Description
Technical Field
The utility model belongs to the technical field of large-scale ball mill equipment, and particularly relates to a wear-resistant impact-resistant ball mill feeding elbow.
Background
After the ball mill is subjected to large-scale transformation, the machine hour is greatly improved, the requirements on the structure and the service life of the ore feeding bent pipe at the inlet of the ball mill are higher, and the ore feeding bent pipe is directly adopted for ore feeding of the ball mill. The ore feeding elbow of the ball mill is a component for feeding raw ore and steel balls into the ball mill, the structure of the ore feeding elbow of the raw ball mill is divided into an upper part and a lower part, the upper part is a square inclined hopper body 1, the lower part is a U-shaped groove body 2, an ore feeding pipe 3 of the ball mill is inserted into the rear part of the U-shaped groove body 2, the front end of the ore feeding pipe of the ball mill is a reducing throat, the U-shaped groove body 2 is horizontally inserted into the ball mill, and a common reducing part and the U-shaped groove form an included angle of 135 degrees as shown in figures 1 and 2. The working principle is that raw ore and steel balls are fed from the upper part in the ore feeding bent pipe and are converged into the lower U-shaped groove body, and the raw ore and the steel balls are fed into the ball mill through the ore feeding pipe of the ball mill due to the combined action of the inertia of settled sand ore pulp fed from the rear part and impact ore pulp, wherein the U-shaped groove body is inclined with the horizontal direction. The main problems that exist are:
1. the corresponding position of the ball mill feeding elbow pipe for discharging ore from the U-shaped groove has poor impact resistance, the newly replaced feeding elbow pipe is smashed and leaked in less than 30 days on average, the leakage starts in 18 days at the fastest speed, the failure rate is high, the service life is short, and the impact on production is great after 8 months per station on average.
2. The spare parts consumption is large, and the production cost is high.
3. The maintenance method passively adopts external repair welding for reinforcement, the effect is poor, and the repair frequency is high.
4. The equipment operation efficiency is reduced, the repair welding maintenance cost is repeatedly maintained, and the labor cost is increased.
Disclosure of Invention
The utility model aims to provide a wear-resistant impact-resistant ball mill feeding elbow pipe which is long in service life and convenient to maintain.
The purpose of the utility model is realized by the following technical scheme:
the utility model discloses a wear-resistant impact-resistant ball mill feeding elbow, which comprises a feeding elbow consisting of a square inclined hopper body at the upper part and a U-shaped groove body at the lower part, and a feeding pipe arranged at one end of the U-shaped groove body.
Preferably, square inspection and maintenance holes are formed in the upper portion of the rib plate and at two ends of the U-shaped groove body, and flanges and cover plates are arranged on the square inspection and maintenance holes.
Preferably, the bottom of the rib plate is of an arc structure matched with the bottom of the U-shaped groove body, the length direction of the rib plate is axially parallel to the ore feeding bent pipe, the bottom of the rib plate is in fit welding with the bottom of the U-shaped groove body, and the front end of the rib plate is at an included angle of 45 degrees.
Preferably, the distance between the rib plates is 80-90 mm.
Preferably, the wear-resistant material is a champion 218 wear-resistant material.
The utility model has the advantages that:
because each rib plate and the filled wear-resistant material cover the whole easily-worn area, the utility model can effectively resist the impact force of ores and steel balls, and has stronger wear resistance and longer service life. The square inspection and maintenance hole is convenient to inspect and maintain, and the maintenance cost and the maintenance time can be reduced.

Detailed Description
The present invention will be further described with reference to the following examples.
As shown in figures 1-2, the wear-resistant impact-resistant ball mill feeding elbow comprises an ore feeding elbow composed of a square inclined bucket body 1 at the upper part and a U-shaped groove body 2 at the lower part, and an ore feeding pipe 3 arranged at one end of the U-shaped groove body, and is characterized in that rib plates 5 are arranged on the inner wall of an easily-worn area of a discharge port of the U-shaped groove body 2 at intervals, and wear-resistant materials 6 are filled at the intervals of the rib plates 5 to cover the whole easily-worn area. The bottom of a rib plate 5 is of an arc structure matched with the bottom of a U-shaped groove body, the length direction of the rib plate 5 is axially parallel to an ore feeding bent pipe 2, the bottom of the rib plate 2 is in fit welding with the bottom of the U-shaped groove body, and the front end of the rib plate has an included angle of 45 degrees; the space between the rib plates is 80-90 mm; the wear-resistant material is a Cuexin 218 wear-resistant material, can effectively resist the impact force of ores and steel balls, and has strong wear resistance and long service life.
The utility model is arranged on the upper part of a rib plate, two ends of a U-shaped groove body 2 are provided with square inspection and maintenance holes 4, and the square inspection and maintenance holes 4 are provided with flanges 7 and cover plates. The inspection and the maintenance are convenient, and the maintenance cost and the maintenance time can be reduced.
