After the particulate material of leaking down from sand storage bin 103 enters rubbing mechanism 108, under the wind-force effect, carry out wind and wash brokenly sand demoulding process.Wash by wind, sand grains is crushed to former fineness of sand; Simultaneously, also sloughed attached to the part of the adhesive film on the particle.
It is as follows that concrete wind is washed process:
After the high-pressure blast that Blast mechanism 105 produces is blown into the blast channel 106 of 101 inside, rubbing chamber, air communication is crossed the gap between the blast channel 106 upper and lower contour plates, enter between every block of sand block plate of whole rubbing mechanism 108, see also the arrow points among Fig. 3, Fig. 5, air-flow flows in the passage that a plurality of sand block plates constitute, and drives current downflow on the particulate material.In the motion process, particulate material constantly bumps and rubbing each other.
Particulate material is under the aerodynamic effect of Blast mechanism 105 and the deduster air inducing that are connected with dust discharge adapter 107 outsides, collide the sand block plate, or navigate between the space of numerous sand block plates, form between particle and baffle plate or mutual bump between particle and the particle and mutual rubbing.Behind multiple impact and rubbing, sand grains is crushed to former fineness of sand, and the adhesive film part is come off; Small dust through washing generation by rubbing with the hands and film bits are discharged with air-flow.The clean sand particulate material that obtains after wind is washed falls into vibratory sieve 2, and weary gas and dust etc. are taken over 107 by dust discharge and entered deduster, filter the back discharging at last, and wind is washed process and finished.
Clean the sand particulate material and enter vibratory sieve 2, drop on be in tilted layout the sieve plate of sieve nest 202 on, under the exciting force effect that vibrating motor produces, sand grains is clashed into once more and is exchanged views, sand storehouse 3 in the middle of qualified sand grains sees through and enters after sieve plate leaks down; Mixtures such as larger-size sintered particles and clipped wire then flow to slag-drip opening along the sieve nest 202 that tilts under the gravity effect, and discharge by deslagging elephant trunk 205.The dust that the middle a small amount of stranding that produces falls is taken away by rubbing chamber negative-pressure air-flow.
The purpose in sand storehouse 3 is to store through vibratory sieve 2 to handle the qualified sand material that obtains in the middle of being provided with.For guaranteeing the work effect of the described casting sand recycling device of the utility model embodiment, the sand material in the middle sand storehouse 3 must remain certain reasonable amount.If the material level of particulate material is high to the sieve plate bottom surface, vibratory sieve 2 just can't operate as normal; Otherwise if material level is low to sand temperature modulator 4 can not be full of, then the heat exchange effect of sand temperature modulator 4 will weaken.

Step 6 is regulated the sand temperature, makes reclaimed sand meet the sand mulling craft requirement
The reclaimed sand temperature that obtains after the processing of operations such as process knockout, pre-regeneration, rubbing, wind are washed, screening is still very high, can not satisfy arts demand, must cool off temperature adjustment to it and handle.
The higher reclaimed sand of temperature is full of sand temperature modulator 4, and its heat constantly passes to cooling medium by the heat exchange tube wall.Take heat out of by cooling medium circulation system, make the medium temperature keep stable, the sand temperature is able to constantly reduce by the diabatic process that continues.When the thermometer of sediment outflow lock top recorded the sand temperature and meets technological requirement, pneumatic sediment outflow lock 403 was just opened automatically and is put sand.When the sand temperature did not meet technological requirement or middle sand storehouse and is in low material level, pneumatic sediment outflow lock 403 can cut out automatically and stop to 5 dischargings of bottom sand hopper.
In order to reach better cooling effect, we can add the refrigeration machine (not shown) in cooling procedure, accelerate the cooling velocity of cooling medium, and improve cooling effect.
Step 7, the storage of qualified reclaimed sand and conveying
The above-mentioned reclaimed sand that meets the casting technique needs is after pneumatic sediment outflow lock 403 falls into bottom sand hopper 5, and the air-transport system in the exit by bottom sand hopper 5 transports.
The described casting sand recycling device of the utility model embodiment has had the function of multiple devices in traditional casting sand step for regeneration concurrently.Use the described casting sand recycling device of the utility model embodiment can independently finish the casting sand step for regeneration, saved the numerous single-row equipment such as multistage regenerating device, sand sieving machine, magnetic separator, sand temperature modulator and device for transporting objects in traditional casting sand step for regeneration.Having saved the equipment placing space, having enhanced productivity simultaneously, also reduced entreprise cost.
