Description

A kind of cone pump inner tube

Technical field

The utility model belongs to field of metallurgical equipment, specifically a kind of cone pump inner tube.

Background technology

The intact No leakage of cone pump inner tube is the key that cone pump is normally and efficiently run, and the abrasion condition at each position is:It is curved Abrasion is most fast at pipe, and inclined tube abrasion is slightly slow, and horn mouth and straight tube abrasion are most slow.If whole using common tube, need frequently to replace Elbow, often, equipment operating cost is high for maintenance；And if it is whole using heavy wall wear-resistant pipe, inner tube own wt can be caused excessive, And it is costly, when cone pump blows material, pump housing amplitude is larger, be easy to cause inner tube fracture, and material can not convey in pump, Influence overhaul of the equipments, it is often necessary to be manually entered cone pump internal cleaning material, operating environment is severe, and the repair time is long, shadow Ring being smoothed out for production process.

Utility model content

The purpose of this utility model be for above-mentioned technical problem, provide a kind of long service life, equipment operational safety and Low-cost cone pump inner tube.

In order to achieve the above object, the utility model uses following technical scheme：A kind of cone pump inner tube, including loudspeaker Mouthful, which is sequentially connected straight tube, bend pipe and inclined tube, and inclined tube is equipped with inner tube mounting flange, inclined tube far from bend pipe one end Discharge nozzle connecting flange is equipped with far from bend pipe one end nozzle；Wherein, straight tube, bend pipe and inclined tube internal diameter are identical, are arranged on bend pipe Thickness is the first wear-resistant sleeve of 30-46mm, and the first wear-resistant sleeve both ends end is equipped with groove, and straight tube and bend pipe pass through the in groove One connection ring connects, and the first connection ring internal diameter is matched with straight tube outer diameter, and the first connection ring outer diameter is matched with groove internal diameter；Tiltedly The second wear-resistant sleeve that thickness is 24mm is arranged on pipe, bend pipe is connect with inclined tube by the second connection ring in groove, and second connects It connects ring internal diameter to match with inclined tube outer diameter, the second connection ring outer diameter is matched with groove internal diameter.

The beneficial effects of the utility model are：

The utility model using similary internal diameter, but is arranged mainly for the different abrasion condition in each position of cone pump inner tube The pipe fitting of different-thickness wear-resistant sleeve is connected by connection ring, of low cost, is ensured that the transition of inner tube wall is smooth gentle, is carried The high service life of inner tube, reduces maintenance number, ensures the safety and stability production of equipment.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

As shown in Figure 1, a kind of cone pump inner tube, including horn mouth 1, which is sequentially connected straight tube 2, bend pipe 4 And inclined tube 7, inclined tube 7 are equipped with inner tube mounting flange 9 far from 4 one end of bend pipe, inclined tube 7 is equipped with discharge nozzle far from 4 one end nozzle of bend pipe Connecting flange 10；Wherein, straight tube 2, bend pipe 4 and 7 internal diameter of inclined tube are identical, and it is the first resistance to of 30-46mm that thickness is arranged on bend pipe 4 Grinding set 5,5 both ends end of the first wear-resistant sleeve are equipped with groove 11, and straight tube 2 is connected with bend pipe 4 by the first connection ring 3 in groove 11 It connects, 3 internal diameter of the first connection ring is matched with 2 outer diameter of straight tube, and 3 outer diameter of the first connection ring is matched with 11 internal diameter of groove；On inclined tube 7 The second wear-resistant sleeve 8 that thickness is 24mm is arranged with, bend pipe 4 is connect with inclined tube 7 by the second connection ring 6 in groove 11, and second 6 internal diameter of connection ring is matched with 7 outer diameter of inclined tube, and 6 outer diameter of the second connection ring is matched with 11 internal diameter of groove.

The utility model is when specifically used, and after the completion of inner tube is connected as described above, inner tube is passed through inner tube Mounting flange 9 and the discharge port flange of cone pump are fixed, and are passed through discharge nozzle connecting flange 10 and connect inner tube with discharge nozzle, respectively Transition is gentle between pipe fitting, can meet the wear condition demand of different parts, and inner tube whole service life is long.
