Abstract
The utility model discloses a kind of novel feed elephant trunk, including feed chute and replaceable buildup slot, the feed chute is equipped with square aperture in bottom, extends outward along square aperture, is equipped with square flange in the end of extension；The replaceable buildup slot is square tubular, is equipped with square opening flange in the end of square tube；Replaceable buildup slot is fixed conjunction with feed chute by bolt.Monoblock type feed chute is changed to combined type feed chute by the utility model, and the region materials abrasive material that elephant trunk is easiest to abrasion is replaced material mill elephant trunk inner wall, abrasion of the material to elephant trunk inner wall is effectively reduced, improves the service life of feed chute；Interchangeable structure avoids waste caused by integral replacing, has saved cost, improve efficiency convenient for that can replace after abrasion.
Description
Technical field
The utility model relates to a kind of novel feed elephant trunks, belong to ball mill technical field.
Background technique
Ball mill is current the most widely used milling equipment.Generally according to the difference of technique, ball mill is divided into dry method
Grinding and two kinds of wet process powder, wherein wet grinding is widely used in the fields such as metallurgy, mine, chemical industry.Large ore is ground, into
The service life of expects pipe is always the insoluble problem of industry, affects the technological progress of ball mill.Traditional feed chute
Generally steel-casting or ironcasting (as shown in Figure 1): feed chute is mounted on mill feeding end, and upper part connects conveying equipment, under
Portion's straight section protrudes into mill feeding portion bushing, and the material of grinding enters grinding machine from feed chute top, and when charging, material is in elephant trunk
Abrasion is washed away in wall generation, and especially changeover portion erosion rate is most fast, and general some months just needs replacing, and spare parts consumption amount is big, whole
Body replacement elephant trunk must dismantle surrounding devices, especially large-size ball mill, replace heavy workload, replacing construction is long, influences to grind
Machine operation.
Summary of the invention
Technical problem to be solved in the utility model is in view of the defects existing in the prior art, to provide a kind of novel feed
Elephant trunk.
In order to solve this technical problem, the utility model provides a kind of novel feed elephant trunk, including feed chute and can
Buildup slot is replaced, the feed chute is equipped with square aperture in bottom, extends outward along square aperture, at the end of extension
Portion is equipped with square flange；The replaceable buildup slot is square tubular, is equipped with square opening flange in the end of square tube；It is replaceable
Buildup slot is fixed conjunction with feed chute by bolt.
Gasket is placed between the replaceable buildup slot and feed chute.
The feed chute and replaceable buildup slot are steel-casting.
The gasket is acid and alkali-resistance rubber pad.
The utility model has the advantages that monoblock type feed chute is changed to combined type feed chute by the utility model, elephant trunk is easiest to grind
The region materials abrasive material of damage replaces material mill elephant trunk inner wall, is effectively reduced abrasion of the material to elephant trunk inner wall, improves charging and slip
The service life of pipe；Interchangeable structure convenient for abrasion after can replace, avoid waste caused by integral replacing, saved at
This, improves efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of prior art feed chute；
Fig. 2 is the structural schematic diagram of the utility model.
In figure: 1 feed chute, 2 replaceable buildup slots, 3 gaskets.
Specific embodiment
The utility model is specifically described with reference to the accompanying drawings and embodiments.
Fig. 2 show the structural schematic diagram of the utility model.
The utility model provides a kind of novel feed elephant trunk, including feed chute 1 and replaceable buildup slot 2.
The feed chute 1 is equipped with square aperture in bottom, extends outward along square aperture, in the end of extension
Equipped with square flange.
The replaceable buildup slot 2 is square tubular, is equipped with square opening flange in the end of square tube；Replaceable buildup slot
2 are fixed conjunction with feed chute 1 by bolt.
Gasket 3 is placed between the replaceable buildup slot 2 and feed chute 1.
The feed chute 1 is steel-casting, and casting answers that surface is smooth, even tissue, the defect for the intensity that must not have an impact.
The replaceable buildup slot 2 is steel-casting.
The gasket 3 is acid and alkali-resistance rubber pad.
Working principle of the utility model is:
When the utility model at work, part material enters in replaceable buildup slot 2 and is filled with completely, until slipping with charging
1 inner wall of pipe is concordant, this part material replaces the inner wall of feed mill elephant trunk 1, realizes materials abrasive material, alleviates material to elephant trunk inner wall
Abrasion；In replaceable buildup slot 2 after the abrasion that works long hours, it can remove and be replaced, avoid integral replacing and make
At waste.
Monoblock type feed chute is changed to combined type feed chute by the utility model, and the region that elephant trunk is easiest to abrasion is used
Expect that abrasive material replaces material mill elephant trunk inner wall, is effectively reduced abrasion of the material to elephant trunk inner wall, improve feed chute uses the longevity
Life；Interchangeable structure avoids waste caused by integral replacing, has saved cost, improve efficiency convenient for that can replace after abrasion.
The utility model the embodiment above, is merely illustrative, be not it is only, it is all in the scope of the utility model
Or the change in equivalent the scope of the utility model is surrounded by the utility model.
