Description
Technical field
The utility model relates to a kind of rotating electric furnace, and the inwall that specifically relates to a kind of continuous preparation plating-grade copper oxide does not have the fouling rotating electric furnace.
Background technology
Along with the continuous upgrading of electronic industry, electron trade is made PCB and has been proposed stricter requirement.The technology that tradition adopts copper coin to make positive plate and supplementation with copper source progressively is eliminated, and is replaced by horizontal electroplating technology, but the quality of cupric oxide has been proposed requirements at the higher level.The most of producer of existing plating-grade copper oxide adopts pushed bat kiln calciner calcining ventilation breather to prepare plating-grade copper oxide, there is following problem in this method: (1) is because of the kiln temperature skewness, the reaction mass rerum natura is also even inadequately, low temperature part ventilation breather is not grilled thoroughly and is contained quantity not sufficient, and the high-temperature part cupric oxide has been burnt to death, loses activity; (2) the charging saggar falls slag and brings polluted products such as material impurity silicon, aluminium, calcium into, makes the requirement that can't touch the mark of the Chemical Composition of plating-grade copper oxide; (3) because material is fixed bed, temperature distributing disproportionation is even, make the production time long, energy consumption is high; (4) manual operations, labour intensity is big, can not realize automatization.
To sum up, the helicoid electric furnace of existing calcining usefulness is owing to exist degree of heat abundant inadequately, and heating or constant temperature time are inhomogeneous, and material only relies on action of gravity to move, and is bonded at the furnace wall easily, causes problems such as material burning, spillage of material, product quality defect.
Summary of the invention
The utility model has overcome traditional pushed bat kiln and calcining with the shortcoming of rotary type electric furnace, provides a kind of inwall that heats the continuous preparation plating-grade copper oxide controlled, that material moves evenly, the furnace wall material bonds less, quality and recovery rate are high not have the fouling rotating electric furnace.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of inwall of continuous preparation plating-grade copper oxide does not have the fouling rotating electric furnace, comprises stove tube, preceding supporting-point roller, electrical heat tracing burner hearth, back supporting-point roller, and described furnace tube outer wall is provided with at least one stove tube percussion device.
Described stove tube percussion device comprises hollow cavity and spheroid, and hollow cavity one end is fixed on the furnace tube outer wall, and the spheroid activity is located in the hollow cavity and with the stove tube and is the gap crash situation.
Described hollow cavity is vertically installed in furnace tube outer wall.
Described hollow cavity is polyhedral, cylindric or cage shape.
After adopting technique scheme, the beneficial effect that the utility model reaches is:
(1) adopt rotating electric furnace to replace the pushed bat kiln in the former technology to calcine ventilation breather, uniformity of temperature profile in the electric furnace, the reaction mass rerum natura is even, heating or constant temperature time are controlled, avoid in original technology low temperature part ventilation breather not grill thoroughly and contained quantity not sufficient, and the high-temperature part cupric oxide has been burnt to death, deactivated phenomenon, guaranteed that raw material is not contaminated in the charging process, the Chemical Composition of plating-grade copper oxide is met the demands, shortened the production time, reduced production energy consumption, realize the mechanized of calcining, reduced labour intensity.
(2) according to the heavy characteristics of ventilation breather, stove tube outside stack shell adopts percussion device, bump by spheroid in the percussion device and stove tube stack shell, the material that remains in stove tube inwall is shaken fully from stove tube inwall, move to discharge end with material, avoided the part ventilation breather to be bonded at cold zone and burnt not thoroughly, partial oxidation copper is bonded at the high-temperature zone burning and deactivated phenomenon, has improved quality and the recovery rate of cupric oxide.
