[0026] As described in the background, in the aluminum electrolysis industry, on the one hand, the particles of the discharged materials are uneven during the feeding process. Directly adding them into the electrolytic cell without classification will affect the quality of electrolysis and increase the impurities at the bottom of the electrolytic cell. On the second hand, in the common pipeline feeding system, because the feeding materials are all in granular form, there is a problem of pipeline blockage during the transmission process, and material nodules appear at the blocked position. The particle size cannot meet the feeding requirements and must be cleaned out separately and ground into the target particle size before feeding. These two problems in the prior art seriously affect the electrolysis efficiency and electrolyte amount of electrolytic aluminum. Therefore, the utility model provides a feeding purification device and an electrolysis system in an electrolytic aluminum system. The utility model is described in detail below.
[0027] In the first aspect, the utility model provides a feeding purification device in an electrolytic aluminum system, comprising: a feed pipe 1, a first air chamber 2, a second air chamber 3, a first discharge port 4 and a second discharge port 5, wherein the first air chamber 2 and the second air chamber 3 are connected through a bend pipe, the first discharge port 4 is arranged at the bottom of the first air chamber 2, and the second discharge port 5 is arranged at the bottom of the second air chamber 3. Among them, the first air chamber 2 comprises a cylindrical section 21 and a conical section 22, the first discharge port 4 is connected to the conical section 22, and the feed pipe 1 is connected to the cylindrical section 21; the second air chamber 3 comprises a feed plate 31 and a filter element 32, the feed plate 31 is obliquely arranged at the bottom of the filter element 32, the second discharge port 5 is connected to one end of the feed plate 31, a fan 6 is arranged outside the air outlet of the second air chamber 3, and the fan 6 sucks the material from the feed pipe 1 into the first air chamber 2, the first discharge port 4 and the second discharge port 5 are respectively used to output materials of different specifications, and the filter element 32 is used to purify the material entering the second air chamber 3.
[0028] As described above, the feeding and purification device in the electrolytic aluminum system provided in the utility model includes a feeding pipe 1, a first air chamber 2, a second air chamber 3, a first discharge port 4 and a second discharge port 5. The first air chamber 2 and the second air chamber 3 are connected through a bend pipe. The first discharge port 4 is arranged at the bottom of the first air chamber 2, and the second discharge port 5 is arranged at the bottom of the second air chamber 3. When the inhaled material passes through the first air chamber 2, the larger particles fall on the bottom of the first air chamber 2 and are discharged from the first discharge port 4, and the smaller particles are inhaled into the second air chamber 3. The second air chamber 3 includes a feeding plate 31 and a filter element 32. After being filtered and purified by the filter element 32, this part of the material falls on the feeding plate 31 at the bottom of the second air chamber 3, and the material is sent to the second discharge port 5 through the inclined feeding plate 31 and discharged. The utility model realizes the classification and purification of materials and can be used as a feeding device in an electrolytic aluminum system. The materials discharged from the first discharge port 4 and the second discharge port 5 are respectively added to the electrolytic cell 7 to participate in electrolysis or serve as a covering layer material of the electrolytic cell 7. The technical problems raised in the background are solved, the feeding device in the existing electrolytic aluminum system is optimized, and the quality of electrolytic aluminum is improved.
[0029] Among them, Figure 1 and Figure 2 As shown, the first air chamber 2 includes a cylindrical section 21 and a conical section 22, the first discharge port 4 is connected to the conical section 22, and the feed pipe 1 is connected to the cylindrical section 21. After the material sucked into the cylindrical section 21 by the fan 6, it swirls in the area, so that the larger particles in the material have time and space to fall, so that the smaller particles in the material have time and space to separate from the large particles, and are further sucked into the second air chamber 3. After passing through the cylindrical section 21, the larger particles fall directly into the conical section 22, and the conical section 22 gathers and collects this part of the material and then passes it into the first discharge port 4. In this embodiment, the length and volume of the cylindrical section 21 and the conical section 22 in the first air chamber 2 are not specifically limited, and need to be adaptively designed according to the actual material and the parameters of the fan 6.
