Line briquetting

Description line for the production of fuel briquettes.

Prednaznachenie:

    The line is designed to manufacture fuel briquette type Pini Key, characterized by auger method pressing. Externally, the briquette is a tetrahedron with face 50mm. and hole along the axis of a technological nature. The length of the briquette 300mm., cutting briquette is made by the wheel of knives immediately after leaving the barrel the extruder. The line is constructed on the basis of the extruder EB-350 and drying complex AVM-065.

The raw materials and end product:

The extruder is designed to produce briquettes from sunflower husk, buckwheat, rice and sawdust. The output of the extruder from 350 kg/h to 500kg, depends on raw material. When processing tarsi solid wood and sunflower husk the performance obtained 500kg/h stable during the entire shift. Fraction feedstock must be 2-mm (mainly regarding sawdust) and humidity 4-8%. The density of a briquette goes kg/cubic meters by sawdust and about 1000 on other raw materials. The moisture content of the briquette 2.7% , while the ash content of about 0.5-0.8% dependence on raw materials. It should be added that the briquette is environmentally friendly fuel, and thus representing a great advantage over conventional coal briquette.

Requirement to the room:

  The placement of the line is performed along premises, due to the technological cycle. At the moment the line is mounted on square 250m.kV., 6m. to 42m. height ceiling m Equipment is placed along the wall in the following sequence: the heat source, the diffuser and the conveyor feeding the feedstock to a clothes dryer, clothes the drum, the main cyclone. Screw conveyor feeder dry raw material in the extruder, extruder, exhaust Tonel, reception Desk briquette. The ceiling height is determined by the height of the main cyclone equal to 6 m The room should be ventilated and equipped with fire extinguishing means. Considerable space will allow us to procure more raw materials, procure the briquette to the warehouse and, if necessary, to place additional equipment.

Requirements to the network:

Installed capacity of the equipment but. Consumed 50 kW.

1.The motor of the extruder - VT.

2. The heaters of the barrel of the extruder - 11kW.(included not constantly).

3. The motor of the feeder of the extruder is 1.5 kW.

4. The motor of conveyor feeder dry raw material dryers in the feeder of the extruder - 1.1 kW.

5. The engine rotary dispenser main cyclone - 1.1 kW.

6. The engine main cyclone - 18.5 kW.

7. The engine of the drying drum to 3.0 kW.

8. The engine Assembly line feed to the dryer drum - 1.1 kW.

9. The engine and exhaust ventilation extruder - 1.1 kW.

Specific electricity consumption for t Briquette - Okolow.

Completeness and the principle steps:

1. Heat: is a furnace this design, which ensures complete combustion of volatile hydrocarbons released during the combustion of wood, the important role played regeneration heated air going into the furnace. In conventional furnaces all it usually crashes in the pipe, which significantly affects the efficiency and therefore reduced consumption of firewood. Because the temperature inside the furnace reaches had. at full power (brick becomes white heat) the heat source is made completely made of fireclay bricks laid on the mortar. Fire door also Safarova fireclay ensuring its sustained operation at high temperatures; the door is sealed. In the furnace burns almost all what they are capable lit. In practice, this usually wood freshly felled trees including stumps, railroad ties, opielka, all it can be called waste from sawmills. You can burn all wet and rotten, but keep in mind that heat dissipation will be lower. Oven lights until ready to serve raw on drying not more than 30min. Thermal capacity of the furnace wt.

2. The vibrating table: for cleaning materials from abrasive and large particles.

3. The belt scraper: to feed raw materials for drying. Represents two parallel chains with scraper in the middle driven by sprocket through the chain of a motor-reducer. On the belt is installed the agitator, the essence of which the alignment layer raw materials providing the monotony supply of raw materials. Conveyor bottom part installed on the floor, where it begins its the path of the imported raw materials, and the top is installed on the diffuser.

4. Difusor: connects the heat source dryer, on top the neck has the top of the conveyor; raw materials fall from the conveyor to the horizontal grid inside of the cone with which the air flow raw material is injected into the drum. The inner channel of the diffuser lined with fireclay brick and serves as a spark arrestor. Through the outer channel the surrounding air through the Windows in the diffuser enters into the inner channel lowering the temperature of the flue gases to the optimum. Inside the diffuser installed thermocouple for temperature control.

5. Clothes dryer: inside has developed surface. The product must pass three times along the barrel. Each of the three (as pipe-in-pipe)channels have blades for pouring of the product. So the product is triple the length of the drum at constant Persiani. The drum is mounted on rubber rollers, which lead him in the rotation system-easy installation
