Powder storage tank

Abstract

The invention relates to a powder storage tank. The powder storage tank comprises a tank body; the lower part of the tank body is conical; a feeding pipe is arranged at the upper part of the tank body; the tank body is provided with an upper cover; a respirator, a blowback air pocket component, an air and material separator and an air suction port are arranged on the upper cover; a screw conveyeris arranged at the lower end of the tank body; an arch breaking mechanism is arranged on the tank body and comprises a drive motor, a reduction gearbox, a bevel gear set, a transmission shaft and a stirrer in drive joint sequentially; the bevel gear set comprises a driving bevel gear and a driven bevel gear; the driving bevel gear is mounted at the outer end of a horizontally arranged output shaftof the reduction gearbox; the driven bevel gear is mounted at the upper end of the transmission shaft; the drive motor and the reduction gearbox are mounted at the external part of the tank body; theoutput shaft of the reduction gearbox penetrates through the tank body and is in rotary seal fit with the tank body; the stirrer comprises a stirring paddle, and the axis of the stirring paddle is vertically arranged; the stirring paddle is positioned a conical structure at the lower part of the tank body; and the lowest end of the stirring paddle extends to the conical opening of the conical structure. The powder storage tank is small in noise, high in arch breaking capacity and is suitable for material with poor fluidity and likely to absorb moisture for caking.

Description

technical field [0001] The invention relates to a powder storage tank. Background technique [0002] Powder storage tanks are often used in food, pharmaceutical, wine, beverage, dye and chemical industries. For example attached figure 1 Shown is a traditional powder storage tank, which includes a tank body 6, a feed pipe 1 fixed on the tank body 6, a respirator 2 with a pneumatic valve, a blowback air bag assembly 3, and a gas-material separation tank are installed on the upper cover. device 4, air suction port pneumatic butterfly valve 5, maintenance manhole 8 and material level gauge 7, tank body 6 is fixed on platform 10 through outrigger 9, screw conveyor 12 is provided at the lower end of tank body 6, and the exit of screw conveyor 12 The feed port is equipped with a pneumatic butterfly valve 13 and a feed port 14. The screw conveyor 12 is composed of a motor, a reducer, a bearing box, a screw conveying shaft, a feed pipe, an oil seal, a bearing with a seat, and a con...

AI Technical Summary

Problems solved by technology

[0003] It can be seen that the above-mentioned traditional powder storage tank is loaded and stored through negative pressure transportation. This device only stores and transports some materials that have good fluidity and are not easy to absorb moisture and agglomerate. For general fluidity and easy to absorb The storage of wet and agglomerated materials is prone to bridging phenomenon. The bottom material is evacuated, and the upper material bridging will no longer fall, so normal transportation cannot be realized.

[0004] In order to solve this problem in the traditional way, a pneumatic oscillator 12 is generally installed on the surface of the tank body 6, but there are many disadvantages in this way, one of which is that it will generate very large noise, form noise pollution, and affect the physical and mental health of nearby personnel; The 2nd, can cause damage to the junction of support leg 9 and platform 10, make bolt loose, the bolt hole wall crack on the platform; For heavily agglomerated materials, the effect is very small
