Abstract
The invention provides a kind of one-shot forming technique of producing calcium silicate filler used in cylinders soluble acetylene.Intensification gelation moulding, steam press maintenance and the high temperature drying three phases that is characterized in filler is one step completed in a heating unit that exhaust line is housed.Changed originally by post forming in autoclave and the loft drier.Simplified schedule of operation.The time of wanting required for the present invention is short, equipment is few, can improve throughput, reduces floor space and facility investment.Since in the heat-processed, the Heating temperature height, the filler sufficient reacting, so the porosity of filler is even, the intensity height.
Description
The present invention relates to a kind of producing calcium silicate filler used in cylinders soluble acetylene moulding process, particularly producing calcium silicate filler used in cylinders soluble acetylene one-shot forming technique in a heating unit.
The moulding process of the producing calcium silicate filler used in cylinders soluble acetylene that extensively adopts is the extender paste after stirring by certain composition and mixed at present, loads to the acetylene cylinder that is vibrated.After filling, it is inserted in the autoclave, in autoclave, finish the intensification gelation moulding and the steam press maintenance of filler under the full effect of closing steam, again it is shifted out autoclave, move into complete filler high temperature drying in the loft drier, finally finish the moulding process of calcium silicate filling material in acetylene cylinder.Because saturated vapo(u)r is supplied with by high-duty boiler in the autoclave, and the permission top pressure of high-duty boiler is 13kg/cm
2The gauge pressure value closes steam through pipeline satisfying again and be transported to the steam still, so saturated vapor pressure reaches as high as 10～11.5kg/cm in the still
2The gauge pressure value, the full vapour temperature value of closing under this pressure is 183～185 ℃.The temperature of closing steam owing to satisfy in the autoclave is low, causes calcium silicate filling material reaction interior porosity inequality, and intensity is not high.In addition with this in autoclave and loft drier the production cycle of secondary forming process long, needed finish in 13～15 days, the equipment of use is many, floor space is big.
The objective of the invention is to provide a kind of and not only can improve the filler Forming Quality, but also can shorten the production cycle, the moulding process of the producing calcium silicate filler used in cylinders soluble acetylene of simplified apparatus.
Invention is achieved in that loads the extender paste after stirring by certain composition and mixed in the acetylene cylinder that is vibrated, after filling, it is inserted in the heating unit that exhaust line is housed, then bottleneck is connected with exhaust line, heating unit begins heating, begin to rise to 190～200 ℃ from normal temperature, and in heat-processed, regulate the valve on the exhaust line, make the acetylene cylinder internal pressure that extender paste is housed be no more than 16kg/cm through 10～12 hours
2The gauge pressure value is finished filler intensification gelation moulding; And then 190～200 ℃ of constant temperature 10～12 hours, and in thermostatic process, regulate valve on the exhaust line simultaneously, make the acetylene cylinder internal pressure be controlled at 13～16kg/cm
2The gauge pressure value is finished the filler steam press maintenance; Enter the high temperature drying stage then, through 4～5 hours, temperature is risen to 300 ℃ from 190～200 ℃, when continuing to heat up since 190～200 ℃ the valve on the exhaust line is all being opened, pressure is let out to 0kg/cm
2The gauge pressure value.Make the inner pressure release of acetylene cylinder, constant temperature 94 hours after temperature rises to 300 ℃ again, the producing calcium silicate filler used in cylinders soluble acetylene moulding process is finally finished in cooling then.Finish whole process and need 5～6 day time.
Because finish the required time weak point of invention, equipment is few, so can improve throughput, reduces floor space and facility investment.Because invention Heating temperature in heat-processed improves the filler sufficient reacting, so the porosity of filler inside is even, intensity improves simultaneously.Changed in addition originally by post forming in autoclave and the loft drier, thereby simplified schedule of operation.
The present invention is provided by following examples and accompanying drawing thereof:
Fig. 1 is a process flow sheet of the present invention.
Fig. 2 is heating curve figure.
At first, the extender paste after stirring in the mixing of certain composition and ratio is loaded in the acetylene cylinder that is vibrated, fill through 0.5 hour, make extender paste then in acetylene cylinder static 24 hours.In conjunction with the accompanying drawings 1, at the bottle mouth position of the acetylene cylinder 1 that extender paste is housed, install one and can prevent that extender paste is excessive in heat-processed again, the filtration unit 2 that bottle inner vapor is discharged.Then it is inserted in the heating unit 4 that exhaust line 3 is installed, and bottleneck is connected with exhaust line 3.After finishing aforesaid operations, begin heating.Accompanying drawing 2 is heating curve, and ordinate zou T represents the Heating temperature value, and X-coordinate H represents heat-up time, and unit is hour.2 is the heat-processed of filler intensification gelation formative stage from putting 1 to point, and temperature is the normal temperature since 20 ℃, rises to 190 ℃ through 12 hours, regulates valve 5 among Fig. 1 in this course simultaneously, makes bottle the highest 16kg/cm of being no more than of inner vapor pressure
2The gauge pressure value; 3 is the heat-processed in filler steam press maintenance stage from putting 2 to point, 190 ℃ of temperature value constant temperature 10 hours, regulates valve 5 among Fig. 1 simultaneously in this course, bottle inner vapor pressure-controlling at 16kg/cm
2The gauge pressure value, from putting 3 process points, 4 heat-processedes to point 5 are filler high temperature drying stages, from putting 3 heating process temperatures to point 4 is to rise to 300 ℃ from 190 ℃ through 4 hours, simultaneously in this course, valve 5 among Fig. 1 is all opened, make a bottle inner vapor pressure release, and outwards exhaust, from putting 4 heat-processedes to point 5, be 300 ℃ of temperature value constant temperature 94 hours, and in this course, the valve 5 among Fig. 1 is all opened all the time, and bottle steam that interior filler produces is discharged outside the bottle, last again through making temperature reduce to 20 ℃ of normal temperature in 6 hours from putting 300 ℃ of values of 5, then exhaust line among bottleneck and Fig. 13 is thrown off, the acetylene cylinder 1 that filler is housed is shifted out heating unit 4, finally finish one-step moulding process for producing calcium silicate filler used in cylinders soluble acetylene.
