Description

Technical Field

[0001] This utility model relates to the field of chemical machinery technology, specifically a high-speed dispersing agitator for the production of porous microsphere calcium silicate. Background Technology

[0002] High-speed dispersing agitators are a common type of equipment in chemical production, typically used for mixing and pulverizing powdered materials. Powdered materials need to be completely and uniformly dispersed in the liquid phase. The industry generally uses disc-shaped sawtooth agitators, which, while possessing strong radial dispersion and shearing capabilities, suffer from poor axial circulation, severe material stratification, and uneven material distribution within the vessel, failing to achieve the required complete and uniform dispersion. Therefore, a new agitator structure is needed that can simultaneously achieve axial circulation and radial dispersion. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] As per the instruction manual Figure 1-3As shown, a high-speed dispersing mixer for producing porous microsphere calcium silicate includes a body 15. A feeding pipe 10 is connected to the top of the body 15, and a discharge pipe 9 is provided at the bottom of the body 15. A stirring shaft 13 is provided inside the body 15. The upper end of the stirring shaft 13 passes through the middle of the top of the body 15 and extends to the outside to connect with a reducer 3. The lower end is inserted into a fixing device 14. The upper part of the reducer 3 is connected to the output shaft of a drive motor 1. A speed measuring code disk 2 is connected between the drive motor 1 and the reducer 3. A bracket 4 is vertically connected to the left side of the reducer 3. A photoelectric sensor 5 is fixedly connected to one side of the upper end of the bracket 4. The edge of the speed measuring code disk 2 is provided with several teeth 2-1. The teeth 2-1 are located in the middle of the photoelectric sensor 5 and cooperate with the photoelectric sensor 5. A first dispersing disc mixer 7 and a second dispersing disc mixer 8 are respectively connected to the outside of the stirring shaft 13. The first dispersing disc mixer 7 is bent upward and the second dispersing disc mixer 8 is bent downward. Several blades are fixed on the surface of the first dispersing disc mixer 7 and the second dispersing disc mixer 8 respectively.

[0017] As per the instruction manual Figure 1-3 As shown, in the above structure, the first dispersing disc agitator 7 and the second dispersing disc agitator 8 are respectively curved upward and downward, and both have blades fixedly distributed on their outer surfaces along the bending direction of the disc surface. When rotating, due to the curved shape, they can play an axial circulation role. The number and spacing of the dispersing discs can also be adjusted according to actual needs.

[0018] In this embodiment, a frame stirrer 6 is also provided on the side of the stirring shaft 13. The frame stirrer 6 is located outside the first dispersion disc stirrer 7 and the second dispersion disc stirrer 8. The frame stirrer 6 increases the radial stirring effect of the stirrer.

[0019] In this embodiment, a first discharge valve 11 and a second discharge valve 12 are connected to the side of the discharge pipe 9. The dual valves can prevent backflow and enhance control, effectively preventing fluid backflow and enhancing control over fluid flow.

[0020] As per the instruction manual Figure 1-3 As shown, the fixture 14 includes a fixing frame 14-1 and a groove 14-2. The fixing frame 14-1 is fixedly connected to the inner bottom surface of the machine body 15. The fixing frame 14-1 is located outside the discharge pipe 9 and does not affect the discharge. The groove 14-2 is fixed above the fixing frame 14-1, and the end of the stirring shaft 13 is inserted into the groove.

[0021] In this invention, the mixer is equipped with a controller. A photoelectric sensor in the structure sends the number of revolutions (n) measured within a certain time period to a processor. The processor calculates the rotational speed based on this data and the radius of the speed encoder, and displays the result on the controller's interface. The mixer's rotational speed can be adjusted via the controller. Using a photoelectric sensor provides more accurate testing and improves control precision.
