Description
The utility model discloses a kind of banbury, is made of material pressing device, mixing chamber, heater, device for discharging etc.The suitable especially waste or used plastics fusion, mixing of this machine belongs to the recovery technology of plastics.
Banbury is the special equipment of mixing waste or used plastics.Existing banbury is made of institutes such as motor, reduction box, rotor, mixing chamber, material pressing device, device for discharging, heaters.Motor connects the transmission reduction box with yielding coupling, drives a pair of ellipse garden rotor by universal coupling, rotates in mixing chamber, and mixing chamber is by chuck 8-10 kilograms per centimeter
2Steam heated.When pressure head is mentioned by loading hopper adding material.Pressure head presses down fills it up with mixing chamber.Pressure head seals mixing chamber.Ellipse garden rotor rotation stirs material, up to the whole fusions of material, material is drawn off by diaxon rotating opening Dump gate by Dump gate.With the MLX-25 banbury is example, 25 liters of this machine displacement volumes.30 rev/mins of preceding rotor speeds, 35 rev/mins of back rotor speeds.Power of motor is 55 kilowatts.Gross weight is 7.5 tons.
This is confidential asks once reinforced.Because of rotor rotation makes material radially is main motion in mixing chamber.If push down without pressure head, material is then by squeezing back between the two mixing chambers.Material on the one hand by the chuck steam heated, on the other hand by the mechanical shearing frictional heat, and makes the material fusion in mixing chamber.Therefore electrical consumption power is big.The Bulk Specific Gravity of waste and old thermoplastic material is too little, and the banbury that displacement volume is 25 liters once can only obtain 6 kilograms of fused mass.Be mixed with natural fiber in the material, thermal conductivity factor is very low in addition.Material is bigger at the mixing indoor thickness of this machine, and breakdown cycle has also extended.Therefore, existing banbury can not satisfy the technological requirement of the waste and old thermoplastic that is mixed with natural fiber powder, and has the uneconomical disadvantage that equipment investment is big, energy consumption is many.
Above-mentioned deficiency at existing banbury, the purpose of this utility model, promptly provide a kind of mixing natural fiber powder that contains that is fit to, with waste and old thermoplastic is the mixed material of main component, the melting efficiency height, do not produce the thermal degradation disadvantage, energy consumption obviously reduces, the banbury that complete machine weight reduces significantly.
The purpose of this utility model realizes by taking following technical measures.
In by material pressing device, mixing chamber, banbury that heater, device for discharging constituted, mixing indoor configuration has the hollow screw of inside and outside derotation screw thread; The heating centration axis that is positioned at hollow screw is a quill shaft, and the centration axis surface is provided with the axial guiding slot of some; Mixing locular wall is provided with and heats the chuck of the splendid attire conduction oil that oil circuit communicates in the centration axis.
In the technical program, adopt screw rod to promote material.Since the derotation screw rod be a kind of cylindrical shell rubbing surface greater than screw flight at the bottom of the right-handed thread (external screw thread) of footpath rubbing surface, screw rod revolution promotes material advances, and avoids the material in place revolution.And the internal thread of derotation screw rod is that the footpath rubbing surface, blocks material and can not impel material to do axially-movable around the centration axis revolution in the internal thread groove because the centering axial plane is provided with gathering sill greater than the left hand thread of centration axis external diameter rubbing surface at the bottom of the screw rod internal thread.Under the promotion of derotation screw rod, material enters in the mixing chamber derotation external screw thread groove from the charge door bottom.Because shoal gradually at the bottom of the screw thread, material continues to be compacted in being pushed forward process.Under melt temperature, at first begin fusing by conduction oil chuck portion material, skid off by spiro rod rear end at last and fall into mixing chamber back cavity.The pressure that produces after completely when the back cavity material forces material to enter the internal thread of screw rod and the space between centration axis.Because material is pushed ahead in the derotation campaign of internal thread, returns to charge door, enter next fusion circulation on the hole of the junction of hollow screw and transmission main shaft.Enter externally threaded volume of material and obviously dwindle owing to returning once more, and partial melting is arranged, insert the space at the virgin material that does not fall at charge door place and together enter a new fusion cyclic process.Virgin material adds gradually like this, and fusion gradually goes round and begins again to whole material fusions.In order to strengthen the stirring action of material in the melting process, make the probability of material contact heating jacket wall identical, at the outer surface of hollow screw the stirring pin that is circular layout that the discord screw thread intersects is set.If close on the position ring segment that has cutting blade is set at the junction of hollow screw and transmission main shaft hole, then can make be positioned at be subjected to once to shear before internal thread and the interstitial material of centration axis return on by the junction hole, disturbance, thereby change the rule rate that contacts of material and mixing locular wall, material is heated more becomes evenly, help the material fusion.
Technical scheme provided by the utility model, the screw rod of the band derotation screw thread that the male thread portion of hollow screw and plastic extruder are used is identical.Conduction oil in the chuck of material melting temperature is provided, can adopts the electric heater heating, use the coal stove heating kettle, and mode such as the direct heating of coke stove is carried out.Utilize extraction pump that conduction oil is circulated in pipeline.
Banbury provided by the utility model, can realize being mixed with the melting mixing of the waste and old thermoplastic of natural fiber powder, melt temperature that provides and the equilibrium of melt temperature section, can not produce thermal degradation in the melting mixing process, melting efficiency height, complete machine cost are 30% of general banbury and auxiliary device.
