Abstract
The utility model discloses an Alpha type semi-hydrated gypsum still kettle which comprises a horizontal type still kettle body. The still kettle body is provided with a feeding end cover and a discharging end cover, wherein a hot oil heating device is installed on the wall of an inner cavity of the still kettle body, and connected at the outside of the still kettle body by a hot oil conducting pipe; the still kettle body is also provided with a steam inlet, a steam outlet and a water outlet; the Alpha type semi-hydrated gypsum still kettle is heated by adopting the double heat sources of conducting hot oil and the steam, improves the self temperature of plaster, does not need to be filled with water independently before heating, thus reducing operation steps; and during the crystal transition process of the plaster, the crystal transition is quick and good, and the product has quick water filtering speed, high strength and good toughness.
Description
Technical field
The utility model relates to a kind of autoclave of producing alpha semi-hydrated gypsum.
Background technology
Produce at present alpha semi-hydrated gypsum and generally use steam boiler to be thermal source, can also can indirect heating with the steam direct heating.Need to be carried out at again after the direct heating dehydration dry, so be called two step method.Indirect heating can be finished dehydration and drying in an equipment, so be called single stage method again.Use steam to be thermal source. the pressure ratio of steam is higher, to the safety requirements of equipment also than higher, the temperature instability of well and steam, gypsum in changeing brilliant process, change brilliant slow, to change the crystalloid amount low; The product of producing, drainage is slow, intensity is low, poor toughness, and product stability is low.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly changes brilliant fast, it is brilliant good and product drainage that produce is fast, intensity is high, the alpha-type semi-hydrated gypsum autoclave of good toughness to change.
For solving the problems of the technologies described above, the technical solution of the utility model is: alpha-type semi-hydrated gypsum autoclave, comprise horizontal autoclave body, described autoclave body is provided with charging end cap and discharging end cap, on the inner chamber chamber wall of described autoclave body the deep fat heating unit is installed, it is external that described deep fat heating unit is connected to described autoclave by heat-conducting oil pipes, also is provided with steam inlet on the described autoclave body, also be provided with the steam bleeding mouth on the described autoclave body, the bottom of described autoclave body is provided with water outlet.
As optimized technical scheme, on the described autoclave body tensimeter and thermometer are installed.
As optimized technical scheme, on the described autoclave body safety valve is installed.
Owing to adopted technique scheme, alpha-type semi-hydrated gypsum autoclave, comprise horizontal autoclave body, described autoclave body is provided with charging end cap and discharging end cap, on the inner chamber chamber wall of described autoclave body the deep fat heating unit is installed, it is external that described deep fat heating unit is connected to described autoclave by heat-conducting oil pipes, also is provided with steam inlet on the described autoclave body, also be provided with the steam bleeding mouth on the described autoclave body, the bottom of described autoclave body is provided with water outlet; Described alpha-type semi-hydrated gypsum autoclave, adopt the two thermals source heating of thermal oil and steam, improve the gypsum self-temperature, and needn't water filling in autoclave separately before the heating, reduced operation steps, commentaries on classics is brilliant soon, commentaries on classics is well brilliant and product drainage that produce is fast, intensity is high, good toughness.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment
As shown in drawings, alpha-type semi-hydrated gypsum autoclave, comprise horizontal autoclave body 1, described autoclave body 1 is provided with charging end cap 6 and discharging end cap 8, on the inner chamber chamber wall of described autoclave body 1 deep fat heating unit 2 is installed, described deep fat heating unit 2 is connected to outside the described autoclave body 1 by heat-conducting oil pipes 11, also is provided with steam inlet 9 on the described autoclave body 1, also be provided with steam bleeding mouth 4 on the described autoclave body 1, the bottom of described autoclave body 1 is provided with water outlet 7.Tensimeter 3 and thermometer 5 are installed on the described autoclave body 1, on the described autoclave body 1 safety valve 10 are installed.
Use described alpha-type semi-hydrated gypsum autoclave, adopt the two thermals source heating of thermal oil and steam, improve the gypsum self-temperature, simultaneously needn't water filling in autoclave separately before heating, reduced operation steps.Alpha semi-hydrated gypsum after the dehydration can be proceeded drying operation in the autoclave body, and the ratio of heat capacities of thermal oil is bigger, heat supply is stable, under lower pressure, can reach higher temperature, had the direct-fired advantage of steam concurrently, gypsum is in changeing brilliant process, and commentaries on classics is brilliant soon, commentaries on classics is well brilliant and product drainage that produce is fast, intensity is high, good toughness, mark thick 43%-44%, folding strength reached 5.0-5.5mpa, intensity raising 50%, constant product quality in 2 hours.
Above-described only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, distortion of making and improvement also should be considered as protection domain of the present utility model.
