Description

Technical Field

[0001] The utility model relates to the technical field of crude lead refining equipment, in particular to a crude lead continuous refining furnace. Background Art

[0002] Lead smelting At present, most of the crude lead produced in the world adopts the process of preliminary fire refining + electrolytic refining. Almost all the crude lead produced in my country adopts this process for refining. The lead grade of crude lead produced by smelting is generally 90% to 98%, containing precious metals such as Ag and Au and impurity elements such as Cu, As, Sb, Sn, Bi, S, etc., including Cu0.1% to 5%. Due to the high impurity content, it cannot be directly electrolytically refined. Electrolytic refining requires that the lead anode plate contains Pb ≥ 98.5% (except lead-antimony alloy), Cu ≤ 0.06%, As ≤ 0.4%, and Sb is controlled at 0.4% to 0.8%. The purpose of fire refining is to remove some impurities in the smelted crude lead so that it can meet the quality requirements of lead anode plates for electrolytic refining.

[0003] After searching, as disclosed in the publication number CN213273724U, by rotating the baffle 15, the horizontal height of the baffle 15 can be adjusted, so as to control whether the flow port is opened or closed, thereby conveniently achieving the effect of controlling whether the heating pool 20 and the high-temperature pool 30 are connected. When the baffle 15 is extended to close the flow port, the crude lead liquid is introduced into the heating pool 20 through the liquid inlet 16 provided on the side of the furnace body 10, and the heating pool 20 is preliminarily heated by the first burner 13 to maintain the temperature in the heating pool 20 at 340°C. Sulfur is added to the heating pool 20 through the dosing port, so that the crude lead liquid can partially precipitate impurities. Then, the baffle 15 is contracted to open the flow port, and the filter layer 53 in the heating pool 20 preliminarily separates impurities in the crude lead liquid. After filtration and separation, the crude lead that has been initially refined enters the high-temperature pool 30, and the high-temperature pool 30 is heated by the second burner 14 to a temperature of 450°C. The oxidant is added to the high-temperature pool 30 through the dosing port to precipitate the impurities in the crude lead liquid again. Then, the crude lead liquid is pumped into the cooling pipe 41 in the reflux pool 40 through the lead pump 60, and a low-temperature medium is introduced into the cooling pipe 41 to absorb the heat in the crude lead liquid, so that the temperature of the lead liquid is gradually reduced. By utilizing the characteristics of low melting point and high density of metallic lead and the decrease in solubility of impurities in the crude lead liquid as the temperature decreases, when the temperature decreases, the impurities are precipitated, and the precipitated impurities are filtered and separated by the filter layer 53 in the reflux pool 40. Finally, the refined lead liquid is discharged from the liquid outlet 17.

[0004] In the above-mentioned technical solution, filtering is performed through a filter element, but the filter element cannot be disassembled and cleaned quickly and stably. Long-term cleaning may easily lead to clogging of the filter element, thereby reducing the overall filtering effect. For this reason, we propose a crude lead continuous refining furnace.

[0033] Embodiment 1

[0034] See also Figures 1 to 4The utility model provides a technical solution: a crude lead continuous refining furnace, comprising a furnace body 1 and two filter components symmetrically arranged on the furnace body 1. Each filter component comprises a driving component, a filter component, and an auxiliary support component. The furnace body 1 is used for crude lead refining.

[0035] The filter assembly includes a filter plate 9, which penetrates through a side wall of the furnace body 1 and is slidably connected to a side wall of the furnace body 1. The filter plates 9 in the two filter assemblies form a filter layer inside the furnace body 1.

[0036] The filter assembly is used to filter the crude lead refining raw material. The filter plate 9 is made of high temperature resistant metal or high temperature resistant synthetic metal. There is a filter plate 9 in each of the two filter components, and the two filter plates 9 form a relatively large filter plate inside the furnace body 1, that is, a filter layer.

[0037] The driving assembly includes two electric cylinders 5, which are fixedly mounted on the two side walls of the furnace body 1, and the output shaft ends of the two electric cylinders 5 are transmission-connected to the filter assembly, and the output shaft ends of the two electric cylinders 5 are detachably connected to the filter assembly.

[0038] The driving assembly is used to drive the filter assembly so that the filter assembly can be pulled out of the inner cavity of the furnace body 1; at the same time, the driving assembly is directly detachably connected to the filter assembly, that is, after the filter assembly is driven out of the furnace body 1, it can be removed under the operation of an external device. After the two electric cylinders 5 are started at the same time, the output shafts of the two electric cylinders 5 push the filter plate 9 to move to the side away from the inner cavity of the furnace body 1, so that the filter plate 9 is separated from the furnace body 1.

[0039] The auxiliary support assembly is arranged on a side wall of the furnace body 1 close to the filter plate 9, and the output shaft of the electric cylinder 5 is drivingly connected to the auxiliary support assembly.

[0040] The auxiliary support assembly is used to support the filter plate 9 to prevent the filter plate 9 from tilting when it is separated from the furnace body 1. At the same time, the electric cylinder 5 is also a driving source of the auxiliary support assembly. Under the drive of the electric cylinder 5, the auxiliary support assembly is unfolded or folded.

[0041] Specifically, a feed port 3 is provided on one side wall of the upper portion of the furnace body 1 , a discharge port 4 is provided on the other side wall of the lower portion of the furnace body 1 , and a plurality of support legs 2 are fixedly connected to the lower portion of the furnace body 1 .

