Abstract

The invention discloses a liquid heating rod capable of achieving eddy type thermal circulation. The liquid heating rod comprises a flange end. The upper side and the lower side of the flange end are connected with an upper tube body and a lower tube body respectively, wiring posts and a socketed tube are sequentially connected below the lower tube body, at least two wiring posts are arranged at intervals, an inner ring body with internal threads are arranged in the upper portion of the socketed tube, the upper end of each wiring post is connected with a bottom disk of the lower tube body, and the lower end of each wiring post is connected with the upper end face of the inner ring body. The liquid heating rod further comprises a sealing ring, a locking screw, an electrothermal film heating tube and a thermally conductive and insulating tube, wherein the electrothermal film heating tube and the thermally conductive and insulating tube are integrally formed internally and externally. The adjacent area of the electrothermal film heating tube and the thermally conductive and insulating tube are tightly sleeved with the sealing ring, the sealing ring is attached to the inner wall of the lower portion of the socketed tube, the upper end face of the sealing ring is tightly attached to the lower end face of the inner ring body, the locking screw is connected with the inner ring body in a screwed mode, and a screw head of the locking screw tightly abuts against the lower edge of an upper opening of the electrothermal film heating tube. The liquid heating rod is simple in structure, high in thermal efficiency, safe, reliable and durable, and energy is saved.

Description

Can realize the liquid heating rod of eddy current type thermal cycle

Technical field

The present invention relates to heating and put, particularly a kind of liquid heating rod that can realize eddy current type thermal cycle.

Background technology

Modern industry or civil area, to water, oil or other liquid Fast Heating, can be undertaken by various heaters, but the heater element of existing heater, great majority adopt heating wire, thermistor heat generating component or refractory ceramics assembly etc., or the heat efficiency is low, or poor stability, or be not durable very much.The applicant has obtained in No. CN201110124513X " with the liquid heating rod of heating tube with electric heating film " patent of Chinese invention patent mandate, disclosed summary of the invention, although can all reach good effect at aspects such as the heat efficiencys, but structure is comparatively complicated, and the process of liquid in static state heating, liquid upper heat and lower cold often in heating process, the heat efficiency need further raising.

Summary of the invention

The technical problem to be solved in the present invention, is to provide a kind of liquid heating rod that can realize eddy current type thermal cycle, and simple in structure, the heat efficiency is high, and energy savings is safe and reliable, durable in use.

For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of liquid heating rod that can realize eddy current type thermal cycle is provided, comprises flange termination, it is connected with respectively upper tube body and lower tube body up and down, lower tube body below, be connected with away successively terminal and socket pipe, walked terminal and be at least two, space, top in socket pipe, be provided with tapped inner ring body, each walks the upper end of terminal and the chassis of lower tube body is connected, and lower end is connected with the upper surface of inner ring body;

Described liquid heating rod also comprises sealing ring, lock screw, and the heating tube with electric heating film of inside and outside integrative moulding and heat conductive insulating pipe, sealing ring is tightly placed in outside the neighboring region of heating tube with electric heating film and heat conductive insulating pipe, and be close to the lower inner wall of socket pipe, the lower surface of inner ring body is close in the upper surface of sealing ring, lock screw and inner ring body are spirally connected, and the screw terminal of lock screw is tight against heating tube with electric heating film lower edge suitable for reading.

The liquid heating rod that can realize eddy current type thermal cycle as above, flange termination and upper tube body, lower tube body, walks terminal and socket pipe, is that plastic cement is made and one-body molded.

The liquid heating rod that can realize eddy current type thermal cycle as above, sealing ring is that silica gel is made.

Adopt the liquid heating rod that can realize eddy current type thermal cycle of said structure, simple in structure, owing to being provided with some terminals of walking of space, walk the opening existing between terminal, heated liquid is had ready conditions and carry out thermal convection, realize eddy current type thermal cycle, the heat efficiency is high, energy savings, and, by coordinating of sealing ring and inner ring body, heating tube with electric heating film and heat conductive insulating pipe and lock screw, good airproof performance, safe and reliable, durable in use.

Embodiment

Referring to Fig. 1-Fig. 4, a kind of liquid heating rod that can realize eddy current type thermal cycle is provided, comprise flange termination 1, it is connected with respectively upper tube body 2 and lower tube body 3 up and down, and lower tube body 3 belows are connected with away terminal 4 and socket pipe 5 successively, walk terminal 4 and be at least two, this sentences three and describes, and walks terminal 4 spaces for three, has formed altogether three openings 6 between them.Top in socket pipe 5, is provided with tapped inner ring body 7, and each upper end of walking terminal 4 is connected with the chassis of lower tube body 3, and lower end is connected with the upper surface of inner ring body 7.Above-mentioned flange termination 1 and upper tube body 2, lower tube body 3, walk terminal 4 and socket pipe 5, be that plastic cement is made and one-body molded.

Described liquid heating rod also comprises sealing ring 8, the lock screw 9 of silica gel, and the heating tube with electric heating film 10 of inside and outside integrative moulding and heat conductive insulating pipe 11, heat conductive insulating pipe 11 can adopt glass to make, as quartz glass tube, also can adopt ceramic material to make, as zirconia ceramics pipe.Sealing ring 8 is tightly placed in outside the neighboring region of heating tube with electric heating film 10 and heat conductive insulating pipe 11, and be close to the lower inner wall of socket pipe 5, the lower surface of inner ring body 7 is close in the upper surface of sealing ring 8, lock screw 9 is spirally connected with inner ring body 7, the screw terminal of lock screw 9 is tight against heating tube with electric heating film 10 lower edge suitable for reading, by all linked with one another closely cooperating like this, make electrode 12 on heating tube with electric heating film 10 in complete sealing state, can avoid being heated liquid and infiltrate electrode 12 positions, occur to get an electric shock or short circuit accident, can avoid again heat energy to run off to barred body external radiation, safe and reliable.

During heating, liquid heating rod is the part below 1 from flange termination, is all placed in and is heated liquid as water, and power supply wiring is top cover access lower tube body 3 from upper tube body 2, then the electrode 12 of connecting on heating tube with electric heating film 10 through walking terminal 4, and energising starts heating.Cold water enters from the end opening of heating tube with electric heating film 10, and after being heated, hot water rises along heating tube with electric heating film 10, socket pipe 5, and flow out from three openings 6, cold water continues to enter from the end opening of heating tube with electric heating film 10, and hot water continues to flow out from three openings 6, constant, so just formed thermal convection, realized eddy current type thermal cycle, water is by dynamic heat, and the heat efficiency is high, in container, upper and lower water temperature reaches unanimously, and heating effect is splendid.
