Fuel bricks factory - 1 ... 1,5 tons per hour on various raw materials
A full fuel briquettes factory, productivity 1 ... 1,5 tons per hour. Raw materials: any particulate, straw in rolls and bales, wood waste and pulpwood. Logs, slabwood and other woodwaste get into the chipping machine (18) by a transporter (19). From it the chips get on the transporter (20) and then to the mechanized storehouse “moving floor” (1). The straw in rolls gets to the transporter (22), then – to the chipper for the rolled straw (21). The chipped straw by a pneumatic transport gets to the mechanized storehouse “moving floor”. The raw materials in small particles is brought to the factory by automobile transport (or auto-loader) and is delivered to the mechanized storehouse “moving floor” (1). The stockers of the moving floor have a hydraulic engine which moves them in a reciprocating mode. The paddles (“wings”) of the stockers are wedge-shaped, that is why while they are moving the raw materials get to the chain (scraper) transporter (2) with a regulated speed, then the raw materials get to the disk separator (3). Here the raw materials are separated from the stones, roots and other impurities, which get into a transportable bin (not presented at the scheme), and the raw materials get by a gravity flow into the loading section of the Drying and Chipping Aggregate (4). Here the burning products are delivered from the heat generator (5) and cold atmosphere air through a special pipe (6) (not included into equipment list). At first the burning products are mixed with the cold air, the proportion is regulated automatically and this provides for a stable temperature of the heat transfer agent. Then the heat transfer agent is mixed with the wet raw materials and soaked into the Drying and Chipping Aggregate (4). In it the raw materials are chipped and then dried coming up in the flow of the heat transfer agent to the dynamic classifier which is situated in the heading part of the Drying and Chipping Aggregate. The dynamic classifier which frequency is set from a remote control (15) lets through small and dry particles and wet and big particles are sent back to the Aggregate rotor, where the process is repeated until the necessary condition of the material (details). Chipped and dried raw materials (from this moment it is common to call it flour) is soaked into a settling cyclone (8) due to the exhaustion provided by the exhauster. In the cyclone the flour is settled due to the centrifugal force and moves downwards, and the used heat transfer agent is exhausted through a chimney (16). From the cyclone the flour through a floodgate gets into a screw or a chain transporter (9), then to the bin of the briquetting press (10). Inside the bin there is a machine which prevents caking. From the bin the flour by a screw feeder with a regulated speed gets into the briquetting press (11). In the press the flour first gets into the areas of preliminary pressing and the by two opposite screw feeders to the pressing area. In the pressing area the flower is squeezed by a moving piston into a fixed cone matrix where under high pressure an unbroken brick is formed (hereinafter – brick). After the press the bricks have high temperature and are not strong enough that is why they are sent to the tunnel cooler (12). In the process of cooling the moisture content in the bricks is decreased due to evaporation and there are also physical and chemical changes in them. As a result they get the necessary characteristics on temperature, moisture content and hardness. Moving along the tunnel which is at the same time also a conveyor the unbroken brick goes through a metal detector (13) and gets into an automatic saw (14), where it is cut into the bricks of a certain length. Then the bricks get into a packing area and ready products storehouse (not presented). The heat generator in this particular set can be loaded manually (through the door) and automatically – from the fuel bin (7). The bin can be loaded automatically (optional) due to the fact that some flour comes back from the settling cyclone (8) by pneumatic transportation system (17). Optionally the fuel bin can be equipped by an extra conveyor from the raw materials storage or fuel storage (not presented).
