Abstract
The invention discloses production technology for bakelite powder and a pre-thermoplastic machine thereof. The production technology comprises the steps of: mixing component raw materials, crushing the mixture into powder, stirring the powder uniformly, and adding the powder into an open type plastic purificating set for rubber mixing. The production technology is characterized by adding the powder which is stirred uniformly into a sealed pre-thermoplastic machine for preheating first to make the powder change into slightly fused particles and blocks, and then conveying the particles and blocks to the open type plastic purificating set for rubber mixing. The production technology and the pre-thermoplastic machine thereof effectively solve the problem that a conventional process has flying dust during the rubber mixing of the open type plastic purificating set further to seriously pollute the environment for a long time; and at the same time, the production technology makes a pre-thermoplastic working procedure of a powder raw material which is originally performed in a high-power open type plastic purificating set separated and performed in the pre-thermoplastic machine with a low-power sealing state in advance, which not only greatly reduces the production load of the high-power open type plastic purificating set, but also improves heat utilization rate and thermal efficiency, reduces production energy consumption, and improves production efficiency.
Description
Technical field
The present invention relates to a kind of bakelite powder production technology and pre-heating device thereof.
Background technology
Bakelite powder claims phenolic moulding powder again, is the raw material that insulation, adiabatic equipment are produced in compacting or injection moulding, and its Main Ingredients and Appearance is wood powder, phenolic resins, calcium carbonate, mica powder, calcium hydroxide, curing agent and pigment etc.At present, the technological process of production of bakelite powder is generally: powder → uniform mixing → adding open type plastic purificating set refining glue → colloid thing cooling section → further cooling back pulverizing → metering, the packing of earlier the component raw material being mixed and is ground into 120 order fineness.The maximum disadvantage that above-mentioned traditional handicraft exists is, when the powder of 120 order left and right sides fineness is directly added open type plastic purificating set refining glue, and dust from flying not only in the workshop, environmental pollution is serious, the temperature height, the working environment of workers is abominable, and the energy consumption height.
Summary of the invention
Purpose of the present invention is that above-mentioned traditional bakelite powder production technology is carried out technological improvement, thereby provide a kind of the new bakelite powder production technology that production environment is polluted less and the heat energy utilization rate is high is reached the preheating molding machine supporting with it.
Technical solution of the present invention is:
A kind of bakelite powder production technology, comprise component raw material mixed powder is broken into powder and uniform mixing, add open type plastic purificating set refining glue, the powder that it is characterized in that uniform mixing carries out preheating first the adding in the preheating molding machine that seals, make powder become little molten shot bulk, be transported to open type plastic purificating set refining glue then.
The temperature that the interior powder of described preheating molding machine carries out preheating is controlled at 95～110 ℃.
A kind of preheating molding machine that is used for described bakelite powder production technology, it is made of casing and the screw feeder that is installed in the casing, casing is the cylindrical shell with heating jacket, the cylindrical shell two ends are provided with capping, cylindrical shell one side is provided with the charging interface, another side is provided with the discharging interface, screw feeder is the rotating shaft that the surface is provided with flight, and this rotating shaft is connected with cylindrical shell motor outward.
The rotating shaft of described screw feeder is a hollow shaft, and heater is installed in the hollow shaft.
The invention has the beneficial effects as follows: powder material is handled through pre-thermoplastic earlier made little molten shot bulk, be transported to open type plastic purificating set refining glue then, thereby solved for a long time traditional handicraft dust from flying and difficult problem of serious environment pollution when open type plastic purificating set refining glue effectively; Simultaneously, make the pre-thermoplastic operation of the powder material that originally in the high power open type plastic purificating set, carries out separate, in the preheating molding machine of low-power sealing state, carry out in advance, not only reduced the production load of high power open type plastic purificating set significantly, and heat utilization efficiency, the thermal efficiency have been improved, reduce energy consumption, improved production efficiency.
With the preheating molding machine of this process matching adopt spiral pusher make powder in cylindrical shell in the outlet progradation limit rotation evenly be heated fully while stirring; Design cylindrical shell chuck and hollow center axle heating arrangement simultaneously, reached the big and effect of uniform of heat transfer area; General structure is reasonable, and temperature manipulation is convenient, and running is reliable, thermal efficiency height.
Description of drawings
Accompanying drawing is the general structure schematic diagram of preheating molding machine of the present invention.
The specific embodiment
The invention will be further described with embodiment below in conjunction with accompanying drawing.
The preheating molding machine, it is made of casing 1 and the screw feeder 2 that is installed in the casing 1, casing 1 is the cylindrical shell 12 with heating jacket 13, cylindrical shell 12 two ends are provided with capping 15, cylindrical shell 12 1 sides are provided with charging interface 11, another side is provided with discharging interface 16, screw feeder 2 is rotating shafts 21 that the surface is provided with flight 22, and rotating shaft 21 is connected with the motor 25 of cylindrical shell band decelerator 24 outward.The mode of heating of preheating molding machine can adopt electrical heating or Steam Heating, and present embodiment adopts Steam Heating, directly is provided with steam inlet adapter 14 on the heating jacket 13 of its cylindrical shell 12 and takes over 17 with condensation-water drain; And hollow shaft is adopted in the rotating shaft 21 of screw feeder 2, steam lead 3 is installed in the described hollow shaft, the pipeline section surface that this steam lead 3 is positioned at hollow shaft offers some steam guide holes 31, draws on the described hollow shaft to be connected to the condensation-water drains adapter 23 that extends to outside the cylindrical shell 12.
The bakelite powder technological process of production of the present invention is: earlier the component raw material is mixed and is ground into the powder of 120 order left and right sides fineness, uniform mixing; Be transported to the charging interface 11 of above-mentioned preheating molding machine then by pipeline, start the screw feeder 2 of preheating molding machine this moment, and feed steam to the heating jacket 13 of preheating molding machine cylindrical shell and the steam lead in the hollow shaft 3, heating and temperature control is at 95～110 ℃, the powder that enters preheating molding machine cylindrical shell 12 is under the effect of screw feeder 2, rotation, mixing and stirring to cylindrical shell discharging interface 16 directions and advancing gradually, be heated equably simultaneously and crossfade into little molten shot bulk, discharging from discharging interface 16; Then enter open type plastic purificating set refining glue; Colloid thing cooling section; Further pulverize the cooling back; Metering, packing.
