Description

Technical Field

[0001] This utility model relates to the field of metal powder cleaning technology, and in particular to a stirring cleaning machine for cleaning metal powder. Background Technology

[0002] Metal powder, defined as an aggregate of metal particles smaller than 1 mm, encompasses single metal powders, alloy powders, and powders of several refractory compounds with metallic properties, constituting the core raw material of powder metallurgy technology. The stirred cleaning machine, specifically designed for cleaning metal powders, mainly consists of a base, lifting rod, lifting platform, stirring motor, and stirring device. During operation, the stirring device is placed inside the cleaning tank, positioned above the base, and driven by the stirring motor. The stirring rod then drives the stirring device to perform the cleaning task on the metal powder. This cleaning machine, with its simple structure, convenient operation, high cleaning efficiency, and easy control, is particularly suitable for large-scale production of metal powders.

[0003] Specifically, the agitator-type cleaning machine achieves precise control over the cleaning process by configuring a liquid level control system, an internal circulation filtration system, an automatic temperature control heating system, and a variable frequency speed regulation system, ensuring cleaning quality and efficiency. Simultaneously, this equipment can complete spraying, rough washing, fine cleaning, rinsing, rust prevention, drying, and atomized oil spraying in one operation, meeting the diverse needs of metal powder cleaning.

[0004] In the cleaning process of metal powder, although stirred cleaning machines can effectively mix the cleaning solution and powder to achieve the cleaning goal, after the metal powder and cleaning solution are mixed in the cleaning chamber, the powder and cleaning solution need to be separated after cleaning. This process usually requires additional equipment or steps, such as filtration, centrifugation, or sedimentation, which not only increases the complexity of the operation but may also cause the powder to be recontaminated during the separation process.

[0005] The chemical components in cleaning solutions, such as moisture, acids, and alkalis, can react with metal powders, leading to oxidation on the powder surface. Prolonged contact will undoubtedly exacerbate this oxidation reaction, thus affecting the quality and performance of the metal powders. This is especially true for highly reactive metal powders sensitive to oxidation, such as titanium and aluminum powders; excessive contact with cleaning solutions can lead to even more serious consequences. Utility Model Content

[0006] The main objective of this invention is to provide a stirring cleaning machine for cleaning metal powder, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A stirring cleaning machine for cleaning metal powder includes a base frame, side frames, a fixed base, a reducer, and a servo motor. Two of the side frames are mounted on the base frame, the fixed base is mounted on one of the side frames, and the reducer and servo motor are mounted on the fixed base.

[0009] The two side frames are respectively connected to a connecting shaft and a docking shaft via bearing assemblies. The connecting shaft is connected to the output end of the reducer. A support frame is connected between the connecting shaft and the docking shaft. The support frame is connected to a stirring and cleaning cylinder via clamps. A sealing cap is connected to the opening of the stirring and cleaning cylinder. A feed pipe is provided at the upper end of the sealing cap.

The powder discharge pipe is used to discharge the metal powder inside the inner cylinder, and the liquid discharge pipe discharges the liquid inside the stirring and cleaning cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The centrifugal stirring cleaning mechanism, through the precise coordination of a servo motor and reducer, drives the stirring cleaning drum and inner cylinder to achieve efficient rotary cleaning. This rotary cleaning method can thoroughly stir the metal powder, ensuring full contact with the cleaning liquid, thereby effectively removing dirt and impurities from the powder surface. Simultaneously, the rational design of the material inlet and outlet system ensures smooth flow of metal powder and cleaning liquid, further improving cleaning efficiency. Under the action of centrifugal stirring, the metal powder can be evenly dispersed in the cleaning liquid, avoiding powder agglomeration and sedimentation. Furthermore, multiple drainage holes on the inner cylinder facilitate the rapid discharge of cleaning liquid, ensuring that no residual liquid affects cleaning quality. The separate installation of powder discharge pipes and liquid discharge pipes also ensures complete separation of metal powder and cleaning liquid, thereby improving cleaning quality.

[0018] The equipment features a well-designed material feeding and discharging system. Users simply need to feed the metal powder to be cleaned into the mixing and cleaning drum through the feed pipe and start the servo motor to begin the cleaning process. After cleaning, the metal powder and cleaning liquid can be easily discharged through the powder discharge pipe and liquid discharge pipe, making operation simple and quick.

[0019] The rational design of the centrifugal mixing cleaning mechanism and material feeding / discharging system ensures the stability and durability of the equipment. During the cleaning process, all components work precisely together to effectively transmit power, avoiding equipment failures caused by loose or worn parts. At the same time, the overall structure of the equipment is compact and robust, capable of withstanding large workloads and ensuring long-term stable operation. Attached Figure Description
