Description
Technical field
The invention belongs to building field, more particularly to the one of a kind of processing method converting industrial gypsum to building gypsum
The pretreatment system of kind industrial gypsum.
Background technology
Signified industrial gypsum in the present invention refers to ardealite mostly, and ardealite is a kind of phosphatic byproduct of production,
It is a kind of insoluble difficulty faced in detergents and cosmetic and related chemistry industrial production, each producer spends a large amount of
Place and expense cause seriously to pollute, annoying the production warp of relevant enterprise for storing and handling ardealite to surrounding enviroment
Battalion；The byproduct that raising with coal-burning boiler to emission request, wherein sulfur removal technology generate is also gypsum；Gypsum is in Building wood
Application on material is that the gypsum that will contain there are two the crystallization water is sintered into the gypsum containing half of crystallization water, referred to as half water stone mostly
Cream；In the calcination process of dihydrate gypsum, gypsum is heated to 1300C-2300C so that contain free moisture and crystallization in gypsum
Elutriation goes out, and becomes semi-hydrated gypsum, to be applied to building field；Currently, mostly using stove external heat greatly, control in-furnace temperature exists
1650C or so, after a period of time, making dihydrate gypsum become semi-hydrated gypsum, when temperature is more than 2300C will be converted to anhydrous stone
The advantages that cream, gypsum are a kind of building trade commonly construction materials, have setting rate fast, light-weight, and adhesive strength is high；Often
Be commonly used for construction material is semi-hydrated gypsum, due to being dihydrate gypsum and containing remaining phosphate ion mostly in ardealite,
Fluoride etc. can not be converted into the gypsum that can be used for construction material using conventional gypsum calcining and processing method.It is inciting somebody to action
When ardealite is converted into building gypsum, since ardealite contains acid phosphate anion, dinectly bruning can cause to convert
Building gypsum afterwards is in acid without influencing the use in architectural engineering；And ardealite contains a large amount of natural moisture,
During ardealite is converted into building gypsum, dinectly bruning can cause the conglomeration of ardealite, and the ardealite surface after conglomeration is forged
It can be converted after burning, and a large amount of ardealite will not be calcined therefore will not participate in conversion inside conglomeration, to reduce ardealite
The conversion ratio converted to building gypsum.
Invention content
It is converted into the existing above problem during industrial gypsum for existing ardealite, the present invention proposes a kind of work
The pretreatment system of industry gypsum, it is characterised in that：Including workshop, device, distribution device, conveying device, loading attachment are neutralized；Institute
The roof or roof of the workshop stated and enclosure wall are made of clear material；The device that neutralizes is mounted on the upper of workshop one end
Portion；It is hanging that the distribution device is mounted on workshop middle and upper part；The distribution device is there are one more than；The conveying device
Mounted on the ground of workshop, it is located at other than the cloth range of distribution device；The loading attachment is mounted on the ground of workshop, position
In the side of conveying device, and can be moved along conveying device side；The neutralization device, conveying device, loading attachment are
Auto-controll operation.
Advantageous effect
The beneficial effects of the present invention are can realize that industrial gypsum is converted into the pretreatment of building gypsum, reduce or disappear
Except the acid ion in industrial gypsum, it is lowered into the moisture content of the industrial gypsum in calcining furnace, and then improves industrial gypsum and turns
Turn to the conversion ratio of building gypsum.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention
1. workshop, in 2. and device, 3. distribution devices, 4. conveying devices, 5. loading attachments.
Specific implementation mode
Technical solution in order to further illustrate the present invention, in conjunction with attached drawing, the specific implementation that further illustrates the present invention
Mode；Such as Fig. 1, using the roof of workshop 1 and enclosure wall all it is transparent material in this example, glass is embedded in using steel structure frame in this example
Glass is realized；Top of the device 2 mounted on house one end will be neutralized；It is hanging that distribution device 3 is mounted on 1 middle and upper part of workshop；This example
It is middle to be evenly arranged in workshop horizontal cross-section using two distribution devices 3；Conveying device 4 is mounted on to the ground of workshop, is located at cloth
Other than the cloth range for expecting device 3；Loading attachment 5 is mounted on to the ground of workshop, in this example using the industry it is general or
The automatic collection of grain reserves industry universal and rehandling facilities are used as loading attachment 5, and two loading attachments 5, general are selected in this example
It is located at the two sides of conveying device 4, can be moved along 4 side of conveying device；This completes the implementations of the present invention；Using
When, industrial gypsum and the desiccant alkaline matter of neutralization enter neutralization device 2 from the upper inlet of 1 one end of workshop, are adopted in this example
Use quick lime as the desiccant alkaline matter of neutralization；Neutralize device 2 by quick lime and industrial gypsum carry out adequately according to than
Example mixing and stirring, moisture content is mostly 25% or so under natural conditions for general industrial gypsum, by the mixing of quick lime, energy
Enough moisture content by industrial gypsum lower 6% or so；Mixed industrial gypsum is under the action of quick lime, internal acidity
Ion is neutralized with quick lime, by acid ion removal or most of removal, ensures that the residual of acid ion meets building gypsum
Standard criterion；It is sent to distribution device 3 by neutralizing 2 mixed industrial gypsum of device, distribution device 3 is due to being mounted on sky
In, by mixed industrial gypsum there are one shedding process and being dispersed in the ground of workshop 1, plus temperature height in workshop 1, it is conducive to
The moisture evaporation of industrial gypsum；It is made since the roof of workshop 1 and enclosure wall use transparent material, sunlight can be irradiated to workshop 1
It is internal so that the industrial gypsum temperature in workshop 1 increases, and accelerates the evaporation of contained humidity in industrial gypsum, saves a large amount of
The energy, because existing industrial gypsum drops in low-moisture method, industrial gypsum per ton often reduces by 1% moisture, needs a large amount of
Standard coal；Industrial gypsum after reducing moisture is collected and is loaded into conveying device 4 by loading attachment 5；
Since, using the loading attachment 5 automatically controlled, reducing labor intensity realizes automation in this example；By quick lime neutralize and
The effect of solar energy workshop 1, industrial gypsum are pretreated the industrial gypsum for being known as meeting gypsum calcining requirement, by conveying device 4
It is sent to calciner to be calcined, it is therefore prevented that generate conglomeration due to industrial gypsum moisture content height and be unfavorable for calcining and convert scarce
It falls into, improves the conversion ratio that industrial gypsum is converted into building gypsum.
