Description
Technical field
The present invention relates to the phenolaldehyde moulding compound manufacture field, especially relate to a kind of phenolaldehyde moulding compound fine powder separator.
Background technology
In recent years, in the processing of phenolaldehyde moulding compound product moulding since high efficiency injection mo(u)lding in a lot of processing space conjunction generations compression molding, outside the phenolaldehyde moulding compound depolarization special demand; All requiring outward appearance is the shot-like particle of no fine powder, and to satisfy the reinforced of injection mo(u)lding and plasticizing requirement, promptly moulding compound has easily reinforced; Plasticizing is fast, quick solidifying, and the demoulding is easy; Be difficult for producing micro-molecular gas, product surfacing, characteristics such as moulding process broad.This has just proposed new requirement to the powder shape and the particle diameter distribution of phenolaldehyde moulding compound, particularly requires the above fine powder of 80 orders few more good more.
The phenolaldehyde moulding compound production at home and abroad overwhelming majority adopts pair roller mills heating raw material, roll-in refining to be moulded the technology of sheet, the pulverizing of cooling back.Domestic majority producer adopts cintrifugal disintegrator at present; Form has hammer, blade type, toothed disc type, turbine type etc.; Also have part producer to adopt the grinding roller pulverizer to pulverize, but these methods all can not reach the requirement of expection, the above fine powdered thing of 80 orders accounts for 15～35% of total amount.Be to reduce the fine powder amount in the finished product, adopt usually pulverize after, through the suction of high pressure positive blower negative pressure, cyclonic separation gather materials, vibration separation screen sieves, and removes the above fine powder of most of 80 orders.But when cyclonic separation, get in the cyclone separator at a high speed owing to all materials, and rotation at a high speed in cyclone separator, material and cyclone separator inwall produce friction, make the increase of fine powder total amount; When vibration separation screen sieves, because the high vibration of material on compass screen surface causes material to clash into mutually, rub, the fine powder total amount is further increased, also produce bigger vibrating noise simultaneously.
Summary of the invention
The present invention is intended to propose a kind of phenolaldehyde moulding compound fine powder separator, can the fine powder in the phenolaldehyde moulding compound be separated simply, efficiently, obtains satisfied phenolaldehyde moulding compound product, and avoids in separation process, further producing fine powder, reduces the fine powder total amount.
This phenolaldehyde moulding compound fine powder separator comprises finished product storage tank, wind-force fine powder pre-separate device, tube connector, fine powder grading plant and closes the wind discharger.Wind-force fine powder pre-separate device and fine powder grading plant all are installed in the top of finished product storage tank.Wind-force fine powder pre-separate device comprises air channel and stuff-spraying pipe.The cross section in air channel is a rectangle, vertical layout, and the end face of finished product storage tank is passed in the bottom in air channel, and the outer wall in air channel links to each other with the end face sealing of finished product storage tank, and the opening of the lower end in air channel is positioned at the finished product storage tank, and there is air outlet the upper end, air channel.Stuff-spraying pipe horizontal arrangement, stuff-spraying pipe are passed the sidewall of finished product storage tank, and the outer wall of stuff-spraying pipe links to each other with the sealing of finished product storage tank sidewall, and the import of stuff-spraying pipe is positioned at outside the finished product storage tank, and the outlet of stuff-spraying pipe is positioned on the sidewall of bottom, air channel.Described fine powder grading plant comprises housing, grading wheel, discharge pipe, motor and labyrinth gland.It is oblate that housing becomes, and grading wheel is positioned at housing, and motor is fixed on the center of the bottom surface of housing, and the axle of motor seals with the bottom surface of housing through labyrinth gland mutually.The upper end of the axle of motor is stretched in the housing, and grading wheel is fixed on the axle of motor, and the top of grading wheel is uniform-distribution with a circle blade, and blade radially is provided with and upwards stretching, extension along grading wheel, forms a leaf road between per two adjacent blades.A charging aperture is arranged on the sidewall of housing, and this charging aperture links to each other with the air outlet of wind-force fine powder pre-separate device through tube connector.There is an exhaust outlet at the center of the upper bottom surface of housing, and this exhaust outlet links to each other with the import of discharge pipe.One side of housing bottom surface has a discharging opening; Pass wind discharger is positioned at the below of above-mentioned discharging opening; The import of closing the wind discharger links to each other through discharge nozzle with above-mentioned discharging opening, and the outlet of closing the wind discharger is connected with the finished product storage tank through the conveying pipeline on the roof of finished product storage tank.
The import of the stuff-spraying pipe of this phenolaldehyde moulding compound fine powder separator is linked to each other with Material pipeline; The outlet of discharge pipe is linked to each other with dust collecting system through exhaust duct; Already pulverised phenolaldehyde moulding compound powder is sucked by Material pipeline; Get in the wind-force fine powder pre-separate device, the phenolaldehyde moulding compound powder is under the effect of carrying inertia and deadweight, and the suction that most of qualified particulate material overcomes wind gets into the finished product storage tank.Fine powder more than 80 orders is carried a small amount of particle diameter secretly and is got into the fine powder grading plant greater than the qualified particle of 80 purposes under the effect of the suction of wind.In the fine powder grading plant, powder gets in the classification wheel blade road, receives the effect of grading wheel rotary centrifugal force; Qualified powder greater than Cut size is thrown out of, separates, and gets into the finished product storage tank through the wind discharger that reaches a standard, and recycles through exhaust duct entering dust collecting system less than the fine powder of Cut size; Thereby the fine powder in the phenolaldehyde moulding compound powder is separated simply, efficiently, obtain satisfied phenolaldehyde moulding compound powder product, and avoid in separation process, further producing fine powder; Reduce the fine powder total amount, thereby reduce finished product fine powder secondary refining glue ratio, enhance productivity; Guarantee product quality, avoided simultaneously adopting the vibration separation sieve classification and the vibrating noise produced.This apparatus and process is simple, cost is low, and can be with pulverizing, negative pressure suction in the phenolaldehyde moulding compound production process, finished product gathers materials and process slitless connection such as storing.
