Sand warehouse for filling device

Abstract

A sand bunaker used in a filling device includes a body, a pipeline and a jet nozzle. The bottom part of the body is provided with a hole for holding sand; besides, a through hole is arranged on the wall of the body; the pipeline is fixed on the outer wall of the body and is suitable for being connected with a fluid source; the jet nozzle is arranged on location of the through hole and is arranged on the outer wall of the body; the jet nozzle is communicated with the pipeline; the inner cavity of the jet nozzle is communicated with the inner cavity of the body by the through hole, thereby jetting the fluid to the inner cavity of the body. The pipeline and the jet nozzle of the invention are arranged outside the body; the pipeline and the jet nozzle are mounted and changed from the outside of the body; thus being more simply arranged and more conveniently maintained; the pipeline and the jet nozzle can not be impacted or eroded by the materials in the body, thus prolonging the service life of the jet nozzle; simultaneously, the floating of the materials in the body can not be baffled, thereby being beneficial to successfully discharging the materials in the body.

Description

technical field [0001] The invention relates to a sand bin, in particular to a vertical sand bin used in mine filling equipment. Background technique [0002] The sand bin is widely used for the concentration or storage of tailings. The low-concentration tailings slurry is input from the top of the sand bin. After the tailings settle and concentrate in the sand bin, they are discharged through the sand discharge pipe at the bottom. The concentration and flow rate of the slurry discharge The stability of is often critical to production. [0003] In order to maintain the stability of slurry discharge, nozzles can be added at the bottom of the sand bin to spray high-pressure water or compressed air into the bin. In order to deliver high-pressure fluid to the nozzle, a pipeline is generally arranged in the chamber body, and the nozzle is fixed on the pipeline. Such as application number is 97112374.8 Chinese invention patent application (disclosure date is on December 23rd, 19...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art including the above-mentioned filling process and equipment, the nozzles are installed in the sand bin together with the ring pipe, so the ring pipe and the nozzle are easily impacted and corroded by the materials in the bin body. The service life is short, easy to be damaged, and the maintenance workload is heavy, and it also hinders the flow of materials in the warehouse

In addition, the replacement and maintenance of the ring pipe and nozzle need to enter the interior of the chamber, so it is very difficult
