Abstract
The utility model provides a nickel electrode with low cost used in a platinum tube for replacing a platinum electrode, which comprises a platinum ring, a nickel electrode ring arranged around the platinum ring and a nickel electrode plate connected on the nickel electrode ring. The utility model uses the nickel electrode as a heating electrode, as the cost of nickel is lower than the cost of platinum, thus leading the cost of the utility model to be low; besides, the nickel electrode is cooled by a cooling tube in the utility model, which reduces the damage to platinum caused by nickel.
Description
Technical field
The utility model relates to the production field of optical glass, particularly relates to a kind ofly replacing the nickel electrode that platinum is switched on the platinum pipe as electrode.
Background technology
Adopt the pipeline of platinum pipe at the optical glass production field as the glass circulation, directly energising on the platinum pipe, thus the platinum pipe produces heat to the glass metal heating as resistance, obtains the glass metal of constant viscosity.And the present common platinum electrode that adopts platinum ring and platinum plate to constitute is switched on to the platinum pipe, but along with the continuous of platinum price risen, the cost of platinum electrode is more and more higher.
The utility model content
Technical problem to be solved in the utility model provides a kind of nickel electrode that is used for the platinum pipe that can replace platinum electrode cheaply.
The technical scheme that the utility model technical solution problem is adopted is: be used for the nickel electrode of platinum pipe, comprise the platinum ring, be provided with the nickel electrode ring around described platinum ring, be connected with the nickel electrode plate on described nickel electrode ring.
The beneficial effects of the utility model are: adopt nickel electrode as heating electrode, the cost of nickel is lower than the cost of platinum, and therefore cost of the present utility model is low; In addition, the utility model cools off nickel electrode by cooling water pipe, has reduced the infringement of nickel to platinum.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, the utility model is that nickel electrode ring 2 is set on platinum ring 5, and nickel electrode ring 2 is connected with nickel electrode plate 1 around platinum ring 5 on the nickel electrode ring 2.
In use, platinum ring 5 is installed around platinum pipe 6, as shown in Figure 3 and Figure 4, and the external diameter of the internal diameter of platinum ring 5 and platinum pipe 6 coupling.
Nickel is at high temperature harmful to platinum, in order to reduce nickel electrode ring 2 at high temperature to the erosion and the infringement of platinum ring 5, on nickel electrode ring 2 and nickel electrode plate 1, cooling water pipe 4 is set preferably, as shown in Figure 3, cooling water pipe 4 is around nickel electrode ring 2 and nickel electrode plate 1, be connected with refrigerating gas or liquid at cooling water pipe 4, but logical cooling water cost is minimum, cooling water pipe 4 can be made of copper.
The design principle of the thickness of nickel electrode plate 1 of the present utility model, nickel electrode ring 2 is as follows:
According to Ohm's law R=U/I, as can be seen, in the time of guaranteeing to use platinum electrode and use nickel electrode of the present utility model, electric current and voltage constant, resistance must equate, that is to say that the resistance of platinum electrode and nickel electrode must equate; Again according to the formula R=PL/S that concerns between resistance and the resistivity, as can be seen, resistivity and sectional area are inversely proportional to, and can draw according to the resistivity of platinum and nickel: the thickness of nickel electrode plate 1 of the present utility model, nickel electrode ring 2 be platinum ring 5 thickness 3-7 doubly.
In order to make the connection between platinum ring 5 and the nickel electrode ring 2 tightr, be preferably in an annular groove is set on the nickel electrode ring 2, be embedded in the annular groove platinum ring 5 and welding, as shown in Figure 4 and Figure 5.
The utility model is in specific implementation process, and the thickness of platinum pipe 6 is 0.6-0.8mm, and diameter is φ 120-140; The thickness of platinum ring 5 is 1.5-2.5mm, and internal diameter is φ 120-140, and external diameter is φ 190-210; The thickness of nickel electrode ring 2 is 8-10mm, and internal diameter is φ 190-210, and external diameter is φ 210-230; The thickness of nickel electrode plate 1 is 8-10mm, and wide is 90-110mm; The internal diameter of cooling water pipe 4 is φ 10-12, and thickness is 1.0-2mm.
