Double-cone mixer

Abstract

The invention relates to a double-cone mixer which comprises a mixing cylinder, a machine frame for supporting the mixing cylinder and a mixing cylinder driving mechanism, wherein the mixing cylinder driving mechanism comprises a motor, a worm gear reducer, a rotating shaft and a bearing carrier; the motor drives the worm gear reducer to operate, the worm gear reducer is connected with the rotating shaft in a transmission mode, and the rotating shaft penetrates through the bearing carrier and drives the mixing cylinder to rotate; the double-cone mixer is also provided with a cut-off valve, an air bag, an explosion-proof electromagnetic pulse valve, an injection pipe and an air cannon stirring bracket which are contained in an air cannon unblocking device; the inside of the air cannon stirring bracket is hollow; an air outlet of the cut-off valve is connected with an air inlet of the air bag; an air outlet of the air bag is connected with an air inlet of the explosion-proof electromagnetic pulse valve; one end of the injection pipe is connected with an air outlet of the explosion-proof electromagnetic pulse valve; the other end of the injection pipe communicates with the air cannon stirring bracket; and a plurality of air holes are arranged outside the air cannon stirring bracket. The double-cone mixer implements automatic control, is convenient to operate, enhances the production efficiency, lowers the noise, prolongs the service life of the mixing cylinder and ensures the safety of operators.

Description

technical field [0001] The invention relates to the technical field of mixers, in particular to a double-cone mixer. Background technique [0002] Double cone mixer is a kind of mixer, which is often used to fully mix various powder or granular materials. During the mixing process, the mixing barrel of the mixer continuously rotates to achieve the mixing effect. [0003] The powder making process of NdFeB magnets requires the use of double cone mixers for fine powder mixing to improve the uniformity of the powders, thereby creating favorable conditions for the high performance of the final product. However, during the feeding process, due to the excessively large cone angle of the hopper and the agglomeration of the powder, the powder diameter is too small and the friction coefficient is large, the friction coefficient between the powder and the warehouse wall is large, the feeding height is large, and the powder at the bottom is compacted by excessive feeding, etc. Due to...

Problems solved by technology

However, during the feeding process, due to the excessively large cone angle of the hopper and the agglomeration of the powder, the powder diameter is too small and the friction coefficient is large, the friction coefficient between the powder and the warehouse wall is large, the feeding height is large, and the powder at the bottom is compacted by excessive feeding, etc. Due to various influences, the fine powder remains in the mixer. Not only that, the powder is prone to bridging when it is discharged, which will cause the bonded warehouse wall to block the discharge port. The traditional method is to use a human mallet to strike the material. , this method will not only produce a lot of noise, but also time-consuming and labor-intensive, resulting in low production efficiency, and also damage the life of the barrel, and even cause a certain danger to the operator
