Project design of straw demonstration county

Straw coal forming machine refers to a complete set of mechanized production equipment for straw carbon, which takes corn straw, wheat straw, cotton straw, rice straw, rice husk, peanut shell, corn cob, branches, leaves, sawdust and other crops and rural solid wastes as raw materials, and is crushed, pressurized and densified.

The straw briquette forming machine has good performance, high productivity and convenient operation and use. It is an environment-friendly and energy-saving product based on rural areas and utilizing biomass resources. It is a sunrise industry for farmers to turn waste into treasure and increase their income.

The application scope of straw coal forming machine "straw coal";

Straw coal can replace firewood, raw coal and liquefied gas. Widely used in household stoves, heating stoves, hot water boilers, industrial boilers, bio-gasification boilers in biomass power plants, etc. Straw coal is a new type of biomass renewable energy, which is environmentally friendly and clean, far lower than the cost and market price of raw coal, and is widely used. Heating in cities, hotels, restaurants, bathing and other industries has solved the problem that the use of coal-fired boilers does not meet the requirements of environmental protection, and solved the heavy operating pressure caused by the fuel cost being ten times higher than that of straw coal.

Characteristics of straw coal forming machine;

1. One-step molding, saving cost and high efficiency.

2. High degree of automation, high output, low price, low power consumption, simple operation and convenient movement. If there is no power equipment, a diesel engine can be used instead. ?

3. Strong material adaptability: it is suitable for the molding of various biomass raw materials, and the straw can be molded from powder to 60mm long with a moisture content of 5-30%.

4. Electric heating function: automatic electric heating device, which can adjust the dry humidity of materials and solve the problem of material blocking and non-forming.

5. Automatic adjustment function of the pressure roller: the pressure angle is automatically adjusted by using the principle of bidirectional rotation of the thrust bearing, so that the material is not crowded or stuffy, and the stability of discharging molding is ensured.

6. Simple operation, convenient use: high degree of automation, less labor, only three people, manual feeding or automatic feeding by conveyor.

7. Long service life of grinding disc: the mould is made of special steel and special wear-resistant materials, and it does not need to be replaced within three years.

8. Performance ratio and high cost performance: On the basis of similar equipment, the scientific and technological content and functions of this machine have been improved. In terms of price, the affordability of users, especially the processing cost of farmers' friends, is fully considered.

9. Process flow: crushing → transportation → compression molding → finished product warehousing.

Production and processing procedures of straw fuel molding machine: cut materials over 60mm with straw cutter or crush them with pulverizer, and the particle length and water content of the materials are within the specified range; The material is evenly delivered to the material port above the molding machine by a feeder (belt conveyor) or manually, and the finished product is obtained by press molding. From the source of raw materials to the use of fuel, the process is as follows: material recovery → chopping → automatic metal removal from feeding → pressing → molding → output → cooling → transportation → biomass power plant or small boiler or civil use.

The principle of solid briquetting JBM series straw briquetting machine uses the interaction principle of extrusion force between flat die and press wheel and friction force of die hole to shape materials. In the process of processing, there is no need to add any additives or adhesives to the material. Straw and other materials contain a certain amount of cellulose and lignin, which is a structural monomer in the material and a phenylpropane polymer compound. It has the functions of strengthening cell wall and binding cellulose. Lignin is amorphous, its main part is insoluble in any solvent at room temperature, and it has no melting point but only softening point. When the temperature reaches a certain value, the softening and cohesive force of lignin increases. Under a certain pressure, its cellulose molecular groups are dislocated, deformed and elongated, in which adjacent biomass particles mesh with each other and recombine to form briquettes.
