Embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
Please refer to Fig.1,2, cooperation refer to Fig. 3-5, show that a kind of rotary valve material that the utility model is related to is defeated in figure
Clamp-proof mechanism is sent, its key technology scheme is：
The rotary valve material conveys clamp-proof mechanism, including rotary valve shell 9 and its rotor 10, rotary valve shell 9 are equipped with
The feed inlet 11 of rotary valve；The feed inlet 11 of rotary valve 9 is equipped with the feeding cylinder 3 with the axis perpendicular of rotor 10；
The inner wall axial direction both sides of feeding cylinder 3 were respectively equipped with the upper feeding baffle 4 in axle center and lower charging baffle 7 up and down；
The top of feeding cylinder 3 is equipped with the upper flange 5 that can be located by connecting with external equipment, its underpart be equipped with can with rotary valve into
The lower flange 2 that material mouth 11 is located by connecting；
The upper flange mouth of feeding cylinder 3 is feed inlet E, and the lower end of feeding cylinder 3 is discharge port F；
The discharge port F axial directions both sides of feeding cylinder 3 are respectively equipped with the left plate 1 and right plate 8 for sloping inwardly and setting, left plate
1 and the angle of inclination of right plate 8 be adapted with 11 longitudinal section shape of feed inlet of rotary valve 3.
Upper feeding baffle 4 after a pair of combine in the plate of inner concavity structure by forming, after lower charging baffle 7 is combined by a pair
Formed in the plate of outer gibbosity structure.
The utility model is related to rotary valve material conveying clamp-proof mechanism operation principle approximately as：
The clamp-proof mechanism upper flange that the utility model is related to is connected with gravity stream material pipe or feed bin, and lower flange is the same as rotation
Rotary valve connects., will transported elastic particle when being rotated clockwise during the rotor of rotary valve is according to Fig. 1 shown in arrow
Enter clamp-proof mechanism from upper flange, after overhead gage, material flow reduces, and flows down in the guide functions of overhead gage to lower block
Plate, and second of reduction of speed is carried out, in the rotor for finally flowing slowly into rotary valve, blanking velocity is reduced due to continuous, is avoided
Resilient materials are jumped seriously so that elastic particle enters between rotary valve rotor blade and housing, causes getting stuck for rotary valve.
The utility model is upper and lower arrangement using double baffle designs.It is direct that upper feeding baffle avoids particulate material
Rotary valve rotor is impacted, while current limliting has also been carried out to the flow of material；Lower charging baffle avoids elastic particle and is directly entered
The region of engagement of rotary valve rotor and housing, avoids particle and enters engagement gap, also avoid getting stuck for rotary valve.
The primary structure and material for the rotary valve material conveying clamp-proof mechanism that the utility model is related to：
Rotary valve material conveys clamp-proof mechanism mainly by being vertically connected with flange, feeds baffle, left side plate and cylinder up and down
Composition.

To after overhead gage 4, particle flow velocity is reduced, and upper feeding baffle 4 guide functions flow down downwards charging baffle 7, encounter
After lower baffle plate charging 7, the flow velocity of particle, which has obtained second, to be reduced, and the rotor 10 of rotary valve is finally flowed slowly into from discharge port F
Cavity in.
Clamp-proof mechanism uses double baffle designs, and upper and lower arrangement.Upper feeding baffle 4 uses concave structure, first
The particle quickly flowed down from feed bin or gravity stream pipeline is blocked into reduction of speed, avoids the rotor 10 that particle directly impacts rotary valve,
In turn result in the phenomenon that gets stuck.Secondly, the effect of material current limliting is also played.Lower charging baffle 7 uses convex shape, has both played limit
The effect of reduction of speed is flowed, avoids elastic particle from being directly entered the region of engagement of rotary valve rotor 10 and housing 9, rotary valve is got stuck
Failure；Uniform divided flows function is played again, the particle into clamp-proof mechanism is uniformly distributed as far as possible on rotary valve axial direction.
3 lower half of cylinder of clamp-proof mechanism is plugged to 9 top of rotary valve shell, the lower half of cylinder 3 to the greatest extent may be used
The rotor 10 close to rotary valve of energy, while under the collective effect of left plate 1 and right plate 8, it is entirely avoided particulate material is straight
The region of engagement into rotor 10 and rotary valve shell 9 is tapped into, has prevented the probability that rotary valve gets stuck.
In addition, the utility model clamp-proof mechanism be also respectively configured on the cylinder body outer wall of feeding cylinder 3 electrostatic grounding ear 6,
12, caused electrostatic is outwards drawn when can effectively equipment be run.
Above example is only for illustration of the utility model, rather than the limitation to the utility model, related technical field
