Description

Technical field:

[0001] The utility model relates to the technical field of mortar nozzles, in particular to a mortar nozzle device for filling a sand bin. Background technology:

[0002] The graded tailings cementation filling technology is a commonly used filling technology in the filling mining method. At present, the filling process mainly uses a vertical sand bin to dehydrate and store the tailings slurry. The saturated tailings slurry is stored at the bottom of the sand bin and is used when filling. During filling, the tailings slurry flows into the stirring device through the sand discharge pipe at the bottom of the sand bin. In order to make the mortar at the bottom of the sand bin fluidized, a high-pressure water annular pipeline needs to be arranged at the bottom of the sand bin, and slurry is made through the slurry making nozzle at the bottom of the sand bin, so that the mortar at the bottom of the sand bin is loosened and fluidized, so as to flow out of the sand bin smoothly. At present, the nozzle used in the vertical sand bin can only spray along the central axis of the nozzle, the spraying range is small, and the working efficiency is low. At the same time, a one-way stop valve with an elastic telescopic sealing ball structure is used inside the nozzle for switching. When the stop valve is closed, the tailings slurry is sucked into the nozzle along the spray hole. After a period of use, the external space of the tailings slurry one-way stop valve is filled, which will cause the nozzle to be blocked, and the one-way stop valve cannot be opened again. The service life of the nozzle is short and needs to be improved urgently. Utility model content:

[0006] Furthermore, a blind hole is opened at the end of the first sealing rod, and a pressure spring and the sealing ball are installed in sequence from the bottom to the opening of the blind hole.

[0007] Furthermore, a rolling track matching the position of the radial spray hole is vertically opened on the inner wall of the outer cylinder cover, and the sealing ball rolls up and down in the rolling track.

[0008] Furthermore, the axial spray hole plugging assembly includes a second sealing rod vertically mounted on the first sealing rod, the second sealing rod is inserted into the axial spray hole, and a funnel-shaped sealing plug is connected to the top end of the second sealing rod.
