Description

A kind of Blowing stopper
Technical field
The utility model is related to a kind of Blowing stopper, more particularly to a kind of spray dryer Blowing stopper.
Background technology
It is known that the switch impeller bodies of existing Blowing stopper are mainly made up of steel plate or plastics, it is not provided with sealing and scrapes Plate, when closing discharging, switch impeller bodies are poorly sealed, easy leaked substance, when opening discharging, impeller pad wear is easily caused again and is added Play, shortens the service life of impeller blade, is unfavorable for the big workload of Blowing stopper, works long hours.
The content of the invention
When the utility model closes discharging for existing Blowing stopper, switch impeller bodies are poorly sealed, and easy leaked substance is opened When opening discharging, the aggravation of impeller pad wear is easily caused again, shortens the service life of impeller blade, is unfavorable for the big workload of Blowing stopper, length The technical problem of time service sets sealing scraper there is provided one kind, when closing discharging, and switch impeller bodies sealing is tight, is difficult Leaked substance, when opening discharging, does not result in the aggravation of impeller pad wear, extends the service life of impeller blade, be conducive to big work The Blowing stopper measure, worked long hours.
Therefore, a kind of Blowing stopper of the utility model, provided with Blowing stopper pedestal, Blowing stopper pedestal is provided with round cavity body, circle Shape inner chamber body upper end is provided with charging aperture, and round cavity body lower end is provided with discharging opening, round cavity body provided with switch impeller bodies, Switching impeller bodies includes impeller sleeve and impeller blade, and impeller sleeve is connected with power spindle, and impeller sleeve excircle is provided with Sealing scraper is provided with the outside of impeller blade, impeller blade.
Preferably, impeller blade quantity is 6-8.
Preferably, sealing scraper is rubber slab, and sealing scraper is detachably installed with impeller blade.
Preferably, sealing scraper and wall distance in round cavity body are less than 5mm.
The utility model beneficial effect is, because provided with Blowing stopper pedestal, Blowing stopper pedestal is provided with round cavity body, circular Inner chamber body upper end is provided with charging aperture, and round cavity body lower end is provided with discharging opening, round cavity body provided with switch impeller bodies, opened Closing impeller bodies includes impeller sleeve and impeller blade, and impeller sleeve is connected with power spindle, and impeller sleeve excircle is provided with leaf Take turns and sealing scraper is provided with the outside of piece, impeller blade.When closing discharging, switch impeller bodies sealing is tight, is difficult leaked substance, opens During discharging, the aggravation of impeller pad wear is not resulted in, extends the service life of impeller blade, is conducive to big workload, the length of Blowing stopper Time service.

Embodiment
The utility model is described further with reference to embodiment.
As shown in Figure 1, Figure 2, Figure 3 shows, it is a kind of embodiment of the present utility model, provided with Blowing stopper pedestal 2, Blowing stopper pedestal 2 are provided with round cavity body 15, and the upper end of round cavity body 15 is provided with charging aperture 4, and the lower end of round cavity body 15 is provided with discharging opening 5, circle Provided with switch impeller bodies 6 in shape inner chamber body 15, power spindle 3 is provided with the middle of switch impeller bodies 6, switch impeller bodies 6 are set There are impeller sleeve 14 and impeller blade 13, outside of the impeller blade 13 away from impeller sleeve 14 is provided with sealing scraper 11.Power spindle 3 leads to Cross power spindle left shaft holder 1 and power spindle right axle bearing 7 be connected with Blowing stopper pedestal 2, motor 8 is connected with power spindle 3, Such structure, when motor 8 shuts down, can realize closing discharging, sealing scraper 11 and the inner wall sealing of Blowing stopper pedestal 2 are tight It is real, it is difficult leaked substance;When motor 8 is operated, power spindle 3 drives switch impeller bodies 6 and sealing scraper 11 to rotate, Neng Goukai Discharging is opened, material is fallen into by charging aperture 4, and is discharged by discharging opening 5, sealing scraper 11 rubs with the inwall of Blowing stopper pedestal 2 flexibility, The abrasion aggravation of impeller blade 13 is not resulted in, extends the service life of impeller blade 13, is conducive to big workload, the long-time of Blowing stopper Work.
The quantity of impeller blade 13 is 6, and sealing scraper is with when wall distance is less than 5mm in round cavity body, can effectively prevent Only material from leakage, and can effective blowoff material.Sealing scraper 11 is rubber slab, can effectively reduce abrasion, and it is logical with impeller blade 13 The detachably installation of pressing plate 10, bolt 9, nut 12 is crossed, is convenient for changing, saves maintenance time and maintenance cost.
Only as described above, only specific embodiment of the utility model, when the utility model can not be limited with this The scope of implementation, therefore the displacement of its equivalent assemblies, or the equivalent variations made according to the utility model scope of patent protection and modification, It all should still belong to the category that the utility model claims are covered.
