Abstract
The utility model discloses a backflow-prevention type swirler which comprises a tubular body. A cylindrical shell is disposed on the tubular body, and an interlayer seal cavity is formed between the tubular body and the cylindrical shell. A spiral partition piece is disposed in the interlayer seal cavity so that a spiral airflow passage is formed inside the interlayer seal cavity. A front end of the spiral airflow passage is communicated with a pressure air tube, and a rear end of the spiral airflow passage is communicated with a center hole of the tubular body. A material dropping pipe is disposed on a lower portion of the middle of the interlayer seal cavity, an outer end portion of the material dropping pipe is provided with an end cover, and an inner end of the material dropping pipe is communicated with the center hole of the tubular body. The backflow-prevention type swirler can add powder accelerators to a shotcrete machine, improves construction environment, reduces construction expenses and increases economic benefit. In addition, propulsion degrees of the powder accelerators can be monitored through the material dropping pipe, compactness of the powder accelerators can be increased through a cone-shaped center hole so that the powder accelerators can be effectively prevented from flowing back.
Description
Technical field
The utility model relates to a kind of cyclone, particularly relates to a kind of anti-return formula cyclone.
Background technology
Fast development along with road traffic construction and mineral products construction; Unit in charge of construction need excavate various tunnels; And the tunnel is increasingly high, and the supporting of tunnel top and reinforcing become the difficult point and the emphasis of construction; Particularly be difficult for smearing fast concrete, adopt manual work smear concrete take a lot of work, time-consuming, efficient is low.To this situation; People develop some concrete spraying machines, are prepared burden the cement according to certain proportioning that stirs, sand, stone compound by rotor, deliver to shower nozzle with compressed air through conveying pipeline; Add water again and be sprayed onto on the construction surface, realize the purpose of quick concrete strengthening.The accelerator of concrete spraying machine use at present all is a liquid, and smell is big, and also there is the high deficiency of cost in addition in work under bad environment, if adopt powder accelerator, inlet suction port can cause powder accelerator to reflux so, and then the influence construction.
The utility model content
The utility model technical problem to be solved is: overcome the deficiency of prior art, the anti-return formula cyclone that a kind of modern design is unique, simple in structure, easy to use, can prevent the powder accelerator backflow is provided.
The technical scheme of the utility model is: a kind of anti-return formula cyclone, contain tubular body, and said tubular body is provided with columniform shell; Form the interlayer annular seal space between the two; Be provided with spiral holly strip in the said interlayer annular seal space, make to form the spiral air flow passage in the interlayer annular seal space, the front end of said spiral air flow passage is communicated with tracheal pressure; The rear end of said spiral air flow passage is communicated with the centre bore of said tubular body; The middle lower portion of said interlayer annular seal space is provided with material blanking tube, and the outer end of this material blanking tube is provided with end cap, and its inner is communicated with the centre bore of said tubular body.
Said tubular body rear end is provided with the back joint.Said tracheal pressure is along the tangential direction setting of said spiral air flow passage, and the rear end of said spiral air flow passage tangentially is communicated with the centre bore of said tubular body.The centre bore of said tubular body is taper, and its point diameter is greater than the rear end diameter.
The beneficial effect of the utility model is:
1, the utility model can add powder accelerator to concrete sprayer, has improved construction environment, has reduced operating expenses, has improved economic benefit.
2, the utility model is provided with material blanking tube, and the outer end of this material blanking tube is provided with end cap, can monitor the propelling degree of powder accelerator, and in addition, the centre bore of tubular body is taper, increases the packing of powder accelerator, prevents that effectively powder accelerator from refluxing.
3, the utility model novel in design unique, simple in structure, easy to use, can prevent the powder accelerator backflow, it is applied widely, is easy to promotion and implementation, has good economic benefit.
Description of drawings
Fig. 1 is the structural representation of anti-return formula cyclone;
Fig. 2 is an A-A cutaway view Amplified image among Fig. 1;
Fig. 3 is a B-B cutaway view Amplified image among Fig. 1.
The specific embodiment
Embodiment: referring to Fig. 1-Fig. 3, among the figure, 1-tubular body, 2-tracheal pressure, 3-shell, the holly strip of 4-spiral, 5-spiral air flow passage, joint behind the 6-, 7-material blanking tube, 8 – end caps, 9-air inlet.
Anti-return formula cyclone contains tubular body 1; Wherein: tubular body 1 is provided with columniform shell 3, forms the interlayer annular seal space between the two, is provided with spiral holly strip 4 in the interlayer annular seal space; Make and form spiral air flow passage 5 in the interlayer annular seal space; The front end of spiral air flow passage 5 is communicated with tracheal pressure 2, and the rear end of spiral air flow passage 5 is communicated with (air inlet 9) with the centre bore of tubular body 1, and the middle lower portion of interlayer annular seal space is provided with material blanking tube 7; The outer end of this material blanking tube 7 is provided with end cap 8, and its inner is communicated with the centre bore of tubular body 1.
During use, tubular body 1 front end is connected with the tail end of spiral propeller, and its rear end is connected with conveying pipeline, and tracheal pressure 2 is communicated with the external pressure source of the gas.Powder accelerator gets into through spiral propeller in the centre bore of tubular body 1, and when powder accelerator reaches material blanking tube 7 (this moment, end cap 8 was opened), powder accelerator will fall from material blanking tube 7; Cover end cap 8; The opening pressure source of the gas, pressed gas gets into spiral air flow passage 5 through tracheal pressure 2, through getting into the centre bore of tubular body 1 behind the eddy flow again; Blowing powder accelerator travels forward in conveying pipeline; Get at last in the shower nozzle of concrete sprayer, powder accelerator mixes with concrete mixture in the shower nozzle, is sprayed on the tunnel wall by concrete sprayer then.
The above only is the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction, and every any simple modification of doing according to the technical spirit of the utility model all still belongs in the scope of the utility model technical scheme.
