Abstract
The utility model relates to a polytetrafluorethylene electric heating tube, which comprises conductive wires, a tube joint and an electric heating tube. The tube joint is composed of a joint cover and a joint seat. The electric heating tube is composed of an outer surface coated with F4 protective sleeve and a metal tube in which a resistance wire is arranged. Both ends of the electric heating tube are arranged in the joint seat. A wiring terminal is inserted in the joint seat. The wiring terminal is connected with the resistance wire and is connected with the conductive wires by a nut. At the surface of the electric heating tube, the utility model is coated with a layer of high temperature resistant and strong corrosion resistant polytetrafluorethylene materials (A temperature can reach 250 DEG C). The utility model solves the defeat of no corrosion resistance of a common metal material electric heating tube. The utility model has the advantages of long service life and better heat conducting performance.
Description
The utility model relates to a kind of heat exchanger, is specifically related to a kind of electric heating tube.
In the prior art field, general employed electric heating tube adopts metal material mostly, though this material thermal conductivity is good, heat-transfer capability is strong, but not acidproof, alkaline-resisting, in the occasion of strong corrosive medium, electric heating tube can be corroded very soon, and make its lost of life, thereby need often to change, use very inconvenience.
The purpose of this utility model is to overcome the prior art defective, and a kind of polytetrafluoroethylene electric heating tube of high temperature resistant, corrosion-resistant, good heat-transfer is provided.
The purpose of this utility model is to realize according to following technical scheme.It comprises lead, pipe joint, electric heating tube, it is characterized in that described pipe joint is made up of connector cover, plinth, and described electric heating tube is coated with F by outer surface
4Sheath, in establish resistance wire metal tube constitute, the electric heating tube two ends all place in the plinth, insert a binding post in it, binding post and the resistance wire nut that linked is connected with lead.
The utility model has solved the not corrosion resistant defective of common metal material electric heating tube owing to coated the polytetrafluoroethylmaterial material (temperature can reach 250 ℃) that one deck is high temperature resistant and be able to bear strong corrosion on the electric heating tube surface, and heat transfer property is better.Simultaneously fit very closely because of its inwall and metal tube outer wall, good heat dissipation effect is difficult for being burnt out, and its structure adopts low surface thermal load to design, and long service life has broad application prospects.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model pipe joint structure figure.
Wherein: the 1-lead; The 2-pipe joint; The 3-electric heating tube; The 4-connector cover;
The 5-binding post; 6-F

The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is made up of lead 1, pipe joint 2, electric heating tube 3, and pipe joint 2 comprises connector cover 4, plinth 8, electric heating tube 3, can curve difformity as required, and two ends place respectively in the plinth 8, and electric heating tube 3 is by F
4Sheath 11, metal tube 9 and the resistance wire 12 that sets within it are formed, and have F high temperature resistant, corrosion resistant premium properties
4The sheath bag is carried out the outer surface at metal tube 9, and makes it to combine closely with metal tube 9 with advanced person's high temperature fusion welding method, to reach the effect of synchronous heat transfer.Metal tube 9 is a thin metallic tubd, has wherein passed through resistance wire 12, fills out the inserts of forming with quartz sand or heavy-burned magnesia 10 between metal tube 9 and the resistance wire 12, play a part to conduct heat, insulate, a binding post 5 is all inserted at metal tube 9 two ends, is a stainless steel bar, one end is provided with screw thread, is inserted in F
4Pad 6 backs are tightened with lead 1 by nut 13 and are joined, and separate with insulation with porcelain duct 7 between binding post 5 and metal tube 9 outlets, and binding post 5 other ends are connected with resistance wire 12.
