Description

DEM (Dosatore Elettro Meccanico) DEM (Electro Mechanical Doser)

Dispositivo composto da più ruote dentate di varia misura, mosso da motore elettrico alimentato a corrente di rete, atto al dosaggio, al sollevamento ed alla normalizzazione dimensionale di biocombustibili solidi granulari (mais, pellet, etc) utilizzati per alimentare stufe, caldaie e caminetti sia per uso domestico che per uso industriale atti alla produzione di aria e/o acqua calda. Device composed of several toothed wheels of various sizes, driven by an electric motor powered by mains current, suitable for dosing, lifting and dimensional normalization of solid granular biofuels (corn, pellets, etc.) used to power stoves, boilers and fireplaces both for domestic and industrial use suitable for the production of air and / or hot water.

La combinazione tra dimensione e quantità delle ruote dentate insieme al tempo di rivoluzione delle stesse, determinano la quantità del biocombustibile solido trasferito dalla tramoggia (serbatoio) al bracere (crogiolo) e di conseguenza identificano la potenza calorica prodotta The combination of size and quantity of the toothed wheels together with their revolution time determine the quantity of solid biofuel transferred from the hopper (tank) to the brazier (crucible) and consequently identify the caloric power produced

La misura dei denti (spessore e diametro) insieme alla lama posta a traguardo superiore della fase di carico del combustibile, unitamente al percorso del combustibile (vedi tavola 1 ) determinano la normalizzazione dimensionale del combustibile solido il cui quantitativo viene così regolato con precisione The measurement of the teeth (thickness and diameter) together with the blade placed at the upper line of the fuel loading phase, together with the fuel path (see table 1) determine the dimensional normalization of the solid fuel whose quantity is thus precisely adjusted

II diametro delle ruote dentate determina inoltre la misura di sollevamento del combustibile rispetto al fondo del serbatoio (tramoggia) permettendo di dare le necessarie lunghezza ed inclinazione allo scivolo di caduta del combustibile. Note: Tramoggia = serbatorio del combustibile The diameter of the toothed wheels also determines the extent to which the fuel is lifted with respect to the bottom of the tank (hopper), allowing the necessary length and inclination to be given to the fuel chute. Notes: Hopper = fuel tank

Bracere o Crogiolo = contenitore dove avviene la combustione Bracere or Crucible = container where combustion takes place

Claims

DEM - Claims The device called DEM, following the dimensional normalization of the pellet which, although of constant diameter, is produced in various lengths, allows to regulate the quantity of fuel introduced into the boiler, which thus becomes constant and allows a more precise regulation. Having a constant flow of pellets it is consequently possible to feed continuously differently from what happens in almost all stoves and boilers currently produced, where the feeding takes place in pulses with alternating load and stop intervals, and therefore with even considerable variations in the temperatures produced. in the braziers due to the different ignition times of the bio - fuel used, These different operating temperatures do not allow a real control of the emissions, while with the DEM operated continuously, a regular and constant combustion is obtained, a consequent better heat output and a lower production of emissions. The continuous operation of the DEM also eliminates the noise typical of impulse loading (e.g. with auger) and decreases the consumption of electricity due to the continuous starting of the electric motor.
