Abstract
The utility model discloses a corrosion-resistant electric heater device, wherein, an electric heating element (6) is connected with a fixed clapboard (11), and the fixed clapboard (11) is connected with an insulating tube (4), with a knighthead (9) inside; a component is arranged in a radiant tube (7), which comprises the connection of the electric heating element (6), the fixed clapboard (11) and the insulating tube (4), as well as the knighthead (9), both ends of which are connected with a flange (1), and the flange (1) is connected with the flange of the radiant tube (7); one end of the conductive rod (10) is connected with a tail wire of the electric heating element (6), and the other end is connected with a connecting bus bar (2). The utility model is used in the electrolytic melting furnace, and can solve the problems of short period of usage and difficult replacement.
Description
Technical field
The utility model relates to a kind of electric heater unit.
Background technology
Electric heater unit is a heating plant crucial in " electrolyte melting stove ", and its major function is to provide required electrical heat energy to the electrolyte melting stove.The electrolyte melting stove of introducing is different from domestic existing " aluminium holding furnace " and " maintenance stove " and other alloying furnaces.The distinguishing feature of this electrolyte melting stove is: (1) furnace temperature height, drop temperature are 900 ℃ (aluminium cell requirements); (2) tilt bed (different fully) with fixed operation, the function complexity; (3) hydrogen fluoride corrosion that produces of fusing such as fluoride (aluminum fluoride, calcirm-fluoride, barium fluoride, sodium fluoride) is strong, makes general electric heating element be unable to undergo corrosion, and can only use just needed to change in several days.Just because of this, the electric heater unit of the existing stove of domestic aluminium industry is higher than in furnace temperature under 800 ℃ the situation, and its useful life is short, changes difficulty, and the higher situation of cost can't satisfy the requirement of electrolyte melting stove.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of novel corrosion resistant electric heater unit, to overcome the deficiency that useful life is short, change difficulty.
The utility model is to constitute like this: it comprises electric heating element (6), and electric heating element (6) is connected with stationary barrier (11), and stationary barrier (11) is connected with insulated tube (4), and support bar (9) is arranged in insulated tube (4); The assembly that electric heating element (6), stationary barrier (11), insulated tube (4) and support bar (9) constitute is placed in the radiant tube (7), and the two ends of support bar (9) are connected with flange (1), and flange (1) is connected with the flange of radiant tube (7); Lift one's head with electric heating element (6) and be connected in conducting rod (10) one terminations, another termination is connected with connection bus (2).
Support bar (9) is connected with insulated tube (4) by hold-down nut (5).
One end of support bar (9) pass flange (1) and with its welding, the other end passes flange (1) and connects by insulating washer (3) and nut.
Packing ring (8) is arranged between the flange of flange (1) and radiant tube (7).
The quantity of stationary barrier (11) is decided according to the length of electric heating element (6).
The utility model mainly contains following advantage: (1) adopts the telescopic method of radiation to completely cut off the corrosion of the interior hydrogen fluoride gas of stove to electric heating element, makes its life-span purpose that has reached protection and prolonged electric heating element, has reduced production cost.Radiant tube is made with alloys such as high temperature resistant stainless steels, radiation effect and useful life are all fine, it is short that a main outstanding difficult problem in the production in electrolyte melting stove past is exactly the electric heating element life-span, now adopts the radiation sleeve pipe to make electric heating element select for use the general nichrome life-span also very long; (2) electric heating element is changed conveniently, as long as connection and set bolt are just unloaded and can be changed the whole extraction of electric heating element; (3) stationary barrier (11) is fixed the electric heating element of cross-under, and resembling when electric heating element can be because of hot mastication yet when stove is tumbled discharging slides the resistance wire causes the harm of overlapping short circuit.(4) this device is novel in design, and economic benefit obviously improves, and is worthy to be popularized.
