Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation equipment for aluminum electrolysis cells, specifically to a cooling blower device for the furnace side of an aluminum electrolysis cell. Background Technology

[0002] In electrolytic production, when the temperature on the side of the electrolytic cell is lower than the primary crystallization temperature of the electrolyte, the polymer components in the electrolyte will crystallize and precipitate on the side of the electrolytic cell, forming a side crust, known as the furnace lining. The furnace lining plays a crucial role in the stability and safety of the electrolytic cell's operation and production in the aluminum electrolysis industry. During electrolytic production, the electrolyte temperature is affected by many factors and changes rapidly. If the electrolyte temperature is frequently higher than the furnace lining formation temperature, the side furnace lining gradually melts and thins, and the side carbon bricks may be oxidized and corroded. In severe cases, this can lead to electrolytic cell damage and large-scale melt leakage accidents, affecting the safety of electrolytic production. Therefore, in actual production, air cooling is often used to cool the furnace lining to ensure a stable furnace lining thickness and guarantee safe and reliable production. Because dust easily accumulates on both sides of the electrolytic cell, it can easily fall into the air supply equipment during cleaning. When dust accumulates and forms scale in the air supply equipment, it significantly reduces the airflow and may even clog the fan blades, severely affecting the normal cooling effect of the air supply equipment on the electrolytic cell and greatly reducing cooling efficiency. Utility Model Content

[0006] Furthermore, a lower dust filter is provided at the air inlet of the cooling fan and / or an upper dust filter is provided at the air outlet of the blower nozzle.

[0007] Furthermore, the blower nozzle is provided with multiple air-distributing blades.

[0008] Furthermore, the blower nozzle includes an upper flat nozzle portion and a lower cylindrical portion. The flat nozzle portion gradually widens from bottom to top and to both sides. The air distribution blades include a left blade disposed in the left region of the flat nozzle portion and a right blade disposed in the right region of the flat nozzle portion. The left blade is tilted to the left and the right blade is tilted to the right.

[0009] Furthermore, a bladeless area is provided at the lower part between the left and right regions where the air distribution blades are provided in the flat nozzle, and the bladeless area gradually narrows from the bottom of the flat nozzle upwards.

[0010] Furthermore, the top of the flat nozzle is a rectangular air outlet, and the flat nozzle is composed of inclined plates on the left and right sides and side plates on the front and rear sides. The side plates gradually bulge outward from their top edge and left and right sides to their bottom edge.

[0011] Furthermore, the discharge port includes an upper discharge port area located in the middle region of the bottom of the side plate behind the flat nozzle and a lower discharge port area located in the middle of the upper rear part of the cylindrical part.

[0012] Furthermore, the two sides of the air distribution blade are fitted to the inner walls of the front and rear side plates of the flat nozzle.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In one embodiment, a cooling blower device for the furnace side of an aluminum electrolysis cell is provided, such as... Figures 1-2 As shown, the aluminum electrolytic cell furnace side cooling blower device includes a blower 10, which is used to blow air to the side of the electrolytic cell for cooling. A cooling fan 20 is connected to the bottom of the blower 10, and air is blown into the blower 10 through the cooling fan 20. A material leakage port 11 is provided on the lower part of one side of the blower 10. When installing the aluminum electrolytic cell furnace side cooling blower device, the material leakage port 11 is located on the side facing the side of the electrolytic cell, so that dust or dirt falling from the side of the electrolytic cell can fall out of the blower 10 after entering it, avoiding accumulation in the blower 10 and the cooling fan 20. In this embodiment, the material leakage port 11 is formed by cutting open the lower part of the side of the blower 10. The cut metal plate is pried outward with a certain gap to form a downwardly inclined slide 12. The two sides and the lower edge of the slide 12 are cut from the side of the blower 10, and the upper edge of the slide 12 is still connected to the side of the blower 10. Figure 1 (Part of the material discharge port 11 is blocked by the slide plate 12). The dust that falls in can slide out through the slide plate 12, and the slide plate 12 can block the top of the outer side of the material discharge port 11, reducing or preventing the air in the blower nozzle 10 from leaking out of the material discharge port 11.

[0029] At the bottom of the blower nozzle 10, there is a flange plate 13 for connecting the cooling fan 20. The cooling fan 20 is connected to the bottom of the blower nozzle 10 through the flange plate 13. A hanger 14 is provided on one side of the flange plate 13 to hang the aluminum electrolytic cell furnace side cooling blower nozzle device on the side of the electrolytic cell.

[0030] Furthermore, in another embodiment, such as Figure 3 and Figure 4As shown, the aluminum electrolytic cell furnace cooling blower device has a lower dustproof net 30 at the air inlet at the bottom of the cooling fan 20 and an upper dustproof net 40 at the air outlet 13 at the top of the blower 10. During the operation of the cooling fan 20, air enters from the air inlet at its bottom, and some of the dust in the air is blocked by the lower dustproof net 30. The lower dustproof net 30 can be cleaned regularly. By setting the upper dustproof net 40, the amount of dust falling into the side of the electrolytic cell can be reduced. In particular, the detached dirt can be blocked by the upper dustproof net 40.

[0031] Furthermore, in another embodiment, such as Figure 1 As shown, the aluminum electrolytic cell furnace side cooling blower device has multiple air distribution blades 50 in the blower 10. The air distribution blades 50 divide the air duct inside the blower 10. The size and arrangement of the air distribution blades 50 are obtained through design verification, which can make the air blown out by the blower 10 evenly distributed to different areas on the side of the electrolytic cell, resulting in better heat dissipation.

