Utility model content
For the problem of prior art, the purpose of this utility model is the heating and heat-insulating device providing a kind of vacuum belt machine, high temperature can be kept, be applied to liquid phase method produce αsemiwatergypsum and crystal whisker of gypsum produce in Separation of Solid and Liquid time, αsemiwatergypsum generation chemical reaction can be eliminated and become dihydrate gypsum and the phenomenon of solidifying.
The utility model object is realized by following technical solution: a kind of heating and heat-insulating device of vacuum belt machine, described heating and heat-insulating device is an airtight heating and thermal insulation cover, be arranged on the vacuum dehydration belt surrounding of vacuum belt machine, described heating and thermal insulation cover is fixed in the frame of vacuum belt machine, the breather line communicated with it is designed with above described heating and thermal insulation cover, this breather line can inject high temperature air or high-temperature steam, also directly can arrange heat source in stay-warm case.
A kind of selectable technical scheme, along vacuum dehydration belt surface in described heating and thermal insulation cover, be provided with one or more pressure cylinder arrangement, this device is made up of fixed mount, fairlead, electric pushrod, pressure roller, fixed mount is fixed in the frame of vacuum belt machine, there is piston rod described electric pushrod inside, and electric pushrod upper end is connected on fixed mount, and the piston-rod lower end on electric pushrod is fixedly connected on pressure roller; During vacuum dehydration belt carrying material movement, the piston rod of electric pushrod moves downward, and clamps down on pressure roller, pressure roller clamps down on material, impels material to improve packing, accelerates the dewatering speed of material, end-of-job, the piston rod of electric pushrod resets; Centered by described electric pushrod, be arranged with two fairleads, the shell upper end of described fairlead is fixedly connected on fixed mount, and the lower end of its internal slide axle is fixed on pressure roller; The design of fairlead can allow pressure roller more balance and evenly to material applied pressure.
A kind of selectable technical scheme, in order to reach same effect, also along vacuum dehydration belt surface in heating and thermal insulation cover, can arrange other pressue devices one or more, as pressing plate etc.Pressue device clamps down on material, impels material to improve packing, accelerates the dewatering speed of material.
A technical scheme for improvement, described heating and thermal insulation cover is made combined box.Mainly consider that whole heating and thermal insulation cover length is long, be made combined box, be convenient to manufacture and install.
A kind of further improvement opportunity scheme, described heating and thermal insulation cover two ends combination box, the left side of leftmost combination box, opening is offered in the right side of rightmost combination box, is provided with airtight curtain in opening.The vacuum dehydration belt being so both conducive to vacuum belt machine passes through, and is conducive to again the sealing of whole heating and thermal insulation cover.
A technical scheme for improvement, described electric pushrod Air cylinders formula push rod or cylinder type push rod or spring push rod replace.
Advantage of the present utility model:
1, the design of heating and thermal insulation cover, ensure that αsemiwatergypsum serum materials technically, Separation of Solid and Liquid process on vacuum belt machine, there will not be low temperature, thus prevents αsemiwatergypsum that the generation of hydration reaction generation dihydrate gypsum phenomenon occurs under cryogenic.Improve the validity of material Separation of Solid and Liquid, decrease the waste of material, improve economic benefit.
2, the design of pressure cylinder arrangement, can accelerate the dewatering speed of αsemiwatergypsum material, decreases the moisture content after material dewatering.
3, the improvement project of whole vacuum belt machine, structure is simple, easy to manufacture, easy and simple to handle, with low cost, makes the large raising of material solid-liquid separation process efficiency.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
