Background

The electric heater is a device which is internationally popular and converts electric energy into heat energy, since a power supply can generate a thermal effect through a resistance wire, a plurality of inventors are engaged in the research and manufacture of various electric heating appliances in the world, the electric heating is a process of converting electric energy into heat energy and is used for heating, preserving heat and heating flowing liquid and gaseous media, when the heating media pass through a heating cavity of the electric heater under the action of pressure, the heat generated in the working of an electric heating element is uniformly and reasonably transmitted by adopting the fluid thermodynamic principle, so that the temperature of the heated media reaches the process requirements of users;

electric heaters are widely used in heat treatment processes, and are used very much in heat treatment furnaces, but the current heaters have several disadvantages: the heat loss is relatively high; the integration rate is low, and the heating efficiency on a single heater is low, so that the use cost is high, and the maintenance difficulty is high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's defect, provide heater for heat treatment furnace, through setting up dead lever and fixed disk, install the resistance wire of a plurality of "n" style of calligraphy on the fixed disk, and a plurality of resistance wires encircle the dead lever setting, and then improve the efficiency of heating of single heater, reduce use cost, reduce and maintain the degree of difficulty, through setting up the insulating tube, insulating tube and heat treatment furnace looks adaptation, and then reduced the thermal loss in the heating furnace.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

heater for heat treatment furnace, including the insulating tube, the top fixedly connected with dead lever of insulating tube, a plurality of fixed disk of fixed connection on the length direction is followed in the outside of dead lever, the inside fixedly connected with a plurality of resistance wire of fixed disk, the resistance wire sets up along the length direction of fixed lever, just the resistance wire is "n" style of calligraphy, the resistance wire of "n" style of calligraphy encircles the fixed disk.

Preferably, the bottom of the heat preservation pipe is fixedly connected with a fixing block.

Preferably, the top of the fixing rod is fixedly connected with a guide post, the guide post is in a circular truncated cone shape, and the guide post and the fixing rod are made of the same material.

Preferably, the fixed disk is cylindrical, and the outer side of the fixed disk is provided with a protruding block, and the protruding block surrounds the fixed disk for a circle.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. by arranging the fixing rods and the fixing disc, the plurality of n-shaped resistance wires are arranged on the fixing disc and are arranged around the fixing rods, so that the heating efficiency of a single heater is improved, the use cost is reduced, and the maintenance difficulty is reduced;

2. through setting up the insulating tube, insulating tube and heat treatment furnace looks adaptation, and then reduced the loss of heat in the heating furnace.

Detailed Description

The following will further describe the specific embodiment of the heater for heat treatment furnace according to the present invention with reference to fig. 1 to 4. The heater for a heat treatment furnace of the present invention is not limited to the description of the following embodiments.

The specific structure of the heater for the heat treatment furnace is provided in the present embodiment, as shown in fig. 1-4, the heater comprises a heat preservation pipe 1, a fixing rod 2 is fixedly connected to the top of the heat preservation pipe 1, and a plurality of fixing disks 3 are fixedly connected to the outer sides of the fixing rods 2 along the length direction;

the inner part of the fixed disc 3 is fixedly connected with a plurality of resistance wires 4, the resistance wires 4 are arranged along the length direction of the fixed bar 2, the resistance wires 4 are n-shaped, the n-shaped resistance wires 4 surround the fixed disc 3, and the bottom of the heat preservation pipe 1 is fixedly connected with the fixed block;

the top fixedly connected with guide post 5 of dead lever 2, and guide post 5 is the round platform type, and guide post 5 and dead lever 2 are made by the same kind of material, and fixed disk 3 is cylindricly, and the outside of fixed disk 3 is provided with protruding piece, and protruding piece encircles 3 a week of fixed disk.

By adopting the technical scheme:

through setting up dead lever 2 and fixed disk 3, the resistance wire 4 of a plurality of "n" style of calligraphy is installed to the installation on fixed disk 3, and a plurality of resistance wires 4 encircle dead lever 2 and set up, and then improve the heating efficiency of single heater, reduce use cost, reduce the maintenance degree of difficulty, set up protruding piece and conveniently place this device.
