Unpowered natural powder discharging device

Abstract

The invention provides an unpowered natural powder discharging device. The unpowered natural powder discharging device comprises a discharging cone port arranged at the bottom of a storage bin and provided with a gate and is characterized in that the middle of the discharging cone port is connected with a bottom ring through transverse support wing plates arranged at intervals and then is connected with a middle ring and a top ring at intervals from bottom to top through vertical support rods arranged on an outer wall of the bottom ring at intervals, and a top cover is connected onto the top ring. The unpowered natural powder discharging device does not need any power when normally operates, can completely perform natural discharging by relying on self weight of materials, arch erecting probability is remarkably reduced, and the problem that an arch is blocked due to quick single-point contraction in the prior art is solved thoroughly. The unpowered natural powder discharging device is simple and exquisite in structure and quick and convenient to install and maintain, and achieves quantitative blanking of power materials.

Description

technical field [0001] The invention relates to an unpowered unloading device in an industrial powder production system, in particular to various unpowered natural flow unloading cones for various powders. Background technique [0002] In industrial production, it is often necessary to quantitatively transport powdery materials stored in large warehouses, and its quantitative control quality is often a key link that affects the quality of its subsequent process products. However, when the powder is naturally discharged from the ordinary large storage bin, it will inevitably encounter the situation of arching and blocking in the bin mouth, forming a funnel discharge, resulting in an hourglass bottleneck type of flow-limiting and insufficient material or simply completely blocked and cut-off . The fundamental reason is that the powder above the outlet at the bottom of the warehouse will form a high-density ring-shaped arch ring due to simultaneous shrinkage and extrusion towa...

Problems solved by technology

Today, as the scale of production is expanding, this problem seriously restricts the stable realization of the flow rate required by the process, which in turn seriously affects the improvement of the corresponding process quality and efficiency.

[0003]At present, some enterprises choose the natural unloading scheme of ordinary bare silo with low investment, and can only adopt the method of artificial silo wall beating to remove blockage and unload, passively obtaining extremely unstable When the unloading of materials is blocked, most of them can only deal with the symptoms by repeatedly adopting the method of vibrating and knocking on the warehouse wall, but not the root cause. As a result, the process cost is greatly increased due to the poor stability of the process flow; some enterprises choose large investment The special multi-compartment fan type (such as 6-8 partitions) structure large warehouse, the air chute array is laid on the bottom of each warehouse, and the high-pressure air blows multiple large warehouses and transfers them to the middle small buffer warehouse to form the whole warehouse after suspension and homogenization density. Quantitative control is carried out through liquid compound gate valve opening adjustment. This full gasification scheme is theoretically feasible, but the overall structure is huge and complex, not only expensive, but also difficult to construct, labor-intensive, time-consuming and material-intensive, and consumes a lot of electricity during operation. High-pressure air supply, the result may not be able to achieve the expected effect, common in the new rotary kiln production line of more than 2000 tons / day key raw material powder into the kiln quantity control process

For the proportioning quantitative control process, general enterprises choose the semi-gasification scheme invested in China, directly laying an air chute array at the bottom of the large monomer reservoir, blowing out at a single point, and then adjusting the opening of the liquid compound gate valve to add various metering methods ( For closed-loop quantitative control such as punching scales, belt scales, or rotor scales), since the stable buffer chamber is omitted, although the investment has dropped significantly, the pressure density of the powder has increased, and its control effect has also dropped significantly, which is common in medium and large scales. Blending process of cement enterprises

[0004]All of these, the quantitative discharge control of the powder makes the majority of enterprises face the embarrassing situation of low or high difficulty, which seriously restricts the production process of industrial powder quality and efficiency
