[0001] This utility model belongs to the field of battery additive production technology, specifically relating to a combined drying device for lead-acid battery additives. Background Technology

[0002] Lead-acid batteries are rechargeable batteries whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. In the discharged state, the positive electrode is mainly composed of lead dioxide, and the negative electrode is mainly composed of lead; in the charged state, both the positive and negative electrodes are mainly composed of lead sulfate.

[0003] The production of lead-acid batteries requires the use of various additives, one of which is barium sulfate. Before using barium sulfate as an additive in lead-acid batteries, it needs to be purified. Currently, most drying devices achieve purification by heating and evaporating the water in the barium sulfate solution, causing the barium sulfate to precipitate crystals. However, the crystals obtained by this method still contain some liquid, making the resulting barium sulfate crystals unusable directly. Therefore, this application proposes a combined drying device for lead-acid battery additives. Utility Model Content

[0004] The purpose of this invention is to provide a combined drying device for lead-acid battery additives, in order to solve the problem that existing drying devices in the background art achieve purification by heating and evaporating water in a barium sulfate solution to allow barium sulfate to precipitate and crystallize. However, the crystals obtained by the above method still contain some liquid, and the resulting barium sulfate crystals cannot be used directly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined drying device for lead-acid battery additives, comprising a drying barrel, wherein the drying barrel is provided with an outer separation cylinder, an inner heating cylinder inserted into the inner side of the outer separation cylinder, and a heating unit disposed in the outer separation cylinder for heating the additive solution in the inner heating cylinder; The outer separation cylinder includes a detachably connected cylinder body and a bottom plate; The inner heating cylinder is provided with a feeding channel and a sealing unit for controlling the opening or closing of the feeding channel. The bottom of the outer separation cylinder is provided with several separation holes.

A drain outlet is provided at the drying barrel.

[0006] Preferably, the top of the drying barrel is provided with a barrel lid with an opening and closing function, and the barrel lid is provided with a steam exhaust hole.

[0007] Preferably, a heat insulation frame is provided between the outer separation cylinder and the heating unit. The heat insulation frame is sleeved on the outside of the inner heating cylinder, and the heat insulation frame and the inner heating cylinder surround a sealed heating cavity, with the heating unit located inside the heating cavity.

[0008] Preferably, the sealing unit includes a sealing plate rotatably installed inside the inner heating cylinder and a power motor for driving the sealing plate to rotate, the power motor being installed on the outer wall of the inner heating cylinder.

[0009] Preferably, the outer separating cylinder is provided with a partition, and the inner heating cylinder is inserted into the partition.

[0010] Preferably, the drying drum is equipped with a sealing unit installed at the drive shaft.

[0011] Preferably, the drive mechanism includes a first pulley mounted on a drive shaft, a belt wound around the first pulley, a second pulley connected to the belt, and a drive motor drivenly connected to the second pulley.

[0012] Preferably, the drying drum has an outer shell on its outer wall, and the drive motor is mounted on the outer shell.

[0013] Preferably, a support plate is provided inside the drying barrel.

[0014] Preferably, the drive shaft is inserted into the support plate.

[0015] Beneficial effects: This utility model provides a combined drying device for lead-acid battery additives. When the heating unit is activated, it heats the barium sulfate solution stored in the inner heating cylinder, causing the water in the barium sulfate solution to evaporate and the barium sulfate to precipitate and form crystals. The sealing plate is connected to the output shaft of the power motor. When the power motor is turned on, it can drive the sealing plate to rotate inside the inner heating cylinder. When the sealing plate is distributed horizontally, it can block the feeding channel in the inner heating cylinder. At this time, the inner heating cylinder and the outer separation cylinder are isolated from each other. When the sealing plate is distributed vertically, the feeding channel is opened, and the barium sulfate crystals precipitated in the inner heating cylinder due to heating enter the interior of the outer separation cylinder through the feeding channel. The drive mechanism is started, which drives the inner and outer separation cylinders and the inner heating cylinder to rotate. The remaining liquid on the barium sulfate crystals is thrown out through the separation hole by centrifugal force, resulting in dried barium sulfate crystals. The bottom plate is removed through the detachable cylinder body and bottom plate in the outer separation cylinder, and the barium sulfate crystals on the bottom plate are taken out. This completes the production of barium sulfate crystals. The degree of dryness of the generated barium sulfate crystals is sufficient for the production of lead-acid batteries.

