Description

The boiler batch charger

Technical field:

The utility model designs a kind of batch charger, particularly a kind of boiler batch charger that boiler is heated with peanut shell, the alternative coal of wood chip.

Background technology:

At present, China's medium small boiler all adopts coal to make fuel, and the expense height consumes greatly, and is also very big to the influence of environment; Now, development along with society, peanut shell, stalk and the wood chip that produces on the agricultural abandoned gradually by people or directly burning, caused environmental pollution, these things also do not use on boiler, and main cause is that peanut shell, stalk and wood chip density are big, heat is few, form a pile easily, be unfavorable for burning, do not reach heat; Peanut shell, stalk and wood chip can be used on boiler, will change feeding mode, these things can fully be burnt, accomplish reusing of energy source, at present, China is domestic also not to have such batch charger, and peanut shell, stalk and wood chip are used on boiler, thereby, caused energy waste.

Summary of the invention:

The purpose of this utility model be exactly to provide a kind of can resource reutilization, expense is low, consume less, free from environmental pollution, boiler batch charger that peanut shell, stalk and wood chip can be used on boiler.

The purpose of this utility model is achieved in that a kind of boiler batch charger, it is characterized in that expecting the indoor agitator that has, an end that on the one side, connects charging aperture, the other end of charging aperture connects feed pipe, the upper end of feed pipe is connected with blower fan import on the blower fan by feed hose, discharging opening on the blower fan connects nozzle by the discharging flexible pipe, and blower fan is connected with motor.

Material of the present utility model chamber is connected with charging aperture by dividing plate, and charging aperture is " eight " font; The lower end of feed pipe connects the cleaning flashboard, and the position, intermediate portion connects wind material by-pass valve control, and the cleaning flashboard adopts steel plate to make, and is rectangle, and wind material by-pass valve control adopts steel plate to make, and is " L " shape; The nozzle rear end is a round steel, and front end is a horn mouth, and side has gathering sill within it; Feed hose and discharging flexible pipe are wired hose.

The utility model compared with prior art has the following advantages:

Expect the indoor agitator that has owing to adopted, an end that on the one side, connects charging aperture, the other end of charging aperture connects feed pipe, the upper end of feed pipe is connected with blower fan import on the blower fan by feed hose, discharging opening on the blower fan connects nozzle by the discharging flexible pipe, the version that blower fan is connected with motor, thereby:

1, used peanut shell, stalk and wood chip to act as a fuel, substituted coal boiler is heated, economic benefit height, greening and environmental protection;

2, according to mensuration, 1 ton of dried wood chip, peanut shell are equivalent to 0.93 ton of standard coal, reduced cost, with 5 tons of boiler 6 tons of coals every day, used in 1 year and calculated in 300 days, year can be saved 105.3 ten thousand yuan, has reduced carbon dioxide rotten naturally owing to peanut shell, stalk and wood chip and the burning generation simultaneously, and year can reduce by 1300 tons of carbon dioxide;

3, use blower fan to be used as power, the blast height, wearability is good; Blower fan has the oxygen of raising, fuel, and makes both well-mixed triple functions, simple in structure, high efficiency;

4, nozzle has the effect of burning, water conservancy diversion, flame spread, strengthens flame turbulent flow, radiant heat transfer effect, and burning mixes, and efficiency of combustion is higher than plain cylindrical furnace 9%.
