Abstract

The utility model provides a ceramic electrothermal tube, in particular to an electrothermal tube taking the ceramic as the heating body. Essentially, a plurality of ceramic heating sheets are serially arrayed and clamped by two metal splints as well as being tightly packed by temperature-resistant insulation material to form a ceramic heating rod; and one or more than one ceramic heating rods are selected to be planted into an aluminium rod, namely being capable of embedding into the two parallel tube diameters of the heating external tube, forming a ceramic electrothermal tube. As the ceramic has characteristics of low temperature low resistance and high temperature high temperature, the utility model has advantages of low failure rate and constant high temperature as well as promising the operation safety.

Description

Ceramic electrical heating tube

Technical field

The utility model designs about a kind of electrothermal tube, refers to that especially a kind of is to select the ceramic electrical heating tube of pottery as heater for use.

Prior art

The known electric heat pipe is formed, and mainly is the heating filament in caliber inwall heeling-in circle coiled type, after energising, utilizes the high heat of heating filament generation and is sent to the heating outer tube to be engaged in heating work; But the known electric heat pipe very easily burns damage because of the overheated resistance wire that causes, and particularly can fuse moment when sky burns, and not only failure rate is higher for it, and also potential in the use have a hidden danger.

Goal of the invention

The utility model main purpose, be to be to provide a kind of with the ceramic electrical heating tube of pottery as medium, it utilizes ceramic heating to have high hot thermostatic characteristics, reaches the reduction failure rate by this, provide the effect of safety in utilization, and its whole composition also claims to simplify and cost is relatively low honest and clean.

Embodiment of the present utility model is: coat above-mentioned ceramic heating plate but plural number is had the ceramic heating pipe that thin conductive metal layer coats with metal splint, totally coat with the high-temperature insulation material that can reel again and constitute a ceramic heating bar, imbed the heating outer tube, ceramic heating plate produces high temperature and is passed to outer heating tube in regular turn during energising.

Specific embodiment

As shown in Figure 1 to Figure 3, " ceramic electrical heating tube " design that the utility model is done, it mainly comprises: members such as ceramic heating plate 1, metal splint 2, aluminum strip 3 and heating outer tube 4; Wherein: ceramic heating plate 1, as shown in Figure 4, it is with 1 one-tenth of a plurality of ceramic heating plate row string row, this ceramic heating plate 1 is all established conductive thin metal layer 11 in two-sided; Metal splint 2, can adopt aluminium and make strip, it is ceramic heating plate 1 clamping for above-mentioned one-tenth row string row, bestow tight parcel and constitute a ceramic heating bar (as shown in Figure 5) with selected heatproof insulation material 5 again, this metal splint 2 also is provided with up and down the wire clamp 21 of dislocation respectively at an end, connects for conductor wire 6; Aluminum strip 3, be to be single cylindricality aluminum strip according to need, or shown in figure embodiment, be to form with aluminum strip 3 merging of two upper and lower separation, the all default spatial accommodation 31 of the central authorities of this upper and lower aluminum strip 3 is implanted in conjunction with (as shown in Figure 6) for one or more ceramic heating bar;

Before be referred to as upper and lower aluminum strip 3, the corresponding surface that its merging inserts and puts is to have to be any abnormity coupling male and fomale(M﹠F) design that agrees with relatively, uses that to guarantee that the ceramic heating bar is implanted clamping more fastening:

Heating outer tube 4, its shape is moulding according to the demand of electrothermal tube, makes the upper and lower aluminum strip 3 of above-mentioned clamping ceramic heating bar can corresponding imbed two parallel calibers 41 of this heating outer tube 4 to constitute;

The as above ceramic electrical heating tube of Zu Chenging, the characteristic that has low temperature low resistance and high temperature high value because of pottery, so when energising, can make the ceramic heating plate 1 that composes in series produce the high temperature heating, and with high temperature be sent to rapidly the heating outer tube 4, in order to carrying out heating work, only when arrival high temperature is critical, (for example can in processing procedure, be set at 260 degrees centigrade or any high temperature) by ceramic heating plate, because of the resistance of ceramic heating plate 1 very big, promptly present as off-position, so it is constant that high temperature heat will stop to form high temperature automatically, is low with failure rate, and the fail safe of using is higher, and simplify owing to form, its cost is also cheaper relatively.

In like manner, as above-mentioned row with 1 one-tenth row string of a plurality of ceramic heating plates is the heater that strip is formed, it is in case of necessity from making this ceramic heating plate directly make single strip piece, and then all establish conductive thin metal layer in this single strip ceramic heating plate two-sided and get final product, only this, pure is to decide on actual manufacturing, necessity that there is no particular restriction.

In sum, this utility model ceramic electrical heating tube, its structure is compared with the prior art structure, has improved it The deficiency that exists on the existing structure has reached the inventor's goal of the invention.
