Abstract
The utility model relates to smelting sintering equipment, in particular to a controllable hot-blast air recycling sintering machine. The controllable hot-blast air recycling sintering machine comprises a sintering machine body. A plurality of air inlets are formed in the side wall of the sintering machine body. An air induced cover for collecting hot-blast air is arranged in a discharging outlet in the sintering machine body. The air inlets comprise natural air inlets and hot-blast air inlets. The natural air inlets are connected with a cold-blast air blower. The hot-blast air inlets are connected with a hot-blast air blower. The hot-blast air blower is connected with a hot-blast air return pipe. The hot-blast air return pipe is connected with the hot-blast air induced cover arranged in the discharging outlet. An adjusting damper is arranged at the position of each hot-blast air inlet. According to the controllable hot-blast air recycling sintering machine, the production quality and efficiency can be improved, the whole structure is simple, energy is saved, and the operation and maintenance of the equipment are convenient.
Description
Technical field
The utility model relates to smelting agglomerating plant, specifically a kind of controlled sirocco reclamation sintering machine.
Background technology
In sintering technology field, hot gas sintering is an important energy-conserving and environment-protective technology, and it is for energy-conservation, the Yield and quality that improves sintering deposit has great importance, the general thermal flue gas back that adopts is received, and by using the waste gas producing to introduce once again combustion chamber, is conducive to energy-saving and emission-reduction.But be generally in this type of hot blast, contain a large amount of coal gas or incendivity dust, in metal recovery sintering, because the combustible that the flue gas after sintering contains is less, be unsuitable for the recovery of hot flue gas, therefore at metal slag charge, in the purification of chemical spent material, the hot gas after sintering just by dust process, outer row after cooling processing.Making does not have hot blast feeding in sintering machine, has reduced the production efficiency of sintering machine, has increased the cost of material of sintering machine simultaneously yet.
Summary of the invention
The purpose of this utility model, is exactly the problem existing for solving prior art, and has designed a kind of controlled sirocco reclamation sintering machine, can reclaim the heat of discharging opening, and adjustable to hot blast air quantity.
The technical solution of the utility model is: a kind of controlled sirocco reclamation sintering machine, comprise sintering machine, and the sidewall of sintering machine is provided with several air inlets, and the discharging opening of described sintering machine is provided with the blower cover that hot gas is collected; Described air inlet comprises natural wind air inlet and hot air inlet; Described natural wind air inlet is connected with cold blower, and described hot air inlet is connected with hot air blower, and described hot air blower connects hot blast return pipe; Hot blast return pipe is connected with the hot blast blower cover that is arranged on discharging opening; Described hot air inlet place is provided with damper.
The outside of described sintering machine is provided with cooling jacket cycling mechanism.
The outer end of described air inlet is connected with air blast by adpting flange.
The connection seam crossing of described adpting flange is provided with sealing ring, and adpting flange is bolted.
The blower cover of described hot blast return pipe and discharging opening welds together.
Described air door is Spile-type air door.
The beneficial effects of the utility model can draw by such scheme: owing to being provided with the blower cover of hot gas collection at discharging opening, can make full use of the waste heat after sintering, and what directly use is hot air rather than flue dust, contain the sintering that more oxygen is conducive to sintering machine.And be provided with damper at hot air inlet place, can regulate separately the air inflow of each air inlet.Reach best sintering state, improve the quality of production and production efficiency.The utility model overall structure is simple, saves the energy, equipment operating and easy to maintenance.
As can be seen here, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
