Description

Technical Field

[0001] This utility model relates to the technical field of battery recycling equipment, specifically to a battery waste acid recycling device. Background Technology

[0002] The production process of lead-acid batteries generates a large amount of waste sulfuric acid (referred to as waste acid), mainly from the waste acid produced during the coating process and the waste acid generated during battery charging. The concentration of waste sulfuric acid generated during coating is approximately 10%, while the concentration of waste acid generated during battery charging is approximately 35%. Waste acid mainly contains impurities such as lead powder and has a high acid content. Direct neutralization followed by discharge would not only pollute the environment but also waste a large amount of acid and alkali, resulting in high treatment costs and making it difficult to meet the energy conservation and emission reduction requirements of enterprises.

[0003] Currently, most companies that generate waste acid from batteries lack complete self-treatment facilities, and the recycling of waste acid is mainly carried out by sulfuric acid manufacturers. However, the treatment of lead-containing waste acid mostly adopts complex and bulky waste acid purification equipment, which has problems such as high power consumption, high collection and purification costs, and poor purification effect. This often leads to the discharge of wastewater containing acid and lead exceeding the standards, seriously threatening the environment and human health.

[0004] Existing patent CN202585683U discloses a battery waste acid recycling device. This device achieves low-cost, low-energy recycling of battery waste acid through sedimentation and triple filtration purification. Its filtration process relies on the weight of the filtrate and the liquid's properties, requiring no additional energy, and the purification cost is only 2% of traditional purification costs. However, this device still has some limitations in practical applications: its filtration efficiency is relatively low, and the fixed filter bucket is prone to clogging of the filter holes, affecting the filtration speed and recycling efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a battery waste acid recovery device, which solves the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a battery waste acid recovery device, comprising a sedimentation tank, a collection tank, multiple filter tanks, multiple first filter buckets, and a driving component. Each filter tank is longitudinally fixedly installed from top to bottom, and a perforation is provided on the top wall of each filter tank, allowing adjacent filter tanks to communicate through the perforation. The first filter buckets are rotatably installed inside the filter tanks. The sedimentation tank is fixedly installed above the uppermost filter tank and is connected to it. The collection tank is fixedly installed below the lowermost filter tank and is connected to it. The driving component includes a rotating shaft that passes through the bottom wall of the collection tank, the bottom wall of each first filter bucket, and the perforation on each filter tank. The rotating shaft is rotatably connected to the bottom wall of the collection tank, and its outer side is fixedly connected to the bottom wall of the first filter bucket.

[0009] Optionally, the drive component further includes a motor, which is fixedly installed below the collection box, and the output shaft of the motor is fixedly installed at the lower end of the rotating shaft.

[0010] Optionally, a connecting pipe is fixedly installed on the side wall of the sedimentation tank and the two are connected. The end of the connecting pipe away from the sedimentation tank is fixedly installed on the top wall of the uppermost filter box, and the connecting pipe is connected to the interior of the uppermost filter box.

[0011] Optionally, a drain pipe is fixedly installed on the bottom wall of the collection box and the two are connected.

[0012] Optionally, an installation rod is fixedly installed inside the uppermost filter box, and a rotating roller is fitted onto the outer wall of the installation rod and the two are rotatably connected. Numerous bristles are fixedly connected to the outer wall of the rotating roller.

[0013] (III) Beneficial Effects

[0014] This utility model provides a battery waste acid recovery device, which has the following beneficial effects:

[0015] This battery waste acid recovery device, through the coordinated arrangement of a sedimentation tank, a collection tank, multiple filter tanks, multiple first filter buckets, and a drive unit, achieves highly efficient filtration of waste acid. The waste acid is filtered in multiple stages through the various first filter buckets. During this multi-stage filtration process, the rotating shaft in the drive unit drives the rotation of each first filter bucket. The rotation of the first filter bucket generates centrifugal force, which forces the waste acid within it through the filter holes in the first filter bucket, thus achieving highly efficient filtration. Compared to existing technologies, using a drive unit to rotate each first filter bucket effectively improves the filtration efficiency of waste acid under the action of centrifugal force. The rotating and paused first filter buckets reduce or prevent clogging of the filter holes, greatly increasing the filtration speed and improving the waste acid recovery efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0024] Example 1, please refer to Figures 1 to 2 The present invention provides a technical solution: a battery waste acid recovery device includes a sedimentation tank 2, a collection tank 11, multiple filter boxes 1, multiple first filter buckets 8 and a driving component. Each filter box 1 is longitudinally fixedly installed from top to bottom. A leakage hole 5 is provided on the top wall of the filter box 1, and two adjacent filter boxes 1 are connected through the leakage hole 5.

