Technical Field

[0001] The utility model relates to the field of sulfuric acid circulation tanks, in particular to a refined sulfuric acid circulation tank for preparing sulfuric acid for lead-acid batteries. Background Art

[0002] Sulfuric acid and metal in lead-acid batteries form a primary cell, causing electrons to move in a directed manner to form an electric current. When preparing sulfuric acid, in order to control the acid concentration at a normal value, it is generally necessary to dilute the sulfuric acid in the circulation tank with water.

[0003] The existing Chinese patent publication number is: CN218600065U, which provides a refined sulfuric acid circulation tank for preparing sulfuric acid for lead-acid batteries, including a reaction tank, a cooling tank fixedly connected to the bottom of the reaction tank, a water pump fixedly connected to the bottom of the cooling tank, a water inlet pipe fixedly connected to one side of the water pump, a feeding pipe fixedly connected to one side of the reaction tank, and a fixed plate fixedly connected to the bottom of the reaction tank. The utility model has a good heat dissipation effect of the device through the coordination of structures such as the reaction tank, the cooling tank, the water pump, the diverter plate, the drainage block and the rotating rod, and the sulfuric acid is evenly dispersed through the partition plate. The water inside the cooling tank is blocked by the drainage block, so that the dilute sulfuric acid can flush the partition and drive the rotating rod to rotate. The rotating rod drives the fan blade to rotate, and the dilute sulfuric acid contacts the partition. The heat dissipation effect of the device is good through the coordination of structures such as the reaction tank, the cooling tank, the water pump, the diverter plate, the drainage block and the rotating rod.

[0004] The above-mentioned sulfuric acid tank also has the following problems during use: when the above-mentioned sulfuric acid circulation tank is in use, it takes some time for the sprayed water droplets to be fully mixed with the sulfuric acid after entering the sulfuric acid solution, resulting in a low overall dilution efficiency.

[0005] Therefore, it is necessary to invent a refined sulfuric acid circulation tank for preparing sulfuric acid for lead-acid batteries to solve the above problems. Utility Model Content

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a refined sulfuric acid circulation tank for preparing sulfuric acid for lead-acid batteries, comprising a circulation tank body and a block, a liquid inlet pipe is fixedly inserted at the top of the circulation tank body, and an air outlet valve pipe and an acid liquid outlet pipe are sequentially arranged on the side of the circulation tank body, a motor is fixedly connected to the top wall of the circulation tank body, and a screw is transmission-connected to the output shaft of the motor, and the lower end of the screw is rotatably connected to the bottom wall of the circulation tank body, a movable block is threadedly sleeved on the outer ring of the screw, and a limit rod is movably inserted in the movable block, both side walls of the movable block are rotatably connected to a rotating shaft, and a stirring blade is fixedly sleeved on the outer wall of the rotating shaft, and a gear is fixedly inserted on the outer wall of the rotating shaft, and the gear is meshingly connected to the rack.

[0009] Preferably, the two limit rods pass through both sides of the movable block, and the outer wall of the limit rod is in contact with the inner wall of the through hole in the movable block and is slidably connected up and down. Under the limitation of the two limit rods, the movable block can synchronize the forward and reverse rotation of the screw to move up and down.

[0010] Preferably, the rotating shaft is in a "T" shape, and the "T"-shaped end of the rotating shaft is rotatably connected to a rotating groove reserved in the movable block, so that the rotating shaft is rotatably connected to the movable block.

[0011] Preferably, the surface of the block is fixedly connected to a limit block, and the outer wall of the limit block is slidably connected up and down with the inner wall of the strip groove reserved in the groove body of the circulation groove main body close to the limit block, ensuring that both sections are limited when the entire shaft moves up and down, so that the up and down movement and rotation of the shaft will not be biased.

In this way, when the two gears descend and mesh with the racks, the two gears turn in different directions, thereby causing the two stirring blades to stir in different directions, thereby achieving a better mixing effect for the liquid inside the circulation tank body.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. The utility model starts the motor to adjust the screw to rotate. At this time, the movable block connected with the screw thread moves up and down under the limit of two limit rods.

[0015] 2. At the same time, the two racks are respectively meshed and connected with different sides of the two gears inserted on the two rotating shafts. This makes it possible for the two gears to rotate in different directions when they descend and mesh with the racks, thereby causing the two stirring blades to stir in different directions, so that the liquid mixing and dilution effect inside the circulation tank body is better.
