Problems solved by technology

This method is labor-intensive and likely to endanger the safety of employees
[0005] 2. Mechanical vibrator, this kind of machine only works on the shed arch. If the coal or material is stored for a long time or the viscosity of the coal is high, it will vibrate more and more solidly, which will bring more difficulties to loosening
[0006] 3. Compressed air arch breaking device, this method consumes a lot of air, and the one-time investment is large, and coal or materials with high moisture content can only be more and more solid
[0007] 4. Lay the polymer anti-wear plate, this method needs to constantly replace the anti-wear plate, and the investment will increase

Embodiment 1

[0034] A set of arch-breaking rotating shafts is installed at the outlet of the warehouse body. It is suitable for all kinds of silos with small silo body and not serious arching.

Embodiment 2

[0036] Two sets of arch-breaking rotating shafts are installed symmetrically at the outlet of the bin body. The device can work all the time to prevent the coal bunker or material bunker from arching or shed (canopy), or it can only work when arching occurs.

Embodiment 3

[0038] When the lateral size of the coal bunker is too large, install two sets of arch-breaking rotating shafts on the horizontal line at the same height of the bunker wall. A coal drop slope is formed between the exit of the coal bunker and the surface of the rolling gear row of the rotating shaft. The slope determines the amount of coal falling and the pressure on the bottom row of teeth.

Abstract

The material arch preventing and breaking device with rotating shaft used in storehouse includes one arch breaking rotation shaft horizontally set onto the wall of storehouse, arch breaking gears mounted via key slots onto the arch breaking rotation shaft in equal interval, one sealing unit comprising steel plate and sealing ring for the arch breaking rotation shaft, one motor connected through belt to the transmission mechanism of the arch breaking rotation shaft and one inside support. The present invention is set in different kinds of material storehouse for preventing and breaking material arch and making material flow fluently.

Description

technical field [0001] The invention relates to an anti-arch and breaking device for a silo, in particular to an anti-arch and breaking device for a silo provided with an arch-breaking rotating shaft. Background technique [0002] At present, coal bunkers in various coal-fired power plants and material bins in other fields have shed (canopy) coal or material arching to varying degrees, which affects the normal operation of equipment and reduces economic benefits. Coal or material falls in the bin by free gravity, and there is lateral pressure between the material and the bin body, friction on the wall and pressure on the bottom. When the particle size of the material is too large or too small, the viscosity is medium or high, and the humidity is high, the compaction force and cohesive force between the materials will be greater than the free gravity after a long storage time, which will inevitably produce shed (canopy) coal or material arching Phenomenon. [0003] The loos...
