Abstract
The utility model discloses a high-efficiency energy-saving electrical radiant tube heater. The high-efficiency energy-saving electrical radiant tube heater comprises a straight cylindrical radiant tube, a heater and a flange, wherein the heater and the flange are arranged inside the radiant tube, and at least one annular partition groove are arranged, on the inner wall of the radiant tube, between the end parts of the heater and the flange. The further improvement of the high-efficiency energy-saving electrical radiant tube heater is that a high-temperature resistant non-metallic material is arranged in the partition grooves. By obstructing heat transmission on the radiant tube, the heating efficiency of the electrical radiant tube heater is substantially increased, energy loss is substantially reduced, and energy is saved.
Description
Technical field
The utility model relates to a kind of electric heater, is specifically related to a kind of for electric furnace electric radiant tube electric heater.
Background technology
The electric radiant tube heater is vitals on electric furnace, generally comprise radiant tube, be arranged on the heater in radiant tube, heater in the radiation tube and tube axially part of correspondence is bringing-up section, and during use, the bringing-up section of radiant tube plays effective radiation heating effect.The radiant tube of prior art electric radiant tube is the straight-tube shape pipe fitting that waits wall thickness, the electric radiant tube of this structure is simple in structure, easily make, but when heating, for waiting straight-tube shape pipe fitting of wall thickness, heater is delivered to heat on whole radiant tube due to radiant tube, the external radiation heating of the bringing-up section of radiant tube not only, and radiant tube causes the mass energy waste except other parts of bringing-up section also external radiation heating, and the efficiency of heating surface is low.
The utility model content
The utility model provides a kind of efficiency of heating surface high for the deficiencies in the prior art, the high-efficiency and energy-saving type electric radiant tube heater of energy savings.
The utility model is achieved through the following technical solutions technical goal.
High-efficiency and energy-saving type electric radiant tube heater comprises the straight-tube shape radiant tube, is arranged on heater and flange in radiant tube; Its improvements are: described radiant tube in the heater end together with being provided with at least on inwall between flange annular partition grooves.
The utility model further improves and is: be provided with high temperature resistant nonmetallic materials in described partition grooves; The utility model further improves and is: described high temperature resistant nonmetallic materials are refractory ceramics mud.
The utility model further improves and is: described radiant tube is provided with twice annular partition grooves on the inwall between heater end and flange.
The utility model further improves and is: bottom one partition grooves is arranged on the axial location corresponding with the heater end.
The utility model further improves and is: described radiant tube (1) is seamless high-temperature alloy pipe.
The utility model compared with prior art has following good effect:
1, radiant tube in the heater end together with being provided with at least on inwall between flange annular partition grooves, like this, in use, partition grooves plays blocking effect, significantly reduces the effect that heat transmits, and has significantly improved the efficiency of heating surface, also significantly reduce energy loss, saved the energy; Certainly, set partition grooves is more, and the blocking effect that is risen is more obvious.
2, be provided with high temperature resistant nonmetallic materials in partition grooves, play further partition effect, further reduce the heat transmission.
3, partition grooves is arranged on the axial location corresponding with the heater end, and by the external radiation heating of bringing-up section of radiant tube, the efficiency of heating surface is higher basically.
4, radiant tube is seamless high-temperature alloy pipe, can make electric radiant tube that arranged long useful life.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the local enlarged diagram of I part in Fig. 1.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments for the below.
High-efficiency and energy-saving type electric radiant tube heater shown in the drawings comprises straight-tube shape radiant tube 1, is arranged on heater 2 and flange 3 in radiant tube 1; Radiant tube 1 in heater 2 ends together with being provided with at least on inwall between flange 3 annular partition grooves 1.1, in order to obtain barrier effect preferably, bottom one partition grooves 1.1 is arranged on the axial location corresponding with heater 2 ends; In the present embodiment, radiant tube 1 is provided with twice annular partition grooves 1.1 on the inwall between heater 2 ends and flange 3.In order to improve the partition effect, the utility model is provided with high temperature resistant nonmetallic materials 4 in partition grooves 1.1, and in the present embodiment, high temperature resistant nonmetallic materials 4 are refractory ceramics mud.
In order effectively to extend useful life of the present utility model, in the present embodiment, radiant tube 1 adopts seamless high-temperature alloy pipe.
