Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lead wastewater treatment equipment, in particular to a lead-containing wastewater treatment equipment and method for lead-acid battery production. BACKGROUND

[0002] A large amount of lead-containing wastewater is generated in the production process of lead-acid batteries. If such wastewater is directly discharged, it will pose a persistent threat to surface water and groundwater environments and eventually seriously endanger human health through food chains and other pathways. Therefore, before the wastewater is discharged, it must be strictly purified using professional treatment equipment and processes. Among them, adding chemical agents to the treatment tank containing wastewater to react with lead ions is a widely used core treatment method.

[0003] In the prior art, in order to promote the full reaction of chemical agents and wastewater, a stirring mechanism is generally installed inside the treatment tank or treatment tank. Through mechanical stirring, the agents can be quickly and uniformly dispersed in the entire water body, avoiding uneven local reaction, thereby ensuring rapid and complete reaction. At the same time, to avoid the flocculent precipitate formed after the reaction from being discharged with the water flow, a common measure is to set a filter plate in the treatment tank to intercept it, thereby effectively reducing the impurity content in the discharged water and ensuring the smooth progress of the subsequent treatment process.

[0004] However, in actual application, the above-mentioned method still has room for optimization. Although the stirring mechanism can achieve liquid mixing, part of the flocculent precipitate generated during stirring is easily adhered to the inner wall of the treatment tank or reaction tank. Long-term accumulation requires operators to stop for cleaning, affecting the continuous processing progress and overall efficiency. In addition, during the discharge stage of the treated water, due to the smaller diameter of the drainage pipeline compared to the treatment tank body, the water flow velocity and direction change, and some flocculent precipitate will accumulate and stay in the pipeline for a long time, causing pipeline blockage and affecting drainage efficiency. Manual intervention is required for dredging, increasing the complexity of maintenance and reducing dredging efficiency. Therefore, the present application proposes a lead-containing wastewater treatment equipment and method for lead-acid battery production to solve the above problems. SUMMARY

After the chemical agent is added to the treatment tank (1) through the feeding pipe (15), the main shaft (3) and the stirring shaft (7) are driven to rotate by the first driving assembly, so that the rotating disc (4) is intermittently rotated under the transmission of the transmission assembly, and the rotating disc (4) drives the scraper (6) fixedly connected to one end of the connecting rod (5) to move along the inner wall of the treatment tank (1) in a circular manner, so as to clean the impurities adhered to the inner wall of the treatment tank (1) during processing. At the same time, the rotation of the plurality of stirring shafts (7) drives the rotation of the plurality of stirring blades (8), so that the chemical agent and the wastewater are fully mixed, and the treatment effect is improved. After the reaction is completed, the sealing plug-in plate (10) is removed, the external pump body is communicated with the drain pipe (11), and the treated wastewater is discharged, and the precipitated impurities are intercepted in the filter box (9).

10. A method of treatment for a leaded wastewater treatment plant for the production of lead acid batteries according to claim 9, characterized in that: After the support box (2) is used for a period of time, part of the flocculent precipitate inevitably stays and accumulates in the drain pipe (11). The pipeline connected with the drain pipe (11) and the pump body is disassembled. First, the synchronous air cylinder (29) is controlled to drive the connecting plate (30) to move upward until the dredging rod (12) is coaxial with the drain pipe (11), and then the second driving assembly is started to drive the dredging rod (12) to move close to the inside of the drain pipe (11). At the same time, the dredging rod (12) rotates through the sliding cooperation of the spiral protrusions on the outer surface of the dredging rod (12) and the spiral grooves on the inner surface of the support seat (32), and then realizes horizontal movement while rotating, and further realizes cleaning the inner wall of the drain pipe (11) while pushing the deposited impurities into the support box (2) and falling into the collecting cylinder fixedly arranged at the bottom of the support box (2), which is convenient for subsequent collection.
