Problems solved by technology

The defects of method 1 and method 2 are very obvious. In method 1, the new receiving chute has a large volume and a weight of about 20 tons. The moving distance from the receiving chute to the corresponding position is relatively long, which is difficult, labor-intensive, and dangerous during the construction process; in the second method, the maintenance of the receiving chute requires a long downtime, and the welding workload Large, it is difficult to overhaul in high temperature environment

Embodiment 1

[0048] Such as Figure 1-5 As shown, the material receiving chute is under the floor 2, the floor 2 plays the role of fixing the hopper 6 and the dust removal pipe 7, and the material receiving chute is located between the upper smoke hood 5 and the dust removal hood 3, so when the dust removal hood 3 is lifted out and the cutting After the old material receiving chute 4, the old material receiving chute 4 needs to be transported out through the reverse rotation of the annular cooler, and then the new material receiving chute 8 is transported into the annular cooler through the forward rotation of the annular cooler , so as to avoid the collision between the material receiving chute and the upper smoke hood 5 when transporting the material receiving chute, the specific steps are as follows,

[0049] When replacing the material receiving chute, fix the position of the hopper 6, cut the connection between the old material receiving chute 4 and the hopper 6, place the old materia...

Embodiment 2

[0051] As another embodiment of the invention, such as Figure 8 As shown, the material receiving chute is under the floor 2, and the floor 2 plays the role of fixing the hopper 6 and the dust removal pipe 7, and there is only the dust removal cover 3 on one side of the material receiving chute. To rotate and transport the old material receiving chute 4 and the new material receiving chute 8 simultaneously, the specific steps are as follows,

[0052] When replacing the material receiving chute, fix the position of the hopper 6, cut the connection between the old material receiving chute 4 and the hopper 6, place the old material receiving chute 4 in the trolley 1 of the annular cooler directly below, and at the same time place the new material receiving chute 8 Placed in the external annular cooler trolley 1, start the annular cooler to rotate in reverse, the annular cooler trolley 1 transports the old material receiving chute 4 out of the outside, while the new material recei...

Abstract

The invention relates to a method for replacing a receiving chute of an annular cooler. The method comprises the following steps that a new receiving chute is manufactured; a sintering machine system is shut down, and materials between a sintering machine and the annular cooler are emptied; a dust removal cover is Lifted out; the position of a hopper is fixed, the connection between an old receiving chute and the hopper is cut, the old receiving chute is placed in an annular cooler trolley right below the old receiving chute, the annular cooler is started to rotate, the old receiving chute is conveyed to the outside by the annular cooler trolley, the new receiving chute is placed in the annular cooler trolley, the annular cooler is started to rotate, and the cooler trolley conveys the new receiving chute to the position below the hopper; the new receiving chute is in butt joint with the hopper, and the new receiving chute is connected with the hopper in a welded mode; and the dust removal cover is reassembled. According to the method, the frequency of cutting the receiving chute is reduced, the receiving chute only needs to be integrally cut at one time, the process of replacing the receiving chute is effectively simplified, the downtime of the sintering machine and the annular cooler is shortened, the maintenance labor intensity is reduced, and the safety risk is reduced.

Description

technical field [0001] The invention relates to the technical field of annular coolers, in particular to a method for replacing a receiving chute of an annular cooler. Background technique [0002] Annular cooler, referred to as annular cooler, is a large-scale equipment for metal smelting enterprises. It is composed of bellows, trolley, receiving chute and other parts. It is usually used in sintering production and pellet production. Its function is to cool the high-temperature sinter Or pellet cooling, the volume and weight of the equipment are very large, which is the key equipment for sintering production or pellet production. The material receiving chute of the ring cooler is a device for loading materials into the ring cooler. The material receiving chute needs to transfer a large amount of material, but because the material receiving chute has been in contact with the high-temperature sintering hot ore for a long time, the material receiving chute that has been used f...
