Description
Technical Field
The invention relates to the technical field of barbecue equipment, in particular to a novel heating wire for food material processing.
Background
The heating wire is made of solid material, the oxidation resistance of the iron-chromium-aluminum and nickel-chromium electrothermal alloy is generally stronger, and the heating wire is processed into various shapes required by users. It has simple structure, high heat efficiency, high mechanical strength and excellent adaptability to harsh environment. It can be used for heating various liquids and acid, alkali and salt, and is also suitable for heating and melting metals with low melting point (lead, zinc, tin and babbitt metal), and is commonly used in industrial heating equipment and civil heating appliances of metallurgical machinery, medical treatment, chemical industry, ceramics, electronics, electrical appliances, glass and the like.
The prior art is with heater strip and interface terminal lug connection, can lead to the heater strip high temperature when the heater strip heats, can make the terminal temperature with heater strip lug connection uprise, and then can arouse the transformer temperature rising of being connected with the terminal, makes transformer equipment life short excessively.
Disclosure of Invention
The invention aims to solve the problem that the temperature of a transformer is increased due to the fact that a heating wire is directly connected with an interface terminal in the prior art, and provides a novel heating wire for food processing.
In order to achieve the purpose, the invention adopts the following technical scheme:
a novel heating wire for food processing comprises a heating wire, wherein connecting pipes are fixedly connected to the end parts of the two ends of the heating wire, the inner wall of each connecting pipe is closely attached to the outer wall of the end part of the heating wire, the connecting pipes are aligned with the end parts of the outer sides of the heating wire, annular welding connecting rings are welded to the end parts of the inner sides of the connecting pipes and the heating wire, and the connecting pipes and the heating wire are fixedly connected through the welding connecting rings; the connecting pipe is provided with a connecting terminal.
Preferably, the connecting pipe is made of copper metal.
Optionally, the ratio of the wall thickness to the length of the connecting pipe is 1: 15.
Optionally, the length of the connecting pipe is 15cm, and the wall thickness of the connecting pipe is 1 cm.
The beneficial effects of the invention are as follows:
through cup jointing of copper connecting pipe and heater strip, realize the contact of large tracts of land, make the area of conducting electricity increase, adopt copper metal to make, copper has the high melting point, and low resistance, the characteristics that electric conductivity is good, so the temperature is lower during the circular telegram, rethread connecting terminal external power supply, realize heater strip and connecting terminal indirect connection, the temperature that produces when the heater strip work is cooled down through the connecting pipe, contact with connecting terminal again, stop heater strip and connecting terminal direct contact messenger connecting terminal high temperature, cause the equipment damage of being connected with connecting terminal, the condition that equipment service life reduces takes place.
