Abstract
The utility model discloses a secondary downdraught grate with non conveyor idler system, relating to a preheating grate of pellet drying, composed of a green pellet conveyer belt device, a roller sieve, a chain grate machine, a rotary kiln, a cooler and an airflow line system. The utility model adopts a small shaft which can directly pass through a grate plate and can support the grate plate. The front grate plate turns over and gears on the back grate plate. The balance and the operation of the grate plate can be maintained. The width of the grate plate can be decreased. The design is more suitable for the glacon chain grate machine. The secondary downdraught is added in the drying and preheating system of the chain grate machine. The hot air in the preheating section of the back part of the chain grate machine is drawn into the dry section. The hot air of the chain grate machine is utilized secondarily. The energy consumption is saved. The improved chain grate machine is applied to the pellet cooling at the back of the rotary kiln. Thus, the energy consumption is saved. The utility model can be used for producing the acid pellet used for the blast furnace ironmaking, the vanadium and titanium pellets or the magnetic material used for producing the permanent magnet.
Description
Technical field the utility model relates to a kind of pelletizing drying, preheating chain grate machine.
The dry chain grate machine of the existing pelletizing of background technology is to make several grate plates of horizontally-arranged keep balance and operation with the support roller mode, also is not used in the chain grate machine of cooling.
The summary of the invention the purpose of this utility model is at above-mentioned present situation, aims to provide a kind of non conveyor idler system secondary downdraught chain grate machine.
The implementation of the utility model purpose is that non conveyor idler system secondary downdraught chain grate machine comprises chain grate machine 1, rotary kiln 2.Chain grate machine 1 includes the upper and lower castor bed 19,21 that is driven by power transmission shaft 20, and upper and lower castor bed in top, bottom bellows 22,23, connects hot waste gas pipeline 29 respectively on the top bellows 22.Green-ball belt feeder 8 links to each other with chain grate machine 1 by circle roll screen 9, takes back rotary kiln 2 behind the chain grate machine.Little axle 25 passes and holds up upper and lower castor bed 19,21, and little axle is outer roller bearing 26, and roller bearing 26 moves on top, lower tracks 27,28.Coal gas burner 5 is arranged in rotary kiln 2.Gas generator 4 is connected by airduct and cooler 3 by 10, No. 2 air blasts 11 of 6, No. 1 air blasts of gas pipe.Cooler 3 is connected by warm-air pipe 12 and chain grate machine 1, and the chain grate machine back segment is connected by hot waste gas pipe 18 and high-temperature blower 7, and the chain grate machine leading portion is connected by hot waste gas pipe 13 and air-introduced machine 15, chimney 16.Between hot waste gas pipe 13 and the air-introduced machine 15 deduster 14 is arranged.
The utility model has following advantage:
1, adopt little axle 25 directly to pass grate plate and hold up grate plate, the front comb board upset rides on the back comb board, can keep the balance and the operation of grate plate, can reduce the grate plate width, and this design is fit to middle-size and small-size chain grate machine more.
2, in the drying of chain grate machine and pre-heating system, increased secondary downdraught,, the hot blast of chain grate machine has been carried out the secondary utilization, saved energy resource consumption the about 500 ℃ of hot blast suction dryer section of chain grate machine rear portion preheating section.
3, the chain grate machine after will improving is used for the pelletizing cooling of rotary kiln back, blast cold wind from No. 1 air blast 10 in chain grate machine 1 bottom, make cold wind pass the high temperature pelletizing, and it is combustion-supporting that the hot blast of cooler 3 anterior cooling pelletizings is sent into rotary kiln 2, improved rotary kiln sintered temperature, No. 2 air blasts 11 blast cold wind about 300 ℃ hot blast after cooler 3 rear portion pelletizings heating and send into chain grate machine 1 rear portion dryer section and utilize, and have saved energy resource consumption.
The utility model can be used for producing acid pellet, the vanadium titanium globe that uses for blast furnace ironmaking, perhaps produces for producing the magnetic material that permanent magnet is used

Specific embodiment the utility model comprises green-ball belt feeder 8, circle roll screen 9, chain grate machine 1, rotary kiln 2, cooler 3 and air flow duct system.
During the utility model work, the spontaneous ball belt feeder 8 of material is brought into, after 9 screenings of circle roll screen, enters castor bed 19, and material after super-dry, preheating, enters rotary kiln 2 sintering at last castor bed, behind the sintering, enters cooler 3 and cools off, and promptly becomes finished product.
The utility model air-flow fortune is to being: preheated air bloats cold wind by No. 1 air blast 10, and through the hot-bulb on the cooler 3, being heated to thermal current about 900 ℃, to enter rotary kiln 2 combustion-supporting.Coal gas by gas generator 4 produces enters the burner 5 that is arranged in rotary kiln 2 through gas piping 6, and burning is chewed 5 and lighted the back at rotary kiln 2 internal combustion supply heat.The thermal current that produces in the rotary kiln 2 enters chain grate machine 1 preheating section, pass grate plate 19 and material rear portion, draw and blast the last grate plate 19 of chain grate machine 1 and the dryer section of material front portion by high-temperature blower 7, simultaneously, No. 2 air blast 11 blasts cold wind, through cooler 3 rear portions, makes air-flow along rising to 300 ℃, hot-air enters chain grate machine 1 dryer section through hot-air duct 12, uses for dry materials.The waste gas of chain grate machine dryer section through hot waste gas pipeline 13, effluxes after deduster 14 and air-introduced machine 15 enter chimney 16.
