Abstract
The utility model relates to an aluminium powder production auxiliary device, in particular to a temperature control system of a nitrogen heating furnace. The technical scheme is that the temperature control system of the nitrogen heating furnace comprises heating wires, a heating furnace body, a heating pipe coil, a nitrogen inlet pipe, a nitrogen outlet pipe and an electric heating controller. A circle of heating wires are arranged on the inner wall of the heating furnace body, and the heating wires are connected with the electric heating controller to control temperature. The heating pipe coil is fixedly arranged in a middle cavity of the heating furnace body, the upper end of the heating pipe coil is connected with the nitrogen inlet pipe, and the lower end of the heating pipe coil is connected with the nitrogen outlet pipe. The temperature control system of the nitrogen heating furnace has the advantages that the heating pipe coil is improved, the temperature of nitrogen is further controlled, not only can energy be further saved, production cost is lowered, but also stable supply of the temperature of the nitrogen can be guaranteed, so that the yield of aluminium powder is improved, and the yield of fine powder is also improved greatly.
Description
Technical field:
The utility model relates to a kind of production of aluminum powder servicing unit, particularly a kind of nitrogen heating furnace temperature control system.
Background technology:
The production of aluminum powder device is take aluminium ingot as raw material, utilizes HTHP nitrogen by behind the atomizer, forms vacuum at jet hole, and namely Venruri (venturi) phenomenon is extracted aluminium liquid and smash out by the nozzle of atomizer, generates aluminium powder after the cooling.Wherein, oxidized at high-temperature heating in order to prevent aluminium powder, two kinds of methods are arranged usually, the one, can inflated with nitrogen; The 2nd, heating in vacuum; Wherein industrial method commonly used is inflated with nitrogen, and nitrogen need to be heated to the condition of high temperature in nitrogen heating furnace before entering molten aluminium furnace apparatus, existing nitrogen heating furnace is to adopt petroleum product to act as a fuel to heat, the problem of its existence is: the one, often can be burned coil pipe, then, shut down maintenance, affect production work; The 2nd, the efficiency of heating surface is low, and it is larger to consume energy, the waste petroleum resources.China Patent No. is that 201120439229.7 patent documentation discloses a kind of " New energy improvement device in nitrogen heating furnace ", and it adopts electric-control method to realize heating, but because its coil arrangement causes efficient to also have the space that promotes.
Summary of the invention:
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of nitrogen heating furnace temperature control system is provided, and its efficiency of heating surface is higher, has more saved the energy.
Its technical scheme is: comprise heater strip, heating furnace body, heat(ing) coil, nitrogen air inlet pipe, nitrogen escape pipe, electrical heating controller, a circle heater strip is installed on the described heating furnace body inwall, heater strip connects electrical heating controller control temperature; The middle chamber of described heating furnace body is heat(ing) coil fixedly, and the upper end of heat(ing) coil connects the nitrogen air inlet pipe, and the lower end of heat(ing) coil connects the nitrogen escape pipe.
The beneficial effects of the utility model are: by improving heat(ing) coil, further control the temperature of nitrogen, not only can further save the energy, reduce production costs, and the stable supply that can guarantee to improve 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 structural representation of the present utility model;
Among the upper figure: heater strip 1, heating furnace body 2, heat(ing) coil 3, nitrogen air inlet pipe 4, nitrogen escape pipe 5, electrical heating controller 6.
The specific embodiment:
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises heater strip 1, heating furnace body 2, heat(ing) coil 3, nitrogen air inlet pipe 4, nitrogen escape pipe 5, electrical heating controller 6, and a circle heater strip 1 is installed on described heating furnace body 2 inwalls, and heater strip 1 connects electrical heating controller 6 control temperature; The middle chamber of described heating furnace body 2 is heat(ing) coil 3 fixedly, and the upper end of heat(ing) coil 3 connects nitrogen air inlet pipe 4, and the lower end of heat(ing) coil 3 connects nitrogen escape pipe 5; The outer wall of heat(ing) coil 3 is near the heater strip 1 on the inwall.
Certainly, also heater strip 1 directly can be wrapped in the periphery of heat(ing) coil 3, to realize better heating effect.
The utility model has improved the shape of heat(ing) coil, by the temperature in the electrical heating controller 6 control bodies of heater, and then realization is to effective heating of nitrogen, not only can further save the energy, reduce production costs, and the stable supply that can guarantee to improve nitrogen temperature, and then the output of aluminium powder is got a promotion, the yield of fine powder also significantly improves.
