The utility model content
The technical problems to be solved in the utility model is, for the deficiency that prior art exists, provides a kind of and can prevent that pellet is extruded broken materials bitten prevention rotation inlet valve by actv..
The utility model is that the technical scheme that its technical matters of solution adopts is:
Materials bitten prevention rotation inlet valve provided by the utility model comprises: valve body and rotor,
Described valve body comprises feeding mouth, discharging opening and hollow chamber, described hollow chamber both lateral sides opening, and described hollow chamber is connected with feeding mouth and discharging opening;
Described rotor comprises rotating shaft and wheel blade, and described wheel blade has some, is radial and is distributed in the rotating shaft, and described wheel blade outermost end is pointed switch-plate;
Described rotor laterally is installed in the hollow chamber of described valve body, and rotating shaft is stretched out outside the valve body by hollow chamber's both lateral sides opening;
Wherein offer the wedge shape guide groove near the feeding mouth place on the sidewall of valve body hollow chamber inside, the outside narrow inside of described wedge shape guide groove is wide, and the whole top narrow lower portion of wedge shape guide groove is wide.
In another preference, described wedge shape guide groove has two, lays respectively on the sidewall of the inner both sides of valve body hollow chamber.
In another preference, on described body wall, also be provided with the pore that is connected with hollow chamber.
In another preference, at described valve body feeding mouth the feeding mouth flange is set, at described valve body discharging opening the discharging opening flange is set.
In another preference, the material of described materials bitten prevention rotation inlet valve is corrosion-resistant steel or carbon steel or other wear-resistant materials.
Implement materials bitten prevention rotation inlet valve of the present utility model, have following beneficial effect:
1, owing to being provided with outer narrow inner width in the internal side wall of valve body hollow chamber, up-narrow and down-wide wedge shape guide groove can make pellet enter more easily guide groove and falls down, and can not produce pellet and be extruded broken situation in guide groove;
2, owing to there not being pellet to be extruded broken situation generation, whole rotation inlet valve is difficult for producing large vibrations in the running, so the noise that has produced when having reduced running;
3, owing to not having too much extruding and vibrations, the service life of whole rotation inlet valve all to obtain prolongation.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of valve body in the materials bitten prevention rotation inlet valve of the present utility model;
Fig. 2 is the structural representation of materials bitten prevention rotation inlet valve rotor of the present utility model;

Fig. 4 is the section-drawing of A-A among Fig. 3;
Fig. 5 is the structural representation of wedge shape guide groove in the materials bitten prevention rotation inlet valve of the present utility model.
Among the figure, 1, valve body, 2, rotor, 11, feeding mouth, 12, discharging opening, 13, hollow chamber, 14, the wedge shape guide groove, 15, pore, 16, the feeding mouth flange, 17, the discharging opening flange, 21, rotating shaft, 22, wheel blade, 23, switch-plate.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with embodiment and accompanying drawing, the utility model is further described:
Fig. 1 to Fig. 3 has illustrated materials bitten prevention provided by the utility model to rotate the structure of inlet valve, this materials bitten prevention rotation inlet valve comprises valve body 1 and rotor 2, valve body 1 comprises feeding mouth 11, discharging opening 12 and hollow chamber 13, described hollow chamber 13 both lateral sides openings, and described hollow chamber 13 is connected with feeding mouth 11 and discharging opening 12; Rotor 2 comprises rotating shaft 21 and wheel blade 22, and wheel blade 22 has some, is radial and is distributed in the rotating shaft 21, and wheel blade 22 outermost end are pointed switch-plate 23; Rotor 2 laterally is installed in the hollow chamber 13 of valve body, and rotating shaft 21 is stretched out outside the valve body 1 by hollow chamber's 13 both lateral sides openings; Offer wedge shape guide groove 14 near feeding mouth 11 places on the sidewall of valve body hollow chamber 13 inside, described wedge shape guide groove 14 outside narrow inside are wide, and the whole top narrow lower portion of wedge shape guide groove 14 is wide.Described wedge shape guide groove 14 has two, lays respectively on the sidewall of valve body hollow chamber 13 inner both sides.Also be provided with the pore 15 that is connected with hollow chamber 13 on described valve body 1 sidewall.At valve body feeding mouth 11 feeding mouth flange 16 is set, at valve body discharging opening 12 discharging opening flange 17 is set.The material of described materials bitten prevention rotation inlet valve is corrosion-resistant steel or carbon steel or other wear-resistant materials.
During materials bitten prevention rotation inlet valve work of the present utility model, by driver drives rotor 2 around the shaft 21 rotations in valve inner hollow chamber 13, material enters from feeding mouth 11, drops between the wheel blade 22 of rotor, along with the rotation of wheel blade 22 is brought to outside the discharging opening 12 output valve bodies 1.Because when the conveying granular material, the pellet on the pointed switch-plate 23 can be dialled to both sides when wheel blade rotates and move, after the sidewall of valve body hollow chamber 13 inside arranged wedge shape guide groove 14, pellet just can not be compressed between wheel blade and the sidewall.And because wedge shape guide groove 14 outside narrow inside are wide, the top narrow lower portion is wide, thus pellet can enter smoothly guide groove 14 and fall into back in the chamber from guide groove, and can be squeezed not broken in guide groove 14.Whole rotation inlet valve is difficult for producing large vibrations in the running simultaneously, thus the noise that has produced when having reduced running, and also obtained prolongation the service life of whole rotation inlet valve.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
