Description

Technical Field

[0001] This utility model relates to the field of ball mill component technology, and in particular to a dust cover for a ball mill. Background Technology

[0002] Ball mills are key equipment for material grinding and are widely used in industries such as cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal ore beneficiation, and glass and ceramics.

[0003] Existing ball mills have the following drawbacks during use: When using a ball mill, the ground material needs to be discharged. During the discharge process, especially when discharging powder, the powder is easily scattered, which can pollute the workshop environment and lead to unnecessary waste. To address this, we propose a dust cover for ball mills. Utility Model Content

[0004] The main purpose of this utility model is to provide a dust cover for a ball mill. By adding a dust reduction mechanism to the end of the ball mill body, the phenomenon of powder floating out during the discharge process of the ball mill can be effectively reduced, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dust cover for a ball mill includes a ball mill body and a dust suppression mechanism. The dust suppression mechanism is provided at the discharge end of the ball mill body. The dust suppression mechanism includes a base, a bushing, a dust cover, a propeller blade, a transverse groove, a screw groove, a screw sleeve, a fixing rod, an arc-shaped rubber pad, an end cap, and a discharge pipe. A bushing is provided on the top of the base, and a dust cover that mates with the discharge end of the ball mill body is installed horizontally inside the bushing. A propeller blade is welded to the inner wall of the dust cover. A transverse groove is opened horizontally at the connecting end of the dust cover, and a screw groove is opened on the outer wall of the dust cover near the transverse groove. A screw sleeve is screwed into the dust cover through the screw groove, and a fixing rod is fixedly connected to both sides of the outer wall of the screw sleeve. An arc-shaped rubber pad is adhered to the inner wall of the dust cover near the discharge end of the ball mill body. An end cap is provided at the top of the base away from the ball mill body, and a discharge pipe is installed at the end of the end cap away from the dust cover.

[0007] Furthermore, it also includes a cleaning mechanism. The cleaning mechanism is provided on the top of the base. The cleaning mechanism includes a fan, an exhaust pipe, a guide ring, and an exhaust hole. The fan is installed on the top of the base, and an exhaust pipe is installed on the exhaust end of the fan. A guide ring is installed inside the dust cover near the main body of the ball mill. An exhaust hole is opened on the surface of the guide ring facing the discharge pipe. A guide ring structure is provided inside the dust cover near the powder inlet. Under normal discharge conditions, the powder passes through the inside of the guide ring under the conveying action of the propeller blades and is discharged from the discharge pipe. After the ball mill discharge is completed, the fan is turned on. The air force generated by the fan blows into the inside of the guide ring through the exhaust pipe and then out through the exhaust hole, which can sweep the inside of the dust cover and blow away and discharge the powder that adheres to the inner wall of the dust cover during the discharge process.

[0008] Furthermore, a groove is provided at the end of the arc-shaped rubber pad on one side of the inner wall of the dust cover, and a protrusion is integrally formed at the end of the arc-shaped rubber pad on the other side of the inner wall of the dust cover; when the ends of the dust cover are aligned, the protrusion is inserted into the groove, thereby making the arc-shaped rubber pad completely fit the outer periphery of the discharge end of the ball mill body.

[0009] Furthermore, a support rod is fixedly connected to the top of the base and connected to the end cover through the support rod. The end of the dust cover is provided with a tube that is inserted into the end cover. The support rod supports the end cover, and the tube at the end of the dust cover rotates inside the end cover, so that the powder inside can be normally discharged into the discharge tube.

[0010] Furthermore, the bottom of the guide ring is fixedly connected to an air inlet pipe extending to the outside of the dust cover, and the air inlet pipe is connected to the end of the exhaust pipe; when it is necessary to clean the inside of the dust cover, simply connect the exhaust pipe to the air inlet pipe.

[0011] Compared with the prior art, this utility model has the following beneficial effects: The ball mill body performs material crushing and grinding. When the grinding of the material is completed and discharge is required, the base is moved to a position close to the discharge end of the ball mill body. At this time, the screw sleeve is away from the transverse groove, and the opening of the dust cover connection end is large enough to be fitted onto the outer circumference of the ball mill's discharge pipe. After being fitted into place, the screw sleeve is screwed towards one side of the transverse groove, using the screw sleeve to clamp the dust cover connection end, so that the arc-shaped rubber pad completely fits the discharge pipe. At the same time, the dust cover is connected and fixed to the discharge end of the ball mill body. At this time, the ball mill rotates to discharge material, and the dust cover is driven to rotate synchronously inside the bushing. The powder enters the dust cover... The dust is conveyed by the propeller blades inside the dust hood and finally discharged into the material-using equipment through the discharge pipe, reducing dust dispersion during the ball mill discharge process, protecting the workshop environment, and reducing unnecessary waste. A guide ring structure is provided inside the dust hood near the powder inlet. Under normal discharge conditions, the powder passes through the guide ring under the conveying action of the propeller blades and is discharged from the discharge pipe. After the ball mill discharge is completed, the fan is turned on. The air force generated by the fan blows into the guide ring through the exhaust pipe and then out through the exhaust hole, which can sweep the inside of the dust hood and blow away the powder that adheres to the inner wall of the dust hood during the discharge process.
