Abstract

The hollow ceramic goods generally used the gypsum mould grouting moulding in the past, needed a large amount of gypsum molds, and factory building takes up an area of many, and efficient is low.The pug that present method will contain tailings in vanadium extraction 20-80% extrudes into hole mudboard respectively, solid mud bar, the mud pipe is cut into suitable length, have the biscuit of black porcelain solar heat collecting plate intake-outlet, hollow through simple processing back with pressurization or the mud agglutinating mode formation that fits together, thereby the saving gypsum mold is increased work efficiency.

Description

Method for forming black porcelain solar heat collecting plate

The present invention relates to the hollow ceramic goods, particularly is the forming method of black porcelain solar heat collecting plate of the hollow of one of black colorant and main raw material with the tailings in vanadium extraction.

It is that one of raw material is made the black porcelain goods and carried out the moulding of black porcelain solar heat collecting plate with the gypsum mould grouting method of routine that application number has been narrated with the tailings in vanadium extraction for the CN85106424 patent application.

The hollow ceramic goods, especially there is intake-outlet at two ends, and the hollow plate ceramic products that inner chamber is communicated with uses the moulding of gypsum mould grouting method usually, and this method is used for a large amount of gypsum mold of industrial production needs, takies the big area factory building, production efficiency is lower.

The objective of the invention is to provide a kind of being used for the tailings in vanadium extraction is the high-efficient molding method of porcelain solar heat collecting plate of hollow of one of black colorant and main raw material.

Tailings in vanadium extraction is meant that the molten iron that vanadium titano-magnetite is refined obtains vanadium slag through blowing, the remaining residue that does not almost have use value behind the proposition vanadic salts from vanadium slag.

The invention be achieved in that with tailings in vanadium extraction in rotary kiln through 1150 ℃ of roastings 10 minutes, becoming fineness with the common wet-milling of clay through the tailings in vanadium extraction of roasting is 60-300 purpose mud, be preferably 120～250 orders, mud is removed excessive moisture through the pressure filter press filtration, entering the raw material of ageing silo after old, old promptly becomes required pug through the pug mill pugging, and tailings in vanadium extraction accounts for the 20-80%(butt in the pug).Use three extruding machines, first extruding machine extruded tabular mud bar with holes, second extruding machine extruded solid mud bar, the 3rd extruding machine squeezes sludge out pipe, the tabular mud bar with holes that first extruding machine extruded is cut into the mud plate of suitable length, remove the part pug of the hole partition at foraminous two ends, enter assigned line, the solid mud bar that second extruding machine extruded is cut into suitable length, in position draw a hole and enter assigned line, the mud pipe that the 3rd extruding machine extruded is cut into suitable length, enters assigned line.On assigned line, solid mud bar is attached to hole mudboard foraminous two ends, the mud pipe is inserted in the hole of solid mud bar, just finished the molding procedure of black porcelain solar heat collecting plate biscuit with pressurization or mud agglutinating mode.Drying, sintering just become the black porcelain solar heat collecting plate finished product again, and described pipe has constituted intake-outlet, hollow thermal-arrest plate inner chamber be communicated with as the storage vault of medium or the passage of medium.

Other two kinds of forming methods of black porcelain solar heat collecting plate are:

Be pressed into the plate that one side has groove with above-mentioned pug or with the material powder that makes behind the clay drying, two boards is fit together with pressurization or mud agglutinating mode has just constituted the black porcelain solar heat collecting plate biscuit with intake-outlet and inner chamber connection.

Above-mentioned pug or adding binding agent are made the high-ductility pug through refining mud repeatedly, be rolled into ripple mud plate with roll forming machine, with pressurization or mud agglutinating mode and termination mud bar, the mud pipe fits together and has just constituted the black porcelain solar heat collecting plate biscuit with intake-outlet and inner chamber connection.

The concrete technical process of invention is provided by following examples and accompanying drawing.

Accompanying drawing is the method for forming black porcelain solar heat collecting plate synoptic diagram that proposes according to the present invention.

Describe the method for forming black porcelain solar heat collecting plate that proposes according to the present invention in detail below in conjunction with accompanying drawing.

Will be through 50 parts of the tailings in vanadium extraction of roasting, 50 parts of clays add water, and to wear into fineness in right amount be 200 purpose mud, excessive moisture is removed in press filtration, old 30 days after the pug mill pugging, the moisture 14%(of gained pug all by weight), after extruding respectively, extruding machine 1,2,3 is cut into the hole mudboard 4 of suitable length, solid mud bar 5, mud pipe 6, hole mudboard two stomidium partition A are removed 10 millimeters formation hole mudboards 7 enter assigned line, solid mud bar one end is drawn an aperture to be become mud bar 8 and enters assigned line, and mud pipe 6 enters assigned line.On assigned line with hole mudboard 7, mud bar 8, mud pipe 6 promptly constitutes black porcelain solar heat collecting plate biscuit 9 by pressurizing attaching shown in the accompanying drawing together.

Claims

1, the forming method of hollow ceramic goods particularly is the forming method of the black porcelain solar heat collecting plate of one of black colorant and main raw material with the tailings in vanadium extraction.The pug that it is characterized in that containing tailings in vanadium extraction is through extruding, cut off, draw hole, the resulting hole mudboard 7 of trimming, and mud bar 8, mud pipe 6 are fitted and become to bring into the black porcelain solar heat collecting plate biscuit with communication with cavity of water outlet.

2, the described method of claim 1 is characterized in that tailings in vanadium extraction content is 20-80%(butt weight in the pug)

3, the described method of claim 1, the fineness that it is characterized in that pug is the 60-300 order.
