In general, the longer the storage time is, the stronger the compactness of the material, the increase of the internal humidity and the poor fluidity of the material, the more easily the arch is formed. Therefore, we should reduce the jumbo food storage bags silos time of the storehouse to a certain extent, at the same time, the jumbo food storage bags silos of the storehouse should be reasonable.

There are many factors in the knot arch, the main factors are three points: the long storage time, the increase of the moisture and the mass of the material, the adhesion of the material to the wall, the structure of the silo, which causes the material to be unable to circulate smoothly, and the part will be arch because the pressure is too large.

Due to the adhesion between the material and the wall, the material adheres to the inner wall of the bunker, resulting in arch formation. At present, ultra high molecular weight polyethylene plate (LHMWPE) is used as the lining of the silo, and its excellent mechanical properties are used to reduce the resistance between the material and the inner surface of the silo so as to play the role of anti arch.

The main types of the jumbo food storage bags silos are: one 'compressed arch, that is, because the powder is affected by the pressure, the consolidation strength increases and the knot arch is caused; two, the wedge arch, and the granular material is meshed with each other to reach the force balance state.

Bonded arch, cohesive material under water, moisture or electrostatic effect, and enhance the material and wall adhesion force formed by the material arch.

The air pressure balancing arch and the rotary unloading device of the bin cause air to flow into the silo due to poor air tightness, and the material arch formed when the upper and lower air pressure reaches equilibrium.

There is an essential difference between the arch and the arch. The purpose of the arch prevention is to prevent the arch. The aim is to eliminate or weaken the pressure on the vertical surface of the material arch, reduce the friction between the material, the material and the wall, and improve the fluidity of the material. The broken arch is studied after the arch, how to break, mainly by external force to break the arch from the mechanical point of view.

The principle of arch breaking is mainly to make the wall vibration and make the material move. Some use the air force to destroy the formation of the arch. In use, we should pay attention to the action of the broken arch device and the unloading action at the same time. The broken arch device can play a certain role in breaking the arch, but it can only act as an auxiliary measure. Therefore, I personally think that the significance of studying arch protection technology is greater than that of broken arch technology.

The material that changes the inner wall of the jumbo food storage bags silos can effectively prevent the arch, because the more smooth the material of the inner wall of the silo, the smaller the friction between the bin and the storehouse, so that the more easy they will flow and, to a certain extent, restrain the knot arch. Therefore, we should try to choose materials with smaller friction factor as the inner wall of the silos under the premise of meeting the strength.

At present, ultra high molecular weight polyethylene plate (LHMWPE) is usually used as the lining of the silo, and its excellent mechanical properties are used to reduce the sliding resistance between the material and the surface of the silo so as to play the role of anti arch.

In the production scheduling, the storage of the material and the storehouse is properly mastered and the storage of the material is arranged. The storage time of the material is not too long, and the arch is compressed and the material can not be unloaded.

Improving the shape of the conical discharge can effectively reduce the pressure between the silo and the silo wall, thereby reducing the friction between them. The method can also be used as a surface modification method.

From the angle of the cross section shrinkage of each part of the bucket, the profile of the longitudinal section of the bucket has a certain influence on the flow state of coal. For flat wall bunker, the inclination is generally fixed, the closer the contraction rate is, the more stress is gathered, so the easier the arch is. The wall of the hyperbolic silo is an equal section shrinkage, and the change of the wall is the track of the exponential curve.

The wall angle is changed. The closer the outlet angle is, the more the coal in the process of falling flow, the resistance is basically the same, thus the uniform continuous flow can be formed, and it is not easy to arch. Practice has proved that hyperbolic silos can effectively prevent arching.

In addition, it is called the nose shape warehouse, it is a special shape of the silo, its storehouse protruding like a "nose", it can disperse the pressure of the material, and the "nose" underneath the material into a loose state. The silo wall below the nose tip is subjected to high pressure and must be thickened. Otherwise, it will burst.

For the jumbo food storage bags silos, the fluid is usually added to the middle and lower part of the hopper. Its function is to improve the flow pattern of the powder in the hopper and reduce the pressure on the outlet of the material bin. The fluid can be a horizontal baffle, a vertical baffle or an inclined baffle.

Due to the formation of a material pile above the horizontal baffle, the time is easy to deteriorate the caking. In order to prevent this situation from happening, the baffle is made into a cone, which is the constant pressure cone. The lower part of the pressure cone will form an annular space, which can reduce the pressure of the material. The vertical and inclined baffles can eliminate the transverse pressure between some materials, and the material is divided into several streams, and the friction and shear forces between them are reduced.

The installation and fixing method of the embedded body can be hung on the crossbeam on the upper part of the bunker by a wire rope or fixed on the inclined wall of the funnel by three legs. This method is only applicable to shallow barn. To ensure sufficient inclination angle at the bottom of the bin and appropriately increase the inclination angle of the bottom of the bin is conducive to the smooth discharge of the silo.

However, if the silo is too steep and the sticky outlet is located on the side of the silo, it can at least reduce the knot arch force produced on one side because of the partial side configuration of the outlet, thus reducing the possibility of the knot arch, making the export material more loose and conducive to the discharge. For larger capacity silos, 2 or more than 2 outlets can be set up.
