Abstract
The utility model relates to an electric roasting apparatus for diatomite filter aid, which belongs to a chemical engineering mechanical class. The electric roasting apparatus uses a rotary drive mechanism of a common horizontal rotary kiln. The electric roasting apparatus is characterized in that a high-aluminum light weight heat-insulating layer, a refractory masonry layer of electrothermal tube bundle cavities which are evenly distributed, and electrothermal tube bundles arranged inside the electrothermal tube bundle cavities are arranged inside a kiln body; one end of the kiln body is provided with a slip-ring electric input device, and the end surface of the feeding end of a roasting chamber is provided with a stainless steel chain. The utility model produces filter aid under a dynamic state in an electric roasting mode, and thus the physical structure of products changes uniformly under high temperature without any contamination, and the utility model not only ensures quality but also reduces cost.
Description
The utility model is a super-cell electricity roasting apparatus, belongs to the chemical machinery class.
At present, the main production equipments of emerging filter medium one super-cell of domestic filtration art is used coal always, heavy oil, the route that acts as a fuel such as diesel oil directly contacts roasting with product, the problem that exists is: the filter aid product is subjected to carbon distribution to some extent and does not fire or the pollution of harmful substance, Yunnan head exclusively uses static electric roasting apparatus at home, changes problems such as inhomogeneous but exist filter aid physical arrangement in roasting process.
The purpose of this utility model is: provide a kind of dynamic rotation electricity roasting apparatus to solve the deficiency of above-mentioned technology, guarantee the product uniformity that physical arrangement changes under the condition of high temperature, can avoid filter aid in roasting process, directly to contact again, promptly ensure the quality of products and reduce cost with fuel.
The utility model is to realize on horizontal revolving kiln basis in the past; concrete structure is: the kiln body is a garden shape metal shell; the transmission mechanism that housing has the rotating support support roller outward and impels the kiln body to rotate; transmission mechanism comprises motor; the all gears in outer garden on driven wheel and the kiln body; near outer wall in the kiln body is the high-alumina lightening heat-insulation layer; be that refractory brick is built layer by laying bricks or stones then; build by laying bricks or stones and leave equally distributed electric heating tube bank chamber in the layer; the electric heating tube bank is installed in the chamber; (resistance wire or other heating) its power supply is connected in the input of electric slip ring distribution and seal of kiln body terminal; building layer by laying bricks or stones inboard is coat of metal; the protective layer inboard is the firing chamber; peace one stainless steel stirs chain on the end face of firing chamber's feed end; the course of work of the present utility model is; send behind the device start; when reach be suitable for temperature that filter aid feeds intake after; send into confected materials in the hopper of kiln hood by conveying worm; pursuing ashamed entering in the firing chamber by hopper, because rotary kiln is to tilt to install, material constantly stirs in the kiln body and has chain to stir; by giving heat; in the stage of roasting, the semi-finished product that are filter aid that the kiln tail goes out have been finished main calcining process.
Good effect of the present utility model is: can guarantee the uniformity that the filter aid physical arrangement changes, avoid filter aid in roasting process, directly to contact again, do not have pollution problem, overcome raw material moisture content height again and product " extension kiln " problem of generation with fuel, promptly ensure the quality of products, reduce cost again.
Be the correction data of fuel oil roasting and dynamic electric roasting below.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cut-away view of the present utility model.
Wherein: 1 kiln body case, 2 supporting support rollers, 3 rotating mechanisms, 4 high-alumina lightening heat-insulation layers, 5 refractory brick are built layer by laying bricks or stones, the tube bank of 6 electric heating, 7 slip rings electricity input unit, 8 metal heat-conducting protective layers, 9 stir chain, 10 firing chambers.
Specific embodiments of the present utility model is: get the 3mm steel plate and make long 10 meters; diameter is 1.2 meters a garden shape kiln body 1; the rotary drive mechanism of the common horizontal revolving kiln of the external employing of kiln; comprising two rotating support support rollers 2 and the transmission mechanism 3 that impels the kiln body to rotate; build the high-alumina lightening heat-insulation layer 4 that thick 200mm is arranged near outer wall in the kiln body; be that 250mm refractory brick is built layer 5 by laying bricks or stones then; build by laying bricks or stones and leave equally distributed 18 electric heating tube bank chamber in the layer; electric heating tube bank 6 is installed in the chamber; its resistance wire is every 150KW of ∮ 4cm; take parallel circuit; power supply is connected in the input of electric slip ring distribution and seal 7 of rotary kiln body terminal; by what build layer inboard by laying bricks or stones is 10mm metal heat-conducting protective layer 8, and the protective layer inboard is firing chamber 10, and peace one stainless steel stirs chain 9 on the end face of firing chamber's feed end; the other end of chain is a free end; be positioned at discharge end, in addition the also available far ultrared paint of electric heating tube bank is coated with to tie up and can economizes on electricity 25%, more than just finished implementation process of the present utility model.The course of work is: send behind the device start, when reach be suitable for temperature that filter aid feeds intake after, raw material is sent in the firing chamber by conveying worm, because rotary kiln is a material that tilt to install constantly to be stirred in the kiln body and has chain to stir and tremble, by giving the stage of thermal bake-out, the semi-finished product that are filter aid that the kiln tail goes out have been finished main calcining process.
