In the past, produced the multiplex deep cooling mechanical crushing method of thermoplastic powder, and utilized plastics to there is the characteristic of brittle temperature, will be cooled to below brittle temperature by crushed material, and by mechanical force, made it be crushed to certain particle size.The brittle temperature of plastics, at-50 ~ 120 ℃, in order to obtain low temperature, adopts liquid nitrogen to make cold-producing medium more, liquid nitrogen is led in pulverizer, or pulverizer is placed in cooling chamber, relies on liquid nitrogen gasification to take away amount of heat, and temperature is dropped to below the brittle temperature of plastics.Deep cooling crush can obtain thinner granularity, and powder is polygon, but equipment investment is large, and liquid nitrogen consumes high, pulverizes the cost that material per ton need to consume thousands of units.This equipment, except configuration in some large-scale petroleum chemical enterprises, can't generally be used.
Increase along with the thermoplastic powder requirement, start to develop the normal temperature mechanical crusher, what occur at first is the turbo blade pulverizer, fixed blade on rotor, in stator inner casing plating pincers annular tooth, after material enters pulverizing chamber, be subject to high speed rotating, the power of being centrifuged is delivered to and is sheared between blade and annular tooth and impact, and when crushing material arrives certain particle size, is sent in classifying screen and carries out classification.Because thermoplastic all belongs to heat sensitive material, can produce a large amount of heats in crushing process, if the temperature of pulverizing chamber can not be taken away in time or be exchanged, material will soften, therefore, the output of normal temperature mechanical crushing is lower, and grinding particle size is thicker.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of compact conformation, easy to operate, grinding rate is fast, Grinding Quality is good, grind thermoplastic grinding machine even, free from environmental pollution.
The technical solution of the utility model is: the utility model is comprised of feed mechanism, abrasive dust fluted disc device, screening plant and dedusting mechanism, wherein feed mechanism connects vacuum feeder by storage bin hopper, then down to vibro-feeder, be connected to the abrasive dust fluted disc device; The abrasive dust fluted disc device is comprised of quiet fluted disc, active toothed disk, temperature control system, mill regulating system, have the cooling bath for cooling media flow in the disk body of quiet fluted disc, temperature control system is connected with active toothed disk, the mill regulating system adopts the worm and gear form, and quiet fluted disc is connected with disk body by bolt with active toothed disk; Screening plant involving vibrations sieve and screen cloth; Dedusting mechanism is to be connected to cyclone separator from air-introduced machine, then arrives sack cleaner.
The beneficial effects of the utility model: because the abrasive dust fluted disc adopts the facile cold water of appearance cooling, so the processing cost of plastic powders is relatively low.The design of Worm-gear type fluted disc adjusting device, make the adjustment of fluted disc gap become more quick, thereby guaranteed output and the quality of product; The temperature control system of setting up, guaranteed the carrying out that the equipment serialization is produced, and improved product yield.Simultaneously cyclone type is inhaled powder, is separated, sieves and the automation of feed back, makes machine construction compactness, work simplification, easy to operate.The design of dust arrester, effectively environmental contamination reduction and recovery resource.
The accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model side schematic views.
The specific embodiment
As shown in accompanying drawing 1, accompanying drawing 2, the utility model comprises feed mechanism, abrasive dust fluted disc device, screening plant and dedusting mechanism.Wherein feed mechanism connects vacuum feeder 2 by storage bin hopper 1, then down to vibro-feeder 3, is connected to the abrasive dust fluted disc device.
The abrasive dust fluted disc device is comprised of quiet fluted disc 4, active toothed disk 5, temperature control system 14, mill regulating system.Have the cooling bath for cooling media flow in the disk body of quiet fluted disc 4, in order to the cooling medium lower than 10 degree is transported in cooling bath with cooling fluted disc by flexible pipe.Temperature control system 14 is connected with active toothed disk 5, and by setting the brittle temperature of ground material, the variations in temperature of monitoring fluted disc, guarantee milling quality.The mill regulating system adopts the worm and gear form, easy to operate, quick, by adjusting the gap between active toothed disk 5 and quiet fluted disc 4, decides output and the quality of ground material.Quiet fluted disc 4 is connected with disk body by bolt with active toothed disk 5, facilitates the fluted disc maintenance and changes.
Screening plant is comprised of vibratory sieve 9 and screen cloth, comminuting matter is drawn into cyclone separator 7 through air-introduced machine 12 and falls into screen cloth by discharge valve 8, by vibrosieve, the powder meeted the requirements is sent from the finished product mouth, underproofly is sent to fluted disc than meal from another exit and again pulverizes processing.
Dedusting mechanism is comprised of cyclone separator 7, discharge valve 8, air-introduced machine 12, sack cleaner 11.The powder overwhelming majority after grinding attracts through air-introduced machine 12, enter cyclone separator 7, fall into vibratory sieve 9 classifications by discharge valve 8 and process, only have the powder of minute quantity to be drawn in sack cleaner by air-introduced machine 12, save and reclaim resource, reduce dust atmosphere and pollute.
In the utility model, quiet fluted disc 4 can be free to remove and replace from disk body with active toothed disk 5, and the tooth bar number on the fluted disc face is to be chosen between the 300-500 bar according to the granularity requirements of required powder.If obtain 80 purpose powder, the tooth bar number of opening system on the fluted disc face that is the 350-500 millimeter at diameter is 500, and with the fluted disc of same diameter, while needing mill 60 purpose powder, the tooth bar number is about 400, during 40 order, is 350 tooth bars.
