11 rotating speed frequency during bag-type dust, then open valve 1, valve-off 27 and valve 38, ensureing that kiln cavity pressure is about 10Pa, start emp pneumavalve 10, cloth bag is blown by pressurized air to be swept, after dedusting, stop emp pneumavalve 10, open valve 27 and valve 38, valve-off 1, regulate dedusting fan 11 rotating speed frequency, ensure kiln cavity pressure about 10Pa.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are enable to realize or use the utility model. To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments. Therefore, the utility model can not be limited in these embodiments shown in this article, but be met the widest scope consistent with principle disclosed herein and features of novelty.
