Description

Technical Field

[0001] This utility model relates to the field of treatment device technology, specifically a corrosion-resistant treatment device for multi-stage pump blades. Background Technology

[0002] As one of the core components of a multistage pump, the blades are mainly distributed on the impeller. They propel the fluid through the centrifugal force generated by the impeller's rotation, making them a key component for fluid transport and pressurization. During operation, the blades are in direct contact with the fluid. To increase their service life, corrosion-resistant treatment is usually required. A common method is to spray a protective coating, such as epoxy resin or polyurethane, onto the blades. However, the conventional spraying method typically involves spraying one side of the blade first, then the other, followed by drying. This method has low spraying efficiency and results in deficiencies in the corrosion resistance treatment of the blades. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a multi-stage pump blade corrosion-resistant treatment device. The device uses an immersion method to treat the blade surface for corrosion resistance. This method can not only improve the treatment efficiency but also reduce the leakage on the blade surface. After immersion, excess coating liquid is blown away by airflow to avoid waste of coating liquid. After coating the blade surface, the coating can also be dried. At the same time, the continuous feeding and discharging method is used to treat the blade for corrosion resistance, which further accelerates the blade treatment efficiency and can effectively solve the problems in the background technology.

An opening is opened on the upper side of the treatment box 1 corresponding to the position of the turntable 3. It should be noted that the air gripper assembly 4 adopts the prior art and is mainly composed of an air pump, an air pipe and air grippers. The air pump draws air from or injects air into the air grippers through the air pipe to realize the opening and closing of the air grippers.

[0017] In use, the blades are clamped by closing the grippers in the gripper assembly 4. Then, the drive assembly drives the turntable 3 to rotate, so that the gripper assembly 4 enters the processing box 1 through the opening and immerses the blades in the coating liquid. The coating liquid covers the outside of the blades for corrosion resistance treatment. The immersion treatment method has higher processing efficiency and coverage than spraying, ensuring the quality of blade processing. At the same time, the turntable 3 is used for continuous feeding and discharging of blades, improving blade processing efficiency.

An air supply assembly is provided on the side of the treatment box 1, which communicates with the inner cavity of the jet box 6. Air is injected into the jet box 6 through the air supply assembly. The gas entering the jet box 6 is ejected through the jet nozzle. The airflow acts on the blade to blow away excess coating liquid, and the blown-away coating liquid flows back into the treatment box 1 through the opening, reducing the waste of coating liquid. The jet assembly facilitates the drying of the coating liquid wrapped on the blade by blowing away excess coating liquid.

[0019] The air supply assembly includes an air pump group 7 installed on the side of the processing box 1.

Several sets of heating groups 13 are installed on the positioning frame 12, which are arranged sequentially from top to bottom. The heating groups 13 include, but are not limited to, electric heating plates, electric heating lamps, or electromagnetic induction heaters. When the air gripper group 4 clamps the blade and passes it between the two sets of positioning frames 12, the heating group 13 works to dry the coating on the blade, thereby improving the efficiency of the corrosion resistance treatment of the blade. After drying, the air gripper in the air gripper group 4 is opened, and the blade can be removed from the air gripper group 4.

[0022] The drive assembly includes a motor unit 5 mounted on the side of the mounting frame 2. The output shaft of the motor unit 5 is fixedly connected to the center of the turntable 3.
