DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating heater for piping, and more particularly to a heating heater for piping comprising a heating element for holding piping bent in an L shape or a crank shape .

[0002]

2. Description of the Related Art For example, it is necessary to constantly maintain a pipe at a desired constant temperature so as not to be liquefied due to low temperature in a pipe made of ammonia gas or the like.

Conventionally, when heating a pipe, a linear or belt-shaped heater is wound or attached to the pipe and fixed with a tape or wire to heat the pipe.

[0004]

Therefore, in order to clean the inside of the pipe due to clogging of the pipe, if the heater is removed, it is impossible to use the heater again, and each time a new heater is wound around the pipe. Since it is attached or attached and fixedly attached with a tape or a wire, there is a disadvantage that a large loss is required in terms of time and cost, and that the pipe temperature cannot be made uniform due to uneven winding of the heater.

[0005] That is, in the conventional one, particularly the piping is L-shaped.
If it is bent in a crank shape, (1) it takes time to construct. (2) There is no reproducibility in construction. (3) There is a defect that the temperature of the pipe cannot be made uniform, etc.

The present invention has been made to eliminate the above disadvantages.

Tsu, characterized in that is.

The metal plate has a U-shape, an arc shape, an L-shape or a flat shape.

[0010] The heater is formed by casting a cartridge heater into a sheet heater or a heat conductive plate.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIGS. 1 to 5, a pair of U-shaped metal plates 1 whose inner surfaces are treated to increase radiation efficiency are formed by a pipe 2 which is bent in a crank shape .
1 are disposed on both sides of the linear portion , and at one end of each metal plate 1, an end closing plate 3 made of a sponge-like heat insulating material or a silicone rubber elastic body is inserted between each metal plate 1 and the pipe 2. At the same time, a sheet heater 4 is attached to the outer surface of each of the metal plates 1, and the outer surface of the sheet heater 4 and the exposed surface of the metal plate 1 are surrounded by a sponge-like heat insulator 5, and thus formed. The first of the pipe 2 is formed by the respective heating elements 6a and 6b.
Sandwiched linear portion of, tightened with tightening bands 7, allowed to mounting construction to the first straight portion of the pipe 2.

The sheet heater 4 is formed by, for example, forming a pattern of a nichrome wire or a band, bonding silicon rubber to one or both sides thereof, and drawing lead wires 8 from both ends of the pattern of the sheet heater 4. However, it may be formed by casting a cartridge heater in a heat conductive plate such as an aluminum plate.

The end closing plate 3 can be formed in various ways in conformity with the outer shape of the pipe 2. However, these are not divided into two, and a slit is formed in one place. May be closed.

The other end of the metal plate 1 is connected to a blind plate 9.
So close.

Further , a metal plate in a portion adjacent to the other end portion
Of the pipe 2 in the heat insulating material 5 side and corresponding to the 1
A first heating heater element 10a is formed by making a through-hole through which the bent second pipe portion penetrates from the first pipe portion 2 .

The lower surface of the first heater element 10a
As shown in FIG. 5, the first heater element 10a
It has the same configuration, but the other end is replaced with the blind plate 9
Use the end blocking plate 3 to penetrate the second pipe portion
Of one end of the second heater element 10b thus constructed
The other end has the same structure as that of the first heater 10a.
The upper surface of the third heater 10c is brought into contact with
Therefore, the third pipe portion bent from the second pipe is taken out.
Surround it.

The above is the case where the pipe is bent in a crank shape.
In this case, the pipe is bent in an L-shape.
Is that the third heater 10c can be omitted.
Of course.

[0019]

As described above, the pipe heater of the present invention has a structure as described above.
The surface area of the pipe can be made sufficiently large, so that the wattage per unit area can be reduced and the life of the heater can be prolonged. There are various benefits such as the ability to make the temperature uniform.
