The purpose of this utility model is that a kind of installation and maintenance that provide for fear of the deficiencies in the prior art are convenient, and volume is little, less energy consumption, efficient height, long chemical gases electric furnace of life-span.
The purpose of this utility model is achieved in that this stove is made up of body of heater shell, shell heat-insulation layer, furnace core body, gas interface, and its furnace core body is made up of seal cover, metal tank bracket, partiting thermal insulation supporting component, heating wire, binding post:
The partiting thermal insulation supporting component is fired on the outer wall by the double threaded screw of wearing in the hollow tubing conductor of equidistant groove and the endoporus by refractory material to be formed; The partiting thermal insulation supporting component is fixed on the metal tank bracket that has the hole on the two side then; With the heating wire of spirality coiling be suspended on the hollow tubing conductor outer wall equidistant groove in, the centre grips with the partiting thermal insulation supporting component again;
The high-alumina refractory brick burning process is adopted in the shaping of hollow tubing conductor, and double threaded screw is made with stainless steel, and heating wire is selected Aludirome silk or nichrome wire for use, and the line warp is greater than 4mm, and line length is greater than 45m, and the center distance of electric furnace heating wire is 25-30mm during coiling.
Laterally have the hole that 3-6 row installs the insulation supporting component on the two side of metal tank bracket, descending round most is oval, all the other Kong Weiyuan shapes, and upper and lower every row is 6 holes, and pitch of holes is 150-160mm, and middle every row is 11 holes, and pitch of holes is 74-84mm.
The utility model compared with prior art has following advantage:
1, owing to increased the supporting construction of heating wire, make the increase in density of laying heating wire, the electrical power caloric value that obtains in the unit volume strengthens.
2, heating wire is arranged in the heating furnace center, has dwindled the volume of heating furnace.
3, owing to adopt the partiting thermal insulation supporting component, it is good to make monoblock type, detachable, interchangeability to the electrothermal furnace core body, is convenient to maintenance and installation.
4, utilize the chemical property of Aludirome silk or nichrome wire, reduced the investment that other electric furnace heating wire adds protective layer in addition.
The drawing of the utility model chemical gases electric furnace is described as follows:
Fig. 1 is a chemical gases electrothermal furnace furnace binding schematic diagram.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is a chemical gases electric furnace furnace core body structural representation.
