After ball mill carries out maximization transformation, amount has large increase during platform, to giving ore deposit bent portion at ball mill inlet
Bit architecture and life-span and seal request are higher, and ball mill mineral-feeding directly uses and gives ore deposit elbow, general using Φ 428 × 1350
The elbow of logical steel either cast iron quality, in use due to the impact washed away with steel ball of ore pulp, 14 days or so curved
Head occurs as soon as leak source, it is necessary to changed, often change an elbow, ball mill need to stop 6 hours, monthly need to change it is secondary,
It is very big to Influence of production.The problem of existing, one is due to too high using the bend pipe manufacturing cost of cast iron or alloy cast steel material, is made
Low with rate, two be due to that elbow directly contacts ore pulp, and serious abrasion can be produced to inwall, causes the reduction of bend pipe service life,
Have a strong impact on ball mill operation effectiveness.
The content of the invention
The utility model is in order to solve the above-mentioned technical problem, there is provided a kind of special feed bend pipe of ball mill, its design structure
Simply, it is scientific and reasonable, it is easy to use；The feed bend pipe of original cast iron or cast steel is changed to inside and outside solder type bend pipe, and thickeied
Bend pipe lower inner wall, the size that interior upper wall is thinned, to improve the wearability of bend pipe, increase the service life.
Technical scheme is used by the utility model：A kind of special feed bend pipe of ball mill, including mounting seat and body,
Body is hollow structure, and body is arc, and body one end is connected with charging flange, and body other end is connected with discharging flange,
The carbon steel pipe of body including outer layer and the wear-resistant pipe of internal layer, carbon steel pipe are fixedly connected with wear-resistant pipe, wear-resistant pipe include lower inner wall with
Interior upper wall, lower inner wall are in contact with mineral aggregate, and the wall thickness of lower inner wall is more than the wall thickness of interior upper wall, and installation is provided with the outside of carbon steel pipe
Seat, mounting seat are provided with gusset with carbon steel pipe junction.
The carbon steel pipe is A3 steel, and wear-resistant pipe is rich chromium cast iron material.
The charging flange welding is in body one end, and discharging flange welding is in body other end.
The gusset is fixedly connected with mounting seat, and gusset is fixedly connected with carbon steel pipe.
The use process of the special feed bend pipe of this ball mill is：The bend pipe is fixed using mounting seat, feeds method
The tremie pipe of orchid connection equipment, discharging flange connection feed pipe, mineral aggregate enter inside bend pipe from flange is fed, led from discharging flange
Go out, because wall thickness of the wear-resistant pipe close to gusset side is more than the wall thickness away from gusset side, can be reduced during feeding
The damaged probability of bend pipe work inwall, wear-resistant pipe is rich chromium cast iron material, extends the service life of bend pipe, reduces the frequency of maintenance
Rate, it is cost-effective.
The body includes the carbon steel pipe of outer layer and the wear-resistant pipe of internal layer, and mounting seat, mounting seat are provided with the outside of carbon steel pipe
Carbon steel pipe junction is provided with gusset；The purpose so set is：Bend pipe can be improved during mineral aggregate is conveyed
Stability, improve bend pipe to the impact resistance in mineral aggregate course of conveying, ensure the smoothness of feeding.
The wear-resistant pipe includes lower inner wall and interior upper wall, lower inner wall are in contact with mineral aggregate, and the wall thickness of lower inner wall is more than on interior
The wall thickness of wall；The purpose so set is：The wearability of elbow internal wall working face can be increased, be advantageous to improve the use of elbow
In the life-span, reduce the frequency for changing bend pipe.
The beneficial effects of the utility model：The technical program provides a kind of special feed bend pipe of ball mill, its design structure
Simply, it is scientific and reasonable, it is easy to use；The wearability of ball mill feed bend pipe can be improved, mineral aggregate is reduced and bend pipe is caused to wear
Probability, improve the service life of bend pipe, also reduce the frequency that bend pipe is changed, reduce production cost.
