Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a ball mill erodees subassembly. Referring to fig. 1 and 2, a ball mill scouring assembly includes a discharge tube 2 integrally connected with a ball mill 1. The one end that discharging pipe 2 kept away from ball mill 1 can be dismantled and be connected with screen cloth 3, and discharging pipe 2 inclines towards the one end that is close to screen cloth 3 by the one end that is close to ball mill 1, and the cross-section of discharging pipe 2 near the one end of ball mill 1 is greater than the cross-section of discharging pipe 2 near the one end of screen cloth 3. In the present embodiment, the screen mesh 3 is a circular truncated cone screen. One end that the 2 inside walls of discharging pipe are close to screen cloth 3 is fixed with water pipe 4, and the one end that 2 inside walls of discharging pipe were kept away from to water pipe 4 inclines towards screen cloth 3.

Through the setting of water pipe 4, because the impulsive force of water for the coarse grain that is stifled on the sieve mesh drops easily, makes the sieve mesh be difficult to be plugged up, makes the material discharge from the sieve mesh easily, is favorable to improving ball mill 1's discharging efficiency.

Referring to fig. 3, a convex ring 31 is protruded from the edge of the screen 3 near one end of the tapping pipe 2, the convex ring 31 is annular, the outer diameter of the convex ring 31 is equal to the outer diameter of the tapping pipe 2, and the inner diameter of the convex ring 31 is equal to the inner diameter of the tapping pipe 2. The protruding ring 31 is provided with two circular holes 33, and in this embodiment, the two circular holes 33 are symmetrically arranged on the protruding ring 31. One end of the discharge pipe 2, which is far away from the ball mill 1, is recessed with a threaded hole 34, and the threaded hole 34 is in threaded connection with a bolt 32. When the male ring 31 abuts against the end of the discharge pipe 2 remote from the ball mill 1, the screw hole 34 faces the circular hole 33, and the bolt 32 is screwed into the screw hole 34 through the circular hole 33.

Can dismantle with the inside wall of discharging pipe 2 through screen cloth 3 and be connected, be favorable to screen cloth 3's dismantlement for screen cloth 3's change is more convenient.

Referring to FIG. 3, the side of the screen 3 is inclined from the end close to the inner side wall of the tapping pipe 2 to the end far from the inner side wall of the tapping pipe 2, and the cross section of the end of the screen 3 close to the inner side wall of the tapping pipe 2 is larger than the cross section of the end of the screen 3 far from the inner side wall of the tapping pipe 2.

Through the oblique setting in 3 sides of screen cloth, be favorable to the coarse grain that the sieve was come out can not get back to ball mill 1 through the screen cloth 3 better and continue to grind, be favorable to improving the discharging efficiency of material.

Referring to fig. 3, a ring groove 21 is recessed in one end, close to the screen mesh 3, of the inner side wall of the discharge pipe 2, a circular pipe 22 is fixed in the ring groove 21, the circular pipe 22 is arranged around the ring groove 21, and the water pipe 4 is fixed on the circular pipe 22 and is communicated with the circular pipe 22. In the present exemplary embodiment, four water pipes 4 are provided, four water pipes 4 being distributed uniformly in the circumferential direction of the tapping pipe 2.

Through 4 evenly distributed of four water pipes for water pipe 4 evenly erodees towards screen cloth 3 better, makes the coarse grain that is difficult to appear on the sieve mesh erode the condition that can not, makes screen cloth 3 be difficult to be blockked up, is favorable to the material to discharge from the sieve mesh.

Referring to FIG. 3, the diameter of the water pipe 4 decreases from the end close to the inner side wall of the tapping pipe 2 to the end remote from the inner side wall of the tapping pipe 2.

Through the setting to 4 diameters of water pipe for the pressure increase of the one end of 2 inside walls of discharging pipe is kept away from to water at water pipe 4 is favorable to increasing the impact force of water to screen cloth 3, makes the coarse grain on the sieve mesh drop out, is favorable to the discharge of material.

Referring to fig. 3, a pipe 41 communicating with the circular pipe 22 is inserted through the outer side wall of the discharge pipe 2, and a ball valve 42 for adjusting water flow is fixed to the pipe 41.

The implementation principle of the scouring assembly of the ball mill in the embodiment of the application is as follows: when the coarse particle in the material blocks up and can not drop in the sieve mesh, at first open the switch of ball valve 42 for water flows to water pipe 4 through pipeline 41, then water rushes out and erodees towards screen cloth 3 from water pipe 4, will be stopped up the coarse particle on the sieve mesh at last and dash and fall down, makes screen cloth 3 be difficult to be blockked up, makes the material flow out from screen cloth 3 more easily, accomplishes the washing out to screen cloth 3 promptly.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
