Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as Figure 1-5 as shown in figure 1 As shown, the structure of the paint stirring paddle is as follows: a stirring shaft 10 is welded at the middle of the disc 20, and six curved paddles 30 are uniformly welded along the circumference of the disc, and the paddles are symmetrically distributed about the stirring shaft. figure 2 It is a shape structure diagram of a curved paddle, and there is a square socket 310 on the paddle, so that the paddle 30 can be installed and welded on the disc 20 .

[0025] The car paint stirring paddle adopts a curved paddle, which is improved on the basis of a six-blade turbine paddle, and the paddle is changed from a flat paddle to a curved paddle. The longitudinal section of the curved blade 30 designed by the present invention is formed by lofting two symmetrical original blade shapes rota...

Abstract

The invention provides a novel car paint stirring paddle, which includes a central stirring shaft, the stirring shaft is coaxially fixedly connected with a disc, and the disc is uniformly fixedly connected with paddles along the outer peripheral side, and the longitudinal section of the paddles is Blade type, the outer circumference of the blade is a curved surface, and the middle part of the blade has a socket inserted into the disc and fixedly connected with the disc. The structure of the blade is to change the plane blade into a curved blade. From the flow field simulation results Compared with the original paddle, a larger shear rate and a stronger main body convection and diffusion capacity can be obtained with lower energy consumption.

Description

technical field [0001] The invention relates to a novel car paint stirring paddle. Background technique [0002] Stirrer is a device for forced convection and uniform mixing of liquid and gaseous media. The car paint stirrer is used to complete the stirring operation of the car paint, prevent the precipitation of solute, disperse the gas in the stirring tank, and achieve the purpose of uniform stirring. [0003] There are many types of agitators, mainly propeller agitators, pusher agitators, turbine agitators, anchor agitators and so on. [0004] At present, there is no mixing system capable of mixing and mixing operations in all fields, because the design and optimization of mixing systems are generally only for specific operating objects, conditions and operating processes. The design and research of agitator specially used for automotive paint mixing has rarely appeared at present, and the design and development of car paint agitator needs to be developed. The structur...
