Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a feeding device for a ball mill. Background Art

[0002] Ball mill is the key equipment for crushing materials after they are broken. This type of mill is a mill that is loaded with a certain number of steel balls as grinding media in its cylinder. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics and other production industries. It can grind various ores and other grindable materials in dry or wet manner. Ball mill is suitable for grinding various ores and other materials. The feeding device can quickly guide the material into the ball mill.

[0003] During the feeding process of the existing ball mill feeding device, the feeding pipe is blocked due to the inconsistency of the size of the crushed materials, and a large amount of dust is generated during the feeding, which affects the working environment.

[0004] Therefore, a feeding device for a ball mill is proposed. Utility Model Content

[0005] In view of this, the embodiments of the present utility model hope to provide a feeding device for a ball mill to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0006] The technical solution of the utility model embodiment is achieved as follows:

[0007] A feeding device for a ball mill comprises a main body mechanism and a dust reduction mechanism arranged at the bottom of the main body mechanism, the main body mechanism comprising: a material storage box, a mounting rod arranged inside the material storage box, a limit block arranged at the bottom of the mounting rod, a servo motor arranged at the bottom of the material storage box, a rotating block arranged at the output end of the servo motor, and a rotating plate arranged around the rotating block; the dust reduction mechanism comprises a discharge pipe arranged at the bottom of the material storage box, a dust removal box arranged at one end of the discharge pipe, a dust suction pump arranged at the top of the dust removal box, a dust collecting box arranged at one side of the dust suction pump, a cover plate arranged at the top of the dust collecting box, and a dustproof net arranged inside the cover plate.

[0008] In some embodiments, a hose is provided on one side of the dust removal box, and a material guide trough is provided inside the hose.

[0009] In some embodiments, a discharge hopper is provided at one end of the hose, and a discharge port is provided inside the discharge hopper.

[0010] In some embodiments, a sealing ring is provided at the bottom of the cover plate, and a dust removal chamber is provided inside the dust removal box.

[0011] In some embodiments, a material storage trough is disposed inside the material storage box, a top plate is disposed on the top of the material storage box, and a clamping ring is disposed on the bottom of the top plate.

[0013] In some embodiments, a feed hopper is disposed on the top of the top plate, and a feed port is disposed inside the feed hopper.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] 1. The utility model is a feeding device for a ball mill. When feeding, after the crushed raw materials enter the storage box, the limit block at the bottom of the mounting rod inside the storage box blocks the larger crushed pieces to prevent blockage caused by the larger materials during feeding, and the servo motor drives the rotating plates around the rotating block to move the materials at the bottom of the storage box, further improving the anti-blocking performance.

[0016] 2. The utility model provides a feeding device for a ball mill. When the material is in use, after the material enters the dust removal box through the discharge pipe, the dust suction pump on the top of the dust removal box sucks the dust inside the dust removal box and introduces it into the dust collecting box. The air passes through the dustproof net on the top of the cover plate and is discharged to the outside. The dust generated during feeding is collected to reduce pollution to the working environment.

A servo motor 104 bolted to the bottom of the material storage box 101, a rotating block 105 welded to the output end of the servo motor 104, and a rotating plate 106 bolted to the periphery of the rotating block 105. The servo motor 104 drives the rotating plate 106 to rotate around the rotating block 105. The movable plate 106 moves the material at the bottom of the storage box 101; the dust reduction mechanism 200 includes a discharge pipe 201 bolted to the bottom of the storage box 101, a dust removal box 202 bolted to one end of the discharge pipe 201, a dust suction pump 203 bolted to the top of the dust removal box 202, and a dust collecting box 204 bolted to one side of the dust suction pump 203, a cover plate 205 snap-fitted to the top of the dust collecting box 204, and a dustproof net 206 snap-fitted to the inside of the cover plate 205. After the material enters the dust removal box 202 through the discharge pipe 201, the dust suction pump 203 on the top of the dust removal box 202 sucks the dust inside the dust removal box 202 and introduces it into the dust collecting box 204, and the air passes through the dustproof net 206 on the top of the cover plate 205 and is discharged to the outside.
