Abstract
A kind of nozzle ring structure of the utility model, including annular solid, multiple nozzle bores are circumferentially offered on the annular solid, the annular solid lower end is provided with U-shaped baffle, the U-shaped baffle and annular solid form sealing cavity configuration, and the U-shaped baffle lower part is also circumferentially arranged air admission hole.By the baffle set in nozzle ring ring body structurc lower part, will effectively be recycled into the dust of nozzle ring lower part so that dust can not enter in the abrasive disk seat that nozzle ring lower part is set; effectively protection abrasive disk seat; so that its service life is extended, energy conservation and environmental protection reduces the cost of enterprise.
Description
Technical field：
The utility model is related to mechanical equipment technical fields, and in particular to a kind of nozzle ring structure.
Background technology：
At present on the market common nozzle ring structure on crushing material production line in use, passing through the nozzle on nozzle ring
Structure blasts air to crushing material intracavitary, but often some material dust can with air from nozzle arrangements into
In the abrasive disk seat for entering the setting of nozzle ring lower part, abrasive disk seat is caused to wear and blocked, entire technique is impacted.
Therefore, it is necessary to a kind of nozzle ring structure that more disclosure satisfy that use demand is designed, to solve the above problems.
Utility model content：
The purpose of this utility model be to provide it is a kind of can by the nozzle ring structure that material dust recycles, stop dust into
Enter in abrasive disk seat.
To achieve the above object, the utility model uses following technical scheme：
A kind of nozzle ring structure provided by the utility model, circumferentially offers more including annular solid, on the annular solid
A nozzle bore, the annular solid lower end are provided with U-shaped baffle, and the U-shaped baffle and annular solid form sealing cavity configuration, the U
Shape baffle lower part is also circumferentially arranged air admission hole.
The nozzle bore upper end is obliquely installed towards the central axes of annular solid.
The base of the U-shaped baffle is horizontally disposed with, and the Upper vertical of U-shaped baffle is set, and its underpart is towards annular solid
Central axes are obliquely installed.
The air admission hole is vertically installed in the U-shaped baffle lower part.
A kind of advantageous effect of nozzle ring structure of the utility model：Pass through the gear set in nozzle ring ring body structurc lower part
Plate will effectively recycle so that dust can not enter the mill that nozzle ring lower part is set into the dust of nozzle ring lower part
In disk seat, abrasive disk seat is effectively protected so that its service life is extended, energy conservation and environmental protection, reduces the cost of enterprise.
Description of the drawings：
Fig. 1 is a kind of structure diagram of nozzle ring structure of the utility model；
Fig. 2 is the bottom view of Fig. 1；
1- annular solids, 2- nozzle bores, 3-U shape baffles, 4- air admission holes.
Specific embodiment：
With reference to embodiment, the utility model is described in further detail.
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that described embodiment is only the part of the embodiment rather than whole of the utility model
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise
Lower all other embodiments obtained, shall fall within the protection scope of the present invention.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute in the utility model embodiment
It is only used for explaining relative position relation, motion conditions under a certain particular pose (as shown in drawings) between each component etc., such as
When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.
In addition, the description of " first ", " second " etc. as involved in the utility model is only used for description purpose, and cannot manage
It solves to indicate or imply its relative importance or the implicit quantity for indicating indicated technical characteristic.Define as a result, " the
One ", at least one this feature can be expressed or be implicitly included to the feature of " second ".In addition, the skill between each embodiment
Art scheme can be combined with each other, but must can be implemented as basis with those of ordinary skill in the art, when technical solution
It will be understood that the combination of this technical solution is not present with reference to there is conflicting or can not realize when, also not in the utility model
It is required that protection domain within.
According to Fig. 1~Fig. 2, a kind of nozzle ring structure provided by the utility model, including annular solid 1, the annular
Multiple nozzle bores 2 are circumferentially offered on body 1,2 upper end of nozzle bore is obliquely installed towards the central axes of annular solid 1, is led to
Cross nozzle bore 2 penetrating air it is a part of vertically moving, another part is then being obliquely installed the influence of nozzle bore, direction
Annular solid center position moves, and 1 lower end of annular solid is provided with U-shaped baffle 3, and the U-shaped baffle 3 and annular solid 1 form close
Cavity configuration is sealed, 3 lower part of U-shaped baffle is also circumferentially arranged air admission hole 4.
Further, the base of the U-shaped baffle 3 is horizontally disposed with, and the Upper vertical of U-shaped baffle 3 is set, the equal court in its underpart
It is obliquely installed to the central axes of annular solid 1 so that 3 inside of U-shaped baffle forms an inverted round stage cavity structure, by the air admission hole
4 are vertically installed in 3 lower part of U-shaped baffle so that carry out both direction into the air in cavity structure by air admission hole 4
Shunting will effectively recycle so that dust can not enter what nozzle ring lower part was set into the dust of nozzle ring lower part
In abrasive disk seat.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model rather than it is limited
System, although the utility model is described in detail with reference to above-described embodiment, those of ordinary skill in the art should manage
Solution：Specific embodiment of the present utility model can be still modified or replaced equivalently, and without departing from the utility model
Any modification of spirit and scope or equivalent substitution should all cover among present claims scope.
