Ball mill rubber lifting strip mounting structure

Technical Field

The invention relates to the technical field of ball mill accessories, in particular to a rubber lifting strip mounting structure of a ball mill.

Background

A lifting bar on the traditional ball mill adopts a steel skeleton, so that the manufacturing process is complex, the forming is difficult, and the size error is large. Meanwhile, the T-shaped bolt is generally adopted to fix the lifting strip, the forging quality of the T-shaped bolt is unstable, the T-shaped bolt is greatly influenced by the technology and the production level of a supplier, the bolt is easy to break in the field use process, equipment is temporarily stopped to replace the bolt, and loss is caused to a concentrating mill.

Disclosure of Invention

The invention aims to provide a mounting structure for a rubber lifting strip of a ball mill, which has the characteristics of convenience in mounting and stable structure.

The technical scheme adopted by the invention is as follows: ball mill rubber lifting strip mounting structure, including the mill barrel, fix the welt on this mill barrel, fix the lifting strip that the rubber material on this welt prepared, the inside skeleton section bar that is equipped with the aluminum alloy material preparation of lifting strip, the section of skeleton section bar is "pi" shape to have opening "T" type groove down, simultaneously, "T" type inslot card has the section to be the cushion of "T" font, penetrating perforation about the cushion middle part is equipped with, fenestrate upper portion is regular hexagon, wear to be equipped with hexagonal screw down in the perforation from last, hexagonal screw is furnished with hexagon nut, and, after passing welt and mill barrel from last to down in proper order, compress tightly on the lower surface of this mill barrel after hexagon nut screws.

The liner plate is provided with embedded grooves, and the lower parts of the lifting strips are embedded in the corresponding embedded grooves.

Inclined planes are arranged on two sides of the upper portion of the cushion block.

The framework section is formed by extruding 6061 aluminum alloy, and the lifting strips are bonded and formed with the corresponding framework through rubber heat vulcanization.

Compared with the prior art, the invention has the advantages that: the installation is comparatively convenient, the structure is comparatively stable. The ball mill rubber lifting strip mounting structure provided by the invention adopts the section bar made of the aluminum alloy material as the framework, and the aluminum alloy framework and the rubber are bonded and formed through a rubber hot vulcanization process, so that the combination is tight, and the ball mill rubber lifting strip mounting structure is easy to prepare and form. Meanwhile, the cross section of the framework section is in a shape like the Chinese character 'pi', the two sides of the cross section are provided with the side wings, so that the combination of the framework section and the rubber lifting strip is more reasonable and stable, the T-shaped groove is formed in the cross section, the cushion block is easy to penetrate, the installation of the bolt is facilitated, the bolt can be a standard part, the cost is lower, the special forging is not needed, and the installation is more convenient and stable.

Detailed Description

Examples, see fig. 1-3: the installation structure of the rubber lifting strip of the ball mill comprises a mill cylinder body 10, a lining plate 20 fixed on the mill cylinder body 10 and a lifting strip 30 made of rubber materials and fixed on the lining plate 20.

Further speaking:

the inside of the lifting bar 30 is provided with a framework section bar 40 made of an aluminum alloy material. The section of the frame profile 40 is "pi" shaped and thus has a "T" shaped groove 41 with a downward opening. That is, the upper both sides of the frame profile 40 are provided with the wings 411 extending outward. Meanwhile, a cushion block 50 with a T-shaped section is clamped in the T-shaped groove 41. The spacer 50 is preferably formed by precision casting, and is made of cast steel ZG-310, thereby having high structural strength, precise size and low cost. The spacer 50 can slide in from one end of the "T" shaped slot 41 but will not fall out. The middle part of the cushion block 50 is provided with a through hole 51 which is through up and down, the upper part of the through hole 51 is in a regular hexagon shape, and the lower part is in a round shape. A hexagonal screw 60 is inserted into the through hole 51 from top to bottom. That is, the upper portion of the hexagonal screw 60 is just caught in the upper regular hexagonal portion of the corresponding through hole 51. The hexagonal screw 60 is provided with a hexagonal nut 61. And after the hexagonal screw rod 60 sequentially passes through the lining plate 20 and the mill cylinder 10 from top to bottom, the hexagonal nut 61 is tightly screwed and then is tightly pressed on the lower surface of the mill cylinder 10. Of course, the lining plate 20 and the mill cylinder 10 are provided with through holes through which the hexagonal screws 60 pass. Therefore, the compactness and stability of the whole structure are ensured, and the assembly is convenient.

Optimizing:

the lining plate 20 is provided with an embedded groove 21, and the lower part of the lifting strip 30 is embedded in the corresponding embedded groove 21. I.e. to ensure relative stability between the lifting bar 30 and the liner 20.

The upper portion of the spacer 50 is provided with inclined surfaces 52 at both sides thereof, and the inclined surfaces 52 are along the extension direction of the T-shaped groove 41, so as to guide the spacer 50 into the T-shaped groove 41.

The frame section 40 is formed by extruding 6061 aluminum alloy, and the lifting strip 30 is bonded and formed with the corresponding frame 40 through rubber heat vulcanization. In this way, the combination between the parts is more stable, and the framework section bar 40 has higher strength.

In addition:

the lower part of the hexagonal screw 60 can also be sleeved with a bowl-shaped sealing ring 72 and a bowl-shaped gasket 71 which are positioned below the mill barrel 10 and above the hexagonal nut 61, and the bowl-shaped sealing ring 72 and the bowl-shaped gasket 71 are distributed up and down so as to enable the structure to be more stable.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
