Description
(1) skill is stated the field
The utility model relates to a kind of apparatus for feeding of vapourizing furnace, a kind of specifically large-scale stalk gasifier automatic feeder.
(2) background technology
Energy shortage, environmental pollution have been the focuses of current social concerns.Phenomenon at rural area crop straw burning and the old-fashioned wood stove of use exists already, and annual giving discharged a large amount of dust and Wen Shi gas.At present the biomass energy waste mainly is an agricultural waste material, annual about 700,000,000 tons, can be used as about 300,000,000 tons of energy purposes, and amount to 1.5 hundred million tons of standard coals approximately.The suitable 300,000,000 tons of standard coals of forestry and wood working waste.Ground zero is gone back in popularization at the rural area miniature stalk gasification furnace.During use, to the requirement of fuel, use and result of use are also accepted unlike the masses.Problem mainly contains: 1, fuel must be through pulverizing manual time-consuming taking a lot of work, the problem that the mechanical disintegration cost is too high pulverized of its existence; 2, the moisture content to fuel has requirement, and general moisture content will be more than 25%, and this summer is not bad, but can't reach in the winter time at all; When 3, using must from get the raw materials ready, feed in raw material, igniting, on fire, use, the slagging-off several links, one goes on foot and can not lack, and brings many fiber crops numerous to the peasant; 4, small evaporator stove tar easy plugging road and switch in use, there is emission of bad smell etc. the time spent, and because the user of bogey relatively disperses, it used the waste residue that produced, the unrest of tar water, caused secondary pollution simultaneously.Large-scale vapourizing furnace in the market, need left alone without help machine when reinforced, can not continuous uninterrupted work, this is because need open the loam cake of vapourizing furnace during secondary charging, at this moment also have a large amount of combustion gas in the stove, and temperature is more than 300 ℃, the high-temperature fuel gas body is having under the situation of pressure and airborne combination with oxygen, be easy to blast, the CO concentration the when workman opens bell in the body of heater is easy to meet accident 20%.
(3) utility model content
It is a kind of simple and reasonable for structure that the purpose of this utility model is to provide, and just need not shut down and can feed in raw material, but non-stop run, and a kind of large-scale stalk gasifier automatic feeder of operational safety.For achieving the above object, the utility model is to be that the vapourizing furnace lower part of frame is a Rotary-table for right cylinder top, be provided with in the vapourizing furnace housing and smash the material pawl, the self-skimming device is arranged at the intravital bottom of vapourizing furnace shell, on Rotary-table side, vapourizing furnace housing top, have a feed port, it is the material feeding box of cone for the right cylinder bottom that a top is housed on the feed port, between vapourizing furnace housing and material feeding box, be provided with plate, plate all has gasket up and down, on the top of material feeding box, be provided with the charging case lid, the vapourizing furnace loam cake is arranged on the top of vapourizing furnace housing, on the another side of vapourizing furnace housing top Rotary-table an escape pipe is arranged, the vapourizing furnace housing bottom is provided with slag trapping box.Advantage of the present utility model is simple and reasonable for structure, and operational safety is reinforced convenient, but non-stop run.Close the plate between material feeding box and vapourizing furnace during charging, material feeding box and vapourizing furnace body of heater are completely cut off, therefore do not influence the operating pressure in the stove; Material feeding box is closed the material feeding box loam cake after filling it up with material, opens plate, forms a communicating vessels in material feeding box and the body of heater, and fuel is flowed in the stove, so just can not cause being mixed with a large amount of air in the stove, thereby significantly reduce danger coefficient.The vapourizing furnace of the one-stop central gas supply in its particularly suitable one village is promoted the use of, and also can use in the automatic feed field of industrial coal stove simultaneously.

(5) embodiment
Below in conjunction with embodiment the utility model is described in further detail:
The utility model is that the vapourizing furnace lower part of frame is a Rotary-table for right cylinder top, be provided with in the vapourizing furnace housing (4) and smash material pawl (7), vapourizing furnace housing (4) inner bottom part has deslagging device (5), on the Rotary-table side on vapourizing furnace housing (4) top, have a feed port, it is the material feeding box (1) of cone for the right cylinder bottom that a top is housed on the feed port, between vapourizing furnace housing (4) and material feeding box (1), be provided with plate (3), plate (3) all has gasket up and down, on the top of material feeding box (1), be provided with charging case lid (2), vapourizing furnace housing (4) also has vapourizing furnace loam cake (9) on the top, on the another side of vapourizing furnace housing (4) top Rotary-table an escape pipe (8) is arranged, slag trapping box (6) is arranged at vapourizing furnace housing (4) bottom.
Working when vapourizing furnace needs when reinforced, and first closes the plate (3) under the material feeding box (1), opens material feeding box loam cake (2), fills it up with to close the material feeding box loam cake behind the material to make material feeding box () be sweet envelope state.Second opens material feeding box (1) lower end plate (3) flows into fuel automatically, opens simultaneously to smash and expects that pawl (7) flows in the vapourizing furnace fuel uniformly.The 3rd plate (3) of closing the material feeding box lower end is finished fill process.