[0032] Furthermore, in another embodiment, such as Figures 1-2 As shown, the nozzle 10 includes an upper flat nozzle portion 10-1 and a lower cylindrical portion 10-2. The air blown out by the cooling fan 20 enters the flat nozzle portion 10-1 through the air duct inside the cylindrical portion 10-2. The flat nozzle portion 10-1 gradually widens from bottom to top and to both sides to disperse the airflow laterally. Figures 5-6 As shown, the wind-distributing blade 50 includes a left blade 51 disposed in the left region of the flat nozzle 10-1 and a right blade 52 disposed in the right region of the flat nozzle 10-1. The left blade 51 is tilted to the left and the right blade 52 is tilted to the right. The left blade 51 and the right blade 52 are arranged symmetrically from left to right. The left blade 51 guides the wind to the left and the right blade 52 guides the wind to the right.

[0033] Furthermore, such as Figure 6 As shown, a bladeless area 15 is provided at the lower part between the left and right regions where the air distribution blades are provided in the flat nozzle 10-1. The bladeless area 15 gradually narrows from the bottom of the flat nozzle 10-1 upwards. By setting the bladeless area 15, the air distribution blades can be prevented from blocking the wind blown by the air duct in the cylindrical part 10-2 and reducing the wind speed.

[0034] Furthermore, in combination Figure 1 and Figure 4 As shown, the top of the flat nozzle 10-1 is a rectangular air outlet 16, which allows the blown air to be distributed horizontally. Figures 2-4As shown, the flat nozzle 10-1 is composed of inclined plates 17 on the left and right sides and side plates 18 on the front and rear sides. The side plates 18 gradually bulge outward from their top and left and right sides to their bottom edge. The shape of the side plates 18 makes the internal space of the flat nozzle 10-1 smoothly transition from a circle to a rectangle from the cylindrical part 10-2 to the air outlet at the top of the flat nozzle 10-1, which is conducive to smooth airflow. Figure 5 As shown ( Figure 5 The dotted line represents the shape of each air distribution blade within the flat nozzle 10-1. The two sides of each air distribution blade are attached to the inner walls of the front and rear side plates of the flat nozzle 10-1. For example, the side of the air distribution blade near the side gradually extends from top to bottom and attaches to the front and rear side plates 18, thereby forming multiple individual air intake channels within the flat nozzle 10-1.

[0035] Furthermore, in another embodiment, such as Figure 1 As shown, the material discharge port 11 of the aluminum electrolysis cell furnace side cooling blower device includes an upper material discharge port area 111 located in the middle area of ​​the bottom of the side plate 18 behind the flat nozzle portion 10-1 and a lower material discharge port area 112 located in the middle of the upper part of the rear side of the cylindrical portion 10-2. This shape of the material discharge port 11 facilitates the smooth discharge of dust. Figure 8 As shown, the aluminum electrolysis cell furnace side cooling blower device is installed on the outside of the cell shell 60 of the electrolysis cell in an inclined state, blowing air to cool the heat dissipation plate 61 on the outside of the cell shell 60. When cleaning, the dust and dirt falling from the cell shell 60 and the heat dissipation plate 61 will enter the top air outlet of the flat nozzle 10-1. Since the side plate 18 is convex outward from its top edge and left and right sides to its bottom edge, the dust and dirt will fall on the inside of the side plate 18 and slide down. Due to the shape of the side plate 18, the dust and dirt will gather towards the center during the sliding process and just leak out from the location of the upper material leakage area 111 and the lower material leakage area 112.

[0036] Furthermore, the rectangular air outlet at the top of the flat nozzle 10-1 of the cooling blower nozzle device for the aluminum electrolytic cell furnace side is 400mm-700mm long and 100mm-120mm wide. The specific size of the rectangular air outlet is set according to the size of the applicable electrolytic cell. The tilt angle of the air distribution blades 50 is 30°-60°, and the length is 40mm-200mm. The tilt angle of each air distribution blade can be different, and the length is set according to its position in the flat nozzle 10-1.

[0037] The usage of the aluminum electrolytic cell furnace side cooling blower device is as follows: Combined with... Figure 8As shown, multiple heat dissipation plates 61 are arranged on both sides of the cell shell 60 of the electrolytic cell. The aluminum electrolytic cell furnace side cooling blower device is installed on the side of the cell shell 60. The cooling air blown by the cooling fan 20 is blown onto the surface of each heat dissipation plate 61 through the blower 10. The flat nozzle 10-1 at the top of the blower 10 is an air delivery channel that changes from round to square. The cylindrical part 10-2 at the bottom of the blower 10 is a cylindrical part with a flange connected to the cooling fan 20. By setting multiple air distribution blades in the flat nozzle 10-1, it is beneficial to disperse the air to different heat dissipation plate 61 surfaces. To prevent solid particles from accumulating inside the blower nozzle 10 and jamming the blades of the cooling fan 20 during on-site cleaning and dust blowing, dust filters are installed at the air outlet of the blower nozzle 10 and the air inlet of the cooling fan 20, respectively. A material leakage port is opened on the side of the blower nozzle 10 so that dust particles that enter the interior can flow out through the material leakage port. Furthermore, the slide plate 12 is set to prevent air leakage caused by the cooling fan 20 during operation.

These are all common variations of the present invention and will not be described in detail here.
