[0034] Combination Figure 1-Figure 6 As shown, a cooling device for a rotary assembly of a blast furnace mud gun machine includes a mounting frame 10, a water pipe 20, a first nozzle 30, and a tee pipe 21. The mounting frame 10 is vertically fixed on the table top of the turntable 1, the working end of the mounting frame 10 is spaced apart from the table top of the turntable 1, and the setting path of the mounting frame 10 is consistent with the horizontal cross-sectional profile of the turntable 1. A plurality of water pipes 20 are vertically arranged and fixedly arranged on the mounting frame 10, and a water outlet is provided on the inner side surface of each water pipe 20. A plurality of first nozzles 30 are fixedly arranged on the water pipe 20 and connected to the water pipe 20, and the output ends of the first nozzles 30 are fan-shaped arranged from top to bottom under the plumb projection. The input end of the tee pipe 21 is arranged between adjacent first nozzles 30 and connected to the water pipe 20, and the output end of the tee pipe 21 faces one side of the first nozzle 30.

[0035] It should be noted that during the operation of the blast furnace mud gun machine, high-temperature slag or waste materials usually splash and contaminate the surface of the blast furnace mud gun machine rotary assembly, and the cooling device of the blast furnace mud gun machine rotary assembly in the present application is mainly used in the cleaning and cooling operation scene of the surface of the blast furnace mud gun machine rotary assembly. The cooling device of the blast furnace mud gun machine rotary assembly in the present application is composed of a mounting frame 10, a water pipe 20, a first nozzle 30, and a three-way pipe 21.

[0036] The mounting frame 10 is vertically fixed on the table of the turntable 1. The setting path of the mounting frame 10 is consistent with the contour of the table of the mounting table, so that the first nozzle 30 set on the inner side of the water pipe 20 can spray the entire table of the turntable 1, sweeping the slag and fly ash on the table of the turntable 1 while cooling the turntable 1. The output end of the first nozzle 30 is arranged in a fan shape in the vertical plane, so that the first nozzle 30 can spray different positions and angles of the turntable 1, and the spray coverage of the first nozzle 30 is wider. A plurality of first nozzles 30 are set on the water pipe 20 to improve the cleaning effect and cooling efficiency of the first nozzle 30 on the turntable 1. The input end of the tee pipe 21 is arranged between adjacent first nozzles 30 at intervals, and its output end faces the first nozzle 30. The tee pipe 21 sprays the water pipe 20 and the mounting frame 10 in the opposite direction to realize the self-cleaning function of the cooling device.

[0037] The tee pipe 21 includes a belly pipe 211 and a shoulder pipe 212; the belly pipe 211 is vertically arranged on one side of the water pipe 20 close to the first nozzle 30, the input end of the belly pipe 211 is connected to the water pipe 20, and it is arranged between adjacent first nozzles 30, and the output end of the belly pipe 211 extends to the inside of the water pipe 20. The shoulder pipe 212 is fixedly arranged on the top of the belly pipe 211, and the length of the shoulder pipe 212 is greater than the spacing distance between adjacent first nozzles 30. The input end of the shoulder pipe 212 is rotatably connected to the output end of the belly pipe 211, and the second nozzles 40 are fixedly arranged at both ends of the axial length of the shoulder pipe 212, the second nozzle 40 is connected to the shoulder pipe 212, and the output direction of the second nozzle 40 is toward one side of the first nozzle 30.

[0038] The three-way pipe 21 in the present application is in a "T"-shaped structure as a whole, and is composed of a belly pipe 211 and a shoulder pipe 212. The belly pipe 211 is connected to the middle part of the shoulder pipe 212, and the belly pipe 211 is connected to the water pipe 20, so that the external cooling water source can be passed into the water pipe 20. The two ends of the shoulder pipe 212 are respectively connected to the second nozzle 40 with the output direction facing the first nozzle 30, so that when water flows in the shoulder pipe 212, the cooling water is sprayed in the opposite direction to the water pipe 20, the first nozzle 30 and the mounting bracket through the second nozzle 40, so as to avoid the slag and ash from being contaminated by the water pipe 20, the first nozzle 30 and the mounting bracket 10 for the second time when the first nozzle 30 sprays, so as to achieve the self-cleaning function.

[0039] A bearing 22 is fixedly provided at the connection point between the belly tube 211 and the shoulder tube 212 . The outer side surface of the bearing 22 is fixedly connected to the inner side surface of the belly tube 211 , and the inner side surface of the bearing 22 is sleeved to the outer side surface of the shoulder tube 212 .

