Raw material storage hopper: the device consists of an upper closing-in part, a bin body, a lower closing-in part and a discharge gate. The biomass direct combustion adopts continuous operation, and a raw material storage hopper has to be arranged, and has the following functions: storing and discharging raw materials, adjusting and buffering contradictions between the production of the biomass direct-fired system and the transportation of external raw materials, and ensuring the balanced and continuous production of raw material supply; the material conveying time is shortened, the material turnover rate is improved, and the passing capacity of the storage conveying system is increased. Therefore, the reasonable arrangement of the raw material storage hopper is an important measure for improving the production capacity of the direct combustion of the biomass and ensuring the normal production of the direct combustion of the biomass.
The parameters of the raw material storage hopper include the capacity, cross-sectional size and height of the hopper. The capacity of the hopper is determined according to factors such as the production capacity of direct combustion of biomass, the passing capacity of raw material production and transportation, the mechanization degree of raw material production and the like.
Because raw materials, granularity composition, the flow situation are different, in order to guarantee the safety in production, the raw materials storage hopper design must accomplish: the raw materials stored in the raw material storage hopper can be smoothly discharged by the gravity of the raw materials without the help of external force, and the raw materials are not accumulated, arch formation and bin blockage are avoided; the impact, abrasion and damage of the raw materials to the bin wall or the bin bottom can be prevented or reduced; the storage bin has large effective volume, few dead angles, high unloading mechanization degree and safe use, and is provided with facilities for preventing and controlling the faults of the storage bin; the storage bin has the advantages of less engineering quantity, good construction and maintenance conditions and less investment, and can meet the requirement of the biomass direct-fired service life.
Large inclination buried scraper conveyor: the conveying inclination angle can reach 0-90 degrees, so the device is particularly suitable for large-inclination conveying and can meet the conveying of biomass raw materials between different heights. The belt conveyor with the large inclination angle is novel continuous conveying equipment, and has large conveying capacity (compared with other conveyors, the conveying capacity is improved by 1.5-2 times); the universal belt conveyor has strong universality (the basic parts are the same as those of the universal belt conveyor), and the application range is wide (the universal belt conveyor is suitable for conveying materials such as broken stones, limestone, coal, sand, clay, sintered sand powder, wood chips, grains and the like); simple structure, convenient maintenance, small occupied space, investment saving, convenient arrangement and the like, thereby being widely popularized and used in the biomass application industry.
Horizontal scraper conveyor: the continuous conveying equipment is used for conveying bulk materials by means of a moving scraper chain in a closed rectangular section shell; when conveying materials, the scraper chain is totally embedded in the materials, so the scraper chain is called an embedded scraper conveyor. The product has the characteristics of simple structure, good sealing performance, convenience in installation and maintenance, flexible process arrangement and the like; the conveying can be horizontal conveying, and also can be inclined or vertical conveying; can be used by a single machine or by a plurality of machines; can feed materials at multiple points and can discharge materials at multiple points. Because the housing is closed, the working environment of workers can be remarkably improved and environmental pollution can be prevented when materials are conveyed. Can meet the requirement of conveying biomass raw materials at different distances.
The buried scraper conveyor has the following product characteristics: 1. are commonly used for horizontal transport of granular and powdery materials; 2. the device has the characteristics of long service life of the whole machine, stable operation, small structural size, large conveying capacity, low energy consumption, low material breakage rate and the like; 3. the whole machine structure is in a closed form, so that the environmental pollution is reduced when materials are conveyed; the conveying can be horizontal conveying, and also can be inclined or vertical conveying; can be used by a single machine or by a plurality of machines; can feed materials at multiple points and discharge materials at multiple points.
A furnace front hopper: the biomass direct combustion adopts continuous operation, the function of the biomass direct combustion system is a transfer station of fuel, a furnace front hopper is a key component of the biomass direct combustion system, and the material level is related to whether the biomass direct combustion system can stably and normally operate. The material level overflows due to overfilling, so that fuel waste accidents are caused; too low level or emptying can cause the accidents of unstable combustion and even fire extinguishing shutdown.
