Quan Xing.
(2) present invention by setting particle moulding net, when some liquid fall in particle moulding it is online when can fall in breathing at
It is some of incoagulable directly in bottom collection breathing molding ball and connect telescoping tube on the surface of type ball and connection telescoping tube
Form droplet to fall, is directly condensed on breathing molding ball and connection telescoping tube there are also some, pass through respiration tracheae and distribution
Pipe is to can make breathing molding ball, connection telescoping tube and stripping when gas transmission inside particle moulding net and air-breathing, gas transmission and air-breathing
Deformation occurs for grain spring, and the breathing molding ball and connection telescoping tube that deformation occurs directly remove the solid of the condensation on surface, together
When the stripping grain spring that deformation occurs constantly rub breathing molding ball and connection telescoping tube, isolated agglomeration is wiped off and in breathing
Molding ball and connection telescoping tube, which are shunk when intermediate space increases, to be fallen down, and particle moulding net is on the one hand avoided to be condensed resistance
It the case where hindering equipment to use, on the other hand can be to avoid the loss of material.
(3) present invention rubs grain plate with the hands by the way that broken grain plate and steel wire is arranged, when the big grumeleuse removed on the net from particle moulding is fallen
When travelling sieve grain is online, to shake cloth, shake cloth drives the shake of travelling sieve grain net for the wind of inclination hot air pipe blowout, and
Material is trembled between broken grain plate and travelling sieve grain net, is broken between grain plate and travelling sieve grain net in the process of travelling sieve grain net shake
In continuous extrusion friction, break grain plate and the online steel wire of travelling sieve grain rubbed grain plate with the hands and will be formed on ball and connection telescoping tube from breathing
The very thin shelly-shaped solid crushing separated, which is opened, to become smaller, and is then detached from travelling sieve grain net in dither process and falls down, from
And all cured phenolic resin can be made to granulate.
(4) when in use, the liquid sublimation separated after phenolic resin curing rises and in liquid autoclave the present invention
Top liquefy to the cold, the inside of collecting tank is then slided on the roof of arc, to reduce the product of grain forming pot bottom
Water.
The present invention is by being arranged tetragonous broken grain block and broken shell bore spine, on the one hand, when phenolic resin liquid sprays and strikes
When on tetragonous broken grain block, it can be broken and separate by the corner angle on tetragonous broken grain block surface, drop further be broken, on the other hand when tetragonous
Broken grain block and broken shell bore spine are broken with that can puncture the shell of solidification when particle moulding net is expanded and shunk, and
Broken shell bore spine scrape effect under be more convenient be detached from fall.
(5) present invention can be drawn when shaking cloth and travelling sieve grain net is shaken by setting deformation traction rope
Deformation traction rope is shaken, and can draw in deformation traction rope dither process and lead particle moulding net with deformation along particle moulding net
The downward drawstring of the tie point of messenger, during particle moulding net is shunk between each breathing molding ball of meeting further expansion
Gap facilitates falling off for shell.
(6) present invention directly directly granulates the phenolic resin of liquid from liquid state, and is directly solidified, and avoids digging
Big and cutting phenolic resin, and facilitate subsequent attrition process, so that the general phenolic resin preparation equipment of effective solution exists
When by materiel machining at smaller particle, working strength is larger, needs more labour, and cuts and grind and exist centainly
Security risk, the block shape that remains unchanged of the material after cutting is larger, and higher problem is lost in grinding spring slag.
(7) present invention can be improved phenolic aldehyde by the material vacuum preliminary hydro-extraction to mixed phenolic resin
The concentration of resin raw material can be improved the speed that subsequent phenolic resin is directly granulated from liquid state, by heat preservation high wind pipe
Inlet access atomizer, by be passed through high wind and make atomizer to heat preservation high wind pipe in spray into 8% atomization black Lip river
Tropine can be improved the speed of phenolic resin particle shape, and then improve preparation efficiency.
