Abstract
The invention relates to an automatic descaling discharging valve, which comprises a valve body, and is characterized in that: a valve shaft is arranged in the valve body; an impeller is distributed on the valve shaft; meanwhile, a dust scraping component extends from the outer end of the impeller. Therefore, a scraping plate is arranged between the side face of the impeller and the valve body and scrapes dust deposit and carbon deposit in a gap with the rotation of the impeller, dust is discharged together with a material from the gap on the lower part of a cavity, and the phenomenon that the impeller is blocked is avoided.
Description
Technical field
The present invention relates to a kind of discharge valve, relate in particular to a kind of automatic descaling type discharge valve.
Background technology
Present this kind valve pumped (conveying) medium dust, coal dust or other dried particles material.
But because media environment, dust granules can produce dust stratification, carbon distribution in the gap of the two sides of valve body and impeller.Cause running clearance to dwindle at last, rotation friction strengthens, and produces stuck phenomenon, increases the rotating load of motor, the final consequence of burning motor that produces.
Summary of the invention
The objective of the invention is to overcome the above problem that prior art exists, a kind of automatic descaling type discharge valve is provided.
For realizing a kind of automatic descaling type discharge valve of the object of the invention, include valve body, wherein: be provided with valve shaft in the described valve body, be distributed with impeller on the described valve shaft; Described impeller outer end is extended with dust scraping assembly.
Further, above-mentioned a kind of automatic descaling type discharge valve, wherein, described dust scraping assembly is a scraper plate.
Further, above-mentioned a kind of automatic descaling type discharge valve, wherein, described scraper plate does not contact with valve interior wall.
Again further, above-mentioned a kind of automatic descaling type discharge valve, wherein, described valve shaft one side is provided with motor and assists coupling assembling.
Adopt technical scheme of the present invention, between impeller side and valve body, set up scraper plate, all by the rotation of scraper plate with impeller, dust stratification, carbon distribution in the gap are carried out scraping, ash is discharged with material from the cavity underclearance, avoids the stuck phenomenon of impeller.
The object of the invention, advantage and characteristics will illustrate through the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
Description of drawings
Fig. 1 is the organigram of this automatic descaling type discharge valve.
The implication of each Reference numeral is following among the figure:
1 valve body, 2 impellers
3 scraper plates, 4 valve shafts
5 motors assist coupling assembling
The specific embodiment
A kind of automatic descaling type discharge valve as shown in Figure 1 includes valve body 1, and its unusual part is: be provided with valve shaft 4 in the valve body 1 that the present invention adopts.And, on valve shaft 4, be distributed with impeller 2.Simultaneously, be extended with dust scraping assembly in impeller 2 outer ends.
In conjunction with the present invention's one preferred implementation, in order effectively the dust stratification in impeller 2 and the chamber, valve body 1 both sides to be scraped completely, the dust scraping assembly of employing is a scraper plate 3.Simultaneously, consider that the existence of scraper plate 3 can not cause motion to hinder to the impeller 2 that valve shaft 4 drives, the scraper plate 3 that the present invention adopts does not contact with valve body 1 inwall.
Further, be connected with motor, can help motor simultaneously impeller 2 is carried out the actv. driving, be provided with motor in valve shaft 4 one sides and assist coupling assembling 5 for the ease of the present invention.
In conjunction with actual condition of service of the present invention: set radial scraper plate 3 by feat of impeller 2 both sides.When valve moved, motor was through 2 rotations of valve shaft 4 impeller.Immediately, in rotary course, the scraper plate 3 that is arranged on impeller 2 two sides can carry out one with dust stratification in the chamber, valve body 1 both sides and scrapes motion remaining in impeller 2.Afterwards, ash is together discharged with medium from the valve body 1 and the outlet gap of impeller 2, thereby reduces the accumulation of ash in the cavity between valve body 1 and the impeller 2.Thus, can prevent effectively that the motor load that causes because of valve pocket carbon distribution, dust stratification from increasing phenomenon.And, can remove the appearance of burning bad phenomenon such as motor from, improved the operation life of valve.
Through above-mentioned character express and combine accompanying drawing to find out; After adopting the present invention; Between impeller side and valve body, set up scraper plate,, dust stratification, carbon distribution in the gap are carried out scraping all by the rotation of scraper plate with impeller; Ash is discharged with material from the cavity underclearance, avoids the stuck phenomenon of impeller.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.Except that the foregoing description, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
