Description

Technical Field

[0001] This utility model belongs to the field of storage battery production technology, and in particular relates to a lead powder screening mechanism for storage battery production. Background Technology

[0002] The active materials of the positive and negative plates of a storage battery are made by mixing lead powder with sulfuric acid, water, etc. to form lead paste, which is then coated and formed. The quality of the lead powder (such as oxidation degree, apparent density, and acid absorption rate) directly determines the physicochemical properties of the lead paste, which in turn affects the porosity, conductivity, and utilization rate of the active materials of the plates.

[0003] In the battery production process, screening lead powder is a key step to ensure stable battery performance, improve production efficiency, and reduce defect rates. Large lead powder particles can lead to excessively high plate porosity, longer sulfuric acid diffusion paths, and insufficient reaction of active materials during charging and discharging, thus reducing battery capacity and cycle life. However, in the current battery production process, lead powder is not screened during transportation. Large-diameter lead powder is mixed with qualified lead powder and then directly applied to the negative plate, resulting in frequent equipment jams and a high scrap rate. Utility Model Content

[0022] Please see Figure 1-5 As shown, this utility model is a lead powder screening mechanism for battery production, including a fixed frame 1, a screening cylinder 2 slidably sleeved inside the fixed frame 1, a vibration motor 13 fixedly connected inside the fixed frame 1, the end of the vibration motor 13 fixedly connected to the screening cylinder 2, a discharge pipe 3 fixedly connected to the bottom end of the screening cylinder 2, a support ring 4 fixedly connected to the inner wall of the screening cylinder 2, lead powder enters the screening cylinder 2 and is discharged from the discharge pipe 3, the support ring 4 is welded to the lower part of the screening cylinder 2, leaving a large space above the screening cylinder 2, so that a large amount of lead powder can be retained when screening lead powder, the discharge pipe 3 is connected to the conveyor belt by a fixed hoop, the vibration motor 13 is fixedly connected to the outside, and one end of it is connected to the fixed frame 1, the vibration of the vibration motor 13 drives the fixed frame 1 and the screening cylinder 2 to vibrate together, so as to realize the vibration screening of lead powder inside the screening cylinder 2; The top cover 5 is threaded to the top of the screening cylinder 2. The top of the top cover 5 is fixedly connected to the feed pipe 6. The top of the outer surface of the screening cylinder 2 is provided with a threaded groove. The top cover 5 is threaded together with the screening cylinder 2. When the staff regularly inspects the conveyor belt, the top cover 5 can be opened to inspect the inside of the screening cylinder 2. The feed pipe 6 is connected to the conveyor belt by a fixing hoop and is connected to the conveyor cylinder. The lead powder is transported into the screening cylinder 2 through the feed pipe 6. When the screening cylinder 2 is vibrating and screening, since the conveyor belt is soft, it will not affect other devices.

The lead powder with a larger particle size will be continuously pushed by the rectangular cover 73. After the drive motor 71 rotates in reverse, the lead powder with an unsuitable particle size can move to the bottom of the rectangular cover 73 and be sucked into the interior of the rotating shaft 72 through the holes at the bottom of the rectangular cover 73. One side of the scraper 75 can contact the inner wall of the screening cylinder 2 to scrape off the lead powder adhering to the inner wall of the screening cylinder 2, avoiding the lead powder from remaining inside the screening device and causing waste of lead powder.

A support rod 102 is fixedly connected to the outer surface of the threaded sleeve 101, and a scraper 103 is fixedly connected to the end of the support rod 102. The scraping assembly 10 can scrape the lead powder on the inner wall of the screening cylinder 2 and the inner wall of the discharge pipe 3 below the screen plate 9, while the scraper 103 scrapes the lead powder on the inner wall of the screening cylinder 2 above the screen plate 9. A threaded groove is opened at the bottom end of the rotating shaft 72, and the threaded sleeve 101 is threadedly connected to the bottom end of the rotating shaft 72. When replacing the screen plate 9, the scraping assembly 10 can be removed to easily remove and replace the screen plate 9.

[0024] Please see Figure 1 , 6As shown in Figure 7, a specific application of this embodiment is as follows: Slots 11 are provided on both sides of the inner wall of the feed pipe 6. An iron removal assembly 12 is installed inside the feed pipe 6. The iron removal assembly 12 can magnetically attract the iron powder passing through the lead powder. Since iron particles are highly conductive, if they deposit on the surface of the battery plates, they may form micro-short circuits, reducing battery capacity and cycle life. Furthermore, iron impurities can catalyze the oxidation of lead powder, accelerating battery self-discharge and affecting storage performance. Therefore, iron removal of the lead powder is essential. The iron removal assembly 12 includes a magnetic ring 121. Both sides of the outer surface of the magnetic ring 121 are fixedly connected with clamping rods 122. The iron removal component 12 is clamped to the feed pipe 6 by the clamping rods 122, which restricts the iron removal component 12 inside the clamping groove 11. It is also very convenient to pick up and put away the iron removal component 12. The bottom of the outer surface of the magnetic ring 121 is fixedly connected with a connecting rod 123. The top of the magnetic ring 121 is adapted to the inner diameter of the feed pipe 6, and the bottom is smaller. The lead powder slides down along the inclined interior of the magnetic ring 121. In this process, the iron impurities mixed in the lead powder can be retained. Several connecting rods 123 are fixedly connected to the magnetic ring 121. A collection box 124 is fixedly connected to the bottom of rod 123. A collar 125 is fixedly connected to the bottom of the inner surface of the collection box 124. A second drive motor 126 is fixedly installed on the bottom of the inner wall of the collection box 124. One end of the output shaft of the second drive motor 126 is fixedly connected to a second rotating shaft 127 via a coupling. The top end of the second rotating shaft 127 extends into the interior of the magnetic ring 121. A scraper 128 is fixedly connected to the end of the second rotating shaft 127. An electric telescopic rod 129 is fixedly connected inside the collection box 124. The top end of the electric telescopic rod 129 is fixedly installed with... There is a receiving plate 1210, which is sleeved with the rotating shaft 127. After the lead powder enters the screening cylinder 2, the drive motor 126 starts and drives the scraper 128 to scrape the iron impurities on the inner wall of the magnetic ring 121. At the same time, the electric telescopic rod 129 retracts and the receiving plate 1210 retracts downward. The scraped iron impurities can fall along the receiving plate 1210 into the collection box 124. When normal lead powder enters the screening cylinder 2, the lead powder slides directly down along the receiving plate 1210 and along the upper surface of the collection box 124.
