Abstract
The invention relates to an automatic material clearer. The automatic material clearer is arranged on a vacuum exhaust device above an exhaust hole of an extruder and is characterized in that an automatic control system is connected with a compression cylinder through an upper air pipe and a lower air pipe; the compression cylinder drives a piston to reciprocate up and down under the pushing of high-pressure gas to clear residues in the exhaust hole of the extruder. The automatic control system is used for controlling the acting interval time and the acting frequency. When the piston reciprocates up and down to do a clearing work, the clearing work is carried out under a sealed state. The material clearer disclosed by the invention can be used for automatically clearing accumulated materials in the exhaust hole, and meanwhile, the piston of the material clearer is not in direct contact with a screw rod and a clearer cylinder in a process of executing the clearing action to avoid the damage to the equipment. The automatic material clearer is capable of completely replacing an artificial operation, and energy waste and fund loss generated in artificial clearing are nearly reduced to be zero.
Description
Technical field
The present invention relates to a kind of automatic material clearing device, particularly a kind of polyvinyl chloride conical double screw extruder automatic material clearing device.
Background technology
Domestic in hard adjudicate two cases together ethene extruded product manufacture process at present, many employing cone double screw extruders are processed powder raw material, the machine barrel of cone double screw extruder there is vacuum exhaust pore structure, be used for getting rid of the steam and Small molecular volatile matter that produce in material plasticizing process, to improve the quality of manufactured goods.But there is a great drawback than structure, be exactly extruder in normal productive process, also need the buildup in operating personnel's certain interval of time labor cleaning steam vent, to prevent air-hole blockage.Due to adjudicate two cases together ethene poor heat stability; be attached in the steam vent place short time and will decompose variable color; can the material decomposing variable color be brought in machine barrel in scale removal process; be mixed in the normal material produced; a large amount of impurity waste product pipe is caused to produce; likely can't get out because impurity is attached in mold cavity, and shut down dismounting grinding tool and clear up.What is more, falls in machine barrel after cleaning tool fractures, grievous injury screw rod, machine barrel and mould.
According to the preliminary statistics, every normal production 100 tons of products will produce about 7 tons of waste products because labor cleaning's exhaust, cause about 3 shutdown dismounting to touch tool, the raw material lost thus, the electricity charge, equipment maintenance cost, labour cost huge amount simultaneously.Only calculate with PVC-U drainage pipe, every 100 tons of product aggregate losseses about 6000 yuan.One
the extruder loss of a year is just up to 150,000 yuan.The domestic energy wasted every year in this industry and fund startling.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automatic material clearing device, and this device completely avoid time class waste, and also really reach unmanned streamlined and produce, this is progress and upgrading that PVC extrudes industry.
A kind of automatic material clearing device, on vacuum pumping hardware above the steam vent being arranged on extruder, it is characterized in that: automatic control system is connected compression cylinder by upper tracheae with lower tracheae, compression cylinder is by the promotion of gases at high pressure, thus drive piston to pump, remove the clout in extruder steam vent.
The interval time of described automatic controlling system acting and frequency.
Described piston, when doing up and down reciprocatingly to remove work, carries out in sealed states.
Described piston is fixed through bolt-locking through base, sealing bucket and support bracket fastened bottom plate and prerotation vane, is provided with heat insulation post on the top of prerotation vane, and the lower end of heat insulation post is connected with piston thread through prerotation vane; The body of rod lower end of compression cylinder is connected with heat insulation male screw through thermal insulation board and support bracket fastened upper mounted plate, and is fixed by nut check.
Described fixed support is combined to form by the riser between upper mounted plate, bottom plate and upper and lower fixing plate.
Described prerotation vane is placed in support bracket fastened two riser sides, is connected with riser contact top.
The outer wall of described piston is provided with multiple passage; The lower end of piston is arc shape, matches with the screw rod of extruder.
Compression cylinder is provided with enterprising pore and lower air admission hole.
Described enterprising pore is connected with control system by upper tracheae; Lower air admission hole is connected with control system by lower tracheae.
Automatic control system is made up of time controlled system and gas control system.
The present invention can remove the buildup in steam vent automatically, remove operating frequency to be controlled by optimum configurations, buildup in steam vent also do not formed or undecomposed before be namely eliminated away, in company with the mixed use of machine barrel material, avoid the generation of impurity waste product pipe, simultaneously the piston of this device is performing in the process removing action with screw rod with machine barrel without directly contacting, and avoids the damage to equipment.The present invention can get shape manual operation completely, almost the energy waste produced during labor cleaning and monetary losses can be reduced to zero.
