[0026] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0027] The present application embodiment provides an automatic soot blowing device for an overhead crane on an aluminum electrolytic cell, Figure 1 ,include:

[0028] Blower mechanism 9, ventilation pipe 4, wherein:

[0029] The blower mechanism 9 is arranged on the overhead travelling crane beam 1;

[0030] The ventilation pipe 4 is arranged from bottom to top along the side wall of the anode lifting mechanism 2, and the side wall of the ventilation pipe 4 is connected to the side wall of the anode lifting mechanism 2. The lower end of the ventilation pipe 4 is provided with an air outlet 13, and the upper end is provided with an air inlet 14. The air inlet 14 is connected to the air outlet end of the air blowing mechanism 9.

[0031] Specifically, the anode lifting mechanism 2 is installed on the overhead crane beam 1 and is used for hanging the anode group for changing the poles of the electrolytic cell. The anode group includes an anode guide rod 6 and an anode carbon block 7. The anode lifting mechanism 2 is a technology well known to those skilled in the art and will not be described in detail here.

[0032] The ventilation pipe is a key component of the device, which is arranged from bottom to top along the side wall of the anode lifting mechanism. The lower end of the ventilation pipe is provided with an air outlet, which is used to blow the wind directly to the part that needs to be cleaned; the upper end is provided with an air inlet, which is connected to the air outlet end of the main air duct.

[0033] In some embodiments, the blowing mechanism 9 includes an air compressor 10, a control solenoid valve 11 and a main air duct 12, wherein the control solenoid valve is installed between the main air duct and the air compressor, and the air outlet end of the main air duct is connected to the air inlet of the ventilation duct.

[0034] Specifically, the air compressor serves as a wind source, providing stable and sufficient wind pressure and air volume to meet the needs of soot blowing. The control solenoid valve is installed between the main air duct and the air compressor to control the switch of the blowing mechanism and the size of the air volume, realizing automatic or manual control. The main air duct serves as a connecting pipe between the air compressor and the ventilation pipe, transmitting compressed air to the ventilation pipe. The air outlet of the main air duct is connected to the air inlet of the ventilation pipe to ensure smooth transmission of wind power.

[0035] When the air compressor 10 is started and the control solenoid valve 11 is opened, air is delivered from the main air duct 12 through the ventilation pipe 4 to the air outlet 13, thereby realizing the cleaning function of the upper part of the tank 8. The blowing working principle of the air compressor 10 and the working process of the control solenoid valve 11 are both prior arts, and the two cooperate with each other to realize the blowing operation. The specific technology is well known to those skilled in the art and will not be described in detail here.

[0036] In some embodiments, the diameter of the air outlet is smaller than the diameter of the ventilation pipe, the inlet end of the air outlet is connected to the ventilation pipe, the outlet end extends away from the anode lifting mechanism, and multiple air outlets are arranged side by side with intervals between each air outlet.

[0037] In some embodiments, at least part of the ventilation pipe is a retractable structure, and the retracting direction of the ventilation pipe is parallel to the lifting direction of the anode lifting mechanism, and the upper side wall of the ventilation pipe is connected to the overhead traveling girder. Since the ventilation pipe 4 is retractable, when the anode lifting mechanism 2 is lifted or lowered, the ventilation pipe 4 can be driven to lift up and down, thereby moving to a suitable position.

[0038] In some embodiments, the telescopic structure includes a telescopic portion of a ventilating pipe made of rubber material, or a bellows-type telescopic structure, or a telescopic joint-type telescopic structure, or a spiral-type telescopic structure, wherein:

[0039] The bellows-type telescopic structure comprises a tubular structure having continuous wave crests and wave troughs;

[0040] The telescopic structure of the telescopic section comprises a plurality of telescopic segments, wherein the segments comprise inner and outer sleeves relatively nested in the axial direction, and a stuffing box is used to seal the inner and outer sleeves;

[0041] The spiral telescopic structure comprises a spiral elastic structure arranged in the wall of the elastic ventilation pipe.

[0042] Specifically, in some embodiments, at least part of the ventilation pipe 4 is made of rubber material, which can make the ventilation pipe 4 retractable. In some embodiments, the retractable structure is a bellows-type retractable structure, and the bellows is a tubular structure with continuous crests and troughs, which has excellent retractability and bendability. The ventilation pipe is made of bellows material and can be freely retracted along the lifting direction of the anode lifting mechanism. The crest and trough design of the bellows can provide sufficient elasticity, so that the ventilation pipe is not easily deformed or damaged during the retraction process. In addition, the bellows also has excellent corrosion resistance and high temperature resistance, and is suitable for the harsh environment of aluminum electrolytic cells. In some embodiments, the retractable structure is a telescopic joint telescopic structure, and the telescopic joint telescopic structure realizes the telescopic function by arranging a plurality of retractable segments on the ventilation pipe. The segment includes an inner and outer sleeve that can make axial relative movement, and a stuffing box is used to seal the inner and outer sleeves. When in use, keep the two ends of the pipe moving on an axis. When the anode is lifted, the relative position between the segments changes, thereby realizing the retraction of the ventilation pipe. This structure can adjust the number and length of the segments as needed to adapt to different lifting strokes. In some embodiments, the retractable structure is a spiral retractable structure, which utilizes the characteristics of the spiral tube to achieve the retraction of the ventilation pipe. The ventilation pipe adopts a spiral design so that the ventilation pipe can be retracted like a spring during the anode lifting process. This structure has the advantages of being simple and compact, and can resist a certain degree of twisting and bending.

[0043] In some embodiments, it further includes: a spring member 5 , one end of which is fixedly connected to the overhead travelling crane beam 1 , and the other end of which is fixedly connected to the outer wall of the ventilation pipe 4 .

[0044] Specifically, the spring member 5 can improve the stability of the ventilation pipe 4 during the expansion and contraction process, especially when the anode lifting mechanism 2 rises, the spring member 5 can improve the restoring force of the ventilation pipe 4, so that the ventilation pipe 4 contracts in time to avoid bending of the ventilation pipe 4. At the same time, when the anode lifting mechanism 2 descends and the ventilation pipe 4 is stretched, the spring member 5 can also play a protective role to prevent the ventilation pipe 4 from being over-stretched.

[0045] In some embodiments, the spring element is sleeved on the outside of the ventilation pipe.

[0046] Specifically, this installation method of the spring component 5 can improve the restoring force of the ventilation pipe 4, so that the ventilation pipe 4 can be contracted in time to avoid bending of the ventilation pipe 4, and can also make the spring component 5 and the ventilation pipe 4 fit more closely, thereby improving the stability of the expansion and contraction process of the ventilation pipe 4.

[0047] In some embodiments, a fixing frame 3 is disposed on the outer wall of the anode lifting mechanism 2 , and the fixing frame 3 is fixedly connected to the lower end side wall of the ventilation pipe 4 .

[0048] In summary, compared with the prior art, the automatic soot blowing device for the overhead crane on the upper part of the aluminum electrolytic cell provided by the present application is provided with a ventilation pipe that can be raised and lowered along with the lifting and lowering of the anode lifting mechanism. When the air outlet of the ventilation pipe is aligned with the upper part of the aluminum electrolytic cell to be soot blown, the air blowing mechanism is turned on to blow soot on the upper part of the cell. The vertical height and horizontal position of the ventilation pipe can be controlled by the anode lifting mechanism, so that the air outlet of the ventilation pipe is close to and aligned with the upper part of the cell to be soot blown, so that soot blowing can be carried out effectively, and the safety of the soot blowing process is also ensured. Thus, the problem of the sanitation of the upper part of the cell being difficult to clean is solved.