[0030] The second air chamber 3 includes a feed plate 31 and a filter element 32. The feed plate 31 is tilted at the bottom of the filter element 32. The second discharge port 5 is connected to one end of the feed plate 31. The fan 6 is arranged outside the air outlet of the second air chamber 3. The fan 6 sucks the material from the feed pipe 1 into the first air chamber 2. The first discharge port 4 and the second discharge port 5 are respectively used to output materials of different specifications, and the filter element 32 is used to purify the material entering the second air chamber 3.
[0031] like Figure 3 and Figure 4 As shown, the filter element 32 also includes a first cloth belt 321 arranged transversely and a second cloth belt 322 arranged longitudinally, and the surface of the second cloth belt 322 is perpendicular to the feeding direction of the second air chamber 3. Figure 3 and Figure 4 The black arrows in the figure indicate the direction in which the material enters and exits the second air chamber 3.
[0032] In this embodiment, the filter element 32 uses a cloth belt to filter the material, wherein the filtering cloth belt is arranged in layers in order to increase the filtering and purification effect, wherein the second cloth belt 322 in the feed inlet area is arranged perpendicular to the feed direction, so that the material is directly in contact with the multi-layer cloth belt after being sucked in. In addition, when the material filtered by the second cloth belt 322 falls onto the first cloth belt 321, the material is filtered and purified by the double-layer cloth belt again.
[0033] It should be noted that a material or structure for purifying materials can be provided on the first cloth tape 321 to increase the purification effect; or, the pass rates of the second cloth tape 322 and the first cloth tape 321 can be set to be different, such as the pass rate of the second cloth tape 322 is greater than the pass rate of the first cloth tape 321, so that the material is quickly filtered by the second cloth tape 322 and then enters the first cloth tape 321 for detailed filtration and purification.
[0034] Of course, in some embodiments, multiple layers of the second cloth tape 322 and the first cloth tape 321 may be provided to further enhance the filtering and purification effect of the material.
[0035] In some embodiments, the filter element 32 may further include a steel frame and a turntable, wherein the steel frame is engaged with a plurality of first cloth belts 321 and a plurality of second cloth belts 322 to fix the positions of the first cloth belts 321 and the second cloth belts 322. The turntable is arranged in one-to-one correspondence with the steel frame, and the driving device drives the turntable to rotate or vibrate.
[0036] In this embodiment, a steel frame is provided to fix the posture of the cloth belt. In addition, a turntable is provided to be connected to one end of the steel frame. When it is necessary to clean the material deposited on the first cloth belt 321 or the second cloth belt 322, the driving device controls the turntable to rotate or shake, so that the deposited material is quickly separated from the cloth belt under the action of centrifugal force. This can also be used as a design for purifying the cloth belt. Compared with the existing method of quickly opening and closing a pulse valve to release compressed air, forming a pulse airflow that enters the cloth belt in the opposite direction to deform the cloth belt, and the deformation and vibration of the cloth belt shakes off the dust on the cloth belt, the cloth belt can be prevented from being expanded and deformed multiple times in this embodiment, so that the pore size of the cloth belt changes. At the same time, the cloth belt can be protected from damage, thereby increasing the service life of the cloth belt.
[0037] In some embodiments, two adjacent second cloth belts 322 are staggered in the vertical direction. By staggering, the pores between the adjacent second cloth belts 322 can be staggered, which can further improve the filtration or purification of materials.
[0038] In other embodiments, the cross section of the steel frame for fixing the first cloth belt 321 and the second cloth belt 322 is a regular polygon. The regular polygon steel frame is easy to install, can also reduce the gap between adjacent cloth belts, and can also improve the compatibility of cloth belt installation.
