[0002] The PH adjusting device for sulfuric acid processing of a battery is a device capable of automatically or manually controlling and adjusting the pH value of a sulfuric acid solution, which is generally composed of a PH detector, a controller, an acid or alkali storage container, a delivery pump and an adjusting valve. The PH detector monitors the PH value of the sulfuric acid solution and feeds back the signal to the controller. The controller controls the amount of added acid or alkali according to the set value, so as to accurately adjust the PH value in the process of sulfuric acid processing of a battery, thereby meeting the requirements of the production process.

[0003] In some existing adjusting devices, stirring is needed after adding acid or alkali to accelerate the mixing efficiency. Some traditional stirring devices have a relatively complex structure and use a multi-stage transmission structure to realize the rotation of the stirring paddle in the processing tank. For example, the external power is transmitted to the stirring components in the tank through a gear set or a chain transmission. Such multi-stage transmission not only increases the manufacturing cost of the device, but also causes a large energy loss in the power transmission process and is relatively complex to operate. In addition, a large amount of acid or alkali or impurities will adhere to the inner wall of the adjusting device after use, which needs to be cleaned manually by the operator, which is relatively cumbersome.

DETAILED DESCRIPTION

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a pH adjustment device for processing sulfuric acid in storage batteries, including a processing tank 1. An alkali tank 3 and an acid tank 4 are fixedly connected to the outer wall of the top of the processing tank 1. An inlet pipe 6 is provided on the outer wall of the top of the processing tank 1, and an outlet pipe 5 is provided on the outer wall of the bottom of the processing tank 1. A drive mechanism 2 is provided on the inner wall of the processing tank 1. The drive mechanism 2 includes a motor 201, and a rotating shaft 202 is fixedly connected to the output shaft of the motor 201. The inner wall of the rotating shaft 202 is elastically connected by a connecting spring 203. There is a locking block 204, a rotating rod 205 is slidably connected to the outer wall of the rotating shaft 202, a locking groove 206 is opened on the outer wall of the rotating rod 205, an insert rod 207 is fixedly connected to the bottom outer wall of the rotating rod 205, a stirring rod 208 is rotatably connected to the top inner wall of the processing tank 1, a slot A209 is opened on the bottom outer wall of the stirring rod 208, a ring 210 is rotatably connected to the bottom inner wall of the processing tank 1, a slot B211 is opened on the outer wall of the ring 210, and a scraper 212 is fixedly connected to the outer wall of the ring 210.

[0022] The above scheme is adopted as follows: Processing tank 1 is the main container for processing sulfuric acid during the battery sulfuric acid processing process. It is made of acid-resistant alloy or other materials that can effectively resist sulfuric acid corrosion, which is existing technology well known to those skilled in the art and will not be described in detail here. Sulfuric acid can be poured into processing tank 1 through the liquid inlet pipe 6 at the top for processing. When it is necessary to adjust its pH value, acid or alkali can be added to the sulfuric acid solution through acid tank 4 or alkali tank 3 to control the pH value of the sulfuric acid solution and make it reach the optimal range required for battery production. Through the drive mechanism 2, the sulfuric acid can be stirred after the acid or alkali is added to speed up the mixing rate. When the appropriate pH value is adjusted, the liquid outlet pipe 5 at the bottom of processing tank 1 can be opened to discharge the sulfuric acid solution for the next processing step. The motor 201 serves as the power source. The output shaft is fixedly connected to the rotating shaft 202. When the motor starts, it can drive the rotating shaft 202 to rotate. Under normal conditions, the locking block 204 is held in place by the elastic force of the connecting spring 203 and a set of locking slots 206, so that the rotating shaft 202 can drive the rotating rod 205 to rotate synchronously. The rotating rod 205 can only move up and down on the outer wall of the rotating shaft 202 and cannot rotate independently. The outer wall of the rotating rod 205 does not contact the inner wall of the stirring rod 208, and there is a certain distance between them. There are multiple sets of slots A209 below the stirring rod 208. When the insertion rod 207 is engaged with one of the slots A209, the rotating rod 205 can drive the stirring rod 208 to rotate together, which can stir the sulfuric acid solution in the tank, so that the added acid or alkali solution is fully mixed with the sulfuric acid solution, thereby achieving uniform pH adjustment.

[0023] like Figures 2 to 4 As shown, the motor 201 is fixedly connected to the top outer wall of the processing tank 1, and the rotating rod 205 passes through the top outer wall of the processing tank 1; one end of the connecting spring 203 is fixedly connected to the outer wall of the locking block 204, and the other end of the connecting spring 203 is fixedly connected to the inner wall of the rotating shaft 202; the locking block 204 is slidably connected to the inner wall of the rotating shaft 202, and the locking block 204 is engaged with the locking slot 206; the insert rod 207 is engaged with the slot A209, the insert rod 207 is engaged with the slot B211, and the scraper 212 is in contact with the inner wall of the processing tank 1; the rotating rod 205 passes through the outer wall of the stirring rod 208, and the rotating rod 205 is rotatably connected to the top inner wall of the processing tank 1; two sets of locking slots 206 are provided, and both sets of locking slots 206 are opened on the outer wall of the rotating rod 205.

