Description

Lining plate of semi-autogenous mill

Technical Field

The utility model relates to a semi-autogenous mill especially indicates a semi-autogenous mill welt.

Background

In the fields of mines, electric power and the like in China, the material grinding technology is continuously improved and developed, and in order to ensure the grinding efficiency of materials, a large-scale autogenous mill is widely applied. The autogenous mill has been adopted by more and more mines at home and abroad due to simple flow, convenient configuration and small investment.

The discharge end of the semi-autogenous mill is usually provided with a lining plate and rubber packing, however, due to the structural defects, the existing rubber packing is exposed outside, the service life is short due to large abrasion, and the rubber packing needs to be frequently replaced. Meanwhile, the hoisting plates of the existing lining plate are arranged on the left side and the right side of the middle boss, so that the movement of materials and balls can be hindered when grinding materials are used, and the grinding efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a semi-autogenous mill welt has solved the problem that the hoist and mount board of current welt influences material and ball motion.

The technical scheme of the utility model is realized like this: the utility model provides a semi-autogenous mill welt, includes welt bottom plate and middle boss, and the both ends of middle boss are equipped with the pedestal, are equipped with the otic placode on the pedestal, and the otic placode is connected with the splint of U-shaped, and the earhole on the otic placode corresponds with the connecting hole on the splint, is equipped with bolt spare in earhole and the connecting hole, and the otic placode of one side is connected with the baffle.

The connecting included angle between the lining plate bottom plate and the middle boss is in arc transition.

And mounting holes are formed in two ends of the middle boss.

The middle boss is an isosceles trapezoid cross section.

The middle lug boss is integrally connected with the lug plate.

The ear plate is provided with two ear holes.

The cross section of the middle boss corresponds to that of the clamping plate.

The two sides of the middle boss are provided with cylindrical bulges.

The utility model has the advantages that: the hoisting plate of the left side and the right side is cancelled, and the lug plate is arranged at the front end and the rear end, so that the grinding efficiency is ensured without influencing the movement of materials and balls, meanwhile, the clamping plate and the lug plate are combined into the middle boss, the integrity of the whole structure is ensured, and the clamping plate connecting baffle on one side protects the rubber packing, so that the service life of the rubber packing is prolonged.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a front view of the present invention.

Fig. 2 is a top view of the present invention.

Fig. 3 is a view from a-a of fig. 1.

In the figure: 1-lining plate bottom plate, 2-middle boss, 3-mounting hole, 4-pedestal, 5-lug plate, 6-lug hole, 7-clamping plate, 8-baffle plate, 9-connecting hole and 10-bolt piece.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in figures 1-3, the lining plate of the semi-autogenous mill comprises a lining plate bottom plate 1, a middle boss 2, a mounting hole 3, a pedestal 4, an ear plate 5, an ear hole 6, a clamping plate 7, a baffle plate 8, a connecting hole 9 and a bolt piece 10.

The lining plate bottom plate 1 and the middle boss 2 are integrally manufactured, the middle boss is located in the middle position above the lining plate bottom plate, and the middle boss 2 is of an isosceles trapezoid cross section. The connecting included angle between the lining plate bottom plate 1 and the middle boss 2 is in arc transition. Mounting holes 3 are formed in two ends of the middle boss 2 and used for mounting the lining plate at the discharge end of the semi-autogenous mill.

The both ends of middle boss 2 are equipped with pedestal 4, are equipped with a body coupling's otic placode 5 on pedestal 4, and otic placode 5 is connected with the splint 7 of U-shaped, and the earhole 6 on the otic placode 5 corresponds with connecting hole 9 on the splint 7, is equipped with two earholes 6 on every otic placode 5, and is the same, also is equipped with two connecting holes on every splint, guarantees splint stable connection on the otic placode, avoids splint activity. The lug holes 6 and the connecting holes 9 are internally provided with bolt pieces 10, and the splint and the lug plate are connected together through the bolt pieces.

The otic placode that both ends set up around has replaced the otic placode of traditional left and right sides, both can hoist and mount and transport, has also avoided the otic placode of the left and right sides to influence the problem of material and ball motion. After the hoisting is completed, the clamping plate can be installed on the lug plate, and the cross section of the middle boss 2 is the same as that of the clamping plate 7, so that the lug plate and the clamping plate form a boss structure with the same section as that of the middle boss, and the lug plate and the clamping plate can still be used as a boss.

Wherein the otic placode 5 and the baffle 8 of one side are connected, and the baffle is protected rubber packing and is sheltered from, avoids rubber packing to expose and receive unnecessary wearing and tearing outside to improve rubber packing's life. The both sides of middle boss 2 are equipped with the cylinder arch, and the cylinder arch is used for protecting the welt, reduces the impact force and the grinding effect of material and ball to the welt.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
