Description
Technical field
The utility model relates to induction heating, furthermore, relates to the pipeline induction heater by Current Control.
Background technology
As everyone knows, induction heating equipment is to produce the characteristic frequency induced current, carry out the equipment of induction heating, be used widely industrial, correlation technique application Chinese patent have hundreds of, typically have: CN2275957 number " medium frequency induction heater that is used for locomotive carrying idler " is a kind of equipment of changing locomotive carrying idler; CN2762481 number " numeral shows the bearing induction heater ", has main control circuit to the bearing heating; The CN101401485 of U.S. Inductotherm Corp. number " induction heating equipment of electromagnetic shielding " etc., these patented technologies all have certain induction heating effect, but purposes is more single.
Existing pipeline electromagnetic induction heater and patented technology are fixed coil, control heating by the size and the frequency of Control current, are widely used in the antifreeze and domestic hot water heating aspect of petroleum pipeline.
Summary of the invention
The purpose of this reality invention provides a kind of flexible duct electromagnetic induction heater, and this heater can heat the pipeline of many specifications of various metals, thus its inner liquid substance of water back.
The flexible duct electromagnetic induction heater that the designer provides is made up of tape coil, multi-core socket, multi-pin connector and power line, and an end of tape coil is connected with multi-core socket, and the other end is connected with multi-pin connector; Multi-core socket is connected with power line, and power line is connected with power supply; Tape coil is wrapped on the pipeline that needs heating.
Above-mentioned tape coil is made up of the multicore insulated conductor of 30-50 root, and the multicore insulated conductor is by 5～15 piece 0.3～0.1mms of length at 1m～10m
2Enamel covered wire form, the multicore enamel covered wire at its two ends removes enamelled coating and welds together, and is installed on the core of multi-pin connector and multi-core socket.
Above-mentioned multi-pin connector and multi-core socket adopt the circular or rectangular plug and socket of 30～50 cores; Shell adopts plastic casing.
Lead in the middle of above-mentioned multi-core socket and the multi-pin connector has the band cloth of heatproof outward.
The designer points out that adopting multicore insulation enamel covered wire composition multicore insulated conductor mainly is the influence of considering to reduce kelvin effect, so that can itself lack heating by bigger power current; It mainly is to prevent its heating burnout that shell adopts plastic casing.
The method of attachment of soft pipeline electromagnetic heater flexible belt winding wire is: the two ends of 29 to 49 single multicore insulated conductors are installed in respectively on multi-pin connector and the multi-core socket, the head end of first multicore insulated conductor connects No. 1 terminal of multi-core socket, and its end connects No. 2 terminals of multi-pin connector; The head end of second multicore insulated conductor connects No. 2 terminals of multi-core socket, and its end connects No. 3 terminals of multi-pin connector; The head end of the 3rd multicore insulated conductor connects No. 3 terminals of multi-core socket, and its end connects No. 4 terminals of multi-pin connector; By that analogy, finish, have only No. 1 terminal of multi-pin connector not connect lead at last until the single multicore insulated conductor connection that will select.After the connection, the tail end of power line is connected No. 1 of multi-core socket and last terminal on, so far, form flexible heating circuit.
The operation principle of flexible duct electromagnetic induction heater is: tape coil is wrapped on the pipeline, connect AC power, the sense of current in the many multicore insulated conductors in the tape coil is identical, the electric current superposition, tape coil can produce the power current of powerful direction-agile, be in metallic conduit in the high-intensity magnetic field and produce eddy current effect and generate heat, reach effect wherein liquid heat. as the heating power deficiency, several groups of flexible belt coil electromagnetism induction heaters can be installed more meet the demands.
The designer points out again: the number of turns and length that the varying in size of pipe diameter, tape coil are twined thereon should be different, guaranteeing its impedance within the specific limits, are no more than rated value with its solid conductor electric current after satisfying it and applying power frequency 220V or 380V power supply.
Flexible duct tape coil induction heater of the present utility model, have simple and easy, light, cost is low, be easy to dismounting, removable, do not need controller and the direct advantage of AC power, be fit to the heating of all size metallic conduit, be particularly suitable for on-the-spot pipeline thaw maintenance, pipe insulation, pipeline liquid heating; Also can permanent installation be used for the domestic water heating as long-term heater.
Description of drawings
Fig. 1 is a flexible duct tape coil induction heater structural representation, and Fig. 2 is the schematic diagram of flexible duct tape coil induction heater water back.1 is multi-core socket among the figure, and 2 is multi-pin connector, and 3 is tape coil, and 4 is power line, and 5 is metallic conduit.
Embodiment
It is liquid in the 15mm steel pipeline that embodiment heats diameter
Implement as accompanying drawing 2.Each parts with the coil-induced heater of flexible belt connect earlier: an end of tape coil 3 is connected with multi-core socket 1, and the other end is connected with multi-pin connector 2; Multi-core socket 2 is connected with power line 4; Again power line 4 is connected with power supply.Determine the number of turns that tape coil 3 twines and along the length of pipeline on pipeline 5 according to the diameter of pipeline 5, twine thereon tape coil 3 a few, make it connect that the electric current in the single multicore cable is no more than 20A after the 220V AC power, promptly gross power is no more than 4.4kW.Open AC power, the sense of current in the many multicore insulated conductors in the tape coil 3 is identical, the electric current superposition, and tape coil 3 promptly produces powerful power current, be in metallic conduit 5 in the high-intensity magnetic field and produce eddy current effects and generate heat, reach effect wherein liquid heat.
