The present embodiment provides a sintering distribution apparatus that can be used for distribution on a sintering pallet. Specifically, as shown in fig. 1, the sintering distribution device comprises a distribution mechanism 1, a mixing mechanism 2, a leveling mechanism 3 and an ignition furnace 4.

Wherein the distributing mechanism 1 comprises a first bin 11 and a second bin 12. The first bin 11 is used for containing the sintering mixture 200, the second bin 12 is used for containing the fuel 300, and the materials can be simultaneously distributed through the first bin 11 and the second bin 12 in the process of distributing the materials. The discharge hole of the first bin 11 is opposite to the trolley bottom plate 101, and the sintering mixture 200 directly falls on the trolley bottom plate 101 from the discharge hole of the first bin 11 to form a first mixture layer 201. That is, the sinter mix 200 is directly spread on the pallet base plate 101 by the method of pulling the pallet, without providing a distributing roller, a multi-roller distributor, etc. to assist in distributing, and the structure is simple, and the failure is not easy to occur. The second bin 12 is arranged downstream of the first bin 11 along the running direction of the trolley, and the direction indicated by an arrow in the figure is the moving direction of the trolley. The fuel 300 is discharged from the discharge port of the second bin 12, falls onto the first mixed material layer 201, and continues to move along with the trolley.

The distributing mechanism 1, the mixing mechanism 2, the leveling mechanism 3 and the ignition furnace 4 are arranged in sequence along the running direction of the trolley (the direction indicated by the arrow in fig. 1). The fuel 300 is mixed with the sintering mixture 200 at the upper part of the first mixed material layer 201 through the mixing mechanism 2 to form a second mixed material layer 401, so that the distribution of the solid fuel 300 in the material layer on the trolley bottom plate 101 is changed, namely, the fuel 300 in the second mixed material layer 401 is redundant to the fuel 300 in the first mixed material layer 201. The leveling mechanism 3 is used for leveling the upper surface of the second mixed material layer 401, the ignition furnace 4 ignites the second mixed material layer 401, and the sintering process is performed from top to bottom. The fuel 300 in the second mixed material layer 401 is high in content and high in combustion temperature in the initial combustion stage, so that the strength of the upper-layer sinter is improved, meanwhile, the temperature of the first mixed material layer 201 is improved by hot gas which burns downwards, the condensation of water vapor is reduced, the air permeability of the sintering process is improved, the yield is improved, and the overall fuel consumption is reduced.

With continued reference to fig. 1, the dispensing mechanism 1 further includes a material loosening assembly 13. The loosening assembly 13 is connected to the first bin 11 and located between the discharge port of the first bin 11 and the trolley bottom plate 101, and the loosening assembly 13 is used for scattering the sintering mixture 200 discharged from the first bin 11, so as to facilitate sufficient combustion of the sintering mixture 200.

Specifically, the first bin 11 includes a first hopper 111, a first side wall 112, and a second side wall 113. The first hopper 111 is internally provided with the sintering mixture 200, the outlet of the first hopper 111 is a discharge outlet, the first side wall 112 and the second side wall 113 are respectively connected below the first hopper 111, and the first side wall 112 is positioned at the upstream of the second side wall 113 along the running direction of the trolley. The cross-sectional dimension of the first hopper 111 is gradually reduced from top to bottom so that the sinter mix 200 flows downward, and the first and second sidewalls 112 and 113 are capable of guiding the sinter mix 200.

Still more specifically, the distance from the bottom of the first side wall 112 to the trolley floor 101 is less than the distance from the bottom of the second side wall 113 to the trolley floor 101 and the height of the trolley fence 102. That is, the first side wall 112 extends below the pallet rail to facilitate better spreading of the sinter mix 200 within the first hopper 111 over the pallet floor 101. Preferably, the bottom of the first side wall 112 is spaced from the trolley floor 101 to prevent it from obstructing movement of the trolley. The loose assembly 13 comprises a plurality of loose material sheets 131, the loose material sheets 131 are arranged on the first side wall 112 at intervals, and the extending direction of the loose material sheets 131 is parallel to the running direction of the trolley. The plurality of loose material pieces 131 are used for scattering the sintering mixture 200 falling from the discharge port and then spreading the scattered material on the trolley bottom plate 101 so as to increase the air permeability of the sintering mixture 200, enable the sintering mixture to be fully combusted and improve the combustion efficiency.

More specifically, the loose material sheets 131 are provided in a plurality of rows, the plurality of rows of loose material sheets 131 being arranged at intervals in the height direction of the first side wall 112, and the plurality of loose material sheets 131 in each row being arranged at intervals in the width direction of the first side wall 112. The above arrangement of the loose material pieces 131 can make the particles of the sinter mix 200 falling from the first hopper 111 more uniform and finer. Preferably, the plurality of loose material sheets 131 in each row are arranged offset from the plurality of loose material sheets 131 in its adjacent row. It will be appreciated that the number and arrangement of the loose material sheets 131 may be adjusted according to the field requirements, and the present embodiment is not limited herein.

Preferably, as shown in fig. 3, the width of the top of the loose material sheet 131 is smaller than the width of the bottom thereof. In the present embodiment, the longitudinal section of the loose material sheet 131 has a shape of an upper triangle and a lower rectangle. The triangular tip is more advantageous for cutting apart the particles of the sinter mix 200. Of course, in other embodiments, the longitudinal cross-sectional shape of the loose material sheets 131 may be a semi-circle on the upper side and a rectangle on the lower side, and the large particles of the sinter mix 200 may be separated.

More specifically, to make the structure of the loose material sheets 131 more stable, the loose material assembly 13 further includes a bracket 132. The brackets 132 are disposed parallel to and spaced apart from the first side wall 112 and upstream of the first side wall 112.

That is, the inner wall of the supporting hole may provide a fulcrum for the loose material sheet 131, and the larger the distance between the first sidewall 112 and the bracket 132, the better the stability of the loose material sheet 131 when the sinter mixture 200 falls down, the less the shaking.

As shown in fig. 1 and 2, the first silo 11 also includes a shutter 14. The shutter 14 is abutted against the second side wall 113 and is capable of sliding in the height direction of the second side wall 113 to adjust the thickness of the first mixed material layer 201.

Specifically, the first silo 11 also includes an adjustment assembly 15. The adjustment assembly 15 includes a rack 151 and a gear 152 in meshed engagement. The rack 151 is fixedly connected to a side of the shutter 14 facing away from the second sidewall 113, and extends in the height direction of the second sidewall 113. The gear 152 is rotatably connected to the first bin 11, and the gear 152 rotates to drive the shutter 14 to move up and down along the height direction of the second sidewall 113. When the shutter 14 moves downward, the thickness of the first mixed material layer 201 decreases; when the shutter 14 moves upward, the thickness of the first mixed material layer 201 increases.

Still more specifically, the adjustment assembly 15 further includes a drive member. The output end of the driving member is connected to the gear 152 to drive the gear 152 to rotate in either a forward or reverse direction. In this embodiment, the driving member may be selected from the prior art motors.

As shown in fig. 1, the second bin 12 includes a second hopper 121 and a dosing assembly 122. The dosing assembly 122 is disposed at an outlet of the second hopper 121 to discharge the fuel 300 in the second hopper 121 toward the trolley.
