Description

Technical Field

[0001] The utility model relates to the technical field of sensible heat recovery equipment, in particular to a silo with a material guide cone component and a vertical cooling kiln. Background Art

[0002] A vertical cooling kiln is a device that recovers the sensible heat carried by high-temperature ore. It consists of a kiln body and ancillary components. High-temperature sintered ore is lifted and fed to the top of the kiln body by a chain rail conveyor. The sintered ore is then distributed throughout the kiln body via a distributor located above the kiln body. Finally, it falls through a distribution hopper and trough onto a chain plate conveyor below the kiln body. During this process, the sintered ore slides downward, while cold air exchanges heat with the sintered ore from below. After dust removal, the sintered ore enters the waste heat recovery network. As the sintered ore slides downward within the kiln body, due to the varying shapes and weights of the ore, larger ore rolls to the sides while smaller ore moves toward the center. This causes material distribution segregation at the bottom of the kiln body, affecting material flow and rate.

[0003] Therefore, how to overcome the above-mentioned technical problems and defects becomes a key issue that needs to be solved. Summary of the Invention

[0004] The purpose of the present utility model is to provide a silo and a vertical cooling kiln with a material guide cone assembly to solve the problems raised in the above background technology.

[0006] Furthermore, a plurality of straight lining plates are fixedly connected to the inner wall of the warehouse body, and avoidance grooves adapted to the supporting beams are provided on the straight lining plates. One end of the supporting beam falls into the avoidance groove and is welded and fixed to the straight lining plates.

[0007] Furthermore, the upper surfaces of the material tray and the supporting beam are both provided with collecting troughs, and protective linings are provided on both sides of the supporting beam.

[0008] Furthermore, an annular assembly plate is welded and fixed to the outer side of the upper portion of the intermediate column, a connecting plate is welded and fixed to the end of the supporting crossbeam, and the connecting plate and the annular assembly plate are fixedly connected by bolts.

[0009] Furthermore, a plurality of annular protective plates are welded and fixed at equal intervals on the outer side of the middle column.

[0010] The vertical cooling kiln comprises a kiln body, wherein one or more silos with the above-mentioned material guide cone components are arranged at the lower part of the kiln body.

[0011] Furthermore, the kiln body is cylindrical, there is one silo, the upper end of the silo is circular, and the lower part of the silo is hole-shaped.

[0012] Furthermore, the kiln body is cylindrical, and there are multiple silos. The upper end of the silo is fan-shaped, and the lower part of the silo is hole-shaped. The upper ends of the multiple silos form a cylindrical shape that matches the inner wall of the kiln body.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model discloses a silo with a material guide cone assembly, wherein a material guide cone assembly is added to the silo body, and a material guide cone with pointed ends and a large middle portion is located above the material port of the silo. When the ore passes through the material guide cone, the ore located on the central axis of the silo body is mixed with the ore on the outside in a radial direction under the dual coordination of the shape of the silo body and the shape of the pouring cone, thereby ensuring that the ore in the silo body forms a mass flow flow, which not only improves the segregation of the ore, but also improves the material flow rate.

[0015] The utility model relies on the existing kiln structure and makes technical improvements to the local part of the bin body, thereby improving the situation of material distribution segregation without investing in the high cost of purchasing a new vertical cooling kiln.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 5 The present invention provides a vertical cooling kiln comprising a kiln body 10, with a plurality of silos 20 having material guide cone assemblies disposed below the kiln body 10. The kiln body 10 in this embodiment is cylindrical, and there are six silos 20. The upper ends of the silos 20 are fan-shaped, and the lower portions of the silos 20 are hole-shaped. The upper ends of the plurality of silos 20 form a cylindrical shape that fits within the inner wall of the kiln body 10.

[0025] The silo 20 includes a silo body 21 and a material guide cone assembly 30 arranged in the silo body 21. The material guide cone assembly 30 includes a material tray 31, a supporting beam 32, an intermediate column 33 and a material guide cone 34. The material tray 31 and the material guide cone 34 are respectively fixedly connected to the upper and lower ends of the intermediate column 33. One end of the supporting beam 32 is fixedly connected to the upper part of the intermediate column 33, and the other end is fixedly connected to the silo body 21. There are three supporting beams 32 evenly distributed on the intermediate column 33 in the circumferential direction. The material guide cone 34 is located above the material port of the silo body 21. The material guide cone 34 is a structure with pointed ends and a large middle.

[0026] Multiple straight liner panels 22 are fixedly attached to the inner wall of the silo 21. These panels are provided with relief slots 23 that mate with the support beams 32. The outer ends of the support beams 32 fall into the relief slots 23 and are then welded to the straight liner panels 22. Both the hopper 31 and the support beams 32 have material collection chutes 35 on their upper surfaces. Protective liner panels 35 are welded to both sides of the support beams 32. These protective liner panels 35 are welded and wear-resistant, preventing direct impact of falling material on the support beams 32.

During factory fabrication, the guide cone assembly is constructed with the support beams 32 and intermediate columns 33 as separate components, while the material tray 31, guide cone 34, and intermediate columns 33 are integrated. After the three support beams 32 and intermediate columns 33 are installed within the silo 21, they are bolted together, requiring the use of a hand chain hoist. The guide cone assembly occupies approximately 0.38 cubic meters and has a total mass of approximately 1.3 tons. Finally, the silo 20 is installed beneath the kiln body 10. The ore then slides down the slide 40 onto the chain track 50 for transport to the next workstation.
