Abstract
The utility model discloses a sealed feed bin used for an organic solid waste heat treatment device. The sealed feed bin used for the organic solid waste heat treatment device comprises a bin body which is in a vertical structure. A drive shaft is arranged at the position of the central axis of the bin body, and bearings are arranged at the upper end and at the lower end of the drive shaft in sleeved mode. An upper cover plate is arranged on the top of the bin body and provided with symmetrical vacancies which are used as feed inlets. A lower cover plate is arranged on the bottom of the bin body and provided with symmetrical vacancies which are used as feed outlets. The feed inlets and the feed outlets are located at staggered and corresponding positions. Valve plates are perpendicularly fixed on the drive shaft in the bin body. A detachable flexible sealing element is arranged on the edge of each valve plate, and the detachable flexible sealing elements are closely contacted with the inner wall of the bin body, the lower surface of the upper cover plate and the upper surface of the lower cover plate. The inside of the bin body is divided by the valve plates into four spaces with the same volume. The sealed feed bin used for the organic solid waste heat treatment device has the advantages of being simple in structure, good in sealing performance and small in driving force.
Description
Technical field
The utility model relates to a kind of feed bin that is sealed into for the organic solid castoff annealing device, is matched in organic solid castoff gasification furnace and incinerator and uses.
Background technology
At present, the heat treatment organic solid castoff mainly contains and burns and the gasification dual mode, and capital equipment is incinerator and gasification furnace.In general, incinerator and gasification furnace be strict sealing all, and the needed air capacity of burning process and gasification is all passed through special air inlet and introduced, and realizes the stable operation of incinerator and gasification furnace burning process and gasification by regulating intake.Therefore, the charging aperture blow-by has a strong impact on the even running of equipment.For incinerator, charging aperture blow-by meeting affects the burner hearth air-flow and distributes, and increases air leakage coefficient, causes combustion conditions unstable, reduces the thermal efficiency.The sealing requirements of gasification furnace is higher, for the updraft type gasification furnace, and the charging aperture blow-by meeting entrained air in the gas that causes gasifying, calorific value decrease; For down-draft type gasifying furnace, charging aperture blow-by meeting causes air inflow excessive, and it is excessive to burn, and carbon dioxide increases in the gasification gas, reduces gasification gas calorific value.
The Chinese patent Granted publication number is: CN202118934U, Granted publication day is that the utility model of 2012.01.18 discloses a kind of feed bin that is sealed into, and is a kind of feed arrangement that is matched in incinerator and biomass waste cracking furnace.Thisly be sealed into the charging aperture that feed bin comprises that hopper is connected with body of heater, it is characterized in that being provided with between hopper and feed opening a feed bin, this feed bin upper/lower terminal is respectively equipped with movable flashboard, alternately opens by two movable flashboards, realizes dosing and sealing function.The sealing feeding warehouse is intermittent feed arrangement, whenever finishes a charging, has a certain amount of inside and outside gas exchange, the problem that sealing is difficult to realize.
The utility model content
Content of the present utility model is to provide a kind of sealing effectiveness that can realize feeding warehouse, is used for the feed bin that is sealed into of organic solid castoff annealing device.
For realizing above purpose, the utility model has been taked following technical scheme: a kind of feed bin that is sealed into for the organic solid castoff annealing device, the warehouse that comprises vertical structure, driving shaft is established in position, described warehouse axis, and driving shaft upper and lower side cover has bearing, and the warehouse top is provided with upper cover plate, has symmetrical vacancy on the upper cover plate as charging aperture, the warehouse bottom is provided with lower cover, has symmetrical vacancy on the lower cover as discharging opening, and charging aperture and discharging opening are in staggered corresponding position; Mutually vertically be fixed with valve plate on the driving shaft in the warehouse, the edge of valve plate is provided with dismountable flexible seals, flexible seals and warehouse inwall, upper cover plate lower surface, lower cover upper surface close contact, valve plate will be divided into four spaces that volume is identical in the warehouse.
Driving shaft is intermittently driven according to the gasifier operation situation by motor or hydraulic pressure, and each rotational angle is 90 degree, and before and after driving shaft intermittently drove, valve plate all was in the marginal position of charging aperture.
The utility model compared with prior art has following advantage: have simple in structure, good seal performance, the advantage that driving force is little.
