Abstract
A preheating molding machine used for bakelite powder production techniques consists of a casing and a spiral stock pusher arranged in the casing. The casing is a barrel provided with a heating jacket, the two ends of the barrel are provided with seal covers, one side of the barrel is provided with a feed inlet, and the other side is provided with a discharge outlet. The spiral stock pusher is a rotating shaft of which the surface is provided with spiral blades, and the rotating shaft is connected with a motor outside the barrel. Powder is rotated, agitated and uniformly heated when the powder is pushed in the barrel to an outlet by the spiral stock pusher. The design of the structure that the barrel jacket and the hollow central shaft are simultaneously used for heating makes heat transfer area large and uniform. The utility model has the advantages of reasonable integral structure, convenient temperature control, reliable operation and high thermal efficiency.
Description
Technical field
The utility model relates to the powder firing equipment in a kind of bakelite powder production technology.
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.For overcoming above-mentioned disadvantage, the applicant has designed powder material has been made little molten shot bulk through pre-thermoplastic processing earlier, is transported to the bakelite powder production new technique of open type plastic purificating set refining glue then.
Summary of the invention
The purpose of this utility model is to provide supporting preheating molding machine for above-mentioned bakelite powder production new technique.
Technical solution of the present utility model is:
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 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 beneficial effects of the utility model are: adopt spiral pusher make powder in cylindrical shell in the outlet progradation limit rotation evenly be heated fully while stirring; And designed cylindrical shell chuck and hollow center axle while heating arrangement, make heat transfer area big and even; General structure is reasonable, and temperature manipulation is convenient, and running is reliable, thermal efficiency height.
Description of drawings
Accompanying drawing is a general structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail 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.。
