Description
Technical field
The utility model relates to a kind of tilting rotary furnace that can introduce the multiple atmosphere that comprises hazardous gas.
Background technology
The preparation equipment of the drying of powder stocks such as carbide alloy, structural ceramics, function ceramics, cermet, thermal decomposition, calcining, oxidation, reduction, carbonization, nitridation process is normally:
(1) fixed bed: prepare in the powder process with this equipment, because raw material does not fully contact with reaction atmosphere, cause reacting inhomogeneous, remain static owing to powder simultaneously, powder is assembled easily in course of reaction and is grown up, and the product particle that obtains is thick, composition and size distribution are all even inadequately.
(2) fluid bed: this equipment has overcome the shortcoming of fixed bed, purposes is widely arranged in powder preparation, but owing to need a large amount of use reacting gas and carrier gas, cause the powder preparation cost to increase, the powder of flow regime is taken out of by gas easily simultaneously, and it is complicated to make the preparation productive rate reduce, control.
(3) rotary furnace: this equipment is widely used in a plurality of fields such as chemical industry, metallurgy, building materials, garbage disposal, as: scrap lead melting rotary furnace (Mei Jialin, Chinese utility model patent ZL 95 2 26707.1, November 27 nineteen ninety-five); The rotary furnace grate furnace of burning away the refuse (Li Xin, Chinese utility model patent ZL on December 19th, 00253487.8,2000); Electric heating rotary furnace for ferromagnetic materials (summer gravity, Chinese invention patent ZL 97 1 01681.X, on March 17th, 1997); Wet method aluminum fluoride external-heat dehydrates rotary furnace (Li Yingwei etc., Chinese utility model patent ZL on April 19th, 992 09446.1,1999); Magnetic material sintering external-heating rotary kiln (Chen Ruisheng, Chinese utility model patent ZL on August 1st, 89205257.9,1989); Rotary kiln with resistor furnace for heating and calcining kaolin (Feng Jianming etc., Chinese invention patent ZL 01128612.1, September 19 calendar year 2001); Multi-functional rotary kiln (in Xiang, Chinese utility model patent ZL on March 26th, 96231504.4,1996); Wind and water cooling rotary kiln (Han Shiguo, Chinese utility model patent ZL on August 24th, 91223886.0,1991); Efficient rotary kiln (Chen Gengyun, Chinese utility model patent ZL on November 18th, 98242686.0,1998); Outer heating rotary kiln (Yuan Yiming etc., Chinese utility model patent ZL on May 5th, 97232399.6,1999); Automatic control compartment rotary kiln (Shen Guoxiang, China utility model patent ZL 01237607.8, on April 3rd, 2002), direct-reduction process and rotary hearth furnace (Kobe Steel Ltd, Chinese invention patent ZL on November 15th, 00105893.2,2000) or the like.
Through anatomizing the topology discovery of above-mentioned rotary furnace (kiln), above-mentioned rotary furnace (kiln) has all adopted " straight-through structure ", promptly from an endfeed, air inlet, from other end discharging, give vent to anger, the rotary furnace of this structure (kiln) is fit to serialization production, and is easy to operate, but they have the following disadvantages: (a) because raw material is an end advances one and bring out, to react completely in order making, certainly will will to increase the length of rotary furnace, this just causes, and the rotary furnace manufacturing cost strengthens, energy consumption increases, utilization rate is not high; SUMITOMO CHEMICAL and Tokyo tungsten company have just adopted the multi-stage rotary stove to prepare tungsten-cobalt carbide powder (AsadaNobuaki, Rotary furnace, JP on April 24th, 3099192,1991); (b) reaction time of raw material is that raw material is turned back to the required time of the other end from an end, and in fact different raw material reaction asynchronism(-nization)s causes the difficulty of technology controlling and process to strengthen; (c) for batch raw material, its composition can not be fully evenly, and in most cases always have intermediate product to produce, initial feed, intermediate product and end product mix, and cause the purity of made powder not high, uneven components; (d) if make rotary furnace (kiln) keep horizontal rotation, the back discharging that reacts completely can make above-mentioned situation improve, but because powder is substantially mobile in body of heater major diameter direction, so the body of heater temperature difference still can cause the inhomogeneous of material.
Other have the researcher designed the air-flow rotary furnace (Alan W, et al., Apparatus for producing uniform, fine ceramic powder, US Pat.5110565, May 5,1992; Zhang Liying etc., a kind of Processes and apparatus for preparing tungsten carbide-nickel-iron series nanometer grade composit powder, Chinese invention patent ZL 97 1 22085.9, on June 30th, 1999), the body of heater of this air-flow rotary furnace does not rotate, but the effect that utilizes interior vane type centrifugal pump of stove and air-flow drives powder revolution in the stove, and this furnace structure is complicated, and cost is higher.
For simplifying the material powder of technological process, prepared composition and even particle size distribution, be necessary to design a kind of novel device, it can make, and raw material fully contacts with reaction atmosphere, reaction speed is accelerated, reaction temperature reduces, flouring technology parameter (input and output material, atmosphere, temperature) control is easy.A kind of many atmosphere tilting rotary furnace of the special proposition of the utility model.
