Description
Technical field
The utility model relates to one kind to prevent negative pressure plugging device in filling pipeline, belong to the conveying of metal mine filling pipeline
Equipment technical field.
Background technique
Currently, metal mine retrofilling be all made of the cementing self-flowing pastefill of high concentration crude tailings, underground filling pipe arrangement
When, normal requirement leading portion L-type stowing gradient numerical value is less than back segment.Due to subsurface environment complexity, filling pipeline is generally sharp
With existing roadway engineering, often results in leading portion L-type stowing gradient numerical value and be greater than back segment times line value, in the case, pipeline material
Slurry conveying forms negative pressuren zone in front and rear sections intersection, reduces crude tailings and conveys flow velocity, coarse granule sinks to being easy blocking filling pipe
Road causes pipeline jam accident, and influencing filling can not work normally, and causes to adopt and fills imbalance.To avoid such accident from occurring, before generally pressing
Section L-type stowing gradient numerical value is less than back segment requirement and digs new tunnel, digs new tunnel and not only increases developing cost, also shadow
Ring stope filling progress.Therefore, it is necessary to negative pressure plugging device in a kind of solution filling pipeline of innovative design.
Utility model content
The utility model aim, which is to provide one kind, prevents negative pressure plugging device in filling pipeline, can eliminate in filling pipeline
Negative pressure, avoid pipeline jam accident, solve the problems, such as background technique.
The technical solution of the utility model is:
One kind preventing negative pressure plugging device in filling pipeline, includes three-way pipeline, rubber stopper, spring, spring support, method
Blue, air inlet and air hole, the three-way pipeline include supervisor and be responsible for branch pipe connected vertically, the both ends point of the supervisor
Not She You flange, one end of branch pipe be connected to supervisor, and the other end of branch pipe is closed end, the closed end of branch pipe equipped with air inlet,
Rubber stopper and spring are equipped in branch pipe, the rubber stopper is located at the closed end of branch pipe, and rubber stopper is equipped with air hole.
One end of spring in the branch pipe is fixed on spring support, and spring support is fixed on supervisor, spring it is another
One end is withstood on rubber stopper.
Supervisor and branch pipe in the three-way pipeline are threadedly coupled.
The air hole on rubber stopper in the air inlet and branch pipe of the branch pipe closed end is staggered cloth along the center line of branch pipe
It sets.
Rubber stopper in the branch pipe is the cylinder matched with branch pipe, and air hole is to be located on rubber stopper center line
Through-hole.
The utility model is used, in use, by three-way pipeline by the flanged joint at supervisor both ends in fill line road
On, when being in negative pressure state in fill line road, outside air is downward by the air inlet on the branch pipe in three-way pipeline
Rubber stopper and compressed spring are pushed, partial air supplements the gas in three-way pipeline and filling pipeline by the air hole on rubber stopper
Body pressure, finally eliminates negative pressure state, avoids pipeline jam accident.
The beneficial effects of the utility model are: the negative pressure in filling pipeline can be eliminated, pipeline jam accident is avoided, is influenced
The normal operation of filling.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure: three-way pipeline 1, rubber stopper 2, spring 3, spring support 4, flange 5, air inlet 6, air hole 7, air chamber 8,
