Problems solved by technology

The biggest disadvantage of this kind of planetary ball mill is that since the carbon plug is fixed on the carbon plug frame and is in contact with the copper sleeve surrounding the copper sleeve frame, this structure makes it difficult to separate and insulate the carbon plug and the copper sleeve from the frame, and cannot guarantee the electrical conductivity of the equipment. Safety. At the same time, the gap between the carbon plug and the carbon plug holder is generally large, and the contact angle and strength between the carbon plug and the copper sleeve are difficult to control. The equipment will inevitably vibrate during the operation of the ball mill. Continuous vibration with a certain intensity will easily lead to the dislocation of the carbon plug. , serious wear and tear or even breakage, the transmission motor will be burned due to lack of phase, and even the whole equipment will cause serious electric leakage accidents

Embodiment 1

[0019] Example 1, such as figure 1 , 2 As shown, an omnidirectional planetary ball mill includes a rotating frame 1, a transmission motor 9, a planetary transmission mechanism 10, a grinding tank 12, and a grinding tank seat 13; the transmission motor 9 drives the planetary transmission mechanism 10 through a pulley 2, and the planetary transmission The mechanism 10 drives the grinding tank 3 to rotate through the grinding tank seat 4; the rotating frame 1 fixes the planetary transmission mechanism 10, and is supported by the bearing seats 12 at both ends. The motor gear 8 and the large gear 5 are driven to make the upper mechanism of the entire rotating frame 1 perform a 360° flip movement, which is characterized in that it also includes a through-hole slip ring 6 placed at the other end of the rotating frame 1 shaft. The through-hole slip ring includes The stator f and the rotor g, the three terminal wires A, B, and C of the transmission motor 9 are respectively connected w...

Embodiment 2

[0020] Example 2, such as figure 1 , 2 As shown, on the basis of Embodiment 1, the connection method of the through-hole slip ring 6 and the transmission motor 9 is as follows: first, the input power is connected to the stator wires a, b, and c, and the rotor wires a1, b1, and c1 lead from the large gear 5. Go through the counterbore of the main shaft on the rotating frame 1, and connect the wires A, B, and C of the transmission motor 9 terminals to conduct, and the set screw d is used to pass through the slip ring inner hole and cooperate with the rotating frame shaft to prevent rotation; the slip ring The stator anti-rotation pin shaft e prevents the through-hole slip ring stator from rotating.

Embodiment 3

[0021] Embodiment 3, on the basis of Embodiment 1, the number of the grinding pots 3 is 4, the grinding pot seat 4 and the grinding pot 3 are fixed by the clamping device 11, and the grinding pot seat 4 and the planetary mechanism 10 are fixed by a tapered shaft or a flange form connection.

[0022] The outstanding advantage of the present invention is that the mechanism on the rotating frame 1 can be ball milled and mixed in any angle of 360°. Due to the application of the through-hole slip ring in the present invention, the omnidirectional planetary ball mill solves the problem of traditional planetary ball mill grinding tanks. After a certain ball milling time, the internal materials sink to the bottom, agglomerate, stick to the wall, etc., and at the same time meet the nano-level requirements required by customers, saving costs. At the same time, it also solves the following safety problems in the use of the original collector ring in the traditional ball mill: the origina...

Description

technical field [0001] The invention relates to a ball mill, in particular to an omnidirectional planetary ball mill. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. It is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizers, black and non-ferrous metal beneficiation, glass ceramics and other production industries, for dry or wet grinding of various ores and other grindable materials. As the application fields of ball mills are becoming more and more extensive, and the requirements for materials in various fields are getting higher and higher, so higher requirements are put forward for the operation stability of ball mills, the speed of ball mills, the safety of ball mills, and the continuous running time of ball mills. [0003] The patent developed by the applicant in the early stage, the application number CN201220189936.X, the patent name is a high-temp...
