Description

High-efficient electrothermal tube

Technical Field

The utility model relates to a heating pipe.

Background

The heating pipe is formed by filling an electric heating wire into a seamless metal pipe (a carbon steel pipe, a titanium pipe, a stainless steel pipe and a copper pipe), filling magnesium oxide powder with good heat conductivity and insulativity into a gap part, then shrinking the pipe, and processing the pipe into various shapes required by a user; the heating device has the advantages of simple structure, high thermal efficiency, good mechanical strength, good adaptability to severe environment and the like, and is widely applied to heating of various liquids and acid-base salts and metals with low melting points (lead, zinc, tin and babbit alloy) due to simple manufacturing process, low price, convenient use, convenient installation and no pollution. Generally, in order to increase the heating speed and efficiency, the heating tube is processed into a U shape, so that the length of the tube body actually and effectively heated exceeds the straight tube with the same height, and the heating efficiency is far higher than that of the straight tube. However, in order to pursue higher heating efficiency, more U-shaped pipes need to be inserted into the fixed plate, which causes more holes to be drilled on the fixed plate for inserting more U-shaped pipes, which results in a reduction in the safety distance between the heating pipe joints, and a reduction in the safety of the heating pipe.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a high-efficient electrothermal tube can effectively increase pipe shaft length, promotes heating efficiency and speed to ensure to have reliable safe distance between the heating tube joint, promote the security.

In order to achieve the purpose, the utility model provides a high-efficient electrothermal tube, which comprises a fixed disk, it is equipped with external heating pipe to insert on the fixed disk, external heating pipe is provided with one to outer J type pipe and outer U type pipe, the end of buckling of outer J type pipe links to each other with the both ends of outer U type pipe respectively, the vertical end of outer J type pipe stretches out the fixed disk and links to each other with the outer joint.

Compared with the prior art, the utility model has the advantages that the effective pipe body of the heating pipe comprises two J-shaped pipes and two U-shaped pipes, compared with U-shaped pipes with equal height and width, the actual heating length of the heating pipe far exceeds that of the U-shaped pipe, and only one single pipe is needed, only two joints are needed, the safety distance of the joints between the fixed disks is larger, and the safety is good; the length of the pipe body can be effectively increased. Promote heating efficiency and speed to ensure that there is reliable safe distance between the heating tube joint, promote the security, the utility model discloses can be used for the heating of liquid.

As a further improvement, the fixed disk is provided with an inner heating pipe, the inner heating pipe is provided with an inner J type pipe and an inner U type pipe, the bending end of the inner J type pipe is respectively connected with the two ends of the inner U type pipe, the vertical end of the inner J type pipe stretches out the fixed disk to be connected with the inner joint, so that a plurality of heating pipes can be added on the fixed disk, and the heating efficiency and the heating speed are further improved.

As the utility model discloses a further improvement, interior heating pipe sets up between the outer heating pipe, and interior heating pipe is in between the outer heating pipe like this, and the space that actually occupies still only the outer heating pipe accounts for the space, can practice thrift the whole shared space of heating pipe effectively to can make the heat that the heating pipe gived off more concentrated, further promote rate of heating and efficiency.

As a further improvement, it is provided with a pair ofly to have the outer heating pipe to be provided with the symmetry on the fixed disk, the inner heating pipe is provided with the symmetry on the fixed disk and is provided with a pair ofly, is used for on the heater that needs greater heating power like this, not only can greatly promote the heating, moreover safe and reliable.
