Abstract

The utility model discloses a electrode coolant mechanism, comprising a electrode, a water jacket with baffles crossly provided in, a water inlet and a water outlet, wherein the width of the water jacket is bigger than the length of the baffles, whose height is equal to the distance between the inner and outer wall of the water jacket, and adjacent baffles whose three sides are fixed on walls of the water jacket are arranged at different sides of the walls of the water jacket. This electrode coolant mechanism, which prolongs the waterway and makes even distribution of current in the water jacket, greatly improves the cooling effect because of much energy taken by the current.

Description

The electrode cooling device of high temperature furnace

Technical field

The utility model relates to a kind of electrode cooling device, particularly a kind of electrode cooling device of high temperature furnace.

Background technology

Now, many industries such as metallurgy, chemical industry, electronics all will be used high temperature furnace, as are used under hydrogen shield the carbonization of niobium powder or the high-temperature heat treatment process of other materials.Temperature is generally all about 2200 degrees centigrade in this high temperature furnace, stove of high temperature like this, and its heater is made by graphite, and temperature homogeneity is good.There is electrode at the graphite heater two ends, electrodes exposed outside, Yin Gaowen stove heat radiation makes environment temperature very high, the easy oxidation of electrode, and electrode is difficult for lead-in wire, the foreskin of lead-in wire is also easily burnt.How the temperature of heater two end electrodes being lowered, is exactly crucial problem.

Common electrode cooling device is a water jacket, i.e. an end water flowing, and other end water outlet is taken away heat by the water circulation.Water jacket has certain width, during from current direction delivery port that water inlet is entered, has some dead angles, and current can't pass through, and current each position in water jacket is inhomogeneous.Because electrode is little, the water route is very short, and the time that water flows through is very short, and the heat of taking away is few, so cooling effectiveness is low.

The utility model content

Technical problem to be solved in the utility model provides a kind of electrode cooling device of high temperature furnace, makes the cooling effect of electrode at furnace heater two ends improve greatly.

For solving the problems of the technologies described above, the utility model has improved the water route in the water jacket, makes it distance and increases, and does not produce the dead angle.Whole device comprises electrode body, water jacket, water inlet, delivery port, the also staggered dividing plate that is equipped with in water jacket, dividing plate length be less than the water jacket width, and distance equates between height and water jacket inside and outside wall, dividing plate three faces are contained on the water jacket wall, and adjacent dividing plate is contained in the not homonymy of water jacket wall.

Water jacket is enclosed within the graphite heater two ends, cooperatively interacts between water jacket and the graphite heater, connects the awl sealing with graphite, compresses with hold-down ring in the outside.

After the improvement, will be moving from the current that water inlet enters at water jacket introversion baffling, flow to the other end from water jacket one end, spiral and advance, make interior each position of water jacket that the current process all be arranged, to flow out from delivery port again, the water route prolongs, and the heat of taking away is many, and cooling effect improves greatly.

The specific embodiment

High temperature furnace is a cylinder, is made up of graphite heater 4, in outside, heater 4 two ends the electrode cooling device is housed, and Fig. 1 is the partial cross sectional view that the high temperature furnace of the utility model electrode cooling device is housed, i.e. an end cutaway view.At the graphite heater 4 outside cooling water covers 8 of installing, water jacket 8 is connected awl 3 with 4 of graphite heaters with graphite and seals, and connects the awl 3 one ends outside and compresses with hold-down ring 2.This electrode cooling device comprises electrode body 1, water jacket 8, water inlet 5, delivery port 6, the staggered dividing plate 7 that is equipped with in water jacket 8, dividing plate 7 length are less than water jacket 8 width, the height with water jacket 8 inside and outside walls between the distance equate, dividing plate 7 three faces are contained on water jacket 8 walls, and adjacent dividing plate 7 is contained in the not homonymy of water jacket 8 walls.

Fig. 2 is the cutaway view of electrode cooling device among Fig. 1 along the A-A line.Can find out between water jacket inwall 9 and water-jacket outer wall 10 has dividing plate 7, to change the direction of a stream of water.

After the improvement, will be moving from the current that water inlet 5 enters at water jacket 8 introversion bafflings, flow to the other end from water jacket 8 one ends, spiral and advance, make water jacket 8 interior each positions that the current process all be arranged, flow out from delivery port 6 again.As shown in Figure 3, Fig. 3 is the sectional stretch-out view of Fig. 2 along the A-B-O-B-A line.In the whole water jacket 8 many dividing plates 7 are housed, the water route is prolonged, and current are evenly distributed in water jacket 8, thereby the heat of taking away is many, cooling effect improves greatly.
