Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment 1
As shown in Figure 1, present embodiments providing, a kind of continuous uniform is stable and the adjustable discharge valve of feed quantity, it includes shell
Body 1, impeller 2, blade 3, material chamber notch board 4, curved plate 5 and floor 6；1 inside up/down perforation of housing, in the top and the bottom of housing 1
Feed inlet 11 and discharge port 12 are respectively equipped with, cylindrical discharging chamber 13 is formed at the middle part of housing 1；Impeller 2 is along discharging chamber 13
Axis is rotatably arranged on inside it, along fixed 16 blades 3 in its circumferencial direction interval on impeller 2, per two neighboring blade 3 it
Between angle be 22.5 °, the free end of blade 3 is fully bonded with the inner wall of housing 1, fixed between each two adjacent blades 3
Material chamber notch board 4 is set, and the space between two adjacent blades 3 and material chamber notch board 4 forms material chamber 7；Below discharging chamber 13
12 both sides of discharge port are symmetrical arranged curved plate 5, and curved plate 5 is strengthened fixing by floor 6, make the inner wall of curved plate 5 with
The inner wall of discharging chamber 13 is tangent, and the radius of curved plate 5 is identical with the inner wall radius of discharging chamber 13, between two curved plates 5
A notch is formed, the size of the notch is identical with the size that material chamber 7 exports.
In above-described embodiment, upper end cover 14 and bottom end cover 15 are correspondingly arranged respectively in the top and the bottom of housing 1, with easy-unloading
The connection of valve and miscellaneous part.
The use process of the utility model is as follows：When discharge valve works, impeller 2, which rotates, drives material chamber 7 to rotate, housing 1
The material that feed inlet 11 constantly enters fills up the material chamber 7 connected with feed inlet 11, when the material chamber 7 for filling material is rotated with impeller
To discharge valve sidewall locations when, the material chamber 7 full of material separates the air pressure between feed inlet 11 and discharge port 12, makes discharge valve
With preferable sealing effect；When material chamber 7, which continues to rotate to the lower section of discharge valve with impeller 2, to be connected with discharge port 12,
Expect that the material in chamber 7 is discharged under the action of gravity and negative pressure through the notch between two curved plates 5, due to two curved plates 5
Between notch size it is identical with the outlet size for expecting chamber 7 so that each discharging quantity of the discharge port of discharge valve is a material chamber 7
Material, in such manner, it is possible to ensure that the discharging quantity continuous-stable of discharge valve is uniform, avoids the impact of discontinuously discharge material web.
In the case where 2 rotating speed of impeller is constant, in order to adjust the discharging quantity of discharge valve and discharging stability, tune can be passed through
The quantity of completeblade 3, the installation site of material chamber notch board 4, the notch size of curved plate 5 are realized, in embodiment 2 and embodiment 3
In be explained；
Embodiment 2
As shown in Fig. 2, the present embodiment is compared with Example 1, the blade laid on impeller 2 along its circumferencial direction interval becomes
For 12, the angle between two adjacent blades 3 is 30 °, fixes setting between the adjacent blade 3 of each two close to 2 outer wall of impeller
A material chamber notch board 4 is put, 7 volume of the material chamber increase formed between two adjacent blades 3 and material chamber notch board 4, the outlet size of material chamber 7
Increase, the notch size between two curved plates 5 also increases, and ensures the notch size between two curved plates 5 with expecting going out for chamber 7
Mouth size keeps identical, and the other structures of discharge valve are constant；So in the case where the rotating speed of impeller 2 is constant, ensure discharge valve
Discharging is uniform and stable while increases the discharging quantity of discharge valve, but due to the reduction of blade 3 and material 7 quantity of chamber so that discharge valve
Dense block gas effect is slightly worse than embodiment 1.
Embodiment 3
As shown in figure 3, the present embodiment is compared with Example 1, on impeller 2 and along the fixed blade in its circumferencial direction interval
Number is changed to 10, and the angle between each two adjacent blades 3 is 36 °, and material chamber notch board 4 is not provided between two adjacent blades 3,
Material chamber 7 is formed between two adjacent blades 3 and the outer wall of impeller 2, the volume and outlet size for expecting chamber 7 further increase, two arcs
The notch size of bottom plate 5 accordingly increases, and keeps identical with the outlet size for expecting chamber 7, discharge valve other structures are constant；In this way,
In the case that wheel speed is constant, the discharging quantity of discharge valve further increases, but discharge valve sealing effect further weakens.
It is of course also possible to the discharging quantity of the rotational speed regulation discharge valve by adjusting impeller 2, i.e., in above-mentioned each individually implementation
In example, the rotating speed by adjusting impeller 2 changes the discharging frequency of discharge valve to adjust the discharging quantity of discharge valve, but each to ensure
Material chamber 7 can fill up material, and 25r/min is not to be exceeded in the maximum speed of impeller 2.
The utility model is only illustrated with above-described embodiment, and structure, setting position and its connection of each component are all can
With what is be varied from.It is all that individual part is carried out according to the utility model principle on the basis of technical solutions of the utility model
Improvement or equivalents, should not exclude outside the scope of protection of the utility model.
