Description

DETAILED DESCRIPTION OF THE INVENTION [Fields of Application in: 1] This invention relates to a transport pipe that is applied when transporting fine particles such as crushed coal and sand using high-speed air currents.

[Prior art and its problems]

In piping that transports fine particles such as crushed coal and sand by circulating high-speed air currents, the inner walls of the pipes are subject to significant wear due to contact LA rubbing, especially in curved pipes, as the objects to be transported are hard particles. When changing direction, centrifugal force acts, and the transported material is separated from the airflow, or concentrated drift occurs, mainly inside the outside of the curved pipe. As a result of the violent collision throughout the prefecture, the wall thickness of the tube progressed, and eventually the VC developed a hole.

Therefore, as a countermeasure, it is possible to thicken the pipes in the parts where wear and tear is particularly likely to occur, or to use pipes made of materials with excellent wear resistance, but in either case, the outstanding effect is Period, I can't be a samurai.

[Purpose of the invention]

In view of the above-mentioned actual situation, the present invention has been made to
This was done for the purpose of providing an effective dipping pipe.

[Structure of the invention]

The transport pipe according to the present invention is characterized in that the core material is paper material or net material capable of forming the required 'a-shaped body, and the pipe is constructed by wrapping adhesive tape inside and outside the core material. be.

[Implementation row]

The drawings show one embodiment of the present invention, which will be explained in order below.

In other words, Fig. 1 shows a transport tube (A) made up of 44 layers of adhesive tape (1) wrapped around it in multiple layers. The adhesive tape (1) is then wrapped in multiple layers while bending its edges, or, although not shown, an adhesive thin cloth material or granular foil 12 having a predetermined width is polymerized. It is manufactured by winding this into a cylinder and wrapping tape over it.

In addition, Fig. 2 shows that the base material is a so-called 'α body (3) that does not have wear resistance, which is predicted to cause wear, thinning, and hole breakage.
A transport pipe (B) is constructed by wrapping an adhesive tape (1) around its outer periphery, and this embodiment shows a case where it is applied to a curved portion of a transport route. The pipe body (3) of this transport pipe (3) is merely used as a means to facilitate the construction of a bent pipe of adhesive tape.

The transport pipe (0) shown in Fig. 3 can be constructed by appropriately combining a large number of steel wires or by using a rigid mesh material (for example, lath wire mesh, etc.).
is used as a core material (4), first, when the core material (4) is unfolded, one or more layers of double-sided adhesive tape (5) are attached to the inner surface of the core material (4), and when this is bent into a tubular shape, adhesive tape is attached to the outer periphery of the core material (4). It is manufactured using the procedure of winding (6).

It goes without saying that the base material (3) and the core material (4) may be made of plastic or other plywood materials with excellent bendability. In addition, when using this transport R by b-light, measures such as attaching reinforcing members to the outer periphery of parts 1cjd that particularly require strength are taken.

The transport pipe of the present invention has the structure as described in the embodiments69 above, and when this is used as a transport pipe for fine particulate matter by commercial airflow, the transported material is transported on the inner circumferential wall at the initial transport stage. The inner surface of the bent tube becomes coated with the transport substance by 1%. Therefore, the subsequently transported substances do not come into direct contact with the pipe wall.

A so-called mutual contact phenomenon of substances will occur.

〔Effect of the invention〕

According to this invention, an adhesion layer of the substance to be transported is formed on the inner wall of the transport pipe, which effectively prevents direct frictional wear and tear of the pipe due to the transport substance, thereby extending the life of the pipe. can be named. Furthermore, the transport pipe according to the present invention can be provided with particular safety, and furthermore, even if a hole occurs, the repair is extremely easy, as it is sufficient to additionally wrap the hole with adhesive tape.
