In the cage bone device for sack cleaner, the Venturi tube includes reducing pipe, trunnion and diffuser；
Several columns ventilation hole is circumferentially angularly offered on the side wall of the reducing pipe, trunnion and diffuser respectively.
In the cage bone device for sack cleaner, each ventilation openings of each row is in the vertical direction equidistantly
Arrangement.
In the cage bone device for sack cleaner, each ventilation hole is circular hole.
In the cage bone device for sack cleaner, each ventilation hole is rectangular opening.
In the cage bone device for sack cleaner, two sides are long side to each rectangular opening in the horizontal direction.
In the cage bone device for sack cleaner, there are one acute angles for axis and the horizontal plane tool of each ventilation hole
Angle.
In the cage bone device for sack cleaner, the axis of each ventilation hole and the angle of horizontal plane be 30 °-
60°。
Advantageous effect：
The utility model provides a kind of cage bone device for sack cleaner, by being opened on the side wall of Venturi tube
If several ventilation holes so that be improved using the filter bag effective area of the sack cleaner of the cage bone device, also improve into
The ash-removal effect of filter bag epimere during row pulse jet, in addition, extending cage to the impact force of cage bone when also reducing pulse jet
The service life of bone.
Description of the drawings
Fig. 1 is the cage bone device structure diagram provided by the utility model for sack cleaner；It is illustrated as positive mistake
Filter.
Fig. 2 is the cage bone device structure diagram provided by the utility model for sack cleaner；It is illustrated as reversely spraying
It blows.
Fig. 3 be the cage bone device provided by the utility model for sack cleaner, the sectional view of ventilation opening.
Specific embodiment
The utility model provides a kind of cage bone device for sack cleaner, to make the purpose of this utility model, technology
Scheme and effect are clearer, clear and definite, and the utility model is further described in the embodiment that develops simultaneously referring to the drawings.It should
Understand, specific embodiment described herein only to explain the utility model, is not used to limit the utility model.
It please refers to Fig.1 and Fig. 2, the utility model provides a kind of cage bone device for sack cleaner.It is only shown in figure
The epimere of cage bone and filter bag.Arrow show airflow direction in figure.
The cage bone device for sack cleaner including cage bone 10, is arranged on the installing plate 20 on cage bone top, with
And Venturi tube 30；The input end of the Venturi tube is set there are one flange 40, and Venturi tube is inserted into cage bone cavity and passes through institute
It is detachably connected with installing plate to state flange；Several ventilation holes 301 are offered on the side wall of Venturi tube.When by the cage bone
When device is applied in impulse bag filter, the actual card for deduster of above-mentioned installing plate, i.e. each card hole is accordingly
Cage bone there are one setting.
As depicted in figs. 1 and 2, in the cage bone device for sack cleaner, the Venturi tube is from input end
Include reducing pipe, trunnion and diffuser successively to the port of export；On the side wall of the reducing pipe, trunnion and diffuser respectively circumferentially
Angularly offer several columns ventilation hole.
Further, in the cage bone device for sack cleaner, each ventilation opening of each row is in vertical side
Upwards equidistantly.
Further, in the cage bone device for sack cleaner, each ventilation hole is circular hole.
Further, in the cage bone device for sack cleaner, each ventilation hole is rectangular opening.
Further, in the cage bone device for sack cleaner, each rectangular opening two in the horizontal direction
While it is long side.
Referring to Fig. 3, it is the sectional view on the vertical direction of ventilation hole shown in figure.Further, it is described to be used for bag
The cage bone device of formula deduster, there are one acute angles for axis and the horizontal plane tool of each ventilation hole.Foregoing circular hole or rectangle
Hole can obliquely be set by this scheme.
The right side of ventilation hole shown in Fig. 3 is venturi conduit inner cavity.In other words, the lower end of each ventilation hole is located at text
The outer wall of venturi, the higher-end of ventilation hole are located at the inner wall of Venturi tube.
Preferably, the cage bone device for sack cleaner, the axis of each ventilation hole and the angle of horizontal plane
For 30 ° -60 °.
Referring to Fig. 1, when application has the bag filter of foregoing cage bone device when carrying out forward filter；Due to venturi
Ventilation hole is offered on pipe side wall, thus can cause pending gas directly by 50 epimere of filter bag i.e. short transverse with text
Corresponding that section of filter bag of venturi）And pass through ventilation hole and enter in Venturi tube；I.e., compared with prior art, filter bag epimere into
For effective filter area, therefore improve filter effect and efficiency.
Referring to Fig. 2, when application has the bag filter of foregoing cage bone device when carrying out pulse jetting deashing, compression is empty
Gas enters the inside of Venturi tube from the centre position of the input end of Venturi tube, and causes the sky of Venturi tube inlet ambient
Gas finally sprays into filter bag 50 after being also drawn into Venturi tube and the mixing of aforementioned compression air so that filter bag generates impulsive inflation and shakes
It is dynamic, realize deashing.
Due to offering several ventilation holes on the side wall of Venturi tube, there is a few portion into the compressed air after Venturi tube
Divide the epimere for spraying to impact filter bag from each ventilation hole, so as to improve the ash-removal effect of filter bag upper end, simultaneously as one
Partial shrinkage air flow is sprayed from ventilation hole, therefore reduces impact of the compressed air to cage bone, improves the use of cage bone
Service life.
By obliquely setting ventilation hole as shown in Figure 3, guiding role is played, either compressed air is divulged information from ejection
Gas behind hole or filtering enters ventilation hole, and generated pressure loss is all reduced.
In conclusion the utility model provides a kind of cage bone device for sack cleaner, by Venturi tube
Several ventilation holes are opened up on side wall so that it is improved using the filter bag effective area of the sack cleaner of the cage bone device,
The ash-removal effect of filter bag epimere when carrying out pulse jet is improved, in addition, to the impact force of cage bone when also reducing pulse jet,
Extend the service life of cage bone.Further, by obliquely opening up ventilation hole, when reducing compressed gas ejection ventilation hole
The pressure loss, also reduce the pressure loss when gas after filtering enters ventilation hole.：
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and
The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement should all belong to appended by the utility model