[0025] The two adjacent filter boxes 1 can be threaded together for easy opening (opening the filter box 1 facilitates cleaning of particles inside the first filter hopper 8). The inner wall of the filter box 1 is inclined. The first filter hopper 8 is used to filter waste acid, and it has numerous filter holes. The waste acid flows through the perforations 5 within each filter box 1.

[0026] The first filter hopper 8 is rotatably installed inside the filter box 1. The sedimentation box 2 is fixedly installed above the uppermost filter box 1, and the sedimentation box 2 is connected to the uppermost filter box 1. The collection box 11 is fixedly installed below the lowermost filter box 1, and the collection box 11 is connected to the lowermost filter box 1.

[0027] The drive component includes a rotating shaft 6, which passes through the bottom wall of the collection box 11, the bottom wall of each first filter hopper 8, and the leakage hole 5 on each filter box 1. The rotating shaft 6 is rotatably connected to the bottom wall of the collection box 11, and the rotatable connection is sealed to prevent waste acid leakage. The outer wall of the rotating shaft 6 is fixedly connected to the bottom wall of the first filter hopper 8. The drive component also includes a motor 7, which is fixedly installed below the collection box 11, and the output shaft of the motor 7 is fixedly installed to the lower end of the rotating shaft 6.

[0028] The first filter buckets 8 are arranged longitudinally, and the waste acid flows through each first filter bucket 8 sequentially, ensuring thorough filtration. A sedimentation tank 2 holds the waste acid liquid, and the waste acid in the sedimentation tank 2 flows into the filter box 1. A motor 7 drives a rotating shaft 6 to rotate, which in turn rotates each first filter bucket 8. While filtering the waste acid, the high-speed rotation of each first filter bucket 8 generates centrifugal force, increasing the filtration speed and enhancing filtration efficiency. A collection box 11 collects the filtered waste acid liquid.

[0029] Specifically, a connecting pipe 3 is fixedly installed on the side wall of the sedimentation tank 2 and the two are connected. The end of the connecting pipe 3 away from the sedimentation tank 2 is fixedly installed on the top wall of the uppermost filter box 1, and the connecting pipe 3 is connected to the interior of the uppermost filter box 1.

[0030] The waste acid in the sedimentation tank 2 flows into the topmost filter box 1 through the connecting pipe 3, and the waste acid flows through each filter box 1 in sequence.

[0031] Specifically, a drain pipe 12 is fixedly installed on the bottom wall of the collection box 11 and the two are connected.

[0032] The drain pipe 12 is used to discharge the filtered waste acid from the collection box 11.

[0033] When in use, the waste acid liquid containing waste materials from the storage battery is placed into the sedimentation tank 2 for sedimentation. After the waste materials settle, the waste liquid overflows into the lower filter tank 1 through the connecting pipe 3. The waste acid liquid flows through each of the first filter buckets 8 in sequence, and finally flows into the collection tank 11. The waste acid liquid is finally discharged through the drain pipe 12.

[0034] In the above process, motor 7 drives shaft 6 to rotate, and motor 7 drives each first filter hopper 8 to rotate through shaft 6, so that the waste acid liquid is thrown out by centrifugal force when passing through each first filter hopper 8. This helps to improve the filtration speed and the recovery efficiency of waste acid liquid.

[0035] Example 2, please refer to Figures 3 to 4The main difference between this embodiment and Embodiment 1 is that: an installation rod 13 is fixedly installed inside the filter box 1 located at the top layer, and a rotating roller 14 is fitted on the outer wall of the installation rod 13 and the two are rotatably connected. Numerous bristles 15 are fixedly connected to the outer wall of the rotating roller 14. The outer wall of the rotating roller 14 abuts against the outer wall of the first filter hopper 8 located at the top layer.

[0036] The mounting rod 13 is used to support the rotating roller 14. When the rotating shaft 6 rotates, it drives the first filter bucket 8 located at the top layer to rotate. When the first filter bucket 8 rotates, it drives the rotating roller 14 to rotate. When the rotating roller 14 rotates, each bristle 15 will be inserted into the filter hole of the first filter bucket 8. The bristles 15 brush and press the filter hole, causing the particles in the filter hole to fall off and preventing the particles from clogging the filter hole.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
