Description

A kind of pretreatment system of industrial gypsum

Technical field

The invention belongs to building field, particularly to the pretreatment system of a kind of industrial gypsum of a kind of processing method that industrial gypsum is converted into plaster of Paris.

Background technologyWith

The industrial gypsum of indication in the present invention, mostly refer to ardealite, ardealite is to produce phosphatic a kind of side-product, it it is the insoluble difficulty of one faced in detergents and cosmetic and related chemistry commercial production, each producer spends substantial amounts of place and expense for storing and processing ardealite, cause severe contamination to surrounding enviroment, annoying the production and operation of relevant enterprise；Along with the coal-burning boiler raising to emission request, the side-product that wherein sulfur removal technology produces also is Gypsum Fibrosum；Gypsum Fibrosum application on building materials is that the Gypsum Fibrosum containing two water of crystallization is sintered into the Gypsum Fibrosum containing half water of crystallization, referred to as semi-hydrated gypsum mostly；In the calcination process of dihydrate gypsum, Gypsum Fibrosum is heated to 130⁰C-230⁰C so that separate out containing free moisture and water of crystallization in Gypsum Fibrosum, become semi-hydrated gypsum, in order to be applied to building field；At present, mostly use stove external heat, control in-furnace temperature 165⁰About C, through after a while, makes dihydrate gypsum become semi-hydrated gypsum, when temperature is more than 230⁰C, will change into anhydrous gypsum, and Gypsum Fibrosum is a kind of construction material that building trade is conventional, has setting rate fast, lightweight, adhesive strength advantages of higher；Be commonly used as construction material is semi-hydrated gypsum, owing to ardealite being dihydrate gypsum and the phosphate ion containing remnants mostly, and fluoride etc., use conventional gypsum calcining and processing method cannot be converted into the Gypsum Fibrosum that can be used for construction material.Ardealite is converted into plaster of Paris when, owing to ardealite contains the phosphate anion of acidity, the plaster of Paris after dinectly bruning can cause conversion does not affect the use in architectural engineering in acidity；And ardealite contains substantial amounts of natural moisture, during ardealite is converted into plaster of Paris, dinectly bruning, the conglomeration of ardealite can be caused, can convert after ardealite surface calcining after conglomeration, and the internal substantial amounts of ardealite of conglomeration will not be calcined and the most also will not participate in conversion, thus reduce the conversion ratio that ardealite converts to plaster of Paris.

Summary of the invention

The problems referred to above existed during being converted into industrial gypsum for existing ardealite, the present invention proposes the pretreatment system of a kind of industrial gypsum, it is characterised in that: include Factory Building, neutralize device, distribution device, conveyer device, loading attachment；The roof of described Factory Building or roof and enclosure wall are made of clear material；The described device that neutralizes is arranged on the top of Factory Building one end；It is unsettled that described distribution device is arranged on Factory Building middle and upper part；Described distribution device has more than one；Described conveyer device is arranged on the ground of Factory Building, is positioned at beyond the cloth scope of distribution device；Described loading attachment is arranged on the ground of Factory Building, is positioned at the side of conveyer device, and can move along conveyer device side；Described neutralization device, conveyer device, loading attachment is auto-controll operation.

Beneficial effect

The beneficial effects of the present invention is, it is capable of industrial gypsum and is converted into the pretreatment of plaster of Paris, the acid ion being reduced or eliminated in industrial gypsum, the moisture content of the industrial gypsum being lowered in calcining furnace, and then raising industrial gypsum are converted into the conversion ratio of plaster of Paris.

Accompanying drawing explanation

Fig. 1 is the structural representation of the present invention

1. Factory Building, 2. in and device, 3. distribution device, 4. conveyer device, 5. loading attachment.

Detailed description of the invention

In order to further illustrate technical scheme, in conjunction with accompanying drawing, further illustrate the detailed description of the invention of the present invention；As Fig. 1, this example used the roof of Factory Building 1 and enclosure wall are all transparent material, this example use steel structure frame glazing realize；Neutralization device 2 is arranged on the top of one end, house；Distribution device 3 is arranged on Factory Building 1 middle and upper part unsettled；This example use two distribution devices 3 be evenly arranged in Factory Building horizontal cross-section；Conveyer device 4 is arranged on the ground of Factory Building, is positioned at beyond the cloth scope of distribution device 3；Loading attachment 5 is arranged on the ground of Factory Building, this example uses the industry general or the automatic of grain reserves industry universal is collected with rehandling facilities as loading attachment 5, this example is selected two loading attachments 5, is positioned at the dual-side of conveyer device 4, it is possible to move along conveyer device 4 side；This completes the enforcement of the present invention；During application, industrial gypsum and the neutralization desiccant alkaline matter upper inlet from Factory Building 1 one end enter and neutralize device 2, use quick lime as neutralizing desiccant alkaline matter in this example；Neutralizing device 2 to carry out quick lime and industrial gypsum sufficiently proportionally mixing and stirring, under general industrial gypsum naturalness, moisture content is mostly about 25%, through the mixing of quick lime, it is possible to the moisture content of industrial gypsum is lowered about 6%；Mixed industrial gypsum is under the effect of quick lime, and its internal acid ion neutralizes with quick lime, is removed by acid ion or major part is removed, it is ensured that the residual of acid ion meets the standard criterion of plaster of Paris；It is sent to distribution device 3 through neutralizing the mixed industrial gypsum of device 2, distribution device 3 is aerial owing to being arranged on, mixed industrial gypsum has one shed process and be dispersed in the ground of Factory Building 1, and in adding Factory Building 1, temperature is high, beneficially the moisture evaporation of industrial gypsum；Owing to roof and the enclosure wall of Factory Building 1 have employed transparent material and make, it is internal that sunlight can be irradiated to Factory Building 1, industrial gypsum temperature in Factory Building 1 is raised, accelerate the evaporation of contained humidity in industrial gypsum, save the substantial amounts of energy, because existing industrial gypsum drops in low-moisture method, industrial gypsum per ton often reduces the moisture of 1%, needs substantial amounts of standard coal；Industrial gypsum after reducing moisture, through loading attachment 5, collects and is loaded on conveyer device 4；Owing to this example using the loading attachment 5 automatically controlled, reduce labor intensity and achieve automatization；Neutralize and the effect of solar energy Factory Building 1 through quick lime, the pretreated industrial gypsum being referred to as meeting gypsum calcining requirement of industrial gypsum, delivered to calciner by conveyer device 4 calcine, prevent and produce the defect that conglomeration is unfavorable for calcining and converting owing to industrial gypsum moisture content is high, improve industrial gypsum and be converted into the conversion ratio of plaster of Paris.