[0042] The feed port 3 on the furnace body 1 is used to add crude lead raw materials. The discharge port 4 is used to discharge the refined lead liquid in the furnace body 1. Each support leg 2 is used to support the furnace body 1.

[0043] More specifically, the filter assembly further includes a sealing plate 7 and a handle 8 . The sealing plate 7 is fixedly disposed on an edge of one side of the filter plate 9 , and the handle 8 is fixedly mounted on the sealing plate 7 .

[0044] The sealing plate 7 is used to seal the joint between the filter plate 9 and the furnace body 1 to prevent the raw materials inside the furnace body 1 from flowing out. The handle 8 is used to facilitate workers or external equipment to take the filter assembly.

[0045] More specifically, the output shaft ends of the two electric cylinders 5 in the driving assembly are fixedly mounted with clamping plates 6, and the lower parts of both ends of the sealing plate 7 are provided with card slots 10, and the clamping plates 6 are detachably connected to the sealing plate 7 through the card slots 10. Two baffles 11 are fixedly connected to the outer wall of the furnace body 1. The baffles 11 are used to limit the clamping plates 6.

[0046] The output shaft of the electric cylinder 5 pushes the clamping plate 6 to move to the side away from the furnace body 1, and the clamping plate 6 drives the sealing plate 7 to move. The baffle 11 no longer limits the sealing plate 7 on the clamping plate 6. The baffle 11 is used to prevent the sealing plate 7 from being separated from the clamping plate 6 during sealing. The sealing plate 7 drives the entire filter assembly to move to the side away from the furnace body 1. The output shafts of the two electric cylinders 5 extend and push the filter assembly to move to the side away from the furnace body 1. After the filter assembly moves to the maximum amount, the staff or external equipment removes the sealing plate 7 from the clamping plate 6.

[0047] More specifically, the auxiliary support assembly includes two groups of telescopic parts, each group of telescopic parts is composed of a fixed block 12, a sleeve 13 and a sliding rod 14. The fixed block 12 is fixedly installed on an outer wall of the furnace body 1 and close to the filter plate 9. One end of the sleeve 13 is rotatably connected to the fixed block 12, one end of the sliding rod 14 is inserted into the other end of the sleeve 13, and the sliding rod 14 is slidably connected to the sleeve 13, and the other end of the sliding rod 14 is rotatably connected to the clamping plate 6.

[0048] Among them, the output shaft of the electric cylinder 5 pushes the clamping plate 6 to move to the side away from the furnace body 1, the clamping plate 6 drives the sealing plate 7 to move, and the sealing plate 7 drives the entire filter assembly to move to the side away from the furnace body 1; at the same time, during the movement, the clamping plate 6 pushes the sliding rod 14 to move to the side away from the furnace body 1, and the sliding rod 14 slides and extends from the sleeve 13. At the same time, the sleeve 13 and the sliding rod 14 rotate a certain angle with the central axis of the fixed block 12. After the sleeve 13 and the sliding rod 14 are rotated and extended to a certain angle, they are located below the filter plate 9. The sleeve 13 and the sliding rod 14 support the filter plate 9 to prevent the filter plate 9 from tilting.

[0049] During use, when it is necessary to clean the filter plate 9 in the furnace body 1, the electric cylinder 5 is started, and the telescopic shaft of the electric cylinder 5 will push the clamp 6 to move toward the end away from the furnace body 1. The clamp 6 will drive the sealing plate 7 to move, and the sealing plate 7 will drive the filter plate 9 to slide out of the furnace body 1. In the process of the filter plate 9 sliding out, the clamp 6 will also drive the sliding rod 14 at the bottom to move, so that the sliding rod 14 slides out of the sleeve 13 and extends, and drives the sleeve 13 to rotate around the hinge with the fixed block 12. When the clamp 6 brings the sealing plate 7 to make the filter plate 9 completely slide out of the furnace body 1, the sleeve 13 also rotates a certain angle, and the bottom end of the sliding part of the filter plate 9 is held up by the sleeve 13. At this time, the top of the clamp 6 is no longer blocked by the baffle 11, so that the two ends of the sealing plate 7 are no longer restricted, and the handle 8 can be pulled to take out the sealing plate 7 and the filter plate 9. Then the filter plate 9 can be cleaned, and after cleaning, the filter plate 9 is placed on the sleeve 13, and the slot 10 is aligned with the clamping plate 6 to clamp it, and then the electric cylinder 5 is contracted to reinsert the filter plate 9 into the furnace body 1, thereby facilitating disassembly and installation.

[0052] The auxiliary support assembly includes two groups of support members, each group of support members is composed of a fixed block 12 and a rotating rod 18. The fixed block 12 is fixedly installed on an outer wall of the furnace body 1 and close to the filter plate 9. One end of the rotating rod 18 is rotatably connected to the fixed block 12, and a slide groove 19 is provided on the rotating rod 18. One end of the sliding shaft 17 is adapted to the slide groove 19, and the vertical rod 16 is slidably connected to the rotating rod 18 through the sliding shaft 17.

[0054] During the movement, the filter plate 9 in the filter assembly is pulled out of the inner cavity of the furnace body 1. At the same time, the sliding shaft 17 moves horizontally, and the sliding shaft 17 drives the rotating rod 18 to rotate a certain angle. The rotating rod 18 rotates 90 degrees with the fixed block 12 as the central axis. After the rotation, the rotating rod 18 is in a horizontal direction, and the rotating rod 18 supports the filter plate 9 to prevent the filter plate 9 from tilting.
