Description

Elbow for sending line for raw materials

The present invention relates to an elbow for a raw material transfer line, and more particularly, improves durability by improving elbow which is a bent portion of a piping line for transferring a raw material requiring abrasion resistance such as sand, which is a raw material of glass, by oil or pneumatic, to improve durability. To contribute to the smoothness.

The transfer of raw materials that require extreme wear resistance, such as sand, ceramics, and iron ore, which are the raw materials for glass, is carried by pipelines supplied with oil and pneumatics.

Most of the raw material transfer line as described above is of pipe type, and the straight line and the direction change line are installed in parallel.

Conventional pipelines for supplying such raw materials are mostly configured to connect metal pipes with flanges.

Such a conventional pipeline is briefly shown in FIGS. 1 and 2 and looks at it as follows.

The conventional pipeline 1 consists of a straight line 2 and a curved line 3 and has a flange 4 for connection at both ends of these straight and curved lines 2 and 3, and has a curved line ( 3) the elbow 5 is used a lot.

When the raw material is transferred to the elbow applied to the curved line for the change of direction in the pipeline as described above, intensive friction and load occurs at the portion (R) where the actual direction is changed.

In particular, since the raw material conveyed through the pipeline is an extremely wear-resistant raw material, damages such as the formation of holes are easily and quickly worn out from other areas where friction and load occur.

When the hole is formed in the elbow of the redirection line as described above, oil and pneumatic leaks to help the transfer of the raw material is leaked to reduce the transfer force of the raw material.

The oil and pneumatic pressure to help the transfer of the raw material and the raw material through the pipeline is leaked to the outside of the pipeline to contaminate the surroundings, as well as causing dust if the raw material to be transported is fine powder. Has the problem.

In addition, since the entire operation of the raw material transfer line must be stopped in order to replace a damaged pipeline, only a damaged part is used for emergency treatment as a temporary measure, and thus, permanent measures are urgently needed.

In particular, the continuous load on the damaged and first-aid pipelines may impede the transfer of raw materials and, as a result of the vicious cycle where the same parts are damaged, the first-aid treatment is used again. It's a bad situation and we can't find a clue to fundamental problem solving.

In the present invention, to improve the elbow connected to the direction change of the raw material transfer line as invented to solve the above problems to increase the wear resistance by the oil and pneumatic pressure of the raw material and the raw material transfer auxiliary means to improve the transfer capacity of the raw material It aims to improve and secure stable durability.

In the present invention, the elbow 35 connected to the straight line 31 of the pipeline 30 for transferring the raw material requiring wear resistance and the turning line 32 between the straight line 31 is improved to improve the raw material and air pressure. It is characterized in that to increase the wear resistance by ensuring a stable durability to improve the transfer capacity of the raw material.

In the present invention, the elbow 35 is composed of a liner 36 which is in contact with the raw material to be transferred and a case 37 which protects the liner 36 from the outside of the liner 36 and is connected to the straight line 31. .

The liner 36 is located at the rear of the transfer passage 38 and the transfer passage 38 so that the raw material can be transferred integrally with the hydraulic pneumatic passage 39 for receiving oil and pneumatic pressure to assist the transfer of the raw material. Form to have.

On the side of the transfer path 38 of the liner 36 has a large transfer load, it may be desirable to have a thick portion 40 to maintain durability higher than the surroundings.

The material of the liner 36 is formed by melt casting alumina, zirconia and silica.

In the case of using the melt-casting material as the liner 36, a structure having a strong bonding force is formed during the crystallization and cooling of the melt-casting material so that it has high strength and sufficient abrasion resistance, high temperature heat resistance and chemical resistance. There are characteristics.

The case 37 has a flange 41 on both sides so as to be connected to the straight line 31, and has a receiving space 42 having the same shape as the liner 36 to accommodate the liner 36. It is equipped with.

The liner 36 and the case 37 complete the elbow 35 by using a mortar 45 to maintain a firm adhesive state.

6 and 7 show another example of the elbow 35 of the present invention, which illustrates a case in which a pneumatic pneumatic passage 39 for assisting raw material transfer is not formed.

The elbow 35 of the present invention as described above is applied to the direction conversion line 32 between the straight line 31 and the straight line 31 of the pipeline 30 for the raw material transfer as in the prior art to transfer the raw material. Used.

As described above, even when the raw material, in particular, a raw material requiring abrasion resistance, is supplied with oil and pneumatic pressure as a transport aid, the elbow 35 is easily worn or damaged due to abrasion (holes are formed, etc.).

Since alumina, zirconia, and silica are formed by melting and casting the abrasion resistance of the liner 36 included in the case 37 constituting the elbow 35 and having high temperature heat resistance and chemical resistance, wear resistance is required. Even if the raw material is transferred, it is not easily worn out.

The present invention as described above can be improved by the characteristics of the liner 36 to improve the conveying force of the raw material while increasing the life of the elbow 35, as well as the raw material transport according to the maintenance of the elbow 35 It can be characterized by minimizing the revolving factor.

The present invention as described above can improve the elbows connected to the direction change portion of the raw material transfer line for transferring the raw material required to wear resistance to increase the wear resistance by the raw material to improve the transfer capacity of the raw material and ensure stable durability, etc. Various effects can be obtained.
