Abstract
The invention discloses a mineral power calcining dehydration device and relates to productions of mineral power dehydration devices for semi-hydrated gypsum, cement plant clay and the like. A vertical and transverse fire cube structure is used so that the occupied area is reduced greatly, the heat-exchange area is increased and heat in fire cubes are absorbed fully by power. Additionally, by designs of a preheating chamber and an economizer on the tail portion, the heat utilization efficiency is increased and energy can be saved. Coal burns fully without black smoke so that the combustion efficiency is increased. Compared with other structure devices, the mineral powder calcining dehydration device can save 30 to 50 percent coal. The strength of gypsum is increased by at least 30 percent by using flash evaporation technique. By a combination of the mineral powder calcining dehydration device and electronic control technique, controlling temperature is accurate and the product quality is stable. The complete automatic production is achieved. No manual operations are permitted during the whole productive process so that labors are omitted, production cost is saved and the production efficiency is increased.

For achieving the above object, the technical solution used in the present invention is as follows:
Mineral powder calcined dehydration device, comprise furnace wall, described furnace wall inner and upper arranges a pot body, the below arranges burner hearth, described pot body top arranges raw material cabin and steam dust removing device, described burner hearth connects combustion chamber and combustion apparatus, described burner hearth bottom is provided with the ash discharge cinder notch, described pot body is comprised of afterbody preheating chamber and calcining compartment, run through from top to bottom in the described pot body and be provided with agitating device, the fire tube of described pot nside is vertical horizontally set, be connected with feed control between described raw material cabin and the afterbody preheating chamber, be connected with flash vessel between described afterbody preheating chamber and the calcining compartment, one side of described calcining compartment is provided with discharging opening, also comprises the electric control gear of controlling whole device.
The fire tube of described afterbody preheating chamber connects economizer, and described economizer is connected with combustion apparatus by pipeline, and described device for cleaning pipeline is crossed smoke duster and is communicated with external smoke discharging pipe.
Described bottom of pot body arranges urgent drain hole.
Pot body of the present invention adopts the vertical type lateral fire tube structure, greatly limit has reduced floor space, strengthen heat exchange area, made material absorb more fully heat in the fire tube, added the design of afterbody preheating chamber and economizer, thereby greatly improved efficiency of utilization, saved the energy, coal combustion is abundant, without black smoke, improved efficiency of combustion, than the equipment of other modes 30-50% that economizes on coal; Used flash evaporation technology, land plaster intensity has improved more than 30%; This device and the combination of electronic control technology, temperature control is accurate, and constant product quality has realized full-automatic production, and whole production process mustn't manually-operated, saves artificial and production cost, enhances productivity.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Describe the present invention below in conjunction with the drawings and specific embodiments:
Be illustrated in figure 1 as a specific embodiment of the present invention, this mineral powder calcined dehydration device, comprise furnace wall, described furnace wall inner and upper arranges pot body 16, the below arranges burner hearth 9, described pot body 16 tops arrange raw material cabin 11 and steam dust removing device 1, described burner hearth 9 connects combustion chamber 18 and combustion apparatus 19, and described burner hearth 9 bottoms are provided with ash discharge cinder notch 10.
Described pot body 16 is comprised of afterbody preheating chamber 5 and calcining compartment 6, run through from top to bottom in the described pot body 16 and be provided with agitating device 2, the fire tube 17 of described pot body 16 inside is vertical horizontally set, be connected with feed control 4 between described raw material cabin 11 and the afterbody preheating chamber 5, be connected with flash vessel 14 between described afterbody preheating chamber 5 and the calcining compartment 6, one side of described calcining compartment 6 is provided with discharging opening 7, and described pot body 16 bottoms arrange urgent drain hole 8.The fire tube 17 of described afterbody preheating chamber 5 connects economizer 13, and described economizer 13 is connected with combustion apparatus 19 by pipeline 15, and described pipeline 15 is communicated with external smoke discharging pipe by smoke duster 12.Whole calciner plant is controlled realization automatically by electric control gear, and production process need not manually-operated, only need set the parameter such as time and get final product.
The present invention in use, the parameter that sets according to electric control gear, when afterbody preheating chamber 5 needs raw material, raw material in the raw material cabin 11 enters afterbody preheating chamber 5 through feed control 4 and carries out preheating, during raw material after calcining compartment 6 needs preheating, raw material enters calcining compartment 6 through flash vessel 14, this moment, combustion apparatus 22 started, the high-temperature steam that raw material in calcining compartment 6 produces through calcining, enter steam dust removing device 1 by jet chimney 3 and carry out dedusting, steam enters atmosphere, and dust is recycled to tail gas preheating chamber 5, and the product that calcined dehydration is qualified is discharged pot body 16 through discharging opening 7.Agitating device 2 is constantly stirring in the whole process, guarantees constant product quality.The hot flue gas the bottom of a pan in the burner hearth 9; enter the fire tube 17 of pot body 16; enter economizer 13 through afterbody preheating chamber 5; through smoke duster 12 low-temperature flue gas is entered atmosphere; the hot-air that is produced by economizer 13 and mixed by the unburnt coal particulate that smoke duster 12 is collected and to send coal combustion equipment 19 back to by pipeline 15 and carry out secondary and strile-back improves the utilization ratio of heat.When power failure or equipment broke down, material was discharged from urgent drain hole 8.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
