Description
Technical field
The present invention relates to a kind of Blowing stoppers, 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 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, and easily cause impeller pad wear and add
The service life of impeller blade is shortened in play, is unfavorable for the big workload of Blowing stopper, works long hours.
Invention content
When the present invention closes discharging for existing Blowing stopper, switch impeller bodies are poorly sealed, and easy leaked substance, unlatching is unloaded
When material, and the aggravation of impeller pad wear is easily caused, shortens the service life of impeller blade, be unfavorable for the big workload of Blowing stopper, long-time
The technical issues of work, provides a kind of setting sealing scraper, and when closing discharging, switch impeller bodies sealing is tight, is not easy to leak
Material when opening discharging, will not cause impeller pad wear to aggravate, extend the service life of impeller blade, be conducive to big workload, length
The Blowing stopper of time service.
For this purpose, a kind of Blowing stopper of the present invention, it is equipped with Blowing stopper pedestal, Blowing stopper pedestal is equipped with round cavity body, in circle
Cavity upper end is equipped with feed inlet, and round cavity body lower end is equipped with discharge port, switch impeller bodies, switch are equipped in round cavity body
Impeller bodies include impeller sleeve and impeller blade, and impeller sleeve is connect with power spindle, and impeller sleeve excircle is equipped with impeller
Piece, impeller blade outside are equipped with sealing scraper.
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.
Present invention has the advantages that due to being equipped with Blowing stopper pedestal, Blowing stopper pedestal is equipped with round cavity body, round cavity
Body upper end is equipped with feed inlet, and round cavity body lower end is equipped with discharge port, switch impeller bodies are equipped in round cavity body, switch leaf
Wheel body includes impeller sleeve and impeller blade, and impeller sleeve is connect with power spindle, and impeller sleeve excircle is equipped with impeller blade,
Sealing scraper is equipped on the outside of impeller blade.When closing discharging, switch impeller bodies sealing is tight, is not easy leaked substance, opens discharging
When, impeller pad wear will not be caused to aggravate, extend the service life of impeller blade, be conducive to big workload, the long-time of Blowing stopper
Work.

Specific implementation mode
The present invention 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 invention, is equipped with Blowing stopper pedestal 2, Blowing stopper pedestal 2 is set
There is a round cavity body 15,15 upper end of round cavity body is equipped with feed inlet 4, and 15 lower end of round cavity body is equipped with discharge port 5, in circle
It is equipped with switch impeller bodies 6 in cavity 15, power spindle 3 is equipped among switch impeller bodies 6, switch impeller bodies 6 are equipped with leaf
Axle sleeve 14 and impeller blade 13, outside of the impeller blade 13 far from impeller sleeve 14 are equipped with sealing scraper 11.Power spindle 3 passes through dynamic
Advocate axis left shaft holder 1 and power spindle right axle bearing 7 is connect with Blowing stopper pedestal 2, motor 8 is connect with power spindle 3, in this way
Structure can realize closing discharging when motor 8 shuts down, sealing scraper 11 and 2 inner wall sealing of Blowing stopper pedestal are tight,
It is not easy leaked substance；When motor 8 operates, power spindle 3 drives switch impeller bodies 6 and sealing scraper 11 to rotate, and can open
Discharging, material are fallen by feed inlet 4, and are discharged by discharge port 5, and sealing scraper 11 rubs with 2 inner wall flexibility of Blowing stopper pedestal, no
The abrasion aggravation of impeller blade 13 can be caused, extends the service life of impeller blade 13, is conducive to big workload, the long-time work of Blowing stopper
Make.
13 quantity of impeller blade is 6, and sealing scraper can effectively be prevented with when wall distance is less than 5mm in round cavity body
Only material leakage, and can effective blowoff material.Sealing scraper 11 is rubber slab, can effectively reduce abrasion, logical with impeller blade 13
It crosses pressing plate 10, bolt 9, nut 12 detachably to install, be convenient for changing, save maintenance time and maintenance cost.
Only as described above, only specific embodiments of the present invention, when the model that cannot be limited the present invention with this and implement
It encloses, therefore the displacement of its equivalent assemblies, or according to equivalent variations made by scope of patent protection of the present invention and modification, all should still belong to this hair
The scope that bright claims are covered.