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] like Figures 1-4 As shown in the figure, the present invention provides a combined drying device for lead-acid battery additives, including a drying barrel 1, a barrel lid 2 with an opening and closing function on the top of the drying barrel 1, and a steam exhaust port 18 on the barrel lid 2. During the production of lead-acid battery additives, a drying process is required. During drying, the additive in solution form is heated to evaporate the water inside, and the evaporated water vapor is discharged through the steam exhaust port 18.

[0020] There are various additives for lead-acid batteries, one of which is barium sulfate. Before using barium sulfate as an additive in lead-acid battery manufacturing, it needs to be purified. This facilitates subsequent control of the dosage, reduces impurities in the lead-acid battery, and improves battery performance. During the purification process, the barium sulfate solution needs to be dried to separate the liquid from the solution and obtain barium sulfate crystals.

[0021] To dry barium sulfate, an outer separation cylinder 3, an inner heating cylinder 4 inserted into the inner side of the outer separation cylinder 3, and a heating unit 5 located inside the outer separation cylinder 3 for heating the additive solution (barium sulfate solution) in the inner heating cylinder 4 are provided inside the drying drum 1.

[0022] When the heating unit 5 is activated, it heats the barium sulfate solution stored in the inner heating cylinder 4, causing the water in the barium sulfate solution to evaporate and the barium sulfate to precipitate and form crystals.

The bottom of the outer separation cylinder 3 is provided with several separation holes 9.

[0025] The sealing plate is connected to the output shaft of the power motor. When the power motor is turned on, it can drive the sealing plate to rotate inside the inner heating cylinder 4. When the sealing plate is distributed horizontally, it can block the feeding channel 8 in the inner heating cylinder 4. At this time, the inner heating cylinder 4 and the outer separation cylinder 3 are isolated from each other. When the sealing plate is distributed vertically, the feeding channel 8 is opened, and the barium sulfate crystals precipitated in the inner heating cylinder 4 due to heating enter the interior of the outer separation cylinder 3 through the feeding channel 8. At this time, the drive mechanism drives the inner and outer separation cylinders 3 and the inner heating cylinder 4 to rotate. The remaining liquid on the barium sulfate crystals is thrown out from the separation hole 9 by centrifugal force, and the dried barium sulfate crystals are obtained. The bottom plate is removed through the detachable cylinder body and bottom plate in the outer separation cylinder 3, and the barium sulfate crystals on the bottom plate are taken out.

[0029] In summary, this utility model embodiment provides a combined drying device for lead-acid battery additives. When the heating unit 5 is activated, it can heat the barium sulfate solution stored in the inner heating cylinder 4, causing the water in the barium sulfate solution to evaporate, and causing the barium sulfate inside to precipitate and form crystals.

[0030] The sealing plate is connected to the output shaft of the power motor. When the power motor is turned on, it can drive the sealing plate to rotate inside the inner heating cylinder 4. When the sealing plate is distributed horizontally, it can block the feeding channel 8 in the inner heating cylinder 4. At this time, the inner heating cylinder 4 and the outer separation cylinder 3 are isolated from each other. When the sealing plate is distributed vertically, the feeding channel 8 is opened, and the barium sulfate crystals precipitated in the inner heating cylinder 4 due to heating enter the interior of the outer separation cylinder 3 through the feeding channel 8. At this time, the drive mechanism drives the inner and outer separation cylinders 3 and the inner heating cylinder 4 to rotate. The remaining liquid on the barium sulfate crystals is thrown out from the separation hole 9 by centrifugal force, and the dried barium sulfate crystals are obtained.
