Description

Technical Field

[0001] The utility model relates to the technical field of swing chute baking, in particular to a swing chute baking device. Background Art

[0002] In the steel smelting industry, the swing chute is a key device that connects the iron ditch and the molten iron tank. Its performance and life are directly related to the continuity and stability of blast furnace production. The slag molten iron flowing out of the blast furnace iron mouth is finely filtered by the slag skimmer, and the pure molten iron flows into the swing chute through the iron ditch, and then the swing mechanism accurately guides it into the molten iron tanks on the left and right sides to meet the continuous needs of blast furnace production. However, the working layer of the swing chute, as the part that directly bears the impact and erosion of high-temperature molten iron, its baking quality has a crucial impact on the overall life.

[0003] At present, the working layer of the swing chute is generally made by integral casting. Although this process can ensure the integrity and sealing of the working layer, it faces many challenges during the baking process. Traditional baking equipment often has the problem of uneven baking, especially concentrated at the spout of the swing chute. This is mainly due to the complex structure of the spout, with many corners and planes. Uneven baking not only causes internal stress in the working layer, but also easily causes defects such as cracks, which in turn affects the service life and safety of the swing chute during use.

[0004] Therefore, a swing chute baking device is needed to overcome the occurrence of the above problems. Utility Model Content

[0005] In order to solve the above problems, the embodiment of the utility model provides a swing chute baking device, which achieves the purpose of solving the problems raised in the background technology.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a swing chute baking device, comprising a burning rack for baking the swing chute, and a heat preservation cover for keeping the baking warm;

[0007] The combustion rack includes a main pipe for baking the groove and the spout of the swing chute, a branch pipe connected to the main pipe for baking the groove of the swing chute, a vertical pipe connected to the bottom of the main pipe for baking the spout of the swing chute, and a vertical pipe connected to the bottom of the vertical pipe for baking the spout end of the swing chute; the main pipe, branch pipe, vertical pipe and vertical pipe are all provided with gas nozzles facing the swing chute.

[0008] As a further improvement of the above technical solution:

[0009] The combustion rack is provided with a support frame for supporting the combustion rack inside the swing chute.

[0010] The support frame comprises a fixed rod fixedly connected to the main pipe, a movable rod sleeved inside the fixed rod, a positioning groove opened on the fixed rod, and a positioning block fixedly connected to the movable rod and used in conjunction with the positioning groove.

[0011] The heat-insulating cover comprises a cover body and a heat-insulating layer arranged inside the cover body. A notch for accommodating the main pipe is provided on the heat-insulating cover.

[0012] An air inlet is arranged at the bottom of the heat-insulating cover.

[0013] An observation window is arranged on one side of the heat-insulating cover.

[0014] The beneficial effects of the embodiments of the utility model are:

[0015] In actual use, the combustion rack is placed on the swing chute, and then gas is introduced into the inside of the main pipe to ignite the nozzle to burn and bake the swing chute; in this application, the nozzle is baked through the main pipe and the vertical pipe, and the nozzle end is baked through the vertical pipe, which ensures uniform baking of the nozzle and avoids a series of problems caused by uneven drying.

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0023] See also Figures 1 to 5 The embodiment of the utility model discloses a swing chute baking device, comprising a burning rack 1 for baking the swing chute, and a heat preservation cover 2 for keeping the baking warm;

[0024] The combustion rack 1 includes a main pipe 11 for baking the groove and the spout of the swing chute, a branch pipe 12 connected to the main pipe 11 for baking the groove of the swing chute, a vertical pipe 13 connected to the main pipe 11 below for baking the spout of the swing chute, and a vertical pipe 14 connected to the vertical pipe 13 below for baking the spout end of the swing chute; the main pipe 11, the branch pipe 12, the vertical pipe 13 and the vertical pipe 14 are all provided with a gas nozzle 15 facing the swing chute;

[0025] In actual use, the combustion rack 1 is placed on the swing chute, and then gas is introduced into the interior of the main pipe 11, and the gas nozzle 15 is ignited to burn and bake the swing chute; in this application, the main pipe 11 and the vertical pipe 13 are used to bake the chute nozzle, and the vertical pipe 14 is used to bake the end of the chute nozzle, that is, to ensure uniform baking of the chute nozzle and avoid a series of problems caused by uneven drying.

[0026] As a further illustration of this application:

[0027] The combustion rack 1 is provided with a support frame 3 for supporting the combustion rack 1 inside the swing chute. The combustion rack 1 is supported inside the swing chute by the support frame 3. At the same time, the length of the support frame 3 can be adjusted, thereby adjusting the distance between the air nozzle 15 on the combustion rack 1 and the swing chute, that is, adjusting the position between the flame and the swing chute to ensure the uniformity of baking.

[0028] As a further illustration of this application:

[0029] The support frame 3 includes a fixed rod 31 fixedly connected to the main pipe 11, a movable rod 32 sleeved inside the fixed rod 31, a positioning groove 33 provided on the fixed rod 31, and a positioning block 34 fixedly connected to the movable rod 32 and used in conjunction with the positioning groove 33; in actual use, the position of the movable rod 32 inside the fixed rod 31 is adjusted by adjusting the position of the positioning block 34 in the positioning groove 33, thereby meeting the purpose of adjusting the support height of the support frame 3;

[0030] The present application uses the cooperation of the positioning groove 33 and the positioning block 34 to adjust the position of the movable rod 32. This is because the temperature of the support frame 3 is high during combustion, and the use of thread adjustment is prone to the situation where the threads break and fail after high-temperature deformation. The positioning groove 33 and the positioning block 34 deform less at high temperatures, and their slight deformation does not affect the normal use of the positioning groove 33 and the positioning block 34.

[0031] As a further illustration of this application:

[0032] The heat preservation cover 2 includes a cover body 21 and a heat preservation layer 22 arranged inside the cover body 21. The heat preservation layer 22 can be made of aluminum silicate. A notch 25 for accommodating the main pipe 11 is opened on the heat preservation cover 2. The heat preservation cover 2 is used to keep the swing chute warm during baking, thereby improving baking efficiency.

[0033] As a further illustration of this application:

[0034] An air inlet 23 is provided at the bottom of the heat-insulating cover 2 , and oxygen is provided for combustion inside the heat-insulating cover 2 through the air inlet 23 .

[0035] As a further illustration of this application:

[0036] An observation window 24 is provided on one side of the heat-insulating cover 2 , so that the baking condition of the internal swing chute can be observed through the observation window 24 .