[0040] In the above scheme, the arrangement of the bearing 22 can realize the relative rotation between the shoulder tube 212 and the belly tube 211. The bearing 22 is arranged on the inner side of the belly tube 211, and the shoulder tube 212 is sleeved on the inner side of the bearing 22, so that the shoulder tube 212 and the belly tube 211 can rotate. The two second nozzles 40 are connected at both ends of the axial length direction of the shoulder tube 212, and the output end of the second nozzle 40 faces one side of the first nozzle 30. When the external cooling water source is introduced into the shoulder tube 212, the spraying direction of the second nozzle 40 is opposite to the spraying direction of the first nozzle 30. Since the length of the shoulder tube 212 is greater than the spacing distance between adjacent first nozzles 30, the spraying path of the second nozzle 40 is always located beside the first nozzle 30, so that the second nozzle 40 can effectively clean the surface of the water pipe 20 beside the first nozzle 30, so as to avoid the slag, waste and ash from contaminating the water pipe 20 again, and at the same time increase the cooling area of ​​the blast furnace rotary assembly by the cooling device in the present application, and improve the cooling effect of the cooling device.

[0041] The upper side surface of the upper part of the shoulder tube 212 is an arc surface from outside to inside and from top to bottom, and the lower side surface of the lower part of the shoulder tube 212 is an arc surface from inside to outside and from bottom to top.

[0042] The purpose of such arrangement is that, since the shoulder pipe 212 and the belly pipe 211 are rotatably connected via the bearing 22, when the spraying surface of the first nozzle 30 intersects with the upper side of the shoulder pipe 212, the cooling water will form an upward impact on the upper side of the shoulder pipe 212, so that the shoulder pipe 212 can rotate upward (clockwise) around the bearing 22, and when the spraying surface of the first nozzle 30 intersects with the lower side of the shoulder pipe 212, the cooling water will form a downward impact on the lower side of the shoulder pipe 212, so that the shoulder pipe 212 can rotate downward (counterclockwise) around the bearing 22. The shoulder pipe 212 and the belly pipe 211 rotate, which not only increases the spraying angle of the second nozzle 40 on part of the surface of the water pipe 20, the table of the turntable 1, and part of the surface of the mounting frame 10, but also avoids manual secondary cleaning of the turntable 1 and the surface of the water pipe 20, reduces the labor intensity of workers and saves water resources.

[0043] The mounting frame 10 includes a column 11 and a half joint 12; one end of the plurality of columns 11 is fixedly arranged on the table surface of the turntable 1, and the arrangement path of the columns 11 is consistent with the contour of the edge of the turntable 1, and the other end of the column 11 is threadedly connected to the bottom of the half joint 12. The half joint 12 is clamped on the outside of the water pipe 20, and can constrain the relative position of the water pipe 20 and the turntable 1.

[0044] The mounting frame 10 in the present application is composed of a plurality of columns 11 and half joints 12. The setting path of the columns 11 is consistent with the edge profile of the turntable 1, ensuring that the spraying area of ​​the first nozzle 30 can cover the surface area of ​​the turntable 1, so as to ensure effective spraying and cooling of the first nozzle 30. The columns 11 are screwed with the half joints 12 to facilitate the installation and disassembly of the mounting frame 10. The purpose of using the half joints 12 to constrain the water pipes 20 is to facilitate the installation of the water pipes 20. The staff only needs to use threaded connection to constrain the water pipes 20 in the annular channel formed by the half joints 12.

[0045] The cooling device in the present application also includes an external water circuit 50, the output end of the external water circuit 50 is screwed to the outside of the water pipe 20 and communicated with the water pipe 20, a valve 51 is arranged between the output end of the external water circuit 50 and the input end of the water pipe 20, the input end of the valve 51 is communicated with the output end of the external water circuit 50, and the output end of the valve 51 is communicated with the input end of the water pipe 20.

[0046] In the above scheme, the external water circuit 50 is connected to the water pipe 20 in a threaded connection form, so that the staff can set the cooling device in this application according to different construction environments. A valve 51 is set between the external water circuit 50 and the water pipe 20, so that the staff can control the start and stop of the spraying operation of the first nozzle 30 and the second nozzle 40 while avoiding the waste of cooling water.

[0047] A heat shield 60 is fixedly provided on the circumference of the turntable 1, the inner side of the heat shield 60 is in contact with the side of the turntable 1, and the cross-sectional profile of the heat shield 60 in horizontal projection is consistent with the cross-sectional profile of the turntable 1. The heat shield 60 is provided to prevent the components inside the turntable assembly from being damaged due to the splashing of slag and the strong heat radiation environment during the operation of the turntable assembly, thereby increasing the service life of the turntable assembly.
