A device for adjusting the concentration of sulfuric acid for preparing sulfuric acid for batteries

Abstract

This application provides a sulfuric acid concentration modulation tool for preparing battery-specific sulfuric acid, relating to the field of battery manufacturing. The tool includes an outer barrel, a sealing mechanism, and a controller. A distribution mechanism is connected to the top of the sealing mechanism. The distribution mechanism includes a distribution pipe and a driven gear, with the distribution pipe located inside the outer barrel. Through the distribution mechanism, a solenoid valve controls the opening of the feed pipe, allowing material to flow from the feed pipe into the distribution pipe along a conical hopper. The output shaft of a second motor inside a fixed box rotates, driving the main gear at the bottom of the shaft to rotate. The main gear then drives the driven gear to rotate. Under the constraint of a fixed plate and a limiting ring, the driven gear rotates, causing the distribution pipe to rotate stably and the material to flow down at a uniform speed. This avoids accelerated damage to some material contact surfaces, extends the service life of the modulation tool, reduces maintenance costs, and improves the cost-effectiveness of the tool.

Description

Technical Field

[0001] This application relates to the field of storage battery technology, specifically to a sulfuric acid concentration modulation tool for preparing storage battery-specific sulfuric acid. Background Technology

[0002] Sulfuric acid is a highly reactive dibasic inorganic strong acid, reacting with most metals. High-concentration sulfuric acid is strongly hygroscopic and can be used as a dehydrating agent; when mixed with water, it releases a large amount of heat. It possesses strong corrosive and oxidizing properties, making it an important industrial raw material used in the manufacture of fertilizers, storage batteries, and widely applied in petroleum purification and metal smelting. With the rapid development of my country's new energy industry, lead-acid batteries currently hold the largest market share and widest application among chemical batteries, resulting in a very large market demand for refined battery sulfuric acid. The production process of lead-acid batteries requires equipment for preparing specialized battery-grade sulfuric acid through sulfuric acid concentration modulation.

[0003] Patent No. CN220194833U discloses a sulfuric acid concentration modulation tool for preparing sulfuric acid for storage batteries. This tool is equipped with a liquid guide shell, a liquid outlet, and a liquid baffle. It uses a solenoid valve to control the supply of materials, thereby controlling the reaction rate. The distribution of the liquid outlet and the liquid baffle ensures that the materials are supplied evenly, allowing them to reach the reaction site along the inner wall, facilitating the reaction, making the reaction mild, preventing damage to the equipment, eliminating the generation of a large amount of heat in the same location, and preventing local overheating and boiling.

[0004] However, although the powder mechanism of the sulfuric acid concentration modulation tool for preparing battery-specific sulfuric acid achieves the purpose of uniform material distribution, the relatively fixed position of the liquid outlet and the contact surface of the separator causes the material to react in the same position. Under the influence of heat accumulation, there is still some damage to the contact surface of the separator, which reduces the service life of the modulation tool and reduces its cost-effectiveness. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this application provides a sulfuric acid concentration modulation tool for preparing battery-specific sulfuric acid, which solves the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this application provides the following technical solution: a sulfuric acid concentration modulation apparatus for preparing battery-specific sulfuric acid, comprising an outer barrel, a closing mechanism for controlling the up-and-down movement of the barrel lid, and a controller for controlling the operating status of each device in the modulation apparatus. The top of the closing mechanism is connected to a distribution mechanism to prevent sulfuric acid from reacting in the same location. The distribution mechanism includes a distribution pipe and a driven gear. The distribution pipe is disposed inside the outer barrel, and the center of the driven gear is connected to the upper side of the distribution pipe. The closing mechanism is connected to the lower left side of the outer barrel, and the controller is connected to the front side of the closing mechanism.

[0009] By adopting the above technical solution, the rotation of the gear can drive the rotation of the distribution pipe, thereby causing the material to flow down the inner wall of the outer barrel for uniform mixing, avoiding the continuous exposure of the heat generated by the reaction in a fixed position.

[0010] Preferably, the dispensing mechanism further includes a feed pipe and a solenoid valve, the feed pipe being connected to the lower side of a sealing mechanism, and the solenoid valve being connected to the upper side of the feed pipe.

The top of the fixed frame is connected to the bottom left side of the gear, and a rotating rod is connected to the bottom of the fixed frame. Mixing plates are evenly connected to the side of the rotating rod. One end of the discharge pipe is connected to the lower right side of the outer barrel, and a solenoid valve is provided on the surface of the discharge pipe.

[0017] By adopting the above technical solution, the rotation of the gear drives the rotation of the fixed frame, which in turn drives the rotation of the mixing plate on the surface of the rotating rod to stir and mix the materials. Furthermore, the discharge pipe equipped with a solenoid valve facilitates the discharge of the mixed materials and the cleaned wastewater.

[0018] Preferably, the sealing mechanism includes a connecting frame and a first motor.

[0019] By adopting the above technical solution, the output shaft of the first motor at the top of the connecting frame can be used to drive the screw to rotate, providing power support for the operation of the sealing mechanism and ensuring the stability of the screw's operation.

[0020] Preferably, the closing mechanism further includes an L-shaped plate and a sliding groove. The L-shaped plate is disposed on the right side of the connecting frame.

The inner wall of the sliding groove is slidably connected to the side of the slider.

[0021] By adopting the above technical solution, the sliding connection between the slider and the groove can be used to convert the rotation of the screw driving the L-shaped plate with threaded holes into up and down movement, and reduce the possibility of misalignment when the top cover and the top of the outer barrel are attached.

[0024] (III) Beneficial Effects

[0025] This application provides a sulfuric acid concentration modulation tool for preparing sulfuric acid specifically for storage batteries. It has the following beneficial effects:

[0026] 1. This sulfuric acid concentration modulation fixture for preparing battery-specific sulfuric acid, through the setting of a distribution mechanism, uses a solenoid valve to control the opening of the feed pipe. After the feed pipe is opened, the material flows into the distribution pipe from the feed pipe along the conical hopper. The output shaft of the second motor in the fixed box rotates, driving the main gear at the bottom of the shaft to rotate. The rotation of the main gear drives the driven gear to rotate. Under the restriction of the fixed plate and the limit ring, the rotation of the driven gear drives the distribution pipe to rotate stably, and the material flows down at a uniform speed. This avoids the accelerated damage of some material contact surfaces, extends the service life of the modulation fixture, reduces maintenance costs, and improves the cost-effectiveness of the modulation fixture.

[0027] 2. This sulfuric acid concentration modulation fixture for preparing battery-specific sulfuric acid, through the setting of a closed mechanism, has a first motor output shaft at the top of the connecting frame rotating to drive the screw to rotate. The rotation of the screw drives the L-shaped plate with threaded holes to move down. The movement of the L-shaped plate drives the top cover to move down until the bottom of the sealing ring is in contact with the top of the outer barrel. At the same time, it drives the slider to move down in the slide groove. This avoids the need for manual opening or closing of the top cover, reduces the possibility of the reaction gas inside the outer barrel causing harm to the workers, and improves the safety of using the modulation fixture.
