Abstract
The utility model relates to a nitrogen heating furnace, in particular to a new energy improvement device in the nitrogen heating furnace. The technical scheme is that: the new energy improvement device mainly comprises a heating resistance wire, a furnace body, a nitrogen heating coil pipe, a gas outlet and a gas inlet; the nitrogen heating coil pipe is arranged in the center of an inner cavity of the furnace body; the heating resistance wire is wound on the inner wall of the furnace body and connected with a power supply; and the gas outlet and the gas inlet are formed in the top of the furnace body and communicated with two ends of the nitrogen heating coil pipe respectively. The new energy improvement device in the nitrogen heating furnace has the beneficial effects that: temperature of nitrogen is controlled by electric heating, so that energy can be saved, the production cost is reduced, and stable supply of nitrogen under the condition of increasing the temperature of the nitrogen can be guaranteed; and therefore, the yield of aluminum powder is increased, and the yield of fine powder is increased greatly.
Description
Technical field:
The utility model relates to a kind of nitrogen heating furnace, new forms of energy device for modifying in particularly a kind of nitrogen heating furnace.
Background technology:
The production of aluminum powder device is to be raw material with the aluminium ingot, utilizes HTHP nitrogen through behind the atomizer, forms vacuum at jet hole, and promptly Venruri (venturi) phenomenon is extracted aluminium liquid and smash out by the nozzle of atomizer, and the cooling back generates aluminium powder.Wherein, oxidized in order to prevent aluminium powder in heat, two kinds of methods are arranged usually, the one, can inflated with nitrogen; The 2nd, heating in vacuum; Wherein industry method upward commonly used is an inflated with nitrogen; And nitrogen need be heated to the condition of high temperature in the nitrogen heating furnace before getting into molten aluminium furnace apparatus; Existing nitrogen heating furnace is to adopt petroleum product to act as a fuel to heat, and the problem of its existence is: the one, burnt out coil pipe through regular meeting, then; Shut down maintenance, influence production work; The 2nd, the efficiency of heating surface is low, and it is bigger to consume energy, the waste petroleum resources.
Summary of the invention:
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and new forms of energy device for modifying in a kind of nitrogen heating furnace is provided.
Its technical scheme is: mainly be made up of resistive heater, body of heater, nitrogen heat(ing) coil, gas outlet, air inlet, described body of heater lumen centers is provided with the nitrogen heat(ing) coil, coils resistive heater on the inwall of body of heater, and resistive heater is connected with power supply; The top of described body of heater is provided with gas outlet and air inlet, is communicated with the two ends of nitrogen heat(ing) coil respectively.
Above-mentioned resistive heater is connected with power supply through frequency-variable controller.
The beneficial effect of the utility model is: through the temperature of electrical heating control nitrogen; Not only can save the energy, reduce production costs, and can guarantee to improve the stable supply of nitrogen temperature; And then the output of aluminium powder is got a promotion, the yield of fine powder also significantly improves.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: resistive heater 1, body of heater 2, nitrogen heat(ing) coil 3, gas outlet 4, air inlet 5, frequency-variable controller 6.
The specific embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of resistive heater 1, body of heater 2, nitrogen heat(ing) coil 3, gas outlet 4, air inlet 5; Described body of heater 2 lumen centers are provided with nitrogen heat(ing) coil 3; Coiling resistive heater 1 on the inwall of body of heater 2, resistive heater 1 is connected with power supply; The top of described body of heater 2 is provided with gas outlet 4 and air inlet 5, is communicated with the two ends of nitrogen heat(ing) coil 3 respectively; Above-mentioned resistive heater 1 is connected with power supply through frequency-variable controller 6.
During use, through the temperature in the frequency-variable controller 6 control bodies of heater, energy-saving effect is remarkable; Nitrogen gets into nitrogen heat(ing) coil 3 through air inlet, then, discharges through the gas outlet, utilizes HTHP nitrogen through behind the atomizer, forms vacuum at jet hole, and aluminium liquid is extracted out and smashed by the nozzle of atomizer, and the cooling back generates aluminium powder.
