[0033] First embodiment
[0034] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a ternary material mixer 100, comprising a tank 110, an agitator 120 and at least one static eliminator 130;
[0035] Each static eliminator 130 includes a static rod 131 and a static eliminator body 132. The static rod 131 is fixed to the inner wall of the tank 110. The static eliminator body 132 is arranged outside the tank 110. The static rod 131 is electrically connected to the static eliminator body 132.
[0036] The stirrer 120 includes a motor 190 and a stirring paddle. The stirring paddle (not shown) is located in the tank body 110. The motor 190 is disposed at the bottom of the tank body 110. The output end 141 of the motor 190 is connected to the stirring paddle.
[0037] The ternary material mixer 100 provided in this embodiment, due to the provision of the static eliminator 130, can enable the static electricity generated during the material mixing process in the tank body 110 to be conducted out and eliminated by the static rod 131, thereby reducing the local agglomeration of a single material, making the material mixing more uniform, shortening the working cycle of a single high-speed mixer, and improving production capacity.
[0038] Furthermore, the eliminator body 132 is disposed on the outer wall of the tank body 110 .
[0039] Furthermore, there are multiple static eliminators 130 , and the multiple static eliminators 130 are evenly distributed along the circumference of the tank body 110 .
[0040] Providing a plurality of static eliminators 130 and evenly distributing them along the circumference of the tank body 110 can fully discharge the static electricity generated in the tank body 110 .
[0041] Specifically, in a preferred embodiment, in order to fully eliminate static electricity, the number of static eliminators 130 provided may be, for example, 6.
[0042] Furthermore, the static eliminator 130 includes a 7-shaped connecting rod 133, one end of which is connected to the eliminator body 132, and the other end of which passes through a first through hole provided on the side wall of the tank body 110 and is connected to the static rod 131;
[0043] In order to ensure the sealing of the tank body 110 and avoid static electricity between the electrostatic rod and the side wall of the tube body, a first insulating sealing sleeve 134 is provided in the gap between the hole wall of the first through hole and the “7”-shaped connecting rod 133 .
[0044] Furthermore, the ternary material mixer 100 also includes a base 180 , and the tank body 110 is disposed on the base 180 .
[0045] Second embodiment
[0046] For matters not mentioned in this embodiment, please refer to the first embodiment.
[0047] like Figure 1 and Figure 2 As shown, the ternary material mixer 100 also includes a potential detector, which includes a detector body 150 and at least one detection rod 151. The detector body 150 is arranged outside the tank body 110, and one end of each detection rod 151 passes through the side wall of the tank body 110 and extends into the tank body 110. The detector body 150 and each detection rod 151 are electrically connected.
[0048] A potential detector is set to detect the electrostatic potential during the mixing process. According to the detected electrostatic potential information, the static eliminator 130 is adjusted to provide a corresponding potential. For example, if the electrostatic potential is detected to be a value a, the static eliminator 130 is adjusted to provide a corresponding -a value potential to just offset the static electricity in the tank.
[0049] The setting of the potential detector can not only provide potential information to the static eliminator 130 so that the static eliminator 130 can cooperate with the potential detection information setting to more fully eliminate static electricity, but also can timely detect whether the static eliminator 130 is damaged through the potential information.
[0050] Furthermore, the ternary material mixer 100 further includes an annular fixing frame 160, which is disposed at the lower portion of the outer wall of the tank body 110; there are multiple detection rods 151, which are disposed on the annular fixing frame 160, and the detector body 150 is electrically connected to each detection rod 151 through pre-buried wires in the annular fixing frame 160;
[0051] The ternary material mixer 100 further includes a wiring tube 153 , one end of which is connected to the detector body 150 , and the other end of which is connected to the annular fixing frame 160 . The wiring tube 153 contains wires for electrically connecting the detector body 150 and each detection rod 151 .
[0052] Third embodiment
[0053] For matters not mentioned in this embodiment, please refer to the second embodiment.
[0054] like Figure 1 and Figure 2 As shown, in this embodiment, the number of the static eliminators 130 is 6, the number of the detection rods 151 is 6, and the 6 detection rods 151 are arranged close to the 6 static rods 131 in a one-to-one correspondence.
[0055] Six static eliminators 130 and six detection rods 151 are provided to more fully eliminate static electricity, and the detection rods 151 are provided close to the static rods 131, that is, one detection rod 151 detects the potential near one static rod 131, so as to eliminate static electricity corresponding to different potentials of different static rods 131.
[0056] To ensure the sealing of the tank body 110 and avoid static electricity between the detection rod and the side wall of the tube body, the detection rod 151 extends into the tank body 110 through a second through hole set on the side wall of the tank body 110, and a second insulating sealing sleeve 152 is set in the gap between the hole wall of the second through hole and the detection rod 151.
[0057] Furthermore, the output end 141 of the motor 190 is fixedly sleeved with a static-eliminating ring 170. The static-eliminating ring 170 is connected to a static-eliminating device (not shown) outside the tank body 110.
[0058] Since static electricity is generated by the friction of the stirring paddle during the stirring process, the static electricity generated can be promptly discharged and eliminated by setting the static electricity removal ring.
[0059] In summary, the ternary material mixer 100 provided in the embodiment of the utility model, due to the setting of the static eliminator 130, can enable the static electricity generated during the material mixing process in the tank body 110 to be discharged and eliminated by the static rod 131, thereby reducing local agglomeration of single materials, making the materials mixed more evenly, shortening the working cycle of a single high-speed mixer, and improving production capacity.
[0060] In some embodiments, the ternary material mixer 100 is also provided with a potential detector. The potential detector cooperates with the setting of the static eliminator 130 to not only provide potential information for the static eliminator 130, so that the static eliminator 130 cooperates with the potential detection information setting to more fully eliminate static electricity, but also can promptly detect whether the static eliminator 130 is damaged through the potential information.
[0061] In some embodiments, the provision of the anti-static ring 170 can further eliminate static electricity generated during the mixing process.
[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
