AI Technical Summary
Biomass feed tends to clump, bridge, and arch in the silo, leading to feed blockage and uneven discharge. Existing silo structures cannot effectively solve this problem, especially during high-temperature pyrolysis, where continuous and stable feed is difficult to achieve.
A material silo device for preventing biomass bridging is designed, employing an anti-bridging component, including a drive component, an arm connecting plate, and a wrist connecting plate. The rotation and cooperation of these components change the cross-sectional area of the discharge port and disturb the material, thereby preventing bridging and controlling the discharge flow rate.
It enables continuous feeding of biomass materials, prevents silo blockage, ensures continuous operation of the biomass pyrolysis process, and reduces power consumption and maintenance difficulty.

TECHNICAL FIELD

[0002] At present, biomass cannot be effectively treated by conventional treatment methods, and is generally treated by incineration. However, this treatment method will cause more serious impact on the environment. Therefore, how to treat biomass is a problem to be solved. In the prior art, the biomass is treated by high-temperature pyrolysis, which is a good choice. However, the biomass needs to be scattered before feeding and subsequent treatment. This part of the material is soft material, which becomes more dense after compression. It is difficult to scatter and feed. The existing method generally directly crushes the material by mechanical force at the initial stage, and then disperses it by a distributor. This not only increases energy consumption, but also makes it difficult to achieve sealing at the feeding end, which cannot meet the requirements of efficient pyrolysis in the later stage.
[0003] Due to poor flowability of biomass, it is easy to form a bridge, arch and group in the bunker. The biomass stored in the bunker cannot be smoothly taken out, and the bunker cannot work normally. The commonly used bunker generally has the following types: 1. Fixed bunker, which is generally a conical fixed cylinder. After storing materials, the materials are discharged by self-flowing. It is only suitable for materials with good flowability, such as coal, small material sand, and food. It is not suitable for biomass. 2. The bottom of the bunker is a straight cylinder, and the bottom is covered with a spiral or chain plate. This bunker has many driving components, high power consumption, and cannot control the discharge flow of biomass. SUMMARY
