Description

Technical Field

[0001] The utility model relates to the technical field of induction coils, in particular to a connection structure between a coil copper tube and a water cable. Background Art

[0002] The induction furnace is the most efficient, fastest, low-consumption, energy-saving and environmentally friendly induction heating equipment for heating metal materials. The working principle of the induction furnace is mainly based on Faraday's law of electromagnetic induction and the electromagnetic induction phenomenon. The main principle is to use the furnace's medium-frequency power supply frequency conversion device to convert the three-phase 50Hz alternating current into a single medium-frequency current of 100Hz--8000Hz through rectification and inversion. After inputting it into the induction coil, a high-density magnetic field is generated. The magnetic field cuts the metal in the induction coil to generate eddy currents and heat itself, thereby achieving the purpose of metal heating.

[0003] The common way to connect the induction furnace to the power supply is to tighten the energized part of the water cable to the copper busbar with screws. However, this method has disadvantages. When the screws are loose, sparks will occur when the current passes through the copper busbar.

[0004] Based on the above reasons, it is necessary to improve the existing technology. Utility Model Content

DETAILED DESCRIPTION

[0019] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] See also Figure 1-3A connection structure of a coil copper tube and a water cable, comprising an induction coil body 1 and a coil joint structure 2 arranged on the induction coil body 1, the coil joint structure 2 comprising a coil water cable joint 20 and a coil water pipe joint 21 arranged on the induction coil body 1, the coil water cable joint 20 being connected to the water cable by a threaded connection, the coil water pipe joint 21 being connected to the water pipe, the coil water cable joint 20 comprising a copper tube 200 for powering on and a water pipe 201 arranged in an inner cavity of the copper tube 200 for passing water, the water cable 3 comprising an interface 30, a water passing part 31 arranged at one end of the interface and connected to the water pipe 201, an electric part 32 sleeved on the water passing part 31 and a fixing ring 33 for fixing the electric part 32, the water passing part 31 being connected to the water pipe 201, the electric part 32 conducting and transmitting current to the copper tube 200 through the interface 30.

[0021] In the above structure, a coil water cable connector is used to directly connect the interface method of the water cable, so that the water pipe is connected to the water-passing part of the water cable for conveying water flow, and the copper tube is threadedly connected to the interface. The power-carrying part at the rear end transmits current to the copper tube through the conductivity of the interface, which effectively prevents the screws fixing the copper busbar and the cable from loosening when the copper busbar transmits current, thereby causing sparks. It effectively avoids the occurrence of accidents caused by current sparks, and at the same time, the design of removing the copper busbar can reduce manufacturing costs.

[0022] Specifically, the coil water cable connector 20 and the coil water pipe connector 21 are symmetrically distributed and there are at least two of them. The symmetrical distribution can achieve an aesthetic effect without creating an abrupt visual effect. The distribution of multiple coil water cable connectors and coil water pipe connectors can effectively ensure the control of water flow rate and prevent the induction coil from being unusable due to blockage of a single connector.

[0023] Specifically, the coil water cable connector 20 is connected to both ends of the induction coil body 1 through a water pipe 100 , and being connected to both ends of the induction coil can ensure uniform heating of the induction coil and ensure that the temperature at each position of the induction coil is consistent.

[0024] Specifically, insulating plates of uniform size and thickness are provided between the induction coil bodies 1. The insulating plates can prevent the gap between the effective coils from narrowing, causing the voltage level to increase, thereby easily causing ignition, thereby increasing the voltage level and reducing energy consumption.

[0025] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
