Abstract
The utility model relates to a nitriding furnace, especially a cooling device of nitriding furnace cooling zone, this nitriding furnace cooling device, including the nitriding furnace and installing the cooling device on the disc outside the nitriding furnace cooling zone, the above -mentioned cooling device of its characterized in that is that the coil set on the disc becomes outside the nitriding furnace cooling zone by fixing, and the coil pipe water inlet links to each other with water installations, and a delivery port and a water installation of coil pipe are continuous. The technical scheme of the utility model the cooling water velocity of flow very fast, the caloric receptivity is big, and is more convenient to the processing of incrustation scale. And have characteristics such as rational in infrastructure, that the cooling effect is good, be applicable to very much the cooling of various furnace bodys.
Description
Art
The utility model relates to a kind of nitriding furnace, particularly a kind of refrigerating unit of nitriding furnace cooling section.
Background technology
No matter be sedimentation nitriding furnace or revolution nitriding furnace in current nitriding furnace, the periphery of its cooling section be all provided with cooling water chuck and cool in stove, to reduce drop temperature.Because the temperature when furnace charge in nitriding furnace enters cooling section is about more than 900 DEG C, this absorption with regard to needing a large amount of water coolants to carry out heat.And in the process that passes in and out at current of this type of cooling of water jacket, dead angle can be produced in chuck, make cooling section furnace body temperature uneven on the one hand, cooling section body of heater is caused to be out of shape and reduction in work-ing life, on the other hand because the flow velocity of water coolant in water jacket is uneven, the water coolant causing flow velocity slower forms cooling dead angle in water jacket, when after the water coolant water vapor in cooling dead angle, the pressure in water jacket will be caused to raise rapidly, water jacket is burst, light then the water inlet pipe and water outlet pipe of nitriding furnace water coolant is collapsed out, heavy then nitriding furnace cooling section cooling jacket is out of shape, chuck more seriously can be made to break, the generation that will set off an explosion once water coolant and furnace charge meet.Manufacturer is just had to bleed the example of accident of blasting in stove because of jacket water (J.W.) at home, simultaneously because the space in water jacket is comparatively large, comparatively difficult to the process of incrustation scale in it.
Summary of the invention
The purpose of this utility model overcomes the defect that prior art exists, and provides a kind of refrigerating unit of a kind of nitriding furnace cooling section of rational in infrastructure, good cooling results.
For achieving the above object, the technical solution of the utility model is: a kind of refrigerating unit of nitriding furnace cooling section, comprise nitriding furnace and be arranged on the refrigerating unit on nitriding furnace cooling section periphery, it is characterized in that above-mentioned refrigerating unit is made up of the coil pipe be fixed on nitriding furnace cooling section periphery, coil inlets is connected with water feed apparatus, and the water outlet of coil pipe is connected with discharging device.
Above-mentioned coil pipe is the close passage of spirrillum formed after semicircular semi-circular tube welds with nitriding furnace cooling section body of heater periphery by cross section.
The close passage of duplex shape that above-mentioned coil pipe is formed by two semi-circular tubes and nitriding furnace cooling section body of heater periphery forms.
The material of above-mentioned coil pipe is identical with the material of the body of heater periphery of nitriding furnace cooling section.
The technical solution of the utility model is the improvement to existing nitriding furnace cooling section water-cooling structure, it is the outer round surface that spiral tube by being semicircle is fixed on nitriding furnace cooling section by cross section, spiral helicine semicircle cooling channel is formed on its surface, such water coolant directly can absorb the heat on nitriding furnace cooling section surface, on the one hand because flow velocity is very fast, the heat that water coolant absorbs increases.Through measuring and calculating compared with the existing water jacket type of cooling, adopt the water coolant of identical amount, the temperature of cooling water outlet, by about 60 DEG C, is increased to about 80 DEG C; On the other hand due to the pipe spiral cooling channel of semicircle, water coolant by time flow velocity all use unanimously, to solve in current water leg structure because water coolant flow velocity is uneven, cause stream water coolant in water jacket, form the problem cooling dead angle; 3rd, the process of this structure to the incrustation scale of the pipe spiral cooling channel of semicircle is convenient.
In sum, the technical scheme of utility model has the features such as rational in infrastructure, good cooling results, is highly suitable for the cooling of various body of heater.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the I structure enlarged diagram of the utility model accompanying drawing 1.
Embodiment
As shown in Figure 1, 2, on the periphery of nitriding furnace cooling section 1, spirrillum is fixed with coil pipe 2, and the water-in 4 of coil pipe is connected with the water feed apparatus of existing nitriding furnace, and the water outlet 3 of coil pipe is connected with the discharging device of existing nitriding furnace.For increasing the amount of heat absorption of coil pipe inner cooling water, coil pipe is that the semi-circular tube be divided into two along its circular hollow section by the pipe that the body of heater Facing material with cooling section is identical is made, semi-circular tube being bent into spirrillum is welded on the body of heater periphery of nitriding furnace cooling section, Formation cross-section is the water coolant seal channel of semicircle, water coolant is entered by water-in, be that the spirrillum seal channel of semicircle rapidly flows through along cross section, discharged by water outlet, when water coolant flows through in the spirrillum seal channel of semicircle, heat exchange can be carried out with cooling section body of heater surface, the temperature of nitriding furnace cooling section is reduced rapidly, and its surface temperature is very all used, solve at present due to the water coolant vaporization problem that flow velocity inequality is formed in water jacket.
For better ensureing the cooling performance to nitriding furnace cooling section, the spiral pipe of semicircle shape can be two, duplex coil pipe is just defined like this at the outside surface of nitriding furnace cooling section, increasing is twice by the flow of water coolant, water coolant in the spiral pipe of semicircle shape in the residence time will reduce nearly half, the temperature in nitriding furnace cooling section so just can be made to reduce further.
The spiral pipe of semicircle shape selects identical material with cooling section body of heater periphery, its objective is that to make the spiral pipe of semicircle shape consistent with the shrinking percentage of cooling section periphery, prevent from causing coil pipe and generation crack, cooling section outer round surface face because cooling section body of heater expands with heat and contract with cold.
This device can be used for the cooling needs of the cooling section of sedimentation nitriding furnace and revolution nitriding furnace.
