Abstract
The utility model relates to an electric heater unit in the process of aluminum cell lining construction, using in the process of aluminum cell lining construction, and characterized in that the electric heater unit comprises a U-shaped electrical heating pipe, the U-shaped electrical heating pipe comprises an heating wire and a stainless steel outer tube, electrical insulating material is arranged between the electric-heat wire and the stainless steel outer tube, two ends of the heating wire are respectively connected with a connecting terminal. The electric heater unit has the advantages of simple and rational structure, great integrity, higher capability of power generation, and meeting the need of application, moreover meeting the construction requirements only with an electrical heating pipe of a power of 6 KW arranged at the center joint of a piece of carbon block, and very convenient for installment, application, debugging and maintenance. Protected by the stainless steel outer tube, the electric heater unit has the advantages of less damage, less maintaining quantity, low cost and easy operation, and safe property guaranteed by the electrical insulating material. Moreover as for the U-shaped electrical heating pipe is uniformly arranged in the slit of the carbon block, not only with the heat radiation heating of the heating pipe but also with air heating, the electric heater unit heats uniformly and deeply with high heat utilization efficiency, thereby improving heating effect and construction quality of the electrolysis bath.
Description
Technical field
The utility model relates to the electric heater unit in a kind of improved internal lining of aluminium electrolytic bath construction, is used in the internal lining of aluminium electrolytic bath construction process.
Background technology
In the internal lining of aluminium electrolytic bath construction, pricking paste of the solid end is one critical process, and the fine or not direct relation of its quality bath life, therefore creates good execution conditions for pricking solid work, and the cathode carbon pieces heating is exactly important behave wherein.
Charcoal piece heating means have multiple, the earliest be at sole piece upper berth one deck iron sheet, combustiblematerials such as burning firewood etc. on iron sheet, the advantage of this method is that one-time investment is few, upkeep cost is almost nil, but shortcoming is to want prepurging behind the firewood combustion, environment is poor, and labour intensity is big, and heat utilization ratio is low, and cathode carbon pieces upper and lower part, the back temperature difference of heating is big, influences construction quality.For this reason, did fuel flame heating method with Sweet natural gas and liquefied petroleum gas (LPG) afterwards, but still exist construction environment poor, labour intensity is big, heating also can only be heated on the cathode blocks surface, and charcoal interblock seam bottom charcoal piece is difficult for heating, causes the heating of charcoal piece inhomogeneous, cold in the promptly outer heat, after causing bundle solid, paste is inconsistent with expanding with heat and contract with cold of charcoal piece, thereby influences construction quality, and then have influence on work-ing life of electrolyzer, cause short-lived groove.In using the clean fuel process instead, also have and adopt electric stove wire or infrared heating plate, because electric stove wire is directly put into the charcoal piece centre joint and side seam, can't implement insulation measures, unsafe factors such as electricity take place to connect easily, and heat inhomogeneously, produce charcoal piece local phenomenon; Adopt the infrared heating plate, though heats can reach requirement, but the hot-plate quantity of using is more, and a seam needs 30 polyliths just can meet the demands approximately, and an electrolyzer heating uses this hot-plate to need the hundreds of piece, installation, wiring, dismounting workload are big, and hot-plate is fragile, causes maintain and replace frequent, causes difficulty to construction, thereby cause executive cost to raise, increase construction cost.
Summary of the invention
The purpose of this utility model is to provide the electric heater unit in a kind of improved internal lining of aluminium electrolytic bath construction, and is simple and reasonable, dependable performance, and it is convenient to use, and is beneficial to and increases work efficiency and construction quality, reduces production costs.
Electric heater unit in the internal lining of aluminium electrolytic bath construction described in the utility model, it is characterized in that being designed to the U-shaped electric heating tube, the U-shaped electric heating tube is made of nichrome wire and stainless steel outer tube, is lined with insulating material between nichrome wire and stainless steel outer tube, and the two ends of nichrome wire connect connection terminal respectively.
The utility model U-shaped electric heating tube, simple and reasonable, globality is strong, the power that can do is bigger, satisfy application requiring, article one, the charcoal piece centre joint only needs just can satisfy construction requirement by the electric heating tube that to adorn a power be 6KW, a 200KA electrolyzer, only 23 of need are just passable, installation, application, debugging and maintenance are all very convenient, especially can be the connecting plug of 26 connection terminals of 23 nichrome wire, and the directly supporting socket that is inserted into outside the groove, wiring connects more convenient, is beneficial to and increases work efficiency and construction quality.Protected by the stainless steel outer tube, not fragile, maintenance capacity is few, and cost is low, processing ease, and insulating material has guaranteed safety performance.And because of the U-shaped heating tube is to place charcoal piece slit uniformly, existing heating tube heat radiation heating is free hot air heating heat again, and homogeneous heating has the degree of depth again, and the heat utilization efficiency height has improved heats, has improved the construction quality of electrolyzer.
Description of drawings
Fig. 1, the utility model one example structure synoptic diagram.
Enlarged diagram is analysed and observe by A portion among Fig. 2, Fig. 1.
Among the figure: 1, U-shaped electric heating tube 2, connection terminal 3, stainless steel outer tube 4, nichrome wire 5, insulating material.
Embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, electric heater unit in the internal lining of aluminium electrolytic bath construction described in the utility model, be designed to U-shaped electric heating tube 1, U-shaped electric heating tube 1 is made of nichrome wire 4 and stainless steel outer tube 3, be lined with insulating material 5 between nichrome wire 4 and the stainless steel outer tube 3, the two ends of nichrome wire 4 connect connection terminal respectively.
After installing, directly the energising heating gets final product.
