Description
Technical field
The utility model belongs to the equipment in a kind of lost foam casting, is specifically related to a kind of inside and outside cold water pipe dry sand heat sink.
Background technology
Casting techniques such as disappearance mould and V method all are to use dry moulding, and the molding sand temperature that falls of just having unpacked in producing continuously is often up to 300 ℃ more than-500 ℃, and contact or approaching plastic sheeting and about 70 ℃ softening transforms of EPS mould with molding sand during moulding.The molding sand temperature that will not use continuously rapidly drops to below 60 ℃, promptly unrenewable its moulding.So fall sand temperature problem become these casting techniques of restriction continuously, the principal element of maximization, large-scale production.The medium that reduces the sand temperature has three kinds, i.e. fluorine (with volatile matter such as ether), water, air.Refrigerant cooling effectiveness such as fluorine are the highest, but must use refrigeration compressor, and its cost is too high.Adopt air-cooledly, because the thermal capacity of air is little, cooling effect is poor, and big energy-consuming.The present water-cooled of using is fallen sand temperature equipment and is mainly contained water-cooled ebullated bed, trickle and water-bath cylinder, places the water-cooled comb of sand storage etc., but because its heat exchange area is little, time of contact is short, cooling effect is all not satisfactory.Also having a kind of way with water cooling, is exactly to the direct spray form water in molding sand surface, because water must very fast volatilization, so amount should not be too big.Otherwise sand will lump to influence and carry; Water vapour is too many, influences workshop visibility and operation, effluxes also difficulty.If efflux by sack cleaner, cloth bag can be blocked with sand dust.Moreover, in order to evaporate rapidly, can only be sprayed on the high temperature molding sand behind the firm knockout, the scope of application is limited.Simultaneously, the layer of sand that water smoke can only contact surface, lower floor's sand just cooling less than.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of inside and outside cold water pipe dry sand heat sink, and it adopts water to do medium, and thermal capacity is big, and the heat of taking away is many, and inner and outer pipes is two cold, has improved cooling effectiveness.
The technical solution of the utility model: a kind of inside and outside cold water pipe dry sand heat sink, it comprises sand inlet 1, cold water pipe 2, sand export 3, axle sprocket wheel 4, outer tube 5, interior pipe 6, axis 7, stirrer gear 8, outer tube water inlet 9, outer tube water return outlet 10, helical baffle 11, flange 12, bearing block 13, bearing bracket stand 14, axis water inlet 15 and axis delivery port 16, the upper end of cold water pipe 2 is provided with sand inlet 1, the lower end is provided with sand export 3, be provided with outer tube 5 and interior pipe 6 in the cold water pipe 2, axis 7 is provided with stirrer gear 8 and spiral plate 11, and the two ends of cold water pipe 2 are respectively arranged with bearing block 13 and bearing bracket stand 14; The flange 12 of cold water pipe 2 is connected with bearing block 13, bearing bracket stand 14 respectively; Be respectively arranged with outer tube water inlet 9, outer tube delivery port 10, axis water inlet 15 and axis delivery port 16 on the cold water pipe 2, the termination of axis water inlet 15 is provided with a sprocket wheel 4.
The utility model compared with prior art has following beneficial effect: 1, Yi Shui does medium, and its thermal capacity is big, and the heat of taking away is many.2, water sand drives in the wrong direction, and sand Wen Yigao when water temperature is high has kept the two relative temperature difference, is beneficial to heat exchange, and inner and outer pipes is two cold, has all increased the area of heat exchange between sand water.3, stir cold and hot sand is constantly mixed, each layer sand chance that all is cooled.Thereby improved cooling effectiveness.
