Description

Wear-resistant through air conveying channel elbow

Technical Field

The utility model relates to an abrasionproof air transportation passageway return bend belongs to the dust and collects transport technical field.

Background

The casting shop can produce flue gas dust and the like, and the pneumatic conveying channel is an elbow part of a dust pneumatic conveying device pipeline and is mainly used for conveying the flue gas dust and the like. The dust produced by casting contains fine sand particles, and the sand-containing dust is very seriously abraded to the inner wall of the pipeline in the long-term pipeline conveying process, the abrasion to the inner wall part of the elbow of the pipeline is more serious, even the abrasion condition occurs in the using process, the maintenance needs to be stopped, the time and the labor are wasted, the production efficiency is reduced, and the normal production is influenced.

SUMMERY OF THE UTILITY MODEL

According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: the utility model provides an abrasionproof wears air transportation passageway return bend can avoid the return bend of air transportation passageway to be worn in the use, avoids equipment to shut down, satisfies normal production needs to solve above-mentioned problem.

Abrasionproof air transportation passageway return bend, including the return bend, the return bend periphery is equipped with one section U type groove with return bend looks adaptation, U type groove both ends are equipped with the closure plate.

The utility model discloses add the U type groove of establishing one section and return bend radian, equidimension looks adaptation in the periphery of ordinary return bend, after the return bend position is worn, take sand dust can automatic filling to U type groove in, take sand dust material to fill up the back to material friction material reaches the purpose that the abrasionproof was worn.

The U-shaped groove is internally provided with a plurality of clapboards which divide the U-shaped groove into a plurality of small chambers, and after the corresponding part of the bent pipe is worn, the small chambers can be quickly filled with materials to rub the materials (as shown in figure 2) by the sand-containing dust.

The baffle is evenly distributed in the U-shaped groove.

And concrete is filled in the U-shaped groove. The utility model discloses also can be at the beginning, just fill up concrete or other wear-resisting material in U type inslot, prevent to be worn by the mill, increase of service life.

The two ends of the bent pipe are provided with flange plates, so that the bent pipe can be conveniently connected with other pipelines.

Compared with the prior art, the utility model beneficial effect who has is:

abrasionproof air transportation passageway return bend, simple structure, the preparation is convenient, design benefit. The elbow pipe of the air transportation channel can be prevented from being worn through in the using process, equipment halt is avoided, production efficiency is improved, and normal production requirements are met.

Drawings

Fig. 1 is a schematic perspective view of the present invention;

fig. 2 is a cross-sectional view of a first embodiment of the present invention;

fig. 3 is a sectional view of a second embodiment of the present invention.

In the figure: 1. bending the pipe; 2. a U-shaped groove; 2.1, blocking plates; 2.2, a partition board; 2.3, concrete; 3. a flange plate; 4. carrying sand dust.

Detailed Description

The invention will be further described with reference to the following examples:

the first embodiment is as follows:

as shown in fig. 1 and 2, abrasionproof wear gas transport passageway return bend, including return bend 1, return bend 1 periphery be equipped with one section with return bend 1U type groove 2 of looks adaptation, U type groove 2 welds on return bend 1, U type groove 2 both ends are equipped with closure plate 2.1. A plurality of partition plates 2.2 are arranged in the U-shaped groove 2, and the partition plates 2.2 are uniformly distributed in the U-shaped groove 2. The bent pipe 1 of this embodiment has flanges 3 at both ends. The sand-laden dust 4 can quickly fill the chamber with material to rub the material as the corresponding portion of the elbow is worn through (as shown in fig. 2).

Example two:

as shown in fig. 1 and 3, abrasionproof wear gas transport passageway return bend, including return bend 1, return bend 1 periphery be equipped with one section with return bend 1U type groove 2 of looks adaptation, U type groove 2 welds on return bend 1, U type groove 2 both ends are equipped with closure plate 2.1. Concrete 2.3 is filled in the U-shaped groove 2. The bent pipe 1 of this embodiment has flanges 3 at both ends. When the elbow pipe is manufactured, the concrete 2.3 is filled into the U-shaped groove 2, and after the concrete 2.3 is dried completely, the U-shaped groove 2 is welded to the periphery of the elbow pipe 1.
