The purpose of this utility model is to realize like this
A kind of electrical heating revolving drum roaster mainly is to be made of feed box, stove tube, material feeding box, transmission system, support roller shelves wheels, support roller group, temp measuring system.The stove tube passes across burner hearth, adopts the high-temperature sealing material sealing between burner hearth and stove tube, embeds pressing plate, makes encapsulant be close to hearth wall; In the stove tube temp measuring system is housed, is fixed together with feed box, inboard wall of burner hearth lays high-temperature refractory, and burner hearth bottom is equipped with electric furnace heating wire, and burner hearth adopts split type; There are feed box and material feeding box in two ends, the stove tube left and right sides, and feed box sealing and feed end sealing are arranged between feed box and material feeding box and stove tube, and support roller group and the separation of support roller shelves wheels are in the both sides of burner hearth.
The high-temperature material that described burner hearth inside is laid is burner hearth bottom and adopts the multiple layer refractory brick, and sidewall and loam cake adopt the high-temperature refractory fiber module.The spirality electric furnace heating wire of burner hearth bottom is enclosed within putting on the fiber tube that refractory material makes.Put on the fire-resistant silk tweel block that fiber tube is installed in burner hearth bottom.On burner hearth sidewall, put the fiber tube corresponding position and be provided with electric furnace heating wire maintenance window.
Described temp measuring system is to be made of thermometric cover support, temperature-measuring casing, sliding bearing.Temperature tube support and stove tube are fixed together, and there is sliding bearing temperature tube support junction, and temperature element inserts in the stove tube by temperature tube.
Temperature-measuring casing can be fixed together with material feeding box, also can be affixed with feed box.
The utility model compared with prior art, the characteristics that have and the beneficial effect of generation are
1, adopts the electrical heating burner hearth, utilize the mode of radiant heat transfer, when improving fire box temperature, can also simplify the burner hearth hermetically-sealed construction, avoided high-temperature gas simultaneously, prolong the life-span of burner hearth the washing away of inboard wall of burner hearth;
2, refractory brick is adopted in the bottom of burner hearth; Sidewall and loam cake adopt the high-temperature refractory fiber module, and this structure has alleviated the weight of burner hearth widely, and burner hearth adopts split-type structural, are convenient to install and transportation;
3, the utility model has designed rational hermetically-sealed construction, has strengthened the sealing effectiveness of burner hearth and stove tube widely, reduces the loss of electric energy, has improved efficient;
4, two groups of support rollers and one group of shelves wheel have been adopted in the support of stove tube, have avoided owing to the influence of high temperature to the equipment transmission stability and the reliability of the normal operation of assurance equipment effectively.
5, in the stove tube temp measuring system is housed, can monitors material temperature when operating in the stove tube at any time.
