Description

Technical Field

[0001] The present invention belongs to the technical field of immersion circulating pumps, and in particular relates to an automated stamping processing system and method for an immersion circulating pump stirring head. Background Art

[0002] The agitator plays a key role in submerged circulation pumps. Its main functions are: 1) The agitator's rotation generates shear forces and vortexes, breaking down liquid stratification and promoting uniform mixing of different components. In submerged circulation pumps, the agitator works synergistically with the pump's circulating flow to significantly improve mixing efficiency. For example, when the pump extracts and refills liquid, the agitator's rotation accelerates local turbulence, resulting in more thorough mixing. This is particularly useful for slurries with high viscosity or solids. 2) For slurries containing suspended particles (such as wastewater treatment or desulfurization slurries), the continuous agitation of the agitator prevents solid particle settling and reduces the risk of pump and pipeline blockage. For example, slurry circulation pumps use agitators to maintain particle suspension, ensuring stable delivery. Agitator impellers made of wear-resistant materials extend their service life and are suitable for highly corrosive environments. 3) Optimized agitator design can reduce the energy consumption of the circulation pump. For example, low-speed submerged agitator pumps use large impellers to generate strong thrust, reducing motor load; while magnetically driven agitators utilize contactless transmission to reduce friction losses and improve energy efficiency. Mechanically sealed or magnetically sealed mixing heads can avoid leakage and ensure long-term stable operation of the system.

[0003] Traditional mixing heads for immersion circulation pumps are mostly mixing heads with spiral blades. The spiral blades are difficult to process and require six steps of turning, flanging, shaping, stamping, welding, and cleaning. This results in a high manufacturing cost for the mixing head, which is expensive for a component that needs to be replaced frequently. At the same time, the mixing head cannot prevent the filter holes on the pump cover from being blocked and cleaned during operation. To this end, our company has designed a combined mixing head for immersion circulation pumps, which has a low manufacturing cost and can prevent the filter holes on the pump cover from being blocked and cleaned. In the existing technology, there is a lack of an automated stamping processing system that can meet the production and assembly requirements of the above-mentioned combined mixing head, which affects the production efficiency of the mixing head.
