Double-cone powder bin and process method thereof

Abstract

The invention belongs to the technical field of powder storage equipment, and particularly relates to a double-cone powder bin and a process method thereof. The double-cone powder bin and the processmethod are characterized in that the double-cone powder bin comprises a bin body formed by an upper cone, a middle cylinder and double cones, a feed filter box, a dust collector, a 3D material level scanner, a feeding pipe and two sound wave ash removing devices, wherein the feed filter box, the dust collector and the 3D material level scanner are arranged on the upper cone, the feeding pipe is connected with the feed filter box and is arranged on the outer side wall of the middle cylinder, and the two sound wave ash removing devices are symmetrically arranged on the outer side walls of the double cones. The upper cone is arranged on the upper part of the middle cylinder, and the double cones are symmetrically arranged on the lower part of the middle cylinder. The double-cone powder bin solves the problems of a large number of powder bins and the large floor area, and realizes smooth self flowing discharging of powder and high-precision measurement of the real-time material level.

Problems solved by technology

[0002] At present, more and more large and super-large mines are exploited by the filling method, but the volume of the traditional powder silos used for filling and storing bulk cementitious materials is small, and all of them are powder silos with single bucket and single outlet. One powder silo can only correspond to one mixing system

At the same time, the filling station adopts redundant design, and a backup system must be built

These will inevitably lead to a large number of powder bins in the filling station and a large footprint

[0003] Secondly, the cementitious material in the powder silo is prone to deliquescence and hardening, resulting in blockage, suspension or poor feeding. At present, compressed air is often used to help flow and prevent blockage, and it is installed equidistantly on the wall of the cone at the bottom of the silo. Multiple nozzles form an air cushion, but the consumption of compressed air is large and dust is easily generated. The nozzles are easily damaged and require a lot of maintenance; or install a vibrator on the warehouse wall outside the warehouse, but the power consumption is large, and long-term vibrating may cause damage to the warehouse wall. Open welding or tearing, deformation, etc., increase maintenance

[0004] Furthermore, the material level of the powder silo is mostly measured by radar level gauges and weight level gauges based on the principle of single-point measurement, but the discharge accumulation of the cementitious material and its own characteristics present an irregular surface , the single-point measurement method is very unsatisfactory in actual use, and the error is relatively large; while the pressure sensor weighing measurement can reflect the remaining amount of materials in the warehouse, but it cannot show the gelled material in the warehouse. surface state, and need to change the warehouse body and basic structure, the investment is relatively large