[0039] like Figure 4 As shown, the second air chamber 3 includes a first air cavity and a second air cavity, and the filter element 32 is arranged between the first air cavity and the second air cavity. The first cavity is arranged on the upper layer of the second air chamber 3, the filter element 32 is arranged in the middle, and the second cavity is arranged on the bottom layer. The first cavity can make the inhaled material have space to be evenly distributed above the filter element 32, and the second cavity can not only temporarily store a part of the filtered and purified material, but also increase the fluidity of the airflow in the entire second air chamber 3.
[0040] Second, as Figure 5 As shown, the utility model provides an electrolysis system, which includes the charging and purification device in any of the aforementioned aluminum electrolysis systems, and also includes an electrolytic cell 7, and the electrolytic cell feed port 71 is used to connect with the second discharge port 5 to add the purified material into the electrolytic cell 7 for reaction.
[0041] The electrolytic cell 7 further comprises a heat preservation covering material feed port 72, the first discharge port 4 is connected to the heat preservation covering material feed port 72, and the second discharge port 5 is connected to the electrolytic cell feed port 71; the first discharge port 4 and the second discharge port 5 both comprise control valves.
[0042] In the electrolytic aluminum system, the electrolytic cell 7 is layered, and the surface layer of the electrolytic cell 7 serves as a heat-insulating covering layer, that is, it plays the role of heat-insulating the electrolytic cell 7 and isolating the external air. This part of the electrolyte does not need to participate in the electrolysis process. The real electrolytic layer is located below the heat-insulating covering layer, and the added alumina powder is also directly introduced into this layer for electrolysis. The particle size of the alumina powder required for this part is relatively small, and the particle size of the alumina powder required for the heat-insulating covering layer does not need to be too small. Therefore, the larger particles of material separated by the first discharge port 4 can be introduced into the heat-insulating covering layer of the electrolytic cell 7 through the heat-insulating covering material feed port 72, and the filtered and purified material can be introduced into the electrolytic layer of the electrolytic cell 7 through the electrolytic cell feed port 71 for electrolytic reaction. This feeding device of the utility model effectively improves the quality of the electrolytic aluminum material, realizes automatic feeding, and optimizes the structure of the existing electrolytic system.
[0043] In actual system design, the discharge speed of the first discharge port 4 and the second discharge port 5 can be controlled by setting a control valve, or the feed speed of the insulation covering material feed port 72 and the electrolytic cell feed port 71 can be controlled. The specific valve type is not specifically limited in this embodiment.
[0044] In other embodiments, the electrolysis system may further include a grinder, which is connected to the first discharge port 4 and then to the electrolytic cell feed port 71. The grinder grinds the larger particles of alumina powder discharged from the first discharge port 4 to meet the particle size requirements for electrolysis, and then the ground material is directly introduced into the electrolytic cell feed port 71 to participate in the electrolysis process, thereby improving the feeding rate and the use value of the material.
[0045] Finally, the utility model provides a feeding purification device and an electrolysis system in an electrolytic aluminum system, the feeding purification device comprises a feeding pipe 1, a first air chamber 2, a second air chamber 3, a first discharge port 4 and a second discharge port 5, the first air chamber 2 and the second air chamber 3 are connected through a bend pipe, the first discharge port 4 is arranged at the bottom of the first air chamber 2, and the second discharge port 5 is arranged at the bottom of the second air chamber 3. Among them, the first air chamber 2 comprises a cylindrical section 21 and a conical section 22, the first discharge port 4 is connected to the conical section 22, and the feeding pipe 1 is connected to the cylindrical section 21; the second air chamber 3 comprises a feeding plate 31 and a filter element 32 for purifying the material entering the second air chamber 3, the feeding plate 31 is obliquely arranged at the bottom of the filter element 32, the second discharge port 5 is connected to one end of the feeding plate 31, a fan 6 is arranged outside the air outlet of the second air chamber 3, and the first discharge port 4 and the second discharge port 5 are respectively used to output materials of different specifications. The utility model realizes the classification and purification of materials, optimizes the feeding device in the existing electrolytic aluminum system, and improves the quality of electrolytic aluminum.