[0024] Using the above scheme: The slot 206 has two sets, upper and lower. When the lower set of slots 206 engages with the block 204, the rotating rod 205 is at the top and the insertion rod 207 engages with slot A209. The stirring rod 208 can be rotated via the rotating shaft 202 and the rotating rod 205. By pressing the block 204, it moves into the inner wall of the rotating shaft 202, releasing the limit of the rotating rod 205. When the rotating rod 205 is moved downwards, so that the upper set of slots 206 corresponds to the block 204, the connecting spring 203 causes the block 204 to pop out due to its own elasticity and engage with the upper slot 206. At this time, the insertion rod 207 engages with slot B211 and disengages from slot A209. In this state, when the rotating shaft 202 drives the rotating rod 205 to rotate, the rotating rod 205 will not drive the stirring rod 208 to rotate, but will drive the ring 2 10. Rotation: When the ring 210 rotates, the scraper 212 fixedly connected to its outer wall will move in a circular motion along the inner wall of the processing tank 1 along with the movement of the ring 210. The scraper 212 is in close contact with the inner wall of the processing tank 1. During the rotation, it can scrape off impurities, residual acid or alkali attached to the inner wall of the processing tank 1, preventing their accumulation from affecting the solution quality and equipment performance. It also helps to keep the inner wall of the processing tank 1 clean and reduce interference with the accuracy of subsequent pH adjustment. By adjusting the position of the rotating rod 205, the stirring rod 208 can be driven to rotate and stir when stirring is required. When cleaning the inner wall is required, it can be cleaned by the scraper 212. The stirring rod 208 and the scraper 212 can rotate independently and can be switched by convenient adjustment. The structure is simple and does not require the operator to manually clean the inner wall, making it more convenient to use.

[0025] Working principle and usage process of this utility model:

[0026] The sulfuric acid solution to be processed is injected into the processing tank 1 through the inlet pipe 6 at the top of the processing tank 1. Based on the pH value detection result of the sulfuric acid solution by the pH detection equipment, it is determined whether acid or alkali solution needs to be added to adjust the pH value. If acid needs to be added, the valve of the acid tank 4 is opened to allow an appropriate amount of acid to flow into the sulfuric acid solution in the processing tank 1 through the corresponding pipe. If alkali needs to be added, the valve of the alkali tank 3 is opened to allow alkali solution to flow in.

[0027] After adding an appropriate amount of acid or alkali solution, the motor 201 can be started. The output shaft of the motor 201 drives the rotating shaft 202 to start rotating. Since the locking block 204 is engaged with a set of locking slots 206 below, the rotating shaft 202 can drive the rotating rod 205 to rotate synchronously. At the same time, the insertion rod 207 at the bottom of the rotating rod 205 is engaged with the slot A209 at the bottom of the stirring rod 208. Therefore, the rotation of the rotating rod 205 will drive the stirring rod 208 to rotate together, stirring the sulfuric acid solution in the tank, so that the added acid or alkali solution is fully mixed with the sulfuric acid solution, accelerating the pH adjustment process.

[0028] After the sulfuric acid pH adjustment and stirring in processing tank 1 are completed, open the outlet pipe 5 at the bottom of processing tank 1 to discharge the sulfuric acid solution into the subsequent battery production process. Then, the operator can press the locking block 204, causing it to squeeze the connecting spring 203 and move it into the inner wall of the rotating shaft 202, disengaging it from the lower set of locking slots 206. At this time, the insert rod 207 below the rotating rod 205 disengages from the slot A209. Move the rotating rod 205 downwards until the set of locking slots 206 on the upper outer wall of the rotating rod 205 corresponds to the position of the locking block 204. Release the locking block 204; the connecting spring 203, due to its own elasticity, causes the locking block 204 to pop out and engage with the upper locking slot 206. At this time, the insert rod... 207 engages with slot B211; the motor 201 is restarted, and the rotating shaft 202 drives the rotating rod 205 to rotate. Since the rod 207 engages with slot B211 of the ring 210, the rotating rod 205 will drive the ring 210 to rotate. When the ring 210 rotates, the scraper 212 fixedly connected to its outer wall will move in a circle along the inner wall of the processing tank 1 with the movement of the ring 210. The scraper 212 is in close contact with the inner wall of the processing tank 1, scraping away impurities, residual acid or alkali attached to the inner wall of the processing tank 1. The device has a simple overall structure, and the switching operation between stirring and cleaning the inner wall is convenient. It does not require the operator to manually clean the inner wall, making it more convenient to use.
