Abstract

The utility model relates to a wear-resistant bent pipe which comprises a slipping pipe, wherein an L-shaped plate is fixed at the turning joint of the slipping pipe, the two ends of the L-shaped plate are closely connected with the slipping pipe; and the width of the L-shaped board is the same with the diameter of the slipping pipe. The wear-resistant bent pipe provided by the utility model has the advantages of simple structure, convenience in manufacture and low cost, can achieve an excellent wear-resistant effect under the condition of not changing the clear opening of the slipping pipe, and prolongs the service life of the slipping pipe.

Description

A kind of abrasion-proof bent tube

Technical field

The utility model relates to a kind of abrasion-proof bent tube, relates in particular to a kind of abrasion-proof bent tube for sand under dry sand.

Background technique

In the dry mortar mixing plant industry, the wear-resisting measure that take in lower sand Elephant trunk turning joint place has following several: the local elephant trunk thickness that strengthens; The part is used high-abrasive material instead; Add the weldering wearing layer in inside, joint; Add some horizontal reinforcement bars of weldering in inside, joint, make it have material between reinforcement bar and reach wear-resisting purpose.Because the chiseling property of mill of sand is very strong, particularly at the larger turning of drop, its wearing and tearing are very fast, and the wear-resisting effect of above measure is all not ideal; And exist as high in cost, make and the deficiency such as bother, the elephant trunk latus rectum reduces.

Summary of the invention

For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of abrasion-proof bent tube, and is simple in structure, is convenient to make.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of abrasion-proof bent tube comprises elephant trunk, is fixed with L shaped plate in the Elephant trunk turning joint, and L shaped plate two ends are connected with the elephant trunk sealing by gusset; Described L shaped plate width is identical with the elephant trunk diameter.

Compared with prior art, the beneficial effects of the utility model are:

Simple in structure, to be convenient to make, cost is low, does not change the elephant trunk latus rectum and just can reach good wear-resisting effect, prolongation elephant trunk working life.

Description of drawings

Fig. 1 is structural representation of the present utility model (basic model).

Fig. 2 is structural representation of the present utility model (extended pattern).

In figure: 1-gusset 2-L shape plate 3-elephant trunk 4-heap sand is regional.

Embodiment

Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following mode of execution.

See Fig. 1, Fig. 2, a kind of abrasion-proof bent tube comprises

elephant trunk

3, and 3 turning joint places are fixed with L shaped plate 2 at elephant trunk, and L shaped plate 2 two ends are sealed with elephant trunk 3 by gusset 1 and are connected; Described L shaped plate 2 width are identical with the elephant trunk diameter.

Embodiment 1:

During making, outside at elephant trunk 3 turning joint places, L shaped plate 2 of shape welding along with elephant trunk 3, its width equals the diameter (the rectangle elephant trunk equals the elephant trunk width) of elephant trunk 3, seal up with gusset 1 at the two ends of L shaped plate 2, described gusset welds along (center line) along the outer diameter side of elephant trunk, forms the space of a sealing, sees Fig. 1.

Embodiment 2:

During making, outside at elephant trunk 3 turning joint places, L shaped plate 2 of shape welding along with elephant trunk 3, its width equals the diameter of elephant trunk 3, and seal up with gusset 1 at the two ends of L shaped plate 2, and described gusset, L shaped plate are also the parts of elephant trunk 3, intersecting line welding along elephant trunk, lower end surface weldering one dome, Fig. 2 is seen in the space of a sealing of formation.

Form the space of a sealing between L shaped plate 2 and gusset 1 and lower sand elephant trunk 3, the chiseling property of mill of slipping due to sand is very strong, and certain kinetic energy is arranged, elephant trunk 3 turning joint places will soon be met sand face mill and leak, at this moment, sand will flow between L shaped plate 2, gusset 1 and lower sand elephant trunk 3 in formed space, form heap sand zone 4, when follow-up sand continues to fall, just can not directly impact the elephant trunk surface, and fall above the sand in heap sand zone 4, realized the purpose with the material abrasive material.Pile up what of sand, depend on the angle of repose of size, angle and the sand of elephant trunk 3.

The utility model is simple in structure, is convenient to make, and cost is low, does not change the elephant trunk latus rectum and just can reach good wear-resisting effect, prolongation elephant trunk working life.

Claims

1. an abrasion-proof bent tube, comprise elephant trunk, it is characterized in that, is fixed with L shaped plate in the Elephant trunk turning joint, and L shaped plate two ends are connected with the elephant trunk sealing by gusset.

2. a kind of abrasion-proof bent tube according to claim 1, is characterized in that, described L shaped plate width is identical with the elephant trunk diameter.
