(13) The noise in the working process is small, and the creak generated by mutual friction of the grinding discs is avoided, so that the creak is difficult to enter the pointed sound of the ear.

(14) The machine is provided with a cleaning interface, and can be cleaned at one time under high pressure within half a minute.

The ultra-micro colloid mill has the advantages of low cost, long service life, low temperature, high fineness, low speed, low voltage, environmental protection and energy saving. The machine material is food-grade and has wide application range. Is an upgrade version of the common colloid mill, is a new product for replacing the future development of the common colloid mill, and is also a substitute of the common stone mill, the grinding wheel mill, the ball mill, the emulsion homogenizing machine, the three-roller machine and the stamping machine. Meanwhile, the wet grinding technology is a latest development technology and has wide development prospect. And can be used in large national major engineering. Can also help more needed companies, enterprises, individuals and all needed field industries to solve various corresponding difficult problems of grinding.

The above examples are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above examples, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and scope of the present invention are equivalent substitutions and are included in the protection scope of the present invention.

Claims

1. A colloid mill funnel, its characterized in that: comprises a funnel body, a funnel rotating piece and a water inlet; the lower end of the funnel body is provided with a discharge hole, the inner wall of the funnel body is provided with a guide vane extending towards the discharge hole of the funnel body, the guide vane is a spiral guide vane, and the guide vane extends from the upper end of the inner wall of the funnel body towards the discharge hole of the funnel body along a spiral shape; the water inlet is arranged at the upper end of the side wall of the funnel body; the funnel rotating piece is a triangular rotating piece and is arranged in the funnel body, the funnel rotating piece can rotate through an external power source, the rotation axis of the funnel rotating piece coincides with the central axis of the funnel body, the funnel rotating piece is connected with a screw, and a spiral pushing piece is arranged at the discharge hole of the funnel around the lower surface of the screw;

the colloid mill funnel utilizes a self-rotating funnel rotating sheet to drive a material to rotate in a vortex manner in the funnel, and meanwhile, the spiral guide sheet enables the material to keep a certain track to perform vortex sliding and generate a centrifugal force to the periphery, so that larger-particle materials, heavier materials and solid materials in a material mixture to be ground, which are added into the funnel, are preferentially transferred to the bottom under the action of the rotating centrifugal force and the action of the spiral guide sheet, and then preferentially enter a grinding disc area to be ground, and the function of preferentially grinding after classification is achieved;

the ground material and the water material enter the funnel, and under the action of inertia and the spiral guide vane on the inner wall of the funnel, the material is accelerated to be screwed into the primary grinder for grinding under the action of the inertia and the spiral guide vane on the inner wall of the funnel, so that the material is prevented from entering a grinding area effectively in time after being put into the funnel.

2. A colloid mill funnel as claimed in claim 1, wherein: still include the protective cover, the protective cover sets up the top surface of funnel body.

3. A colloid mill funnel as claimed in claim 2, wherein: the protective cover is a V-shaped protective cover.

4. A colloid mill funnel as claimed in claim 1, wherein: the width of the funnel rotating piece gradually decreases from top to bottom.

5. A colloid mill funnel as claimed in claim 1, wherein: and a strong magnetic filter is arranged at the discharge hole of the funnel body.

6. A colloid mill funnel as claimed in claim 1, wherein: the lower end of the side wall of the funnel body is provided with a lapping flow inlet for material backflow.
