The limitation of the layout is inconvenient to install, and the investment is relatively large, so it is difficult to promote on a large scale.

Contents of the invention

The purpose of the utility model is to provide an automatic rotary ball removing machine which relies on the pressure of the material discharged from the ball mill to provide power for the work of removing the crushed balls.

An automatic rotary ball removing machine, comprising a frame body and a sieve cylinder arranged on the frame body, a support device is arranged between the frame body and the sieve cylinder, and the sieve cylinder can move relative to the support device, one end of the sieve cylinder It is the feed inlet, and the other end is the crushed ball discharge end. The inner cavity of the screen drum is equipped with rotating blades near the feed port, and the rotating blades are fixed on the inner wall of the screen drum. , there is a receiving trough under the screen drum;

The rotating blade is composed of a plurality of individual blades and the blades are arranged around the inner wall of the screen drum, the outer circumference of the rotating blade is fixed on the inner wall of the screen drum by bolts and the blades can rotate around the bolt as the axis;

The support device includes a feeding pipe fixed on the frame and supporting rollers, the feeding port of the screen drum is connected to the feeding pipe through a bearing, and the broken ball discharge end of the screen drum is arranged on the supporting rollers;

The broken ball conveying positive screw extends from the rotating blade to the broken ball discharge end of the screen cylinder;

The frame body is provided with a casing and the casing wraps the sieve drum therein;

A broken ball collecting tank is arranged below the broken ball discharge end of the screen cylinder.

The utility model has the following beneficial effects:

1. The utility model uses the residual pressure produced by the discharge of the ball mill to impact the rotating blades in the screen, and drives the screen cylinder to rotate without using other power sources to achieve the purpose of energy saving; the screen of the screen cylinder filters the broken balls and removes them The rotation of the crushing ball screw will discharge the crushing balls, so as to complete the separation of the material of the coal mill from the crushing balls;

2. The angle of the rotating blade can be adjusted. By adjusting the angle of the rotating blade, the rotating speed of the cylindrical screen can meet the needs of the separation work;

3. The utility model has the advantages of small footprint, simple structure, and convenient installation and maintenance.

Detailed ways

As shown in Figures 1 to 3, an automatic rotary ball removing machine includes a frame body 1, a screen cylinder 2 arranged on the frame body 1, a support device is arranged between the frame body 1 and the screen cylinder 2, and The screen cylinder 2 can move relative to the support device, which includes the feed pipe 3 and the support roller 4 fixed on the frame body. One end of the screen cylinder 2 is the feed port, and the other end is the crushed ball discharge end. The feeding port of 2 is connected to the feeding pipe 3 through the bearing 5, and the crushed ball discharge end of the sieve cylinder 2 is set on the support roller 4; the inner cavity of the sieve drum 2 is provided with a rotating blade 6 near the feeding port, and the rotating blade 6 is composed of a plurality of individual blades and the blades are arranged around the inner wall of the screen drum 2, the outer circumference of the rotating blade 6 is fixed on the inner wall of the screen drum 2 by bolts and the blades can rotate around the bolt as the axis; the inner wall of the screen drum 2 A crushed ball conveying positive screw 7 is provided, and the crushed ball conveying positive spiral 7 extends from the rotating blade 6 to the crushed ball discharge end of the screen cylinder 2; A broken ball collection tank 10 is arranged below the broken ball discharge end, and a casing 9 is arranged on the frame body 1 and the casing 9 wraps the sieve cylinder 2 therein.

When working, the discharge end of the ball mill is connected to the feed pipe 3, and the materials and crushed balls in the ball mill enter the sieve cylinder 2 through the feed pipe 3, and the materials push the rotating blade 6 to drive the sieve cylinder 2 to rotate and pass through the screen of the sieve cylinder 2 Leave the sieve cylinder 2 and enter the material receiving trough 8 under the action of gravity, the broken balls are intercepted by the screen in the sieve cylinder 2, when the sieve cylinder 2 rotates, it drives the positive screw 7 for removing the broken balls to rotate the broken balls in the sieve cylinder 2 from the crushed The ball discharge end is discharged into the crushed ball collection tank 10, so as to achieve the purpose of separating the crushed balls from the material; the rotation speed of the screen cylinder 2 is changed by adjusting the angle of the rotating blade 6; during the rotation of the screen cylinder 2, part of the material is thrown out due to centrifugal action The screen cylinder 2 intercepts the material through the shell 9 and finally flows into the receiving tank 8 .
