The internal diameter of tube-like envelope described in the utility model is greater than the external diameter of outer ceramic heat circle, the internal diameter of sleeve pipe is greater than the external diameter of internal layer ceramic heat circle, the length of described internal layer ceramic heat circle is less than the length of core pipe, the length of described outer ceramic heat circle is less than the length of sleeve pipe, and described sleeve pipe and core Guan Jun are arranged in cantilever fashion; This is to ensure that tube-like envelope, sleeve pipe and core pipe are mutually nested in the mode of matched in clearance from outside to inside, is communicated with into three layers of end to end gas channel.
In addition, the tube-like envelope in the utility model, sleeve pipe, core Guan Sangen diameter are that the pipe of stepped change is linked together by left and right end cap and left and right flanges, dexterous in mutually nested mode, fit together quickly; Meanwhile, internal layer ceramic heat circle realizes the combination with left end cap by ring set at the outer surface of core pipe, and outer ceramic heat circle realizes the combination with right end cap by ring set at the outer surface of sleeve pipe; Therefore, by dismounting left end cap or right end cap, can quickly internal layer ceramic heat circle or outer ceramic heat circle be extracted out from tube-like envelope, convenient maintenance.
Principle of the present utility model is as follows:
The utility model in use, cold air enters in the interlayer of tube-like envelope and sleeve pipe from air inlet pipe, right-to-left flows, enter in the interlayer of sleeve pipe and core pipe after outer ceramic heat circle heating, flow from left to right, after outer ceramic heat circle and internal layer ceramic heat circle Bilateral heating, enter core tube cavity, right-to-left flowing again, hot gas flows out from escape pipe after again being heated by internal layer ceramic heat circle again in the process.
The beneficial effects of the utility model are as follows:
Cold air successively can carry out three Cheng Jiare through three layers of end to end gas channel, substantially increases the thermal efficiency, achieves gas and be rapidly heated, and economize energy, meets requirement of experiment.In addition, the utility model rational in infrastructure, be convenient to dismounting maintenance, extend service life of electric heater.

Detailed description of the invention
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1, bushing type electric heater of the present utility model comprises the tube-like envelope (3) of two ends with left and right flanges (2,5), be connected with left and right flanges (2,5), shutoff at the left and right end cap (1,6) at tube-like envelope (3) two ends, the right-hand member of tube-like envelope (3) is provided with air inlet pipe (4); Shoulder hole is processed with in described left end cap (1) center, its small aperture section is fixedly fitted with outward extending escape pipe (11), large aperture section is fixedly fitted with the core pipe (10) extended internally, have internal layer ceramic heat circle (9) at the outer surface ring set of described core pipe (10), described internal layer ceramic heat circle (9) is connected with binding post I (12) electricity be arranged on left end cap (1); Sleeve pipe (7) is fitted with at the groove blind hole internal fixtion of described right end cap (6) inner surface center processing, have outer ceramic heat circle (8) at the outer surface ring set of sleeve pipe (7), described outer ceramic heat circle (8) is electrically connected with the binding post II (13) be arranged on right end cap (6); Described tube-like envelope (3), sleeve pipe (7) and core pipe (10) are mutually nested in the mode of matched in clearance from outside to inside, surround three layers of end to end gas channel from air inlet pipe (4) to escape pipe (11).
The internal diameter of tube-like envelope described in the utility model (3) is greater than the external diameter of outer ceramic heat circle (8), the internal diameter of sleeve pipe (7) is greater than the external diameter of internal layer ceramic heat circle (9), the length of described internal layer ceramic heat circle (9) is less than the length of core pipe (10), the length of described outer ceramic heat circle (8) is less than the length of sleeve pipe (7), and described sleeve pipe (7) and core pipe (10) are arranged all in cantilever fashion.This is mutually nested in the mode of matched in clearance from outside to inside in order to ensure tube-like envelope (3), sleeve pipe (7) and core pipe (10), is communicated with into three layers of end to end gas channel.
